Description

[Technical Field]

[0001] The present invention relates to a measurement value detection device for an inductive sensor arrangement. The invention also relates to an inductive sensor arrangement comprising at least one such measurement value detection device. [Background technology]

[0002] The prior art discloses inductive sensor devices that include a measurement value detection device having at least one exciter structure and at least one receiver structure, and at least one coupling device, also referred to as a target. Furthermore, the at least one exciter structure includes at least one excitation coil. The at least one coupling device includes at least one conductive coupling element. The at least one receiver structure includes at least one receiver coil, but typically two receiver coils. When a high-frequency current is passed through the at least one excitation coil, an alternating magnetic field is generated, which induces eddy currents in the at least one coupling device. In this case, the inductive coupling between the at least one excitation coil and the at least one receiver coil depends on the position of the corresponding coupling device. The voltage signal induced in the at least one receiver coil allows the actual position of the coupling device, and thus the actual position of the object whose motion is to be detected, to be estimated.

[0003] German Patent Application Publication No. 10 2020206396 discloses an inductive angle sensor comprising an inductive target device with k-fold symmetry, a first pickup coil device with k-fold symmetry, and a second pickup coil device with k-fold symmetry. A combination device is configured to combine signals from the first pickup coil device and the second pickup coil device and, based on this, calculate an angle-error-compensated rotation angle. The individual pickup coils of the first and second pickup coil devices are offset so that they are rotated relative to each other by a geometric offset angle about a rotation axis. Additionally, the entire first pickup coil device is rotated relative to the entire second pickup coil device by the geometric offset angle about the rotation axis. In one envisaged embodiment, the first and second pickup coil devices are galvanically connected to each other to form one or more individual pickup coil pairs, in which each individual pickup coil of the first pickup coil device is connected in a series circuit or in a parallel circuit to a respective individual pickup coil of the second pickup coil device, offset by a geometric offset angle with respect to the first pickup coil device, and the combining device is configured to determine an angle-error-compensated rotation angle between the stator and the rotor based on a combination of the combined individual pickup coil signals of the one or more individual pickup coil pairs.

[0004] [Patent Document 1] German Patent Application Publication No. 102020206396 Summary of the Invention [Problem to be solved by the invention]

[0005] Disclosure of the Invention A measurement value detection device for an inductive sensor device having the features of independent claim 1 has the advantage that efficient arrangement of a connection structure between the windings of a receiving coil inside the corresponding receiving structure saves space, increases the amplitude of the induced voltage, and simultaneously reduces the angular error of the measurement value detection device. This early termination of the loop structure of the receiving coil allows for a series connection of at least two windings of the receiving coil and / or a reversal of the winding current direction. Furthermore, a series connection inside the receiving structure allows for a higher effective voltage to be induced in the receiving coil than would be the case with a series connection outside the receiving structure. The increased induced voltage results in a better signal-to-noise ratio and improved EMC robustness (EMC). Furthermore, this allows for the use of lower-cost semiconductor amplifiers with a lower amplification factor. The term "receiving structure" here should be understood to mean the arrangement of the connection structure in the plane subtended by the receiving structure. If the receiving structure extends, for example, from y_min to y_max in a first direction y and from x_min to x_max in a second direction x, the connecting structure is located between y_min and y_max or between x_min and x_max, where the shape and configuration of the connecting structure depends on the respective parameters. [Means for solving the problem]

[0006] Embodiments of the present invention provide a measurement value detection device for an inductive sensor device, comprising a circuit carrier including at least one receiving structure. The at least one receiving structure includes at least one receiving coil having at least two windings. Each winding of the at least one receiving coil has two loop structures each having a plurality of loop sections and is formed on at least two planes of the circuit carrier. The sections of the individual loop structures arranged on different planes of the circuit carrier are electrically connected to each other via through contacts. The loop sections of the two loop structures of the individual windings have opposite current flow directions. The loop structures of the at least two electrically series-connected windings of the at least one receiving coil are arranged offset from each other by a set distance. In this case, the ends of the individual loop structures of the at least two windings of the at least one receiving coil are connected to each other in the end region of the corresponding receiving structure via at least one connecting structure, respectively, so as to electrically connect the at least two windings in series and / or to reverse the current flow direction within one of the at least two windings.

[0007] Furthermore, an inductive sensor device for detecting the movement of a moving object is proposed, comprising at least one coupling device and a measurement value detection device as described above. Here, the at least one coupling device or measurement value detection device is coupled to the moving object whose movement is to be detected. At least one exciter structure is arranged on the circuit carrier of the measurement value detection device. The at least one exciter structure is coupled to at least one evaluation and control circuit, which applies a periodic AC signal to the at least one exciter structure during operation. The at least one coupling device is configured to affect an inductive coupling between the at least one exciter structure and at least one receiving structure of the measurement value detection device. The at least one evaluation and control unit is configured to receive and evaluate the signal induced in the at least one receiving structure and to determine the actual position of the moving coupling device relative to the at least one receiving structure and / or the actual position of the moving object.

[0008] Inductive sensor devices can be configured, for example, as linear displacement sensors, in which a moving object's translational movement along a motion axis is to be detected, or as rotation angle sensors or rotor position sensors, in which a moving object's rotational movement around a rotation axis is to be detected. In inductive rotation sensors, the measurement value detection device can preferably have a space-saving "C" shape that can be inserted onto a shaft. This simplifies the manufacturing concept for integrating the inductive sensor device. The coil layout for such a measurement value detection device can be calculated in Cartesian coordinates by a coordinate transformation of the coil layout of the measurement value detection device for an inductive linear displacement sensor, provided that the origin (0,0) is appropriately selected.

[0009] An evaluation and control unit can be understood in this context as an electrical module or circuit that prepares, processes or evaluates the detected sensor signals. Preferably, the evaluation and control unit can be configured as an ASIC module (ASIC: Application Specific Integrated Circuit). The evaluation and control unit can have at least one interface that can be configured by hardware and / or software. In the case of a hardware configuration, the interface can be, for example, part of an ASIC module. However, the interface can also be a dedicated integrated circuit or can at least partially consist of discrete components. In the case of a software configuration, the interface can be, for example, a software module that is provided on a microcontroller in addition to other software modules.

[0010] An exciter structure can then be understood to be an excitation coil with a predetermined number of turns, which transmits an AC signal generated by the evaluation and control unit.

[0011] Advantageous improvements of the measurement value detection device for an inductive sensor arrangement according to independent claim 1 and of the inductive sensor arrangement according to independent claim 14 are realized by the measures and developments set forth in the respective dependent claims.

[0012] Particularly advantageously, the number of connection structures can be based on the number of windings of the at least one receiving coil, so that an electrical series circuit of the windings of the at least one receiving coil can be systematically realized.

[0013] In an advantageous configuration of the measurement value detection device, at least one connection structure may include a through contact that interconnects two individual loop structures, each consisting of two windings or a common winding of one of at least two windings, located in different planes. In this case, the two individual loop structures may terminate at the through contact before the corresponding end of the receiving structure. This allows the two loop structures to terminate "early," i.e., before reaching one end of the receiving structure. Preferably, the through contact can be located in the region of the intersection of two individual loop structures, each consisting of two windings or a common winding of one of at least two windings, located in different planes. Alternatively, at least one connection structure may include a conductor track piece that is connected to the ends of two individual loop structures, each consisting of two windings or a common winding of one of at least two windings, located in the same plane, and interconnects these windings. If the windings to be connected "terminate" in the same plane of the printed circuit board, no through contact is necessary; a conductor track piece is sufficient. In this case, the two loop structures to be connected can be formed "early," i.e., terminated before reaching the end of the receiving structure, thereby leaving space inside the receiving structure for the application of the conductor track pieces of the connection structure. Alternatively, at least one connection structure can include a through contact and at least one conductor track piece in one or both of two planes and connect two individual loop structures, each consisting of two windings or a common winding of one of at least two windings, arranged in different planes. Alternative implementations of the connection structure allow these alternative implementations to be easily adapted to the structural requirements of the receiving structure. When the connection structure connects loop structures to two different windings of the receiving coil, an electrical series connection of the two windings can be achieved, which preferably also results in a current flow direction for the loop structures of the two windings connected in this way. When the connection structure connects loop structures of a common winding or the same winding of the receiving coil, a reversal of the current flow direction within this winding can be achieved.The unambiguous definition of all current directions in the receiving coil depends on the polarity of the measurement of the induced signal, so all current reversals can be considered equivalent and depend only on the definition.

[0014] In another advantageous configuration of the measurement value detection device, the through contact can be connected to an end of one of the two loop structures in one plane and to at least one conductor track piece in the other plane, which can be connected to the end of the other of the two loop structures at a contact point. In this case, the position of the through contact can be shifted along the corresponding loop structure and can be terminated before reaching the end of the receiving structure, provided that this does not result in a short circuit or a violation of design rules. Violation of design rules is understood to mean, for example, that the distance from the conductor track to the through contact and / or the distance between the conductor tracks is minimized. Alternatively, a first conductor track piece can be connected to the through contact in one plane and to the end of one of the loop structures at a contact point, and a second conductor track piece can be connected to the through contact in the other plane and to the end of the other of the two loop structures at a contact point.

[0015] In another advantageous configuration of the measurement value detection device, the loop sections of the two loop structures can each be periodically repeated. In this case, one complete loop section cycle corresponds to a sine, square or triangular waveform, and the number of periodically repeated loop sections can be considered to define the periodicity of the receiving structure. Of course, the periodically repeated loop sections can also have other suitable shapes or mixed shapes. Due to the early termination, the shape of the loop sections of the loop structure at the end of the receiving structure can be different from the shape of the repeated loop sections of the loop structure in the remaining area of the receiving structure.

[0016] In another advantageous configuration of the measurement value detection device, the individual loop structure sections arranged in different planes of the circuit carrier can correspond, for example, to ½, ¼ or ⅛ of a period of the repeating loop sections.

[0017] In a further advantageous configuration of the measurement value detection device, the distance between adjacent loop structures of at least one receiving structure can be based on the number of receiving structures, the number of receiving coils, the number of windings of the at least one receiving coil, and the period of the at least one receiving structure. In this case, the distances between the loop structures of the windings of at least one receiving coil of the same receiving structure can be of equal magnitude. Equal distances allow optimal utilization of the available structural space in terms of maximizing the number of windings and at the same time avoid design rule violations. Preferably, the loop structures of the individual windings of the at least one receiving coil can be formed to be approximately identical. Alternatively, the distances between the loop structures of these windings can be different, especially if the at least one receiving coil has three or more windings.

[0018] In another advantageous configuration of the measurement value detection device, the loop structures of the windings of several receiver coils can be arranged alternately along the receiving structure. This means that in the case of two receiver coils, the loop structure of the first receiver coil is arranged after the loop structure of the second receiver coil, followed by the loop structure of the first receiver coil, and so on. Alternatively, the loop structures of the windings of several receiver coils can be arranged in groups following the receiver coils along the receiving structure. This means that, with three windings per receiver coil, first three loop structures of the individual windings of the first receiver coil are arranged, then three loop structures of the individual windings of the second receiver coil, followed by three loop structures of the individual windings of the first receiver coil, etc.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Embodiments of the invention 1 to 11, the illustrated embodiment of a measurement value detection device 10 according to the invention for an inductive sensor device 1 comprises a circuit carrier 11 with at least one receiving structure 14, which in turn comprises at least one receiving coil 16 with at least two windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3. Each winding 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of the at least one receiving coil 16 comprises two loop structures 18A, 18B each with a plurality of loop sections SA, which are formed in at least two planes of the circuit carrier 11. The sections of the individual loop structures 18A, 18B arranged in different planes of the circuit carrier 11 are electrically connected to one another via through contacts DK. The loop sections SA of the two loop structures 18A, 18B of each individual winding 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 have mutually opposite current flow directions. The loop structures 18A, 18B of at least two electrically series-connected windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of at least one receiving coil 16 are arranged offset from each other by a set distance. In this case, the ends of the individual loop structures 18A, 18B of at least two windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of at least one receiving coil 16 are connected to each other in the end regions 14.1, 14.2 of the corresponding receiving structure 14 via at least one connecting structure 20, respectively, so as to result in an electrical series connection of the at least two windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 and / or a reversal of the current direction in one of the at least two windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3.

[0022] The number of connecting structures 20 is based on the number of windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of the at least one receiving coil 16. As can be further seen from FIGS. 1 to 10 , the loop sections SA of the two loop structures 18A, 18B in the illustrated embodiment are periodically repeated. In this case, one complete cycle of the periodically repeated loop section SA corresponds to a sine or cosine waveform, respectively. Alternatively, the periodically repeated loop section SA may correspond to a square or triangular waveform. Furthermore, the sections of the individual loop structures 18A, 18B located on different planes of the circuit support 11 correspond to half a cycle of the repeated loop section SA. Here, through contacts DK connecting the sections of the individual loop structures 18A, 18B located on the lower plane of the circuit support 11 to the sections of the individual loop structures 18A, 18B located on the upper plane of the circuit support 11 are located at the upper and lower edges of the diagram of the receiving structure 14, respectively. In the illustrated embodiment of the measurement value detection device 10, the two loop structures 18A, 18B of the at least one receiver coil 16 are arranged offset by 180° with respect to one another, the current flowing in the first loop structure 18A of the at least two electrically series-connected windings 1W1, 1W2, 1W3, 2W3, 2W1, 2W2, 2W3 of the at least one receiver coil 16 running in the positive x-direction (here from left to right) and in the second loop structure 18A of the at least two electrically series-connected windings 1W1, 1W2, 1W3, 2W3, 2W1, 2W2, 2W3 of the at least one receiver coil 16 running in the negative x-direction (here from right to left). Two loop structures 1A, 18B having mutually opposite running directions and arranged offset from each other by 1 / 2 period or 180° along the motion path BB surround respective faces having different area normals between the first loop structure 18A and the second loop structure 18B of at least two windings 1W1, 1W2, 1W3, 2W3, 2W1, 2W2, 2W3 of at least one receiving coil 16.Depending on the periodicity of the windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of the at least one receiving coil 16, a corresponding number of plane pairs are surrounded between the two loop structures 18A, 18B of the at least two electrically series-connected windings W1, W2. Alternatively, the sections of the individual loop structures 18A, 18B arranged in different planes of the circuit support 11 may correspond to a quarter or eighth of a period. Due to the early termination, the shape of the loop sections SA of the loop structures 18A, 18B at the end of the receiving structure 14 can be different from the shape of the repeated loop sections SA of the loop structures 18A, 18B in the remaining area of the receiving structure 14.

[0023] 1 to 11, the distance between adjacent loop structures 18A, 18B of the at least one receiving structure 14 is based on the number of receiving structures 14, the number of receiving coils 16, the number of windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of the at least one receiving coil 16 and the period of the at least one receiving structure 14, and is therefore different in each of the different illustrated embodiments of the measurement value detection device 10. In the illustrated embodiments of the measurement value detection device 10, the distances from the windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of the at least one receiving coil 16 of the same receiving structure 14 to the loop structures 18A, 18B are of equal magnitude. Furthermore, loop structures 18A, 18B of windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 comprising a plurality of receiving coils 16 are arranged in groups following the receiving coils 16 along the receiving structure portion 14.

[0024] As can be further seen from FIGS. 1 and 6 , the inductive sensor devices 1 are each configured as inductive linear displacement sensors in the illustrated embodiments and each include at least one coupling device 3 and a measurement value detection device 10 according to the invention for detecting the movement of a linearly moving object (not shown). In this case, the at least one coupling device 3 or the measurement value detection device 10 is coupled to a moving object (not shown), whose linear movement along a movement path BB is to be detected. At least one exciter structure 13 is arranged on a circuit carrier 11 of the measurement value detection device 10. The at least one exciter structure 13 is coupled to at least one evaluation and control circuit 12, which, during operation, applies a periodic AC signal to the at least one exciter structure 13. The at least one coupling device 3 includes an electrically conductive coupling element 3.1 and is configured to affect an inductive coupling between the at least one exciter structure 13 and at least one receiving structure 14 of the measurement value detection device 10. The at least one evaluation and control unit 12 is configured to receive and evaluate the signals induced at the at least one receiving structure 14 and to determine the current relative position of the movable coupling device 3 and / or the current position of the moving object with respect to the at least one receiving structure 14. As can further be seen from Figures 1 and 6, the receiving structure 14 extends in a first direction y from y_min to y_max and in a second direction x from x_min to x_max along the trajectory of movement B of the coupling device 3, with a corresponding plane extending between (y_max-y_min) and (x_max-x_min).

[0025] For the sake of clarity, the electrical connection of the at least one receiving coil 16 of the at least one receiving structure 14 to the evaluation and control unit 12 is not shown in Figures 1 to 11. This does not mean that the at least one receiving coil 16 is short-circuited. Of course, it is also possible to separate the at least one receiving coil 16 at a suitable location, for example at a through contact DK, and to lead it by an additional conductor to the evaluation and control unit 12, so that the evaluation of the induced signal can take place at this location.

[0026] 1 to 5, the inductive sensor device 1A according to the first embodiment of the present invention comprises a first embodiment of a measurement value detection device 10A including a receiving structure 14A and an exciter structure 13 including an excitation coil 13A with four windings, which in the illustrated first embodiment of the inductive sensor device 1A are arranged on two planes of the circuit carrier 11. This means that two windings are arranged on each plane of the circuit carrier 11. The receiving structure 14A comprises two receiving coils 16A and 16B, each with three windings 1W1, 1W2, 1W3, 2W1, 2W2, and 2W3, which are arranged on the two planes of the circuit carrier 11. In this case, the first receiving coil 16A forms a sine channel, and the second receiving coil 16B forms a cosine channel. Each of the windings 1W1, 1W2, 1W3, 2W1, 2W2, and 2W3 of the two receiving coils 16A and 16B has two loop structures 18A and 18B, each having five loop sections SA. In the illustrated embodiment, the loop sections SA of the two loop structures 18A and 18B of the individual windings 1W1, 1W2, 1W3, 2W1, 2W2, and 2W3 have a sinusoidal shape and opposite current directions. The loop structures 18A and 18B of the three electrically series-connected windings 1W1, 1W2, 1W3, 2W1, 2W2, and 2W3 of the two receiving coils 16A and 16B are offset from each other by a set distance. Here, the ends of the individual loop structures 18A, 18B of the three windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of the two receiving coils 16A, 16B are connected to each other via three connecting structure parts 20A1, 20B1, 20C1, 20D1, 20E1, 20F1, 20A2, 20B2, 20C2, 20D2, 20E2, 20F2, respectively, so as to result in an electrical series connection of the three windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3 of the two receiving coils 16A, 16B, and / or so as to result in a reversal of the current direction within one of the three windings 1W1, 1W2, 1W3, 2W1, 2W2, 2W3.

[0027] 1 to 3, the first connection structure 20A1, the second connection structure 20B1, and the third connection structure 20C1 of the first receiving coil 16A each include a through contact DK and two straight conductor track pieces 22 in two planes of the circuit carrier 11 at the first end 14.1 of the receiving structure 14A. In this case, the first connection structure 20A1 connects the second loop structure 18B of the third winding 1W3 of the first receiving coil 16A to the first loop structure 18A of the first winding 1W1 of the first receiving coil 16A. For this purpose, the straight conductor track piece 22 extending in the y direction, which is arranged in the upper plane of the circuit carrier 11 in the figure, is connected with a first end at a contact point 24 to the front end of the second loop structure 18B of the third winding 1W3 and with a second end to the through contact DK. A straight conductor track piece 22 extending in the y direction, located in the lower plane of the figure of the circuit carrier 11, is connected with a first end at a contact point 24 to the early end of the first loop structure 18A of the first winding 1W1 and with a second end to the through contact DK. A second connection structure 20B1 of the first receiving coil 16A connects the second loop structure 18B of the second winding 1W2 to the first loop structure 18A of the second winding 1W2. For this purpose, a straight conductor track piece 22 extending in the y direction, located in the upper plane of the figure of the circuit carrier 11, is connected with a first end at a contact point 24 to the early end of the second loop structure 18B of the second winding 1W2 and with a second end to the through contact DK. A straight conductor track piece 22 extending in the y direction, arranged in the plane below the diagram of the circuit carrier 11, is connected at a first end at a contact point 24 to the first loop structure 18A of the second winding 12 and at a second end to the through contact DK. A third connection structure 20C1 of the first receiving coil 16A connects the second loop structure 18B of the first winding 1W1 to the first loop structure 18A of the third winding 1W3.For this purpose, a straight conductor track piece 22 extending in the y direction and arranged in the upper plane of the drawing of the circuit carrier 11 is connected with a first end at a contact point 24 to an early end of the second loop structure 18B of the first winding 1W1 and with a second end connected to the through contact DK. A straight conductor track piece 22 extending in the y direction and arranged in the lower plane of the drawing of the circuit carrier 11 is connected with a first end at a contact point 24 to an early end of the first loop structure 18A of the third winding 1W3 and with a second end connected to the through contact DK.

[0028] 1 to 3, the first connecting structure 20A2 of the second receiving coil 16B includes a through contact DK at the first end 14.1 of the receiving structure 14A, which connects the individual loop structures 18A, 18B of the first winding 2W1 of the second receiving coil 16B, which are arranged on different planes of the circuit carrier 11. In this case, the second loop structure 18B of the first winding 2W1 of the second receiving coil 16B terminates at the through contact DK before the first end 14.1 of the receiving structure 14A. The first loop structure 18A of the first winding 2W1 of the second receiving coil 16B also terminates at the through contact DK before the first end 14.1 of the receiving structure 14A. The second connection structure 20B2 and the third connection structure 20C2 of the second receiver coil 16A each comprise a straight conductor track piece 22 extending in the y direction, which conductor track piece 22 is connected at a contact point 24 to an end of each of two individual loop structures 18A, 18B arranged in the same plane of the circuit carrier 11. For this purpose, the straight conductor track piece 22 extending in the y direction of the second connection structure 20B2 is connected at a first end at the contact point 24, which replaces the through contact DK, in the lower plane of the circuit carrier 11 to an end of the second loop structure 18B of the second winding 2W2 of the second receiver coil 16B, and at a second end at the contact point 24 to an end of the first loop structure 18A of the third winding 2W3 of the second receiver coil 16B.

The receiving structure 14B includes two receiving coils 16A, 16B, each with two windings 1W1, 1W2, 2W1, 2W2, arranged on two planes of the circuit carrier 11. In this case, the first receiving coil 16A forms a sine channel, and the second receiving coil 16B forms a cosine channel. Each winding 1W1, 1W2, 2W1, 2W2 of the two receiving coils 16A, 16B has two loop structures 18A, 18B, each with ten loop sections SA. In the illustrated embodiment, the loop sections SA of the two loop structures 18A, 18B of the individual windings 1W1, 1W2, 2W1, 2W2 have a sinusoidal shape and have mutually opposite current flow directions. The loop structures 18A, 18B of the two electrically series-connected windings 1W1, 1W2, 2W1, 2W2 of the two receiving coils 16A, 16B are arranged offset from each other by a set distance.

[0032] 6 to 8, the first and second connecting structures 20A1, 20B1 of the first receiving coil 16A each include a through contact DK at the first end 14.1 of the receiving structure 14B. Here, the first connecting structure 20A1 connects the second loop structure 18B of the second winding 1W2 of the first receiving coil 16A to the first loop structure 18A of the first winding 1W1 of the first receiving coil 16A. Thus, the second loop structure 18B of the second winding 1W2 and the first loop structure 18A of the first winding 1W1 of the first receiving coil 16A each terminate early at the through contact DK before the first end 14.1 of the receiving structure 14A. The second connecting structure 20B1 connects the second loop structure 18B of the first winding 1W1 of the first receiving coil 16A to the first loop structure 18A of the second winding 1W2 of the first receiving coil 16A, so that the second loop structure 18B of the first winding 16A and the first loop structure 18A of the second winding 1W2 of the first receiving coil 16A each terminate early in a through contact DK before the first end 14.1 of the receiving structure 14A.

[0033] 6 to 8, the first connection structure 20A2 and the second connection structure 20B2 of the second receiving coil 16B each comprise a straight conductor track piece 22 extending in the y direction at the first end 14.1 of the receiving structure 14B, which conductor track piece 22 is connected at a contact point 24 to an end of each of two individual loop structures 18A, 18B arranged in the same plane of the circuit carrier 11. For this purpose, the straight conductor track piece 22 extending in the y direction of the first connection structure 20A2 is connected at a first end at the contact point 24, which replaces the through contact DK, in the upper plane of the circuit carrier 11 to an end of the first loop structure 18A of the first winding 2W1 of the second receiving coil 16B, and at a second end at the contact point 24 to an end of the second loop structure 18B of the second winding 2W2 of the second receiving coil 16B. A straight conductor track piece 22 extending in the y-direction of the second connection structure part 20B2 is connected at a first end at a contact point 24 in the plane below the circuit support 11 to the end of the first loop structure 18A of the second winding 2W2 of the second receiving coil 16B, and at a second end at a contact point 24 replacing the second through contact DK to the end of the second loop structure 18B of the first winding 2W1 of the second receiving coil 16B.

For this purpose, the end of the first loop structure 18A arranged in the lower plane of the circuit carrier 11 is connected to the through contact DK and terminates early at the through contact DK. A linear conductor track piece 22 extending in the y direction, arranged in the plane above the circuit carrier 11, is connected at a first end at a contact point 24 to an early end of the second loop structure 18B of the first winding 1W1 of the first receiving coil 16A and at a second end to a through contact DK. Note that the through contact DK of the second loop structure 18B of the second winding 1W2 of the first receiving coil 16A is replaced by the contact point 24, so that the section of the second loop structure 18B that would normally extend in the plane above the circuit carrier 11 extends further in the plane below the circuit carrier 11. The fourth connecting structure 20D1 of the first receiving coil 16A therefore comprises only a straight conductor track 22 extending in the y direction at the second end 14.2 of the receiving structure 14B, connecting the second loop structure 18B of the second winding 1W2 of the first receiving coil 16A to the first loop structure 18A of the second winding 16W2 of the first receiving coil 16A.

In this case, the second loop structure 16B and the first loop structure 18A of the second winding 2W2 of the second receiving coil 16B each terminate early at the through contact DK before the second end 14.2 of the receiving structure 14B. Furthermore, the through contacts DK of the first loop structure 18A of the first winding 1W1 of the second receiving coil 16B are offset in the negative x-direction and negative y-direction along the first loop structure 18A from the upper edge of the receiving structure 14B, so that a section of the first loop structure 18A is located in the upper plane of the circuit support 11 rather than in the lower plane of the circuit support 11, with the contact points 24 being replaced by through contacts at the upper edge of the receiving structure 14B. Furthermore, the through contacts DK of the second loop structure 18B of the first winding 2W1 of the second receiving coil 16B are replaced by contact points 24 at the lower edge of the receiving structure 14B. The fourth connecting structure 20D2 of the second receiving coil 16B therefore comprises only a straight conductor track 22 extending in the y direction at the second end 14.2 of the receiving structure 14B, connecting the second loop structure 18B of the first winding 2W1 of the second receiving coil 16B to the first loop structure 18A of the first winding 2W1 of the second receiving coil 16B.

Each of the windings 1W1, 1W2, 2W1, and 2W2 of the two receiving coils 16A and 16B has two loop structures 18A and 18B, each forming one loop section SA. In the illustrated embodiment, the loop sections SA or the two loop structures 18A and 18B of the windings 1W1, 1W2, 2W1, and 2W2 each have a sinusoidal shape and opposite current directions. The loop structures 18A and 18B of the two electrically series-connected windings 1W1, 1W2, 2W1, and 2W2 of the two receiving coils 16A and 16B are offset from each other by a set distance.

In this case, at the upper edge of the receiving structure 14C, the through contact DK in the first loop structure 18A of the first winding 1W1 of the first receiving coil 16 is omitted, so that the end of the first loop structure 18A continues to be guided in the plane below the circuit carrier 11 rather than in the plane above it.

In this case, the through contact DK arranged on the upper edge of the receiving structure 14C is shifted to the right in the direction of the first loop structure 18A of the second winding 2W2 so that the end of the first loop structure 18A is still guided in the upper plane of the circuit carrier 11 rather than in the lower plane of the circuit carrier 11.
