Abstract
Transmission cable enclosure with a resiliently flexible cable sealing member within an inlet passage of a housing of the enclosure. The sealing member surrounds the cable when installed and a device is provided to apply a constant compressive force axially upon the sealing member. This constant force resiliently deforms the sealing member inwards to continuously seal against the cable irrespective of ambient temperature and pressure conditions. Also provided is a device for gripping the cable close to the sealing member to prevent axial movement of the cable at this location. The arrangement is suitable for passage of a single length or two closely positioned lengths of cable passing through the inlet passage.
Claims5
A transmission cable enclosure comprising
- a housing in a wall of the enclosure, the housing formed with an inlet passage having two ends for insertion of a cable through the wall of the enclosure;
- a resiliently flexible sealing member for location within the inlet passage of the housing in a position for surrounding the cable the sealing member being restrained from radially outwards deformation;
- means for applying a constant compressive force in an axial direction of the inlet passage upon the sealing member to cause the sealing member to be resiliently deformed radially inwardly of the inlet passage and into sealing contact with the cable;
- and means for gripping a part of the cable in a position axially spaced from the sealing member to hold the gripped part of the cable immovable relative to the housing;
- the gripping means comprising a clamping device locatable in an operating position axially beyond one end of the inlet passage and of the sealing member and a securing means operable to hold the clamping device in its operating position.
