Description

Technical Field

[0001] This utility model relates to a test fixture, specifically, to an HDMI interface continuity performance test fixture. Background Technology

[0002] HDMI, or High-Definition Multimedia Interface, is a digital video / audio interface technology. It's a dedicated digital interface suitable for image transmission, capable of simultaneously transmitting audio and video signals. To ensure proper signal transmission, HDMI interfaces require continuity testing after production. Existing test fixtures typically use elastic contact pins to connect to the HDMI interface. However, these pins gradually lose elasticity over time, leading to poor contact between the pin tip and the HDMI interface. Furthermore, the contact pins in existing test fixtures are usually exposed, allowing dust to accumulate around them over extended periods. This can disrupt the connection between the pin and the HDMI interface, affecting the accuracy of test results. Excessive dust accumulation also poses a short-circuit risk. Therefore, we propose an HDMI interface continuity performance test fixture. Utility Model Content

[0003] The purpose of this invention is to provide an HDMI interface continuity performance test fixture to solve the problems mentioned in the background art.

[0004] The elasticity of the existing test fixture's elastic contact pins gradually decreases with prolonged use, and excessive dust accumulation near the contact pins can affect the accuracy of test results.

[0005] To achieve the above objectives, this utility model provides an HDMI interface continuity performance testing frame, including a base. A testing machine is fixedly mounted on the upper side of the base. The testing machine has multiple connection ports of different shapes on one side. Each of the multiple connection ports has a partition component inside. A testing component is mounted on one side of the partition component. The partition component includes two partitions, which are symmetrically and slidably disposed inside the connection ports. A first tooth block is disposed on the upper side of the partition, which is slidably disposed inside the connection ports. A protrusion is fixedly mounted on the end of the first tooth block away from the partition. A driving component is disposed in the middle position on the upper side of the two partitions.

[0006] Two partitions enclose the test component inside the connection port. When the protrusion slides, it drives the first tooth block to slide, which in turn drives the drive component to drive the two partitions to slide.

[0007] As a further improvement to this technical solution, the drive assembly includes a first gear, which is rotatably disposed inside the connection port. The first gear meshes with a first gear block, and both the first gear block and the first gear are perpendicular to the two partitions.

[0008] During the process of inserting the HDMI interface into the connector, the HDMI interface comes into contact with the protrusion and pushes the protrusion, which in turn causes the first gear to slide. As the first gear slides, it drives the first gear to rotate.

[0009] As a further improvement to this technical solution, a lead screw is fixedly connected to both sides of the first gear. The threads of the two lead screws are opposite. The end of the lead screw away from the first gear is rotatably connected to the inner wall of the testing machine. The two lead screws are respectively rotatably inserted into the upper side of the two partitions. A compression spring is fixedly installed at the end of the first gear block away from the protrusion. The end of the compression spring away from the first gear block is fixedly connected to the inner wall of the testing machine.

[0010] When gear number one rotates, it drives two lead screws to rotate. At the same time, the two lead screws drive two partitions to slide. During the process of unplugging the HDMI interface, the compression spring pushes the gear number one and drives gear number one to rotate in the opposite direction, while also driving the two partitions to slide in the opposite direction.

[0011] As a further improvement to this technical solution, a second tooth block is fixedly provided on the lower side of one of the partitions, and a second gear is meshed on the lower side of the second tooth block. The second gear is rotatably disposed inside the testing machine, and a second lead screw is fixedly provided on one side of the second gear. The end of the second lead screw away from the second gear is rotatably connected to the inner wall of the testing machine.

[0012] When the partition slides, it causes the second gear block to slide as well, and at the same time, the second gear block rotates, which in turn drives the second lead screw to rotate.

[0013] As a further improvement to this technical solution, the test component includes a slider, which is slidably disposed inside the connection port. Multiple slide rails for limiting the slider are fixedly disposed inside the connection port, and the second lead screw is rotatably inserted through the lower side of the slider.

[0014] When the No. 2 lead screw rotates, it drives the slider to slide along the direction of the slide rail inside the connection port.

[0015] As a further improvement to this technical solution, a plurality of contact pins are fixedly provided on the side of the slider near the separating component, and a tension spring is fixedly provided on the side of the slider away from the contact pins. The end of the tension spring away from the slider is fixedly connected to the inner wall of the testing machine.

[0016] As the slider slides, it causes multiple contact pins to slide towards the side closer to the partition. After the contact pins come into contact with the HDMI interface, they are tested. When the HDMI interface is unplugged, the tension spring pulls the slider.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. In this HDMI interface continuity test fixture, when the user inserts the HDMI interface into the connection port on one side of the test machine, the HDMI interface pushes the protrusion into the connection port, causing the first toothed block to slide into the connection port. The first toothed block drives the first gear and two first lead screws to rotate, causing the two partitions to move to the side away from each other. While the partitions are moving, they drive the second gear to rotate, which in turn drives the second lead screw to rotate. The second lead screw drives the slider to slide closer to the partition assembly and gradually make contact with the HDMI interface. When the HDMI interface is connected, the device automatically pushes out the contact pin and makes contact with the HDMI interface, preventing the device from losing elasticity over time and causing poor contact between the contact pin and the HDMI interface.

[0019] 2. In this HDMI interface continuity performance test fixture, after the test is completed, the user unplugs the HDMI interface. At the same time, the compression spring pushes out the first gear block, which drives the first gear and the first lead screw to rotate in opposite directions. The first lead screw drives the two partitions to slide towards each other, and drives the second gear and the second lead screw to rotate in opposite directions. The second lead screw drives the slider to slide away from the partition component. After the two partitions move to fit together, they protect the contact pins and prevent excessive dust accumulation near the contact pins due to prolonged use of the device, thus improving the test accuracy of the device.

[0031] Example 1

[0032] Please see Figures 1-3 As shown, this embodiment provides an HDMI interface continuity performance test fixture, including a base 1. A tester 2 is fixedly mounted on the upper side of the base 1. The tester 2 has multiple connection ports of different shapes on one side. When using the device, the user first inserts the HDMI interface into the corresponding connection port on the side of the tester 2. Each of the multiple connection ports is provided with a partition component 3. The partition component 3 includes two partitions 31. The two partitions 31 are symmetrically slidably disposed inside the connection port. A test component 4 is provided on one side of the partition component 3. The sides of the two partitions 31 that are close to each other are initially attached to each other, enclosing the test component 4 inside the connection port.

[0033] Please see Figures 2-4As shown, a first toothed block 32 is provided on the upper side of the partition 31. The first toothed block 32 is slidably disposed inside the connection port. A protrusion 33 is fixedly provided at the end of the first toothed block 32 away from the partition 31. When the HDMI interface enters the connection port, it contacts the protrusion 33 and pushes the protrusion 33 inward, thereby driving the first toothed block 32 to slide. A drive assembly 34 is provided at the middle position on the upper side of the two partitions 31. The drive assembly 34 includes a first gear 341, which is rotatably disposed inside the connection port. The first gear 341 meshes with the first toothed block 32. Both gear 32 and gear 341 are perpendicular to the two partitions 31. While sliding, gear 32 drives gear 341 to rotate. Both sides of gear 341 are fixedly connected to lead screws 342. The threads of the two lead screws 342 are opposite. The end of the lead screw 342 away from gear 341 is rotatably connected to the inner wall of the testing machine 2. The two lead screws 342 are respectively rotatably inserted into the upper side of the two partitions 31. When gear 341 rotates, it drives the two lead screws 342 to rotate and causes the two partitions 31 to slide to the side away from each other.

[0034] Please see Figure 3 As shown, a second toothed block 36 is fixedly installed on the lower side of a partition 31. A second gear 37 is meshed with the lower side of the second toothed block 36. The second gear 37 is rotatably installed inside the testing machine 2. When the partition 31 slides, it drives the second toothed block 36 to move. At the same time, the second toothed block 36 drives the second gear 37 to rotate. A second lead screw 38 is fixedly installed on one side of the second gear 37. The end of the second lead screw 38 away from the second gear 37 is rotatably connected to the inner wall of the testing machine 2. When the second gear 37 rotates, it drives the second lead screw 38 to rotate.

[0035] Please see Figures 1-5As shown, the test assembly 4 includes a slider 41, which is slidably disposed inside the connection port. Multiple slide rails for limiting the slider 41 are fixedly disposed inside the connection port. A second lead screw 38 rotatably passes through the lower side of the slider 41. When the second lead screw 38 rotates, it drives the slider 41 to slide towards the side closer to the partition 31. Multiple contact pins 42 are fixedly disposed on the side of the slider 41 closer to the separating assembly 3. A baffle 5 is disposed on the side of the separating assembly 3 away from the test assembly 4. The baffle 5 is fixedly disposed inside the connection port and has openings for contacting the multiple contact pins 42. The slider 41 moves along the small hole corresponding to position 2, causing the contact pin 42 to gradually approach the baffle 5. After passing through the small hole in the baffle 5, the contact pin 42 contacts the HDMI interface and tests the HDMI interface. A control panel 6 is set on one side of the test machine 2. The control panel 6 is fixedly set on the upper side of the base 1. A signal line is fixedly connected between the test machine 2 and the control panel 6. A signal transmission device is fixedly set inside the test machine 2. After the test results are transmitted to the control panel 6 through the signal line, the user can analyze and store the results by operating the control panel 6.

[0036] Please see Figures 2-5 As shown, a compression spring 35 is fixedly installed at the end of the first tooth block 32 away from the protrusion 33. The end of the compression spring 35 away from the first tooth block 32 is fixedly connected to the inner wall of the testing machine 2. After the test is completed, the user unplugs the HDMI interface. At the same time, the compression spring 35 pushes the first tooth block 32, causing the first gear 341 to rotate in the opposite direction. The first gear 341 drives the two first lead screws 342 to rotate in the opposite direction, and causes the two partitions 31 to slide towards each other until the two partitions 31 are close to each other. The sides that are closest to each other come into contact again. While the partition 31 slides, it drives the second tooth block 36 to slide and drives the second gear 37 to rotate in the opposite direction. The second gear 37 drives the second lead screw 38 to rotate and drives the slider 41 to slide away from the partition 31. A tension spring 43 is fixedly installed on the side of the slider 41 away from the contact needle 42. The end of the tension spring 43 away from the slider 41 is fixedly connected to the inner wall of the testing machine 2. At the same time, the tension spring 43 pulls the slider 41 to accelerate the sliding speed of the slider 41.

[0037] In practical use, the user first inserts the HDMI interface into the connecting block on one side of the test machine 2. During insertion, the HDMI interface pushes the protrusion 33 into the connection port, causing the first gear block 32 to slide inwards. The first gear block 32 drives the first gear 341 and two first lead screws 342 to rotate, moving the two partitions 31 away from each other. Simultaneously, the partitions 31 drive the second gear 37 to rotate, which in turn drives the second lead screw 38 to rotate. The second lead screw 38 then drives the slider 41 to slide closer to the separating component 3, gradually bringing it into contact with the HDMI interface. When the HDMI interface is connected, this device... The device automatically pushes out the contact pin 42 and makes contact with the HDMI interface, preventing the contact pin 42 from becoming less elastic due to prolonged use and thus causing poor contact between the contact pin 42 and the HDMI interface. After the test is completed, the user unplugs the HDMI interface, and the compression spring 35 pushes out the first gear block 32, which drives the first gear 341 and the first lead screw 342 to rotate in opposite directions. The first lead screw 342 drives the two partitions 31 to slide towards each other, and drives the second gear 37 and the second lead screw 38 to rotate in opposite directions. The second lead screw 38 drives the slider 41 to slide away from the separating component 3. After the two partitions 31 move to fit together, they protect the contact pin 42 and prevent excessive dust accumulation near the contact pin 42 due to prolonged use, thus improving the testing accuracy of the device.
