[0013] Technical effects and advantages of the present invention:

[0014] 1. The present invention is provided with a joint heat dissipation device, and there is a thermoelectric conversion mechanism inside the joint heat dissipation device. When the resistance at the connector is too large and causes the temperature to rise, the heat will accumulate inside the wiring harness joint. The good thermal conductivity of the copper sheet is used to transfer the heat accumulated in the wiring harness joint to the hot end plate, so that the temperature of the hot end plate increases. When the temperature of the hot end plate is much higher than the temperature of the cold end plate, a potential difference is formed between the two, and the two are connected by a semiconductor. Electrons have the characteristic of flowing from high potential to low potential. Therefore, current is formed between the hot end plate and the cold end plate. When the current is transmitted to the motor by a wire, the motor drives the fan to blow the heat accumulated in the wiring harness joint to the outside to achieve the purpose of heat dissipation. This is conducive to solving the problem that the resistance at the wiring harness and the connector is too large, which may cause the temperature to rise, thereby causing aging and burning of the insulation layer, and improving the service life of the connecting harness.

The present invention is provided with a dustproof and waterproof device, which has a one-way tube assembly, one end of which faces the outside world and the other end faces the inside of the wiring harness connector. The inner wall of the one-way tube assembly is provided with a longitudinal filter screen and a transverse filter screen, which isolate most of the dust and water vapor outside the mesh surface; the one-way tube has a bundle pipe at one end close to the inside of the connector, which makes it difficult for dust to enter the pipe mouth and blocks a small part of the dust entering the filter screen; when the water vapor passes through the filter screen, it is easily liquefied into beads by the filter screen, and has a certain adhesion effect on the dust; in addition, the hot air formed by the connector heat dissipation device flows from the inner pipe mouth of the bundle pipe to blow the dust and water vapor in the one-way tube to the outside of the tube, which is conducive to solving the problem that the wiring harness and connector of the connecting wiring harness assembly for volt-energy storage are not waterproof and dustproof when used in outdoor environments, which causes moisture or dust to enter the inside of the wiring harness and cause electrical failures or short circuits, thereby improving the safety of the connecting wiring harness assembly and also improving the service life of the wiring harness assembly.

[0033] In this embodiment, it is necessary to specifically explain that there is a thermoelectric heat dissipation component 106 inside the connector heat dissipation device 1.

This is conducive to solving the problem that excessive resistance at the wiring harness and connector will cause temperature rise, and then cause aging and burning of the insulation layer, thereby improving the service life of the connecting harness.

[0034] Reference Figure 6 The dustproof and waterproof device 2 includes an outer shell 201, both sides of the outer shell 201 are fixedly connected with mounting plates 202, the front sides of the two mounting plates 202 are fixedly sleeved with one-way tube assemblies 203, and the back side of the outer shell 201 is electrically connected with a branch connection line 303.

The inner wall of the pipe shell 2031 is provided with a longitudinal filter screen and a transverse filter screen, which isolate most of the dust and water vapor outside the mesh surface. The end of the pipe shell 2031 close to the inside of the connector is provided with a bundle pipe 2034, and dust is difficult to enter the pipe opening, and a small part of the dust entering the filter screen is blocked.

In addition, the hot air formed by the connector heat dissipation device flows from the inner tube mouth of the bundle tube 2034, blowing the dust and water vapor in the tube shell 2031 to the outside of the tube, which is beneficial to solve the problem that the wiring harness and connector of the connecting harness assembly for volt-energy storage used in outdoor environments are not waterproof and dustproof enough, resulting in moisture or dust entering the interior of the wiring harness, causing electrical failure or short circuit, thereby improving the safety of the connecting harness assembly and also increasing the service life of the wiring harness assembly.

[0038] Working principle of the present invention:

[0039] There is a thermoelectric heat dissipation component 106 inside the connector heat dissipation device 1. When the resistance at the connector is too large and causes the temperature to rise, the heat will accumulate inside the wiring harness connector 101. The good thermal conductivity of the heated copper sheet 1062 is used to transfer the heat accumulated in the wiring harness connector 101 to the hot end plate 1061, so that the temperature of the hot end plate 1061 increases. When the temperature of the hot end plate 1061 is much higher than the temperature of the cold end plate 1064, a potential difference will be formed between the two, and the two are connected by a semiconductor block 1063. Electrons have the characteristic of flowing from a high potential to a low potential. Therefore, a current is formed between the hot end plate 1061 and the cold end plate 1064. The current is transferred to the motor 1067 by the conductor rod 1066. The motor 1067 drives the fan 1068 to blow the heat accumulated in the wiring harness connector 101 to the outside to achieve the purpose of heat dissipation. This is conducive to solving the problem that the resistance at the wiring harness and the connector is too large, which will cause the temperature to rise, thereby causing aging and burning of the insulation layer, and improving the service life of the connecting harness.

The inner wall of the tube shell 2031 is provided with a longitudinal filter screen and a transverse filter screen, which isolate most of the dust and water vapor outside the mesh surface. The tube shell 2031 has a bundle pipe 2034 at one end close to the inside of the connector, so that dust is difficult to enter the tube opening, and a small part of the dust entering the filter screen is blocked. When the water vapor passes through the transverse filter screen 2032 and the longitudinal filter screen 2033, it is easily liquefied into beads by the filter screen, and has a certain adhesion effect on the dust. In addition, the hot air formed by the connector heat dissipation device flows from the inner tube opening of the bundle pipe 2034 to blow the dust and water vapor in the tube shell 2031 to the outside of the tube, which is conducive to solving the problem that the wiring harness and connector used in the outdoor environment for the connection harness assembly for volt-energy storage have insufficient waterproof and dustproof performance, which causes moisture or dust to enter the inside of the wiring harness, causing electrical failure or short circuit, thereby improving the use safety of the connection harness assembly and also improving the service life of the wiring harness assembly.
