Technology for welding copper plate joint and multi-strand or weave copper wire, and clamper thereof as well as electrode as clamper

Abstract

The invention discloses a welding procedure for welding conductive copperplate connectors and a plurality of copper wires or weaved copper wires, a special fixture thereof and a resistance welding electrode which is also used as a holding fixture. The welding procedure comprises the steps as follows: the stop ends of the copper wires or the weaved copper wires are formed into strip-shaped connectors which are processed by the holding fixture through prepressing to lead one surfaces of the strip-shaped connectors to form a plurality of heaves, and then the bulging surfaces of the strip-shaped connectors are welded with the copperplate connectors; or a connecting copperplate can be preprocessed to machining one end of the copperplate with connectors into a structure with a rectangular groove, and the rectangular groove at one ends of the copperplate connectors is welded with the strip-shaped connectors of the copper wires or the weaved copper wires. A fluted structure corresponding to the heaves of the strip-shaped connectors is arranged on one plane surface of the adopted special fixture; the fluted structure corresponding to the heaves of the strip-shaped connectors is arranged onone plane surface of the adopted resistance welding electrode which is also used as the holding fixture. By adopting the welding procedure, the special fixture thereof and the resistance welding electrode, the firm connectors can be obtained through welding, and the energy consumption is low, the melting area of the connectors is sufficient and the conductive area requirement can be satisfied.

Description

technical field [0001] The invention relates to a welding process, in particular to a welding process for connecting copper plate joints with multi-strand copper wires or braided copper wires. The invention also relates to a jig used in this welding process and a resistance welding electrode double as a jig. Background technique [0002] In electronic equipment, welding of multi-strand copper wires or braided copper wires and conductive copper plates is often involved. For this technical problem, brazing method or direct resistance welding is usually adopted. Due to the brazing, certain solder and flux are required, which has the disadvantage of high cost. For direct resistance welding, the process usually includes two steps of sealing and welding. The sealing is to combine the parts of the multi-strand copper wire or the braided copper wire as the joint through energization, and then connect the joint part with the conductive wire. The joints of the copper plates are ove...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the welding of conductive copper plate joints and multi-strand copper wires or braided copper wires is resistance welding between two planes, which requires more energy to be completely fused; Welding, due to its large thickness, consumes a lot of energy

It is easy to have the defects that the welding fusion area is not enough and the conductive cross-sectional area cannot meet the requirements

[0004] Therefore, it is necessary to design a welding process suitable for conductive copper plate joints and multi-strand copper wires or braided copper wires to overcome the defects of insufficient welding area and high energy consumption in the prior art
