Abstract
The invention provides a rapid plugging/pulling cable branching box. The branching box comprises a box body, three insulators, three copper bars, three connection wires, three T-shaped cable terminals, three straight line adapters and an insulation separation plate, wherein the insulators, the copper bars, the connection wires and the T-shaped cable terminals are arranged in the box body. Each of the straight line adapters comprises a conductive rod, an insulation layer, a rapid clamping head and a housing. One end of each of the straight line adapters is electricallyconnected with one T-shaped cable terminal in the box body correspondingly. The straight line adapters, the T-shaped cable terminals, the connection wires and the copper bars form a three-phase electric access. In use, the copper bars are correspondingly connected with three phase wires A, B and C of a ring main unit incoming cable. The straight line adapters are quickly clamped with rapid joints of three bypass cable joints via the rapid clamping heads. The branching box is simple in structure, low in cost and convenient to achieve. Laying distances of flexible bypass cables can be greatly reduced in use, so a difficulty in remote laying of power supply points and flexible bypass cables is solved and rush repair efficiency is increased.
Description
Technical field
