Definitions
- the invention relates to a transformer with a wound bobbin, with opposite coil flanges and with at least one on one of the coil flanges arranged eyelet strip to which the wire ends are led out of the winding.
- connection eyelet strips are provided on both flanges (DE-U-71 32 264). In these cases, wrapping can be done without tape. Connection eyelets on both flanges are not always possible. From FR-A-924 141 it is stretched over tensioning hooks provided on opposite flanges. However, this measure cannot be automated.
- deflection pins are arranged on the edge of the coil flange, which is opposite the edge of the coil flange provided with a connecting eyelet strip over the surface of the winding, that connecting wire ends of the winding are wound on these deflection pins under tension, the last of which Windings are located on the winding side facing the deflecting pins and that these connecting wire ends are led over from the deflecting pins to the connecting eyes on the terminal strip and that guideways for wire guides are provided around the deflecting pins.
- the deflection pins With the aid of the deflection pins, it is possible to initially place the connecting wire ends of windings, the last turns of which are wound away from the connecting eyelet, around the deflection pins and thus to fix the winding without the use of adhesive tape.
- the wire ends are then guided freely from the deflection pin to the connection lugs and soldered there.
- the wire guides can move around the individual deflection pins and thus automatically lead the winding ends to the connection lugs. Any intermediate work to fix the wrap is no longer necessary.
- the drawing shows a plan view of a transformer with a winding body and a transformer winding, in which the wire ends are first stretched around deflection pins and then guided to the connection lugs.
- the coil former 1 of a transformer 3 is provided with a winding 7 between the flanges 5. This winding consists of several partial windings, the connecting wire ends 9 of which are guided to the connecting lugs 11 on a connecting lug strip 13.
- the terminal block 13 is fastened to a flange edge part 15 arranged in the top view of the transformer. Seen over the surface 17 of the winding 7, this flange edge part 15 is opposite a flange edge part 19 of the other flange 5. Deflection pins 21 are arranged on the flange edge part 19, upright in the drawing. These deflection pins 21 are surrounded by guideways 23 for a wire guide, which is not shown.
- connection ends 9 are glued with an adhesive tape before they are led to the connection lugs 11, so that the winding does not become loose. After sticking, which is usually done by hand, the connecting wire ends 9 are then passed over to the connecting eyes 11.
- the deflection pins 21 replace this previously usual masking process.
- the wire guide leads the individual connecting wire ends 9 from the windings, the last turns of which are wound onto the deflection pins 21, possibly already spread out, initially tensioned after the completion of the winding process of the individual winding around one of the deflection pins 21. The winding is now fixed and can no longer loosen. The end of the wire is then pulled across the winding 7 to the eyelet 11 and fixed or soldered there.
