The invention relates to an insert element for

Frameworks, in particular racks, for use in information and network technology, comprising a plurality of slots. The invention further relates to a cable storage element for insertion into an insertion location of the insertion element.

In information and network technology, it is often necessary to stow a large number of network components and computers within a rack and connect them to one another via cables, in particular network cables. In data center operations, but also in event, laboratory and control technology, the term rack stands for a frame for electrical devices with a standardized width of 19 inches, in which the individual devices (so-called. Slide-in elements) that can be mounted in the rack have a front panel width of exactly 48.26 cm (19). The slide-in elements are fastened with four screws each in the rows of holes in vertical sheet metal angles near the front edges of the rack.

The cabling of the individual slide-in elements with one another is complex. If cables with standard cable lengths are used, there is the problem that there is often an excess length, which results in a great deal of disorder, which also leads to a

Confusion and difficult manageability caused when plugging the various cables of the network system.

The present invention therefore aims to avoid the aforementioned disadvantages.

To solve this problem, the slide-in element according to the invention for frame racks, in particular racks, for use in information and network technology, comprises a plurality of slide-in locations, the slide-in locations receiving slide-in cable storage elements in each of which a cable is received, The two cable ends of which are guided to the outside via openings formed on the end face of the cable storage element and can be pulled out of the cable storage element in a variable length. This ensures orderly and space-saving storage of the cables within the rack and a variability in terms of the length of the cable connections required in each case. Because both cable ends can be routed out at the end of the cable storage element with variable length, the required cable length can be pulled out of the cable storage so that both the connection between two insert elements or components that are close to one another and between insert elements inserted further away from one another in the rack or.

Components is possible. Disturbing excess cable lengths are avoided.

It is particularly advantageous if the two cable ends can be pulled out of the cable store independently of one another.

The slide-in element according to the invention is preferably developed in such a way that the two cable ends can each be pulled out of the cable storage element independently of one another against a spring force. If only one of the cable ends has to be repositioned within the rack, this is possible without the connections at the other cable end

to solve. This helps to avoid complicated plugging and rearranging of the cable connections. In particular, this avoids having to swap a cable of a defined length for a shorter or longer cable.

Advantageously, the inventive

Slide-in element further developed in that the cable in the cable storage element is guided around a roller fastened to a spring element and is guided around a deflection element at the end opposite the spring element. The spring element is the

Cable storage element recorded cables held on train.

The cable to be picked up is guided around the roller attached to the spring element and due to the spring element, the roller can be moved by pulling on the respective cable ends within the cable storage element in the direction of the end face of the cable storage element and is released by means of the spring force exerted on the roller by the spring element the cable connection is also pulled back into the cable storage element. The spring element can be designed, for example, as a helical spring, torsion spring, spiral spring, for example a spiral leaf spring or the like. Furthermore, the cable received in the cable storage element is guided around a deflection element on the end face of the cable storage element. By routing the cable twice around the pulley and the deflection element, a large amount of cable can be accommodated in a comparatively small storage element and the spring element enables one or both cable ends to be pulled out and in again in a variable manner.

The slide-in element according to the invention can in particular be developed in such a way that the deflection element is designed as an element that is fixed in the longitudinal direction, in particular as a fixed roller. The deflecting element thus fulfills a double function. On the one hand, it is used to deflect the cable to be accommodated in the cable storage element - i.e. to guide it around the deflection element and, on the other hand, the upper and lower end of the cable, respectively, above and below. lead out below the deflecting element from the cable storage element. The deflecting element is preferably rotatably mounted.

The slide-in element according to the invention is preferably developed in such a way that the cable storage element comprises a housing enclosing a cuboid storage space and the cable is received in the storage space. Due to the fact that both the slide-in element and the cable storage element are cuboid-shaped, a storage option for the respective cables that is extremely space-saving and at the same time makes the best possible use of the space within the slide-in element is created.

Advantageously, the inventive

Slide-in element developed to the effect that the slide-in element has a height of 1.75 inches and a width of 19 inches. These dimensions correspond to the slide-in locations available in a commercially available rack, which enables the slide-in elements provided according to the invention to be accommodated in existing racks without problems.

The slide-in element according to the invention does not therefore require any specially made racks.

The depth of the slide-in element can be selected variably and depending on the length of the cable to be stowed. For example, depths of 40cm, 60cm, 100cm and 120cm are conceivable.

The slide-in element according to the invention can in particular be developed in such a way that the slide-in element has at least 3, preferably 5 to 48, in particular 24, slide-in positions. It depends on the thickness or length of the cable to be accommodated. In the case of thin, short cables, the cable storage element can be designed to be less wide and deep, which means that an insert element can also have a larger number of insertion locations. With thicker, longer cables, wider cable storage elements are required, which in turn

Requires slide-in elements that have fewer slide-in slots. Furthermore, a combination of slide-in locations of different widths within one slide-in element is also conceivable.

The slide-in element according to the invention is preferably developed in such a way that the roller fastened to the spring element has a separating element arranged in the middle of the roller. The separating element acts as a separating wall between the cable sections guided around the roller. This enables the cable ends to be pulled in and out without problems, since the different cable sections cannot overlap due to the separating element.

Advantageously, the inventive

Slide-in element developed to the effect that means are provided for braking the return movement of the roller.

Furthermore, the slide-in element according to the invention can in particular be developed in such a way that the roller interacts in a dragging manner with the housing wall of the storage space of the cable storage element. The height of the separating element can for example be chosen so that the achieved diameter of the roller is only slightly below the height of the housing of the cable storage element, whereby the roller slowly runs back when one of the cable ends is released due to the spring force and thus prevents uncontrolled and jerky pulling in of the cable becomes.

Furthermore, it can preferably be provided that the

Cable storage element comprises a roller system with several, in particular two, resiliently held rollers. This makes it easier to pull out the two resiliently held rollers together with the cables surrounding them independently of one another.

That according to the invention is particularly preferred

Slide-in element developed in such a way that a partition is attached between each two resiliently held rollers of the roller system. The slide-in element according to the invention is preferably developed in such a way that the partition divides the storage space into two chambers and the first resiliently held roller is guided in the first chamber and the second resiliently held roller is guided in the second chamber.

This enables the respective roller to move without disruption without being hindered by the other roller in each case.

The slide-in element according to the invention can in particular be developed in such a way that the cable is a ribbon cable, in particular a coaxial cable or a twisted pair cable or a round cable. The cable can also be a network cable, an audio cable or a telephone cable.

Advantageously, the inventive

Slide-in element developed in such a way that the cable storage element can accommodate up to 2.4 m of cable. The inclusion of 2.4 m of cable is particularly possible with a cable storage element with a depth of 60 cm. Similarly, a cable storage element with a depth of 30 cm can accommodate 1.2 m of cable, a cable storage element with a depth of 100 cm can accommodate 4 m of cable and a cable storage element with a depth of 120 cm can accommodate 4.8 m of cable.

The invention further relates to a cable storage element for insertion into a slot of a slide-in element, which comprises an elongated housing enclosing a cuboid storage space, a cable being received in the storage space, the two cable ends of which are led outwards through openings formed on the end face of the cable storage element and are variable in length the

Cable storage element can be pulled out.

Preferred developments of the cable storage element emerge from the subclaims and have already been discussed in connection with the slide-in element according to the invention. .

The invention is explained in more detail below with reference to the exemplary embodiments shown schematically in the drawing

In this Fig.l shows the slide-in element according to the invention, FIG. 2 shows a first embodiment of the cable storage element according to the present invention, FIG. 3 shows a plan view according to the first embodiment of the cable storage element from FIG. 2 and FIG. 4 shows a second embodiment of the cable storage element according to the present invention Invention.

Fig.l shows a slide-in element 1 for frame racks, which has 24 slide-in locations 2 arranged next to one another for receiving slide-in locations 2 which can be pushed into the slide-in locations 2

Having cable storage elements. The single ones

Insertion locations are separated from one another by separating elements, in particular separating webs, running in the longitudinal direction. The insert element has a cuboid housing with a preferred height a of 1.75 inches and a preferred width b of 19 inches. The cable storage elements are pushed in the direction of the arrow 3 into the slide-in positions 2 of the slide-in element 1 and fixed in the slide-in element 1 by snapping the clips 4 into place at the head-side end of the cable storage element. The insert element 1 can be screwed to the frame by means of the connecting elements 5 attached laterally to both sides of the insert element 1.

FIG. 2 shows a first embodiment of a cable storage element 6 according to the invention, which can be pushed into the insert element shown in FIG. The cable storage element 6 has a cuboid housing 15, the width and height of which essentially correspond to the width and height of the slots 2. The housing accommodates a cable 7, the two cable ends 8, 9 of which extend over to the end face 10 of the cable storage element 6

9/26

9 * formed openings (not shown here) are guided outward in the direction of arrow 11 and can be pulled out of the cable storage element 6 in a variable-length manner.

It would be conceivable, for example, that the openings on both sides taper and that the cables can be clamped and thus fixed in the laterally narrower areas of the openings after they have been pulled out.

It can also be seen from Fig. 2 that the

Cable storage element 6, a spring element 12, one on

Spring element 12 has a fixed roller 13 and a roller-shaped deflection element 14. The im

Cable 7 accommodated in the cable storage element 6 is guided around the roller 13 fastened to the spring element 12 and further guided around the deflecting element 14 at the end opposite the spring element 12. The cable 7 is here inserted into the cuboid housing 15 on the end face 10 of the cable storage element 6, guided in the direction of the roller 13, passed around the roller 13 for the first time and deflected by 180 °. Following this, the cable 7 is returned to the end face 10 of the cable storage element 6, where it is guided around the deflection element 14, deflected again by 180 ° and then guided a second time in the direction of the roller 13. There the cable 7 is passed around the roller 13 one more time, deflected by 180 ° and returned again to the end face 10 of the cable storage element 6, where it leaves the cuboid housing 15.

By pulling on the two cable ends 8, 9 according to arrow 11, the cable ends 8, 9 can each be independent of one another

10/26 lü .. 'can be pulled out of the cable storage element 6 against the spring force exerted by the spring element 12.

The cable 7 is thus led around both the roller 13 and the deflecting element 14, which enables twice the amount of cable 7 to be accommodated in the cable storage element 6.

Furthermore, it would be conceivable for the cable to be guided more than twice around the roller 13 and the deflection element 14, which enables longer cables 7 to be stowed in the cable storage element 6.

3 shows a plan view according to the first

Embodiment of the cable storage element 6 from FIG. 2. The roller 13 attached to the spring element 12 has a separating element 16 arranged in the middle of the roller 13, which firstly serves to guide the cable 7 in an orderly manner even after the roller 13 has been wrapped and secondly acts as a means for braking the return movement of the roller 13, since the height of the separating element 16 is selected such that the separating element interacts in a dragging manner with the housing wall 15 of the storage space of the cable storage element 6.

In FIG. 4 it is shown on the basis of a further embodiment of the present invention that the insert element 6 can comprise a roller system with two resiliently held rollers 17, 18. Here, a partition is attached between the two resiliently held rollers 17, 18 of the roller system. The partition 19 divides the storage space into two chambers, the first resiliently held roller being guided in the first chamber and the second resiliently held roller 18 being guided in the second chamber.
