Description

Technical Field

[0001] This utility model relates to the field of resistance performance testing technology, and more specifically, to an automated resistance performance testing device. Background Technology

[0002] Resistors and other electronic components are widely used in electronic devices, and their performance directly affects the overall performance and reliability of the equipment. For example, in electronic products such as mobile phones and computers, resistors are used for critical tasks such as limiting current, voltage division, and impedance matching. Their quality and performance are related to the stability and lifespan of the product. As electronic devices develop towards miniaturization and high performance, higher requirements are placed on the accuracy, efficiency, and automation of resistor performance testing. During production, robotic arms are usually used to automatically insert resistors into sockets for rapid resistance performance testing, improving work efficiency and accuracy. However, the sockets on the device are exposed, and dust floating in the air can enter the sockets during use and adhere to the surface of the socket spring pins. Over time, the dust can form a thick insulating layer, significantly increasing the contact resistance and causing fluctuations in the detection current, thus affecting the test results. In view of this, we propose an automated resistance performance testing device. Utility Model Content

[0003] The purpose of this invention is to provide an automated resistance performance testing device to solve the problem mentioned in the background art where dust falls into the slot and accumulates, affecting the accuracy of the testing device in detecting resistance performance.

[0004] To achieve the above objectives, this utility model provides an automated resistance performance testing device, including a testing device panel. A slot is formed on the upper surface of the testing device panel. A protective device is provided on the upper side of the testing device panel. The protective device includes a fixing block, which is fixedly installed on the upper side of the testing device panel. An inner groove is formed on the lower surface of the fixing block. A sliding plate is slidably disposed inside the inner groove. A protective plate is fixedly connected to one side of the sliding plate. One side of the protective plate passes through the fixing block and extends outwards. A through groove is formed on the protective plate. An elastic connector is provided on the side of the sliding plate away from the protective plate. The elastic connector is used to apply a pushing force to the sliding plate towards the side closer to the protective plate.

[0005] By adopting the above solution, the elastic force applied to the sliding plate by the elastic connector pushes the protective plate to slide, so that the protective plate covers the slot and prevents dust from entering the slot.

[0006] As a further improvement to this technical solution, the elastic connector includes a first connecting rod fixedly installed inside the fixed block, a second connecting rod slidably disposed inside the first connecting rod, one end of the second connecting rod extending out of the first connecting rod and fixedly connected to the sliding plate, and the other end of the second connecting rod being fixedly connected to a spring located inside the first connecting rod.

[0007] By adopting the above solution, when the plug is unplugged, the elastic thrust applied by the spring to the second connecting rod causes the second connecting rod to push the sliding plate to slide, thereby allowing the protective plate to quickly return to its original position.

[0008] As a further improvement to this technical solution, a limiting groove is formed on the inner surface of the first connecting rod, and a limiting block is slidably arranged inside the limiting groove. The limiting block is fixedly installed on the outer side of the second connecting rod near the spring.

[0009] By adopting the above scheme, when the second connecting rod slides, the position of the second connecting rod is limited by the sliding of the limiting block inside the limiting groove.

[0010] As a further improvement to this technical solution, guide grooves are provided on both sides of the inner groove, and guide blocks are slidably arranged inside the guide grooves, with the guide blocks fixedly installed on the sliding plate.

[0011] By adopting the above scheme, when the sliding plate slides inside the inner groove, the sliding plate is guided by the sliding of the guide block inside the guide groove, thus preventing the sliding plate from getting stuck due to uneven force.

[0012] As a further improvement to this technical solution, a groove is provided on the upper surface of the protective plate, and a slider is slidably arranged inside the groove, and the slider is fixedly installed on the fixed block.

[0013] By adopting the above solution, when the protective plate slides, the sliding block inside the groove guides the protective plate, preventing it from sliding sideways.

[0014] As a further improvement to this technical solution, a rubber pad is fixedly installed on the upper side of the protective plate and is provided on the sliding plate. When the sliding plate is reset, the rubber pad protects the sliding plate.

[0015] By adopting the above scheme, when the sliding plate is reset, the rubber pad buffers the sliding plate, thus protecting the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this automated resistance performance testing device, the elastic thrust applied by the spring to the second connecting rod causes the second connecting rod to push the sliding plate inside the inner groove, thereby enabling the protective plate to quickly reset and cover the slot, preventing dust accumulation due to long-term exposure of the slot, which would affect the accuracy of the resistance performance test results.

[0026] Example 1

[0027] Please see Figures 1-3 As shown, this embodiment provides an automated resistance performance testing device, including a testing device panel 1. A slot 3 is formed on the upper surface of the testing device panel 1. A protective device 2 is provided on the upper side of the testing device panel 1. The protective device 2 includes a fixing block 21, which is fixedly installed on the upper side of the testing device panel 1 by fixing bolts. An inner groove 23 is formed on the lower surface of the fixing block 21. A sliding plate 24 is slidably disposed inside the inner groove 23. A protective plate 25 is fixedly connected to one side of the sliding plate 24. One side of the protective plate 25 passes through the fixing block 21 and extends outward. A through groove 26 is formed on the protective plate 25. An elastic connector is provided on the side of the sliding plate 24 away from the protective plate 25. The elastic connector is used to support the sliding plate 24. A pushing force is applied to the side closer to the protective plate 25. When the resistance detection ends and the plug is pulled out of the slot 3, the elastic force applied to the sliding plate 24 through the elastic connector pushes the sliding plate 24 to slide inside the inner groove 23, so that the protective plate 25 quickly resets and completely covers the slot 3, preventing dust from falling into the slot 3 and affecting the accuracy of the resistance detection. The upper side of the protective plate 25 is provided with a rubber pad 233 fixedly installed on the sliding plate 24. When the sliding plate 24 quickly resets and contacts the fixing block 21, the rubber pad 233 buffers the impact force generated when the sliding plate 24 slides, preventing the device from being damaged by the impact of the sliding plate 24 after long-term use, thus protecting the device and extending its service life.

[0028] Please see Figure 2 and Figure 4 As shown, the elastic connector includes a first connecting rod 27 fixedly installed inside the fixing block 21, a second connecting rod 28 slidably disposed inside the first connecting rod 27, one end of the second connecting rod 28 extending out of the first connecting rod 27 and fixedly connected to the sliding plate 24, and the other end of the second connecting rod 28 fixedly connected to a spring 29 located inside the first connecting rod 27. When the plug is pulled out of the slot 3, the elastic thrust applied to the second connecting rod 28 by the spring 29 causes the second connecting rod 28 to slide inside the first connecting rod 27, thereby causing the second connecting rod 28 to push the sliding plate 24 to slide. The inner surface of the first connecting rod 27 has a limiting groove 211, and a limiting block 222 is slidably disposed inside the limiting groove 211. The limiting block 222 is fixedly installed on the outer side of the second connecting rod 28 near the spring 29. When the second connecting rod 28 slides inside the first connecting rod 27, the sliding of the limiting block 222 inside the limiting groove 211 limits the position of the second connecting rod 28, preventing the second connecting rod 28 from slipping.

[0029] Please see Figures 2-4As shown, guide grooves 244 are provided on both sides of the inner groove 23. Guide blocks 255 are slidably arranged inside the guide grooves 244. The guide blocks 255 are fixedly installed on the sliding plate 24. When the sliding plate 24 slides inside the inner groove 23, the sliding of the guide blocks 255 inside the guide grooves 244 guides the sliding plate 24, increases the uniformity of the force on the sliding plate 24, and avoids the sliding plate 24 from getting stuck due to uneven force during the sliding process, making the device more stable. At the same time, a sliding groove 266 is provided on the upper surface of the protective plate 25. A slider 277 is slidably arranged inside the sliding groove 266. The slider 277 is fixedly installed on the fixing block 21. When the protective plate 25 slides, the sliding of the slider 277 inside the sliding groove 266 guides the protective plate 25, avoids the protective plate 25 from sliding sideways, and ensures the protective effect of the protective plate 25.

[0030] In practical use, when resistance performance testing is required, the plug is inserted into the slot 3 and tested by inserting it into the through slot 26 and pushing the protective plate 25 to slide. When the plug is pulled out, the elastic force applied by the spring 29 to the second connecting rod 28 pushes the second connecting rod 28 to slide inside the first connecting rod 27, and the second connecting rod 28 pushes the sliding plate 24 to slide inside the inner slot 23, so that the protective plate 25 quickly resets and covers the slot 3, preventing dust from the air from falling into the slot 3 and accumulating after long-term use, thus protecting the testing device.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
