[0002] With the rapid development of LED technology, LED automotive lights have been widely used in various automotive lighting systems due to their advantages such as high brightness, low energy consumption, and long lifespan. LED automotive lights are typically electrically connected to the vehicle's wiring harness via connectors, which generate a certain amount of heat during operation. If this heat cannot be dissipated in time, it can cause the connectors and surrounding components to overheat, affecting not only the stability and safety of the electrical connection but also potentially accelerating component aging and reducing the overall lifespan of the automotive lights.

[0003] Currently, common LED automotive lamp connectors rely on natural heat dissipation or simple metal heat-conducting structures for heat dissipation, resulting in limited efficiency and failing to meet the long-term heat dissipation requirements of high-power LED automotive lamps. Furthermore, existing connector mounting structures often lack sufficient sealing, allowing dust, moisture, and other external impurities to enter, affecting insulation performance. They also suffer from unclear heat dissipation paths and inadequate balance between heat conduction medium and electrical isolation. Therefore, designing a heat dissipation structure for LED automotive lamp connectors that offers high heat dissipation efficiency, good sealing, convenient installation and maintenance, and effective isolation of electrical components has become a pressing technical challenge in this field.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] In one embodiment, see [reference] Figures 1 to 8 A heat dissipation structure for an LED vehicle light connector includes a heat-conducting plate 1, a heat dissipation component mounted on the top of the heat-conducting plate 1, and a connector mounting component mounted on the bottom of the heat-conducting plate 1. The heat-conducting plate 1 is fixedly connected to two sides of the fixing base 2. The present invention uses the fixing base 2 to stably install and fix the equipment. The connector mounting assembly includes a connector mounting groove 3 fixedly connected to the bottom of the heat-conducting plate 1. A sealing cover 4 is provided at the bottom of the connector mounting groove 3. The sealing cover 4 and the connector mounting groove 3 are slidably sealed together by a sealing cylinder 5. Semi-circular wiring pipes 9 are installed on both sides of the connector mounting groove 3 and the sealing cover 4. Two sets of wiring pipes 9 on the same side cooperate with each other. A rubber sealing ring 11 is provided inside the inner wall of the wiring pipe 9. The connector is installed in the connector mounting slot 3, and the wire harness passes through the rubber sealing ring 11 and is connected to the connector. The connector mounting slot 3 and the sealing cover 4 are filled with insulating and thermally conductive adhesive. This invention first involves placing a connector with a wire harness into the connector mounting slot 3. Then, rubber sealing rings 11 are wrapped around the wire harness on both sides of the connector, and the rubber sealing rings 11 are placed into the wiring tube 9. The sealing cover 4 is then closed to fix the wire harness in the wiring tube 9. Sufficient insulating thermally conductive adhesive is then injected into the connector mounting slot 3 and the sealing cover 4. When current flows through the wire harness, the connector generates heat, which is transferred to the heat-conducting plate 1 through the insulating thermally conductive adhesive. The heat is then absorbed by the heat dissipation component and dissipated quickly.

[0023] In one instance of this embodiment, please refer to Figures 1 to 8 Limiting blocks 10 are provided at both ends of the inner wall of the wiring pipe 9, and the rubber sealing ring 11 is disposed between the two sets of limiting blocks 10. The present invention uses the limiting blocks 10 to limit and fix the rubber sealing ring 11, thereby preventing the rubber sealing ring 11 from sliding out of the wiring pipe 9.

[0024] In one instance of this embodiment, please refer to Figures 1 to 8 The connector mounting groove 3 is provided with threaded cylinders 6 fixedly connected to the bottom of the heat conduction plate 1 on both sides. The sealing cover 4 is fixedly connected with connecting seats 7 on both sides. Connecting screws 8 are provided in the connecting seats 7 and are threaded through the connecting seats 7 and connected to the threaded cylinders 6. This utility model achieves a stable connection between the connecting seat 7 and the threaded cylinder 6 by setting the connecting screw 8, thereby realizing the stable installation and fixation of the sealing cover 4.

[0025] In one instance of this embodiment, please refer to Figures 1 to 8 The bottom of the sealing cover 4 is provided with a glue injection port 12, and a protective cover 13 is connected to the glue injection port 12 by internal thread. The present invention uses the glue injection port 12 to inject insulating and thermally conductive glue into the connector mounting groove 3 and the sealing cover 4, and uses the protective cover 13 to protect and seal the glue injection port 12.

[0026] In one instance of this embodiment, please refer to Figures 1 to 8 The heat dissipation assembly includes a heat-conducting cylinder 14 fixedly connected to the top of the heat-conducting plate 1. Heat dissipation fins 15 are fixedly connected to the outer wall of the heat-conducting cylinder 14. A mounting groove 16 is provided on the outer wall of the heat dissipation fins 15. A mounting bracket 17 is provided on the top of the heat dissipation fins 15. Hooks 18 are fixedly connected to both sides of the mounting bracket 17. The hooks 18 cooperate with the mounting groove 16. A mounting base 19 is fixedly connected to the top of the mounting bracket 17. A motor 20 is fixedly connected to the mounting base 19. A fan blade 21 is fixedly connected to the output shaft of the motor 20. The heat dissipation assembly first achieves a stable connection between the heat dissipation fins 15 and the mounting bracket 17 through the cooperation of the hook 18 and the mounting slot 16. Then, during the operation of the equipment, the heat is first absorbed by the heat conduction cylinder 14, and then the heat is absorbed by the heat dissipation fins 15. The fan blades 21 are then driven to rotate by the motor 20, and the rotation of the fan blades 21 accelerates the flow of gas in the heat dissipation fins 15, thereby increasing the heat dissipation efficiency of the heat dissipation fins 15.
