Description

Technical Field

[0001] This utility model relates to the field of signal detection technology, and in particular to a modular anti-interference test signal generator integrated box. Background Technology

[0002] With the rapid development of industrial automation, communication technology, and electronic equipment manufacturing, the requirements for the anti-interference performance of various devices in complex electromagnetic environments are becoming increasingly stringent. Traditional anti-interference system testing covers conducted immunity and radiated immunity. Conducted immunity testing requires connecting cables to couple with the radio frequency field and interfere with the device under test. Against this backdrop, modular test signal generators have emerged due to their advantages of flexible combination and strong functional expandability. They can meet the diverse testing needs of different industries for the anti-interference performance of equipment.

[0003] The modular anti-interference test signal generator integrated box mainly consists of a signal generation module, an anti-interference module, a control module, and a power supply module. The signal generation module generates test signals of different frequencies and amplitudes. The anti-interference module uses shielding materials and filtering circuits to effectively resist external electromagnetic interference. The control module can realize precise adjustment of signal parameters and system operation control. The power supply module provides stable power to each module. During operation, the control module sets the signal parameters, the signal generation module generates test signals according to the instructions, and the anti-interference module ensures that the signal is not affected by external interference during generation and transmission, ultimately outputting a stable and accurate test signal for testing the anti-interference performance of the device under test.

[0004] Currently available integrated boxes for anti-interference test signal generators often lack cable reinforcement structures during equipment testing, leading to loosening and displacement of the connecting cables between the device under test and the integrated box during the testing process. This results in unstable signal transmission and affects the accuracy and reliability of the test results. To address this issue, a modular integrated box for anti-interference test signal generators is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a modular anti-interference test signal generator integrated box, which aims to improve the problem of the lack of cable reinforcement structure in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular anti-interference test signal generator integrated box includes a housing. A connecting module is slidably connected inside the housing. Multiple interfaces are provided inside the connecting module. Multiple rotating rods are rotatably connected to the outside of the connecting module. Limiting clamps one and two are rotatably connected to the front ends of the two rotating rods, respectively. A fixing block is fixedly connected to the outside of the limiting clamps one. A limiting block one is slidably connected inside the fixing block. A fixing post is fixedly connected to the outside of the limiting clamps two. A rotating rod two is rotatably connected to the outside of the fixing post. A sliding post is fixedly connected inside the rotating rod two. A disassembly / assembly assembly is provided on the outside of the housing.

[0010] As a further description of the above technical solution:

[0011] The outer side of the first limiting block is oblique, and the outer side of the sliding column is in contact with the outer side of the first limiting block;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the equipment is being tested, after the cable of the device under test is connected to the interface, the rotating component drives the limiting clamp to fit the cable. Then, the rotating rod is rotated to make the sliding column press against the limiting block and slide into the fixed block. Subsequently, the limiting block resets due to gravity to limit the sliding column, thereby realizing the stable clamping of the cable by the limiting clamp, ensuring the stable connection between the testing equipment and the device under test, and ensuring the smooth progress of the testing process.

[0024] 2. In this utility model, when the connecting module needs to be maintained or replaced, the pull rod is pulled to make the limiting block slide out of the connecting module, so that the connecting module can be taken out of the housing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 One embodiment of this utility model is a modular anti-interference test signal generator integrated box, which includes a housing 1. The housing 1 serves as the external protective structure of the entire integrated box, providing protection for internal components such as the connection module 2, and preventing them from being affected by external physical damage, dust intrusion, etc. The housing 1 has a sliding connection module 2 inside, which is the key part to realize the signal connection between the device under test and the integrated box. The sliding connection design of the connection module 2 makes it easier to install and disassemble. The connection module 2 has multiple interfaces 3 inside, which can adapt to different types of devices under test cables, providing multiple possibilities for connection and meeting diverse testing needs. The connection module 2 has multiple rotating rods 4 on the outside. The rotating rods 4 can be used to drive the rotation of the limit clamps 5 and 6 to realize the clamping action of the cable. The front ends of the two rotating rods 4 are respectively rotatably connected to the limit clamps 5 and 6. The limit clamps 5 and 6 are key structures for fixing the cable. The rotation connection of the limit clamps 5 and 6 can flexibly adjust their positions to adapt to cables of different thicknesses and shapes. The limit clamp 5 is fixedly connected to the outside of the fixing block 12. The fixing block 12 provides sliding space for the limit block 10 and plays a supporting and connecting role in the entire cable fixing process.

[0033] A limiting block 10 is slidably connected inside the fixed block 12. The sliding of the limiting block 10 inside the fixed block 12 restricts the position of the sliding post 9, thereby ensuring the stable clamping of the cable by the limiting clamp 6 and the limiting clamp 5. A fixed post 7 is fixedly connected to the outside of the limiting clamp 6. A rotating rod 8 is rotatably connected to the outside of the fixed post 7. A sliding post 9 is fixedly connected inside the rotating rod 8. The fixed post 7 provides a fulcrum for the rotation of the rotating rod 8, allowing the rotating rod 8 to rotate around it. The rotation of the rotating rod 8 can drive the movement of the sliding post 9, thereby achieving the squeezing of the limiting block 10 and the fixing of the cable. Under the drive of the rotating rod 8, the sliding post 9 can slide inside the fixed block 12 to achieve the squeezing action of the limiting block 10. A disassembly assembly is provided on the outside of the housing 1. The existence of the disassembly assembly makes the installation and disassembly of the connecting module 2 more convenient and quick, improving equipment maintenance. To improve the efficiency of cable protection, the fixed block 12 has a groove on its outside, and the sliding column 9 is slidably connected to the inside of the groove. The groove provides guidance and restriction for the sliding column 9, ensuring that it moves along a predetermined trajectory. The outer side of the limiting block 10 is inclined, and the outer side of the sliding column 9 contacts the outer side of the limiting block 10. This inclined design allows the sliding column 9 to effectively squeeze the limiting block 10 when sliding, making it slide inside the fixed block 12. The top of the limiting block 10 is fixedly connected to a control handle 11, which allows the operator to manually operate the limiting block 10. In special cases, if it is necessary to manually adjust the position of the limiting block 10, it can be operated through the control handle 11. The outer side of the limiting clamp 5 is arc-shaped. The arc design can better fit the shape of the cable, increase the contact area with the cable, thereby improving the fixing effect of the cable and making the connection between the tested equipment and the detection equipment more stable.

[0034] Reference Figure 1 , Figure 2 and Figure 4The disassembly and assembly assembly includes a fixing box 13, which is fixedly connected to the outside of the housing 1 as part of the assembly. The fixing box 13 is externally fixed to the outside of the housing 1. A second limiting block 16 is slidably connected inside the fixing box 13. The sliding of the second limiting block 16 inside the fixing box 13 allows for the restriction and release of the position of the connecting module 2, making it a key component for the quick disassembly and assembly of the connecting module 2. A telescopic column 14 is fixedly connected to the top of the second limiting block 16. The telescopic column 14 guides and supports the second limiting block 16 during sliding and, in conjunction with a spring 15, achieves automatic reset of the second limiting block 16. A spring 15 is sleeved on the outside of the telescopic column 14. The spring 15 is a key component for the automatic reset of the second limiting block 16. When the external force is removed, the elastic force of the spring 15 pushes the second limiting block 16 back to its original position. A pull rod 17 is fixedly connected to the front end of the second limiting block 16. 7. The limiting block 16 is designed for easy manual operation by staff. By pulling the lever 17, the limiting block 16 can slide inside the fixed box 13. The external sliding connection of the limiting block 16 is to the inside of the connecting module 2. When the limiting block 16 slides into the connecting module 2, it can limit the position of the connecting module 2, making it securely installed inside the housing 1. The top of the telescopic column 14 is fixedly connected to the inside of the fixed box 13, ensuring the stability and reliability of the telescopic column 14. One end of the spring 15 is fixedly connected to the inside of the fixed box 13, and the other end is fixedly connected to the top of the limiting block 16. This connection method allows the spring 15 to effectively apply force to the limiting block 16. The front end of the fixed box 13 has a slot, and the external sliding connection of the lever 17 is to the inside of the slot. The slot provides guidance and restriction for the sliding of the lever 17, ensuring that the lever 17 can accurately drive the limiting block 16 to slide.

[0035] Working principle: When the operator needs to test the device under test, the cable of the device under test is connected to the interface 3. At this time, the operator can fix the cable and rotate the first rotating rod 4 to make the first limiting clamp 5 and the second limiting clamp 6 tightly fit against the outside of the cable. Then, rotate the second rotating rod 8 to make the outside of the sliding column 9 slide inside the fixed block 12. When the sliding column 9 slides, it will squeeze the first limiting block 10, thereby making the first limiting block 10 slide inside the fixed block 12. This allows the sliding column 9 to slide completely into the fixed block 12. Then, the first limiting block 10 will automatically slide inside the fixed block 12 due to gravity, sliding back to its original position, thereby limiting the position of the sliding column 9. The second limiting clamp 6 and the first limiting clamp 5 clamp and limit the cable, thereby making the connection between the device under test and the testing equipment stable and ensuring the normal operation of the testing process.

[0036] When the operator needs to maintain or replace the connecting module 2, pulling the lever 17 causes the limiting block 16 to slide inside the fixing box 13, thus removing the restriction on the position of the connecting module 2. The operator can then remove the entire connecting module 2 from the housing 1 for easy replacement and cleaning. For installation, first pull the lever 17 to slide the limiting block 16 into the fixing box 13. Then, the outside of the connecting module 2 can be slid into the housing 1. Once the outside of the connecting module 2 has slid to the designated position, releasing the lever 17 will cause the spring 15 to automatically push the limiting block 16 to slide inside the fixing box 13, thus allowing the limiting block 16 to slide into the connecting module 2, completing the installation of the connecting module 2. This quick disassembly and assembly of the connecting module 2 facilitates replacement and maintenance, reduces disassembly time, and improves efficiency.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
