The invention relates to a constructional system for frames, racks and casings and in particular for sub-racks and equipment cabinets for accommodation of electrical and electronic assemblies, units and printed circuit boards. At least one joint system having engagements is provided for thread-forming screws as fastening elements for particularly cost-effective manufacture of such type of constructional systems, and for simple assembly as well as for ensuring effective EMC screening in accordance with the invention between horizontally and vertically arranged components, in particular between side parts and a top part and a base part having multi-folded horizontal struts and/or vertical struts. Lug joints as second joint zones are preferably provided as an addition to the first joint system having joint zones accessible from the end faces and, third joint zones, for example, for sub-racks or equipment cabinets and which enable, for example, a fixing of printed circuit boards and the like by means of formed, threaded holes.

The invention relates to an insertion and removal aid, particularly for the fitting of electronic subassemblies in systems, with a moulding, which has a locking part and a gripping part, the gripping part being provided with an extension and a substantially complimentary recess for receiving the extension.

Insertion and removal aid

An equipment carrier, e.g. for a monitor or measuring device and having a mounting plate is described, which is tilt-adjustable and lockable in different tilt angles. The equipment carrier comprises a base frame mounted on runners and on which are arranged two columns. A mounting plate is vertically adjustably suspended by means of two oscillating arms between the two columns.

Equipment carrier

A fan slide-in unit, module or chassis of the type used for cooling electronic assemblies. The fan slide-in unit constructed in modular manner having a plurality of fan installation locations arranged in rows and which comprises two half-shells made from substantially acoustically inert material. The number and location of the individual fans can comply with the needs of the particular individual, the installation locations left free being made air-impermeable. The ready electrical connection possibility provided for each installation location permits an easy changeover. In addition, the mounting of the individual fans in the half-shells takes place in solid-borne sound-decoupled manner, so that essentially there is only the noise caused by the air flow. The fans used are controlled in unitary manner by a manually adjustable control block, which can be guided in a temperature or parameter-dependent manner.
