A DC charging socket for pure electric vehicles

Abstract

The invention relates to a DC charging socket for a pure electric vehicle, and the socket is characterized in that the socket is provided with a national standard charging interface, a whole vehicle high-voltage interface and a whole vehicle low-voltage signal interface; the socket comprises a socket body, wherein one end of the socket body is connected with the national standard charging interface in a sealed mode, and the other end of the socket body is connected with a rear cover in a sealed mode; an integrated circuit board is arranged in the socket body, a low-voltage terminal is fixedly installed on the integrated circuit board, and a low-voltage signal plug-in is connected with a circuit on the integrated circuit board and extends out of the side wall of the socket body to form the low-voltage signal interface of the whole vehicle; one end of a high-voltage terminal is fixed in a high-voltage terminal mounting hole in the national standard charging interface, and the other end passes through the integrated circuit board to be connected with a high-voltage copper bar; the side wall of the side, close to the high-voltage terminal, of the socket body is provided with a high-voltage wire harness inlet and outlet so as to form the high-voltage interface of the whole vehicle, and the whole vehicle high-voltage interface is provided with a wire sealing tail cover.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to a DC charging socket for pure electric vehicles. Background technique [0002] Charging is an essential function of pure electric vehicles. As people's requirements for the charging time of pure electric vehicles increase, DC charging sockets are used more and more frequently, so DC charging sockets will be an essential component in pure electric vehicles. Since the pure electric vehicle DC charging socket belongs to the high-voltage electrical appliance of the automotive grade, and considering the ergonomics, the pure electric vehicle DC charging socket is generally installed on the front grille, rear side wall, etc. of the vehicle to facilitate people's use, but these places Generally, the space is small, which makes the design, integration and assembly of the vehicle very difficult. Therefore, the DC charging socket not only needs to have high p...
