TERMINAL CONNECTION METHOD FOR LITZ WIRE AND LITZ WIRE WITH TERMINAL FITTING
First Claim
1. A terminal connecting method for a litz wire for electrically connecting a terminal metal fitting to a litz wire, the terminal metal fitting having a pressure fixing part having a cylindrical shape, the litz wire being obtained by twisting together a plurality of strands each composed of a conducting body and an insulation film provided on an outer peripheral surface of the conducting body, the method comprising:
- removing the insulation film by a predetermined length from one end of the litz wire;
inserting to the pressure fixing part a terminal part of the litz wire from which the insulation film is removed;
compressing a first portion of the pressure fixing part with a first compression force to cause plastic deformation of an entirety of the pressure fixing part, and to temporarily fix the terminal part of the litz wire to the pressure fixing part;
compressing a second portion of the pressure fixing part with a second compression force greater than the first compression force to locally cause plastic deformation of the pressure fixing part and the litz wire, the second portion being a part of the first portion; and
pouring molten solder from a front end side of the pressure fixing part to firmly fix the litz wire to the terminal metal fitting.
