Description

Technical Field

[0001] The utility model belongs to the field of electric connectors, and in particular relates to an adapter for a charging gun of an electric vehicle. Background Art

[0002] With the increasing popularity of new energy vehicles, different manufacturers use different charging gun interface models. In order to adapt to different charging gun interface models, an adapter structure connected to the charging gun interface has emerged. At present, the common adapters on the market are mainly composed of a connection end A connected to the charging gun interface and a connection end B connected to the charging car potential, a wire connected between the connection end A and the connection end B, and a shell that is respectively connected to the connection end A and the connection end B and receives the connected wires. Among them, in order to be able to receive the wires and match the connection with the connection end A and the connection end B of the shell, the volume of the shell needs to be made very large and the overall length will be relatively long. Since the overall structure of the adapter is relatively long after being connected to the charging gun, it is easy to collide with the cable connected to the charging gun during charging, and the cable has a certain weight during use. Once it is touched, it will swing, and it is also easy to cause the adapter to loosen and poorly connect with the charging gun, which may cause safety hazards such as leakage, fire alarm, and short circuit. Utility Model Content

After improvement, a hard bracket structure is used to connect the input and output ends at both ends together, which is not only convenient for installation, but also saves processes, and the length and volume are small, and the connection position is stable and safe. In addition, the bracket structure used can be laser welded to save connection space, reduce the heat generated when the resistor is energized, and further improve safety.
