Floating connector and manufacturing method thereof

Technical field

The invention relates to a floating connector and a manufacturing method thereof.

Background technique

When two circuit boards are connected to each other, for example, a technique can be used in which a female connector is fastened to the circuit board and a male connector is fastened to the other circuit board, and the female and male connectors are connected The devices are matched and connected with each other. It may happen that the position of the pair of mating connectors has been predetermined on the circuit board, so that the degree of freedom is relatively restricted. When attempting to fit the two connectors in this situation, unless one of them is flexible, not only will the two not be able to fit and connect normally, but one or the contacts of one of them will be damaged or permanently deformed. , Making the reliability of this connection lack.

In order to solve the above problems, a so-called floating connector has been proposed, in which the mating part of one of the connectors (that is, the mating part that cooperates with the mating connector) is configured so that the mating part can be fastened relative to the connector The surface of the circuit board is elastically movable at least in the horizontal direction, so as to absorb strain when mated with the mating connector.

For example, the connectors shown in FIGS. 7(A), 7(B), 8(A) to 8(C) are known as such floating connectors (see Patent Reference 1).

In Figures 7(A) and 7(B), the floating connector 101 is fastened to a circuit board PCB, and is connected to another circuit board PCB perpendicular to the first circuit board PCB. 131 is matched and connected. The mating connector 131 includes a housing 140 extending in the longitudinal direction (that is, the direction perpendicular to the plane of FIG. 7(A) or the left-to-right direction of FIG. 7(B)) and a plurality of plugs attached in two rows along the longitudinal direction of the housing 140 Contacts 150. Each plug contact 150 includes a board connection part soldered to the second circuit board PCB, and a plug contact part extending vertically downward from the board connection part.

The floating connector 101 includes a housing 110 that extends in the longitudinal direction (the direction perpendicular to the plane of FIG. 7(A) or the left-to-right direction of FIG. 7(B)), and the housing 110 is attached in two rows in the longitudinal direction of the housing 110. Pieces of contact 120.

Each contact 120 includes a fastening part 121 fastened to the housing 110, a solder tip part 123 connected to the first circuit board PCB, and a pair of contact parts 124 contacting the corresponding plug contact 150. These contact pieces 120 are formed by punching and molding a metal plate. It can be clearly seen from FIGS. 8(A) to 8(C) that the fastening portion 121 is basically formed in a box shape, and includes a pair of side walls 121a separated from each other at a specific interval in the longitudinal direction of the housing 110, from one side The front end of the wall 121a (the lower end of FIG. 8(C)) extends in the longitudinal direction to the front end wall 121b that is basically the center between the pair of side walls 121a, and the rear end connecting the rear ends of the pair of side walls 121a The wall 121c, in addition, the connecting portion 122 extending backward to the center of the fastening portion 121 perpendicular to the longitudinal direction is formed by being bent on the end of the front end wall 121b of the fastening portion 121, and the tip portion 123 is welded at the same time. The rear end of the connecting portion 122 extends downward. In addition, at this time, the contact portion 124 extends upward from each side wall 121 a of the fastening portion 121, and contact protrusion portions are formed on the opposite surfaces of the tips of the contact portions 124.

The floating connector 101 is mounted on the circuit board PCB by soldering the soldering tip 123 of the contact 120 to the circuit board PCB, as shown in FIGS. 7(A) and 7(B). In addition, when the mating connector 131 is mated with the floating connector 101, the plug contact 150 contacts the contact protrusion 125 of the contact 120 to form an electrical connection between these connectors. In this case, since there is a solder tip portion 123 extending downward from the connecting portion 122 extending toward the center of the fastening portion 121, the floating connector 101 is configured such that the connector is at least relative to the first circuit board. The PCB surface is elastically moved in the horizontal direction (the longitudinal direction of the housing 110 and the direction perpendicular to the longitudinal direction) in order to absorb the strain formed when the mating connector 131 is mated.

As another example, the connector shown in FIG. 9 is known as another example of a floating connector, which is designed to absorb the strain generated at this time when mated with a mating connector (refer to Patent Document 2).

In FIG. 9, the floating connector 201 is fastened to the surface of a circuit board (not shown), and is connected to a mating connector (not shown) fastened to another circuit board (not shown). Match and connect.

The floating connector 201 includes a first housing 210 that is substantially frame-shaped and extends longitudinally, and a second housing 220 that is inserted into the hole 211 in the housing 210 to leave a gap. A plurality of contact members 230 arranged in a row along the longitudinal direction are attached to the second housing 220.

Each contact 230 includes a fastening portion 231 for fastening the second housing 220, a strain absorbing portion 232, a board connection portion 233 connected to the circuit board, and a contact portion 234 contacting a mating contact (not shown). These contact pieces 230 are substantially flat. The fastening portion 231 is substantially rectangular, and is specially formed by punching a metal plate. The strain absorbing part 232 forms an elastic shape, extends from the lower end of the fastening part 231 through many curved parts, and is specially formed by punching a metal plate. The plate connecting portion 233 is formed to extend downward from the end of the strain absorbing portion 232, and is formed by punching and molding a metal plate. In addition, the pair of contact portions 234 extend upward from the fastening portion 231, and the contact protrusions 235 are formed on the surfaces of the tips of the contact portions 234 facing each other.

The floating connector 201 is mounted on the circuit board by soldering the board connection portion 233 of the contact 230 to the circuit board. Then, when the mating connector is mated with the floating connector 201, the mating contact is connected with the contact protrusion 235 of the contact 230, and an electrical connection is established between these connectors. In this case, the second housing 220 of the floating connector 201 is configured so that the housing is at least elastically movable in the horizontal direction (the longitudinal direction of the second housing 220 and the direction perpendicular to the longitudinal direction). The reason is that the board connecting portion 233 extends downward from the strain absorbing portion 232 formed by many curved portions in an elastic form, so that the strain generated when mated with the mating connector is absorbed.

(Patent Document 1) Japanese Utility Model Application (Publication) No. Showa S64-16084 (Patent Document 2) Japanese Patent Application (Publication) No. Heisei H4-370677 However, the following problems are encountered in the above-mentioned conventional floating connector The problem.

First of all, in the case of the floating connector 101 shown in Figs. 7(A), 7(B), 8(A) to 8(C), due to the use of a complex die-pressing after punching the metal plate to produce the contact 120, this connector is poor in productivity of the contact 120. In addition, since the fastening portion 121 of the contact piece 120 is basically formed into a box shape, the size of the contact piece 120 is relatively large in the longitudinal direction of the housing 110 and in the direction perpendicular to the longitudinal direction, so it is difficult to use such a connector in the current compact height. In density electronic devices. In addition, when there are many contact pieces 120 fastened to the housing 110, these contact pieces will not all be attached to the housing 110 at the same time. On the contrary, each contact piece 120 is cut from the contact piece carrier. Then they are attached to the housing 110 respectively. Therefore, this connector is poor in assembly efficiency.

In addition, in the case of the floating connector 201 shown in FIG. 9, in the manufacture of the contact 230, the contact 230 is exclusively formed of a punched metal plate except for the base connection part 233, so the productivity of the contact 230 is good. However, when these contact pieces 230 are fastened to the second housing 220, they cannot be fastened to the housing 220 all at once. Instead, the contact pieces 230 are respectively attached to the housing 220 after being cut by the contact piece carrier. On the second shell. Therefore, this connector is low in its assembly efficiency. The planes of the strain absorbing member 232 and the base connecting member 233 attached to the contact carrier are in a state where the metal plate is punched, and the row arrangement direction of the contact 230 (the contact 230 is in the form of a row in the first The arrangement in the two shells 220, that is, the longitudinal direction of the second shell 220) is different; therefore, these contact pieces 230 cannot be inserted into the second shell 220 at the same time. In addition, since the contact pieces 230 are all formed in a substantially flat shape, the size of each contact piece 230 in the direction of the attachment pitch, that is, the longitudinal direction of the second housing 220 is small, but since the strain absorbing portion 233 of each contact piece 230 is Through the extension of many curved parts, the contact piece 230 has a larger size along the direction perpendicular to the longitudinal direction. Therefore, it is difficult to use this connector in the current compact and high-density electronic devices.

One of its objectives is to provide a floating connector that is superior in terms of contact productivity and connector assembly efficiency, and this connector allows a compact, high-density structure to be obtained.

The floating connector of claim 2 in the invention of claim 1 allows the position of the elastic portion to be displaced along the axial direction of the contact member, so that the elastic portions of adjacent contact members do not interfere with each other when many contact members are punched out. .

In addition, the manufacturing method of the floating connector of claim 3 includes the following steps: punching out a plurality of contact pieces arranged in a single row, wherein each contact piece has a fastening part fastened to the housing and a corresponding mating part. The contact part of the contact, the lead part connected to the circuit board, and the curved elastic part provided between the fastening part and the lead part, and the position of these elastic parts is displaced along the axial direction of the contact to make the adjacent The elastic parts of the contact pieces do not interfere with each other; a bent part is provided between the fastening part and the elastic part or between the elastic part and the lead part of each contact piece, so that the lead parts of the multiple contact pieces are arranged in a staggered configuration ; The multiple contact pieces arranged in a row are inserted into the housing at the same time; and then the tip of the lead part of each contact piece is cut off from the contact piece carrier.

Figures 1 (A) to 1 (D) show the floating connector of the present invention, in which Figure 1 (A) is a top view, Figure 1 (B) is a front view, Figure 1 (C) is a bottom view, and Figure 1 ( D) is the right view. Fig. 2 is a cross-sectional view taken along line 2-2 in Fig. 1(B). Fig. 3 is a plan view of a state where many contacts have been punched out of the blank. 4(A) and 4(B) are plan views of a state where the contact member shown in FIG. 3 has been compression-molded. Figure 5 is a cross-sectional view of the mating connector. Fig. 6 is a cross-sectional view showing a state where the mating connector shown in Fig. 5 has been mated with the floating connector shown in Figs. 1(A) to 1(D).

In FIG. 6, the floating connector 1 is fastened to one circuit board PCB1, and is matched and connected with a mating connector 50 fastened to another circuit board PCB2. As shown in FIG. 5, the mating connector 50 includes an insulating housing 51 extending in the longitudinal direction (that is, the direction perpendicular to the surface of FIG. 5) and a plurality of mating contacts 52, which are attached in two rows along the longitudinal direction of the housing 51, A connector receiving recess 58 extending in the longitudinal direction is formed in the housing 51. In addition, the positioning rod 56 is shaped so that it protrudes from both ends of the lower surface of the housing 51 with respect to the longitudinal direction, and the guide rod 57 is shaped so that it protrudes from both ends of the upper surface of the housing 51 with respect to the longitudinal direction. Each mating contact 52 includes a fastening portion 53 fastened to the housing 51, a board connection portion 54 extending downward from the lower end of the fastening portion 53 and soldered to another circuit board PCB, and a fastening portion 53 The upper end of the connector receives the elastic contact portion 55 extending in the recess 58.

As shown in Figs. 1(A) to 1(D) and Fig. 2, the floating connector 1 includes an insulating housing 10 extending in the longitudinal direction (the left-right direction of Fig. 1(B) or the direction perpendicular to the plane of Fig. 2). And many contact members 30 arranged in two rows along the longitudinal direction of the housing 10.

The casing 10 includes a main body portion 11 extending in the longitudinal direction and a mating portion 12 protruding from the upper surface of the main body portion 11 and extending in the longitudinal direction. The casing is formed by molding insulating synthetic resin. An orifice portion 13 is formed with respect to the main body portion 11 in the front-rear direction (the left-right direction in FIG. 2) and opens in the bottom direction of the main body portion 11. In addition, a mating connector receiving recess 14 for receiving the housing 51 of the mating connector 50 is formed in the mating portion 12 along this longitudinal direction. In the inner center of the mating connector receiving recess 14, a partition 15 protruding from the bottom of the recess 14 and inserted into the connector receiving recess 58 of the mating connector 50 is formed. The guide rod receiving recess 16 for receiving the guide rod 57 of the mating connector 50 is formed in the two outer ends of the mating connector receiving recess 14 with respect to the aforementioned longitudinal direction.

The lead portions of the contact pieces 30 of each row are arranged in a staggered configuration along the row arrangement direction of the contact pieces 30, so that the contact pieces 30 are constructed by the contact pieces 30A and 30B: the lead portion 34A of the contact piece 30A is arranged at The lead portion 34B of the contact 30B is provided on the inner side.

As shown in FIGS. 1(A) to 1(D), 2 and 4(A) and 4(B), each contact 30A includes a tight fitting that is fastened to the bottom wall of the mating portion 12 of the housing 10 by press-fitting. The fixed portion 31A, the curved portion 32A that is bent outward from the lower end of the fastening portion 31A and has a specific length, the elastic portion 33A that is bent downward from the tip of the curved portion 32A and is parallel to the fastening portion 31A, and the portion extending downward from the elastic portion 33A The lead portion 34A and the contact portion 35A extending upward from the fastening portion 31A. Each contact 30A is formed by punching and molding a metal plate. In each contact 30A, the flat surfaces of the fastening portion 31A, the elastic portion 33A, the lead portion 34A, and the contact portion 35A all extend along the row arrangement direction of the contact 30 (ie, the longitudinal direction of the housing 10). As shown in FIG. 2, the contact portion 35A is arranged at a specific pitch on the two side surfaces of the partition 15 through the two rows of contact pieces. As shown in FIG. 2, the curved portion 32A is used when the fastening portion 31A is joined to the mating The bottom wall of the portion 12 is positioned in the corresponding aperture portion 13 of the main body portion 11 of the housing 10. As shown in Figures 1(A) to 1(D), 2, 4(A), and 4(B), the elastic portion 33A is located in the orifice portion 13 and is formed in a substantially reverse S-shaped curve shape, so that The mating portion 12 can be elastically moved relative to the upper surface of the circuit board PCB1 along the longitudinal direction of the housing 10 and relative to the longitudinal direction (ie along the X direction and the Y direction along the upper surface of the circuit board PCB1). In addition, with respect to the so-called Z direction perpendicular to the upper surface of the circuit board PCB1, the contact portion 35A is set to a sufficient length to enable floating in this Z direction. In the direction perpendicular to the longitudinal direction of the housing 10, since the elastic portion 33A and the lead portion 34A extend from the end of the bent portion 32A to the circuit board PCB with a relatively large length, elastic movement is possible. Furthermore, when the lead part 34A passes through the alignment hole 24 of the toothed plate 20 (described later), the protrusion 36A that sits on the toothed plate 20 is formed on the side portion of the lead part 34A.

The basic structure of each contact piece 30B is similar to that of the contact piece 30A, including a fastening portion 31B that is fastened by press-fitting to the bottom wall 12 of the mating portion 12 of the housing 10, and is bent outward from the lower end of the fastening portion 31B. A curved portion 32B having a specific length, an elastic portion 33B bent down from the tip of the curved portion 32B to be parallel to the fastening portion 31B, a lead portion 34B extending downward from this elastic portion 33B, and a contact extending upward from the fastening portion 31Bunit35B. However, the length of the bent portion 32B is greater than the length of the bent portion 32A of the contact portion 30A; as a result, the lead portions of the contact portions 30A and 30B are staggered in the row arrangement direction of the contact members 30A and 30B. Each contact 30B is formed by punching and molding a metal plate. In each contact 30B, the flat surfaces of the fastening portion 31B, the elastic portion 33B, the lead portion 34B, and the contact portion 35B all extend in the row arrangement direction of the contact 30 (ie, the longitudinal direction of the housing 10). As shown in FIG. 2, the contact portion 35B is arranged at a specific pitch on the two side surfaces of the partition 15 through the two rows of contact pieces. As shown in FIG. 2, the curved portion 32B is used when the fastening portion 31B is joined to the mating The bottom wall of the portion 12 is positioned in the corresponding aperture portion 13 of the main body portion 11 of the housing 10. As shown in Figures 1(A) to 1(D), 2, 4(A), and 4(B), the elastic portion 33B is located in the orifice portion 13 and is formed in a substantially reverse S-shaped curve shape, so that The mating portion 12 can be elastically moved in the longitudinal direction of the housing 10 relative to the upper surface of the circuit board PCB and relative to the direction perpendicular to the longitudinal direction. Therefore, in the direction perpendicular to the longitudinal direction of the housing 10, due to the elastic portion 33B and the lead The portion 34B extends from the end of the bent portion 32B to the circuit board PCB with a relatively large length, so it is possible to make elastic movement. Furthermore, when the lead portion 34B passes through the alignment hole 24 of the toothed plate 20 (described later), the protrusion 36B that sits on the toothed plate 20 is formed on the side portion of the lead portion 34A.

The lead portions 34A and 34B of the contacts 30A and 30B are aligned by the toothed plate 20 and inserted into the through holes 60 in the circuit board PCB1 (FIG. 6 ). As shown in FIGS. 1(A) to 1(D) and 2, the toothed plate 20 is composed of a substantially rectangular plate extending in the same longitudinal direction as the housing 10, and is formed by molding an insulating resin. A number of alignment holes 24 are formed in the toothed plate 20 to allow the lead portions 34A and 34B of the contact members 30A and 30B to pass through to be aligned accordingly. Housing locking parts 21 that are locked on the main body part 11 of the housing 10 are formed, and these locking parts protrude from both ends of the upper surface of the toothed plate 20 with respect to the longitudinal direction. In addition, as shown most clearly in Figure 1(B), there are formed board locking portions 22 that are locked in the circuit board PCB1 when the floating connector 1 is mounted on the circuit board PCB1, and these board locking portions 22 are formed from Both ends of the lower surface of the toothed plate 20 protrude with respect to the longitudinal direction. In addition, at both ends of the lower surface of the toothed board 20, positioning rods 23 for positioning when the floating connector 1 is mounted on the circuit board PCB1 are formed on the inner side of the board locking portion 22 with respect to the longitudinal direction.

The method of manufacturing the floating connector 1 will be described below.

In the manufacturing process of the floating connector 1, the housing 10 and the toothed plate 20 are first molded and prepared.

At the same time, as shown in FIG. 3, many contact pieces 30A and 30B in a single row are punched out from the metal plate, wherein the positions of the elastic portions 33A and 33B are displaced along the axial direction of the contact pieces 30A and 30B, so that the adjacent contact pieces 30A It does not interfere with each other with 30B. In the state where these contacts are punched out from the metal plate, the adjacent contacts 30A and 30B are shared by the contact carrier C connected at the edges of the lead portions 34A and 34B. In such a bad state, not only the positions of the elastic parts 33A and 33B of the adjacent contact pieces 30A and 30B, but also the fastening parts 31A and 31B, the lead parts 34A and 34B, the protrusions 36A and 36B, and the contact part 35A The positions such as 35B and others are also displaced along the axial direction. Since the elastic parts 33A and 33B have a substantially inverted S-shape and a substantially S-shape, respectively, if the positions of these parts 33A and 33B are not displaced in the axial direction under the state of punching out the bad material of the contact piece, these parts will interfere with each other (assuming The arrangement pitch of the contact pieces 30A and 30B remains unchanged). Therefore, since the positions of the elastic portions 33A and 33B are displaced along the axial direction of the contact pieces 30A and 30B, the elastic portions 33A and 33B of the adjacent contact pieces 30A and 30B do not interfere with each other, thereby reducing the contact pieces on the contact piece plate. The arrangement pitch in the material, so that this kind of contact can obtain superiority in the use of contact material. In addition, since the elastic portions 33A having a substantially reverse S-shape and the elastic portions 33B having a substantially S-shape are alternately arranged, the diepin in the area between the elastic portions 33A and 33B can be strengthened, thereby facilitating contact Manufacturing of parts 30A and 30B.

In addition, after the multiple contact pieces 30A and 30B in a single row have been punched out from the metal plate, the contact pieces 30A and 30B are bent along the straight lines L1 and L2 shown in FIG. Curved portions 32A and 32B are formed between the elastic portions 33A and 33B, as shown in FIGS. 4(A) and 4(B). The length of the contact piece 30B between the straight lines L1 and L2 corresponds to the length of the curved portion 32B, and since the length of these curved portions 32B is greater than the length of the curved portion 32A, which is equivalent to the length of the contact piece 30A between the straight lines L1 and L2, The elastic portion 33B and the lead portion 34B are located more outside than the elastic portion 33A and the lead portion 34A, as shown in FIGS. 1(A) to 1(D), 2, 4(A) and 4(B), so that The plurality of contact members 30A and 30B in the form of a single row are arranged in a staggered configuration along the contact member arrangement direction.

In this way, since the multiple contact elements 30A and 30B in a single row form a staggered configuration along the contact element arrangement direction, it is possible to reduce the longitudinal direction of the housing 10 (ie the arrangement direction of the contact elements) and the direction perpendicular to the longitudinal direction (ie Perpendicular to the arrangement direction of the contact). Therefore, compact and high-density mounting on the circuit board PCB can be realized.

In addition, in a state where the contact carrier C connects the contacts 30A and 30B, all the multiple contacts 30A and 30B in a single row are inserted into the housing 10 at the same time. Since the planes of the lead portions 34A and 34B of the contact members 30A and 30B and the contact portions 35A and 35B extend along the arrangement direction of the contact member 30 (ie, the longitudinal direction of the housing 10), these contacts can all be inserted at the same time. Since all the contact pieces 30A and 30B can be inserted all at once, the fastening parts 31A and 31B of the contact pieces 30A and 30B are fastened to the bottom wall of the mating part 12 by press fitting. At the same time, since all the contacts 30A and 30B can be inserted into the housing 10 at the same time, a connector with high assembly efficiency can be obtained.

Then, by cutting along the dashed lines in FIGS. 4(A) and 4(B), the lead portions 34A and 34B of the contact members 30A and 30B are cut from the contact member carrier C. As a result, the fastening of the housing 10 by the contact members 30A and 30B of a row is completed.

After the contact pieces 30A and 30B of one row are fastened to the housing 10, the contact pieces 30A and 30B of the other row are fastened to the housing 10 in the same manner as described above.

Subsequently, the lead portions 34A and 34B of the contact members 30A and 30B pass through the alignment holes 24 of the toothed plate 20, and at the same time, the housing locking portion 21 of the toothed plate 20 is locked to the housing 10. So far, the floating connector 1 is completed.

As shown in Fig. 1(B) and Fig. 6, the floating connector 1 is mounted on the circuit board PCB1. In this case, the lead portions 34A and 34B of each contact 30A and 30B pass through the through hole 60 formed in the circuit board PCB1, and the positioning rod 23 of the toothed board 20 is inserted into the positioning hole (not shown) formed in the circuit board PCB1. ) To complete the horizontal positioning of the toothed board 20 relative to the circuit board PCB1; and then lock the board locking portion 22 onto the circuit board PCB1 to fasten the toothed board 20 to the circuit board PCB1. Then, the lead portions 34A and 34B are connected to the circuit board PCB1 by soldering.

When the floating connector 1 is mounted on the circuit board PCB1, manual or automatic mounting can be used. In the case of automatic installation, sometimes the positioning rod 23 and the plate locking portion 22 provided on the toothed plate 20 can be omitted, so that it is not necessary to form these components first. In this case, when the lead portions 34A and 34B of the contacts 30A and 30B pass through the through holes 60 formed in the circuit board PCB1, the portions of the lead portions 34A and 34B located below the circuit board PCB1 are bent, so that the toothed plate 20 and the circuit board PCB1 are clamped by the bent lead portions 34A and 34B and the protrusions 36A and 36B formed on the lead portions 34A and 34B, thus preventing the floating connector 1 from being separated from the circuit board PCB1.

When the mating connector 50 fastened to another circuit board PCB2 is mated with the mating portion 12 of the floating connector 1 after the floating connector 1 has been mounted on the circuit board PCB1, the contact members 30A and 30B The contact portions 35A and 35B and the elastic contact portion 55 of the mating contact 52 are in contact with each other, so that the two circuit boards are electrically connected to each other. In this case, since the elastic parts 33A and 33B can make the mating part 12 elastically move in the longitudinal direction of the housing 10 and in the direction perpendicular to the longitudinal direction, relative to the upper surface of the first circuit board PCB1, so as to absorb and fit the connection. The strain formed when the device 50 is mated.

In addition, in the manufacturing process of each contact 30A and 30B, since in addition to punching the metal plate, the processing only includes molding when forming the bent portions 32A and 32B, so the production efficiency of this contact is also good.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment but can have various other forms or variations.

For example, the bent portions 32A and 32B may be provided not only between the fastening portions 31A and 31B and the elastic portions 33A and 33B, but also between the elastic portions 33A and 33B and the lead portions 34A and 34B.

In the floating connector of claim 1, as described above, the plane of the elastic portion of the contact member extends along the row arrangement direction of the contact member, and the bent portion is provided between the fastening portion and the elastic portion or between the elastic portion and the elastic portion. Between the lead parts, the lead parts of the contact parts are arranged in a staggered configuration along the row arrangement direction of the contact parts. Therefore, the area occupied by the row arrangement direction and the row arrangement direction of the contacts can be reduced, so that compact and high-density mounting on the circuit board can be realized. In addition, all the contacts can be inserted into the housing at the same time, making this connector superior in terms of assembly efficiency. In addition, since only one molding is required in the forming of the bent portion, the contact piece has good production efficiency.

The floating connector of claim 2 moves the position of the elastic part in the invention of claim 1 so that the elastic parts of adjacent contact members do not interfere with each other when the plurality of contact members are punched out. In this way, the pitch of the node arrangement in the sheet material used for the contact can be reduced, thereby providing a floating connector with superiority in saving materials.

The method for manufacturing a floating connector of claim 3 includes the steps of: punching out a plurality of contact pieces arranged in a single row, wherein each contact piece has a fastening portion fastened to the housing and a contact piece contacting the corresponding mating contact piece. The contact part, the lead part connected to the circuit board, and the curved elastic part provided between the fastening part and the lead part, and the position of these elastic parts is displaced along the axial direction of the contact to make the adjacent contact elastic The parts do not interfere with each other; a bent part is provided between the fastening part and the elastic part or between the elastic part and the lead part, so that the lead parts of the plurality of contacts are arranged in a staggered configuration; take the plurality of lines in one row The arranged contact pieces are inserted into the housing at the same time; then the tip of the lead part of each contact piece is cut off from the contact piece carrier. As a result, a connector can be manufactured in which contacts that are superior in terms of saving contact materials can be inserted at the same time, so that the assembly efficiency of the connector can be improved and compact and high-density installation can be realized.
