Abstract
Abstract A method and apparatus for providing strain relief to a cable splice area is disclosed. A length of flexible cord is secured to the cable on each side of the splice. A frictional substrate is supported over the cord and the cable. The frictional substrate is compressily secured to the cable thereby frictionally supporting the cord to the cable.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
94 words
A method of strain relieving a splice area of a cable having a plurality of conductors surrounded by an outer insulated jacket, the method comprising the steps of: placing a length of flexible cord across the cable splice; securing each end of said flexible cord to said cable jacket, at a position adjacent from said cable splice; placing a frictional substrate on said cable jacket, over said flexible cord adjacent each end of said cable splice; and applying compressive fastening means to said cable, over said frictional substrate on each side of said splice.
Claim 2
Independent Claim
94 words
A method of strain relieving a splice area of a cable having a plurality of conductors surrounded by an outer insulated jacket, the method comprising the steps of: placing a length of flexible cord across the cable splice; securing each end of said flexible cord to said cable jacket, at a position adjacent from said cable splice; placing a frictional substrate on said cable jacket, over said flexible cord adjacent each end of said cable splice; and applying compressive fastening means to said cable, over said frictional substrate on each side of said splice.
Claim 3
Dependent Claim
14 words
A method in accordance with claim 1 wherein said flexible cord is aramid fiber.
Claim 4
Dependent Claim
32 words
A method in accordance with claim 2 wherein said securing step includes looping each end of said cord around each end of said cable at a location spaced from said splice area.
Claim 5
Dependent Claim
14 words
A method in accordance with claim 1 wherein said frictional susbstrate is emery cloth.
Claim 6
Dependent Claim
24 words
The method in accordance with claim 1 wherein said placing step further includes: securing said frictional substrate to said cable jacket with vinyl tape.
Claim 7
Dependent Claim
35 words
A method in accordance with claim 1 wherein said applying step further includes placing a cable tie around said cable adjacent each side of said splice and compressively securing said cable ties to said cable.
Claim 8
Independent Claim
111 words
A method of providing strain relief across an exposed portion of an electrical cable comprising the step of: selecting a length of flexible cord; placing a knot in each end of said flexible cord; looping each said end of said cord around said cable on opposite sides of said exposed portion loosely securing each end to said cable; pulling said loosely secured ends of said cord apart to remove any slack therebetween; wrapping an abrasive cloth strip around said cord and said cable adjacent each of said looped ends; and applying a compression strap around said cloth strip, said flexible cord and said cable on each side of said exposed area.
Claim 9
Independent Claim
111 words
A method of providing strain relief across an exposed portion of an electrical cable comprising the step of: selecting a length of flexible cord; placing a knot in each end of said flexible cord; looping each said end of said cord around said cable on opposite sides of said exposed portion loosely securing each end to said cable; pulling said loosely secured ends of said cord apart to remove any slack therebetween; wrapping an abrasive cloth strip around said cord and said cable adjacent each of said looped ends; and applying a compression strap around said cloth strip, said flexible cord and said cable on each side of said exposed area.
Claim 10
Dependent Claim
16 words
A method in accordance with claim 7 wherein said flexible cord is unidirectionally woven aramid fiber.
Claim 11
Dependent Claim
22 words
A method in accordance with claim 7 wherein said looping step further includes: knotting each end of said cord around said cable.
Claim 12
Dependent Claim
21 words
A method in accordance with claim 7 including the step of securing said abrasive cloth to said cable over said cord.
Claim 13
Dependent Claim
74 words
In a splice for an electrical cable having a jacket surrounding a plurality of conductors, a strain relief apparatus comprising: a length of flexible cord supported on said cable jacket and secured across splice; a frictional substrate supported on said cable jacket over said flexible cord adjacent each side of said splice; and compressive fastening means for securing said frictional substrate and said cord to said cable jacket on each side of said splice.
Claim 14
Dependent Claim
74 words
In a splice for an electrical cable having a jacket surrounding a plurality of conductors, a strain relief apparatus comprising: a length of flexible cord supported on said cable jacket and secured across splice; a frictional substrate supported on said cable jacket over said flexible cord adjacent each side of said splice; and compressive fastening means for securing said frictional substrate and said cord to said cable jacket on each side of said splice.
Claim 15
Dependent Claim
13 words
An apparatus in accordance with claim 11 wherein said cord is aramid fiber.
Claim 16
Dependent Claim
27 words
An apparatus in accordance with claim 11 wherein said cord includes a looped portion on each side of said splice for securing said cord to said jacket.
Claim 17
Dependent Claim
14 words
An apparatus in accordance with claim 11 wherein said frictional substrate is emery cloth.
Claim 18
Dependent Claim
30 words
An apparatus in accordance with claim 11 wherein said compressive fastening means comprises a cable tie for circumferentially engaging said frictional substrate and frictionally supporting said cord against said jacket.
