A semi-rigid cable welding void rate control method and supporting tooling

Abstract

The invention discloses a semi-rigid cable welding void rate control method, comprising the following steps: S100, pre-treating the semi-rigid cable to be welded; S100, pre-treating the semi-rigid cable to be welded; S100, pre-treating the semi-rigid cable to be welded. S200, welding the semi-rigid cable and the central conductor; S300, welding the outer conductor of the semi-rigid cable and the connector by using the matching tooling; S400, take out the matching tooling and assemble the connector, the process can avoid high welding temperature, if the welding time is too long, At that same time, the process has very low requirements on solder and does not require precise soldering operation, which is conducive to ensuring the qualified rate of the product. In addition, the process can reduce the requirements on the product structure, avoid fixing the product modules, and is conducive to the research and development of new products.

Description

technical field [0001] The invention relates to the field of semi-rigid cables, in particular to a method for controlling the welding void rate of semi-rigid cables and matching tooling. Background technique [0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating layer that transmits power or information from one place to another. The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulated covering layer, the cable has the characteristics of internal electrification and external insulation. [0003] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand ...

AI Technical Summary

Problems solved by technology

[0007] (1) By increasing the heating temperature and heating time to meet the solder void rate requirements, it is easy to cause damage to the coating on the surface of the connector, serious oxidation of the solder joints, and it is easy to reheat other parts in the connector and melt the solder, which affects the performance of the connector ;

[0008] (2) Although the method of increasing the vent hole of the outer conductor of the connector can meet the requirement of solder void rate, it will increase the processing procedure, increase the production cost, and fix the design module, which is not conducive to the development of new products;

[0009] (3) The existing semi-rigid cable welding process has high requirements for welding, which not only increases the burden on the staff, but also increases the defective rate of the product
