Problems solved by technology

[0002] In the existing electronics industry, when welding high-frequency electronic components, network components, hardware components, inductors, IC cards, mobile phone speakers, sounders, and micro motors, it is often necessary to weld enameled wires and thin metal wires, especially those involving When welding the copper-clad aluminum enameled wire, it is necessary to manually wind the wire for soldering. Since the copper-clad aluminum enameled wire is relatively brittle, it is easy to break the copper-clad aluminum enameled wire. , that is, the electrodes will stick together with the enameled wire, and it is easy to tear off the solder joints, resulting in desoldering. The operation is too complicated and the efficiency is low, and auxiliary solder tin is needed
Due to the influence of the above factors, the electrodes of existing spot welding machines cannot complete the spot welding of copper-clad aluminum enameled wires, and the welding quality is difficult to control

Abstract

The invention relates to a four-leg spot welding contact. An electrode of a conventional spot welding machine is incapable of completing the spot fusion welding of copper-clad aluminium enameled wires, and the welding quality is difficult to control. The four-leg spot welding contact comprises four cylindrical electrode blocks, wherein the tail ends of the four cylindrical electrode blocks are integrally connected so as to form a welding head, the rest of parts of the four cylindrical electrode blocks are insulated, the end surface of the welding head is provided with an edge and arc transitional bands, the arc transitional bands are sleeved with a heat collecting sleeve which is a plane arc copper foil sleeve, the lower end of an insulation crack ends at a through hole, the distance between the through hole and the lower end surface of the welding head is in the range of 5-10mm, and the through hole is an equilaterally quadrilateral through hole. The four-leg spot welding contact has the advantages that the four-leg spot welding contact is simple in structure and convenient to machine, the adhesion phenomenon of the electrode is avoided, and the enameled wires can be protected from being broken by pressing during welding. The four-leg spot welding contact is suitable for various spot welding machines and is particularly suitable for the welding of the copper-clad aluminium enameled wires.
