Technical Field

[0001] This utility model belongs to the field of screen testing technology, and in particular relates to a test fixture for male and female connectors of display modules. Background Technology

[0002] Display modules are typically connected to the motherboard or other devices via male-female connectors, which are used to transmit power, data, and signals.

[0003] Currently, the testing method for display modules involves inserting the male and female snap fasteners of the module into the test snap fasteners for a pressing test. During the insertion process, the snap fasteners are very prone to popping up, causing deformation or damage during pressing, abnormal pressing, or poor contact during testing. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a test fixture for male and female buckle connectors of display modules, so as to solve the problem that the male and female buckles of the display module are very easy to lift up when inserted into the test buckle, causing deformation and damage or abnormal crimping during pressing, and poor contact during testing.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] like Figures 1 to 6As shown, this embodiment provides a test fixture for male and female snap-fit ​​connectors of display modules, comprising a test platform 1, a test base 2, a male and female snap-fit ​​cavity 21, a limiting plate 14, and a pressing cover plate 3. The test base 2 is fixedly mounted on the test platform 1. The male and female snap-fit ​​cavity 21 is mounted on the test base 2 and is used to place the male and female snap-fit ​​connectors of the display module under test. The limiting plate 14 is rotatably connected to the test base 2 and is used to flatten the male and female snap-fit ​​connectors of the display module under test within the male and female snap-fit ​​cavity 21. The pressing cover plate 3 is rotatably connected to the test base 2 and is used to press and flatten the male and female snap-fit ​​connectors of the display module under test and connect them to the test element extending into the male and female snap-fit ​​cavity 21 in the test platform 1 for connection testing.

[0031] Specifically, a rotating shaft 13 and a support 11 are provided on the side of the test base 2 away from the male and female snap-fit ​​cavity 21. The rotating shaft 13 is connected in the support 11. One side of the pressing cover plate 3 is rotatably connected to the rotating shaft 13. A first spring 12 is fixedly installed on the rotating shaft 13. The two ends of the first spring 12 are respectively fixed to the rotating shaft 13 and the pressing cover plate 3. The pressing of the male and female snap-fit ​​connectors of the display module under test can be automatically completed by pressing the pressing cover plate 3 with the first spring 12.

[0032] The limiting plate 14 is rotatably connected to the test base 2 via the limiting plate fixing block 15. The limiting plate fixing block 15 is fixedly installed in the groove opened in the test base 2. The limiting plate 14 is L-shaped, and the middle part of the limiting plate 14 is rotatably connected to the limiting plate fixing block 15. One end of the limiting plate 14 extends into the limiting rod 16. The limiting rod 16 can rotate into the male and female buckle cavity 21 with the rotation of the limiting plate 14 to press the male and female buckle connector of the display module under test to flatten the male and female buckle connector of the display module under test, so as to avoid the buckle under test from lifting up, which would cause deformation, damage or abnormal pressing during pressing.

[0033] A locking block 10 and a locking buckle 9 are fixedly installed in the recess on the side of the test base 2 near the male and female buckle cavity 21. A rotating rod is provided in the locking block 10, and the locking buckle 9 is rotatably connected to the rotating rod to fasten and lock the pressed cover plate 3 after pressing, and lock the pressed cover plate 3 to the test base 2 for testing.

[0034] A mounting groove 18 is provided in the crimping cover plate 3, and a crimping boss 19 is fitted into the mounting groove 18. The crimping boss 19 protrudes from below the crimping cover plate 3, and the horizontal cross-sectional area of ​​the upper part of the crimping boss 19 is larger than the horizontal cross-sectional area of ​​its lower part. The shape of the mounting groove 18 matches that of the crimping boss 19. An upper cover plate 17 is fixedly connected to the crimping cover plate 3 above the crimping boss 19. A spring mounting groove 20 is provided on the crimping boss 19, and a second spring is installed in the spring mounting groove 20. The second spring abuts against the upper cover plate 17, so that the crimping boss 19 has a crimping buffer function.

[0035] In addition, the test bench 1 is also equipped with a signal indication observation window 5, a start button 6, a screen loop button 7, and an anti-accidental touch protection button 8. The signal indication observation window 5, the start button 6, the screen loop button 7, and the anti-accidental touch protection button 8 are all control / display devices of the test circuit in the test bench 1, which are existing technologies and therefore will not be described in detail.

[0036] Working principle:

[0037] Place the male and female connectors of the display module under test into the male and female connector cavity 21. Rotate the limiting plate 14, and the limiting rod 16 will rotate into the male and female connector cavity 21 to press the male and female connectors of the display module under test to flatten them. Then, the pressing cover 3 will rotate again to press the flattened male and female connectors of the display module under test to connect with the test element in the test bench 1 that extends into the male and female connector cavity. The anti-accidental touch cover 4 is pressed to close the anti-accidental touch protection button 8 under gravity, connecting the test circuit. After pressing the start button 6, the display module under test is powered on and lit. The screen is switched and cycled by the screen cycle button 7. At the same time, the indicator light on and off can be observed through the signal indicator observation window 5 to determine whether the power supply is normal.

[0038] In summary, the test fixture for the male and female snap connectors of the display module first rotates the limiting plate 14 to flatten the male and female snap connectors of the display module under test in the male and female snap cavity 21, so as to avoid the snaps under test from lifting up, which would cause deformation, damage or abnormal pressing during the pressing process. Then the pressing cover plate 3 rotates again to flatten the male and female snap connectors of the display module under test and connect them to the test element in the test bench 1 that extends into the male and female snap cavity for testing. No poor contact will occur during the test.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
