Abstract
Abstract An electrical termination arrangement for flat cables which includes a generally U-shaped metallic member for each conductive track of the cable. Each metallic member has barbs formed on its legs which pierce the insulation and make electrical contact with the conductive track when the legs of the member are crimped to the flat cable. The U-shaped member may carry a pin or socket contact. Alternatively, the U-shaped member may be provided with an additional leg forming a Z-shaped member which interconnects the tracks of two flat cables.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A method of terminating a flat cable having a plurality of parallel, spaced conductive tracks thereon covered with insulation comprising the steps of: providing a termination device comprising a deformable flat metallic sheet bent to a U-shaped configuration providing a pair of flat spaced legs, said legs having generally parallel rows of barbs thereon, said rows being spaced apart a distance corresponding to the spacing of said conductive tracks; inserting the end of said cable between said legs with said tracks aligned with said rows of barbs; crimping said legs onto said cable end so that said barbs pierce said insulation and contact said conductive tracks; and removing the metal of said termination device between said tracks to electrically isolate said tracks from each other.
Claim 2
Independent Claim
125 words
A method of terminating a flat cable having a plurality of parallel, spaced conductive tracks thereon covered with insulation comprising the steps of: providing a termination device comprising a deformable flat metallic sheet bent to a U-shaped configuration providing a pair of flat spaced legs, said legs having generally parallel rows of barbs thereon, said rows being spaced apart a distance corresponding to the spacing of said conductive tracks; inserting the end of said cable between said legs with said tracks aligned with said rows of barbs; crimping said legs onto said cable end so that said barbs pierce said insulation and contact said conductive tracks; and removing the metal of said termination device between said tracks to electrically isolate said tracks from each other.
Claim 3
Dependent Claim
175 words
An electrical connection arrangement comprising: a pair of generally longitudinally aligned elongated flat cables each having a plurality of laterally spaced parallel conductive tracks covered with insulation, the tracks of said flat cables being generally longitudinally aligned with each other providing a plurality of aligned pairs of said tracks; a plurality of spaced generally Z-shaped deformable metallic strip members one for each of said aligned pairs of conductive tracks of said flat cables, each of said Z-shaped metallic members providing three flat, generally parallel legs; insulation piercing barbs on each of said legs extending toward the next adjacent leg; one end of one of said flat cables being positioned with its conductive tracks located between two adjacent legs of each of said metallic members; one end of the other of said flat cables being positioned with its conductive tracks located between the third leg of each said metallic member and the next adjacent leg thereto; and said legs of said metallic members being crimped together to electrically connect said aligned conductive tracks of said cables.
Claim 4
Dependent Claim
175 words
An electrical connection arrangement comprising: a pair of generally longitudinally aligned elongated flat cables each having a plurality of laterally spaced parallel conductive tracks covered with insulation, the tracks of said flat cables being generally longitudinally aligned with each other providing a plurality of aligned pairs of said tracks; a plurality of spaced generally Z-shaped deformable metallic strip members one for each of said aligned pairs of conductive tracks of said flat cables, each of said Z-shaped metallic members providing three flat, generally parallel legs; insulation piercing barbs on each of said legs extending toward the next adjacent leg; one end of one of said flat cables being positioned with its conductive tracks located between two adjacent legs of each of said metallic members; one end of the other of said flat cables being positioned with its conductive tracks located between the third leg of each said metallic member and the next adjacent leg thereto; and said legs of said metallic members being crimped together to electrically connect said aligned conductive tracks of said cables.
Claim 5
Dependent Claim
25 words
An electrical connection arrangement as set forth in claim 2 wherein: said ends of said flat cables are devoid of insulation between said metallic members.
Claim 6
Independent Claim
205 words
A method of connecting the ends of a pair of flat cables each having a plurality of parallel, spaced conductive tracks thereon covered wiTh insulation comprising the steps of: providing a connecting device comprising a deformable flat metallic sheet bent to a Z-shaped configuration providing three flat spaced generally parallel legs, said legs having generally parallel rows of barbs thereon, said rows being spaced apart a distance corresponding to the spacing of said conductive tracks; inserting the end of one of said cables between two of said legs of said connecting device with the tracks of said cable aligned with said rows of barbs; aligning said other cable with said one cable; inserting the end of said other cable between the third leg of said connecting device and the next adjacent leg with the tracks of said other cable aligned with said rows of barbs so that the tracks in said two cables are aligned; crimping said three legs onto said cable ends so that said barbs pierce the insulation on said cables and contact the conductive tracks thereof to electrically connect said tracks; and removing the metal of said termination device between said aligned tracks to electrically isolate said aligned tracks from each other.
