Electrical junction assembly for wiring harness

1. An electrical junction assembly for coupling one or more branch wires to a main trunk line, said junction assembly comprising:

an electrically insulative housing defining an internal cavity, said housing having a pair of trunk line openings and at least one branch opening, all of said openings communicating directly with said cavity;

a first trunk wire having an electrically conductive core strand surrounded by an insulating jacket, and a first trunk terminal affixed to said core strand thereof, said first trunk terminal extending into said cavity through said one of said trunk line openings;

a second trunk wire having an electrically conductive core strand surrounded by an insulating jacket, and a second trunk terminal affixed to said core strand thereof, said second trunk terminal extending into said cavity through the other of said trunk line openings and directly interlocking with said first trunk terminal in said cavity; and

a branch wire having an electrically conductive core strand surrounded by an insulating jacket, and a branch terminal affixed to said core strand thereof, said branch terminal extending into said cavity through said at least one branch opening and directly interlocking with at least one of said first and second trunk terminals in said cavity; and

wherein said first and second trunk terminals comprise respective female and male interlocking fittings.

2. The junction assembly of claim 1 wherein said cavity includes a generally axially extending main trunk passage with said first trunk opening at one end thereof and said second trunk opening at an opposite end thereof.

3. The junction assembly of claim 2 wherein said cavity includes at least one branch passage intersecting said main trunk passage, said branch opening communicating with said branch passage.

4. The junction assembly of claim 3 wherein said branch passage is oriented generally perpendicular to said axis of said main trunk passage.

5. The junction assembly of claim 3 wherein said cavity includes at least one hook disposed along said main trunk passage for snagging at least one of said first and second trunk terminals.

6. The junction assembly of claim 3 wherein said first and second trunk wires each include a cable seal configured to fully enclose said respective trunk line openings, and said branch wire includes a cable seal configured to fully enclose said branch opening.

7. The junction assembly of claim 1 wherein said male fitting of said second trunk terminal comprises an elongated blade member having at least one laterally extending barb.

8. The junction assembly of claim 7 wherein said branch terminal is configured to interlock directly with said barb of said blade member.

9. The junction assembly of claim 3 further including a mounting member extending from said housing and spaced from each of said trunk line openings.

10. The junction assembly of claim 9 wherein said mounting member is formed integrally with said housing.

11. The junction assembly of claim 10 wherein said mounting member includes a plurality of flexible fins extending from a common stalk.

12. The junction assembly of claim 11 wherein said stalk of said mounting member extending generally parallel to said branch passage.

13. The junction assembly of claim 12 wherein stalk is laterally offset from branch passage.

14. An electrical junction assembly for coupling a plurality of branch wires to a main trunk line, said junction assembly comprising:

an electrically insulative housing defining an internal cavity, said housing having a pair of trunk line openings and a plurality of branch openings, all of said openings communicating directly with said cavity; said cavity including a generally axially extending main trunk passage with one of said trunk line openings at one end thereof and the other of said trunk line openings at an opposite end thereof, and a plurality of branch passages intersecting said main trunk passage;

a mounting member extending integrally from said housing and spaced from each of said trunk line openings, said mounting member including a plurality of flexible fins extending from a common stalk;

a first trunk wire having an electrically conductive core strand surrounded by an insulating jacket, a first trunk terminal affixed to said core strand thereof, and a first cable seal disposed between said jacket and said first trunk terminal, said first trunk terminal extending into said cavity through said one of said trunk line openings;

a second trunk wire having an electrically conductive core strand surrounded by an insulating jacket, a second trunk terminal affixed to said core strand thereof, and a second cable seal disposed between said jacket and said second trunk terminal, said second trunk terminal extending into said cavity through the other of said trunk line openings and directly interlocking with said first trunk terminal in said cavity; and

a branch wire associated with each of said branch passages, each said branch wire having an electrically conductive core strand surrounded by an insulating jacket, a branch terminal affixed to said core strand thereof, and a third cable seal disposed between said jacket and said branch terminal, said branch terminal extending into said cavity through a respective one of said branch openings and directly interlocking with at least one of said first and second trunk terminals in said cavity; and

wherein said first and second trunk terminals comprise respective female and male interlocking fittings.

15. The junction assembly of claim 14 wherein said plurality of branch passages each intersect said main trunk passage and are all oriented generally parallel to one another.

16. The junction assembly of claim 14 wherein, said stalk of said mounting member is oriented generally parallel to said branch passages.
