[0002] With the widespread application of electrical equipment in industrial production and daily life, problems such as equipment aging and circuit faults occur frequently. Traditional manual troubleshooting is inefficient and inaccurate. Against this backdrop, electrical equipment fault detection equipment has emerged. This type of equipment is mainly used in manufacturing, power industry, rail transportation, construction industry, and household appliance repair.

[0003] Electrical equipment fault detection equipment typically consists of a functional detection module, a display unit, operating components, and a housing. Some simpler devices employ a purely hardware structure without automation programs, achieving multi-functional detection through mechanical switching. Its main function is to quickly identify faults in electrical equipment such as short circuits, open circuits, overvoltages, undervoltages, and poor grounding, accurately pinpointing the problem location, reducing manual troubleshooting time, minimizing equipment downtime losses, and ensuring the safe and stable operation of electrical systems.

[0004] Currently available electrical equipment fault detection equipment is bulky and inconvenient to carry when workers need to climb to heights. The detection lines and equipment are often fixed with bolts, making operation complicated. Therefore, this paper proposes an electrical equipment fault detection device to solve the above problems.

[0032] Reference Figures 2-4This utility model provides an embodiment of an electrical equipment fault detection device, including a housing 1. The housing 1 serves to support internal components. Two slots 2 are formed at the top of the housing 1, and two circular grooves 3 are formed on the inner wall of each slot 2. A cylinder 5 is fixedly connected inside each circular groove 3. A claw 6 is fixedly connected to one end of each cylinder 5, and a spring 4 is fixedly connected to the other end. A limiting ring 7 is fixedly connected to the outside of the claw 6, and a plug 8 is slidably connected to the outside of the limiting ring 7. A limiting groove 9 is formed on the outside of the plug 8. When the plug 8 is inserted into the slot 2, it presses against the claw 6, thereby compressing the spring 4. Once the limiting ring 7 is engaged in the limiting groove 9, the plug 8 is fixed. After use, the plug 8 can be pulled out. (See reference...) Figures 5-7 The bottom of the box body 1 has two locking grooves 13, and the inner wall of the locking groove 13 has a square groove 14. The locking tongue 15 is slidably connected inside the square groove 14. The locking tongue 15 is fixedly connected to the outside of the locking tongue 15. The bottom of the box body 1 has two sliding grooves 18, and the locking tongue 15 is fixedly connected to the outside of the locking tongue 15. Pulling the handle 17 causes the locking tongue 15 to slide into the square groove 14. Releasing the handle 17 resets the locking tongue 15.

[0033] Reference Figure 1 The plug 8 is externally fixedly connected to a wire 10. The end of the wire 10 away from the plug 8 is fixedly connected to a clamp 11 and a test pen 12. During use, the device can quickly switch between using the clamp 11 and the test pen 12.

[0034] Reference Figures 6-8 The locking tongue 15 is fitted with retaining rings 19, and a shoulder strap 20 is fixedly connected between two retaining rings 19. By engaging the retaining rings 19 with the locking tongue 15, the device can be transformed from a handheld device into a backpack device in a very short time, making it convenient to carry. (Refer to...) Figures 2-4 The end of spring 4 away from cylinder 5 is fixedly connected to the inner wall of the circular groove 3. The limiting ring 7 and the limiting groove 9 engage, making the plug 8 more stable after being inserted into the slot 2.

[0035] Reference Figures 5-7 The handle 17 is slidably connected to the inner wall of the slide groove 18, the end of the locking tongue 15 away from the spring 16 abuts against the inner wall of the locking groove 13, and the end of the spring 16 away from the locking tongue 15 is fixedly connected to the inner wall of the square groove 14 to prevent the retaining ring 19 on the outside of the locking tongue 15 from falling off.

[0038] Working principle: Pulling handle 17 allows it to slide within the groove 18, causing the locking tongue 15 to slide into the square groove 14 and compressing spring 16. At this point, the retaining ring 19 is engaged with the locking tongue 15. Releasing handle 17 causes spring 16 to return to its original position, pushing the locking tongue 15 against the inner wall of the locking groove 13, thus securing the retaining ring 19. The shoulder strap 20 switches the device to a backpack configuration. To remove the shoulder strap 20, repeat the above steps to return to the handheld position. Before testing, connect the testing components: Insert plug 8 into the slot 2 at the top of the housing 1. During insertion, plug 8 presses against the claw 6 at one end of the cylinder 5 within the circular groove 3, compressing spring 4 at the other end of the cylinder 5 until the limiting ring 7 outside the claw 6 engages with the limiting groove 9 of plug 8. Spring 4 then returns to its original position, securing plug 8. After use, pull plug 8 out; spring 4 compresses again, disengaging the limiting ring 7 from the limiting groove 9. Plug 8 is connected to clamp 11 and test pen 12 via wire 10, allowing for quick switching according to testing needs. The detection mode is switched by the knob 26 on the top of the box 1, and the function is selected by the button 25 and the button 23. The detection parameters are displayed on the display screen 1 21 and the display screen 22. The indicator light 24 provides real-time feedback on the equipment's operating status, thereby completing the detection of electrical equipment faults.
