Ratchet mechanism engagement element retaining device uses wedge moved into retaining position for locking engagement element in ratchet position e.g. for locking component housing to circuit board

摘要

The device secures the engagement element (1) of the ratchet mechanism, e.g. a hook, for preventing its movement from the ratchet position, via a retaining wedge (2), moved into a retaining position in which it is clamped between the engagement element and a rigid counter-surface (3). The retaining wedge is moved into the retaining position by movement perpendicular to the ratchet movement of the engagement element and has at least one wedge surface (5) at an acute angle to the perpendicular movement.
