Abstract

A method of manufacturing a grounding connection is disclosed that comprises assembling a non-ferrous grounding connector to a non-ferrous part, and melting brazing material between the grounding connector and the part to secure the grounding connector to the part. The step of assembling the connector to the part may be performed by clinching the connector to the part. The ground connector may comprise a nut secured to the vehicle body by a clinch joint and a deposit of braze metal applied to the nut at the location of the clinch joint. Alternatively, the ground connector for a vehicle body may comprise a nut defining an opening for receiving a fastener and a deposit of brazing material attaching the nut to the vehicle body.

First claim

What is claimed is:

1. A method of manufacturing a grounding connector including a non-ferrous nut, a screw, and a wire terminal to a part comprising:
assembling the nut to a non-ferrous part;
melting a brazing material between the nut and the part to secure the grounding connector to the part; and
connecting the screw, and wire terminal to the nut, wherein the nut has a plurality of sides extending between an attachment surface and an outer surface of the nut that define a plurality of channels, respectively, and wherein the brazing material is melted to flow through the channels.

2. The method of claim 1 wherein the step of assembling the connector to the part is performed by clinching the nut to the part.

3. The method of claim 1 wherein the non-ferrous part is a heat-treated aluminum alloy, and the brazing material has a melting point of between 700° and 900° F.

4. The method of claim 1 wherein the nut further includes a plurality of feet provided on the nut that are formed of the brazing material that melt during the melting step.

5. The method of claim 1 further comprising a braze washer inserted between the ground connector and the part, and wherein the braze washer provides the brazing material that melts in the melting step.
