Abstract

L'invention concerne un ensemble (10) protégé contre les explosions permettant le blindage d'au moins un composant électrique et/ou électronique (11), lequel est disposé sur une surface porteuse (12) d'un support (13). L'ensemble (10) protégé contre les explosions permet une protection contre les explosions grâce à un blindage résistant à la pression et/ou à un enrobage. Au moins une chambre de réception (18) pour le ou les composants (11) est ménagée dans un corps de recouvrement (17). La chambre de réception (18) est entourée sur sa périphérie par une surface de contact (26) qui se trouve dans le prolongement (21) de l'ouverture (21) de la chambre de réception (18). La surface de contact (26) peut être disposée par exemple sur un rebord (25) périphérique. L'ensemble (10) comprend un élément d'accouplement élastique (30) disposé entre la surface de contact (26) du corps de recouvrement (17) et la surface porteuse (12) du support (13). Une liaison détachable, à force et/ou par coopération de formes est établie entre le corps de recouvrement (17) et le support (13) à l'aide d'un dispositif de liaison par enfichage et/ou d'un dispositif de liaison par encliquetage (43). Lorsque la liaison est établie, l'élément d'accouplement élastique (30) est déformé élastiquement et produit une force d'accouplement (K) entre la surface de contact (26) et la surface porteuse (12). De cette manière, une étanchéité fiable de l'espace de réception (18) ou du point de liaison entre le corps de recouvrement (17) et le support (13), permettant d'obtenir la protection contre des explosions, est garantie.
