Method for pre-stripping wire outer skin

Abstract

The present invention relates to a method for stripping the sheath of an electric wire end. In this method of pre-stripping the wire sheath, the wire is heated near the end of the wire, so that the wire sheath at the heated place becomes molten, and then cooled. After the molten sheath at the heated place cools down, the bonding strength of the unmelted wire sheath connected to it will decrease. When in use, gently stroke the melting part with your hands to remove the outer skin. When using the wires pre-stripped by this method, the outer skin can be removed by gently rubbing the melting place with your hands, and there is no need to use wire strippers for stripping.

Description

technical field [0001] The present invention relates to a method for stripping the sheath of an electric wire end. Background technique [0002] Wires are widely used in daily life. Typically, the main body of the wire, the conductive core, is surrounded by an insulating sheath. The sheath is generally polyvinyl chloride material. When wiring, it is usually necessary to peel off the sheath at the end of the wire to expose the conductive core, and then connect the conductive core to other conductors. In order to peel off the outer sheath of the wire end, people often use wire strippers. However, the use of wire strippers often results in cutting or partial cutting of the conductive core (when the conductive core has multiple strands), especially when the wire is thin. [0003] Also someone burns the sheath at the end of the electric wire with fire to soften the sheath, and when it is not cooled, it is torn off quickly with hands or other tools, but the uncooled sheath sti...

Problems solved by technology

However, the use of wire strippers often results in cutting or partial cutting of the conductive core (when the conductive core has multiple strands), especially when the wire is thin

[0003] Some people use fire to burn the sheath at the end of the wire to soften the sheath, and quickly tear it off with hands or other tools when it is not cooled, but the uncooled sheath is easy to stick to the hands or tools

If the softened outer skin is cooled and then pulled hard, it is difficult to tear off and peel off the outer skin. This may be because the entire section of the outer skin to be peeled off is cooled due to thermal expansion and contraction. The inner conductive core is packed tighter, resulting in increased friction

Due to the difficulty of controlling the firing temperature in this method, the conductive core is likely to be oxidized
