Abstract An internally threaded metal sleeve is rigidly mounted in a passage through an insulating bushing and extends outwardly to an end of the passage or beyond it. The bushing is intended to be mounted in the wall of electrical apparatus, with the outer end of the sleeve outside. Screwed into the sleeve and projecting from its outer end is a threaded stud that carries a nut which presses tightly against the outer end of the sleeve. Outwardly of the nut the stud is provided with a groove that weakens it, and a pair of nuts mounted on the stud outwardly of the groove are for holding an electric cable terminal which, if enough tension is applied to it, will cause the stud to break at its weakening groove without damaging the sleeve or bushing.
An electrical connector comprising an insulating bushing provided with a passage therethrough, an internally threaded metal sleeve rigidly mounted in said passage and extending outwardly at least to an end of it, means for rigidly mounting the bushing in the wall of electrical apparatus with said end of the passage outside, a threaded stud screwed into said sleeve and projecting from its outer end, a nut on the stud pressing tightly against the outer end of the sleeve, the stud outwardly of the nut being provided with a circumferential groove reducing the cross-sectional area of the stud to weaken it, a second nut on the stud outwardly of said groove, the outer end of the stud being adapted to receive a nut for holding an electric cable terminal on the stud against said second nut, and means for making an electrical connection to the opposite end of the stud.
