ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a receiving housing having a framework which has vertical frame sections, a pull-out element secured by a support to at least two of the vertical frame sections, the pull-out element able to be pulled out at the front from the opened receiving housing, an electrical apparatus, for example a central processing unit of a computer, being deposited on the pull-out element, and connection cables being fed to the electrical apparatus.
2. Description of Prior Art
Receiving housings are known wherein connection cables are fed to the electrical apparatus via a pivoting arm mechanism. The pivoting arm mechanism has two arm parts which are connected together via a hinge with a horizontal swivel axis. One of the arm parts is connected to the pull-out element on its end facing away from the hinge. The other arm part is connected to the framework by its free end. The connection cables are fixed to the two arm parts via cable binders. In the starting position when the pull-out element is pushed in, the two arm parts are in a substantially parallel position with respect to each other. When the pull-out element is pulled out, the pivoting arm proceeds into its extended final position where the two arm parts are approximately in alignment to each other. A high parts cost results from this type of cable arrangement. In addition, the pivoting arm requires a pivot region which is then unavailable for fixing components in the interior space of the receiving housing.
SUMMARY OF THE INVENTION
One object of this invention is to provide a receiving housing of the type mentioned initially, wherein the receiving housing has a substantially simplified feeding of the connection cables to the electrical apparatus.
This object is achieved with a power supply chain secured by one of its chain ends to the support and by its other chain end to the pull-out element, and the power supply chain receives the connection cable. Power supply chains are normally used with industrial machines. The different machine assemblies are connected to the power supply chains. According to this invention, power supply chains are suitable for use in switchgear cabinets. The power supply chain needs only a very small space to perform its function and is therefore suitable for use according to this invention.
According to a preferred embodiment of this invention, the support on which the pull-out element is retained has a depth strut which extends in the direction of the housing depth and is secured to the two vertical frame sections associated with the housing side. At least one transverse tie-bar which extends in the direction of the housing breadth is coupled to the depth strut and is disposed in the region of the housing rear side, and to which transverse tie-bar the power supply chain is secured by one of its chain ends. A stable coupling of the pull-out element to the framework is possible with this embodiment of the support. The connection cable can be fed centrally to the pull-out element via the transverse tie-bar.
In particular, the transverse tie-bar extends over the entire housing breadth and at least two pull-out elements, which are disposed side by side and can be operated independently of each other, are secured to the support.
According to another embodiment of this invention, a space-conserving construction is produced when the pull-out element has a plate-shaped depositing portion, on the upper side of which the electrical apparatus is placed and on the lower side of which the power supply chain is secured and guided.
So that the power supply chain can be configured to be relatively short, a receiving housing according to this invention can be configured so that the power supply chain is secured to the region of the pull-out element by one of its chain ends. The region faces the housing rear side, and the other chain end is secured in the region of the housing rear side in a stationary manner.
In order to avoid being crushed, the connection cables should be retained in a controlled manner, away from the guiding elements in which the pull-out elements are displaceable. In order to produce this function, the connection cables have on one of their ends plug-in elements which can be inserted into complementary plug-in receiving means of the electrical apparatus. The connection cables leading from a plug-in side end are pulled into a channel surrounded by the power supply chain via the chain end of the power supply chain which is associated with the pull-out element and are guided out of the channel via the second chain end. The connection cables in the connection to the second chain end are connected to the rear side vertical frame section by means of a cable retainer.
