Abstract
Abstract A machine for making and testing a cable harness assembly having planar, multi-conductor cable terminated to insulation displacement contacts housed in connectors. The machine includes a test module having a programmed microprocessing unit for executing the testing procedure. A series of manually operable switches are provided, the conditions of which are detectable by the computer. These switches are then set to indicate the number of contacts present in the connectors being terminated and to indicate which of these contact positions are to be tested. Additionally, the order of correspondence of the contacts of one connector to the other connector may be reversed by actuating a forward/reverse switch. The test module includes a learn mode, where a cable assembly of known configuration is placed into the machine. The test module then determines the continuity paths of the cable assembly and uses that information to test subsequently made cable assemblies.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
In a cable making machine for making a cable assembly including a cable having conductors terminated to contacts of a first connector at one end and contacts of a second connector at the other end, testing means for testing electrical continuity between said contacts of said first and second connectors of said cable assembly, some of said contacts of said first connector having a one to one correspondence with a contact of said second connector, comprising: (a) first and second sets of probes for making electrical contact with said contacts of said first and second connectors respectively; (b) continuity means for testing electrical continuity between said probes of said first set and their corresponding probes of said second set; and (c) control means for causing said continuity means to selectively effect said testing in either a selected predetermined order of correspondence or a learned order of correspondence.
Claim 2
Dependent Claim
147 words
In a cable making machine for making a cable assembly including a cable having conductors terminated to contacts of a first connector at one end and contacts of a second connector at the other end, testing means for testing electrical continuity between said contacts of said first and second connectors of said cable assembly, some of said contacts of said first connector having a one to one correspondence with a contact of said second connector, comprising: (a) first and second sets of probes for making electrical contact with said contacts of said first and second connectors respectively; (b) continuity means for testing electrical continuity between said probes of said first set and their corresponding probes of said second set; and (c) control means for causing said continuity means to selectively effect said testing in either a selected predetermined order of correspondence or a learned order of correspondence.
Claim 3
Dependent Claim
33 words
The testing means according to claim 1 including means for selecting some but not all of said probes and wherein said probes tested by said means for testing are only said selected probes.
Claim 4
Dependent Claim
44 words
The testing means according to claim 2 wherein said predetermined order of correspondence is defined by the 1st, 2nd, . . . , nth probes of said first set corresponding to the 1st, 2nd, . . . , nth probes of said second set.
Claim 5
Dependent Claim
44 words
The testing means according to claim 2 wherein said predetermined order of correspondence is defined by the 1st, 2nd, . . . , nth probes of said first set corresponding to the nth, (n-1)th, . . . , 1st probes of said second set.
Claim 6
Dependent Claim
19 words
