Adjustment and tuning device for printed coils

The innovation relates to an adjustment and tuning device for printed spools "

It is known to bring the Atgleich printed coil a disc of induktivitätserhöhendem or induktivitätsverminderndem material in the region of the coil, "- Furthermore, it is known plunger variometer, Z ₀ B ₀ with to provide an iron and a metal core, so as to provide greater To achieve variation »

The innovation is based on the task on the basis of the known arrangement to find designs that are suitable for the technology of printed circuit boards «

The innovation is characterized in that a balancing disk is made inductive increasing and a balancing disc made of inductive reducing Material is provided, and that the position of these disks to the coil surface is changed at the same time «

Embodiments of balancing and tuning devices according to Innovations are described below with reference to Figures 1 to 5 »

FIG. 1 shows a balancing device with a screw spindle ₉

Figure 2 shows an arrangement in which the adjustment by rotating a Trimmseube can be done in the range of approx. 9o °,

FIG. 3 shows an adjusting and tuning device in which the adjusting disks are moved in opposite directions to each other.

FIG. 4 shows an adjustment and tuning device ₉ in which the adjustment disks are fastened to one another and are moved in the same direction, and FIG

FIG. 5 shows a balancing and tuning device in which, by means of a swivel device, the angle that the balancing disks close of the printed coil form, be changed «,

In Figure 1, 1 is the card of the printed circuit _s on which, among other things, the coil 2 is located »A threaded socket 3 is embedded in the card 1, in which the screw spindle 4 can be rotated. The spindle 4 and the socket 3 can, each made according to the requirements, from metal or plastic ,, at the head of the spindle 4 to ₀ ZOB is a disc 6 from induktivitätserhöhendem material (HF-iron) and the nut 5 is a disc 7 from induktivitätsverminderndem material (brass) "with the nut 5 the stroke required for the adjustment can be set. "After this, a safeguard against rotation must be provided by known means" The inductance of the coil 2

thereof alhängig to what extent the influence of the disc 6 or the plate 7 predominates in the coil field "is the influence of the disk 7 (brass) is greater than that of the disk 6 (HF-iron), so causing the latter to concentrate the stray field of the coil 2 ₀

In the exemplary embodiment according to FIG. 2, 1 is located on the card One wing 6 and 7 on both sides, which are controlled by the adjustment screw 4. can be swiveled by about 9o «The inductance again depends on whether the wing 6 (HF iron) or the wing 7 (brass) mainly influenced the field of the coil 2

FIGS. 3 and 4 illustrate how the inductance 2 printed on the card 1 can be achieved by moving the adjusting disks 6 and 7 perpendicular to the coil axis. The arrangement according to FIG For this purpose the panes B and 7 in Figure 4 _{are to be connected to each other at the point 8 Z 0} B ₀ by cementing »Which of the two execution forms η is to be preferred depends on the overall construction of the device“ The same also applies to the drive "This can be done Z ₀ B ₀ by a cable drive or via toothed racks"

The embodiment of Figure 5 provides a V-shaped arrangement of the Ableibhhscheibe 6 and 7, for this one is around the axis 8 pivotable bracket 9 provided, the top view of which represented a sector of a circle. which is in engagement with the pinion Io "By pivoting the holding

tion 9 around the axis 8 attached to the card 1 change the angles, which form the disc 6 (HF iron) and the disc 7 (brass) with the printed coil 2.

The exemplary embodiments according to FIGS. 3 to 5 are also suitable as a tuning device, with several similar units with each other can be coupled »The frequency response», as well as the equal and Parallel operation can be influenced by a suitable shape of the adjustment disks 6 and 7 »
