Abstract
Abstract A connector for mating a plurality of male and female electrical contacts has two tubular telescoping body portions and an annular collar surrounding them. A spring is confined inside the collar with its ends engaging the collar and a first body portion so as to yieldingly resist rotation of the collar relative to the first body portion. Axially opposed camming tabs on the collar and second body rotate the collar as the bodies are telescoped to a latching position of the tabs locking the connector bodies in mated contact position.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
155 words
An electrical connector comprising: first and second tubular connector bodies having telescopingly engaged body portions and axially mating electrical contacts; an annular collar encircling the telescoping body portions and rotatively held on the first body; a spring inside the collar, the ends of the spring being confined between the first body and the collar so as to yieldingly resist rotation of the collar relatively to the first body; axially opposed tabs on the collar and second body with opposed flaring cam surfaces cooperatively producing rotation of the collar relative to the second body as the bodies are telescoped to a mated contact position, the cam surfaces guiding the collar tab around the body tab; and the spring yielding as the collar is rotated by the cam tabs during contact mating, and the spring then rotating the collar tab to a latching position axially behind the body tab locking the connector bodies in mated contact position.
Claim 2
Dependent Claim
155 words
An electrical connector comprising: first and second tubular connector bodies having telescopingly engaged body portions and axially mating electrical contacts; an annular collar encircling the telescoping body portions and rotatively held on the first body; a spring inside the collar, the ends of the spring being confined between the first body and the collar so as to yieldingly resist rotation of the collar relatively to the first body; axially opposed tabs on the collar and second body with opposed flaring cam surfaces cooperatively producing rotation of the collar relative to the second body as the bodies are telescoped to a mated contact position, the cam surfaces guiding the collar tab around the body tab; and the spring yielding as the collar is rotated by the cam tabs during contact mating, and the spring then rotating the collar tab to a latching position axially behind the body tab locking the connector bodies in mated contact position.
Claim 3
Dependent Claim
29 words
A connector according to claim 1 wherein the collar and body tabs each are pie shaped with an opposing point from which the camming surfaces flare in opposite directions.
Claim 4
Dependent Claim
41 words
A connector according to claim 2 wherein the collar and body tabs each have a back surface remote from their point and extending in the direction of rotation, so that the back surfaces engage each other axially when in latching position.
Claim 5
Dependent Claim
19 words
A connector according to claim 3 wherein the camming surfaces and back surface of a tab intersect each other.
Claim 6
Dependent Claim
32 words
A connector according to claim 1 wherein the collar and first body have rotationally opposed stops mutually engaging to limit rotation of the collar by the spring relative to the first body.
Claim 7
Dependent Claim
54 words
A connector according to claim 5 wherein the stops are disposed normally to position the collar relative to the first body with the tab on the collar located with respect to the electrical contacts on the first body In a matching alignment for mating with the contacts and tab respectively of the second body.
Claim 8
Dependent Claim
21 words
A connector according to claim 6 wherein the spring urges the collar stops to a normal position striking the plug stop.
Claim 9
Dependent Claim
25 words
A connector according to claim 7 wherein the stops have opposed faces producing an audible snap when urged by the spring to an engaged position.
Claim 10
Dependent Claim
32 words
A connector according to claim 6 wherein the first and second body have a key and key way slidingly interfitting when the first and second bodies and collar are in matching alignment.
Claim 11
Dependent Claim
60 words
A connector according to claim 1 wherein the second body has circumferential ramp at the same radius as the collar tab, the ramp slanting across the path of the collar tab to cam the collar tab, collar and first body apart and out of engagement with the second body when the collar is manually rotated relative to the mated bodies.
Claim 12
Dependent Claim
20 words
A connector according to claim 10 wherein the spring returns the collar to matching alignment when the bodies are disengaged.
Claim 13
Dependent Claim
28 words
A connector according to claim 1 wherein the collar and second body have longitudinally matching index marks indicating matching alignment of the first and second body and collar.
Claim 14
Dependent Claim
17 words
A connector according to claim 1 wherein the first and second bodies are a plug and socket.
Claim 15
Dependent Claim
15 words
A connector according to claim 1 wherein the spring is coiled around the first body.
Claim 16
Dependent Claim
17 words
A connector according to claim 14 wherein the spring is a formed of round wire spring metal.
