Charging gun, charging socket and charging device using charging gun

Abstract

The invention relates to the field of new energy charging connectors, and particularly provides a charging gun, a charging socket and a charging device using the charging gun. The charging device comprises a power supply device and a charging gun connected with the power supply device, and the charging gun comprises a gun body, wherein the gun body is provided with a plug-in mounting part which isplugged into a charging socket, and the peripheral surface of the plug-in mounting part is provided with a rolling fit structure in rolling fit with the adaptive surface of a plug-in mounting cavityin the charging socket so as to guide the plug-in mounting part to be plugged into the charging socket. A rolling structure is arranged on the plug-in mounting part and / or the charging socket of the charging gun. The friction force borne by the charging gun and the charging socket in the plugging and unplugging motion can be reduced, and the original sliding friction is converted into the rollingfriction of the rolling body and the contact surface, thereby reducing the plugging and unplugging force needed by an operator to insert the charging gun into the charging socket or unplug the charging gun from the charging socket, optimizing the operation experience, and improving the efficiency.

Description

technical field [0001] The invention relates to the field of new energy charging connectors, in particular to a charging gun, a charging socket and a charging device using the charging gun. Background technique [0002] With the development of technology, the popularization of new energy vehicles has solved the environmental problems caused by the depletion of traditional fossil fuels and the use of fossil fuels, because new energy vehicles use the batteries loaded in the car to supply power to them, and do not emit pollution to the external environment Harmful gases in the atmosphere, and safe and efficient charging of new energy vehicles has become an important factor affecting the popularity of new energy vehicles. [0003] In the prior art, the charging gun connected to the charging pile is generally inserted into the socket on the new energy vehicle, the charging gun is electrically connected to the socket, the socket is connected to the battery, and the electric energy...
