This invention relates to a novel device for sufficiently firmly mounting a cylindrical, electronic circuit component part such as an electrolytic capacitor on a chassis without difficulty, which permits efficient assembly of the electrical circuit component part and provides increased strength against vibrations etc.
As shown in the art, a large-capacity electrolytic capacitor is cylindrically formed having a diameter of several centimeters or more. The capacitor is mounted with respect to a chassis and electrically connected to the other electrical circuit component parts. As the electrolytic capacitor is larger in size and heavier in weight, it is sufficiently mechanically firmly mounted with respect to the chassis.
The electrolytic capacitor mounting member is constructed mainly of a metal band such as aluminum. For example, two mounting pieces are formed integral with the side of the band such that they project outwardly. That is, the metal band is wrapped around the outer periphery of the electrolytic capacitor with one end portion of the metal band connected by a screw to the other end portion of the metal band. The metal band wrapped around the capacitor is mounted by connecting the mounting pieces by screws to a chassis. In this case, however, it is necessary to first tighten the metal band around the outer periphery of the electrolytic capacitor and then screw the mounting pieces of the metal band on the chassis. Therefore, the mounting operation becomes cumbersome, lowering the efficiency of the device mounting operation. Moreover, since the metal band is wrapped around the outer periphery of the electrolytic capacitor and then one end portion of the metal band is screwed to the other end portion of the metal band, the screw tends to loosen. When, in particular, mechanical vibration is applied to the screwed portion, the screw tends to loosen. In an electronic apparatus mounted, for example, on the rolling stock, aircraft etc. care must be exercised to mount such an electrical circuit component part.
