[0024] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0025] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0026] It should be understood that the terms "length", "width", "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0027] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0028] It should be noted that inductance and resistance are indispensable basic circuit elements in the electrical field, and are widely used in various electronic devices and circuit designs. Resistance is used to limit current, divide voltage or control signal amplitude, while inductance is used for energy storage, filtering and signal processing and other functions.

[0029] In the related art, the circuit design usually needs to independently set the inductance and resistance, which leads to a large number of elements on the circuit board, thereby occupying a large space. Especially in some miniaturized and high-density integrated electronic devices, such as smart phones, tablet computers, wearable devices, etc., the space on the circuit board is very limited, and the layout mode of traditional resistance and inductance elements has been difficult to meet the space demand of these devices. In these devices, not only complex functions need to be realized, but also to be completed in the smallest possible volume. This design challenge has led to the fact that the traditional layout mode of resistance and inductance elements has been difficult to meet the space demand of modern electronic devices. For example, the internal of a smart phone needs to contain a processor, memory, sensors and multiple communication modules, and the dispersion layout of various circuit elements such as resistance and inductance will occupy valuable space, limiting the configuration of other components. At the same time, with the increase of functions, the wiring density of the circuit board is also increasing, and the traditional discrete circuit elements not only increase the risk of mutual interference between elements, but also may cause signal delay and power consumption increase. Especially for wearable devices, the demand for light weight and miniaturization is imminent, which makes it particularly important to reduce the occupied space of resistance and inductance in the design, so as to achieve higher integration.

[0030] Therefore, the related electrical components and electronic devices are improved based on this.

[0031] Please refer to Figure 1 , Figure 1 The structure of the electrical component provided by the embodiment is shown. The electrical component of the embodiment includes an inductor 100 and a resistor 200; the inductor 100 includes a coil 110, the coil 110 has a first pin 111 for extending along a first direction b and being arranged, the first pin 111 is used for connecting a circuit board; the resistor 200 is arranged on the side of the inductor 100 away from the wire of the first pin 111, and the resistor 200 has a second pin 210, and the second pin 210 extends to the side of the inductor 100 where the first pin 111 is arranged along the first direction b, and the second pin 210 is used for connecting the circuit board.

[0032] It needs to be explained that the coil 110 is usually wound by a wire for realizing the storage and conversion of electric energy. The first pin 111 is usually used for the connection of other electrical elements on the circuit board. Generally speaking, the inductor 100 also includes a magnetic core, and the coil 110 is wound on the magnetic core. The main role of the magnetic core in the inductor is to enhance the magnetic field generated by the coil 110. The magnetic core has high magnetic permeability and can guide the magnetic field lines to pass through the coil 110 more concentratedly, thereby improving the inductance value. However, it should be noted that not all inductors need a magnetic core. In particular, in some applications where the inductance value is not high or the volume and weight need to be reduced, a hollow coil 110 may be used. The resistor 200 is an electrical element capable of limiting the flow of current. The second pin 210 extends to the first pin 111 along the first direction b, which means that the pins of the resistor 200 are adjacent to the pins of the inductor 100 in physical position, facilitating the layout and connection on the circuit board.

[0033] It can be understood that in the related art, the resistance and inductance are separately arranged, especially when the number of resistance and inductance is large, which will occupy a large space on the circuit board. However, the inductor 100 and the resistor 200 in the embodiment are arranged in an integrated structure, which solves the problem of separate arrangement of resistance and inductance elements in the traditional structure. This compact design not only reduces the number of overall elements and the occupied space, but also effectively reduces the mutual interference phenomenon in the circuit board and improves the transmission efficiency of the signal. In addition, the side-by-side arrangement of the elements also simplifies the wiring design of the circuit board, which helps to further reduce the product volume and meet the requirements of modern electronic equipment for miniaturization and high-density integration. That is, the resistor 200 can be arranged above the inductor 100, thereby reducing the space occupation on the surface of the circuit board.

[0034] In some embodiments of the present application, please continue to refer to Figure 1 The electrical assembly of the embodiment further includes a first fixing structure 300 arranged on at least one side of the inductor 100. The coil 110 is routed in the first fixing structure 300, and part of the first pin 111 is arranged in the first fixing structure.

[0035] It needs to be explained that the main function of the first fixing structure 300 is to fix and support the coil 110. The coil 110 is routed within the first fixing structure 300, which means that at least a part (possibly all or most) of the coil 110 is surrounded or supported by the first fixing structure 300. This structure helps to maintain the stability and shape of the coil 110, preventing it from moving or deforming during operation. At least part of the coil 110 passes through the first fixing structure 300 to form the first pin 111. This means that the first pin 111 is not separately attached to the coil 110, but is part of the coil 110 itself, which is extended out by passing through the first fixing structure 300 to form a pin for connecting to the circuit board. This design simplifies the manufacturing process of the inductor 100 and improves the electrical connection reliability between the pin and the coil 110.

[0036] In some embodiments of the present application, please refer to Figure 2 , Figure 2 The structure of the electrical assembly provided by the present embodiment is shown. The first fixing structure 300 of the present embodiment is provided with a first through hole 310, and the second pin 210 passes through the first through hole 310 and extends out of the first through hole 310 along the first direction b.

[0037] It needs to be explained that the main function of the first through hole 310 is to allow the second pin 210 to pass through. Since the second pin 210 needs to extend along the first direction b, the first through hole 310 provides a passage for the second pin 210 to pass through the first fixing structure 300 and extend to the outside. The second pin 210 passes through the first through hole 310. This means that a part (possibly all or most) of the second pin 210 is surrounded by the first through hole 310. This design helps to maintain the stability and positional accuracy of the second pin 210. The second pin 210 extends out of the first through hole 310 along the first direction b. This means that the second pin 210 not only passes through the first through hole 310, but also continues to extend along the first direction b in order to connect with other elements or circuits on the circuit board.

[0038] In some embodiments of the present application, please continue to refer to Figure 2 The first through hole 310 of the present embodiment is arranged along the first direction b.

[0039] It can be understood that since the first through hole 310 extends along the first direction b, the second pin 210 can easily pass through the through hole along this direction and extend to the outside. This design not only simplifies the process of the pin passing through the through hole, but also improves the flexibility and accuracy of the pin extension.

[0040] In some embodiments of the present application, please continue to refer to Figure 1The number of the first pins 111 is at least two, and the two first pins 111 are arranged side by side. At least one second pin 210 is arranged on the perpendicular line of the connecting line of the two adjacent first pins 111.

[0041] It can be understood that the at least two first pins 111 are usually arranged side by side along the same direction (i.e., the first direction b). This layout helps to maintain the compactness and orderliness of the electrical assembly, and facilitates the layout and connection on the circuit board. The second pin 210 is arranged between the at least two first pins 111. The arrangement of the second pin 210 between the at least two first pins 111 helps to save space on the circuit board and improve the integration of the circuit. At the same time, this layout also helps to reduce interference between elements and improve the stability of the circuit.

[0042] In some embodiments of the present application, please refer to Figure 1 and refer to Figure 3 , Figure 3 The structure of the electrical assembly provided by the present embodiment is shown in the structural schematic diagram; the number of the second pin 210 is at least two, and the at least two second pins 210 are arranged along the opposite sides of the inductor 100, respectively. The number of the first fixing structure 300 is at least two, and the at least two first fixing structures 300 are arranged on the opposite sides of the coil 110 to provide the outlet of the at least two second pins 210.

[0043] It needs to be explained that the at least two second pins 210 are arranged along the two sides of the inductor 100, which means that the pins of the resistor 200 are distributed on the two sides of the inductor 100, forming a symmetrical or dispersed layout. This layout helps to reduce interference between elements, improve the stability of the circuit, and facilitate wiring and connection on the circuit board. The number of the first fixing structure 300 is at least two, which helps to better fix and support the coil 110 and improve the stability and reliability of the inductor 100. The at least two first fixing structures 300 are arranged on the opposite sides of the coil 110, which means that they are distributed on the two sides of the coil 110, corresponding to the layout of the second pin 210. This layout not only helps to fix the coil 110, but also provides a channel and support for the outlet of the second pin 210.

[0044] In some embodiments of the present application, the coil 110 includes a first sub-coil and a second sub-coil, and the first sub-coil and the second sub-coil are arranged to outlet from the first fixing structure 300 on the two sides, respectively.

[0045] It can be understood that the first sub-coil and the second sub-coil can be a primary coil and a secondary coil, respectively.

[0046] In some embodiments of the present application, please refer to Figure 1The electrical assembly of the present embodiment further comprises a second fixing structure 400, wherein the coil 110 is disposed on the second fixing structure 400; the second fixing structure 400 is disposed between the at least two first fixing structures 300; and the second fixing structure 400 and the at least two first fixing structures 300 are integrated structures.

[0047] It can be understood that the coil 110 is disposed on the second fixing structure 400, which means that at least a part of the coil 110 is surrounded or supported by the second fixing structure 400. At the same time, the second fixing structure 400 is disposed between the at least two first fixing structures 300, and together with them forms a fixing and supporting system of the electrical assembly. Exemplarily, the second fixing structure 400 and the at least two first fixing structures 300 can be connected to form a "N" shaped structure, and the coil 110 is disposed in the groove of the "N" shaped structure to realize the fixation of the coil 110.

[0048] The second fixing structure 400 and the at least two first fixing structures 300 are integrated structures, which means that they are connected together by some means (such as injection molding, welding, bonding, etc.) to form a whole. This design helps to enhance the structural strength and stability of the electrical assembly, and at the same time simplifies the manufacturing process. By disposing the second fixing structure 400 between the at least two first fixing structures 300 and forming an integrated structure with them, the layout of the electrical assembly is more compact and orderly. This helps to reduce the size of the circuit board and improve the integration and efficiency of the circuit.

[0049] In some embodiments of the present application, please continue to refer to Figure 2 The at least one first fixing structure 300 in the present embodiment comprises a protruding portion 320, wherein the protruding portion 320 is disposed on the side of the first fixing structure 300 away from the coil 110, and the first through hole 310 is disposed in the protruding portion 320.

[0050] It needs to be explained that the protruding portion 320 can enhance the structural strength and stability of the first fixing structure 300, and the recessed structure on both sides of the protruding portion 320 can facilitate the arrangement of other electronic elements to save space. The protruding portion 320 is disposed on the side of the first fixing structure 300 away from the coil 110, which means that the protruding portion 320 is located at a relatively external position between the coil 110 and the first fixing structure 300. This design helps to ensure that the protruding portion 320 does not interfere with the normal work of the coil 110, while providing sufficient space to set the first through hole 310.

[0051] In some embodiments, the resistance 200 is a pressure sensitive resistance. The pressure sensitive resistance can be applied in the AC input loop of the power converter, and the pressure sensitive resistance is connected behind the fuse and in parallel between the live wire or the zero wire in the AC input loop, which is beneficial to absorb the instantaneous pulse voltage of the power grid, so as to improve the lightning strike resistance of the power converter.

[0052] In some embodiments, the inductor 100 is a common mode inductor. The varistor and the common mode inductor are both connected to an AC input circuit in a circuit application, and the inductor functions to reduce EMI interference of the power supply to the power grid.

[0053] Further, in order to better implement the electrical assembly in any of the above embodiments, based on the above electrical assembly, the application further provides an electronic device comprising the above electrical assembly.

[0054] In some embodiments, the electronic device can be a power converter.

[0055] In some embodiments, the electronic device can be other devices to which the power converter is applied.

[0056] In the above embodiments, the description of each embodiment focuses on different aspects, and the parts not described or recorded in detail in a certain embodiment can be referred to the related description of other embodiments.

[0057] The above has described the basic concepts, and it is obvious that the above detailed disclosure is only used as an example and does not limit the application. Although it is not explicitly stated here, those skilled in the art can make various modifications, improvements and corrections to the application. Such modifications, improvements and corrections are suggested in the application, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of the application.
