Abstract
Abstract A connector device includes a fixed housing 30 fixed on a fixed member, a movable housing 20 mounted on a rotatable member and freely rotatably combined with the fixed housing, and a flexible flat transmission line 10,50 which serves to electrically or optically connect the fixed member to the rotatable member, which is wound in a spiral form and which is received in a space created by the fixed and movable housings. A clearance C₁ in an axial direction along the rotation shaft 20a of the movable housing between the flat transmission line and the movable housing, or between the flat transmission line and the fixed housing is set to be smaller in the intermediate portion of the flat transmission line than in at least one of the end portions at which the flat transmission line is fixed on the housings so as to suppress occurrence of unpleasant vibration sound caused by collision between the flat transmission line and the housings.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
A connector device comprising a flexible flat transmission line wound in a spiral form, a movable housing having an internal cylindrical shaft portion which acts as a rotation shaft and on which movable housing one end of the flat transmission line is fixed, and a fixed housing having an external cylindrical portion and on which fixed housing the other end of said transmission line is fixed, said movable and fixed housings being freely rotatably combined with each other to receive said flat transmission line, and said movable and fixed housings being rotatable relative to each other by a plurality of revolutions according to a tightening or loosening of the flat transmission line; characterised in that a clearance in an axial direction along said rotation shaft between said flat transmission line and said movable housing, or between said flat transmission line and said fixed housing is set to be smaller in the intermediate portion of the flat transmission line than in at least one of the end portions thereof.
Claim 2
Dependent Claim
168 words
A connector device comprising a flexible flat transmission line wound in a spiral form, a movable housing having an internal cylindrical shaft portion which acts as a rotation shaft and on which movable housing one end of the flat transmission line is fixed, and a fixed housing having an external cylindrical portion and on which fixed housing the other end of said transmission line is fixed, said movable and fixed housings being freely rotatably combined with each other to receive said flat transmission line, and said movable and fixed housings being rotatable relative to each other by a plurality of revolutions according to a tightening or loosening of the flat transmission line; characterised in that a clearance in an axial direction along said rotation shaft between said flat transmission line and said movable housing, or between said flat transmission line and said fixed housing is set to be smaller in the intermediate portion of the flat transmission line than in at least one of the end portions thereof.
Claim 3
Dependent Claim
54 words
A connector device according to claim 1, wherein each of said movable and fixed housings has an internal surface facing a corresponding one of side surfaces of said transmission line wound in the spiral form, and a projecting portion projecting towards said transmission line is formed on at least one of said internal surfaces.
Claim 4
Dependent Claim
31 words
A connector device according to claim 1 or 2, wherein said flat transmission line has a greater width in the intermediate portion than in at least one of the end portions.
Claim 5
Dependent Claim
49 words
A connector device according to any preceding claim, wherein each of said fixed and movable housings has an internal surface facing a corresponding one of side surfaces of said transmission line wound in the spiral form, and a spacer is mounted on at least one of said internal surfaces.
Claim 6
Dependent Claim
26 words
A connector device according to any preceding claim, wherein said flat transmission line is an electrically conductive line for transmitting an electric signal or electric power.
Claim 7
Dependent Claim
26 words
A connector device according to any of claims 1 to 4, wherein said flat transmission line is a light transmission line for transmitting a light signal.
Claim 8
Dependent Claim
42 words
A connector device according to any of claims 1 to 4, wherein said flat transmission line is a combination of an electrically conductive line for transmitting an electric signal or electric power and a light transmission line for transmitting a light signal.
Claim 9
Dependent Claim
97 words
A connector device comprising a housing including an outer housing and an inner housing rotatably engaged with said outer housing, and a flexible cable secured at one end to said outer housing and at the other end to said inner housing, said cable being wound about a shaft formed in said inner housing to form a spiral located in an annular region defined between said housings, wherein an axial clearance in said annular region between said cable and said housing is greater along an intermediate portion of said cable than along at least one end portion thereof.
Claim 10
Dependent Claim
97 words
A connector device comprising a housing including an outer housing and an inner housing rotatably engaged with said outer housing, and a flexible cable secured at one end to said outer housing and at the other end to said inner housing, said cable being wound about a shaft formed in said inner housing to form a spiral located in an annular region defined between said housings, wherein an axial clearance in said annular region between said cable and said housing is greater along an intermediate portion of said cable than along at least one end portion thereof.
