Cable harness manufacturing and electrical testing system

Claim 1

A method for the simultaneous manufacturing and electrical testing of a cable harness assembly having a harness length and at least a first connector, of the insulation displacement type, terminated to a planar multi-conductor cable, comprising the steps of a. feeding said cable past a cable shearing station and through said first connector, b. terminating said first connector to said cable, c. testing said first connector and cable to verify an appropriately terminated connector, d. if an additional connector is needed proceed to step e, otherwise: (1) advance said first connector and cable a distance downstream from said shearing station equivalent to said harness length, (2) shear said cable at said shearing station while simultaneously testing the sheared cable to verify continuity between said first connector and the cable end resulting from the shearing thereof, (3) eject said cable harness assembly; e. if more than one additional connector is needed proceed to step f, otherwise: (1) advance said first connector and cable a distance downstream from said shearing station equivalent to said harness length, (2) shear said cable, (3) terminate a last connector to said cable, (4) test said last connector and cable to verify an appropriately terminated connector (5) eject said cable harness assembly; f. advance said first connector and cable a predetermined distance downstream from said shearing station, g. terminated an additional connector to said cable, h. test said additional connector and cable to verify an appropriately terminated connector, i. proceed to step e; wherein after each said testing step, if the test fails to verify an appropriately terminated connector or continuity throughout the cable, said cable shearing station is immediately activated to cut said cable in the event the cable has not previously been cut, whereafter the cut failed cable harness portion is discarded.

Claim 2

A method for the simultaneous manufacturing and electrical testing of a cable harness assembly having a harness length and at least a first connector, of the insulation displacement type, terminated to a planar multi-conductor cable, comprising the steps of a. feeding said cable past a cable shearing station and through said first connector, b. terminating said first connector to said cable, c. testing said first connector and cable to verify an appropriately terminated connector, d. if an additional connector is needed proceed to step e, otherwise: (1) advance said first connector and cable a distance downstream from said shearing station equivalent to said harness length, (2) shear said cable at said shearing station while simultaneously testing the sheared cable to verify continuity between said first connector and the cable end resulting from the shearing thereof, (3) eject said cable harness assembly; e. if more than one additional connector is needed proceed to step f, otherwise: (1) advance said first connector and cable a distance downstream from said shearing station equivalent to said harness length, (2) shear said cable, (3) terminate a last connector to said cable, (4) test said last connector and cable to verify an appropriately terminated connector (5) eject said cable harness assembly; f. advance said first connector and cable a predetermined distance downstream from said shearing station, g. terminated an additional connector to said cable, h. test said additional connector and cable to verify an appropriately terminated connector, i. proceed to step e; wherein after each said testing step, if the test fails to verify an appropriately terminated connector or continuity throughout the cable, said cable shearing station is immediately activated to cut said cable in the event the cable has not previously been cut, whereafter the cut failed cable harness portion is discarded.

Claim 6

A method for the simultaneous manufacturing and electrical testing of a cable harness assembly having a leading connector, a trailing connector, and optionally one or more intermediate connectors of the insulation displacement type spaced along a planar multi-conductor cable, comprising the steps of a. feeding said cable past a cable shearing station and sequentially through said trailing connector, optionally one or more of said intermediate connectors, and said leading connector, b. terminating said leading connector to said cable, c. testing said leading connector and cable to verify an appropriately terminated connector, d. advancing said leading connector and cable a predetermined distance downstream from said shearing station, e. terminating an intermediate connector when present, to said cable, f. testing said intermediate connector, when present, and cable to verify an appropriately terminated connector and continuity between terminated connectors, g. repeating steps (d) through (f) for each additional intermediate connector of step (a), h. advancing said leading and present intermediate connectors and cable downstream to a position defining the length of said cable harness assembly, i. shearing said cable at said shearing station, j. terminating said trailing connector to said cable, and k. testing said trailing connector and cable to verify an appropriately terminated connector and continuity between terminated connectors, wherein, after each said testing step, if the test fails to verify an appropriately terminated connector or continuity between terminated connectors, said cable shearing station is immediately activated to cut said cable, whereafter the cut failed cable harness portion is discarded.

Claim 7

A method for the simultaneous manufacturing and electrical testing of a cable harness assembly having a leading connector, a trailing connector, and optionally one or more intermediate connectors of the insulation displacement type spaced along a planar multi-conductor cable, comprising the steps of a. feeding said cable past a cable shearing station and sequentially through said trailing connector, optionally one or more of said intermediate connectors, and said leading connector, b. terminating said leading connector to said cable, c. testing said leading connector and cable to verify an appropriately terminated connector, d. advancing said leading connector and cable a predetermined distance downstream from said shearing station, e. terminating an intermediate connector when present, to said cable, f. testing said intermediate connector, when present, and cable to verify an appropriately terminated connector and continuity between terminated connectors, g. repeating steps (d) through (f) for each additional intermediate connector of step (a), h. advancing said leading and present intermediate connectors and cable downstream to a position defining the length of said cable harness assembly, i. shearing said cable at said shearing station, j. terminating said trailing connector to said cable, and k. testing said trailing connector and cable to verify an appropriately terminated connector and continuity between terminated connectors, wherein, after each said testing step, if the test fails to verify an appropriately terminated connector or continuity between terminated connectors, said cable shearing station is immediately activated to cut said cable, whereafter the cut failed cable harness portion is discarded.
