Technical Field
[0001] This utility model relates to the field of coking production equipment, and in particular to a modular PCB board that is easy to install. Background Technology
[0002] In the field of modern electronics, PCBs, as key components of various electronic devices, are widely used in consumer electronics, industrial control, communication equipment, automotive electronics, and many other fields. From smartphones and tablets in daily life to automated equipment on industrial production lines, and from communication base stations to automotive electronic control systems, PCBs play a vital role in supporting electronic components and enabling electrical connections and signal transmission. With the continuous development of electronic technology, electronic devices are increasingly moving towards miniaturization, high performance, and multifunctionality, which places higher demands on the performance, ease of installation, and stability of PCBs.
[0003] Currently, traditional PCB boards present numerous problems during installation and use. In terms of installation, traditional PCB boards typically employ complex screw fixing or soldering methods, resulting in cumbersome installation steps and high requirements for the installation environment and operator skills. During installation, inaccurate positioning or operational errors can lead to damage to electronic components or render the PCB board unusable, resulting in low installation efficiency and high costs. During use, traditional PCB boards lack effective cushioning and securing measures. Electronic equipment is often subjected to external forces such as vibration and impact during operation, which can easily cause the PCB board to shift or loosen, leading to broken connection points, damaged electronic components, and ultimately, circuit failures. Furthermore, the heat dissipation performance of traditional PCB boards is generally insufficient; the heat generated by electronic components during operation is difficult to dissipate quickly, which not only affects the performance and lifespan of electronic components but can also cause the entire PCB board to overheat and fail.
[0004] In response to this technical problem, this application proposes a modular PCB board that is easy to install. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular PCB board that is easy to install. During the use or installation of the PCB board, the spacers effectively buffer impact forces, preventing damage to the overall structure due to impacts or drops. This design provides basic protection for the PCB board, reducing the risk of damage due to unexpected situations, ensuring the safety and stability of the PCB board, extending its service life, increasing structural stability, and improving connection reliability. Even when the PCB board is subjected to external forces such as vibration or shaking, the connection between the motherboard and the baseboard can be guaranteed to be stable, reducing circuit failures caused by loose connections and improving the reliability of the PCB board's operation.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A modular PCB board for easy installation includes a motherboard. The motherboard has multiple positioning holes on its front side and multiple positioning pins fixedly connected to its rear side. The motherboard has two first limiting holes on both the left and right sides of its top side. The motherboard is connected to a base plate via a connecting assembly on its bottom side. The base plate has two second limiting holes on both the left and right sides of its left and right sides. A buffer assembly is provided on the top side of the base plate. Multiple capacitors are provided on the top side of the motherboard. Multiple integrated circuits are provided on the outer periphery of the capacitors. The outer wall of the positioning pin is slidably connected to the inner wall of the positioning hole.
[0008] Furthermore, the connecting assembly includes a connecting post fixedly connected to the inside of the first limiting hole, a sliding groove is provided inside the connecting post, a screw is threadedly connected inside the sliding groove, a sliding rod is slidably connected to the bottom side of the screw, and a limiting plate is fixedly connected to the bottom end of the sliding rod.
[0009] Furthermore, a fixing plate is fixedly connected to the top of the screw, and a spring is provided on the bottom side of the fixing plate. One end of the spring is connected to the inside of the screw, and the other end is connected to the top side of the slide rod.
[0010] Furthermore, the buffer assembly includes multiple limiting posts fixedly connected to the bottom side of the motherboard, and multiple second limiting holes are provided on the top side of the base plate, with gaskets disposed inside the second limiting holes.
[0011] Furthermore, the bottom end of the limiting post is slidably connected to the inside of the second limiting hole, one side of the gasket is in contact with the bottom side of the limiting post, and the other side is in contact with the bottom side of the second limiting hole.
[0012] Furthermore, a limiting groove is provided on the bottom side of the second limiting hole, and the limiting groove is usually made of aerogel.
[0013] Furthermore, the bottom plate has multiple heat dissipation holes on its top side, and these holes penetrate the interior of the bottom plate.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, when installing the PCB board, the bottom limiting post of the main board is inserted into the second limiting hole on the top side of the base plate, and a gasket is placed inside the second limiting hole. During the use or installation of the PCB board, the gasket can effectively buffer the impact force, preventing damage to the overall structure due to impact or dropping. This design provides basic protection for the PCB board, reduces the risk of damage caused by accidents, ensures the safety and stability of the PCB board, and extends its service life.
[0016] 2. In this invention, the screw moves within the slide groove. When the limiting plate contacts the bottom of the slide groove, continued rotation of the fixing plate compresses the spring. The elastic potential energy generated by the spring reacts to the screw, further strengthening the connection between the screw and the slide groove. This design not only increases structural stability but also improves connection reliability. Even when the PCB board is subjected to external forces such as vibration or shaking, the connection between the main board and the base plate remains stable, reducing circuit failures caused by loose connections and improving the reliability of the PCB board operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1 and Figure 2This utility model provides an embodiment of a modular PCB board for easy installation, comprising a main board 1. The main board 1 has multiple positioning holes 4 on its front side and multiple positioning pins 6 fixedly connected to its rear side. Two first limiting holes 8 are formed at both ends of the top side of the main board 1. A base plate 9 is connected to the bottom side of the main board 1 via connecting posts 5. Two second limiting holes 11 are formed at both ends of the base plate 9. A gasket 13 is provided on the top side of the base plate 9. Multiple capacitors 3 are provided on the top side of the main board 1, and multiple integrated circuits 2 are arranged around the outer periphery of the capacitors 3. The outer wall of the positioning pins 6 is slidably connected to the inner wall of the positioning holes 4. A fixing plate 7 is fixedly connected to the top of a screw 14. A spring 15 is provided on the bottom side of the fixing plate 7. One end of the spring 15 is connected to the inside of the screw 14, and the other end is connected to the top side of a slide rod 16. The bottom end of the limiting post 12 is slidably connected to the inside of the second limiting hole 11. One side of the gasket 13 contacts the bottom side of the limiting post 12, and the other side contacts the bottom side of the second limiting hole 11. The second limiting hole 11 has a limiting groove 10 on its bottom side, which is usually made of aerogel. The bottom plate 9 has multiple heat dissipation holes 19 on its top side, which penetrate the interior of the bottom plate 9.
[0025] Specifically, during the PCB board installation, the first step is to place the base plate 9 in the predetermined installation position. Next, the main board 1 is carefully placed on top of the base plate 9. At this point, the limiting post 12 on the bottom side of the main board 1 will engage with the second limiting hole 11 on the top side of the base plate 9. After the initial construction of the anti-drop structure is completed, the positions of the main board 1 and the base plate 9 need to be fixed. Specifically, four connecting posts 5 are fixed at the four corners of the main board 1 and the base plate 9. After the connecting posts 5 are fixed, the screw 14 is inserted into the sliding groove 18 inside the connecting post 5. Here, the thread direction of the outer wall of the screw 14 is opposite to that of the inner wall of the sliding groove 18. By rotating the fixing plate 7, the screw 14 will move vertically into the sliding groove 18 under the action of the threaded connection.
[0026] Reference Figure 4 A connecting post 5 is fixedly connected inside the first limiting hole 8. A sliding groove 18 is opened inside the connecting post 5. A screw 14 is threaded inside the sliding groove 18. A sliding rod 16 is slidably connected to the bottom side of the screw 14. A limiting plate 17 is fixedly connected to the bottom end of the sliding rod 16.
[0027] Specifically, when the screw 14 moves to a certain position, the slide rod 16, which is slidably connected to the bottom of the screw 14, and the limiting plate 17 fixed to the bottom of the slide rod 16, will contact the bottom end of the inner side of the groove 18. After this, if the fixing plate 7 continues to rotate to drive the screw 14 to move, the spring 15 set at the top of the limiting plate 17 will be compressed and deformed. The elastic potential energy generated by the deformation of the spring 15 will exert a reaction force on the screw 14, making the connection between the screw 14 and the groove 18 tighter, thereby enhancing the stability of the overall structure.
[0028] Reference Figure 3 The bottom side of the motherboard 1 is fixedly connected with multiple limiting posts 12, and the top side of the base plate 9 is provided with multiple second limiting holes 11, and a gasket 13 is provided inside the second limiting hole 11.
[0029] Specifically, a gasket 13 is placed inside the second limiting hole 11. After the motherboard 1 is placed, the bottom end of the limiting post 12 will fit tightly against the gasket 13 under the action of gravity. This design can effectively prevent the PCB board from being damaged by impact during use or from being accidentally dropped during installation.
[0030] Working principle: When installing the PCB board, the operator first places the base plate 9 in the installation position, and then places the main board 1 on top of the base plate 9. The limiting post 12 on the bottom side of the main board 1 is inserted into the second limiting hole 11 on the top side of the base plate 9. A gasket 13 is placed inside the second limiting hole 11. After the main board 1 is placed, under the action of gravity, the bottom end of the limiting post 12 and the gasket 13 are tightly fitted to each other, preventing the PCB from being damaged by impact during use or falling during installation. After the anti-drop mechanism is assembled, the main board 1 and the base plate 9 need to be fixed in position. Four connecting posts 5 are fixed at the four corners of the main board 1 and the base plate 9 respectively. After the connecting posts 5 are fixed in position, the screw 14 is tightened. The body is placed in the groove 18 inside the connecting column 5. The threads on the outer wall of the screw 14 are opposite in direction to those on the inner wall of the groove 18. Under the action of the threaded connection, rotating the fixing plate 7 causes the screw 14 to move vertically into the groove 18. After moving to a certain position, the sliding rod 16 on the bottom side of the screw 14, and the limiting plate 17 fixed at its bottom, will contact the bottom end of the groove 18. At this time, continuing to rotate the fixing plate 7 will drive the screw 14 to move. The elastic potential energy generated by the deformation of the spring 15 at the top of the limiting plate 17 under compression will exert a reaction force on the screw 14, making the connection between the screw 14 and the groove 18 tighter and increasing the structural stability. According to the functional requirements of the electronic equipment, the corresponding functional module PCB board is selected. The various small PCB boards are arranged according to the design requirements, and the positioning pins 6 are accurately inserted into the positioning holes 4 to complete the initial positioning. Then, the adjacent small PCB boards are connected by welding or other reliable connection methods to form a complete modular PCB board.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
