Abstract
Abstract A completely shielded metallized connector block for use in multiple circuit modules of an electronic device. Electrical communication between the circuit boards is effected by an array of metallic pins which run through the blocks. The metallization on the nonconductive blocks can be held at ground or at a constant potential to increase the shielding between pins as well as maintaining voltage and ground planes at constant levels throughout the modules. The metallization is insulated from the pins and circuit boards by nonconductive bushings inserted in holes in the blocks. In one embodiment, the metallization consists of copper and solder plating and the blocks are constructed of liquid crystal polymer.
