Description
Technical Field
The invention relates to the technical field of auxiliary tools for power construction, in particular to an indoor wire connector connection auxiliary tool.
Background
The electric wire joint is a key link necessary for connecting all sections of indoor lines into a whole, the electric wire joint needs to be tightly wound, sundries cannot be clamped in the middle of the joint, and an insulating layer in the area beyond the joint cannot be damaged. The number of the wire joints in the single switch and the socket panel in the common house is at least 2, the number of the wire joints is at least 3, and the number of the wire joints needs to be ensured by operators in a short time, so that the wire joints are convenient for users to use for a long time.
At present, two common modes of wire joints are adopted, one mode is that after a part of an electric wire insulating layer is removed, electric wires are aligned side by side and clamped by pliers, one or two electric wires are wound around the other or two electric wires by hand, and sealing treatment is carried out after the winding turns meet the standard requirements; the other is to remove a part of the insulating layer of the electric wire (or to carry the insulating layer), to arrange the electric wires side by side and to clamp them with pliers, to insert the electric wires into the corresponding round holes of the doubling device, to drive the doubling device to rotate by electric drive, to wind the electric wires, and to seal the wires. The winding modes commonly used for indoor wires are as follows: one winding, two winding and two winding.
The existing two wire joint modes need to remove a part of insulating layer, and after the wire is clamped by pliers, the winding joint can be realized. However, the length of the insulation layer removed is not uniform, so that workers can peel off a section randomly in order to meet the winding number standard, and after the winding number is met, the redundant part of the electric wire is cut off, so that the material waste is serious. Meanwhile, the existing pliers are easy to damage an insulating layer while clamping the wire, so that potential safety hazards are left for long-term use, manual winding is time-consuming and labor-consuming, labor intensity is high, and efficiency is low; the doubling device can improve winding efficiency, but winding quality can not meet acceptance requirements, secondary trimming or insulating layer cleaning is needed manually, and comprehensive benefits are not outstanding.
