Telecommunication cable aerial closure

An aerial terminal for telecommunication wires is preferably blow-molded, and includes a closure for the in-line splices to a cable and a housing for the drop wire connectors can be mounted together, with the housing mounted on the side of the splice closure so both the interior of the closure and the drop wire connectors are readily accessible from one side.

Aerial terminal

A cable closure end cap arrangement is provided, to achieve a sealing between a cable splice closure, and a cable end in communication therewith. The arrangements according to the invention may be adapted to accommodate more than one cable extending into an end of a cable closure. Preferred arrangements comprise a composite of inner and outer members, each having a bore therein. Each bore is preferably defined by an arrangement of concentric rings, or a circular ridge/trough arrangement. The circular rings include transverse walls extending therebetween, in a preferred manner permitting an accordion-like flexibility. The accordion-like rings accommodate; cables of different sizes; cables at various angles relative to the end cap arrangement and the cable closure; and, movement of the cable closure, for example upon an aerial messenger wire. End cap arrangements according to the present invention are mounted by means of a slit in communication with each bore. The slits are preferably prepared by cutting slots formed in the end cap arrangement during manufacture. Preferred end cap arrangements are made from a rubber, or thermoplastic rubber material, for flexibility and long life.

Cable closure end cap

A fiber optic splice closure for protecting the splice made into a transmission cable, containing a plurality of fibers which are to remain unsevered, comprises a base to which the cable is anchored and in which slack fibers in the uncut cable are looped and stored free of transverse barriers. The seal is made with the cables and the base by a mating cover provided with a second area to receive splice trays and slack fibers selected from the cable for splicing.
