Cable intermediate joint protection box

Abstract

The invention provides a cable intermediate joint protection box, comprising a protection box body with a hollow interior. The protection box body comprises an upper protection box body and a lower protection box body with the same structure. Docking plates with through holes are arranged on the outer edges of the upper protection box body and the lower protection box body. An upper fixing half body is arranged at each of the left end and the right end of the upper protection box body. A lower fixing half body is arranged at each of the left end and the right end of the lower protection box body. Bended arc-shaped slots are arranged on the upper fixing half body and the lower fixing half body. The bended arc-shaped slots are connected with the interior of the protection box body. A limiting device is arranged at each of the two ends in the protection box body. In practical application, cables close to joint ends are distributed in the bended arc-shaped slots. When the cables are pulled, the axial pull borne by cable joints can be effectively reduced through adoption of the bended arc-shaped slots.

Description

technical field [0001] The invention relates to a cable protection device, in particular to a cable intermediate joint protection box. Background technique [0002] With the continuous development of the domestic economy, the number of applications of power cables is increasing. At present, in the process of cable erection and application, the middle connector of the power cable is often the weak link of its power supply reliability. Due to the small size of the cable connector, and When the cable is erected, the cable spans a long distance and the weight of the cable is too large. During the long-term application process, the sealing of the cable contact and the reliability of the line connection will be reduced, so that the cable joint will have a lot of problems in the long-term use process. Great safety, especially the water ingress in the cable head and the decline of insulation performance, often lead to accidents such as cable short circuit and explosion. Therefore, ...
