Abstract: A retaining device comprises a holder for receiving an object and a clamp 4. The holder comprises a cylindrical sleeve 1 with three longitudinal cut-out slits 3 spaced 120° apart and a base 2 secured at one end. The inner surface of the clamp 4 has three lobes 11,12,13 also spaced 120° apart. The portions midway adjacent lobes contact the portions of the sleeve midway adjacent slits 3, resulting in a symmetrical force being applied to the circumference of the sleeve 1 when the clamp 4 is tightened. The clamp 4 is free from the base 2 of the holder and is not rigidly attached to the sleeve 1 and thus does not apply unequal forces to the holder when the clamp is tightened. Alternatively the sleeve 1 may have a thin continuous wall which deforms when forces are applied to it by the clamp 4. The object inserted into the sleeve may have a spherically shaped portion to allow is to be angularly adjusted in the sleeve before the clamp is tightened.

Abstract: A delatch mechanism includes wedges that reside in pockets adjacent to a post on a module when the module is latched in a cage. Pulling on a handle pulls the wedges out of the pockets so that the wedges rise and lift a tab.

The delatch mechanism can include a spring system that returns the wedges to their pockets for latching, allows movement of the wedges relative to the module for lifting of the tab, and locks into the module to pull the module free of the cage. Handles for the latch mechanism can include a bail, a flexible tab, or fixed handle that is part of an integrated structure including the wedges.

Abstract: A fiber optic connector is provided which includes a free floating ferrule so as to reliably withstand significant side-pull forces. In other words, the fiber optic connector is designed such that the minimum rotational angle of the combination of the ferrule and the pin clamp within the connector housing is greater than the maximum rotational angle of the connector housing within an adapter.
