[0089] In the embodiments of the present application, the terms "first", "second", "third", "fourth", "fifth", and "sixth" are merely used for descriptive purposes, and should not be construed to refer to or imply relative importance or a specific number of the technical features indicated. Thus, the features defined with "first", "second", "third", "fourth", "fifth", and "sixth" can explicitly or implicitly include one or more of the features.

[0090] In the embodiments of the present application, the terms "comprising", "including", or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article, or apparatus including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such a process, method, article, or apparatus. Without more limitations, the element defined by the phrase "including a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus including the element.

[0091] "A and / or B" includes the following three combinations: only A, only B, and a combination of A and B.

[0092] In the embodiments of the present application, "parallel", "perpendicular", and "equal" include the stated case and a similar case to the stated case, the similar case being within an acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art considering the measurement being discussed and the error related to the measurement of a specific quantity (i.e., limitations of the measurement system). For example, "parallel" includes absolute parallel and approximate parallel, wherein the acceptable deviation range of approximate parallel can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicular and approximate perpendicular, wherein the acceptable deviation range of approximate perpendicular can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, a difference between the two equalities less than or equal to 5% of either one.

[0093] The embodiments of the present application can provide a power consuming device, which can include a mobile phone, a computer, a vehicle, a ship, a household appliance, a mechanical device, or an industrial device, etc. The embodiments of the present application are described in detail with the power consuming device being a vehicle.

[0094] It can be understood that the vehicle can be a fuel car, an electric car, a hybrid car, a gas car, a methanol car, a solar car, etc. The vehicle can be a passenger car such as a car, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), etc., or a passenger car, a cargo car, a semi-trailer, an engineering vehicle, etc. The present application does not make specific limitations.

[0095] Please refer to Figure 1 , Figure 1 A structural schematic diagram of a vehicle 1000 provided by an embodiment of the present application can include a chassis, a vehicle body, and a controller.

[0096] The chassis 100 can install a motor and other components of the vehicle 1000, form the overall shape of the vehicle 1000, and receive power from the motor to make the vehicle 1000 move and ensure normal driving.

[0097] The vehicle body 200 can be installed on the chassis 100, and the vehicle body 200 is internally formed with a vehicle cabin, and the vehicle cabin is provided with a seat for the driver, passengers to sit or load goods. It should be noted that when the vehicle 1000 is a passenger car or a car, the vehicle body 200 is generally a whole structure. When the vehicle 1000 is a truck, the vehicle body 200 is generally composed of a cab and a cargo box.

[0098] The controller 300 can be installed on the chassis 100, and the controller 300 is used to manage the stability and maneuverability of the vehicle 1000, including functions such as anti-slip control (TCS), electronic stability control (ESP), and all-wheel drive control (AWD). The controller 300 can also be responsible for engine fuel injection, ignition timing, speed and other parameters to optimize engine performance, improve fuel efficiency and reduce emissions. The controller 300 is one of the most critical parts of the vehicle 1000.

[0099] It should be noted that the above components are only examples of some components of the vehicle 1000, and are not specific limitations on the structure of the vehicle 1000.

[0100] The controller 300 can include electronic devices, and different electronic devices can perform corresponding functions. For example, the electronic device can be a direct current support capacitor, which can provide protection to the module, absorb ripples, and prevent the module from being punctured due to high voltage. For example, the electronic device can also be a power module, which functions to convert power output and provide power input to the motor.

[0101] Different electronic devices are connected by input terminals and output terminals in a one-to-one correspondence manner through nuts. Please refer to Figure 2 , Figure 2 Figure 1 is a schematic diagram of a structure of an electronic device in the related art. The output terminals 002 of the existing electronic device 001 are arranged side by side, and holes are formed in the output terminal part for nut connection.

[0102] In order to reserve the nut mounting position, the terminals of the electronic device need to be extended by a certain length to make the connection between different electronic devices more stable. However, the lengthening of the terminals will cause the inductance loop of the electronic device to increase, resulting in excess stray inductance.

[0103] In the circuit system of the controller 300, the inductance formed by accident or non-design expectation is called stray inductance (SI). Stray inductance is usually caused by the relative position between conductors, wiring layout, packaging design, or magnetic field in the surrounding environment. The existence of stray inductance will cause problems such as circuit system loss or signal attenuation, affecting the stability of transmission.

[0104] Based on this, please refer to Figure 3 , Figure 3 Figure 3 is a schematic diagram of a structure 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 connecting piece 03.

[0105] The first electronic device 01 includes a first electronic device body and a first terminal 0101 connected to the first electronic device body, and 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 arranged in a stacked manner. In this way, the structure of the controller 300 is more compact, and the connection loop of the first electronic device 01 and the second electronic device 02 can be shortened, thereby reducing stray inductance. In addition, the controller 300 can realize more functions in a limited space, which is suitable for the needs of miniaturized electronic products.

[0106] The first connecting piece 03 is connected between the first terminal 0101 and the second terminal 0201, and can electrically connect or transmit signals of the first electronic device 01. 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.

[0107] 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.

[0108] Please refer to Figure 4 , Figure 4A structure schematic diagram of an electronic device provided by an embodiment of the present application 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 together, and the second busbar 13 can include a third sub-busbar 131 and a fourth sub-busbar 132 connected together. At least part of the body 11 is arranged between the first sub-busbar 121 and the third sub-busbar 131, the second sub-busbar 122 and the fourth sub-busbar 132 are arranged in a stack, and the second sub-busbar 122 and the fourth sub-busbar 132 are both arranged on a side of the first sub-busbar 121 opposite to the third sub-busbar 131, or the second sub-busbar 122 and the fourth sub-busbar 132 are both arranged on a side of the third sub-busbar 131 opposite to the first sub-busbar 121.

[0109] One of the first busbar 12 and the second busbar 13 can be connected to a positive electrode of the body 11, and the other one of the first busbar 12 and the second busbar 13 can be connected to a negative electrode of the body 11, so that the first busbar 12 and the second busbar 13 can constitute a positive electrode input terminal or a negative electrode input terminal or a positive electrode output terminal or a negative electrode output terminal of the electronic device. Arranging at least part of the body 11 between the first sub-busbar 121 and the third sub-busbar 131 can increase a contact area of the body 11 with the first sub-busbar 121 and the third sub-busbar 131, and can improve a response speed of the electronic device.

[0110] Since the second sub-busbar 122 is connected to the first sub-busbar 121 and the fourth sub-busbar 132 is connected to the third sub-busbar 131, the first electronic device 01 can be connected to positive and negative electrode terminals of the second electronic device 02 through the second sub-busbar 122 and the fourth sub-busbar 132, respectively, to constitute an electrical connection.

[0111] Since the second electronic device 02 is arranged in a stack with the first electronic device 01, the second electronic device 02 can be located on a side of the first sub-busbar 121 opposite to the third sub-busbar 131, or on a side of the third sub-busbar 131 opposite to the first sub-busbar 121. Therefore, arranging the second sub-busbar 122 and the fourth sub-busbar 132 both on the side of the first sub-busbar 121 opposite to the third sub-busbar 131, or arranging the second sub-busbar 122 and the fourth sub-busbar 132 both on the side of the third sub-busbar 131 opposite to the first sub-busbar 121, can reduce a distance from the second sub-busbar 122 and the fourth sub-busbar 132 to the second electronic device 02, thereby shortening lengths of the second sub-busbar 122 and the fourth sub-busbar 132 and reducing generation of stray inductance in a transmission loop.

[0112] In addition, arranging the second sub-busbar 122 and the fourth sub-busbar 132 both on the side of the first sub-busbar 121 opposite to the third sub-busbar 131, or on the side of the third sub-busbar 131 opposite to the first sub-busbar 121, can reduce line redundancy from the first sub-busbar 121 to the second sub-busbar 122 and from the third sub-busbar 131 to the fourth sub-busbar 132, thereby also shortening lengths of the second sub-busbar 122 and the fourth sub-busbar 132 and reducing stray inductance in a loop.

[0113] The second sub-row 122 and the fourth sub-row 132 are arranged in layers, 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, so that the inductance directions of the current lines in the second sub-row 122 and the fourth sub-row 132 are opposite and can offset each other, 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.

[0114] Next, the application is specifically introduced by connecting the first bus bar 12 to the positive electrode of the body 11 and connecting the second bus bar 13 to the negative electrode of the body 11. It can be understood that the first bus bar 12 can also be connected to the negative electrode of the body 11, and the second bus bar 13 is connected to the positive electrode of the body 11, which will not be specifically illustrated here.

[0115] In some embodiments, the second sub-row 122 and the fourth sub-row 132 are arranged on the side of the first sub-row 121 opposite to the third sub-row 131, the second sub-row 122 is connected to the first sub-row 121, and the second bus bar 13 includes a transition row 133 connected between the third sub-row 131 and the fourth sub-row 132.

[0116] Since the second sub-row 122 and the fourth sub-row 132 are arranged on the side of the first sub-row 121 opposite to the third sub-row 131, the second sub-row 122 and the first sub-row 121 are located on the same side of the body 11, and the third sub-row 131 and the fourth sub-row 132 are located on opposite sides of the body 11.

[0117] Connecting the second sub-row 122 to the first sub-row 121 can shorten the length of the first bus bar 12, make the structure of the first bus bar 12 simpler, and save production costs. Arranging the 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.

[0118] In other embodiments, when the second electronic device 02 is arranged on the side of the third sub-row 131 opposite to the first sub-row 121, the second sub-row 122 and the fourth sub-row 132 can be arranged on the side of the third sub-row 131 opposite to the first sub-row 121, the fourth sub-row 132 is connected to the second sub-row 122, the first bus bar 12 includes a transition row 133 connected between the first sub-row 121 and the second sub-row 122.

[0119] In some embodiments, the transition row 133 can be arranged 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 peripheral surface of the body 11. Arranging the transition row 133 on the periphery of the body 11 can make the structure of the second bus bar 13 and the body 11 simple and easy to assemble.

[0120] In some other embodiments, an opening can be provided in the inner portion of the body 11, and the transition row 133 can be arranged in the body 11 to connect the third sub-row 131 and the fourth sub-row 132.

[0121] In some embodiments, the transition row 133 can include a first transition row 1331 arranged on the side of the body 11 and connected to the third sub-row 131, and a second transition row 1332 arranged on the side of the body 11 opposite to the third sub-row 131 and connected to the first transition row 1331; the fourth sub-row 132 is connected to the end of the second transition row 1332 away from the first transition row 1331.

[0122] The third sub-row 131 and the fourth sub-row 132 are connected in sequence through the first transition row 1331 and the second transition row 1332, the first transition row 1331 is arranged on the side of the body 11, and the second transition row 1332 is arranged on the side of the body 11 opposite to the third sub-row 131, that is, the second transition row 1332 and the fourth sub-row 132 can be arranged on the same side of the body 11, and the first transition row 1331 and the second transition row 1332 are connected, which can make the connection of the third sub-row 131 and the fourth sub-row 132 more stable.

[0123] Since the side of the body 11 where the first sub-row 121 is located is the positive electrode of the body 11, the side of the body 11 where the third sub-row 131 is located 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 side of the body 11, in some embodiments, the electronic device can further include a first insulating member arranged between at least part of the transition row 133 and the body 11. In this way, the first insulating member can insulate the transition row 133 from the body 11, prevent the transition row 133 from contacting the positive electrode surface of the body 11, and cause short circuit damage to the electronic device.

[0124] In some other embodiments, the transition row 133 can also be arranged spaced apart from the surface of the body 11, so that the surface of the body 11 is not in contact with the transition row 133, preventing short circuit damage to the electronic device.

[0125] In some embodiments, the first insulating member is arranged 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 arranged on the side of the body 11 opposite to the third sub-row 131, there is a risk of contact short circuit with the positive electrode of the body 11, therefore, the first insulating member arranged between the second transition row 1332 and the body 11 can prevent the second transition row 1332 from contacting the positive electrode of the body 11 and causing short circuit damage to the electronic device.

[0126] For example, the first insulation member can be a plastic film or a rubber sheet, or an insulating material can be poured between the second transition member and the body 11 to insulate the second transition row 1332 from the body 11.

[0127] Please continue to refer to Figure 4 In some embodiments, the first sub-row 121 includes a first portion 1211, a second portion 1212, and a third portion 1213, the second portion 1212 and the third portion 1213 are located on the same side of the first portion 1211 and connected to the first portion 1211, and the second portion 1212 is spaced apart from the third portion 1213. The second sub-row 122 is connected to the edge of the first portion 1211 between the second portion 1212 and the third portion 1213, and the second transition row 1332 is located between the second portion 1212 and the third portion 1213, one end of the second transition row 1332 away from the first portion 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 portion 1211.

[0128] The second portion 1212 and the third portion 1213 can increase the contact area of the first sub-row 121 with the body 11, reduce the risk of poor contact, and reduce current instability, signal loss, or noise due to poor contact. At the same time, the second portion 1212 and the third portion 1213 are spaced apart and located on one side of the first portion 1211, so that the first portion 1211, the second portion 1212, and the third portion 1213 can form an avoidance opening, and can leave an avoidance space for the second sub-row 122, the fourth sub-row 132, and the second transition row 1332, so that the layout of the first female row 12 and the second female row 13 is more reasonable.

[0129] In addition, the second sub-row 122 is connected to the edge of the first portion 1211 between the second portion 1212 and the third portion 1213, and the fourth sub-row 132 is connected to one end of the second transition row 1332 facing the first portion 1211, so that the second sub-row 122 and the fourth sub-row 132 can be arranged opposite to each other, which facilitates the stacking of the second sub-row 122 and the fourth sub-row 132 and reduces the stray inductance in the circuit.

[0130] It should be noted that the second portion 1212 and the third portion 1213 can also be an integral structure, the second portion 1212 and the third portion 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 portion 1212 and the third portion 1213 away from the body 11. This can further increase the contact area of the first sub-row 121 with the body 11.

[0131] 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 main body 11, the second transition row 1332 is spaced apart from the second part 1212 and the third part 1213 along the arrangement direction of the first sub-row 121 and the third sub-row 131 so as to insulate the second transition row 1332 from the second part 1212 and the third part 1213.

[0132] A first insulating member may be further provided between the second transition bar 1332 and the second portion 1212 and the third portion 1213 to further insulate the second transition bar 1332 from the second portion 1212 and the third portion 1213 to prevent a short circuit between the positive and negative electrodes.

[0133] Please refer to Figure 4 and Figure 5 , Figure 5 for Figure 4 The schematic diagram of the structure of the electronic device shown in FIG. 1 shows another angle. In some embodiments, the second sub-row 122 may include a first terminal block portion 1221, and the fourth sub-row 132 may include a second terminal block portion. Along the stacking direction of the first sub-row 121 and the third sub-row 131, the distance from the first terminal block portion to the first sub-row 121 is equal to the distance from the second terminal block portion to the first sub-row 121.

[0134] 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 part to the first sub-row 121 is equal to the distance from the second terminal row part to the first sub-row 121, so the first terminal row part and the second terminal row part can be set at the same plane height. When the second electronic device 02 is connected to the first terminal row part and the second terminal row part, the number of times of positioning in the height direction is reduced, making the connection more convenient.

[0135] In some embodiments, the first terminal block portion, the second terminal block portion, and the first sub-row 121 are all arranged in parallel. The first terminal block portion is arranged in parallel with the first sub-row 121, and the second terminal block portion is also arranged in parallel with the first sub-row 121. In this way, the contact area between the first terminal block portion, the second terminal block 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.

[0136] In some embodiments, the second sub-row 122 further comprises a first connecting row 1222 connected between the first terminal row portion and the first sub-row 121, and the first connecting row 1222 is perpendicular to or intersects with the first sub-row 121; and / or, the fourth sub-row 132 further comprises a second connecting row 1322 connected between the second terminal row portion and the second transition row 1332, and the second connecting row 1322 is perpendicular to or intersects with the second transition row 1332.

[0137] The first connecting row 1222 and the second connecting 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 of the first electronic device 01 and the second electronic device 02. The first connecting row 1222 and the second connecting row 1322 can also be used to transmit signals to transfer 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.

[0138] In addition, the first connecting row 1222 is perpendicular to or intersects with the first sub-row 121, and the second connecting row 1322 is perpendicular to or intersects with the second transition row 1332, so that the position and angle of the first terminal row portion and the second terminal row portion can be changed through the first connecting row 1222 and the second connecting row 1322, thereby adapting to different processing scenarios and use scenarios.

[0139] For example, the first connecting row 1222 is perpendicular to the first sub-row 121, and the second connecting row 1322 is perpendicular to the second transition row 1332, which can facilitate processing and improve processing efficiency.

[0140] Since the first terminal row portion and the second terminal row portion are parts of the first busbar 12 and the second busbar 13 respectively, the first terminal row portion and the second terminal row portion can constitute a positive terminal and a negative terminal of the electronic device. Since the electronic device can include input terminals and output terminals, in some embodiments, the electronic device can further comprise a first external terminal 14 and a second external terminal 15, which are located on the side of the second transition row 1332 opposite to the body 11 and are electrically connected to the body 11.

[0141] In this way, the first external terminal 14 and the second external terminal 15 can constitute one of the input terminals and the output terminals, and the first terminal row portion and the second terminal row portion can constitute the other of the input terminals and the output terminals, so that the electronic device can receive signals and transmit the signals to the next link.

[0142] The first external terminal 14 and the second external terminal 15 are located on the side of the second transition row 1332 opposite to the body 11, so that the first external terminal 14, the second external terminal 15, the second sub-row 122 and the fourth sub-row 132 are 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 with other components.

[0143] In some embodiments, the first busbar 12 and the second busbar 13 form output terminals of the body 11, and the first external terminal 14 and the second external terminal 15 form input terminals of the body 11.

[0144] In this way, the first busbar 12 and the second busbar 13 can be used to transmit the processed signal of 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 the signal so that the electronic device processes the signal.

[0145] In some other embodiments, the first busbar 12 and the second busbar 13 form input terminals of the body 11, and the first external terminal 14 and the second external terminal 15 form output terminals of the body 11.

[0146] Please refer to Figure 4~Figure 6 , Figure 6 For Figure 4 the electronic device shown in the structural schematic view from another angle, in some embodiments, the electronic device can further include a second insulating member 16, at least part of the second insulating member 16 is arranged between the second sub-row 122 and the fourth sub-row 132.

[0147] Since the second sub-row 122 is connected to the positive electrode of the body 11, the fourth sub-row 132 is connected to the negative electrode of the body 11, and at least part of the second insulating member 16 is arranged between the second sub-row 122 and the fourth sub-row 132, the second sub-row 122 and the fourth sub-row 132 can be insulated and isolated, so as to prevent the positive and negative electrodes from being directly contacted to cause short circuit and damage to the electronic device.

[0148] In some embodiments, the second insulating member 16 includes an insulating isolation portion 161, and the insulating isolation portion 161 is arranged between the first terminal row portion 1221 and the second terminal row portion 1321.

[0149] In this way, the second sub-row 122 and the fourth sub-row 132 can be fully isolated to prevent high-voltage arc between the first terminal row portion 1221 and the second terminal row portion 1321.

[0150] In some embodiments, the size 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.

[0151] In this way, the insulation isolation part 161 can extend from the first terminal row part 1221 and the second terminal row part 1321, sufficiently insulate the first terminal row part 1221 and the second terminal row part 1321, and further prevent high-voltage creeping and arc.

[0152] In some embodiments, the electronic device can further include a limiting part 162 located at opposite ends of the first terminal row part 1221 and / or the second terminal row part 1321 in 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 part 1221 and the second terminal row part 1321.

[0153] The limiting part 162 is arranged at the two ends of the first terminal row part 1221 and / or the second terminal row part 1321. Since the first connecting piece 03 is overlapped 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 constitute the first terminal 0101, and therefore, the limiting part 162 can limit the first connecting piece 03, preventing dislocation 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.

[0154] In some embodiments, the electronic device can further include a third insulation piece 17, at least part of the third insulation piece 17 being arranged between the first external terminal 14 and the second external terminal 15.

[0155] Since the first external terminal 14 and the second external terminal 15 constitute the positive and negative poles of a group of terminals of the electronic device respectively, arranging at least part of the third insulation piece 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 and causing short circuit, and damaging the electronic device.

[0156] In some embodiments, the first insulation piece, the second insulation piece 16, and the third insulation piece 17 can be an integral structure, which can reduce the connection gap between the insulation pieces, reduce the occurrence of electric leakage, high-voltage arc, and the like, and make the insulation isolation more sufficient.

[0157] For example, the first insulation piece, the second insulation piece 16, and the third insulation piece 17 can be formed by injection molding. After the body 11, the first busbar 12, and the second busbar 13 are connected, the body 11, the first busbar 12, and the second busbar 13 are placed in an injection mold, and an insulation material such as epoxy resin is added to the mold to form the first insulation piece, the second insulation piece 16, and the third insulation piece 17 in an integral structure.

[0158] In some embodiments, the first sub-bank 121 is provided with a first glue hole, the third sub-bank 131 is provided with a second glue hole, and the first glue hole, the second glue hole and the third glue hole are opposite and communicate with each other.

[0159] In this way, a flow channel can be provided for the insulating filler to flow into each gap, so that the insulation is more sufficient.

[0160] The material of the insulating filler can be epoxy resin, polyester resin or silica gel, and the present application does not make further limitation.

[0161] Please refer to Figure 3 、 Figure 7 and Figure 8 , Figure 7 the assembly diagram of the controller 300 shown in Figure 3 , Figure 8 the partial enlarged view of the controller 300 at A shown in Figure 7 , the controller 300 provided by the present application, the second electronic device body and the first electronic device body are arranged along a second direction, and the second terminal 0201 and the first terminal 0101 are arranged along a 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 electronic and the second electronic, it is not necessary to repeatedly position along the arrangement direction of the first electronic device body and the second electronic device body, and the connection is more convenient, and the connection efficiency is improved.

[0162] In addition, the first connecting piece 03 can be in the form of a planar sheet, and the first connecting piece 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 side by side, the first connecting piece 03 is arranged in the form of a planar sheet, so that the connecting device can be directly moved from above the first terminal 0101 to above the second terminal 0201, completing the connection of the first connecting piece 03 with the first terminal 0101 and the second electronic, and the connection operation is more simple, facilitating automatic production and processing.

[0163] Please refer to Figure 3~Figure 8 , wherein one of the first busbar 12 and the second busbar 13 of the electronic device provided in the above embodiments can constitute the first terminal 0101, and can be connected with the second electronic device 02 through the first connecting piece 03.

[0164] Please refer to Figure 8 and Figure 9 , Figure 9A structural schematic diagram of a first connecting piece 03 provided in an embodiment of the present application. In some embodiments, the first terminal 0101 and the first connecting piece 03, and the second terminal 0201 and the first connecting piece 03 can be connected by laser welding, which can reduce the terminal extension caused by nut connection, thereby shortening the connection loop of the electronic device and reducing the stray inductance caused by the increased loop. In addition, the nut connection may be loose during use, resulting in poor current capacity, causing the electronic device to produce arc or open circuit, causing unstable transmission. The first connecting piece 03 is laser welded with the first terminal 0101 and the second terminal 0201, which has good connection stability and accurate connection, thereby improving the stability of signal transmission between electronic devices.

[0165] In addition, the first terminal 0101 and the first connecting piece 03, and the second terminal 0201 and the first connecting piece 03 can be connected by ultrasonic welding, spot welding, etc. The present application does not limit this, and it is set according to the actual needs.

[0166] In some embodiments, the first connecting piece 03 includes a first connecting portion 031 and a second connecting portion 032 connected to each other, the first connecting portion 031 connects the first terminal 0101, the second connecting portion 032 connects the second terminal 0201, and 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 piece 03 is simple, and it is easy to manufacture and process.

[0167] In some embodiments, the first connecting portion 031 is welded with the first terminal 0101, and the second connecting portion 032 is welded with the second terminal 0201. In this way, the connection strength of the first connecting portion 031 and the first terminal 0101, and the connection strength of the second connecting portion 032 and the second terminal 0201 can be enhanced, preventing poor overcurrent capacity and circuit connection caused by unstable connection.

[0168] In addition, since the first connecting portion 031 and the first terminal 0101 can be laser welded, the second connecting portion 032 can be laser welded with the second terminal 0201, and the first connecting portion 031 and the second connecting portion 032 are arranged in the same plane, which can realize laser scanning of the first connecting piece 03 and the first terminal 0101 and the first connecting piece 03 and the second terminal 0201 at one time, thereby improving the welding efficiency. At the same time, it can avoid the risk of welding quality caused by switching welding due to the different distances from the laser source to the target surface to be welded.

[0169] In some embodiments, the first electronic device 01 can be provided with a first positioning portion, and the first connecting portion 031 is provided with a first positioning hole 0311 which can be connected with 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 misconnection or offset of the first connecting member 03 to cause poor welding.

[0170] In the electronic device provided by the above embodiments, the limiting portions 162 located at the opposite ends of the first terminal row portion 1221 along the first direction can constitute the first positioning portion, so as to limit the first connecting member 03 by cooperating with the first positioning hole 0311.

[0171] In some embodiments, the first connecting portion 031 can be provided in plurality, and the plurality of first connecting portions 031 are arranged at intervals along the first direction which is perpendicular to the arrangement direction of the first connecting portion 031 to the second connecting portion 032.

[0172] In this way, the deformation stress of the first connecting portion 031 caused by pressure during laser welding can be reduced, so that the first connecting portion 031 can form sufficient surface contact with the first terminal 0101, to avoid welding hole or false welding caused by insufficient contact of the first connecting portion 031 with the first terminal 0101.

[0173] It can be understood that the second connecting portion 032 can also be provided in plurality, and the plurality of second connecting portions 032 can be arranged at intervals along the first direction.

[0174] Please continue to refer to Figure 10 and Figure 11 , Figure 10 the further assembly view of the controller 300 shown in Figure 7 , Figure 11 the partial enlarged view of the controller 300 at B shown in Figure 10 In some embodiments, the first electronic device 01 can further include a third terminal 0102 connected to the first electronic device body, and the second electronic device 02 can 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 opposite to the second terminal 0201, and the fourth terminal 0202 is located on the side of the second terminal 0201 opposite to the first terminal 0101. The controller 300 further includes a second connecting member 04 connected between the third terminal 0102 and the fourth terminal 0202.

[0175] It can be understood that the first terminal 0101 can be a positive terminal of the first electronic device 01, and the third terminal 0102 can be a negative terminal of the first electronic device 01. In this way, since the first terminal 0101 is connected with the second terminal 0201, and the third terminal 0102 is connected with the fourth terminal 0202, the second terminal 0201 can be a positive terminal of the second electronic device 02, and the fourth terminal 0202 can be a negative terminal of the second electronic device 02. The first terminal 0101 and the second terminal 0201 can also be negative terminals, and the third terminal 0102 and the fourth terminal 0202 can be positive terminals.

[0176] The first terminal 0101 and the second terminal 0201 are taken as positive terminals, and the third terminal 0102 and the fourth terminal 0202 are taken as negative terminals in the present application. The first terminal 0101 and the second terminal 0201 as negative terminals, and the third terminal 0102 and the fourth terminal 0202 as positive terminals can be obtained by simple replacement, which will not be described here.

[0177] Since the first connecting piece 03 and the second connecting piece 04 are connected with the positive and negative terminals of the first electronic device 01 respectively, if the first connecting piece 03 and the second connecting piece 04 interfere with each other, a short circuit of the controller 300 will occur, which will cause damage to the controller 300.

[0178] The third terminal 0102 is arranged on the side of the first terminal 0101 opposite to the second terminal 0201, and the fourth terminal 0202 is arranged on the side of the second terminal 0201 opposite to the first terminal 0101, which can facilitate the arrangement of the first connecting piece 03 and the second connecting piece 04, prevent the first connecting piece 03 and the second connecting piece 04 from interfering due to the alternating arrangement of the third terminal 0102, the fourth terminal 0202 and the first terminal 0101, the second terminal 0201, and thus make the connection of the first electronic device 01 and the second electronic device 02 more convenient, and make the layout of the controller 300 more reasonable.

[0179] In some embodiments, the two ends of the second connecting piece 04 are connected with the third terminal 0102 and the fourth terminal 0202 respectively, and the middle part of the second connecting piece 04 is located on the side of the first connecting piece 03 opposite to the first terminal 0101 and the second terminal 0201.

[0180] In this way, the middle part of the second connecting piece 04 is located on the side of the first connecting piece 03 opposite to the first terminal 0101 and the second terminal 0201, which can prevent the first connecting piece 03 and the second connecting piece 04 from interfering, and can stably connect the third terminal 0102 and the fourth terminal 0202, and ensure the normal transmission of signals.

[0181] Please refer to Figure 10~Figure 12 , Figure 12A structure diagram of a second connecting piece 04 provided in an embodiment of the present application is shown in FIG. 4. In some embodiments, the second connecting piece 04 can include a third connecting portion 041 connected to the third terminal 0102, a fourth connecting portion 042 connected to the fourth terminal 0202, and a fifth connecting portion 043 connected between the third connecting portion 041 and the fourth connecting portion 042. The fifth connecting portion 043 is arranged along the second direction away from the first connecting piece 03.

[0182] In this way, the fifth connecting portion 043 can be used to connect the third connecting portion 041 and the fourth connecting portion 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 connecting piece 03 and the second connecting piece 04 are opposite, the fifth connecting portion 043 and the first connecting piece 03 are arranged along the second direction, which can reduce the stray inductance in the circuit. In addition, since the first connecting piece 03 and the second connecting piece 04 are connected to the positive terminal and the negative terminal respectively, the fifth connecting portion 043 and the first connecting piece 03 are arranged away from each other, which can insulate the first connecting piece 03 and the second connecting piece 04, thereby preventing the circuit of the controller 300 from short circuiting.

[0183] In some embodiments, the third connecting portion 041 is welded to the third terminal 0102, and the fourth connecting portion 042 is welded to the fourth terminal 0202. In this way, the connection strength of the third connecting portion 041 and the third terminal 0102, and the connection strength of the fourth connecting portion 042 and the fourth terminal 0202 can be enhanced, thereby preventing poor overcurrent capacity and circuit disconnection caused by unstable connection.

[0184] In some embodiments, the second electronic device 02 is provided with a second positioning portion, and the fifth connecting portion 043 is provided with a second positioning hole 0431 connected to the second positioning portion. In this way, the second positioning portion can limit the second connecting piece 04, thereby preventing misconnection or offset of the second connecting piece 04 and causing poor welding.

[0185] In other embodiments, the limiting portions 162 located at opposite ends of the second terminal row portion 1321 along the first direction in the first electronic device 01 can also constitute the second positioning portion, and the second positioning hole 0431 is arranged on the third connecting portion 041 to limit the second connecting piece 04 by cooperating with the second positioning hole 0431 and the limiting portions 162.

[0186] In some embodiments, the number of the third connecting portion 041 is multiple, and the multiple third connecting portions 041 are arranged away from each other along the first direction, which is perpendicular to the arrangement direction of the third connecting portion 041 to the fourth connecting portion 042.

[0187] In this way, the deformation stress of the fourth connecting portion 042 caused by pressure during laser welding can be reduced, so that the fourth connecting portion 042 can form a full surface contact with the third terminal 0102 to avoid welding blowholes or false welding caused by insufficient contact between the third connecting portion 041 and the third terminal 0102.

[0188] It can be understood that the fourth connecting portion 042 can also be provided in multiple numbers, and the multiple fourth connecting portions 042 can be arranged at intervals in the first direction.

[0189] Please refer to Figure 10 In some embodiments, the controller 300 can further include a fourth insulating member 05 arranged between the first connecting member 03 and the second connecting member 04. Since the first connecting member 03 and the second connecting member 04 are connected to the positive terminal and the negative terminal respectively, arranging the fourth insulating member 05 between the first connecting member 03 and the second connecting member 04 can further insulate the first connecting member 03 and the second connecting member 04, preventing high-voltage arc caused by poor insulation of the first connecting member 03 and the second connecting member 04.

[0190] Please refer to Figure 10 , Figure 11 and Figure 13 , Figure 13 A structure schematic diagram of a second electronic device 02 provided by the embodiments of the present application, in some embodiments, the second terminal 0201 and the fourth terminal 0202 are arranged at intervals in the second direction, and at least part of the second terminal 0201 is arranged in a stack with the fourth terminal 0202.

[0191] The second terminal 0201 and the fourth terminal 0202 are arranged at intervals, which can insulate the second terminal 0201 and the fourth terminal 0202 to prevent short circuit in the controller 300. The second terminal 0201 and the fourth terminal 0202 are arranged in a stack, and since the current directions in the second terminal 0201 and the fourth terminal 0202 are opposite, the directions of the magnetic fields generated thereby are opposite, so as to offset each other and reduce the stray inductance of the controller 300.

[0192] In addition, in some embodiments, the second terminal 0201 and the fourth terminal 0202 can be arranged at intervals in the arrangement direction of the first connecting portion 031 to the second connecting portion 032, so as to shorten the interval distance between the second terminal 0201 and the fourth terminal 0202.

[0193] In other embodiments, the ends of the second terminal 0201 and the fourth terminal 0202 can also extend in opposite directions, i.e., the second terminal 0201 and the fourth terminal 0202 are not arranged in a stack, which is not limited in the present application and can be arranged as required according to actual conditions. In other embodiments, the ends of the second terminal 0201 and the fourth terminal 0202 can also extend in opposite directions, i.e., the second terminal 0201 and the fourth terminal 0202 are not arranged in a stack, which is not limited in the present application and can be arranged as required according to actual conditions.

[0194] In some embodiments, the second electronic device 02 further comprises a fifth insulating member 021, which is arranged between the second terminal 0201 and the fourth terminal 0202.

[0195] In this way, the second terminal 0201 and the fourth terminal 0202 can be sufficiently insulated, so that the relative distance between the second terminal 0201 and the fourth terminal 0202 can be as small as possible, the connection loop can be shortened, and the stray inductance can be reduced.

[0196] Please refer to Figure 3 , Figure 7 and Figure 10 In some embodiments, the controller 300 can further comprise a heat dissipation member 06, the first electronic device body, the heat dissipation member 06 and the second electronic device body are arranged along a second direction, and the heat dissipation member 06 is arranged between the first electronic device body and the second electronic device body.

[0197] In this way, the heat dissipation member 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 working temperature of the first electronic device body and the second electronic device body.

[0198] For example, the heat dissipation member 06 can comprise a heat dissipation plate, and a water cooling channel is arranged in the heat dissipation plate. Through the water circulation in the heat dissipation plate, the cooling liquid in the water cooling channel can exchange heat with the first electronic device body and the second electronic device body, so as to realize the cooling of the controller 300.

[0199] Arranging the first electronic device body, the heat dissipation member 06 and the second electronic device body along the second direction can increase the contact area of the heat dissipation member 06 with the first electronic device body and the second electronic device body, improve the heat conduction performance, and improve the heat dissipation efficiency.

[0200] Please refer to Figure 10 , Figure 11 and Figure 14 and Figure 15 , Figure 14 a structural schematic view of a base 07 provided by the embodiments of the present application, Figure 15 is Figure 14 a structural schematic view of the base 07 from another angle, in some embodiments, the controller 300 can further comprise a base 07, the base 07 is provided with a first surface 071 and a second surface 072 opposite to each other, at least part of the first electronic device 01 is arranged on the first surface 071, and the second electronic device 02 is arranged on the second surface 072. The base 07 is further provided with a connecting opening 073 communicating the first surface 071 and the second surface 072, and the first terminal 0101 and the third terminal 0102 are connected with the second electronic device 02 through the connecting opening 073.

[0201] 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 integrating more functions in a limited space.

[0202] The base 07 is provided with an opening communicating the first surface 071 and the second surface 072, which can facilitate the connection of the first electronic device 01 and the second electronic device 02, without the need to connect the connecting terminals around the edge of the base 07, and the space layout is more reasonable. 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 connecting opening 073, which can shorten the length of the first terminal 0101 and the second terminal 0201, thereby reducing the stray inductance in the loop.

[0203] In some embodiments, the base 07 includes a mounting groove 074 protruding toward the second surface 072, at least part of the first electronic device 01 is arranged in the mounting groove 074, and the second electronic device 02 is arranged on the side of the mounting groove 074 away from the first electronic device 01.

[0204] In this way, arranging at least part of the first electronic device 01 in the mounting groove 074 can facilitate the positioning and installation of the first electronic device 01, making the structure of the controller 300 more accurate and the reliability better.

[0205] In some embodiments, the connecting opening 073 can be arranged on the wall surface between the first electronic device 01 and the second electronic device 02.

[0206] Since the second sub-row 122 and the fourth sub-row 132 of the first electronic device 01 can be arranged on the side of the first sub-row 121 away from the third sub-row 131, arranging the connecting opening 073 on the wall surface between the first electronic device 01 and the second electronic device 02 can make the first sub-row 121 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 out of the wall surface through the connecting opening 073 to connect with the second electronic device 02. In this way, the length of the second sub-row 122 and the fourth sub-row 132 can be shortened, the stray inductance in the loop can be reduced, and the stability and reliability of the controller 300 can be improved.

[0207] In other embodiments, the arrangement direction 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, and therefore, the connecting opening 073 can also be arranged on the base 07, and the arrangement direction of the mounting groove 074 and the connecting opening 073 intersects with the arrangement direction 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 to the side of the base 07 located on the second electronic device 02 through the connecting opening 073, facilitating the connection of the first electronic device 01 and the second electronic device 02.

[0208] In some embodiments, the material of the base 07 can be metal. Since metal has better thermal conductivity than plastic and other materials, 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 accumulation of heat in the controller 300 and causing performance degradation.

[0209] In some embodiments, the base 07 is provided with a cooling water channel 075, at least part of which is arranged between the bottom wall of the mounting groove 074 and the second surface 072. In this way, cooling liquid can be injected into the cooling water channel 075 to exchange heat with 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.

[0210] In some embodiments, a sixth insulating member is arranged 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 and the base 07 from conducting electricity, causing the controller 300 to leak electricity or signal transmission failure.

[0211] For example, 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.

[0212] In some embodiments, the mounting groove 074 can also be provided with a packaging material filled between the first electronic device 01 and the inner wall of the mounting groove 074. The packaging material can package the first electronic device 01, provide additional mechanical support for the first electronic device 01, effectively fix the first electronic device 01, reduce the impact of vibration and impact, and enhance the overall stability. The packaging material can also protect the first electronic device 01 from damage caused by dust, moisture and other external pollutants, and enhance the environmental resistance of the first electronic device 01.

[0213] In addition, the packaging material can also insulate the first electronic device 01 from the base 07, preventing the controller 300 from leaking or short-circuiting.

[0214] For example, the packaging material can be epoxy resin, silica gel or polyester resin, etc., which is not limited in the present application.

[0215] Please refer to Figure 4 、 Figure 16 and Figure 17 , Figure 16 for another structure of the first electronic device 01 provided by the embodiments of the present application, Figure 17 for the first electronic device 01 shown in Figure 16 applied to the partial structure of the controller 300, the embodiments of the present application also provide another first electronic device 01, which can also 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, and the second busbar 13 can include a third sub-busbar 131 and a fourth sub-busbar 132 connected to each other.

[0216] Among them, the body 11 is arranged between the first sub-busbar 121 and the third sub-busbar 131, and the positive electrode of the body 11 is connected with the first sub-busbar 121, and the negative electrode of the body 11 is connected with the third sub-busbar 131, or the negative electrode of the body 11 is connected with the first sub-busbar 121, and the positive electrode of the body 11 is connected with the third sub-busbar 131.

[0217] The fourth sub-busbar 132 and the second sub-busbar 122 are stacked, and the arrangement direction of the second sub-busbar 122 and the fourth sub-busbar 132 intersects with the arrangement direction 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 the first terminal 0101.

[0218] The fourth sub-busbar 132 and the second sub-busbar 122 are stacked, and the inductance direction of the current circuit in the second sub-busbar 122 and the fourth sub-busbar 132 is opposite, which offsets each other, reduces the stray inductance generated in the loop, and further improves the transmission stability of the first electronic device 01.

[0219] In addition, the second sub-row 122 and the fourth sub-row 132 are arranged on the outside of the main 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 current instability, signal loss or noise caused by poor contact.

[0220] In some embodiments, the first sub-row 121 includes a connecting portion 123 and an extending portion 124 . The connecting portion 123 is connected to the positive electrode of the body 11 , and the extending portion 124 is connected between the connecting portion 123 and the second sub-row 122 .

[0221] The extension portion 124 is used to connect the connection portion 123 and the second sub-row 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-row 122 in sequence. The extension portion 124 can facilitate signal transmission.

[0222] 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 peripheral 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 parallel to the third sub-row 131.

[0223] The first extension portion 1241 is located on the circumference of the body 11 and can extend the first sub-row 121 toward the third sub-row 131. Thus, when the first electronic device 01 is installed in the mounting groove 074, the second sub-row 122 and the fourth sub-row 132 can both extend out of the connection opening 073 and connect to the second electronic device 02. This simplifies the layout of the controller 300.

[0224] In addition, the second extension portion 1242 is connected to the first extension portion 1241 and is arranged parallel to the third sub-row 131 , so that the second sub-row 122 and the first extension portion 1241 are spaced apart to prevent signal interference or short circuit between the second sub-row 122 and the first extension portion 1241 .

[0225] In some embodiments, the second sub-row 122 includes a first terminal block portion 1221, and the fourth sub-row 132 includes a second terminal block portion. Along the stacking direction of the first and third sub-rows 121 and 131, the distance from the first terminal block portion to the first sub-row 121 is greater than the distance from the second terminal block portion to the first sub-row 121. In this way, the distances from the first and second terminal block portions to the first sub-row 121 are inconsistent, facilitating their stacking. This makes it easier to connect the first and second terminal block portions to the second electronic device 02, thereby reducing stray inductance.

[0226] In some embodiments, the first terminal row portion and the second terminal row portion are arranged in a stacked manner.

[0227] The first terminal row portion and the second terminal row portion are arranged in a stacked manner, and the inductances generated by the current lines in the first terminal row portion and the second terminal row portion are opposite in direction, which can be offset to each other, 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.

[0228] In some embodiments, the second sub-row 122 further comprises a first connecting row 1222 connected between the first terminal row portion and the extension 124, and the first connecting row 1222 is perpendicular to or intersects the first sub-row 121; and / or, the fourth sub-row 132 further comprises a second connecting row 1322 connected between the second terminal row portion and the third sub-row 131, and the second connecting row 1322 is perpendicular to or intersects the third sub-row 131.

[0229] The first connecting row 1222 and the second connecting 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 of the first electronic device 01 and the second electronic device 02. The first connecting row 1222 and the second connecting row 1322 can also be used to transmit signals to transfer signals on the extension 124 and the third sub-row 131 to the first terminal row portion and the second terminal row portion.

[0230] Similarly, the first connecting row 1222 is perpendicular to or intersects the second extension 1242, and the second connecting row 1322 is perpendicular to or intersects the third sub-row 131, so that the position and angle of the first terminal row portion and the second terminal row portion can be changed through the first connecting row 1222 and the second connecting row 1322, thereby adapting to different processing scenes and use scenes.

[0231] In some embodiments, the first busbar 12 and the second busbar 13 form output terminals of the body 11, or the first busbar 12 and the second busbar 13 form input terminals of the body 11.

[0232] In this way, the first busbar 12 and the second busbar 13 can be used to transmit the processed signals of the first electronic device 01 to the second electronic device 02, and the first busbar 12 and the second busbar 13 can also be used to receive signals to process the signals by the electronic device.

[0233] In some embodiments, the first electronic device 01 further comprises a seventh insulating member 18, at least part of the seventh insulating member 18 is arranged between the second sub-row 122 and the fourth sub-row 132.

[0234] Since the second sub-row 122 is connected to the positive electrode of the body 11, the fourth sub-row 132 is connected to the negative electrode of the body 11, and at least part of the seventh insulating member 18 is arranged between the second sub-row 122 and the fourth sub-row 132, the second sub-row 122 and the fourth sub-row 132 can be insulated and separated, so that direct contact of the positive electrode and the negative electrode to cause short circuit can be prevented, and the electronic device can be damaged.

[0235] In some embodiments, the seventh insulating member 18 includes an insulating member body 181 and a separation part 182, the separation part 182 is connected to the insulating member body 181, and the dimension of the separation part 182 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.

[0236] In this way, the second sub-row 122 and the fourth sub-row 132 can be fully separated, and high-voltage creeping or arc discharge between the first terminal row part 1221 and the second terminal row part 1321 can be prevented.

[0237] In some embodiments, the separation part 182 is provided with a positioning protrusion 183, and the positioning protrusion 183 protrudes from the separation part 182 in the direction from the fourth sub-row 132 to the body 11.

[0238] Since the fourth insulating member 05 is overlapped 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 constitute the first terminal 0101, and therefore, the positioning protrusion 183 can limit the fourth insulating member 05, prevent the fourth insulating member 05 from being dislocated or deviated to cause high-voltage arc discharge of the first connecting member 03 and the second connecting member 04 due to poor isolation, and make the insulation more reliable.

[0239] In the description of the embodiments of the present application, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0240] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
