Problems solved by technology

When the 4A working current is fed in, the resistance wire exposed outside the body shows a dazzling bright spot due to no load and high temperature. It is this failed design that severely restricts the power input of the American thermal stripping pliers, and greatly reduces the impact current resistance. Limited, the lifespan is very short, the warranty period of such a high-end product is only three months

Embodiment Construction

[0020] The method that the present invention implements is: to the first kind of defect, the groove width 0.5mm that the resistance wire is installed at the blade place has no possibility of expansion, but the original groove depth of 0.8mm still has room for expansion, so it is decided to deepen the groove depth to 1.2mm, The original Φ0.24mm resistance wire becomes double folded into a U shape, and a necessary gap is kept in the middle of the U shape to ensure that it will not touch each other and short circuit. The solder joint with the site (thermal stripper shell) is moved from the front to the rear, thus doubling the total length of the resistance wire on the blade. This means that the power distribution in the blade part has doubled to 2 / 3 of the total power.

[0021] For the second kind of defect, the present invention can meet the requirements of transformation due to the 0.6mm groove width and 1mm groove depth at the support, so the groove size is not changed, but th...

Abstract

Conductor thermal stripping pliers relate to electric heating tools and are special tools for stripping thermoplastic plastic sheaths. It is widely used in thermal stripping of wire insulation in aerospace, military and industrial industries. In the present invention, a heat pipe type heating structure is arranged in the stainless steel tweezers profile product, the front end is a blade for stripping wires, and a U-shaped resistance wire is arranged in the heat pipe at the blade, and the U-shaped structure is used to replace the original I-shaped structure at the blade. Resistance wire, thus doubling the effective power accordingly. In the supporting part, the original single-strand resistance wire is changed into double-strand parallel connection, the surface area of ​​the resistance wire in this part is doubled, the surface load is reduced by half, and the effective resistance and reactive power loss are reduced by half, and the hot and cold joints are moved into the The body meets the technical requirements of the heat pipe. As a result, the reactive power loss of the product is reduced, and the performance is obviously greatly improved.

Description

Technical field [0001] The invention relates to electric heating tools. It is a special tool for peeling off thermoplastic insulation. It is widely used in thermal stripping of outer insulation of aerospace and military wires. Background technique [0002] The wire insulation layer used in the aerospace and military industry has high temperature resistance and thin skin, and also has extremely high requirements for mechanical damage. Therefore, the wire stripping tools used in daily life cannot be applied in this field at all. At present, in China, the thermal stripping of aerospace and military wires is The tool is basically monopolized by the "wire heat stripper" in the United States. However, after contacting and in-depth research on this high-tech product sold at sky-high prices in China, it is found that the product is not perfect and has serious design flaws. [0003] "Wire thermal stripping pliers" is an electric heating product. Conventionally, the first task of d...
