摘要： A pressure relief device for an explosion-proof housing. The pressure relief device has a lamellae arrangement having a plurality of lamellae. The lamellae are arranged in a transverse direction with distance to one another and thereby limit flow channel between two lamellae respectively. Each flow channel establishes a flow connection between a first opening and a second opening of the lamellae arrangement that are arranged with distance to one another in flow direction. Each flow channel has a non-straight preferably meandering or wave-shaped extension between the first opening and the second opening and can be flameproof as an option. Water drops that accumulate inside the flow channel are retained due to the contact with the two adjacent lamellae due to adhesion forces. In doing so, the pressure relief device is configured as protection against throughflow of water without additional measures.

摘要： The invention relates to an explosion-proof arrangement (10) with an explosion-proof housing (11) which has a wall opening (23) in a housing wall (12). The wall thickness (d) of the housing wall (12) is so small that it is not possible to form a thread there in order to screw in a connecting body (15) for a line to pass through or for receiving an assembly so as to ensure protection against flame transmission. According to the invention, a connecting body (25), which has a flange (38) with a flange face (39), is inserted into the wall opening (23). The flange face (39) delimits a flameproof gap (58) by way of the housing wall (12). The dimensions of a gap or intermediate space between the connecting body (25) and a boundary face (24) of the housing wall (12), which boundary face delimits the wall opening (23), are not important. The protection against flame transmission can be provided solely by the flameproof gap (58) between the flange face (39) and the housing wall (12).

摘要： The luminaire according to the invention comprises an inner space that is separated into a first section and a second section by a separating wall. While the first section is free and comprises at least one light source, an operating circuit for the light source and/or other components that form potential ignition sources and/or other components that may not be considered as ignition sources are arranged in the second section. The second section is provided with an open pored fill material. The separating wall comprises at least one opening that allows a flow connection between the two sections. The section of the inner space provided with fill material serves as pressure relief volume for the first section, in which the light source is arranged. The fill material can fill the section completely or partly.

摘要： An explosion-proof line bushing and method for producing the line bushing. A prespecified amount of elastomeric material is applied to a line and completely surrounds the line in a flat section in the circumferential direction. The line is inserted into a passage opening of a bushing body. The bushing body is preferably plastically deformed. After the plastic deformation, the elastomeric material substantially fills the volume remaining between the formed bushing body and line. The elastomeric material is elastically deformed and presses both against the line and the formed bushing body, so that flame-proof gaps are formed between the bushing body and the line. The applied mass of the elastomeric material is determined depending on the inner volume between the formed bushing body and the line remaining.

摘要： A housing (10) which has a first part (14) with a first wall (22) having an outer wall surface (28) and a second part (18) with a second wall (24) having an inner wall surface (30). The wall surfaces can have for example a cylindrical casing shape at least in some sections. Portions of the first wall (22) and the second wall (24) overlap in an overlap region (26). The first wall (22) and the second wall (24) are connected along the circumference of the wall surfaces (28, 30) by means of a rotational friction welding seam (32) arranged in the overlap region (26). The rotational friction welding seam (32) has a compact zone (48) with a first elastic modulus and a mixing zone (44) with a different second elastic modulus.

摘要： An explosion-proof assembly (20) is provided for guiding at least one conductor device (21) through a wall without ignition transmission. The assembly (20) has at least one bushing part (24) arranged in the wall having one or more bushing openings, each of which is delimited in the circumferential direction by a bushing surface. A connecting body (23) is associated with each conductor device (21) coaxially surrounds a mounting portion of the conductor device (21) in a flamegap-free connection. The connecting body (23) has a first outer delimiting surface and the bushing opening defines a second delimiting surface. A flameproof Ex gap (34) is formed between the two delimiting surfaces by at least partial insertion of the connecting body (23) into the bushing opening. Bushing openings without a connecting body (23) are closed in a flameproof manner by a closure member (70). A securing device (52) secures the connecting body (23) in the bushing opening (48).

摘要： An electrical device has a plug-in connection device (15), which is used to open and close an electrical circuit (24). The plug-in connection device (15) contains at least two contact/mating-contact pairs (22, 23), which have different ignition protection types. At least one of the two contact/mating-contact pairs is designed to interrupt the current running through said contact/mating-contact pair without triggering an explosion. (Ignition protection type Ex d or Ex i.) The other contact/mating-contact pair (23) opens and closes in the currentless state. Therefore, the other contact/mating-contact pair can have a second ignition protection type, such as Ex e.

摘要： The invention relates to a holding apparatus (10) for a housing (11) and method for affixing the holding apparatus (10) and the housing (11) to an affixation surface, in particular an external building surface. The holding apparatus (10) has two holding parts (12) that each have a holding segment (25) that extends in a longitudinal direction (L). At least one of the two holding parts (12) additionally has a locking segment (43). Two attachment parts (46) and, for each locking segment (43), one locking part (47) are affixed to a rear wall (11b) of the housing (11). To mount the housing (11) on the holding apparatus (10), the two attachment parts (46) are firstly each brought into engagement with their respective holding segment (25). By displacing the housing (11) in the longitudinal direction (L), the locking part (47) enters into engagement with the locking segment (43). A continued movement of the housing (11) in the longitudinal direction (L) is at least delimited.
