Abstract
Abstract A test assembly for testing a preassembled wiring harness for location of mounting brackets at spaced points on the harness assembly and for evaluating terminals of the wiring harness includes a faceplate with a plurality of slots formed across the full planar extent thereof to accommodate a variety of different holder and detecting device layouts corresponding to a variety of types of wiring harness configurations. A separate faceplate is supported on each of a plurality of modular units joined together to accept different length wiring harness configurations. Standard length cables are connected to each of the holders and detecting devices. The cables have a connector wired thereto which fits through the slots to provide access from the faceplate to the interface cards without splicing into the wiring system. The modular frame units include a standardized mounting arrangement for interface boards or cards that include circuit components for simulating different modes of wiring harness use to be evaluated by a wiring harness tester control. The modular frame system includes a support platform thereon configured to releasably secure the harness tester in a fixed location with respect to the interface board components.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
246 words
In a test assembly for checking the operative characteristics, presence of harness mounting features and electrical terminals for coupling a preassembled wiring harness in operative position in an environment by use of interface circuit boards and a harness tester for selectively connecting individual ones of the circuit boards to the preassembled wiring harness in accordance with a desired testing sequence the improvement comprising: a plurality of modular units including frame means adapted to be jointed end to end to accommodate different length preassembled wiring harnesses of varying form, fit and function; each of said modular units including a faceplate with an inner and outer surface and having slot means therein extending across the full planar extent of the outer surface thereof; a plurality of standardized brackets; said slot means comprising a plurality of elongated slots which are formed in ranks which alternately overlap to provide openings for mounting and locating said standardized brackets in a spaced array corresponding to the form, fit and function of a preassembled wiring harness; fastener means cooperating with said slot means for adjustably securing said brackets with respect to each of said faceplates so as to permit spatial adjustment thereof with respect to a preselected preassembled wiring harness; and coupling means on said brackets for providing either an electrical connection to a wiring harness or for detecting the presence of mounting means thereon when the wiring harness is in a desired attitude corresponding to the assembled position of the wiring harness.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
71 words
In the test assembly of claim 1, an interface board, a standard length cable for each of said coupling means having opposite ends, one end of each said cable being prewired to one of said coupling means, and connector plug means on the opposite end of each said cable insertable through said slot means for electrically connecting said one coupling means to said interface board from any point on said faceplate.
Claim 4
Dependent Claim
89 words
In the test assembly of claim 1, said modular units each having a frame means with top, bottom and side brackets defining open ends, an inclined front opening and a rear opening; said faceplate covering said inclined front opening and means for hinging said faceplate to said frame means to provide access to the interior of said frame means from in front of said frame means and for providing access to said fastener means for tightening said brackets on said faceplate following adjustment thereof with respect to said faceplate.
Claim 5
Dependent Claim
39 words
In the test assembly of claim 3, means inside said frame means for fixedly supporting interface boards with respect to said frame means for electrical connection by standard length cable to both said coupling means and a harness tester.
Claim 6
Dependent Claim
40 words
In the test assembly of claim 3, the plurality of modular units including modular units at each end which have frame means defining open ends at their respective outboard ends and interchangeable end plates for covering the outboard open ends.
Claim 7
Dependent Claim
55 words
In the test assembly of claim 3, an interface board located interiorly of said frame means, said coupling means including prewired housings and a connector plug means passed through one of said slot means when said brackets are secured to said faceplate to extend inboard thereof to a point of connection on said interface board.
Claim 8
Dependent Claim
47 words
In the test assembly of claim 6, a harness tester located exteriorly of said frame means, said frame means having a standardized fixed location interiorly thereof for mounting said interface boards for connection by said connector plug means to both said coupling means and said harness tester.
Claim 9
Dependent Claim
24 words
In the test assembly of claim 1, means providing parallel electrical connections between the interface boards, said coupling means and the harness tester unit.
Claim 10
Dependent Claim
24 words
In the test assembly of claim 2, means providing parallel electrical connections between the interface boards, said coupling means and the harness tester unit.
