The top wall 18 and bottom wall 20 of the frame 14 have an opening 42 for interlocking the mounting plate 12 with the frame 14, as described in more detail below. The top wall 18 and bottom wall 20 also have flange portions 44 to guide and support the mounting plate 12 with respect to the frame 14 on opposite sides.
FIG. 1 shows a panel with a frame for accommodating two rows of mounting plates 12, while FIG. 5 shows an alternative panel 110 with a frame 114 for accommodating a single row of mounting plates 12. .. Panel 110 is similar in structure and function to panel 10.
As shown in FIGS. 3 and 4, the mounting plates 12 can be assembled in a vertical arrangement. As shown in FIG. 6, the mounting plates 12 can be assembled in a horizontal arrangement. The mounting plate 12 has a top wall 46, a bottom wall 48, a first side wall 50, a second side wall 52, an open front end 54, and an open rear end 55. The mounting plate 12 has an elongated flange 56 defined on the outer surface 58 of the top wall 46. Each mounting plate 12 also has an elongated groove 60 defined on the outer surface 62 of the bottom wall 48, which is configured to slidably fit into the top flange 56 of the mounting plate 12. Each mounting plate 12 also has an elongated flange 64 on the outer surface 66 of the first side wall 50 and an elongated groove 68 on the outer surface 70 of the second side wall 52. The side flange 64 and the groove 68 are configured to be slidably fitted. In this way, the two mounting plates 12 can be slidably coupled together in the vertical arrangement as shown in FIGS. 1 to 4 and in the horizontal arrangement as shown in FIGS. 5 and 6. The elongated flanges 56, 64 and the grooves 60, 68 have a doweltail-shaped contour that cannot be separated in the direction perpendicular to the sliding direction when the two mounting plates 12 are slidably joined together.
Each mounting plate 12 also has a structure for interlocking the mounting plate 12 with the frame 14, as described above. As shown in FIGS. 1-8, the two outermost flanges 56 on the top wall 46 of each mounting plate 12 have a tab 70 with a lamp adjacent to the dorsal 72 of the flange 56. Also, as shown in FIG. 8, the bottom wall 48 of each mounting plate 12 defines a pair of lamped tabs 74 on the sides of the central groove 60. The tab 70 with top lamp and the tab 74 with bottom lamp are configured to connect the mounting plate 12 to the frame 14 by snapping inside the openings 42 in the top wall 18 and bottom wall 20 of the frame 14. .. One of the tabs 70 with lamps and one of the openings 42 on the frame 14 are depicted in a magnified view in Figure 2. The tab 70 with the top lamp and the tab 74 with the bottom lamp of the mounting plate 12, and the top opening and the bottom opening 42 of the frame 14 attach the front opening 26 of the frame 14 to the mounting plate 12. Aligned with 28 cable connection locations 30.
As shown in FIG. 8, the two outermost elongated grooves 60 defined on the bottom wall 48 of the mounting plate 12 are tabs with a top lamp on another mounting plate 12 when the two mounting plates 12 are vertically joined. It has a deeper elongated slot 76 inside the groove 60 to accommodate the 70. Each mounting plate 12 also has shorter slots 78 provided on each side of the central top flange 56 to accommodate the lamped tabs 74 defined on the bottom wall 48 of the mounting plates 12, as shown in FIGS. have. Since the side walls 50 and 52 of the mounting plate 12 do not include a snap-on structure for creating an interlock with the frame 14, the side walls 50 and 52 of the mounting plate 12 include a structure for accommodating tabs with lamps. Absent.
In the illustrated embodiment, the mounting plate 12 is mounted from the rear end 55 of the upper mounting plate 12 to the front end 54 of the lower mounting plate 12 by a deeper elongated slot 76 on the bottom wall 48 and a shorter slot 78 on the top wall 46. It can be slidably coupled to the upper side of another mounting plate 12 in the direction toward, and can only be removed in the opposite direction. Further, in the illustrated embodiment, the lower mounting plate 12 can be removed in the direction from the rear end 55 of the upper mounting plate 12 toward the front end 54 of the lower mounting plate 12, and can only be connected in the opposite direction. The rear end 80 of the deeper elongated slot 76 acts as a stopper for the lower mounting plate 12 by abutting the vertical surface 82 of the tab 70 with top lamp when the two mounting plates 12 are joined together in the vertical direction. When connecting three or more mounting plates 12 in the vertical direction, follow the same orientation.
As shown in FIGS. 7 and 8, the mounting plate 12 is used to mount the coaxial switching jack 28 to the frame 14. The mounting plate 12 and the coaxial switching jack 28 have a fitting structure and an interlock structure for mounting the coaxial switching jack 28 to the mounting plate 12. As shown in FIGS. 7-10, each of the coaxial switching jacks 28 has a pair of vertical guides 84 extending from the front wall 86 of the jack 28 toward the back wall 34 of the jack 28, and one guide 84. Is located on the top wall 88 of Jack 28, and the other guide is located on the bottom wall 90 of Jack 28. The top guide 84 of the jack 28 has a nearly rectangular contour, while the guide 84 on the bottom wall 90 has a dovetail contour. The top guide 84 of the jack 28 slides in the slot 92 on the inner surface 94 of the top wall 46 of the mounting plate 12. The bottom guide 84 of the jack 28 slides in a doweltail-shaped slot 96 on the inner surface 98 of the bottom wall 48 of the mounting plate 12.
Each jack 28 also has a flexible cantilever arm 100 with a tab 102 with a ramp for snapping the jack 28 onto the mounting plate 12. The cantilever arm 100 extends from a rectangular guide 84 on the top wall 88 of the jack 28 toward the back wall 34 of the jack 28. The lamped tab 102 of the flexible cantilever arm 100 snaps into the opening 104 defined in the top wall 46 of the mounting plate 12.
The back wall 34 of the jack 28 defines a flange 106 that extends downward. The dowel tail guide 84 on the bottom wall 90 extends from the front wall 86 of the jack 28 to the flange 106 extending downward. When the jack 28 is slidably inserted into the mounting plate 12, the flange 106 abuts against the bottom wall 48 of the mounting plate 12. Further downward from the flange 106 is the grip tab 108. The grip tab 108 is formed as part of the back wall 34 of the jack 28. The grip tab 108 preferably allows the user to reliably grip the jack 28 and apply opposing forces to the cantilever arm 100 and the grip tab 108 to slide it relative to the mounting plate 12. In addition, it is located on the jack 28 facing the cantilever arm 100.
When the jack 28 is mounted in the mounting plate 12, the jack 28 can slide forward with the guide 84 fitted in the slots 92 and 96. The jack 28 can slide forward until the cantilever arm 100 bends downwards, the tab 102 with lamps passes under the top wall 46 of the mounting plate 12, and is inserted into the opening 104. When you want to remove the jack 28 from the mounting plate 12, you can push down the cantilever arm 100 by applying opposing forces to the cantilever arm 100 and the grip tab 108. As the cantilever arm 100 bends downwards, the tab 102 with lamps separates from the opening 104 of the mounting plate 12 and the jack 28 slides rearward.
The matching and interlocking structures between the jack 28 and the mounting plate 12 shown, between the two mounting plates 12, and between the mounting plate 12 and the frame 14 are non-limiting examples, and other configurations are possible. Please note that. For example, in another embodiment, the slots 92, 96 and the vertical guides 84 of the jack 28 on the inner surfaces 94, 98 of the top wall 46 and bottom wall 48 of the mounting plate 12 may be swapped.
Explaining FIGS. 9 to 19, the coaxial switching jack 28 has a housing 116 with a cover 118. In some embodiments, the housing 116 defines the non-conductor 120. Housing 116 defines a front wall 86, a back wall 34, a top wall 88, a bottom wall 90, and a side wall 122 located opposite the cover 118.
Jack 28 defines a pair of rear cable connection locations 36 and a pair of front cable connection locations 30. The rear cable connection location 36 is configured as a pair of rear openings 40 defined in the back wall 34 of the housing 116. The front cable connection location 30 is configured as a pair of front openings 32 in the front wall 86 of the housing 116. As mentioned above, the longitudinal guide 84 is located on the top wall 88 and bottom wall 90 of the housing 116, on which the flexible cantilever arm 100 is located.
The housing 116 and the cover 118 work together to define the interior 124. The interior 124 of the housing 116 is shaped to accommodate the various components of the jack 28. The interior 124 can be approached through the back opening 40 or the front opening 32. Components mounted within the interior 124 can be inserted into the housing 116 through a side opening 126 that is closed by the housing 116. The cover 118 has fastener holes 128 for fastening the cover 118 to the housing 116 with fasteners 130. The cover 118 also has an opening 132 for accommodating the resistor assembly 134, as described further below. The cover 118 has a mark 136 indicating the position of the resistor 140 inside the housing 116.
Included in the back wall 34 of the housing 116 is a slot 142 for receiving the name label panel 144. The designated label panel 144 is slidably inserted into the slot 142, where it is held by friction fit. Slot 142 has an upper notch 146 that facilitates removal of the labeled label panel 144 from the back wall 34 of housing 116.
Explaining FIGS. 15, 16 and 19, inside the interior 124 is a central conductor contact spring 148 and a pair of isomorphic outer shell conductor contact springs 150. Also, a resistor assembly 134 is mounted inside the internal 124, which is located between a pair of coaxial assemblies 152. Each coaxial assembly 152 has a center conductor 154 and an outer shell conductor 156. The center conductor contact spring 148 is mounted such that the arm 158 of the center conductor contact spring 148 is normally in contact with the center conductor 154 of the coaxial assembly 152. The outer shell conductor contact springs 150 are normally mounted so that they are in electrical contact with each other and with the outer shell conductor 156 of the coaxial assembly 152. The springs 148, 150 are preferably made of an elastic conductive material. The non-conductive material of the housing body 120 electrically insulates the outer shell conductor 156 of the coaxial assembly 152.
As shown in FIGS. 16 and 19, the center conductor contact spring 148 is located inside the housing 116 between the bulkhead 160 and the front wall 86. The arm 158 of the spring 148 extends outward so that it is in electrical contact with the center conductor 154 of the coaxial assembly 152. Attached adjacent to the outer end 162 of each arm 158 is an insulator contact pad 164. With the connector 38 not inserted through the front opening 32, the spring 148 typically electrically connects the center conductor 154. When in the normal position, i.e., in the unswitched position, the pad 164 does not physically contact the coaxial assembly 152 as shown in FIG. 19 when the connector 38 is not inserted through the front opening 32. However, when the cable connector 38 is inserted through the front opening 32, the contact pad 164 makes first contact with the cable connector 38, as described in more detail below, and electricals the coaxial assembly 152 from the rest of the circuitry inside the jack 28. Insulate.
To further illustrate FIGS. 16 and 19, the resistor assembly 134 is located between the two outer shell conductor contact springs 150. As further detailed, the resistor assembly 134 can be switched between the "on" or "terminating" position 166 and the "off" or "non-terminating" position 168. When the resistor assembly 134 is turned to the "on" position 166, the resistor 140 provides an electrical connection between the outer shell conductor contact springs 150 to terminate one of the coaxial assemblies 152. The resistor assembly 134 can be turned to the "off" position 168 to electrically insulate the two outer shell conductor contact springs 150 from each other.
21 and 22 show the coaxial assembly 152 of the jack 28. Each coaxial assembly 152 has a central conductor 154 that is electrically insulated from the outer shell conductor 156 by an insulating spacer 170. The spacer 170 coaxially positions the center conductor 154 within the outer shell conductor 156 and insulates the center conductor 154 from the outer shell conductor 156. The outer shell conductor 156 defines three different portions extending between the front end 172, the rear end 174, and the front end 172 and the rear end 174. The first portion 176 is adjacent to the rear end 174 and has a flat portion 178. The outer shell conductor 156 defines an intermediate second portion 180 having a diameter smaller than that of the first portion 176. The first portion 176 and the second portion 180 form a nearly circular flange 182 between each other. The outer shell conductor 156 defines a third portion 184 adjacent to the front end 172. The third portion 184 is a portion that receives the cable connector and has a vertically extending leg 186 with a slot 188 defined between them, and the leg 186 has a radius to receive the cable connector 38. It is configured to bend in the direction. The third portion 184 has a diameter smaller than that of the intermediate portion 180 and forms a substantially circular flange 190 with the intermediate portion 180. A third portion 184 of the outer shell conductor 156 defines an opening 192 around it 194. The opening 192 is approximately inwardly facing the center of the interior 124 of the housing 116 when the coaxial assembly 152 is seated in the housing 116. Through this opening 192, as shown in FIG. 19, the arm 158 of the center conductor contact spring 148 extends into the coaxial assembly 152, which allows electrical connection with the center conductor 154.
As shown in FIG. 15, the inner surface 196 of the cover 118 has a shape complementary to the shape of the outer shell conductor 156. Similarly, the interior 124 of the housing 116 has a shape complementary to the shape of the outer shell conductor 156. The housing 116 and cover 118 have a flat portion 198 that is complementary to a flat portion 178 defined in the first portion 176 of the outer shell conductor 156. The flat portion 198 of the housing 116 and the cover 118 and the flat portion 178 of the outer shell conductor 156 serve to prevent the outer shell conductor 156 once seated in the housing 116 from turning in the radial direction. This allows the opening 192 to be properly aligned with respect to the arm 158 of the center conductor contact spring 148. The housing 116 and cover 118 also have shoulderers 200, 202 that abut against the flanges 182, 190 and serve to prevent the coaxial assembly 152 from moving longitudinally inside the housing 116, respectively. The illustrated coaxial assembly embodiment is one non-limiting example, and the internal shape and cover 118 of the coaxial assembly and housing 116 can take various other forms within the framework of the gist of the present invention. I want you to understand.
22 and 23 show the resistor assembly 134 of the present invention. The resistor assembly 134 has a resistor 140 housed inside an insulating resistor housing 204. The resistor housing 204 has a bottom 206 with a pair of flexible legs 208 that receive and hold the resistor 140 between them. The resistor housing 204 has a top 210 with two flanges 212 defining a slot 214 between it. Once inserted inside the jack housing 116, the resistor housing 204 can rotate around its own vertical axis A. Slots 214 defined between the flanges 212 at the top 210 of the resistor housing 204 can be used to rotate the resistor housing 204. In the illustrated embodiment, the resistor housing 204 can rotate to either provide 75 ohm resistance between the outer shell conductor contact springs 150 or to electrically insulate the outer shell conductor contact springs 150 from each other. In other embodiments, resistors with other resistance values can be used. The resistor 140 can be removed from the resistor housing 204 and replaced with another resistor if necessary. The resistor 140 can be replaced by removing it from the jack 28 and first removing the resistor housing 204.
The bottom 206 of the resistor housing 204 has a first set of recesses 216 and a second set of recesses 215. The recesses 215, 216 are located around the bottom 206 of the resistor housing 204 at approximately 90 degree spacing. The recess 216 is defined as part of the flexible leg 208. The recess 215 both has a portion that is part of the flexible leg 208 and a portion that is defined between the flexible legs 208. The recesses 215 and 216 are configured to house the bends of the outer shell conductor contact spring 150 when the resistor housing 204 is turned to the "on" position 166 or the "off" position 168 (see FIG. 19). reference). The outer shell conductor contact spring 150 applies spring tension to the edges 217 and 219 of the recesses 215 and 216, respectively, and the edges 217 and 219 of the recesses 215 and 216 hit the outer shell conductor contact springs 150, respectively, resulting in a resistor. When the 140 is turned to the "on" position 166 or the "off" position 168, the resistor 140 will be held in that position.
24 and 25 show the jack 28 with the cable connector 38 inserted into one of the front openings 32. In this arrangement, the outer conductor 218 of the cable connector 38 is electrically connected to the outer shell conductor 156 and the center conductor 220 of the cable connector 38 is electrically connected to the center conductor 154 of the coaxial assembly 152. When the connector 38 is inserted into the opening 32, the front end 222 of the connector 38 first contacts the insulating pad 164 of the center conductor contact spring arm 158. When not in contact with the spring 148, the front end 222 deflects the arm 158 away from contact with the center conductor 154. This breaks the electrical coupling between the center conductors 154 of the coaxial assembly 152. The pad 164 insulates the outer conductor 218 of the cable connector 38 from electrical contact with the spring 148.
As shown in FIG. 25, after the arm 158 has moved away from contact with the center conductor 154, the arm 158 pushes the first end 224 of the outer shell conductor contact spring 150 and the opposite second end. The 226 is deflected away from the other outer shell conductor contact spring 150, breaking the direct electrical contact between the two outer shell conductor contact springs 150. Thus, the mating coaxial assembly 152 to which the cable connector 38 is coupled is completely electrically isolated from the other coaxial assembly 152 inside the jack 28. With the movement of the springs 148, 150, the center conductor 154 of the coaxial assembly 152 becomes electrically connected to the outer shell conductor 156 of the other coaxial assembly 152 through the resistor 140.
When the cable connector 38 is inserted into the front opening 32, the outer conductor 218 of the connector 38 closes the opening 192 around the outer shell conductor 156 of the coaxial assembly 152. Thus, the outer shell conductor 218 of the connector 38 and the outer shell conductor 156 of the corresponding coaxial assembly 152 work together to form a nearly cylindrical conductivity centered on the central conductor 220 of the connector 38 and the corresponding central conductor 154 of the coaxial assembly 152. Form passage 228. This cylindrical passage 228 extends from the front opening 32 to the back opening 40.
Now, as shown in FIGS. 24 and 25, when one connector 38 is inserted through the opening 32 and inside one coaxial assembly 152, the other coaxial assembly 152 is in electrical contact with the springs 148 and 150. Stay in a state. Through the resistor 140, the springs 148 and 150 now electrically connect the center conductor 154 and the outer shell conductor 156 of the other coaxial assembly 152. In some cases, it is desirable to have some level of impedance between the center conductor 154 and the outer shell conductor 156, for example about 75 ohms. In such cases, the resistor 140 may be expected to be in the "on" position or the "termination" position 166, as shown in FIG. Other levels of impedance may also be expected by replacing the resistor 140 with another resistor inside the resistor housing 204.
Alternatively, it may be desirable to electrically insulate the center conductor 154 of the unconnected coaxial assembly 152 from the outer shell conductor 156. In such cases, the resistor assembly 134 can be turned or rotated to the "off" or "non-terminated" position 168 as shown in FIG. When in this position, the insulating flange 212 located at the top 210 of the resistor housing 204 electrically insulates the two outer shell conductor contact springs 150 from each other.
As shown in FIG. 26, when the second cable connector 38 is inserted into the other front opening 32, the front end 222 of the second connector 38 deflects the arm 158 away from the center conductor 154. The arm 158 pushes the first end 224 of the outer shell conductor contact spring 150 and bends the second end 226 away from direct electrical contact with the other outer shell conductor contact spring 150. Thus, when the two cable connectors 38 are inserted into the front opening 32 of the coaxial switching jack 28, the center conductor contact spring 148 and the outer shell conductor contact spring 150 are such that the two coaxial assemblies 152 are electrically insulated from each other. Be directed in the direction.
FIGS. 29 to 32 show alternative embodiments of the coaxial jack 300 according to the present invention. The structure of the jack 300 is similar to that of the jack 28 in FIGS. 9 to 19. However, the jack 300 is configured as a direct non-switchable jack. Therefore, in this embodiment, the jack housing 302 does not include the springs 148 and 150 described above. When the connector 38 is inserted into the front opening 304 as in the embodiment of the switching jack 28, the outer shell conductor 218 of the connector 38 and the outer shell conductor 306 of the corresponding coaxial assembly 308 work together to form the central conductor of the connector 38. A nearly cylindrical conductive passage 310 is formed centered on the central conductor 312 of the coaxial assembly 308 corresponding to 220.
The coaxial jack 300 of FIGS. 29-32 does not include the resistor assembly 134. In FIG. 29, the jack housing 302 is depicted with the cover 314 mounted on top. As depicted, cover 314 does not include any structure that houses the rotatable resistor assembly 134, as in the first embodiment of coaxial jack 28.
Earlier, we explained that the housing 116 of the switchable coaxial jack 28 has a non-conductive material 120, but it should be noted that certain parts of the housing 116 may contain conductive material. For example, in certain embodiments, parts of housing 116 may contain conductive material for harmonization purposes. By providing a specific amount of conductive material on the inner 124 of the housing 116 or on the outer periphery of the housing 116, the impedance level between the central conductor 154 and the outer shell conductor 156 can be adjusted and tuned to the desired value.
In another embodiment, regardless of whether the jack is a switchable jack 28 or a direct jack 300, certain parts of the housing are for shielding purposes to prevent crosstalk between adjacent jacks. May contain a conductive material. For example, in certain embodiments, conductive shielding may be provided on the surface of the cover and / or on the surface of the opposite jack sidewall. In other embodiments, the shielding portion can be provided on the surface of the other housing portion.
