Device and method for coupling brazing of cable connector and cable line and pin tube cavity contact

Abstract

The invention relates to a brazing device and method for a cable wire and a pin lumen contact couple and a cable joint, belonging to the technical field of cable connection in the electric power industry. It is characterized by a pair of graphite or graphitized electrodes I for elastically clamping the base of the weldment, an electrical control system III for generating low voltage and high current, and a brazing operation table IX. The voltage 2-15V and the current 50-500A are transmitted to the base of the weldment, so that the solder in the pin cavity or wiring hole of the base of the weldment is heated to the melting temperature of 130-600°C, and then the contact between the cable and the pin cavity is completed. Couple or cable gland solder connection. The effect and benefit of the present invention is to realize the good connection between the cable wire and the pin lumen contact couple, the cable joint, etc., the brazing equipment has high processing efficiency, good safety protection, high degree of automation, and is easy to operate and pleasant.

Description

technical field [0001] The invention belongs to the technical field of cable connection in the electric power industry, and relates to a brazing device and method for a cable wire and a pin lumen contact couple and a cable joint. Background technique [0002] Compared with traditional fusion welding, the biggest feature of brazing is that the base metal does not melt, the working temperature is low, the welding deformation is small, and the dimensional accuracy of the weldment is high. Therefore, the brazing technology is especially suitable for forming base metal or base metal that is difficult to melt Welding, such as electronics industry, instrumentation industry, aerospace technology, machinery manufacturing technology, etc. [0003] However, there are serious defects and deficiencies in the traditional brazing connection technology and devices, which lead to large differences in the processing quality (brazing depth, verticality, etc.) The welding efficiency of the equ...

AI Technical Summary

Problems solved by technology

During the brazing process, the temperature of the high-temperature solder should reach about 300-450°C. If it is too high, it will cause oxidation of the substrate surface and the solder, resulting in poor quality of the substrate. Therefore, there is a requirement for the upper limit of the brazing temperature; during the brazing process , the temperature of the high-temperature solder should not be too low, otherwise the solder cannot be completely melted, so that the cable, solder and pin lumen contacts cannot completely wet the weldment, resulting in clamping, weak welding, and high resistivity

The brazing time of the contacts should not be too long. If the time is too long, the oxidation of the weldment will exceed the standard.
