L'invention concerne un procédé de configuration d'interface, un dispositif terminal et une interface pour améliorer le problème d'une broche CC d'une interface de type c dans un dispositif terminal qui est corrodé. Dans le procédé, un module de traitement dans un dispositif terminal configure, lorsqu'il est déterminé qu'un connecteur de type c n'est pas connecté à un dispositif externe, une puce PD devant être dans un premier état de fonctionnement dans lequel une broche CC délivre en continu un niveau bas, et configure, lorsque le module de traitement surveille que le connecteur de type c est connecté à un dispositif externe au moyen d'un module de surveillance, la puce PD Se trouve dans un second état de fonctionnement dans lequel la broche CC délivre une onde carrée de niveau élevé, de telle sorte que la puce PD identifie le dispositif externe, assurant ainsi le fonctionnement normal d'une interface de type-c. Selon la solution, lorsqu'un connecteur de type c n'est pas connecté à un dispositif externe, une broche CC peut être activée pour délivrer en continu un niveau bas, ce qui permet de réduire considérablement la différence de tension Entre la broche CC et une broche GND et d'atténuer davantage la corrosion de la broche CC après qu'une interface de type c soit affectée par l'humidité ou soit immergée dans un liquide.
