Description

Rahmenprofϊl

The invention relates to a frame profile for a frame of a rack or a control cabinet or a table or a table arrangement and a frame or a control cabinet or a table or a table arrangement with such a frame profile.

Such a frame profile is designed to build a frame for a rack or a control cabinet or a table arrangement with structures or attachments, in particular as an open or closed hollow profile to achieve the required load-bearing capacity, and is provided with openings and / or webs to provide a variety of installation options inside the control cabinet to offer and to achieve the required sealing against climatic or electromagnetic interference on the outside of a control cabinet using sealing strips. The frame profiles can also be designed for tightly lining up frame frames constructed therefrom. Reference is made to DE 33 44 598 A1, DE 44 39 551 A1 and DE 1 96 47 814 A1 as examples of such frame profiles and frame frames constructed therefrom. From one of the Like frame or switch cabinet or a table arrangement, various types of electrical devices, for example information technology devices, are often added, the power supply being carried out via cables which are laid in the frame or switch cabinet and guided by means of corresponding holding elements or, in particular in the case of higher power requirements, also current collecting rails.

The invention has for its object to provide a frame profile and a frame that gives improved installation options with reduced installation effort.

This object is achieved with the features of claim 1. According to this, it is provided that the frame profile consists of a support profile and a power supply received by it with a plurality of busbars embedded in an insulation and running in the longitudinal direction of the support profile and accessible along a long side.

With these measures, the frame profile is used in addition to its carrying properties as a holder and guide for simple, clear electrification, which results in simple, clear connection options and e.g. a simple data transmission option is also obtained.

A space-saving and at the same time secure accommodation, which can also be easily designed as a protection against contact, consists in the insulation and the busbars being introduced into a receiving chamber which is at least partially open on a longitudinal side of the profile. A simple structure, in which the power supply can also be used subsequently, results from the fact that the insulation is designed as at least one insulating profile with the longitudinal side which is at least partially open over the busbar.

A simple structure with simple contacting options and contact rails which can be accommodated in a contact-protected manner are achieved in that longitudinal grooves are formed in the insulation into which the busbars are introduced.

An advantageous embodiment for simple handling and simple construction is that the insulating profile has a rectangular cross section.

A favorable accommodation of the power supply is obtained in that the receiving chamber has a rectangular or square basic cross-section and that the insulation consists of two sections which are arranged on the two side walls directed perpendicular to the opening side of the receiving chamber and each carry at least one busbar. The accommodation and the contacting are favored in that the busbars of the two subsections are opposite each other in a plane parallel to the opening side.

A favorable arrangement also results from the fact that, for inserting the sections formed in each case as an insulating profile, partial chambers are formed on the two side walls with a base web formed by a section of the respective side wall and limiting webs perpendicular thereto, or that the two insulating profiles are plugged onto retaining webs protruding from the two side walls.

The functional capability of the frame profile is expanded in that the frame profile has at least one row of fastening holes, at least one fastening longitudinal groove and / or at least one fastening web in at least one profile side that adjoins the opening side of the receiving chamber parallel or at right angles. The mounting holes, longitudinal grooves and / or mounting webs are arranged on a built-in frame or control cabinet or a table arrangement or a table on the inside of the frame or control cabinet and offer simple installation options with easy access to the electrification system.

The possibility of using the frame profile, in particular for a control cabinet, is further favored by the fact that a free space is formed in an edge region remote from the opening side by means of an obliquely running wall section and / or sealing edges projecting vertically outwards.

For the precautions for electrification, the measure can furthermore prove to be advantageous in that at least one earthing bar is inserted in the clear opening area of the receiving chamber.

The installation or connection options of a frame or switch cabinet or on a table arrangement are expanded in that the frame or switch cabinet with at least one frame leg in the form a frame profile is provided. For example, at least one vertical profile is advantageously designed as such a frame profile. The receiving chamber is advantageously on the inside of the cabinet or frame or the lateral vertical profiles of a table.

The connection of built-in devices or other electrical devices, such as IT devices, to the power supply becomes simple in that adapters that can be inserted into the receiving chamber and can be fixed to the power supply are provided for contacting.

If it is provided that two adapters are connected to one another to form a baying adapter arrangement, the power supply can advantageously also be provided in an adjacent cabinet or frame or table system, connection to a power supply only being required in a control cabinet or frame or on a table.

Various inexpensive connection options for the power supply to the power supply consist in the power supply being connected or connectable to a power supply via an end face inserted into the frame profile or via an adapter.

Furthermore, at least one horizontal frame profile can additionally or alternatively be provided with a power supply of the type mentioned. Simple coupling pieces can be used for electrical coupling between vertical and horizontal frame profiles. The invention is explained in more detail below using exemplary embodiments with reference to the drawings. Show it:

5 shows an adapter for connecting to a power supply according to FIGS. 1 to 3 and

Fig. 6 shows a table arrangement with vertical and horizontal frame profiles with power supply.

A frame profile 10 shown in FIG. 1 is designed as a multi-chamber profile, with sealing elements directed outwards at right angles to build up a frame. edges 12 and in an outer edge region, a free space 13 is formed with a sloping profile wall, while an open receiving chamber 11 is provided for the interior of a frame 1 to be built (see FIGS. 2 and 3). In the receiving chamber 1 1, a power supply 20 with opposing insulating profiles 22 and embedded therein, accessible along a long side busbars 21 is inserted.

The receiving space 1 1 accessible from an opening side 14 has an approximately rectangular or square basic shape, which in the present case is somewhat bulged on the side opposite the opening side 14. The side walls perpendicular to the opening side 14 are designed as partial receptacles for the two insulating profiles 22, with respective side wall sections forming a base web 1 1.1 and limiting webs 1 1 .2, 1 1 .3 formed thereon and projecting at right angles to form a lateral limitation of the partial receptacles.

The insulating profiles 22 used in the partial receptacles, for example during the manufacturing process or later, have a substantially rectangular cross section, with at least one, in the present case for example two, longitudinal grooves being formed in each of their inner sides facing one another, in which the strip-like, for example, also rectangular in cross section Busbars 21 are introduced. The busbars 21 lie in the depth of the longitudinal grooves 22.1 of the insulating profile 22, the lateral groove walls protruding to such an extent that protection against contact with fingers is reliably ensured. The longitudinal opening arranged in a first inner side 14 of the profile, which corresponds to the opening side of the profile, is at least on one side of the opening edges facing one another with an inserted earthing bar 23 in Form a copper bar, so that a simple ground connection is obtained.

The frame profile 10 is advantageously used as at least one vertical frame leg of the frame 1, which is connected with suitable corner connectors or by simple screwing with a cover frame and floor frame formed from horizontal frame legs in width and depth 10 'or 10 ", as shown in FIG 2 and 3. In the frame profile 10 with the power supply 20 shown in FIGS. 2 and 3, longitudinal T-grooves for fastening internals or are provided in the two inner sides 14, 15 of the profile inner sides 14, 15 which are perpendicular to one another and adjoin the receiving chamber 11 Cross struts are arranged, it being possible, for example, to insert threaded strips with rows of threaded bores into the T-grooves 16, 17. Alternatively, the frame profile 10, similar to the two horizontal frame legs 10 ', 10 ", can also be provided with rows of fastening holes.

The electrical devices installed at any point in the frame, such as control units or servers, can be easily connected by means of an adapter 40 adapted to the power supply 20 or the insulating profiles 22 with the inserted busbars 21, as shown in FIG. 5. The block-shaped adapter 40 is designed, for example, in such a way that when it is aligned it is introduced longitudinally to the opening of the receiving chamber 11 and is then contacted with the busbars 21 by rotation through 90 °. Contacts 41 of the adapter 40 can also be spring-mounted, for example, in order to generate the required contact force. The longitudinal grooves 22.1 with the inserted busbars 21 of the mutually partial insulating profiles 22 lie in the opening side or the corresponding one Profile inner side 14 parallel planes, wherein a pair of busbars 21, for example, a conventional DC voltage and another pair of busbars 21 provide an AC voltage or other DC voltage or serve as a line for data transmission. The power supply 20 can also be connected to a supply voltage by means of a suitable adapter 40 or from the lower or also the upper end face. For a series of such frame frames, adapters 40 to be used can be connected to one another in the frame profiles 10 lying next to one another, so that only a connection to a voltage supply is required.

If desired, as an alternative or in addition, at least one horizontal frame leg 10 ′, 10 ″ can be formed from a frame profile 10 with a power supply 20. Frame legs formed by folding can also be provided with a power supply in the manner described on a side wall of a control cabinet.

Since at least the vertical frame legs are provided with a free space 13 on their outside, they can easily be fitted with accessories, such as hinge or locking elements 30 or with side walls, the edges of which protrude into the free space 1 3 and the inside of which is close to the sealing edges 1 2 concern, be connected.

Fig. 6 shows a table arrangement or a table system 30 with tables 31, which have vertical frame legs designed as support columns, which are arranged protruding up to the height of the table tops or beyond and can be provided with additional shelves. The vertical frame legs that are preferably arranged on the narrow sides of the table tops, are preferably substantially flat, at least on their mutually facing inner sides, and are at least partially designed from frame profiles with current guides 20 accessible from the inner sides in accordance with the above statements. In addition to the longitudinal access openings of the respective power supply lines 20, a plurality of rows of fastening receptacles arranged in the longitudinal direction are preferably provided for attaching horizontal frame legs, for example by means of hooks and / or screw connections. The horizontal frame legs can also be equipped with current leads 20 of the aforementioned type from frame profiles. An electrical coupling between the power supply lines 20 of the vertical and the horizontal frame legs can be carried out by means of adapted coupling pieces which are provided with contacting means on sides lying at right angles to one another. It is sufficient if the connection to a supply is made on only one vertical or horizontal frame leg, from which the current can then be passed on to other frame legs by means of coupling pieces.
