Definitions
- the invention relates to a voltage divider according to the preamble of the main claim.
- the voltage divider according to the invention with the characterizing features of the main claim has the advantage that a certain equipotential line can be selected on the pickup electrode of the tap by moving the change required for the adjustment in the second resistance area belonging to the tap, without the actual one thereby Voltage divider resistance and its potential distribution must be changed significantly.
- a particularly advantageous type of change applied to the second resistance area for the purpose of comparison results from sub-claim 2. Further advantageous developments of the invention result from the further subclaims 3 to 12.
- dependent claim 13 provides a second advantageous solution to the comparison problem stood with a single coherent voltage divider, which is also used as a tap.
- FIG. 1 shows the basic variant of a voltage divider according to the invention implemented in thick-film technology in a top view
- FIG. 2 shows the equivalent circuit diagram of the voltage divider shown in FIG. 1, Figure 3 to Figure 8 further variants of voltage dividers according to the invention executed in thick-film technology in plan view.
- the voltage divider shown in Figures 1 and 2 contains a current-carrying ohmic voltage divider resistor R. (Fig. 2), which consists of a single coherent, layered design of the first resistance layer 10, a connecting conductor 11 serving for current supply and a connecting conductor 12 serving for current dissipation , wherein the connecting conductors 11 and 12 are formed as conductor tracks (Fig. 1).
- the first resistance region 10 forms a rectangular region, the length of which is greater than the width.
- the connecting conductors 11 and 12 are attached to the narrow sides of this rectangular region and overlap with the first resistance region 10 along these narrow sides.
- a tap is also provided for tapping off the desired divider voltage.
- This tap consists of a second resistance region 13, which is embodied in layer technology, and of a removal electrode 1 h attached to it, which is designed as a conductor track.
- the two resistance regions 10 and 13 abut one another in a region 15 which is located on one of the two long sides of the resistance layer 10 in such a way that good electrical contact is established in this region 15 between these two resistance regions 10 and 13.
- first laser or sandblast cut is made in the second resistance region 13 16 and a second laser or sandblast cut 17 are introduced.
- the two cuts 16 and 17 run parallel to the long side of the first resistance region 10, that is to say cut the equipotential lines formed during operation of the voltage divider.
- the two cuts 16 and 17 are carried out until the potential at the pick-up electrode 1 4 of the tap has reached the desired value.
- the effective value of the resistance R 1 is influenced relatively strongly by the adjustment. If this effect interferes, the material of the second resistance region 13 is selected with a higher resistance than the material of the first resistance region 10, so that the effective voltage divider resistance formed by the first resistance region 10 and its potential distribution are not significantly changed by the adjustment.
- FIG. 3 shows a second exemplary embodiment of a voltage divider according to the invention, in which one tap 13, 14 and one tap 13, 14 are attached to one of the two long sides of the first resistance region 10 and two taps 13, 14 to the other long side.
- the adjustment is carried out in the same way as in the exemplary embodiment according to FIGS. 1 and 2.
- the first resistance region 10, as in the exemplary embodiments according to FIGS. 1 and 3, is formed as a rectangular rectangle.
- the second resistance region 13, like the first resistance region 10, is designed in the form of a strip.
- the second resistance area 13 runs parallel to the first resistance region 10 and is connected to the first resistance region 10 via a contact zone 15.
- the contact zone 15 extends over the entire length of the first resistance region 10.
- a laser or sandblast cut 16 is provided in the second resistance region 13, which runs parallel to the longitudinal direction of the two resistance regions 10, 13.
- the removal electrode 1 4 for the divider voltage to be tapped is designed differently in the exemplary embodiments according to FIGS. 4 to 6.
- the depth of the laser cut 16 mainly determines the level of the divider voltage to be picked up at the removal electrode 14.
- the divider voltage tapped at the take-off electrode 14 can be between 0 and 100% of the voltage applied to the connecting conductors 11 and 12.
- the different selection of the geometry of the removal electrode 14 enables the adjustment characteristic curve to be adapted to the respective requirement.
- the exemplary embodiment according to FIG. 7 is used to generate arbitrarily selectable, monotonous adjustment characteristic curves and to compensate the important linearities of a circuit.
- This exemplary embodiment differs from the exemplary embodiments according to FIGS. 4 to 6 in that the first resistance region 10 forming the ohmic voltage divider resistor R 1 deviates from the range of its first connecting conductor 11 widened to the area of its second connecting conductor 12.
- the limitation of both resistance areas 10 and 13 is linear in the contact zone 15 and the second resistance area 13 is strip-shaped.
- the laser cut 16 runs in the second counter Stand area 13 parallel to its longitudinal direction.
- the second resistance region 13 extends over the full length of the first resistance region 10 and at the upper end a little further, a voltage between 0 and 100% of the voltage between the connecting conductors 11 and 12 can also be picked up at the take-off electrode 14 .
- the entire voltage divider consists of a single resistance layer 110.
- This resistance layer 110 also forms the current-carrying ohmic voltage divider resistor R .. and tap 114.
- the resistance layer 110 has one for power supply and one for power dissipation, each with a connecting conductor 111, 112 connected area.
- the connecting conductors 111, 112 can be designed as bond wires.
- a cut 116 is made in the coherent resistance layer 110, which runs between the part of the layer forming the tap 114 and the region of this layer which serves to supply or discharge current, and so on is carried far until the potential at tap 1 14 has reached the desired value.
- the divider voltage tapped at the tap 114 can also be between 0 and 100% of the voltage applied to the connecting conductors 111 and 112.
- the invention is not limited to the exemplary embodiments described with reference to the drawing.
- the two resistance regions 10 and 13 can form a single, coherent region if the two regions 10 and 13 consist of the same material. In this case, the contact zone 15 can be omitted.

Abstract
On propose un diviseur de tension en technique à couches minces ou épaisses ajustable avec une résistance ohmique traversée par un courant et au moins un moyen de prélèvement de la tension partielle. La résistance ohmique contient une première zone de résistance (10) de diviseur de tension qui contient une zone d'arrivée de courant et une zone de sortie de courant munies chacune d'un conducteur (11, 12). Le dispositif de prélèvement est constitué par une deuxième zone de résistance (13) située entre les deux zones et connectée avec la première zone de résistance (10) ainsi que par une électrode de prélèvement (14). Dans cette deuxième zone de résistance (13) on aménage deux fentes (16, 17) qui traversent les lignes équipotentielles qui se forment lors du fonctionnement du diviseur et on les prolonge suffisamment pour que sur l'électrode (14) du dispositif de prélèvement le potentiel ait la valeur désirée (Fig. 1).We propose a voltage divider using an adjustable thin or thick film technique with an ohmic resistance through which a current flows and at least one means for sampling the partial voltage. The ohmic resistor contains a first voltage divider resistance region (10) which contains a current input region and a current output region each provided with a conductor (11, 12). The sampling device is constituted by a second resistance zone (13) located between the two zones and connected with the first resistance zone (10) as well as by a sampling electrode (14). In this second resistance zone (13) two slots (16, 17) are provided which cross the equipotential lines which are formed during the operation of the divider and they are extended sufficiently so that on the electrode (14) of the sampling device the potential has the desired value (Fig. 1).
