Description

[0001] Title: Method for producing an electronic component

[0002] Description

[0003] The invention relates to a method for producing an electronic component, as well as to the electronic component. In particular, the invention relates to the overmolding of an electronic unit and an electromagnetic actuator of the electronic component with a first plastic and a second plastic to produce a media-tight casing.

[0004] Methods for manufacturing electronic components with a media-tight enclosure are known from the prior art. For example, WO 2019 / 162084 A1 discloses such a component in the form of a connector.

[0005] It is an object of the invention to provide a method for producing an electronic component that enables a media-tight enclosure with a lower manufacturing effort and a shorter manufacturing time.

[0006] The problem is solved by the features of the independent claims. The subclaims preferably contain further developments of the invention.

[0007] The object is achieved by a method for producing an electronic component which has at least one electromagnetic actuator and an electronics unit. The method likewise comprises a first overmolding of the electronics unit with a first plastic to produce a first casing for the electronics unit. The method further comprises a second overmolding of the first casing together with the electromagnetic actuator to produce a second casing for the electronics unit and the electromagnetic actuator. In this case, the first plastic is injection-molded at a lower temperature and / or a lower pressure than the second plastic. By using two different plastics in the first casing and the second casing, a plastic with ideal properties for its intended function can be selected for each casing.

[0008] The first overmolding is designed in such a way that the first casing encloses the electronics unit in such a way that the electronics unit is not touched by the second casing during the second overmolding. As a result, the temperature- and pressure-sensitive electronics unit is protected by the first casing from influences such as temperature and pressure during the second injection of the second plastic. This allows the second overmolding to work within a wider parameter range, especially with regard to the temperature and pressure parameters, during the injection of the second plastic than would be the case if the electronics unit were directly exposed to the second overmolding. Thus, the sensitivities of the electronics unit do not have to be taken into account when selecting the second plastic for the second overmolding.

[0009] The second overmolding is designed in such a way that the electromagnetic actuator and the electronics unit are enclosed in a media-tight manner by the first sheath. Since the second sheath with the second plastic ensures the media-tightness of the actuator and the electronics unit, the first plastic does not have to ensure media-tightness. This means that a plastic can be selected for the first sheath that places as little stress as possible on the electronics unit when the first sheath is injection-molded with the first plastic. By splitting the tasks, low temperature and pressure stress on the electronics unit during overmolding and ensuring media-tightness in a first overmolding with a first plastic and a second overmolding with a second plastic, a plastic suitable for its task can be selected for each overmolding.This reduces the number of overmoldings required to achieve media-tightness to two. A media-tight coating means that no media surrounding the coating, such as water or oil, can penetrate the coating.

[0010] In an advantageous embodiment, it is provided that at least two electrically conductive pin elements are connected to the electronics unit before the first overmolding, in particular by means of through-plating. The electronics unit is completely enclosed by the first sheathing during the first overmolding, with the electrically conductive pin elements protruding from the first sheathing. In an alternative advantageous embodiment, the electrically conductive pin elements are connected to the electronics unit after the first overmolding, in particular by means of through-plating, by the pin elements being pressed through the first sheathing. The electronics unit can be supplied with power and controlled by the pin elements protruding from the first sheathing. The pin elements are supported by the first sheathing and can dissipate greater forces into the first sheathing than if no first sheath were present.This allows the pin elements to also absorb forces during the second overmolding or during other stressful situations.

[0011] In a further advantageous embodiment, the electromagnetic actuator has at least one first recess, and the first casing is injection-molded in the first overmolding into such a shape that the first casing has at least one second protruding connecting element. The second protruding connecting element can be inserted into the first recess of the electromagnetic actuator. Alternatively or additionally, the electromagnetic actuator has at least one first protruding connecting element, and the first casing has at least one second recess into which the first connecting element of the electromagnetic actuator can be inserted. In the case of a connection between the first connecting element and the second recess and / or a connection between the first recess and the second connecting element, there is at least a partial positive connection.Form-fit locking is particularly important with respect to the radial direction of the actuator. This form-fit locking mechanism allows for a simple connection of the first casing to the actuator, preventing relative movement of the first casing relative to the actuator during the second injection. This reduces the number of elements required to support the first casing and the actuator, thus reducing manufacturing effort and time. Furthermore, manufacturing tolerances can be minimized.

[0012] In a further advantageous embodiment, the first sheath is injection-molded in the first overmolding in such a shape that the first sheath has at least a third recess. A positioning aid can be inserted into the third recess. Alternatively or additionally, it is provided that the first sheath has a third protruding connecting element. The third protruding connecting element can be inserted into the positioning aid. When the positioning aid and the third recess and / or the third connecting element are connected, there is at least a partial positive connection. Positive connection exists in particular with respect to a radial direction of the actuator. The positive connection between the positioning aid and the first sheath enables precise positioning of the first sheath. This ensures that the first sheath cannot move relative to the actuator during the second overmolding.In addition, manufacturing tolerances can be avoided.

[0013] In a particularly advantageous embodiment, the first sheath is connected to the electromagnetic actuator after the first overmolding by inserting the second connecting element into the first recess and / or by inserting the first connecting element into the second recess. Alternatively or additionally, the first sheath is connected to the positioning aid after the first overmolding by inserting the third connecting element into the positioning aid and / or by inserting the positioning aid into the third recess. After the first sheath has been connected to the positioning aid, the second overmolding is carried out. Due to the at least partially positive connection between the first sheath and the positioning aid, higher pressures can be used during the second overmolding when injecting the second plastic than if the first sheath were not supported.This allows for better filling of more complex geometries and reduces production time.

[0014] The invention also relates to an electronic component comprising an electromagnetic actuator, an electronic unit surrounded by a first casing made of a first injection-molded plastic, and a second casing made of a second injection-molded plastic. The second casing surrounds the first casing and the actuator. The first plastic is injection-moldable at a lower temperature and / or with a lower pressure than the second plastic. By using two different plastics in the first casing and the second casing, a plastic with ideal properties for its intended purpose can be selected for each casing.

[0015] The first sheath encloses the electronics unit in such a way that the second sheath does not directly touch the electronics unit. The first sheath protects the temperature- and pressure-sensitive electronics unit from influences such as temperature and pressure during the second injection of the second plastic. This allows the second overmolding to operate within a wider parameter range, especially with regard to the pressure and temperature parameters, during the injection of the second plastic than would be the case if the temperature- and pressure-sensitive electronics unit were directly exposed to the second overmolding. Thus, the sensitivities of the electronics unit do not need to be taken into account when selecting the second plastic for the second injection.

[0016] The second sheath encloses the electromagnetic actuator, while the electronics unit is sealed with the first sheath in a media-tight manner. Since the second sheath with the second plastic ensures media tightness of the actuator and the electronics unit, the first plastic does not need to ensure media tightness. This means that a plastic can be selected for the first sheath that places as little stress as possible on the electronics unit when the first sheath is injection molded with the first plastic. By splitting the tasks, low temperature and pressure stress on the electronics unit during overmolding, and ensuring media tightness in a first overmolding with a first plastic and a second overmolding with a second plastic, a suitable plastic can be selected for each overmolding. This reduces the number of overmoldings required to achieve media tightness to two overmoldings.A media-tight sheath means that no media surrounding the sheath, such as water or oil, penetrate the sheath.

[0017] In a preferred embodiment, two electrically conductive pin elements are connected to the electronics unit, with the electrically conductive pin elements protruding from the first sheath. The electronics unit can be supplied with power and / or output or receive control signals through the pin elements protruding from the first sheath. The pin elements are supported by the first sheath and can dissipate greater forces into the first sheath than if no first sheath were present. This allows the pin elements to also absorb the forces occurring during the second overmolding process or during other stressful situations.

[0018] The electromagnetic actuator advantageously has at least one first recess, and the first casing advantageously has at least one second protruding connecting element. Alternatively or additionally, the electromagnetic actuator has at least one first protruding connecting element, and the first casing has at least one second recess. The first connecting element can be connected to the second recess and / or the first recess can be connected to the second connecting element in such a way that at least a partial positive connection exists. Positive connection preferably exists with respect to a radial direction of the actuator. Due to the positive connection, a relative movement of the first casing with respect to the actuator during the second injection can be prevented by simply connecting the first casing to the actuator.This makes it possible to reduce the number of elements for supporting the first casing and the actuator, and thus the manufacturing effort and time. In addition, manufacturing tolerances can be minimized. The first casing advantageously has at least one third protruding connecting element which can be inserted into a positioning aid. Alternatively or additionally, the first casing has at least one third recess into which a positioning aid can be inserted, such that when the positioning aid and the third connecting element and / or the third recess are connected, at least a partial positive connection exists. Positive connection preferably exists with respect to a radial direction of the actuator. The positive connection between the positioning aid and the first casing enables precise positioning of the first casing.This ensures that the first jacket cannot move relative to the actuator during the second overmolding.

[0019] In another particularly advantageous embodiment, the electronics unit comprises a circuit board with a Hall sensor, wherein the Hall sensor is arranged closer to a surface of the first casing than the circuit board or another component on the circuit board. The Hall sensor can determine a field strength and thereby infer the presence of a magnet. Such a magnet can be located at one end of an actuating unit moving through a recess in the actuator. Thus, the position of the magnet and the actuating element can be determined by the Hall sensor. By positioning the Hall sensor closer to a surface behind which the magnet of the actuating unit is located than the circuit board or other elements of the circuit board, the position of the magnet behind the surface can be more accurately determined.

[0020] In a preferred embodiment, the first plastic has a lower thermal conductivity than the second plastic. During operation of the electromagnetic actuator, heat is generated in the actuator coils. This heat is dissipated into the immediate surroundings, including the second casing. By selecting a first plastic with a lower thermal conductivity than the second plastic, heat transfer of the coils' waste heat through the second casing to the surroundings of the electrical component is ensured, while at the same time, the first casing reduces heat transfer from the coil to the temperature-sensitive electronics unit.

[0021] In a particularly preferred embodiment, the first plastic is a thermoset and / or the second plastic is a thermoplastic. Thermosets are injection-moldable at low temperatures and low pressures and enable the electronics unit to be overmolded with the first thermoset casing at lower temperatures and pressures than would be the case with other plastics. Although thermoplastics are injected at higher pressures and temperatures than thermosets, they enable a media-tight seal between the actuator and the first casing with a single overmold. Since the temperature- and pressure-sensitive electronics unit is already protected by the first thermoset casing, the second overmold with a thermoplastic does not place an unreasonable strain on the electronics unit.This means that only two overmoldings are required to seal the actuator and the electronics unit in a media-tight manner, which reduces production time and effort.

[0022] Further details, advantages, and features of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawings. It shows:

[0023] Fig. 1 is a schematic view of an electronic component according to an embodiment of the invention,

[0024] Fig. 2 is a schematic view of the electronic unit of the electrical components according to the embodiment of the invention,

[0025] Fig. 3 is a schematic view of the electronic unit with the electronic component according to the embodiment of the invention with a first casing, and

[0026] Fig. 4 is a schematic view of the electronic component according to an embodiment of the invention with a positioning aid during production.

[0027] Figure 1 shows a schematic sectional view of an electrical component 1 according to an exemplary embodiment of the invention. The electrical component 1 comprises an electromagnetic actuator 2, an electronics unit 3, a first casing 4, and a second casing 5. The electronics unit 3 comprises a circuit board 13, to which one or more electrically conductive pin elements 6 are connected by means of through-hole plating, and a Hall sensor 14. The electronics unit 3 is completely enclosed by the first casing 4 and is not in direct contact with the second casing 5. The pin elements 6 protrude from the first casing 4.

[0028] The pin elements 6 can be connected to the circuit board 13 by means of through-plating prior to a first overmolding of the electronics unit 3 with a first plastic. Alternatively, the pin elements 6 can be inserted through the first casing 4 and the circuit board 13 after the first overmolding in order to be connected to the circuit board 13 by means of through-plating. In both ways of contacting the pin elements 6 with the circuit board 13, the pin elements 6 are supported by the first casing 4. As a result, the pin elements 6 can absorb greater forces than without support from the first casing 4. In particular, the pin elements 6 can withstand the pressure during a second overmolding of the first casing 4 with a second casing 5.

[0029] The first casing 4 is injection-molded from a first plastic, in particular a thermoset. Unlike other plastics, thermosets can be injected even at low pressures and temperatures and are therefore suitable for a first overmolding of the electronics unit 3. The second casing 5 is injection-molded from a second plastic, in particular a thermoplastic. Thermoplastics can only be injected at higher temperatures and pressures than thermosets and enable a media-tight sealing of the overmolded elements. Thus, in the exemplary embodiment shown in Fig. 1, the electronics unit 3 is completely enclosed by the first casing 4, and the first casing 4 and the actuator 2 are enclosed in a media-tight manner by the second casing 5.

[0030] Because the first plastic of the first casing 4 is already injection-moldable at a lower temperature and at a lower pressure, the first plastic can be injection-molded directly onto the electronics unit 3 without exposing the electronics unit 3 to undue stress. The first casing 4 now protects the electronics unit 3 from external influences. In particular, the first casing 4 protects the electronics unit 3 from unduly high temperatures and pressures during the second overmolding with the second plastic. By protecting the electronics unit 3 with the first casing 4, a plastic can be used for the second overmolding that only becomes injection-moldable at higher pressures and temperatures than the first plastic. As a result, the actuator 2 and the first casing 4 are subjected to greater stresses during the second overmolding than if the actuator 2 and the first casing were overmolding with a thermoset.However, a second overmolding of the actuator 2 and the first casing 4 with a thermoplastic is sufficient to create a media-tight seal between the actuator 2 and the first casing 4. The first plastic does not need to ensure a media-tight seal; this is already taken care of by the second plastic in the second overmolding. Therefore, a first plastic can be selected that does not subject the electronics unit 3 to excessive temperature and pressure stresses during the first overmolding. Because only two overmoldings are required to create a media-tight seal between the actuator 2 and the electronics unit 3, the manufacturing effort and time are reduced.

[0031] The actuator 2 has coils 22 that generate a magnetic field to displace an actuating unit 17 located within the actuator 2. When the magnetic field is generated, the coils 22 heat up and dissipate their heat into their surroundings. To reduce heat transfer from the coil 22 to the heat-sensitive electronic unit 3, while still ensuring effective heat transfer from the coil 22 to the surroundings of the electrical component 1, the first plastic preferably has a lower thermal conductivity than the second plastic.

[0032] The second casing 5 has at least one first recess 7 in which at least one second protruding connecting element 8 of the first casing 4 is located, and the first recess 7 and the second connecting element 8 are at least partially positively connected, in particular with respect to a radial direction of the actuator 2. The connection between the first recess 7 and the second connecting element 8 is so pronounced that movement of the first casing 4 relative to the second casing 5 is prevented during the second overmolding. The second connecting element 8 and the first recess 7 enable simple plugging together of the second casing 5 and the first casing 4, thereby eliminating the need for further auxiliary elements for fixing the first casing 4 along an axial direction 100 of the actuator 2 and the second casing 5. This reduces the manufacturing time and the manufacturing effort.

[0033] Likewise, the second casing 5 has a first, prominent connecting element 9, which is inserted into a second recess 10 of the first casing 4, and the first connecting element 9 and the second recess 10 are at least partially connected in a form-fitting manner. The connection between the second recess 10 and the first connecting element 9 is so pronounced that movement of the first casing 4 relative to the second casing 5 is prevented during the second overmolding, in particular with respect to the radial direction 200 and / or the axial direction 100. The first connecting element 9 and the second recess 10 enable simple plugging together of the second casing 5 and the first casing 4, in particular in the axial direction 100, and thus make it possible to dispense with further auxiliary elements for fixing the first casing 4 and the second casing 5. This reduces the manufacturing time and the manufacturing effort.The actuating unit 17, which can be moved by the actuator 2, has a magnet 18 at one end. The first casing 4 has a magnetic recess 16 into which the magnet 18 of the actuating unit 17 can be inserted. The magnetic recess 16 has a surface 15. The Hall sensor 14 is arranged closer to the surface 15 than the circuit board 13 or another component on the circuit board 13. This arrangement allows the field strength of the magnetic field to be measured more effectively, and thus the position of the magnet 18 and the actuating unit 17 to be determined, than if the circuit board 13 were still located between the Hall sensor 14 and the surface 15.

[0034] Figure 2 shows a schematic view of the electronics unit 3. The electronics unit 3 comprises at least one circuit board 13 and a Hall sensor 14. In the example shown, five electrically conductive pin elements 6 are electrically connected to the circuit board 13, in particular by means of through-hole plating. The pin elements 6 supply the circuit board 13 with power and / or serve to exchange data with the circuit board 13. The Hall sensor 14 is electrically connected to the circuit board 13 so that the measured values ​​of the Hall sensor 14 can be transmitted to the circuit board 13.

[0035] Figure 3 shows a schematic view of the electronics unit 3 with the first sheath 4. The contacting of the pin elements 6 with the circuit board 13 can, as shown in Figure 2, take place before a first overmolding of the electronics unit 3. Alternatively, the pin elements 6 can be inserted through the first sheath 4 and through the circuit board 13 after the first overmolding of the electronics unit 3. In both cases of connection of the pin elements 6 to the circuit board 13, before or after the first overmolding, the pin elements 6 are supported by the first sheath 4. As a result, the pin elements 6 can be subjected to greater forces than if the pin elements 6 were not supported by the sheath 4. In particular, the pin elements 6 can withstand pressure during the second overmolding.The first casing 4 completely encloses the electronic unit 3 so that direct contact between the electronic unit 3 and a second casing 5 is prevented.

[0036] The Hall sensor 14 is arranged on the circuit board 13; in particular, the Hall sensor 14 is electrically connected to the circuit board 13. The measured values ​​of the Hall sensor 14 can be transmitted to the circuit board 13 via this electrical connection. The first casing 4 has a magnetic recess 16 into which a magnet 18 on an actuating unit 17 can be inserted. The actuating unit 17 can be moved by the actuator 2. The movement of the actuating unit 17 moves the magnet 18 into or out of the magnetic recess 16. The magnetic recess 16 has a surface 15. The Hall sensor 14 is arranged closer to the surface 15 than the circuit board 13 or another component on the circuit board 13. This arrangement allows the field strength of the magnetic field to be measured more effectively, and thus the position of the magnet 18 and the actuator 17 to be determined, than if the circuit board 13 were still located between the Hall sensor 14 and the surface 15.

[0037] The first casing 4 has a third recess 11 for positioning and for fixing this position. The third recess 11 is arranged such that a positioning unit 12 can be inserted into the third recess 11, in particular in the axial direction 100, and at least a partial positive connection exists between the positioning unit 12 and the third recess 11.

[0038] Figure 4 shows a schematic view of the electronic component 1 according to the exemplary embodiment of the invention during production. In Figure 4, the magnetic recess 16 simultaneously fulfills the function of the third recess 11. Both recesses 11, 16 merge into one recess 11, 16. This is not necessarily the case; the third recess 11 could be provided at any location on the first casing 4.

[0039] After the first overmolding of the electronics unit 3, the electronics unit 3 is positioned with the first casing 4 on the actuator 2. The electronics unit 3 and the actuator 2 are to be aligned such that, after the second overmolding, the actuating unit 17 can be inserted into the actuator 2 and, at the same time, the magnet 18 of the actuating unit 17 can be inserted into the magnet recess 16. To ensure the precise alignment of the first casing 4 to the actuator 2, as shown in Fig. 4, the positioning aid 12 is inserted through the recess 19 of the actuator 2 into the third recess 11 of the first casing 4. The positioning aid 12 is at least partially positively connected to the actuator 2 and the third recess 11, in particular with respect to a radial direction 200.This fixes the actuator 2 and the first casing 4 in such a way that during the second overmolding of the actuator 2 and the first casing 4, no displacement occurs between the first casing 4 and the actuator 2 relative to one another. Once the second casing 5 has cooled or hardened after the second overmolding, the actuator 2 and the first casing 4 are connected to one another by the second casing such that the positioning aid 12 can be pulled out of the third recess 11 and the actuating unit recess 19 without the first casing 4 shifting relative to the actuator 2. After removing the positioning unit 12, the actuating unit 17 is inserted into the actuating unit recess 19 of the actuator 2, and the magnet 18 is inserted into the magnet recess 16 without resistance. The actuating unit can now be moved freely in the axial direction 100 by the actuator 2.

[0040] During the second overmolding, the actuator 2 and the first sheath 4 are enclosed in a media-tight manner. In this case, the pin elements 6 are not completely enclosed by the second sheath 5, so that the pin elements 6 can still be electrically contacted. The second sheath 5 preferably has a connector 20 around the pin elements 6, which enables a plug-in connection with a mating connector (not shown here). For example, an external unit (not shown) can be electrically contacted with the pin elements 6. The electronics unit 3 can be supplied with power from the external unit via the pin elements 6. Data can also be exchanged between the external unit and the electronics unit 3.

[0041] Furthermore, the second casing 5 has an access recess 21, which is arranged coaxially with the actuator recess 19 and is connected to the actuator recess 19. The access recess 21 of the second casing 5 allows the positioning aid 12 to be removed from the actuator recess 19 and the third recess 11. Likewise, the actuator 17 with the magnet 18 can be inserted into the actuator recess 19 and the magnet recess 16 through the access recess 21. Furthermore, the second casing 5 can have further functional features, for example, one or more internal threads for screw connections and surfaces for contacting surfaces of other surrounding elements can be provided.
