Description

Technical Field

[0001] The utility model relates to the technical field of signal conversion modules, and specifically provides a signal conversion module. Background Art

[0002] A signal conversion module is a portable interface that collects sensor signals, converts the signals, and then sends them to a computer. Most signal conversion modules are circuit boards. During the process of docking with a computer, additional devices are needed for auxiliary fixation. At the same time, it is necessary to ensure indicators such as the insulation and anti-interference of the circuit board. As a result, in the process of industrial application of the existing signal conversion modules, their usage effect is reduced, and various troubles are brought to users. For example, during the process of collecting and converting signals in a harsh environment, it is necessary to consider the influence of the detection environment on the signals and perform operations such as error processing on the detected signals. At the same time, various complex designs such as insulation, anti-interference, anti-static, electromagnetic shielding, and dust prevention need to be carried out for the signal conversion module according to the working environment.

[0003] The existing signal conversion modules also have problems, including: during the process of adapting and docking with various sensors, assembly is required and the consistency of the interfaces needs to be ensured, which also brings trouble to users. That is, when users purchase signal conversion modules, they need to carefully examine the interfaces of the signal conversion modules, select appropriate sensors, and require the sensors to be compatible with the interfaces of the signal conversion modules. Otherwise, the detection cannot be carried out, which brings many problems to users. Not only a large amount of energy is required in the process of selecting chip models, but also factors such as the connection stability of the interfaces need to be considered during the installation of the signal conversion modules and the corresponding sensors, greatly increasing the usage cost of the signal conversion modules and reducing their market prospects. In addition, the existing signal conversion modules are usually fixed by screws, which leads to the need to screw multiple screws (usually four, two on each of the left and right sides) one by one when disassembling and assembling the signal conversion modules, wasting time. Therefore, a signal conversion module is invented. Summary of the Utility Model
