A low-voltage cable branch box outlet module

Abstract

An outgoing line module of a low-voltage cable branch box adopts a modular structure, is a load switch provided with fuses, and is formed by combining a base provided with plug type power-on interfaces and an upper cover provided with fuses and arc extinguish chambers in a hinged manner; each plug type power-on interface is located below the base and matched with a copper busbar of a bus system in the low-voltage cable branch box; each fuse is mounted on the inner surface of each upper cover; the position of a touch knife of each fuse and the base form one arc extinguish chamber; a metal arc extinguish piece is mounted in the arc extinguish chamber where the base corresponds to the touch knife of each fuse; and outgoing cables are mounted in cable clamps comprising fixing cable clamps and movable cable clamps respectively.

Description

technical field [0001] The invention relates to an electrical connection part, in particular to an outlet part for connection of incoming and outgoing lines in a low-voltage cable branch box, mainly used for cable connection of incoming and outgoing lines outdoors, in cable wells and in corridors. Background technique [0002] Cable branch box With the development of distribution network cabling process, when the distribution of independent loads with small capacity is relatively concentrated, cable branch boxes have been widely used to connect multiple branches of cables, because the branch box cannot directly operate each channel. It is only used as a cable branch, and the main function of the cable branch box is to branch or transfer cables. The so-called cable branching refers to: there are many small-area cables on a relatively long-distance line, which often leads to waste of cable use. Therefore, when going out to the power load, the main large cable is often used to ...

AI Technical Summary

Problems solved by technology

[0011]However, a large number of distribution boxes currently in use are directly connected to copper bars without protection, which will lead to:

[0012] ①In case someone touches the exposed copper wire, it will directly lead to the danger of electric shock;

[0013] ② If any branch circuit breaks down, the whole branch box is in crisis;

[0015] ④If a fault occurs, it is very troublesome to find it, and it must be searched one by one

However, this patent still adopts ordinary copper bars for incoming and outgoing lines, which does not solve the problem of exposed copper bars, and is prone to the risk of electric shock when outgoing lines
