Wire connecting method

Abstract

The invention provides a wire connecting method. The electric wire connecting method comprises the following steps of concentrically stranding a wire main body and shielding members arranged on the periphery of the wire main body in a cladding mode to form a wire; inserting the wire into a connector and using the wire after the pressure welding of the wire, wherein the outer diameter of the wire main body is formed to be larger than the outer diameters of the shielding members and a gap is formed between shielding members; and forming an insulator through annularly extruding and cladding the flame-retardant halogen-free material onto the wire main body and the shielding members. Each shielding member is composed of a cylinder and a metal pipe, wherein a braided shielding wire and an outersleeve are sequentially arranged at the periphery of an inner sleeve so as to from the cylinder, and the metal pipe is in butt joint with the cylinder. According to the wire connecting method of the invention, the time is saved and the quality is improved. Meanwhile, the welding is saved and the wire opening time is shortened. The consumption of intermediate protecting materials is also saved. Thequality is improved, and the fracture risk of connecting nails is shielded.

Description

technical field [0001] The invention relates to the field of automobile electric wires, in particular to a method for connecting electric wires. Background technique [0002] Since the interior of the car is a very complicated small environment, there are various complicated situations such as vibration, friction, ozone, oil pollution, high heat, cold and electromagnetic radiation, which require that the car wire must be different from the general wire and cable. And with the continuous update of automobile functions, the requirements for automobile wires are also increasing. Due to the continuous upgrading of vehicle grades, electrical and electronic devices are widely used in automobiles, and the amount of automobile wires is also increasing exponentially. Existing automobiles During the processing of wires, it is often necessary to connect two wires together, and because automotive wires must be flame-retardant, high-temperature resistant, anti-oxidation, waterproof, anti...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the connection between the two wires is covered with adhesive tape after welding. Since the diameter of the single side of the connecting nail of each wire is too small, and the welding point is relatively fragile, it is easy to disconnect or short circuit, and the adhesive tape is often not tightly wrapped. , poor waterproof performance, water leakage can easily cause signal interference and other problems, which will cause open circuit or short circuit of the wiring harness circuit, thus causing quality and safety risks
