Stress-prevention tool for insulation wire

Abstract

The invention relates to an electric tool, in particular to a stress-prevention tool for an insulation wire. The stress-prevention tool comprises a rotation wheel and a plurality of handles, wherein the rotation wheel is provided with an intermediate shaft, the handles are rotatably connected with the intermediate shaft, a groove opening is formed in the rotation wheel, each handle is provided with a rotation press wheel, the insulation wire is inserted between the rotation wheel and the rotation press wheel in a penetrating way by the groove opening of the rotation wheel, and the insulation wire is clamped by the rotation wheel and the rotation press wheel by rotating the handles and is bent and deformed along the rotation wheel. By the tool, the mechanical property of accurate positioning during bending the insulation wire is fully utilized, the production cost is reduced, the construction time is reduced, meanwhile, the stress of the wire and a wiring terminal is eliminated, a wirepositioning process during connection of the insulation wire and equipment is standardized, so that the physical phenomena of an electrothermal effect, wiring terminal breakage and the like caused byunfavorable contact surface are effectively solved, and oxidization and burning brought by a thermal effect are prevented.

Description

technical field [0001] The invention relates to an electric power tool, in particular to an insulated wire stress-proof tool. Background technique [0002] The construction quality of 10kV insulated conductors caused a large number of broken terminals, which directly affected the safe operation of the power grid. At present, construction personnel are not equipped with special tools when connecting and positioning 10kV insulated wires and equipment, and often use the body or other tools to assist in rough positioning. It is barely possible to solve the problem for small-diameter wires, and it does not harm the wires when the wire diameter is large. It is difficult to meet the positioning requirements, the wiring between the wires is not beautiful, and the positioning is too large or too small to cause incoordination between the wires. Especially in cold weather, due to the additional stress, the contact surface of the terminal is poor, and the temperature and contraction of...
