Abstract: Contact piece (63), which are used to establish therethrough electric connections between shielding areas on front and rear cases (41) and (43) making up an electronic equipment housing, are formed without bending so that they can be mounted on ribs (57, 59) of the cases (41, 43). A metal shield layer is coated all over the interior surface (55) of the rear case (43) and the partition wall (59) in a manner to surround a high-frequency oscillation circuit, and each contact piece (63) is held in a recess (61) formed in the partition wall (59). The contact pieces (63) are each produced by stamping a conductive sheet metal and has a resilient contact portion (75), which makes resilient contact with the shielding area (53) on the mating case by bending in direction perpendicular to that in which the contact piece (63) was stamped from the conductive sheet metal. The contact piece (63) can be formed simply by stamping and can be mounted in the recess (61) of about the same width as its thickness.

Abstract: An electrical junction box for connecting thereto a fuse, relay, unit, connector, etc., including a metal backed printed circuit board, which comprises a metal substrate such as aluminum; a heat conductive electrical insulating layer supported by the metal substrate; a plurality of circuits printed on the heat conductive electrical insulating layer, each of the plurality of circuits having a desired pattern.
