Abstract
Abstract An RF connector for printed circuit boards, strip line cards, printed circuit cables and the like, particularly for microsystem packaging. The connector is adapted to be mounted on a baseboard or strip line card provided with a ground plane. A copper shield is mounted on the body of the connector with individual insulated tabs or fingers and one or more uninsulated tabs or fingers inserted behind the contacts of the connector. The lower edge of the shield is attached to a ground contact or directly to the baseboard or card. The impedance of a signal circuit can be varied by varying the length of the insulated tab that is in close proximity to the signal contact. Preferably the shield is provided with an insulating coating on one side so that electrical contact can be made with a ground contact of the connector by merely folding over the tip end of the grounding tab.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
In an electrical connector comprising an insulating connector body provided with an inner recess adapted to receive a plug-in member and a row of interspersed signal and ground contacts in said recess each having terminal portions projecting from said connector body, the improvement comprising a grounded metallic shield having a main section outside said connector body and integral tabs or fingers extending into said recess in close proximity to said contacts, one of said tabs or fingers being disposed in electrical contact with said ground contact.
Claim 2
Dependent Claim
86 words
In an electrical connector comprising an insulating connector body provided with an inner recess adapted to receive a plug-in member and a row of interspersed signal and ground contacts in said recess each having terminal portions projecting from said connector body, the improvement comprising a grounded metallic shield having a main section outside said connector body and integral tabs or fingers extending into said recess in close proximity to said contacts, one of said tabs or fingers being disposed in electrical contact with said ground contact.
Claim 3
Dependent Claim
30 words
An electrical connector according to claim 1, in which the grounded shield is provided with an insulating coating on the tabs or fingers adjacent the signal contacts in said recess.
Claim 4
Dependent Claim
37 words
An electrical connector according to claim 1, in which said tabs or fingers on the grounded metallic shield are selectively coated with insulation in certain areas to provide conductive contact with some of the connector contacts only.
Claim 5
Dependent Claim
35 words
An electrical connector according to claim 1, in which the surface of at least one of said tabs or fingers is disposed in intimate contact with the surface of a signal contact but insulated therefrom.
Claim 6
Dependent Claim
59 words
An electrical connector comprising a row of interspaced ground and signal contacts, a metallic ground plate having integral tabs or fingers in physical contact with the respective connector contacts, said tabs or fingers being provided with an insulating coating on the areas where the tabs or fingers engage the signal contacts, and a ground connection for said ground plate.
Claim 7
Dependent Claim
59 words
An electrical connector comprising a row of interspaced ground and signal contacts, a metallic ground plate having integral tabs or fingers in physical contact with the respective connector contacts, said tabs or fingers being provided with an insulating coating on the areas where the tabs or fingers engage the signal contacts, and a ground connection for said ground plate.
Claim 8
Dependent Claim
126 words
An electrical connector comprising an insulating connector body provided with an inner cavity or recess, a plurality of resilient contact members mounted in said cavity or recess and adapted to cooperate with the terminal contacts of a printed circuit component inserted in said cavity or recess, said contact members having integral terminal portions projecting from the connector body for mounting the connector on a second circuit component having a ground plane, and a metallic grounding shield on the outside surface of said insulating connecting body and provided with integral tabs or fingers projecting inside said cavity or recess in a position to engage the surface of the respective contact members, said tabs or fingers having an insulating coating on the surface engaging said connector contact members.
Claim 9
Dependent Claim
126 words
An electrical connector comprising an insulating connector body provided with an inner cavity or recess, a plurality of resilient contact members mounted in said cavity or recess and adapted to cooperate with the terminal contacts of a printed circuit component inserted in said cavity or recess, said contact members having integral terminal portions projecting from the connector body for mounting the connector on a second circuit component having a ground plane, and a metallic grounding shield on the outside surface of said insulating connecting body and provided with integral tabs or fingers projecting inside said cavity or recess in a position to engage the surface of the respective contact members, said tabs or fingers having an insulating coating on the surface engaging said connector contact members.
Claim 10
Dependent Claim
33 words
An electrical connector according to claim 6, in which one of the tabs or fingers is folded over at the tip to make electrical contact with a predetermined one of the contact members.
