Description

[0001] Magnetic field sensitive assembly, inductive component, method and use

[0002] The invention relates to a magnetic field sensitive assembly, an inductive component, a method and a use.

[0003] Inductive components, in particular chokes, are used for a variety of electronic and / or electrical applications, preferably for limiting currents in electrical lines, for temporarily storing energy in the form of its magnetic field, for impedance matching and / or for filtering an electronic and / or electrical signal.

[0004] When using an inductive component as a suppression choke, direct current and low-frequency currents should not be influenced or only slightly influenced by the choke, while high-frequency alternating currents should be effectively reduced by utilizing the impedance of the inductance.

[0005] Connecting lines in DC networks typically have a forward and a return line. The interference currents that occur in such lines can be divided into common-mode interference currents and differential-mode interference currents. Common-mode interference currents are interference currents on the connecting lines between electrical components or electrical elements that occur with the same current direction on both the forward and return lines. In contrast, differential-mode interference currents propagate in the opposite direction on connecting lines.

[0006] Until now, it has been necessary to use separate components, particularly chokes, for filtering or attenuating differential-mode and common-mode interference currents in such DC networks. While this has proven generally successful, some consider it disadvantageous because such an arrangement is relatively complex and requires a relatively large amount of space.

[0007] Particularly for mobile applications and / or other space- and cost-sensitive applications, there is a desire to design the required functions in the most space-saving, cost-effective, and robust way possible. Furthermore, a good filter effect for high-frequency interference currents, a temperature that is as constant as possible, and good adaptability to the intended application are desirable.

[0008] The invention is based on the object of providing an improvement or an alternative to the prior art.

[0009] According to a first aspect of the invention, this object is achieved by a magnetic field sensitive assembly, comprising: an annular magnetic field sensitive component and at least one web-shaped magnetic field sensitive component accommodated in a housing; wherein the annular magnetic field sensitive component has a longitudinal direction and a centrally arranged through-opening extending in the longitudinal direction, wherein the through-opening is designed in cross section as an oval with two axes of symmetry; wherein the annular magnetic field sensitive component has an inner cylindrical surface and an outer cylindrical surface; wherein the web-shaped magnetic field sensitive component is cuboid-shaped, has a base surface and a cover surface and is arranged within the through-opening, wherein the base surface and the cover surface are arranged to correspond to the inner cylindrical surface;wherein the housing has at least one first penetration which extends through the housing within the through-opening of the annular magnetic field-sensitive component; wherein the magnetic field-sensitive assembly has at least one clamping means which is designed to clamp the web-shaped magnetic field-sensitive component within the annular magnetic field-sensitive component.

[0010] The invention is based on the fundamental idea of ​​creating a magnetic field sensitive assembly that can effectively filter or attenuate both common mode interference currents and differential mode interference currents.

[0011] The ring-shaped, magnetic-field-sensitive component is particularly optimized for the attenuation or cancellation of common-mode interference currents. Cancellation preferably occurs through the superposition of the common-mode interference currents in the magnetic flux. Since the electrical lines are usually routed around the ring-shaped, magnetic-field-sensitive component in opposing regions or through a penetration, the common-mode interference currents each cause a magnetic flux in the ring-shaped component. The magnetic fluxes can overlap, thereby canceling them out. As a result, the common-mode interference currents are filtered by the magnetic-field-sensitive assembly.

[0012] In contrast, the ridge-shaped magnetic-field-sensitive component primarily serves to dampen differential-mode interference currents. For this purpose, the ridge-shaped magnetic-field-sensitive component preferably has a significantly lower permeability than the ring-shaped magnetic-field-sensitive component, but a significantly higher coercive field strength.

[0013] The module according to the invention can efficiently attenuate or filter out both common-mode and differential-mode interference currents. This eliminates the need to provide separate modules, preferably designed as chokes, for each type of interference current. This allows an electrical system to be optimized in terms of space, weight, and cost.

[0014] By clamping the web-shaped magnetic field sensitive component within the ring-shaped magnetic field sensitive component, the two components lie against one another, particularly flatly. This prevents an air gap between the components, which can have a negative effect on the properties of the magnetic field sensitive assembly. By clamping the web-shaped magnetic field sensitive component to the ring-shaped magnetic field sensitive component in this way, manufacturing tolerances can also be compensated, particularly in the ring-shaped component. In addition, the assembly of the magnetic field sensitive assembly is simplified, since the web-shaped component can be inserted into the through-opening of the ring-shaped component with some play before it is clamped.The fact that there is no longer a gap between the ridge-shaped magnetic-field-sensitive component and the ring-shaped magnetic-field-sensitive component results in defined magnetic properties of the assembly and thus a high reproducibility of the damping effect. At the same time, changes in length resulting from temperature fluctuations during operation are compensated.

[0015] The following term is explained in this regard:

[0016] First of all, it should be expressly pointed out that in the context of this patent application, indefinite articles and numerical expressions such as "one", "two", etc. are generally to be understood as "at least" expressions, i.e. as "at least one...", "at least two...", etc., unless it is expressly clear from the respective context or it is obvious or technically necessary for the person skilled in the art that only "exactly one...", "exactly two...", etc. can be meant.

[0017] In the context of this patent application, the expression "in particular" should always be understood as introducing an optional, preferred feature. The expression should not be understood as "and indeed" or "namely".

[0018] A “magnetic field sensitive component” is understood to be a component, in particular a ferromagnetic component, which reacts to a magnetic field by changing at least one state variable of the component. A magnetic field sensitive component can be used, among other things, together with electrically conductive conductors to produce an inductive component which can be used for electrical and / or electronic applications. An “oval” is a flat, round, convex figure. An oval includes circles and ellipses as special cases, although unlike these, an arbitrary oval does not need to have an axis of symmetry. In particular, an oval is a closed, twice continuously differentiable convex curve in the plane.

[0019] If the curve of an oval is arranged in a mirror image on both sides of an imaginary line, then the oval has one axis of symmetry. If the curve of an oval is arranged in a mirror image on both sides of two non-coincident imaginary lines, then the oval has two axes of symmetry. In particular, a circle and an ellipse are each ovals with two axes of symmetry.

[0020] The annular magnetic-field-sensitive component can be circular. In this case, the through-opening has a circular cross-section. Alternatively, the annular magnetic-field-sensitive component can also comprise two opposing rectilinear sections that run parallel to one another and are connected by semicircular arcs. Preferably, the annular magnetic-field-sensitive component has an at least substantially constant, in particular rectangular, cross-section over its entire circumference.

[0021] The annular magnetic field sensitive component can extend in the longitudinal direction over a length of at least 15 mm, in particular of at least 20 mm, preferably of at least 25 mm, particularly preferably of at least 35 mm, and / or at most 100 mm, in particular of at most 75 mm, preferably of at most 60 mm, particularly preferably of at most 40 mm. The opening width of the through opening, in particular in a section of the through opening in which the web-shaped magnetic field sensitive component is located, can be at least 8 mm, in particular at least 12 mm, preferably at least 15 mm, and / or at most 50 mm, in particular of at most 40 mm, preferably of at most 30 mm. The opening width is particularly preferably 20 mm.

[0022] Such dimensions have proven advantageous for the attenuation properties of the magnetic-field-sensitive assembly, particularly for filtering common-mode interference currents. The dimensions can be adapted to the specific application.

[0023] A "through-opening" is understood to mean a free cross-section formed in the interior region of the magnetic-field-sensitive component. Preferably, the through-opening extends in the direction of an axial extent of the magnetic-field-sensitive component.

[0024] A "housing" is understood to mean a component which electrically and / or electronically insulates at least the annular magnetic field-sensitive component and / or the web-shaped magnetic field-sensitive component from its surroundings. Furthermore, the housing can be designed to accommodate at least the annular magnetic field-sensitive component and / or the web-shaped magnetic field-sensitive component and to enable a relative arrangement of the accommodated components to one another. In other words, the housing can influence the relative position of the annular magnetic field-sensitive component and / or the web-shaped magnetic field-sensitive component.

[0025] The housing can consist of a plastic, in particular of a thermoplastic and / or a thermosetting plastic, or can comprise such a material.

[0026] Advantageously, the housing can be manufactured or be manufactured from a thermoplastic and / or a thermosetting plastic in an injection molding process and / or a thermoforming process and / or a PUR-RIM process and / or another plastic manufacturing process.

[0027] The housing can at least partially enclose, in particular completely enclose, the annular magnetic field sensitive component and / or the web-shaped magnetic field sensitive component.

[0028] The housing preferably has a temperature resistance of greater than or equal to 120 ° C, preferably a temperature resistance of greater than or equal to 150 ° C and particularly preferably a temperature resistance of greater than or equal to 180 ° C.

[0029] A "penetration" of the housing is understood to mean a free cross-section extending through the housing. The penetration can have an oval cross-section, preferably an elliptical or circular cross-section or any other cross-section, in particular a D-shaped or semicircular cross-section. The penetration can penetrate the housing completely. In other words, a designated electrical conductor can penetrate the housing through the penetration.

[0030] The penetrations can run along parallel axes in the housing. Preferably, the penetrations can penetrate the housing in the direction of its longitudinal extension.

[0031] Advantageously, the axis of the through-opening of the first magnetic-field-sensitive component can run, at least in sections, coaxially with the axis of the first penetration of the housing. This further simplifies the routing of a designated electrical conductor through the through-opening of the first magnetic-field-sensitive component and through the first penetration of the housing. According to a further embodiment of the invention, the housing can have at least a first penetration and a second penetration, which extend through the housing on both sides of the web-shaped magnetic-field-sensitive component and within the through-opening of the annular magnetic-field-sensitive component.

[0032] This can provide for an electrical conductor to be guided through each penetration and, in particular, to be guided around the annular magnetic-field-sensitive component adjacent to the penetration. This allows interference currents to induce a magnetic flux into the annular magnetic-field-sensitive component.

[0033] Advantageously, the web-shaped magnetic field sensitive component is formed in one piece.

[0034] With a one-piece design of the web-shaped magnetic-field-sensitive component, disturbances in the magnetic flux caused by several adjacent components can be prevented. In principle, however, it is also conceivable for the web-shaped magnetic-field-sensitive component to be constructed in several parts, in particular comprising several components extending parallel to one another, each of which preferably has a cuboidal basic shape.

[0035] The web-shaped magnetic field-sensitive component can lie flat against the annular magnetic field-sensitive component at its base surface and its cover surface, which preferably form two opposite end faces. Accordingly, the base surface and the cover surface can be designed as flat surfaces, in particular when the web-shaped magnetic field-sensitive component lies flat against corresponding rectilinear sections of the annular magnetic field-sensitive component. Alternatively, the base surface and the cover surface can also be designed as concave surfaces, which can in particular be designed as a segment of a circular cylinder jacket. Such a configuration is recommended when the annular magnetic field-sensitive component is annular.

[0036] The web-shaped component preferably has a rectangular cross-section. The web-shaped magnetic field-sensitive component is preferably designed such that it has no abrupt cross-sectional transitions, in particular transverse to the direction of longitudinal extent. In particular, the web-shaped magnetic field-sensitive component only has continuous cross-sectional transitions, which are preferably rounded. The web-shaped magnetic field-sensitive component particularly preferably has a constant cross-section transverse to the direction of longitudinal extent. This enables a favorable magnetic flux through the web-shaped magnetic field-sensitive component. The web-shaped magnetic field-sensitive component can be flush with the annular magnetic field-sensitive component in the direction of longitudinal extent.

[0037] The web-shaped magnetic field-sensitive component can extend transversely to the longitudinal direction over a width of at least 7 mm, in particular of at least 9 mm, preferably of at least 12 mm, and / or of at most 25 mm, in particular of at most 18 mm, preferably of at most 16 mm, particularly preferably over a width of 14 mm or 15 mm.

[0038] Such dimensions have proven advantageous for the damping properties of the magnetic-field-sensitive assembly, particularly for damping differential-mode interference currents. The dimensions can be adapted to each specific application. According to a preferred embodiment, the housing is constructed in at least two parts, in particular in exactly two parts. The housing preferably has a housing shell and a housing cover.

[0039] An advantage of such a construction is its simple assembly, since the two parts of the housing can be easily connected to one another after the ring-shaped magnetic field-sensitive component and the web-shaped magnetic field-sensitive component have been inserted into one of the two housing parts, preferably into the housing shell.

[0040] The housing shell can comprise a base plate that covers a longitudinal end face of the annular magnetic-field-sensitive component and / or the web-shaped magnetic-field-sensitive component. Circumferential side walls can protrude from this base plate and cover at least the annular magnetic-field-sensitive component, preferably its outer cylindrical surface.

[0041] Accordingly, a housing cover can comprise a cover plate which covers the longitudinal end face of the annular magnetic field sensitive component and / or the web-shaped magnetic field sensitive component opposite the base plate. Engagement means can be formed on the housing shell and / or the housing cover, by means of which the housing shell and the housing cover can be connected to one another in a form-fitting manner. Specifically, the engagement means can have positioning projections formed on the housing cover, in particular circumferential positioning projections, which bear against the free ends of the side walls of the housing shell in order to position the housing cover relative to the housing shell. The positioning projections preferably bear from the outside against the free ends of the side walls of the housing shell.As a result, particularly when the clamping means is formed on the side wall of the housing shell, the positioning projection can absorb the counterforce to the clamping force.

[0042] In addition, inner side walls can be formed on the housing shell or on the housing cover, which define / define the at least one penetration or surround / surround it. Corresponding positioning projections, which are in particular designed to be circumferential, can be provided on the other of the two housing elements in order to support the inner side walls. By means of such an engagement, which is preferably realized on both the outer side walls and the inner side walls, a high level of mechanical stability of the housing can be achieved. Sections of the side walls can bear against the web-shaped magnetic field-sensitive component and / or the ring-shaped magnetic field-sensitive component in order to position them clearly relative to one another.

[0043] The housing cover and the housing shell can also be held together by means of securing means. It is conceivable that the housing cover and the housing shell are glued together in the area of ​​the positioning projections and the side walls. It is also possible to provide appropriate screw connections between the housing cover and the housing shell. Other designs of securing means are also conceivable.

[0044] In a further embodiment of the present invention, the clamping means can be arranged within the housing.

[0045] Accordingly, the clamping means can preferably be supported between a side wall of the housing and the outer cylinder surface. The clamping means preferably acts on the outer cylinder surface.

[0046] Thus, it can be provided that the ring-shaped magnetic field-sensitive component is compressed from the outside in order to eliminate any play that exists during assembly between the ring-shaped magnetic field-sensitive component and the web-shaped magnetic field-sensitive component.

[0047] The clamping means is preferably designed such that opposite sides of the annular magnetic field sensitive component are pressed towards each other and elastically deformed in order to clamp a web-shaped magnetic field sensitive component arranged therebetween. In other words, the opening width of the through-opening can be slightly reduced by the clamping means in order to clamp a web-shaped magnetic field sensitive component arranged therebetween. This can ensure that there is no air gap between the annular component and the web-shaped component, which would minimize the effectiveness of the web-shaped magnetic field sensitive component. The clamping means can prestress the annular magnetic field sensitive component, in other words exert a prestressing force on the annular magnetic field sensitive component.The preload force is selected in such a way that any play which exists during assembly between the web-shaped component and the ring-shaped component is eliminated.

[0048] According to a further embodiment, the clamping means can have a fixed geometry.

[0049] In other words, a dimensionally stable formation on a side wall of the housing or a corresponding dimensionally stable clamping element can be provided in order to clamp the web-shaped magnetic field-sensitive component in the ring-shaped magnetic field-sensitive component.

[0050] The clamping means can be designed as a component of the housing, in particular as a component of the housing shell.

[0051] For example, the clamping means may comprise a projection formed in a side wall of the housing, which presses against the outer cylinder surface from the outside. Preferably, a corresponding clamping projection is formed inwardly on each of two opposite side walls.

[0052] It is also possible for the clamping means to be designed as a separate clamping element independent of the housing. Such a design has the advantage that, similar to a shim, the clamping element can be selected depending on the dimensions of the specific annular, magnetic-field-sensitive component in question, in order to generate a precisely defined clamping force. To hold the clamping element to the housing, appropriate fastening means can be provided, which preferably act in a force-fitting and / or positive-fitting manner.

[0053] The clamping means may have a curvature which is formed transversely to the longitudinal direction.

[0054] Such a curvature or a clamping projection reduces the notch stresses, which has a beneficial effect on the magnetic properties.

[0055] Alternatively, the clamping means can have a curvature and / or a wedge bevel which is formed in the direction of longitudinal extension. This can reduce the stresses that occur when the housing shell and the housing cover are connected to one another from both sides during assembly of the housing. A wedge bevel can be provided on the side wall of the housing, wherein the wedge bevel only extends over a partial region of the longitudinal extension of the annular magnetic field-sensitive component. In other words, in this case the clamping means only acts on a longitudinal section of the annular magnetic field-sensitive component. This reduces the stresses that occur during assembly, which makes joining the housing easier.

[0056] In a further embodiment, the clamping means can be an adjustable clamping means.

[0057] One advantage of such an adjustable clamping device is that the clamping force can be precisely adjusted. Due to manufacturing tolerances, the distance between the opposing sides of the annular magnetic-field-sensitive component can vary. Such an adjustable clamping device can enable individual adjustment of the clamping force. For example, a clamping screw can be provided which is movably mounted on the housing so that it can exert a compressive force on the annular magnetic-field-sensitive component from the outside.

[0058] According to a preferred embodiment, the web-shaped magnetic field-sensitive component can have a relative permeability of greater than or equal to 10, preferably a relative permeability of greater than or equal to 50, further preferably a relative permeability of greater than or equal to 100 and particularly preferably a relative permeability of greater than or equal to 300. The web-shaped magnetic field-sensitive component can expediently have a relative permeability of greater than or equal to 500, preferably a relative permeability of greater than or equal to 1,000, further preferably a relative permeability of greater than or equal to 1,500 and particularly preferably a relative permeability of greater than or equal to 2,000.

[0059] Permeability is a measure of the magnetization of a material in an external magnetic field. The higher the permeability of a magnetic-field-sensitive component, the greater the ratio of the magnetic flux density in the magnetic-field-sensitive component to the magnetic field strength acting on the magnetic-field-sensitive component. Thus, a magnetic-field-sensitive component with high permeability results in a comparatively high magnetic flux density in the magnetic-field-sensitive component, even at a low magnetic field strength.

[0060] With the above-described values ​​of the relative permeability, a designated magnetic flux of the web-shaped magnetic field-sensitive component can be influenced in an advantageous range.

[0061] This makes it possible to optimize the magnetic-field-sensitive assembly used for an inductive component not only for attenuation of common-mode interference currents (due to the material properties of the ring-shaped component) but also for attenuation of differential-mode interference currents (due to the material properties of the ridge-shaped component). Usually, the attenuation of common-mode interference currents and the attenuation of differential-mode interference currents are achieved by separate inductive components, so that overall functional integration can be achieved with the inductive component proposed here.

[0062] Optionally, the web-shaped magnetic field-sensitive component can have a relative permeability of less than or equal to 5,000, preferably a relative permeability of less than or equal to 3,500, further preferably a relative permeability of less than or equal to 2,000 and particularly preferably a relative permeability of less than or equal to 1,500.

[0063] Preferably, the web-shaped magnetic field-sensitive component can have a relative permeability of less than or equal to 1,000, preferably a relative permeability of less than or equal to 500, further preferably a relative permeability of less than or equal to 300 and particularly preferably a relative permeability of less than or equal to 100.

[0064] The web-shaped magnetic field-sensitive component can have a coercive field strength of greater than or equal to 12 A / m, preferably greater than or equal to 120 A / m and particularly preferably greater than or equal to 1,200 A / m.

[0065] Such coercive field strengths support the attenuation of differential-mode interference currents. The "coercive field strength" refers to the magnetic field strength required to completely demagnetize a magnetic-field-sensitive component that has previously been charged to the saturation flux density.

[0066] According to a preferred embodiment of the invention, the web-shaped magnetic field-sensitive component is made of a soft magnetic material, in particular sintered therefrom.

[0067] A "soft magnetic material" is a material that can be easily magnetized in a magnetic field. A soft magnetic material preferably has a coercive field strength of less than or equal to 1,000 A / m.

[0068] Preferably, a soft magnetic material, in particular an amorphous soft magnetic material, preferably a metallic glass, comprises an alloy comprising iron, nickel and / or cobalt.

[0069] A "metallic glass" is understood to be a metal-based alloy of a substance that has an amorphous rather than a crystalline structure at the atomic level, yet still possesses metallic conductivity as a property. Preferably, a metallic glass can contain non-metallic alloy components in addition to metallic alloy components.

[0070] The amorphous atomic arrangement, which is very unusual for metals, advantageously enables special physical properties. In particular, the use of metallic glasses can advantageously reduce the coercive field strength of magnetic-field-sensitive components and / or advantageously increase their permeability.

[0071] Preferably, a soft magnetic material can have the following atomic composition:

[0072] [Fei- a Ni a ] ioo-xyza-ß-Y Cu x Si y B z NbaM' ßM" Y with a < 0.3, 0.6 < x < 1.5, 10 < y < 17, 5 < z < 14, 2 < a < 6, ß < 7, y < 8, where M' is at least one of the elements V, Gr, Co, Al and Zn, where M" is at least one of the elements C, Ge, P, Ga, Sb, In and Be.

[0073] Furthermore, a soft magnetic material can preferably comprise 73.5 wt.% iron and / or 1 wt.% copper and / or 3 wt.% niobium and / or 13.5 wt.% silicon and / or 9 wt.% boron. A soft magnetic material can expediently comprise 74.5 wt.% iron and copper, wherein the copper content is less than or equal to 1 wt.%. In a further embodiment, the web-shaped magnetic field-sensitive component can be polished at least partially on the base surface and / or on the cover surface and / or the ring-shaped magnetic field-sensitive component on the inner cylinder surface. In particular, the corresponding surfaces can have a roughness R a less than or equal to 1 , 6 pm, preferably a roughness R a of less than or equal to 0 , 8 pm and particularly preferably a roughness R a of less than or equal to 0.4 pm.

[0074] A "roughness" refers to the unevenness of the surface height. For the quantitative characterization of roughness, there are different calculation methods, each of which takes into account different characteristics of the surface. The "roughness R a " or mean roughness indicates the average distance of a measuring point on the surface to the center line .

[0075] Surface irregularities, such as notches, lead to disruption of the magnetic flux. Due to the low roughness of the base and / or top surfaces of the ridge-shaped magnetic-field-sensitive component and / or of the inner cylindrical surface of the ring-shaped magnetic-field-sensitive component, the adverse influence caused by the roughness on the magnetic flux through these surfaces can be reduced. Accordingly, the reproducibility of the properties of the magnetic-field-sensitive assembly can be improved.

[0076] The ring-shaped magnetic field-sensitive component can expediently have a relative permeability of greater than or equal to 1,000, preferably a relative permeability of greater than or equal to 5,000, furthermore preferably a relative permeability of greater than or equal to 10,000 and particularly preferably a relative permeability of greater than or equal to 20,000. Furthermore expediently, the ring-shaped magnetic field-sensitive component can have a relative permeability of greater than or equal to 30,000, preferably a relative permeability of greater than or equal to 45,000, furthermore preferably a relative permeability of greater than or equal to 60,000 and particularly preferably a relative permeability of greater than or equal to 75,000.

[0077] The above-suggested values ​​of relative permeability for the ring-shaped magnetic field sensitive component allow for improved compensation of high-frequency common mode interference currents induced on the load side or the mains side.

[0078] According to an optional embodiment, the ring-shaped magnetic field-sensitive component can have a relative permeability of less than or equal to 150,000, preferably a relative permeability of less than or equal to 100,000, further preferably a relative permeability of less than or equal to 90,000 and particularly preferably a relative permeability of less than or equal to 75,000. Furthermore expediently, the ring-shaped magnetic field-sensitive component can have a relative permeability of less than or equal to 60,000, preferably a relative permeability of less than or equal to 45,000, further preferably a relative permeability of less than or equal to 30,000 and particularly preferably a relative permeability of less than or equal to 20,000. The permeability is preferably measured in a magnetic field oscillating at 50 Hz.

[0079] Advantageously, the annular magnetic field-sensitive component can have a magnetic saturation flux density of greater than or equal to 1 T, preferably greater than or equal to 1.2 T, and particularly preferably greater than or equal to 1.4 T. Thus, when the magnetic field-sensitive assembly is used as an inductive component, even with comparatively large interference currents, it can be ensured that the annular magnetic field-sensitive component is not transferred into a saturation state.

[0080] The "saturation flux density" is a measure of the maximum extent to which a material can be magnetized by an applied magnetic field. The flux density initially increases continuously with increasing field strength. From a certain value, this effect diminishes greatly, so that a further increase in field strength leads to only a very small increase in the flux density in the material. The flux density at which this flattening occurs is called the saturation flux density.

[0081] Advantageously, the annular magnetic-field-sensitive component can have a coercive field strength of less than or equal to 10 A / m, preferably a coercive field strength of less than or equal to 5 A / m, and particularly preferably a coercive field strength of less than or equal to 3 A / m. This results in reduced heat loss due to a changing magnetic field in the annular magnetic-field-sensitive component. In this way, the annular magnetic-field-sensitive component can be made even smaller while maintaining constant common-mode interference currents, thus further increasing the power density of the magnetic-field-sensitive assembly.

[0082] Preferably, the ring-shaped magnetic field-sensitive component comprises a soft magnetic material, in particular a metallic glass, preferably having a nanocrystalline structure.

[0083] The ring-shaped magnetic field-sensitive component can be constructed in layers from a soft magnetic material; in particular, the magnetic field-sensitive component can be wound from a soft magnetic material. This allows the eddy current losses of the magnetic field-sensitive component to be influenced. Preferably, the eddy current losses can be specifically adjusted via those of the soft magnetic material, whereby the eddy current losses and thus the impedance of the magnetic field-sensitive component can be adjusted. In other words, the eddy current losses and the impedance can be adjusted via the strip thickness. The impedance of the magnetic field-sensitive component can be used to influence and / or adjust the transmission behavior of the magnetic field-sensitive component, in particular the attenuation of the magnetic field-sensitive component, with respect to high-frequency currents.This makes it possible to ensure that high-frequency currents, in particular high-frequency interference currents, are partially or completely dissipated by the magnetic field-sensitive component.

[0084] The annular magnetic-field-sensitive component can, in particular, be wound circumferentially from a strip. The strip thickness can be at least 5 pm, in particular at least 10 pm, preferably at least 15 pm, and / or at most 200 pm, in particular at most 100 pm, preferably at most 25 pm. The strip thickness is particularly preferably 20 pm.

[0085] The total number of windings can be at least 100, in particular at least 250, preferably at least 400, and / or at most 1,500, in particular at most 1,000, preferably at most 600. Particularly preferably, the annular magnetic field-sensitive component comprises 500 windings.

[0086] Such a wound, annular, magnetic-field-sensitive component leads to relatively high manufacturing tolerances, particularly with regard to the opening width of the through-opening, which can be compensated for accordingly by the clamping means. Advantageously, a relative permeability of the annular, magnetic-field-sensitive component can be greater than a relative permeability of the web-shaped, magnetic-field-sensitive component by a factor of greater than or equal to 1.1, in particular by a factor of greater than or equal to 10, preferably by a factor of greater than or equal to 100, and particularly preferably by a factor of greater than or equal to 1,000.

[0087] A magnetic field sensitive assembly designed in this way can react particularly quickly to high frequency alternating currents and thus compensate even better for interference currents induced on the load side and / or the mains side.

[0088] The permeability of the magnetic field sensitive assembly, in particular with regard to the web-shaped magnetic field sensitive component, can be specified or adjusted in a more user-specific and thus even more individually if the web-shaped magnetic field sensitive component and the ring-shaped magnetic field sensitive component are arranged at a distance from one another, wherein a gap, in particular an air gap, is arranged on a head side of the web-shaped magnetic field sensitive component opposite the ring-shaped magnetic field sensitive component.

[0089] A head side is understood to mean each side of the web-shaped magnetic field-sensitive component which, in the designated arrangement of the web-shaped magnetic field-sensitive component, is arranged within the ring-shaped magnetic field-sensitive component and corresponding to an inner lateral surface of the ring-shaped magnetic field-sensitive component.

[0090] In the present case, a gap is to be understood as a distance between the web-shaped magnetic field-sensitive component and the ring-shaped magnetic field-sensitive component. This gap can be filled with ambient air or by a different medium filling the gap, in particular by a solid body which, in the function of a spacer element on the inside of the ring-shaped magnetic field-sensitive component, distances it from the web-shaped magnetic field-sensitive component. In this way, the permeability of the gap can be adapted; in particular, the gap can have the permeability of air and / or the permeability of the spacer element. In this case, low-permeability materials are essentially intended, in particular air, compared to the web-shaped magnetic field-sensitive component and / or the ring-shaped magnetic field-sensitive component.

[0091] Preferably, a gap may comprise a magnetic powder, in particular a magnetic powder dispersed in a plastic or other suitable material.

[0092] This allows the effective permeability of the magnetic short circuit of the ring-shaped magnetic field-sensitive component induced by the web-shaped magnetic field-sensitive component to be varied and / or adapted to the individual designated operating conditions for the magnetic field-sensitive assembly proposed here. This allows, among other things, the adjustment of filtering of common-mode interference currents and / or differential-mode interference currents.

[0093] It is understood that the magnetic-field-sensitive assembly proposed here can also have a gap between the web-shaped magnetic-field-sensitive component and the ring-shaped magnetic-field-sensitive component on both sides of the web-shaped magnetic-field-sensitive component and / or on all head sides of the web-shaped magnetic-field-sensitive component within the ring-shaped magnetic-field-sensitive component, in particular on two or three or more head sides. It is also contemplated that the corresponding gaps can be filled with different media and / or materials.

[0094] Advantageously, a gap can be filled with a solid body which fixes the web-shaped magnetic field sensitive component in the ring-shaped magnetic field sensitive component, in particular a cured adhesive.

[0095] According to a second aspect of the invention, the object is achieved by an inductive component having a magnetic field sensitive assembly according to the first aspect of the invention, wherein the housing has at least a first penetration and a second penetration which extend through the housing on both sides of the web-shaped magnetic field sensitive component and within the through opening of the ring-shaped magnetic field sensitive component, a first conductor and a second conductor; wherein the first conductor is guided at least once through the first penetration; and wherein the second conductor is guided at least once through the second penetration.

[0104] It is understood that the advantages of a magnetic field sensitive assembly according to the first aspect of the invention, as described above, extend directly to the use of a magnetic field sensitive assembly according to the first aspect of the invention as an inductive component.

[0118] In the description that follows, the same reference symbols designate the same components or the same features, so that a description given with reference to one figure regarding a component also applies to the other figures, so that a repetitive description is avoided. Furthermore, individual features that were described in connection with one embodiment can also be used separately in other embodiments. Figure 1 shows an inductive component 20 according to the present invention. This comprises a magnetic field-sensitive assembly 10 that has a housing 100 with a first penetration 101 and a second penetration 102. Both penetrations 101, 102 are D-shaped. A first conductor 201 passes through the first penetration 101 and a second conductor 202 passes through the second penetration 102.

[0119] The basic structure of a magnetic field sensitive assembly 10 according to the present invention is shown in Figures 2 and 3.

[0120] The magnetic field-sensitive assembly 10 has an annular magnetic field-sensitive component 110. This has a longitudinal direction 111 and a centrally arranged through-opening 112 extending in the longitudinal direction 111, which in this case is formed in cross-section as an oval with two axes of symmetry. Specifically, the annular magnetic field-sensitive component 110 comprises two opposing rectilinear sections 115 that run parallel to one another and are connected to one another by semicircular arcs 116. Over its entire circumference, the annular magnetic field-sensitive component 110 has a uniform square cross-section.

[0121] Accordingly, the ring-shaped magnetic field-sensitive component 110 has an inner cylindrical surface 113 and an outer cylindrical surface 114. The inner cylindrical surface 113 is polished and has a roughness R a from about 0 , 4 pm to .

[0122] In this case, the annular magnetic-field-sensitive component 110 consists of a soft magnetic material formed as metallic glass, which is wound circumferentially from a strip. The strip thickness is approximately 20 μm, and the annular magnetic-field-sensitive component comprises a total of 500 windings. The soft magnetic material has a relative permeability of more than 30,000 and a coercive field strength of less than 3 A / m.

[0123] The magnetic field sensitive assembly 10 further comprises a cuboidal, web-shaped magnetic field sensitive component 120. This is formed in one piece and has a flat base surface 121 and a flat cover surface 122, which in the present case form two opposite end faces. The base surface 121 and the cover surface 122 are flat and polished such that the roughness R a is about 0.4 pm .

[0124] The web-shaped component 120 is arranged within the through-opening 112 of the annular magnetic-field-sensitive component 110, with the base surface 121 and the cover surface 122 each resting flat against the inner cylindrical surface 113 of the annular magnetic-field-sensitive component 110. In the longitudinal direction, the web-shaped magnetic-field-sensitive component 120 is flush on both sides with the longitudinal end faces of the annular magnetic-field-sensitive component 110.

[0125] The web-shaped magnetic-field-sensitive component 120 is sintered from a soft magnetic material. This soft magnetic material has a coercive field strength of approximately 1,200 A / m and a relative permeability of less than 100.

[0126] The ring-shaped magnetic-field-sensitive component 110 and the web-shaped magnetic-field-sensitive component 120 are completely enclosed by a housing 100 made of a plastic material. The plastic material is selected such that it has a temperature resistance of more than 180°C. Specifically, the housing 100 comprises a housing shell 103 and a housing cover 104, which are connected to one another.

[0127] The housing shell 103 has a base plate 106, which covers a longitudinal end face of the annular magnetic-field-sensitive component 110 and the web-shaped magnetic-field-sensitive component 120. Circumferential side walls 107 protrude from this base plate 106 and cover the annular magnetic-field-sensitive component 110, specifically its outer cylindrical surface 114. Inner side walls 107, each defining a penetration 101, 102, protrude from the base plate 106 and cover the inner cylindrical surface 113 and the side surface of the web-shaped magnetic-field-sensitive component 110 facing the respective penetration 101, 102.

[0128] The housing cover 104 comprises a cover plate 108 which covers the longitudinal end face of the annular magnetic field sensitive component 110 and the web-shaped magnetic field sensitive component 120 opposite the base plate 106. Engagement means are formed on the housing shell 103 and the housing cover 104, via which engagement means the housing shell 103 and the housing cover 104 engage with one another in a form-fitting manner. The engagement means comprise circumferential positioning projections 109 formed on the housing cover 104, which bear against the free ends of the side walls 107 of the housing shell 103 in order to position the housing cover relative to the housing shell. The positioning projections 109 bear from the outside against the free ends of the side walls 107 of the housing shell 103.Specifically, for this purpose, a positioning recess 109a corresponding to the positioning projections 109 is provided at the free ends of the side walls 107, so that the side walls 107 are tapered at their free ends. Figure 2 shows that a small gap is formed all the way around between the side walls 107 and the annular magnetic field sensitive component 110 or the web-shaped magnetic field sensitive component 120. It is also conceivable that such a gap is missing, in particular between the inner side walls 107 and the web-shaped magnetic field sensitive component 120, i.e. the side walls 107 abut the web-shaped magnetic field sensitive component 120 in order to position the web-shaped magnetic field sensitive component 120 uniquely relative to the ring-shaped magnetic field sensitive component 110.

[0129] In addition, the magnetic field sensitive assembly 10 has at least one clamping means 105, which is shown only schematically in Figures 2 and 3 with regard to its function by the arrows. The clamping means 105 is designed to clamp the web-shaped magnetic field sensitive component 120 within the annular magnetic field sensitive component 110. In this case, the clamping means acts on the outer cylindrical surface 114 of the annular magnetic field sensitive component 110. In other words, it applies a clamping force from the outside to the outer cylindrical surface 114, so that the annular magnetic field sensitive component 110, in particular its straight sections 115, are pressed together from the outside in order to clamp the web-shaped magnetic field sensitive component 120 arranged within the through opening 112.In other words, the ring-shaped magnetic field sensitive component 110 is elastically deformed.

[0130] The clamping means 105 and the clamping force generated thereby ensure that the base surface 121 and the cover surface 122 of the web-shaped magnetic-field-sensitive component 120 lie flat against the inner cylindrical surface 113 of the annular magnetic-field-sensitive component 110. Various exemplary embodiments of the clamping means 105 are shown in detail in Figures 4 to 8.

[0131] A first embodiment is shown in Figures 4 and 5. A corresponding clamping projection 105a is formed in the side wall 107 of the housing shell 103, which clamping projection presses against the outside of the annular magnetic field-sensitive component 110 and thus elastically deforms it inward in order to clamp the web-shaped magnetic field-sensitive component 120 between opposing sections of the inner cylindrical surface 113.

[0132] The clamping projection 105a extends over the entire length of the annular magnetic field-sensitive component 110. During assembly, it is necessary to manually apply a preload force to the side wall 107 of the housing 100 before the housing cover 104 is placed on the housing shell 103 and the positioning projection 109 engages the side wall 107 from the outside.

[0133] Figure 6 shows an alternative embodiment of the clamping means 105. In this case, a clamping projection 105a is also formed on the side wall 107 of the housing shell 103. However, this does not extend continuously over the entire length of the annular magnetic field-sensitive component 110, but is wedge-shaped, so that it only acts on the annular magnetic field-sensitive component 110 at one longitudinal end region. Such a configuration facilitates assembly, since the annular magnetic field-sensitive component 110 can initially be inserted into the housing shell 103 without any force resistance, and only at the end of this insertion is a clamping force exerted on the annular magnetic field-sensitive component 110 by the wedge-shaped clamping projection 105a. Figure 7 shows a further possible embodiment of a clamping means 105.In this case, unlike the two previous embodiments, the clamping means 105 is not formed as a component of the housing 100, but as a separate clamping element 105b. Such a configuration has the advantage that, similar to a shim, the clamping element 105b can be selected depending on the dimensions of the respective specific annular magnetic field-sensitive component 110 in order to generate a precisely defined clamping force. In order to hold the clamping element 105b to the housing 100, appropriate fastening means can be provided, which preferably act in a force-fitting and / or form-fitting manner.

[0134] Figure 8 shows a further embodiment of a clamping means 105. The clamping means 105 is adjustable so that a defined force can be applied from the outside to the annular magnetic field sensitive component 110. Specifically, a clamping screw 105c is provided here, which is adjustably held on the housing 100, in this case on the side wall 107. For this purpose, corresponding metallic threaded inserts (not shown in Figure 8) can be provided on the housing 100. Due to the contact of the front end face of the clamping screw 105c with the outer cylinder surface 114 of the annular magnetic field sensitive component 110, a defined clamping force can be applied in order to clamp the web-shaped magnetic field sensitive component 120.

[0135] The embodiments of clamping means shown in Figures 4 to 8 can comprise a single clamping means 105 or a clamping means 105 on each of the opposite sides. The clamping means 105 explained above can also be combined with one another as desired. Further clamping means 105 not presented in detail are also conceivable. Clamping the web-shaped magnetic field sensitive component 120 within the ring-shaped magnetic field sensitive component 110 prevents an air gap between these components. This has a positive effect on the properties of the magnetic field sensitive assembly 10.

[0136] Because the web-shaped magnetic field sensitive component 120 has a significantly lower permeability but a significantly higher coercive field strength than the ring-shaped magnetic field sensitive component 110, the magnetic field sensitive assembly 10 is suitable for efficiently damping or filtering out both common mode interference currents and differential mode interference currents in the two conductors 201, 202.
