Description

Technical Field

[0001] This application relates to the field of circuit board technology, and in particular to a circuit board and electronic device. Background Technology

[0002] Circuit boards are indispensable components in electronic devices, used to control the flow of current, its magnitude, and voltage. For electronic devices that perform similar functions, the required circuit boards often share the same functionality; that is, the types, quantities, and connections of the electronic components on the board are identical. However, for different models of electronic devices that perform the same function, their shapes and structures may differ, resulting in variations in the available space and shape for the circuit boards. This often necessitates the development and manufacturing of custom circuit boards for different electronic device models, leading to high costs. Utility Model Content The main technical problem solved by the embodiments of this application is to provide a circuit board and an electronic device. By setting a connecting plate between a first circuit board and a second circuit board, a removable connection between the first circuit board and the second circuit board is realized. Thus, for different models of electronic devices, it is possible to choose to keep the first circuit board and the second circuit board connected by the connecting plate, or to choose to separate the first circuit board and the second circuit board, so that the circuit board can be adapted to the requirements of various models of electronic devices, which helps to reduce the cost of the circuit board.

[0003] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a circuit board, including a first circuit board, a connecting plate, and a second circuit board. One end of the connecting plate is connected to the first circuit board, and one end of the second circuit board is connected to the end of the connecting plate opposite to the first circuit board. The first circuit board and the second circuit board are removably connected through the connecting plate. When the first circuit board and the second circuit board are connected through the connecting plate, the first circuit board and the second circuit board are electrically connected through the connecting plate. When the first circuit board and the second circuit board are separated, the circuit board also includes a wire, one end of which is electrically connected to the first circuit board, and the other end of which is electrically connected to the second circuit board. In this embodiment, the first circuit board and the second circuit board are removably connected by a connecting plate. When the internal space of the electronic device is sufficient to accommodate the first circuit board, the connecting plate, and the second circuit board connected as one unit, they can be directly installed inside the electronic device. When the internal space of the electronic device cannot accommodate the first circuit board, the connecting plate, and the second circuit board connected as one unit, the first circuit board and the second circuit board can be cut at the connecting plate to separate them. The separated first circuit board and the second circuit board are electrically connected by wires, so that the first circuit board and the second circuit board can be installed in different positions of the electronic device. This allows the circuit board to be used in various models of electronic devices without the need to design corresponding circuit boards for different models of electronic devices. It also reduces the number of production lines for producing circuit boards, which helps to save costs.

[0004] In some embodiments, the connecting plate is provided with a first material reduction hole, which is located between the first circuit board and the second circuit board. In this embodiment, by providing the first material reduction hole, when the connecting plate is cut with a tool or other cutting equipment, it can be cut along the center of the first material reduction hole, which helps to reduce the force required for cutting and facilitates the cutting of the connecting plate; in addition, the first material reduction hole can reduce the material of the connecting plate and reduce costs.

[0005] In some embodiments, there are multiple first material reduction holes, which are spaced apart along the length of the connecting plate, and the length of the connecting plate is perpendicular to the direction of the second circuit board toward the first circuit board. In this embodiment, by providing multiple first material reduction holes, when cutting the connecting plate, cutting can be performed along the center of the multiple first material reduction holes, which helps to further reduce the force required for cutting, reduce the cutting difficulty, and further reduce the material of the connecting plate, thereby reducing costs.

[0006] In some embodiments, the first material reduction hole is located at one end of the connecting plate near the first circuit board. This arrangement reduces the amount of connecting plate remaining on the first circuit board after the connecting plate is cut along the center of the first material reduction hole, thus reducing the space required to install the first circuit board and minimizing space waste.

[0007] In some embodiments, the connecting plate is provided with a second material reduction hole. Along the width direction of the connecting plate, the second material reduction hole and the first material reduction hole are spaced apart. The width direction of the connecting plate is the direction from which the second circuit board faces the first circuit board. In this embodiment, by providing a second material reduction hole, and with the first and second material reduction holes spaced apart along the width direction of the connecting plate, when cutting the connecting plate, it is possible to first cut along the center of the first material reduction hole, and then cut along the center of the second material reduction hole. This reduces the amount of connecting plate residue on the second circuit board, thereby reducing the space occupied by the cut second circuit board, reducing the space required to install the second circuit board in the electronic device, and reducing space waste.

[0008] In some embodiments, the second material reduction hole is located at one end of the connecting plate near the second circuit board. This arrangement reduces the amount of connecting plate remaining on the second circuit board after the connecting plate is cut along the center of the second material reduction hole, thus reducing the space required to install the second circuit board and minimizing space waste.

[0009] In some embodiments, there are multiple second material reduction holes, which are arranged along the length of the connecting plate. In this embodiment, by providing multiple second material reduction holes, the connecting plate can be cut along the center of the multiple second material reduction holes, which helps to further reduce the force required for cutting, reduce the cutting difficulty, and further reduce the material of the connecting plate, thereby reducing costs.

[0010] In some embodiments, when the first circuit board is separated from the second circuit board, the first circuit board is provided with a first connection portion, and one end of a wire is electrically connected to the first connection portion.

[0011] In some embodiments, when the first circuit board is separated from the second circuit board, the second circuit board is provided with a second connection portion, and one end of the wire away from the first circuit board is electrically connected to the second connection portion.

[0012] To solve the above-mentioned technical problems, another technical solution adopted in the embodiments of this application is: to provide an electronic device, including a housing and the above-mentioned circuit board, wherein the circuit board is mounted on the housing.

[0013] The beneficial effects of this application embodiment are as follows: Unlike the prior art, in this application embodiment, the first circuit board and the second circuit board are removably connected by a connecting plate. When the internal space of the electronic device is sufficient to simultaneously accommodate the first circuit board, the connecting plate, and the second circuit board connected as one unit, the first circuit board, the connecting plate, and the second circuit board connected as one unit can be directly installed inside the electronic device. When the internal space of the electronic device cannot simultaneously accommodate the first circuit board, the connecting plate, and the second circuit board connected as one unit, the first circuit board and the second circuit board can be cut at the connecting plate to separate the first circuit board and the second circuit board. The separated first circuit board and the second circuit board are electrically connected by wires, so that the first circuit board and the second circuit board can be installed in different positions of the electronic device, making the circuit board suitable for various models of electronic devices. It is not necessary to design corresponding circuit boards according to different models of electronic devices, and it can reduce the production line used to produce circuit boards, which is beneficial to saving costs.

It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

[0017] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application.

[0018] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0019] Circuit boards are used to control the on / off state of current, the magnitude of current, and the level of voltage, and are indispensable components in electronic devices. For electronic devices that perform similar functions, the required circuit boards often have the same function; that is, the types, quantities, and connections of the electronic components on the circuit board are the same.

[0020] However, for electronic devices that perform the same function but are of different models, their shapes and structures may differ, resulting in variations in the size and shape of the available space for mounting circuit boards. In related technologies, it is typically necessary to develop corresponding circuit boards for different models of electronic devices. On the one hand, designers need to design multiple circuit boards, which is time-consuming, labor-intensive, and has high manpower costs. On the other hand, different production lines are required for different circuit boards, leading to high equipment costs and the need for production line debugging, further increasing the overall cost of the circuit boards.

[0021] To at least partially solve the above problems, this application provides a circuit board and an electronic device. By providing a connecting plate between a first circuit board and a second circuit board, a removable connection between the first circuit board and the second circuit board is achieved. Thus, for different models of electronic devices, it is possible to choose to keep the first circuit board and the second circuit board connected by the connecting plate, or to choose to separate the first circuit board and the second circuit board, so that the circuit board can be adapted to the requirements of various models of electronic devices, which helps to reduce the cost of the circuit board.

[0022] The technical solution provided in this application is described below.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The circuit board 100 includes a first circuit board 1, a second circuit board 2, and a connecting plate 3. The connecting plate 3 is located between the first circuit board 1 and the second circuit board 2. One end of the connecting plate 3 is connected to the first circuit board 1, and the other end of the connecting plate 3 is connected to the second circuit board 2. The first circuit board 1 and the second circuit board 2 are removably connected via the connecting plate 3. That is, the first circuit board 1 and the second circuit board 2 can be held together by the connecting plate 3, or the first circuit board 1 and the second circuit board 2 can be cut off at the connecting plate 3, thereby separating the second circuit board 2 from the first circuit board 1. When the first circuit board 1 and the second circuit board 2 are connected via the connecting plate 3, they are electrically connected. At this time, the first circuit board 1, the connecting plate 3, and the second circuit board 2 are integrated into one unit. When assembling the circuit board 100 into the electronic device 1000, only one of the first circuit board 1 and the second circuit board 2 needs to be fixed to the electronic device 1000, making installation simple and convenient. When the first circuit board 1 and the second circuit board 2 are separated, the circuit board 100 also includes a wire 4. One end of the wire 4 is electrically connected to the first circuit board 1, and the other end of the wire 4 is electrically connected to the second circuit board 2. In this embodiment, the first circuit board 1 and the second circuit board 2 are removably connected via a connecting plate 3. When the internal space of the electronic device 1000 is sufficient to simultaneously accommodate the first circuit board 1, the connecting plate 3, and the second circuit board 2 connected as a single unit, the first circuit board 1, the connecting plate 3, and the second circuit board 2 connected as a single unit can be directly installed inside the electronic device 1000. Please refer to... Figure 4 and Figure 5 , Figure 4The diagram illustrates the structure of the electronic device 1000 when it is impossible to install the first circuit board, connecting board, and second circuit board that are connected as one unit. When the internal space of the electronic device 1000 cannot simultaneously accommodate the first circuit board 1, connecting board 3, and second circuit board 2 that are connected as one unit, the first circuit board 1 and the second circuit board 2 can be cut at the connecting board 3 to separate the first circuit board 1 and the second circuit board 2. The separated first circuit board 1 and the second circuit board 2 are electrically connected through wires 4, so that the first circuit board 1 and the second circuit board 2 can be installed in different positions of the electronic device 1000 respectively. This allows the circuit board 100 to be applicable to various models of electronic devices 1000 without the need to design corresponding circuit boards 100 for different models of electronic devices 1000, and it can reduce the number of production lines used to produce the circuit board 100, which is beneficial for saving costs.

[0024] It is worth noting that the connecting board 3 has an inner copper foil circuit (not shown in the figure). When the first circuit board 1, the connecting board 3 and the second circuit board 2 are connected as one unit, the first circuit board 1 and the second circuit board 2 are electrically connected through the inner copper foil circuit of the connecting board 3.

[0025] In some embodiments, the connecting plate 3 can be cut off from the position between the first circuit board 1 and the second circuit board 2 using a knife or other cutting equipment, thereby separating the first circuit board 1 and the second circuit board 2. It is worth noting that no electronic components are disposed on the connecting plate 3, therefore, cutting off the connecting plate 3 can reduce the impact on the operation of the circuit board 100.

[0026] In some embodiments, the connecting plate 3 is provided with a first material reduction hole 31, which is located between the first circuit board 1 and the second circuit board 2. In this embodiment, by providing the first material reduction hole 31, when the connecting plate 3 is cut using a knife or other cutting equipment, it can be cut along the center of the first material reduction hole 31, which helps to reduce the force required for cutting and facilitates the cutting of the connecting plate 3; in addition, the first material reduction hole 31 can reduce the material of the connecting plate 3 and reduce costs.

[0027] In some embodiments, the number of first material reduction holes 31 is multiple, and the multiple first material reduction holes 31 are distributed at intervals along the length direction X of the connecting plate 3, wherein the length direction X of the connecting plate 3 is perpendicular to the direction pointing to the second circuit board 2. In this embodiment, by providing multiple first material reduction holes 31, when cutting the connecting plate 3, cutting can be performed along the center of the multiple first material reduction holes 31, which helps to further reduce the force required for cutting, reduce the cutting difficulty, and further reduce the material of the connecting plate 3, thereby reducing costs.

[0028] It is worth noting that if the first material reduction hole 31 is located in the middle of the connecting plate 3 along the width direction Y of the connecting plate 3, then after cutting along the center of the first material reduction hole 31, part of the connecting plate 3 will remain on the first circuit board 1. This results in a large space occupied by the first circuit board 1, requiring the electronic device 1000 to reserve a large space for installing the first circuit board 1, which easily leads to space waste. Here, the width direction Y of the connecting plate 3 is the direction from the second circuit board 2 towards the first circuit board 1.

[0029] To at least partially solve the above problems, in some embodiments, the first material reduction hole 31 is located at one end of the connecting plate 3 near the first circuit board 1 along the width direction Y of the connecting plate 3. This arrangement reduces the amount of connecting plate 3 remaining on the first circuit board 1 after the connecting plate 3 is cut along the center of the first material reduction hole 31, thus reducing the space required to install the first circuit board 1 and minimizing space waste.

[0030] It is worth noting that if the connecting plate 3 is cut only along the center of the first material reduction hole 31, a large amount of the connecting plate 3 will remain on the second circuit board 2, resulting in a large space to be reserved in the electronic device 1000 for installing the second circuit board 2, thus causing a waste of space.

[0031] To at least partially solve the above problems, in some embodiments, the connecting plate 3 is further provided with a second material reduction hole 32. Along the width direction Y of the connecting plate 3, the first material reduction hole 31 and the second material reduction hole 32 are spaced apart. The first material reduction hole 31 is used to reduce the material of the connecting plate 3, facilitating cutting of the connecting plate 3. In this embodiment, by providing the second material reduction hole 32, and with the first material reduction hole 31 and the second material reduction hole 32 spaced apart along the width direction Y of the connecting plate 3, when cutting the connecting plate 3, it is possible to first cut along the center of the first material reduction hole 31, and then cut along the center of the second material reduction hole 32. This reduces the residue of the connecting plate 3 on the second circuit board 2, thereby reducing the space occupied by the cut second circuit board 2, reducing the space required in the electronic device 1000 for installing the second circuit board 2, and reducing space waste.

[0032] In some embodiments, there are multiple second material reduction holes 32, which are spaced apart along the length X of the connecting plate 3. All the second material reduction holes 32 are used to reduce the material of the connecting plate 3, further reducing the cutting difficulty. In this embodiment, by providing multiple second material reduction holes 32, when cutting the connecting plate 3, cutting can be performed along the center of the multiple second material reduction holes 32, which helps to further reduce the force required for cutting, reduce the cutting difficulty, and further reduce the material of the connecting plate 3, thus reducing costs.

[0033] It is worth noting that if the second material reduction hole 32 is set in the middle of the connecting plate 3 in the width direction Y of the connecting plate 3, after cutting along the center of the second material reduction hole 32, part of the connecting plate 3 will remain on the second circuit board 2, resulting in a large space occupied by the second circuit board 2. The electronic device 1000 needs to reserve a large space for installing the second circuit board 2, which can easily lead to space waste.

[0034] To at least partially solve the above problems, in some embodiments, the second material reduction hole 32 is located at one end of the connecting plate 3 near the second circuit board 2 along the width direction Y of the connecting plate 3. This arrangement reduces the amount of connecting plate 3 remaining on the second circuit board 2 after the connecting plate 3 is cut along the center of the second material reduction hole 32, thus reducing the space required to install the second circuit board 2 and minimizing space waste.

[0035] In some embodiments, please refer to Figure 3 When the first circuit board 1 and the second circuit board 2 are separated, the first circuit board 1 is provided with a first connecting part 11, and one end of the wire 4 is electrically connected to the first connecting part 11. The first circuit board 1 and the second circuit board 2 are electrically connected through the first connecting part 11 and the wire 4. In this embodiment, by providing the first connecting part 11, which is used to connect with the wire 4, the stability of the connection between the wire 4 and the first circuit board 1 is improved.

[0036] In some embodiments, when the first circuit board 1 and the second circuit board 2 are separated, the second circuit board 2 is provided with a second connecting portion 21, and the end of the wire 4 away from the first circuit board 1 is electrically connected to the second connecting portion 21. The first circuit board 1 and the second circuit board 2 are electrically connected through the first connecting portion 11, the wire 4, and the second connecting portion 21. In this embodiment, by providing the second connecting portion 21, which is used to connect with the wire 4, the stability of the connection between the wire 4 and the second circuit board 2 is improved.

[0037] In some embodiments, the second circuit board 2 is provided with at least one of a WIFI module, a Bluetooth module, and an antenna module.

[0038] In this embodiment, the first circuit board 1 and the second circuit board 2 are removably connected by a connecting plate 3. When the internal space of the electronic device 1000 is sufficient to simultaneously accommodate the first circuit board 1, the connecting plate 3, and the second circuit board 2 connected as one unit, the first circuit board 1, the connecting plate 3, and the second circuit board 2 connected as one unit can be directly installed inside the electronic device 1000. When the internal space of the electronic device 1000 cannot simultaneously accommodate the first circuit board 1, the connecting plate 3, and the second circuit board 2 connected as one unit, the first circuit board 1 and the second circuit board 2 can be cut at the connecting plate 3 to separate the first circuit board 1 and the second circuit board 2. The separated first circuit board 1 and the second circuit board 2 are electrically connected by wires 4, so that the first circuit board 1 and the second circuit board 2 can be installed in different positions of the electronic device 1000, so that the circuit board 100 can be used for various models of electronic devices 1000 without designing corresponding circuit boards 100 according to different models of electronic devices 1000, and the production line for producing the circuit board 100 can be reduced, which is beneficial to saving costs.
