ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a cabinet with at least one installed electrical device, which has a front with a front panel with display and control elements and connecting leads from these elements into the interior of the electrical device, as well as a back with mechanisms for the attachment of electrical linking lines.
BACKGROUND INFORMATION
A cabinet is illustrated and described on pages 2 to 4 of Siemens AG Catalog R1.1979, “Electronic Protective Devices.” At least one so-called card cage is installed in this cabinet as the electrical device. The at least one card cage is installed in the cabinet by screwing it to perforated guiding plates of the cabinet. The card cage, as electrical device, has on its front one or more front panels bearing display and control elements. These display and control elements are connected in conventional fashion to the interior of the electrical device via electrical connecting leads. Mechanisms for the attachment of electrical linking lines are present on the back of the electrical device of the cabinet. The mechanisms for the attachment of electrical linking lines function, first, to connect the individual components of the electrical device to one another and, second, to bring linking lines to the outside. The cabinet has a cabinet door not only on its front but also on its back. The cabinet door on the back permits ready access to the mechanisms for the attachment of electrical linking lines. If the cabinet is provided for a particular application in which it is to be set up directly in front of a wall, the card cages are not screwed directly to the cabinet but to a pivoting frame, which permits the electrical device to be pivoted out of the cabinet. After pivoting out, the wiring on the back of the electrical device is readily accessible.
SUMMARY
It is an object of the present invention to develop a cabinet with at least one installed electrical device in such a way that the back of the electrical device is made readily accessible in a manner simple in terms of design.
In a cabinet of the type stated at the outset, this object is achieved according to the present invention by making the front panel of the electrical device removable and mounting the electrical device in the cabinet with the front panel removed and with the back forward. The front panel is held on the cabinet next to the electrical device, and the appropriately long-dimensioned connecting leads are led through the front into the interior of the electrical device.
One advantage of the cabinet according to the present invention is that the use of an electrical device with a removable front panel and appropriately long-dimensioned connecting leads from the front panel into the device interior and the mounting of the electrical device with the back forward result in optimal accessibility of the mechanisms for the attachment of electrical linking lines without the use of a pivoting frame or other costly design approaches. Given an appropriate arrangement of the removed front panel, both the front panel and the mechanism for the attachment of electrical linking lines are simultaneously readily accessible to the operating personnel.
In the cabinet according to the present invention, the front panel of the electrical device can be mounted in various ways. It is possible, for example, to hang or snap in the front panel on a side wall of the cabinet.
It may be advantageous if the front panel is held on a front door of the cabinet or integrated into the front door.
