Description

Technical Field

[0001] This utility model relates to an IO control card, specifically a high-precision measurement IO control card, and belongs to the field of control card technology. Background Technology

[0002] An I / O controller card, also known as an I / O interface controller card, is a hardware device. It consists of several integrated circuits arranged in a specific logic to facilitate data exchange and control between a computer and external devices. It is typically inserted into a computer's expansion slot, acting as a bridge between the computer and external devices, responsible for data transmission and processing. The I / O controller card receives different commands and parameters from the CPU and controls the relevant I / O circuits and simple peripherals to perform corresponding operations. When the computer needs to exchange data with an external device, the CPU sends instructions and data to the I / O controller card. Upon receiving the instructions and data, the I / O controller card will send data to the external device or receive data from the external device according to the requirements of the instructions, and then transmit the data back to the CPU for processing.

[0003] Currently, most I / O control cards rely on plug-in ports to achieve a stable connection with the computer. However, in practical applications, this plug-in method has a common problem: during frequent plugging and unplugging, the plug-in port is prone to loosening due to physical wear or improper operation. Once the plug-in port becomes loose, the contact between the port and the circuit board on the control board becomes unstable, and may even result in poor contact. This poor contact will directly affect the normal transmission of data, leading to a series of problems such as reduced data transmission speed, data loss, or transmission errors. To address this, a high-precision measurement I / O control card is proposed. Utility Model Content

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, this utility model embodiment provides a high-precision measurement I / O control card, including a connection terminal 11, and a connection component 101 is installed on the outside of the connection terminal 11; the connection component 101 is used to reinforce the connection between the connection terminal 11 and the circuit board 39.

[0028] The opposing surfaces of the upper pressure plate 17 and the lower pressure plate 19 are respectively attached to the upper and lower surfaces of the circuit board 39. The threaded sleeve 21 is located inside the positioning hole 38. The upper surface of the limiting seat 22 is attached to the lower surface of the lower pressure plate 19. The upper surface of the circuit board 39 is provided with positioning holes 38 and mounting holes 37. By clamping the circuit board 39 with the upper pressure plate 17 and the lower pressure plate 19, the connecting plate 12 can be tightly connected to the circuit board 39. Since the connecting plate 12 is fixed outside the connecting terminal 11, the connection between the connecting terminal 11 and the circuit board 39 can be strengthened, preventing the connection between the connecting terminal 11 and the circuit board 39 from becoming loose, enhancing the stability between the connecting terminal 11 and the circuit board 39, and ensuring normal data transmission.

[0029] The connecting assembly 101 includes a connecting plate 12, a reinforcing plate 13, a reinforcing knob 14, a limiting plate 15, a stud 16, an upper pressure plate 17, a lower pressure plate 19, a threaded sleeve 21, and a limiting seat 22.

[0030] The connecting plate 12 is fixedly connected to the outer wall of the connecting terminal 11. The two upper pressure plates 17 and the two lower pressure plates 19 are symmetrically fixedly connected to the rear surface of the connecting plate 12. The reinforcing plate 13 is fixedly connected to the upper pressure plate 17 and the connecting plate 12 respectively. The reinforcing plate 13 can further enhance the firmness between the upper pressure plate 17 and the connecting plate 12.

[0031] The reinforcing knob 14 is fixedly connected to the upper surface of the limiting plate 15, and the limiting plate 15 is fixedly connected to the top of the stud 16. Thus, when the reinforcing knob 14 is rotated, the limiting plate 15 drives the stud 16 to rotate.

[0032] The bottom end of the threaded sleeve 21 is fixedly connected to the upper surface of the limiting seat 22. The upper pressure plate 17 has a through hole 18 inside, and the lower pressure plate 19 has a limiting hole 20 inside. The position of the through hole 18 corresponds to the position of the limiting hole 20. The threaded sleeve 21 is located inside the through hole 18. Through the through hole 18 and the limiting hole 20, installation space can be reserved for the threaded sleeve 21 and the stud 16.

[0033] The stud 16 is threaded to the inner wall of the threaded sleeve 21. The limiting seat 22 is located inside the limiting hole 20. The lower surface of the limiting plate 15 is attached to the upper surface of the upper pressure plate 17. When reinforcing the connection between the connecting terminal 11 and the circuit board 39, the upper pressure plate 17 and the lower pressure plate 19 are respectively clamped above and below the circuit board 39. Then, the connecting plate 12 is welded to the outer wall of the connecting terminal 11. The threaded sleeve 21 is inserted upward from the limiting hole 20 into the positioning hole 38 and the through hole 18. Then, the stud 16 is inserted into the inside of the threaded sleeve 21. The stud 16 is rotated by the reinforcing knob 14, thereby completing the connection between the upper pressure plate 17 and the lower pressure plate 19. At this time, the connecting terminal 11, the connecting plate 12 and the circuit board 39 are reinforced.

[0034] In one embodiment, the rear surface of the upper pressure plate 17 is fixedly connected to a solder pad 23, which allows the upper pressure plate 17 to be soldered onto the circuit board 39, thereby enhancing the overall robustness.

[0035] In one embodiment, a main component 301 is mounted on the outside of the connection terminal 11. The main component 301 includes a conversion chip 31, an input / output interface terminal 32, a register 33, a power management module 34, a CPU 35, a communication chip 36, and a circuit board 39.

[0036] The conversion chip 31, input / output interface terminal 32, register 33, power management module 34, CPU 35 and communication chip 36 are all mounted on the upper surface of the circuit board 39.

[0037] The conversion chip 31 is responsible for converting analog signals into digital signals (A / D conversion) or digital signals into analog signals (D / A conversion), which is crucial for high-precision measurement and ensures accurate signal transmission and processing.

[0038] The input / output interface 32 includes digital input / output interfaces and analog input / output interfaces, which are used to connect external devices such as sensors and actuators. The input / output interface 32 can ensure accurate signal transmission and reliable control of the device.

[0039] Register 33 includes a control register and a status register, which are responsible for storing data and instructions. When the program needs to read or write data, it will interact with the corresponding register 33.

[0040] The power management module 34 is used to provide a stable power supply for the control card, ensuring the normal operation of each electronic component. It also has overvoltage and overcurrent protection functions to improve the safety of the system.

[0041] CPU35 is responsible for data processing, instruction execution, and program flow management. CPU35 can quickly process large amounts of data, improving the real-time performance and accuracy of the system.

[0042] The communication chip 36 is used to enable communication between the control card and other devices or systems.

[0043] In operation, the present invention involves: clamping the upper pressure plate 17 and the lower pressure plate 19 above and below the circuit board 39, respectively; welding the connecting plate 12 to the outer wall of the connecting terminal 11; inserting the threaded sleeve 21 upward from the limiting hole 20 into the positioning hole 38 and the through hole 18; inserting the stud 16 into the inside of the threaded sleeve 21; and rotating the stud 16 by the reinforcing knob 14, thereby completing the connection between the upper pressure plate 17 and the lower pressure plate 19. At this time, the connecting terminal 11, the connecting plate 12, and the circuit board 39 are reinforced. By clamping the circuit board 39 with the upper pressure plate 17 and the lower pressure plate 19, the connecting plate 12 and the circuit board 39 can be securely connected. Since the connecting plate 12 is fixed outside the connecting terminal 11, the connection between the connecting terminal 11 and the circuit board 39 can be reinforced, preventing loosening between the connecting terminal 11 and the circuit board 39, enhancing the stability between the connecting terminal 11 and the circuit board 39, and ensuring normal data transmission.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
