産コストも高くなるという欠点があつた。 When attaching a conventional cylindrical capacitor by inserting it into a through hole in a board, the capacitor is designed to prevent the capacitor from falling out of the through hole and to facilitate conductive connection with the board as shown in Fig. 1. , has the shape and structure as shown in FIG.
In other words, what is shown in FIG.
An eyelet-shaped metal terminal 4 having a flange portion 5 is fitted onto the terminal 4, and the terminal 4 and the electrode 3 are electrically connected to each other. When inserting this into the through hole of the board, the flange 5 functions as a locking piece to prevent it from coming off and a terminal for conductive connection with the board. However, since this method uses eyelet-shaped metal terminals 4, the number of parts not only increases and costs increase, but also requires work to fit the terminals 4 onto the capacitor and conductive connection, which increases production costs. The drawback was that it was expensive.

However, in this case, the forming of the dielectric 1 is
For example, since it must be performed using a powder molding mold, the mold must be changed every time the shape of the dielectric material changes, and the complexity of mold management and production makes the product cost extremely high. There was a drawback.
本考案は上記従来の欠点を除去せんとしてなさ

In other words, the flat part Z
By forming this, a major diameter portion and a minor diameter portion are formed at one open end, and this major diameter portion is formed to be larger than any diameter of the other open end.

すればよいのである。 In order to attach the cylindrical capacitor constructed in this way to a substrate, it is sufficient to simply insert it into the through hole 22 of the substrate 21 as shown in the fifth figure. In this case, both ends of the long diameter part of the flat part Z formed at one open end of the cylindrical capacitor act as locking pieces to prevent it from coming off from the board 21, and the cylindrical capacitor is held in a predetermined position. will be done. In this state, the substrate 21 and the dielectric 1
1 and the electrode 13 on the outer peripheral surface may be electrically connected by soldering or the like.

とができる。 Next, one open end of each divided dielectric is pressed radially from both sides to form a flat portion.
In this case, the dielectric still has plasticity, so
A flat portion can be easily formed with a slight pressing force.

In particular, the shape of the dielectric may be cylindrical or prismatic, and the shape of the electrodes may also be arbitrary. Further, when the cylindrical capacitor of the present invention is used as a feedthrough capacitor, a feedthrough terminal (not shown) may be inserted into the inner hole of the dielectric material and fixed by being electrically connected to the inner surface electrode.
Further, the shape of the flat portion is not limited to that shown in the drawings, and may be any shape as long as it can be locked to prevent the cylindrical capacitor from falling out when attached to the board.
