[0055] The M.2 connector is a crucial component in modern computer systems, widely used in key scenarios for expanding and upgrading computer performance. It plays an irreplaceable role in the continuous development of computer hardware, mainly used to connect electronic cards such as solid-state drives, Bluetooth modules, and WiFi modules to improve computer performance.

[0056] With the increase in data transfer speed, the heat generated by hard drives during operation increases dramatically. Heat accumulation can affect the performance and stability of hard drives, so it is necessary to cool down solid-state drives in a timely manner. This is usually done by installing a heatsink on the connector. Typically, the heatsink needs to be secured with screws. The two ends of the heatsink are fixed to the connector and the PCB board, respectively. The installation process is cumbersome and inconvenient to disassemble, which increases the time cost.

[0057] This utility model proposes a connector assembly.

[0058] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the connector assembly includes:

[0059] Connector body 100, connector body 100 has a plug interface for inserting electronic card 110;

[0060] The mounting frame 200 is at least partially fitted onto the outside of the connector body 100, with the insertion interface exposed on the surface of the mounting frame 200.

[0061] Circuit board 600, connector body 100 and circuit board 600 are electrically connected, and mounting frame 200 and circuit board 600 are fixedly connected;

[0062] The heat sink module 300 is mounted on the mounting frame 200 and attached to the electronic card 110;

[0063] The drive module 400 is slidably connected to the heat sink module 300; and

[0064] The snap-fit ​​structure 500 includes a snap-fit ​​part 510 disposed on the mounting frame 200 and a snap-fit ​​groove 520 disposed on the drive module 400. By sliding the drive module 400, the snap-fit ​​part 510 has a locked state in which it is connected and fixed to the snap-fit ​​groove 520 and a released state in which it is separated from the snap-fit ​​groove 520.

[0065] The snap-fit ​​part 510 is integrally formed with the mounting frame 200.

[0066] In the technical solution of this utility model, the connector assembly includes a circuit board 600, a connector body 100 disposed on the circuit board 600, and a mounting frame 200 sleeved on the connector body 100. An electronic card 110 is inserted into the connector body 100 and extends along a first direction. A heat sink module 300 is disposed above the electronic card 110 and fits against the electronic card 110 to effectively dissipate heat from the electronic card 110. The end of the heat sink module 300 is disposed on the mounting frame 200 and is detachably connected to the mounting frame 200 by a snap-fit ​​structure 500, which enables quick disassembly of the heat sink module 300, facilitates maintenance of the electronic card 110 or replacement of the heat sink module 300, and improves the reliability and stability of the electronic equipment.

[0067] Specifically, the connector assembly includes a connector body 100, which includes a plastic body and a conductive terminal group. The plastic body is made of a plastic material with good insulation properties. The bottom of the plastic body is mounted on a circuit board 600. A lower slot and an upper slot are respectively provided on the front and rear sides of the plastic body, and an insertion interface is provided on the upper front side of the plastic body for inserting an electronic card 110. The electronic card 110 is commonly used for data storage, communication, or identity recognition, such as an SD card or a CF card. The lower slot and the upper slot are respectively connected to the insertion interface. The conductive terminal group includes an upper terminal and a lower terminal. The upper terminal is inserted into the upper slot from the rear side of the plastic body, and the lower terminal is inserted into the lower slot from the front side of the plastic body. Both the upper terminal and the lower terminal are exposed at the insertion interface to conduct electricity with the inserted electronic card 110. The bottom of the upper terminal and the lower terminal are soldered to the circuit board 600.

[0068] Please refer to Figure 11The mounting frame 200 is fitted onto the plastic body, and the insertion interface is exposed on the mounting frame 200 so that the electronic card 110 can be exposed on the mounting frame 200. The bottom of the mounting frame 200 is soldered to the circuit board 600, and the mounting frame 200 is preferably made of metal, such as alloy or stainless steel, without limitation. The mounting frame 200 can provide stable support for the heat sink module 300. In one embodiment, the mounting frame 200 includes a top plate 210, side plates 220, and a rear plate 230. The top plate 210 is located on the top of the connector body 100. Two side plates 220 are provided, one on each side of the connector body 100. The rear plate 230 is located on the side of the connector body 100 away from the electronic card 110. Support feet 240 are provided on the side of the top plate 210, side plates 220, and rear plate 230 facing the circuit board 600. The support feet 240 are soldered to the circuit board 600. The top plate 210, side plates 220, and rear plate 230 form a semi-enclosed structure, which includes the rear area of ​​the connector. In one embodiment, the top plate 210 and the top of the connector body 100, the side plates 220 and the sides of the connector body 100, and the rear plate 230 and the side of the connector body 100 away from the electronic card 110 are all spaced apart, which can achieve a certain electromagnetic shielding effect and reduce interference with the electromagnetic performance of the connector body 100.

[0069] The heat sink module 300 is attached to the electronic card 110 and is made of a metal with good thermal conductivity, such as aluminum alloy. Its surface is tightly attached to the electronic card 110 to increase the contact area between the electronic card 110 and the air, so as to achieve good heat dissipation efficiency. The heat sink module 300 can be a metal plate with multiple protrusions spaced apart on the metal plate to increase the contact area with the air, ensure good heat dissipation effect, effectively reduce the temperature of the electronic card 110, avoid performance degradation due to overheating, and improve the reliability of electronic equipment operation.

[0070] Please refer to Figure 3 and Figure 4 A snap-fit ​​structure 500 is disposed between the radiator module 300 and the mounting frame 200. The snap-fit ​​structure 500 can use a combination of snap-fit ​​protrusions and snap-fit ​​holes. For example, a snap-fit ​​hole is provided at the end of the radiator module 300, and a spring connects the snap-fit ​​protrusion on the mounting frame 200. When the radiator module 300 is installed on the mounting frame 200, the spring causes the snap-fit ​​protrusion to snap into the snap-fit ​​hole, firmly installing the radiator module 300 on the mounting frame 200. This allows for quick connection between the radiator module 300 and the mounting frame 200, preventing detachment due to vibration, and also allows for quick release of the radiator module 300, enabling rapid installation and removal of the radiator module 300.

[0071] In one embodiment, the snap-fit ​​structure 500 includes a snap-fit ​​groove 520 and a snap-fit ​​portion 510. A snap-fit ​​groove 520 is provided on the drive module 400, and a snap-fit ​​portion 510 is provided on the top of the mounting frame 200. The heat sink module 300 and the drive module 400 are mounted on the mounting frame 200 from top to bottom. When the drive module 400 slides along the heat sink module 300, the snap-fit ​​portion 510 has a locked state and a released state. In the locked state, the snap-fit ​​portion 510 engages with the snap-fit ​​groove 520, thereby attaching the heat sink module 300 to the electronic card 110. In the released state, the latching part 510 and the latching slot 520 are in a detachable state. At this time, the drive module 400 and the heat sink module 300 can be moved upward from the mounting frame 200 to achieve the detachment of the heat sink module 300 from the electronic card 110. In other words, by sliding the drive module 400, the heat sink module 300 and the electronic card 110 can be quickly installed and detached, which is convenient for disassembly, maintenance and replacement, and improves work efficiency. Moreover, the latching part 510 and the mounting frame 200 are integrally formed, which makes the mounting frame 200 more stable when latched with the drive module 400.

[0072] In an embodiment of this utility model, the drive module 400 includes:

[0073] Mounting plate 410 is disposed between radiator module 300 and mounting frame 200 and is slidably connected to radiator module 300. Snap-fit ​​groove 520 is disposed on mounting plate 410 and extends along the first direction.

[0074] Push plate 420 is disposed on one side of mounting plate 410 and spaced apart from heat sink module 300 along the first direction;

[0075] An elastic element is provided between the push plate 420 and the heat sink module 300. The elastic element elastically connects the push plate 420 and the heat sink module 300. When the elastic element is in a compressed state, the push plate 420 tends to move away from the heat sink module 300.

[0076] Please refer to Figure 3 , Figure 4 and Figure 9The drive module 400 includes a mounting plate 410 disposed between the heat sink module 300 and the mounting frame 200. A snap-fit ​​groove 520 is provided on the mounting plate 410. A push plate 420 is provided on one side of the mounting plate 410, extending vertically upwards. An elastic element is provided between the push plate 420 and the heat sink module 300, and the arrangement direction between the push plate 420 and the heat sink module 300 is the extending direction of the snap-fit ​​groove 520. When the push plate 420 is pushed towards the heat sink module 300 in the first direction, the snap-fit ​​groove 520 and the snap-fit ​​part 510 correspond vertically, allowing the drive module 400 and the heat sink module 300 to be lifted upwards. When mounting the radiator module 300 and the drive module 400 onto the mounting frame 200, pressing the push plate 420 causes the snap-fit ​​groove 520 to align with the snap-fit ​​part 510, and then downwards, so that the snap-fit ​​part 510 is within the snap-fit ​​groove 520. Releasing the push plate 420 causes the elastic element to spring back, driving the push plate 420 to move away from the radiator module 300 and causing the mounting plate 410 to move along the first direction. At this point, the snap-fit ​​groove 520 and the snap-fit ​​part 510 are misaligned, allowing the snap-fit ​​part 510 to engage with the snap-fit ​​groove 520. In other words, by pressing the push plate 420 along the first direction, the radiator module 300 and the mounting frame 200 can be quickly installed and disassembled. In one embodiment, the elastic element can be a spring, but is not limited to a spring-like elastic structure; no limitation is imposed here.

[0077] In one embodiment, the bottom of the heat sink module 300 is provided with a mounting hole 320. When in the locked state, the snap-fit ​​part 510 snaps into the snap-fit ​​groove 520 and protrudes from the snap-fit ​​groove 520. The protruding part is located inside the mounting hole 320. That is, when in the released state, the snap-fit ​​part 510, the snap-fit ​​groove 520 and the mounting hole 320 are aligned in the vertical direction.

[0078] In an embodiment of this utility model, the snap-fit ​​portion 510 includes:

[0079] An upright plate 511 is provided on the mounting frame 200 and extends along a second direction;

[0080] A limiting plate 512 is provided at one end of the upright plate 511 away from the mounting frame 200, and the side of the limiting plate 512 away from the push plate 420 protrudes from the upright plate 511 to form a snap-fit ​​position, so that in the locked state, the snap-fit ​​groove 520 snaps into the snap-fit ​​position to prevent the mounting plate 410 from disengaging from the mounting frame 200 in the second direction.

[0081] Please refer to Figure 9 and Figure 11The snap-fit ​​part 510 includes a vertical plate 511 vertically disposed on the top of the mounting frame 200, and the vertical plate 511 extends in the vertical direction. A limiting plate 512 is disposed on the top of the vertical plate 511. The limiting plate 512 protrudes from the vertical plate 511 on the side away from the push plate 420 in the first direction, and the protruding part forms a snap-fit ​​position. In the locked state, the snap-fit ​​part 510 passes through the snap-fit ​​groove 520. The elastic element drives the mounting plate 410 and the push plate 420 to move away from the snap-fit ​​position, so that the snap-fit ​​position snaps with the snap-fit ​​groove 520, thereby restricting the mounting plate 410 from disengaging from the mounting frame 200 in the vertical direction. When it is necessary to disassemble the heat sink module 300, the push plate 420 is pressed, so that the mounting plate 410 moves in the first direction, that is, the horizontal direction, toward the snap-fit ​​position. The snap-fit ​​position can correspond exactly to the snap-fit ​​groove 520, so that the snap-fit ​​part 510 and the snap-fit ​​groove 520 can disengage in the vertical direction. The structure of the snap-fit ​​part 510 is simple and easy to manufacture.

[0082] In an embodiment of this utility model, the mounting plate 410 is provided with an elongated hole 411, the long axis of which extends along a first direction. The drive module 400 also includes a connector 450, which passes through the elongated hole 411 and is connected to the heat sink module 300. The connector 450 slides relative to the long axis of the elongated hole 411.

[0083] Please refer to Figure 9 The mounting plate 410 has at least one elongated hole 411 with a vertical major axis and a minor axis. The major axis extends along a first direction. A connector 450 passes through the elongated hole 411 from bottom to top and is fixedly connected to the heat sink module 300. Since the size of the elongated hole 411 is larger than that of the connector 450, the connector 450 can slide relative to the elongated hole 411. The arrangement of the elongated hole 411 and the connector 450 allows the drive module 400 to slide along the heat sink module 300 while ensuring that the heat sink module 300 and the drive module 400 are always connected, i.e., they are a single unit that can be simultaneously mounted on the mounting frame 200 and simultaneously detached from the mounting frame 200. In one embodiment, the connector 450 is a bolt. The bolt allows the heat sink module 300 and the drive module 400 to be detached, facilitating the replacement of the heat sink module 300.

[0084] In an embodiment of this utility model, the drive module 400 further includes a support plate 430, which is installed on the side of the push plate 420 away from the mounting plate 410 and extends along a first direction. The support plate 430, the push plate 420 and the mounting plate 410 together form a movable cavity, and the end of the radiator module 300 is movably disposed in the movable cavity.

[0085] Please refer to Figure 5 and Figure 9A support plate 430 is provided above the push plate 420. The support plate 430 is opposite to the mounting plate 410. The support plate 430 extends along the first direction and can cover one end of the heat sink module 300 and the top of the push plate 420. This makes the movement of the push plate 420 more stable and can also prevent the operator from being scratched when pushing due to the exposed ends of the push plate 420 and the heat sink module 300.

[0086] In an embodiment of this utility model, the heat sink module 300 is provided with a mounting groove 310 at one end near the mounting frame 200. The mounting groove 310 extends along a first direction. The push plate 420 is provided with a through hole. A pressure plate 440 is provided at the through hole. One end of the pressure plate 440 is bent and connected to the mounting plate 410. The two ends of the elastic member are respectively connected to the inner wall of the pressure plate 440 and the mounting groove 310.

[0087] Please refer to Figure 6 and Figure 8 A mounting groove 310 is provided at one end of the radiator module 300 near the drive module 400, and the mounting groove 310 extends along a first direction. An elastic element is installed in the mounting groove 310, with one end elastically connected to the inner wall of the mounting groove 310 and the other end extending along the first direction. A through hole is provided between the push plates 420, and a pressure plate 440 is provided in the movable cavity. The bottom of the pressure plate 440 is bent and connected to the mounting plate 410. The end of the elastic element away from the inner wall of the mounting groove 310 is elastically connected to the pressure plate 440. That is, when the drive module 400 is pushed, the pressure plate 440 can be pushed directly, so that the pressure plate 440 moves toward the radiator module 300, and also drives the snap-fit ​​groove 520 to move. The through hole and the mounting groove 310 can reduce the weight of the drive module 400 and the radiator module 300, which is beneficial to the lightweighting of the equipment.

[0088] In an embodiment of this utility model, the end of the electronic card 110 away from the connector body 100 is fixed to the circuit board 600 by a fastener 120, and the end of the heat sink module 300 away from the connector body 100 is also slidably provided with a drive module 400, which cooperates with the fastener 120 to have a locked state and a released state.

[0089] The two drive modules 400 are positioned relative to each other.

[0090] Please refer to Figure 5 , Figure 7 and Figure 10The electronic card 110 includes a card body and a storage chip. The chip makes contact with the conductive terminal group for electrical connection. A fastener 120 passes through the card body from top to bottom and connects to the bottom circuit board 600 to prevent the electronic card 110 from loosening within the connector body 100, ensuring a tight connection between the electronic card 110 and the connector body 100. The fastener 120 also forms a stable integrated structure between the electronic card 110, the connector body 100, and the circuit board 600, helping to improve overall mechanical strength and ensuring good electrical contact between the electronic card 110 and the connector. The fastener 120 is a bolt. Figure 10 As shown, a drive module 400 is also slidably disposed at the end of the heat sink module 300 away from the connector body 100. The drive module 400 is provided with a corresponding snap-fit ​​groove 520 to engage with the fastener 120.
