く採用されている。The method of connecting the base pin and the lead wire by the soldering method is to cut the lead wire inserted into the base pin near the end of the base pin and solder the end of the lead wire to the end of the base pin. Is. Further, the connection method of welding the lead wire to the base pin is a method of arc welding the lead wire inserted into the base pin and the tip of the base pin. However, in the base pin connected to the lead wire by such soldering or welding, a metal mass that is melted and solidified is formed at the tip of the base pin, and the pin tip shape becomes uneven, resulting in poor appearance. , The heat generated during soldering or welding may adversely affect the base pin. Therefore, recently, a connecting method by a caulking method has been widely adopted in which a lead wire is inserted into a cap pin and a tip portion of the cap pin is partially caulked to connect to the lead wire.

３と口金ピン２のかしめ接続が行われる。The base pin 2 has a cylindrical shape, a base end 2a thereof is fixed to the base 1, a front end 2b has a large thickness, and a straight lead wire insertion hole 4 is formed at the center thereof. First, the lead wire 3 is inserted from the inside of the base 1 into the base pin 2 as shown in FIG. Next, as shown in FIG. 10, the lead wire 3 protruding from the tip of the base pin 2 is cut near the tip of the base pin 2. Next, as shown in FIG. 11, the caulking connection jig 5 is inserted onto the base 1.
This jig 5 has a pin hole 6 into which the base pin 2 is inserted on the lower surface.
And a guide hole 7 extending in a perpendicular direction from a part of the pin hole 6, and a punch 8 for caulking is inserted into the guide hole 7.
When the jig 5 is inserted into the die 1, the punch 8 advances from the chain line position in FIG. 11 to the solid line position to immerse and deform a part of the outer periphery of the tip end of the die pin 2 held in the pin hole 6. The immersive deformed portion 9 bites into the lead wire 3, and the lead wire 3 and the base pin 2 are caulked and connected.

４が口金１０より外される。First, as shown in FIG. 3, the lead wire 12 is inserted into the mouthpiece pin 11 from the inside of the mouthpiece 10 to make the mouthpiece pin 1.
The lead wire 12 is made to project from the tip of 1. Next, as shown in FIG. 4, the caulking connection jig 14 is inserted onto the base 10. The jig 14 has a pin hole 15 penetrating vertically and a guide hole 16 extending in a direction orthogonal to a part of the pin hole 15. The base pin 11 is inserted in the lower portion of the pin hole 15, and the base is inserted into the guide hole 16. A punch 17 for crimping is inserted so as to be movable left and right. When the base pin 11 is inserted into the lower portion of the pin hole 15, the punch 17 faces a part of the outer periphery of the tip end of the base pin 11. When the jig 14 is inserted on the base 10,
The punch 17 moves forward to immerse and deform a part of the outer periphery of the tip of the mouthpiece pin 11, and this immersive deformed portion 18 causes the lead wire 12 to move.
Connected by caulking. After that, the punch 17 retreats and the jig 1
4 is removed from the base 10.

る。Next, as shown in FIG. 5, the tip of the lead wire 12 protruding from the tip of the base pin 11 is connected to the base pin 11.
Cut from a fixed place near the tip of. By this cutting, the length of the lead wire 12 from the caulking connection point with the mouthpiece pin 11 to the tip is made uniform, and the subsequent pushing of the lead wire 12 into the recess 13 is performed with an easy, reliable, and uniform shape. Close.

に達するまでの途中であってもよい。Next, as shown in FIG. 6, the tip of the lead wire 12 is pushed toward the tip recess 13 of the base pin 11. For example, the lead wire pushing rod 19 is arranged above the tip of the base pin 11 so as to be vertically movable. The rod 19 integrally has a projection 20 having a shape fitted in the recess 13 of the base pin 11 at the center of the lower end, and when the rod 19 is lowered, first, the projection 20 is formed.
Hits the tip of the lead wire 12 and pushes down the lead wire 12. Then, the lead wire 12 is axially compressed and deformed from the portion caulked and connected to the base pin 10 and pushed into the recess 13. This lead wire pushing is done by
Until the tip reaches the bottom of the recess 13, and then the rod 19 rises and separates from the base pin 11.
The lead wire is not necessarily pushed in until it reaches the bottom of the recess 13. If the tip of the lead wire 12 does not project from the tip of the base pin 11, it is in the process of reaching the bottom of the recess 13. Good.

要が無くなる。Therefore, the tip of the base pin 11 after connecting the lead wire has an appearance that the tip of the lead wire 12 can be seen at the bottom of the recess 13, and this appearance is almost the same as the appearance of the tip of the base pin 11 before connecting the lead wire. Is. As a result, the appearance of the base pin 11 after the lead wire connection is finished uniformly, and it becomes unnecessary to finish the tip of the base pin 11 by cutting and polishing after the lead wire connection.

る。According to the present invention, since the lead wire is connected to the pin terminal without protruding from the tip of the pin terminal, the appearance of the pin terminal before and after connecting the lead wire does not change and is uniform. As a result, the appearance of the pin terminals can be improved. Further, after the lead wire is connected to the pin terminal, a finishing process for adjusting the tip shape of the pin terminal is unnecessary, so that the connecting process between the pin terminal and the lead wire can be simplified and the workability can be improved. Further, the work of pushing the lead wire into the pin terminal is surely performed, and the lead wire pushing jig is not damaged.
