Abstract An apparatus is described for providing an electrical conduction path between two contact locations rotatable one with respect to the other. A flat ribbon cable having a plurality of electrical conductors and being wound in the manner of a coiled spring, is connected to the contact locations by way of connection lines serially connected to the ends of the flat ribbon cable. To protect the flat ribbon cable from mechanical damage at each of its ends, an end portion of each of the electrical conductors is serially connected to an end portion of one of a plurality of connection conductors of the connection line at a connection location, and a connection assembly is formed about the end portions of the serially connected conductors. The connection assembly is comprised of a clamping body positioned about and engaging a portion of each of the connection conductors so as to restrict axial movement therebetween; and a protective sheath that encompasses the connection locations of each of the serially connected conductors, while engaging the clamping body to restrict axial movement therebetween.
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 having a plurality of electrical conductors and being wound in the manner of a coiled spring; the improvement comprising each of said electrical conductors having an uninsulated end portion thereof serially connected at a connection location to one of a plurality of connection conductors at an uninsulated end portion thereof; and a connection assembly comprising: a clamping body of insulating material positioned about and engaging a segment of each of said uninsulated end portions of each of said connection conductors, said engagement being removed from said connection location of each of said serially connected conductors, said clamping body comprising a pair of clamping segments closable one against the other, one of said clamping segments including protrusion means about which each of said uninsulated end portions of said connection conductors axially bend at least twice so as to restrict axial movement thereof; and a protective sheath of insulating material axially positioned about said connection location of each of said serially connected conductors, and axially positioned about and engaging said clamping body so as to restrict axial movement therebetween.
