Spliced shielded wire cable
View Patent ↗A wire harness having at least wire harness assembly having a splice of at least three shielded wire cables is presented. The assembly includes a flexible insulation layer wrapped about the joined core conductors of the three cables, a flexible conductive layer wrapped about the shield conductors of the cables, and a section of dual wall heat shrink tubing enclosing the flexible conductive layer and portions of the insulative jackets of the cables. The flexible conductive layer does not include any solder.
1. A wire harness assembly, comprising:
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;
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;
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, wherein the first core conductor is electrically and mechanically coupled to the second core conductor and the third core conductor;
a first flexible insulative layer overlaying the joined first, second, and third core conductors;
a second flexible insulative layer overlaying the first flexible insulative layer;
a flexible conductive layer overlaying the first, second, and third shield conductors;
a third flexible insulative layer overlaying a portion of the first flexible insulative layer and a first portion of the flexible conductive layer;
a fourth flexible insulative layer overlaying a portion of the second and third flexible insulative layer and a second portion of the flexible conductive layer; and
a section of dual wall heat shrink tubing in which the third and fourth flexible insulative layers and portions of the first, second, and third insulative jackets are disposed.
2. The wire harness assembly according to claim 1 , wherein the flexible conductive layer is formed of braided strands.
3. The wire harness assembly according to claim 1 , further comprising: a first ferrule overlaying the second insulative jacket; and a second ferrule overlaying the third insulative jacket and adjacent the first ferrule, wherein the first and second ferrules are also disposed within the section of dual wall heat shrink tubing.
4. The wire harness assembly according to claim 3 , wherein the second, third, and fourth flexible insulative layer and the first and second ferrules are formed of a section of heat shrink tubing, the first flexible insulative layer is formed of a cloth tape, and the flexible conductive layer is formed of braided strands.
