Electronic coin checker for an automatic vending machine, has a flexible circuit board with electrical connectors to simplify the connecting of a control and evaluation circuit board to electrical test units

摘要

A checker has a housing with a flap attached by a hinge forming a coin inlet channel. The flap contains at least one electrical test unit that is connected via connectors to a circuit board (17) with processing and control elements. The connections are formed on a flexible circuit board (5) and end in solder connection surfaces (12). The flexible circuit board has a positioning unit (11, 14) for fixing it relative to the housing, while the control circuit board also has a positioning unit (18). Solder contacts (19, 12) of the two circuit boards align and are soldered together.
