ELECTRICAL BUSHING ASSEMBLY

摘要

The assembly is designed to be received in a circular opening in a wall of a casing for electrical apparatus, and comprises an elongated generally cylindrical bushing of insulating material molded about a cylindrical central portion of an elongated conductor with internal sealing and locking means therebetween. The bushing assembly seats in an annular recess formed by a stepped boss surrounding the opening, and the assembly is removably held in position by a snap-ring which also maintains sealing pressure on an O-ring positioned between the bushing and the inner wall of the boss. Peripherally-spaced projections on the bushing are received in respective complementary recesses formed in the inner wall of the boss to prevent rotary motion of the assembly with respect to the casing.
