ABSTRACT:
An electrical coupling is provided which has a dielectric body with numerous contact-holding holes, which provides electromagnetic shielding between contacts in a simple and low cost construction. The body (20, FIG. 3) has through holes extending between its opposite faces, and has a metal plating (34) which covers the walls of the holes as well as at least a portion of a face to interconnect all of the hole platings. A plurality of dielectric bushings (54, 56) lie in many of the holes to prevent contacts (36) in the holes from touching the plating on the walls of the holes. At least one of the holes not occupied by one of the bushings, holds a metal grounding device (60) securely connected to the plating on the hole wall and forming a contact for connecting to a grounded terminal (16G).
