Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a power supply control module. Background Technology

[0002] A track socket, also known as an electric track socket, mainly consists of two parts: an electric track and a socket adapter (socket module).

[0003] A socket adapter typically includes a housing and a power control module encapsulated within the housing. Since the housing is mostly a closed structure, its heat dissipation is poor, and it is prone to overheating after prolonged use. The heat generated cannot dissipate quickly, which can affect the electronic components on the power control module, affecting the lifespan of the electronic components and the overall stability, or even damaging the electronic components. Utility Model Content

[0004] The purpose of this invention is to provide a power supply control module with good heat dissipation.

[0005] To achieve the above objectives, the technical solution proposed by this utility model is as follows:

[0006] A power supply control module includes an input circuit board, an output circuit board, pin headers, an insulating pad, and a heat sink. The output circuit board is placed on the heat sink, and the input circuit board is electrically connected to the output circuit board via pin headers. The heat sink protrudes towards the output circuit board, forming a plurality of protrusions, and has a plurality of clearance holes for avoiding pins of plug-in components on the output circuit board. The insulating pad is disposed between the heat sink and the output circuit board, and the insulating pad has a first through hole for the pins of plug-in components on the output circuit board to pass through and a second through hole for the protrusions of the heat sink to pass through.

[0007] Preferably, the plug-in components on the input circuit board and the output circuit board are arranged in a staggered manner between the input circuit board and the output circuit board.

[0008] Preferably, the input circuit board, output circuit board, insulating pad, and heat sink have a central insertion hole for the housing boss to be inserted.

[0009] Preferably, the upper surface of the output circuit board is connected to an output interface, and the upper surface of the input circuit board is connected to an input spring pin.

[0010] Preferably, the output circuit board includes a main body and two ears that protrude outward from the left and right sides of the main body and extend beyond the input circuit board. Each of the two ears is provided with a first socket for a screw to pass through.

[0011] Preferably, the heat sink includes a base plate, two support plates protruding upward from the left and right sides of the base plate, and several side baffles bent upward from the periphery of the base plate. The output circuit board is placed on the support plates, and the support plates have a second socket corresponding to the position of the first socket.

[0012] Preferably, the heat sink further includes a plug plate bent upwards from both sides of the base plate, and the insulating pad is provided with a third insertion hole that engages with the plug plate.

[0013] The beneficial effects of this utility model by adopting the above technical solution are as follows: This utility model achieves overall board cooling by adding a heat sink below the output circuit board. An insulating pad is placed between the output circuit board and the heat sink to insulate the electronic components on the output circuit board from the heat sink. The heat sink protrudes upward to form several protrusions that pass through the insulating pad, which can increase the heat dissipation contact area and thus improve the heat dissipation efficiency. At the same time, several clearance holes are opened on the heat sink to avoid the pins of plug-in components on the output circuit board. While reducing the distance between the heat sink and the output circuit board and improving the heat dissipation efficiency, it also avoids electrical short circuits. Attached Figure Description

[0020] like Figures 1-3 As shown, the power supply control module of this embodiment includes an input circuit board 1, an output circuit board 2, pin headers 3, an insulating pad 4, and a heat sink 5. The input circuit board 1 is fixed above the output circuit board 2 via the pin headers 3, and is also electrically connected to the output circuit board 2 via the pin headers 3. A heat sink 5 is provided below the output circuit board 2 for its support. The heat sink 5 protrudes towards the output circuit board 2, forming several protrusions 6 to increase the heat dissipation contact area. The heat sink 5 has clearance holes 7 to avoid the pins of plug-in components on the output circuit board 2. The clearance holes 7 help to reduce the distance between the heat sink 5 and the output circuit board 2, improve heat dissipation efficiency, and prevent electrical short circuits. The insulating pad 4 is located between the heat sink 5 and the output circuit board 2, and has a first through hole 8 for the pins of plug-in components on the output circuit board 2 to pass through and a second through hole 9 for the protrusions 6 of the heat sink 5 to pass through.

[0021] To achieve miniaturization of the socket adapter, the plug-in components on the input circuit board 1 and the output circuit board 2 in this embodiment are staggered between the input circuit board 1 and the output circuit board 2 to make full use of the space between them, making the power supply control module structure more compact, and also helping to protect these plug-in components.

[0022] In this embodiment, the output circuit board 2 has an output interface 11 inserted into its upper surface. To facilitate the assembly of the socket adapter on the power rail, an output spring pin is inserted into the upper surface of the input circuit board 1 for electrical connection with the power rail to draw power.

[0023] To facilitate the assembly of the power supply control module in this embodiment within the housing, a central socket 10 is provided on the input circuit board 1, output circuit board 2, heat sink 5, and insulating pad 4 for the housing boss to be inserted.

[0024] The output circuit board 2 includes a main body 13, with ears 14 protruding outward from both sides of the main body 13. The ears 14 extend beyond the input circuit board 1 and have a first jack hole 15 for screws to pass through.

[0025] Correspondingly, the heat sink 5 in this embodiment includes a base plate 16, support plates 17 protruding upwards from the left and right sides of the base plate 16, several side baffles 18 bent upwards from the periphery of the base plate 16, and insert plates 20 bent upwards from both sides of the base plate 16. The output circuit board 2 is placed on the support plate 17 to create a certain gap between the output circuit board 2 and the base plate 16, which facilitates heat dissipation. The support plate 17 has a second socket 19 corresponding to the position of the first socket 15. The first socket 15 and the second socket 19 are used to fix the power supply control module inside the housing with screws. The side baffles 18 limit the output circuit board 2 and also provide some protection.

[0026] The insulating pad 4 is provided with a third insertion hole 21 that mates with the insertion plate 20 to limit the insulating pad 4 onto the heat sink 5.
