A patch panel is disclosed which is easily expandable as required by a customer and which substantially simplifies conventional field servicing practices. The invention provides a patch panel comprising an assembly of at least one connector and printed circuit board with the connector being mounted upon the printed circuit board; a mount for removably supporting the assembly of at least one connector and printed circuit board in a desired location relative to the mount and a panel for detachably holding the mount in a predetermined position to the panel such that the panel prevents removal of the assembly of at least one connector and printed circuit board from the mount.

Patch panel

A cabinet with a closure door having a rigid stay for holding the door in an open position. The stay is basically U-shaped and is pivotally held upon a body of the cabinet to be located around hinged together side walls of the body and door in the door open position. As the stay lies up against these side walls, it does not obstruct any access space into the body and it also holds the door with its closure surface directly facing the operator to enable him to maintain equipment upon the door also.

Seals particularly for cable splice closures having two diametrically opposed sealing members. The sealing members are of soft material with a maximum Shore hardness of 15 and preferably a Shore hardness of 10. A sealing rib of each sealing member extends into a cavity to be occupied by the cable with the sealing members assembled together. Each sealing rib bridges axially between a seal base and a rib stiffening element which is spaced axially of the base and inwardly of the radially outer limits of the base. When assembled into a housing with the base of the seal supported by the housing, the rib stiffening element is spaced from the housing. The rib is deflected radially outwards by engagement with a cable and causes outward resilient deflection of the rib stiffening element which provides resilient support for the rib while permitting it to deflect over a wide range of diameters.

Seals

Aerial splice closures with a closure casing of two casing portions and an elastomeric seal at each end of the closure. Each seal has two seal halves with each seal half having an outwardly extending resilient lug which passes through an aperture formed in its casing portion to mount the seal half in the casing portion. Preferably, each lug has a lateral flange which engages the outside surface of the casing portion.

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.
