Description

Technical Field

[0001] The invention relates to the technical field of PLC testing, and in particular to an integrated testing tool for PLC cabinet fuse terminals. Background Art

[0002] In modern industrial automation systems, PLC (Programmable Logic Controller) is widely used in various automation control and monitoring tasks, and is the core component to ensure system stability and efficiency. Therefore, PLC testing is crucial to the normal operation of the entire industrial automation system. The accuracy and efficiency of the test directly affect the reliability, safety and operating cost of the system. However, the existing PLC testing process still has many limitations and technical difficulties, and needs to be improved urgently.

[0003] At present, PLC testing mainly relies on manual operation, which is complex and error-prone. First, technicians need to manually set the test program according to the specific configuration of the PLC cabinet to be tested. This process usually requires an in-depth understanding of the specifications, functions and interfaces of each PLC module to ensure that the test program can cover all possible working scenarios. However, due to the wide variety and complex configuration of PLC modules, technicians not only need to spend a lot of time setting up the test program, but also easily lead to incomplete coverage or setting errors due to negligence of details.

[0004] After the test program is set up, the tester needs to manually connect the test program with each PLC module according to the program requirements. This process is extremely challenging. Due to its complexity, it has a low fault tolerance rate. A slight mistake may lead to connection errors or missed connections, thus affecting the accuracy of the test results. This manual connection process is particularly time-consuming in actual operation, and usually requires at least two technicians to work together, which increases labor costs and operation time. At the same time, due to the large number of manual operations during the test process, any irregular operation may cause system failures, further reducing the reliability of the test.

[0005] In addition, as the scale and complexity of industrial automation systems continue to increase, traditional manual PLC testing methods can no longer meet the growing demand. During large-scale PLC system testing, problems such as low efficiency and high error rate of manual operation become more prominent, resulting in increased testing costs, longer testing cycles, and even affecting the overall progress of the project.

[0006] In summary, these defects of the existing technology seriously affect the efficiency and reliability of PLC testing, especially in industrial scenarios with increasing automation. Therefore, there is an urgent need for a solution that can simplify the PLC testing process, improve test accuracy and efficiency, reduce reliance on manual operations, reduce the risk of errors, and save manpower and time costs, thereby improving overall testing performance and ensuring the stability and efficiency of industrial automation systems. Summary of the invention

[0066] Implementation Method XI: Combination Figure 1-7 This embodiment is described in detail by using specific examples to further describe the technical solution provided above. Specifically:

[0067] The PLC cabinet fuse terminal integrated test fixture of this embodiment comprehensively solves the problems of low efficiency, high error rate and increased testing cost in the prior art through multiple structural optimizations, and provides a more efficient, stable and flexible test operation solution. The solution improves the overall performance through a series of carefully designed structures and components, adapts to various complex test environments, and enhances the operability, test accuracy and maintenance convenience of the equipment.

[0068] First, the shell of a PLC cabinet fuse terminal integrated test tool adopts a rectangular structure, and a through hole for accommodating contact 4 is provided on one of the side walls with the smallest surface area. Contact 4 is designed as a cylinder and connected to the base through a spring 5, which ensures the stability and good telescopic performance of contact 4. The spring 5 structure provides a constant contact pressure for contact 4, so that it can maintain reliable contact during high-frequency testing, avoiding problems such as poor contact and unstable signal transmission. The design of the cylindrical contact 4 further increases the contact area, ensures accurate signal transmission, and provides a stable operating experience even in high-frequency testing scenarios.

[0069] The parallel and staggered arrangement of sub-terminals 1 and 2 is one of the core innovations of this implementation. By staggering the terminals in space, not only the mutual interference between terminal groups is reduced, but also the space utilization and intuitiveness of operation are improved. This layout design greatly simplifies the wiring and operation process, and reduces the risk of operational errors caused by complex connections. Especially in a multi-terminal testing environment, users can more easily identify and connect each terminal. This design effectively reduces the probability of misoperation and wrong connection, improves the safety and accuracy of the test, and provides more flexibility for system expansion, allowing more terminal groups to be used simultaneously in a limited space.

[0070] The grooves and fixing slots in the housing, when used in conjunction with the back clip, significantly improve the convenience of installation and removal of the equipment. The back clip is designed as a rectangular structure, and a protrusion is provided at one end close to the fuse terminal to enhance the firmness of the connection. This modular design allows the test terminals to be quickly fixed or removed without the use of complex tools. Users can flexibly replace the terminal group according to different test requirements, greatly reducing the preparation and maintenance time of the equipment, which is particularly suitable for test scenarios that require frequent terminal replacement. In addition, the modular design of the back clip structure makes the expansion of the terminal group more flexible, enhancing the adaptability and scalability of the entire system.

[0071] In order to ensure that the management of cables during the test is more standardized and orderly, this embodiment also provides a cable channel and a cable clamp 3 on the top of the housing. The cable channel is used to introduce the cable, while the cable clamp 3 fixes the cable to prevent it from sliding or loosening during the test. This design not only ensures the stability of the cable during the test and avoids signal transmission interruption, but also maintains the neatness and safety of the entire test environment. In a complex test environment, especially in a scenario where multiple cables are working at the same time, the cable clamp 3 can effectively improve the convenience of operation and significantly reduce the safety hazards caused by improper cable management.

[0072] The design of the insurance test plug further enhances the flexibility and adaptability of this implementation in actual operation. The plug is connected to the sub-terminal one and sub-terminal two in multiple terminal groups through wires, so that multiple terminal groups can participate in the test at the same time, supporting multi-channel parallel operation, and greatly improving the processing capacity of the system. The modular connection method between the plug and the terminal group not only simplifies the wiring process and ensures the stable transmission of the test signal, but also enhances the adaptability of the system in complex test scenarios. Users can quickly replace plugs and terminal groups according to different test requirements, which greatly improves operating efficiency and reduces signal interference and transmission loss.

[0073] Finally, the design of the insurance PLC test cabinet of this embodiment integrates multiple PLC cabinet insurance terminal integrated test fixtures and plugs to support simultaneous testing of multiple PLC devices. Fixed locations for various test equipment are provided inside the cabinet, and operators can flexibly deploy and replace test components according to actual needs. The cabinet is connected to the PLC device under test through a insurance test plug, supports synchronous testing of multiple channels and multiple devices, and ensures the flexibility and efficiency of the test environment. Especially in large-scale testing scenarios, the modular expansion design of the cabinet enables it to quickly adapt to new testing requirements, significantly improving the overall testing efficiency.

[0074] Through the optimization and implementation of the above-mentioned multiple designs, this implementation not only effectively solves the problems of low test efficiency and high error rate in the prior art, but also further improves the operational convenience, test accuracy, and flexibility and scalability of the equipment. In future test system upgrades or functional expansions, this solution has good adaptability and can be adjusted and optimized according to different test requirements, showing significant technical advantages.

[0075] The technical solution provided by the present invention is further described in detail above through several specific implementation modes in order to highlight the advantages and benefits of the technical solution provided by the present invention. However, the several specific implementation modes described above are not intended to be used as limitations on the present invention.
