Rope flexible connection welding method

Abstract

The invention relates to a rope flexible connection welding method which comprises the following steps of blanking, copper bush cold pressing, milling, welding and follow-up welding. When the rope flexible connection welding method is adopted, the volume of a circle is greater than that of an ellipse when the perimeter is the same, so that copper ropes in a flattened copper bush can extrude with each other and are firmly fixed; displacement is difficult to generate in an operating process; the connection stability is improved by adding the copper bush; the unwelded multi-strand copper ropes are firmly fixed by using the copper bush, so that the consistency of the final lengths of the copper ropes of a rope flexible connection product can be controlled accurately; the regularity of the copper ropes in a flexible connection manufacturing process is ensured effectively; the follow-up welding and mounting are facilitated; and multi-rope layered step welding can be achieved conveniently during the follow-up welding.

Description

technical field [0001] The invention relates to the field of electrical connection, in particular to a rope type soft connection welding method. Background technique [0002] In a broad sense, electrical connection refers to the collection of all electrical circuits in an electrical product, including power connection parts such as power plugs, power terminals, etc., power cords, internal wires, internal connection parts, etc.; All ways of connecting different conductors together. Electrical connections include: terminal blocks, PCB connectors, industrial connectors, junction boxes, heavy-duty connectors, cables, cable connectors, safety barriers, contacts, etc. In order to unify the terms, the general electrical connection refers to the electrical connection in the narrow sense, while the electrical connection component is used to refer to the electrical connection in the broad sense. Electrical connections are widely used in electronics, electrical, industrial production...

AI Technical Summary

Problems solved by technology

Copper stranded wires and copper braided wires are used as conductors, copper tubes or special-shaped conductors customized by customers are used as terminals at both ends, and the soft connection made by special treatment has the characteristics of high conductivity and strong fatigue resistance. , but because the rope-type soft connection is made of multi-strand braided in a single layer or multiple layers, it is often difficult to control the length of the copper rope, and it is also difficult to ensure the neatness of the copper rope at the fracture. In addition, due to the braided copper rope The copper wire diameter is thinner, not resistant to high temperature, and there are many problems in welding

At present, there is no rope type soft connection welding method that can accurately control the length of the copper rope of the soft connection, and is consistent with the copper rope at the connection end.
