Definitions

the invention relates to a multi-part winding device, consisting of at least one inner and an outer shape and controlled feed pins, for winding saddle spools consisting of at least one winding strand for deflecting units of color picture tubes.
the saddle coils of a deflection unit are used to generate the magnetic fields that deflect the electron beams in color picture tubes.
Such saddle spools are named after their saddle-shaped shape and are designed in such a way that they are self-converging.
Self-converged saturated coils do not need auxiliary currents to achieve convergence. Convergence is achieved when the accelerated electrons of all three electron beams meet precisely at each point on the screen of the color picture tube during their deflection in the vertical and horizontal directions due to the change in magnetic fields over time.
the winding device consists of at least two parts that can be assembled, the inner shape and the outer shape.
the inner shape bears the outwardly curved negative inner contour and the outer shape the inwardly curved negative outer contour of the saddle coil to be wrapped between the inner shape and the outer shape.
the circulation of the individual winding wires in the coil determines the shape and strength of the magnetic field generated by the coil. Even a slight deviation of the wire path from the SoLL value influences the magnetic field and thus the deflection of the electron beams. This is noticeable as a convergence error on the screen.
the prerequisite for a usable winding technology is therefore good reproducibility of the position of the individual wires in the saddle spool.
the wire lays differently on the existing turns depending on the nature of the wire insulation.
the mechanical properties of the wire such as the conductivity, hardness of the wire or surface quality of the wedge shape, are not always sufficiently constant. you will be For example, significantly influenced by temperature and humidity.
a disadvantage of this known technique are the higher costs, determined by the precise manufacture of the cuff, and the long winding times.
FIG. 1 shows a perspective view of a saddle spool wound with the device according to the invention.
the winding strands 2 of the saddle coil run along the steps of the inner shape of the winding device (not shown in FIG. 1); the winding height 11, that is R a -R i , the winding strands increases as a result of the steps 1, as can be seen from FIG. 2.
the course of the steps is such that with a fixed azimuth ⁇ the radius R increases continuously with increasing Z and at constant Z the radius increases gradually with increasing ⁇ and decreases again gradually for ⁇ > 90 0 .
the cross section of the saddle spool shown in FIG. 2 is also indicated in FIG. 1 by dotted lines. Further cross sections perpendicular to the course of the winding strands would reveal corresponding gradations.
the gradation along the course of the winding strands is not the same across all areas. The gradation can disappear at points where the direction of the winding strands changes significantly. This is mainly the case where the winding wire wraps around the pins inserted during winding, so the position of the wire is already defined with sufficient accuracy by the winding pins. So that the saddle spool can be removed from the device without disturbing the steps, the finished saddle spool is lifted from the inner shape in the Z direction.
the Z direction is the direction paraLLeL to the main axis of the color picture tube.
the steps 1 of the inner part 5 of the device shown in a small detail in FIG. 3 in a spatial representation have grading surfaces 3 and graded surfaces 4 which are approximately perpendicular to the neighboring grading surfaces 3.
the winding strands 2 form-fit against the steps during winding.
FIGS. 5 and 6 show two cross sections through the device for winding satin spools, FIG. 5 showing the section CD from FIG. 6 and FIG. 6 the section AB from FIG. 5.
the wire forming the saddle coil is in the winding space 8 between the inner mold 5 and the outer form 6 wrapped in it.
the inner and outer parts are held together by means of the connecting pin 10 via the fastening plate 9.
the cover 7 is removed and, after the connecting pin 10 has been loosened, the saddle spool together with the inner mold 5 is removed from the outer mold 6. Then the saddle spools and the stepped inner mold 5 are separated from one another in the Z direction.
FIG. 7 The perspective views of the outer shape in FIG. 7 and the inner shape in FIG. 8 serve to improve the clarity in addition to FIGS. 5 and 6.
bobbin winding spools are to be wound with high accuracy, good reproducibility and little waste.
the inner shape of the winding device is graduated in contrast to the known inner shapes. This ensures a precise position of the wires and increases reproducibility in production.
the wire When using the winding device according to the invention, the wire is wound into a device serving as a winding form and then baked.
the contour of the wrap shape is no longer continuous, but is stepped. It consists of a rotationally symmetrical outer part, on which the wire can slide well, and a stepped inner shape, from which the wire is held in the positions defined by the steps.
the result is a well reproducible, self-converging, self-supporting saddle coil with a rotationally symmetrical outer and stepped inner contour.
the graduated inner part is designed according to the requirements of optimal convergence and maximum reproducibility.
