ABSTRACT:
A connector is described which holds many contacts, and which can provide a direct ground connection to a contact, or provide a capacitive coupling between the contact and ground, in a rugged and simple construction. The connector includes a thick metal grounding plate attached to a metal shell that forms most of the outside of the connector. A dielectric layer lies on a face of the grounding plate and is covered by a metal overlayer to form a capacitor. A pin contact is connected to the overlayer by means of an insulator which has a plated-through hole engaged with the pin contact. The insulator also has a plated surface in facewise contact with the overlayer, to provide a capacitive coupling between the pin contact and the grounding plate. The grounding plate can have a hole plated with a softer material, and another pin contact can displace some of the softer material to lie in good contact with the grounding plate.
