Reduced mechanical stress bushing and conductor rod assembly

摘要: An improved, failure-resistant, low mechanical stress electrical connector bushing (10) is provided which includes an elongated, central metallic conductor rod (12) with insulative epoxy body (14) cast about the (12). The of substantially constant diameter throughout its length, and a male connection end (16) opposed female (18). (18) presents upset, integral, cold-forged, radially expanded terminal portion (20) having greater than (12), butt face (24). Stress analysis confirms that develops reduced, thermally induced stresses, as compared prior design.
