[0001] The present invention relates to an electronic assembly, in particular an electronic power assembly, for a hybrid vehicle or an electric vehicle having the features of the preamble of independent claim 1.

Background Art

[0002] In a hybrid vehicle or an electric vehicle, an inverter structure and a converter structure including a commutation circuit composed of an intermediate circuit capacitor and a half bridge, which are formed, for example, in a power module, are used. For example, an inverter that provides a phase current for an electric machine is used for the operation of the electric machine.

[0003] Regarding this, the power module is controlled via a printed circuit board that is in conductive contact with the power module.

Summary of the Invention

[0004] According to the present invention, there is proposed an electronic assembly, in particular an electronic power assembly, for a hybrid vehicle or an electric vehicle. This electronic assembly includes a first printed circuit board having an upper surface and a lower surface opposite to the upper surface, and the first printed circuit board is provided with a plug connector for electrical contact of the first printed circuit board. The electronic assembly further includes an electronics unit, in particular a power electronics unit, which is arranged on the lower surface side of the first printed circuit board and is electrically contacted by a flexible second printed circuit board. The flexible second printed circuit board includes a coupling region having a plug-in region, and the plug-in region of the flexible second printed circuit board is plugged into the plug connector of the first printed circuit board in the plug-in direction, whereby the electronics unit is in electrical contact with the first printed circuit board. The plug connector of the first printed circuit board is arranged on the lower surface side of the first printed circuit board, and the coupling region of the flexible second printed circuit board includes at least one gripping region. The gripping region protrudes beyond the plug-in region in the plug-in direction, and in this regard, the gripping region protrudes from the lower surface of the first printed circuit board to the upper surface of the first printed circuit board through a hole in the first printed circuit board. [Advantages of the Invention] Compared to the prior art, the electronic assembly according to the invention has the advantage that the first printed circuit board can be coupled and electrically contacted with the electronics unit particularly simply and well. In this regard, the electronics unit is electrically contacted with the first printed circuit board via a flexible second printed circuit board. In this electronic assembly, it is advantageous that this can be done on the lower surface side of the first printed circuit board facing the electronics unit. It is advantageous that the insertion region of the flexible second printed circuit board can be inserted into the insertion connector of the first printed circuit board on the lower surface of the first printed circuit board. Through the holes in the first printed circuit board, the coupling region of the flexible second printed circuit board with the gripping region protruding from the lower surface of the first printed circuit board to the upper surface of the first printed circuit board can also be gripped on the upper surface side of the first printed circuit board. Thereby, the insertion region of the flexible second printed circuit board can be inserted into the insertion connector of the first printed circuit board on the lower surface of the first printed circuit board by pulling the gripping region on the upper surface side of the first printed circuit board. The insertion region and the insertion connector are arranged between the first printed circuit board and the electronics unit and are inaccessible and invisible or difficult to access and difficult to see. Nevertheless, due to the gripping region on the upper surface side of the first printed circuit board, the insertion region can be inserted into the insertion connector. Therefore, "blind fitting" of the insertion region into the insertion connector is possible. The holes in the first printed circuit board have already aligned the coupling region having the insertion region in the direction of the insertion connector. Therefore, by pulling the gripping region away from the upper surface of the first printed circuit board, the insertion region can be inserted into the insertion connector. Although the insertion plug and the insertion connector are arranged on the lower surface side of the first printed circuit board, it is advantageous that the insertion process of the insertion region into the insertion connector can be carried out from the upper surface side of the first printed circuit board. The upper surface of the printed circuit board is clearly more accessible for this process. This process cannot be carried out directly on the lower surface side of the first printed circuit board because the electronics unit makes access difficult or prevents it there.That is, it is even more advantageous that the plug connector can be arranged on the lower surface side of the first printed circuit board, and the insertion region of the flexible second printed circuit board can be inserted from the lower surface side of the first printed circuit board, so that the electronic assembly can be formed compactly. In this case, it is not necessary to guide the insertion region of the flexible second printed circuit board through the first printed circuit board or past the side of the first printed circuit board so as to be inserted into the plug connector on the upper surface side of the first printed circuit board. Thus, it is advantageous that the area of the first printed circuit board is reduced, and it is advantageous that the first printed circuit board can be formed compactly.

[0005] Further advantageous forms and modifications of the present invention are made possible by the features presented in the dependent claims. According to one advantageous exemplary embodiment, at least two gripping regions are formed on the flexible second printed circuit board, and it is contemplated that the insertion region and the plug connector of the flexible second printed circuit board are arranged between the gripping regions of the second printed circuit board. For example, the insertion region can be inserted straight and reliably into the plug connector by two gripping regions that protrude from the lower surface of the first printed circuit board to the upper surface of the first printed circuit board through holes in the first printed circuit board, respectively. The coupling region can be gripped by both gripping regions on both sides of the insertion region and the plug connector, and can be pulled away from the upper surface of the first printed circuit board, whereby the insertion region is inserted into the plug connector.

[0006] According to one advantageous exemplary embodiment, it is contemplated that the insertion region and / or the gripping region are formed as rigid regions of the flexible second printed circuit board. Thus, the gripping region and the insertion region are rigidly coupled to each other, and the direction in which the insertion region is inserted into the plug connector corresponds to the direction in which the coupling region is pulled by the gripping region. In this way, the insertion region can be surely and well aligned on the lower surface side of the first printed circuit board by the gripping region on the upper surface side of the first printed circuit board and can be inserted into the plug connector.

[0007] According to one advantageous exemplary embodiment, a centering device is arranged between the first printed circuit board and the electronics unit, and the flexible second printed circuit board is guided through the centering opening of the centering device, in particular in the insertion direction, whereby the insertion area of the flexible second printed circuit board is aligned. In this case, at least one centering element is formed on the centering device, the centering element is in contact with the first printed circuit board, and it is contemplated that the first printed circuit board is aligned with the centering device via the centering element. It is advantageous that the centering device enables the connection area of the flexible second printed circuit board to be well positioned relative to the first printed circuit board and the electronics unit. The centering opening in the centering device positions the insertion area in the correct place and aligns it in the insertion direction with respect to the insertion connector. The centering element aligns the first printed circuit board, and thus the insertion connector on the lower side of the first printed circuit board, with respect to the insertion area of the flexible second printed circuit board.

[0008] According to one advantageous exemplary embodiment, it is contemplated that the centering element is formed as a pin that protrudes through an alignment opening formed in the first printed circuit board. Thus, the first printed circuit board can be aligned with respect to the centering device and the insertion area of the flexible second printed circuit board by the centering element, for example when being mounted on the centering device.

[0009] According to one advantageous exemplary embodiment, it is contemplated that the centering device is formed as a plate, in particular as a support plate for the first printed circuit board. Thus, the centering device serves on the one hand as a support plate for the first printed circuit board and on the other hand aids in aligning the insertion area of the flexible second printed circuit board with respect to the first printed circuit board, and thus the insertion connector of the first printed circuit board.

[0010] According to one advantageous exemplary embodiment, it is contemplated that a holding device for holding and aligning a coupling region of a flexible second printed circuit board is formed in the electronics unit. By means of this holding device, it is advantageous that the coupling region of the flexible second printed circuit board can be aligned and held in the direction of the plug connector before the insertion region is inserted into the plug connector.

[0011] According to one advantageous exemplary embodiment, the coupling region of the flexible second printed circuit board is held by the holding device and aligned in the insertion direction in a first position, and the coupling region of the flexible second printed circuit board is intended to be removable from the holding device by pulling the gripping region in the insertion direction. That is, the coupling region may be aligned in a first position for placing the centering device on the electronics unit, and when the centering device is placed on the electronics unit, the coupling region of the flexible second printed circuit board is passed through a centering opening in the centering device.

[0012] According to one advantageous exemplary embodiment, the holding device includes a first holding part and a second holding part, the first holding part and the second holding part being separated by a gap, and the coupling region of the flexible second printed circuit board can be sandwiched in the gap between the first holding part and the second holding part, whereby it is contemplated that the coupling region is held by the holding device and aligned in the insertion direction. In this way, a holding device is provided that aligns the coupling region in the direction of the centering opening in the centering device and in the direction of the plug connector before the insertion region is inserted into the plug connector. In this case, when the gripping region is pulled, the coupling region of the flexible second printed circuit board is pulled out of the gap between the first holding part and the second holding part, and the insertion region can be inserted into the plug connector in the process. Accordingly, when the insertion region is inserted into the plug connector, the holding device no longer holds the coupling region.

[0013] According to one advantageous exemplary embodiment, fitting elements are formed on the first holding part and / or the second holding part, the fitting elements protruding into the gap, in which case fitting openings complementary to the fitting elements are formed in the bonding region of the flexible printed circuit board, and it is contemplated that the fitting elements can be fitted into the fitting openings. The fitting elements are used for holding the bonding region in the holding device, advantageously ensuring that the bonding region cannot be detached from the holding device other than by pulling the gripping region when inserting the insertion region into the plug connector.

Embodiments for Carrying Out the Invention

[0016] The electronic assembly 1 according to the present invention is applicable in a wide variety of ways and can be applied, for example, as an inverter or converter in automotive technology. For example, this electronic assembly can be formed not only as an inverter, also called an inverter, but also, for example, for the operation of an electric machine in a hybrid vehicle or an electric vehicle.

[0017] FIG. 1 shows one exemplary embodiment of the electronic assembly 1. FIG. 2 shows a sectional view belonging to the exemplary embodiment of the electronic assembly based on FIG. 1. The electronic assembly 1 includes a first printed circuit board 10 having an upper surface 11 and a lower surface 12 opposite to the upper surface 11. The electronic assembly 1 further includes a flexible second printed circuit board 30 and an electronics unit 20. The first printed circuit board 10 is used, for example, for controlling the electronics unit 20. The flexible second printed circuit board 30 is in electrical contact with both the first printed circuit board 10 and the electronics unit 20. The conductor paths of the flexible second printed circuit board 30 are used, for example, for transmitting signals for controlling the electronics unit 20.

[0018] The electronics unit 20 can be, for example, a power electronics unit. In this exemplary embodiment, the electronics unit 20 includes a molded housing. For example, a carrier substrate is disposed within the housing, and electrical components and / or electronic components are disposed on the carrier substrate. The carrier substrate can be, for example, a circuit board, a DBC substrate (Direct Bonded Copper) in this exemplary embodiment. However, the carrier substrate may be, for example, an AMB substrate (Active Metal Brazed), an IMS (Insulated Metal Substrate), a printed circuit board (PCB), or another substrate suitable for a power module. Various electrical components and / or electronic components, such as power semiconductors, for example, field effect transistors such as MIS-FET (Metal Insulated Semiconductor Field Effect Transistor), IGBT (insulated-gate bipolar transistor), power MOSFET (metal oxide semiconductor field-effect transistor), and / or diodes, for example, rectifier diodes, can be disposed on the carrier substrate. Passive components, such as resistors or capacitors, for example, can also be further disposed on the carrier substrate as electrical components and / or electronic components. The carrier substrate can further include conductor paths not shown in the figures. The conductor paths of the carrier substrate can be formed as conductor surfaces capable of passing high currents, as in this exemplary embodiment. The electrical components and / or electronic components can be conductively coupled to each other or to further electrical and / or electronic elements not shown in the figures disposed outside the electronics unit 20, for example, by soldering or sintering, via conductor paths of the carrier substrate, bonding wires, or other suitable conductive contact elements. The electronics unit 20 has a connection portion that electrically contacts the electronics unit 20 by means of a flexible second printed circuit board 30.

[0019] The electronic assembly 1 may further include a cooling body (not shown in the figures), and the cooling body cools the electronics unit 20. The cooling body may be made of, for example, a material with excellent thermal conductivity, such as aluminum or copper. The cooling body may be formed, for example, as a plate. The cooling body may have structures formed thereon, such as ribs, pins, or flow channels, for example, to improve heat dissipation.

[0020] The electronic assembly 1 further includes a first printed circuit board 10. The first printed circuit board 10 has an upper surface 11 and a lower surface 12 opposite the upper surface 11. In the electronic assembly 1, the lower surface 12 of the first printed circuit board 10 is arranged to face the electronics unit 20. The first printed circuit board 10 can be, for example, a rigid printed circuit board, such as a printed circuit board of a grade of FR4 or higher, that is, a printed circuit board made of, for example, glass fiber-reinforced epoxy resin. However, the first printed circuit board 10 may be an HDI printed circuit board (High Density Interconnect printed circuit board), LTCC (Low Temperature Cofired Ceramics), or another suitable rigid or flexible printed circuit board. The first printed circuit board 10 includes, for example, one or more electrical components and / or electronic components (not shown in the figures) that are interconnected by conductor paths (not shown in the figures) and together constitute, for example, a control circuit for the electronics unit 20.

[0021] The insertion connector 40 is arranged on the first printed circuit board 10. The insertion connector 40 is provided for electrical contact of the first printed circuit board 10. For this purpose, an insertion area 32 can be inserted into the insertion connector 40. Inside the insertion connector 40, there are a number of contact parts provided for contacting the conductor paths of the flexible second printed circuit board 30. The contact parts inside the insertion connector 40 are used for electrical contact of the first printed circuit board 10. When the insertion area 32 of the second flexible printed circuit board 30 is inserted into the insertion connector 40, an electrical connection is established between the contact parts inside the insertion connector 40 and the conductor paths of the second flexible printed circuit board 30. In this exemplary embodiment, the printed circuit board 10 is formed as a control circuit provided for controlling the electronics unit 20. For this purpose, the contact parts inside the insertion connector 40 of the printed circuit board 10 are conductively connected to the connection parts of the electronics unit 20 by the flexible second printed circuit board 30. The insertion connector 40 is arranged on the lower surface 12 side of the first printed circuit board 10. The insertion connector 40 faces the electronics unit 20. The insertion connector 40 is fixed to the lower surface 12 of the first printed circuit board 10. The insertion connector 40 protrudes from the lower surface 12 of the first printed circuit board towards the electronics unit 20. The insertion connector 40 has a receiving opening facing the electronics unit 2 for receiving the insertion area 32 of the second flexible printed circuit board 30. The insertion connector 40 can be formed, for example, as an FPC insertion connector.

[0022] The electronic assembly 1 further includes a flexible second printed circuit board 30. The flexible second printed circuit board 30 can be formed, for example, as an FPC (flexible printed circuit), especially as an FPC connector. The flexible second printed circuit board 30 has, for example, a considerable flexibility with plasticity. The flexible second printed circuit board 30 is used for the connection of the electronic assembly. Here, the electronic assembly arranged on the first printed circuit board 10 and the electronics unit 20 are connected by the second flexible printed circuit board 30. The flexible second printed circuit board 30 may, for example, include a printed circuit, which is formed on a flexible plastic support, such as polyimide, Mylar, nylon, or polyester film. As the conductor material, for example, copper can be used. The contact area may be, for example, gold-plated. The flexible second printed circuit board 30 has an area arranged on the electronics unit 20, in which area the flexible second printed circuit board 30 is electrically connected to the connection part of the electronics unit 20. The flexible second printed circuit board 30 can be, for example, welded to the connection part of the electronics unit 20.

[0023] The flexible second printed circuit board 30 further has a coupling region 31, by which the flexible second printed circuit board 30 is electrically coupled to the first printed circuit board 10. The coupling region 31 of the second flexible printed circuit board 10 includes an insertion region 32 and at least one gripping region 33. In the illustrated exemplary embodiment, the coupling region includes one insertion region 32 and two gripping regions 33. The insertion region 32 is disposed between both gripping regions 33. The insertion region 32 is formed for electrical contact between the flexible second printed circuit board 30 and the insertion connector 40 of the first printed circuit board 10. For this purpose, contact portions are formed in the insertion region 32 of the flexible second printed circuit board 30. The contact portions of the insertion region 32 of the flexible second printed circuit board 30 are, for example, the ends of conductor paths within the flexible second printed circuit board 30. The insertion region 32 of the flexible second printed circuit board 30 is inserted into the insertion connector 40 of the first printed circuit board 10 in the insertion direction R. Thereby, the contact portions of the insertion region 32 are in conductive contact with the contact portions of the insertion connector 40, and thus the flexible second printed circuit board 30 is conductively coupled to the first printed circuit board 10. The insertion direction R represents the direction in which the insertion region 31 of the flexible second printed circuit board 30 is inserted into the insertion connector 40. The insertion direction R is, for example, perpendicular to the first printed circuit board 10.

[0024] The insertion region 32 and the gripping regions 33 are each formed, for example, planar and extend planar within the same plane. The insertion region 32 and the gripping regions 33 extend in the insertion direction R. The insertion region 32 is formed, for example, substantially rectangular. The gripping regions 33 are each formed, for example, tongue-shaped. The insertion region 32 and the gripping regions 33 are formed within the same plane, and the insertion region 32 is disposed within the plane between both gripping regions 33. The gripping regions 33 extend in the insertion direction R beyond the insertion region 32. At the end of the gripping region 33 disposed on the upper surface 11 side of the first printed circuit board 10, a structure may be formed to facilitate gripping of the gripping region 33. In the exemplary embodiment shown here, holes into which a gripper can engage are each formed in each of the gripping regions 33. The coupling region 31 having the insertion region 32 and the gripping regions 33 is formed, for example, substantially fork-shaped.

[0025] The coupling region 31 having the insertion region 32 and the gripping region 33 is one end of the flexible second printed circuit board 30, and at this end, the flexible printed circuit board 30 is coupled to the first printed circuit board 10. The coupling region 31 having the insertion region 32 and the gripping region 33 is formed as a rigid region of the flexible second printed circuit board 30. The flexible second printed circuit board 30 is hardened in the coupling region 31, and thus is formed with rigidity in the coupling region 31. The insertion region 32 is inserted into the insertion connector 40 on the lower surface 12 of the first printed circuit board 10, and thus is disposed on the lower surface 12 side of the first printed circuit board 10. The gripping region 33 protrudes to the upper surface 11 of the first printed circuit board 10 through the hole 13 in the first printed circuit board 10 in the insertion direction R beside the insertion connector 40. One hole 13 is provided in the first printed circuit board 10 for each gripping region 33. In the exemplary embodiment shown here, the printed circuit board 10 includes two holes 13 for the gripping region 33. The insertion connector 40 is disposed between both holes 13. The holes 13 are formed, for example, as slits in the first printed circuit board 10. These slits extend, for example, perpendicular to the insertion direction R and in the direction in which the accommodating portion for the insertion region 32 in the insertion connector 40 also extends. The gripping region 33 protrudes from the hole 13 on the upper surface 11 side of the first printed circuit board 10, and thus the gripping region 33 can be gripped on the upper surface 11 side.

[0026] The electronic assembly 1 further includes a centering device 50. The centering device 50 is disposed between the first printed circuit board 10 and the electronics unit 20. The centering device 50 is formed, for example, in a plate shape. The centering device 50 can also serve as a support plate for the first printed circuit board 10, for example. The flexible second printed circuit board 30 passes through the centering device 50. For this purpose, a centering port 51 is formed in the centering device 50. The centering port 51 is formed, for example, in a slit shape. The flexible second printed circuit board 30 passes through the centering port 51 in the centering device 50, particularly in the insertion direction R. By the flexible second printed circuit board 30 passing through the centering port 51 in the insertion direction R, the bonding region 31 of the flexible second printed circuit board 30 is also aligned in the insertion direction R. The centering device 50 may include an accessory element 55. The accessory element 55 is disposed, for example, within the centering device 50 formed as a plate, and the centering port 51 is formed within the accessory element 55. The centering port 50 can be formed, for example, at least partially in a funnel shape and can become narrower in the insertion direction R as it moves away from the electronics unit 2. Thus, the flexible second printed circuit board 30 can be inserted particularly well and easily into the centering port 51 of the centering device 50 from the side facing the electronics unit 2 of the centering device 50. A protrusion (not shown in the drawings) can be further provided beside the centering port 51, and this protrusion serves to guide and align the flexible second printed circuit board 30 in the insertion direction R.

[0027] The first printed circuit board 10 is aligned by the centering device 50. In this case, the first printed circuit board 10 is aligned by the centering device 50 such that the flexible printed circuit board 30 simultaneously protrudes through the centering opening 51 in the centering device 50 and the hole 13 in the first printed circuit board 10. The centering device 50 is formed with, for example, centering elements 52 formed as pins. The centering element 52 protrudes from the centering device 50 in the insertion direction R towards the first printed circuit board 10. The centering element 52 of the centering device 50 serves to align the first printed circuit board 10 with respect to the centering device 50. The centering element 52 can protrude through, for example, the alignment opening 14 in the first printed circuit board 10. Thus, the first printed circuit board 10 can be aligned by the centering element 52 and thus by the centering device 50.

[0028] The centering device 50 is further aligned with respect to the electronics unit 20. For this purpose, the electronic assembly 1 may include additional components not shown in the figure establishing the connection between the centering device 50 and the electronics unit 2. That is, the electronics unit 2 can be coupled to the centering unit 50, for example, via a cooling body and / or a housing, and thereby be aligned with respect to the centering unit 50.

[0029] The electronics unit 20 may further include a holding device 60. The holding device 60 is formed to hold the flexible second printed circuit board 30 and align it in the insertion direction R. By the holding device 60, the connection region 31 of the flexible second printed circuit board 30 is aligned in the insertion direction R such that the connection region 31 protrudes through the centering port 51 in the centering device 50 and the hole 13 in the first printed circuit board 10. Within the holding device 60, the connection region 31 of the flexible second printed circuit board 30 can be clipped, thereby fixing it to the electronics unit 20 and aligning it in the insertion direction R. When the centering device 50 and the first printed circuit board 10 are mounted above the electronics unit 20, the connection region 31 of the flexible second printed circuit board 30 passes through the centering port 51 of the centering device 50 and the hole 13 in the first printed circuit board 10. When the centering device 50 and the first printed circuit board 10 are mounted in this case, the gripper can grip the gripping region 33 of the connection region 31 on the upper surface 11 side of the first printed circuit board 10 and pull the connection region 31 in the direction of the insertion direction R, whereby the insertion region 32 is inserted into the insertion connector 40. The holding device 60 in the electronics unit 20 is formed such that when the gripping region 33 is pulled, the connection region 31 comes out of the holding device 60 in the insertion direction R. For this purpose, the holding device 60 may include, for example, one or more clips. The holding device may include a first holding portion 61 and a second holding portion 62, for example, as in the exemplary embodiment shown here. The first holding portion 61 and the second holding portion 62 protrude, for example, in the insertion direction R. The first holding portion 61 and the second holding portion 62 are separated from each other by a gap 63. The insertion region 31 of the flexible second printed circuit board 30 is partially disposed in the gap 63 between the first holding portion 61 and the second holding portion 62. The insertion region 31 of the flexible second printed circuit board 30 is disposed, for example, between the first holding portion 61 and the second holding portion 62. Thus, the connection region 31 is held by the holding device 60 and aligned in the insertion direction R.The first holding portion 61 and / or the second holding portion 62 may further be formed with a fitting element 64, for example, a fitting projection. A fitting opening 35 complementary to the fitting element 64 may further be formed in the coupling region 31 of the flexible second printed circuit board 30, and the fitting element 64 can be fitted into the fitting opening 35. The fitting element 64 projects, for example, into the gap 63. When the coupling region 31 is fitted, the coupling region 31 is aligned in the insertion direction R. By pulling the gripping region 33 in the insertion direction R, the coupling region 31 is disengaged from the fitting within the holding device 60, and the insertion region 32 is inserted into the insertion connector 40.

[0030] Of course, still further exemplary embodiments and hybrid forms of the illustrated exemplary embodiments are possible.
