Description

Rack wiring for telecommunication systems, in particular telephone switching systems The invention relates to rack wiring made up of loose, in guide elements led jumper wires for electrical connection of lines in the frame already built-in components, their connection elements with their soldering points in a connection plane lie, for telecommunications systems, especially telephone exchanges.

The aim of the invention is the wiring and its management and To arrange fastening parts on the frame in such a way and to train them in such a way that that a complete wiring of the frame with automatically controlled tools becomes possible.

The wiring of components built into single frames or rails to be carried out by machine in that one automatically controlled according to the wiring diagram Tools used and the soldering after mechanically fixing the jumper wires by immersion or wave soldering in one operation is known. For this purpose one arranges the components on the single frame so that their connection points form a level with their soldering points, which is the outer boundary of the populated Represents single frame on one side and the single frame and one the wire feeding, automatically controlled wiring head from solder joint to solder joint moved relative to each other, which the jumper wire between the frame plane and the solder joint level. The sections extending from solder joint to solder joint The jumper wires are used between the components and the components to component extending sections along the edges of the single frame guided the tool.

It is also known to use wiring instead of molded cables To make racks by individually drawn loose single wires and these, as far as they run side by side, held together by cuff-shaped links or to be inserted in cable ducts with insertion slots. With this arrangement «the Single wires through a hand-held one and the single wire at the desired points Stripping tool inserted into the cable ducts. For laying the individual wires by means of an automatic tool that only performs precisely defined movements can, however, this arrangement is not suitable. In these known arrangements are the parts on the frame that lead the jumper wires with built-in components only partially freely accessible from one side of the frame. Furthermore, the for the Guide wire from single frame to single frame in the rack is available standing area perpendicular to the actual wiring level so far in depth of the frame or extend those assigned to the components of a row Guide elements perpendicular to the connection plane so deep into the frame that it would be very difficult to make a mechanical tool, that can perform appropriate movements.

A gesture wiring consisting of individual loose jumper wires to be attached to the frame in a simple manner, it is known along the frame supports Cable ducts open to the front and also along the lines attached to the frame to use cable pockets that are open to the front and open into the cable ducts. The individual Jumper wires inserted, whereupon the openings of these lead the loose jumper wires Parts are locked or close by themselves. This facility prepares with a machine creation of the rack wiring difficulties so far, than - during the laying to be carried out with the cable ducts and lugs open - Pull exerted on the jumper wires by the tool a pulling out of its already inserted section would cause.

According to the invention, a complete wiring of the frame and optionally several racks assembled to form a rack row unit with automatically controlled tools thereby that a) the guide elements for the jumper wires on the frame or on the components and are arranged on the frame in such a way that they allow the insertion of the jumper wires in a allow a single direction from the frame center plane to the soldering points, that b) the guide elements, seen on the connection plane, freely accessible on the frame Distributed over three wiring levels, one behind the other, parallel to the connection level whose distance from one another is not greater than that given by the maximum number the jumper wires to be laid require a certain amount of space, and that c) the guide elements are distributed on the three wiring levels in such a way that the connection element to connection element of a component extending sections (connection channel) of the Jumper wires as close as possible to the connection plane on the side of the connection elements (e.g. soldering lugs) run in the first wiring level, while that of Component to component of a row extending sections (row channel) of the Jumper wires on the side of the components in the second and moving from row to row extending sections (frame channel) of the jumper wires laterally of the rows in the third wiring level.

This way will be used for laying all jumper wire sections achieves that the tool can move in one plane relative to the frame, the built-in components, the guide elements and the sections that have already been laid the jumper wires do not hinder the further laying that the transition from one Wiring level to the other only a relatively small movement of the tool perpendicular to the wiring plane and that finally requires the insertion of the jumper wires only bilateral movements of the tool are necessary in the guide elements are. This makes the device necessary for wiring so simple that your Use for automatic wiring of an assembled frame, economical becomes possible.

In order to prevent that at the transition point from the line channel to the gesture channel, on which a large number of individual wires are to be led in racks, one Difficulty laying occurs due to jumper wires that have already been laid in advance According to a development of the invention, one with the components on both longitudinal edges equipped, a line-forming carrier each arranged a line channel, and the from the row channel to the frame channel overlapping jumper wires are each in which of the following line to which the jumper wire is to be led, turned away from the line channel. This creates a das at the transition point Insertion facilitating crossing of the jumper wires.

In the case of so-called patch panels, it is known that the arbitrary Connection to connection via the jumper field to be pulled over the jumper wires to lead individual so-called shunting eyes through which the shunting wires are threaded or in which they are hung. All you need is so many shunting eyes to be arranged, how deflection points exist and how support points are necessary are.

It is also known to solder components such. B. from Solder and fuse strips, wire ends brought in through wire guide plates secure in their position, which for this purpose with openings, slots or the like. are provided. The advantages associated with these known devices will be exploited for the present purpose according to one embodiment of the invention, that the guide elements attached to the frame as individual, detachably attached, with their insertion openings directed away from the connection plane and angle hooks the guide elements assigned to the components as attached to the components Wire guide plates are formed.

This allows the angle hooks depending on the requirements of the wiring can be arranged on the frame on a case-by-case basis, and it becomes special, its own Wire guide part having constructions of the components avoided.

According to a further embodiment of the invention, the guide element is “nit its recesses associated with the connection elements on one side of the component attached and an auxiliary comb attached to the opposite side of the component, in the recesses of the connection element to connection element of the relevant Component extending portion of the jumper wire guided and held in loops will.

As a result, several electrically independent connections can be made with a single jumper wire Connections can be made without the jumper wire being reattached each time and must be returned to the area of the connecting duct. The jumper wire is continued from one connection to the other on the side of the auxiliary comb and the section bridging the connections severed, one known per se Working method, which is particularly useful for the machine creation of the gesture wiring is cheap. After the bridging sections have been separated, the auxiliary comb holds the here often very short jumper wires of the individual connections are stuck.

To the given space between the fastened components for accommodating the ones extending from connector element to connector element To be able to largely utilize sections of the jumper wires is, according to a development of the invention for components whose connection elements are on two parallel rows distribute on the component, the guide element as a toothed on both longitudinal edges Comb formed, which, lying parallel to the connection plane, on the connection elements is attached and its teeth protrude beyond the component on both sides. A connection element designed in this way can also be easily attached to the component apply.

In rack wiring according to the invention, that is at one end jumper wire attached to a connection is subjected to tensile stress, which is its mechanical Fixing on the connection element endangered. For such cases it is known to use the connections to be provided with recesses, which have a resiliently widening inlet opening for the jumper wire, which is slightly smaller than its diameter and which have acute angles abutting inner edges in which the Jumper wire pinched under the influence of the pull exerted on him. It is but does not prevent the connecting element as such under the influence of the Jumper wire device and is bent.

To get an interception of the wiring tool onto the jumper wire to achieve the train exerted during its laying in front of the connecting element, can the resilient property of being used as soldering tails trained connection elements, how they z. B. are available in power strips, are exploited.

According to a further embodiment of the invention, this is done by that in components whose connecting elements are flexible, in one or in two Rows arranged soldering tails are formed, a) the guide element close to the Connection elements is attached to the component that b) the connection elements to the Guide element except for a distance which is less than the diameter of the Jumper wire is, or bent to resilient concern and that c) the Recesses in the guide element are arranged so that they are bent from the Connection elements are partially overlapped.

Is the one pressed into one of the recesses from the center plane of the frame Jumper wire attached to the cushioning connection element or routed around it, so it is secured against falling off by the springs in its position ready to be soldered, and a pull exerted on the jumper wire has in the direction of the connection elements a component acting on this, which the connecting element to the Attempts to pull the guide element, whereby the jumper wire is clamped even more tightly will.

In the case of other components, it is known that those designed as solder lugs Arrange connecting elements in a row and alternately crop the soldering ends. To secure the connection elements in the direction of their row and a guide To achieve the jumper wire in a space-saving manner, is according to a further Embodiment of the invention in components whose connecting elements are a row of soldering lugs with alternately bent soldering ends, a) the guide element parallel to the row of connection elements on the component below the shoulders of the soldering ends bent on this side so that the shoulders these soldering ends in the recesses of the guide element, and b) will a second guide element lying parallel to it can be released on this guide element attached, which in the assembled state on the other side of the component comes to rest in such a way that between its teeth the shoulders one after the other Side cranked soldering ends, and c) the alternating cranked ends Soldering ends held by an attached guide comb, the teeth of which are on both of his Edges are offset from one another and the component on both sides tower above.

With such a design, the one required for the guide element Space is limited to a minimum, the guide elements secure the freely protruding ones Soldering ends in their mutual position and that of the frame center plane the soldered hookup wire is inserted into the recesses of the guide element held.

The invention is illustrated below with reference to in the drawings Embodiments described. 1 shows a partial view of a frame with the wiring according to the invention, FIG. 2 is a view of the narrow side of the frame according to FIG. 1, FIG. 3 shows the wiring according to the invention of a component in the area of the connection channel, FIG. 4 shows the wiring according to the invention of a Component of another embodiment in the region of the connection channel, FIG. 5 a Embodiment of the connection of the wiring using a guide element another embodiment, FIG. 6 shows a further embodiment for guide elements in its mounted position on the Ger position line, Fig. 7 is a part of one in the Multi-part wiring to be used on the component according to FIG. 6 8 shows a further part of the guide element according to FIG. 7, FIG. 9 shows a third part of the guide element according to FIG. 7, FIG. 10 shows a plan view on the end face of the guide element according to FIG. 7 in the assembled state.

1 and 2 show a section of a frame 1, 2, which consists of two frame supports 1 and a carrier 2, which is equipped with components 3. Several such carriers 2 are attached to the frame supports 1 one above the other and one below the other. As an example for the components 3, plug-in connector strips were selected here, the connecting elements 4 of which are designed as soldering lugs lying in series. On the frame 1, 2 guide elements 6 and 7 are attached to the frame supports 1, guide elements 8 on the carrier 2 and guide elements 9 on the structural elements 3. The guide elements 6 to 8 consist of angle hooks and are detachably screwed to the frame 1, 2. The guide elements 9 are designed as wire guide plates known per se, are provided on their free longitudinal edges with recesses 10 opposite each connection element 4 and are fastened laterally to the components 3. As can be seen from FIG. 2, in the installed state, the soldering ends 11 (FIG. 3) of the connection elements 4 which form the soldering points lie in a plane which is referred to as the connection plane. The guide elements 6 to 9 are distributed on the frame 1, 2 that loosely guided jumper wires 12 extend from them in three planes on the frame. The sections extending from connection element to connection element 4 of a component 3 and forming connection channels 13 run perpendicularly in a first wiring plane parallel to and in the vicinity of the connection plane. The sections extending from component to component 3 and forming row channels 14 run horizontally on the two longitudinal edges of the carrier 2, which represents a row 15 of the frame 1, 2 and lie in a second wiring plane. The sections of the jumper wires 12 which extend from row to row 15 and form frame channels 16 run perpendicularly in a third wiring plane. The three wiring planes are parallel, viewed in the direction of the frame center plane, one behind the other at a distance that is determined by the maximum number of jumper wires 12 to be laid. The line channels 14 come to lie outside the area of the connection channels 13 and the frame channels 16 outside the area of the connection and line channels 13 and 14. The guide elements 6 to 8 are directed with their insertion sides away from the aforementioned connection plane and the recesses 10 on the guide elements 9 are arranged so that the insertion of the jumper wire 12 in the connection channel 113 and its guidance to the corresponding soldering end 11 of the connection element 4 from the frame center plane can be done here, or vice versa. Depending on requirements, the jumper wires 12 are combined in the gesture channels 16 at certain intervals by a bandage 17 after they have been laid. As can be seen from Fig. 2, those sections of the jumper wires 12 which overlap from the row channels 14 to the gesture channels 16 are guided in such a way that those of the jumper wires 12 which are to be guided from one row 15 to another, not shown, row, are laid in the row channel 14 facing away from the next row. Thus, in FIG. 2, those jumper wires 12 which are to be led via the gesture channel 16 to a line above it in the drawing, not shown, are arranged in the drawing channel 14 which is lower in the drawing. This creates jumper wire crossings at a transition point 18 , on both sides of which a guide element 6 and 7 are arranged, whereby the insertion of the jumper wires 12 into the guide elements 6 and 7 at the transition points 18 is facilitated.

In such an arrangement, the machine wiring of the assembled frame 1, 2 is carried out as follows: The wiring is carried out with the aid of a wiring head, not shown, with which the jumper wire 12 can be guided, stripped and attached to the connection elements 4. . The wiring head is also designed in a manner known per se so that it can be rotated about its axis and displaced along its axis, while the frame 1, 2, guided by a compound slide, also known per se, not shown, moves according to two coordinates of the Can move frame center plane relative to the wiring head. One end of the jumper wire 12 is fixed to one of the connection elements 4 in the wiring plane after stripping. By moving the frame, the jumper wire is guided over the recess 10 in the guide element 9 , pressed in by moving the wiring head and pulled out by a subsequent movement of the frame 1, 2 over the guide elements 8 delimiting the associated connection channel 13, whereupon it passes through the wiring head over the second wiring level is led out and is thus inserted between the legs of the guide elements 8, which are directed downward in FIG. 1. The frame 1, 2 is now moved up to the level of another connection channel 13, into which the shaft wire 12 is to be inserted, and is withdrawn from the wiring head into the first wiring level. In this case, this portion 2 again sets of the jumper wire in the making of the rearward-facing legs of the guide members 8 limited line channel 14 in Fig. 1 now the frame 1, such movement, that the switching wire 12 in the amount of the desired connection channel 13 from there is brought to the desired recess 10 of the guide element 9 arranged here, is pressed into this by a movement of the wiring head and is guided by a further movement of the frame 1, 2 to the associated connection element 4 and is fixed to it. This game is repeated for each section of the jumper wire 12 that extends from your connection channel113 to the other until the moment when the guided end of the jumper wire 12 comes to lie behind the second wiring level again. From here, by alternating movements of the frame 1, 2 and the wiring head, the jumper wire 12 is hooked into the guide element 6 assigned to the corresponding row channel 14 and into the guide element 7 facing the row to be wired, which defines the gesture channel 16 . With the same play of movement between the frame 1, 2 and the wiring head, a jumper wire 12 can also be laid, which is intended to extend over several frames 1, 2 of a row of frames.

The machine wiring of entire equipped racks can therefore go through the described arrangement of the guide elements 6 to 9 by simple bilateral Movements that are easy to implement by machine can be made.

Fig. 3 shows a device with which in the region of the connection channel 13 a tightly successive wiring of the connection elements 4 is facilitated and the laying of several electrically independent connections can easily be carried out in a single wiring harness. For this purpose, an auxiliary comb 21 , likewise designed as a wire guide plate, is attached or detachably attached to the component 3 opposite the guide element 9, the recesses 22 of which are offset with respect to the recesses 10 of the guide element 9. If, as shown in section 23, electrically independent connections are to be made to closely spaced connecting elements 4 with a single wire, the jumper wire 12 is guided from soldering point to soldering point over the guide element 9 and the auxiliary comb 21 in a meandering manner and attached to them, whereupon the from connection to connection extending, dash-dotted sections are removed. The small independent connecting sections from the jumper wire 12 are held in place by the guide element 9 and the auxiliary comb 21 until they are soldered.

Since the jumper wire 12 is under tension during laying, the guide elements must be designed so that the smallest possible component of the train acts on the connecting elements 4. In order to achieve this, a guide element 9 'shown in FIG. 4 is used in the case of a component 3, the connecting elements 4 of which, as is often the case, are distributed over two parallel rows. The guide element 9 ' is designed as a toothed comb on both longitudinal edges, which is pushed onto the connecting elements 4 and the teeth 24 of which protrude beyond the component 3 on both sides. By inserting the jumper wire 12 between two of the teeth 24 extending transversely to the connection elements 4 , a pull exerted on the jumper wire 12 is partially intercepted by the connection element 4 and essentially has only one component in the longitudinal direction of the connection element 4 . In addition, this arrangement of the guide elements 9 ′ parallel to the front side of the components 3 makes it possible to make good use of the connection channel 13 for accommodating the jumper wires 12.

Fig. 5 shows a component assigned to the component not shown here Guide element 9 ", which is preferably use in such components finds, in which connection elements 4 'are designed as flexible soldering lugs. The guide element 9 ″, designed as a wire guide plate, is close to the and assigned to the component parallel to the row of connection elements 4 '. As shown, can thereby the connection elements 4 'with their soldering ends 11' easily on the guide element 9 ". The recesses 10 of the guide element 9" lie to the Connection elements 4 'offset in the direction of their row that edges 25 of the connection elements 4 'partially overlap the recesses 10. The edges 25 are in the area of the recesses 10 provided with recesses 26, which. as shown, trapezoidal could be. The jumper wire 12 is with its stripped point in one of the Depressed recesses 10 and, as shown in the middle connection element 4 ', wrapped around this. When pressing the jumper wire 12 into the recesses 10, the connecting element 4 'resiliently yields until the jumper wire 12 enters the recess 26 of the connecting element 4 'engages. In the connection element on the right in the drawing 4 ', the jumper wire 12 is continued and in a preceding intermediate position shown while pressing. In this version, a the jumper wire 12 exerted train the connection element 4 'to the guide element 9 ″, whereby the fuse of the jumper wire 12 in the recess 10 is supported. At the same time, all connected connection elements 4 'are through the jumper wires 12 secured in their position to one another in the direction of their row. The teeth 27, which delimit the recesses 10, have beveled surfaces 28 to facilitate the insertion of the jumper wire 12. The jumper wire 12 lies down when a pull is exerted on him in the direction of the dashed arrow into the acute angle of the recess 26, where it clamps.

Fig. 6 shows guide elements 9 '' 'in their position, which they when attaching occupy line 15 (FIG. 1), not shown here. The illustrated guide elements 9 '' 'are primarily used for components on their connecting elements a plurality of connecting wires 12 is to be soldered. Every guiding element 9 '' 'has recesses 10', which in a manner known per se from a consist of a slot accessible bore. This slot is of a somewhat smaller clear width than the connecting wire 12 to be inserted. The one in the drawing not visible component is provided with connection elements 4 ", which like the Components 4 'are bent in Fig. 5 and rest against the guide element 9' ''. The connection elements 4 ″ point at their edges that overlap the recesses 10 ′ Solder lugs 29, which are provided with notches 30 on their end faces, so that together with notches 31 on the front edges of the connecting elements 4 "each Terminal element 4 "three solder points are available. The latter can be used for soldering a bare wire multiple 32 indicated by dashed lines can be used, which be soldered to the connection elements 4 "after completion of the rack wiring can. The strain relief and the holder of the connecting elements 4 "is as in the Arrangement according to FIG. 5 ensured. The guide elements 9 ″ 'can punch on the components itself or, as shown, attached close to these on the carrier 2 (Figure 1) will.

In FIGS. 7 to 10: a guide element 9 ″ ″ is shown which is used in components 3 ′ which carry a series of connection elements 4 ″ ′, the soldering ends 11 ″ of which are alternately bent. The guide element 9 "" is designed and arranged on the component 3 'so that it requires as little space as possible to the side of the component 3' so that the connecting channel 13 running there is not restricted by the guide elements. The guide element 911 ″ is arranged above the component 3 ′ and below the shoulders 33 of the soldering ends 11 ″ which are cranked towards its side on a longitudinal side of the component 3 ′. In openings 34 of the guide element 9 ″ ″ a second guide element 36 designed as a wire guide plate is suspended via hooks 35, which extends parallel to the first on the other side of the connection elements 4 ″ ″ and between whose teeth 37 the shoulders 33 of the latter extend Insert the 11 "soldered ends that are offset from the side. The protruding soldering ends 11 ″ are secured in their position relative to one another by an attachable guide comb 38, the teeth 39 of which are offset from one another on its two longitudinal edges and overlap the component 3 ′ on both of its longitudinal sides, as is the case with the guide element 9 ′ shown in FIG. the case is.

As can be seen from FIG. 10, the connection channels available are 13 on both sides of the component 3 by such a guide element 9 "", 36 not constricted at all. The management and definition of the not shown here Jumper wires 12 (Fig. 1) through two attachable guide elements 9 "" and 36 allows subsequent, easy-to-install attachment to the component 3 '. This is of particular advantage in the case of spring strips to be wired, which in Find connector strips for insertable circuit boards and which, how known, by pressing between two boards forming the actual connector strip to be assembled.
