Description

Technical Field

[0001] This application relates to the field of insulation layer removal processing, and particularly to a thermal wire stripper pliers. Background Art

[0002] As the name implies, a high-temperature wire is a heat-resistant wire made of special materials, processed by using high-temperature and high-strength materials through a special process. Its main features are high temperature resistance, insulation, fire and flame retardance, corrosion resistance, aging resistance, weather resistance, high strength, high modulus, anti-static electricity, smooth appearance, etc. Before using a high-temperature wire, it is necessary to remove the insulation layer at the end of the wire body before wiring.

[0003] When removing the insulation layer in the prior art, a small knife or a general wire stripper pliers is generally used. A common wire stripper pliers has a blade at the jaw. The high-temperature wire is placed at the jaw position, and the insulation layer is cut open by the blade, and then force is applied to peel off the temperature-sensitive wire, exposing the metal wire.

[0004] When cutting the wire with the blade, it is necessary to rotate to increase the opening, which may not completely remove the insulation layer. Using brute force may even cause the high-temperature wire to be pulled. It is easy to generate an angle between the traction direction at the wire stripping end and the horizontal axis of the high-temperature wire, which is prone to pulling deviation, resulting in the wire inside the wire stripping part of the high-temperature wire being broken.

[0033] A high-temperature wire is a heat-resistant wire made of special materials. Its main characteristics include high temperature resistance, insulation, fire and flame retardance, corrosion resistance, aging resistance, weather resistance, high strength, high modulus, anti-static electricity, and a smooth appearance. Before using the high-temperature wire, it is necessary to remove the insulation layer at the end of the wire body before wiring. When stripping the insulation layer in the prior art, a small knife or an ordinary wire stripper is generally used. A common wire stripper has a blade at the jaw. The high-temperature wire is placed at the jaw position, and the insulation layer is cut open by the blade, and then force is applied to strip the temperature-sensitive wire, exposing the metal wire. When cutting the wire with the blade, it is necessary to rotate to increase the opening, which may not strip the insulation layer cleanly. Using brute force may even cause the high-temperature wire to be pulled. It is easy to generate an angle between the traction direction at the stripping end and the horizontal axis of the high-temperature wire, which is likely to cause the wire inside the stripping part of the high-temperature wire to break.

[0050] Please refer to Figure 1 and Figure 8, the adjusting member 21 is used to adjust the two wire stripping pliers bodies 22 to approach or move away from each other.

[0053] The technical principle of the embodiment of this application is as follows: When processing the high-temperature wire, the high-temperature wire is perpendicular to the wire stripping cutter head 24, and then the wire stripping pliers body 22 is adjusted to be opened, and the high-temperature wire is placed into the embedding groove 241 on the side with the positioning ruler 25, and the front end of the high-temperature wire abuts against the stop line segment 252 of the positioning ruler 25. When heat stripping the high-temperature wire with the heat stripping pliers, the high-temperature wire can be kept in the embedding groove 241, so that the wire is restricted from moving back and forth or up and down. Then, the two heat wire stripping pliers bodies 22 are quickly buckled by the first positioning part 243 and the second positioning part 244, so that the wire stripping cutter heads 24 are closed, further restricting the high-temperature wire from moving left and right; then the power is turned on, and the heating core 231 drives the wire stripping cutter head 24 to heat, and the insulating layer on the high-temperature wire is subjected to hot melting treatment. After hot melting for 5-10 seconds, the two wire stripping pliers bodies 22 are controlled to move away from each other. At this time, the wire stripping pliers body 22 drives the two ends of the high-temperature wire to move in the direction away from each other, separating the hot-melted insulating layer from the high-temperature wire core, and thus completing the hot wire stripping processing of the wire without damaging the wire body. The whole wire stripping efficiency can be increased by about more than 1 time. The efficiency is significantly improved, and the complete high-temperature wire can be better stripped, protecting the high-temperature wire to the greatest extent; the temperature can be controlled and adjusted, the insulating layer can be quickly melted, pulled off, not charred, not adhered, and various low-temperature and high-temperature insulating materials can be stripped, such as PVC, nylon, and Tefion, etc. And it can be quickly heated, the temperature is adjustable, and it meets ROHS. It is internally equipped with a precision heating wire with ceramic encapsulation, which can greatly improve the thermal efficiency, reduce the power consumption, and prevent oxidation; the cutter head has the characteristics of high temperature resistance and wear resistance; the handle is small and light, about 122 grams, and is flexible and convenient to use, facilitating work in narrow places and effectively improving work efficiency.
