Description

Plug wire box Technical Field The application relates to the field of communication, in particular to a plug wire box. Background The junction box of the watt-hour meter is a special junction box in the standard wiring of the electric energy metering device, and is used for wiring and safety protection. In the operation process of replacing the ammeter junction box, workers need to conduct insulation wrapping on the removed electric wires. The common practice is to wrap the wires by using an insulating tape, if the wrapping is improper, short-circuit fire collision is easy to generate, the safety hazard is caused, after the junction box is disassembled, a plurality of wires are arranged, the phase sequence and the socket of each wire are difficult to identify, one wire is needed to be detected, the wires can be accurately connected to the newly replaced junction box, and in the process, the wires can be connected to the wrong socket for many times, so that the safety hazard is caused. In the process of replacing an ammeter junction box, an auxiliary device is needed, so that the safety of the ammeter junction box replacement process is improved. Disclosure of Invention In order to improve safety in the process of replacing an ammeter junction box, the application provides a plug wire box which is of a cuboid structure, wherein a wire guide rail is arranged on a first surface of the plug wire box, the wire guide rail is a deep hole perpendicular to the first surface, an insulating claw screw is arranged on a second surface perpendicular to the first surface, one end of the insulating claw screw, provided with a thread, extends into the wire guide rail, a first connecting clamping groove and a second connecting clamping groove are respectively arranged on a third surface and a fourth surface perpendicular to the first surface, the third surface and the fourth surface are parallel to each other, and a plurality of plug wire boxes are movably connected with the second connecting clamping grooves through the first connecting clamping grooves. After the electric wire is replaced, the electric wire is temporarily inserted into the wire track arranged on the surface, then the insulating claw screw is rotated, after the insulating claw screw is rotated downwards, the length of one end of the insulating claw screw, which is provided with the screw thread, stretches into the wire track is prolonged until one end of the insulating claw screw, which is provided with the screw thread, contacts the electric wire inserted into the wire track, and at the moment, the electric wire is tightly abutted on the side wall of the wire track due to extrusion of the insulating claw screw and is fixed. The third surface and the fourth surface are respectively provided with a first connecting clamping groove and a second connecting clamping groove, and a plurality of plug wire boxes are movably connected with the second connecting clamping grooves through the first connecting clamping grooves.
