Description

Device for creating molded cables, in particular for telephone systems

The innovation "relates to a device for creating of molded cables, with coded markings on the insulation of the jumper wire in front of each soldering point applied, which identify the connection te lie, to which the soldering point is assigned, with one for the continuous coloring of the insulation sheaths of the jumper wires known paint spraying device, especially for Fernspre systems.

It is particularly important for wiring in telephone systems It is necessary to distinguish the individual jumper wires in the molded cables according to certain types of current, e.g. according to minus and plus potential, ringing current, speech current, etc. and, if possible, to mark each current path between i or more connection terminals differently. It is known to use jumper wires with different colored insulation jackets for this purpose, which are necessary in order to obtain an identification of the connection points to be connected in the finished cable. So it is common in telephone systems to bkooibinat ionen certain types of current thirteen different colors assign and seventeen colors to identify certain To keep current paths open for the respective wiring. So there are thirty different types of paint To keep stock and to process which changes when in use

multiply η times from different cross-sections for the wiring. The creation of a molded cable from a large number of different types of jumper wires, the arrangement requires a corresponding number of rolls of jumper wire on the cable board. Removing mistakenly seized Jumper wires from the bundle, which often occurs with the large number of jumper wires used, is very time-consuming .

It is designed to be convenient and to simplify the wiring work has been proposed for circuit boards, the jumper wire to be laid by machine on the circuit board by removing the jumper wire from a supply roll Wiring head is fed, with which it automatically strips the insulation at the soldering points, in a certain direction is set, looped into openings in the circuit board and cut to size. At this proposed machine arrangement, the circuit board is with the help of an installation slide under the wiring head of a moved to the other opening »automatically".

If you want to transfer this mechanical process to the production of molded cables, it fails economically because that a separate lead screw is available for each type of stop wire is required in the wiring head and a corresponding look!

difficult to find because the color coding alone is not unique.

The task of the innovation is now to create a device designed in such a way that the creation of differently coded shaped cables or jumper wires is facilitated.

According to the innovation, this is done in that the! device with several color nozzles with differently sized openings and / or each with a specific color fed, is provided that the respective paint nozzle in the path through which the jumper wire traverses can be swiveled in by hand or by machine and the device in the area of the set nozzle moves the point of the jumper wire to be marked in as many steps as it does the number of marks to be applied required1? and between the steps briefly brings the nozzles to effect. A device designed in this way is suitable for both the creation of the molded cable by hand, as it can be easily arranged on the cable board and operated by hand, as well as for automatic control in a machine cable forming device.

Below is the innovation based on in the drawing

In Fig. 1 is an embodiment of the device shown in principle. Is on a rotatable shaft 1 a carrier 2 attached. In recesses 3 on the carrier 2, only one of which is shown, there is a paint container 4- mounted tiltable about an axis 4. Each color ; container 4 is connected to a claw-shaped nozzle 6, on the inside of which a passage opening, not visible in the drawing, is provided for the dye. the The passage opening can have a shape or dimensions that differ from nozzle 6 to nozzle 6. In the undressed The position shown is the nozzle 6 in its working position, in which it includes a jumper wire 7 and the paint container 4-, a with an Eolben S under a solid arranged pressure stamp 9 comes to rest. When twisting of the carrier 2 slide the paint pots 4 along a curved, fixed stop 10 against which the paint pots 4 put on. The stop 10 is designed so that the paint pots 4 and the nozzles 6 are outside the working position into the position shown in dashed lines.

The jumper wire 7 is abgenoisisenj in a manner known per se from a supply roll shown at its ™ end stripped, pulled to the cable board, on a first cable pin attached and according to your wiring diagram between the cable pins inserted. When the last cable pin arrives, the jumper wire is cut, stripped and connected fixed to the last cable pin of this wire pull. Finally, the ones lying in the course of the jumper wire become one Loop-shaped connecting elements cut and stripped.

In accordance with the increase in price, the retaining wire 7 is attached to the in Fig. I shown device passed. At the beginning of the SöhaXtärahi? 7 at its end and further on

run with markings on all intermediate soldering parts that are fixed at their distances from one another, which are applied in the amount of the soldering points to be stripped to its insulation by the device. This is done by pulling the jumper wire 7 up to the point to be marked by hand or by machine Device pulled, the nozzle in question 6 set by turning the shaft 1 by machine or by Eand and through a not shown cam over the Bruükstespel 3 the paint is sprayed on. If several brands of the same type are to be applied, one is also used manually or mechanically operated stepping drive of the jumper wire 7 by one step during the standstill of the aforementioned cam is moved further, whereupon this cam actuates the plunger 9 again. On that the next nozzle 6 is set and the paint application continues.

Since the applied marking takes up as little space as possible - and should be able to be applied in a few work steps, the marking is created according to a code system.

In. 2, the marking 11 on the jumper wire 7 consists of marks 12 and 13 of the same color and of different widths. The marker 12 can z, B _s, the number ^"n is 5 and the Mark © the number,? ^{N is} 1, so that the number of the example shown is" 14 "in at this Eodesystem device has the position shown in FIG ·. 1 have only two nozzles 6, which are fed with the same color.A single nozzle 6 can also be used if the jumper wire for the wider marks 12 is moved past the nozzle 6 while the color is being sprayed on.

With larger numbers, the space required for the marking is used, even if a third mark is added by others

Width, very large, which is why a code system shown in FIG. 3 is used. This saves so much space that several markings 11, 11 and 11 "have to be accommodated with otherwise the same space requirement. Each of the markings 11 to 11" consists of marks 14 to 18 of the same width but different colors, indicated by hatching in the drawing. Within each of the markings 11 and 11 *, each mark, for example 14 and 15, is assigned to a decade and its color means one of the digits "1" to "0". The numerical meaning of the color can be set up according to the internationally established color-number code. If, for example, the color marks 14 mean the number "3", 15 the number "8", 16 the number "2", 17 the number "0" and 18 the number "1", then counted from the respective soldering point with the three markings 11 shown, in the order from left to right, the numbers "38", "82" and "82" marked, while the three markings 11 * from left to right the numbers "20", "1" and " 1 "mean. The three similar markings 11 ″ shown consist only of a numerically indistinguishable color mark 19, which stands for the continuous color of the jumper wire used up to now, and with which the affiliation to a certain type of current is identified, e.g. whether the jumper wire in question is connected to plus or minus or whether it carries calling or speech current. With this marking, the connection point to which the jumper wire is to be connected, the device to which the connection point belongs and finally the assignment to a certain type of current can be read off Read the following in the middle of the jumper wire 7, shown in dashed lines: The incoming end is to be connected to connection point "82" of device "1" and is directly connected to minus. The outgoing end is also connected to connection point "82" of device "1 ¹ . ¹ and is consequently also directly on minus via this soldering point.

One can also, with those lying in the course of the jumper wire 7 Solder joints for the incoming or outgoing end Apply marking that indicates the previous one or on the following solder joint.

The wiring consists of twisted together If there are holding wires 7, the twisting is inherent after the markings have been applied to the individual holding wire 7 known way to be carried out by two spindles rotating around one another before the twisted jumper wires 7 are formed will.

From the foregoing it can be seen that this has been the case so far known process for the production of Forrakabel only one Jumper wire or only a few colors of jumper wire in stock must be kept and processed so that the mechanical implementation of the Pormkabe! production is economical it becomes possible that the control of the jumper cables In the finished molded cable and in the installed state, the soldering points can be checked largely without ringing out that the markings are clear and can be read directly. The procedure that can be carried out with the device also has beneficial repercussions on the creation of wiring diagrams and wiring tables, since these are provided with simpler position information sources of error when creating the forra cable be reduced.
