Abstract
Abstract A grounding disc which provides a common ground for an array of electrical contacts in a cylindrical connector includes a pattern of press fit holes which match the array of electrical contacts. Each press fit hole grippingly engages an electrical contact to establish a secure electrical and mechanical connection therewith without the use of solder or other mechanical fasteners.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
172 words
A grounding disc which provides a common ground for selected ones of an array of electrical contacts in an electrical connector comprising: an array of electrical contacts comprising a first group of electrical contacts and a second group of electrical contacts; a conductive disc having a pattern of press fit holes formed therein, the pattern of press fit holes matching the first group of electrical contacts, each press fit hole comprising a contact aperture which is dimensioned to grippingly receive one of the first group of electrical contacts whereby an electrical and mechanical connection is established between the grounding disc and the first group of electrical contracts without the use of solder or other mechanical fasteners; and a pair of reliefs formed in the conductive disc for each contact aperture, each relief comprising a notch formed in the conductive disc which intersects a contact aperture and allows the conductive disc to deform in order to receive an electrical contact, the pair of reliefs being positioned on opposite sides of the contact apertures.
Claim 2
Dependent Claim
172 words
A grounding disc which provides a common ground for selected ones of an array of electrical contacts in an electrical connector comprising: an array of electrical contacts comprising a first group of electrical contacts and a second group of electrical contacts; a conductive disc having a pattern of press fit holes formed therein, the pattern of press fit holes matching the first group of electrical contacts, each press fit hole comprising a contact aperture which is dimensioned to grippingly receive one of the first group of electrical contacts whereby an electrical and mechanical connection is established between the grounding disc and the first group of electrical contracts without the use of solder or other mechanical fasteners; and a pair of reliefs formed in the conductive disc for each contact aperture, each relief comprising a notch formed in the conductive disc which intersects a contact aperture and allows the conductive disc to deform in order to receive an electrical contact, the pair of reliefs being positioned on opposite sides of the contact apertures.
Claim 3
Dependent Claim
79 words
The grounding disc of claim 1 further comprising: an outer ring of contacts surrounding an inner ring of contacts, wherein the inner ring of contacts comprises the first group of electrical contacts and the outer ring of contacts comprises the second group of electrical contacts; and a central aperture formed in the conductive disc, wherein the central aperture provides passage for an electrical contact surrounded by the inner ring of contacts without making an electrical or mechanical connection therewith.
