Abstract
Abstract An automatic testing device for a multiconductor electric cable two ends of which are respectively connected to two connectors, where conductors of the multiconductor electric cable are divided into a plurality of groups of series-connected conductors by connecting respectively two connection adapters to said two connectors. Respective paired terminals of the groups of seriesconnected conductors are connected to a plurality of testing means successively testing in an automatic manner whether or not each of the series-connected conductors forms a complete series connection. The test results of the testing means are displayed by display means.

Claim 1
Independent Claim
356 words
An automatic testing device for a multiconductor electric cable two ends of which are respectively connected to two connectors, comprising: a first connection adapted coupled to one of the two connectors and having the same number of terminals as the number of connectors of the multiconductor electric cable, the terminals of this first connection adapter being paired off so as to form a plurality of series-connected pairs of terminals; a second connection adapter coupled to the other of the connectors and having the same number of terminals as the number of conductors of the multiconductor electric cable, the terminals of this second connection adapter being paired off except some of the terminals the number of which is equal to twice a desired number of groups so that the conductors of the multiconductor electric cable are divided into said desired number of groups of series-connected conductors, the paired terminals of said series-connected conductors corresponding to respective pairs of said some of the terminals of the second connection adapter, a plurality of testing means respectively connected to said terminals of the groups of series-connected conductors to assume each an ON-state if corresponding one of the groups of the series-connected conductors foRms a complete series connection; a first control means coupled with a first one of the testing means testing the fist group of the series-connected conductors to start at first said first one of the testing means; a plurality of self-hold means coupled respectively to the testing means to self-hold said ON-state thereof; a plurality of second control means each coupled with corresponding one of the testing means to energize the just succeeding one of the testing means in response to said ONstate of the corresponding one of the testing means; a plurality of release means each coupled to successive two of the testing means to release the ON-state of the preceding one of said successive two of the testing means in response to the ON-state of the succeeding one of the successive two of the testing means; and display means coupled to a plurality of said testing means to display the test results of the testing means.

An automatic testing device for a multiconductor electric cable two ends of which are respectively connected to two connectors, comprising: a first connection adapted coupled to one of the two connectors and having the same number of terminals as the number of connectors of the multiconductor electric cable, the terminals of this first connection adapter being paired off so as to form a plurality of series-connected pairs of terminals; a second connection adapter coupled to the other of the connectors and having the same number of terminals as the number of conductors of the multiconductor electric cable, the terminals of this second connection adapter being paired off except some of the terminals the number of which is equal to twice a desired number of groups so that the conductors of the multiconductor electric cable are divided into said desired number of groups of series-connected conductors, the paired terminals of said series-connected conductors corresponding to respective pairs of said some of the terminals of the second connection adapter, a plurality of testing means respectively connected to said terminals of the groups of series-connected conductors to assume each an ON-state if corresponding one of the groups of the series-connected conductors foRms a complete series connection; a first control means coupled with a first one of the testing means testing the fist group of the series-connected conductors to start at first said first one of the testing means; a plurality of self-hold means coupled respectively to the testing means to self-hold said ON-state thereof; a plurality of second control means each coupled with corresponding one of the testing means to energize the just succeeding one of the testing means in response to said ONstate of the corresponding one of the testing means; a plurality of release means each coupled to successive two of the testing means to release the ON-state of the preceding one of said successive two of the testing means in response to the ON-state of the succeeding one of the successive two of the testing means; and display means coupled to a plurality of said testing means to display the test results of the testing means.
Claim 3
Dependent Claim
73 words
An automatic testing device according to claim 1, in which the first control means is directly coupled to the first one of the testing means testing the first group of the series-connected conductors, so that the first one of the testing means assumes at once the ON-state in response to power supply to the testing means if the series-connected conductors connected to the first one of the testing means forms a complete series-connection.
Claim 4
Dependent Claim
74 words
An automatic testing device according to claim 1, in which the first control means is indirectly coupled to the first one of the testing means testing the first group of the series-connected conductors, so that the first one of the testing means assumes the ON-state after a delay time from power supply to the testing means if the series-connected conductors connected to the first one of the testing means forms a complete series connection.
Claim 5
Dependent Claim
36 words
An automatic testing device according to claim 1, including means for dividing the groups of the series-connected conductors into two sets of groups, and means for testing an insulation resistance between said two sets of groups.
