Description
Distribution device The invention relates to a distribution device for information technology and telecommunications, in particular to an optical waveguide distribution device, as claimed in the precharacterizing clause of claim 1.
Distribution devices are used in distribution cabinets for optical waveguide cables, such as those from the product catalog "Zubehor ffir LWL-Kabelnetze, [Accessories for optical waveguide cable networks]
issue 2, page 227, year 2002, Corning Cable Systems GmbH & Co. KG". The optical waveguide distribution device disclosed there is used in particular for handling optical waveguides which have been prefabricated with plugs, such as patch cords or pigtails, with the optical waveguide distribution device disclosed there having a distribution panel which is mounted in a housing like a drawer. The distribution panel of the distribution device disclosed there has guide elements for the optical waveguides, couplings for the plugs of the prefabricated optical waveguides, strain relief devices for optical waveguide cables to be inserted into the distribution panel, as well as receptacles for splices of optical waveguides which have been spliced to one another, in which case all of the elements or components mentioned above are in the form of individual parts and ~re connected to a mount element in the distribution panel. The optical waveguide distribution device, and therefore the distribution panel in it, can be attached via the housing to a rack for example in a distribution cabinet, with the housing having attachment sections at an angle to it, via which the housing of the optical waveguide distribution device can be screwed to the rack in the distribution cabinet. This governs the position of the optical waveguide distribution device in the distribution cabinet.
Against this background, the present invention is based on the problem of providing a novel distribution device.
The problem on which the invention is based is solved by a distribution device having the features of claim 1. According to the invention, a holding element acts in the area of in each case two mutually opposite side walls of the distribution panel, with guide sections of the holding elements being guided on the side walls of the distribution panel such that the distribution panel can be moved in the sense of a drawer-like relative movement with respect to the holding elements, in which case the distribution device can be mounted via angled attachment sections of the holding elements on a rack in particular in a distribution cabinet, and in which case at least one stud-like projection is formed in the area of each of the mutually opposite side walls of the distribution panel and can in each case be latched or snapped into in each case one of a plurality of recesses, which are integrated in the guide sections on the holding elements, in order to lock a different relative position between the distribution panel and the holding elements.
One stud-like projection, which is mounted in a sprung form, is preferably arranged in the area of each of the two mutually opposite side walls, in which case each stud-like projection has a circular or oval base area, and in which case each stud-like projection is curved at right angles to the direction of the relative movement between the distribution panel and the holding elements such that a guide section of a holding element can be moved over it, like a ramp.
A plurality of differently contoured recesses are preferably integrated in the guide section of each wo 2007/009592 - 3 - PCT/EP2006/006539 holding element and allow and/or prevent movement over a stud-like projection depending on their contouring and, possibly, depending on the direction of a relative movement between the distribution panel and the holding elements.
Preferred developments of the invention are specified in the dependent claims and in the following description. Exemplary embodiments will be explained in more detail with reference to the drawing, in which:
Figure 1 shows a perspective view of a distribution device within the meaning of the invention, comprising a distribution panel and holding elements arranged on both sides of it;
Figure 2 shows a perspective view of a detail of the distribution device shown in Figure 1, in the area of a holding element and a side wall of the distribution panel;
Figures 3a to 3c show the detail from Figure 2 in three different relative positions between the holding element and the side wall of the distribution panel;
Figures 4a and 4b show a further detail of the distribution device from Figure 1, in the area of one side wall of the distribution panel;
Figure 5 shows an alternative detail to the detail in Figure 4;
Figure 6 shows a further alternative detail to the detail in Figure 4; and Figures 7a to 7d show various refinements and views of a stud which is arranged in the area of one side wall of the distribution panel and interacts with a holding element.
The invention will be described in the following text using the example of a distribution device in the form of an optical waveguide distribution device. Although the use of the invention is preferable for optical waveguide distribution devices such as these, the invention is not restricted to optical waveguide distribution devices. In fact, the invention can also be used for other distribution devices for information technology and telecommunications, for example for distribution devices for copper cables or else for hybrid distribution devices in which optical waveguide cables and copper cables are placed and/or handled jointly.
Figure 1 shows a perspective plan view of one exemplary embodiment of an optical waveguide distribution device 10, with the optical waveguide distribution device 10 having a distribution panel 11 which can be mounted like a drawer via holding elements 12 on a rack in a distribution cabinet. In the illustrated example, the distribution panel 11 has a bottom wall 13 as well as four side walls 14, 15, 16 and 17, with the side wall 14 forming a front wall of the distribution panel 11, and the side wall 15 forming a rear wall of the distribution panel 11. The holding elements 12 act on the side walls 16 and 17 of the distribution panel 11, with a translational relative movement being possible between the distribution panel 11 and the holding elements 12, in order to move it like a drawer.
As can be seen from Figure 1, recesses or openings 18 are integrated in that side wall 14 of the distribution panel 11 which is in the form of a front wall, into which recesses or openings 18 couplings, which are not illustrated, can be inserted or latched, for plugs which are not illustrated. It should be noted that couplings such as these may also be an integral component of the front wall of the distribution panel.
The distribution panel 11 for the optical waveguide distribution device 10 illustrated in Figure 1 is used primarily for handling and as a repository for splices which are formed between optical waveguides which have been prefabricated with plugs at one end and optical waveguides which have been inserted via an optical waveguide cable into the distribution panel 11. Optical waveguides which have been prefabricated at one end with plugs are also referred to as pigtails.
The splices between the prefabricated optical waveguides and the optical waveguides which have been inserted via an optical waveguide cable into the distribution panel 11 are held in receptacles 19 for the splices, with the receptacles 19 being an integral component of the distribution panel 11, which is in the form of a plastic injection-molded part.
Those ends without plugs of the optical waveguides which have been prefabricated with plugs at one end can be passed to the receptacles 19 via guide elements 20 while ensuring that minimum bending radii are maintained for the optical waveguides. Those ends of the prefabricated optical waveguides which have been prefabricated with plugs can iikewise be passed to the couplings, which are not illustrated, for the plugs via guides 21 which are arranged adjacent to the front wall 14 of the distribution panel 11, while complying with minimum permissible bending radii, with the couplings which are not illustrated being accommodated in the openings 18 in the front wall 14. Further guide elements 22 for the prefabricated optical waveguides are positioned between the guide elements 20 and 21 and form an excess-length storage means 23 for the prefabricated optical waveguides.
At least one optical waveguide cable with optical waveguides guided in it can be inserted into the distribution panel 11 of the optical waveguide distribution device 10 illustrated in Figure 1, specifically through an opening 24 which is integrated in the rear wall 15 of the distribution panel 11. For strain relief for the optical waveguide cables which have been inserted into the distribution panel 11, the distribution panel 11 has strain relief devices 25 for the optical waveguide cables, wherein optical waveguides which have been inserted via the respective optical waveguide cable into the distribution panel 11 can be passed via guide elements 26 to the receptacles 19 for the splices while complying with the minimum permissible bending radii for the optical waveguides.
Further guide elements 27 for the optical waveguides which have been inserted via an optical waveguide cable into the distribution panel 11 form an excess-length storage means 28 therefor.
The receptacles 19 for splices between the prefabricated optical waveguides and the optical waveguides which have been inserted via an optical waveguide cable into the distribution panel 11 are an integral component of the distribution panel 11, which is in the form of a plastic injection-molded part, in the same way as the guide elements 20, 21, 22, 26 and 27 as well as the strain relief devices 25.
As already mentioned, the distribution panel 11 can be attached to a rack, preferably in a distribution cabinet, via holding elements 12 which act on the side walls 16 and 17 thereof, and can be moved backwards and forwards translationally with respect to the holding elements 12, in the form of a drawer-like relative movement. As can be seen in particular in Figures 1 and 2, the holding elements 12 have guide sections 29 which act on the side walls 16 and 17 of the distribution panel 11, and/or are guided on them.
Furthermore, the holding elements 12 have attachment sections 30 which are at an angle to the guide sections 29 and via which the optical waveguide distribution device 10 can be attached to a rack, in particular in a distribution cabinet.
When an optical waveguide distribution device 10 is attached to a rack in a distribution cabinet, the position of the holding elements 12 is fixed, but the distribution panel 11 can be moved translationally with respect to the holding elements 12, specifically in the form of a drawer-like relative movement. Fiaures 3a, 3b and 3c show different relative positions between a fixed holding element 12 and a side wall 16 or 17 of the distribution panel 11 in the optical waveguide distribution device 10 according to the invention, with the distribution panel 10 having been moved to the left with respect to the holding element 12 in Figure 3a, and with the distribution panel 11 having been moved to the right with respect to the holding element 12 in Figure 3b. In the position shown in Figure 3a, the distribution panel 11 is withdrawn, for example in order to form splices on optical waveguides which have been placed in the distribution panel 11, with respect to a rack to which it is attached via the holding elements 12. In contrast, in Figure 3b, the distribution panel 11 has been pushed back into the rack, to be precise beyond the position illustrated in Figure 3c, in order in this way, for example, to protect plugs acting on the front wall 14 of the distribution panel 11 against mechanical stresses.
A stud-like projection 31 is formed in the area of each of the side walls 16 and 17 of the distribution panel 11. The stud-like projections 31 interact with recesses within the holding elements 12 in order to lock different relative positions (see Figures 3a, 3b and 3c) between the distribution panel 11 and the holding elements 12, such that, depending on the relative position of each of the studs 31 which are formed in the area of a side wall 16 or 17 of the distribution panel 11, it is possible to latch or snap into one of a plurality of recesses which are integrated in the guide sections 29 of the holding elements 12. As can be seen from Figures 3a, 3b and 3c, the projection 31 latches into different recesses in the holding element 12 and/or the guide section 29 depending on the relative position between the distribution panel 11 and the holding element 12.
The stud-like projections 31 are in the form of projections which are mounted in a sprung form, with the stud-like projections being mounted on a sprung section 32 of the respective side wall 16 or 17 in order to mount them in a sprung form. The sprung section 32 of each side wall 16, 17 is formed by slots 33 in the respective side wall 16, 17. In the embodiments shown in Figures 4, 6, the sprung section 32 is in this case integrated in the respective side wall 16, 17 such that the sprung section 32 runs at right angles to any relative movement between the distribution panel 11 and the holding elements 12. In contrast, in the embodiment shown in Figure 5, the sprung section 32 runs parallel to the direction of any relative movement between the distribution panel 11 and the holding elements 12. The direction of the relative movement between the distribution panel 11 and the holding elements 12 is indicated by double-headed arrows 34.
As already mentioned, each of the stud-like projections 31 which is mounted in a sprung form engages in in each case one of a plurality of recesses which are integrated in the guide sections 29 of the holding elements 12, in order to lock different relative positions between the distribution panel 11 and the holding elements 12, with the recesses having different contours in the illustrated exemplary embodiment.
First recesses 35 have a rectangular contour, with recesses 35 with rectangular contours such as these making it possible to move over a stud-like projection 31, which is mounted in a sprung form, in both directions of the relative movement (double-headed arrow 34) between the distribution panel 11 and the holding elements 12. As can be seen in particular in Figures 7a to 7d, the stud-like projections have a circular or else oval base area, with the projections 31 being curved at right angles to the direction of the relative movement between the distribution panel 11 and the holding elements 12 such that a guide section 29 of a holding element 12 can be moved over it, like a ramp.
In the situation in which a stud-like projection 31 such as this has been latched in a recess 35 with a rectangular contour, the stud-like projection 31, which is mounted in a sprung form, can be moved over and thereby overcome, like a ramp, in both directions of the relative movement, by application of an appropriate force. The projection 31, which is mounted in a sprung form, is then pushed back and therefore slides along an inner surface of the guide section 29 of the holding element 12 until it snaps or latches into a recess again. The first recesses 35 with the rectangular contour accordingly allow the stud-like projections 31 to be moved over in both directions of the relative movement (double-headed arrow 34) between the distribution panel 11 and the holding elements 12.
As can be seen in particular from Figure 2, second recesses 36 are integrated in the guide section 29 of the holding element 12, in addition to the first recesses 35 with the rectangular contour, and these second recesses 36 have a rectangular contour on one side, and a circular or else oval contour on another side. Such contouring of the second recesses 36 may also be referred to as a D-contour.
Recesses 36 such as these with a D-shaped contour make it possible to move over the stud-like projection 31 in a first direction of the relative movement between the distribution panel 11 and the holding elements 12, in which the projection 31 is pressed against the side of the recess 36 with a rectangular contour. In contrast, in the other direction of the relative movement, in which the stud-like projection 31 is pressed against the side of the recess 36 with a circular or oval contour, movement over the projection 36 is prevented, so that this makes it possible to define a limit position for the relative movement between the distribution panel 11 and the holding elements 12.
It should be noted that, in addition to or instead of the recesses 35 and 36 illustrated in Figure 2, recesses may be integrated in the guide section 29 of the holding elements 12, with a circular or else oval contour overall, and accordingly have a contour corresponding to the base area of the stud-like projections 31. Recesses with contours such as these prevent movement over a stud-like projection 31, which is mounted in a sprung form, in both directions of the relative movement (doubled-headed arrow 34) between the distribution panel 11 and the holding elements 12, so that, in this case, the sprung section 32 has an associated unlocking device in order to unlock a projection 31 which has been latched or snapped into a recess such as this.
An unlocking device such as this is preferably formed by a projection 37 on the sprung section 32 which, as shown in Figure 6, projects beyond the respective side wall 16 or 17 and the holding element 12, which is not shown in Figure 2. A stud-like projection 31 can be moved out of a recess by application of a force to the projection 37, in order in this way to allow relative movement between the distribution panel 11 and the corresponding holding element 12.
As already mentioned, the stud-like projections are curved at right angles to the direction (double-headed arrow 34) of the relative movement between the distribution panel 11 and the holdings elements 12 such that the guide section 29 of a holding element 12 can be moved over it, like a ramp. In this case, Figures 7a to 7d show possible embodiments of the curvature of the stud-like projections 31. These embodiments have the common feature that the curvatures increase in the direction of a central section of the projections 31, starting from sections of the projections 31 which are located at the front and/or are located at the rear in the direction of the relative movement (double-headed arrow 34), so that the curvatures have a local maximum in the central section of the projections 31 and a local minimum on the sections which are located at the front and at the rear in the direction of the relative movement.

Figure 1 shows a perspective plan view of one exemplary embodiment of an optical waveguide distribution device 10, with the optical waveguide distribution device 10 having a distribution panel 11 which can be mounted like a drawer via holding elements 12 on a rack in a distribution cabinet. In the illustrated example, the distribution panel 11 has a bottom wall 13 as well as four side walls 14, 15, 16 and 17, with the side wall 14 forming a front wall of the distribution panel 11, and the side wall 15 forming a rear wall of the distribution panel 11.

Fiaures 3a, 3b and 3c show different relative positions between a fixed holding element 12 and a side wall 16 or 17 of the distribution panel 11 in the optical waveguide distribution device 10 according to the invention, with the distribution panel 10 having been moved to the left with respect to the holding element 12 in Figure 3a, and with the distribution panel 11 having been moved to the right with respect to the holding element 12 in Figure 3b. In the position shown in Figure 3a, the distribution panel 11 is withdrawn, for example in order to form splices on optical waveguides which have been placed in the distribution panel 11, with respect to a rack to which it is attached via the holding elements 12. In contrast, in Figure 3b, the distribution panel 11 has been pushed back into the rack, to be precise beyond the position illustrated in Figure 3c, in order in this way, for example, to protect plugs acting on the front wall 14 of the distribution panel 11 against mechanical stresses.
A stud-like projection 31 is formed in the area of each of the side walls 16 and 17 of the distribution panel 11. The stud-like projections 31 interact with recesses within the holding elements 12 in order to lock different relative positions (see Figures 3a, 3b and 3c) between the distribution panel 11 and the holding elements 12, such that, depending on the relative position of each of the studs 31 which are formed in the area of a side wall 16 or 17 of the distribution panel 11, it is possible to latch or snap into one of a plurality of recesses which are integrated in the guide sections 29 of the holding elements 12. As can be seen from Figures 3a, 3b and 3c, the projection 31 latches into different recesses in the holding element 12 and/or the guide section 29 depending on the relative position between the distribution panel 11 and the holding element 12.
The stud-like projections 31 are in the form of projections which are mounted in a sprung form, with the stud-like projections being mounted on a sprung section 32 of the respective side wall 16 or 17 in order to mount them in a sprung form. The sprung section 32 of each side wall 16, 17 is formed by slots 33 in the respective side wall 16, 17. In the embodiments shown in Figures 4, 6, the sprung section 32 is in this case integrated in the respective side wall 16, 17 such that the sprung section 32 runs at right angles to any relative movement between the distribution panel 11 and the holding elements 12. In contrast, in the embodiment shown in Figure 5, the sprung section 32 runs parallel to the direction of any relative movement between the distribution panel 11 and the holding elements 12. The direction of the relative movement between the distribution panel 11 and the holding elements 12 is indicated by double-headed arrows 34.
As already mentioned, each of the stud-like projections 31 which is mounted in a sprung form engages in in each case one of a plurality of recesses which are integrated in the guide sections 29 of the holding elements 12, in order to lock different relative positions between the distribution panel 11 and the holding elements 12, with the recesses having different contours in the illustrated exemplary embodiment.
First recesses 35 have a rectangular contour, with recesses 35 with rectangular contours such as these making it possible to move over a stud-like projection 31, which is mounted in a sprung form, in both directions of the relative movement (double-headed arrow 34) between the distribution panel 11 and the holding elements 12. As can be seen in particular in Figures 7a to 7d, the stud-like projections have a circular or else oval base area, with the projections 31 being curved at right angles to the direction of the relative movement between the distribution panel 11 and the holding elements 12 such that a guide section 29 of a holding element 12 can be moved over it, like a ramp.
In the situation in which a stud-like projection 31 such as this has been latched in a recess 35 with a rectangular contour, the stud-like projection 31, which is mounted in a sprung form, can be moved over and thereby overcome, like a ramp, in both directions of the relative movement, by application of an appropriate force. The projection 31, which is mounted in a sprung form, is then pushed back and therefore slides along an inner surface of the guide section 29 of the holding element 12 until it snaps or latches into a recess again. The first recesses 35 with the rectangular contour accordingly allow the stud-like projections 31 to be moved over in both directions of the relative movement (double-headed arrow 34) between the distribution panel 11 and the holding elements 12.
As can be seen in particular from Figure 2, second recesses 36 are integrated in the guide section 29 of the holding element 12, in addition to the first recesses 35 with the rectangular contour, and these second recesses 36 have a rectangular contour on one side, and a circular or else oval contour on another side. Such contouring of the second recesses 36 may also be referred to as a D-contour.
Recesses 36 such as these with a D-shaped contour make it possible to move over the stud-like projection 31 in a first direction of the relative movement between the distribution panel 11 and the holding elements 12, in which the projection 31 is pressed against the side of the recess 36 with a rectangular contour. In contrast, in the other direction of the relative movement, in which the stud-like projection 31 is pressed against the side of the recess 36 with a circular or oval contour, movement over the projection 36 is prevented, so that this makes it possible to define a limit position for the relative movement between the distribution panel 11 and the holding elements 12.
It should be noted that, in addition to or instead of the recesses 35 and 36 illustrated in Figure 2, recesses may be integrated in the guide section 29 of the holding elements 12, with a circular or else oval contour overall, and accordingly have a contour corresponding to the base area of the stud-like projections 31. Recesses with contours such as these prevent movement over a stud-like projection 31, which is mounted in a sprung form, in both directions of the relative movement (doubled-headed arrow 34) between the distribution panel 11 and the holding elements 12, so that, in this case, the sprung section 32 has an associated unlocking device in order to unlock a projection 31 which has been latched or snapped into a recess such as this.
An unlocking device such as this is preferably formed by a projection 37 on the sprung section 32 which, as shown in Figure 6, projects beyond the respective side wall 16 or 17 and the holding element 12, which is not shown in Figure 2. A stud-like projection 31 can be moved out of a recess by application of a force to the projection 37, in order in this way to allow relative movement between the distribution panel 11 and the corresponding holding element 12.
As already mentioned, the stud-like projections are curved at right angles to the direction (double-headed arrow 34) of the relative movement between the distribution panel 11 and the holdings elements 12 such that the guide section 29 of a holding element 12 can be moved over it, like a ramp. In this case, Figures 7a to 7d show possible embodiments of the curvature of the stud-like projections 31. These embodiments have the common feature that the curvatures increase in the direction of a central section of the projections 31, starting from sections of the projections 31 which are located at the front and/or are located at the rear in the direction of the relative movement (double-headed arrow 34), so that the curvatures have a local maximum in the central section of the projections 31 and a local minimum on the sections which are located at the front and at the rear in the direction of the relative movement.
