Abstract

Dispositif et procédé permettant de déterminer l'établissement réussi du contact dans une connexion et plus précisément dans une prise femelle (21, 25). Ledit dispositif comporte au moins un diviseur de tension (17), des moyens permettant de relever la tension (U) au niveau du diviseur de tension (17), et des moyens (16) permettant d'analyser la variation de la tension (U) dans le temps. Ledit dispositif est caractérisé en ce qu'un condensateur (31, 35) est monté en parallèle avec chaque connexion ou plus précisément chaque prise femelle (21, 25). Pour détecter l'établissement réussi du contact dans une connexion ou plus précisément une prise femelle (21, 25), les moyens d'analyse de la tension (U) détectent une constante temporelle (ζ) avec laquelle la tension (U) chute après désactivation des connexions ou plus précisément des prises femelles (21, 25).
