Definitions
- the invention relates to a common mode choke.
- the common mode choke has an in particular magnetically permeable toroidal core, in particular in the form of a circular ring.
- the common mode choke also has at least one coil and at least one further coil. The coil and the further coil are each arranged in the area of the toroidal core in such a way that a magnetic flux penetrating the coils can detect the toroidal core.
- EMC electro-magnetic compatibility
- common-mode chokes have at least two or only two coils, which can interact magnetically with one another via a toroidal core.
- the coil current in the two coils is preferably conducted in mutually different directions, so that EMC disturbances in the toroidal core magnetically cancel each other out.
- the toroidal core encloses an in particular cylindrical through-hole.
- the coils each comprise at least one or only one electrical inner conductor, in particular a busbar.
- the inner conductor is arranged in the opening, the coil winding having an outer conductor electrically connected to the inner conductor.
- the outer conductor forms a cylinder jacket section, in particular a cylinder jacket segment.
- the outer conductor is designed to enclose a circumferential section of the toroidal core.
- the common-mode choke can thus advantageously be provided in a particularly compact and cost-effective manner with a high level of inductance.
- the common-mode choke can thus be designed with low resistance in high-current applications, in particular with a current flow of several hundred amperes. This is because it was recognized that the impedance of a common mode choke can be effectively increased if the cross-sectional area of the opening can be fully energized by the inner conductors.
- the circumference of the toroidal core preferably extends along an annular circumference around the opening.
- the toroidal core is preferably designed in the shape of a circular ring, more preferably in the shape of a hollow cylinder.
- the inner conductors arranged in the opening jointly form a cylindrical shape and jointly fill the opening.
- the inner conductors preferably each have a cross-section in the shape of a segment of a circle.
- the common-mode choke can thus have an inner conductor which is semicylindrical and semicircular in cross section.
- the common mode choke in which each coil has two turns or partial turns, can have an inner conductor for each turn or partial turn, which is formed in the shape of a cylinder quarter segment or in cross section in the shape of a quarter segment. In this way, the breakthrough can advantageously be designed with a particularly small breakthrough cross section to form a large inductance of the common mode choke.
- the common mode choke can thus be provided in a particularly space-saving manner.
- the inner conductors are preferably each designed as a straight rod, in particular. In this way, the inner conductors can advantageously be provided with little effort by an extruded profile or a rolled profile and by being separated from a rod.
- the coils each have only one coil turn or partial coil turn and the outer conductors, or additionally the inner conductors, are designed to be semicircular in cross section for this purpose.
- the inner conductors of the coil and the further coil can advantageously make the breakthrough together completely or almost completely - preferably with the exception of an isolation gap.
- the outer conductors can advantageously completely or almost completely enclose the toroidal core, preferably with the exception of an insulation gap.
- the insulation gap can be filled with air or an insulator, preferably plastic or ceramic.
- the insulator is preferably formed by the holding body.
- the coils each have two coil turns or partial coil turns.
- the outer conductors and / or the inner conductors are each embodied in the form of a quarter segment in cross section.
- a common-mode choke with two coil windings or partial windings can thus advantageously have a high inductance insofar as the inductance of a common-mode choke increases quadratically with the number of turns.
- the common mode choke has an electrically insulating holding body, in particular a plastic body or ceramic body.
- the plastic body extends at least between mutually adjacent outer conductors or additionally between two mutually adjacent inner conductors.
- the holding body preferably extends between two coil turns adjacent to one another. As a result, the individual coil turns are advantageously electrically isolated from one another.
- the holding body in particular a plastic body or ceramic body, preferably encloses an annular cavity for receiving the toroidal core, which is designed to receive the toroidal core.
- the common-mode choke can thus advantageously be provided in a cost-effective and space-saving manner.
- the plastic body can, for example, be provided together with the outer conductors and the inner conductors in the injection molding process by overmolding the outer and inner conductors.
- the inner conductor and the outer conductor and a connecting section connecting the inner conductor and the outer conductor thus jointly form a coil turn or partial coil turn.
- a coil turn preferably extends along a complete turn around a coil core, in particular the toroidal core.
- a Part of the coil winding preferably extends along a partial circumference around the coil core, in particular the toroidal core. It was recognized that partial coil turns which have at least one inner conductor can also contribute to a large extent to the formation of inductance in the choke coil.
- the holding body has an insulating layer or an insulating material which is designed to electrically isolate the outer conductors and / or the inner conductors from the toroidal core.
- the insulating layer preferably forms an insulating jacket surrounding the toroidal core.
- the common mode choke can thus advantageously be designed to be voltage-proof, in particular high-voltage-proof.
- a high voltage in particular for automotive applications, for example electric vehicle or hybrid vehicle applications, is between a few hundred volts and a thousand volts, for example.
- the outer conductor of a coil turn is connected to the inner conductor via a connecting section, the connecting section being designed in the shape of a segment of a circle.
- a surface area of the toroidal core can advantageously also be enclosed by a coil turn or partial coil turn, which extends between the opening wall area and a radially outwardly facing outer surface of the toroidal core.
- the surface area is preferably circular and has a circular area which extends between a diameter of the opening and an outer diameter of the ring core.
- the turns or partial turns of the coil and the further coil for filling the opening and / or for enclosing the toroidal core, when joined together form a shape of a cup.
- the aforementioned connecting section forms a cup base
- the outer conductors form an outer cup wall
- the inner conductors form a cylinder or pin which extends in particular centrally from the cup base into the cavity enclosed by the outer conductors and thus the cup wall.
- An insulation gap or an insulation material, in particular a plastic material preferably extends between the coil windings.
- the partial turn is preferably U-shaped in one section. More preferably, the inner conductor and the outer conductor each form a U-leg, the connecting section forming a U-bottom connecting the U-legs.
- the outer conductor and a connecting section formed thereon forms a cup segment, the connecting section forming a cup bottom segment.
- the cup segments of all coil part turns of the common mode choke can thus together form a type of cup.
- the cup is preferably designed to receive the toroidal core.
- the outer conductors and / or the inner conductors each have a molded solder foot for soldering to a circuit carrier.
- the solder feet each have a contact surface, the contact surfaces being arranged in a common connecting plane.
- the common-mode choke can thus be reflow-soldered to a circuit carrier of planar design.

- DCB Direct Copper Bonded
- AMB Active Metal Brazed
