Abstract
Abstract There is described an apparatus comprising a flat ribbon cable including a plurality of electrical conductors connected between two contact locations rotatable one with respect to the other. At each end of the flat ribbon cable, there is provided a connection line including a plurality of connection conductors, and a connection assembly comprised of a receptacle assembly and a plug assembly. The receptacle assembly surrounds an end portion of the flat ribbon cable including uninsulated portions of the electrical conductors, while the plug assembly includes a plurality of spring contacts each attached to an end of one of the connection conductors. Upon insertion of the plug assembly into the receptacle assembly, the spring contacts compressively engage mechcially fixed, uninsulated portions of the electrical conductors, thus providing electrical contacts therebetween.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
In an apparatus for providing an electrical conductive path between a first contact location and a second contact location rotatable one with respect to the other, said electrical conductive path comprising a flat ribbon cable wound in the manner of a coiled spring and comprising a plurality of electrical conductors; the improvement comprising an end portion of said flat ribbon cable being connected by way of a connection assembly to one end of a connection line having a plurality of connection conductors, said connection assembly comprising: a receptacle means comprised of insulating material and surrounding an end portion of said flat ribbon cable, said receptacle means including a fixed support means against which extend uninsulated portions of said electrical conductors; and plug means comprising a plurality of spring contacts each attached to an end of one of said plurality of connection conductors, said plug means being insertable into said receptacle means with said spring contacts compressively engaging said uninsulated portions of said electrical conductors.
Claim 2
Dependent Claim
164 words
In an apparatus for providing an electrical conductive path between a first contact location and a second contact location rotatable one with respect to the other, said electrical conductive path comprising a flat ribbon cable wound in the manner of a coiled spring and comprising a plurality of electrical conductors; the improvement comprising an end portion of said flat ribbon cable being connected by way of a connection assembly to one end of a connection line having a plurality of connection conductors, said connection assembly comprising: a receptacle means comprised of insulating material and surrounding an end portion of said flat ribbon cable, said receptacle means including a fixed support means against which extend uninsulated portions of said electrical conductors; and plug means comprising a plurality of spring contacts each attached to an end of one of said plurality of connection conductors, said plug means being insertable into said receptacle means with said spring contacts compressively engaging said uninsulated portions of said electrical conductors.
Claim 3
Dependent Claim
50 words
An apparatus in accordance with claim 1, wherein said receptacle means comprises a housing, and a first part and a second part each partially insertable into said housing, said first insertable part including said fixed support means and said second insertable part including an aperture for receiving said plug means.
Claim 4
Dependent Claim
37 words
An apparatus in accordance with claim 2, wherein said fixed support means comprises an elongated support portion of said first insertable part, said elongated support portion having said uninsulated portions of said electrical conductor extending longitudinally thereabout.
Claim 5
Dependent Claim
33 words
