The invention relates to a housing (1) for an electrical operating means such as a light, plug-in device, measuring instrument, switch, distributor, or the like, having at least one first and one second housing part (2, 3) that can be assembled with one another in an explosion-proof fashion. Each housing part has one joining surface (4, 5); when the housing parts are assembled, said joining surfaces are in contact with one another, forming a penetration-proof gap (6). In order to provide a novel structure of joining surfaces by means of which a corresponding penetration-proof gap is formed independently of the cross-sectional shape of the housing parts and to be able to substantially unite the advantages of both joining surfaces and the housing mentioned above, the joining surfaces run substantially perpendicular relative to the rest of the housing parts and surface profiles (7, 8) are formed in said joining surfaces, the penetration-proof gap being formed between said surface profiles.
L'invention concerne un boîtier (1) pour un matériel électrique de type luminaire, dispositif de prise, instrument de mesure, interrupteur, distributeur ou similaire, qui présente au moins une première et une deuxième partie de boîtier (2, 3) pouvant s'assembler l'une avec l'autre de manière antidéflagrante. Chaque partie de boîtier présente une surface de contact (4, 5) venant buter l'une contre l'autre lorsque les parties de boîtier sont assemblées l'une avec l'autre pour former une fente (6) résistante au claquage. Afin de préparer une nouvelle structuration des surfaces de contact permettant de former une fente résistante au claquage correspondante de construction simple, indépendamment de la forme de la coupe transversale des parties du boîtier, et afin de pouvoir réunir essentiellement les avantages des deux surfaces de contact susmentionnées et ceux du boîtier, les surfaces de contact sont essentiellement à la verticale des parties de boîtier restantes qui logent des profils de surface (7, 8) entre lesquels se forme la fente résistante au claquage.
