Abstract

L'invention a trait à un mécanisme de connexion (100), comprenant un premier connecteur (10) et un second connecteur (20). Le premier connecteur (10) comprend une première coque (13), un premier corps de distribution de liquide (11) reçu dans la première coque (13) et ayant un premier passage (1130), et un premier élément de repositionnement (15) venant en butée ou se raccordant au premier corps de distribution de liquide (11) et à la première coque (13), respectivement. Le second connecteur (20) comprend une seconde coque (23), un second corps de distribution de liquide (21) reçu dans la seconde coque (23) et ayant un second passage (2130), et un second élément de repositionnement (25) venant en butée ou se raccordant au second corps de distribution de liquide (21) et à la seconde coque (23), respectivement. Lorsque le premier connecteur (10) est séparé du second connecteur (20), le premier corps de distribution de liquide (11) est scellé avec la première coque (13), et le second corps de distribution de liquide (21) est scellé avec la seconde coque (23); et lorsque le second corps de distribution de liquide (21) est inséré dans la première coque (13), le premier passage (1130) du premier corps de distribution de liquide (11) communique avec le second passage (2130) du second corps de distribution de liquide (21). L'invention concerne également un dispositif de distribution de liquide comprenant le mécanisme de connexion (100). Le mécanisme de connexion peut améliorer la commodité de construction et présente une bonne sécurité et une bonne fiabilité.
