In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0023] As Figures 1 to 5 shown, the heat dissipation structure of the high-voltage plug-in connector for wire and cable in this embodiment includes a heat dissipation component 1. The heat dissipation component 1 is arranged on the male plug connector 2. A plug slot 3 is arranged on one side of the male plug connector 2. There are several heat dissipation components 1, and the heat dissipation components 1 are evenly distributed at equal intervals on the male plug connector 2 outside the plug slot 3. One end of the heat dissipation component 1 away from the plug slot 3 is arranged outside the male plug connector 2. A female plug connector 4 is arranged on one side of the male plug connector 2. A plug head 5 is arranged on one side of the female plug connector 4. The plug head 5 is inserted and removed in the plug slot 3. A connection mechanism is arranged between the male plug connector 2 and the female plug connector 4. Connection seats 6 are arranged at the ends of the male plug connector 2 and the female plug connector 4 that are away from each other. One end of the male plug connector 2 and the female plug connector 4 is connected to the cable 7 through the connection seat 6.

[0024] Specifically, the heat dissipation component 1 includes a first heat sink 11, a second heat sink 12, and a third heat sink 13. Inside the male connector 2 outside the insertion slot 3, there are several first heat sinks 11 and second heat sinks 12 evenly distributed at equal intervals. The first heat sinks 11 and the second heat sinks 12 are arranged at intervals one by one. At the end of the first heat sink 11 and the second heat sink 12 away from the insertion slot 3, there is a third heat sink 13. The third heat sink 13 is arranged outside the male connector 2. A heat dissipation channel 14 is formed between the third heat sink 13 and the outer surface of the male connector 2. The first heat sinks 11 and the second heat sinks 12 conduct and transfer the heat generated inside the inserted component outward. That is, the heat inside the inserted component is conducted and transferred outward through the first heat sinks 11 and the second heat sinks 12 to the third heat sink 13, and then dissipated to the external environment of the inserted component through the third heat sink 13.

[0025] Furthermore, the third heat sink 13 is arranged in a semi-circular structure, and the heat dissipation channel 14 is arranged as a semi-circular channel. There are several heat dissipation holes 15 on the third heat sink 13, so that the heat dissipation contact area on the inserted component is large, there is a heat dissipation flow space, and the air circulation conducts heat quickly.

[0026] Furthermore, an anti-interference layer 31 is arranged inside the insertion slot 3. A heat conduction layer 32 is arranged on the side of the anti-interference layer 31 close to the heat dissipation component 1. The side of the heat conduction layer 32 away from the anti-interference layer 31 is in close contact with the sides of the first heat sink 11 and the second heat sink 12 away from the third heat sink 13. The heat conduction layer 32 is arranged as a heat conduction sheet, and the anti-interference layer 31 is an electromagnetic shielding film. The electromagnetic shielding film includes a stacked insulating layer, a shielding layer, and a glue film layer. The insulating layer is arranged close to the insertion slot 3, the glue film is arranged close to the heat conduction layer 32, and the shielding layer is arranged between the glue film and the insulating layer. The glue film is arranged as a heat conductive silicone, which strengthens the anti-interference protection of the insertion inside the insertion slot 3, and the heat conduction layer 32 strengthens the heat conduction and heat dissipation performance of the insertion inside the insertion slot 3.

[0027] Furthermore, the first heat sink 11, the second heat sink 12, and the third heat sink 13 are integrally arranged in a U-shaped structure, and the structures of the first heat sink 11, the second heat sink 12, and the third heat sink 13 are stable, which is convenient for manufacturing and production.

[0028] Furthermore, the connection mechanism includes a clamping block 8 and a clamping groove 9. A clamping block 8 is arranged on the side of the male connector 2 away from the connection seat 6, and a clamping groove 9 is arranged on the side of the female connector 4 away from the connection seat 6. The clamping block 8 is clamped in the clamping groove 9, so that the female connector 4 and the male connector 2 are clamped during insertion, and the inserted component is inserted stably.

[0029] Even further, the connection seat 6 is arranged in a V-shaped structure, and there are evenly distributed heat dissipation small holes on the surface of the connection seat 6. The heat dissipation small holes do not affect the internal circuits of the connection seat 6, and the heat dissipation small holes increase the surface heat dissipation of the connection seat 6.

[0030] The usage method of this embodiment is as follows: The plug connector 5 on the female socket 4 is inserted into the socket groove 3 of the male socket 2, and the clamping block 8 on the male socket 2 is clamped into the clamping groove 9 of the female socket 4, so that the female socket 4 and the male socket 2 are clamped and inserted. Since a number of heat dissipation components 1 are evenly arranged at equal intervals on the male socket 2 outside the socket groove 3, the anti-interference layer 31 in the socket groove 3 provides anti-interference protection for the plug connector 5 during insertion. The heat conduction layer 32 provided by the heat conduction sheet conducts heat for the inserted connector during insertion. The first heat dissipation fin 11 and the second heat dissipation fin 12 cooperate with the heat conduction sheet to conduct the heat generated inside the inserted connector outward, that is, the heat inside the inserted connector is conducted outward through the heat conduction sheet, the first heat dissipation fin 11, and the second heat dissipation fin 12 to the third heat dissipation fin 13, and is dissipated to the external environment of the inserted connector through the third heat dissipation fin 13. Since the third heat dissipation fin 13 with a semi-circular structure between the first heat dissipation fin 11 and the second heat dissipation fin 12 is arranged outside the male socket 2, and a semi-circular heat dissipation channel 14 is formed between the third heat dissipation fin 13 and the male socket 2. Combined with the heat dissipation holes 15 provided on the third heat dissipation fin 13, the inserted connector has a large heat dissipation contact area, a heat dissipation circulation space, and fast air circulation and heat conduction, so the heat dissipation performance of the inserted connector is stronger.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
