Description

The present invention relates to a marking device for cabinets and other electrical equipment and for plant construction.

In the prior art a variety of labeling devices for control cabinets have become known to affix identification plates for precise identification of cabinets. A disadvantage of the known labeling devices that the identification plates must have exactly defined dimensions in the rule, since the support and support surfaces are precisely matched to the respectively provided identification plates. In addition, it may happen in the known labeling devices that the labels are wrongly used during assembly incorrectly when z. B. during assembly erroneously pushed the one side of a label under the intended support surface. Then the assembly must be repeated or there is a risk of loss in case of non-notice.

From the document DE 198 47 540 A1 a label carrier for receiving a label of thin sheet material is known. This label carrier has a closed up to its narrow sides receiving slot for the label, wherein the receiving shaft is bounded by a bottom wall and a transparent top wall and two longitudinal sides. In this case protrude from the inner surface of the bottom wall, two deformable Andrückzungen obliquely into the receiving shaft, wherein the upper wall facing edge surfaces of Andrückzungen the label against the Press inside of the top wall. In the undeformed state of the label carrier thus the clear distance between the inside of the top wall and the Andrückzungen is less than the sheet thickness of the male label. In order to still be able to insert the label made of thin sheet material, it is sufficient to bend the label carrier about its longitudinal axis, whereby the clear distance increases and insertion of the label is made possible. Since insertion of the label is only possible via the openings in the narrow sides of the receiving shaft, the upper wall arranged above the pressing tongues prevents the label from being inserted underneath the pressing tongues.

However, this type of Untersteckschutzes is not possible with label carriers with a carrier profile that has no closed on a top wall receiving shaft.

It is therefore an object of the present invention to provide an identification device for control cabinets and other electrical devices, which also better with a carrier profile that has no closed on a top wall receiving shaft, miscarriage of a label is avoided.
