Description
Technical Field
The invention relates to an electronic device, in particular a power electronic device, and to a system having a housing and an electronic device.
Disclosure of Invention
From the prior art, systems are already known in a large number of embodiments, which have a housing with a first and a second housing part and in the interior of which an electronic device is accommodated, and an electronic device with a circuit carrier on which a circuit and electrical connections for the circuit are provided. In principle, it is possible to shield the electronic device from the free environment by means of a metal housing. On the one hand, metal housings are expensive. On the other hand, the region provided with said electrical connection ends still presents problems with regard to shielding. Therefore, shielding boxes have hitherto been provided on the circuit carrier around the electrical connection in order to shield the electrical connection and thus the free environment from the electrical and magnetic fields of the circuit. If a large area of the circuit has to be shielded in this way, for example due to a high electrical power, this is associated with problems with the mounting of the electronic device on the carrier or in the housing.
Disclosure of Invention
The invention is based on this.
The object of the invention is to provide a method for the assembly of an electronic device and a system having a housing and an electronic device, which method allows a wide range of shielding of the electronic circuit of the electronic device and of the system.
This object is achieved by an electronic device, in particular a power electronic device, according to the invention and a system according to the invention having a housing and an electronic device.
The invention relates to an electronic device, in particular a power electronic device, having a circuit carrier on which an electrical circuit and electrical connections for the circuit are provided, wherein the electrical connections are shielded from electric and magnetic fields of the circuit by means of a shielding device, wherein the shielding device has at least two separate shielding sections and the separate shielding sections of the shielding device can be connected to one another when the electronic device is transferred into an assembly position, wherein the separate shielding sections of the shielding device are designed as a shielding wall and a shielding cover, wherein the shielding wall and the shielding cover of the shielding device are mechanically connected to one another and to the circuit carrier such that, in the assembly position of the electronic device, a shielding device is obtained which is closed apart from the side opposite the mounting side of the circuit carrier, wherein the electronic device is accommodated in an interior space of a housing, the housing has a first housing part, wherein a shielding wall mounted on the circuit carrier engages in a groove formed by an edge of the first housing part, so that the first housing part overlaps the shielding wall in a labyrinth-like manner.
The invention further relates to a system having a housing and an electronic device which is accommodated in an interior of the housing, wherein the housing has a first housing part and a second housing part, the electronic device being fastened to the first housing part by means of its circuit carrier, wherein the electronic device is designed according to the invention, wherein a shielding device is provided on the side of the circuit carrier which faces away from the first housing part, and the first housing part and the circuit carrier have shielding means which correspond to one another on their opposite sides and shield the electrical connection terminals from the electrical and magnetic fields of the circuit in the assembled position of the system.
The electronic device according to the invention has the significant advantage, in particular, that even a larger area of the circuit can be effectively shielded and at the same time a versatile and proven reliable assembly technique for mechanically and thermally connecting the electronic device to a carrier, for example a housing, can be retained. The separate shielding sections of the shielding device enable access to the area of the circuit of the electronic device that is otherwise covered by the shielding device during mounting of the electronic device on the carrier, i.e. when the electronic device is transferred into the mounting position. One of the separate shielding sections can be mechanically connected to the circuit carrier in advance, so that an exact positioning of this shielding section of the shielding device, for example in the region of the electrical connection end of the circuit, is facilitated. After the shield section that has been assembled in advance in terms of time, a further separate shield section of the shielding device can be oriented on the previously assembled shield section with the same precision, so that an effective shielding is ensured in the assembled position of the electronic device despite the fact that the shielding device has at least two separate shield sections.
In addition to this, the system according to the invention offers significant advantages: the electrical connection terminals of the circuit (for example in the case of a circuit carrier equipped with electrical components on both sides) are effectively shielded from the electrical and magnetic fields of the circuit in the assembly position of the system, i.e. when the electronic device is assembled in a closed housing. Accordingly, the side of the circuit carrier facing the first housing part in the assembled position of the system can also be used for the circuit.
In principle, the at least two separate shielding sections of the electronic device according to the invention can be freely selected from a wide range of suitable types, sizes, shapes, materials and arrangements. Advantageously, the separate shielding sections of the shielding device are designed as a shielding wall and a shielding cover. This simplifies the production of the shielding device, for example of a metal sheet.
In a particularly advantageous further development of the electronic device according to the invention, it is provided that the separate shielding sections of the shielding device are connected to one another in the assembled position of the electronic device in a releasable, in particular overlapping, manner. In this way, access to the area of the circuit that would otherwise be covered by the shielding device is made possible even after the electronic device has been assembled. Furthermore, the overlapping of the separate shielding sections of the shielding device in the mounting position of the electronic device improves the shielding attenuation of the shielding device.
According to a further advantageous further development of the electronic device according to the invention, it is provided that at least one of the separate shielding sections of the shielding device is designed as a metal component, in particular as a steel plate component. In this way, good shielding attenuation can be achieved in a structurally simple manner even when the wall thickness is small. In particular, steel sheets are very well suited for this on the basis of their material properties. However, it is also conceivable to use metal castings, for example metal diecastings.
In a particularly advantageous further development of the system according to the invention, it is provided that the shielding means of the first housing part is designed as a shielding web and the shielding means of the circuit carrier is designed as a shielding contact surface which is designed in accordance with the shielding web. In this way, the shielding means of the first housing part and the circuit carrier are realized in a structurally simple manner.
According to a further advantageous further development of the system according to the invention, it is provided that the second housing part is designed as a housing cover which can be released from the first housing part in the assembly position of the system. The electronic device according to the invention is thus protected against undesired environmental influences. Furthermore, undesired access to the electronic device by a person is effectively prevented. At the same time, the releasable housing cover allows the desired access to the electronic device even after the system according to the invention has been assembled, i.e. after the system has been transferred into its assembly position in which the electronic device is arranged in the interior of the housing defined by the first housing part and the housing cover connected thereto.
According to a further advantageous further development of the system according to the invention, it is provided that the first housing part overlaps the shielding wall in the assembly position of the system. Thereby, the shielding attenuation in the contact area of the shielding wall and the first housing part is improved.
In principle, the first and second housing parts of the housing can be freely selected from a wide range of suitable options according to the type, size, shape, material, arrangement and according to their mechanical connection to one another. The first housing part is advantageously designed as a metal part, in particular as a die-cast part. In this way, on the one hand, an additional shielding of the circuit is achieved in a structurally simple manner. On the other hand, effective cooling of the circuit can be achieved without additional components. According to a further advantageous further development of the system according to the invention, it is provided that the second housing part is designed as a plastic part. The injection-molded parts and the plastic parts can be produced simply and cost-effectively.
Furthermore, the design of the second housing part as a plastic part offers a weight reduction, which is very advantageous, for example, in motor vehicles. According to a further advantageous further development of the system according to the invention, it is provided that the first housing part and the second housing part are connected to one another via a tongue-and-groove connection, in particular by means of an adhesive arranged between the tongue and the groove. A mechanically reliable and, for example, water-tight connection between the first and second housing part is thereby achieved.

Detailed Description
The electronic device according to the invention and the system according to the invention are explained in more detail below with the aid of fig. 1 to 7. Identical or functionally identical components are denoted by the same reference numerals. In the context of the system according to the invention, only the distinguishing features with respect to the electronic device according to the invention are set forth; in other respects, the embodiments correspond to the electronic device according to the invention and the system according to the invention.
Fig. 1 shows an exemplary embodiment of an electronic device according to the present invention in a partial view. The electronic device according to the invention is designed as a power electronic device, i.e. as a dc converter for a dual-voltage on-board system for a motor vehicle, not shown. The dc transformer has a circuit carrier 2 embodied as an electrical printed circuit board, on which a circuit 4 for dc transformation and an electrical connection 6 embodied as an edge strip made of plastic are provided, which has a terminal 6.1 for the circuit 4. In addition to the mounting surface 2.1 visible in fig. 1 for mounting the electrical component 7, the circuit carrier 2 also has a further mounting surface, not shown in fig. 1, which is arranged on the opposite side of the circuit carrier 2 to the mounting surface 2.1.
A shielding section 8.1 of the shielding device 8, which section extends substantially perpendicularly to the circuit carrier 2 and is designed as a shielding wall, is provided on the circuit carrier 2, wherein the shielding wall 8.1 shields the region of the edge strip 6 from the circuit 4 in a manner to be explained below. The shielding wall 8.1 is made of sheet steel, is chamfered a plurality of times (kanten) and passes through the elongated hole of the circuit carrier 2 with a fastening projection facing the circuit carrier 2 in the position shown in fig. 1. The fastening projection is twisted for mounting the shielding wall 8.1 after the mounting surface of the circuit carrier 2, which is not visible in fig. 1, in such a way that the shielding wall 8.1 is positioned and mechanically fixed on the circuit carrier 2. The fastening projections formed on the shielding wall 8.1 and the elongated holes of the circuit carrier 2 corresponding thereto are not shown.
Fig. 2 shows an embodiment of a system according to the invention with an electronic device according to the embodiment of fig. 1 in a partial view, wherein only the first housing part 10.1 of the housing 10 is shown in fig. 2. The first housing part 10.1 is produced as a metal diecast part made of aluminum and has four internal thread portions 10.1.1 for the fastening screws 12 shown in fig. 3 a. As can also be seen from fig. 3a, the circuit carrier 2 is screwed to the first housing part 10.1 of the housing 10 in the interior 10.2 of the housing 10 by means of the four fastening screws 12. For this purpose, the circuit carrier 2 has four through-openings 2.2, of which only two through-openings 2.2 are visible in fig. 1. On the one hand, the circuit carrier 2 and thus the electronic device is thereby fastened to the first housing part 10.1. On the other hand, threaded connections are also used for the following purposes: an electrically conductive connection, i.e. the grounding of the circuit carrier 2, is established. In fig. 3a, most of the electrical components of the circuit 4 are not shown.
Furthermore, it can be seen from the overview of fig. 2 and 3a that a shielding means 10.1.2 in the form of a shielding web is integrally formed on the first housing part 10.1 of the housing 10. The shielding webs 10.1.2 extend approximately parallel to the shielding walls 8.1 mounted on the circuit carrier 2 and serve to shield the edge strip 6 from components of the circuit 4 which are arranged on the mounting surface facing the first housing part 10.1 in fig. 3a and are therefore not visible. For this purpose, a shielding means 2.3, which corresponds to the shielding tab 10.1.2 and is designed as a shielding contact surface, is provided on the mounting surface, which is not visible in fig. 3 a; see fig. 7. In the assembled position of the system, i.e. when the electronic device is assembled in the closed housing 10, the shielding webs 10.1.2 of the first housing part 10.1 rest against the shielding contact surfaces 2.3 of the circuit carrier 2, so that the edge strip 6 effectively shields the electric and magnetic fields of the circuit 4 in this region on both sides of the circuit carrier 2 which are equipped with the electrical component 7.
Fig. 3b shows the detail denoted "a" in fig. 3a in an enlarged view. This detail is formed analogously to fig. 3b in the contact position between the shielding wall 8.1 and the first housing part 10.1, which is shown on the left in the drawing plane of fig. 3 a. In the enlarged illustration in fig. 3b, it can be seen that the shielding wall 8.1 mounted on the circuit carrier 2 engages in a groove formed by the edge 10.1.3 of the first housing part 10.1. In this way, the first housing part 10.1 overlaps the shielding wall 8.1 in a labyrinth-like manner, so that the shielding damping in the region of the edge strip 6 is further improved.
Fig. 4 shows a perspective view of a part of the system according to the invention of this embodiment. It is clearly apparent how the web 6.1 of the edge plug strip 6 in the assembled position of the system complements the web 10.1.4 of the first housing part 10.1, so that a circumferential tongue is obtained for the tongue-and-groove connection of the first housing part 10.1 to the second housing part 10.3, which is designed as a housing cover made of plastic. Fig. 7 shows the housing cover 10.3 and a groove 10.3.1 formed therein for the tongue-and-groove connection to the first housing part 10.1. In order to protect the electronic device according to the invention in the interior 10.2 of the housing 10 against water spray or the like, the tongue-and-groove connection 6.1, 10.1.4, 10.3.1 is additionally sealed by means of an adhesive not shown.
Fig. 5 shows a shielding section 8.2 of the shielding device 8, which is designed as a shielding cover made of steel sheet. As is evident from the overview of fig. 1 and 5, the shielding cover 8.2 is a separate component of the shielding device 8 from the shielding wall 8.1. When the electronic device according to the invention is mounted on the first housing part and therefore the system according to the invention is mounted, the shielding wall 8.1 and the shielding cover 8.2 of the shielding device 8 are mechanically connected to one another and to the circuit carrier 2 in such a way that the electric and magnetic fields of the circuit 4 are shielded from the edge strip 6 and thus from the environment. As also shown in fig. 5, the shielding cover 8.2 is chamfered (umkanten) several times, so that it has a closed edge 8.2.2 with the exception of the opening 8.2.1. The opening 8.2.1 is formed in a precisely fitting manner with the shielding wall 8.1, so that in the installation position of the electronic device shown in fig. 6, i.e. when the electronic device is mounted on the first housing part 10.1, the shielding device 8 is closed except for the side opposite to the mounting side 2.1 of the circuit carrier 2 shown in fig. 1. For this purpose, a web 8.2.3 is formed on the edge region of the opening 8.2.1 of the shielding cover 8.2, which web, when the shielding cover 8.2 is assembled, encompasses the edge of the shielding wall 8.1 which faces the shielding cover 8.2 in the assembled position of the system. Furthermore, the shielding cover 8.2 additionally has a projection 8.2.4 in the form of a spring web on the edge region of the opening 8.2.1, which projection brings the shielding cover 8.2 into close contact with the shielding wall 8.1. Accordingly, the shielding wall 8.1 and the shielding cover 8.2 overlap in order to ensure effective shielding attenuation of the shielding device 8 in the region of the edge strip 6.
As can be seen from fig. 6, the shielding device 8 with its shielding walls 8.1 and shielding cover 8.2 is arranged on the first housing part 10.1 of the housing 10 in the assembled position of the electronic device. In the illustrated installation position of the electronic device, the shielding device 8 covers a large part of the circuit carrier and thus also the through-opening 2.2, which is provided on the circuit carrier and is shown in fig. 1 for a fastening screw with which the circuit carrier is screwed to the first housing part 10.1 and is grounded on the latter. In the installed position of the electronic device, i.e. in the case of a mechanical connection of the shielding sections 8.1 and 8.2 of the shielding device 8 to one another, the threaded connection is not accessible.
However, the shielding device 8 can be removed again on account of the releasable connection between the shielding wall 8.1 and the shielding cover 8.2, so that the fastening screws are accessible even after the mechanical connection of the shielding sections 8.1 and 8.2. However, this applies in the present exemplary embodiment only to a limited extent, that is to say only up to the point in time at which the first housing part 10.1 is bonded to the housing cover 10.3 shown in fig. 7 and is therefore transferred into the installation position of the system shown in fig. 7. In a further possible embodiment, in which the second housing part is designed as a housing cover that can be released from the first housing part in the assembled position of the system, the aforementioned limitation is not present.
Fig. 7 shows a sectional view of the system according to the invention of the present embodiment in a complete view except for the shielding cover. The sectional view in the plane of the drawing in fig. 3a extends in the vertical direction in the region of the edge plug strip 6 and is shown in fig. 3a by a dashed sectional line 14. It is clearly apparent how the housing cover 10.3 closes the first housing part 10.1 in such a way that a closed housing 10 is obtained when the edge plug strip 6 is installed. The tongue and groove connection 10.1.4, 10.3.1 between the first housing part 10.1 and the housing cover 10.3 can also be seen.
The manner of handling the electronic device in its installation position and the system in its installation position is explained below with the aid of fig. 1 to 7.
With regard to the conversion of the electronic device of the exemplary embodiment into its assembly position, i.e. with regard to the assembly of the electronic device on the first housing part 10.1, the shielding wall 8.1 is first fastened to the circuit carrier 2 in the manner explained above; see fig. 1. After this, the complete electronic device, with the exception of the shielding cover 8.2, is now inserted into the first housing part 10.1 of the housing 10; see fig. 2-4. In this case, the shielding webs 10.1.2 of the first housing part 10.1 and the shielding contact surfaces 2.3 of the circuit carrier 2 shown in fig. 7 are brought into electrically conductive contact in the manner already explained, so that the edge connector strips 6 and thus the free environment in this region are shielded from the circuit 4 of the electronic device.
In order to complete the shielding device 8 of the electronic device, a shielding cover 8.2, which is shown separately in fig. 5, of the shielding device 8 is then fitted to the rest of the electronic device, in accordance with fig. 6, in particular to the already assembled shielding wall 8.1 of the shielding device 8. The shielding cover 8.2 surrounds the shielding wall 8.1 in the manner explained above. At the same time, the shielding cover 8.2 passes through an elongated hole, not shown here, provided in the circuit carrier 2 with a projection, not shown here, formed on the edge of the circuit carrier 2 opposite the mounting surface 2.1 visible in fig. 1. In this way, the shielding cover 8.2 is positioned and fixed in a desired manner relative to the shielding wall 8.1 and relative to the circuit carrier 2. The shielding device 8 is complete and protects the edge strip 6 in this region and thus protects the free environment against undesired electric and magnetic fields of the circuit 4. The shielding of the system is complete. In order to protect the electronic device installed in the first housing part 10.1 from undesired access, the housing 10 is adhesively bonded in the manner explained above by means of a housing cover 10.3 shown in fig. 7 and is thus non-releasably closed. The system according to the invention of this embodiment is in its installation position.
The present invention is not limited to the present embodiment. The electrical connection ends do not necessarily have to be edge strips or strips at all. For example, the electrical connection terminals can also be arranged in a central region of a circuit carrier of the electronic device and thus in the assembly position of the electronic device according to the invention in a central region of the first housing part. The shielding section of this embodiment, which is designed as a shielding cover, can also be designed without a frame. Accordingly, the frame is either formed as a separate shielding section or is arranged on a shielding section formed by the shielding wall according to this embodiment. The at least two separate shielding sections may have any shape, spatial orientation and arrangement suitable for the respective individual case.
The materials for the individual components of the electronic device according to the invention and the system according to the invention can likewise be freely selected within a wide range of suitability and in accordance with the respective use case. For example, instead of steel plates and aluminum die castings, other metals and manufacturing methods may be used. In principle, metal alloys and composite materials are also conceivable. It is decisive whether the function according to the invention of the respective component can be fulfilled by the selected material. Depending on the space supply and the weight and temperature requirements, materials with a greater or lesser shielding attenuation can be used for the shielding device and/or the first housing part, and materials with a lower or higher specific heat capacity can be used for the first housing part. Other connection techniques known to the person skilled in the art and suitable for connecting housing parts or shielding sections are also possible. For example, it is also conceivable for the at least two separate shielding sections to be connected to one another non-releasably after the first assembly of the electronic device and after the first assembly of the system. The first housing part and the shielding means of the circuit carrier can also have other known and suitable configurations. The second housing part can be designed differently from the embodiment of the system according to the invention as a housing cover which can be released from the first housing part in the assembly position of the system.
