Abstract
L'invention se rapporte à un appareil électrique encapsulé pour assurer le couplage entre des circuits électriques à sécurité intrinsèque et sans sécurité intrinsèque dans des mines souterraines. L'appareil comporte un organe lumineux qui est disposé, selon l'invention, à la surface du boîtier et qui est relié au circuit se trouvant à l'intérieur par un conducteur mobile. Après disposition de l'organe lumineux sur le boîtier et montage du circuit, le boîtier est rempli d'une résine moulable. L'invention est particulièrement intéressante pour des organes de couplage servant à la commande d'appareils de mines.Disclosed is an encapsulated electrical apparatus for providing coupling between intrinsically safe and non-intrinsically safe electrical circuits in underground mines. The apparatus comprises a luminous member which is arranged, according to the invention, on the surface of the housing and which is connected to the circuit located inside by a movable conductor. After placing the luminous member on the housing and mounting the circuit, the housing is filled with a moldable resin. The invention is particularly advantageous for coupling members serving to control mining devices.
