Abstract
ABSTRACT
The carrier unit that is formed from an essentially U-shaped extruded profile incorporates projections that are continuous in the longitudinal direction. These can be used as screw, clamp, snap and plug channels for the attachment of functional elements that go to make up such a distribution unit. In order to provide for the attachment of the terminal strips, the multi-functional extruded profile has at the edge of one arm a completely cylindrical shape and, on the edge of the other arm of the U, a screw channel. The terminal strip is installed with corresponding hollow cylindrical cut-outs on the fully cylindrical moulded edge that forms a point of rotation and, on the opposing side surface, the flange that is formed thereon, by means of a screw connection. Because of the point of rotation, simple installation of the terminal strips is possible and even in the case of a fully installed cross-connection system it is possible to pivot [the terminal strips] during fault-finding sequences or in the event that repairs are necessary.

Description
2 ~
The present invention relates to a carrier unit populating the terminal strips of a distributor board for a telecommunication system, said terminal strips being used to join and connect incoming and outgoing electrical lines, and with other functional elements that go to make up such a distribution frame, it being possible to connect this rigidly to at least one attachment element that is used for final assembly in order to produce a level of assembly that is ready for use.
A distribution frame of this sort is used to run jumper lines from any connection point on the terminal strip for incoming lines to any connection point on the terminal strip for the outgoing lines that go, for example, to the exchange. Different distribution areas are provided for each of these lines. In the case of distribution frames that are configured as cabinet or wall distributors, the terminal strips are secured to carrier structures that are produced as racks or blocks, for example, by welding, bolting up, or riveting. In the case of distribution panels in which wire guideways run both horizontally and vertically, it is a problem to wire these in a manner that can be easily followed, particularly with reference to the jumper lines that have to be run.
It is the task of the present invention to so configure a carrier unit that it is possible to keep to an easily followed arrangement, even with the increasing density of wiring that is , 2~7~9 encountered in modern distribution systems, which permits particularly simple installation, and which makes it simple to run or change the lines that are to be connected.
This has been achieved in that it i8 formed from an extruded metal profile that is of essentially U-shape; in that the individual wall sections of this, which are used to secure the functional elements, incorporate projections that can be used for screw, clamp, and plug channels; and in that on the face side of each arm of the U-shaped extruded profile there is in each instance a projection that extends in the longitudinal direction and which is used to attach the terminal strips.
The screw, plug, and clamp channels that are provided in the .j :
multi-functional extruded profile according to the present invention are used to simplify the attachment of all the functional elements that are required for a distribution frame.
In addition to the terminal strips, these are, for eYample~
straps that are used to hold cables, hook or stirrup-shaped wire-guide elements, and retaining elements, to which the additional modules and special components can be secured. The attachment of these essential functional elements is achieved in the simplest possible way by suspending them, or by snapping them into place.
Because of the pre-shaped channels, it is possible to provide screw connections at the places at which, for example, electrically conductive connections are also required.
', ~' ~ f~ 7 o ~i ~
According to the present invention, a screw channel that is open to the outside is moulded into the top that joins the two arms of the U-shape. In the simplest possible way, this permits connection with a retaining element that is used, for example, to provide attachment to a wall. The retaining element can be formed, for example, from a plate that is, at least, U-shaped.
Thus, the basic unit for final assembly on a wall is simply the extruded profile with, for example, two stand-off plates. This results in a very low installed weight, which, in in its turn, permits installation by only one person. By simply cutting the extrusion, one obtains a carrier unit that is of the desired length.
According to a further development of the present invention, on the unattached edge of one arm of the U-shaped extrusion there is at least one semi-cylindrical projection. This forms a point of rotation for a terminal strip, which ensures simple installation.
~t tho ~ame tlmo, thl8 also mean~ that, even ~n the case of fully installed cross-connections, it is possible to pivot the terminal strip when fault-finding or when making repairs. Each terminal strip is fixed in place by means of a moulded-on attachment flange, by using a screw channel that i5 provided on the free edge of the other arm. The hollow, cylindrical matching shape that corresponds to the moulded-on point of rotation is advantageously provided on the unattached edge of at least one ~ J ~ ~
connector strap that faces in the longitudinal direction of the terminal strip.
A further development of this carrier unit is such that on the outer wall surface of at least one arm there is a channel that is of hook-shaped cross-section and in that in the direction of the face side, at an appropriate distance, there is a continuous extension that incorporates a run-up slope that forms an obtuse angle with the outer wall surface and which can be used, as required, for the plug-in or snap attachment of a wire-guide element, the attachment of which is matched to this. These wire-guide elements can be hook or clip shaped. In the case of a vertical orientation of the carrier unit when in its final installed state, these wire-guide elements, which are snapped in as required, form a common channel for both the internal and the external side, and makes it much easier to search for wires in the event of a breakdown. Thus, the lines can be run in an orderly fashion within preset limits.
Additional advantageous developments of the present invention are shown in the remaining sub-claims.
The invention will be described in greater detail below on the basis of one embodiment shown in the drawings appended hereto.
These drawings show the following:
~37~ 39 Figure 1: a cross section through a carrier frame;
Figure 2: an exploded view of a distribution frame;
Figure 3: a plan view of the front of such a distribution unit.
The carrier unit shown in figure 1 is U-shaped. Both the two arms 8, 9 and the top 14 that combines these two arms to form a U-shape have quite specific projections. In order to form a distribution block, such a carrier unit accommodates a plurality of terminal strips 16, 17 that are aligned with each other on the long side. The carrier unit 1 is produced as an extruded profile, and it is possible to achieve any length by simply separating the "yard goods." The unattached edge of one side wall 3 of the carrier unit 1 incorporates a continuous cylindrical shape 2 that is optionally inclined slightly inwards.
A terminal strip 16 or 17, which incorporates an appropriately matching cut-out, is pushed onto this cylindrical shape 2. When this is done, the terminal strip can be moved in the manner of a hinge. Thus, what is formed is a point of rotation that simplifies attachment and manipulation. The other arm 9 has, at its unattached upper edge, a continuous channel 3. After the installation of a terminal strip, which is indicated in figure 1 by the broken line, on the edge of the arm 8 that is configured as a cylindrical shape 2, each terminal strip is secured by its flange 28 to the carrier unit 1 at any point on the long side of the carrier unit. As is shown in the drawing, an additional cut-out that matches the cylindrical shape 2 can be provided on the ~7~'3 one face side of the terminal strip. Because of this, during the attachment of strain-relieving lines, in order to populate their particular connecting elements with lines of this kind or to change the dressing of the wires, the terminal strips can be rotated through 180- and secured for this work that has to be done by simple insertion and being secured by screws. For this reason, there is no problem connected with using terminal strips in which, in a space-saving and economical manner, the connector elements are provided on the opposite long sides of such strips.
For example, the connecting elements for the lines that are seldom moved and which run to the exchange can be arranged on the back of the strip. These outgoing lines for the internal side can already be connected [at the factory]. Then, all that has to be done is to connect the subscriber lines or the lines that go to other floor distribution boards to the connector elements of the associated distribution strips. These connector elements are provided, as before, on the front service side. Thus, this side of the strips is easily accessible so that changes to the connections on this strip can be made easily.
In order to provide for the orderly routing of the lines, stirrup or hooked wire-guide elements 24 are simply snapped to one arm 8 of the U-shaped profile. To this end, on the outside wall of the arm 8, in its lower area, there is a channel-like section 12.
Also on this outer wall there is a projection ll that extends outwards at an obtuse angle. This particular shape gives rise to 2~33'~'t a run-up slope 10 for the wire-guide element that is to be clamped into place and which can be formed, for example, as a so-called "jumper hook" 24. A vertical channel for gulding the lines is made available with this jumper hook that is snapped into the profile described above as and when required.
Additional screw channels 5 or 6 are moulded into the top 14 of the U-shaped profile. For attachment to a wall, the carrier section 1 which has been cut to a suitable length is screwed into place with two spacer plates 22. When this is done, the sockets 5, 6 are used as screw channels so that this plate 22 can be secured to any point on the carrier section, for example, by using self-tapping screws. Using such a plate, a specific distance between each distribution block and a wall surface can be maintained, even after installation. Incoming or outgoing cables can be dressed within chis wall stand-off area.
On the inside wall of the arm 8 or 9, respectively, there are recesses that form a groove 13 or 7, respectively. An additional screw channel 4 is moulded onto at least one inside wall, and it i5 best that the upper edge of this does not extend beyond the lower edge of the groove 13. Thus, it is possible, for example, to slide connector straps 25 into these grooves 13 or 7, respectively, within the profile. These connector straps can then be fixed at any point with the help of the screw channel and the use of self-tapping screws, for example. By doing this, it is possible, in a very simple way, to divide the interior space ~ V~
of the U-shaped carrier unit into two areas. Because of the connector straps that are to be introduced into the grooves 13, 7 in the interior, it is also possible to secure additional component groups or structural units.
The plate or panel 22, discussed above, the jumper hooks 24 and the connector straps 25, as well as the terminal strips 16, 17, are shown in the exploded view at figure 2 as installable individual parts. As an example, the terminal strips 16 can serve as so-called separators, to which the cables 18 that lead to the exchange can be connected at the connector elements, as discussed above. The individual lines of the cable 18 are connected at their other connection side to a plug 19.
Additional strips 21 can also be provided as additional elements of a distribution unit, and these can be installed very simply on the upper edge of the panel 22 that projects at the side. These strips are provided with universal slots in order to permit the incorporation of various additional modules or special components. Clips 20 can be installed on the upper edge of a profile section 1 that is installed vertically. These clips are used to form transverse jumper channels in those cases when one additional distribution unit is immediately adjacent to another such distribution unit. In the event that more than one distribution unit is involved, these clips 20 will simultaneously serve to protect the lines that are dressed within them from damage that could be caused, for example, by the edges of sheet ;
g ~
metal covers 26 that are also installed. These covers 26 have openings on both sides for such transverse channels, and these openingsare covered by means of plastic plates 27 that are inserted and snapped into place when no such transverse channels are required. Normally, no additional components are required to secure these covers for they are simply hooked over the projecting edges of the plate 22.
The view of the front of a distribution unit shown in figure 3 shows that two areas are provided for the terminal strips.
Starting from an established marker line M, above this line there is a field of terminal strips, which, for example, are associated with the internal side as separators, i.e., the lines 18 that are connected to these strips lead to the exchange. These lines are secured to the plate 22 that extends at the side beyond the profile of the carrier unit 1, this being done, for example, by means of spring clips 23 that can be inserted into cut-outs that are provided for this purpose. It is intended that these system lines be installed, connected, and secured to the panel 24 from the outside of the profile in order to avoid having to thread the wires in the event of subsequent expansion. The individual lines are led from above from the point of attachment on the upper panel to the individual strips 16 and then connected with the connector elements on the lower side of these. As a rule, these connector elements are in the form of clamping elements that permit the connection of the electrical lines without insulation.
The present invention relates to a carrier unit populating the terminal strips of a distributor board for a telecommunication system, said terminal strips being used to join and connect incoming and outgoing electrical lines, and with other functional elements that go to make up such a distribution frame, it being possible to connect this rigidly to at least one attachment element that is used for final assembly in order to produce a level of assembly that is ready for use.

The connector elements on the upper side of each strip are provided for the variable connections that are to be populated within the framework of so-called jumper connection. They are readily accessible from the front. If necessary, protective plugs 28 are to be installed on the terminal strips 16 that are associated with the internal side.
The lines in the external cable 30 are not cross-connected directly; rather, the lines are clipped onto connector elements on jumper strips that are arranged beneath the line M. Then the actual cross-connection between the connector elements on the front of the separators and the connecting elements on the jumper strips are made. The expansion of the distribution panel is simplified as a result of specific marking of the separation of the strip fields that is made, because expansion is effected by the downwards or upwards away from these markings. Figure 3 shows that a distribution panel, which is shown here without its cover, can be expanded by additional units of this kind. The clip 20 that is installed in such a case on the upper edge of the profile fits at least partway into the area of the distribution block that is immediately adjacent. At the same time, this covers the edges of the cover 26 that is installed so that there can be no damage to the insulation of the transverse lines.

The plate 22 extends on one side and, slightly, on the other side beyond the profile. This makes it possible to install the cover 26 directly onto these pro;ecting edges of the plate.
