Injector/ejector latch lock mechanism

摘要

A latch/ejector mechanism (2), designed for use with components (6) such as power supplies, computer modules and circuit boards, is used to secure a component to and release the component from a housing (104) by engaging and disengaging a catch element (96) on the housing. The mechanism includes a handle (8) pivotally mounted to the component for moving between latched and unlatched positions. The handle has a latch (94) at one end (28) which engages with and disengages from the catch element during such pivotal movement of the handle. The mechanism also includes a trigger (10) which must be actuated to permit the handle to be moved from the latched position to the unlatched position. A security lock (12), movable between locked and unlocked positions, is used to prevent the actuation of the trigger. In the locked position the lock surface (86) of the security lock opposes a portion of the trigger, called a prevent element (90). However, moving the lock to the unlocked position causes the lock surface of the security lock to be misaligned with the prevent element to permit unimpeded movement of the trigger element thus permitting actuation of the trigger element to release the handle.
