Circuit board edge clamp for electronic module - uses adjustable wedges cooperating with projecting rib providing guide groove for circuit board edge

摘要

The clamp secures the circuit board edge (23) of an electronic module (12) relative to guide grooves of a module housing (11), defined by a projecting rib (13) on one side and by three spaced wedges. All three of the latter are provided as flat components which, together with the rib, have a thickness of between 1.5 and 2.5 mm, pref. 2 mm. The clamping force is provided by one of the end wedges which can slide in the direction of the opposite end wedge and by the centre wedge which can slide longitudinally and transversely. ADVANTAGE - Simple clamping device with min. number of components.
