Abstract
A simplified electrical high voltage loadbreak bushing insert connector is disclosed which provides an improved electrical current path between a bushing well and a male probe contact during fault and activated closure while eliminating the usual prior art internal conductive sleeve contact. A solid contact, directly coupled to a bushing well stud, electrically engages a tubular extension of the movable female contact assembly during movement of the assembly over its entire range. In a first group of embodiments, contact is made with the interior of the tubular extension while in others with the exterior. Various stop member arrangements are disclosed to limit movement of the female contact assembly and of joining the solid contact to the insert body.
