Description

TECHNICAL FIELD

[0001] The application relates to the technical field of PLC testing, and particularly relates to a PLC cabinet safety type terminal integrated test tool. BACKGROUND

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

[0003] At present, PLC testing mainly relies on manual operation, and the process is complex and prone to errors. First, the technician needs to manually set the test program according to the specific configuration of the PLC cabinet to be tested. This process usually requires a deep 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 large number of PLC modules and complex configurations, the technician not only needs to spend a lot of time, but also is prone to errors in setting the test program due to oversight.

[0004] After the test program is set, the tester also needs to manually connect the test program with each PLC module according to the requirements of the program. This process is extremely challenging due to its complexity, resulting in a low fault tolerance rate. Any mistake can lead to connection errors or omissions, 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, increasing labor costs and operation time. At the same time, due to the large number of manual operations in the testing process, any non-standard operation can cause system failure, further reducing the reliability of the test.

[0067] The PLC cabinet insurance type terminal integrated test tool of the embodiment solves the problems of low efficiency, high error rate and increased test cost in the prior art through a plurality of structural optimizations, and provides a more efficient, stable and flexible test operation scheme. The scheme improves the overall performance through a series of carefully designed structures and components, adapts to various complex test environments, and enhances the ease of operation, test accuracy and maintenance convenience of the equipment.

[0068] First, the shell of a PLC cabinet insurance type terminal integrated test tool adopts a cuboid structure, and one of the side walls with the smallest surface area is provided with a through hole for accommodating the contact 4.

The design of the cylindrical contact 4 further increases the contact area, ensuring accurate transmission of signals, and providing a stable operation experience even in high-frequency testing scenarios.

[0069] The parallel and staggered arrangement of the subterminal one and the subterminal two is one of the core innovations of the embodiment. By staggering the terminals in space, not only is the mutual interference between terminal groups reduced, but also the space utilization and the intuitiveness of operation are improved. This layout design greatly simplifies the wiring and operation process, reduces the risk of operation 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 misconnection, improves the safety and accuracy of testing, and provides more flexibility for system expansion, allowing more terminal groups to be used simultaneously in limited space.

[0070] The recess and fixing groove provided in the shell significantly improve the convenience of installation and disassembly of the device through cooperation with the back clip. The back clip is designed as a cuboid structure and has a protrusion at one end near the safety terminal to enhance the firmness of the connection.

The modular connection method of the plug and the terminal group not only simplifies the wiring process, ensures stable transmission of test signals, but also enhances the adaptability of the system in complex test scenarios. Users can quickly replace the plug and terminal group according to different testing needs, greatly improving operational efficiency and reducing signal interference and transmission loss.

[0073] Finally, the safety PLC test cabinet of the present embodiment integrates multiple PLC cabinet safety terminal integrated test tools and plugs, supporting simultaneous testing of multiple PLC devices. The cabinet provides fixed points for various test equipment, and operators can flexibly deploy and replace test components according to actual needs.

Especially in large-scale testing scenarios, the modular expansion design of the cabinet allows it to quickly adapt to new testing needs, significantly improving overall testing efficiency.

[0074] Through the optimization and implementation of the above multiple designs, the embodiment not only effectively solves the problems of low test efficiency, high error rate and the like in the prior art, but also further improves the operation convenience, test precision, flexibility and scalability of the system of the equipment. In future test system upgrading or function expansion, the scheme has good adaptability and can be adjusted and optimized according to different test requirements, thereby showing significant technical advantages.
