Abstract: A latching device is provided for a circuit pack having a cable retainer carried upon the front of the operating lever of the device. The cable retainer is oriented for positional and directional control of cable by directing cable longitudinally of the faceplate of the circuit pack and away from the fronts of other circuit packs within a shelf.

Abstract: A latching device is provided for a circuit pack having a cable retainer carried upon the front of the operating lever of the device. The cable retainer is oriented for positional and directional control of cable by directing cable longitudinally of the faceplate of the circuit pack and away from the fronts of other circuit packs within a shelf. Also provided is a combination of a latching device and two groups of covers. The combination enables a single latching device to be used upon circuit packs requiring security and non security conditions within a shelf. It also enables removal of a faceplate held to a faceplate mounting with the circuit pack in the shelf. An orifice in an operating lever of the device is accessible with a cover of the first group mounted upon the operating lever, as orifices in these covers align themselves with the orifice in the operating lever.

Abstract: A printed circuit board with a face plate having a connector support located behind it and being movable for access to the connector support. The connector support has a connector mounting for connecting two fiber connectors, the geometry being such that with the face plate removed, the rearwardly directed connector and accompanying fiber is accessible together with the forwardly directed fiber and connector for cleaning purposes without removal of the circuit board from operational position within a shelf.

Abstract: Electrical connector having a latch to hold it to a support in working position. Included is a pivoted handle which normally lies close to the connector body, but which is accessible to allow it to be moved to a position for gripping to allow for connector removal from the support. The handle is connected to the latch so that as the handle moves to the position for connector removal, it automatically disconnects the latch thereby permitting withdrawal of the connector. Useful for connector positioning in confined spaces and allows for narrower circuit pack designs while also including essential latch mechanisms which, because of the narrow designs, are manually inaccessible.
