For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0036] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it.

[0037] Figure 1 This is a schematic diagram of the structure of a modular circuit board provided in an embodiment of the present application. Figure 1 As shown, the combined circuit board 100 includes a first circuit board 10 and a second circuit board 20. The first circuit board 10 is provided with a pinhole, and the second circuit board 20 is also provided with a pinhole. Pins can be inserted into the pinholes. The first circuit board 10 and the second circuit board 20 are electrically connected via the pins to achieve communication between the two circuit boards. The first circuit board 10 can be the main circuit board of the device, and the second circuit board 20 can be a secondary functional circuit board of the device.
[0038] The first circuit board 10 has at least two insertion holes 101 , and the number of the insertion holes 101 can be two or more.
[0039] The second circuit board 20 has at least two protrusions 201 on the same side. The number of protrusions 201 can be the same as the number of sockets 101, or can be two or more. For example, the number of sockets 101 and protrusions 201 can both be two, or can both be three, which is not limited in this application.
[0040] The socket 101 is used to cooperate with the protrusion 201, and the first circuit board 10 and the second circuit board 20 are fixed together by the socket 101 and the protrusion 201 to form a vertical plug-in type combined circuit board. In this application, the circuit board is designed as a vertical plug-in type combined circuit board, which utilizes vertical space, reduces the area occupied by traditional flat-plate circuit boards, and reduces the electrical control space. The protrusion 201 is inserted into the socket 101. After the socket 101 and the protrusion 201 are plugged in, they can be reinforced by welding at the bottom of the circuit board. The socket-type installation and welding make the circuit board assembly more secure, and multiple welding positions can also be used for signal transmission.
[0041] Of course, the combined circuit board of the present application may include multiple first circuit boards and multiple second circuit boards, which can be combined together by simply setting corresponding jacks and protrusions.
[0042] In some embodiments, such as Figure 2As shown, the jack 101 on the first circuit board 10 can be configured as an elongated hole. Multiple elongated holes are arranged in a straight line along their length. At least two of the elongated holes have different lengths. The different jack lengths and protrusion lengths mean that only those of the same length can be plugged together when the two are plugged in, thus preventing reverse insertion.
[0043] In some embodiments, such as Figure 2 As shown, the socket 101 on the first circuit board 10 is located in the middle of the first circuit board 10, which can facilitate the plug-in installation of the socket and the protrusion and reduce the difficulty of installation.
[0044] In some embodiments, such as Figure 3 As shown, the second circuit board 20 can be set as a metal-based plate, and the heating device required for the combined circuit board is installed on the second circuit board 20. The heating device is installed on the metal-based plate. Since the metal has good thermal conductivity, and the second circuit board 20 is vertically inserted in the middle of the first circuit board 10, with no obstruction on both sides, the heat dissipation effect of the circuit board can be greatly improved. Specifically, the second circuit board 20 can be set as an aluminum-based plate or a copper-based plate. The first circuit board 10 can be set as a more durable FR4 plate, or it can be set as a common material such as a polymer plastic plate, a ceramic plate, etc.
[0045] In some embodiments, such as Figure 4 As shown, the pins can be L-shaped pin headers, with both ends of the pins soldered to the first circuit board 10 and the second circuit board 20, respectively. Specifically, one end of the L-shaped pin header can be pre-soldered to the second circuit board 20. When the second circuit board 20 is inserted into the first circuit board 10, the other end of the L-shaped pin header simultaneously inserts into the pinholes of the first circuit board 10. The L-shaped pin header can assist in signal transmission while supporting the second circuit board 20, allowing it to remain vertical during installation. The L-shaped pin header connects two circuit boards simultaneously, simplifying circuit board assembly.
[0046] The modular circuit board of an embodiment of the present application includes a first circuit board having at least two sockets; and a second circuit board having at least two protrusions on the same side. The sockets are configured to engage with the protrusions, and the first and second circuit boards are secured together by the sockets and protrusions to form a vertical plug-in modular circuit board. The first and second circuit boards are electrically connected via pins. Compared to the prior art, this solution utilizes vertical space, reduces the area occupied by traditional flat-plate circuit boards, and reduces electrical control space. This significantly improves the modular circuit board's heat dissipation and reduces assembly difficulty.
[0047] like Figure 5As shown, the embodiment of the present application provides an air conditioning device, including a combined circuit board 100. Figure 1 As shown, the combined circuit board 100 includes a first circuit board 10 and a second circuit board 20. The first circuit board 10 is provided with a pinhole, and the second circuit board 20 is also provided with a pinhole. Pins can be inserted into the pinholes. The first circuit board 10 and the second circuit board 20 are electrically connected via the pins to achieve communication between the two circuit boards. The first circuit board 10 can be the main circuit board of the device, and the second circuit board 20 can be a secondary functional circuit board of the device.
[0048] The first circuit board 10 has at least two insertion holes 101 , and the number of the insertion holes 101 can be two or more.
[0049] The second circuit board 20 has at least two protrusions 201 on the same side. The number of protrusions 201 can be the same as the number of sockets 101, or can be two or more. For example, the number of sockets 101 and protrusions 201 can both be two, or can both be three, which is not limited in this application.
[0050] The socket 101 is used to cooperate with the protrusion 201, and the socket 101 and protrusion 201 are used to fix the first circuit board 10 and the second circuit board 20 to form a vertical plug-in type combined circuit board. In this application, the circuit board is designed as a vertical plug-in type combined circuit board, which utilizes vertical space, reduces the area occupied by traditional flat circuit boards, and reduces the electrical control space. The protrusion 201 is inserted into the socket 101. After the socket 101 and the protrusion 201 are plugged in, they can be reinforced by welding at the bottom. The socket-type installation and welding make the circuit board assembly more secure, and the multiple welding positions can also be used for signal transmission.
[0051] In some embodiments, such as Figure 2 As shown, the jack 101 on the first circuit board 10 can be configured as an elongated hole. Multiple elongated holes are arranged in a straight line along their length. At least two of the elongated holes have different lengths. The different jack lengths and protrusion lengths mean that only those of the same length can be plugged together when the two are plugged in, thus preventing reverse insertion.
[0052] In some embodiments, such as Figure 2 As shown, the socket 101 on the first circuit board 10 is located in the middle of the first circuit board 10, which can facilitate the plug-in installation of the socket and the protrusion and reduce the difficulty of installation.
[0053] In some embodiments, the second circuit board 20 can be configured as a metal-based plate material, and the heating device required for the combined circuit board is installed on the second circuit board 20. The heating device is installed on the metal-based plate material. Since the metal has good thermal conductivity, and the second circuit board 20 is vertically inserted in the middle of the first circuit board 10 with no obstruction on both sides, the heat dissipation effect of the circuit board can be greatly improved. Specifically, the second circuit board 20 can be configured as an aluminum-based plate material or a copper-based plate material. The first circuit board 10 can be configured as a more durable FR4 plate material, or it can be configured as a common material such as a polymer plastic plate material, a ceramic plate material, etc.
[0054] FR4 is a code name for a flame-resistant material grade, which means that the resin material must be able to extinguish itself after burning. It is not a material name, but a material grade. Therefore, there are many types of FR4 grade materials used in general circuit boards, but most of them are composite materials made of so-called quad-functional epoxy resin, fillers and glass fiber.
[0055] Aluminum-based laminates are metal-based copper-clad laminates with excellent heat dissipation. Single-sided laminates typically consist of three layers: a circuit layer (copper foil), an insulating layer, and a metal base layer. Double-sided laminates for high-end applications also have a structure consisting of a circuit layer, an insulating layer, an aluminum base, an insulating layer, and a circuit layer. A very rare application involves multi-layer laminates, which can be constructed by laminating a conventional multi-layer laminate with an insulating layer and an aluminum base.
[0056] Copper substrate is also a metal substrate, and its thermal conductivity is many times better than that of aluminum substrate.
[0057] In some embodiments, such as Figure 3 As shown, the pins can be L-shaped pin headers, with both ends of the pins soldered to the first circuit board 10 and the second circuit board 20, respectively. Specifically, one end of the L-shaped pin header can be pre-soldered to the second circuit board 20. When the second circuit board 20 is inserted into the first circuit board 10, the other end of the L-shaped pin header simultaneously inserts into the pinholes of the first circuit board 10. The L-shaped pin header can assist in signal transmission while supporting the second circuit board 20, allowing it to remain vertical during installation. The L-shaped pin header connects two circuit boards simultaneously, simplifying circuit board assembly.
[0058] Compared with the existing technology, the present application designs the circuit board into a modular circuit board in the form of a plug-in, utilizes the vertical space, reduces the area occupied by the traditional flat circuit board, reduces the electrical control space, and can greatly improve the heat dissipation effect of the modular circuit board and reduce the difficulty of assembly.
[0059] In air-conditioning equipment, the area occupied by the circuit board and the heat dissipation effect are important indicators affecting the performance of the air-conditioning equipment. Therefore, the above-mentioned combined circuit board provided in this application can be applied to air-conditioning equipment to improve the performance of the air-conditioning equipment.
