Abstract
Abstract An apparatus is disclosed for automatically making and testing electrical cable assemblies. A novel coupling is provided between the bulk cable contained on a large reel and the logic circuitry of the automated machine so that individual wires within the cable can be identified, inserted into a desired terminal of a connector, and tested. The coupling utilizes a slip ring assembly to communicate with the individual wires of the cable through a connector that has been previously terminated on a pigtail extending from the central core of the reel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
220 words
In a machine for automatically identifying and terminating wires of a multi-wire cable to corresponding terminals of a connector, said machine including: (1) a length of multi-wire cable wound about a reel, arranged for rotation with respect to said machine, said cable having a first end proximate the rotational axis of said reel and a second end extending from the periphery of said reel; (2) a frame having an axle for receiving any one of a plurality of different cable reels for rotation thereon; (3) apparatus for accepting said second end and applying a signal to a selected wire of said cable; (4) control means for monitoring a plurality of electrodes, which are non-rotationally coupled to said machine, identifying a specific one of said electrodes having said signal impressed thereon, and determining a desired terminal of said connector that corresponds to said selected wire; the improvement comprising: means for releasably connecting the wires of said first end of said cable with corresponding ones of said plurality of electrodes while permitting rotation of said reel comprising: (a) a first connector having terminals which are terminated to the wires of said first end of said cable; and (b) rotational coupling means attached to said frame for electrically coupling said terminals of said first connector with corresponding electrodes of said plurality of electrodes.
Claim 2
Dependent Claim
220 words
In a machine for automatically identifying and terminating wires of a multi-wire cable to corresponding terminals of a connector, said machine including: (1) a length of multi-wire cable wound about a reel, arranged for rotation with respect to said machine, said cable having a first end proximate the rotational axis of said reel and a second end extending from the periphery of said reel; (2) a frame having an axle for receiving any one of a plurality of different cable reels for rotation thereon; (3) apparatus for accepting said second end and applying a signal to a selected wire of said cable; (4) control means for monitoring a plurality of electrodes, which are non-rotationally coupled to said machine, identifying a specific one of said electrodes having said signal impressed thereon, and determining a desired terminal of said connector that corresponds to said selected wire; the improvement comprising: means for releasably connecting the wires of said first end of said cable with corresponding ones of said plurality of electrodes while permitting rotation of said reel comprising: (a) a first connector having terminals which are terminated to the wires of said first end of said cable; and (b) rotational coupling means attached to said frame for electrically coupling said terminals of said first connector with corresponding electrodes of said plurality of electrodes.
Claim 3
Dependent Claim
