Abstract
Description

[0001] The present application relates to the field of electronic device modules, and particularly to an electronic device module, a controller including the electronic device module, and a vehicle including the controller. Background Art
[0002] The controller of a vehicle generally includes a DC support capacitor and a power module that are electrically connected to each other. In the prior art, the terminals of the DC support capacitor are usually electrically connected to the terminals of the power module through nuts.
[0003] However, limited by the protruding length of the terminals required for nut connection, the terminals with longer lengths increase the inductance loop between the DC support capacitor and the power module. At the same time, due to the poor reliability of nut connection, when the nut becomes loose, a gap will be generated between the two connected terminals, further increasing the stray inductance. And the higher stray inductance will cause large oscillations in the circuit system, resulting in problems such as energy attenuation and device damage. Summary of the Invention

[0059] Please refer to Figure 1 the structural schematic diagram of the vehicle 300 provided in an embodiment of the present application as shown.
[0060] As Figure 1As shown in the figure, the vehicle 300 of the present application includes a battery pack 301, a controller 200, and a motor 302. The controller 200 is electrically connected between the battery pack 301 and the motor 302 to control the output of the motor 302 by controlling the electrical energy entering the motor 302 from the battery pack 301.
[0061] The controller 200 of the present application includes a control module 201 and an electronic device module 100. The electronic device module 100 includes a first functional module 10 and a second functional module 20 that are electrically connected. The first functional module 10 is a DC support capacitor, and the second functional module 20 is a power module.
[0062] As Figure 1 shown in the figure, when the user inputs a driving signal to the control module 201, the driving signal can be transmitted to the battery pack 301, causing the battery pack 301 to output current to the first functional module 10. After being processed by the first functional module 10, the current is output to the second functional module 20. The second functional module 20, which is a power module, converts the direct current processed by the first functional module 10 into three-phase alternating current and transmits it to the motor 302. The motor 302 rotates under the action of the three-phase alternating current and transmits signals such as its own speed and torque to the control module 201, which are processed by the control module 201 and then fed back to the user.
[0063] Among them, the first functional module 10, which is a DC support capacitor, protects the electronic device module 100 of the present application by absorbing ripples, preventing the electronic device module 100 of the present application from being broken down due to high voltage.
[0064] For ease of description, the first functional module 10 of the electronic device module 100 of the present application is a DC support capacitor, and the second functional module 20 is a power module. It can be understood that in another embodiment, the first functional module 10 can be a power module, and the second functional module 20 can be a DC support capacitor. In some other embodiments, the first functional module and the second functional module can also be other functional devices. The present application does not make any special restrictions on this.
[0065] Please refer to Figure 2 the schematic structural diagram of the electronic device module 100 provided in an embodiment of the present application shown in the figure, and please refer to Figure 3 the schematic structural diagram of the first functional module 10 of the electronic device module 100 provided in an embodiment of the present application shown in the figure, and please also refer to Figure 4 the schematic structural diagram of the second functional module 20 of the electronic device module 100 provided in an embodiment of the present application shown in the figure.
[0066] As Figures 2 - 4As shown in the figure, the electronic device module 100 of the present application includes a first functional module 10 and a second functional module 20. Among them, the first functional module 10 and the second functional module 20 are arranged at intervals. On the surface of the first functional module 10 facing the second functional module 20, a first terminal 31 and a second terminal 32 protrude, and both the first terminal 31 and the second terminal 32 extend towards the second functional module 20. On the surface of the second functional module 20 facing the first functional module 10, a first terminal 31 and a second terminal 32 also protrude, and both the first terminal 31 and the second terminal 32 extend towards the first functional module 10.
[0067] As Figure 3 shown, the first functional module 10 includes a first body portion 11. The first terminal 31 provided on the first functional module 10 is a first capacitor terminal 31a, and the second terminal 32 provided on the first functional module is a second capacitor terminal 32a. Both the first capacitor terminal 31a and the second capacitor terminal 32a are electrically connected to the internal structure of the first body portion 11.
[0068] Among them, both the first capacitor terminal 31a and the second capacitor terminal 32a are sheet-shaped, and along the thickness direction of the first capacitor terminal 31a, the projection of the second capacitor terminal 32a on the first capacitor terminal 31a is at least partially received within the first capacitor terminal 31a.
[0069] As Figure 4 shown, the second functional module 20 includes a second body portion 21. The first terminal 31 provided on the second functional module 20 is a first power terminal 31b, and the second terminal 32 provided on the second functional module 20 is a second power terminal 32b. Both the first power terminal 31b and the second power terminal 32b are electrically connected to the internal structure of the second body portion 21.
[0070] Among them, both the first power terminal 31b and the second power terminal 32b are sheet-shaped, and along the thickness direction of the first power terminal 31b, the projection of the second power terminal 32b on the first power terminal 31b is at least partially received within the first power terminal 31b.
[0071] Both the first terminal 31 and the second terminal 32 are sheet-shaped. Among them, for the convenience of description, Figure 2 in the following figures, the extending direction of the first terminal 31 and the second terminal 32 is set as the first direction 001, the thickness direction of the first terminal 31 and the second terminal 32 is set as the second direction 002, and the width direction of the first terminal 31 and the second terminal 32 is set as the third direction 003.
[0072] Please refer to Figure 5 the front view structural schematic diagram of the electronic device module 100 provided in an embodiment of the present application shown in the figure, and please refer to Figure 6An enlarged schematic view of the electronic device module 100 provided in an embodiment of the present application is shown. Please also refer to Figure 4 .
[0073] As Figures 4 - 6 shown, along the first direction 001, the first capacitor terminal 31a and the first power terminal 31b are located between the first body portion 11 and the second body portion 21, and the sum of the lengths of the first capacitor terminal 31a and the first power terminal 31b is greater than the maximum spacing distance between the first body portion 11 and the second body portion 21. So that the end of the first capacitor terminal 31a can overlap on the end of the first power terminal 31b, thereby realizing the conduction between the first capacitor terminal 31a and the second capacitor terminal 32a.
[0074] As Figures 4 - 6 shown, along the first direction 001, the second capacitor terminal 32a and the second power terminal 32b are also located between the first body portion 11 and the second body portion 21, wherein the sum of the lengths of the second capacitor terminal 32a and the second power terminal 32b is less than the spacing distance between the first body portion 11 and the second body portion 21.
[0075] The electronic device module 100 of the present application further includes a connecting member 40, and the connecting member 40 is bridged between the second capacitor terminal 32a and the second power terminal 32b. So that the second capacitor terminal 32a and the second power terminal 32b can be conducted through the connecting member 40.
[0076] Among them, the first capacitor terminal 31a can be used as the positive output terminal of the DC support capacitor, and the second capacitor terminal 32a can be used as the negative output terminal of the DC support capacitor. Correspondingly, the first power terminal 31b can be used as the positive input terminal of the power module, and the second power terminal 32b can be used as the negative input terminal of the power module.
[0077] That is to say, in the electronic device module 100 of the present application, the current flow direction between the first capacitor terminal 31a and the first power terminal 31b is from the first capacitor terminal 31a to the first power terminal 31b. And the current flow direction between the second capacitor terminal 32a and the second power terminal 32b is from the second power terminal 32b through the connecting member 40 to the first power terminal 31b.
[0078] Based on the fact that the current flow direction in the wire is related to the magnetic field direction generated by the wire, and the generation of stray inductance is also related to the change of the magnetic field. It can be understood that the two first terminals 31 are conducted to each other, and the two second terminals 32 are conducted to each other. So that the magnetic fields generated by the currents flowing in the two first terminals 31 can cancel out the magnetic fields generated by the currents flowing to the two second terminals 32 and the connecting member 40, thereby reducing the generation of stray inductance.
[0079] Meanwhile, since both the first terminal 31 and the second terminal 32 are sheet-shaped, the magnetic fields generated by the currents in the first terminal 31 and the second terminal 32 will also extend along the third direction 003. It can be understood that the projection of the second capacitor terminal 32a on the first capacitor terminal 31a is at least partially received within the first capacitor terminal 31a, and the projection of the second power terminal 32b on the first power terminal 31b is also at least partially received within the first power terminal 31b. This can increase the area of the overlapping region between the first terminal 31 and the second terminal 32, reduce the distance between the first terminal 31 and the second terminal 32, and thus reduce the equivalent inductance loop formed between the first terminal 31 and the second terminal 32.
[0080] Since the longer the inductance loop, the higher the corresponding stray inductance generated. The existence of stray inductance will cause problems such as power loss or signal attenuation in the circuit system. In the power module, stray inductance will increase the voltage fluctuation range, thus causing damage to the power module. When the electronic device module 100 is in a high-frequency situation, stray inductance will also cause an increase in the switching loss of the power module.
[0081] Therefore, by electrically connecting the first terminals 31 and the second terminals 32 of the first functional module 10 and the second functional module 20 in the electronic device module 100 of the present application, and making the projection of each second terminal 32 on the first terminal 31 be at least partially received within the first terminal 31, it is also possible to reduce the generation of stray inductance while increasing the service life of the electronic device module 100 of the present application.
[0082] In another embodiment, the first capacitor terminal 31a can be used as the negative output terminal of the DC support capacitor, and the second capacitor terminal 32a can be used as the positive output terminal of the DC support capacitor. Correspondingly, the first power terminal 31b can be used as the negative input terminal of the power module, and the second power terminal 32b can be used as the positive input terminal of the power module.
[0083] At this time, the current flow direction between the first capacitor terminal 31a and the first power terminal 31b is still opposite to the current flow direction between the second capacitor terminal 32a and the second power terminal 32b. The magnetic fields generated by the currents in the two first terminals 31 can still cancel out the magnetic fields generated by the currents in the two second terminals 32. It still has the effect of reducing the generation of stray inductance.
[0084] It can be understood that in some other embodiments, other structures can also be used to achieve electrical connection between the second capacitor terminal 32a and the second power terminal 32b. The present application does not make any special restrictions on this.
[0085] Please refer to Figure 7 Another enlarged schematic diagram of the electronic device module 100 provided in an embodiment of the present application as shown.
[0086] As shown Figure 7 in the figure, along the first direction 001, the sum of the lengths of the first capacitor terminal 31a and the first power terminal 31b is equal to the maximum spacing distance between the first body portion 11 and the second body portion 21. Correspondingly, the ends of the first capacitor terminal 31a and the first power terminal 31b can be docked with each other to achieve conduction therebetween.
[0087] Please refer to Figure 8 the further enlarged schematic diagram of the electronic device module 100 provided in an embodiment of the present application as shown.
[0088] As shown Figure 8 in the figure, along the first direction 001, the sum of the lengths of the first capacitor terminal 31a and the first power terminal 31b is less than the maximum spacing distance between the first body portion 11 and the second body portion 21.
[0089] The sum of the lengths of the first capacitor terminal 31a and the first power terminal 31b is L1, the maximum spacing distance between the first body portion 11 and the second body portion 21 is D1, and the thickness of the first terminal 31 is H1. Among them, D1 - L1 ≤ H1 / 2. Correspondingly, the ends of the first capacitor terminal 31a and the first power terminal 31b are conducted in a molten filling manner.
[0090] It can be understood that setting D1 - L1 ≤ H1 / 2 avoids the situation that it is difficult to conduct between the first capacitor terminal 31a and the first power terminal 31b due to the too large spacing between the first capacitor terminal 31a and the first power terminal 31b, and ensures the electrical connection between the two first terminals 31.
[0091] Among them, in the embodiments of the present application and subsequent embodiments, the lap conduction means that two structures are arranged staggeredly in space, and one of the structures is placed on the surface of the other structure, so that there is an overlapping area between the two structures, and then an electrical connection means acts on the overlapping area of the two structures to connect the two structures into one body.
[0092] Exemplarily, the lap conduction between the first capacitor terminal 31a and the first power terminal 31b means that along the first direction 001, the first capacitor terminal 31a and the first power terminal 31b are arranged in a staggered manner, and the surface of the first capacitor terminal 31a facing the first power terminal 31b is in contact with the surface of the first power terminal 31b facing the first capacitor terminal 31a, so that there is an overlapping area between the first capacitor terminal 31a and the first power terminal 31b in the first direction 001. Then, the overlapping area of the first capacitor terminal 31a and the first power terminal 31b is connected into one body to achieve the lap conduction between the first capacitor terminal 31a and the first power terminal 31b.
[0093] In the embodiments of the present application and subsequent embodiments, butt conduction means that two structures extend towards each other respectively, and the end faces of each structure close to the other structure are in contact with each other, and then the two structures are connected into one body by means of electrical connection.
[0094] Exemplarily, the butt conduction between the first capacitor terminal 31a and the first power terminal 31b means that the end face of the first capacitor terminal 31a facing the second body portion 21 is in contact with the end face of the first power terminal 31b facing the first body portion 11, and the end faces of the first capacitor terminal 31a and the first power terminal 31b in contact with each other are connected into one body, so as to realize the butt conduction between the first capacitor terminal 31a and the first power terminal 31b.
[0095] In the embodiments of the present application and subsequent embodiments, melt filling conduction means that two structures extend towards each other respectively, and the end faces of each structure close to the other structure are spaced apart from each other, and then a molten material is filled in the gap between the two end faces, and the molten material is melted by corresponding electrical connection means, so as to connect the two structures into one body.
[0096] Exemplarily, the melt filling conduction between the first capacitor terminal 31a and the first power terminal 31b means that the end face of the first capacitor terminal 31a facing the second body portion 21 is spaced apart from the end face of the first power terminal 31b facing the first body portion 11. Along the first direction 001, a molten material (not shown in the figure) is filled between the first capacitor terminal 31a and the first power terminal 31b, and the molten material is melted by high temperature, so as to connect the molten material with the first capacitor terminal 31a and the first power terminal 31b respectively, and ensure that the molten material fills the gap between the first capacitor terminal 31a and the first power terminal 31b, so that the first capacitor terminal 31a and the first power terminal 31b can be conducted under the action of the molten material. The melt filling conduction between the first capacitor terminal 31a and the first power terminal 31b is realized.
[0097] In one embodiment, the first capacitor terminal 31a and the first power terminal 31b are connected by a non-contact energy source scanning connection technology. Among them, as Figures 4 - 6 shown, the length of the first capacitor terminal 31a is greater than the length of the second capacitor terminal 32a, and the length of the first power terminal 31b is also greater than the length of the second power terminal 32b. That is to say, a part of the first capacitor terminal 31a is exposed outside the second capacitor terminal 32a, and a part of the first power terminal 31b is also exposed outside the second power terminal 32b.
[0098] As Figures 4 - 6As shown, along the first direction 001, the overlapping portion of the first capacitor terminal 31a and the first power terminal 31b is located between the second capacitor terminal 32a and the second power terminal 32b, so that an external energy source can scan the overlapping portion of the first capacitor terminal 31a and the first power terminal 31b, and the overlapping portions of the first capacitor terminal 31a and the first power terminal 31b are fused together to achieve conduction between the first capacitor terminal 31a and the first power terminal 31b.
[0099] It can be understood that the connection method between the two first terminals 31 in the electronic device module 100 of the present application adopts a non-contact energy source scanning connection technology, which can avoid the influence of the vibration of the external structure itself on the connection effect during the connection process. Thus, the connection stability between the two first terminals 31 of the electronic device module 100 of the present application is ensured.
[0100] In some other embodiments, the connection method between the two first terminals 31 in the electronic device module 100 of the present application can also be other methods, and the present application does not make special limitations on this.
[0101] Please refer to Figure 9 the schematic structural diagram of the connector 40 provided in an embodiment of the present application as shown. And cooperate with referring to Figure 2 and Figure 6 .
[0102] As Figure 2 , Figure 6 and Figure 9 shown, the connector 40 includes a connecting portion 43 and two docking portions. The two docking portions are the first docking portion 41 and the second docking portion 42 respectively. Along the first direction 001, the first docking portion 41 and the second docking portion 42 are located on opposite sides of the connecting portion 43, and the sum of the lengths of the first docking portion 41, the second docking portion 42 and the connecting portion 43 is greater than the maximum spacing distance between the second capacitor terminal 32a and the second power terminal 32b.
[0103] Among them, the first docking portion 41 overlaps on the surface of the second capacitor terminal 32a and conducts with the second capacitor terminal 32a, and the second docking portion 42 overlaps on the surface of the second power terminal 32b and conducts with the second power terminal 32b. To achieve conduction between the second capacitor terminal 32a and the second power terminal 32b that are spaced apart from each other.
[0104] In one embodiment, as Figures 4 - 6As shown, the opposite ends of the connecting member 40 are also connected by a connection technique of non-contact energy source scanning. It can be understood that the lengths of the second capacitor terminal 32a and the second power terminal 32b extending out of the corresponding first body portion 11 and second body portion 21 are such that it is convenient for an external energy source to scan the overlapping portions of the connecting member 40 with the second capacitor terminal 32a and the second power terminal 32b, thereby achieving the conduction of the connecting member 40 to the second capacitor terminal 32a and the second power terminal 32b.
[0105] It can be understood that the connection method between the two second terminals 32 in the electronic device module 100 of the present application adopts a connection technique of non-contact energy source scanning, which can avoid the influence of the vibration of the external structure itself on the connection effect during the connection process. Thus, the connection stability between each second terminal 32 and the connecting member 40 in the electronic device module 100 of the present application is ensured.
[0106] In some other embodiments, the connection method between each second terminal 32 and the connecting member 40 in the electronic device module 100 of the present application can also be other methods, and the present application does not make special limitations on this.
[0107] Please refer to Figure 10 the partial enlarged schematic diagram of the electronic device module 100 provided in an embodiment of the present application as shown. Among them, in order to facilitate the description of the connection relationship between the second docking portion 42 and the second power terminal 32b, Figure 10 some structures are omitted.
[0108] As Figure 10 shown, the sum of the lengths of the first docking portion 41, the second docking portion 42, and the connecting portion 43 is equal to the maximum spacing distance between the second capacitor terminal 32a and the second power terminal 32b.
[0109] Among them, the end of the first docking portion 41 is in butt conduction with the end of the second capacitor terminal 32a, and the end of the second docking portion 42 is in butt conduction with the end of the second power terminal 32b. To achieve the conduction of the mutually spaced second capacitor terminal 32a and second power terminal 32b.
[0110] Please refer to Figure 11 another partial enlarged schematic diagram of the electronic device module 100 provided in an embodiment of the present application as shown. Among them, in order to facilitate the description of the connection relationship between the second docking portion 42 and the second power terminal 32b, Figure 11 some structures are omitted.
[0111] As Figure 11 shown, the sum of the lengths of the first docking portion 41, the second docking portion 42, and the connecting portion 43 is less than the maximum spacing distance between the second capacitor terminal 32a and the second power terminal 32b.
[0112] The sum of the lengths of the first docking portion 41, the second docking portion 42, and the connecting portion 43 is L2, the maximum spacing distance between the second capacitor terminal 32a and the second power terminal 32b is D2, and the thickness of the second terminal 32 is H2. Among them, D2 - L2 < H2 / 2. Correspondingly, the ends of the second capacitor terminal 32a and the second power terminal 32b are electrically connected by means of molten filling.
[0113] It can be understood that setting D2 - L2 ≤ H2 / 2 avoids the situation where it is difficult to conduct electricity between the second capacitor terminal 32a and the second power terminal 32b due to the too large spacing between them, ensuring the electrical connection between the two second terminals 32.
[0114] In one embodiment, as Figure 2 、 Figure 6 and Figure 9 shown, there are multiple first docking portions 41, and along the third direction 003, the respective first docking portions 41 are spaced apart from each other and are sequentially connected to the connecting portion 43.
[0115] Since an external force needs to be applied to the first docking portion 41 when connecting the first docking portion 41 and the second capacitor terminal 32a, and the first docking portion 41 is deformed to reduce the spacing between the first docking portion 41 and the second capacitor terminal 32a in the second direction 002. It can be understood that setting multiple first docking portions 41 can reduce the stress concentration compared with one first docking portion 41, thereby reducing the difficulty of deforming each first docking portion 41. It is beneficial to realize the conduction between the first docking portion 41 and the second capacitor terminal 32a. Furthermore, the connection stability of the electronic device module 100 of the present application is improved.
[0116] At the same time, there are multiple second docking portions 42, and along the third direction 003, the respective second docking portions 42 are spaced apart from each other and are sequentially connected to the connecting portion 43.
[0117] Since an external force needs to be applied to the second docking portion 42 when connecting the second docking portion 42 and the second power terminal 32b, and the second docking portion 42 is deformed to reduce the spacing between the second docking portion 42 and the second power terminal 32b in the second direction 002. It can be understood that setting multiple second docking portions 42 can reduce the stress concentration compared with one second docking portion 42, thereby reducing the difficulty of deforming each second docking portion 42. It is beneficial to realize the conduction between the second docking portion 42 and the second power terminal 32b. Furthermore, the connection stability of the electronic device module 100 of the present application is improved.
[0118] In one embodiment, the number of the first docking portions 41 is the same as that of the second docking portions 42, so as to facilitate the manufacture of the connecting member 40. It can be understood that in other embodiments, the number of the first docking portions 41 and the number of the second docking portions 42 may be different. The present application does not make special limitations on this.
[0119] In one embodiment, please refer back to Figure 3 、 Figure 4 and Figure 6 . The first terminals 31 of the two functional modules include a plurality of first sub-terminals 311. Specifically, in the first functional module 10, the first capacitor terminal 31a includes a plurality of first capacitor sub-terminals 311a, and along the third direction 003, the respective first capacitor sub-terminals 311a are spaced apart. In the second functional module 20, the first power terminal 31b includes a plurality of first power sub-terminals 311b, and along the third direction 003, the respective first power sub-terminals 311b are spaced apart.
[0120] Based on the mutual overlap of the first power terminal 31b and the first capacitor terminal 31a, and when connecting the first capacitor terminal 31a and the first power terminal 31b, an external force also needs to be applied to the first power terminal 31b and the first capacitor terminal 31a to cause deformation, so as to reduce the distance between the first power terminal 31b and the first capacitor terminal 31a.
[0121] It can be understood that setting a plurality of first power sub-terminals 311b and a plurality of first capacitor sub-terminals 311a can reduce the stress concentration between the first power terminal 31b and the first capacitor terminal 31a, thereby reducing the deformation difficulty of each first power sub-terminal 311b and first capacitor sub-terminal 311a. It is beneficial to realize the conduction between the first power sub-terminals 311b and the first capacitor sub-terminals 311a. Furthermore, the connection stability of the electronic device module 100 of the present application is improved.
[0122] In one embodiment, along the second direction 002, in the overlapping area of the first capacitor terminal 31a and the first power terminal 31b, the gap between the first capacitor terminal 31a and the first power terminal 31b is less than or equal to 0.2 mm. To ensure that during the process of the energy source scanning the overlapping area, the molten first capacitor terminal 31a and first power terminal 31b can completely fill this gap, so as to ensure the sufficient connection between the first capacitor terminal 31a and the first power terminal 31b, and avoid phenomena such as explosion holes and false soldering. Furthermore, the connection stability of the electronic device module 100 of the present application is guaranteed.
[0123] In one embodiment, along the second direction 002, in the overlapping region between the first docking portion 41 and the second capacitor terminal 32a, the gap between the first docking portion 41 and the second capacitor terminal 32a is less than or equal to 0.2 mm. In the overlapping region between the second docking portion 42 and the second power terminal 32b, the gap between the second docking portion 42 and the second power terminal 32b is less than or equal to 0.2 mm. This ensures sufficient connection between the first docking portion 41 and the second capacitor terminal 32a, and between the second docking portion 42 and the second power terminal 32b. Thus, the connection stability of the electronic device module 100 of the present application is ensured.
[0124] In one embodiment, as Figure 3 , Figure 4 and Figure 6 shown, the number of the first power sub-terminals 311b is the same as the number of the first capacitor sub-terminals 311a, and each first capacitor sub-terminal 311a is overlapped and electrically connected to a first power sub-terminal 311b.
[0125] It can be understood that in other embodiments, since the first capacitor terminal 31a is overlapped on the first power terminal 31b, the number of the first capacitor sub-terminals 311a can be greater than the number of the first power sub-terminals 311b, and there is a case where multiple first capacitor sub-terminals 311a are overlapped on one first power sub-terminal 311b. In other embodiments, the numbers of the first capacitor sub-terminals 311a and the first power sub-terminals 311b can also be other values.
[0126] In one embodiment, for the first functional module 10, along the third direction 003, the ratio of the width of the first capacitor terminal 31a to the width of the second capacitor terminal 32a is between 0.8 and 1.2. When the ratio of the width of the first capacitor terminal 31a to the width of the second capacitor terminal 32a is less than 0.8, the projection of the second capacitor terminal 32a on the first capacitor terminal 31a does not increase the area of the first capacitor terminal 31a, so that a part of the magnetic field generated by the first capacitor terminal 31a cannot be cancelled by the magnetic field generated by the second capacitor terminal 32a, and the magnetic field generated by the second capacitor terminal 32a cannot be cancelled relative to the magnetic field generated by the first capacitor terminal 31a. Thus, stray inductance is generated.
[0127] When the ratio of the width of the first capacitor terminal 31a to the width of the second capacitor terminal 32a is greater than 1.2, the projection of the first capacitor terminal 31a on the second capacitor terminal 32a does not increase the area of the second capacitor terminal 32a, so that a part of the magnetic field generated by the second capacitor terminal 32a cannot be effectively cancelled relative to the magnetic field generated by the first capacitor terminal 31a, and the magnetic field generated by the first capacitor terminal 31a cannot be cancelled relative to the magnetic field generated by the second capacitor terminal 32a. Thus, stray inductance is generated.
[0128] That is, by setting the ratio of the width of the first capacitor terminal 31a to the width of the second capacitor terminal 32a to be between 0.8 and 1.2, the cancellation ratio of the magnetic field generated by the current in the first capacitor terminal 31a and the magnetic field generated by the current in the second capacitor terminal 32a can be increased, thereby further ensuring the effect of reducing the stray inductance of the electronic device module 100 of the present application.
[0129] In one embodiment, the ratio of the width of the first capacitor terminal 31a to the width of the second capacitor terminal 32a is 1, and the first capacitor terminal 31a and the second capacitor terminal 32a are arranged in alignment.
[0130] In one embodiment, for the second functional module 20, along the third direction 003, the ratio of the width of the first power terminal 31b to the width of the second power terminal 32b is between 0.8 and 1.2. When the ratio of the width of the first power terminal 31b to the width of the second power terminal 32b is less than 0.8, the projection of the second power terminal 32b on the first power terminal 31b does not increase in the area of the first power terminal 31b, so that a part of the magnetic field generated by the first power terminal 31b cannot be cancelled by the magnetic field generated by the second power terminal 32b, and the magnetic field generated by the second power terminal 32b cannot be cancelled relative to the magnetic field generated by the first power terminal 31b. As a result, stray inductance is generated.
[0131] When the ratio of the width of the first power terminal 31b to the width of the second power terminal 32b is greater than 1.2, the projection of the first power terminal 31b on the second power terminal 32b does not increase in the area of the second power terminal 32b, so that a part of the magnetic field generated by the second power terminal 32b cannot be cancelled by the magnetic field generated by the first power terminal 31b, and the magnetic field generated by the first power terminal 31b cannot be cancelled relative to the magnetic field generated by the second power terminal 32b. As a result, stray inductance is generated.
[0132] That is, by setting the ratio of the width of the first power terminal 31b to the width of the second power terminal 32b to be between 0.8 and 1.2, the cancellation ratio of the magnetic field generated by the current in the first power terminal 31b and the magnetic field generated by the current in the second power terminal 32b can be increased, thereby further ensuring the effect of reducing the stray inductance of the electronic device module 100 of the present application.
[0133] In one embodiment, the ratio of the width of the first power terminal 31b to the width of the second power terminal 32b is 1, and the first power terminal 31b and the second power terminal 32b are aligned with each other.
[0134] In one embodiment, the electronic device module 100 of the present application further includes five insulators 50, where there are two insulators 50, namely a capacitor insulator 50a and a power insulator 50b respectively.
[0135] Specifically, please refer to Figure 12 the enlarged schematic diagram of the first functional module 10 of the electronic device module 100 provided in one embodiment of the present application as shown. And cooperate with referring to Figure 3 .
[0136] As Figure 3 and Figure 12 shown, the capacitor insulator 50a is fixed between the first capacitor terminal 31a and the second capacitor terminal 32a, and is in contact with the first capacitor terminal 31a and the second capacitor terminal 32a. Along the first direction 001, the extension length of the capacitor insulator 50a is between the first capacitor terminal 31a and the second capacitor terminal 32a.
[0137] It can be understood that the setting of the capacitor insulator 50a can prevent voltage breakdown of the gap between the first capacitor terminal 31a and the second capacitor terminal 32a, and prevent short circuit caused by the too close distance between the first capacitor terminal 31a and the second capacitor terminal 32a in the second direction 002, thereby protecting the use safety of the electronic device module 100 of the present application.
[0138] At the same time, the setting of the capacitor insulator 50a can also reduce the distance between the first capacitor terminal 31a and the second capacitor terminal 32a on the premise of ensuring the safety distance between the first capacitor terminal 31a and the second capacitor terminal 32a in the second direction 002, thereby reducing the inductance loop of the electronic device module 100 of the present application, and further reducing the stray inductance of the electronic device module 100 of the present application.
[0139] In one embodiment, as Figure 3 and Figure 12 shown, the capacitor insulator 50a includes a first insulating portion 51a and a first insulating protrusion 52a. Wherein, the first insulating portion 51a is arranged between the first capacitor terminal 31a and the second capacitor terminal 32a, and the end of the first insulating portion 51a is provided with a first insulating protrusion 52a, and the first insulating protrusion 52a exposes on the surface of the second capacitor terminal 32a and extends along the second direction 002 in a direction away from the first capacitor terminal 31a. In the second direction 002, the first insulating protrusion 52a is spaced from the connecting member 40.
[0140] It can be understood that the provision of the first insulating protrusion 52a increases the creepage distance between the end of the second capacitor terminal 32a and the first capacitor terminal 31a, preventing the current at the end of the second capacitor terminal 32a from directly extending along the surface of the capacitor insulating member 50a and connecting with the current of the first capacitor terminal 31a. Thus, while reducing the spacing between the first capacitor terminal 31a and the second capacitor terminal 32a in the second direction 002, the creepage distance between the first capacitor terminal 31a and the second capacitor terminal 32a is increased, further ensuring the safe use of the electronic device module 100 of the present application and further reducing the generation of stray inductance.
[0141] In one embodiment, as Figure 3 and Figure 12 shown, a first groove 521a is provided on the surface of the first insulating protrusion 52a away from the first capacitor terminal 31a, and a first groove 521a is also provided on the surface of the first insulating protrusion 52a away from the second capacitor terminal 32a. It can be understood that the provision of the first groove 521a further increases the creepage distance between the first capacitor terminal 31a and the second capacitor terminal 32a, further ensuring the safe use of the electronic device module 100 of the present application and further reducing the generation of stray inductance.
[0142] In one embodiment, the number of the first grooves 521a can be multiple. In another embodiment, the first groove 521a can also be provided only on the surface of the first insulating protrusion 52a away from the first capacitor terminal 31a or on the surface of the first insulating protrusion 52a away from the second capacitor terminal 32a. The present application does not make special restrictions on this.
[0143] Please refer to Figure 13 the enlarged schematic diagram of the second functional module 20 of the electronic device module 100 provided in one embodiment of the present application shown. And cooperate with referring to Figure 4 .
[0144] As Figure 4 and Figure 13 shown, the power insulating member 50b is fixed between the first power terminal 31b and the second power terminal 32b and is in contact with the first power terminal 31b and the second power terminal 32b. Along the first direction 001, the extension length of the power insulating member 50b is between the first power terminal 31b and the second power terminal 32b.
[0145] It can be understood that the provision of the power insulating member 50b can prevent voltage breakdown of the gap between the first power terminal 31b and the second power terminal 32b and prevent short circuits caused by the too-close distance between the first power terminal 31b and the second power terminal 32b in the second direction 002, thus protecting the safe use of the electronic device module 100 of the present application.
[0146] Meanwhile, the provision of the power insulating member 50b can also reduce the spacing between the first power terminal 31b and the second power terminal 32b on the premise of ensuring the safety distance between the first power terminal 31b and the second power terminal 32b in the second direction 002, thereby reducing the inductance loop of the electronic device module 100 of the present application, and further reducing the stray inductance of the electronic device module 100 of the present application.
[0147] In one embodiment, as Figure 4 and Figure 13 shown, the power insulating member 50b includes a second insulating portion 51b and a second insulating protrusion 52b. Among them, the second insulating portion 51b is disposed between the first power terminal 31b and the second power terminal 32b. The end of the second insulating portion 51b is provided with a second insulating protrusion 52b. The second insulating protrusion 52b exposes on the surface of the second power terminal 32b and extends in the second direction 002 away from the first power terminal 31b. In the second direction 002, the second insulating protrusion 52b is spaced apart from the connecting member 40.
[0148] It can be understood that the provision of the second insulating protrusion 52b increases the creepage distance between the end of the second power terminal 32b and the first power terminal 31b to prevent the current at the end of the second power terminal 32b from directly extending along the surface of the power insulating member 50b and communicating with the current of the first power terminal 31b. Thus, while reducing the spacing between the first power terminal 31b and the second power terminal 32b in the second direction 002, the creepage distance between the first power terminal 31b and the second power terminal 32b is increased, further ensuring the use safety of the electronic device module 100 of the present application and further reducing the generation of stray inductance.
[0149] In one embodiment, as Figure 4 and Figure 13 shown, the surface of the second insulating protrusion 52b away from the first power terminal 31b is provided with a second groove 521b, and the surface of the second insulating protrusion 52b away from the second power terminal 32b is also provided with a second groove 521b. It can be understood that the provision of the second groove 521b further increases the creepage distance between the first power terminal 31b and the second power terminal 32b, further ensuring the use safety of the electronic device module 100 of the present application and further reducing the generation of stray inductance.
[0150] In one embodiment, the number of the second grooves 521b can be multiple. In another embodiment, the second groove 521b can also be provided only on the surface of the second insulating protrusion 52b away from the first power terminal 31b or on the surface of the second insulating protrusion 52b away from the second power terminal 32b. The present application does not make special restrictions on this.
[0151] In one embodiment, asFigure 2 and Figure 6 As shown in Figure 6 , the electronic device module 100 of the present application further includes a second insulating member 61, and the second insulating member 61 is fixed to the surface of the connecting portion 43 facing the first terminal 31. Since the current flow directions in the first terminal 31 and the second terminal 32 are different, and the connecting member 40 is electrically connected to the second terminal 32. It can be understood that the setting of the second insulating member 61 can prevent voltage breakdown of the gap between the connecting portion 43 and the first terminal 31, and prevent short circuit caused by the too close distance between the connecting portion 43 and the first terminal 31 in the second direction 002. Thus, the use safety of the electronic device module 100 of the present application is protected.
[0152] Meanwhile, the setting of the second insulating member 61 can also reduce the distance between the connecting portion 43 and the first terminal 31 on the premise of ensuring the safety distance between the connecting portion 43 and the first terminal 31 in the second direction 002, thereby reducing the inductance loop of the electronic device module 100 of the present application, so that the magnetic fields generated by the connecting portion 43 and the first terminal 31 can cancel each other out in a larger proportion, and further reduce the stray inductance of the electronic device module 100 of the present application.
[0153] In one embodiment, as shown in Figure 2 and Figure 6 As shown in Figure 6 , along the first direction 001, the length of the second insulating member 61 is greater than or equal to the distance between the capacitor insulating member 50a and the power insulating member 50b. So that the second insulating member 61 can cooperate with the capacitor insulating member 50a and the power insulating member 50b to further prevent voltage breakdown of the gap between the connecting portion 43 and the first terminal 31. Thus, the use safety of the electronic device module 100 of the present application is further protected.
[0154] Meanwhile, it can also further reduce the distance between the connecting portion 43 and the first terminal 31 to further reduce the inductance loop of the electronic device module 100 of the present application, and further reduce the stray inductance of the electronic device module 100 of the present application.
[0155] In one embodiment, as shown in Figure 2 and Figure 6 As shown in Figure 6 , along the third direction 003, the width of the second insulating member 61 is greater than or equal to the width of the connecting member 40. That is, in the third direction 003, the opposite ends of the second insulating member 61 protrude from the end faces of the connecting member 40 to further prevent voltage breakdown of the gap between the connecting portion 43 and the first terminal 31. Thus, the use safety of the electronic device module 100 of the present application is further protected.
[0156] Please refer to Figure 14 Another partial enlarged schematic diagram of the electronic device module 100 provided in an embodiment of the present application shown in Figure 14 .
[0157] As shown in Figure 14As shown, the electronic device module 100 of the present application further includes an insulating layer 62, and the insulating layer 62 is coated on the surface of the connecting portion 43 facing the first terminal 31. It can be understood that the setting of the insulating layer 62 can prevent voltage breakdown of the gap between the connecting portion 43 and the first terminal 31, and prevent short circuit caused by the too close distance between the connecting portion 43 and the first terminal 31 in the second direction 002. Thus, the use safety of the electronic device module 100 of the present application is protected.
[0158] At the same time, the setting of the insulating layer 62 can also reduce the distance between the connecting portion 43 and the first terminal 31 on the premise of ensuring the safety distance between the connecting portion 43 and the first terminal 31 in the second direction 002, thereby reducing the inductance loop of the electronic device module 100 of the present application, so that the magnetic fields generated by the connecting portion 43 and the first terminal 31 can cancel each other out in a larger proportion.
