Switch cabinet layout with one cable entry

Description

[0001] The invention is based on a switch cabinet assembly comprising at least one switch cabinet housing, which has a cable entry on its upper side, which has a guide plate along which at least one cable, conductor, or line with a predetermined radius of curvature is introduced into the switch cabinet housing. Such a switch cabinet assembly is known from Chatsworth: "N-SERIES TERAFRAME RADIUS DROP", October 29, 2020, XP055876921. Similar arrangements are also described in DE 100 07 470 A1, NO 310 010 B1, and DE 198 117 52 C1.

[0002] Conventional cable entries have the disadvantage that they are not suitable for the careful introduction of cables, conductors, wires, and the like into the control cabinet interior. This is due to the fact that the cables, such as electrical conductors, are bent over the top and one edge of the cable entry and inserted into the control cabinet housing, and are inserted in a free-falling manner. Conventional cable entries also do not allow for orderly entry. Instead, the cable entry usually takes the form of a disordered cable bundle.

[0003] It is therefore an object of the invention to further develop a switch cabinet arrangement of the type described at the outset in such a way that it allows, on the one hand, material-saving and, on the other hand, orderly cable entry.

[0004] This object is achieved by a switch cabinet arrangement having the features of claim 1. The dependent claims each relate to advantageous embodiments of the invention.

[0005] Accordingly, the deflector plate is molded onto a width or depth brace of a rectangular horizontal roof frame of a switch cabinet enclosure frame or replaces the width or depth brace. The radius of curvature can be selected, for example, depending on the cross-sections and materials of the inserted conductors, cables, and the like, in such a way that damage to these is effectively prevented.

[0006] With the help of the cable entry, for example, an insertion gap can be created that extends over the entire width or depth of the roof element of the control cabinet housing, so that a large number of conductors can be inserted into the control cabinet housing next to one another and in an orderly manner along the specified radius of curvature, thus protecting the material.

[0007] The at least one cable, the at least one conductor, or the at least one line can be routed along the guide plate from the horizontal to the vertical. The guide plate can, in particular, have a 90° circular segment-shaped guide in the vertical cross-section.

[0008] The guide plate can be designed as a horizontal width brace or a horizontal depth brace. This can extend between opposing profile braces of a frame of the control cabinet housing. Alternatively, the width brace or the depth brace can also replace a profile brace of the frame. For example, the guide plate can be molded onto such a profile brace of the frame.

[0009] The width strut or the depth strut can have fastening means on the fastening flanges facing the opposite profile struts, via which the width strut or the depth strut is hooked into the respective profile strut of the frame.

[0010] The fasteners can engage a system of regularly spaced mounting holes in the profile struts, allowing the mounting position of the guide plate relative to the frame to be varied. This can be used to vary the position of the cable entry and / or to vary the clear opening dimension of the cable entry gap.

[0011] The fastening means may comprise fastening means for pre-positioning the guide plate relative to the frame and fastening means for the force-fitting connection of the guide plate to the frame. The two types of fastening means may be configured as the same fastening means.

[0012] The means for the force-locking connection can comprise an opening in the mounting flange, which is aligned with a preferably geometrically identical opening in the system perforation of the frame. A snap-in connector can be inserted through the aligned openings in the mounting flange and the frame.

[0013] The guide plate can limit an insertion gap of the cable entry with an opposite limiting element.

[0014] The opposite limiting element can be a further guide plate which is aligned mirror-symmetrically to the first guide plate so that cables, conductors or lines can be fed from opposite sides into the insertion gap along a respective curvature of the respective guide plate.

[0015] The additional baffle can be integrally formed onto a roof panel of the control cabinet housing or provided as a folded edge of the roof panel. The folded edge can be designed to face the baffle.

[0016] The guide plate and / or the further guide plate may have a radius of curvature in the vertical plane of at least 0.5 cm and preferably at least 1 cm.

[0017] A brush strip can be attached to a free horizontal edge of the guide plate, which extends in the width direction in the case of a width strut and in the depth direction in the case of a depth strut of the control cabinet housing and which faces an interior of the control cabinet housing.

[0018] A plurality of bristles of the brush strip can extend horizontally. For example, the bristles of the brush strip can extend perpendicular to the insertion direction of a mounting groove of the brush strip, with which the brush strip is attached to a free longitudinal edge of a guide plate.

[0019] A further brush strip can be attached to another guide plate on a roof panel of the control cabinet housing. The two brush strips can be arranged opposite each other with their free ends facing each other and preferably adjacent to each other.

[0020] Further details of the invention are explained with reference to the following figures. Figure 1 shows a perspective top view of an embodiment of a switch cabinet arrangement according to the invention; Figure 2 shows a detail of a perspective top view of a further embodiment of the invention; Figure 3 shows a sectional view of yet another embodiment of a switch cabinet arrangement according to the invention; Figure 4 shows a side view of a switch cabinet arrangement according to the invention; and Figure 5 shows a width strut or depth strut according to an embodiment of the invention.

[0021] The Figure 1illustrates the advantages of switch cabinet arrangements according to the invention over those known from the prior art. The arrangement according to the invention allows the cable entry 2 to be formed across the entire depth of the switch cabinet frame, so that various cables can be inserted side by side in an orderly manner in the depth direction of the switch cabinet housing. Due to the radius of curvature of the guide plates 4, the cable entry is also gentle on the material, so that cable breakage and the like can be effectively avoided.

[0022] In the Figure 1It can also be seen that the guide plates can replace a profile strut of the frame 6 of the switch cabinet housing 1, in the present case opposite depth struts of the roof frame of the frame 1. The cable entries 2 are therefore formed between a roof plate 14 arranged centrally between the guide plates 4 and the two outer guide plates 4. The roof element 14 can also have another molded-on guide plate 4 on each of its opposite edges facing the two outer guide plates 4, for example in the form of a 90° fold with a radius of curvature of, for example, more than 0.5 cm. With the help of these additional guide plates 4 on the roof plate 14, the cable-protecting and orderly cable entry of conductors is possible, which are introduced from an opposite side of the switch cabinet housing 1 over the roof plate 14 into the switch cabinet interior.

[0023] The Figure 2illustrates an embodiment in which the guide plate 4 replaces a depth strut of an upper roof frame of a switch cabinet housing 1, in which the depth strut is fixed via fastening means 8, 9, 10, 11 between opposite width struts of a roof frame of the switch cabinet housing. The fastening means 8, 9, 10, 11 have first fastening means 8, 9 for the positive connection between the flange 7 and the frame 6 and second fastening means 9, 10, 11 for the non-positive connection of the flange 7 to the frame 6. With the aid of the first fastening means 8, 9 for the positive connection, a pre-positioning of the guide plate 4 with respect to the frame 6 is possible in order to establish a non-positive connection with the aid of the second fastening means 10, 11 when the guide plate 4 assumes a desired position, for example with respect to the roof plate 14.

[0024] The roof plate 14 has a limiting element 12 facing the guide plate 4, which is designed as a further guide plate and is arranged mirror-symmetrically to the guide plate 4. From a synopsis of the Figure 3 and 4 It can be seen that with such an arrangement of the guide plate 4 with respect to the limiting element 12 of the roof plate 14, the insertion gap 2 is formed between the guide plate 4 and the limiting element 12 and is defined precisely by the clear opening dimension between the free ends of the guide plate 4 and the limiting element 12. In the manner known from the prior art, brush strips 16 can be provided to prevent dust from entering the interior of the switch cabinet, which brush strips close the inlet 2 in a conductor-permeable manner.

[0025] With reference to Figure 4It can be seen that the brush strips have a vertical insertion groove and bristles extending perpendicular to the insertion direction of the groove, whereby a brush strip 16 can be attached to both the guide plate 4 and the limiting element 12, in particular to their horizontal free edges. Alternatively, however, it is also conceivable for a brush strip to be attached to only one of the two free edges mentioned, which closes the entire horizontal clear opening of the cable entry 2.

[0026] The Figure 5shows an exemplary embodiment of a guide plate 4, which can be designed as a simple sheet metal part. In particular, the guide plate 4 can be formed from a central, curved sheet metal piece, which only has a flange 7 on each of its opposite end faces for attaching the guide plate to the frame of the control cabinet housing. The radius of curvature should be at least 0.5 cm to enable particularly gentle cable entry. The radius of curvature is particularly preferably more than 1 cm.
