Abstract

La présente invention concerne un dispositif d'étanchéité de borne et un climatiseur. Une borne (11) se situe sur une première base (12) ; et lorsqu'une seconde base (13) est assemblée à la première base (12), la borne (11) est connectée à un composant se situant sur la seconde base (13). Le dispositif d'étanchéité de borne comprend : un couvercle d'étanchéité (1) placé sur la première base (12), lorsque la première base (12) est détachée de la seconde base (13), le couvercle d'étanchéité (1) servant à étanchéifier la borne (11) ; et une tête de borne (2), une extrémité de la tête de borne étant reliée au couvercle d'étanchéité (1), et l'autre extrémité étant reliée à la première base (12) et servant à fixer le couvercle d'étanchéité (1). Lorsque la première base est détachée de la seconde base, le dispositif d'étanchéité de borne sert à étanchéifier la borne, ce qui permet d'éviter un court-circuitage d'un composant connecté à la borne en raison de la pénétration d'eau dans la borne.
