Abstract

The invention belongs to the field of new energy, and particularly relates to a charging gun for a new-energy electric vehicle. The charging gun for the new-energy electric vehicle comprises a gun body, wherein a charging head is fixedly connected to the front end of the gun body, and a cavity is formed in the gun body; an insulating cylinder is fixedly connected into the cavity, and a liquid storage cavity is formed between the insulating cylinder and the cavity; the liquid storage cavity is filled with an insulating liquid, and two conductive strips are correspondingly arranged on the two sides of the insulating cylinder in a penetrating mode; the two conductive strips are correspondingly and electrically connected with a power supply line and the charging head, and the insulating cylinder is internally provided with a conductive plate, two arc-shaped grooves and two conductive blocks; the conductive plate is rotatably connected with the cavity and can rotate along the axis of the insulating cylinder; the two arc-shaped grooves are symmetrically formed in the two sides of the inner side wall of the insulating cylinder; and the two conductive blocks are arc-shaped blocks, the twoarc-shaped blocks are correspondingly and fixedly connected to the two ends of the conductive plate and coincide with the circle center of the insulating cylinder, and the arc-shaped blocks are slidably connected with the inner side wall of the insulating cylinder. According to the charging gun for the new-energy electric vehicle, automatic power off can be realized when the temperature is too high, so that security in the charging process is improved, and a fast heat dissipation effect can be realized.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a charging gun for a new energy electric vehicle. Background technique [0002] New energy electric vehicles refer to vehicles powered by vehicle-mounted power supplies, driven by motors to drive wheels, and vehicles that meet the requirements of road traffic and safety regulations. They have high energy efficiency and are clean energy sources that cause less pollution to the environment. [0003] During the use of new energy electric vehicles, it is necessary to charge the on-board power supply by connecting the charging pile with the help of a charging gun. The charging gun is completely inserted into the charging port of the car during use. The existing charging gun has long charging time and high current. Therefore, in some high-temperature weather, it is easy to cause the heat at the connector of the charging gun to be too high, and the heat cannot be dissipated in time...
