<p><P>PROBLEM TO BE SOLVED: To provide an assembly including a printed circuit board for supporting an electric connector 10 equipped with at least one "signal" contact blade 22a. <P>SOLUTION: In this assembly, the connector has one or more metal protection plates 42, 44 and 50; and the metal protection plates are extended so as to face a facing part of a signal blade and electrically connected to a "grounding" conductive track of the printed circuit board forming a part of a grounding circuit. The plates form a part of a protection metal cage supported by a pivot motion insulation support. Thereby, electric contact is generated between the protection cage and the signal contact blade by a trial of fraud for reaching the signal contact blade by using a metal object and a short circuit being signal expression of the tried fraud is produced. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
