High voltage cable connector

Abstract

A connector for electrically connecting a high voltage cable to an electrical apparatus bushing with a threaded opening, the connector comprising a housing having a passage having one end formed to sealingly engage the bushing, and an electrically conductive cable connecting element positioned in the housing and extending partially into the first passage. The cable connecting element is adapted to be electrically connected to the high voltage cable. The connector also includes a bushing connecting member mounted in the passage and adapted to be rotated. The connecting member includes a body portion electrically connected to the cable connecting element, and a threaded portion connected to the body portion and adapted to engage the threaded opening in the bushing. The bushing connecting member also includes a lead portion connected to the threaded portion and having such an axial length and a diameter significant to insure the maximum amount of possible misalignment between the bushing threaded opening and the bushing connecting member is at most about one-half a degree. The threaded portion also has a blunt lead thread and the axial length of the threaded portion is of sufficient length so that the threaded portion engages the bushing opening before the connector housing contacts the bushing.
