Abstract

An electrical assembly that includes a substrate having an aperture. A flat conductor is mounted to the substrate and extends over at least a portion of the aperture, with a ring terminal in contact with the flat conductor adjacent to the aperture. A lead wire connects to the ring terminal and is spaced from the substrate, and a fastener extends through the ring terminal and flat conductor, secured in the aperture, and securing the ring terminal against the flat conductor.

First claim

The invention claimed is:

1. An electrical assembly comprising:
a substrate having an aperture;
a flat conductor mounted to the substrate and extending over at least a portion of the aperture;
a ring terminal in contact with the flat conductor adjacent to the aperture;
a round lead wire connected to the ring terminal;
a fastener extending through the ring terminal and flat conductor, secured in the aperture, and securing the ring terminal against the flat conductor, wherein the fastener is made of an electrically conducting material and an electrically non-conducting material is located in the aperture between the fastener and an electrically conducting portion of the substrate; and
wherein an anchor, which is electrically insulative, is mounted in the aperture and the fastener extends into a cavity in the anchor, and wherein an outer surface of the anchor is a truncated conical shape.

2. The electrical assembly of claim 1 wherein the aperture is a hole through the substrate and the fastener extends through at least a portion of the substrate.

3. The electrical assembly of claim 2 wherein the fastener is a rivet having a first head formed to secure the rivet to the substrate and a second head under which the flat conductor and the ring terminal are in contact.

4. The electrical assembly of claim 1 wherein the fastener is a push pin and includes a barb that engages with the anchor to retain the push pin in the substrate.

5. The electrical assembly of claim 1 wherein the fastener is a push pin having a head under which the flat conductor and the ring terminal are in contact, and at least one barb that secures the push pin in the substrate.

6. The electrical assembly of claim 1 wherein the substrate includes a metal vehicle body portion and paint coating the metal vehicle body portion.

7. The electrical assembly of claim 1 wherein the electrically non-conducting material located in the aperture is paint.

8. An electrical assembly comprising:
a substrate having an aperture;
a flat conductor mounted to the substrate;
a terminal in contact with the flat conductor adjacent to the aperture;
a round lead wire connected to the terminal; and
a fastener secured in the aperture, securing the terminal against the flat conductor, wherein the fastener is made of an electrically non-conducting material; and
wherein an anchor, which is electrically insulative, is mounted in the aperture and the fastener extends into a cavity in the anchor, and wherein an outer surface of the anchor is a truncated conical shape.

9. The electrical assembly of claim 8 wherein the outer surface of the anchor is shaped as back-to-back truncated conical shapes.

10. An electrical assembly comprising:
a substrate having an aperture;
a flat conductor mounted to the substrate and extending over at least a portion of the aperture;
a ring terminal in contact with the flat conductor adjacent to the aperture;
a round lead wire connected to the ring terminal;
a fastener extending through the ring terminal and flat conductor, secured in the aperture, and securing the ring terminal against the flat conductor, wherein the fastener is made of an electrically conducting material and an electrically non-conducting material is located in the aperture between the fastener and an electrically conducting portion of the substrate; and
wherein an anchor, which is electrically insulative, is mounted in the aperture and the fastener extends into a cavity in the anchor, and wherein an outer surface of the anchor is shaped as back-to-back truncated conical shapes.
