【発明の属する技術分野】本発明は、金属ケースに取付
足を固定したコンデンサに関し、錆の発生防止と、取付
足を固定する作業の簡易化を目的としたものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capacitor in which a mounting foot is fixed to a metal case, and has an object to prevent rust and to simplify the work of fixing the mounting foot.
【０００２】[0002]

Ｕ字形の取付足を取着するには、はんだ付けが主として
用いられていた。2. Description of the Related Art Capacitors are installed in a variety of places and directions. For example, when the capacitor is mounted on a vertical wall or when vibration is applied, both sides of the capacitor are supported to support the weight of the capacitor body. U-shaped mounting feet attached to the surface and the bottom surface were used. In order to attach a U-shaped mounting foot to this capacitor, soldering has been mainly used.

だ付けを行う作業が必要であった。However, in the capacitor having such a structure, in order to attach the mounting foot to the bottom of the capacitor body so as to be symmetrical, a jig is used or the dimensions are measured and fixed at a predetermined position. After the temporary soldering, the work of performing the actual soldering was required.

た。[0004] Further, in the case of mounting in a place where corrosive gas is likely to be generated, such as in a chemical factory, if the mounting feet are soldered to the bottom of the capacitor, painting cannot be performed, and rust is generated, resulting in corrosion and consequently corrosion. There were inconveniences such as a hole in the case. After the process is reversed and only the bottom of the capacitor is painted, the mounting feet can be soldered. However, the painting is performed in two separate steps, which is inefficient and reduces the solder flux after soldering. During cleaning, there were problems such as damage to the coating on the bottom of the case.

発生しやすい場所に取り付けられる場合には、ケースに
穴があいたり、塗装が損傷する等の欠点があった。The above prior art has the following problems. That is, a jig is required to attach the mounting feet to the capacitor case,
Alternatively, since the mounting position must be determined by measuring the dimensions, the work efficiency is poor. In addition, when the case is installed in a place where corrosive gas or the like is likely to be generated, there are drawbacks such as a hole in the case and damage to the coating.

The present invention can efficiently attach a foot to a case and can be used in a place where corrosive gas is easily generated. Another object of the present invention is to provide a capacitor excellent in corrosion resistance without any trouble.
