Abstract

Abstract A flat electrical cable for use under a rug or carpet having a series of regularly spaced elongate apertures in a web of insulating material along one edge of the cable. "U" shaped conductive connectors are used to secure adjacent cables together with an upper segment of the connector passing through an aperture of each cable so as to properly position the cables in respect to each other and electrically connect the cable conductors by means of sharpened pawls on the connector which pierce the plastics insulation of each cable.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 203 words
A connection of two electrically conductive flat cables and a connector therefor, each cable having an outer sheath of insulating material with at least one elongated flat electrical conductor embedded in said insulating material and a web portion, containing no conductor, extending along at least one elongate edge of the cable, said connection comprising: a series of elongated apertures through said web portion at spaced intervals along the length thereof; said connector being of an electrically conductive flat material bent into a generally "U" shape having two upper segments and a lower segment connected to said upper segments by bending portions; a plurality of upstanding sharpened pawls projecting from the inner surface of at least one of said upper or lower segments; the two upper segments being spaced apart a distance equal to the distance between two of said elongated apertures, the two upper segments passing through two of said elongated apertures and the upper and lower segments mechanically bent toward each other along the bending portions sandwiching therebetween end portions of the two adjacent flat cables with the sharpened pawls piercing said insulating material and contacting the embedded electrical conductors of both said cables and establishing an electrical connection between the conductors.
Claim 2
Dependent Claim 203 words
A connection of two electrically conductive flat cables and a connector therefor, each cable having an outer sheath of insulating material with at least one elongated flat electrical conductor embedded in said insulating material and a web portion, containing no conductor, extending along at least one elongate edge of the cable, said connection comprising: a series of elongated apertures through said web portion at spaced intervals along the length thereof; said connector being of an electrically conductive flat material bent into a generally "U" shape having two upper segments and a lower segment connected to said upper segments by bending portions; a plurality of upstanding sharpened pawls projecting from the inner surface of at least one of said upper or lower segments; the two upper segments being spaced apart a distance equal to the distance between two of said elongated apertures, the two upper segments passing through two of said elongated apertures and the upper and lower segments mechanically bent toward each other along the bending portions sandwiching therebetween end portions of the two adjacent flat cables with the sharpened pawls piercing said insulating material and contacting the embedded electrical conductors of both said cables and establishing an electrical connection between the conductors.
Claim 3
Dependent Claim 20 words
The connection of claim 1 in which the two adjacent flat cables are positioned end-to-end and held by said connector.
Claim 4
Dependent Claim 25 words
The connection of claim 1 in which the flat cables are multiconductor cables, each conductor having an adjacent web with said series of elongated apertures.
