High-strength tensile tinned wire

Abstract

The invention discloses a high-strength tensile tinned wire, which relates to the technical field of tinned wires and comprises a structural strength layer, a high-temperature-resistant performance layer arranged on the inner side of the structural strength layer, a sealing protection layer arranged on the outer side of the high-temperature-resistant performance layer, an isolation protection layer arranged on the inner side of the sealing protection layer and arranged on the surface of the inner layer. The tinned wire connector has the advantages that extrusion locking is performed in the connector through internal pressure, hydraulic tools are not needed, manual operation can be realized, wire cores can be positioned in the center of the connector, wire core abrasion is reduced, connection strength can be improved during locking, multiple strands of tinned wire units can be isolated from one another, and the tinned wire connector is convenient to use and high in practicability. And the unique outer protective layer structure is designed, so that the corrosion resistance, the wear resistance, the structural strength, the high temperature resistance and the isolation performance of the cable body can be integrally improved, the protection capability on the internal cable core is better, and the service life of the cable body is prolonged.

Description

technical field [0001] The invention relates to the technical field of tinning wire, in particular to a high-strength tensile tinning wire. Background technique [0002] Tin-plated wire is different from existing copper wire. Tin-plated wire can prevent copper from being oxidized when it is directly exposed to the air. Therefore, tin-plated wire is widely used by people. [0003] When the tinned wire is applied to the European cable butt joint, it is often necessary to use a joint during the butt joint. After inserting the copper wire core of the tinned wire into the joint, it is often necessary to use hydraulic pliers and other auxiliary tools to compress the extruded joint, and then To achieve the effect of docking lock; [0004] However, this method is cumbersome to operate, and the single-person operation is more complicated, and the method of squeezing and locking from the outside cannot be applied to the use of tinned wires of different specifications, which has certa...

AI Technical Summary

Problems solved by technology

[0004] However, this method is cumbersome to operate, and the single-person operation is more complicated, and the method of squeezing and locking from the outside cannot be applied to the use of tinned wires of different specifications, which has certain limitations;

[0005] Moreover, the protective effect of the outer sheath of the existing tinned wire is relatively single, so due to the uncertainty of the use environment and usage scenarios, the tinned wire is prone to breakage, bending and corrosion, etc., thus reducing its service life, and When carrying out the butt joint of carbon fiber wire body to realize the electrical connection between the wire and the carbon fiber wire body, the connection method is usually relatively simple, and its overall connection performance and protection performance are not good, although there are also methods that use hot pressing and then continuous dipping way, but the process is complex and troublesome to operate
