Abstract
Abstract An electrical connector assembly having means for protecting its contacts from adverse voltage surges includes protectively terminating one terminal of a silicon diode within a notch formed in the contact and the other terminal with a conductive sleeve encircling the contact body but spaced therefrom. The conductive sleeve is in releasable engagement with a plurality of conductive spring fingers which are integral with a conductive grounding plate whereby a ground path is established between the connector shell and the contact without stressing the diode or its terminations.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
An electrical connector member comprising a conductive connector shell, a conductive grounding plate in the shell and in electrical contact therewith, said plate having a plurality of integral conductive spring fingers extending therefrom, an opening extending through the plate, a conductive contact body having a longitudinal axis and mounted in the opening, an electrical component mounted on the side of the contact body and connecting means for electrically connecting the electrical component to the plate, said connecting means comprising a conductive ground sleeve encircling said contact body but spaced therefrom and releasably engaging said integral conductive spring fingers of said conductive grounding plate, and said electrical component having a pair of conductive terminals being electrically and mechanically connected to said ground sleeve and said contact body, respectively, said ground sleeve being longitudinally offset from and not being in direct mechanical contact with said electrical component.
Claim 2
Dependent Claim
145 words
An electrical connector member comprising a conductive connector shell, a conductive grounding plate in the shell and in electrical contact therewith, said plate having a plurality of integral conductive spring fingers extending therefrom, an opening extending through the plate, a conductive contact body having a longitudinal axis and mounted in the opening, an electrical component mounted on the side of the contact body and connecting means for electrically connecting the electrical component to the plate, said connecting means comprising a conductive ground sleeve encircling said contact body but spaced therefrom and releasably engaging said integral conductive spring fingers of said conductive grounding plate, and said electrical component having a pair of conductive terminals being electrically and mechanically connected to said ground sleeve and said contact body, respectively, said ground sleeve being longitudinally offset from and not being in direct mechanical contact with said electrical component.
Claim 3
Dependent Claim
40 words
The connector member as recited in claim 1 wherein said plurality of spring fingers extend from said ground plate and converge together to releasably engage the outer periphery of said ground sleeve of the contact body disposed in the opening.
Claim 4
Dependent Claim
22 words
The connector member as recited in claim 1 wherein an insulator sleeve is interposed between the contact body and the ground sleeve.
Claim 5
Dependent Claim
66 words
The connector member as recited in claim 3 wherein the contact body is generally cylindrical and includes a notch therein forming a supporting surface, said ground sleeve is generally cylindrical and includes barbs which seat against opposite ends of the insulator sleeve and an elongated tab which extends inwardly to the supporting surface, and said terminals are non-releasably connected to the supporting surface and the tab.
Claim 6
Dependent Claim
35 words
The connector member as recited in claim 4 wherein said terminals are substantially flat with their transverse width being substantially equal to the width, respectively, of the ground sleeve and support surface to which connected.
Claim 7
Dependent Claim
32 words
The connector member as recited in claim 4 wherein conductive electrical epoxy electrically and mechanically secures said terminals and electrical component within the notch, to said contact body and said ground sleeve.
Claim 8
Dependent Claim
16 words
The connector member as recited in claim 1 wherein said electrical component comprises a semiconductor diode.
