Technical Field
[0001] The utility model relates to the technical field of electric vehicle charging equipment, in particular to an electric vehicle power supply connection structure. Background Art
[0002] The electric vehicle power connection structure is a structure used to charge the electric vehicle. The charger is connected to the socket installed on the electric vehicle through the charger plug, so that the charger can charge the electric vehicle. First of all, the traditional electric vehicle power connection structure is too simple. The sockets of most electric vehicle power connection structures are directly fixed on the electric vehicle, which is inconvenient to disassemble and maintain, and it is particularly troublesome to replace and repair. Secondly, when the socket of the electric vehicle power connection structure is connected to the charger plug, it is easy to loosen, resulting in the electric vehicle being unable to charge. In addition, when it rains, water easily enters the power connection structure, causing a short circuit. To this end, we propose an electric vehicle power connection structure. Utility Model Content
