Replaceable terminal assembly for liquid cooling charging gun

Abstract

The invention relates to the field of liquid cooling charging guns, in particular to a replaceable terminal assembly for a liquid cooling charging gun. The assembly comprises a terminal main body, a terminal column, a terminal insulation cap, a liquid cooling cable conductor, a cooling liquid pipe and a temperature sensor; the terminal main body and the terminal column are detachably connected together, the front end of the terminal column is connected with the terminal insulation cap, and the liquid cooling cable conductor, the cooling liquid pipe and the temperature sensor are installed on the terminal main body. The charging gun terminal can be subjected to liquid circulation cooling heat dissipation by adopting a liquid cooling technology, the current-carrying capacity of the charging gun terminal is improved, the charging current can be greatly improved, the charging time is shortened, and the quick charging requirement of a user is met. And when the charging gun terminal is polluted or worn, serious charging heating cannot be caused, so that the use risk of a user is greatly reduced. And when the charging gun terminal is damaged, the charging gun terminal can be quickly replaced, so that the operation and maintenance cost of the charging pile is greatly reduced.

Description

technical field [0001] The invention relates to the field of liquid-cooled charging guns, in particular to a replaceable terminal assembly for a liquid-cooled charging gun. Background technique [0002] The charging current that the existing electric vehicle charging gun can withstand is relatively small, which leads to the slow charging speed of the electric vehicle and cannot meet the needs of users for fast charging. Most charging guns do not have a cooling device. When the terminals of the charging gun are polluted or worn out, charging heating faults occur frequently, which increases the risk of users. Charging guns in public charging stations are frequently used and subjected to various violent operations by users, which greatly increases the risk of terminal damage and wear. When the charging gun terminal is accidentally damaged, or the terminal is severely worn at the end of the charging gun's life, the charging gun terminal cannot be replaced separately, and only t...

AI Technical Summary

Problems solved by technology

When the charging gun terminal is accidentally damaged, or the terminal is severely worn at the end of the charging gun's life, the charging gun terminal cannot be replaced separately, and only the entire charging gun product of the charging pile can be replaced, resulting in high operation and maintenance costs for the charging pile.
