Abstract
Abstract An apparatus useful in the assembly and testing of the multiconductor cable assemblies which in a first mode of operation indicates the path for each conductor and indicates the path for each succeeding conductor only after such conductor has been properly terminated. In a second mode of operation a completed cable assembly may be checked out to determine whether each of its conductors properly extends between its desired terminators. In a further mode of operation each conductor may be checked against the remaining conductors of the cable assembly in order to insure absence of shorts between such conductors and the remaining conductors of the cable. Various indicators are provided to indicate the particular conductor under test, to indicate whether or not termination has been properly made and if a short exists. Further, test procedures built into the apparatus prevent the device from further functioning where conditions exist either due to a misterminated conductor or by the presence of a short between a selected conductor and the remaining conductors of the cable.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
212 words
An apparatus for the identifying and testing of a plurality of conductors comprising: a plurality of pairs of terminator devices; one of said pairs of terminator devices for each conductor to be identified and tested and arranged to receive a conductor therebetween; a plurality of pairs of visual indicators, each of said pairs being disposed adjacent and coupled to an associated pair of said terminator devices; selector means coupled to said terminator devices and said indicators for sequentially selecting said terminator device pairs and sequentially energizing said associated visual indicator pairs to positionally identify the physical location of an associated terminator pair prior to the receipt of a conductor therebetween; sequencing means coupled to said selector means to sequence said selector in accordance with a predetermined sequence; testing means coupled to said selector means and said sequencing means; said testing means responding to signals from said selector means to produce a check signal when a conductor has been correctly placed between a selected associated pair of terminator devices to operate said sequencing means to cause said selection means to select a further pair of terminator devices; and remote position indicating means coupled to said selector means whereby the pair of terminator devices selected is indicated at a position remote from said pair.
Claim 2
Independent Claim
212 words
An apparatus for the identifying and testing of a plurality of conductors comprising: a plurality of pairs of terminator devices; one of said pairs of terminator devices for each conductor to be identified and tested and arranged to receive a conductor therebetween; a plurality of pairs of visual indicators, each of said pairs being disposed adjacent and coupled to an associated pair of said terminator devices; selector means coupled to said terminator devices and said indicators for sequentially selecting said terminator device pairs and sequentially energizing said associated visual indicator pairs to positionally identify the physical location of an associated terminator pair prior to the receipt of a conductor therebetween; sequencing means coupled to said selector means to sequence said selector in accordance with a predetermined sequence; testing means coupled to said selector means and said sequencing means; said testing means responding to signals from said selector means to produce a check signal when a conductor has been correctly placed between a selected associated pair of terminator devices to operate said sequencing means to cause said selection means to select a further pair of terminator devices; and remote position indicating means coupled to said selector means whereby the pair of terminator devices selected is indicated at a position remote from said pair.

An apparatus so defined in claim 1, further comprising: delay means coupled to said testing means and said sequencing means and responsive to said check signal from said testing means to operate said sequencing means after a predetermined delay.
Claim 4
Dependent Claim
35 words
An apparatus, as defined in claim 1, further comprising: a test indicator means coupled to said testing means and responsive to said check signal for producing an indication that said check signal has been produced.
Claim 5
Dependent Claim
35 words
An apparatus, as defined in claim 2, further comprising: a test indicator means coupled to said testing means and responsive to said check signal for producing an indication that said check signal has been produced.

An apparatus, as defined in claim 1, further comprising: mode selection means coupled to said testing means and said sequencing means; said mode selection means establishing the predetermined sequence of said sequencing means.
Claim 8
Dependent Claim
68 words
An apparatus, as defined in claim 4, further comprising: mode selection means coupled to testing means and said sequencing means; said mode selection means establishing the predetermined sequence of said sequencing means; said mode selection means when set in a first position permitting the operation of said delay means and said test indicator means and in a second position disabling said delay means and said test indicator means.
Claim 9
Dependent Claim
20 words
An apparatus, as defined in claim 7, wherein said mode selection means has a third position to reset said apparatus.
Claim 10
Dependent Claim
40 words
An apparatus, as defined in claim 1, further comprising: short checking means coupled to said selector means and said sequencing means; said short checking means checking said Selected associated pair of terminator devices against all remaining pairs of terminator devices.
Claim 11
Dependent Claim
66 words
An apparatus, as defined in claim 7, further comprising short checking means coupled to said selection means, said mode selection means and said sequencing means; said short checking means being enabled when said mode selection means is in a third position to check said selected associated pair of terminator devices against all remaining pairs of terminator devices and advance said sequencing means if no short exists.
Claim 12
Dependent Claim
18 words
An apparatus, as defined in claim 10, further comprising: short indication means coupled to said short checking means.
