Protective structure for securing hardware against break-in, has contact between elastomer and circuit board interrupted when attempt is made to remove circuit board

摘要

The protective structure comprises an elastomer (4) in connection with two circuit boards (1,2). The conductor traces of the elastomer and the circuit boards, and the contacts between elastomer and circuit board are not adaptable from outside. The two circuit boards are releasably connected to the elastomer. An attempt to remove a circuit board from the elastomer causes an interruption of at least one of the contacts between the elastomer and the circuit board.
