Description of equivalent WO 2004045024 A2

HIGH PERFORMANCE, HIGH CAPACITANCE GAIN, JACK CONNECTOR FOR DATA TRANSMISSION OR THE LIKE

BACKGROUND OF THE INVENTION

The present invention relates generally to electric connectors and, more particularly, to an interference inhibiting, electric connector for use in high frequency data communications or

the like.

Conventional jack connectors for data communications are characterized by a dielectric housing with a series of contacts positioned within the housing in relatively close proximity to one another. The jack contacts establish electrical connection between a corresponding wire conductor at one end of the contact and plug contacts and circuits on a printed circuit board on which the jack is mounted.

In locating the contacts in relative proximity to one another, especially during high performance communications, the contacts themselves become antennae for both broadcasting

and receiving electromagnetic radiation. This leads to signal coupling between different pairs of contacts, a phenomenon commonly known as crosstalk. Crosstalk is a source of interference, characterized quantitatively by a signal-to-noise ratio that degrades the processing of incoming signals. As the frequency of interfering signals due to crosstalk and associated error rate

increases, namely, during high performance communications, crosstalk becomes increasingly significant, often interfering with and otherwise obstructing data transfer.

Efforts have been made to reduce and even eliminate crosstalk in a variety of electrical

applications. Of particular importance, in recent years, has been crosstalk reduction during high speed, high volume data transmission between wireless devices, computers or the like, especially in data streaming and video conferencing applications. Methods for reducing crosstalk have ranged from placement of the contacts in a crossed configuration to altering the geometry of the contacts, such as shown generally in U.S. Patent No. 5,626,497, non-contact overlapping and cross-over of contact-pairs, as provided in U.S. Patent No. 5,362,257, as well as twisting of the contacts with one another.

Geometric variation of the connector structure has also been found helpful in compensating for and/or substantially cancelling crosstalk. Such approaches include minimizing the surface area of contact blades and altering the contacts' placement relative to one another. An example of this approach is provided in U.S. Patent No. 5,586,914.

Still another geometry-related construction for reducing crosstalk, namely, between contacts of two signal pairs, is to form capacitive couplings between the contacts of different signal pairs by utilizing extensions that extend laterally from the respective contacts. For example, U.S. Patent No. 5,547,405 shows a crosstalk suppressing connector with two pairs of signal-carrying contacts. Each secondary contact is capacitively coupled to an initial contact of the other pair by a lateral extension formed in one of the contacts which overlies the other contact in a local region of limited length. This arrangement has also been found beneficial for crosstalk reduction.

Another approach t o crosstalk m itigation h as b een t o s ever s ignal p aths of s elected connector contacts, then re-route them through a filter circuit in order to balance mutual inductance. Balancing inductance is a known crosstalk reducer. Illustrations of such techniques are set forth, for instance, in U.S. Patent Nos.5,470,244 and 5,454,738. Other useful techniques include the p lacement o f dielectric spacers or inserts between contacts within the housing. Representative applications of insulation displacement connectors and dielectric inserts for crosstalk reduction maybe found in U.S. Patent Nos. 5,226,835 and 5,571,035, respectively. Although prior attempts at crosstalk reduction have met with some success, they have been found not only difficult and costly to implement, but also of limited durability and reliability. Moreover, with the ever increasing speed of data communications, crosstalk produced at electric connections has intensified, necessitating further advances in crosstalk inhibition

technology.

An electric connector is, therefore, desired that provides high performance data communication, that is simple and economical to produce, and that facilitates optimum data transfer with increasing frequency of transmission without, signal degradation due to crosstalk.

Referring now to the drawings, and more particularly to FIGS. 1-30, there is shown a

specific, illustrative electric connector jack 1 for data transfer applications or the like, in accordance with the present invention. According to the embodiment shown in FIGS. 1-11, the

assembly includes a jack connector 10 comprising a plurality of contacts 11, preferably at least eight, aπanged in sequential positions designated PI to P8. These contacts are desirably connected in at least four signal pairs, each pair forming part of a respective signal cuπent. By convention, the fourth contact 24 (i.e., the contact occupying position P4) and fifth contact 16 are in a first signal pair, third contact 15 and sixth contact 25 comprise a second signal pair, first contact 13 and second contact 14 are in a third signal pair and seventh contact 32 and eighth contact 33 constitute a fourth signal pair.

The contacts are preferably elongate members formed of a highly electrically conductive material, e.g., commercially pure copper, and are formed so as to be situated in corresponding sequential planes, one next to the other, the planes being substantially parallel to one another. One contact of each contact pair is configured differently from the other contact of the pair. The respective contacts in each contact pair are also oriented relative to one another such that they remain in generally parallel planes, but define non-parallel paths. Alternatively or concuπently, the contacts in each contact pair overlap at least once for added crosstalk inhibition.

Although the present invention has been shown and described with reference to a jack connector with eight conductive contacts operatively engaged in four signal pairs, it will be understood that other numbers of contacts and/or signal pairs, and electric or electronic connector arrangements, maybe utilized, giving consideration to the purpose for which the present invention is intended. In accordance with the invention, as illustrated in FIGS. 6-8, the third contact 15 of the second signal pair and the fifth contact 16 of the first signal pair each mounts, by means of a

connection portion 17a, 18a, a plate-like extension 17, 18, respectively, oriented in a first direction, preferably downwardly from the respective contacts, as shown in FIG. 7, and in respective planes generally parallel to one another. The extensions are separated a selected distance 21 , e.g., about 15 mils to about 17 mils, by a first dielectric 22, e.g., a dielectric polymeric material, air or like gas having dielectric properties, located between them, such that a first capacitor 23 is formed. In the illustrated embodiment wherein the extensions have flat plate configurations, the resulting aπangement is a flat-plate capacitor.

Similarly, as best seen in FIG. 9, each ofthe fourth contact 24 ofthe first signal pair and sixth contact 25 ofthe second signal pair mounts, by means of a connection portion 26a, 27a, a plate-like extension 26, 27, respectively, oriented in a second direction, preferably upwardly from the mounting point on the 'contacts, also in respective planes generally parallel to one another. The extensions are likewise separated a distance 29, e.g., about 15 mils to about 17 mils, by a second dielectric 30, such as a dielectric polymeric material, air or like gas having dielectric properties, such that a second capacitor 31 also of a flat-plate type is formed. A capacitor of this general description is illustrated schematically in FIG. 10.

Alternatively or concuπently, the plate-like extensions ofthe third and fifth contacts and/or the fourth and sixth contacts, respectively, sandwich a dielectric insert or a plurality of dielectric inserts. According to a further embodiment, the respective dielectrics 22, 30 of each contact pair are included in the sandwich of one or more dielectric inserts. In this manner, the housing and the inserts may advantageously be constructed of different dielectric materials, within the spirit and scope ofthe present invention. Other variations of this aπangement will be appreciated based

upon a review of this disclosure.

As shown in FIG. 5, each contact of each signal pair has a plug engaging portion 34 and aboard engaging portion 35. Theplurality of contacts have a selected shape, are aπanged suitably

relative to one another, and are housed collectively by a dielectric housing 40 (best seen in FIGS. 1 and 11) so as to minimize crosstalk during data transfer, especially during high frequency data

communications.

In a further embodiment, one of capacitors 23, 31 is a flat plate capacitor and the other capacitor is of a non-flat plate type. Alternatively, both are non-flat plate type capacitors but are adapted for high capacitance gain production for optimal, passive, electromagnetic interference inhibiting effect. It is additionally prefeπed that each contact and its plate-like extension be constructed, e.g., stamped or cast, either as a one piece unit, as a relatively flat assembly, as a rounded or wire-like assembly, e.g., extruded, and/or in any combination thereof. Also alternatively or concuπently, each contact and associated extension may be formed as separate pieces which are subsequently joined to one another suitably by conventional welding, soldering,

cold or hot rolling techniques and/or using an adhesive.

According to another aspect of the present invention, the total surface area of the extensions of the first capacitor is generally unequal to that of the second capacitor. More particularly, in one embodiment, the surface area ofthe first capacitor extensions is less than that ofthe second capacitor extensions. In another embodiment, the first capacitor extensions have a surface area greater than that ofthe second capacitor extensions. Furthermore, the surface area of the first capacitor extensions may be generally equivalent to that of the second capacitor extensions, within the spirit and scope ofthe present invention. Generally speaking, capacitance gain may be controlled by a variety of factors including, but not limited to, the spacing ofthe extensions forming each capacitor from one another, their dimensions, their surface texture, the nature ofthe dielectric material located in the space between them, and the orientation of the extensions relative to one another. The plate dimensions, the dielectric nature ofthe material between them, and the relative orientation ofthe plates are directly proportional to the compensating contact plate capacitance, whereas the distance of separation

between the plates is inversely proportional thereto. For optimal design, and according to one aspect ofthe present invention, such proportionality is determined by the following mathematical relationship:

c = 22.49e ⁵ (( ε_rx y) / s ) where c = capacitance in pf, ε_r = relative dielectric constant ofthe dielectric material between the plates, x = plate width in mils, y = plate length in mils and s = plate separation distance in mils. The foregoing is considered applicable to a pair of contacts constituting a particular signal pair, each having a plate-like extensions oriented generally parallel to one another, according to various aspects ofthe present invention.

EXAMPLE

To achieve a selected capacitance, in accordance with the present invention, extension plates are used where x = 100 mils, y = 140 mils and s = 17 mils. The plate-like extensions are

positioned generally parallel to one another and a Nalox_® 553 insert is located in the space between them, this material having a relative dielectric constant, ε_r, of about 3.7. Using the above formula, c = 22.49e^'5 (((3.7)(100)(140)/(17)), the plate capacitance is calculated to be 0.685 pf. Although the present invention has been shown and described as utilizing a conventional conductive material for the contacts, such as commercially pure copper, it is understood that

operative components of this invention maybe constructed of other high conductivity materials, giving consideration to the purpose for which the present invention is intended. For example, a copper alloy, silver and/or alloys thereof, aluminum and/or its alloys, fiber optic materials, and

super conductors or the like may also be used, within the spirit and scope ofthe present invention.

In addition, while the present invention has been shown and described as utilizing platelike surfaces, that is, surfaces with a relatively flat, even grade, it is understood that such surfaces maybe polished to a minor-like finish or, in the alternative, textured, provided that any disruption ofthe capacitance gain produced is negligible.

In yet another embodiment, an electric connector for data transfer applications is provided wherein the connector comprises at least four elongate contact members connected in at least two signal pairs. A first signal pair includes a second contact member 24 and a third contact member

16. A second signal pair includes a first contact member 15 and a fourth contact member 25. One member of each pair is configured differently from the other member ofthe pair, the respective members being oriented relative to one another such that they remain in generally parallel planes, but define non-parallel paths. Each ofthe first and third members mounts a plate-like extension 17, 18, respectively, oriented in a first direction and in respective planes generally parallel to one another. The extensions are spaced apart by a selected distance, each pair of extensions being separated by first dielectric 22 such that first capacitor 23 is formed. Each of the second and fourth members mounts a plate-like extension 26, 27, respectively, oriented in a second direction also in respective planes generally parallel to one another. Each pair of extensions are likewise separated, i.e., by second dielectric 30, such that second capacitor 31 is formed. Each contact member of each signal pair has plug engaging portion 34 and a board engaging portion 35, the plurality of contact members having a selected shape, being aπanged relative to one another, and

being housed collectively by a dielectric casing so as to minimize crosstalk during data transfer.

Generally speaking, according to one embodiment ofthe present invention best seen in FIGS. 1-5, the structure of housing 40 has a contact locating sub-assembly 41 which not only forms dielectrics 22, 30 between respective plate extensions, but also effectively creates the first

and second capacitors. In this connection, the housing is constructed, at least in part, of a dielectric polymeric material or the like, e.g., Nalox_® 553, having a relatively high dielectric value.

More particularly, sub-assembly 41 includes a base portion 42 and a lid portion 48, the base portion being formed suitably for receiving each signal pair and retaining the contacts of each pair in the desired aπangement, i.e., relative to one another and the housing. Preferably, the surface ofthe structure is configured so as to rise and fall stepwise across its width. This rise and fall pattern forms generally rectangular steps 43 rising from the surface, i.e., where the surface rises and then falls. Where the surface falls and then rises in a rectangular-like fashion, contact receiving detents or channels 44 are formed. The detents desirably have a width suitable for receiving and snugly engaging their respective contacts and extensions thereof. Alternatively, the width is adapted for a loose fit with the respective contact and extensions, the contact being

secured in the detent using a suitable adhesive or the like.

Between the respective contacts of each pair, the structure rises stepwise so as to form dielectrics 22, 30, respectively, between them. Further alternatively or concuπently, the dielectrics

are formed, at least in part, by complementary mating falls 45 and rises 46 in the sub-assembly lid portion 48, best seen in FIG. 2, which is placed over the base portion-supported assembly of contacts, thereby securing the contacts within sub-assembly 41. By forming the dielectric in this fashion, crosstalk inhibiting properties ofthe present invention are enhanced.

Referring now to another aspect of the present invention, a high performance, high capacitance gain j ack connector 50 is provided for high frequency data transfer applications or the like. As shown in FIG. 12, a plurality of elongate contact members 51 consist of at least eight wires aπanged in sequential positions and connected in a series of four signal pairs. The first signal pair comprises a fourth wire 53 paired with a fifth wire 54. A third wire 52 and a sixth wire 55 comprise a second signal pair. First wire 56 and second wire 57 are in a third signal pair and

seventh wire 58 and eighth wire 59 constitute a fourth signal pair. The third and fifth wires each mount plate-like extensions (not shown) oriented in a first direction and in respective planes generally parallel to one another. The extensions are separated a selected distance by a first dielectric 60, e.g., aportion ofthe housing, an insert or the like, having a relatively high dielectric value, such that a first high gain capacitor for minimizing crosstalk is formed.

Likewise, the second and fourth wires each mount a plate-like extension (not shown) oriented in a second direction, e.g., generally opposite to that of the first direction, and in respective planes generally parallel to one another. Similarly, these extensions are separated selected distances by a second dielectric 61 having a relatively high dielectric value such that a second high gain, flat plate capacitor for minimizing crosstalk is formed.

Finally, each wire has aplug engaging portion 62, e.g., of a conventional type (not shown), and a board engaging portion 63. The wires also have a selected shape, are aπanged relative to one another, and are housed collectively by a dielectric casing 64 so as to minimize crosstalk during high frequency data transfer. Alternatively or concuπently, at least one ofthe elongate contact members, illustrated in FIGS. 1 and 11, includes a wire, hi one embodiment, each member includes at least one wire-like

portion that is relatively circular in diameter, generally oval in diameter, or in any combination thereof. In addition, such wire-like portions are optionally formed of sections having increased

diameter, reduced diameter and/or relatively flattened portions suitable for accommodating

coπesponding geometry ofthe dielectric housing, in accordance with the present invention.

Turning now to another alternative embodiment of the present invention, as shown in FIGS . 13 -21 , a dielectric housing 80 is provided having a sub-assembly 81 is constructed in upper and lower contact receiving parts 82, 83, respectively. Each part is formed suitably for receiving coπesponding signal pairs and retaining the contacts of each pair in the desired aπangement, i.e., relative to one another and the housing. As with the prior embodiments, the fourth contact 24 and fifth contact 16 are in a first signal pair, third contact 15 and sixth contact 25 comprise a second signal pair, first contact 13 and second contact 14 are in a third signal pair and seventh contact 32 and eighth contact 33 constitute a fourth signal pair.

More particularly, the upper part 82 is configured for receiving the first contact 13, second contact 14, third contact 15 and fourth contact 24. The lower part 83 is formed suitably for receiving the fifth contact 16, sixth contact 25, seventh contact 32 and eighth contact 33. Upon engagement ofthe first part with the second part, e.g., by friction fit, snap engagement or the like, the first through eighth contacts are located in their respective positions PI through P8.

As illustrated in FIGS. 19-21, the third contact 15 ofthe second signal pair and the fifth contact 16 ofthe first signal pair each mounts, by means of connection portions 17a, 18a, a platelike extension 17, 18, respectively, oriented in a first direction, preferably downwardly from the respective contacts, and in respective planes generally parallel to one another. The extensions are separated a selected distance, e.g., about 15 mils to about 17 mils, by first dielectric 22, e.g., a n dielectric polymeric material, air or like gas having dielectric properties, located between them, such that first capacitor 23 is formed. In the illustrated embodiment wherein the extensions have flat plate configurations, the resulting aπangement is a flat-plate capacitor.

Similarly, each ofthe fourth contact 24 ofthe first signal pair and sixth contact 25 ofthe

second signal pair mounts, by means of connection portions 26a, 27 a, the plate-like extension 26,

* 27, respectively, onented m a second direction, preferably downwardly from the mounting point

on the contacts, also in respective planes generally parallel to one another. The extensions are likewise separated a distance, e.g., about 15 mils to about 17 mils, by second dielectric 30, such as a dielectric polymeric material, air or like gas having dielectric properties, such that second capacitor 31 is formed.

Alternatively, or in addition to the aπangement discussed above, the eighth contact 33

mounts, by means of conriection portion 28a, aplate-like extension28 oriented in a third direction. The third direction is preferably directed downwardly from the mounting point on the contact and in a plane generally parallel to that of plate-hke extension 27. Extensions 27 and 28 are separated a selected distance 38 by a third dielectric 36, such as a dielectric polymeric material, air or like gas having dielectric properties, such that third capacitor 37 is formed.

Preferably, the surface of the structure is configured, as with the other embodiments described herein, so as to rise and fall stepwise across its width. This rise and fall pattern forms generally rectangular steps 84 rising from the surface, i.e., where the surface rises and then falls.

Where the surface falls and then rises in a rectangular-like fashion, contact receiving detents or channels 85 are formed. The detents desirably have a width suitable for receiving and snugly engaging their respective contacts and extensions thereof. Alternatively, the width is adapted for a loose fit with the respective contact and extensions, the contact being secured in the detent using

a suitable adhesive or the like.

Between the respective contacts of each pair, the structure rises stepwise so as to form dielectrics 22, 30, 36, respectively, between them. Further alternatively or concuπently, the dielectrics are formed, at least in part, by complementary mating falls 86 and rises 87 in the sub- assembly lower portion 83 which is placed over the base portion-supported assembly of contacts,

thereby securing the contacts within sub-assembly 81, as shown in FIG. 21. By forming the

dielectric in this fashion, crosstalk inhibiting properties ofthe present invention are enhanced.

Still a further embodiment ofthe present invention is shown in FIGS.22-30. According

to this embodiment, there is provided a high performance, high capacitance gain, electric connector for data transfer applications, which also comprises at least eight sequentially positioned contacts connected in a plurality of signal pairs. A first signal pair includes a fourth contact 24 and a fifth contact 16. A second signal pair includes a third contact 15 and a sixth contact 25. A third signal pair comprises a first contact 13 and a second contact 14. Similarly, a seventh contact 32 and an eighth contact 33 are in a fourth signal pair.

It is prefeπed that one contact of each pair be configured differently from the other contact of the pair, and that the respective contacts be oriented relative to one another such that they

substantially remain in generally parallel planes, but define non-parallel paths. Also, as best seen in FIGS.22-25, one contact of each ofthe first, third and fourth signal pairs desirably crosses over the other contact ofthe pair such that the positions occupied by the respective contacts along their non-parallel paths are substantially reversed. Taken in combination with the various contact configurations ofthe present invention, such a cross over aπangement has been found particularly effective at further enhancing the crosstalk inhibiting characteristics of connectors set forth herein. As illustrated in FIGS.22-26D, the third contact 15 ofthe second signal pair and the fifth contact 16 ofthe first signal pair again each mounts, by means of a connection portion 17a, 18a, a plate-like extension 17, 18, respectively, oriented in a first direction, preferably downwardly from the respective contacts, and in respective planes generally parallel to one another. The extensions are separated at selected distance 21, e.g., about 15 mils to about 17 mils, by first dielectric 22 such that a first capacitor 23 is formed.

Similarly, as best seen in FIGS .22-25 and 27-27D, each ofthe fourth contact 24 ofthe first signal pair and sixth contact 25 ofthe second signal pair mounts, by means of connection portions 26a, 27a, the plate-like extension 26, 27, respectively, oriented in a second direction, preferably a direction substantially the same as the first direction, from the mounting point on the contacts, also in respective planes generally parallel to one another. Alternatively, the second direction is generally opposite that ofthe first direction, i.e., in an upward direction. Further alternatively, it is desired that both the first and second directions be generally upward. The extensions are likewise separated distance 29, e.g., about 15 mils to about 17 mils, by the second dielectric 30 such that a second capacitor 31 is formed.

Also alternatively or concuπently, the plate-like extensions ofthe third and fifth contacts

and/or the fourth and sixth contacts, respectively, sandwich a dielectric insert or a plurality of dielectric inserts. In yet another embodiment, the respective dielectrics 22, 30 of each contact pair are included in the sandwich of one or more dielectric inserts.

As shown generally in FIGS .22-29, each contact of each signal pair is provided with plug engaging portion 34 and board engaging portion 35. The plurality of contacts have a selected shape, are aπanged suitably relative to one another, and are housed collectively by dielectric housing 90 (see FIGS. 28 and 29) so as to πunimize crosstalk during data transfer, especially

during high frequency data communications.

Further alternatively or concuπently, as also shown in FIGS. 28 and 29, the dielectric housing 90 includes a sub-assembly or contact receiving part 91 formed suitably with upper and lower contact receiving portions 92, 93 , respectively, for receiving coπesponding signal pairs and

for retaining the contacts of each pair in the desired aπangement, i.e., relative to one another and

the housing.

More particularly, each ofthe upper and lower portions 92, 93 is configured for receiving coπesponding inwardly facing portions ofthe first contact 13 , second contact 14, third contact 15 , fourth contact 24. fifth contact 16, sixth contact 25, seventh contact 32 and eighth contact 33. From the perspective ofthe plug engaging portions ofthe contacts, the fourth contact 24 and fifth

contact 16 are in a first signal pair, third contact 15 and sixth contact 25 comprise a second signal pair, first contact 13 and second contact 14 are in a third signal pair and seventh contact 32 and eighth contact 33 constitute a fourth signal pair. Hence, upon engagement of each contact with its coπesponding, suitably shaped, upper and lower contact receiving portion, e.g., by friction fit, snap engagement or the like, the first through eighth contacts are located in their respective positions PI through P8.

Relative to the contacts' board engaging portions, the sequential positions designated PI to P8 of the first, third and fourth signal pairs are reversed, namely, the fourth contact 24 now occupies position P5 and fifth contact 16 is in position P4, the first contact 13 is now in position

P2 whereas second contact 14 occupies position PI, and, finally, the seventh contact 32 occupies position P8 while the eighth contact 33 is now in position P7. The sequential positions of the second signal pair, i.e., the third contact 15 and sixth contact 25, remain the same. Preferably, the surface of the structure is configured, as with the other embodiments

described herein, so as to rise and fall stepwise across its width. This rise and fall pattern forms

generally rectangular steps 94 rising from the surface, i.e., where the surface rises and then falls. Where the surface falls and then rises in a rectangular-like fashion, contact receiving detents or channels 95 are formed. The detents desirably have a width suitable for receiving and snugly engaging their respective contacts and extensions thereof. Alternatively, the width is adapted for a loose fit with the respective contact and extensions, the contact being secured in the detent using

a suitable adhesive or the like.

Between the respective contacts of each pair, the structure rises stepwise so as to form dielectrics 22, 30,τespectively, between them. Further alternatively or concuπently, the dielectrics are formed, at least in part, by with complementary falls and rises forming channels 96 in the sub- assembly lower portion 93 adapted for receiving the plug engaging portions of the contacts, thereby securing the contacts and their arc shaped portions about sub-assembly 91, as best seen in FIGS. 22 and 23. By forming the dielectric in this fashion, crosstalk inhibiting properties of the present invention are enhanced.

Referring now to another aspect of the present invention, a method is provided for assembling an electric connector for data transfer applications. First, at least four elongate contact members are connected in at least two signal pairs. A second one ofthe contact members is paired with a third one of the contact members to form a first signal pair. A first one of the contact

members is paired with a fourth one ofthe contact members to form a second signal pair. Such pairing is done such that one contact member of each contact member pair is configured differently from the other contact member of the pair, the respective contact members being

oriented relative to one another such that they remain in generally parallel planes, but define non- parallel paths. Next, a plate-like extension is mounted to each of the first and third contact

members. Each plate-like extension is oriented in a first direction and in respective planes generally parallel to one another, and eachpair of extensions are separated by a first dielectric such that a first capacitor is formed. Thereafter, a plate-like extension is mounted to each ofthe second and fourth contact member. Each plate-like extension is oriented in a second direction and in respective planes generally parallel to one another, and each pair of extensions are separated by

a second dielectric such that a second capacitor is formed. Finally, a plug engaging portion and a board engaging portion is formed on each contact member pair, the plurality of contact members having a selected shape, being aπanged relative to one another, and being housed collectively by a dielectric casing so as to minimize crosstalk during high frequency data transfer.

According to a further aspect ofthe present invention is a method of assembling an electric connector for data transfer applications. Initially, the plurality of at least eight elongate contact members, i.e., the first through eighth contact members, are connected in a series of at least four signal pairs. The fourth and fifth contact members form a first signal pair. A second signal pair

is formed by the third contact member and the sixth contact member. The first and second contact members form a third signal pair. Finally, the seventh contact member and the eighth contact member form a fourth signal pair.

One contact member of each pair is configured differently from the other member ofthe pair. The respective contact members of each signal pair are also oriented relative to one another such that they remain in generally parallel planes, but define non-parallel paths. In an alternative

embodiment, the respective contact members overlap at least once.

A plate-like extension is mounted to each ofthe third and fifth contact members such that the extensions are oriented in first directions and in respective planes generally parallel to one another. The extensions are separated a selected distance by the firet dielectric such that the first

capacitor is formed.

Thereafter, plate-like extensions oriented in a second direction, e.g., generally opposite to the first direction, and situated in respective planes generally parallel to one another, are similarly mounted to the fourth and sixth contact members. The extensions are likewise separated a selected distance by the second dielectric such that the second capacitor is formed. Finally, each contact member of each signal pair is provided with the plug engaging portion and the board engaging portion. The plurality of members are formed of the selected shape, aπanged relative to one another, and housed collectively by the dielectric casing so as to minimize crosstalk during

high frequency data transfer.

Alternatively, another method of assembling an electric connector is performed by first forming the plurality of elongate contact members such that each member has a plug engaging portion and a board engaging portion. At least two ofthe members are formed so as to have the plate-like extension oriented in the first direction and in respective planes generally parallel to one another. Also, at least two members are formed with the plate-like extension oriented in the second direction, e.g., generally opposite to that ofthe first direction, and in respective planes generally parallel to one another. Finally, each ofthe members are formed of a selected shape suitable for minimizing crosstalk during high frequency data transfer.

Next, the contact members are aπanged in sequential positions and connected in the series of signal pairs. In particular, the fourth contact member is paired with the fifth contact member to form the first signal pair. The third contact member is paired with the sixth contact member to form the second signal pair. The first contact member is paired with the second contact member to form the third signal pair, and the fourth signal pair is formed by pairing the seventh and eighth contact members. The contact members are formed such that one contact member of each pair is configured differently from the other contact member ofthe pair. In addition, the respective contact members of each pair are oriented relative to one another such that they remain in generally parallel planes, but define non-parallel paths. Alternatively or concuπently, the respective contact members of each pair overlap at least once.

Thereafter, each of the two contact members having capacitor-forming plate-like extensions, e.g., each ofthe two contact members having plate-like extensions oriented in the first direction and in respective planes generally parallel to one another, are separated a selected distance by the first dielectric. This forms the first capacitor. Likewise, each ofthe two members having plate-like extensions oriented in the second direction generally opposite to that ofthe first direction (and in respective planes generally parallel to one another) are separated a selected distance by the second dielectric such that the second capacitor is formed. Finally, the member pairs are aπanged relative to one another and housed collectively by the dielectric casing so as to minimize crosstalk during high frequency data transfer.

In still another embodiment ofthe present invention, a method is provided for assembling an electric connector for data transfer applications. First, at least four elongate contact members are connected in at least two signal pairs. A second one ofthe contact members is paired with a third one ofthe contact members to form a first signal pair. A first one ofthe contact members is paired with a fourth ofthe contact members to form a second signal pair. Such pairing is done

such that one contact member of each contact member pair is configured differently from the other contact member ofthe pair, the respective contact members being oriented relative to one another such that they substantially remain in generally parallel planes, but define non-parallel paths. Such pairing is also done such that one member of each signal pair crosses over the other member of the pair so that the positions occupied by the respective members along their non-parallel paths are reversed.

Next, a plate-like extension is mounted to each of the first and third contact members.

Each plate-like extension is oriented in a first direction and in respective planes generally parallel

to one another, and each pair of extensions are separated by a first dielectric such that a first capacitor is formed. Thereafter, a plate-like extension is mounted to each ofthe second and fourth contact members. Each plate-like extension is oriented in a second direction and in respective planes generally parallel to one another, and each pair of extensions are separated by a second dielectric such that a second capacitor is formed.

Finally, a plug engaging portion and a board engaging portion is formed on each contact member pair, the plurality of contact members having a selected shape, being aπanged relative

to one another, and being housed collectively by a dielectric casing so as to minimize crosstalk during high frequency data transfer.

According to a further aspect of the present invention, there is provided a method for assembling a electric connector for data transfer applications. Initially, at least eight elongate contact members are connected in a series of four signal pairs. A fourth one of the contact members is paired with a fifth one of the contact members so as to form a first signal pair. A second signal pair is formed of a third one ofthe contact members and a sixth one ofthe contact members. Then, a first one ofthe contact members and a second one ofthe contact members are formed in a third signal pair. Finally, a seventh one ofthe contact members and an eighth one of the contact members are aπanged to form a fourth signal pair.

One contact member of each contact member pair is configured differently from the other member ofthe pair, the respective members being oriented relative to one another such that they substantially remain in generally parallel planes, but define non-parallel paths. Also, one contact member of each ofthe first, third and fourth signal pairs crosses over the other contact member ofthe pair such that the positions occupied by the respective contact members along their non- parallel paths are reversed.

Each ofthe third and fifth contact members mounts a plate-like extension oriented in a first direction and in respective planes generally parallel to one another. Each pair of extensions are separated by a first dielectric such that a first capacitor is formed. Furthermore, each ofthe fourth

and sixth contact members mounts a plate-like extension oriented in a second direction and also in respective planes generally parallel to one another. Each pair of extensions are likewise separated by a second dielectric such that a second capacitor is formed.

Finally, each contact member of each contact member pair has aplug engaging portion and a board engaging portion, the plurality of contact members having a selected shape, being aπanged relative to one another, and being housed collectively by a dielectric casing so as to minimize

crosstalk during high frequency data transfer.

In operation, the present invention provides optimum inhibition of electromagnetic interference during high performance transfer of data between electronic devices. Initially, as illustrated in FIG. 30, a first electronic device 71, e.g., a conventional desktop computer, laptop, videophone, telephone or the like, is joined to jack connector 72. Next, a second electronic device

73 preferably similar to the first is, in turn, joined to a plug connector 74. Finally, the plug connector is inserted into the jack connector such that an electrical connection is established

between the first and second electronic devices.

It is prefeπed that the electric connector comprise a plurality of contacts aπanged in sequential positions and connected in at least two signal pairs, as illustrated above. The first signal pair comprises a second contact 24 and a third contact 16, and the second signal pan- comprises a first contact 15 and a fourth contact 25. Each ofthe first and third contacts mounts

plate-like extension 17, 18, respectively, oriented in the first direction and in respective planes generally parallel to one another. The extensions are separated the selected distance 21 by first dielectric 22 such that the first capacitor is formed. Similarly, each of the second and fourth contacts mounts plate-like extensions 26, 27, respectively, oriented in the second direction, e.g.,

generally opposite to that of the first, and also in respective planes generally parallel to one another. The extensions are likewise separated a selected distance 29 by second dielectric 30 such that the second capacitor is formed. Each contact pair has plug engaging and board engaging portions. Further, each ofthe plurality of contacts has the selected shape, is aπanged relative to

one another, and is housed collectively by the dielectric casing so as to minimize crosstalk during data transfer.

Alternatively or concuπently, as will be appreciated by those skilled in the art, at least one of the devices, as shown in FIG. 30, is linked to another by an interactive communications network 75, e.g., the Internet, an intranet and/or extranet, a wireless data transmission network, or a combination ofthe two. Exemplary linking components 76, 77 of communications network 75 include, but are not limited to, wire, fiber optic cable or the like. Also alternatively or

concuπently, the first and second electronic devices include a conventional cell phone, personal digital assistant or the like.

While the present invention has been shown and described as apassive connector, i.e., one having no on-board circuitry or other devices for signal conditioning, it is understood that it may be used as an integrated connector such as a connector having a filter circuit, giving consideration to the purpose for which the invention is intended. Overall, the present invention is advantageous in providing an improved electric connector, a method of assembling the connector, and a method of using the same for high performance data communications. The c onnector and associated methods are not only simple, practical and economical to implement and produce, but also maintain an optimum level of data transfer as the frequency of transmission increases, all without signal degradation due to crosstalk. The present invention also provides the benefits of enhanced crosstalk compensation and reduction passively, even during the highest performance of applications. This is accomplished, at least in part, through implementation of high capacitance gain producing capacitors within the wire sets. In this manner, the invention provides means for virtually eliminating crosstalk during high frequency communications, that maybe readily integrated in the design of existing electric connectors with minimal redesign.

Various modifications and alterations to the present invention maybe appreciated based on a review of this disclosure. These changes and additions are intended to be within the scope and spirit of this invention as defined by the following claims.
