Abstract

La présente divulgation concerne un détendeur électronique. Une borne positive d'un ensemble bobine est électriquement connectée à une carte d'adaptateur, et est électriquement connectée à une broche positive dans la carte d'adaptateur. De plus, une borne négative de l'ensemble bobine est électriquement connectée à la carte d'adaptateur, et est électriquement connectée à une broche négative dans la carte d'adaptateur. Par conséquent, lorsque les positions de la borne positive et de la borne négative de l'ensemble bobine changent, les positions de connexion de la borne positive et de la borne négative sur la carte d'adaptateur peuvent donc changer, tout en maintenant une connexion électrique avec la broche positive et la broche négative, de sorte que les positions de connexion de la broche positive et de la broche négative sur la carte de circuit imprimé n'ont pas besoin d'être modifiées. Par conséquent, le détendeur électronique présente l'avantage d'une compatibilité élevée et peut être compatible avec des ensembles de bobines de différentes structures.
