Low-melting-point metal cable continuation device

Abstract

The invention relates to a low-melting-point metal cable continuation device. The low-melting-point metal cable continuation device is characterized by being composed of a low-melting-point metal inner ring, an insulating sleeve, a shielding copper mesh with low-melting-point metal coatings, and a heat gun. Grooves are formed in the two sides of the low-melting-point metal inner ring, and a cable core is connected to the grooves and welded. The insulating sleeve wraps the low-melting-point metal inner ring from the outer side for forming a welding spot outer insulating layer. The shielding copper mesh with the low-melting-point metal coatings is used for achieving welding of a cable metal shielding layer, and the two ends of the shielding copper mesh are coated with the low-melting-point metal coatings. In the use process, the heat gun is used for heating low-melting-point metal, so that the low-melting-point metal is melted for achieving the welding process. The low-melting-point metal cable continuation device is simple in structure, convenient to operate, safe and reliable, saves energy and protects environment, thereby being capable of being widely used in field of the cable continuation projects of rail transit, information communication and the like.

Description

technical field [0001] The invention relates to a cable connecting device, which uses low melting point metal as welding material. The whole welding process can be carried out at a relatively low temperature, which is more energy-saving and avoids damage to the core wire and insulation layer caused by high temperature. At the same time, the strength and conductivity of the welding head made by the low-temperature welding process are far superior to the traditional metal clamping method. The low-melting-point metal cable connection device provided by the invention has the advantages of simple structure, convenient operation, energy saving, environmental protection, safety and reliability, and can be widely used in the field of cable connection engineering such as rail transit and information communication. Background technique [0002] Cable splicing is an important part of communication line construction. Cable failures are often caused by external force damage, damp insula...

AI Technical Summary

Problems solved by technology

Compared with the mechanical clamping method, high-temperature welding has higher reliability, but the operating temperature of high-temperature welding exceeds 100 degrees Celsius, which not only consumes a lot of energy, but also often leads to damage to the core wire and insulation layer, which affects the welding quality and causes secondary failures
