An optical cable connection box (1) with an auxiliary device for gap filling and waterproofing is provided. The connection box includes at least one cable accessing end face (2), at least one auxiliary device for gap filling and waterproofing and at least one elastic shrinkable tube (4). The end face (2) is provided with a first hollow tubular column (3), and an optical cable to be waterproof processed by the elastic shrinkable tube (4) passes through the hollow tubular column (3) in the form of dual cable (5) after face to face bending, so that cable halfway splitting and halfway branching can be processed in the box without cutting off the cable. The auxiliary device cooperates with the optical cable in the hollow tubular column (3), and a first waterproof structure is formed at the place where the auxiliary device is wrapped by the elastic shrinkable tube (4). At least the outside of the first hollow tubular column (3) and at least a portion of the auxiliary device are also wrapped by the elastic shrinkable tube (4) to form a second waterproof structure. The connection box provides a better waterproof effect and reduced cost.

The present invention relates to a joint arrangement (1) for a submarine cable, in which armoured submarine cables are joined together, said joint arrangement comprising a tubular enclosure (5) into which two submarine cables to be joined are to extend and inside which conductors of the two submarine cables are joined, wherein said enclosure (5) comprises a current-carrying part (11) arranged so as to be able of conducting at least a part of a current conducted by the armouring (10) of the cables, and a reinforcement part (12) provided to provide sufficient mechanical strength to said enclosure (5) and made of a material of lower electrical conductivity than the material of the current-carrying part (11). The current-carrying part (11) is integrated in said reinforcement part (12) and forms a single unit therewith.

Sealed cable connections can be used to connect first and second cables to a sealed cable joint. The sealed cable connection at one end of the sealed cable joint (10) includes a cable socket body (30) positioned within an inner region of a housing (20). The cable socket body includes a passageway receiving one of the cables. A seal securing member (36) is positioned within the inner region of the housing and secured into contact with the cable socket body. At least one seal (40), such as a resilient metal seal, is compressed between the cable socket body and the seal securing member to seal against the inner surface of the housing. The sealed cable connection can also include a cable seal positioned around the cable and within the passageway of the cable socket body.

The invention concerns a device for sheathing a wire line element comprising: a shell defining in its inner part a chamber for receiving the element (4) and consisting at least partly of two partial shells (5, 6) capable of being tightly fixed to each other by axial clamping, having each an orifice (21, 22) to allow the wire to pass through, a sealing lining (9, 10) around each orifice; and two packing boxes (7, 8) axially mobile inside the shell, associated with each of the orifices, and provided with at least indirect mutual pressing means (24, 25) so that the axial clamping of the partial shells stresses the linings after the packing boxes have been pressed together.

The center component 18a around the connector 2 is made of an insulating material such as synthetic resin, and there is a middle flange 19 formed around its middle section that protrudes outward in the radial direction around its entire circumference. There are insulating-tube side flanges 21, 21 that are formed around the opening ends of external semiconductive layers 13a, 13a of the insulating tubes 20a, 20a at the ends of the cables 4, 4, respectively. These insulating-tube side flanges 21, 21, are connected and joined to the middle flange 19 with O-rings 25, 25 therebetween.

A bond bar assembly (116) spans an electrical cable splice (14). The bond bar assembly includes a conductive bond bar (116) having opposed ends and a longitudinal central extent which spans the cable splice. Each end of the bond bar has a generally planar surface for engagement with the cable. A radially contractable clamping member is securable about the cable (10) and about the planar surface of each bond bar end for securing the bond bar ends to the cable. The planar surface of each bond bar end includes a deflectable jacket skiving member (140) which is deflectably movable from a first position in non-skiving engagement with the jacket of the cable to a second position in skiving engagement with the cable jacket upon the radial contraction of the clamping member. Such arrangement positionally confines and secures the bond bar with respect to the cable (10).
