Description

Technical Field

[0001] The utility model belongs to the technical field of wire strippers, and in particular relates to an electrothermal charging wire stripper. Background Art

[0002] Electrical engineering and related fields often require stripping wire insulation to connect, repair or replace wires and cables. In some areas, especially in cold northern regions, low temperatures in winter can make insulation brittle and difficult to strip. This can cause unnecessary damage to the wire during the wire stripping process, affecting the performance and safety of the circuit.

[0003] Generally speaking, the insulation layer is made of different materials, and its pore size and properties are also different. In order to effectively strip the insulation layer, different specifications and types of wire stripping tools are usually required. The wire stripping tools on the market are mainly manual. The operator needs to manually grasp the tool, position the blade or clamp on the insulation layer, and then forcefully strip the insulation layer. However, these tools are usually unable to adapt to the adverse effects of cold weather on insulation materials, which increases the difficulty of operation and may cause damage to the wire, reducing the quality and reliability of the wire.
