摘要： An explosion-proof enclosure includes a front cover (first housing half or portion) and a rear cover (second housing half or portion) joined together by a retention member inserted into a passageway at least partially formed by structures of both the front cover and the rear cover. The enclosure includes an internal chamber for containing an associated electronic device. The passageway generally extends peripherally about the internal chamber. In one exemplary embodiment, the retention member is a ball-chain and the passageway completely surrounds the internal chamber such that respective end portions of the ball-chain overlap. A sealing element is provided for sealing respective mating surfaces of the front cover and rear cover. In another example, the retention member is a rigid split retention member.

摘要： A loudspeaker arrangement may include a loudspeaker having first and second voice coils to provide motive force for a loudspeaker membrane, and an electric transformer having a primary coil connectable electrically to an electrical power unit, and a secondary coil connectable electrically to the first and second voice coils. The voice coils each may have two first winding ends connected to each other via a first electrical conducting path to form a parallel electrical circuit and two second winding ends connected to each other via a second electrical conducting path. The first electrical conducting path may be connected electrically to a first winding end of the secondary coil via a first electrical connecting path and via an additional first electrical connecting path, which may form a parallel circuit with the first electrical connecting path. The second electrical conducting path may be connected electrically to a second winding end of the secondary coil via a second electrical connecting path and via an additional second electrical connecting path, which may form a parallel circuit with the second electrical connecting path.

摘要： An electronic circuit arrangement may include first and second electric connections connectable to first and second electronic devices, respectively. A first electric conduction path may connect the first and second electric connections, and a second electric conduction path may connect a tee point provided in the first electric conduction path to an electric ground connection. First and second switching elements may be provided in the first and second electric conduction paths, respectively, between the tee point and the respective electric connection. Each switching element may switch between an open state, in which the switching element may interrupt the respective electric conduction path, and a closed state. In response to connecting the second electronic device to the second electronic connection, the second switching element may switch to the open state, and the first switching element to the closed state only after the second switching element is already in the open state.

摘要： A housing for receiving an electrically operated apparatus may include an inner housing part at least partially defining a housing interior. The inner housing part may include an inner passage opening. The housing may also include an outer housing part disposed on a side of the inner housing part facing away from the housing interior. The outer housing part may include an outer passage opening. The outer passage opening and the inner passage opening may at least partially define an acoustic duct for discharging airborne noise from the housing interior. The acoustic duct may be closed by a fluid-tight and airborne noise-permeable membrane. Further, the housing may include a porous member disposed within the acoustic duct configured to prevent an ignition breakthrough from the housing interior into an external environment outside of the outer housing part.

摘要： A device assembly for accommodating an electrically operated device may include a housing made from a plastic, delimiting a housing interior space, and having a viewing window formed therein that may be closed by a window pane made of a transparent material. The device may include an electrically operated device arranged inside the housing interior space, on the outside of which at least one actuatable control element may be provided. An aperture may be formed in a housing wall in which an actuating element made from an elastic plastic may be arranged at least partially and may be operable by a user of the electrically operated device. The actuating element may be coupled mechanically to the control element such that the control element is operable from outside the housing. An inner housing part made from an elastic plastic may be arranged on an inner side of the housing wall.
