Abstract
Abstract An electrical connector pivot hinge comprising jamb and door hinge portions each having a knuckle. The jamb knuckle is formed with a through bore, and the door knuckle is formed with a partial bore. Both bores are axially aligned. A pivot tube is located within both bores, and a sleeve bearing housed within the jamb knuckle envelopes the portion of the pivot tube located within the jamb knuckle bore to provide relative rotation between the knuckles. An electrical conductor extends through passageways formed in both the jamb and door hinge portions as well as the bores of the knuckles so that the hinge serves the dual functions of both a pivot hinge and an electrical connector.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
146 words
An electrical connector hinge comprising a hinge jamb portion having a knuckle and a hinge door portion also having a knuckle with the jamb knuckle being formed with a through bore and the door knuckle being formed with a partial bore with both bores being axially aligned, a pivot tube located within both bores and having a tight fit with the adjacent surface of the door bore and a loose fit with the adjacent surface of the jamb bore, a sleeve bearing housed within the jamb knuckle to envelope the portion of the pivot tube located therein and having a tight fit with the adjacent surface of the jamb bore and a loose fit permitting relative rotation with the adjacent and enveloped portion of the pivot tube, and an electrical cable extending through the passageway formed by the bore of the pivot tube within both knuckles.
Claim 2
Dependent Claim
146 words
An electrical connector hinge comprising a hinge jamb portion having a knuckle and a hinge door portion also having a knuckle with the jamb knuckle being formed with a through bore and the door knuckle being formed with a partial bore with both bores being axially aligned, a pivot tube located within both bores and having a tight fit with the adjacent surface of the door bore and a loose fit with the adjacent surface of the jamb bore, a sleeve bearing housed within the jamb knuckle to envelope the portion of the pivot tube located therein and having a tight fit with the adjacent surface of the jamb bore and a loose fit permitting relative rotation with the adjacent and enveloped portion of the pivot tube, and an electrical cable extending through the passageway formed by the bore of the pivot tube within both knuckles.
Claim 3
Dependent Claim
40 words
The inge of claim 1 including retaining means coupled to an end of the pivot tube adjacent the sleeve bearing to limit thereBy the axial movement of the pivot tube relative the sleeve thus locking the two hinge portions together.
Claim 4
Dependent Claim
28 words
The hinge of claim 1 in which the end of the pivot tube located within the door knuckle is slotted with the electrical cable passing through the slot.
Claim 5
Dependent Claim
39 words
The hinge of claim 1 in which a cap covers the end of the through bore of the jamb knuckle removed from the door knuckle to enclose thereby a central portion of the electrical cable within the hinge knuckles.
Claim 6
Dependent Claim
24 words
The hinge of claim 1 in which a central portion of the electrical cable is helically wound within the confines of the pivot tube.
Claim 7
Dependent Claim
39 words
The hinge of claim 1 in which the pivot tube is formed with a centrally disposed bearing flange housed within a counterbore located within the door knuckle to support thereby the hinge door portion on the jamb door portion.
Claim 8
Dependent Claim
37 words
The hinge of claim 6 in which the pivot tube is formed with a smaller diameter on one side of the bearing flange with the sleeve bearing loosely enveloping the smaller diameter portion of the pivot tube.
Claim 9
Dependent Claim
146 words
An electrical connector hinge comprising a first hinge portion having a knuckle and a second hinge portion also having a knuckle with the first knuckle being formed with a through bore and the second knuckle being formed with a partial bore with both bores being axially aligned, a pivot tube located within both bores and having a tight fit with the adjacent surface of the second bore and a loose fit with the adjacent surface of the first bore, a sleeve bearing housed within the first knuckle to envelope the portion of the pivot tube located therein and having a tight fit with the adjacent surface of the through bore and a loose fit permitting relative rotation with the adjacent and enveloped portion of the pivot tube, and an electrical cable extending through the passageway formed by the bore of the pivot tube within both knuckles.
Claim 10
Dependent Claim
146 words
An electrical connector hinge comprising a first hinge portion having a knuckle and a second hinge portion also having a knuckle with the first knuckle being formed with a through bore and the second knuckle being formed with a partial bore with both bores being axially aligned, a pivot tube located within both bores and having a tight fit with the adjacent surface of the second bore and a loose fit with the adjacent surface of the first bore, a sleeve bearing housed within the first knuckle to envelope the portion of the pivot tube located therein and having a tight fit with the adjacent surface of the through bore and a loose fit permitting relative rotation with the adjacent and enveloped portion of the pivot tube, and an electrical cable extending through the passageway formed by the bore of the pivot tube within both knuckles.
Claim 11
Dependent Claim
40 words
The hinge of claim 8 including retaining means coupled to an end of the pivot tube adjacent the sleeve bearing to limit thereby the axial movement of the pivot tube relative the sleeve thus locking the two hinge portions together.
Claim 12
Dependent Claim
23 words
The hinge of claim 9 in which the retaining means is a split ring located within a groove formed in the pivot tube.
