Description

Technical Field

[0001] The present invention relates to the technical field of terminal burn-proof guns for direct current liquid-cooled charging guns, and in particular to a charging gun terminal burn-proof gun device and a charging gun. Background Art

[0002] At present, charging gun manufacturers all make them according to the national standards. However, in actual use, the charging gun may jump due to the heating of the DC+ / DC- terminal, and the wire core may deform due to long-term high-temperature use. The conventional terminal length on the current market is 55MM, and the conductor copper wire deforms in about a year. The bracket is made of heterothermal nylon and is a solid heat absorber. This situation brings inconvenience to the end user and the charging gun, and there are safety hazards such as burning the gun, burning the pile, burning the car, and injuring people. Therefore, the present invention proposes a charging gun terminal anti-burning gun device and a charging gun, so as to solve the safety hazards of charging gun heating, jumping the gun, injuring people, burning the gun, burning the pile, and burning the car. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a charging gun terminal burn-out prevention device and a charging gun to prevent the DC+ / DC- terminal from heating up and causing the gun to jump, and the wire core from deforming due to long-term high-temperature use; at the same time, it increases the safety of use and service life.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a charging gun terminal anti-burn gun device, comprising a first terminal bracket, a second terminal bracket is provided on the top of the first terminal bracket, two terminal entities are provided in the inner cavity of the second terminal bracket, and the tops of the terminal entities are fixedly connected with terminal bodies.

[0005] Preferably, the terminal body is lengthened by 58 mm, with a total length of 113 mm, and the terminal entity length is 60 mm.

[0006] Preferably, the terminal body is tightly matched with the heat dissipation nylon to conduct the temperature on the terminal body.

[0007] Preferably, the first terminal bracket and the second terminal bracket are made of thermally conductive nylon, and the thermally conductive nylon absorbs and conducts the temperature of the terminal body.

[0008] Preferably, the diameter of the terminal entity is increased to 22 mm.

[0009] Preferably, the terminal crimping length is extended from the original 10 mm to 15 mm, thereby increasing the crimping area.

[0010] The present invention provides another technical solution: a charging gun, comprising the charging gun terminal burn-proof device as described above.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention changes the DC+ / DC- terminal structure, uses thermal conductive materials for the internal bracket, and expands the area of ​​heat absorption and heat dissipation of the product. A new structure is also designed for the DC power terminal, which is lengthened from 55mm to 113MM in the length of the conventional terminal body on the market, and the terminal entity diameter is increased to 22mm, which effectively protects the cable conductor and solves the problem of charging gun heating and jumping, and extends the normal service life of the charging gun. When the heat source is conducted from the terminal head to the terminal tail, it is absorbed by the lengthened terminal entity and absorbed by the tight-fitting thermal conductive material and then conducted to the surface of the gun body for heat dissipation, thereby reducing the temperature inside the product itself, and the cable is reduced from 80 square meters to 70 square meters, saving the overall cost of the charging gun.
