The communication control circuit board also features a rich variety of interface types. In addition to the common USB interface for device debugging and program updates, there are multiple ports for connecting external devices.

[0004] The circuit board is fixed inside the housing with bolts. Since the bolts used to fix the circuit board are usually tightened manually, if the tightening force is too large, the circuit board substrate will bend or warp. Over time, this deformation will affect the component layout and electrical connection. Utility Model Content

[0005] The purpose of this application is to provide a communication control circuit board to solve the problem mentioned in the background art that when the tightening force of the bolt is too large, the excessive tightening force will cause the circuit board substrate to bend or warp. Over time, this deformation will affect the component layout and electrical connection.

[0006] To achieve the above objectives, this application provides the following technical solution: a communication control circuit board, comprising: a circuit board body, a fixing plate, and a positioning and fixing mechanism. The circuit board body has holes around its perimeter for installation. The fixing plate is disposed at the bottom of the circuit board body.

The positioning and fixing mechanism includes positioning posts welded to the outer wall of the fixing plate, a first rectangular groove opened at the top of the positioning posts, a second rectangular groove opened on both sides of the inner wall of the first rectangular groove, a rectangular slider slidably connected in the second rectangular groove, a connecting shaft welded to the rectangular slider, and an "O" block rotatably connected to the connecting shaft.

[0007] By adopting the above technical solution, the circuit board body can be quickly fixed by flipping.

[0008] Preferably, the positioning and fixing mechanism further includes an annular groove formed on the outer wall of the "O" block.

[0009] By adopting the above technical solution, it is possible to provide a structure inside the annular groove that enables rotational displacement.

[0010] Preferably, the positioning and fixing mechanism further includes a circular groove vertically formed at the bottom of the first rectangular groove.

[0011] By adopting the above technical solution, the circular groove can provide an internal structure for storage, thereby achieving the effect of placement and organization.

[0012] Preferably, the positioning and fixing mechanism further includes a spring with its bottom end welded to the bottom of a circular groove, and the top end of the spring is integrally formed with a hook.

[0013] By adopting the above technical solution, the top structure can be fixed by using an integrally molded hook.

[0014] Preferably, the positioning and fixing mechanism further includes a pulley disposed on a hook at the top of the spring, the pulley being slidably connected inside the annular groove.

[0015] By adopting the above technical solution, it is possible to provide a stable position change of the pulley inside the annular groove, thereby enabling the spring to lift and displace the "O" block.

[0016] Preferably, the positioning and fixing mechanism further includes an arc-shaped groove formed around the inner wall of the annular groove, the size of which is adapted to the size of the pulley.

[0017] By adopting the above technical solution, the pulley can be positioned during the contact process.

[0018] In summary, this application has the following beneficial effects: by providing a positioning and fixing mechanism, when it is necessary to fix the circuit board body, the circuit board body can be quickly fixed without the aid of external tools by inserting it into the positioning and fixing mechanism and flipping it over. Moreover, the fixing method of the circuit board body adopts a spring-loaded connection method. When the fixed connection part of the circuit board body is subjected to external vibration, it provides a certain degree of elasticity to reduce direct collision, effectively avoiding affecting the component layout and electrical connection, and improving the overall structural stability of the circuit board body.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0026] Example 1

[0027] Please see Figures 1-4 This embodiment provides a technical solution: a circuit board with communication control, comprising: a circuit board body 1, a fixing plate 2, and a positioning and fixing mechanism 3;

[0028] The main body of the circuit board 1 is compatible with the Ethernet communication protocol to achieve high-speed and stable local area network data transmission for real-time parameter interaction with the host computer monitoring system. It also supports the serial communication protocol for easy connection to some traditional sensors or actuators, ensuring coordinated operation between various parts of the device. The main body of the circuit board 1 also features a rich variety of interface types. In addition to the common USB interface for device debugging and program updates, there are multiple ports for connecting external devices. These are existing technologies and will not be elaborated further below.

[0029] The fixing plate 2 is set at the bottom of the circuit board body 1, and the positioning and fixing mechanism 3 is set around the outer wall of the fixing plate 2. The positioning and fixing mechanism 3 includes a positioning post 301 welded around the outer wall of the fixing plate 2, a first rectangular groove 302 opened on the top of the positioning post 301, a second rectangular groove 303 opened on both sides of the inner wall of the first rectangular groove 302, a rectangular slider 304 slidably connected in the second rectangular groove 303, a connecting shaft 305 welded to the rectangular slider 304, and an "O" block 306 rotatably connected to the connecting shaft 305.

[0030] The fixing plate 2 is fixed inside the housing to be installed by bolts. When it is necessary to fix the circuit board body 1 on the fixing plate 2, the positioning and fixing mechanism 3 can quickly fix the circuit board body 1 on the fixing plate 2.

[0031] The "O" block 306 is rotated via the connecting shaft 305. During this rotation, the "O" block 306 remains vertical within the first rectangular groove 302 of the positioning post 301. The mounting hole of the circuit board body 1 is then inserted into the positioning post 301. The "O" block 306 on the connecting shaft 305 continues to rotate, changing from a vertical to a horizontal position. The "O" block 306 then moves vertically within the second rectangular groove 303 via the rectangular sliders 304 at both ends of the connecting shaft 305. At this point, the bottom end of the "O" block 306 will be attached to the outer wall of the mounting hole of the circuit board body 1.

[0032] Example 2

[0033] Please see Figures 1-4 This embodiment provides a technical solution: a communication control circuit board, including: an annular groove 307, a circular groove 308, a spring 309, a pulley 310 and an arc-shaped groove 311;

[0034] An annular groove 307 is formed on the outer wall of the "O"-shaped block 306. A circular groove 308 is formed vertically at the bottom of the first rectangular groove 302. A spring 309 is welded to the bottom of the circular groove 308. A hook is integrally formed at the top of the spring 309. A pulley 310 is set on the hook at the top of the spring 309. The pulley 310 is slidably connected to the inside of the annular groove 307. An arc-shaped groove 311 is formed around the inner wall of the annular groove 307. The size of the arc-shaped groove 311 is adapted to the size of the pulley 310.

[0035] When the "O" block 306 rotates, the pulley 310 inside the annular groove 307 can simultaneously change position. The pulley 310 is connected to the spring 309 inside the circular groove 308. At this time, the pulley 310 inside the annular groove 307 will be lifted by the spring 309, thereby synchronously driving the "O" block 306 to stably adhere to the outer wall of the mounting hole of the circuit board body 1. When the "O" block 306 is kept in a horizontal state, the pulley 310 will be inside the arc-shaped groove 311, providing stability when the "O" block 306 is kept in a horizontal state.

[0036] The implementation principle of the communication control circuit board of this application is as follows:

[0037] First, the mounting plate 2 is fixed inside the housing to be installed using bolts. When the circuit board body 1 needs to be fixed to the mounting plate 2, the positioning and fixing mechanism 3 can quickly fix the circuit board body 1 to the mounting plate 2. The circuit board body 1 is also compatible with the Ethernet communication protocol to achieve high-speed and stable local area network data transmission for real-time parameter interaction with the host computer monitoring system. It also supports the serial communication protocol, facilitating connection with some traditional sensors or actuators to ensure coordinated operation between various parts of the device. The circuit board body 1 also has a variety of interface types. In addition to the common USB interface for device debugging and program updates, there are multiple ports for connecting external devices.

[0038] Next, the "O" block 306 is rotated via the connecting shaft 305. During this rotation, the "O" block 306 remains vertical within the first rectangular groove 302 of the positioning post 301. The mounting hole of the circuit board body 1 is then inserted into the positioning post 301. The "O" block 306 on the connecting shaft 305 continues to rotate, changing from a vertical to a horizontal position. The "O" block 306 then moves vertically within the second rectangular groove 303 via the rectangular sliders 304 at both ends of the connecting shaft 305. At this point, the bottom of the "O" block 306 will be attached to the outer wall of the mounting hole of the circuit board body 1.

[0039] Finally, when the "O" block 306 rotates, the pulley 310 inside the annular groove 307 can synchronously change its position. The pulley 310 is connected to the spring 309 inside the circular groove 308. At this time, the pulley 310 inside the annular groove 307 will be lifted by the spring 309, thereby synchronously driving the "O" block 306 to stably adhere to the outer wall of the mounting hole of the circuit board body 1. When the "O" block 306 is kept in a horizontal state, the pulley 310 will be inside the arc-shaped groove 311, providing stability when the "O" block 306 is kept in a horizontal state.

[0040] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
