[0001] This utility model relates to the field of adapter board technology, and in particular to an adapter board that facilitates testing of LCD displays. Background Technology

[0002] During the production and testing of existing LCD displays, test fixtures are required to conduct power-on tests on their interfaces to verify display effects and electrical performance. Because LCD displays come in various models and interface specifications, such as 40-pin, 50-pin, and 60-pin, with differences in the number and arrangement of pins, current technology typically requires a separate test adapter board for each interface specification.

[0003] However, this means that operators must frequently change different test adapter boards during batch testing, which not only increases the complexity of operation but also easily causes wear and tear on the interface, thus affecting signal stability and test accuracy. Therefore, an adapter board that is easy to test LCD displays is proposed. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0037] Example

[0038] Reference Figures 1 to 6 This embodiment provides an adapter board for easy testing of LCD displays, which can quickly adapt to LCD displays of different models and interfaces. It includes a rotating component, a testing component, a switching component, a limiting component, and a driving component.

[0039] Specifically, the rotating assembly includes a central cylinder 8 and a mounting base 1 rotatably disposed outside the central cylinder 8. A base 7 is provided at the bottom of the central cylinder 8, and the bottom surface of the base 7 is provided with anti-slip texture 11. A wire-passing groove 10 is opened at the bottom of the base 7 facing the central cylinder 8. The anti-slip texture 11 effectively increases friction, making it less likely for the entire device to slide when placed on the workbench, thereby ensuring stability during the testing process. The wire-passing groove 10 allows the power cable of the device to pass through from the bottom in a reasonable manner, improving the neatness of the wiring and operational safety.

[0040] The test assembly includes adapter plates 4 arrayed on a mounting base 1. The outer wall of the mounting base 1 has arrayed storage slots 2. The adapter plates 4 are installed in the inner bottom of the storage slots 2. The opening of the storage slots 2 is detachably covered with a dust cover 3. The arrayed storage slots 2 can install adapter plates 4 of different interface types. When testing a specific model of LCD display, the operator only needs to rotate the mounting base 1 to move the corresponding adapter plate 4 to the working position. The dust cover 3 prevents dust from contaminating the adapter plates 4, ensuring the signal contact surface is clean, thereby improving the accuracy of the test results.

[0041] The switching assembly includes an elastic conductive sheet 14 disposed on the central cylinder 8. The mounting base 1 has a central hole 6 through which the central cylinder 8 passes. The inner wall of the hole 6 is provided with a contact 9 electrically connected to the adapter plate 4. The elastic conductive sheet 14 and the contact 9 correspond to each other. When the elastic conductive sheet 14 separates from the contact 9, the circuit is disconnected, preventing short circuits or signal interference during rotation switching. When returning to the test state, the elastic conductive sheet 14 will re-abut the contact 9 to realize circuit conduction.

[0042] A square hole 13 is provided through the outer wall of the central cylinder 8. An elastic conductive sheet 14 is disposed at the bottom of the square hole 13. The inner side of the elastic conductive sheet 14 is an inclined surface and is located inside the central cylinder 8. The inclined surface of the elastic conductive sheet 14 allows the extrusion block 21 to apply a progressive thrust to the elastic conductive sheet 14 when it moves up and down, thereby avoiding metal fatigue or contact 9 wear caused by hard pressing.

[0043] The limiting components include a rotating disk 23 disposed at the bottom of the central cylinder 8 and a limiting block 16 disposed at the bottom of the rotating disk 23. The outer end of the limiting block 16 penetrates the central cylinder 8 and engages with the mounting base 1. A through hole 15 is provided on the lower outer wall of the central cylinder 8, and a positioning groove 12 is provided in a circular array on the lower inner wall of the sleeve hole 6. The limiting block 16 penetrates the through hole 15 and its outer end is located inside the positioning groove 12. The limiting block 16 can be stably locked in the positioning groove 12, so that the mounting base 1 remains fixed after the rotation switching is completed.

[0044] The bottom surface of the rotating disk 23 is provided with an arc groove 24, and the top of the inner end of the limiting block 16 is provided with a guide block 25. The guide block 25 is located inside the arc groove 24 and is slidably connected. Guided by the arc of the arc groove 24, the guide block 25 can drive the limiting block 16 to complete radial movement when the rotating disk 23 rotates.

[0045] The drive assembly includes a shaft 22 disposed on the top of the rotating disk 23, an extrusion block 21 disposed outside the shaft 22, a guide block 27 disposed inside the extrusion block 21, and a threaded groove 20 disposed on the outer surface of the shaft 22. The guide block 27 is located inside the threaded groove 20. The drive assembly realizes the conversion between linear motion and rotational motion through the cooperation between the threaded groove 20 and the guide block 27.

[0046] The center of the extrusion block 21 has a circular hole 26 for the shaft post 22 to pass through. The guide block 27 is disposed on the inner wall of the circular hole 26. The extrusion block 21 is located below the top of the elastic conductive sheet 14. When the extrusion block 21 moves down, it can release the extrusion and disconnect the circuit. When it moves up, it applies external force to the elastic conductive sheet 14 again, causing it to spring out and contact the contact point 9, and the circuit is turned on.

[0047] A connecting cylinder 18 is provided on the top of the extrusion block 21, and a pressure plate 5 is provided on the top of the connecting cylinder 18. The pressure plate 5 covers the port of the sleeve hole 6. A support frame 17 is provided on the inner wall of the upper port of the central cylinder 8. The threaded groove 20 penetrates the support frame 17 and slides vertically and vertically connected to each other. A spring 19 is provided between the bottom surface of the pressure plate 5 and the top surface of the support frame 17. The spring 19 stores elastic potential energy when compressed. When the pressure plate 5 is released, the energy is released, pushing the pressure plate 5 to reset and causing the extrusion block 21 and other components to move in the opposite direction.

[0048] When in use, open the dust cover 3 to expose the adapter plate 4. Use the adapter plate 4 to test the power supply of the LCD display. Different LCD displays have different test interfaces, so it is necessary to replace the adapter plate 4 with a compatible one for testing. Press the pressure plate 5 to compress the spring 19 and push the connecting cylinder 18 downward. The connecting cylinder 18 drives the pressing block 21 downward. The pressing block 21 no longer presses and pushes the elastic conductive sheet 14. The elastic conductive sheet 14 resets and no longer abuts the contact point 9. While the pressing block 21 moves downward, it drives the guide block 27 to move downward along the threaded groove 20. The shaft 22 is passively rotated through the threaded groove 20, which in turn drives the rotating disk 23 to rotate. The rotation of the shaft 22 pulls the guide block 25 through the arc groove 24. Since the movement trajectory of the limit block 16 is limited by the through hole 15, the guide block 25 drives the limit block 16 to move radially and disengage from the positioning groove 12. The mounting base 1 can rotate relative to the central cylinder 8, and then the adapter plate 4 in different positions can be replaced for testing.

[0049] Once the switching is complete, the pressure plate 5 is released. The pressure plate 5 moves upward under the reset push of the spring 19. The pressure plate 5 pulls the extrusion block 21 upward through the connecting cylinder 18. The extrusion block 21 drives the guide block 27 to move upward along the threaded groove 20. The shaft 22 is passively rotated in the opposite direction through the threaded groove 20, which in turn drives the rotating disk 23 to rotate in the opposite direction. The rotation of the shaft 22 pushes the guide block 25 through the arc groove 24. Since the movement trajectory of the limit block 16 is limited by the through hole 15, the guide block 25 drives the limit block 16 to move radially and insert into the positioning groove 12. The mounting base 1 is fixed relative to the center cylinder 8. The adapter plate 4 will not be displaced during the test. While the extrusion block 21 moves upward, it contacts the elastic conductive sheet 14. Since the inner surface of the elastic conductive sheet 14 is an inclined surface, the extrusion block 21 squeezes and pushes the elastic conductive sheet 14 outward. The elastic conductive sheet 14 abuts against the contact point 9 to complete the circuit conduction and avoid wear during rotation that could lead to poor contact.

[0050] In summary, this embodiment achieves rapid switching, stable limiting, and reliable conduction of the adapter board 4, solving the problems of low testing efficiency, poor contact, and poor interface compatibility in the prior art.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
