Abstract

The invention discloses a new structural DC charging gun, comprising a wiring tube and a screw nut, wherein the upper left side of the wiring tube is provided with the screw nut; the wiring tube is sleeved with the screw nut; the upper left side of the screw nut is provided with a wiring terminal; the upper left side of the wiring terminal is provided with a housing; and the upper left side of thehousing is provided with a plug connector. In the new structural DC charging gun of the present invention, a conventional engagement mode of the wiring terminal is changed to the current threaded rotation connection mode, so that the stability of the wiring terminal can be better improved. Thus, a wiring terminal falling phenomenon caused by complicated end line and disordered arrangement in thewiring terminal is avoided, thereby avoiding greater dangers. A high-temperature-resistant layer is applied to the outer side of the housing, so that the charging gun cannot burn due to excessively high temperature during charging, and the service life of the charging gun is prolonged.

Description

Technical field [0001] The invention belongs to the technical field related to electric vehicles, and specifically relates to a DC charging gun with a new structure. Background technique [0002] An electric vehicle refers to a vehicle that is powered by an on-board power supply and driven by a motor to drive wheels, and meets the requirements of road traffic and safety regulations. Because of its smaller environmental impact than traditional cars, its prospects are widely optimistic. As the charging connector between the electric vehicle and the charging pile, the convenience of the charging gun directly affects the user's overall evaluation of the use of the electric vehicle. [0003] The existing DC charging gun technology has the following problems: the terminals of the existing DC charging guns are usually connected directly by snap connection, so that the stability of the connection is unstable, and the phenomenon of falling off may occur, and in severe cases, it will happen...
