The sealing interface (26) is configured to provide effective sealing while requiring only relatively low amounts of force to deform the elastomeric sealing member (28) sufficiently to form an effective seal.
Abstract:
The present invention relates to a cable sealing device for sealing a passage of a cable, to a cable termination provided with the cable sealing device and to an attaching device securable to a cable for supporting an installing of the cable sealing device on the cable. The cable sealing device is simply mountable on a cable providing an attaching part and reliably securable on the cable in its circumferential and longitudinal directions. The cable sealing device (10) comprises a sealing part (11) providing a passageway with an inner seal (14) through which a cable (2) is sealingly guidable, and an outer seal (15) arranged on an outer circumference of the sealing part (11). The cable sealing device (10) is characterized by a fixation part (12) adapted to be mountable on an attaching part (4) securable to the cable (2) and providing accessible outer positive locking faces (5, 6) extending in circumferential and longitudinal direction of the cable (2), wherein the fixation part (12) provides inner circumferential and axial abutment faces adapted to co-operate with the outer positive locking faces (5, 6) so as to provide therebetween a positive locking in circumferential and longitudinal direction. The fixation part (12) has first securing means (18) for co-operating with second securing means (19) provided with the sealing part (11) to secure the sealing part (11) in circumferential and longitudinal direction against the fixation part (12).
Abstract:
An enclosure (20, 220) includes a housing (22, 222) and a sealing unit (48, 42a, 232) that mounts within a sealing unit opening (28, 230) of the housing. The sealing unit (48, 42a, 232) provides a peripheral seal between the housing (22, 222) and the sealing unit (48, 42a, 232) and provides seals around cable ports (50). The sealing unit (48, 42a, 232) can be mounted to and removed from the housing (222) through the sealing unit opening (28, 230). The base (26) lacks a permanent retention structure (55, 155a) at the outer end of the base (26) for retaining the sealing unit (48, 42a, 232) in the base (26). A cover (24) is removable from the base (26) without requiring the sealant arrangement (52, 236) to be de-pressurized. A fastening arrangement (55, 155a) releasably retains the sealing unit (48, 42a, 232) in the sealing unit opening (28, 230).

The wrap (68) wraps around the jacket (48) and is adjustable for different jacket diameters. The strength member clamp assembly (80, 180, 280) is mountable in a plurality of positions relative to the jacket clamp assembly (64, 164, 264) to account for variations in the relative location of the strength member relative to the jacket clamp assembly. The clamp assembly (60, 160, 260) is moveable relative to the frame (30) wherein the cable (46) is allowed to move to a proper position relative to the seal block (40) so as to reduce the likelihood of a leak by being centrally positioned relative to the cable opening through the seal block.

A trigger (70) pushes the inner ring (60) to compress the blown fiber tubes (20) between the inner ring (60) and the outer ring (50). The outer ring (500 and the inner ring (60) each include a plurality of spaced pockets (52, 68) each sized for receipt of a blown fiber tube (20). The trigger (70) includes a threaded member (80) which pushes the inner ring (60) outwardly. In one embodiment, portions (64) of the inner ring (60) separate during activation and press against the blown fiber tubes (20) to compress the blown fiber tubes (20) against the outer ring (50). A spring (496) may be added to push on the inner ring (60). Anti-rotation and lock features are provided for the compression, sealing and fixation mechanisms.
