Abstract

The invention relates to a wire end processing method, in particular to an end processing method of a multi-strand excitation wire. The method comprises the following steps of: (1) peeling end insulation parts; (2) fixing end core wires into a whole; (3) cutting the end face into an inclined plane; (4) welding a copper pipe and the core wire end face; (5) connecting welding pieces; (6) inspecting; and (7) insulating a neck part. The method improves the reliability of conductive connection of the welding pieces and the multi-strand excitation wire.

Description

technical field [0001] The invention relates to a method for processing wire ends, in particular to a method for processing ends of multi-strand excitation wires. Background technique [0002] Excitation wire is also called Litz wire (Litz), which is wound or twisted into a multi-strand wire with a number of very thin mutually insulated copper wires, covered with an insulating sleeve. The word Litz comes from the German Litzendraht. Because the high-frequency skin effect and proximity effect of the excitation line have good performance, and the AC impedance and temperature rise are small, it becomes the best choice for high-frequency and high-current transmission lines, and is the best material for making high-power high-frequency inductance coils. [0003] For a frequency of 100kHz, the skin depth is 0.21mm, and the surface current density is much greater than the internal current density of the wire. The wire with a thicker diameter cannot be effectively used, and the heat...
