Device for supporting printed-circuit boards which can be pushed into a housing

摘要

A device is proposed for supporting printed-circuit boards (which are rigidly connected to one another by means of spacers) in a housing. The supporting device consists of an elastic compensating ring (12) and a compression element (13) which can move with respect to the associated printed-circuit board (1 or 2). The compression element (13) is latched in on the pre-fitted printed-circuit board arrangement by means of an integrally formed latching bolt (18, 19). When the arrangement is pushed into the housing (11), the compression element (13) is moved further towards the elastic compensating ring (12) until a supporting surface (21) of the compression element (13) rests against an inner wall (16 or 17) of the housing (11). As a result of the supporting device (12, 13), the printed-circuit board arrangement is held in its position pushed into the housing (11) without vibration and free of mechanical stresses resulting from manufacturing tolerances and/or different thermal behaviour of the various materials. <IMAGE>
