Abstract: A fastening system for fastening a plate within an enclosure for electric installations includes an elongated holder and a support member arranged to be fastened to the holder with a snap-in fastening device. The snap-in fastening device is arranged to fasten the support member detachably to the holder in a direction perpendicular relative to the longitudinal direction of the holder and includes a locking device for fastening the support member to the holder at different points along the holder. The snap-in fastening device includes a flexible catch configured to yield in a direction perpendicular relative to the longitudinal direction of the holder, in order to provide adequate support to a plate to be installed within the enclosure. The locking device includes at least one locking element arranged to keep the support member locked in the longitudinal direction of the holder substantially inflexibly.

Abstract: The invention relates to a fastening system for fastening a plate within an enclosure, which enclosure comprises a bottom part (1) and a cover and which fastening system is particularly suitable for fastening a front plate or a contact protective plate (7) within an enclosure for electric installations and comprises an elongated holder (20) to be placed vertically in the bottom part of the enclosure.

Abstract: An electronics and instrumentation enclosure includes a lower portion (4) and a cover (1), which have corner turrets (6 and 3, respectively) provided with through openings (5 and 2, respectively). The cover (1) can be locked to the lower portion (4). Upper locking device includes a locking member (7, 9) having a locking element (19, 20) and lower locking device includes a locking slot (21, 22) for receiving the locking element (19, 20). In a locked position, the locking element (19, 20) is kept in the locking slot (21, 22) by means of a spring element (8). When the lock is in an open position, the cover (1) can be lifted apart from the lower portion (4), whereby a locking member (7, 9) is also detached from a locking ring (16).

Abstract: An enclosure for electric, electronic and pneumatic instruments and devices, the enclosure comprising a box, a cover and hinge means (20) for mounting the cover to the fasteners (3) of the box, which fasteners comprise a support (5) parallel with the wall. The hinge means (20) comprise bearing apertures (11) for hinge pins of the cover and turnable handles (10) for opening and closing the bearing apertures. For the purpose that it would not be possible to open the enclosure without permission from the hinge side without opening the cover at first, the hinge means (20) comprise a body (12), which covers substantially the fastener (3), and an elastic locking tongue (14), which is situated below the fastener support (5) parallel with the wall.

Abstract: The invention relates to an electronics and instrumentation enclosure to be used for electronical, electrical and apparatus installations, preferably for measuring and regulating equipments, which enclosure comprises a lower portion (1'), a frame (2') and a cover (3'), the lower portion comprising fixing points (4') for components to be mounted between the lower portion and the frame. In order to enable versatile component mountings, the frame (2') comprises fixing means (11') for fixing two component mounting plates (7' and 10') on both sides of the frame in such a way that one mounting plate (7') is positioned on the frame side facing the cover (3') and the other mounting plate (10') is positioned on the frame side facing the lower portion (1'). To the frame (2') is preferably connected a hinged cover (3') arranged to cover the frame substantially entirely including screws (5') by which the frame is secured to the lower portion (1'). This solution enables a simple sealing of the enclosure.

Abstract: A printed circuit board clamp, for clamping a printed circuit board to a housing of electronic, electric and apparatus installations, is secured to at least one fixing stud (1) disposed at the bottom of the housing and is provided with a bore (2). The clamp has an elongated body (4) having two ends (6 and 7) and an interconnecting neck portion (8) between the ends. The clamp also has fixing assembly (14-17) for securing the printed circuit board to the clamp. Each of the two ends of the clamp has a throughgoing aperture (9, 10) for screws or the like. At least one of the apertures is elongatedly shaped for securing the clamp to the fixing stud. To substantially facilitate mounting of printed circuit boards within different housings, the clamp includes at least a weakening point (25, 26) that can be broken manually without any tools in order to separate the ends (6, 7) of the clamp from the neck portion.
