Charging gun having good heat conduction and heat dissipation performances

Abstract

The invention relates to a charging gun having good heat conduction and heat dissipation performances. The charging gun comprises a gun body, a terminal, an insulated sleeve and a metal heat-dissipation part; the rear end part of the terminal is arranged on the sleeve in a penetrating manner; an installation hole used for fixing the sleeve in a penetrating manner is arranged on the metal heat-dissipation part; and the heat-dissipation part is fixed on the gun body. Compared with the prior art, the charging gun having good heat conduction and heat dissipation performances disclosed by the invention has the advantages that: because the metal heat-dissipation part is used as the main body for fixing the terminal and the metal heat-dissipation part and the terminal are separated by the insulated sleeve, short-circuiting is avoided; the traditional large ceramic part for fixing the terminal is eliminated; the easy breaking problem due to trepanning on the large ceramic part is avoided; bothprocesses of processing the sleeve and forming the installation hole on the metal heat-dissipation part are relatively convenient and low in processing difficulty; more importantly, the heat dissipation performance of metal is good; the metal heat-dissipation part is used as the main body for fixing the terminal; therefore, the heat dissipation effect is greatly improved; and relatively high heatdissipation requirements of the charging gun can be satisfied.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging gun with good heat conduction and heat dissipation performance. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Because electric vehicles have less impact on the environment than traditional vehicles, their prospects are widely optimistic. In recent years, the penetration rate of electric vehicles has become higher and higher, and the problem of how to charge electric vehicles in a timely and effective manner has also followed. Charging piles, as a device designed to facilitate the timely charging of electric vehicles and other products, have received widespread attention and recognition once they came out. [0003] The market demand for electric vehicles such as pure electric vehicles...

Problems solved by technology

[0004] However, the scheme disclosed in the above-mentioned patent has the following disadvantages: since the terminal fixing member needs to penetrate and fix multiple terminals (including at least two charging terminals with larger diameters and several communication terminals), it is necessary to drill a plurality of terminals correspondingly on the terminal fixing member. holes, and the drilling accuracy is high, the volume of the terminal fixture must be large enough to distribute and fix the multiple terminals

However, the smaller the terminal fixture, the worse the heat dissipation effect, and the limited volume of the ceramic material terminal fixture will reduce the heat dissipation effect of the charging gun

Furthermore, when the charging gun is inserted into the car charging stand, the car's charging stand will impact the terminal fixing parts, and the traditional ceramic terminal fixing parts are easy to break
