<p>The invention proposes an assembly that includes a printed circuit board bearing an electrical connector (10) having at least one "signal" contact blade (22a), characterized in that the connector includes at least one protective metal plate (42, 44, 50) that extends opposite a facing portion of the signal blade (22a) and is electrically connected to an "earth" conducting track of the printed circuit board forming part of an earth circuit. The plate forms part of a protective metal cage carried by a pivoting insulating support (60). Thus, any attempt at fraud, with the aim of reaching the signal contact blade (22a) by means of a metal object, results in an electrical connection being established between the protective cage and the signal contact blade, producing a short circuit that is a signal representative of the attempted fraud.</p> |
