Abstract
Abstract An electrical ribbon cable having a plurality of conductors positioned substantially within the same plane is mounted within a connector housing to a plurality of connecting terminals by contact screws having pointed ends for puncturing the insulation surrounding the ribbon cable to contact respective ones of the conductors. The flat surfaces of the ribbon cable include at least one longitudinal groove and a recess is formed in the connector housing conforming to the cross section of the ribbon cable and has at least one projection engaging with the longitudinal groove on the ribbon cable to predetermine the alignment of the conductors with the connecting terminals. The connector housing is provided with an insulating support forming the recess and a removable cover; the insulating support includes rib members and the cover has recesses aligned with the rib members so that the cover is mounted in only one predetermined position. The cover has passages through which external conductors are attached to the respective connecting terminals.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
166 words
An electrical ribbon cable and connector assembly comprising: a plurality of individually insulated parallel conductors positioned substantially within the same plane of an electrical ribbon cable, said ribbon cable having an outer insulating body including two opposite flat surfaces, at least one of said flat surfaces being provided with at least one asymmetrically disposed longitudinal groove; a connector housing; a plurality of connecting terminals corresponding to the plurality of said conductors mounted within said connector housing; a contact screw for each of said connecting terminals having a point for puncturing the insulation of said ribbon cable to contact a respective one of said conductors; a recess formed in said connector housing conforming to the cross section of said ribbon cable, said recess including at least one projection for engaging with said at least one longitudinal groove; whereby the alignment of said contact screws with said plurality of conductors is determined by the engagement of said at least one projection with said at least one longitudinal groove.
Claim 2
Dependent Claim
166 words
An electrical ribbon cable and connector assembly comprising: a plurality of individually insulated parallel conductors positioned substantially within the same plane of an electrical ribbon cable, said ribbon cable having an outer insulating body including two opposite flat surfaces, at least one of said flat surfaces being provided with at least one asymmetrically disposed longitudinal groove; a connector housing; a plurality of connecting terminals corresponding to the plurality of said conductors mounted within said connector housing; a contact screw for each of said connecting terminals having a point for puncturing the insulation of said ribbon cable to contact a respective one of said conductors; a recess formed in said connector housing conforming to the cross section of said ribbon cable, said recess including at least one projection for engaging with said at least one longitudinal groove; whereby the alignment of said contact screws with said plurality of conductors is determined by the engagement of said at least one projection with said at least one longitudinal groove.
Claim 3
Dependent Claim
166 words
An electrical ribbon cable and connector assembly comprising: a plurality of individually insulated parallel conductors positioned substantially within the same plane of an electrical ribbon cable, said ribbon cable having an outer insulating body including two opposite flat surfaces, at least one of said flat surfaces being provided with at least one asymmetrically disposed longitudinal groove; a connector housing; a plurality of connecting terminals corresponding to the plurality of said conductors mounted within said connector housing; a contact screw for each of said connecting terminals having a point for puncturing the insulation of said ribbon cable to contact a respective one of said conductors; a recess formed in said connector housing conforming to the cross section of said ribbon cable, said recess including at least one projection for engaging with said at least one longitudinal groove; whereby the alignment of said contact screws with said plurality of conductors is determined by the engagement of said at least one projection with said at least one longitudinal groove.
Claim 4
Dependent Claim
166 words
An electrical ribbon cable and connector assembly comprising: a plurality of individually insulated parallel conductors positioned substantially within the same plane of an electrical ribbon cable, said ribbon cable having an outer insulating body including two opposite flat surfaces, at least one of said flat surfaces being provided with at least one asymmetrically disposed longitudinal groove; a connector housing; a plurality of connecting terminals corresponding to the plurality of said conductors mounted within said connector housing; a contact screw for each of said connecting terminals having a point for puncturing the insulation of said ribbon cable to contact a respective one of said conductors; a recess formed in said connector housing conforming to the cross section of said ribbon cable, said recess including at least one projection for engaging with said at least one longitudinal groove; whereby the alignment of said contact screws with said plurality of conductors is determined by the engagement of said at least one projection with said at least one longitudinal groove.
Claim 5
Dependent Claim
49 words
An electrical ribbon cable and connector assembly as in claim 1 wherein both flat surfaces of said ribbon cable include at least one asymmetrically disposed longitudinal groove; said recess includes at least one pair of proJections for engagement with said longitudinal grooves on each side of the ribbon cable.
Claim 6
Dependent Claim
45 words
An electrical ribbon cable and connector assembly as in claim 2 wherein one edge side of said ribbon cable is flat and the other edge side is curved and the edges of said recess opposing said one edge side and said other have conforming shapes.
Claim 7
Dependent Claim
38 words
An electrical ribbon cable and connector assembly as in claim 3 wherein said ribbon cable includes three conductors for connection to the respective phase conductors of a three phase system and a neutral conductor and a grounding conductor.
Claim 8
Dependent Claim
34 words
An electrical ribbon cable and connector assembly as in claim 4 wherein said three conductors, and said neutral and grounding conductors respectively are located on opposite sides of said pair of opposed longitudinal grooves.
Claim 9
Dependent Claim
42 words
An electrical ribbon cable and connector assembly as in claim 1 wherein each of said connecting terminals is mounted on the same side of said recess thereby enabling said contact screws to contact said conductors from one side of said ribbon cable.
Claim 10
Dependent Claim
24 words
An electrical ribbon cable and connector assembly as in claim 6 wherein said contact screws are staggered along the longitudinal axis of said connector.
Claim 11
Dependent Claim
26 words
An electrical ribbon cable and connector assembly as in claim 6 further comprising means at each of said connecting terminals for clamping a respective external conductor.
Claim 12
Dependent Claim
35 words
An electrical ribbon cable and connector assembly as in claim 6 wherein said housing includes a removable protective cap for covering said connecting terminals and including at least one passage for receiving an external conductor.
Claim 13
Dependent Claim
33 words
An electrical ribbon cable and connector assembly as in claim 6 wherein said housing further includes an insulating support for supporting said connecting terminals and a removable cover mounted to said insulating support.
Claim 14
Dependent Claim
