Description

Technical Field

[0001] This utility model relates to the field of electric vehicle electrical connection technology, and in particular to a car charging socket that can be quickly modified. Background Technology

[0002] Aluminum busbar charging sockets replace traditional power cords with aluminum busbars to improve worker efficiency. The structure of these car charging sockets mainly includes straight-out and bent-out types. Straight-out charging sockets have the wires led directly out of the socket. Straight-out sockets are usually suitable for places with more spacious areas or where there are no special requirements for the direction of the wires. Additional fixing measures are needed to ensure the stability and safety of the wires, such as secondary locking mechanisms and other fixing structures.

[0003] The power cord of a bent-out charging socket is bent at a 90-degree angle inside the socket housing before being led out. Bent-out sockets are better suited for wiring problems in confined spaces, especially in limited spaces such as inside a car. Bent-out sockets are also more suitable for situations where the power cord needs to be led out in a specific direction, or where it is necessary to avoid poor contact or damage caused by the power cord hanging directly. Due to its internal structural design, bent-out sockets can better protect the power cord, reduce the risk of it falling off due to its own weight, and also reduce the probability of electric shock accidents.

[0004] Traditional car charging sockets have a relatively fixed cable outlet configuration due to design limitations of the cable outlet cover and protective cover components. There is only one cable outlet method. If socket products are needed for different scenarios or user needs, the entire socket can only be manufactured separately, which results in high R&D costs and low installation flexibility. Utility Model Content

[0005] The purpose of this utility model is to address the issue that the cable outlet form of existing car charging sockets is relatively fixed.
