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