Description

Technical Field

[0001] The present invention relates to a connector assembly, and more particularly to a connector assembly having a compartment bracket. Background Art

[0002] Chinese Patent Publication No. CN106469878A (corresponding to US Patent No. US1,015,357) discloses a connector system. The cover of the connector system includes an intermediate portion, which includes an upper wall and a lower wall. The upper wall and the lower wall together define an upper port and a lower port in the cover. The lower wall includes a hole formed therein such that the intermediate portion communicates with the lower port. A biasing heat sink of the connector system is disposed in the intermediate portion between the upper port and the lower port, and the biasing heat sink extends through the hole into the lower port. The cover disclosed in this connector system is positioned on a stacked connector, and an opening formed at the bottom of the cover enables the stacked connector to be disposed inside the cover. The rear end of the intermediate portion must extend between two sockets above and below the stacked connector. Therefore, when the assembly sequence of the stacked connector and the cover is after the assembly sequence of the intermediate portion and the cover, the intermediate portion of the cover will interfere with the stacked connector, making it impossible for the stacked connector to enter the cover smoothly. Summary of the Invention

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

[0004] Thus, in some embodiments, the connector assembly of the present invention includes a guiding shield, a socket connector, and a partition frame. The socket connector is disposed at the rear section inside the guiding shield, and the socket connector has an upper socket and a lower socket. The partition frame includes a compartment bracket and an extension bracket. The compartment bracket is disposed inside the guiding shield and jointly defines an upper accommodation space corresponding to the upper socket and a lower accommodation space corresponding to the lower socket with the guiding shield. The rear end of the compartment bracket is located in front of the front ends of the upper socket and the lower socket. The extension bracket is assembled to the rear end of the compartment bracket, and the extension bracket can move relative to the compartment bracket between a front position in front of the front ends of the upper socket and the lower socket and a rear position at least partially extending between the upper socket and the lower socket.

[0005] In some embodiments, it further includes a retaining member. The extension bracket has a first retaining portion that is snapped to the retaining member in the front position and a second retaining portion that is snapped to the retaining member in the rear position.

[0006] In some embodiments, the retaining member is an elastic retaining piece formed on the side wall of the guiding shielding cover. The side wall of the extension bracket has a side plate corresponding to and cooperating with the elastic retaining piece. The trailing edge of the side plate constitutes the first retaining portion, and the leading edge of the side plate constitutes the second retaining portion.

[0007] In some embodiments, the side wall of the extension bracket further has a limiting hole adjacent to the side plate behind the side plate, and the side wall of the guiding shielding cover has a limiting piece correspondingly extending into the limiting hole.

[0008] In some embodiments, the inner front edge of the limiting hole and the trailing edge of the side plate together constitute the first retaining portion.

[0009] In some embodiments, the side wall of the compartment bracket has an avoidance opening for the elastic retaining piece and the limiting piece to pass through.

[0010] In some embodiments, each of the two side walls of the extension bracket has a guiding piece, and each of the two side walls of the guiding shielding cover has a guiding rail groove, and the guiding piece is slidably disposed in the guiding rail groove in the front-back direction.

[0011] In some embodiments, each of the two side walls of the compartment bracket has a guiding piece receiving notch at the rear end. When the extension bracket is in the front position, the guiding piece is received in the guiding piece receiving notch.

[0012] In some embodiments, the extension bracket has a lower stop portion extending into the lower accommodation space. When the extension bracket is in the front position, a pluggable module entering the lower accommodation space can push against the lower stop portion, causing the extension bracket to move backward to the rear position.

[0013] In some embodiments, the compartment bracket has an upper wall and a lower wall that jointly define an inner accommodation space. The lower wall is formed with a lower opening window that communicates the inner accommodation space with the lower accommodation space. The connector assembly further includes an internal biasing radiator disposed in the inner accommodation space of the compartment bracket. The internal biasing radiator has an internal heat dissipation member passing through the lower opening window into the lower accommodation space. The internal heat dissipation member can be moved up and down. The extension bracket is sleeved on the internal heat dissipation member and is sleeved by the compartment bracket.

[0014] The connector assembly of the present invention can avoid interference problems between the partition and the socket connector during the assembly process through the extension bracket of the partition that can move between the front position and the rear position, facilitating the assembly operation.

[0104] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0105] Refer to Figures 1 to 4 , an embodiment of the connector assembly 100 of the present invention is adapted to be disposed on a circuit board 200 and is adapted to be plugged into a pluggable module 300. The connector assembly 100 includes a guiding shield 1, a socket connector 2, a partition frame 3, and an internal bias radiator 4.

[0106] The guiding shield 1 is, for example, constructed by stamping and bending a metal plate.

The plurality of press-fit pins 15 are used to press into a plurality of press-fit holes 201 of the circuit board 200 so that the guiding shield 1 is fixedly disposed on the circuit board 200 and can be electrically connected to the ground line (not shown) of the circuit board 200.

[0107] The socket connector 2 is disposed on the circuit board 200 and at the rear section within the guiding shield 1. The socket connector 2 has an insulating housing 21, and a plurality of terminals 22 disposed in the housing 21. The housing 21 has an upper socket 211 and a lower socket 212 that face forward and are arranged along the up-down direction D2. Each terminal 22 has a contact portion 221 located in the upper socket 211 or the lower socket 212, and a tail portion 222 that extends downward from the bottom of the housing 21 and is used for mechanically and electrically connecting to the circuit board 200.

[0108] The partition frame 3 includes a compartment bracket 31 and an extension bracket 32. The compartment bracket 31 is disposed within the guiding shield 1 and, together with the guiding shield 1, defines an upper accommodation space 16 corresponding to the upper socket 211 of the socket connector 2 and a lower accommodation space 17 corresponding to the lower socket 212 of the socket connector 2. Further, the rear sections of the upper accommodation space 16 and the lower accommodation space 17 communicate with each other. The upper accommodation space 16 has an upper socket opening 161 located in the front for inserting the pluggable module 300. The lower accommodation space 17 has a lower socket opening 171 located in the front for inserting the pluggable module 300, and a bottom opening 172 located at the rear of the bottom and defined by the side wall 12, the bottom wall 13, and the rear wall 14 of the guiding shield 1. The bottom opening 172 allows the socket connector 2 to enter so that the socket connector 2 is accommodated in the rear sections of the upper accommodation space 16 and the lower accommodation space 17 that are in communication. In this embodiment, the compartment bracket 31 has an upper wall 311 and a lower wall 312 that face each other up and down, a front wall 313 connected to the front edges of the upper wall 311 and the lower wall 312, and two side walls 314 connected to the side edges of the upper wall 311 and the lower wall 312. The upper wall 311, the lower wall 312, the front wall 313, and the two side walls 314 together define an inner accommodation space 315. Each side wall 12 of the guiding shield 1 has a fixing hole 121 formed therethrough. The compartment bracket 31 further has fixing tabs 316 that extend to the outside of the two side walls 314. The fixing tabs 316 are respectively inserted through the fixing holes 121 of the two side walls 12 and then bent and fixed, thereby stably assembling the compartment bracket 31 in the guiding shield 1.

[0109] Continue to refer to Figures 1 to 4, in this embodiment, the connector assembly 100 can be disposed in a mounting hole (not shown in the figure) of a chassis (not shown in the figure). The guiding shield 1 is provided with a plurality of first grounding members 18 at the front end. The partition bracket 31 is further provided with a second grounding member 317 at the front section of the front wall 313, the front section of the upper wall 311, and the front section of the lower wall 312. The first grounding member 18 has a plurality of elastic fingers 181 extending rearward from the front end of the guiding shield 1 and distributed on the outer side and the inner side of the guiding shield 1. Among the plurality of elastic fingers 181, those located on the outer side of the guiding shield 1 are used to contact the edge of the mounting hole of the chassis, and those located on the inner side of the guiding shield 1 are used to contact the pluggable module 300. The second grounding member 317 has a sheet body 317a provided on the front side of the front wall 313 of the partition bracket 31, and two grounding sheets 317b respectively extending rearward from the upper edge and the lower edge of the sheet body 317a to extend into the upper accommodation space 16 and the lower accommodation space 17. Each grounding sheet 317b has a plurality of elastic fingers 317c extending rearward and used to contact the pluggable module 300.

[0110] The pluggable module 300 has a housing 301 and a plug-in circuit board 302. The housing 301 has a plug-in portion 301a for inserting into the upper accommodation space 16 and the lower accommodation space 17. The plug-in circuit board 302 is protrudingly provided on the plug-in portion 301a and is used for plugging into the upper socket 211 and the lower socket 212. Each side wall 12 of the guiding shield 1 has two openings 122 respectively corresponding to the upper accommodation space 16 and the lower accommodation space 17. At each opening 122, an inwardly extending elastic piece 123 is formed and extends obliquely inward and rearward into the guiding shield 1. The left and right sides of the plug-in portion 301a of the pluggable module 300 are provided with locking grooves 301b corresponding to and cooperating with the inwardly extending elastic pieces 123. The inwardly extending elastic pieces 123 at the plurality of openings 122 are used to cooperate with the locking grooves 301b of the pluggable module 300 inserted into the upper accommodation space 16 or the lower accommodation space 17 to produce a locking effect. In addition, a positioning structure 301c is formed at the front top of the plug-in portion 301a of the housing 301. The top wall 11 of the guiding shield 1 is formed with an upper window 111 communicating with the upper accommodation space 16, and an upper stop portion 112 extending downward from the rear section of the upper window 111 into the upper accommodation space 16. The upper stop portion 112 is used to stop at the positioning structure 301c to limit the insertion position of the pluggable module 300. The lower wall 312 of the partition bracket 31 is formed with a lower window 312a for communicating the inner accommodation space 315 with the lower accommodation space 17.

[0111] The built-in bias radiator 4 is disposed in the inner accommodation space 315 of the compartment bracket 31 and has a built-in heat sink 41, and a bias spring 42 disposed between the built-in heat sink 41 and the upper wall 311 of the compartment bracket 31. The built-in heat sink 41 has a substrate 411, and a plurality of heat dissipation fins 412 that are fastened to each other side by side in the left-right direction D3 and are disposed on the top surface of the substrate 411. The substrate 411 has a heat coupling portion 411a that passes through the lower opening window 312a and enters the lower accommodation space 17. The bias spring 42 has a pressing plate 421 that presses against the top of the heat dissipation fins 412 of the built-in heat sink 41, and a plurality of plate-shaped spring pieces 422 that extend from the pressing plate 421 and abut against the upper wall 311 of the compartment bracket 31. It should be noted that the bias spring 42 can also be in other spring structures, not limited to this embodiment. Through the biasing force applied by the bias spring 42, the built-in heat sink 41 can be moved along the up-down direction D2, and the heat coupling portion 411a of the built-in heat sink 41 can be elastically contacted with the pluggable module 300 inserted into the lower accommodation space 17 to ensure the integrity of the contact and enhance the heat dissipation performance.

[0112] Referring to Figures 3 to 7 , the rear end of the compartment bracket 31 is located in front of the front ends of the upper socket 211 and the lower socket 212, and the extension bracket 32 is assembled to the rear end of the compartment bracket 31. Specifically, in this embodiment, the extension bracket 32 is sleeved on the built-in heat sink 41 and is sleeved by the compartment bracket 31, and the compartment bracket 31 limits the movement of the extension bracket 32 in the up-down direction D2 and the left-right direction D3, so that the extension bracket 32 can be in a front position (see Figure 4 ) in front of the front ends of the upper socket 211 and the lower socket 212 relative to the compartment bracket 31, and a rear position (see Figure 6) move therebetween. Since in an assembly scenario, the socket connector 2 is first installed on the circuit board 200, and then the guiding shielding cover 1 provided with the partition frame 3 is covered on the socket connector 2 and fixed to the circuit board 200. Therefore, when the extension bracket 32 is located at the front position in front of the front ends of the upper socket 211 and the lower socket 212 of the socket connector 2, the extension bracket 32 can avoid the upper socket 211 of the socket connector 2 to prevent interference problems and affect the assembly. Moreover, after the assembly is completed, the extension bracket 32 can be moved backward to extend into the rear position between the upper socket 211 and the lower socket 212, so that the partition frame 3 can play a complete spacing role. Generally speaking, through the extension bracket 32 of the partition frame 3 that can move between the front position and the rear position, it is possible to avoid interference problems between the partition frame 3 and the socket connector 2 during the assembly process to facilitate the assembly operation on the premise that the partition frame 3 can play a complete spacing role subsequently.

[0113] Refer to Figures 4 to 7 , the extension bracket 32 has an upper wall 321 and a lower wall 322 that are opposite to each other up and down in this embodiment, and two side walls 323 connecting to the side edges of the upper wall 321 and the lower wall 322. The connector assembly 100 further includes a holding member. The extension bracket 32 has a first holding portion 323c that is snapped onto the holding member when in the front position, and a second holding portion 323d that is snapped onto the holding member when in the rear position. Specifically, the holding member is two elastic holding pieces 124 that are respectively formed on the two side walls 12 of the guiding shielding cover 1 and have inwardly recessed ends in this embodiment. It should be noted that the elastic holding pieces 124 (holding members) can also be formed on the two side walls 314 of the compartment bracket 31 in other embodiments, and this embodiment is not limiting. Each side wall 323 of the extension bracket 32 has a side plate 323a corresponding to and cooperating with the elastic holding piece 124, and a limiting hole 323b adjacent to the side plate 323a behind the side plate 323a. The front inner edge 323f of the limiting hole 323b and the rear edge 323g of the side plate 323a together form the first holding portion 323c, and the front edge 323h of the side plate 323a forms the second holding portion 323d.

[0114] Refer to Figure 5 , Figure 7 , Figure 8 and Figure 9, in addition, each side wall 12 of the guiding shield 1 further has a limiting piece 125 located behind the corresponding elastic holding piece 124 and recessed inward in a vertically folded manner to correspondingly extend into the limiting hole 323b. Each side wall 314 of the compartment bracket 31 has an avoidance opening 314a for the elastic holding piece 124 and the limiting piece 125 to pass through. Moreover, each of the two side walls 323 of the extension bracket 32 has a guiding piece 323e extending outward and bent upward. Each of the two side walls 314 of the compartment bracket 31 has a guiding piece receiving notch 314b located at the rear end and used for receiving the outwardly extending portion of the guiding piece 323e. Each of the two side walls 12 of the guiding shield 1 has a guiding rail groove 126, and the outwardly extending portion of the guiding piece 323e is slidably disposed in the guiding rail groove 126. In addition, the front end area of the guiding rail groove 126 is larger, so that the upwardly bent portion of the guiding piece 323e can correspondingly pass through during the assembly process.

[0115] Specifically, referring to Figures 4 to 6 , when the extension bracket 32 is in the front position, the elastic holding piece 124 (holding member) is clamped to the first holding portion 323c formed by the front inner edge 323f of the limiting hole 323b and the rear edge 323g of the side plate 323a. The limiting piece 125 abuts against the rear inner edge 323i of the limiting hole 323b, and the guiding piece 323e is received in the guiding piece receiving notch 314b and located at the front end of the guiding rail groove 126; referring to Figures 7 to 9 , when the extension bracket 32 moves from the front position to the rear position, the elastic holding piece 124 (holding member) crosses the side plate 323a and is clamped to the second holding portion 323d formed by the front edge 323h of the side plate 323a. The limiting piece 125 abuts against the front inner edge 323f of the limiting hole 323b, and the guiding piece 323e disengages from the guiding piece receiving notch 314b and moves to the rear end of the guiding rail groove 126. Through the corresponding clamping cooperation between the elastic holding piece 124 (holding member) and the first holding portion 323c and the second holding portion 323d, the extension bracket 32 can be positioned at the front position and the rear position, and through the corresponding cooperation between the limiting piece 125 and the limiting hole 323b and between the guiding piece 323e and the guiding rail groove 126, the extension bracket 32 can be sufficiently guided, limited, and supported.

[0116] Referring to Figures 4 to 7 , in addition, in this embodiment, the lower wall 312 of the compartment bracket 31 further forms a positioning structure 301c that bends downward and protrudes from the lower window 312a to extend into the lower accommodation space 17 and is used for positioning and guiding the pluggable module 300 (see Figure 1) The alignment portion 312b of ( ), the lower wall 322 of the extension bracket 32 has a lower stop portion 322a that extends into the lower accommodation space 17 and is used to stop against the alignment structure 301c of the pluggable module 300 to limit the insertion position of the pluggable module 300. When the extension bracket 32 is in the front position, the pluggable module 300 entering the lower accommodation space 17 can push against the lower stop portion 322a, causing the extension bracket 32 to move backward to the rear position. Thus, the pluggable module 300 that first enters the lower accommodation space 17 can use the lower stop portion 322a to push the extension bracket 32 backward to the rear position, eliminating the manual operation steps during assembly.

[0117] In summary, the connector assembly 100 of the present invention can avoid interference problems between the partition frame 3 and the socket connector 2 during the assembly process through the extension bracket 32 of the partition frame 3 that can move between the front position and the rear position, facilitating the assembly operation.
