Description

Technical Field

[0001] The utility model relates to the technical field of cable joints, in particular to a locking wired cable joint. Background Art

[0002] With the continuous development of the electromechanical industry, various types of cables and wires used to transmit power have also been widely used. Cable is a device for transmitting electric energy or signals. Due to manufacturing, transportation and installation, there are certain restrictions on the length of each cable. During the laying process, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. Cable locking joints are usually required between cable joints and cables to lock and fix the cables and cable joints.

[0003] For example, a locking cable connector that is easy to install and has a publication number of CN217282154U is provided. The connector body is first placed at the position where the device needs to be installed, and then the connecting ring is put on the connector body. After the first mounting hole and the second mounting hole are aligned with the corresponding mounting holes on the device, the connector is fastened with the second screw. The cable is passed through the inner cavity of the connector body and adjusted to a suitable length. The first locking member and the second locking member are clamped to the connector body from both sides and then fastened with the first screw to complete the installation. The entire installation process uses electric or pneumatic installation tools to facilitate the improvement of installation efficiency. However, the device still has certain defects. The cable connector is fastened with the first screw, which is not convenient for disassembly and installation, which increases the difficulty of processing and disassembly of the parts of the cable connector, is time-consuming and labor-intensive, and is not convenient for daily laying of cables and regular inspection and maintenance.
