Description

Technical Field

[0001] This invention relates to the field of detection technology, and more particularly to a USB interface detection device that can be inserted at an angle. Background Technology

[0002] The plug-in / plug-out life tester in a USB interface testing device is a device specifically designed to evaluate the durability of USB interfaces. It simulates high-frequency mechanical plugging and unplugging actions (such as thousands to hundreds of thousands of times) to test whether key parameters such as contact resistance, signal stability, and physical structure wear of the interface meet the standards after repeated insertion / removal. This quantifies its actual service life and ensures its reliability for long-term use in consumer electronics, automotive electronics, and other fields.

[0003] Traditional insertion and removal tests typically use a vertical operation, but in actual use, there may be situations where the insertion is tilted. Tilted insertion may lead to uneven distribution of contact pressure or additional mechanical stress. Traditional equipment cannot effectively assess the degradation of the USB interface's insertion and removal life in such scenarios, lacking the limitation of a single angle in real-world usage scenarios. Summary of the Invention

[0004] To overcome the shortcomings of traditional vertical insertion and removal testing equipment that cannot reproduce the scenario of tilted insertion of USB interface, the present invention provides a tiltable USB interface testing device.

[0005] A USB interface testing device with a tiltable design includes a testing machine, a fixed fixture fixedly mounted on the testing machine, a USB port provided on the fixed fixture, at least one guide rail fixedly mounted on the testing machine, a movable fixture slidably connected between all the guide rails, an eccentric machine fixedly mounted on the testing machine, the output end of the eccentric machine rotatably connected to the movable fixture, a rotating frame rotatably connected to the movable fixture, an adjusting nut threadedly connected to the movable fixture, the rotating frame rotatably connected to the adjusting nut, a sliding plate slidably connected to the adjusting nut, a torsion spring fixedly mounted between the sliding plate and the rotating frame, a support frame slidably connected to the rotating frame, the support frame being connected to an installation clamp for holding the USB plug via a first spring, and a first screw threadedly connected to the rotating frame for adjusting the height of the USB plug, the first screw being rotatably connected to the support frame.

[0006] As an improvement to the above solution, it also includes locking blocks symmetrically distributed along the mounting fixture, the locking blocks being slidably connected to the mounting fixture, and the support frame having locking slots corresponding to the locking blocks.

[0007] As an improvement to the above solution, the side of the card block closest to the adjacent card slot is set as a spherical surface.

[0008] As an improvement to the above solution, a second spring is fixedly connected between the card block and the mounting fixture.

[0009] As an improvement to the above solution, a second screw is also included, which is threadedly connected to the movable clamp, and a locking rod is fixed to the end of the second screw near the adjusting nut.

[0010] As an improvement to the above solution, the end face of the lever near the adjusting nut is made concave.

[0011] As an improvement to the above scheme, it also includes a finger rod, which is fixedly connected to the adjusting nut, and an arc-shaped scale is fixedly connected to the movable clamp, with the finger rod pointing towards the arc-shaped scale.

[0012] The present invention has the following advantages: This invention, by setting a tiltable rotating frame structure, can adjust the installation angle of the USB port, thereby simulating the tilted plugging and unplugging actions that users may encounter in actual use. This overcomes the shortcomings of traditional vertical plugging and unplugging test equipment that cannot reproduce non-ideal alignment scenarios, making the test conditions closer to the real use environment.

[0013] Because it can simulate the angled insertion state, this invention can effectively detect the performance degradation of USB interfaces under complex mechanical conditions such as uneven contact pressure distribution and lateral stress, and comprehensively evaluate its contact resistance stability, signal integrity and structural wear during repeated insertion and removal, significantly improving the scientificity and reliability of life test.

[0014] This invention allows for continuous adjustment of the tilt angle of the rotating frame by rotating the adjusting nut, and adjusts the plug height using the first screw, enabling multi-angle and multi-position plug-in simulation. It is suitable for durability testing of various USB interfaces, and the equipment is highly versatile and adaptable to different testing needs.

[0015] This invention features a locking block on a support frame and a corresponding locking groove on the mounting fixture. The elasticity of a second spring causes the locking block to engage with the groove, effectively limiting the vertical movement of the mounting fixture during non-plug-in adjustment, thus improving the positioning stability of the USB plug and facilitating alignment and plugging. During plugging, the mounting fixture can cause the locking block to slide against the elastic force of the second spring, achieving adaptive swinging, balancing positioning accuracy and plugging smoothness, and improving the stability and reliability of testing.

[0025] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0026] Example 1: A USB interface detection device with a slanted insertion design, such as... Figures 1-3As shown, the tester includes a tester 1 for USB interface plug-in / plug-out life testing. A fixed fixture 2 is fixedly attached to the top left side of the tester 1. A USB port 201 is provided on the right side of the fixed fixture 2. Two guide rails 3 are fixedly attached to the right side of the tester 1. A movable fixture 4 is slidably connected between all the guide rails 3 in the left-right direction. An eccentric machine 401 is fixedly attached to the right side of the tester 1. The output end of the eccentric machine 401 is rotatably connected to the movable fixture 4. The eccentric machine 401 is used to drive the movable fixture 4 to slide back and forth on the guide rails 3. A rotating frame 5 is rotatably connected to the upper left side of the movable fixture 4. The front left side of the movable fixture 4 is threaded. An adjusting nut 6 is connected, and the rotating frame 5 is rotatably connected to the adjusting nut 6. A sliding plate 601 is slidably connected to the front side of the adjusting nut 6 in the front-back direction. The front end of the rotating frame 5 passes through the middle of the sliding plate 601. A torsion spring 7 is fixed between the sliding plate 601 and the rotating frame 5. A support frame 9 is slidably connected to the lower part of the rotating frame 5 in the up-down direction. The support frame 9 is connected to a mounting clamp 8 through two front and rear first springs 11. The mounting clamp 8 is used to clamp the USB plug 202. A first screw 10 for adjusting the height of the USB plug 202 is threadedly connected to the bottom of the rotating frame 5. The first screw 10 is rotatably connected to the support frame 9.

[0027] First, fix the USB port 201 to be tested in the mounting fixture 8. Then, rotate the adjusting nut 6, which, through the slide plate 601 and torsion spring 7, causes the rotating frame 5 to tilt upwards or downwards. After the rotating frame 5 adjusts the USB port 201 to the tilt angle simulating a tilted insertion through the mounting fixture 8, turn the first screw 10, causing the support frame 9 to move the mounting fixture 8 upwards or downwards relative to the rotating frame 5 through the first spring 11, so that the USB plug 202, after adjusting the height, is aligned with the USB port 201. Next, start the eccentric machine 401, causing the moving fixture 4 to drive the part on it. The entire component moves to the left, allowing the USB plug 202 to be inserted into the USB port 201. During insertion, the USB plug 202 is squeezed by the USB port 201, causing it to swing adaptively. This automatically adjusts and corrects its parallelism and position during insertion, causing the torsion spring 7 and the first spring 11 to deform. Subsequently, the moving clamp 4 drives the entire component on it to move to the right, causing the USB plug 202 to be pulled out of the USB port 201. The torsion spring 7 and the first spring 11 then return to their original positions. This process is repeated to achieve high-frequency simulation of oblique insertion, which can be used to test the durability of the USB interface in such scenarios.

[0028] Example 2: Based on Example 1, such as Figures 4-5 As shown, it also includes a locking block 12 symmetrically distributed along the front and back of the mounting fixture 8. The locking block 12 is slidably connected to the mounting fixture 8. The upper part of the support frame 9 has a locking groove 121 corresponding to the locking block 12. The side of the locking block 12 near the adjacent locking groove 121 is set as a spherical surface. A second spring 13 is fixed between the locking block 12 and the mounting fixture 8.

[0029] To prevent the mounting clamp 8 from wobbling up and down during the non-plugging adjustment phase, which would cause the USB plug 202 to wobble and make it difficult to plug in, the mounting clamp 8 is fixed to the support frame 9 by the locking block 12 and the locking slot 121. During the plugging adjustment phase, when the mounting clamp 8 swings adaptively with the USB plug 202 relative to the support frame 9, the locking block 12 slides towards the side that compresses the second spring 13, which balances positioning accuracy and plugging smoothness, and improves the stability and reliability of the test.

[0030] like Figures 6-7 As shown, it also includes a second screw 14, which is threadedly connected to the movable clamp 4. A locking rod 15 is fixed to the bottom end of the second screw 14. The bottom end face of the locking rod 15 is set as a concave surface 151. Since the adjusting nut 6 is locked by the thread groove after the angle is adjusted, in order to further strengthen the adjusting nut 6, the second screw 14 is tightened, and the second screw 14 then presses the adjusting nut 6 through the concave surface 151 of the locking rod 15 to prevent the adjusting nut 6 from loosening at will during insertion.

[0031] Example 3: Based on Example 2, such as Figure 8 As shown, it also includes a finger rod 16, which is fixedly connected to the adjusting nut 6. An arc-shaped scale 17 is fixedly connected to the movable clamp 4. The finger rod 16 points to the arc-shaped scale 17. When the adjusting nut 6 rotates, it drives the finger rod 16 to rotate. According to the scale value of the arc-shaped scale 17 pointed to by the finger rod 16, the tilt angle of the adjustment can be intuitively understood.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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.
