A multiple joint box or distribution sleeve having a tubular sleeve, which has a longitudinal slit with wedge-shaped sealing elements along the slit, and sealing members at both ends of the tubular sleeve characterized by each of the sealing members comprising a pair of rigid disks and at least one elastic circular plate interposed and clamped therebetween, the disks and plate each having a plurality of apertures aligned with each other to form cable inlets with the apertures of the elastic circular plate having a smaller diameter than the aperture of the rigid disks, and each of the disks being provided with a peripheral bevel coacting with each other to form a circular groove for receiving means for forming a peripheral seal.

Multiple joint box utilizing a thermoplastic clamping sleeve principle

A clamping tool having a bracket arm with a stationary jaw at one end thereof. The bracket arm supports a movable jaw. Each of the jaws have slot openings with grasping means for use in applying tension clamps to cable members. The tool is modified to enable it to function as a cable fitting opening device through the provision of projections attachable to the jaws which projection can be urged towards one another by movement of the movable jaw to urge the projections into contact with projections or recesses of cable fittings to force the cable fittings to open.

Tool for opening cable fittings

A cylindrical-shaped cable sleeve, made of a suitable plastic, is formed by mating two semi-circular sleeve portions. With suitable cables inserted through an opening at each end and spliced therein, the two sleeve portions are secured from separation by a suitable clamping device engaging longitudinal mating flanges running on the exterior surface on each side of each half portion. The cable splice is sealed within the sleeve by insertion of a suitable sealant which is prevented from leaking by a series of axially disposed sealing rings interfacing with the cable to form a joint.

Cable sleeve

A sealing member for effecting a gas-tight closure about a cable at an inlet to a hollow cable sleeve fitting. The member is annular in form and is divided on a plane parallel to the cable axis for assembly about the cable after boring a selected passage for the cable through the member. The sealing member has a plurality of radially- and circumferentially-continuous, radially outwardly-extending, longitudinally-spaced ribs engageable via a coating of plastic potting compound with an inner surface of the inlet fitting. The ribs are held in spaced relation by an integral reinforcement member which is spaced radially inwardly of the outer circumference of the ribs. A center portion of the reinforcement member is apertured so that selective boring through of the member to form a cable passage will leave internal radial ribs for bearing against the cable via a second plastic potting compound. Any number and size of cable passages may be provided for.
