Abstract
Abstract In connecting flat multiconductor cables, one cable is placed atop another to provide a matrix of zones in which connections may be made of any conductor of one cable to any conductor of the other cable. Selection is made of one zone and it is perforated. An insulating-piercing connector is inserted through the perforation and crimped to provide an electrical connection between the pair of cable conductors in registry with the selected zone. Selection of further zones for perforation and connector insertion is made progressively from those zones which do not have in registry therewith any conductor which was in registry with any previously selected zone. Apparatus for implementing preferred connection zone selection precludes use of connecting zones other than a singular zone for connection of one conductor pair and compels use of a selective few zones individually for connection of respective other conductor pairs, thereby lessening connection error likelihood.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A method for interconnection of flat multiconductor cables, comprising the steps of: (a) placing one such cable in overlying relation to another such cable in manner providing a matrix of connection zones wherein each zone has a unique pair of cable conductors in registry therewith; (b) selecting an origin connection zone having in registry therewith first conductors of said cables and precluding from connection use all other zones in registry with said first conductors; (c) perforating said first conductors at said origin zone and making electrical connection therebetween; (d) providing for selection plural zones in registry with a second conductor of one of said cables and precluding from connection use all other zones in registry with said second conductor; (e) selecting further zones for perforation and connection of conductors until connections are made to all conductors of at least one of said cables, each such further zone being selected from the group of zones which do not have in registry therewith any conductor in registry with any previously selected zone.
Claim 2
Independent Claim
170 words
A method for interconnection of flat multiconductor cables, comprising the steps of: (a) placing one such cable in overlying relation to another such cable in manner providing a matrix of connection zones wherein each zone has a unique pair of cable conductors in registry therewith; (b) selecting an origin connection zone having in registry therewith first conductors of said cables and precluding from connection use all other zones in registry with said first conductors; (c) perforating said first conductors at said origin zone and making electrical connection therebetween; (d) providing for selection plural zones in registry with a second conductor of one of said cables and precluding from connection use all other zones in registry with said second conductor; (e) selecting further zones for perforation and connection of conductors until connections are made to all conductors of at least one of said cables, each such further zone being selected from the group of zones which do not have in registry therewith any conductor in registry with any previously selected zone.
Claim 3
Dependent Claim
59 words
The method claimed in claim 1 wherein said step (e) is practiced by selecting for connection a zone adjacent said origin zone and having in registry therewith third conductors of said cables and precluding from connection use all other zones in registry with said third conductors, perforating said third conductors at such adjacent zone and making electrical connection therebetween.
Claim 4
Dependent Claim
24 words
The method claimed in claim 1 wherein said step (a) is further practiced by disposing said first and second cables in mutually orthogonal relation.
Claim 5
Dependent Claim
28 words
The method claimed in claim 1 wherein said steps (b) and (c) are practiced by conforming such selection therein to a pattern having predetermined geometry in said matrix.
Claim 6
Dependent Claim
47 words
The method claimed in claim 1 wherein said step (a) is further practiced by disposing said first and second cables in mutually orthogonal relation and wherein said steps (b) and (c) are practiced by conforming such selection therein to a pattern having predetermined geometry in said matrix.
Claim 7
Dependent Claim
32 words
The method claimed in claim 5 wherein said predetermined geometry comprises a diagonal of said matrix and wherein first, second and third of said selected connection locations are disposed along said diagonal.
