Abstract

PURPOSE:To give rigidity to the title insulating case made of a plastic material and to easily insert the insulating case into a can case by integrally molding the insulating case in a cup-like shape as an insulating member. CONSTITUTION:The title case 2 is formed in a cup-like cylinder having a bottom and side face sections by using such a plastic material as polypropylene having an insulating property and adequate rigidity. A can case 1 is formed in a cup- like cylinder having a bottom and side face sections by using aluminum and the case 2 having a U-shaped cross section is put in the case 1. Network parts 4 provided on a substrate 9 are housed in the can case 1 through the insulating case 2 in such a way that the substrate 9 is put in the D-edge section 1a of the case 1 and stopped by the recessed sections 11 of the case 1. The insulating case 2 is inserted between the parts 4 and case 1 and the parts 4 are housed in the case 2 in such a state where the parts 4 are dipped in a potting resin 10. Since the insulating case 2 has adequate rigidity, the case 2 can be easily inserted into the can case 1.
