Economical cable branch box

Abstract

The invention relates to an economical cable branch box, which comprises a metal outer box, a conductive grounding bar and at least one conductive wiring bar. A pair of insulating supports are arranged in parallel to the inner side of the metal outer box; the at least one conductive wiring bar is vertically arranged between the pair of insulating supports, and the two ends of the conductive wiring bar are fixedly connected with the corresponding insulating supports respectively; one side of the conductive wiring bar is provided with a plurality of wiring columns in linear arrangement, and one end of each wiring column is provided with a locking device; the conductive grounding bar is connected with the inner side of the metal outer box and is conductive; and the metal outer box is provided with a plurality of air holes and a plurality of inlet and outlet holes, wherein the inlet and outlet holes are in one-to-one correspondence with the wiring columns. Compared with the prior art, the economical cable branch box is simple to manufacture, low in cost, more flexible to use, convenient and quick, more reliable in connection and better in conduction effect and can prevent the problem of poor contact and the like; and the conductive wiring bar is arranged to the inner side of the metal outer box through the insulating supports, and besides, the conductive grounding bar can be grounded, so that a dual protection effect is achieved, the problems of electric leakage and the like can be prevented more effectively, and a safer use effect is achieved.

Description

technical field [0001] The invention relates to the field of cable equipment, in particular to a cable branch box. Background technique [0002] With the development and transformation of my country's urban and rural power grids, higher requirements are put forward for cable branch boxes, especially today when high-efficiency and high-quality work is emphasized. Time is becoming more and more precious for us, so cable branch boxes are convenient and fast. Installation and operation is the general trend. But it should also be objectively realized that the economical type puts forward higher requirements for the insulation structure and performance of the cable branch box, and the safety of the use of the cable branch box. If it is improper, the accident of the cable branch box will occur. [0003] Existing cable branch boxes generally use cable plugs to transfer or tap cables. One end of the cable plugs goes into the cable branch box and connects with the input cable or outpu...
