Description
Technical Field
[0001] The invention relates to an electronic component, in particular an electronic power component for a hybrid vehicle or an electric vehicle, having the features of the preamble of independent claim 1 . Background Art
[0002] In hybrid vehicles or electric vehicles, inverter structures and converter structures are used, which have a rectifier circuit formed by an intermediate circuit capacitor and a half bridge, which is formed in a power module, for example. For example, an inverter is used to operate an electric motor, which provides phase currents for the electric motor.
[0003] In this case, the power module is actuated via a printed circuit board which is in electrically conductive contact with the power module. Summary of the invention
[0004] According to the invention, an electronic component is proposed, in particular an electronic power component for a hybrid vehicle or an electric vehicle. The electronic component comprises a first circuit board having an upper side and a lower side facing away from the upper side, wherein a plug connector for electrically contacting the first circuit board is arranged on the first circuit board. The electronic component also comprises an electronic unit, in particular a power electronic unit, wherein the electronic unit is arranged on the lower side of the first circuit board, wherein the electronic unit is electrically contacted via a flexible second circuit board, wherein the flexible second circuit board comprises a connection area with a plug area, wherein the plug area of the flexible second circuit board is inserted into the plug connector of the first circuit board in a plug direction, and the electronic unit is thus electrically contacted with the first circuit board, wherein the plug connector of the first circuit board is arranged on the lower side of the first circuit board, wherein the connection area of the flexible second circuit board comprises at least one gripping area, wherein the gripping area protrudes beyond the plug area in the plug direction, wherein the gripping area protrudes from the lower side of the first circuit board toward the upper side of the first circuit board through a gap in the first circuit board.
[0005] Compared with the prior art, the electronic assembly according to the present invention has the following advantages: the first circuit board can be particularly easily and well connected and electrically contacted with the electronic unit. Here, the electronic unit is electrically contacted with the first circuit board through the flexible second circuit board. In the current electronic assembly, this can be advantageously achieved on the lower side of the first circuit board facing the electronic unit. The plug-in area of the flexible second circuit board can advantageously be inserted into the plug connector of the first circuit board at the lower side of the first circuit board. Through the gripping area protruding from the lower side of the first circuit board through the gap of the first circuit board toward the upper side of the first circuit board, the connection area of the flexible second circuit board can also be gripped at the upper side of the first circuit board. Therefore, by pulling at the gripping area at the upper side of the first circuit board, the plug-in area of the flexible second circuit board can be inserted into the plug connector of the first circuit board at the lower side of the first circuit board. The plug-in area and the plug connector are arranged between the first circuit board and the electronic unit and cannot or only difficult to reach and see. Through the gripping area on the upper side of the first circuit board, the plug-in area can still be inserted into the plug connector. Therefore, the plug-in area can be "blindly connected" to the plug connector. Through the gap in the first circuit board, the connection area with the plug area has been aligned in the direction of the plug connector. Therefore, by pulling the grip area away from the upper side of the first circuit board, the plug area can be inserted into the plug connector. The process of inserting the plug area into the plug connector can be advantageously performed from the upper side of the first circuit board, although the plug and the plug connector are arranged on the lower side of the first circuit board. For this process, the upper side of the circuit board is obviously more accessible. This process cannot be carried out directly on the lower side of the first circuit board because the electronic unit there makes it difficult or hinders access. Therefore, the electronic component is also advantageously compactly designed because the plug connector can be arranged on the lower side of the first circuit board and the plug area of the flexible second circuit board can be inserted from the lower side of the first circuit board. The plug area of the flexible second circuit board does not have to be guided through or through the first circuit board to the upper side of the first circuit board, so as to be subsequently inserted into the plug connector of the first circuit board on the upper side of the first circuit board there. This advantageously saves area on the first circuit board and can be advantageously compactly constructed.
[0006] Further advantageous embodiments and improvements of the invention are possible by means of the features specified in the dependent claims.
[0007] According to an advantageous embodiment, at least two gripping areas are formed on the flexible second circuit board, wherein the plugging area of the flexible second circuit board and the plug connector are arranged between the gripping areas of the second circuit board. The plugging area can be inserted directly and reliably into the first plug connector by means of the two gripping areas, which for example protrude from the bottom side of the first circuit board toward the top side of the first circuit board through a gap in the first circuit board. The connection area can be gripped at the two gripping areas on both sides of the plugging area and the plug connector and pulled away from the top side of the first circuit board so that the plugging area is inserted into the plug connector.
[0008] According to an advantageous embodiment, it is provided that the plug-in region and / or the gripping region are designed as rigid regions of the flexible second printed circuit board. The gripping region and the plug-in region are thus rigidly connected to one another, and the direction in which the plug-in region is inserted into the plug connector corresponds to the direction in which the connecting region is pulled by the gripping region. The plug-in region can thus be reliably and well aligned on the underside of the first printed circuit board by the gripping region at the upper side of the first printed circuit board and can be inserted into the plug connector.
[0009] According to an advantageous embodiment, a centering device is arranged between the first circuit board and the electronic unit, wherein the flexible second circuit board is guided through a centering opening of the centering device, in particular in the plug-in direction, and the plug-in region of the flexible second circuit board is thus aligned, wherein at least one centering element is formed at the centering device, which is in contact with the first circuit board and by which the first circuit board is aligned with the centering device. By means of the centering device, the connection region of the flexible second circuit board can be advantageously well positioned relative to the first circuit board and the electronic unit. By means of the centering opening in the centering device, the plug-in region is placed in the correct position and aligned with the plug connector in the plug-in direction. By means of the centering element, the first circuit board and therefore the plug connector on the underside of the first circuit board are aligned relative to the plug-in region of the flexible second circuit board.
[0010] According to an advantageous embodiment, the centering element is designed as a pin which projects through an alignment opening formed in the first printed circuit board. Thus, when the first printed circuit board is placed, for example, on the centering device, the first printed circuit board can be aligned at the centering element relative to the centering device and the plug-in area of the flexible second printed circuit board.
[0011] According to an advantageous embodiment, the centering device is designed as a plate, in particular as a carrier plate for the first circuit board. The centering device thus serves, on the one hand, as a carrier plate for the first circuit board and, on the other hand, for aligning the plug-in region of the flexible second circuit board relative to the first circuit board and thus relative to the plug connector of the first circuit board.
[0012] According to an advantageous embodiment, a holding device for holding and aligning the connection region of the flexible second printed circuit board is provided on the electronic unit. By means of the holding device, the connection region of the flexible second printed circuit board can be advantageously aligned and held in the direction of the plug connector before the plug connector is inserted into the plug connector.
[0013] According to an advantageous embodiment, it is provided that the connection region of the flexible second printed circuit board is held in a first position by a holding device and is aligned in the plug-in direction and that the connection region of the flexible second printed circuit board can be released from the holding device by pulling in the plug-in direction at the gripping region. The connection region can thus be aligned in the first position in order to arrange the centering device on the electronic unit, wherein when the centering device is arranged on the electronic unit, the connection region of the flexible second printed circuit board is guided through the centering opening in the centering device.
[0014] According to an advantageous embodiment, it is provided that the holding device comprises a first holding element and a second holding element, wherein the first holding element and the second holding element are spaced apart by a gap, wherein the connection area of the flexible second printed circuit board can be clamped in the gap between the first holding element and the second holding element, so that the connection area is held by the holding device and aligned in the plug-in direction. In this way, a holding device is provided, wherein before the plug-in area is inserted into the plug-in connector, the connection area is aligned in the direction of the centering opening in the centering device and in the direction of the plug-in connector. When pulling at the gripping area, the connection area of the flexible second printed circuit board can then be pulled out of the gap between the first holding element and the second holding element, and the plug-in area is inserted into the plug-in connector. If the plug-in area is inserted into the plug-in connector, the holding device therefore no longer holds the connection area.
[0015] According to an advantageous embodiment, a locking element is formed on the first and / or second retaining element and projects into the gap, wherein a locking opening complementary to the locking element is formed on the connection region of the flexible printed circuit board and the locking element can be locked in the locking opening. The locking element serves to retain the connection region on the retaining device and advantageously ensures that when the plug region is inserted into the plug connector, the connection region can be released from the retaining device only by pulling on the gripping region.

DETAILED DESCRIPTION
[0021] The electronic component 1 according to the invention can be used in various ways, for example as an inverter or converter in motor vehicle technology. For example, the electronic component can be designed as an inverter, which is also called a converter and is used, for example, for operating an electric machine of a hybrid or electric vehicle.
[0022] Figure 1 An embodiment of an electronic assembly 1 is shown. Figure 2 Shows Figure 1 1 shows a cross section of an embodiment of an electronic assembly in FIG. The electronic assembly 1 comprises a first printed circuit board 10 having an upper side 11 and a lower side 12 facing away from the upper side 11. In addition, the electronic assembly 1 comprises a flexible second printed circuit board 30 and an electronic unit 20. The first printed circuit board 10 is used, for example, to control the electronic unit 20. The flexible second printed circuit board 30 is in electrical contact with both the first printed circuit board 10 and the electronic unit 20. The conductor paths of the flexible second printed circuit board 30 are used, for example, to transmit signals to control the electronic unit 20.
[0023] The electronic unit 20 can be, for example, a power electronic unit. In this embodiment, the electronic unit 20 includes a molded housing. For example, a carrier substrate is arranged in the housing and electrical and / or electronic components are arranged on the carrier substrate. The carrier substrate can be, for example, a circuit carrier, in this embodiment, a DBC substrate (Direct Bonded Copper). However, the carrier substrate can also be, for example, an AMB substrate (Active Metal Brazed), an IMS (Insulated Metal Substrate), a circuit board (PCB, Printed Circuit Board) or other substrates suitable for a power module. Various electrical and / or electronic components can be arranged on the carrier substrate, for example, power semiconductors, such as field effect transistors, such as MIS-FET (metal insulator semiconductor field effect transistor), IGBT (insulated gate bipolar transistor), power MOSFET (metal oxide semiconductor field effect transistor) and / or diodes, such as rectifier diodes. In addition, passive components, such as resistors or capacitors, can also be arranged on the carrier substrate as electrical and / or electronic components. The carrier substrate can also include a conductor circuit not shown in the figure. As in this embodiment, the conductor paths of the carrier substrate can be designed as conductor surfaces that can conduct high currents. The electrical and / or electronic components can be electrically conductively connected to each other, for example, by the conductor paths of the carrier substrate, by bonding wires or other suitable conductive contact elements, for example by welding or sintering, or to other electrical and / or electronic components that are arranged outside the electronic unit 20 and are not shown in the drawings. The electronic unit 20 has connection points, at which the electronic unit 20 is electrically contacted via the flexible second circuit board 30.
[0024] The electronic assembly 1 can also include a cooling body not shown in the drawings, by which the electronic unit 20 is cooled. The cooling body can be made of a material with good thermal conductivity, such as aluminum or copper, for example. The cooling body can be configured as a plate, for example. On the cooling body, a structure for improving heat dissipation, such as ribs, pins or channels, can be configured.
[0025] In addition, the electronic assembly 1 comprises a first circuit board 10. The first circuit board 10 has an upper side 11 and a lower side 12 facing away from the upper side 11. The first circuit board 10 is arranged in the electronic assembly 1 so that the lower side 12 of the first circuit board 10 faces the electronic unit 20. The first circuit board 10 can be, for example, a rigid circuit board, for example, a circuit board with an FR4 embodiment or a higher quality, that is, for example, a circuit board made of glass fiber reinforced epoxy resin. However, the first circuit board 10 can also be an HDI circuit board (high density interconnect circuit board), LTCC (low temperature co-fired ceramic) or other suitable rigid or flexible circuit boards. The first circuit board 10, for example, comprises one or more electrical and / or electronic components, which are connected to each other by conductor circuits not shown in the drawings and are also not shown in the drawings, and together, for example, they form a control circuit for the electronic unit 20.
[0026] A plug connector 40 is arranged on the first circuit board 10. The plug connector 40 is provided for electrical contacting of the first circuit board 10. For this purpose, the plug region 32 can be inserted into the plug connector 40. There are a plurality of contact points in the plug connector 40, which are provided for contacting the conductor circuit of the flexible second circuit board 30. The contact points in the plug connector 40 are used for electrically contacting the first circuit board 10. If the plug region 32 of the flexible second circuit board 30 is inserted into the plug connector 40, an electrical connection is formed between the contact points in the plug connector 40 and the conductor circuit of the flexible second circuit board 30. In this embodiment, the circuit board 10 is designed as a control circuit, which is provided for controlling the electronic unit 20. For this purpose, the contact points in the plug connector 40 of the circuit board 10 are conductively connected to the connection points of the electronic unit 20 through the flexible second circuit board 30. The plug connector 40 is arranged on the lower side 12 of the first circuit board 10. The plug connector 40 faces the electronic unit 20. The plug connector 40 is fastened at the lower side 12 of the first circuit board 10. The plug connector 40 protrudes from the underside 12 of the first circuit board toward the electronic unit 20. To receive the plug region 32 of the flexible second circuit board 30, the plug connector 40 has a receiving opening toward the electronic unit 2. The plug connector 40 can be designed as an FPC plug connector, for example.
[0027] In addition, the electronic component 1 includes a flexible second circuit board 30. The flexible second circuit board 30 can be designed as, for example, an FPC (flexible printed circuit), in particular an FPC connector. The flexible second circuit board 30 has, for example, a significant plastic bending capability. The flexible second circuit board 30 is used to connect the electronic component. Here, the electronic component arranged on the first circuit board 10 is connected to the electronic unit 20 via the flexible second circuit board 30. The flexible second circuit board 30 can, for example, include a printed circuit constructed on a flexible plastic carrier (for example, polyimide, Mylar, nylon or polyester film). For example, copper can be used as a conductor material. For example, the contact area can also be gold-plated. The flexible second circuit board 30 has an area arranged at the electronic unit 20, in which the flexible second circuit board is electrically connected to the connection point of the electronic unit 20. The flexible second circuit board 30 can, for example, be soldered at the connection point of the electronic unit 20.
[0028] Furthermore, the flexible second circuit board 30 has a connection area 31 at which the flexible second circuit board 30 is electrically connected to the first circuit board 10. The connection area 31 of the flexible second circuit board 10 includes a plug-in area 32 and at least one gripping area 33. In the embodiment shown in the drawings, the connection area includes a plug-in area 32 and two gripping areas 33. The plug-in area 32 is arranged between the two gripping areas 33. The plug-in area 32 is designed to electrically contact the flexible second circuit board 30 with the plug connector 40 of the first circuit board 10. For this purpose, a contact point is formed at the plug-in area 32 of the flexible second circuit board 30. The contact point at the plug-in area 32 of the flexible second circuit board 30 is, for example, an end of a conductor track in the flexible second circuit board 30. The plug-in area 32 of the flexible second circuit board 30 is inserted into the plug connector 40 of the first circuit board 10 along the plug-in direction R. Therefore, the contact point of the plug-in area 32 is in conductive contact with the contact point of the plug connector 40, and the flexible second circuit board 30 is thus conductively connected to the first circuit board 10. The plug-in direction R indicates the direction in which the plug-in region 31 of the flexible second printed circuit board 30 is plugged into the plug connector 40. The plug-in direction R is perpendicular to the first printed circuit board 10, for example.
[0029] The plug-in area 32 and the gripping area 33 are each designed as a flat surface. And extend in the same plane. The plug-in area 32 and the gripping area 33 extend along the plug-in direction R. The plug-in area 32 is, for example, substantially rectangular. The gripping area 33 is, for example, tongue-shaped. The plug-in area 32 and the gripping area 33 are formed in the same plane, wherein the plug-in area 32 is arranged in the plane between the two gripping areas 33. The gripping area 33 extends beyond the plug-in direction R. A structure can be formed at the end of the gripping area 33 arranged on the upper side 11 of the first circuit board 10, which makes it easier to grasp the gripping area 33. In the embodiment shown here, each gripping area in the gripping area 33 is respectively configured with a gap, in which a gripping tool can engage. The connection area 31 having the plug-in area 32 and the gripping area 33 is, for example, substantially forked.
[0030] The connection region 31 with the plug region 32 and the grip region 33 forms the end of the flexible second circuit board 30, at which the flexible circuit board 30 is connected to the first circuit board 10. The connection region 31 with the plug region 32 and the grip region 33 is designed as a rigid region of the flexible second circuit board 30. The flexible second circuit board 30 is reinforced in the connection region 31 and is therefore rigidly configured in the connection region 31. The plug region 32 is inserted into the plug connector 40 at the bottom 12 of the first circuit board 10 and is therefore arranged at the bottom 12 of the first circuit board 10. The grip region 33 protrudes through the recess 13 in the first circuit board 10 toward the top 11 of the first circuit board 10 beside the plug connector 40 in the plug direction R. A recess 13 is provided in the first circuit board 10 for each grip region 33. In the embodiment shown here, the circuit board 10 includes two recesses 13 for the grip region 33. The plug connector 40 is arranged between the two recesses 13. The recess 13 is configured, for example, as a slot in the first circuit board 10. The slot extends, for example, in a direction perpendicular to the plugging direction R, in which direction the receptacle for the plugging region 32 in the plug connector 40 also extends. The gripping region 33 protrudes from the recess 13 on the top side 11 of the first printed circuit board 10 so that it can be gripped on the top side 11.
[0031] Furthermore, the electronic assembly 1 comprises a centering device 50. The centering device 50 is arranged between the first circuit board 10 and the electronic unit 20. The centering device 50 is, for example, plate-shaped. The centering device 50 can also be used, for example, as a carrier plate for the first circuit board 10. The flexible second circuit board 30 extends through the centering device 50. For this purpose, a centering opening 51 is formed in the centering device 50. The centering opening 51 is, for example, slit-shaped. The flexible second circuit board 30 extends through the centering opening 51 in the centering device 50, in particular in the plug-in direction R. Since the flexible second circuit board 30 is guided through the centering opening 51 in the plug-in direction R, the connection area 31 of the flexible second circuit board 30 is also oriented in the plug-in direction R. The centering device 50 can include an additional element 55, which is arranged in the centering device 50, for example, which is formed as a plate, and in which the centering opening 51 is formed. The centering opening 50 can, for example, be at least partially funnel-shaped and become narrower in the plug-in direction R away from the electronic unit 2. Therefore, the flexible second circuit board 30 can be particularly well and easily inserted into the centering opening 51 of the centering device 50 from the side of the centering device 50 facing the electronic unit 2. In addition, a protrusion not shown in the figure can be arranged next to the centering opening 51, which is used to guide and align the flexible second circuit board 30 along the plug-in direction R.
[0032] The first circuit board 10 is aligned with the centering device 50. Here, the first circuit board 10 is aligned with the centering device 50 in such a way that the flexible circuit board 30 protrudes through the centering opening 51 in the centering device 50 and the recess 13 in the first circuit board 10 at the same time. A centering element 52 is configured on the centering device 50, for example, and the centering element is configured as a pin, for example. The centering element 52 protrudes from the centering device 50 in the direction of the first circuit board 10 in the plug-in direction R. The centering element 52 of the centering device 50 is used to align the first circuit board 10 relative to the centering device 50. The centering element 52 can protrude, for example, through the alignment opening 14 in the first circuit board 10. Therefore, the first circuit board 10 can be aligned with the centering element 52 and thus with the centering device 50.
[0033] Furthermore, the centering device 50 is aligned relative to the electronic unit 20. For this purpose, the electronic assembly 1 can include further components, not shown in the figure, which establish a connection between the centering device 50 and the electronic unit 2. Thus, the electronic unit 2 can be connected to the centering unit 50, for example, via a heat sink and / or a housing, and thus be aligned relative to the centering unit.
[0034] Furthermore, the electronic unit 20 can include a holding device 60. The holding device 60 is designed to hold the flexible second printed circuit board 30 and align it in the plug-in direction R. The connection region 31 of the flexible second printed circuit board 30 is aligned in the plug-in direction R by the holding device 60 so that the connection region 31 protrudes through the centering opening 51 in the centering device 50 and the recess 13 in the first printed circuit board 10. The connection region 31 of the flexible second printed circuit board 30 can be clipped into the holding device 60 and thus fastened to the electronic unit 20 and aligned in the plug-in direction R. If the centering device 50 and the first printed circuit board 10 are mounted on the electronic unit 20, the connection region 31 of the flexible second printed circuit board 30 passes through the centering opening 51 of the centering device 50 and the recess 13 in the first printed circuit board 10. If the centering device 50 and the first printed circuit board 10 are subsequently mounted, the gripping tool can grip the gripping region 33 of the connection region 31 at the upper side 11 of the first printed circuit board 10 and pull the connection region 31 in the direction of the plugging direction R so that the plugging region 32 is inserted into the plug connector 40. The holding device 60 at the electronic unit 20 is designed so that when the gripping region 33 is pulled in the plugging direction R, the connection region 31 is released from the holding device 60. For this purpose, the holding device 60 can include one or more clips, for example. The holding device can include, for example, a first retaining member 61 and a second retaining member 62, as in the embodiment shown here. The first retaining member 61 and the second retaining member 62 protrude, for example, in the plugging direction R. The first retaining member 61 and the second retaining member 62 are spaced apart from each other by a gap 63. The plugging region 31 of the flexible second printed circuit board 30 is partially arranged in the gap 63 between the first retaining member 61 and the second retaining member 62. The plugging region 31 of the flexible second printed circuit board 30 is arranged, for example, between the first retaining member 61 and the second retaining member 62. The connection region 31 is thus held by the holding device 60 and aligned in the plug-in direction R. In addition, a locking element 64, such as a locking projection, can be configured on the first holding member 61 and / or the second holding member 62. In addition, a locking opening 35 complementary to the locking element 64 can be configured in the connection region 31 of the flexible second printed circuit board 30, in which the locking element 64 can be locked. For example, the locking element 64 extends into the gap 63. If the connection region 31 is locked, it is aligned in the plug-in direction R. By pulling the gripping region 33 in the plug-in direction R, the connection region 31 is released from the locked state in the holding device 60, and the plug-in region 32 is inserted into the plug connector 40.
[0035] Of course, other embodiments and combinations of the embodiments shown are possible.
