Description of the Related Art Conventionally, a molded product made of a thermosetting resin or a thermoplastic resin such as epoxy, polypropylene, or polyphenylene sulfide is used as a terminal plate, and screw terminals for an electrolytic capacitor embedded and fixed at the time of molding the terminal plate include, for example, There is a technique as described in Japanese Utility Model Publication No. 60-11632. That is, as shown in FIG. 4, the main body 8 has a female thread 9 formed at the center thereof, and the female thread 9 passes through the main body 8 with the same screw diameter. The main body 8 is made of, for example, copper, copper alloy, aluminum alloy, steel or steel alloy, and is plated as necessary. As shown in FIG. 5, an aluminum rod 10 is
And pressed by a pair of dies 11 and 12 to form a rivet 13 shown in FIG. 4 to constitute a screw terminal.

する問題点があった。In a screw terminal having such a configuration, a male screw shorter than the length of the female screw portion 9 is usually used by being tightened to the outside of the female screw portion 9 of the main body 8, but the male screw is longer than the female screw portion. When the screw is forcibly tightened, the male screw comes into contact with the rivet portion 13 and the rivet portion 13 rotates together with the male screw, so that the connection state between the main body 8 and the rivet portion 13 becomes poor, and the contact resistance is reduced. However, there has been a problem that is changed or increased.

く、安定した特性を得ることができる。In the screw terminal for an electrolytic capacitor having the above configuration, when the external terminal is screwed in and attached, the length of the external terminal screw is longer than the length of the screw because it is formed on the screw terminal. Also, the male screw must be stopped by a small-diameter female screw formed from the other end, and the connection state is not affected by pushing or pushing the rivet portion connected to the other end. . . Therefore, the contact resistance between the main body and the rivet portion is not changed by this, and stable characteristics can be obtained.
