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: see Fig. 5.

[0021] For the first defect, the groove width of 0.5mm where the resistance wire is installed at the blade 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, and change the original Φ0.24mm resistance wire to Fold in double strands into a U shape, and keep a necessary gap in the middle of the U shape to ensure that they 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.

[0022] 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 siz...

Abstract

As monopolized by American product, the series defects in prior art of the wire hot-stripping clamp include 1) unreasonable hot wire arrangement and only 1 / 3 useful work; and 2) disobeying design requirement to remove the cold-hot joint out of body. In the disclosed product, using U-shaped resistance wire on blade instead of the original I-shaped one to prolong the wire one time and increase useful work one time too; applying paralleled double-ply wires on supporting part to increase the section area one time and reduce all of the surface load, useful resistance and reactive consumption one half; and moving the joint into body. This invention overcomes problem in current product and improves performance greatly.

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...
