Entrance terminal housing having walls sealed together at their junctions and defining a chamber opening. A removable cover is provided for the opening and a seal between walls and cover. In preferred arrangements, removable covers isolate terminals within the housing from other terminals and also isolate the terminals from the rest of the chamber. A fire resistant conductor sleeve is provided of flexible material and is of radially expansible and collapsible tapered tubular form for sealing around a range of numbers of conductors passing through a wall of the housing. In one construction, the sleeve has axially extending corrugations which allow for its expansion and collapse.

Entrance terminals for telecommunications cable

In an entrance terminal for a telephone cable, each terminal has an integral cable conductor trough at one side, generally closed by a cover. End walls in the troughs have apertures therein the apertures breaking through the edges of the end walls of the troughs, forming gaps of a width less than the diameter of the apertures. Sleeves extend through the appertures in adjacent end walls of adjacent terminals. By axially sliding a sleeve upward, out of the apertures, it is possible to remove a terminal without disturbing the remainder, as conductors can be eased through the gaps.
