Abstract: An electronic plug-in module to be accommodated in a mounting rack with a module rail in the front region comprises a circuit board, a circuit board holder and an adapter. The adapter features a receptacle for a mounting element in order to mount the adapter on the module rail. The circuit board holder is fixed on the circuit board in the front corner region of the circuit board. It features a coupling structure that is coupled to a corresponding coupling element of the adapter in order to produce a coupling between the circuit board holder and the adapter. In an end position of the plug-in module in the mounting rack, the adapter and the circuit board holder cooperate in such a way that the plug-in module is held in its position in the mounting rack.

Abstract: On a module carrier for digital communications technology modules, a guidance and support element for incoming and outgoing optical wave guides is arranged that is formed of two pieces, an LWL guidance and an LWL support element. An adjustable connector accomplishes the connection of both elements, whereby their position with each other is permitted to change.

Abstract: A cabinet for the acceptance of electrical and electronic components includes a rack to which a door leaf 8 having a hinge 2 as well as wall elements are mounted in a detachable fashion, the hinge 2 having at least one stationary section 3 attached to a side rail 1 of the rack as well as at least one pivoting section 4 attached to the door leaf 8. The cabinet is improved in such a fashion that the pivot axis 13 of the hinge 2 is disposed in the vicinity of the outer side of the door 14. A cabinet is thereby created whose wall elements can not be accessed from the outside whose attachment elements in the vicinity of the hinge 2 are advantageously easily accessible by opening the cabinet door even when the cabinet is fully equipped and without having to remove its contents.

Abstract: A switch cabinet for electronics and electrical engineering is proposed with a door hinged on at least one side (1) as well as a centering mechanism for the level centering of the door during closing (1), where the centering mechanism is arranged in the area of the locking mechanism, and where the centering mechanism's components, one centering piece (3) and one catching part (11), are arranged on the door (1) or on a framework element (2) of the switch cabinet and interlock when closing the door (1).

Abstract: The invention deals with an electronics cabinet with a shelving frame of sectional rails 8 on which casings 2,3 are attached. On the insides 19 of the casings 2,3, longitudinal grooves 38 are designed in which contact springs 24 lock into. The contact ridges 27 of these contact springs 24 lie at each neighboring sectional rail 8 when the casings 2,3 are attached.

Abstract: A corner joint element 1 for longitudinal bars 7 and cross bars 8 that are created from hollow profiles 10 of a rack has three legs 2, 3 and 4, which are standing at right angles to each other. The surface of each leg 2, 3, 4 has at least one cavity 11. For the fastening of a hollow profile 10, slipped onto a leg 2, 3, 4, the wall area 12 of the hollow profile positioned above the cavity 11 is pushed into the cavity 11.

Abstract: The discovery concerns a fastening device for hinge parts and wall elements on frames of equipment enclosures in the electronic industry, whose sectional side rails show a longitudinal groove. A sprung u-clip 13 showing two thread carriers 16,23, is attachable in this longitudinal groove. A spring tongue 20 on the u-clip faces outward and reaches into a mounting on the longitudinal groove. The longitudinal groove bears rows of through holes corresponding to the thread carrier 16,23 for attachment screws.

Abstract: A rack for an equipment cabinet comprises a rectangular base plate, an identically constructed roof plate and four profiled pillars. For the fastening of the profiled pillars, various fastening means are provided at the base plate and the roof plate. Three groups of four fastening holes each serve as fastening means at the corners of the base plate and the roof plate, as well as respectively three sections of four pairs of stop lugs each, which are allocated to the fastening holes in a definite manner. A fastening bore is provided in each profiled pillar, and the profile of each profiled pillar is provided with at least one profiled rib which, when the profiled pillars are positioned and screwed in, is disposed in a gap between a pair of stop lugs.
