Abstract

The invention relates to a graphene material-based charging gun structure, which comprises a charging gun body, a charging connector arranged at the front end of the charging gun body, and a charging wire connected with the rear side end of the charging gun body, a charging hole is arranged in the charging connector, and the inner wall of the charging hole is nested and matched with a cage type girdle sleeve made of a graphene metal material; and the charging wire is a litz wire made of a graphene metal material, and is formed by twisting or weaving and shaping a plurality of litz wires. According to the invention, the cage type girdle sleeve made of a graphene metal material is additionally arranged in a traditional charging gun structure, so that the conductivity is improved, and the heat dissipation at the charging connector is improved; and meanwhile, the charging wire is also a litz wire made of a graphene metal material, the litz wire has consistent wire winding and arranging performance, the heat dissipation of the charging wire is further improved through the graphene material, and the situation that the use safety is affected due to the fact that the temperature of the charging gun is obviously increased in the use process is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of charging guns, in particular to a graphene material-based charging gun structure. Background technique [0002] Based on the continuous development of new energy sources, in the field of pure electric vehicle fast charging, under the condition of high current, the heat generated by the entire connector will cause the temperature of the entire connector system to rise, and the temperature rise will significantly affect the performance of the connector; for For high-current connectors, the temperature rise effect is a key performance that must be considered; in the actual application process, the heat density comes from the parts of the male and female connectors and the live cables, and there are two parts with the highest heat density: the First, the contact point of the contact pair; second, the crimping point between the terminal and the cable; therefore, for the charging gun used in the field of pure e...
