[0056] The utility model provides a push-button type test fixture, which is used for clamping and fixing a to-be-tested device of a smart watch in an application scenario for electrical testing of the to-be-tested device. It can clamp and position the to-be-tested device in both horizontal and vertical directions, thereby solving the problem that the to-be-tested device is likely to affect the test result due to displacement.

[0057] See Figures 1 to 5 , in this embodiment, the push-button type test fixture includes a fixture base 1, a horizontal clamping plate 2, a clamping plate spring 3, a button assembly 4, a rotating cover plate 5, a cover plate lock block 6, and a lock block spring 7.

[0058] A receiving groove 1011 is provided on the top surface of the fixture base 1; the horizontal clamping plate 2 is located in the receiving groove 1011 and is slidably connected to the fixture base 1 in the horizontal direction. The clamping plate spring 3 abuts against the horizontal clamping plate 2 and is used to drive the horizontal clamping plate 2 to cooperate with the fixture base 1 to horizontally clamp the to-be-tested device.

[0059] The button assembly 4 is installed in the fixture base 1 and is located on the side of the horizontal clamping plate 2 away from the clamping plate spring 3; wherein, the button assembly 4 has an un-pressed state of abutting against the horizontal clamping plate 2 to limit the horizontal clamping plate 2 from clamping the to-be-tested device; and has a pressed state of releasing the limit on the horizontal clamping plate 2 after being pressed.

[0060] The rotating cover plate 5 is hinged to the fixture base 1 around a horizontal axis and is used to cooperate with the fixture base 1 to vertically clamp the to-be-tested device. The cover plate lock block 6 is slidably connected to the fixture base 1, and a lock hook portion 601 is provided at one end of the cover plate lock block 6 close to the rotating cover plate 5. The lock block spring 7 is located on the side of the cover plate lock block 6 away from the rotating cover plate 5 and is used to drive the lock hook portion 601 to slide above the rotating cover plate 5 to limit the rotation and opening of the rotating cover plate 5. Correspondingly, a locking groove 501 for inserting the lock hook portion 601 is provided at the position of the rotating cover plate 5 corresponding to the lock hook portion 601.

[0061] For the push-button type test fixture provided in this embodiment, at the beginning, the button assembly 4 is in an un-pressed state. After the to-be-tested device is placed in the fixture base 1, the button assembly 4 is pressed to release the limiting effect of the button assembly 4 on the horizontal clamping plate 2. The horizontal clamping plate 2 is driven by the clamping plate spring 3 to cooperate with the fixture base 1 to clamp the to-be-tested device, and thus the horizontal clamping and positioning can be completed;

[0062] Then, the rotating cover plate 5 is rotated and closed, and the lock block spring 7 drives the lock hook portion 601 to insert into the locking groove 501 to prevent the rotating cover plate 5 from being opened, and thus the vertical clamping and positioning of the to-be-tested device can be realized.

[0063] Therefore, the button-type test fixture provided by the present utility model can perform vertical and horizontal clamping and positioning on devices to be tested such as smart watches, thereby solving the problem that the devices to be tested are likely to affect the test results due to displacement.

[0064] In this embodiment, the fixture base 1 includes a base body 101 provided with the accommodation groove 1011 and a fixed clamping plate 102 installed in the accommodation groove 1011. Among them, a fixed U-shaped groove 1021 is provided at the end position of one end of the fixed clamping plate 102, and a fixed clamping portion 1022 is provided at the side position of the fixed U-shaped groove 1021.

[0065] On the side of the fixed clamping portion 1022 away from the fixed U-shaped groove 1021, there is a clamping plate avoidance groove 1023. The horizontal clamping plate 2 includes a clamping plate body 201 located directly below the fixed clamping plate 102 and a horizontal push block 202 fixedly provided at the top of the clamping plate body 201 and protruding upward through the clamping plate avoidance groove 1023. Among them, the clamping plate spring 3 abuts against the surface of the horizontal push block 202 close to the fixed U-shaped groove 1021.

[0066] The clamping plate body 201 is located directly below the fixed clamping plate 102. A plug-in space 2011 for inserting the device to be tested is provided at the position of the clamping plate body 201 directly below the fixed U-shaped groove 1021, and a movable clamping portion 2012 for cooperating with the fixed clamping portion 1022 to clamp the device to be tested is provided at the side position of the plug-in space 2011.

[0067] A test main board 8 is provided directly below the horizontal clamping plate 2, and a test probe 801 for electrically connecting with the device to be tested is provided at the position of the test main board 8 corresponding to the plug-in space 2011.

[0068] A button avoidance groove 1024 is provided on the side of the clamping plate avoidance groove 1023 away from the fixed U-shaped groove 1021. The button assembly 4 includes a button body 401 protruding upward through the button avoidance groove 1024 and a button spring 402 located below the button body 401 to drive the button body 401 to move upward relative to the fixed clamping plate 102.

[0069] The button body 401 includes a pressing block 4011 extending into the button avoidance groove 1024 and a limiting plate 4012 located between the pressing block 4011 and the button spring 402. The distance from the limiting plate 4012 to the horizontal clamping plate 2 is smaller than the distance from the pressing block 4011 to the horizontal clamping plate 2.

[0070] For the button-type test fixture provided in this embodiment, at the beginning, refer to Figure 2 and Figure 3, the limiting plate 4012 is at the same height as the transverse clamping plate 2. Under the abutting action of the limiting plate 4012, the transverse clamping plate 2 cannot slide to the left. Therefore, the distance between the fixed clamping portion 1022 and the movable clamping portion 2012 is relatively large to facilitate the insertion of the device under test;

[0071] After placing the device under test between the fixed clamping portion 1022 and the movable clamping portion 2012, refer to Figure 4 and Figure 5 , press the pressing block 4011, and the limiting plate 4012 moves to a position lower than the transverse clamping plate 2. Under the elastic force of the clamping plate spring 3, the transverse clamping plate 2 moves to the left. Therefore, the fixed clamping portion 1022 and the movable clamping portion 2012 cooperate to clamp the device under test horizontally;

[0072] After the test is completed, when the device under test needs to be taken out, after pushing the transverse push block 202 to the right, the button spring 402 pushes the button body 401 upward. Therefore, the limiting plate 4012 moves upward again to the same height as the transverse clamping plate 2, thereby realizing reset for the next clamping operation.

[0073] Optionally, an inclined surface 4012a is provided at the end face of the limiting plate 4012 close to the transverse clamping plate 2 to facilitate the transverse clamping plate 2 to move above the limiting plate 4012.

[0074] In summary, the key-type test fixture provided in this embodiment has the following beneficial effects: After placing the device under test on the fixture base 1, pressing the button assembly 4 can complete the horizontal clamping and positioning, and rotating and closing the rotating cover plate 5 can realize the longitudinal clamping and positioning of the device under test; Therefore, it can perform horizontal and vertical clamping and positioning on devices under test such as smart watches, thus solving the problem that the device under test is likely to affect the test results due to displacement.

[0075] Finally, it should be noted that although the above embodiments have been described in the text of the specification and drawings of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions generated by equivalent structure or equivalent process substitution or modification using the content recorded in the text of the specification and drawings of this application based on the essential concept of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of this application.
