a high voltage connector

Abstract

The invention belongs to the technical field of new energy vehicle connectors, A high voltage connector comprising a plug and a socket, The plug comprises an insulating head and a socket assembly installed on the insulating head. The socket comprises an insulating seat and an insert piece fixed on the insulating seat. The socket further comprises a plastic shell arranged on opposite sides of the insert piece and a protective plate arranged between two plastic shells. The inner side of the plastic shell is provided with a card slot. The plug also comprises a rubber core arranged on both sides of the jack assembly. When the plug is inserted into the socket, the rubber core can expand the plastic shell and drive the protective plate to move along the insertion piece, so that the insertion piece is exposed from the upper end of the protective plate and inserted into the jack assembly. When the plastic shell is in a natural state, the protective plate is stuck in the card slot, and when theprotective plate is touched by hand, the protective plate does not move downward, and plays the function of tentacle protection safely and effectively.

Description

technical field [0001] The invention relates to the technical field of connectors for new energy vehicles, in particular to a high-voltage connector. Background technique [0002] In new energy electric vehicles, the main power transmission from the DC charging port of the electric vehicle to the battery, from the battery to the power distribution box, and from the power distribution box to the electric control is realized through high-voltage connectors. In order to ensure the safety of the connection and avoid electric shock, the connector usually takes certain protective measures. [0003] figure 1 Shown is a schematic structural diagram of an existing high-voltage connector socket, which includes an insulating seat 1', an insert 2' and an insulating shell 3', wherein the insert 2' is arranged on the insulating seat 1' and is connected to the insulating seat 1'. The wire connection is used for power transmission; the insulating shell 3' is arranged on the periphery of t...

AI Technical Summary

Problems solved by technology

[0004] 1. There is a large space in the insulating shell 3', and the tentacles of the insert 2' are prone to occur, resulting in failure of the tentacles protection

[0005] 2. The realization of the tentacle protection function is mainly guaranteed by the dimension H between the top of the insulating shell 3' and the top of the insert 2'. If effective protection is to be carried out, the dimension H needs to be increased, resulting in an increase in the size of the product in space
