AI Technical Summary

Technical Problem

The existing ring grid cabinet design has friction problems in the connection and protection of incoming cables, resulting in rapid damage to the cable or leakage.

Method used

A protective structure for inlet cables of the ring net cabinet is designed. By opening a through-hole and a placement groove on the side of the ring net cabinet main body, an annular plate, a through-through protection pipe and an extruded roller guide mechanism are built-in. The clamping and fixing of the cables are achieved by using linkage limiting components to avoid contact between the cables and the protective pipes.

Benefits of technology

It effectively reduces the friction between the incoming cable and the protective tube, prevents cable damage and leakage, improves the service life of the cable and the safety of the ring grid cabinet.

Abstract

The utility model belongs to the technical field of incoming cable protection, and particularly relates to a ring main unit incoming cable protection structure, which comprises a ring main unit main body, an incoming through hole and a placement groove, the incoming through hole and the placement groove are both arranged on the side edge of the ring main unit main body, an annular plate is placed on the inner wall of the placement groove, and the ring main unit main body is provided with an annular groove. The inner wall of the annular plate is fixedly connected with a penetrating protection pipe, and the inner wall of the penetrating protection pipe is connected with an extrusion guide rolling mechanism. The extrusion guide rolling mechanism comprises a fixing plate fixedly connected to the inner wall of the penetrating protection pipe, a strip-shaped through groove is formed in the surface of the fixing plate, and a first fixing rod is fixedly connected between the two end walls of the strip-shaped through groove. According to the utility model, the through protection pipe is arranged, so that the incoming cable does not contact with the inner wall or the end wall of the through protection pipe after penetrating through the through protection pipe, and therefore, friction can be greatly reduced, incoming cable damage caused by friction can be avoided, and a better protection effect can be achieved.
