Abstract
Abstract Apparatus and method for fabricating a multi-wire harness assembly are disclosed. The harness consists of wires which are first terminated en masse on one level, then loaded en masse into a connector block on a conveyor at a lower level. Wires are then fed to diverse lengths, cut and stripped, and the trailing ends are transported on a conveyorized clamp which parallels the connector block clamp. The apparatus utilizes a shuttle having telescoping wire guide tubes which are directed by a pivotable track first to an operating zone for termination. The shuttle has a clamping mechanism so that the terminated leads are drawn into the expanding tubes as the shuttle retreats. The track then pivots to the level of the connector, the shuttle moves against the connector block to load the terminated leads, and the clamp is released as the shuttle retreats from the block over the wires. A comb-like deflector with arcuate channels moves onto the wires and a remote axial wire feeder pays out the wire through the shuttle to loops of various lengths between the loaded connector block and the deflector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
226 words
In the method of manufacture of electrical harnesses of the type comprising an insulating connector block having a plurality of contact terminals therein, said terminals being arranged in side-by-side relationship in a row, wires having their ends connected to said terminals, said method comprising the step of feeding each of said wires from an endless source of wire toward said connector block by means of feed roll means, the wires being fed along a wire feed path in side-by-side coplanar relationship toward said connector, said method being characterized in that: after said wires are connected to said terminals in said connector block and said connector is positioned at a predetermined location in said feed path which is downstream, relative to the direction of wire feed, from said feed rolls, wire deflector means is positioned on said feed path between said connector and said feed roll means, said deflector means having deflecting surface portions which bear against respective wires, said feed roll means is thereafter actuated to feed lengths of wire from said wire sources axially against said deflecting surface portions to form loops in said wires transversely of the plane of said feed path between said deflector means and said connector block, said deflector means remaining stationary during wire feed, said wires are thereafter cut at a location between said deflector and said feed roll means.
Claim 2
Dependent Claim
226 words
In the method of manufacture of electrical harnesses of the type comprising an insulating connector block having a plurality of contact terminals therein, said terminals being arranged in side-by-side relationship in a row, wires having their ends connected to said terminals, said method comprising the step of feeding each of said wires from an endless source of wire toward said connector block by means of feed roll means, the wires being fed along a wire feed path in side-by-side coplanar relationship toward said connector, said method being characterized in that: after said wires are connected to said terminals in said connector block and said connector is positioned at a predetermined location in said feed path which is downstream, relative to the direction of wire feed, from said feed rolls, wire deflector means is positioned on said feed path between said connector and said feed roll means, said deflector means having deflecting surface portions which bear against respective wires, said feed roll means is thereafter actuated to feed lengths of wire from said wire sources axially against said deflecting surface portions to form loops in said wires transversely of the plane of said feed path between said deflector means and said connector block, said deflector means remaining stationary during wire feed, said wires are thereafter cut at a location between said deflector and said feed roll means.
Claim 3
Dependent Claim
35 words
The method of manufacture of electrical harnesses of claim 1 wherein said feed roll means comprises an individual set of feed roll means for each wire, whereby said wires may be fed to varying lengths.
Claim 4
Dependent Claim
49 words
The method of manufacture of electrical harnesses of claim 1 wherein said wire deflector means comprises a comb-type deflector having teeth spaced to pass between said wires in said side-by-side coplanar relationship, said teeth defining spaces therebetween which are contiguous with arcuate channels which define said deflecting surface portions.
Claim 5
Dependent Claim
38 words
The method of manufacture of electrical harnesses of claim 1 wherein said connector block remains stationary after said wires are connected to said terminals in said block and prior to positioning said deflector means on said feed path.
