Patent Images
1. A molded housing for an electronic circuit comprising:
- a polymer molding having bottom and side walls defining a cavity;
a conductive insert in the cavity for EMI protection of the circuit, the conductive insert being defined by a metal stamping lining the cavity and including circuit board mounting means comprisingtabs extending into the cavity normal to the side walls, anddeformable posts projecting from the tabs adapted to engage and retain a circuit board; and
a connector integral with the molding including an array of terminal pins extending through one of the side walls for connection to the circuit.

Abstract
A metal shield is stamped from sheet metal into a box shape and tabs are bent up from the housing walls, and posts are extruded from the tabs. The shield is then insert molded into a plastic housing. A connector shroud is molded on one side of the housing and apertures for terminal pins are also formed during molding. Pins are pressed into the aperture and the ends bent up for circuit board connection. Metal bushings insert molded into ears on the housing provide mounting lugs. The tabs are supports for a circuit board and the posts extend through holes in the circuit board and are upset to retain the board without screws.
