Abstract
Abstract Rotary connector for use with a small diameter flexible elongate member having electrical capabilities and having a proximal extremity with at least first and second spaced-apart conductive sleeves thereon. The rotary connector is comprised of a housing and at least first and second spaced-apart contact members mounted in the housing. The housing and the first and second contact members have passages therein through which the proximal extremity of the flexible elongate member can extend to place the first and second conductive sleeves in contact with the contact members. A clamping assembly means is carried by the housing for retaining the proximal extremity of the flexible elongate member in the housing while permitting rotation of the flexible elongate member with respect to the housing. The first and second contact members each have a base portion having proximal and distal sides. The base portion is provided with a hole therein and first and second sidewardly extending curved spring portions curved in opposite directions on the proximal side of the base portion. The first and second curved spring portions are in contact with each other along a line which is in general alignment with the hole in the base portion and are adapted to frictionally engage one of the conductive sleeves.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
A rotary connector for use with a small diameter flexible elongate member having electrical capabilities and having a proximal extremity with at least first and second spaced-apart conductive sleeves thereon comprising a housing, at least first and second spaced-apart contact members mounted in the housing, said housing and said first and second contact members having passages therein through which the proximal extremity of the flexible elongate member can extend to place the first and second conductive sleeves in contact with the contact members, means carried by the housing for retaining said proximal extremity of the flexible elongate member in the housing while permitting rotation of the flexible elongate member with respect to the housing, said first and second contact members each having a base portion having proximal and distal sides, said base portion being provided with a hole therein through which the proximal extremity of the flexible elongate member can extend, first and second sidewardly extending curved spring portions curved in opposite directions on one side of the base portion, said first and second curved spring portions being in contact with each other along a line which is in general in alignment with the hole in the base portion and being adapted to frictionally engage one of the conductive sleeves.
Claim 2
Dependent Claim
210 words
A rotary connector for use with a small diameter flexible elongate member having electrical capabilities and having a proximal extremity with at least first and second spaced-apart conductive sleeves thereon comprising a housing, at least first and second spaced-apart contact members mounted in the housing, said housing and said first and second contact members having passages therein through which the proximal extremity of the flexible elongate member can extend to place the first and second conductive sleeves in contact with the contact members, means carried by the housing for retaining said proximal extremity of the flexible elongate member in the housing while permitting rotation of the flexible elongate member with respect to the housing, said first and second contact members each having a base portion having proximal and distal sides, said base portion being provided with a hole therein through which the proximal extremity of the flexible elongate member can extend, first and second sidewardly extending curved spring portions curved in opposite directions on one side of the base portion, said first and second curved spring portions being in contact with each other along a line which is in general in alignment with the hole in the base portion and being adapted to frictionally engage one of the conductive sleeves.
Claim 3
Dependent Claim
47 words
A connector as in claim 1 wherein each of said curved portions is formed with side edges with a groove disposed between the side edges and in alignment with the hole to aid in centering the proximal extremity of the flexible elongate member in the contact member.
Claim 4
Dependent Claim
66 words
A device as in claim 1 wherein said means carried by the housing for retaining said proximal extremity of the flexible elongate member in the housing includes a collet having a distal extremity movable between clamping and release positions and assuming a release position when free, a collar engaging the collet and a spring means engaging the collar and urging the collet into a clamping position.
Claim 5
Dependent Claim
46 words
A connector as in claim 3 together with bearing means for supporting said collet in said housing, said bearing means having at least three outwardly extending protrusions formed thereon and means carried by the housing for receiving said protrusions and permitting said bearing to rotate therein.
Claim 6
Dependent Claim
54 words
A connector as in claim 1 wherein said housing includes an outer and an inner housing, said contact members having upper and lower tab portions, said inner housing having slot means for receiving said upper and lower tab portions for retaining said contact members in fixed positions and in alignment within the inner housing.
Claim 7
Dependent Claim
24 words
A connector as in claim 5 wherein said tab means extends out of the inner housing together with conductors secured to the tab means.
Claim 8
Dependent Claim
49 words
A connector as in claim 3 together with a nose piece mounted on the collar adapted to be engaged by fingers of the hand holding the rotary connector to depress the collar against the force of the spring means to permit the collet to move to a release position.
Claim 9
Dependent Claim
29 words
A connector as in claim 7 wherein said nose is provided with a camming surface adapted to engage the collet to cause it to open into the release position.
