た。 Due to the reset phenomenon of capacitors, a certain level of re-electromotive voltage is generated, which can cause accidents such as electric shock, but in order to prevent such accidents, conventional
As shown in the figure, a cylindrical discharge resistor 3 made of carbon or the like is connected between terminals 1 and 2 provided on the lid. However, when discharging resistor 3 is connected to case 4,
If the capacitor 5 is installed outside the case, it will be difficult to attach the capacitor 5 to the equipment.In particular, if the lead wires 6 and 7 of the discharge resistor 3 are made long and moved away from the case 4, they will easily come into contact with other electronic components, which may cause equipment failure. It also becomes. Moreover, when the discharge resistor is built into the case, it not only becomes difficult to manufacture, but also has the drawback that the case becomes large and prevents miniaturization of the device.
本考案は、以上の欠点を改良し、製造が容易で

び１３が接続されている。 In FIG. 2, numeral 11 is a capacitor element formed by laminating and winding aluminum electrode foil together with a separator, or by winding metallized paper, etc., from which lead wires 12 and 13 are drawn out. Reference numeral 14 denotes a cylindrical case made of metal such as aluminum and housing the capacitor element 11 therein. 15 is a lid body for sealing the open end of the case 14;
The material is made of a synthetic resin such as polypropylene or polyethylene mixed with a conductive material such as carbon, and the peripheral edge is stepped and an elastic body 16 such as rubber is fixed with adhesive, and a case is attached to this elastic body 16. 1
The open end 17 of 4 bites in and is sufficiently sealed. The resistance value of the lid body 15 is set to about several tens to several hundreds of kilohms by adjusting the content of the conductive material. 18 and 19 are this lid body 15
These terminals penetrate through the terminals, and are connected to lead wires 12 and 13, respectively.
