VORRICHTUNG ZUR DEMONTAGE EINER LEITERPLATTE

摘要

An arrangement is disclosed for the disassembly from a clock housing of a circuit board which carries various electromechanical and electronic components. The novel disassembly arrangement comprises an ejection device which carries several ejecting posts which can be pushed through corresponding openings in a wall of the housing to press against the circuit board and/or at least a portion of the components fastened to the board, thereby detaching this circuit board from its mounts. The circuit board is held in its position by the frictional force exerted by a contact spring which is designed in the shape of a knife-edge contact so that it will only be necessary to overcome the force of the spring during the ejection operation. The novel disassembly device, made available by the clock manufacturer for use by craftsmen, will make it possible for such person to remove the circuit board and its components rapidly and with very great ease in the case of making necessary repairs.
