Description

Technical Field

[0001] The utility model relates to the technical field of new energy charging, and more specifically, to a new energy plug-in device. Background Art

[0002] In order to achieve sustainable development, the new energy industry came into being, among which new energy vehicles are one of the industries with huge market potential. Charging piles, as the basic supporting facilities of new energy vehicles, have been widely used and promoted, and the protection of the input end of charging piles has also attracted more and more attention. Usually, the charging and plug-in device of new energy vehicles mainly includes a charging socket arranged on the vehicle body and a charging gun matched therewith. The charging socket further includes a socket shell and a socket body. The socket body is provided with a socket part that is plugged with the gun head of the charging gun. When the gun head of the charging gun is matched and inserted into the socket part of the socket body, the output terminals in the charging gun are aligned with the access terminal holes in the socket body and contact and conduct electricity.

[0003] Among them, it was found through search that the patent application number CN202022183443.2 discloses a new energy charging protection plug, including a new energy charging plug body, a fixed outer ring is sleeved on the right surface of the new energy charging plug body, and an anti-slip shell is inserted into the right inner side of the anti-slip shell, and a fixed rod is symmetrically fixedly installed at the upper and lower ends of the left side of the fixed outer ring, and a rotating screw is inserted into the interior of the fixed rod, and one end surface of the rotating screw inserted into the interior of the fixed rod is in contact with a fixed block;

[0004] When the structure is in use, the anti-skid shell facilitates the connection between the new energy charging plug body and the socket. At the same time, the anti-skid shell expands the spring inside the fixed outer ring to make the anti-skid shell contact with the surface of the socket, thereby preventing rainwater from penetrating into the inside of the socket during use. However, the structure is not easy to guide and limit the plug-in part when plugged together, and it is not easy for the output terminal to be in close contact with the input terminal, which is prone to disconnection.

Through the setting of the positioning cone column, the first nylon seat can be installed on the second nylon seat for positioning, so as to ensure the stability of the first nylon seat installed on the second nylon seat, and also facilitate the disassembly of the first nylon seat.

[0013] Technical effects and advantages of the utility model:
