Description

Technical Field

[0001] The invention relates to the technical field of cable distribution boxes, and in particular to a self-supporting optical fiber communication cable distribution device. Background Art

[0002] Cable junction boxes are known in the industry as a type of industrial connector. They can convert an incoming power supply or data into multiple current or data signals through shunt conversion. Junction boxes are widely used in various occasions where cable branching is required, such as bridges, boxes, pipelines, cable trenches and other narrow spaces. They save space and are easy to install and maintain.

[0003] The existing cable junction box needs to connect multiple branch cables, but the position of the wiring post inside the junction box is fixed, and the position of the wiring post only corresponds to the position of the main cable. However, since the branch cables enter the junction box at different positions, the connection with the wiring post will cause the line length inside the branch cable to be inconsistent. The inconsistent branch line lengths will result in different pulling forces, resulting in a decrease in the service life of the cable. The cable is prone to breakage, which affects the transmission of the cable signal. Summary of the invention

Since the protruding column rotates inside the spiral groove, the upper rotating plate moves downward with the rotation, and the guide plate guides the upper rotating plate to move downward, thereby squeezing the cable to facilitate the user to connect the wires.
