In the drawing, the same reference numbers refer to the same parts throughout.

In FIG. 1, a core provided with notch receptacles for a connection module can be rotated in the direction of an arrow A. In FIG arranged between a motor 21 and a bearing 23. For the purposes explained in detail below, the Core 10 by means of a conventional drive transmission 24 arranged between the motor 21 and the core rotated by 180 ° each time. Fig. 3 shows the dwell position of the core 10 in which the angle θ is expedient is as small as possible. The core 10 consists of a non-conductive material, for example plastic.

109821 / HU

A coil 26 wound with insulated wire 27 "is rotatably mounted in a known manner, so that the wire 27 can be unwound from the spool 26 by tension and an automatic Wire feed for winding the core 10 is guaranteed. The wire 27 is on a rotatable roller 29 the module core 10 out. The boll 29 is mounted in a winding device 30 which, by means of a guide 32 and a lead screw 35 is movably guided in such a way that the position of the wire 27 relative to the core 10 in the direction the arrows B can be controlled as a function of the rotation of the lead screw 35. The lead screw 35 is with a Page attached to a stepper motor 36 and attached to the stored in a warehouse 39 on the other side. In this way, the lead screw 35 is stepwise in both directions of rotation rotatable. In a modified arrangement, the lead screw 35 can move the module core 10, the device 30 remains stationary. The tension of the wire 27 can be adjusted by means of the position of the roller 29 on the winding device 30 determining adjustment slot 34- adjustable be.

A computer 37 or other suitable data processing device causes the supply of control signals to the motors 21 and 36 depending on accordingly programmed data of the connection module to be produced and thereby controls incremental displacements of the winding device 30 and the rotation of the module core 10 by 180 ° in each case. This creates 10 turns of wire on the core, which run through certain notches 12 or 14 in accordance with a predetermined pattern, which is fed into the computer 37 by the Data is given (Fig. 2).

The typical operation of the apparatus of FIG. 1 is gradual. It does so with every step

109821 / UU

Displacement of the device 30 and the further rotation of the core 10 by 180 ° in succession. During such a step, for example, the core 10 is initially in the dwell position, while the computer 37 triggers the shifting of the winding device 30 and thus the wire to a position opposite a certain notch 12 or 14 into which the wire 27 according to the computer 37 stored data is to be inserted below. As soon as the winding device 30 is in the appropriate position, the computer 37 triggers a rotation of the core 10 by 180 °, so that the wire 27 enters the λ notch provided for this purpose. Depending on the connection data, these steps can be repeated any number of times until the desired arrangement of turns on the core 10 is completed. Fig. 2 shows an intermediate stage in the manufacture of a typical winding arrangement. The beginning and end of the wire wound on the core 10 are anchored to it as desired, for example by means of an adhesive by winding or clamping or embossing in corresponding devices arranged on the core.

After attaching depending on the connection data in a certain order by predetermined Notches 12 and 14 running turns on the module core f 10 are found in the next step of the production of clamping jaws 41 use on both side edges of the core 10 in each case to attach a connection blank 40. Each individual connector 42 of the blank 40 occurs in one of the Notches 12 in which it coexists with the previous winding of the core remains optionally arranged therein wire windings. Accordingly, the notches 12 hereinafter referred to as connection notches 12 to distinguish them from the notches referred to below as blind notches 14, which do not take up any connecting parts. The blind notches 14

1 0 9 8 2 1 / U U

are not indispensable, but their use provides significantly expanded connectivity between the Connection parts 42 of the finished connection module. the Blind notches 14 are preferably narrower than the connection notches 12 in order to enable a compact construction, and alternate with these. However, equally wide notches and other arrangements of the same are also within the scope of the invention applicable.

FIG. 5 shows a typical connection blank 40 as used in FIG. The dashed lines 46 and 47 denote the position of the edges of the core 10 when clamping according to FIG. 4. Furthermore, the dashed line shows 47 the point at which the connecting blanks 40 after the clamping in the clamping jaws 41. Furthermore, the dashed line 47 together with the dashed Line 48 shows at which points parts of the connection blank 40 in the further course of the production of the connection module be separated.

The underside of the clamped arrangement shown in FIG. 4 is then prepared for dip soldering. For this purpose, the parts of the wire windings that run over the underside of the core 10 and those on it subsequent, in the notches 12 and 14 entering parts removed the insulation. Dip soldering then takes place the arrangement according to FIG. 4, for example, from the bottom to the dashed line 49. The lower Parts of the notches 12 and 14 filled with solder so that between any wires arranged in connection notches 12 and in jointly arranged connection parts 42 and between each jointly arranged in a blinker notch 14 Wires create an electrical connection.

109821 / UU

As the next step in the production of the connection module, the parts of the wire windings running on the underside and the angled parts of the connecting blanks 40 are removed from the dip-soldered side of the arrangement in a cutting and / or grinding process. The resulting arrangement is shown with the soldered side at the top in FIG. 6. The clamping jaws 41 are then removed and the module core 10, together with the wires 27 and the remaining parts of the connecting blanks 40, is embedded in a suitable casting compound. Finally, the terminal blanks are separated 40 along the overall ä dashed line 48th

7 shows a finished, embedded connection module 50. It has the casting compound 49 and the connection blank is separated to individual connections 42 of the module. To facilitate the insertion of the connection module 50 in a printed circuit, the connections 42 are preferably formed with increasing length (FIG. 8).

An embodiment suitable for flat stacking of the connection module is shown in Fig. 9. This embodiment can be easily produced from the arrangement according to FIG. 6 by making the connecting blanks at right angles before embedding turns.

10 and 11 show two schematic examples of typical connection arrangements of the connection module, such as by appropriate control of the device according to FIGS. 1 to 3 when the wire windings are attached to the module core 10 are achievable. The solid lines represent those wires 27 that run along the top of the core 10 accordingly Fig. 2 run, and the dashed lines

109821 / UH

Wires 27 running long the underside of the core 10 · During the further manufacture of the connection module, the Wires 27 on the underside removed as will be remembered, so that for electrical connection of the connections of the finished module only the wires shown in solid lines remain.

Thus, the winding pattern of FIG. 10 results in the finished Connection module electrical connections between inserted in notches A and B and between notches C and E. used connections. In contrast, the pattern of Fig. 11 results in a mutual connection of all of the finished module in the notches A, B, C, D and E inserted connections. These examples show how to go through appropriate Order and arrangement of the turns on the core 10 any connection pattern for the connections of the finished module. For this purpose, it is sufficient that the computer 37 of the device according to FIG. 1 has the winding device 30 controls depending on the connection data fed in, in order to produce a winding pattern on the core 10, which connections in the finished module according to the Connection data results. Such programming of a computer or a data processing system is easily feasible based on the above explanations .

After the description of the method according to the invention for producing the connection module 50, an explanation follows of typical applications of the module with reference to FIGS. 1 to 14.
