Abstract

The invention discloses a low-fault cable branch box which comprises a box body 1, wherein an isolating plate 2 is arranged at the middle part of the box body 1; a load switch 3 is arranged at one side of the isolating plate 2; copper bars and cables 4 are arranged at the other side of the isolating plate 2; copper noses are arranged at the end parts of the cables 4; the copper noses are fixed on the copper bars through bolts; a protective cover 5 is arranged at the joint of the copper noses and the copper bars; and the protective cover is fixed on the box body 1 through bolts. The low-fault cable branch box is simple in structure and smart in design, the maintenance security is guaranteed, and wires are prevented from being falsely connected.

Description

technical field [0001] The invention relates to the box field, in particular to a low-fault cable branch box. Background technique [0002] Existing cable branch box is mainly made up of box body, cable, bus bar, load switch, arrester, sensor, cable connector, and wherein cable connector is made of an elbow plug and socket. The patent application document of Chinese application number 200520111202. X discloses a kind of low-fault cable branch box afterwards, and it comprises box body, cable, bus bar, load switch, lightning arrester sensor, cable connector, is characterized in that cable connector is copper One end of the copper nose is connected to the cable, and the other end is fixed to the branch end of the busbar by screws. Although the cable branch box with this structure has a low failure rate, it operates stably and has good safety performance. However, there are no safety measures at the copper bar and copper nose of the cable of this structure, which may easi...
