Description
Technical Field
The invention relates to an electrical connection device, a method for producing such a connection device, and a vehicle, in particular a rail vehicle, having such a connection device.
Background
In converters, in particular rail vehicles, using power semiconductor switches or power transistors based on semiconductors with a larger band gap than silicon, in particular based on silicon carbide (SiC) or gallium nitride (GaN), it is necessary, on the one hand, for the functional units of the converter, which are electrically connected to one another, for example, via a dc voltage intermediate circuit, to be decoupled due to the possibly high switching frequency, however, to have a choke with a relatively small inductance for the ac current component, which choke should not be saturated with the dc current component, on the other hand.
Disclosure of Invention
The object of the present invention is therefore to provide an electrical connection device which meets the requirements and can be produced cost-effectively.
According to the invention, the above-mentioned technical problem is solved by a connection device with a planar choke according to the features of independent claim 1. The connecting device is designed in the dependent claims.
According to the invention, the planar choke of the electrical connection device comprises a spiral device, wherein the spiral device comprises a first and a second planar conductor rail each of which is formed in a spiral shape, wherein the conductor rails are arranged parallel to one another at a distance from one another, wherein the first conductor rail is rotated helically inwards from an outer connection end of the connection device in a predetermined direction of rotation and forms an inner connection end in an inner region of the spiral device, wherein the outer connection end of the first conductor rail forms a first connection end of the connection device, wherein the second conductor rail is rotated helically outwards from the inner connection end in the inner region of the spiral device in the same direction of rotation and forms an outer connection end of the connection device, wherein the outer connection end of the second conductor rail forms a second connection end of the connection device, and wherein the inner connection ends of the first and second conductor rails are electrically connected by means of a connection element.
Advantageously, a cost-effective and space-efficient construction can be achieved by means of the planar conductor tracks for the choke. In particular, a cost-effective and reliably reproducible structure can be achieved, i.e. a commercially available planar conductor rail can be used, as it is already used for example for low-inductance electrical connections between modules of power semiconductor switches in converters. Furthermore, the choke is advantageously constructed in the form of a so-called air coil without a magnetizable core, whereby saturation due to direct current components is avoided.
The choke structure according to the invention advantageously achieves a small inductance value, for example in the range between 1 muh and 20 muh, in particular in the range 1 muh to 10 muh. It can thus be used, for example, as an inductive decoupling element which generates only small heat loss during operation. The connection device is therefore particularly suitable for use in switching devices with fast-switching power semiconductor switches, for example at the output of a DC/DC converter equipped with such a power semiconductor switch, for example in a SiC power transistor.
According to a further development of the connection device, the sides of the first and second conductor tracks facing each other are mechanically connected by means of an electrically insulating intermediate element, in particular a non-conductive plate, film or lacquer coating. Such an intermediate element can be used to advantage in addition to electrical insulation for stabilizing the spiral device and in particular to avoid that the conductor tracks deform under the influence of external mechanical forces and are pressed to form an electrical short circuit when they are electrically insulated from each other only by a spacing or an air layer.
The two conductor tracks forming the spiral device are preferably each coated, in particular laminated, with an electrically non-conductive material on their side facing away from the other conductor track, in order to ensure electrical insulation from one another.
The conductor rail or the metal sheet used for producing the conductor rail preferably has a thickness of 0.5mm to 10mm, with a thickness of between 2 and 6mm being particularly preferably used or a thickness of 4mm being particularly preferably used. Copper and aluminum are particularly suitable as materials for the metal plates used.
In particular, the two conductor rails can be identically designed, wherein one of the conductor rails is rotated 180 degrees during assembly, so that the same sides are opposite in the initial position. It must be noted here, however, that the continuity of the helical rotation direction remains unchanged after installation.
According to a further development of the connection device, the electrical connection element forms a mechanical spacer which mechanically and electrically connects the inner connection ends of the first and second conductor tracks in the inner region of the spiral device and maintains the spacing.
According to a further development of the connection device, the first and the second connection end are arranged on a common connection side of the connection device.
The connection device or the spiral device thus forms two poles in the form of an inductance with two connection ends, one of which is formed by the outer connection end of the first conductor rail and the other of which is formed by the outer connection end of the second conductor rail.
According to a further development of the connection device, the connection device comprises a third planar conductor rail, wherein the outer connection end of the first conductor rail is arranged on a first connection side of the connection device and the outer connection end of the second conductor rail is arranged on a second connection side of the connection device opposite the first connection side, and wherein the first connection end of the third conductor rail is arranged on the first connection side of the connection device and the second connection end of the third conductor rail is arranged on the second connection side of the connection device.
The connection device forms a quadrupole with four connection ends on the first and second connection sides, wherein an electrical connection is formed between the connection sides by means of the spiral device and another electrical connection is formed between the connection sides by means of the third conductor track. In particular, the third conductor track can be designed such that it influences the magnetic field of the spiral device in a desired manner, so that the resulting inductance of the spiral device can be reproducibly achieved within narrow tolerances.
According to a further development of the connection device, the third conductor track is in the same plane as the first or second conductor track of the spiral device.
Preferably, the metal plate used to manufacture the third conductive rail may correspond to the metal plates of the first conductive rail and the second conductive rail.
The above-mentioned technical problem is likewise solved by a method for producing a connecting device, in particular a connecting device according to the invention. In this case, a first spiral-shaped planar conductor rail and a second spiral-shaped planar conductor rail are produced, which are arranged one above the other in parallel spaced apart relation to one another, such that the first conductor rail rotates helically inwards from an outer connecting end in a predetermined direction of rotation and forms an inner connecting end in an inner region of the spiral device, wherein the outer connecting end of the first conductor rail forms a first connecting end of the connecting device and the second conductor rail rotates helically outwards from the inner connecting end in the inner region of the spiral device in the same direction of rotation and forms the outer connecting end, wherein the outer connecting end of the second conductor rail forms a second connecting end of the connecting device and the inner connecting ends of the first and second conductor rails are electrically connected by means of a connecting element.
According to a further development of the method, the sides of the first and second conductor tracks facing each other are mechanically connected by an electrically insulating intermediate element, in particular a non-conductive plate, film or lacquer coating.
According to a further development of the method, the first conductor rail is produced by stamping or cutting, in particular laser cutting, the first sheet metal and the second conductor rail is produced by stamping or cutting, in particular laser cutting, the second sheet metal and, if present in the connecting device, the third conductor rail is produced by stamping or cutting, in particular laser cutting, the third sheet metal.
According to a further development of the method, the connecting element is designed as a screw or rivet, to which the inner connecting end is mechanically connected.
The above-mentioned object is also achieved by a vehicle, in particular a rail vehicle, having at least one connecting device according to the invention and/or at least one connecting device produced according to the method according to the invention.
According to a further development of the vehicle, the vehicle has a direct voltage intermediate circuit which comprises a first electrical conductor and a second electrical conductor, and in which at least one connecting device according to the invention is electrically integrated into the first and/or the second electrical conductor.
As long as the connection device forms a quadrupole, the connection device divides the direct current intermediate circuit into a first intermediate circuit section and a second intermediate circuit section, and connects the first intermediate circuit section to a first connection side of the quadrupole and the second intermediate circuit section to a second connection side of the quadrupole.
The first intermediate circuit section is connected, for example, to a DC/DC converter on the side facing away from the quadrupole, and the second intermediate circuit section is connected, for example, to an inverter of a converter on the side facing away from the quadrupole. The DC/DC converter may be, for example, a boost converter.

Detailed Description
A method for manufacturing a first embodiment of a spiral device according to the invention is exemplarily described below with reference to fig. 1 to 4.
Fig. 1 shows a first conductor track of a flat spiral 10 of sheet metal, which is produced by stamping or cutting, preferably laser cutting, of sheet metal. The first plate screw 10 rotates helically inward in a clockwise direction starting from the outer screw connection 11, and an inner screw connection 12 of the first plate screw 10 is formed in the screw inner region.
Fig. 2 shows a second conductor track of the plate screw 20, which is likewise embodied as a planar plate screw, and which is likewise produced by stamping or cutting, preferably laser cutting, of a sheet metal material. The second plate screw 20 also rotates outwards helically in a clockwise direction starting from the inner screw connection 22 and forms the outer screw connection 21 externally.
The two plate screws 10 and 20 are placed on top of each other and are connected to each other by means of an electrical connection element 30 in the region of the inner screw connection ends 12 and 22 to form a screw device 40, as shown in fig. 3. The electrical connection element 30 is preferably a screw that threadedly connects the two plates to each other, however alternatively rivets can be used as well.
The electrical connection element 30 has a dual function in an advantageous manner. The connecting element 30 connects the two plate spirals 10 and 20 in the inner region of the spiral on the one hand, and on the other hand, the connecting element 30 serves to keep the two plate spirals 10 and 20 spaced apart outside the connection region or outside the inner spiral connection ends 12 and 22. The spatial arrangement of the two plate screws 10 and 20 can be seen in the section of fig. 4. The distance between the two plate screws 10 and 20 is denoted by reference sign a. Here, the first plate screw 10 is located in a first lower plane E10, and the second plate screw 20 is located in a second plane E20 thereon.
Since the two plate screws 10 and 20 are spatially arranged one above the other, in the embodiment according to fig. 1 to 4 the two external screw connection ends 11 and 21 lie in different planes. Alternatively, one or both of the two external screw connections may be bent in the end region when it should be achieved that the two external screw connections 11 and 21 are arranged in the same plane. Such bending may be advantageous, for example, for connection end reasons.
By the described arrangement of the two plate screws 10 and 20 and the described orientation of the plate screws relative to each other and the screw direction of rotation, it is ensured that the screw direction of rotation is always the same for the current I flowing through the screw device and that the magnetic field generated in the first plate screw 10 has the same magnetic field orientation as the magnetic field generated in the second plate screw 20 and that the magnetic fields overlap constructively, that is to say non-destructively.
The two plate spirals 10 and 20 may advantageously be identical. For example, if the first plate screw 10 according to fig. 1 is also used as the second plate screw 20 according to fig. 2, in the case of an assembly by rotating the plate screw 180 degrees around the longitudinal direction L in fig. 1, only the described continuity of the screw rotation direction is ensured to be obtained after the assembly, remaining one above the other.
A second embodiment of the connection device according to the invention is elucidated below in connection with fig. 5 to 8. Fig. 5 shows a first conductor rail or first plate screw 10, which is exemplarily identical to the first plate screw 10 according to fig. 1. Fig. 6 shows a second conductor rail or second plate screw 20 and additionally a third conductor rail or third plate member 50. The two plate screws 10 and 20 are positioned one above the other and are connected to one another by means of an electrical connection element 30 and form a screw device 40, as described above in connection with fig. 1 to 4. The electrical connection element 30 keeps the two plate screws 10 and 20 spaced apart from each other such that they have a spatial distance a from each other, as shown in fig. 8. Here again, the first plate screw 10 is located in a first lower plane E10 and the second plate screw 20 is located in a second plane E20 above it. The third plate member 50 is placed onto the first plate screw 10 by means of the non-conductive intermediate element 60 and is thereby electrically insulated with respect to the first plate screw.
Fig. 7 shows the resulting spiral device 60 in top view and fig. 8 shows it in cross section.
By the design of the two plate screws 10 and 20, it is also ensured in the second embodiment that the screw direction of rotation for the current I flowing through the screw device 40 is always the same and that the magnetic field generated in the first plate screw 10 has the same magnetic field orientation as the magnetic field generated in the second plate screw 20.
In order to avoid electrically shorting the two plate screws 10 and 20 to one another outside their connection area or outside the connection element 30 due to external influences, for example mechanical loads, a non-conductive intermediate element, which is shown for example in fig. 9 and is denoted there by the reference numeral 70, can be used between the two plate screws 10 and 20 in the first and second exemplary embodiments.
Furthermore, it can be provided that the outer sides of the two plate screws 10 and 20 are coated with an electrically non-conductive material. For example, the outer sides of the two plate screws 10 and 20 may be laminated with a film as exemplarily shown in fig. 10 and denoted by reference numeral 80.
Alternatively or in addition to the intermediate element 70 shown in fig. 9, a coating, for example in the form of a non-conductive film, can also be provided on the inner sides of the two plate screws 10 and 20 in order to avoid short circuits outside the area of the electrical connection element 30. An inner coating in the form of such a non-conductive film 90 is shown schematically in fig. 11.
Fig. 12 shows an embodiment for a rail vehicle 100 which is equipped with a direct voltage intermediate circuit 110. In the embodiment according to fig. 12, a direct voltage intermediate circuit 110 connects a DC/DC converter 120 and a converter or inverter 130. The converter 130 can be connected to a drive component, which is not shown in fig. 12 for reasons of overview, in particular to one or more drive motors of the rail vehicle 100.
In one of the two conductors of the dc intermediate circuit 110, for example the conductor 111 above in fig. 12 having a positive voltage potential, the spiral device 40 according to fig. 1 to 4 is connected in the middle. The spiral device forms two poles, which divide the electrical conductor 111 into two sections 111a and 111b.
The spiral device 40 serves as a choke which interacts electrically with the capacitors C1 and C2 or a so-called intermediate circuit capacitor. The capacitors C1 and C2 may be separate components disposed in the direct current intermediate circuit 110 as exemplarily shown in fig. 12, or may be configured as constituent parts of the DC/DC converter 120 or the inverter 130.
Fig. 13 shows a further embodiment of a rail vehicle 100, in which the connection device according to fig. 5 to 8 is connected between two electrical conductors 111 and 112 of a direct voltage intermediate circuit 110. The spiral device 40 forms a quadrupole 210, which electrically divides the direct current intermediate circuit 110 into a first intermediate circuit section 110a and a second intermediate circuit section 110b. The upper current conductor 111 is in turn connected to the spiral device 40 with a positive voltage potential, while the lower current conductor 112 is connected to the third plate part 50 or the third current rail with, for example, a negative or ground potential. The connection device can thus advantageously be integrated in a simple manner into the two electrical conductors 111, 112 of the direct-current intermediate circuit.
The quadrupole 210 forms a first connection end 211a of the quadrupole 210 on a first connection side 211 on the left in fig. 13 with an external screw connection end of one of the two plate screws, and forms a first connection end 212a of the quadrupole 210 on a second connection side 212 on the right with an external screw connection end of the other of the two plate screws. The second connection end 211b on the first connection side 211 of the quadrupole 210 and the second connection end 212b on the second connection side 212 of the quadrupole 210 are formed by or at least connected to each other by means of a third plate member 50 corresponding to fig. 5 to 8.
