Description

Technical Field

[0001] This utility model relates to the field of cable technology, and more specifically, to cable connectors. Background Technology

[0002] A cable joint, also known as a cable head, is a connection point used after a cable has been laid to connect the various sections of the cable into a continuous line.

[0003] A search revealed that application number CN202420004320.3 describes a cable and cable connector connection structure, relating to the field of cable technology. This utility model describes a cable connector structure where, when the connector and the fixing head are tightened, the abutment sleeve is inserted into the insertion channel. The abutment sleeve abuts against the clamping strip and pushes the clamping strip to clamp the cable, thereby strengthening the connection between the cable and the cable connector, ensuring connection stability, and guaranteeing electrical safety.

[0004] When using the above-mentioned utility model, the cable needs to be passed through the cable connector, then the waterproof cap needs to be fixed to the fixing head through the threaded structure, and finally the fixing head needs to be installed on the interface of the external equipment through the threaded structure. This means that the cable connector and the cable need to be rotated twice before and after installation, which is quite cumbersome.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
