Abstract

A wiring harness assembly includes a plurality of separated conductors formed of an electrically conductive material, a substrate formed of a dielectric material encasing the plurality of separated conductors, a location feature integrally formed with the substrate and an opening defined in the substrate having a predetermined size and shape. A section of the plurality of separated conductors is exposed within the opening. The opening is precisely located relative to the location feature.

First claim

We claim:

1. A wiring harness assembly, comprising:
a plurality of plurality of electrically conductive wires formed of a first electrically conductive material;
a substrate formed of a dielectric material encasing the plurality of separated conductors;
a location feature integrally formed with the substrate;
an opening defined in the substrate having a predetermined size and shape, wherein a section of the plurality of separated conductors is exposed within the opening and wherein the opening is precisely located relative to the location feature; and
a connector having a lower segment disposed within the opening, wherein the connector is secured to the substrate, wherein the lower segment includes a cradle feature that is in mechanical contact with a lower portion of the plurality of electrically conductive wires, thereby supporting the plurality of electrically conductive wires.

2. The wiring harness assembly according to claim 1 , wherein the opening is surrounded by the substrate.

3. The wiring harness assembly according to claim 1 , wherein the lower segment is integrally formed with the substrate.

4. The wiring harness assembly according to claim 1 , wherein the plurality of electrically conductive wires is arranged and maintained is a predetermined order.

5. The wiring harness assembly according to claim 1 , wherein a first region of the substrate surrounding the opening has a stiffness that is greater than a second region of the substrate remote from the opening.

6. The wiring harness assembly according to claim 1 , wherein the connector further comprises an upper segment secured to the lower segment, wherein the upper segment includes a plurality of terminals, and wherein each terminal in the plurality of terminals is in mechanical and electrical contact with a wire in the plurality of electrically conductive wires.

7. The wiring harness assembly according to claim 6 , wherein the upper segment is received within the lower segment.

8. The wiring harness assembly according to claim 6 , wherein the connector is mated with a corresponding mating connector having a plurality of corresponding mating terminals mated with the plurality of terminals.

9. The wiring harness assembly according to claim 6 , wherein the lower segment comprises a lower seal formed of a first compliant material and sealing engaging a lower inner surface of the substrate within the opening and wherein the upper segment comprises an upper seal formed of a second compliant material and sealing engaging an upper inner surface within the opening.

10. The wiring harness assembly according to claim 6 , further comprising an inner seal formed of a third compliant material intermediate the upper segment and the lower segment.

11. The wiring harness assembly according to claim 6 , wherein each terminal in the plurality of terminals defines a forked end having two tines, wherein a wire of the plurality of electrically conductive wires is received between the two tines, and wherein the wire is compressively engaged by the two tines.

12. The wiring harness assembly according to claim 11 , wherein the lower segment defines a plurality or recesses in which the two tines are received.

13. The wiring harness assembly according to claim 11 , further comprising a coating on outer surfaces of the plurality of electrically conductive wires formed of a second electrically conductive material, wherein the second electrically conductive material has a lower melting point than the first electrically conductive material.

14. The wiring harness assembly according to claim 13 , wherein one terminal in the plurality of terminals is metallurgically bonded to one electrical conductor in the plurality of electrically conductive wires by localized heating of the coating.

15. The wiring harness assembly according to claim 6 , wherein the upper segment comprises an electrical device directly connected to the plurality of terminals.

16. The wiring harness assembly according to claim 15 , wherein the electrical device is selected from a list consisting of a relay, an electronic controller, an electronic sensor, a lighting device.

17. The wiring harness assembly according to claim 6 , wherein the lower segment comprises a lower lip engaging a lower surface of the substrate around a perimeter of the opening and wherein the upper segment comprises an upper lip engaging an upper surface of the substrate around the perimeter of the opening.

18. The wiring harness assembly according to claim 17 , wherein the lower lip comprises a lower seal formed of a first compliant material and sealingly engaging the lower surface of the substrate around the perimeter of the opening and wherein the upper lip comprises an upper seal formed of a second compliant and sealingly engaging the upper surface of the substrate around the perimeter of the opening.

19. The wiring harness assembly according to claim 1 , wherein the substrate is formed by an additive manufacturing process.

20. The wiring harness assembly according to claim 19 , wherein the additive manufacturing process is selected from a list consisting of 3D printing, stereolithography, digital light processing, fused deposition modeling, fused filament fabrication, selective laser sintering, selecting heat sintering, multi-jet modeling, multi-jet fusion, electronic beam melting, and laminated object manufacturing.
