[0063] In the embodiments of the present application, the terms "first", "second", "third", "fourth", "fifth", and "sixth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", "third", "fourth", "fifth", and "sixth" may explicitly or implicitly include one or more of such features.

[0064] In the embodiments of the present application, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0065] "A and / or B", including the following three combinations: only A, only B, and the combination of A and B.

[0066] In the embodiments of the present application, "parallel", "perpendicular", and "equal" include the described situations and situations similar to the described ones, and the range of the similar situations is within the acceptable deviation range, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of specific quantities (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallel and approximate parallel, and the acceptable deviation range of approximate parallel can be, for example, within a deviation of 5°; "perpendicular" includes absolute perpendicular and approximate perpendicular, and the acceptable deviation range of approximate perpendicular can also be, for example, within a deviation of 5°. "Equal" includes absolute equality and approximate equality, and the acceptable deviation range of approximate equality can be, for example, that the difference between the two equal ones is less than or equal to 5% of either one of them.

[0067] The embodiments of the present application can provide an electrical device, which can include a mobile phone, a computer, a vehicle, a ship, a household appliance, a mechanical device, an industrial device, etc. The embodiments of the present application will be described in detail with the electrical device being a vehicle.

[0068] It can be understood that the vehicle can be a fuel vehicle, an electric vehicle, a hybrid vehicle, a gas vehicle, a methanol vehicle, a solar vehicle, etc. The vehicle can be a passenger car such as a sedan, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), etc., or can also be a bus, a truck, a semi-trailer, an engineering vehicle, etc. The present application does not make specific restrictions on this.

[0069] Please refer to Figure 1 , Figure 1 FIG. 1000 is a schematic structural diagram of a vehicle 1000 provided by an embodiment of the present application. The vehicle 1000 can include a chassis, a vehicle body, and a controller.

[0070] Among them, the chassis 100 can install the motor and other components of the vehicle 1000, form the overall shape of the vehicle 1000, and receive the power of the motor to make the vehicle 1000 move and ensure normal driving.

[0071] The vehicle body 200 can be installed on the chassis 100. A passenger compartment is formed inside the vehicle body 200, and seats are provided in the passenger compartment for the driver and passengers to ride or load goods. It should be noted that when the vehicle 1000 is a bus or a sedan, its vehicle body 200 is generally an integral structure. When the vehicle 1000 is a truck, its vehicle body 200 is generally composed of a cab and a cargo box.

[0072] The controller 300 can be installed on the chassis 100. The controller 300 is used to manage the stability and handling of the vehicle 1000, including functions such as traction control (TCS), electronic stability control (ESP), and all-wheel drive (AWD). The controller 300 can also be responsible for the fuel injection, ignition timing, speed, and other parameters of the engine to optimize engine performance, improve fuel efficiency, and reduce emissions. The controller 300 is one of the most critical parts of the vehicle 1000.

[0073] It should be noted that the above components are only examples of some components of the vehicle 1000 and do not limit the specific structure of the vehicle 1000.

[0074] The controller 300 can include electronic devices, and different electronic devices can perform corresponding functions respectively. Exemplarily, the electronic device can be a DC support capacitor, and the DC support capacitor can provide protection for the module, absorb ripples, and prevent the module from being broken down due to high voltage. Exemplarily, the electronic device can also be a power module, and the function of the power module is to convert the power output and provide power input to the motor.

[0075] The different electronic devices are electrically connected by nuts in a one-to-one correspondence between the input terminals and the output terminals. Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of an electronic device in the related art. The output terminals 002 of the existing electronic device 001 are arranged side by side left and right, and openings are provided at the output end for nut connection.

[0076] In order to reserve the nut installation position, the terminals of the electronic device need to extend a certain length to make the connection between different electronic devices more stable. However, the extension of the terminal length will increase the inductance loop of the electronic device and generate redundant stray inductance.

[0077] In the circuit system of the controller 300, the inductance formed due to accidents or non-designed expectations is called stray inductance (SI). Stray inductance is usually generated due to the relative position between conductors, wiring layout, package design, or magnetic fields in the surrounding environment. The existence of stray inductance will cause problems such as losses or signal attenuation in the circuit system, affecting the stability of transmission.

[0078] Based on this, please refer to Figure 3 , Figure 3 which is a schematic structural diagram of a controller 300 provided by an embodiment of the present application. The controller 300 can include a first electronic device 01, a second electronic device 02, and a first connector 03.

[0079] Among them, the first electronic device 01 includes a first electronic device body and a first terminal 0101 connected to the first electronic device body. The second electronic device 02 includes a second electronic device body and a second terminal 0201 connected to the second electronic device body. The first electronic device body and the second electronic device body are stacked. In this way, the structure of the controller 300 is more compact, the connection loop between the first electronic device 01 and the second electronic device 02 can be shortened, thereby reducing stray inductance. In addition, the controller 300 can implement more functions within a limited space, meeting the requirements of miniaturized electronic products.

[0080] The first connector 03 is connected between the first terminal 0101 and the second terminal 0201, enabling the first electronic device 01 to be electrically connected or transmit signals. In this way, the overall circuit connection design can be simplified, the complexity of wiring can be reduced, and the assembly efficiency can be improved.

[0081] Among them, the first electronic device 01 can be a capacitor. Next, a first electronic device 01 provided by an embodiment of the present application will be introduced.

[0082] Please refer to Figure 4 , Figure 4 , which is a schematic structural diagram of an electronic device provided by an embodiment of the present application. The electronic device can include a body 11, a first busbar 12, and a second busbar 13. The first busbar 12 can include a first sub-busbar 121 and a second sub-busbar 122 connected to each other. The second busbar 13 can include a third sub-busbar 131 and a fourth sub-busbar 132 connected to each other. At least part of the body 11 is disposed between the first sub-busbar 121 and the third sub-busbar 131. The second sub-busbar 122 and the fourth sub-busbar 132 are stacked, and both the second sub-busbar 122 and the fourth sub-busbar 132 are disposed on the side of the first sub-busbar 121 facing away from the third sub-busbar 131, or both the second sub-busbar 122 and the fourth sub-busbar 132 are disposed on the side of the third sub-busbar 131 facing away from the first sub-busbar 121.

[0083] Among them, one of the first busbar 12 and the second busbar 13 can be connected to the positive electrode of the body 11, and the other of the first busbar 12 and the second busbar 13 can be connected to the negative electrode of the body 11. In this way, the first busbar 12 and the second busbar 13 can form the positive and negative input or output terminals of the electronic device. Disposing at least part of the body 11 between the first sub-busbar 121 and the third sub-busbar 131 can increase the contact area between the body 11 and the first sub-busbar 121 and the third sub-busbar 131, and can improve the response speed of the electronic device.

[0084] Since the second sub-row 122 is connected to the first sub-row 121 and the fourth sub-row 132 is connected to the third sub-row 131, the first electronic device 01 can be connected to the positive and negative terminals of the second electronic device 02 through the second sub-row 122 and the fourth sub-row 132 respectively to form an electrical connection.

[0085] Since the second electronic device 02 is stacked with the first electronic device 01, the second electronic device 02 can be located on the side of the first sub-row 121 facing away from the third sub-row 131, or on the side of the third sub-row 131 facing away from the first sub-row 121. Therefore, setting both the second sub-row 122 and the fourth sub-row 132 on the side of the first sub-row 121 facing away from the third sub-row 131, or setting both the second sub-row 122 and the fourth sub-row 132 on the side of the third sub-row 131 facing away from the first sub-row 121, can reduce the distance from the second sub-row 122 and the fourth sub-row 132 to the second electronic device 02, thereby shortening the lengths of the second sub-row 122 and the fourth sub-row 132 and reducing the generation of stray inductance in the transmission loop.

[0086] In addition, setting both the second sub-row 122 and the fourth sub-row 132 on the side of the first sub-row 121 facing away from the third sub-row 131, or on the side of the third sub-row 131 facing away from the first sub-row 121, can reduce the line redundancy from the first sub-row 121 to the second sub-row 122 and from the third sub-row 131 to the fourth sub-row 132, thereby also shortening the lengths of the second sub-row 122 and the fourth sub-row 132 and reducing the stray inductance in the loop.

[0087] The second sub-row 122 and the fourth sub-row 132 are stacked. One of the second sub-row 122 and the fourth sub-row 132 is connected to the positive electrode of the electronic device body 11, and the other is connected to the negative electrode of the electronic device body 11. Therefore, the inductance directions of the current circuits in the second sub-row 122 and the fourth sub-row 132 are opposite and can cancel each other out, thereby reducing the equivalent inductance loop formed between the first busbar 12 and the second busbar 13, and further improving the transmission stability of the electronic device.

[0088] Next, the present application will be specifically introduced with the first busbar 12 connected to the positive electrode of the body 11 and the second busbar 13 connected to the negative electrode of the body 11. It can be understood that the first busbar 12 can also be connected to the negative electrode of the body 11 and the second busbar 13 can be connected to the positive electrode of the body 11, and specific examples will not be given here.

[0089] In some embodiments, both the second sub-row 122 and the fourth sub-row 132 are provided on the side of the first sub-row 121 facing away from the third sub-row 131. The second sub-row 122 is connected to the first sub-row 121. The second busbar 13 includes a transition row 133, and the transition row 133 is connected between the third sub-row 131 and the fourth sub-row 132.

[0090] Since both the second sub-row 122 and the fourth sub-row 132 are disposed on the side of the first sub-row 121 facing away from the third sub-row 131, the second sub-row 122 and the first sub-row 121 are on the same side of the body 11, and the third sub-row 131 and the fourth sub-row 132 are on opposite sides of the body 11.

[0091] Connecting the second sub-row 122 to the first sub-row 121 can shorten the length of the first mother row 12, simplify the structure of the first mother row 12, and save production costs. Arranging a transition row 133 between the third sub-row 131 and the fourth sub-row 132 can connect the third sub-row 131 and the fourth sub-row 132, facilitating signal transmission.

[0092] In some other embodiments, when the second electronic device 02 is disposed on the side of the third sub-row 131 facing away from the first sub-row 121, both the second sub-row 122 and the fourth sub-row 132 can be disposed on the side of the third sub-row 131 facing away from the first sub-row 121, the fourth sub-row 132 is connected to the second sub-row 122, and the first mother row 12 includes a transition row 133 that is connected between the first sub-row 121 and the second sub-row 122.

[0093] In some embodiments, the transition row 133 can be disposed on the periphery of the body 11. The periphery of the body 11 can include the upper and lower surfaces of the body 11 and the outer peripheral surface of the body 11. Disposing the transition row 133 on the periphery of the body 11 can simplify the structure of the second mother row 13 and the body 11 and facilitate assembly.

[0094] In some other embodiments, an opening can be provided inside the body 11, and the transition row 133 can be passed through the body 11 to connect the third sub-row 131 and the fourth sub-row 132.

[0095] In some embodiments, the transition row 133 can include a first transition row 1331 and a second transition row 1332. The first transition row 1331 is disposed on the peripheral side of the body 11 and is connected to the third sub-row 131, and the second transition row 1332 is disposed on the side of the body 11 facing away from the third sub-row 131 and is connected to the first transition row 1331; the fourth sub-row 132 is connected to one end of the second transition row 1332 away from the first transition row 1331.

[0096] The third sub-row 131 and the fourth sub-row 132 are sequentially connected through the first transition row 1331 and the second transition row 1332. The first transition row 1331 is disposed on the peripheral side of the body 11, and the second transition row 1332 is disposed on the side of the body 11 facing away from the third sub-row 131, that is, the second transition row 1332 and the fourth sub-row 132 can be both disposed on one side of the body 11. By connecting through the first transition row 1331 and the second transition row 1332, the connection between the third sub-row 131 and the fourth sub-row 132 can be made more stable.

[0097] Since the body 11 is located on one side of the first sub-row 121 and is the positive electrode of the body 11, and the body 11 is located on one side of the third sub-row 131 and is the negative electrode of the body 11, and the transition row 133, as part of the second mother row 13, is located on the peripheral side of the body 11. Therefore, in some embodiments, the electronic device may further include a first insulating member, and the first insulating member is disposed between at least a part of the transition row 133 and the body 11. In this way, the first insulating member can insulate between the transition row 133 and the body 11, preventing the transition row 133 from contacting the surface of the positive electrode of the body 11 and causing short circuit to damage the electronic device.

[0098] In some other embodiments, the transition row 133 may also be spaced from the surface of the body 11. In this way, the surface of the body 11 can be prevented from contacting the transition row 133, preventing short circuit from damaging the electronic device.

[0099] In some embodiments, the first insulating member is disposed between the second transition row 1332 and the body 11. Since the positive electrode of the body 11 is the side of the body 11 close to the first sub-row 121, and the second transition row 1332 is disposed on the side of the body 11 facing away from the third sub-row 131 and there is a risk of contact short circuit with the positive electrode of the body 11. Therefore, the first insulating member is disposed between the second transition row 1332 and the body 11, which can prevent the second transition row 1332 from contacting and short-circuiting with the positive electrode of the body 11 and damaging the electronic device.

[0100] Exemplarily, the first insulating member may be a plastic film or a rubber sheet, or an insulating material is poured between the second transition member and the body 11 to insulate between the second transition row 1332 and the body 11.

[0101] Please continue to refer to Figure 4 , in some embodiments, the first sub-row 121 includes a first part 1211, a second part 1212 and a third part 1213. The second part 1212 and the third part 1213 are both located on the same side of the first part 1211 and are connected to the first part 1211, and the second part 1212 and the third part 1213 are spaced apart. The second sub-row 122 is connected to the edge of the first part 1211 located between the second part 1212 and the third part 1213, and the second transition row 1332 is located between the second part 1212 and the third part 1213. One end of the second transition row 1332 away from the first part 1211 is connected to the first transition row 1331, and the fourth sub-row 132 is connected to one end of the second transition row 1332 facing the first part 1211.

[0102] The second part 1212 and the third part 1213 can increase the contact area between the first sub-row 121 and the body 11, reduce the risk of poor contact, and reduce current instability, signal loss, or noise generated due to poor contact. At the same time, the second part 1212 and the third part 1213 are arranged at intervals and are both located on one side of the first part 1211. In this way, the first part 1211, the second part 1212, and the third part 1213 can enclose an avoidance opening, which can leave an avoidance space for the second sub-row 122, the fourth sub-row 132, and the second transition row 1332, making the layout of the first mother row 12 and the second mother row 13 more reasonable.

[0103] In addition, the second sub-row 122 is connected to the edge of the first part 1211 between the second part 1212 and the third part 1213, and the fourth sub-row 132 is connected to one end of the second transition row 1332 facing the first part 1211, which can make the second sub-row 122 and the fourth sub-row 132 arranged opposite to each other. In this way, it is convenient for the second sub-row 122 and the fourth sub-row 132 to be stacked, reducing the stray inductance in the circuit.

[0104] It should be noted that the second part 1212 and the third part 1213 can also be an integral structure. The second part 1212 and the third part 1213 can be arranged on the surface of the body 11, and the second transition row 1332 is arranged on the side of the second part 1212 and the third part 1213 facing away from the body 11. In this way, the contact area between the first sub-row 121 and the body 11 can be further increased.

[0105] When the second transition row 1332 is arranged on the side of the second part 1212 and the third part 1213 facing away from the body 11, along the arrangement direction of the first sub-row 121 and the third sub-row 131, the second transition row 1332 is arranged at intervals with the second part 1212 and the third part 1213, so that the second transition row 1332 is insulated from the second part 1212 and the third part 1213.

[0106] A first insulating member can also be arranged between the second transition row 1332 and the second part 1212 and the third part 1213, so that the second transition row 1332 is further insulated from the second part 1212 and the third part 1213, preventing a short circuit between the positive and negative electrodes.

[0107] Please refer to Figure 4 and Figure 5 , Figure 5 for Figure 4Schematic diagram of the structure of the electronic device shown from another angle. In some embodiments, the second sub-row 122 may include a first terminal row portion 1221, and the fourth sub-row 132 includes a second terminal row portion. Along the stacking direction of the first sub-row 121 and the third sub-row 131, the distance from the first terminal row portion to the first sub-row 121 is equal to the distance from the second terminal row portion to the first sub-row 121.

[0108] Since the first electronic device 01 and the second electronic device 02 are stacked, along the stacking direction of the first sub-row 121 and the third sub-row 131, the distance from the first terminal row portion to the first sub-row 121 is equal to the distance from the second terminal row portion to the first sub-row 121, which can make the first terminal row portion and the second terminal row portion be arranged at the same plane height. When the second electronic device 02 is connected to the first terminal row portion and the second terminal row portion, the number of times of positioning in the height direction is reduced, making the connection more convenient.

[0109] In some embodiments, the first terminal row portion, the second terminal row portion and the first sub-row 121 are all arranged in parallel. The first terminal row portion is arranged in parallel with the first sub-row 121, and the second terminal row portion is also arranged in parallel with the first sub-row 121. In this way, the contact area between the first terminal row portion, the second terminal row portion and the first connector 03 can be increased, making the connection more stable and preventing the risk of circuit failure or unstable transmission due to poor contact.

[0110] In some embodiments, the second sub-row 122 may further include a first connection row 1222, and the first connection row 1222 is connected between the first terminal row portion and the first sub-row 121, and the first connection row 1222 is perpendicular or intersects with the first sub-row 121; and / or, the fourth sub-row 132 further includes a second connection row 1322, and the second connection row 1322 is connected between the second terminal row portion and the second transition row 1332, and the second connection row 1322 is perpendicular or intersects with the second transition row 1332.

[0111] The first connection row 1222 and the second connection row 1322 can be used to support the first terminal row portion and the second terminal row portion, so that the first terminal row portion and the second terminal row portion are close to the second electronic device 02, facilitating the connection between the first electronic device 01 and the second electronic device 02. The first connection row 1222 and the second connection row 1322 can also be used to transmit signals to transfer the signals on the first sub-row 121 and the second transition row 1332 to the first terminal row portion and the second terminal row portion.

[0112] In addition, the first connection row 1222 is perpendicular to or intersects the first sub-row 121, and the second connection row 1322 is perpendicular to or intersects the second transition row 1332. In this way, the positions and angles of the first terminal row portion and the second terminal row portion can be changed through the first connection row 1222 and the second connection row 1322, so as to adapt to different processing scenarios and usage scenarios.

[0113] Exemplarily, the first connection row 1222 is perpendicular to the first sub-row 121, and the second connection row 1322 is perpendicular to the second transition row 1332, which is convenient for processing and can improve processing efficiency.

[0114] Since the first terminal row portion and the second terminal row portion are respectively parts of the first mother row 12 and the second mother row 13, the first terminal row portion and the second terminal row portion can form a positive terminal and a negative terminal of the electronic device. Since the electronic device can include an input terminal and an output terminal, in some embodiments, the electronic device can further include a first external terminal 14 and a second external terminal 15. The first external terminal 14 and the second external terminal 15 are located on the side of the second transition row 1332 facing away from the body 11 and are electrically connected to the body 11.

[0115] In this way, the first external terminal 14 and the second external terminal 15 can form one of the input terminal and the output terminal, and the first terminal row portion and the second terminal row portion can form the other of the input terminal and the output terminal, so that the electronic device can receive signals and transfer the signals to the next link.

[0116] By arranging the first external terminal 14 and the second external terminal 15 on the side of the second transition row 1332 facing away from the body 11, in this way, the first external terminal 14, the second external terminal 15, the second sub-row 122 and the fourth sub-row 132 are all located on one side of the body 11, which can make the layout of the electronic device more compact and facilitate the connection of the electronic device to other components.

[0117] In some embodiments, the first mother row 12 and the second mother row 13 form the output terminal of the body 11, and the first external terminal 14 and the second external terminal 15 form the input terminal of the body 11.

[0118] In this way, the first mother row 12 and the second mother row 13 can be used to transfer the signals processed by the electronic device to the next electronic device unit, and the first external terminal 14 and the second external terminal 15 can be used to receive signals, so that the electronic device can process the given signals.

[0119] In other embodiments, the first mother row 12 and the second mother row 13 form the input terminal of the body 11, and the first external terminal 14 and the second external terminal 15 form the output terminal of the body 11.

[0120] Please refer to Figures 4 - 6 , Figure 6 the structure schematic diagram of the electronic device shown Figure 4 from another angle. In some embodiments, the electronic device may further include a second insulating member 16, and at least a part of the second insulating member 16 is disposed between the second sub-row 122 and the fourth sub-row 132.

[0121] Since the second sub-row 122 is connected to the positive electrode of the body 11 and the fourth sub-row 132 is connected to the negative electrode of the body 11, disposing at least a part of the second insulating member 16 between the second sub-row 122 and the fourth sub-row 132 can insulate and isolate the second sub-row 122 and the fourth sub-row 132, thereby preventing direct contact between the positive and negative electrodes from causing a short circuit and damaging the electronic device.

[0122] In some embodiments, the second insulating member 16 includes an insulating isolation portion 161, and the insulating isolation portion 161 is disposed between the first terminal row portion 1221 and the second terminal row portion 1321.

[0123] In this way, the second sub-row 122 and the fourth sub-row 132 can be fully isolated, preventing high-voltage arcing between the first terminal row portion 1221 and the second terminal row portion 1321.

[0124] In some embodiments, the dimension of the insulating isolation portion 161 along the stacking direction of the first sub-row 121 and the third sub-row 131 is greater than the thickness of the first terminal row portion 1221 and the second terminal row portion 1321.

[0125] In this way, the insulating isolation portion 161 can extend beyond the first terminal row portion 1221 and the second terminal row portion 1321, enabling full insulation between the first terminal row portion 1221 and the second terminal row portion 1321 and further preventing high-voltage creepage and arcing.

[0126] In some embodiments, the electronic device may further include a limiting portion 162, and the limiting portion 162 is located at opposite ends of the first terminal row portion 1221 and / or the second terminal row portion 1321 along a first direction; wherein, the first direction is perpendicular to the stacking direction of the first sub-row 121 and the third sub-row 131 and perpendicular to the arrangement direction of the first terminal row portion 1221 and the second terminal row portion 1321.

[0127] The limiting part 162 is arranged at both ends of the first terminal row part 1221 and / or the second terminal row part 1321. Since the first connecting piece 03 is lapped on the first terminal 0101 of the first electronic device 01, one of the first terminal row part 1221 and the second terminal row part 1321 can form the first terminal 0101. Therefore, the limiting part 162 can limit the first connecting piece 03 to prevent misalignment or deviation of the first connecting piece 03 when connecting the first electronic device 01 and the second electronic device 02, resulting in poor connection.

[0128] In some embodiments, the electronic device may further include a third insulating member 17, and at least a part of the third insulating member 17 is arranged between the first external terminal 14 and the second external terminal 15.

[0129] Since the first external terminal 14 and the second external terminal 15 respectively form the positive pole and the negative pole of a set of terminals of the electronic device, therefore, arranging at least a part of the third insulating member 17 between the first external terminal 14 and the second external terminal 15 can insulate and isolate the first external terminal 14 and the second external terminal 15, preventing direct contact between the positive and negative poles from causing a short circuit and damaging the electronic device.

[0130] In some embodiments, the first insulating member, the second insulating member 16 and the third insulating member 17 may be of an integral structure. In this way, the connection gaps between the insulating members can be reduced, the occurrence of situations such as leakage and high-voltage arcing can be reduced, and the insulation isolation can be made more sufficient.

[0131] Exemplarily, the first insulating member, the second insulating member 16 and the third insulating member 17 can be formed by injection molding. After connecting the body 11, the first bus bar 12 and the second bus bar 13, place the body 11, the first bus bar 12 and the second bus bar 13 in an injection mold, and add insulating materials such as epoxy resin into the mold to form the first insulating member, the second insulating member 16 and the third insulating member 17 of an integral structure.

[0132] In some embodiments, the body 11 is provided with a first potting hole, the first sub-row 121 is provided with a second potting hole, the third sub-row 131 is provided with a third potting hole, and the first potting hole, the second potting hole and the third potting hole are opposite and communicate with each other.

[0133] In this way, a flow channel can be provided for the insulating filler so that the insulating filler can fully flow into each gap, thereby making the insulation more sufficient.

[0134] Among them, the material of the insulating filler can be epoxy resin, polyester resin or silica gel, etc., and the present application does not make further limitations in this regard.

[0135] Please refer to Figure 3 、 Figure 7 and Figure 8, Figure 7 is Figure 3 an assembly schematic diagram of the controller 300 shown Figure 8 is Figure 7 a partial enlarged view of the controller 300 shown at A. In the embodiment of the present application, the second electronic device body and the first electronic device body are arranged along the second direction, and the second terminal 0201 and the first terminal 0101 are arranged along the third direction perpendicular to the second direction. That is, the arrangement direction of the first terminal 0101 and the second terminal 0201 is perpendicular to the arrangement direction of the first electronic device body and the second electronic device body. In this way, when connecting the first electron and the second electron, there is no need to repeatedly perform positioning along the arrangement direction of the first electronic device body and the second electronic device body, the connection is more convenient, and the connection efficiency is improved.

[0136] In addition, the first connecting member 03 can be in the shape of a flat sheet, and the first connecting member 03 is connected between the first terminal 0101 and the second terminal 0201. Since the first terminal 0101 and the second terminal 0201 are arranged in parallel, therefore, setting the first connecting member 03 as a flat sheet can enable the connecting device to directly move from above the first terminal 0101 to above the second terminal 0201, completing the connection work of the first connecting member 03 with the first terminal 0101 and the second electron, making the connection operation simpler and facilitating automated production and processing.

[0137] Please refer to Figures 3 - 8 , where one of the first bus bar 12 and the second bus bar 13 of the electronic device provided in the above embodiment can constitute the first terminal 0101 and can be connected to the second electronic device 02 through the first connecting member 03.

[0138] Please refer to Figure 8 and Figure 9 , Figure 9 is a structural schematic diagram of a first connecting member 03 provided in the embodiment of the present application. In some embodiments, the first terminal 0101 and the first connecting member 03, and the second terminal 0201 and the first connecting member 03 can be connected by laser welding. In this way, the extension of the terminal caused by nut connection can be reduced, thereby shortening the connection loop of the electronic device and reducing the stray inductance caused by the increase of the loop. In addition, since the nut connection may be loose during use, resulting in poor current capacity, causing the electronic device to generate arcs or open circuits, resulting in unstable transmission. By using the laser welding method for the first connecting member 03 with the first terminal 0101 and the second terminal 0201, the connection stability is good and the connection is precise, thereby improving the signal transmission stability between the electronic devices.

[0139] In addition, the first terminal 0101 and the first connecting member 03, as well as the second terminal 0201 and the first connecting member 03, can be joined by ultrasonic welding, spot welding, etc. This application does not limit this, and it is specifically set according to the actual needs.

[0140] In some embodiments, the first connecting member 03 includes a connected first connecting portion 031 and a second connecting portion 032. The first connecting portion 031 is connected to the first terminal 0101, and the second connecting portion 032 is connected to the second terminal 0201. The first connecting portion 031 and the second connecting portion 032 are located in the same plane. In this way, the structure of the first connecting member 03 is simple, facilitating manufacturing and processing.

[0141] In some embodiments, the first connecting portion 031 is welded to the first terminal 0101, and the second connecting portion 032 is welded to the second terminal 0201. In this way, the connection strength between the first connecting portion 031 and the first terminal 0101, as well as the connection strength between the second connecting portion 032 and the second terminal 0201, can be enhanced, preventing poor overcurrent capacity and open circuits in the circuit connection due to unstable connection.

[0142] In addition, since the first connecting portion 031 and the first terminal 0101 can be laser welded, and the second connecting portion 032 can be laser welded to the second terminal 0201, thus, by arranging the first connecting portion 031 and the second connecting portion 032 in the same plane, the first connecting member 03, the first terminal 0101, and the second terminal 0201 can be laser scanned once to improve the welding efficiency. At the same time, the welding quality risk caused by switching welding due to different distances from the laser source to the target surface to be welded can be avoided.

[0143] In some embodiments, the first electronic device 01 can be provided with a first positioning portion, and a first positioning hole 0311 is provided on the first connecting portion 031. The first positioning hole 0311 can be connected to the first positioning portion provided on the first electronic device 01. In this way, the first positioning portion can limit the first connecting member 03, preventing poor welding caused by misalignment or offset of the connection of the first connecting member 03.

[0144] Among them, in the electronic device provided in the above embodiments, the limiting portions 162 at the opposite ends of the first terminal row portion 1221 along the first direction can constitute the first positioning portion, so as to cooperate with the first positioning hole 0311 through the limiting portion 162 to limit the first connecting member 03.

[0145] In some embodiments, the first connecting portion 031 can be provided in multiple numbers, and the multiple first connecting portions 031 are arranged at intervals along the first direction, and the first direction is perpendicular to the arrangement direction from the first connecting portion 031 to the second connecting portion 032.

[0146] In this way, the deformation stress generated by the compression of the first connection part 031 during laser welding can be reduced, so that the first connection part 031 can fully form a surface contact with the first terminal 0101, so as to avoid welding explosion holes or false soldering caused by insufficient contact between the first connection part 031 and the first terminal 0101.

[0147] It can be understood that multiple second connection parts 032 can also be provided, and the multiple second connection parts 032 can be arranged at intervals along the first direction.

[0148] Please continue to refer to Figure 10 and Figure 11 , Figure 10 is Figure 7 a further assembly schematic diagram of the controller 300 shown in Figure 11 is Figure 10 a partial enlarged view of the controller 300 shown in at B. In some embodiments, the first electronic device 01 may further include a third terminal 0102 connected to the first electronic device body, and the second electronic device 02 may further include a fourth terminal 0202 connected to the second electronic device body. The third terminal 0102 is located on the side of the first terminal 0101 facing away from the second terminal 0201, and the fourth terminal 0202 is located on the side of the second terminal 0201 facing away from the first terminal 0101. The controller 300 further includes a second connecting member 04, and the second connecting member 04 is connected between the third terminal 0102 and the fourth terminal 0202.

[0149] It can be understood that the first terminal 0101 may be the positive terminal of the first electronic device 01, and the third terminal 0102 may be the negative terminal of the first electronic device 01. In this way, since the first terminal 0101 is connected to the second terminal 0201 and the third terminal 0102 is connected to the fourth terminal 0202, therefore, the second terminal 0201 may be the positive terminal of the second electronic device 02, and the fourth terminal 0202 may be the negative terminal of the second electronic device 02. The first terminal 0101 and the second terminal 0201 may also be used as negative terminals, and the third terminal 0102 and the fourth terminal 0202 may be positive terminals.

[0150] In this application, the first terminal 0101 and the second terminal 0201 are used as positive terminals, and the third terminal 0102 and the fourth terminal 0202 are used as negative terminals as an example for specific introduction. The first terminal 0101 and the second terminal 0201 being used as negative terminals, and the third terminal 0102 and the fourth terminal 0202 being used as positive terminals can be obtained by simple replacement, and will not be elaborated here.

[0151] Since the first connector 03 and the second connector 04 are respectively connected to the positive and negative electrodes of the first electronic device 01, if there is interference between the first connector 03 and the second connector 04, it will cause a short circuit in the controller 300 and damage the controller 300.

[0152] By arranging the third terminal 0102 on the side of the first terminal 0101 facing away from the second terminal 0201, and arranging the fourth terminal 0202 on the side of the second terminal 0201 facing away from the first terminal 0101, it is convenient to arrange the first connector 03 and the second connector 04, and prevent interference between the first connector 03 and the second connector 04 caused by the alternating arrangement of the third terminal 0102, the fourth terminal 0202 and the first terminal 0101, the second terminal 0201, so that the connection between the first electronic device 01 and the second electronic device 02 is more convenient and the layout of the controller 300 is more reasonable.

[0153] In some embodiments, the two ends of the second connector 04 are respectively connected to the third terminal 0102 and the fourth terminal 0202, and the middle part of the second connector 04 is located on the side of the first connector 03 facing away from the first terminal 0101 and the second terminal 0201.

[0154] In this way, the middle part of the second connector 04 is located on the side of the first connector 03 facing away from the first terminal 0101 and the second terminal 0201, which can prevent interference between the first connector 03 and the second connector 04, and can stably connect the third terminal 0102 and the fourth terminal 0202 to ensure the normal transmission of signals.

[0155] Please refer to Figures 10 - 12 , Figure 12 FIG. is a schematic structural diagram of a second connector 04 provided by an embodiment of the present application. In some embodiments, the second connector 04 may include a third connection portion 041 connected to the third terminal 0102, a fourth connection portion 042 connected to the fourth terminal 0202, and a fifth connection portion 043 connected between the third connection portion 041 and the fourth connection portion 042. The fifth connection portion 043 is arranged at an interval from the first connector 03 in the second direction.

[0156] In this way, the fifth connection part 043 can be used to connect the third connection part 041 and the fourth connection part 042, so as to electrically connect the third terminal 0102 and the fourth terminal 0202, thereby realizing signal transmission between the first electronic device 01 and the second electronic device 02. Since the current directions in the first connection member 03 and the second connection member 04 are opposite, the fifth connection part 043 and the first connection member 03 are arranged along the second direction, which can reduce the stray inductance in the circuit. In addition, since the first connection member 03 and the second connection member 04 are respectively connected to the positive terminal and the negative terminal, the fifth connection part 043 and the first connection member 03 are arranged at intervals, so that the first connection member 03 and the second connection member 04 are insulated, preventing the circuit of the controller 300 from being short-circuited.

[0157] In some embodiments, the third connection part 041 is welded to the third terminal 0102, and the fourth connection part 042 is welded to the fourth terminal 0202. In this way, the connection strength between the third connection part 041 and the third terminal 0102, and the connection strength between the fourth connection part 042 and the fourth terminal 0202 can be enhanced, preventing poor overcurrent capacity and open circuit in the circuit connection due to unstable connection.

[0158] In some embodiments, the second electronic device 02 is provided with a second positioning part, and the fifth connection part 043 is provided with a second positioning hole 0431, and the second positioning hole 0431 is connected to the second positioning part. In this way, the second positioning part can limit the second connection member 04, preventing poor soldering caused by misalignment or deviation of the second connection member 04 during connection.

[0159] In some other embodiments, the limiting parts 162 at the opposite ends of the second terminal row part 1321 of the first electronic device 01 along the first direction can also constitute the second positioning part, and the second positioning hole 0431 is arranged on the third connection part 041, so as to limit the second connection member 04 by the cooperation of the limiting part 162 and the second positioning hole 0431.

[0160] In some embodiments, the number of the third connection parts 041 is multiple, and the multiple third connection parts 041 are arranged at intervals along the first direction, and the first direction is perpendicular to the arrangement direction of the third connection part 041 to the fourth connection part 042.

[0161] In this way, the deformation stress generated by the fourth connection part 042 under pressure during laser welding can be reduced, so that the fourth connection part 042 can fully form a surface contact with the third terminal 0102, avoiding welding explosion holes or false soldering due to insufficient contact between the third connection part 041 and the third terminal 0102.

[0162] It can be understood that the fourth connection portion 042 can also be provided in plurality, and the plurality of fourth connection portions 042 can be arranged at intervals along the first direction.

[0163] Please refer to Figure 10 In some embodiments, the controller 300 may further include a fourth insulating member 05, which is disposed between the first connector 03 and the second connector 04. Since the first connector 03 and the second connector 04 are connected to the positive terminal and the negative terminal, respectively, the fourth insulating member 05 is disposed between the first connector 03 and the second connector 04, so that the first connector 03 and the second connector 04 can be further insulated, thereby preventing the first connector 03 and the second connector 04 from arcing due to poor insulation.

[0164] Please refer to Figure 10 , Figure 11 as well as Figure 13 , Figure 13 This is a schematic structural diagram of a second electronic device 02 provided in an embodiment of the present application. In some embodiments, along the second direction, the second terminal 0201 and the fourth terminal 0202 are spaced apart, and at least a portion of the second terminal 0201 is stacked with the fourth terminal 0202 .

[0165] The second terminal 0201 and the fourth terminal 0202 are arranged at intervals, so that the second terminal 0201 and the fourth terminal 0202 can be insulated to prevent a short circuit in the controller 300. The second terminal 0201 and the fourth terminal 0202 are arranged in a stacked manner, and since the current directions in the second terminal 0201 and the fourth terminal 0202 are opposite, the magnetic fields generated are opposite in direction, so they can cancel each other out, thereby reducing the stray inductance of the controller 300.

[0166] In addition, in some embodiments, the second terminal 0201 and the fourth terminal 0202 may be staggered along the arrangement direction from the first connection portion 031 to the second connection portion 032 , so that the spacing distance between the second terminal 0201 and the fourth terminal 0202 may be shortened.

[0167] In some other embodiments, the ends of the second terminal 0201 and the fourth terminal 0202 may also extend in opposite directions, that is, the second terminal 0201 and the fourth terminal 0202 are not stacked, and the present application does not impose any limitation on this, and it can be arranged according to actual needs.

[0168] In some embodiments, the second electronic device 02 further includes a fifth insulating member 021 , and the fifth insulating member 021 is disposed between the second terminal 0201 and the fourth terminal 0202 .

[0169] In this way, the second terminal 0201 and the fourth terminal 0202 can be sufficiently insulated from each other, so that the relative distance between the second terminal 0201 and the fourth terminal 0202 can be minimized as much as possible, the connection loop can be shortened, and the stray inductance can be reduced accordingly.

[0170] Please refer to Figure 3 、 Figure 7 and Figure 10 , in some embodiments, the controller 300 may further include a heat sink 06. The first electronic device body, the heat sink 06, and the second electronic device body are arranged along a second direction, and the heat sink 06 is disposed between the first electronic device body and the second electronic device body.

[0171] In this way, the heat sink 06 can absorb the heat generated by the first electronic device body and the second electronic device body during operation, quickly transfer the heat out, and reduce the operating temperatures of the first electronic device body and the second electronic device body.

[0172] Exemplarily, the heat sink 06 may include a heat dissipation plate, and a water cooling channel is provided inside the heat dissipation plate. Through the water circulation inside the heat dissipation plate, the coolant in the water cooling channel can exchange heat with the first electronic device body and the second electronic device body, thereby realizing the cooling of the controller 300.

[0173] The first electronic device body, the heat sink 06, and the second electronic device body are arranged along the second direction, which can increase the contact area between the heat sink 06 and the first electronic device body and the second electronic device body, improve the heat conduction performance, and enhance the heat dissipation efficiency.

[0174] Please refer to Figure 10 、 Figure 11 and Figure 14 and Figure 15 , Figure 14 FIG. shows a schematic structural diagram of a base 07 provided by an embodiment of the present application. Figure 15 is Figure 14 a schematic structural diagram of the base 07 shown in another angle. In some embodiments, the controller 300 may further include a base 07. The base 07 has a first surface 071 and a second surface 072 facing away from each other. At least a part of the first electronic device 01 is disposed on the first surface 071, and the second electronic device 02 is disposed on the second surface 072. The base 07 is further provided with a connection opening 073 communicating the first surface 071 and the second surface 072. The first terminal 0101 and the third terminal 0102 are connected to the second electronic device 02 through the connection opening 073.

[0175] In this way, the first electronic device 01 and the second electronic device 02 can be distributed on both sides of the base 07, effectively saving space and enabling more functions to be integrated within a limited space.

[0176] An opening communicating the first surface 071 and the second surface 072 is provided on the base 07, which facilitates the connection between the first electronic device 01 and the second electronic device 02. The connection can be made without having to bypass the edge of the base 07, resulting in a more reasonable spatial layout. At the same time, the first terminal 0101 and the third terminal 0102 can be directly connected to the second electronic device 02 through the connection opening 073, which can shorten the lengths of the first terminal 0101 and the second terminal 0201, thereby reducing the stray inductance in the circuit.

[0177] In some embodiments, the base 07 includes a mounting groove 074 protruding towards the second surface 072. At least a part of the first electronic device 01 is disposed in the mounting groove 074, and the second electronic device 02 is disposed on the side of the mounting groove 074 away from the first electronic device 01.

[0178] In this way, disposing at least a part of the first electronic device 01 in the mounting groove 074 can facilitate the positioning and installation of the first electronic device, making the structure of the controller 300 more precise and more reliable.

[0179] In some embodiments, the connection opening 073 can be provided on the wall surface of the mounting groove 074 between the first electronic device 01 and the second electronic device 02.

[0180] Since the second sub-row 122 and the fourth sub-row 132 of the first electronic device 01 can be disposed on the side of the first sub-row 121 away from the third sub-row 131, therefore, by providing the connection opening 073 on the wall surface between the first electronic device 01 and the second electronic device 02, the first sub-row 121 can be close to the wall surface between the first electronic device 01 and the second electronic device 02, and the second sub-row 122 and the fourth sub-row 132 can extend through the connection opening 073 to the wall surface to be connected to the second electronic device 02. In this way, the lengths of the second sub-row 122 and the fourth sub-row 132 can be shortened, the stray inductance in the circuit can be reduced, and the stability and reliability of the controller 300 can be improved.

[0181] In some other embodiments, the arrangement directions of the second sub-row 122 and the fourth sub-row 132 of the first electronic device 01 to the body 11 can also be perpendicular to the arrangement direction of the first sub-row 121 to the third sub-row. Therefore, the connection opening 073 can also be provided on the base 07, and the arrangement directions of the mounting groove 074 and the connection opening 073 intersect with the arrangement directions of the first electronic device 01 and the second electronic device 02. In this way, the second sub-row 122 and the fourth sub-row 132 can extend through the connection opening 073 to the side of the base 07 where the second electronic device 02 is located, facilitating the connection between the first electronic device 01 and the second electronic device 02.

[0182] In some embodiments, the base 07 can be made of metal. Since metal has better thermal conductivity compared to materials such as plastic, the base 07 can better exchange heat with the first electronic device 01 and the second electronic device 02, so as to transfer the heat generated by the first electronic device 01 and the second electronic device 02 during operation to the air, preventing the performance degradation caused by heat accumulation in the controller 300.

[0183] In some embodiments, a cooling water channel 075 is provided in the base 07, and at least part of the cooling water channel 075 is disposed between the bottom wall of the mounting groove 074 and the second surface 072. In this way, coolant can be injected into the cooling water channel 075, and heat exchange is performed between the coolant and the first electronic device 01 and the second electronic device 02, thereby cooling the controller 300 and ensuring the normal operation of the controller 300.

[0184] In some embodiments, a sixth insulating member is provided between the first electronic device 01 and the base 07. The insulating member can insulate the first electronic device 01 and the base 07, preventing the first electronic device 01 from conducting electricity with the base 07 and causing leakage or signal transmission failure of the controller 300.

[0185] Exemplarily, the sixth insulating member can be a plastic cover plate, a rubber sheet or a silica gel pad, etc. The sixth insulating member can be filled between the first surface 071 and the first electronic device 01, and between the inner wall of the mounting groove 074 and the peripheral wall of the first electronic device 01.

[0186] In some embodiments, a packaging material can also be provided in the mounting groove 074. The packaging material is filled between the first electronic device 01 and the inner wall surface of the mounting groove 074. The packaging material can encapsulate the first electronic device 01, provide additional mechanical support for the first electronic device 01, effectively fix the first electronic device 01, reduce the influence of vibration and shock, and enhance the overall stability. The packaging material can also protect the first electronic device 01, prevent dust, moisture and other external pollutants from damaging the first electronic device 01, and enhance the environmental resistance of the first electronic device 01.

[0187] In addition, the packaging material can also insulate the first electronic device 01 from the base 07, preventing leakage or short circuit of the controller 300.

[0188] Exemplarily, the packaging material can be epoxy resin, silica gel or polyester resin, etc. The present application does not make further limitations thereto.

[0189] Please refer to Figure 4 、 Figure 16 and Figure 17 , Figure 16Schematic diagram of another first electronic device 01 provided by the embodiments of the present application. Figure 17 is Figure 16 Partial schematic diagram of the first electronic device 01 shown in the application to the controller 300. The embodiments of the present application also provide another first electronic device 01, which may also include a body 11, a first busbar 12, and a second busbar 13. The first busbar 12 may include a first sub-busbar 121 and a second sub-busbar 122 connected to each other. The second busbar 13 may include a third sub-busbar 131 and a fourth sub-busbar 132 connected to each other.

[0190] Among them, the body 11 is disposed between the first sub-busbar 121 and the third sub-busbar 131, and the positive electrode of the body 11 is connected to the first sub-busbar 121, and the negative electrode of the body 11 is connected to the third sub-busbar 131, or the negative electrode of the body 11 is connected to the first sub-busbar 121, and the positive electrode of the body 11 is connected to the third sub-busbar 131.

[0191] The fourth sub-busbar 132 and the second sub-busbar 122 are stacked, and the arrangement directions of the second sub-busbar 122 and the fourth sub-busbar 132 with respect to the body 11 intersect the arrangement directions of the first sub-busbar 121 and the third sub-busbar 131. Among them, one of the first busbar 12 and the second busbar 13 forms a first terminal 0101.

[0192] The fourth sub-busbar 132 and the second sub-busbar 122 are stacked, and the inductance directions generated by the current circuits in the second sub-busbar 122 and the fourth sub-busbar 132 are opposite to each other and cancel each other out, reducing the stray inductance generated in the loop, thereby improving the transmission stability of the first electronic device 01.

[0193] In addition, the second sub-busbar 122 and the fourth sub-busbar 132 are disposed outside the body 11, which can increase the connection area between the first busbar 12 and the second busbar 13, reduce the risk of poor contact, and avoid problems such as unstable current, signal loss, or noise generation due to poor contact.

[0194] In some embodiments, the first sub-busbar 121 includes a connection portion 123 and an extension portion 124. The connection portion 123 is connected to the positive electrode of the body 11, and the extension portion 124 is connected between the connection portion 123 and the second sub-busbar 122.

[0195] The extension portion 124 is used to connect the connection portion 123 and the second sub-busbar 122, so that the signal in the body 11 can be transmitted to the second electronic device 02 through the connection portion 123, the extension portion 124, and the second sub-busbar 122 in sequence. The extension portion 124 can facilitate signal transmission.

[0196] In some embodiments, the extension portion 124 includes a first extension portion 1241 and a second extension portion 1242. The first extension portion 1241 is connected to the first sub-row 121 and is located on the circumferential side of the body 11. The second extension portion 1242 is connected to the first extension portion 1241, and the second extension portion 1242 is arranged in parallel with the third sub-row 131.

[0197] The first extension portion 1241 is located on the circumferential side of the body 11, and can extend the first sub-row 121 in the direction towards the third sub-row 131. In this way, when the first electronic device 01 is installed in the installation groove 074, both the second sub-row 122 and the fourth sub-row 132 can extend out of the connection opening 073 and be connected to the second electronic device 02. Thus, the layout of the controller 300 can be made simpler.

[0198] In addition, the second extension portion 1242 is connected to the first extension portion 1241, and the second extension portion 1242 is arranged in parallel with the third sub-row 131, which can space the second sub-row 122 from the first extension portion 1241 to prevent signal interference or short circuit between the second sub-row 122 and the first extension portion 1241.

[0199] In some embodiments, the second sub-row 122 includes a first terminal row portion 1221, and the fourth sub-row 132 includes a second terminal row portion. Along the stacking direction of the first sub-row 121 and the third sub-row 131, the distance from the first terminal row portion to the first sub-row 121 is greater than the distance from the second terminal row portion to the first sub-row 121. In this way, the distances from the first terminal row portion and the second terminal row portion to the first sub-row 121 are inconsistent, which is convenient for their stacked arrangement, so that the connection between the first terminal row portion and the second terminal row portion and the second electronic device 02 is more convenient and the generated stray inductance is less.

[0200] In some embodiments, the first terminal row portion and the second terminal row portion are stacked.

[0201] Since the inductance directions generated by the current circuits in the first terminal row portion and the second terminal row portion are opposite to each other, they can cancel each other out when the first terminal row portion and the second terminal row portion are stacked, thereby reducing the equivalent inductance loop formed between the first bus bar 12 and the second bus bar 13, and further improving the transmission stability of the electronic device.

[0202] In some embodiments, the second sub-row 122 further includes a first connection row 1222. The first connection row 1222 is connected between the first terminal row portion and the extension portion 124, and the first connection row 1222 is perpendicular or intersects with the first sub-row 121; and / or, the fourth sub-row 132 further includes a second connection row 1322. The second connection row 1322 is connected between the second terminal row portion and the third sub-row 131, and the second connection row 1322 is perpendicular or intersects with the third sub-row 131.

[0203] The first connection row 1222 and the second connection row 1322 can be used to support the first terminal row part and the second terminal row part, so that the first terminal row part and the second terminal row part are close to the second electronic device 02, facilitating the connection between the first electronic device 01 and the second electronic device 02. The first connection row 1222 and the second connection row 1322 can also be used to transmit signals, so as to transfer the signals on the extension part 124 and the third sub-row 131 to the first terminal row part and the second terminal row part.

[0204] Similarly, the first connection row 1222 is perpendicular or intersects with the second extension part 1242, and the second connection row 1322 is perpendicular or intersects with the third sub-row 131. In this way, the positions and angles of the first terminal row part and the second terminal row part can be changed through the first connection row 1222 and the second connection row 1322, so as to adapt to different processing scenarios and usage scenarios.

[0205] In some embodiments, the first bus bar 12 and the second bus bar 13 form the output terminals of the body 11, or the first bus bar 12 and the second bus bar 13 form the input terminals of the body 11.

[0206] In this way, the first bus bar 12 and the second bus bar 13 can be used to transfer the signals processed by the first electronic device 01 to the second electronic device 02, and the first bus bar 12 and the second bus bar 13 can also be used to receive signals, so that the electronic device processes the signals.

[0207] In some embodiments, the first electronic device 01 further includes a seventh insulating member 18, and at least part of the seventh insulating member 18 is disposed between the second sub-row 122 and the fourth sub-row 132.

[0208] Since the second sub-row 122 is connected to the positive electrode of the body 11 and the fourth sub-row 132 is connected to the negative electrode of the body 11, disposing at least part of the seventh insulating member 18 between the second sub-row 122 and the fourth sub-row 132 can insulate and isolate the second sub-row 122 and the fourth sub-row 132, thereby preventing direct contact between the positive and negative electrodes from causing a short circuit and damaging the electronic device.

[0209] In some embodiments, the seventh insulating member 18 includes an insulating member body 181 and an isolation part 182. The isolation part 182 is connected to the insulating member body 181, and the dimension along the stacking direction of the first sub-row 121 and the third sub-row 131 is greater than the thickness of the first terminal row part 1221 and the second terminal row part 1321.

[0210] In this way, the second sub-row 122 and the fourth sub-row 132 can be fully isolated, preventing high-voltage creepage or arcing between the first terminal row part 1221 and the second terminal row part 1321.

[0211] In some embodiments, the isolation portion 182 is provided with a positioning protrusion 183 that protrudes from the isolation portion 182 along the direction from the fourth sub-row 132 to the body 11.

[0212] Since the fourth insulating member 05 overlaps on the first terminal 0101 of the first electronic device 01, one of the first terminal row portion 1221 and the second terminal row portion 1321 can form the first terminal 0101. Therefore, the positioning protrusion 183 can limit the position of the fourth insulating member 05, preventing the fourth insulating member 05 from being misaligned or displaced, which may cause high-voltage arcing due to poor isolation between the first connecting member 03 and the second connecting member 04, making the insulation more reliable.

[0213] In the description of the embodiments of the present application, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0214] The above are only the specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
