An optical cable connection box with an auxiliary device for gap filling and waterproofing is provided. The connection box includes a cable accessing end face, an auxiliary device for gap filling and waterproofing and an elastic shrinkable tube. The end face has a first hollow tubular column, and an optical cable to be waterproof processed by the elastic shrinkable tube passes therethrough as a dual cable 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 column, formerly a first waterproof structure where the auxiliary device is wrapped by the elastic shrinkable tube. At least the outside of the first hollow column and at least a portion of the auxiliary device are also wrapped by the elastic shrinkable tube forming a second waterproof structure.

According to techniques of the present application, an apparatus for covering at least a portion of a cord includes a lower portion and an upper portion. The lower portion may include a bowl region having an upper rim. The lower portion may also include flexible tabs that substantially surround or completely surround the upper rim. Each of the flexible tabs may extend outwardly or downwardly from the upper rim. The upper portion may have a lower rim that extends below the outer edges of each of the flexible tabs when the upper portion is engaged to the lower portion. The upper portion may contact each of the flexible tabs when the upper portion is engaged to the lower portion. The apparatus may include a securing member extending downwardly from the lower portion to secure the apparatus to a resting surface.

A grade level enclosure conversion assembly adapted for converting a pedestal housing between a flush-to-grade and an above-ground pedestal installation. The base of the pedestal housing carries a plug removably mounted to a swing-arm in the grade level enclosure. The swing-arm holds the pedestal assembly in a stored position in the flush-to-grade installation, containing wiring for service connections. To convert to the above-ground installation, a solid grade level cover plate lid is removed, and the pedestal assembly is rotated on the swing arm to a raised position from which it can be removed from the swing-arm (along with the wiring) and fed through an access opening in a separate cover plate lid. The plug on the pedestal housing is then positioned in the access opening to hold the pedestal assembly in the above-ground position. A series of separate fiber optic splice connections, or other underground utility service connections, can be made when rotating the pedestal between the stored position and the above-ground position.

A cable connector includes a housing, a first screwed cable gland for receiving a first cable, and a second screwed cable gland for receiving a second cable. The first cable can be connected to the second cable using a contact device. The cable connector also includes a locking device which, when screwing at least one screwed cable gland to the housing, locks said screwed cable gland to the housing so that the cables are mounted on the housing in a protected manner.

A joint arrangement for a submarine cable, in which armoured submarine cables are joined together, the joint arrangement including a tubular enclosure into which two submarine cables to be joined are to extend and inside which conductors of the two submarine cables are joined, wherein the enclosure includes a current-carrying part arranged so as to be able of conducting at least a part of a current conducted by the armouring of the cables, and a reinforcement part provided to provide sufficient mechanical strength to the enclosure and made of a material of lower electrical conductivity than the material of the current-carrying part. The current-carrying part is integrated in the reinforcement part and forms a single unit therewith.

For a longitudinal water barrier a conductor is cut at the desired location as usual, the insulation is stripped and the corresponding leads are reconnected with one another in an electrically conductive manner. However, the following steps are taken for additional sealing: each lead end is applied to a soldering surface of a circuit board, wherein the soldering surfaces are separated from one another through slots in the circuit board; and, subsequently in particular a two step encasement with plastic material is performed over the entire connection portion.

A fitting for coupling ends of insulated conductors includes a sleeve to couple an end of a jacket of a first insulated conductor to an end of a jacket of a second insulated conductor. The sleeve is located between end portions of the insulated conductors. At least one of the ends of the sleeve is angled relative to the longitudinal axis of the sleeve. The sleeve has a longitudinal opening that extends along the length of the sleeve substantially the distance between end portions of the jackets of the insulated conductors. The longitudinal opening allows electrically insulating material to be filled into the sleeve.

A fast connecting structure for fitting lights, each lamp pipe of a fitting light can be made a specific length in a factory, such as 2 m, 5 m or 10 m etc. Two ends of each lamp pipe are provided with a male and a female electrical connecting end respectively. The male and the female electrical connecting ends are provided close to them with a rotation connecting means which rotate to fast connect the lamp pipes. The rotation connecting means can also be used to fast connect a power line, an extension line and an end cap. The fitting light can be fast and conveniently connected without any tool or only with simple tools in operation.
