Description

Technical Field

[0001] The utility model relates to the technical field of current testing, in particular to a device for testing leakage current of a device. Background Art

[0002] A device leakage current tester is a specialized device used to detect leakage current in electronic devices. It typically consists of a high-precision ammeter, a voltage source, and a test fixture. During the test, the device under test is properly connected to the tester, and a specific voltage is applied to measure the tiny current flowing through the device to determine whether the device's leakage current is within a specified range. This device features high precision and excellent stability, and can accurately detect potential leakage problems in devices, providing an important basis for quality control and reliability assessment of electronic products. It is widely used in industries such as electronics manufacturing and semiconductors to ensure product performance and safety. Device leakage current testers typically require the following technologies:

[0003] 1. Able to accurately measure tiny leakage current to ensure the accuracy of test results;

[0004] 2. Provide stable power supply to ensure consistency of test conditions;

[0005] 3. Prevent the influence of external electromagnetic interference on test results;

[0006] 4. Realize the automation of the test process to improve test efficiency and repeatability;

[0007] 5. Analyze and process the test data, extract useful information, and judge the performance of the device.

[0008] Currently, manufacturers use a variety of equipment and methods to achieve the functions of device leakage current test equipment. For high-precision measurement, high-precision measuring instruments such as ammeters and voltmeters are used, as well as specialized leakage current test equipment. For stable power supply, devices such as voltage-regulated power supplies and constant current sources are used to ensure the stability of power output. For good shielding, shielded boxes and shielded cables are used to reduce external electromagnetic interference. For automated control, programmable logic controllers (PLCs) and computers are used to achieve automated testing. For data analysis and processing, data analysis software is used to process and analyze test data.

[0009] However, the above method has a prominent hardware structure problem. The overall structure of the device leakage current test device is relatively complex, and the volume and weight are relatively large, making it difficult to move easily. When on-site testing or mobile office work is required, the device cannot be easily brought to the designated location, which limits the flexibility of the work. In response to this problem, this application proposes a solution and designs a portable mechanism. Workers can easily carry the device to different work locations. Whether it is on-site testing, outdoor maintenance or a temporary workplace, the device can be used at any time to perform leakage current testing, thereby improving the flexibility of the device leakage current test device.

The four threaded grooves 21 correspond to the positions of the four bolts 15, and each bolt 15 is threadedly sleeved with the corresponding bracket plate 12. When the device body 11 needs to be moved, the long block 20 in the bracket plate 12 is moved out, and the telescopic blocks 23 in the two long blocks 20 are moved out. At this time, the threaded rod 26 corresponds to the handle 24, and the handle 24 is rotated. The handle 24 is threadedly sleeved with the threaded rod 26, so that the handle 24 is connected to the threaded rod 26. At this time, the staff directly holds the handle 24 to achieve the purpose of picking up the device body 11, which improves the staff's flexibility when carrying.

[0036] A rectangular groove 16 is provided at the opposite end of the two bracket plates 12, and a connecting column 19 is provided inside the two rectangular grooves 16. The upper and lower ends of the two connecting columns 19 are fixedly connected to the inner wall of the bracket plate 12. A long block 20 is provided in the two rectangular grooves 16, and the two long blocks 20 are rotatably connected to the corresponding connecting columns 19. The interior of the two long blocks 20 is movably sleeved with a telescopic block 23, and both ends of the two telescopic blocks 23 are fixedly connected to a limit block 25. When the telescopic block 23 moves in the long block 20, the limit block 25 will also move along the rectangular groove three 22.

The handle 24 is threadedly sleeved with the threaded rod 26, so that the handle 24 is connected to the threaded rod 26. At this time, the staff directly grasps the handle 24 to achieve the purpose of taking the device body 11, which improves the staff's flexibility when carrying. When the telescopic block 23 moves in the long block 20, the limit block 25 will also move along the rectangular groove 3 22. When the telescopic block 23 moves to a certain distance, the limit block 25 will press against the inner wall of the long block 20, so that the telescopic block 23 can move to a certain distance. The retractable block 23 cannot move further, avoiding the problem of the telescopic block 23 being separated from the long block 20 due to excessive movement of the telescopic block 23. When the device body 11 needs to be placed, the staff lifts the device body 11. When the device body 11 moves to the upper end of the bolt 15, the bolt 15 is rotated. The rotated bolt 15 will pass through the rectangular slot 2 17. At this time, the device body 11 is loosened, and the two lifting plates 18 will resist the corresponding bolts 15, so that the lifting plates 18 and the device body 11 cannot descend. At this time, the device body 11 is in a higher position, so the staff does not need to bend down to observe the data on the device body 11, which is convenient for the staff to observe the data on the device body 11.
