Abstract

L'invention concerne une plaque de renforcement et un dispositif réseau. La plaque de renforcement comprend une carte de circuit imprimé (1) et des connecteurs comprenant une pluralité de broches (2) traversant le trou traversant dans la carte de circuit imprimé (1) ; par conséquent, une première extrémité et une seconde extrémité de chaque connecteur sont formées sur deux côtés de la carte de circuit imprimé (1), les deux extrémités étant utilisées pour se connecter à un dispositif utilisateur. La plaque de renforcement comprend en outre une couche isolante qui comprend une première partie (31) entourant la seconde extrémité, et une seconde partie (32), qui est connectée à la première partie (31) et étanchéifie la partie de connexion entre les deux extrémités et la carte de circuit imprimé (1). La plaque de renforcement et le dispositif réseau emploient une couche isolant pour étanchéifier la partie de connexion entre le connecteur et la carte de circuit imprimé (1), de manière a prévenir les courts-circuits causés par l'entrée d'eau à travers les trous traversants sur la carte de circuit imprimé, évitant ainsi les courts-circuits et l'inflammation de la plaque de renforcement efficacement.
