Method for splicing shielded wire cables
View Patent ↗A method of splicing shielded wire cables includes the steps of providing a first, second, and third shielded wire cable each having a core conductor axially surrounded by a shield conductor which is axially surrounded by an insulative jacket, providing a flexible insulation layer, a flexible conductive layer, and a section of dual wall heat shrink tubing. The first portion of the flexible insulation layer about the joined first, second, and third core conductors, wrapping the flexible conductive layer about the first, second, and third shield conductors, and disposing the flexible conductive layer and portions of the first, second, and third insulative jacket within the section of dual wall heat shrink tubing, thus forming a shielded wire cable splice.
1. A method of splicing a plurality of shielded wire cables, comprising the steps of:
providing a first shielded wire cable having a first core conductor at least partially axially surrounded by a first shield conductor which is at least partially axially surrounded by a first insulative jacket;
providing a second shielded wire cable having a second core conductor at least partially axially surrounded by a second shield conductor which is at least partially axially surrounded by a second insulative jacket;
providing a third shielded wire cable having a third core conductor at least partially axially surrounded by a third shield conductor which is at least partially axially surrounded by a third insulative jacket;
providing a flexible insulation layer;
providing a flexible conductive layer, wherein the flexible conductive layer does not include solder;
providing a section of dual wall heat shrink tubing;
wrapping a first portion of the flexible insulation layer about the joined first, second, and third core conductors;
wrapping the flexible conductive layer about the first, second, and third shield conductors;
disposing the flexible conductive layer and portions of the first, second, and third insulative jacket within the section of dual wall heat shrink tubing.
2. The method of claim 1 , further comprising the steps of:
wrapping a second portion of the flexible insulative layer about the first portion of the flexible insulative layer.
3. The method of claim 2 , wherein the first portion of the flexible insulative layer is formed of a cloth tape.
4. The method of claim 3 , further comprising the steps of:
wrapping a third portion of the flexible insulative layer about a portion of the first insulative layer and a first portion of the flexible conductive layer.
5. The method of claim 4 , further comprising the steps of:
wrapping a fourth portion of the flexible insulative layer about a portion of the second and third insulative layer and a second portion of the flexible conductive layer.
6. The method of claim 5 , wherein the second, third, and fourth portions of the flexible insulative layers are formed of a section of heat shrink tubing.
7. The method of claim 6 , wherein the fourth portion of the flexible insulative layer has a larger diameter than the third portion of the flexible insulative layer prior to shrinking.
8. The method of claim 1 , further comprising the steps of:
providing a first ferrule and a second ferrule
wrapping the first ferrule about the second insulative layer; and
wrapping the second ferrule about the third insulative layer adjacent the first ferrule.
9. The method of claim 8 , wherein the first and second ferrules are formed of a section of heat shrink tubing.
10. The method of claim 8 , wherein the first and second ferrules are disposed within the section of dual wall heat shrink tubing.
11. The method of claim 1 , wherein the flexible conductive layer is formed of braided strands.
