Abstract
Abstract A stacking and orientation independent multiple contact plug and socket electrical connector has a central connector body with a "plug" extending outward on one face, and a "socket" recessed inward on an opposite face. The plug and socket are aligned along a common axis, but are on opposite faces of the central connector body. The plug is an electrically insulated post extending outward from the central connector body and having multiple electrically conductive circular contact rings encircling the post. The socket is a cylindrical recess into the central connector body designed to accept the plug of another similar connector. The socket has multiple electrical wiper contacts spaced along an electrically insulating inner wall of the recess for contacting to the circular contact rings of a post.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
173 words
A stacking and orientation independent plug and socket electrical connector comprising: a central connector body having at least first and second faces parallel and on opposite ends of said central connector body; a plug extending outward from said first face on said central connector body, said plug extending outward in a direction defining an axis through said plug and said central connector body; a socket recessed inward from said second face and extending into said central connector body, said socket recess aligned on said axis, and longitudinally spaced along said axis from said plug; a cable leaving said central connector body transverse to the axial alignment of said plug and socket; said plug comprising an electrically insulating material formed as a cylindrical post symmetric about said axis and having multiple electrically conductive circular contact rings encircling and longitudinally spaced along said cylindrical post; and said socket having multiple electrical wiper contacts longitudinally spaced along an inner wall of said socket recess for contacting to said circular contact rings of an inserted said plug.
Claim 2
Dependent Claim
173 words
A stacking and orientation independent plug and socket electrical connector comprising: a central connector body having at least first and second faces parallel and on opposite ends of said central connector body; a plug extending outward from said first face on said central connector body, said plug extending outward in a direction defining an axis through said plug and said central connector body; a socket recessed inward from said second face and extending into said central connector body, said socket recess aligned on said axis, and longitudinally spaced along said axis from said plug; a cable leaving said central connector body transverse to the axial alignment of said plug and socket; said plug comprising an electrically insulating material formed as a cylindrical post symmetric about said axis and having multiple electrically conductive circular contact rings encircling and longitudinally spaced along said cylindrical post; and said socket having multiple electrical wiper contacts longitudinally spaced along an inner wall of said socket recess for contacting to said circular contact rings of an inserted said plug.
Claim 3
Dependent Claim
51 words
A connector as in claim 1 wherein said cylindrical post is formed as a stepped cylinder having a first cylindrical portion closest to said first face of said central connector body having a relatively larger diameter than a second cylindrical portion further from said first face of said central connector body.
Claim 4
Dependent Claim
35 words
A connector as in claim 1 wherein said cylindrical post is formed as a multiply-stepped cylinder having multiple cylindrical portions of decreasing diameters located respectively further from said first face of said central connector body.
Claim 5
Dependent Claim
30 words
A connector as in claim 1 further comprising there being at least four said circular contact rings electrically connected within said central connector body to corresponding four said wiper contacts.
Claim 6
Dependent Claim
26 words
A connector as in claim 1 wherein said central connector body contains electrical components for interfacing said plug and said socket to conductors within said cable.
Claim 7
Dependent Claim
37 words
A connector as in claim 1 further comprising a detent ring encircling the base of said plug at least partially in contact with said first face of said central connector body from which said plug extends outward.
Claim 8
Dependent Claim
58 words
A connector as in claim 6 wherein said detent ring has multiple raised portions extending above the face of said central connector body from which said plug extends outward, said raised portions adapted for control of swiveling of said plug to a number of detent positions related to the position of said raised portions on said detent ring.
Claim 9
Dependent Claim
30 words
A connector as in claim 1 further comprising a capture probe projecting from the base of said socket recess inside said central connector body along said axis into said socket.
Claim 10
Dependent Claim
43 words
A connector as in claim 8 further comprising a capture probe recess formed in the outward face of said plug and extending along said axis into said plug for receiving a said capture probe when a said plug and said socket are coupled.
Claim 11
Dependent Claim
45 words
A connector as in claim 9 wherein said capture probe and said capture probe recess are formed in complementary keyed shapes which limit the span of rotation of said plug relative to a said socket after said plug is fully inserted into a said socket.
Claim 12
Dependent Claim
50 words
A connector as in claim 9 wherein said capture probe and said capture probe recess are formed in complementary keyed shapes which allow rotation of the plug and socket as said plug is inserted into a said socket, but locks them in a fixed orientation as full insertion is reached.
