In this method, a ground wire is overlaid on a shield wire in cross. Next, overlapping portions of the shield wire and the ground wire are interposed between an upper resin tip and a lower resin tip By executing a first ultrasonic oscillation while inserting a projection of an ultrasonic horn into a through hole of the tip outside rinds of the wires are removed in the vicinity of the overlapping portions. Next, by arranging a low-melting metal and a resin piece on a contact between the braided wire and the core line and executing a second ultrasonic oscillation, the contact can be brazed with the mutual welding of the tips

Method of connecting covered wires

A connecting structure includes a shield wire,a ground wire,an upper resin tip,a lower resin tip,and a low-melting welding material,First, the ground wire,is overlaid on the shield wire,in cross. Next, overlapping portions of the shield wire,and the ground wire,are interposed between the resin tips,and,By oscillating the resin tips,and,with ultrasonic waves, respective outside rinds,of the wires,are removed in the vicinity of the overlapping portions. A braided wire,of the wire,is electrically connected with a core line,of the wire,and, simultaneously, the resin tips,and,are welded to each other to seal up the vicinity of a connecting part S,With the ultrasonic oscillation, a low-melting materials,is molten to flow into the connecting part S,so that the braided wire,of the wire,is joined to the core line,of the wire,through the molten material

Structure and method for connecting covered wires

In this method, a ground wire,is overlaid on a shield wire,in cross. Next, overlapping portions of the shield wire,and the ground wire,are interposed between an upper resin tip,and a lower resin tip,. By executing a first ultrasonic oscillation while inserting a projection,of an ultrasonic horn,into a through hole,of the tip,, outside rinds,of the wires,are removed in the vicinity of the overlapping portions. Next, by arranging a low-melting metal,and a resin piece,on a contact between the braided wire,and the core line,and executing a second ultrasonic oscillation, the contact can be brazed with the mutual welding of the tips

A connecting structure for covered wires is provided. At first, a shield wire 1 and a ground wire 2 are prepared. After overlaying the ground wire 2 on the shield wire 1 cross each other, respective overlapping portions of the wires 1, 2 are interposed between an upper resin tip 13 and a lower resin tip 14. Next, the upper and lower resin tips 13, 14 are oscillated with ultrasonic waves while compressing the upper and lower resin tips 13, 14 from the outside. Consequently, respective outside rinds 1d, 2b of the wires 1, 2 are molten for removal, so that a braided wire 1c comes into electrical contact with a core line 2a. The upper and lower resin tips 13, 14 have wire receiving grooves 13a, 14a formed on their butt faces. Each of the groove 13a, 14a has a semi-circular cross section of a diameter corresponding to the diameter of the shield wire 1. The upper resin tip 13 is provided, at an intermediate portion of the wire receiving groove 13a in the longitudinal direction, with a press part 13b for urging the ground wire 2 against the shield wire 1.
