Wire guide element for a distributor unit in telecommunication systems. The plug connector strips of the distributor unit are secured to the edges of a vertically aligned U-shaped carrier part.
A hollow plastic member is used as a wire guide element for the lines proceeding between neighboring distributor units arranged at both sides. With the guide peg present at the under side, this hollow plastic member is plugged, on the one end, onto the upper edge of the leg of the carrier part and, on the other hand, is snapped onto the retainer plate joined in this region to the carrier part at the back side. At least one hook attached to the upper side parallel to the plate also serves for the ordered guidance of lines. At its front side, the hollow member has a slot specifically designed for the insertion of lines.
2~77~3 BACKGROUND OF THE INVENTION
The present invention i6 directed to a wire guide element for a distributor unit in telecommunication systems that is composed of an oblong and essentially U-shaped carrier part for accepting plug connector strips for connecting and joining outgoing and incoming lines. This carrier part is in turn brought into a ready-to-use installation state on the basis of a retainer element firmly connectable thereto given longitudinally vertical alignment. An expansion is possible on the basis of at least one identical distributor unit to be attached laterally and line leads proceed between respectively two such neighboring distributor units. A
separate cover hood can be put in place on each distributor unit.
Such a distributor unit serves the purpose of running patching wires from any arbitrary terminal point of the plug connector strips for incoming lines to any arbitrary terminal point of the plug connector strips for the outgoing lines leading for, example, to the switching equipment. In modern distributor systems a surveyable wiring arrangement must be provided sven for increasing wiring density. In order to achieve such an ordered laying of lines, for example, hook-shaped or bow-shaped wire guide elements are arranged in the region of the wire guide waves that are provided. Given a correspondingly high number of subscribers, a distributor unit may also be expanded by identical distributor units to be arranged in immediate adjacency at both sides.
It i5 an object of the present invention to enable an optimum guidance of the lines to be laid between the distributor units on the basis of correspondingly matched and placed guide elements.
This is achieved in that the wire guide element is fashioned as a plastic part and, for the purpose of forming a transverse channel between two immediately adjoining sub-units, represents a hollow 2~77~
member open at two oppGsite sides whose lower wall region has outwardly directed guide pegs with which it can be directly plugged onto the face edge of every leg of the carrier part open toward the front. A mechanical connection to the retainer element projecting beyond the carrier part in the longitudinal direction occurs by fastening elements attached to the back side.
In accordance with the development of the present invention, a hook-like formed portion that continues in a finger-like, resilient tab is provided as fastening element at the back side.
A cut-out is provided at the plate serving as retainer element, being provided in the region of each and every leg. For mechanical joining, the hook-like formed portion embraces the lower edge of the cut-out and the resilient tab snaps in under the upper edge of this cut-out.
2~5'~7~3 As a result thereof, the conductors can be placed into the wire guide element in a simple way.
The features of the present invention which are believed to be novel, are set forth with particularity in the appended claims.
The invention, together with further objects and advantages, may best be understood by reference to the following description taken in conjunction with the accompanying drawings, in the several Figures in which like reference numerals identify like elements, and in which:
FIG. 4 depicts an enlarged portion of the fastening element;
29577~3 and FIG. 5 is a plan view of the front side of a distributor unit.
DESC~IPTION OF TH~ PREFER~ED EM~ODIMENT
According to FIG. 1, the basic unit provided, for example, for mounting at a wall is composed of the carrier part 1 and of the plate 3 connectable thereto in the upper and lower region.
The carrier part is fashioned U-shaped and is manufactured as an extruded profile, whereby any desired length dimension is then respectively possible by simply cutting off from the extended material. On the basis of a corresponding design of the free edge of each and every leg of this U-form of the carrier part, the plug connector strip 6 or, respectively, 7 can be secured to these edges. To this end, for example, the free edge of the one leg can comprise a through, potentially slightly inwardly inclined completely cylindrical form. A plug connector strip that has its end face provided with a cut-out adapted thereto is then plugged onto this completely cylindrical form. The other leg comprises a through screw channel at the free edge. After the plug connector strip is plugged onto the fully cylindrically fashioned edge of the other leg, the respective plug connector strip is to be put in place onto the edges of the screw channel at any arbitrary location at the long side of the carrier part, for example with a flange attached in said plug connector strip. Given a corresponding perforation of the flange, the plug connector strip can be secured to the carrier part 1 in the screw channel with a self-taping screw. For forming a distributor block, the carrier part accepts (in the way just set forth) a plurality of plug connector strips 6 or, respectively, 7 that have their long sides following one another. For example, plug connector strips 7 wherein terminal elements are provided at the long sides lying opposite one another can be employed as plug connector strips 7. In accord therewith, 2~77~3 for example, the terminal elements for the lines that lead to the switching equipment and that are seldom rearranged are arranged at the back side of the strip. These lines of the internal side outgoing as cable 8 can already be connected at the factory. They are connected to a plug device 9 for contacting to the cooperating contacts present in the switching equipment. The terminal elements for the external side, i.e. for the subscriber lines, continue to be provided at the front, servicing side of the strip. These terminal elements are thus easily accessible, so that alterations in the occupation of the strip can be undertaken without further ado. For the ordered guidance of the lines, bow-shaped or hook-shaped wire guide elements 10 are to be snapped in place in a simple way at the one leg of the U-shaped profile. A vertical channel for guiding the lines is thus be available with these elements.
For fasteninq to the wall, the carrier part 1 has its upper and its lower end screwed to a plate 3 fashioned C-shaped. This plate projects beyond the carrier part 1 both in longitudinal direction as well as at one side. With such a plate, a defined spacing between the distributor block and a wall surface can be observed after installation. Cables are to be guided in this wall spacing region. On the basis of appropriate clips 4, the perforations present in the laterally projecting part of the plate 3 serve the purpose of fastening the cables laterally held by the wire guide elements 10. After, for example, being deflected from above into the space prescribed by the carrier part 1, the appertaining conductors are then conducted to the plug connector strip 7. The illustration of FIG. 1 also shows a rail-like element 5 that serves the purpose of fastening accessory equipment. In its normal position, it is hooked to the upper edge of the plate 3.
After being completely equipped, a distributor unit can be provided 2~77~3 with a cover hood 11. This cover hood 11 comprise6 recesses at both sides that are to be covered with inserted and locked plastic parts 14. These recesses serve the purpose of enabling transverse channels when a distributor unit is expanded by an identical distributor unit to be respectively arranged in immediate lateral proximity.
The multiply provided guide pegs 13 are offset relative to one another in accord with the shaping of the leg of the carrier part. When the wire guide element 2 is put in place, these pegs embrace the upper edge of the profile. The hook 17 is introduced 2~77~3 into the cut-out 24 that is provided in the plate 3. The wire guide element 2 is moved downward until the hook 17 embraces the lower edge of the cut-out 24. During this emplacement motion, the resilient tab 18 is first conducted along the corresponding wall of the plate 3, whereby it supports itself with a defined spr$ng power. When the final position is reached, the resilient tab 18 snaps into the cut-out 24 at the upper edge of the cut-out 24 with its rib l9 applied to it. A locking is thus achieved, so that the wire guide element can only be removed after a simple, manual unlocking. The final position that has been assumed is thus secured by the said fastening elements in combination with the guide pegs 13.
A hook-shaped formed portion 16 that has a detined spacing from the plate 3 is additionally provided at the upper side of the wire guide element 2. Cables or, respectively, conductors can likewise be guided in this space between the plate 3 and the hook-like shaped portion 16. This, for example, prevents such conductors from tilting over toward the front side.
The equipping of the distributor unit with the individual elements is indicated in the distributor unit shown without cover hood in FIG. 5. Proceeding from a prescribed marking line M, a field of plug connector strips 7 is present above this line and these, for example, are allocated to the internal side as separating or disconnect strips. The conductors 25 to be connected to these strips, consequently, lead to the switching equipment.
As already mentioned, these lines are secured with, for example, spring clips 4 to the plate 3 that laterally extends beyond the 2~7~3 profile of the carrier part 1. The insertion, contacting and fastening onto the plates 3 is provided away from the profile in order to avoid threading given a later expansion. Proceeding from the fastening location at the upper plate 3, the individual conductors are guided from above to the separating or disconnect strip 7 and are connected to the terminal elements thereof. These terminal elements are usually fashioned as clamp elements that allow a stripping-free connection of the electrical conductors.
For example, the conductors leading to the switching equipment can be connected to the terminal elements provided a the under side of the separating or disconnect strip. The terminal elements present at the upper side thereof are then present for the variable connections to be occupied within the scope of what is referred to as jumpering. These are easily accessible from the front.
Protective plugs 28 are to be plugged as needed onto the plug connector strip 7 allocated to the internal side.
