A pressure relief body sintered from a wire mesh and retained on an explosion-proof housing by welding. The corresponding welded seam has a fusion zone both on the pressure relief body and on the housing part and makes a mechanically robust and gas-tight joint between the two.
A housing arrangement comprising a housing an inner space for accommodating components capable of forming sources of ignition. The housing arrangement further comprises a partial housing arranged in or on the housing and the interior space. The interior space acts as a pressure relief volume. The interior space and the pressure relief volume are connected together via a passage in which a gas-permeable and flame-arresting arrangement is provided. This can be formed from a porous body, for instance, which is gas permeable and acts in a throttling and cooling manner on a gas flow passing through it.
A housing with an inner lining, made of an open-pore material, preferably covering at least two sides of the housing, for the reduction of internal explosion pressure. In addition, or alternatively, a molded body made of the open-pore material, for example a bonded fibrous material, may be arranged in the housing.
The invention relates to an explosion-proof housing (10) having external walls (11), which enclose a housing interior (12) so as to be proof against ignition penetration relative to an atmosphere at risk of explosion. At least one insert (15) is arranged in at least one outer wall (11). The insert (15) facilitates a gas flow between the housing interior (12) and an environment (13) around the housing (10). The at least one insert (15) is configured in such a way that a gas flow having a sufficient mass flow or volumetric flow rate is permitted, but a flow connection which is proof against ignition penetration is produced. Attached to the outer wall (11) having the at least one insert (15) is a guiding means (27) which together with the relevant outer wall (11) delimits a flow channel (28). The flow channel (28) defines a main flow direction (R) of a main gas flow (G) through the flow channel (28) substantially parallel to the directly adjoining outer wall (11). In this way, the gas exchange between the environment (13) and the housing interior (12) can be improved and facilities (14) arranged in the housing interior (12) can be cooled.

METHOD FOR PRODUCING AN EXPLOSION-PROOF LINE BUSHING, AND EXPLOSION-PROOF LINE BUSHING
The invention relates to a method for producing an explosion-proof line bushing (10) and a line bushing (10) of this kind. A prespecified quantity or mass of elastomeric material is applied to a line (11), which quantity or mass of elastomeric material completely surrounds the line (11) in a flat section (24) in the circumferential direction. The line (11) comprising the elastomeric material (22) is inserted into a passage opening (30) of a bushing body (15). The bushing body (15) is preferably plastically deformed over its entire axial length. After the plastic deformation, the elastomeric material (22) substantially completely fills the volume remaining between the formed bushing body (15) and line (11). The elastomeric material (22) is elastically deformed and presses both against the line (11) and also against the formed bushing body (15), so that flame-proof gaps (34) are formed between the bushing body (15) and the line (11). The applied mass of the elastomeric material (22) is determined and prespecified depending on the inner volume between the formed bushing body (15) and the line (11) remaining after the forming of the bushing body (15). Therefore, the mass of the elastomeric material (22) depends at least on the external dimensions of the line (11). Bushing bodies (15) with the same dimensions can therefore be used for lines (11) with different external dimensions.

While the first section (17) is free and contains at least one light source, an operating circuit (25) for the light source (19) and/or other components forming potential ignition sources and/or other components that are not considered as ignition sources are arranged in the section section (18). The section (18) is provided with an open-pore filling material. The separating wall (16) has at least one opening (22) which permits a fluidic connection between the two sections (17, 18). The section (18) of the internal space (15) provided with filling material (29) functions as a pressure-relief volume for the first section (17), in which the light source (19) is arranged. The filling material (29) can entirely or partially fill the section (18).
The invention relates to a housing arrangement (10) comprising an inner space (16) for accommodating components (13, 14, 15) which can form sources of ignition. The housing arrangement (10) further comprises a part housing (12) which is arranged in or on the housing (11) and the interior space (17) of which acts as a pressure relief volume (22). The two interior spaces (16, 17) are connected together via a passage (18) in which a gas-permeable and flame-arresting arrangement (19) is provided. This can be formed from a porous body (20), for instance, which is gas permeable and acts in a throttling and cooling manner on a gas flow passing through it.

The invention relates to a plug-in device which has a blocking sleeve, which divides the plug-in operation between the plug and the socket into two path sections. In a first path section, before the electrical contact is established, explosion-proof encapsulation of the plug and the socket is brought about. The plug and the socket are initially temporarily locked in this position and further insertion is blocked. Further insertion is not enabled until the sleeve is rotated relative to the socket housing (11) and the plug housing (12). Once this has occurred, the second path section can be run through, in which the electrical contact is established. Thereafter, by further rotation of the blocking sleeve, the plug and the socket are locked in the coupled state by means of the blocking gate (23), which blocking gate is effective between the blocking sleeve (22) and the socket housing (11) and between the blocking sleeve and the plug housing (12). Uncoupling occurs in the opposite direction, wherein, because the course of the blocking groove (24) and/or (26) is bent at least twice, the plug and the socket are securely temporarily locked against each other in such a way that an explosion-proof intermediate space is formed, the electrical contacts already being disconnected in this state.

EXPLOSION-PROOF ARRANGEMENT FOR PASSAGE OF A BOLT AND METHOD FOR PRODUCING SAME
The invention relates to an explosion-proof arrangement (22) comprising an electrically conductive bolt (23) which is composed of a rigid material which is not deformable in the radial direction. The bolt (23) is coaxially enclosed by an electrically insulating, elastically deformable sleeve (30) in a central section (23a). The sleeve (30) is in turn coaxially surrounded by a connecting section (41) of a plastically deformable connecting body (40). Plastic deformation of the connecting section (41) reduces the outside dimensions of said connecting section and said connecting section presses inward against the sleeve (30) which is supported on the bolt (23). This results in a force-fitting and optionally additionally interlocking connection which forms a structural unit comprising the connecting body (40), the sleeve (30) and the bolt (23). When the structural unit is produced, a first stop face (26) which is provided on the bolt (23) obliquely or radially in relation to the longitudinal axis (L) of the bolt (23) bears against a correspondingly associated first mating stop face of the sleeve (30). In addition, a second stop face can be provided on the sleeve (30), said second stop face being oriented obliquely or radially in relation to the longitudinal axis (L), and an associated second mating stop face (46) of the connecting body (40) bearing against said second stop face.
The invention relates to an explosion-proof assembly (20) which is designed to guide at least one line device (21) through a wall without the break-through of a flame. The assembly (20) has at least one guide-through part (24) with one or multiple guide-through openings, each of which is delimited in the circumferential direction by a guide-through surface. The at least one guide-through part (24) is designed to be arranged in the wall. A connecting element (23) is assigned to each line device (21) and coaxially surrounds the line device (21) in an attachment section by forming an spark gap-free connection. The connecting element (23) has a first boundary surface. The guide-through surface represents a second boundary surface. A flame-proof Ex gap (34) is formed between the two boundary surfaces by the at least partial insertion of the connecting element (23) into the guide-through opening. The guide-through openings of the guide-through part (24), in which no connecting element (23) is arranged without a spark gap, are sealed in a flame-proof manner by a sealing means (70). A securing device (52) secures the connecting elements (23) in the guide-through opening (48).

The invention relates to an explosion-proof arrangement (20). The arrangement (20) has a feed-through part (23) having a feed-through opening (24), which is limited by a feed-through surface (25). A structural unit (29) is arranged in the feed-through opening (24). The structural unit (29) has a deformable inner body (31) having at least one line channel (32) that in a longitudinal direction (L) completely passes therethrough, said line channel being enclosed by a plastically deformable connection sleeve (30) in a circumferential direction (U) around the longitudinal direction (L). At least one conductor (22) of a line (21) is led through an assigned line channel (32) in the inner body (31). A connecting portion (33) of the connection sleeve (30) is plastically deformed so that it presses radially inwards onto the inner body (31), thus deforming the same in a radial direction (R) radially to the longitudinal direction (L). On the plastically deformed connecting portion (33), a first boundary surface (35) is formed on the outer circumference. The lead-through surface (25) forms a second boundary surface (36). By arranging the structural unit (29) with the first boundary surface (35) in the lead-through opening (24), an ignition spark resistant ex-gap (37) is created between the two boundary surfaces (35, 36).

The invention relates to an assembly (14) of a cable-connecting device (10) and a multi-core cable (11), which form a mechanical, explosion-proof connection to each other. For this purpose, the cable-connecting device (10) has a plastically deformable outer sleeve (18) having a crimping section (23). A hollow cylindrical inner sleeve (19) made of elastically deformable material is arranged between a cable sheath (13) made of elastomer and the crimping section (23). An elastic deformation of the inner sleeve (19) and of the cable sheath (13) is caused by radially plastically deforming the crimping section (23). Any gaps (40) present within the cable sheath (13) are closed due to the radial forces in the crimping section (23) such that spark-gap-free contact between the cable sheath (13) and the cores (12) of the cable (11) and between the cable sheath (13) and the inner sleeve (19) is ensured.

DEVICE FOR LEADING A PART INTO AN EXPLOSION-PROOF HOUSING IN A DUST IGNITION-PROOF MANNER
Disclosed is a device (10) for leading a part (90) through an opening (21) in a wall (20) of an explosion-protected housing (15) in a dust ignition-proof manner. In one embodiment, an elastically deformable and/or malleable sealing member (49) is arranged directly in the opening (21) in the wall. A clamping arrangement (59) is used for clamping said sealing member (40) against a clamping portion (29) of the wall (20), said clamping portion (29) tapering transversely to a lead-through direction (D). In order to clamp the sealing member (40), the clamping arrangement (59) applies an axial clamping force on the sealing member (40) in the lead-through direction (D). During this process, the sealing member (40) can be at least slightly deformed in a radial direction and comes to rests against the opening (21) in the wall and against the part (90) that is led through the sealing member (40), resulting in a dust ignition-proof arrangement.
A feedthrough device (10) for an explosion-proof housing constructed as a “flameproof enclosure” of the flame protection type. The feedthrough device (10) is arranged in a wall opening of the housing and forms a flameproof gap therein. A rigid component (11) is arranged through said gap to be displaced in its direction of extension relative to the wall. The feedthrough device (10) has a clamping body unit (20), a sleeve (21), a cap (22) and a thrust collar (23). The sleeve (21) and the cap (22) can be screwed together. Axial forces are transmitted between the clamping body unit (20) and the cap (22) via the thrust collar (23). The sleeve (21) exerts a radial clamping force on the clamping body unit (20), which is fully penetrated by a conduit (25) along a longitudinal axis (L), in which conduit a longitudinal section of a component (11) is arranged.

The invention relates to an explosion-proof assembly (10) for encapsulating at least one electrical and/or electronic component (11) that is arranged on a carrier surface (12) of a carrier (13). The explosion-proof assembly (10) achieves the explosion protection in accordance with a pressure-resistant encapsulation and/or a potting encapsulation. At least one accommodating chamber (18) for the at least one component (11) is present in a covering body (17). The accommodating chamber (18) is surrounded by a circumferential contact surface (26), which adjoins the opening (21) of the accommodating chamber (18). The contact surface (26) can be present, for example, on a circumferential flange (25). The assembly (10) has an elastic coupling element (30), which is arranged between the contact surface (26) of the covering body (17) and the carrier surface (12) of the carrier (13). A releasable force-closed and/or form-closed connection is established between the covering body (17) and the carrier (13) by means of a plug connection device and/or detent connection device (43). When the connection has been established, the elastic coupling element (30) is elastically deformed and causes a coupling force (K) between the contact surface (26) and the carrier surface (12). Reliable sealing of the accommodating chamber (18) or rather of the joint between the covering body (17) and the carrier (13) is thereby ensured in order to achieve the explosion protection.
