Abstract
Abstract An assembly apparatus is disclosed for manufacturing cable harnesses having a measured length of a multi-conductor flat flexible cable terminated by at least two electrical connectors. The assembly apparatus includes a conductor testing and cable cutting station, a connector crimp termination station, and a test fixture which electrically tests each connector for shorts and opens simultaneously with the crimping of the connector onto the cable.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
A cable harness assembly apparatus for terminating multi-conductor flat flexible cable with at least two connectors, each connector having a plurality of contact terminals fixed therein, while simultaneously testing the continuity of each connection, said apparatus comprising: a connector crimp terminating station having cable guide means, connector guide means, and press means to effect crimp engagement of contact terminals of said connector with respective conductors of said cable; and test indicating means having a test fixture engaged with the first terminated conductor and means to test electrical continuity of each connection as it is effected, said test indicating means comprising: counter means; multiplexer means and demultiplexer means connected in parallel to said counter means and said test fixture; first comparator means connected to receive outputs of said counter means, said multiplexer means and said demultiplexer means; display means connected to the output of said first comparator means; second comparator means connected to the output of said counter means and input of said first comparator means; and means to set the number of tests to be conducted to equal the number of conductors to be terminated.
Claim 2
Dependent Claim
185 words
A cable harness assembly apparatus for terminating multi-conductor flat flexible cable with at least two connectors, each connector having a plurality of contact terminals fixed therein, while simultaneously testing the continuity of each connection, said apparatus comprising: a connector crimp terminating station having cable guide means, connector guide means, and press means to effect crimp engagement of contact terminals of said connector with respective conductors of said cable; and test indicating means having a test fixture engaged with the first terminated conductor and means to test electrical continuity of each connection as it is effected, said test indicating means comprising: counter means; multiplexer means and demultiplexer means connected in parallel to said counter means and said test fixture; first comparator means connected to receive outputs of said counter means, said multiplexer means and said demultiplexer means; display means connected to the output of said first comparator means; second comparator means connected to the output of said counter means and input of said first comparator means; and means to set the number of tests to be conducted to equal the number of conductors to be terminated.
Claim 3
Dependent Claim
38 words
A cable harness assembly apparatus according to claim 1 further comprising: a cable cutting station having means to support a supply of multi-conductor flat flexible cable and means to cut measured lengths of said cable from said supply.
Claim 4
Dependent Claim
100 words
A cable harness assembly apparatus according to claim 2 wherein said means to cut measured lengths of cable comprises: a pair of parallel, spaced cutting blades; a comb-like member fixed between said blades and having a plurality of sharp pin contacts extending beyond the cutting edges of said cutting blades; and electrical test means connected to each said pin contact, whereby the insulation of said cable is pierced by said pin contacts to determine the correct positioning of the conductors carried thereby prior to cutting said cable, said parallel blades separating the tested segment from the rest of the cable.
Claim 5
Dependent Claim
71 words
A cable harness assembly apparatus according to claim 1 wherein said connector crimp terminating station comprises: crimp press means; guide means extending transversely beneath said press means; and a plurality of connector carrier fixtures slidably mounted on said guide means, whereby connectors are loaded into respective carrier fixtures and the loaded fixtures sequenced beneath the press means with the cable to effect a crimp termination of the connector onto the cable.
Claim 6
Dependent Claim
30 words
A cable harness assembly apparatus according to claim 4 wherein said carrier fixtures receive said connectors in a contact up condition and further include means to grippingly engage said cable.
Claim 7
Dependent Claim
51 words
A cable harness assembly apparatus according to claim 1 wherein said connector crimp terminating station comprises: crimp press means; guide means extending frontally beneath said press means and including means to clampingly position the cable; and means to support said connectors in a contact down condition for crimping onto said cable.
Claim 8
Dependent Claim
77 words
A cable harness assembly apparatus according to claim 1 wherein said test fixture comprises: a housing having a connector receiving face; a plurality of apertures in said face; an electrical contact lying within each said aperture and connected to test means; whereby the first crimped terminal is placed in said fixture with the connector contacts extending into said apertures to engage the contacts therein to effect electrical testing of continuity between the connector contacts and cable conductors.
Claim 9
Dependent Claim
19 words
A cable harness assembly apparatus according to claim 7 wherein said test fixture further comprises: cable strain relief means.
Claim 10
Dependent Claim
26 words
A cable harness assembly apparatus according to claim 1 wherein said display means comprises: a series of lights respectively indicating the tests conducted and results thereof.
Claim 11
Dependent Claim
26 words
A cable harness assembly apparatus according to claim 9 wherein said display means further comprises: digital readout means indicating the location of faults found by testing.
