DC charging gun insulation shell

Abstract

The invention discloses a DC charging gun insulation shell. The DC charging gun insulation shell comprises a gun body and a shell, wherein the shell is arranged at a top end of the gun body, the interior of the shell is of a hollow structure, the shell is connected with an outer surface of a top end of the gun body by integrated casting mould, a handle is arranged at a right side of the gun body in an inclination way, the handle is connected with a right side of the gun body by integrated casting mould, a top end of the handle is similarly connected with a bottom end of the shell, a wire is connected with a bottom end of the gun body and is electrically connected with the gun body, an insulation sleeve is arranged at a position, arranged at an outer surface of the gun body, of an intersection point of the gun body and the wire, the insulation sleeve sleeves a position, near to an edge of the bottom end, of the outer surface of the gun body, a slot is connected to a port of a left end of the gun body by integrated casting mould, insertion cores are uniformly arranged in the slot, an air relief piece can be used for balancing air pressure generated when a buckle cover and the slot are in contact during plugging action, and a plugging blocking phenomenon caused by air pressure during plugging is prevented.

Description

technical field [0001] The invention belongs to the related technical field of charging guns, and in particular relates to an insulating shell of a DC charging gun. Background technique [0002] The electric vehicle charging gun is used as the interface between the charging equipment and the electric vehicle rechargeable battery, and can perform related charging operations for the battery inside the electric vehicle. [0003] The existing charging gun insulating shell technology has the following problems: the charging gun needs to be fixed by the corresponding insulating shell during use, and when not in use, the corresponding buckle cover should be used to seal the slot, so as to avoid the inside of the charging gun. In actual use, we found that when the button cover is fastened on the surface of the slot, when performing corresponding actions such as plugging and unplugging, it will be difficult to plug in and out due to the pressure generated by the seal. The user needs...

Problems solved by technology

[0004] The purpose of the present invention is to provide a DC charging gun insulating case to solve the problem that the charging gun proposed in the background art needs to be fixed through the corresponding insulating case during use, and when not in use, the corresponding buckle cover should be used to fix the charging gun. The slot is sealed to prevent the metal components in the charging gun from contacting the user. In actual use, we found that when the cover is fastened on the surface of the slot, it will be affected by the seal during corresponding actions such as plugging and unplugging. Due to the pressure, it will be difficult to insert and unplug, and the user needs to spend a lot of force to insert or break free to fix the slot, which is not only time-consuming and labor-intensive, but also has a low degree of humanization.
