Abstract
Abstract A connector device which connects a rotatable member and a fixed member, for example, of a vehicular steering system, electrically or optically, by means of a belt-shaped transmission line (11) coiled in a convolution. The transmission line (11) is contained in a housing assembly (12) which is composed of a movable housing (13), mounted on the rotatable-member side, and a stationary housing (14) on the fixed-member side. A vibration restraining member (40) is interposed between one side edge of the coiled transmission line and a flange portion (16) of the movable and/or stationary housing. The restraining member serves to restrain the transmission line from moving crosswise, thereby preventing production of vibration and noise. Preferably, a resilient tongue, which extends along the transmission line, is fixed to an inner cylinder portion (15) to which an inner coil-end portion of the transmission line is fixed. In such an arrangement, the transmission line is prevented from bending sigmoidally when it is loosened.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
181 words
A connector device having a transmission line coiled in the shape of a convolution, and housing means containing said transmission line, said housing means including a stationary housing attachable to a fixed member and a movable housing attachable to a movable member, said stationary housing being fixedly fitted with one end of said transmission line and having a first flange portion facing one side edge of said coiled transmission line, and said movable housing being fixedly fitted with the other end of said transmission line and having a second flange portion facing the other side edge of said coiled transmission line, so that said movable housing can make a plurality of revolutions relative to said stationary housing, said connector device comprising vibration restraining means disposed in at least one of spaces which are defined between said one side edge of said transmission line and said first flange portion, and between said other side edge of said transmission line and said second flange portion, whereby said transmission line is pressed in the transverse direction thereof so as to be restrained from vibrating.
Claim 2
Dependent Claim
181 words
A connector device having a transmission line coiled in the shape of a convolution, and housing means containing said transmission line, said housing means including a stationary housing attachable to a fixed member and a movable housing attachable to a movable member, said stationary housing being fixedly fitted with one end of said transmission line and having a first flange portion facing one side edge of said coiled transmission line, and said movable housing being fixedly fitted with the other end of said transmission line and having a second flange portion facing the other side edge of said coiled transmission line, so that said movable housing can make a plurality of revolutions relative to said stationary housing, said connector device comprising vibration restraining means disposed in at least one of spaces which are defined between said one side edge of said transmission line and said first flange portion, and between said other side edge of said transmission line and said second flange portion, whereby said transmission line is pressed in the transverse direction thereof so as to be restrained from vibrating.
Claim 3
Dependent Claim
31 words
A connector device according to claim 1, wherein said vibration restraining means is a ring-shaped plate, having a resilient member formed on that surface thereof which faces the adjacent flange portion.
Claim 4
Dependent Claim
29 words
A connector device according to claim 2, wherein said resilient member is formed by bending at least one of the inner and outer peripheral edges of said ring-shaped plate.
Claim 5
Dependent Claim
56 words
A connector device according to claim 1, 2 or 3 wherein said stationary housing includes an inner cylinder portion fixedly fitted with said one end of said transmission line, as an inner coil end, and a resilient tongue extending along said transmission line, the proximal end of said tongue being fixed to said inner cylinder portion.
Claim 6
Dependent Claim
59 words
A connector device according to claim 1, 2, 3 or 4 wherein said movable housing includes an independent outer cylinder portion fitted loosely on the outer peripheral edge of said first flange portion of said stationary housing, said second flange portion and said outer cylinder portion of said movable housing being engagedly fixed to each other by engaging means.
Claim 7
Dependent Claim
56 words
A connector device according to claim 1, 2 or 3 wherein said movable housing includes an inner cylinder portion fixedly fitted with said other end of said transmission line, as an inner coil end, and a resilient tongue extending along the transmission line, the proximal end of said tongue being fixed to said inner cylinder portion.
Claim 8
Dependent Claim
59 words
A connector device according to claim 1, 2, 3 or 6 wherein said stationary housing includes an independent outer cylinder portion fitted loosely on the outer peripheral edge of said second flange portion of said movable housing, said first flange portion and said outer cylinder portion of said stationary housing being engagedly fixed to each other by engaging means.
Claim 9
Dependent Claim
131 words
A connector device according to any preceding claim wherein said second flange portion is formed, on the outer surface thereof, with a spiral groove whose number of turns is equivalent to the allowable number of revolutions of said movable housing, a sliding member fitted in said spiral groove, and a guide member having one end fixed to said stationary housing and the other end extending across said spiral groove, said sliding member being adapted to slide relatively on said spiral groove as said movable housing rotates, so that the number of revolutions of said movable housing is indicated by the position of said moved sliding member, said guide member restraining said sliding member from moving in the circumferential direction, and allowing said sliding member to move only in the radial direction.
Claim 10
Dependent Claim
17 words
A connector device according to any preceding claim wherein said transmission line is an electric wire cable.
Claim 11
Dependent Claim
27 words
A connector device according to claim 9, wherein said electric wire cable includes conductors connected directly to conductors of lead wires by pressure-coupling, using a pressure-coupling fitting.
Claim 12
Dependent Claim
21 words
A connector device according to any preceding claim wherein said transmission line is an optical transmission line threaded with optical fibers.
