The end faces of 1, 102 are abutted, and the abutted portion is irradiated with laser light to melt the wire ends. Then, as shown in FIG. 7, both wires 101 and 102 are pulled back from the state where the melt 103 is spherical due to the surface tension as shown in FIG.

１１４をカシメ付けて接合する方法も提案されている。On the other hand, in the metal wire connecting method disclosed in Japanese Unexamined Patent Publication No. 10-201704, as shown in FIG. 9, the end faces of a wire 111 formed by bundling a plurality of element wires and a wire 112 made of a single wire are butted against each other. The metal wires are joined to each other by the joint 113 by laser welding by irradiating the abutting portion with a laser, brazing, soldering, or bonding with an adhesive. Further, as shown in FIG. 10, a method has also been proposed in which a metal connection pipe 114 is covered over both butted portions of a metal wire to be connected, and the connection pipe 114 is caulked and joined.

う問題があった。In laser welding, soldering, brazing, and joining with an adhesive, if the material properties of the metal wires are compatible with each other, the connection processing is possible. However, if the material has a very strong affinity with substances in the air (oxygen, nitrogen, hydrogen, etc.) such as Ni-Ti (nickel titanium) alloy, a strong oxide film is formed on the surface, It becomes very difficult to join each other. In addition to that, there is a problem in that the portion of the metal wire that has been heated by laser irradiation and becomes high in temperature becomes brittle and the material strength of the metal wire decreases.

っていた。Further, in soldering, brazing, and joining of adhesives, when a large amount of the melting material or the adhesive is adhered to the joined portion and an extra portion is left, the extra portion is replaced with another wire. The swelling is larger than that of the portion, and polishing work is required to restore the connection portion to a desired shape having a uniform diameter.

った。Further, in the conventional metal wire connecting method, the smaller the diameter of the wire to be connected, the more difficult it is to position the ends of the wires to abut each other.
In particular, when used as a wire member of an instrument to be inserted into a channel of an endoscope as disclosed in Japanese Patent Laid-Open No. 10-201704, if the connecting pipe is simply crimped, the end of the connecting pipe becomes a sharp edge. The remaining edge portion causes a catch when the wire member is inserted into the channel of the endoscope. Further, the edge portion comes into contact with the inner surface of the channel of the endoscope, thereby damaging the channel tube member. For this reason, it is necessary to grind to a desired shape that is smooth and has no sharp edges.

る。After caulking, as shown in FIG. 5, the edge portion 11 of the metal pipe 3 is irradiated with laser light from the laser device 12 to melt the edge portion 11. At this time, if the laser light hits the wire element wire, the metal wire element wire may be broken. Therefore, the laser light is applied only to the edge portion 11 of the metal pipe 3. Then, as shown in FIG. 6, the melted edge portion 13 is in a chamfered state in which the edge portion 13 is chamfered cleanly and has a gentle shape.

The edge part after melting can be chamfered more neatly. This laser irradiation operation is performed on both ends of the metal pipe 3. Further, if the metal wires 1 and 2 and the metal pipe 3 have similar material characteristics, a part of the melted metal pipe 3 easily penetrates into the gap between the metal wire strands, and the metal wire 1, Since the contact area between the metal pipe 2 and the metal pipe 3 increases, stronger connection strength can be secured.

Since the metal pipe 3 is crimped to the metal pipe 3 and the end face of the metal pipe 3 is melted and connected to the metal wires 1 and 2, even the metal wires 1 and 2 having a particularly strong oxide film can be reliably joined. Further, since the edge portion of the metal pipe 3 is chamfered, it is possible to reduce catching and damage to the inner surface of the pipe even when the metal pipe 3 is inserted into a thin pipe, for example.
