ネルの絶縁方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electrical equipment, such as electric shavers and vacuum cleaners, in which electrical parts are housed in a synthetic resin housing.
For example, it relates to a method of insulating metal panels attached to the outer surface of housings for decoration.

る。The conventional electrical insulation method is as shown in FIG.
In order to maintain insulation between A and the mounting leg 5, an insulating paper 12 is inserted between the two, but the insulating paper 12 must be prepared as a separate part, and moreover, the insulating paper 12 may shift. There is a problem that electrical insulation cannot be maintained.

できるという効果がある。However, the method of electrically insulating electrical equipment according to the present invention is to store electrical components in a synthetic resin housing, and to expose the mounting legs of a metal panel that covers the outer surface of the housing to the inner surface of the housing. In the electrical equipment to be installed, the insulating rib interposed between the current-carrying part of the electrical component and the mounting leg of the metal panel is formed integrally with the housing, and is characterized by integrally protruding from the housing. Since electrical insulation is achieved by simply bending the insulating ribs, there is no need for insulating paper as in the conventional example, and there is no fear that the insulating paper will shift, ensuring electrical insulation.
