Description

Technical Field

[0001] This invention relates to a connector, and more particularly to a connector assembly. Background Technology

[0002] Chinese Invention Patent Publication No. CN101669256B (corresponding US Patent No. US7,845,975 B2) discloses a connector assembly. The cage element of the connector assembly has multiple alignment features on its sidewall, and the connector housing has multiple alignment slots on its sidewall. The corresponding alignment features on the sidewall of the cage element align with the slots on the sidewall of the connector housing, ensuring proper alignment between the cage element and the connector housing. However, the alignment features disclosed in this patent are pieces cut from the sidewall of the cage element, and these pieces extend approximately perpendicular to the body of the sidewall. Therefore, the alignment features constructed from these pieces have low strength and are easily deformed. Summary of the Invention

[0003] Therefore, one object of the present invention is to provide a connector assembly that can improve upon at least one of the disadvantages of the prior art.

[0004] Therefore, in some embodiments of the connector assembly of the present invention, a shielding cover, a receptacle connector, and a rear cover are included. The shielding cover includes a mating channel having a rear opening, and a top wall, two side walls, and a bottom wall defining the mating channel. Each side wall has an integrally formed stop that protrudes toward the mating channel. The stop is a three-dimensional convex structure with an upper flange and a rear flange. The bottom wall has a rearwardly extending insert. The socket connector is disposed at the rear end of the insertion channel of the shielding cover through the rear opening. The socket connector includes a socket housing with a stop receiving groove integrally formed on the side and a slot integrally formed on the bottom with an opening facing forward. The stop receiving groove accommodates the stop blocks on the side walls and has an upper channel inner edge and a rear channel inner edge. The upper channel inner edge is stopped by the upper flange of the corresponding stop block, and the rear channel inner edge is stopped by the rear flange of the corresponding stop block. The insert of the shielding cover is inserted rearward into the slot. The rear cover is assembled to the rear opening of the shielding cover.

[0005] In some embodiments, the bottom wall of the shield also has an integrally constructed rearwardly extending support plate located on both sides of the insert and extending beyond the end of the insert, the support plate being used to support the bottom of the socket housing.

[0006] In some embodiments, the insert is positioned above the support plate.

[0007] In some embodiments, the front and lower edges of each sidewall block are integrally connected to the body of the sidewall, and the upper and rear edges of the block are cut out from the body of the sidewall and separated from the body of the sidewall inward to form the upper flange and the rear flange, respectively.

[0008] In some embodiments, the back cover has an integrally formed pressure spring that presses forward against the rear end of the socket housing.

[0009] In some embodiments, each of the sidewalls also has an anti-reverse stop plate integrally formed behind the stop block, the anti-reverse stop plate blocking the rear end of the socket housing to prevent the socket connector from moving backward.

[0010] In some embodiments, the rear edge of the anti-reverse stop is integrally connected to the body of the corresponding sidewall, and the anti-reverse stop extends obliquely forward and inward, with the front edge of the anti-reverse stop abutting against the rear end of the socket housing.

[0011] In some embodiments, the shielding cover includes an upper housing and a lower housing assembled together to form the insertion channel, the upper housing having a top wall and side walls integrally connected to each other and defining the insertion channel, and the lower housing having a bottom wall defining the insertion channel.

[0012] In some embodiments, the shield includes two insertion channels arranged vertically. The shield includes an upper housing, a lower housing, and a partition frame assembled together to form the two insertion channels. The upper housing has a top wall and the side walls integrally connected to each other, and the lower housing has a bottom wall. The two insertion channels are defined by the top wall, the side walls, and the bottom wall and separated by the partition frame.

[0013] The stop block in this invention has a three-dimensional convex structure, resulting in high strength and resistance to deformation. It guides the socket connector into the shield during assembly. Furthermore, the upper edge of the stop block prevents the socket connector from moving downwards relative to the shield, while the rear edge prevents it from moving forwards. Secondly, since the inserts on the bottom wall of the shield are inserted into the slots at the bottom of the socket housing, and the support plate on the bottom wall of the shield supports the bottom of the socket housing, the assembly strength between the socket connector and the shield is enhanced. Furthermore, by applying forward pressure to the pressure spring on the rear cover at the rear end of the socket housing, the rearward movement of the socket connector is prevented, and its assembly position is fixed. Additionally, the anti-reverse stop on the side wall of the shield at the rear end of the socket housing further prevents the socket connector from moving backwards. In summary, the above structure increases the assembly strength and integrity between the socket connector and the shield, improving both resistance to external forces and the accuracy of the assembly position.

[0100] Before the invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0101] See Figures 1 to 3 A first embodiment of the connector assembly 100 of the present invention is adapted to be plugged into a pluggable module 200. The pluggable module 200 includes a housing 201, a plug plate 202, and a cable 203. The housing 201 includes a plug portion 201a, the plug plate 202 is disposed at the end of the plug portion 201a, and the plug plate 202 has a plurality of contact fingers 202a. The cable 203 is disposed in the housing 201 and is mechanically and electrically connected to the plug plate 202. The connector assembly 100 includes a shielding cover 1, a socket connector 2, and a rear cover 3.

[0102] The shielding cover 1 is constructed, for example, by stamping and bending a conductive metal plate, and is used to guide the pluggable module 200 and to shield against electromagnetic interference. The shielding cover 1 extends along a front-to-back direction D1 (arrow indicates front, reverse indicates rear) and includes a plug-in channel 11, a top wall 12, two side walls 13 spaced apart and connected to both sides of the top wall 12 along a left-to-right direction D2 (arrow indicates right, reverse indicates left), and a bottom wall 14 spaced apart and connected to the bottom edge of the two side walls 13 along a vertical direction D3 (arrow indicates up, reverse indicates down). Furthermore, the plug-in channel 11 is defined by the top wall 12, the two side walls 13, and the bottom wall 14. The plug-in channel 11 has a front socket 111 for the pluggable module 200 to be inserted at the front end, and a rear opening 112 at the rear end.

[0103] In this first embodiment, the shield 1 includes an upper housing 15 and a lower housing 16 assembled together to form the insertion channel 11. The upper housing 15 has a top wall 12 and two side walls 13 integrally connected to each other and defining the insertion channel 11. The lower housing 16 has a bottom wall 14 defining the insertion channel 11. The lower housing 16 of the shield 1 is assembled to the two side walls 13 of the upper housing 15. A recess 131 is formed at the bottom edge near the front end of each side wall 13 of the upper housing 15, and a plurality of fasteners 132 and a downward-facing insertion hole 133 are formed on each side wall 13. The bottom wall 14 of the lower housing 16 integrally forms two protrusions 141 corresponding to the recesses 131 of the two side walls 13, and two side plates 142 corresponding to the outer sides of the two side walls 13. The recesses 131 and the protrusions 141 form a dovetail structure. Each side plate 142 is formed with a plurality of snap holes 142a that engage with the snap blocks 132 of the corresponding side wall 13, and an insertion portion 142b that is inserted into the insertion hole 133 of the corresponding side wall 13, thereby enabling the bottom wall 14 of the lower housing 16 to be assembled and joined to the two side walls 13 of the upper housing 15.

[0104] See Figures 1 to 5The socket connector 2 is disposed at the rear end of the insertion channel 11 of the shield 1 through the rear opening 112. The socket connector 2 includes a socket housing 21, a plurality of terminals 22, and a plurality of cables 23. The socket housing 21 has a forward-facing insertion groove 210, and the plurality of terminals 22 are disposed in the socket housing 21 and extend into the insertion groove 210. In this first embodiment, the socket connector 2 further includes a plurality of terminal fixing blocks 25 that partially cover the plurality of terminals 22 and are disposed within the socket housing 21. The tails of the plurality of terminals 22 of the terminal fixing blocks 25 located in the middle and having a vertical structure extend from the bottom of the socket housing 21, and the tails of the plurality of terminals 22 of the terminal fixing blocks 25 located on the left and right sides and having a horizontal structure are respectively connected to the plurality of cables 23, and the plurality of cables 23 extend from the rear end of the socket housing 21.

[0105] See Figures 3 to 7 Each sidewall 13 has an integrally formed stop 134 protruding toward the insertion channel 11. The stop 134 is a three-dimensional convex structure with an upper stop 134a and a rear stop 134b. Specifically, the front and lower edges of the stop 134 of each sidewall 13 are integrally connected to the body of the sidewall 13. The upper and rear edges of the stop 134 are cut out from the body of the sidewall 13 and separated from the body of the sidewall 13 inward to form the upper stop 134a and the rear stop 134b, respectively. The bottom wall 14 has a rearwardly extending insert 143 and two integrally formed rearwardly extending support plates 144 located on both sides of the insert 143 and extending beyond the end of the insert 143. Specifically, the insert 143 is located above the support plates 144.

[0106] The socket housing 21 has two block receiving grooves 211 integrally formed on the side and a slot 212 integrally formed on the bottom with its opening facing forward. The block receiving grooves 211 accommodate the blocks 134 of the two side walls 13. The block receiving grooves 211 have an upper channel inner edge 211a and a rear channel inner edge 211b. The upper channel inner edge 211a is blocked by the upper edge 134a of the corresponding block 134, and the rear channel inner edge 211b is blocked by the rear edge 134b of the corresponding block 134. The insert 143 of the shielding cover 1 is inserted rearward into the slot 212, and the support plate 144 is supported on the bottom of the socket housing 21. Further, in this first embodiment, the insert 143 has an interference protrusion 143a that interferes with and is fixed to the slot 212, and the bottom of the socket housing 21 has two receiving recesses 213 integrally formed to accommodate the two support plates 144.

[0107] See Figure 1and Figures 3 to 6 Because the stop 134 has a three-dimensional convex structure, its overall structural strength is high and it is not easily deformed. Furthermore, it guides the socket connector 2 into the shielding cover 1 during assembly. Additionally, the upper flange 134a of the stop 134 prevents the socket connector 2 from moving downwards relative to the shielding cover 1, while the rear flange 134b of the stop 134 prevents the socket connector 2 from moving forward relative to the shielding cover 1. Secondly, because the insert 143 of the bottom wall 14 of the shielding cover 1 is inserted into the slot 212 at the bottom of the socket housing 21, and the support plate 144 of the bottom wall 14 of the shielding cover 1 is supported at the bottom of the socket housing 21, the assembly strength between the socket connector 2 and the shielding cover 1 is enhanced.

[0108] See Figures 1 to 4 and Figure 8 The rear cover 3 is assembled to the rear opening 112 of the shielding cover 1. Each side wall 13 of the shielding cover 1 also has a plurality of fastening tabs 135 extending rearward from the rear edge. The rear cover 3 has two side fastening tabs 31 extending forward from the left and right sides to overlap the side walls 13 of the shielding cover 1, a plurality of upper fastening tabs 32 extending forward from the upper edge to overlap the top wall 12 of the shielding cover 1, and a plurality of fastening holes 33 formed at the connection between the side fastening tabs 31 and the body of the rear cover 3. The plurality of fastening tabs 135 of the shielding cover 1 pass through the plurality of fastening holes 33 and then bend inward. In detail, in this first embodiment, the side fastening tabs 31 of the rear cover 3 extend forward and inward at an inward angle and have their ends folded outward. The side fastening tabs 31 are pressed inward against the side walls 13 of the shielding cover 1 with a positive force. In addition, the plurality of cables 23 of the socket connector 2 extend rearward through the rear cover 3.

[0109] The rear cover 3 has an integrally formed pressure spring 34 that presses forward against the rear end of the socket housing 21. As described above, the rear edge 134b of the stop 134 abuts against the rear inner edge 211b of the stop receiving groove 211 to prevent the socket connector 2 from moving forward, while the pressure spring 34 prevents the socket connector 2 from moving backward. Therefore, the pressure spring 34 can provide a forward engagement force to position the socket connector 2 relative to the shield 1. In addition, in this first embodiment, the pressure spring 34 has a downwardly and forwardly extending elastic piece 341. By pressing forward against the pressure spring 34 of the rear cover 3 at the rear end of the socket housing 21, the rearward movement of the socket connector 2 can be prevented and the assembly position of the socket connector 2 can be positioned. The combined structure of the stop block 134, the stop block receiving groove 211, the insert 143, the slot 212, the support plate 144, and the pressure spring 34 increases the assembly strength and integrity between the socket connector 2 and the shield 1, improving not only the resistance to external forces but also the accuracy of the assembly position.

[0110] Furthermore, in this first embodiment, the connector assembly 100 also includes two metal shielding members 4 configured in a tree-like structure and sandwiched between the socket housing 21 and the rear cover 3. Each metal shielding member 4 has a vertically extending trunk 41 and a plurality of elastic arms 42 extending horizontally from the trunk 41. The metal shielding member 4 is located at the rear end of the socket housing 21. The trunk 41 and the plurality of elastic arms 42 are respectively located between each cable 23 to provide electromagnetic shielding between the plurality of cables 23. When not under stress, the plurality of elastic arms 42 are tilted backward at a small angle, thereby reliably pressing backward against the rear cover 3, which is also made of metal, and thus electrically connecting with each other to achieve grounding.

[0111] See Figure 1 and Figure 3After the pluggable module 200 enters the insertion channel 11 of the shield 1 through the front insertion port 111, the insertion plate 202 at the end of the insertion part 201a of the pluggable module 200 can be inserted into the insertion slot 210 of the socket connector 2, so that the contact finger 202a of the insertion plate 202 contacts the terminal 22 in the insertion slot 210 of the socket connector 2, so that the pluggable module 200 and the socket connector 2 of the connector assembly 100 mate with each other. Furthermore, the front section of the shield 1, near the front connector 111, can be provided with a mounting hole in a housing (not shown). The shield 1 also includes a plurality of grounding members 17 provided at the front connector 111. Each grounding member 17 has a plurality of elastic fingers 171 extending rearward from the front connector 111 and distributed on the outer and inner sides. The outer elastic fingers 171 are used to partially contact the periphery of the mounting hole in the housing, and the inner elastic fingers 171 are used to contact the housing 201 of the pluggable module 200.

[0112] See Figures 9 to 12 A second embodiment of the connector assembly 100 of the present invention differs from the first embodiment in that the shielding cover 1 includes two vertically arranged insertion channels 11. The shielding cover 1 includes an upper housing 15, a lower housing 16, and a partition frame 18 assembled together to form the two insertion channels 11. The partition frame 18 has an upper plate 181 and a lower plate 182 spaced apart vertically, two side connecting plates 183 connected between the upper plate 181 and the lower plate 182 and spaced apart horizontally, a front connecting plate 184 connected between the upper plate 181 and the lower plate 182 and located at the front end, and a plurality of fixing tabs 185 formed on the side edges of the upper plate 181 and the lower plate 182. Each side wall 13 of the shielding cover 1 also has a plurality of fixing through holes 136 corresponding to and cooperating with the plurality of fixing tabs 185. Multiple fixing flaps 185 are bent after passing through multiple fixing perforations 136 so that the compartment frame 18 is assembled to the two side walls 13 of the shield 1.

[0113] The upper housing 15 has a top wall 12 and two side walls 13 integrally connected to each other, and the lower housing 16 has a bottom wall 14. The upper plate 181 of the compartment frame 18 forms a bottom wall 14' defining the upper insertion channel 11, and the lower plate 182 of the compartment frame 18 forms a top wall 12' defining the lower insertion channel 11. More specifically, the upper insertion channel 11 is defined by the top wall 12 and the two side walls 13 of the upper housing 15 and the upper plate 181 (bottom wall 14') of the compartment frame 18, and the lower insertion channel 11 is defined by the two side walls 13 of the upper housing 15, the bottom wall 14 of the lower housing 16 and the lower plate 182 (top wall 12') of the compartment frame 18. The upper plate 181 (bottom wall 14') of the compartment frame 18 forms an insert 143' and two support plates 144' on the left and right. The insert 143' is connected between the two support plates 144' and protrudes upward. The length of the two support plates 144' extending backward is longer than the length of the support plates 144 on the bottom wall 14, and is used to support the bottom surface of the socket housing 21 above. A protrusion 145' is formed on each of the two support plates 144' to support the receiving recess 213 on the bottom surface of the socket housing 21 above.

[0114] In addition, in this second embodiment, a front insertion portion 131a is provided on the recess 131 formed on the bottom edge near the front end of each side wall 13 of the upper housing 15, and a front insertion hole 141a is provided on each of the two protrusions 141 integrally formed on the bottom wall 14 of the lower housing 16 that are facing upward, which corresponds to and cooperates with the front insertion portion 131a. The front insertion portion 131a is inserted into the front insertion hole 141a, thereby strengthening the assembly strength between the upper housing 15 and the lower housing 16.

[0115] Furthermore, in this second embodiment, the socket connector 2 comprises two socket housings 21 arranged vertically and respectively inserted into the two insertion channels 11. Each sidewall 13 also has an integrally formed anti-reverse baffle 137 behind the stop block 134. The anti-reverse baffle 137 blocks the rear ends of the two socket housings 21 to prevent the socket connector 2 from moving backward. Specifically, the rear edge of the anti-reverse baffle 137 is integrally connected to the body of the corresponding sidewall 13, and the other three edges are cut out from the sidewall 13 and offset inward so that the anti-reverse baffle 137 extends obliquely forward and inward. The front edge of the anti-reverse baffle 137 directly abuts against the rear end of the socket housing 21. The anti-reverse baffle 137 on the sidewall 13 of the shield 1 blocking the rear end of the socket housing 21 further prevents the socket connector 2 from moving backward. This further increases the assembly strength and integrity between the socket connector 2 and the shield 1.

[0116] The back cover 3 has two pressure springs 34 that apply pressure forward to the rear ends of the two socket housings 21. For example, the pressure springs 34 are spring structures cut from the body of the back cover 3 and folded inward. In addition, the back cover 3 has multiple upper fasteners 32' that are inserted into the rear end of the top wall 12 of the upper housing 15 of the shielding cover 1. The multiple upper fasteners 32 can enhance the bonding strength between the back cover 3 and the upper housing 15 of the shielding cover 1.

[0117] In summary, the stop 134 in this invention has a three-dimensional convex structure, resulting in high strength and resistance to deformation. It also guides the socket connector 2 into the shielding cover 1 during assembly. Furthermore, the upper flange 134a of the stop 134 prevents the socket connector 2 from moving downwards relative to the shielding cover 1, while the rear flange 134b of the stop 134 prevents the socket connector 2 from moving forward relative to the shielding cover 1. Secondly, since the insert 143 of the bottom wall 14 of the shielding cover 1 is inserted into the slot 212 at the bottom of the socket housing 21, and the support plate 144 of the bottom wall 14 of the shielding cover 1 is supported at the bottom of the socket housing 21, the assembly strength of the socket connector 2 and the shielding cover 1 is enhanced. Furthermore, by applying forward pressure to the pressure spring 34 of the rear cover 3 at the rear end of the socket housing 21, the backward movement of the socket connector 2 is prevented, and the assembly position of the socket connector 2 is positioned. Furthermore, the anti-reverse baffle 137 on the side wall 13 of the shield 1, which blocks the rear end of the socket housing 21, further prevents the socket connector 2 from moving backward. The above-described structure increases the assembly strength and integrity between the socket connector 2 and the shield 1, improving not only its resistance to external forces but also the accuracy of the assembly position.

[0118] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
