Abstract
Abstract There is disclosed a connector device installed on an automotive steering wheel. The device comprises a stationary body, a movable body capable of rotating relative to the stationary body, and two belt-like flat cables stacked on each other. The cables are mounted in the space formed between the stationary body and the movable body. Each cable is wound with a given turns, and comprises two base sheet of film bonded together. Several straight conductors are juxtaposed and sandwiched between the base sheets.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
130 words
A connector device comprising: a stationary body; a movable body capable of rotating relative to the stationary body; and a plurality of belt-like flat cables stacked on each other and mounted in the space formed between the stationary body and the movable body, each of the cables being wound with a given number of turns, each of the cables including a plurality of identical conductors juxtaposed on a base sheet of film, the stationary body being electrically connected with the movable body via the conductors; wherein the conductors of a first cable of the plurality of cables are made from a material which differs in capacity of electric current per unit area from a material of which the conductors of a second cable of the plurality of cables are made.
Claim 2
Dependent Claim
130 words
A connector device comprising: a stationary body; a movable body capable of rotating relative to the stationary body; and a plurality of belt-like flat cables stacked on each other and mounted in the space formed between the stationary body and the movable body, each of the cables being wound with a given number of turns, each of the cables including a plurality of identical conductors juxtaposed on a base sheet of film, the stationary body being electrically connected with the movable body via the conductors; wherein the conductors of a first cable of the plurality of cables are made from a material which differs in capacity of electric current per unit area from a material of which the conductors of a second cable of the plurality of cables are made.
Claim 3
Dependent Claim
48 words
A connector device as set forth in claim 1, wherein reinforcing plates made from a material having a modulus of elasticity larger than that of the base sheet of film are embedded in the base sheet so as to extend along the longitudinal ends of the base sheet.
