Abstract

PURPOSE:To improve the heat dissipating characteristic, the insulating characteristic and the workability of a capacitor fixing apparatus by bringing the inner surface of an insulating bushing into contact with the outer circumferential surface of a capacitor so that a protuberance can engage with a furrow or an indentation, whereby the capacitor is fixed to the insulating bushing. CONSTITUTION:A capacitor 2 is inserted along the internal circumferential surface of a barrel portion 6a of an insulting bushing 6, so that the outer circumferential surface of a metal case 3 comes, or substantially comes, into contact with the internal circumferential surface of the barrel portion 6a. Concurrently, a protuberance 6e formed on an arm 6d of the insulating bushing 6 is engaged with a furrow 3a of the metal case 3. The protuberance 6e is forced against the furrow 3a under the resilience of the arm 6d, thereby fixedly attaching the capacitor 2 to the insulating bushing 6. Thus, it is possible to improve an insulating characteristic between the capacitor 2 and a chassis 1 and a heat dissipating effect of the bushing owing to at least partial removal of the barrel portion. In addition, since the fixing of the capacitor is easy it is possible to improve the workability of the insulating housing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capacitor mounting device and a capacitor mounting method.

[0002]

2. Description of the Related Art Conventionally, when a large-sized capacitor such as an aluminum electrolytic capacitor is mounted on a chassis of electric equipment, electronic equipment, etc., an aluminum case is provided with an insulating tube as shown in FIG. 15 in order to insulate the capacitor from the chassis. After being covered with, the band-shaped mounting member is generally screwed to the capacitor, and the band-shaped mounting member is generally mounted and fixed to the chassis.

Further, when a capacitor using a medium-sized aluminum case is mounted on a chassis of electric equipment, electronic equipment, etc., since a mounting device cannot be soldered to the aluminum case, a belt-shaped mounting as shown in FIGS. Attach the capacitor to the chassis using the metal fittings or the hook fittings as shown in FIG.
As shown in FIG. 8, it is common to mount and fix a capacitor using a synthetic resin case in which mounting feet are integrally molded to the chassis.

[0004]

However, when mounting the capacitor on the surface of the chassis using the mounting device described above,

(A) In the mounting method using the strip-shaped mounting metal fitting shown in FIG. 15, it is necessary to mount it on the capacitor in advance with screws. At this point, the vertical positional relationship between the strip-shaped mounting metal fitting and the capacitor body, and the terminal of the capacitor. It is easy to make mistakes because it is necessary to work to determine the positional relationship between the and belt-shaped mounting brackets in the rotating direction. Further, when the capacitor is mounted while being insulated from the chassis, it is necessary to cover the capacitor with an insulating tube or to mount and fix the capacitor to the band-shaped mounting bracket via a band-shaped insulator.

(B) The mounting method using the strip-shaped mounting bracket shown in FIG. 16 has a function of mounting the strip-shaped mounting bracket on the capacitor and a function of mounting and fixing the capacitor on the chassis via the strip-shaped mounting bracket. Although it also serves as a screw, the capacitor floats from the chassis due to vibration or shock after installation, or it rotates around the installed screw. Therefore, it can be applied only to a relatively small capacitor. Also, regarding the problem of insulation between the chassis and the capacitor,
It is the same as the above (a).

(C) The mounting method using the hook mounting metal fitting shown in FIG. 17 has a structure in which the mounting metal fitting is pulled to the upper winding part of the capacitor, so that insulation between the capacitor and the chassis is difficult. Therefore, it is necessary to interpose an insulating plate between the capacitor and the chassis. Also, if the chassis is thin, the strength will be weak, and the chassis will be distorted by the hook mounting bracket.

(D) When the capacitor is mounted on the surface of the chassis, since the center of gravity of the capacitor is far from the chassis surface, even if the large capacitor is mounted horizontally or vertically, the force or vibration is laterally applied. If added, some kind of support is needed on top of the capacitor case.

(E) In the method of covering the capacitor with the chassis by covering the capacitor with an insulating tube or enclosing the capacitor in an insulating case, heat dissipation of the capacitor is hindered. It must be used in a place where the ambient temperature is lower than when an insulating case is not used. There was a problem such as.
