Figure 1 shows a perspective plan view of an 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 as a drawer through retaining elements 12 on a shelf in a distribution cabinet. In the illustrated example, the distribution panel 11 has a lower 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 retaining elements 12 act on the side walls 16 and 17 of the distribution panel
11, a relative movement of translation between the distribution panel 11 and the retaining elements 12 being possible, in order to move it like a drawer. As can be seen in figure 1, gaps or openings 18 are integrated in that side wall 14 of the distribution panel 11 which is in
shape of a front wall, in which the couplings of openings or openings 18, which are not illustrated, can be inserted or hooked, for connectors which are not illustrated. It should be noted that couplings like these can 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 mainly used for handling and / or as a reservoir for splices which are formed between optical waveguides that have been prefabricated with connectors in a end and optical waveguides that have been inserted through an optical waveguide cable in the distribution panel 11. Optical waveguides that have been prefabricated at one end with connectors are also referred to as spikes. The splices between the prefabricated optical waveguides and the optical waveguides that have been inserted through an optical waveguide cable in the distribution panel 11 are kept in receptacles 19 for the splices, the receptacles 19 being an integral component of the distribution panel 11, which is in the form of an injection molded plastic part. Those non-connector ends of the optical waveguides that have been prefabricated with connectors at one end can be passed to the receptacles 19 through guide elements 20 and at the same time ensure that the minimum bending radii are maintained for the guide rails. wave
optics. Those ends of the prefabricated optical waveguides that have been prefabricated with connectors, can also be passed to the couplings, which are not illustrated, for the connectors through guides 21 which are arranged adjacent to the front wall 14 of the control panel. distribution 11, and comply at the same time with the minimum permissible bending radii, with the couplings that are not illustrated being accommodated in the openings 18 in the front wall 14. Other guide elements 22 for the prefabricated optical waveguides are placed between the guide elements 20 and 21 and form a storage medium of excessive length 23 for the prefabricated optical waveguides. At least one optical waveguide cable with optical waveguides guided therein can be inserted into the distribution panel 11 of the optical waveguide distribution device 10 illustrated in FIG. 1, specifically through an aperture. 24 which is integrated in the rear wall 15 of the distribution panel 11. In order to release the tension of the optical waveguide cables that have been inserted in the distribution panel 11, the distribution panel 11 has tension release devices. for the optical waveguide cables, wherein the optical waveguides that have been inserted through the respective optical waveguide cable into the distribution panel 11, can be passed through guide elements 26 towards the receptacles 19 for the splices and comply at the same time with the minimum permissible bending radii for the optical waveguides. Other guide elements 27 for the optical waveguides that have been inserted into
Through an optical waveguide cable in the distribution panel 11 they form a storage medium of excessive length 28 for the same. The receptacles 19 for splices between the prefabricated optical waveguides and the optical waveguides that have been inserted through an optical waveguide cable in the distribution panel 11 are an integral component of the distribution panel 11, which it is in the form of a part of injection molded plastic, in the same manner as the guide elements 21, 21, 22, 26 and 27 as well as the tension release devices 25. As already mentioned, the distribution panel 11 it can be fixed to a shelf, preferably to a distribution cabinet, by means of retaining elements 12 which act on the side walls 16 and 17 thereof, and can be moved back and forth in translation with respect to to the retaining elements 12, in the form of a relative movement of the drawer type. As can be seen in particular in FIGS. 1 and 2, the retaining elements 12 have guide sections 29 which act on the side walls 16 and 17 of the distribution panel 11, and / or are guided thereon. In addition, the retaining elements 12 have fastening sections 30 which are at an angle to the guide section 29 and through which the optical waveguide distribution device 10 can be fixed to a shelf, in particular in a distribution cabinet.
When an optical waveguide distribution device 10 is fixed to a shelf in a distribution cabinet, the position of the retaining elements 12 is fixed, but the distribution panel 11 can be moved in a translation manner with respect to the retaining elements 12, specifically in the form of a relative movement of the drawer type. Figures 3a, 3b and 3c show different relative positions between a fixed retaining 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 panel of distribution 10 having been moved to the right with respect to the retaining element 12 in figure 3a, and with the distribution panel 11 having been moved to the right with respect to the retaining element 12 in figure 3b. In the position shown in figure 3a, the distribution panel 11 is removed, for example in order to form splices in optical waveguides that have been placed in the distribution panel 11, with respect to a shelf to which it is fixed through the retaining elements 12. In contrast, in Figure 3b, the distribution panel 11 has been pushed back towards the shelf, specifically beyond the position illustrated in Figure 3c, so that, for example, the connectors acting on the front wall 14 of the distribution panel 11 against mechanical stresses. A stile type projection 31 is formed in the area of each of the side walls 16 and 17 of the distribution panel 11. The stile type projections 31 interact with gaps within the
retaining elements 12 in order to block different relative positions (see Figures 3a, 3b and 3c) between the distribution panel 11 and the retaining elements 12, so that, depending on the relative position of each of the uprights 31 which are formed in the area of a side wall 16 or 17 of the distribution panel 11, it is possible to snap or snap-fit one of a plurality of recesses which are integrated in the guide section 29 of the retaining elements 12. As shown in FIG. can see in Figures 3a, 3b and 3c, the projection 31 engages in different recesses in the retention element 12 and / or the guide section 29, depending on the relative position between the distribution panel 11 and the retention element 12. The upright type projections 31 are in the form of projections which are mounted in a spring-like manner, with the upstanding projections being mounted in a spring section 32 of the respective side wall 16 or 17 with In order to mount them in a spring-like manner. The spring 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 spring section 32 in this case is integrated into the respective side wall 16,17 so that the spring section 32 runs at right angles to any relative movement between the distribution panel 11 and the retaining elements 12. In contrast, in the embodiment shown in Fig. 5, the section of spring 32 runs parallel to the direction of any relative movement between the distribution panel 11 and the retaining elements 12. The direction of relative movement between the panel
of distribution 11 and retaining elements 12 is indicated by double-headed arrows 34. As already mentioned, each of the stud-type projections 31 that are mounted in a spring-shaped manner is in each case coupled into one of a plurality of recesses that are integrated in the guide sections 29 of the retention elements 12, in order to block different relative positions between the distribution panel 11 and the retention elements 12, with the recesses having different profiles in the exemplary embodiment illustrated . The first recesses 35 have a rectangular profile, with recesses 35 with rectangular profiles such as those that make it possible to move on a projection of the upright type 31, which is mounted in a spring form, in both directions of the relative movement (double arrow). head 34) between the distribution panel 11 and the retaining elements 12. As can be seen in particular in figures 7a to 7d, the stud-like projections have a circular or oval base area, with the projections 31 being curved at right angles to the direction of relative movement between the distribution panel 11 and the retention elements 12 so that a guide section 29 of a retention element 12 can be moved thereon, like a ramp. In the situation in which a stile type projection 31 such as this one has been hooked into a recess 35 with a rectangular profile, the stile type projection 31, which is mounted in the form of a spring, is
it can move and thus overcome, like a ramp, in both directions of relative movement, by applying an adequate force. The projection 31, which is mounted in the form of a spring, is subsequently pushed back and therefore slides along an interior surface of the guide section 29 of the retaining element 12 until it snaps or snaps back in a hole. The first recesses 35 with the rectangular profile therefore allow the upright-type projections 31 to move in both directions of relative movement (double-headed arrow 34) between the distribution panel 11 and the retaining elements 12. As can be seen in particular in figure 2, the second recesses 36 are integrated in the guide section 29 of the retention element 12, in addition to the first recesses 35 with the rectangular profile, these second recesses 36 have a rectangular profile on one side, and a circular or oval profile on another side. Said profile of the second recesses 36 can also be referred to as a profile D. The recesses 36 such as those with a D-shaped profile make it possible to move the stile-type projection 31 in a first direction of relative movement between the distribution panel. 11 and the retaining elements 12, wherein the projection 31 is pressed against the side of the recess 36 with a rectangular profile. In contrast, in the other direction of the relative movement, where the stile type projection 31 is pressed against the side of the hole 36 with a circular or oval profile, it is avoided
the movement on the projection 36, so that this makes it possible to define a limit position for relative movement between the distribution panel 11 and the retaining elements 12. It should be noted that in addition or instead of the holes 35 and 36 illustrated in FIG. Figure 2, the recesses can be integrated in the guide section 29 of the retaining elements 12, with a general circular or oval profile, and consequently have a profile corresponding to the base area of the upright projections 31. Gaps with profiles such as these prevent movement on a stile type projection 31, which is mounted in the form of a spring, in both directions of relative movement (double-headed arrow 34) between the distribution panel 11 and the elements of retention 12, so that in this case, the spring section 32 has an associated unlocking device for the purpose of unlocking a projection 31 that has been engaged or adjusted Pressed into a hole such as this one. An unlocking device such as this is preferably formed through a projection 37 in the spring section 32 which, as shown in Figure 6, projects beyond the respective side wall 16 or 17 and the retaining element. 12, which is not shown in Figure 2. A stile type projection 31 can be moved out of a gap by applying a force to the projection 37, so that relative movement between the distribution panel 11 and the corresponding retaining element 12.
As already mentioned, the upright type projections are curved at right angles to the direction (double headed arrow 34) of the relative movement between the distribution panel 11 and the retaining elements 12 so that the guide section 29 of a retaining element 12 can be moved on it, like a ramp. In this case, figures 7a to 7d show possible modalities of the curvature of the upright projections 31. These modalities have the common characteristic 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 backwards in the direction of 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 in the sections that are located in front and back in the direction of relative movement.
