ている。In FIG. 1, reference numeral 1 denotes a capacitor case consisting of a metal case body 2 and a lid 3. As shown in FIG. 4 is a rivet that penetrates M3 as shown in FIG. 2, and is a protrusion having a height and width of approximately 0.1 to 0.8 mm inside the collar portion 5, and is provided at two or more locations. 7 is a terminal connected to the tip of the rivet 4. 8 is made of plastic as shown in Figure 3.
It is an insulating plate with a thickness of about 0.3 to 0.5 mm. Reference numeral 9 designates recesses provided in the insulating plate 8, each having a depth and a width of approximately 0.2 to 1.0 am, four or more recesses are provided, and the protrusions 6 of the rivet 4 are inserted into some of the recesses. Reference numeral 10 denotes a partition wall having a width of 1f1 or more and a height of 2 or more, which is provided between the holes 11 of the insulating plate 8 through which the rivets 4 pass, and is used to image creepage due to arc discharge. 1@- is a rubber backing installed between the insulating plate 8 and M3 and through which the rivet 4 is passed. 1+ is a bushing that contacts the rubber backing 10 and is penetrated by a rivet 4, insulating the terminal 7 from the backing 3.
上記実施例によれば、リベット４の突起６が絶縁板８の
四部９に挿入されているため、リベット４は絶縁板８に
固定され、回転を防止される。According to the above embodiment, since the projections 6 of the rivet 4 are inserted into the four parts 9 of the insulating plate 8, the rivet 4 is fixed to the insulating plate 8 and prevented from rotating.
なお、上記実施例では、絶縁板に凹部を設けたが、孔で

ものを用いる以外は他を同一とする。Next, the rotational torque of the rivet was measured for the above embodiment and the conventional example. As for the samples, the present invention example has the following: Rivet - Diameter 3FM (flange part 8rm) Protrusion provided on the rivet - Width and height both 0.5M Insulating plate - Material polybutylene terephthalate Thickness 1. 1
11j+ Four parts provided on the insulating plate - Width and depth both in order of 0.6 The conventional example is the same as the embodiment of the present invention except that the insulating plate without the four parts is used.
回転トルクの測定は、端子に回転力を加え回転を始める
までの値とする。The rotational torque is measured by applying rotational force to the terminal and taking the value until it starts rotating.
測定の結果、本発明実施例が７．９ｈ３であるのに対し
、従来例は３．８に９ｃｘとなり、前者の方が約２．２
倍以上の値が得られた。As a result of the measurement, the inventive example was 7.9h3, while the conventional example was 3.8 and 9cx, and the former was about 2.2
More than double the value was obtained.
