Caulking is possible. Furthermore, caulking may be performed from any direction, increasing the degree of freedom in designing the caulking device. If a plate material is used for the connection terminal as in the past, it is necessary to perform caulking with a high load from a certain direction, and processing of a special shape is also required to prevent the terminal from being pulled out. Further, since the connecting terminal 5 has a circular cross section, positioning with an automatic insertion machine, insertion into a printed circuit board, cutting and bending after insertion can be performed reliably, and the reliability of automatic insertion can be improved.

性がより向上する。On the other hand, the connecting portions 3b, 3b of the terminal 3 may have a U-shaped cross section as shown in FIG. Furthermore, as shown in FIG. 6, a guide portion 3d may be formed whose tip expands outward. The guide portion 3d facilitates insertion of the connection terminal 5. Furthermore, if a material with low springback is used for each of the connecting portions 3b, the caulked portion will be stabilized, and contact reliability due to close contact will be further improved. If you form a plating layer of a low-melting point metal such as tin or solder on either or both of the terminals 2 and 5 in advance, and then heat the caulked part after caulking, the welding of the plating layer will reduce contact reliability. Improves sexual performance.
