An end-face contact charging and discharging connector

Abstract

The invention discloses an end face contact charge-discharge electrical connector. An existing end face contact electrical connector can have the phenomenon of arc discharge. The end face contact charge-discharge electrical connector comprises a socket and a plug; the socket comprises a base, a floating plate, elastomers, a cover board, guide sleeves, tower springs and moving contact assemblies; the floating plate is arranged in a floating plate mounting cavity; one elastomer is arranged in one elastomer mounting cavity; each moving contact assembly comprises a moving contact insulator, a moving contact, a pressure spring and a shaft retaining ring; a flange part of each moving contact insulator is connected with the floating plate by a bolt; one end of each moving contact is provided with a pressure spring mounting shaft; each pressure spring mounting shaft passes through a moving contact mounting hole of the corresponding moving contact insulator; the plug comprises a mounting panel and fixed contact assemblies; each fixed contact assembly comprises a fixed contact, a fixed contact front insulator and a fixed contact rear insulator; each guide pillar on the plug extends into the corresponding guide sleeve of the socket. According to the invention, the displacement compensation function and the angle compensation function can be implemented, and the arc discharge risk is reduced.

Description

technical field

[0001] The invention belongs to the technical field of vehicles, and relates to an electrical connector, in particular to a charge-discharge connector in which the power and signal mixed in the battery replacement mode of a new energy vehicle are contacted in an end-face contact mode. Background technique

[0002] At present, there are electrical connectors with end-face contact on the market that are used in new energy vehicles in the battery replacement mode for charging and discharging batteries. This connector is a charging and discharging connector. This charging and discharging connector is composed of a plurality of individual connectors and a mounting panel, the individual connectors are mounted on the mounting panel by screws, and the mounting panels are fixedly mounted on the battery box and the vehicle respectively. The charge-discharge connector that has been used will cause arcing during discharge, that is, during the operation of the vehicle, ca...
