Device for the production of wire bridges, in particular for circuit boards

The innovation relates to a device for the production of wire bridges and connecting wires with stripped, right angles Bent wire ends, especially for circuit boards with extensive cable runs.

There are devices for the production of such wire sections known that a cutting of the sections into an adjustable length, as well as a stripping of the wire ends fully automatically carry out. In order to easily insert such sections as wire bridges or connecting wires in circuit board However, it is advantageous to bend the stripped wire ends at right angles, with wire bridges both The stripped wire ends should point approximately in one direction. The necessary bending over of the wire ends is often done by hand with the help of pliers, as a additional device or an extension of the cutting device, in order to bend the wire ends in an additional work step, very complex and prone to failure Requires vending machine.

These specialist parts can be avoided if according to the innovation in, the device side by side in relation to the to be introduced, insulated wire cutting knife for cutting the wire, stripping and stripping at the distance of the piece of wire to be stripped Bending knife for stripping and bending the stripped wire ends, as well as holding or clamping devices for holding of the lead wire are arranged during the cutting, stripping and bending of the wire ends. This will it is possible to create the desired wire sections with bent, abiso ^ · manufacture lined wire ends.

In the drawing, an embodiment of the innovation is shown.

Fig. 1 shows a wire section as it is in the known Devices is manufactured,

2 shows a wire bridge introduced into a printed circuit,

Pig. 3 the construction principle of a device according to the innovation and

Pig. 4- the device according to Pig. 3 in another job position.

In order to be able to easily insert a wire section provided with an insulation 1 into a printed circuit board 2, it is advantageous to bend the wire ends 3 at right angles, with both wire ends in one wire bridge Must be bent in the direction in order to enable insertion into the wire breaks 4 of the circuit board 2 provided for this purpose. The electrical connection with cable runs 2 ' this circuit board 2 can then be done in a known manner by dip soldering.

To produce the wire sections, a wire wound into a roll is used, which is pre-tinned and from is surrounded by isolation. One end 5 of this jumper wire is inserted into a guiding and pulling device (not shown) inserted, which the jumper wire end in the direction of the Arrow 6 in Pig. 3 between two cutting knives 7 and 8 and a two-part clamping device 9 »10. While a cutting knife 7 and the part 9 of the clamping device is rigidly attached to an upper support 11, the second Cutting knife 8 is rigidly attached to a lower stamping device 12. The second part 10 of the clamping device is in the lower support 12 mounted in such a way that it can be pressed into the lower support, a spring 13 ensuring that this Part 10 of the clamping device in the Pig. 3 is pressed the initial position defined by stops. Immediately in front of the clamping device is still on the

■ lower support 12 a stripping bending knife 14 rigidly attached, which has a hat on the side facing the clamping device. The sut "width is slightly wider than the diameter of the conductor of the wire to be stripped. ;

If the wire end is 5 up to the preset length in the direction of the gate is introduced »so the lower beam 12 is against the upper bracket 11 is pressed. The clamping device jams here 9> 10 the wire end 5 firmly, with protruding Cut edges 16 of the clamping device into the insulation * At the same time, the wire end 5 is cut off by the cutting knives 7, 8. When further merging the questions 11, then the stripping bender strips the insulation; 17 of wire end 18 to be stripped and bends it at the same time at right angles.

A similar structure of the clamping device 9 »10 and the stripping bending knife can be used at the end of the inserted wire end be arranged in mirror image if a wire bridge according to Pig. 2 is to be produced in one operation. Here Instead of the cutting knives 7, 8, a »stop can also be provided.
