Abstract:
1. A cable seal assembly, comprising: an outer housing having a through bore of a first diameter; an annular seating cavity in the though bore having opposite axial end walls and an inner surface of a second diameter greater than the first diameter; a cable extending through the bore in the housing, the cable having an outer surface of diameter slightly less than the first diameter; and a tubular seal member of elastomeric material, the seal member having at least one axial slit thereby forming opposing radially extending surfaces of the seal member, the seal member seated in the cavity and squeezed between the outer surface of the cable and the opposing inner surface of the cavity, the seal member having an inner surface which directly engages and seals against the outer surface of the cable and an outer surface which directly engages and seals against the inner surface of the annular seating cavity of the housing, and opposite axial end faces; and the seal member having a radial cross sectional area in a non-squeezed condition greater than the radial cross sectional area defined between the outer surface of the cable and the inner surface of the cavity, whereby pressure is induced between the inner and outer surfaces of the seal, the opposing radially extending surfaces at the axial slit, and the opposing surfaces of the cable and cavity when the cable is extended through the seal member.
