ABSTRACT:
Sealing member for an electric cable having an outer relief surface formed by an array of electrical conductors in a spaced apart relationship concentrically laid over an insulating sheath of the electric cable. The sealing member comprises a collar of flexible and resilient material including a plurality of elongated cavities spaced apart by a distance corresponding substantially to a spacing between electrical conductors of the array, and an outer sealing surface of a generally cylindrical configuration. The collar engages the electric cable concentrically, whereby electrical conductors of the array are caused to enter into respective cavities of the collar which is capable of forming a non-leaking union between the electric cable and an adjacent body in a mating relationship with the collar. The invention also extends to a sealing assembly to form a fluid-tight seal between the electric cable and a surrounding enclosure. The invention further extends to a method for sealing the electric cable to the surrounding enclosure.
