Description

CONNECTION RULER. OF CUTTING OR SWITCHING Description: The invention relates to a connecting, cutting or switching strip according to the preamble of claim 1. The connecting and cutting strips used in the telecommunication and data technology are correspondingly equipped with DE 28 04 478 C2 knife and clamp contacts and allow the connection in a plane. The connection contacts on the side of the cables and on the switching side are arranged at the same working height on the front side. The strips are fitted on mounting plates and, if necessary, can be separated from the mounting plate again with an installation and removal tool. Such a mounting plate is also described in DE 28 11 812 C2. With these strips, for example, standard cable distribution boxes with twelve terminals each at 100 DA can be constructed. An extension is possible only by introducing more terminals in a new housing. The greater concentration of the connection in the predetermined space of a cable distribution box requires a miniaturization of the modules used at the expense of the available area for each contact slot in the ordering area and thus entails a worsening of the working conditions of the assembler as well as damage to the clarity of the connection. . The separation, which is becoming increasingly important and necessary, from areas of competence between the network administrator and the subscriber is difficult to achieve with the known modules of the telecommunication and data technology. In DE-G 94 00 303.3 a connection module is described, in which two rows of terminal strips are arranged at an angle of 90 ° to each other, which make it possible to apply the knife and terminal technique, as uras, esguarnec m os os, in the smallest space in the standard connection boxes of data and communication technology. It is disadvantageous that only connections can be made, but also can not be carried out cuts, commutations as well as controls and other functions. The purpose of the invention is to develop a connection, switching or switching strip of the type indicated at the beginning, with which the most varied switching, protection and measurement tasks in the telecommunication and data technology in the smallest space are guaranteed. , reliably with a higher density of connections and that is very clear and easy to use for the operator, the reliable separation of the areas of competence of the network administrator and of the subscribers must be ensured. The solution to this objective results from the features of claim 1. The arrangement of the two terminal strips preferably forming 90 * with each other, together with the knife and clamp contact elements formed according to the invention preferably through two planes and arranged at an angle, they make it possible to create a universally applicable terminal for the telecommunications and data technology, with which connection, switching and switching tasks are possible, as well as controls, measurements, protection and switching without interruptions. It is only necessary to exchange the contacts in the insulated body divided into two and insert the corresponding functional elements, such as plugs to protect against surges or the like. A protection of the respective strip can be ensured by the incorporation of a box, but the protection of a single double core can also be carried out. A considerable reduction in the dimensions of the strip is achieved and at the same time a field of "order" is emencms emencms great eyc aro, so that in a standard cable distribution box a density of connections is achieved 33% greater and at the same time an available surface greater by almost 40% for each contact slot in the area of ordering.The ordering side is oriented in the final position of the strip towards the assembler and allows a comfortable and reliable connection, as well as visually clear, of the power strip. The connection of the strip in two planes makes it possible to prevent by means of appropriate measures that the wiring of the wire side of the cables located below can be manipulated, for example by means of a sealable frame. The connection of the terminal strip in two planes also allows the separation of the areas of competence, namely the side of the network administrator (side of the cable webs below) and the subscriber side (top side of the network) ). The mounting plate equipped with two lines of engagement, in which the fitting openings are arranged on the side surfaces, so that a smooth upper edge is preserved, greatly eliminating a danger of injury to the assembler, guarantees in the first position of the terminal strip fits comfortably and reliably as well as lightly, and in the second position a final position of the secure strip, difficult to manipulate and only separable with the connecting tool. The rear side of the mounting plate has an elongated hole which, by simple loosening of the fixing device for the rope or for the cutting plug, makes it possible to adjust it without jumps, so that they can run adjacent to one another several cable cords through the back wall of the mounting plate. Other embodiments of the invention provide for fixing the strip on profiled rails or on a flange, to which the • reg is screwed. Other advantageous structures of the invention result from the dependent claims. The invention is described in more detail below with the aid of the exemplary embodiments, represented in the drawings, of a connecting strip and of a cutting and switching strip. They show: figure 1 the front elevation view of a strip, formed from the insulating body divided in two (upper and lower part), figure 2 the rear elevation view of the strip according to figure 1, figure 3 the bottom plan view of the strip according to figure 1, figure 4 the plan view from above on the strip according to figure 1, figure 5 the sectional representation (cut BB) of the strip according to figure 1 with a cutting or switching contact inserted, figure 6 the plan view from above on the cutting or switching contact of figure 5, figure 7 the sectional representation of the strip according to figure 1 with a connection contact inserted , figure 8 the plan view from above on the connecting contact of figure 7, figure 9 the sectional representation of a cable distribution box with insertion container, mounting plate with terminal strip and cover protection against dust, figure 10 the front elevation view of the mounting plate and figure 11 the side elevation view of the mounting plate according to figure 10.

The connection, switching or switching strip is preferably applied for the connection of cable wires and installation wires, insulated with synthetic material, for example in terminals for the realization of, for example, cable distribution boxes in local power networks. telecommunication cable. A terminal box consists, for example, of ten strips for each of ten double webs, a mounting plate 9 and a name plate with a label (not shown), which can be used as an adapter for the correction of the connection on the side of the cables. The structure of the strips according to the invention decreases the size of the lattice of a terminal in such a way that in a port of a cable distribution box can be inserted instead of three terminals as hitherto and four terminals. The packing density of the connections rises by 33%, at the same time achieving considerably greater clarity and more space for the sorting field. The area available to the fitter rises in the order zone for each contact slot by almost 40%. Through the connection, which occurs in two planes, of the strip, the side of the webs of the cables is located below and the side of the sorting field is located above, turned 90"and directed towards the assembler, it can be lowered by means of appropriate measures ", for example through a sealable frame, the possibility of manipulation of the side of the cables' webs (zone of the administrator of the network). The separation of the administrator side of the network and the subscriber side allows a separation of the competition zones. From the representations in the figures 1 to 5 you can see the structure of the strip. The insulating body of the strip is divided into two and correspondingly corresponds to the representation in figures 1 and 5 of an upper part and a lower part 3, 4. The upper part 3 and the lower part 4 are fitted together, at an angle 90 ', through fitting openings 10 provided on both sides in the upper part 3 of the terminal block and with hooks 37 provided on both sides in the lower part 4 of the terminal strip, after fitting with the contact elements knife and clip 7, 8 (figures 6, -8). The insulating body formed by the upper part and the lower part 3, 4 (housing parts) is formed identically for carrying out the various functions of the terminal block (connecting, cutting or switching strip). The various functions of the strips are achieved exclusively through the equipment with different knife and clamp contact elements according to figures 6 and 8 and through the equipment with additional peripheral boxes or the like. Correspondingly to the representation in FIG. 1, the terminal strip 1 formed in the upper part 3 has contact grooves 11 and the terminal strip 2 formed in the lower part 4 has contact grooves 12, which form an angle between each other. 90 'and through which a connection is respectively produced. The terminal strip 1 forms the ordering side RS for the connection of the protruding webs on the subscriber side and the terminal strip 2 forms the cable side KS for the connection of the incoming webs of the network administrator. In figure 1 the means 32 are also shown, 33 are known for guiding the webs of the cables and the connecting elements 5 for fitting the terminal strip to a mounting plate 9 (FIGS. 10, 11) or to a profile (not shown). The strips can be aligned at will. The simple fitting of the strips on the mounting plate 9 saves expensive screw connections and also offers the possibility of unlocking the individual mounting strips from the mounting plate 9 if necessary with the aid of a pull-out unlocking knife on the connection tool (not shown). . The strips are fitted correspondingly to the representation of the mounting plate 9 in FIGS. 10 and 11 in two positions on the mounting plate 9. In FIG. 11 two rows of fitting are shown., 17 on the side walls 34 of the mounting plate 9. For the comfortable connection of the terminal block with the incoming wires from the cable side KS, the terminal strip is first brought into its connection position I (FIG. 11) and is fitted for this purpose with the lace elements 6 (FIG. 2) in the fitting openings 18 of the lace row 16. After that the strip is loosened and fitted by means of a rotation of 90 * with the lace elements 5 (FIGS. a 4) in the lace openings 19 of the lace row 17 (figure 11) to its final position II (figure 11). The engagement of the terminal strip in the final position II can only be released by unlocking the engagement with the unlocking blade, while the engagement in the connection position I is releasable without auxiliary means. It results in a visually clearer field of order and compared to the considerably higher state of the art, oriented towards the assembler, which guarantees a reliable and comfortable connection. The introduction of the fitting openings 18, 19 in the side walls 34 of the mounting plate 9 has the advantage that the edges 35 of the side walls 34 are smooth and do not cause any danger of injury during the assembly of the strips. The mounting plate 9 has correspondingly to the representation in figure 10 an elongated hole 21 for the seamless adjustment of the cable cords or of the cutting plugs, which allows the cable cords to be arranged adjacent to one another. comfortably on the rear wall of the mounting plate 9 without fully loosening the fixing device. Figure 4 shows the plan view from above on a strip, as it is presented to the assembler, when the strip is fitted on the mounting plate 9 in the final position II. The contact grooves 11 and 13 are oriented towards the assembler on the side of the ordering field RS and the contact grooves 12 are rotated 90 * relative to it on the cable side KS. The strip is correspondingly shaped to the representation "in section in FIG. 5, by means of the insertion of a cutting contact element 7, as a cutting or switching strip, the cutting contact element 7 according to FIGS. formed by a U-shaped knife and clip connection contact 24 with a tap contact 25 and by an L-shaped knife and clip connection contact 26 with a tap contact 27. The two tap contacts 25, 27 form, in the plane of the ordering side RS, a functional socket 28, in which a socket 15 of an arbitrary functional element, not shown, is guided to satisfy a desired function, for example a protection against overvoltages. 14 can also be designed as a switching zone, eliminating the bend 36 in the flange of the tap contact 25 and carrying the contact flange 25 straight. The wires of the outgoing wires of the subscribers are connected to the knife and clamp connection contact 24, the incoming cable webs of the network administrator are connected to the knife and clamp connection contact 26 rotated 90 'with respect to the connection contact 24. In figure 6 it is represented in a view in plant from above the contact element of knife and clamp 7 (cutting contact). Figure 7 shows the sectional representation of a strip which is designed as a connection strip with knife and clip connection contacts 8. The knife and clip connection contact 8 is formed in one piece from two connection contacts of knife and clamp 29, 30 arranged one, functional socket 31. The functional socket 31 and the knife and clamp connection contact 29 are accessible from the ordering side RS, the knife and clamp connection 30 must be connected from the side of KS cables. Figure 8 shows a plan view from above on the knife and clamp connection contact 8, as used in the strip according to FIG. 7. The knife-clip connection contact 29 is thus bent at 45 * with respect to the functional socket 31. In FIG. contact elements of a strip fitted on the mounting plate 9 are largely protected against fouling and condensation formation by fitting an insertion container 22 onto the mounting plate 9 and by means of a dust protection cover 23.
