Description

Technical Field

[0002] The traditional high-voltage connector of new energy vehicles consists of a connector socket and a connector plug that is plugged into the connector socket. Among them, the connector plug includes a plug housing, a power female terminal arranged in the plug housing through an insulating rubber core, and the power female terminal is usually a sheet-type female terminal. The traditional sheet-type female terminal adopts a stacked connection, and its structure includes: a sealed square socket, a copper busbar integrally formed at the rear end of the square socket, and a spring sheet arranged in the square socket, and the spring sheet is usually made of copper plate. Because the spring sheet is limited by its own material and the space of the square socket, it has poor tension and is easy to fatigue, which leads to the disadvantages of large resistance to plugging and unplugging in the early stage and easy loosening in the later plugging and unplugging. In addition, the traditional sheet-type female terminal also has the disadvantages of high processing cost and the copper busbar structure cannot be adjusted. Utility Model Content

[0012] The advantages of the sheet-type female terminal assembly of the utility model are as follows:

[0013] 1. Since the first plug-in surface and the second plug-in surface of the spring are both composed of a row of spaced elastic arms, the stress during plugging and unplugging is dispersed, and a stainless steel sheath is arranged outside the spring, and the clamping surface of the stainless steel sheath is clamped on the plug-in surface of the spring.
