Abstract: A tap connector for use with a range of conductor diameters having a yoke comprising a pair of opposed plates extending angularly from a pad. A flat spring is attached to the terminal ends of each of the plates and extends towards the pad and is spaced from the inner face of the plates a predetermined distance. The springs terminate in an arcuate configuration so as to accommodate the conductor under a predetermined constant pressure. The pad is connected to a ground cable. High amperages caused by lightning or short circuits create an electromechanical force which drives the terminal ends of the springs toward each other so as to provide higher mechanical pressure about the conductor under such fault conditions.

Abstract: An electrical bus includes a receptacle for mating with an external electrical connector. This receptacle defines an entrance and a tapering inner wall portion diverging inwardly of the entrance. A connecting adapter member comprises a first portion whose external periphery presents flat surfaces for engagement by a tool, and a second portion comprising a plurality of elongate tapered segments. The elongate tapered segments define a central bore and a peripheral surface generally congruent with the inner wall surface of the receptacle. The segments are resiliently inwardly compressible to effect mating with the receptacle, so as to hold the adapter member rotatably in captive relation therein. The central opening is threaded to receive a complimentarily threaded stud as for example, a transformer connector stud. Upon inserting the adapter member in captive relation in the bus receptacle, a tool is applied to the tool receiving portion thereof and the adapter rotated to threadingly engage the stud member.
