Description

Technical Field

[0001] This utility model relates to the technical field of cable connectors with locking devices, specifically a cable connector with a locking device. Background Technology

[0002] A cable joint, also known as a cable head, is a node that connects various sections of cable into a continuous line. It is divided into intermediate joints and terminal joints. Cable joints are key components used to connect, fix or protect cables in cable lines. Their core functions include sealing, insulation and mechanical protection. Metal joints are mostly used in waterproof and bending-resistant scenarios, while plastic joints focus on lightweight design.

[0003] Patent CN212063452U discloses a cable connector, which includes a main body, an annular first end cap, and an annular second end cap. The first end cap is installed at a first end of the main body, and the second end cap is installed at a second end of the main body. The key feature is that a first inclined conical surface is provided on the inner wall of the main body near the first end, with the larger end of the first inclined conical surface facing the first end of the main body. The cable connector in this embodiment has a simple structure and a high degree of fit with high-voltage cables, making it easy to promote and use.

[0004] When laying cables, connectors are needed to connect them. Although the connector in the patent is relatively simple to operate, the end cap is prone to loosening under external force, causing abnormal cable joint connection and reducing the stability and sealing of the cable joint connection. To address this issue, we provide a cable connector with a locking device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cable connector with a locking device to solve the problems mentioned in the background art.
