Abstract

L'invention porte sur un composant de surface à aimant permanent. Il comprend un premier support et un aimant permanent. Il existe une rainure dans le premier support, et l'aimant permanent est fixé dans la rainure. L'aimant permanent a une surface aimantée d'une manière aimantée sur une seule face et à pôles multiples. La surface aimantée est renfoncée, formant une rainure magnétique. L'invention porte également sur un système de connexion magnétique utilisant le composant de surface à aimant permanent. Le système comprend au moins une unité d'adsorption, chaque unité d'adsorption comprenant un composant de surface attiré par l'aimant et le composant de surface à aimant permanent. Le composant de surface à aimant permanent a un dispositif d'aimantation, et le dispositif d'aimantation est attiré par l'aimant permanent du composant de surface à aimant permanent. Le composant de surface attiré par l'aimant et le composant de surface à aimant permanent dans le système de connexion magnétique sont combinés à l'unité d'adsorption par la force magnétique mutuelle. Le composant de surface attiré par l'aimant et le composant de surface à aimant permanent peuvent être scindé ou combiné de façon facultative. L'aimant permanent du composant de surface à aimant permanent à aimantation d'une manière d'un seul côté et à multiple pôles, ne créera pas d'interférence avec des dispositifs électroniques périphériques et est très sûr.
