Abstract
In this method, a ground wire 2 is overlaid on a shield wire 1 in cross. Next, overlapping portions of the shield wire 1 and the ground wire 2 are interposed between an upper resin tip 13 and a lower resin tip 14. By executing a first ultrasonic oscillation while inserting a projection 7a of an ultrasonic horn 7 into a through hole 13b of the tip 13, outside rinds 1d, 2b of the wires 1, 2 are removed in the vicinity of the overlapping portions. Next, by arranging a low-melting metal 15 and a resin piece 16 on a contact between the braided wire 1c and the core line 2a and executing a second ultrasonic oscillation, the contact can be brazed with the mutual welding of the tips 13, 14.
Claims7
A method of connecting conductors of covered wires to each other, the method comprising:
- a first process including:
- preparing a first covered wire having a first conductor covered with an insulating cover and a second covered wire having a second conductor covered with another insulating cover;
- overlaying the second covered wire on the first covered wire so as to cross each other;
- putting overlapping portions of the first and second wires between an upper resin tip and a lower resin tip;
- and
- melting and removing the insulating covers of the first and second wires in the vicinity of the overlapping portions by a first ultrasonic oscillation;
- and
- a sequential second process including:
- setting a brazing metal on a contact between the first conductor and the second conductor, the contact being exposed by removing the insulating covers of the first and second wires;
- and
- melting the brazing metal to braze the contact by a second ultrasonic oscillation.

- and
- applying a second ultrasonic oscillation on the upper and lower resin tips while pressurizing them from the outside, thereby melting the brazing metal to braze the contact and also mutually welding the upper and lower resin tips to each other to seal up the circumference of the contact by the welded resin tips.
