Description

Technical Field

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

[0002] Chinese Utility Model Patent Publication No. CN204257893U discloses an electrical connector. The connector's insulating body has a first insertion interface and a second insertion interface, and a recessed retaining cavity located between the first and second insertion interfaces. The retaining cavity is used to insert and position a retaining protrusion of a metal heat sink. The retaining protrusion of the metal heat sink extends rearward from the main body to insert and position into the retaining cavity of the insulating body. A partition has rearwardly extending insertion portions located on the upper and lower sides of the retaining protrusion of the metal heat sink, which are used to insert into the insulating body. With this arrangement, the partition and the metal heat sink within the partition can be stably fixed to the side wall of the metal shell and the insulating body. However, this application discloses how to use the insulating body to position the metal heat sink and the partition, but does not disclose the support structure used to support the upper and lower connectors (of the insulating body).

[0003] Chinese invention patent publication CN110829064A discloses an electrical connector, in which a fixing cover is provided on the rear side to fix the cable and secure it to a circuit board. The fixing cover includes a plate-shaped portion and a fastening portion disposed on the rear side of the plate-shaped portion. The plate-shaped portion has several wire-passing holes, through which the cable passes and is then soldered to the conductive terminals of the electrical connector. However, the cable disclosed in this application must pass through the wire-passing holes of the fixing cover before at least one end is terminated to the connector. If both ends of the cable are assembled first, the fixing cover cannot be assembled. Secondly, the cables must pass through the wire-passing holes of the fixing cover one by one, which is labor-intensive and time-consuming. Furthermore, the wire-passing holes are perforations directly punched into the metal fixing cover, and the edges of these holes are sharp, which can easily scratch or even damage the cable. Summary of the Invention

[0004] Therefore, one object of the present invention is to provide a connector assembly that can improve at least one problem in the prior art.

[0005] Therefore, in some embodiments of the connector assembly of the present invention, a shielding cover and a socket connector are included. The shielding cover includes a housing, a partition frame disposed on the housing, and two insertion channels defined by the housing and the partition frame and separated vertically by the partition frame. The socket connector is disposed at the rear section of the shielding cover and includes two socket housings arranged vertically and respectively disposed in the two insertion channels, and a plurality of socket terminals. The partition frame has a support structure located at the rear section and supported between the two socket housings. The support structure includes an upper support plate, a lower support plate, and a support block disposed between the upper support plate and the lower support plate.

[0006] In some embodiments, the compartment frame has a central slot located at the rear and extending front to back, and two support structures separated left and right by the central slot. The socket connector also includes an intermediate housing disposed between the two socket housings and at least partially accommodated in the central slot. The two socket housings and the intermediate housing together define two channels located on the left and right sides of the intermediate housing. The two support structures of the compartment frame are respectively located in the two channels.

[0007] In some embodiments, the upper support plate and the lower support plate each have a plurality of positioning protrusions located around the support block for positioning the support block.

[0008] In some embodiments, the connector also includes two socket housings passing through the socket connector and a pin in the support structure.

[0009] In some embodiments, the pin has a tail portion fixed to a circuit board.

[0010] In some embodiments, the pin is connected to the grounding component of the socket connector and the grounding line of the circuit board.

[0011] Therefore, in some embodiments of the connector assembly of the present invention, a shielding cover, a receptacle connector, a rear cover, and a cable organizer are included. The shielding cover includes a mating channel with a rearward opening. The receptacle connector is disposed at the rear of the shielding cover and includes a receptacle housing, a plurality of receptacle terminals, and a plurality of cables respectively connected to at least a portion of the plurality of receptacle terminals and extending rearwardly out of the rearward opening. The rear cover is assembled to the rearward opening of the shielding cover and includes a rear wall having a cable organizer assembly portion. The cable organizer is assembled to the cable organizer assembly portion of the rear wall and has cable organizing holes through which the plurality of cables of the receptacle connector exit rearwardly.

[0012] In some embodiments, the rectifier has two halves that are joined together.

[0013] In some embodiments, the two halves of the rectifier have the same construction and can be combined with each other.

[0014] In some embodiments, the aligner assembly includes a recess integrally formed in the rear wall, and the aligner is assembled within the recess.

[0015] In some embodiments, each half has a groove formed at its outer periphery that corresponds to the edge of the recess.

[0016] In some embodiments, each half has complementary engagement protrusions and engagement recesses.

[0017] In some embodiments, the aligner assembly includes two recesses integrally formed on the rear wall and arranged side by side, and a spacer between the two recesses. Each half has two sides respectively assembled in the two recesses, and a spacer with a through groove between the two sides. The spacer is inserted into the through groove of the spacer of the two half.

[0018] In some embodiments, each half has a plurality of engagement protrusions and a plurality of engagement recesses formed on the side portion and the spacer portion.

[0019] In some embodiments, the connector assembly includes two rectifiers, and the rear wall has two rectifier assemblies, one above and one below, each with one rectifier assembled thereon. The opening of the recess in the upper rectifier assembly faces upward, and the opening of the recess in the lower rectifier assembly faces downward.

[0020] The support structure of the compartment frame in this invention is supported between the two socket housings, and the support structure includes a support block disposed between the upper support plate and the lower support plate, thus reliably providing strong support between the two socket housings. Secondly, the pins passing through the two socket housings and the support structure further maintain the relative position between the two socket housings and the support structure, increasing the support strength of the support structure; the pins can also serve as grounding components. Furthermore, the cable organizer assembled on the rear cover allows multiple cables to exit from the rear, providing cable organization and positioning. Moreover, the cable organizer, composed of two halves, can be easily and separately assembled onto the rear cover with the cables already assembled. The cable organizer can also be made of insulating material, so the edge of the cable organizing hole is less sharp than that of the rear cover, thus protecting the cables exiting the rear cover from scratches.

[0161] See Figures 1 to 4An embodiment of the connector assembly 100 of the present invention is suitable for insertion 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 mechanically and electrically connected to the plug plate 202. The connector assembly 100 includes a shielding cover 1, a socket connector 2, two pins 3, an upper heat dissipation module 4, a lower heat dissipation module 5, a rear cover 6, and two cable straighteners 7.

[0162] 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 includes a cover body 11, a partition frame 12 disposed on the cover body 11, and two insertion channels 13 defined by the cover body 11 and the partition frame 12 and separated vertically by the partition frame 12. The cover body 11 extends along a front-back direction D1 (the direction indicated by the arrow is front, and the opposite direction is back) and includes a top wall 111, two side walls 112 that are spaced apart from each other and connected to both sides of the top wall 111 along a left-right direction D2 (the direction indicated by the arrow is right, and the opposite direction is left), and a bottom wall 113 that is spaced apart from the top wall 111 along a vertical direction D3 (the direction indicated by the arrow is up, and the opposite direction is down) and connected to the bottom edge of the two side walls 112.

[0163] In this embodiment, the cover 11 includes an upper shell 114 and a lower shell 115 assembled together to form the insertion channel 13. The upper shell 114 has a top wall 111 and two side walls 112 integrally connected to each other. The lower shell 115 has a bottom wall 113 and is assembled to the two side walls 112 of the upper shell 114. Each side wall 112 of the upper shell 114 has a recess 112a formed near its front end at its bottom edge, and each side wall 112 has a plurality of fasteners 112b and a downward-facing insertion hole 112c. The bottom wall 113 of the lower shell 115 integrally forms two protrusions 113a corresponding to the recesses 112a of the two side walls 112, and two side plates 113b corresponding to the outer sides of the two side walls 112. The recess 112a has a front insertion portion 112d, and the protrusion 113a has a front insertion hole 112c that corresponds to and engages with the front insertion portion 112d. The front insertion portion 112d is inserted into the front insertion hole 112c. Each side plate 113b has a plurality of fastening holes 113d that engage with the fastening blocks 112b of the corresponding side wall 112, and an insertion portion 113e that is inserted upward into the insertion hole 112c of the corresponding side wall 112, thereby enabling the bottom wall 113 of the lower shell 115 to be assembled and joined to the two side walls 112 of the upper shell 114.

[0164] See Figures 1 to 5 The partition frame 12 has an upper wall 121 and a lower wall 122 spaced apart vertically, two side connecting walls 123 spaced apart horizontally between the upper wall 121 and the lower wall 122, a front connecting wall 124 located at the front end between the upper wall 121 and the lower wall 122, and a plurality of fixing flaps 125 formed on the side edges of the upper wall 121 and the lower wall 122. Each side wall 112 of the shield 1 also has a plurality of fixing through holes 112e corresponding to the plurality of fixing flaps 125. The plurality of fixing flaps 125 are bent after passing through the plurality of fixing through holes 112e so that the partition frame 12 is assembled to the two side walls 112 of the shield 1. The upper insertion channel 13 is defined by the top wall 111, the two side walls 112 and the upper wall 121 of the compartment frame 12, and the lower insertion channel 13 is defined by the two side walls 112, the bottom wall 113 and the lower wall 122 of the compartment frame 12. Each insertion channel 13 has a front insertion port 131 at the front end for the pluggable module 200 to be inserted, and a rear opening 132 at the rear end.

[0165] See Figures 2 to 6The socket connector 2 is located at the rear end of the shield 1 and includes two socket housings 21 arranged vertically and respectively opening 132 from the two rear ends into the two insertion channels 13, an intermediate housing 22 located between the two socket housings 21, a plurality of socket terminals 23, and a plurality of cables 24. Each socket housing 21 has a forward-facing insertion slot 211, and the plurality of socket terminals 23 are located in the socket housing 21 and extend into the insertion slot 211. In this embodiment, the socket connector 2 further includes a plurality of terminal fixing blocks 25 and 26 that partially cover the plurality of socket terminals 23. The terminal fixing block 25 located in the middle and having a vertical structure constitutes the intermediate housing 22, and the tails 32 of the plurality of socket terminals 23 located on the vertically constructed terminal fixing block 25 extend from the bottom of the intermediate housing 22. The terminal fixing blocks 26 located on the left and right sides and having a horizontal structure are located on the two socket housings 21, and the terminal tails 231 of the plurality of socket terminals 23 located on the horizontally constructed terminal fixing blocks 26 are respectively connected to the plurality of cables 24, and the plurality of cables 24 extend from the rear ends of the two socket housings 21.

[0166] See Figures 5 to 8 The partition frame 12 also has a central slot 126 located at the rear and extending front to back, and two support structures 127 located at the rear and supported between the two socket housings 21. The two support structures 127 are separated left and right by the central slot 126. It should be noted that the partition frame 12 may not have the central slot 126 in other embodiments, and the number of support structures 127 may be only one or more, not limited to this embodiment. Each support structure 127 includes an upper support plate 127a integrally formed at the rear of the upper wall 121, a lower support plate 127b integrally formed at the rear of the lower wall 122, and a support block 127c disposed between the upper support plate 127a and the lower support plate 127b. The upper support plate 127a and the lower support plate 127b each have a plurality of positioning protrusions 127d and 127e located around the support block 127c for positioning the support block 127c. Specifically, the central slot 126 partially accommodates the central housing 22, and the two socket housings 21 and the central housing 22 together define two channels 27 located on the left and right sides of the central housing 22. The two support structures 127 of the partition frame 12 are respectively located in the two channels 27 to support the two socket housings 21.

[0167] See Figures 3 to 4 and Figures 7 to 9The two pins 3 pass through the two socket housings 21 of the socket connector 2 and correspondingly through the two support structures 127. Each socket housing 21 has a first through hole 212 for the pin 3 to pass through, each upper support plate 127a has a second through hole 127f for the pin 3 to pass through, each lower support plate 127b has a third through hole 127g for the pin 3 to pass through, and each support block 127c has a fourth through hole 127h for the pin 3 to pass through. In this embodiment, the pin 3 has an interference protrusion 31 that interferes with the inner wall surface of the first through hole 212 to strengthen the fixing force, and a tail portion 32 located at the lower end and having a pinhole-shaped press-fit structure. The bottom of the connector assembly 100 is disposed on a circuit board 300. The tail 32 of each pin 3 is used to be inserted downward into a conductive through hole 301 fixed on the circuit board 300, and the pin 3 is connected to the grounding member 213 in the socket housing 21 of the socket connector 2 (see...). Figure 9 For example, it could be a grounding terminal or a grounding component) and the grounding line of the circuit board 300. In addition, in this embodiment, the cover 11 of the shield 1 also has a bottom opening 116 located behind the bottom wall 113. The bottom opening 116 is used for the tail 32 of the pin 3 and the terminal tail 231 of the socket terminal 23 of the socket connector 2 located in the intermediate housing 22 to pass through and be disposed on the circuit board 300.

[0168] Since the support structure 127 of the compartment frame 12 is supported between the two socket housings 21, and the support structure 127 includes the support block 127c disposed between the upper support plate 127a and the lower support plate 127b, it can reliably provide strong support between the two socket housings 21. Secondly, the pin 3 passing through the two socket housings 21 and the support structure 127 further maintains the relative position between the two socket housings 21 and the support structure 127, thereby increasing the support strength of the support structure 127. Furthermore, the pin 3 can also be connected to the grounding member 213 in the socket housing 21 of the socket connector 2 and the grounding line of the circuit board 300, serving as a grounding member.

[0169] After the pluggable module 200 enters the corresponding insertion channel 13 of the shield 1 through any of the front insertion ports 131, the insertion plate 202 at the end of the insertion portion 201a of the pluggable module 200 can be inserted into the corresponding insertion slot 211 of the socket housing 21 in the socket connector 2, so that the contact fingers 202a of the insertion plate 202 contact the socket terminal 23 in the insertion slot 211 of the socket housing 21, so that the pluggable module 200 and the socket connector 2 of the connector assembly 100 mate with each other. In addition, a mounting hole (not shown) can be provided in a housing (not shown) near the front insertion port 131 at the front section of the shield 1. The shield 1 also includes a plurality of first grounding members 14 provided in the cover body 11 near the two front insertion ports 131, and a second grounding member 15 provided in the front connecting wall 124 of the compartment frame 12. The first grounding member 14 has a plurality of first elastic fingers 141 extending rearward from the front socket 131 and distributed on the outer and inner sides. The outermost of the plurality of first elastic fingers 141 partially contacts the periphery of the mounting hole on the housing, while the innermost of the plurality of first elastic fingers 141 contacts the housing 201 of the pluggable module 200. The second grounding member 15 has a plurality of second elastic fingers 151 extending rearward from the front connecting wall 124 and distributed on the upper and lower sides of the compartment frame 12. The plurality of second elastic fingers 151 contacts the housing 201 of the pluggable module 200.

[0170] See Figure 2 , Figure 3 and Figure 6The shield 1's cover 11 also has a top opening 117 formed on the top wall 111 and communicating with the upper insertion channel 13. The upper heat dissipation module 4 includes an upper heat sink 41 and two elastic fasteners 42 disposed on the two side walls 112 of the shield 1 and assembled to the top wall 111 of the shield 1. The upper heat sink 41 has a plurality of upper heat dissipation fins 412 that are attached side by side to each other on the top surface of the upper heat dissipation base plate 411 from above on the top wall 111, and are for example welded to each other. It also has two receiving grooves 413 formed on the plurality of upper heat dissipation fins 412 that are arranged side by side along the front-rear direction D1 and correspond to the two elastic fasteners 42. The upper heat dissipation substrate 411 has an upper heat dissipation coupling portion 411a formed at the bottom. The upper heat dissipation coupling portion 411a extends downward into the upper insertion channel 13 through the top opening 117. Each elastic fastener 42 has a pressing portion 421 provided in the corresponding receiving groove 413 and used to press downward and elastically against the upper heat sink 41, and two fastening portions 422 extending downward from the left and right ends of the pressing portion 421 and fastening to the two side walls 112 of the shielding cover 1. Each sidewall 112 is formed with a snap-fit ​​protrusion 112f, and each snap-fit ​​portion 422 is formed with a snap-fit ​​hole 422a that snaps into the snap-fit ​​protrusion 112f. Furthermore, the snap-fit ​​protrusion 112f has a downward-facing hole 112h, and the snap-fit ​​hole 422a has an upward-facing insert 422b for insertion into the hole 112h, thereby further increasing the holding force between the snap-fit ​​portion 422 and the snap-fit ​​protrusion 112f. Through the downward pressing force provided by the two elastic fasteners 42, it is ensured that when the pluggable module 200 is inserted into the upper insertion channel 13, the upper heat dissipation coupling portion 411a of the upper heat sink 41 can maintain as complete a contact as possible with the top surface of the housing 201 of the pluggable module 200. In addition, each of the fastening parts 422 has an outwardly folded and protruding unlocking hook 422c at its bottom. The unlocking hooks 422c of the two fastening parts 422 of the same elastic buckle 42 are staggered in the front-back direction D1. Therefore, when the two connector assemblies 100 are placed side by side, the adjacent unlocking hooks 422c on the two connector assemblies 100 can be staggered, thereby making it easier to unlock the elastic buckle 42.

[0171] Additionally, it should be noted that in this embodiment, the cover 11 also has a baffle 117a extending downward from the rear edge of the top opening 117, and a guide piece 117b extending downward from the side edge of the top opening 117. The top surface of the pluggable module 200's plug-in portion 201a has a stop portion 201b that can be blocked by the baffle 117a, and a guide groove 201c for accommodating the guide piece 117b to generate a guiding effect.

[0172] See Figure 6 and Figure 10 The partition frame 12 of the shielding cover 1 also has an internal space 128 defined by the upper wall 121, the lower wall 122, the two side connecting walls 123, and the front connecting wall 124, and a lower opening 129 formed on the lower wall 122 and communicating between the internal space 128 and the lower insertion channel 13. The lower heat dissipation module 5 is disposed in the internal space 128 and has a lower heat sink 51 and an elastic bias member 52. The lower heat sink 51 has a lower heat dissipation base plate 511 disposed on the lower wall 122, and a plurality of lower heat dissipation fins 512 that are snapped together side by side and, for example, welded to the top surface of the lower heat dissipation base plate 511. The lower heat dissipation base plate 511 has a lower heat dissipation coupling portion 511a formed at the bottom, which extends downward into the lower insertion channel 13 through the lower opening 129. The elastic biasing member 52 is disposed between the lower heat sink 51 and the upper wall 121 of the partition frame 12, and has a body 521 disposed on the lower heat sink 51, and a plurality of elastic pieces 522 integrally formed from the body 521 upward and backward and used to abut against the upper wall 121. Through the elastic force provided by the plurality of elastic pieces 522, it can be ensured that when the pluggable module 200 is inserted into the lower insertion channel 13, the lower heat dissipation coupling part 511a of the lower heat sink 51 can maintain contact with the top surface of the housing 201 of the pluggable module 200 as completely as possible.

[0173] Furthermore, it should be noted that in this embodiment, each side wall 112 of the cover 11 also has two side openings 112i corresponding to the two insertion channels 13, and two locking tabs 112j extending inward and backward from the front edge of the side openings 112i. The locking tabs 112j are used to engage with the locking recesses 201d on the side of the insertion portion 201a of the pluggable module 200 to create a locking effect on the pluggable module 200 inserted into the insertion channel 13. Moreover, the lower side opening 112i is blocked by the front stop 113f at the front section of the side plate 113b of the bottom wall 113, and the upper side opening 112i is blocked by the blocking tab 118 provided on the side wall 112, thereby reducing the influence of the side openings 112i on the electromagnetic mask effect. The shielding plate 118 has a fixing through hole 118a through which one of the fixing flaps 125 of the compartment frame 12 passes and is bent and fixed, and a fixing insert 118b extending upward and inserted into the fixing insertion hole 112k of the side wall 112.

[0174] See Figures 11 to 15In the socket connector 2, the multiple cables 24 connected to the multiple socket terminals 23 extend rearward out of the rear end openings 132 of the two insertion channels 13. The back cover 6 is, for example, made of metal. The back cover 6 is assembled at the rear end openings 132 of the two insertion channels 13 of the shielding cover 1. The back cover 6 includes a rear wall 61, two side fasteners 62 extending forward from the left and right sides of the rear wall 61 to overlap the side walls 112 of the shielding cover 1, multiple upper fasteners 63 extending upward from the upper edge of the rear wall 61 and inserted into the rear end of the top wall 111 of the shielding cover 1, and multiple fastening holes 64 formed at the connection between the side fasteners 62 and the rear wall 61. Each sidewall 112 of the shielding cover 1 also has a plurality of fastening tabs 112g extending rearward from the rear end edge. The plurality of fastening tabs 112g are used to pass through the plurality of fastening holes 64 and then bend inward (not yet bent in the figure). In detail, in this embodiment, the two side fastening tabs 62 of the rear cover 6 extend forward and inward at an inward angle and have their ends folded outward. The two side fastening tabs 62 are pressed inward against the two side walls 112 of the shielding cover 1 with a positive force.

[0175] The rear wall 61 has two cable assemblies 611, one above and one below, each equipped with one of the cable assemblies 7. Each cable assembly 611 includes two recesses 611a integrally formed on the rear wall 61 and arranged side by side, and a spacer 611b located between the two recesses 611a. The recesses 611a have a U-shaped structure, with the opening of the recess 611a of the upper cable assembly 611 facing upwards and the opening of the recess 611a of the lower cable assembly 611 facing downwards.

[0176] For example, the two cable straighteners 7 are made of insulating material, and are respectively assembled to the cable straightener assembly portion 611 of the rear wall 61. Each cable straightener 7 has two halves 71 that are vertically connected to each other, and two cable straightening holes 72 that are defined by the two halves 71 and distributed horizontally. The multiple cables 24 of the socket connector 2 are divided into four groups and pass through the four cable straightening holes 72 of the two cable straighteners 7 respectively. In detail, in this embodiment, the two halves 71 of the cable straightener 7 have the same structure and can be combined with each other. Each half 71 has two side portions 711 respectively assembled in the two recesses 611a, a spacer portion 712 located between the two side portions 711 and having a through groove 712a, and a plurality of connecting protrusions 713 and a plurality of connecting recesses 714 formed in the side portions 711 and the spacer portion 712. The spacer 611b is inserted into the slot 712a of the spacer portion 712 of the two halves 71. Through the cooperation of the spacer 611b and the slot 712a, the cable straightener 7 can be securely assembled to the cable straightener assembly portion 611. The engaging protrusion 713 and engaging recess 714 of the two halves 71 are complementary and used for mutual assembly. Furthermore, each half 71 also has a groove 715 formed on its outer periphery that corresponds to the edge of the recess 611a, thereby further strengthening the assembly strength between the cable straightener 7 and the rear wall 61 of the rear cover 6. Figure 12 As shown, since the cable aligner 7 is composed of two interlocking halves 71, the cable aligner assembly part 611 of the back cover 6 can first insert one half 71, so that the back cover 6 can be inserted between the cables 24 when the cables 24 are already assembled, and the cables 24 can be placed into the cable alignment hole 72 of one half 71. Then the other half 71 is then assembled, so that the cables 24 can be gradually assembled into the cable alignment hole 72 of the cable aligner 7 on the back cover 6 when the cables 24 are already assembled, and the back cover 6 is assembled at the rear end opening 132 of the two insertion channels 13 of the shielding cover 1.

[0177] The cable organizer 7, assembled on the rear cover 6, allows multiple cables 24 to exit from the rear, and provides cable organization and positioning functions. Furthermore, the cable organizer 7, composed of two halves 71, can be easily and separately assembled onto the rear cover 6 with the cables 24 already assembled. The cable organizer 7 can be made of an insulating material, so the edge of the cable organizing hole 72 is less sharp than that of the rear cover 6, thus protecting the cables 24 exiting from the rear cover 6 from scratches.

[0178] It should be noted that the number of cable groups 24, the number of cable straighteners 7, and the number of cable straightening holes 72 in the cable straighteners 7 can all be adjusted according to requirements and should not be limited to the number in this embodiment.

[0179] See Figure 6 and Figure 15 Furthermore, in this embodiment, the rear wall 61 of the rear cover 6 also has two pressure springs 612 integrally formed and pressing forward against the rear ends of the two socket housings 21 of the socket connector 2. These two pressure springs 612 can better position the assembly position of the socket connector 2. In detail, the pressure springs 612 are spring structures cut out from the rear wall 61 and folded forward.

[0180] In summary, the support structure 127 of the compartment frame 12 of the present invention is supported between the two socket housings 21, and the support structure 127 includes the support block 127c disposed between the upper support plate 127a and the lower support plate 127b, thus reliably providing strong support between the two socket housings 21. Secondly, the pin 3 passing through the two socket housings 21 and the support structure 127 further maintains the relative position between the two socket housings 21 and the support structure 127, increasing the support strength of the support structure 127, and the pin 3 can also serve as a grounding component. Furthermore, the cable organizer 7 assembled on the rear cover 6 allows multiple cables 24 to exit from the rear, providing cable organization and positioning. Moreover, the cable organizer 7, composed of the two halves 71, can be easily and separately assembled onto the rear cover 6 with the cables 24 already assembled. The cable straightener 7 can be made of an insulating material, so the edge of the cable straightening hole 72 of the cable straightener 7 is less sharp than that of the back cover 6, thus protecting the cable 24 coming out of the back cover 6 from being scratched.

[0181] 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.
