Abstract
Abstract An interlocking crimp sleeve is disclosed for application to a terminated connector so as to apply an annular crimp securing the cable and particularly the cable shielding thereto. The subject sleeve is formed as an initially flat strip of metal stock having pre-formed opposite ends of an interlocking configuration. The strip is applied to the connector by bending around the electrical cable, engaging the interlocking end configurations and crimping the thus formed substantially cylindrical sleeve to provide the desired clamping and compression of the cable and engagement between the cable shield and connector shield.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
In combination with an electrical connector having a housing of insulative material with a plurality of terminal passages extending therethrough, a like plurality of electrical terminals each mounted in a respective passage, a multi conductor cable having each conductor thereof secured to a respective terminal, and a crimp sleeve capable of being applied to the cable other than axially from a free end and of being crimped to secure said cable to said connector, said crimp sleeve characterized by: an elongated strip of soft metal having interlocking profiles on the opposite ends thereof whereby said strip is applied to a previously terminated cable by folding it about said cable, interlocking said end profiles to form a substantially closed cylindrical crimp sleeve coaxially on said cable and crimping said sleeve to reduce the diameter thereof placing said interlocked ends under tension and said cable and connector under compression securing said cable to said connector.
Claim 2
Dependent Claim
153 words

Claim 3
Dependent Claim
43 words
An interlocking crimping sleeve according to claim 1 wherein: one end of said strip has at least one profiled projection; and the opposite end of said strip has a like number of recesses each profiled and aligned to receive a respective projection therein.
Claim 4
Dependent Claim
18 words
An interlocking crimping sleeve according to claim 1 wherein: said ends of said strip have a hermaphroditic profile.
Claim 5
Dependent Claim
51 words
An interlocking crimping sleeve according to claim 1 wherein: said soft metal is copper in the range of 0 to 2 on a hardness scale of 12 wherein 0 is annealed, 2 is 1/4 hard, 4 is 1/2 hard, 6 is 3/4 hard, 8 is full hard, and 12 is tempered.
Claim 6
Independent Claim
78 words
The method of securing a cable to a connector which has been preterminated by the cable comprising the steps of: forming a strip of relatively soft metal with interengaging profiles on the opposite ends thereof; folding said strip about said cable bringing said opposite ends into interlocking engagement to form substantially a closed cylindrical sleeve; and crimping said sleeve so as to apply tensile force to said interlocked ends and compressive force to said cable against said connector.
Claim 7
Independent Claim
78 words
The method of securing a cable to a connector which has been preterminated by the cable comprising the steps of: forming a strip of relatively soft metal with interengaging profiles on the opposite ends thereof; folding said strip about said cable bringing said opposite ends into interlocking engagement to form substantially a closed cylindrical sleeve; and crimping said sleeve so as to apply tensile force to said interlocked ends and compressive force to said cable against said connector.
Claim 8
Dependent Claim
26 words
A method according to claim 5 wherein said sleeve crimpingly secures a shielding layer of a shielded cable to a shield portion of a shielded connector.
