Description

Technical Field

[0001] The utility model belongs to the field of new energy vehicles, and particularly relates to a DC charging socket for new energy vehicles. Background Art

[0002] An automotive charging socket is an interface on an electric vehicle for connecting a charger. Its structure includes: a mounting panel, a bushing provided at the rear end of the mounting panel, and a DC female terminal, a low-voltage auxiliary power terminal, and a signal terminal provided in the bushing. To achieve lightweight design and cost reduction of the automotive charging socket, an aluminum busbar is usually used for connection at the rear end of the DC female terminal. The disadvantages of the DC female terminal are as follows: 1. After the aluminum busbar is formed, its structural dimensions are relatively fixed, making it difficult to first connect to the charging socket and then install on the vehicle body; 2. If a flexible wire is used to connect the charging socket and the aluminum busbar, multiple welding or crimping operations cannot be avoided, reducing the connection reliability, increasing the resistivity, and posing a potential risk of increased temperature rise.
