Abstract

The invention relates to a charging gun with a dragging protection function. The charging gun comprises a gun body with an inner cavity, a plug, a locking part and a wiring harness; the plug is rotationally connected with the gun body; the plug is sleeved with a torsional spring; the two ends of the torsional spring are connected with the gun body and the plug respectively; a circumferential cam groove, which is closed and inclined along the rotary axis of the plug, is formed in the plug; a cam push rod matched with the circumferential cam groove is arranged on the gun body; the cam push rod is arranged in the circumferential cam groove; a terminal placed in the inner cavity is arranged on the gun body; a plurality of horizontally arranged ejector pins are arranged on the plug, multiple contact conductors are mounted on the terminal, and the contact conductors are in contact with the ejector pins in a one-to-one correspondence manner; an inserting-connecting sleeve is glidingly inserted and mounted on the gun body; the wiring harness is fixedly connected with the inserting-connecting sleeve; and one end of the wiring harness is placed in the inner cavity and connected with the terminal. By virtue of the charging gun, the normal charging use of a vehicle can be satisfied while it is ensured that the charging gun can be in a power-down state quickly in suffering from pulling force so as to be separated from the vehicle elastically and safely in an emergency condition.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a charging gun with a drag protection function. Background technique [0002] Due to the constraints of technological development and the influence of external factors such as weather and charging environment, the charging process of electric vehicles is usually relatively slow. According to the average charging time, even if it is to reach 50% of the rated power, it usually takes 20 hours at the fastest. - about 30 minutes; and such a long waiting period can easily make drivers sleepy, or forget about the charging event itself and focus on other things; On-duty self-service operation, so there will be no staff to remind the charging situation in time or perform the operation of plugging and unplugging the charging gun. [0003] Therefore, based on the above situation, once the charging is completed or the charging time is over, or the driver encounters an emergency,...
