Abstract

A plurality of precision cables simultaneously constructed on an assembly device having wire retainers arranged in a corresponding plurality of cable patterns. Each assembly step is successively performed on the plurality of substantially identical cable patterns before the next step is commenced to facilitate assembler efficiency. The precision electrical cables are assembled in a generally linear form with individual wire terminals intermediate their ends and with a selected amount of slack provided in at least some of the individual wires which is retained between cable bindings to permit subsequent bending of the cable between the bindings without substantial relative displacement of the individual wire terminals. The linear form facilitates both use of a tie gun for binding the wires of the cable together and compact mounting of a plurality of cable patterns on a single cable assembly apparatus.

Claims

1. A method of assembling an insulated wire cable of selected configuration, comprising the steps of:

(a) stringing a plurality of wires between a starting point and a finishing point for each wire along a path that is common for at least a portion of at least some of said wires, said common path being a substantially linear path;

(b) providing a selected amount of extra length in at least some of the individual wires from their starting points to their finishing points;

(c) binding the wires together at selected points along said common path;

(d) bending the bound wires into the selected configuration;

(e) binding said extra length between bindings on opposite sides of the bends; and

(f) greater amounts of extra length being selected for those wires located increasingly closer to the outside of the bends.

2. A method of assembling a plural number of insulated wire cables by repetitively applying each step of the method of claim 1 said plural number of times in succession until said plural number of cables have been assembled.

3. The method of claim 2 in which said plurality of wires comprise a plurality of selected groups of wires and each group of wires is repetitively strung said plural number of times before the next group of wires is strung.

4. A device for simultaneously assembling a plurality of insulated wire cables comprising:

(a) a board member;

(b) means defining a plurality of substantially identical cable paths disposed on said board member;

(c) pin-like retaining means mounted to said board member at intermittent widely spaced positions along said cable paths for securing individual wires of different lengths along each of said cable paths;

(d) each of said paths being a substantially linear path; and

(e) said paths being disposed in a vertical array and substantially parallel to each other whereby a cable assembler may manually grasp and secure wires to said cable paths proceeding from one cable path to another on the same board to produce sequentially a plurality of cable assemblies.

5. The device of claim 4 wherein each of said paths are substantially horizontal.

6. The device of claim 4 wherein said retaining means comprises a series of elongate members extending outwardly away from the frame located along each of the paths.

7. The device of claim 4 including means for designating various termination points for said individual wires for each of said plural paths.

8. The device of claim 7 wherein said designation means is a printed paper pattern containing terminal information for each of said plural paths.

9. The device of claim 4 in which there are at least three substantially identical paths thereon.
