[0026] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.

[0027] Please refer to Figure 1 - Figure 2 As shown, the present utility model designs a test fixture, which includes a base 1, a first elastic member 6 and a pressing component. The base 1 is provided with a first hook 8, a limiting groove 17 for limiting a test board 4, and a supporting seat 7 for supporting a socket. The supporting seat 7 is the same size as the socket and is provided with a plurality of through holes. The through holes, the test points on the socket and the probes on the test board 4 correspond one by one. The first elastic member 6 is arranged between the supporting seat 7 and the limiting groove 17. The pressing component is rotatably connected to the base 1 and is provided with a second hook 12 and a pressing block 10. When the pressing component rotates to the second hook 12 engaging with the first hook 8, the pressing block 10 presses the socket against the test board 4.

[0028] It should be noted that the size of the limiting groove 17 of the present utility model is the same as that of the test board 4, the size of the supporting seat 7 is the same as that of the socket, the test board 4 and the socket will not shift, and the through holes of the supporting seat 7, the test points on the socket and the probes on the test board 4 correspond one by one, ensuring that each test point can be accurately docked with the corresponding probe, improving the accuracy and reliability of the test. When the socket is pressed by the pressing component to abut against the test board 4, the first elastic member 6 can absorb impact and vibration, protecting the socket and the test board 4 from damage. The second hook 12 will engage with the first hook 8, ensuring that the pressing component is locked in the current position, making the socket closely abut against the test board 4, and solving the problem in the prior art that the installation of the socket and the test board 4 is not firm, resulting in a low accuracy rate of the test results.

[0029] Specifically, the pressing component further includes a rotating block 9 and a second elastic member 11. The rotating block 9 is rotatably connected to the base 1 and is provided with a groove. The second hook 12 is rotatably connected to the groove. The second elastic member 11 connects the groove and the second hook 12. When the rotating block 9 of the present utility model is pressed down, the first end of the second hook 12 will first abut against the first hook 8. Continuing to press down, the first hook 8 will push the first end of the second hook 12 to rotate in a direction away from the second hook 12. At this time, the second end of the second hook 12 will compress the second elastic member 11. Pressing down again until the first hook 8 and the second hook 12 cancel abutting, the elastic force of the second elastic member 11 will push the first end of the second hook 12 to rotate in a direction close to the first hook 8, and the second hook 12 can engage with the first hook 8.

[0030] Specifically, the pressing component further includes a sliding rod 13. The sliding rod 13 and the second elastic member 11 are respectively disposed on both sides of the second hook 12. The sliding rod 13 is slidably connected to the rotating block 9. The first end of the sliding rod 13 is limited within the groove and is used to push the second hook 12 to rotate.

[0031] Specifically, the pressing component further includes a limiting rod 14 rotatably connected to the rotating block 9. When the limiting rod 14 rotates to the first state, the limiting rod 14 is located between the rotating block 9 and the second end of the sliding rod 13 and is used to limit the sliding rod 13.

[0032] Specifically, the test fixture further includes a rotating shaft 2 and a torsion spring 3. The rotating shaft 2 penetrates through the rotating block 9 and the base 1. The torsion spring 3 is disposed on the rotating shaft 2, and both ends of the torsion spring 3 are respectively connected to the base 1 and the rotating block 9.

[0033] It should be noted that when the pressing component rotates in the direction close to the socket, the torsion spring 3 will store elastic potential energy. When the first hook 8 is engaged with the second hook 12, a gap will be formed between the second end of the sliding rod 13 and the rotating block 9. The size of this gap is the same as the size of the limiting rod 14. The limiting rod is located in this gap, and the sliding rod 13 cannot move in the direction close to the second hook 12, avoiding the sliding rod 13 being pressed to cause the second hook 12 to disengage from the first hook 8. Of course, when it is necessary to place or remove the socket, only need to make the limiting rod 14 disengage from the gap, and then press the sliding rod 13. The sliding rod 13 can move in the direction close to the second hook 12. The second elastic member 11 is in a compressed state, and the first end of the second hook 12 rotates in the direction away from the first hook 8 and disengages from the first hook 8. The torsion spring 3 will release the stored elastic potential energy and push the rotating block 9 to automatically reset to the original position.

[0034] Specifically, the pressing component further includes a third elastic member. Both ends of the third elastic member are respectively connected to the rotating block 9 and the pressing block 10. When the pressing block 10 presses the socket, the third elastic member can absorb part of the impact force and protect the socket and the test board 4 from being damaged.

[0035] Specifically, the test fixture further includes a guiding post 5. The guiding post 5 is connected to the limiting groove 17 and penetrates through the supporting seat 7. During the test, the guiding post 5 can ensure that the supporting seat 7 moves in the vertical direction when subjected to pressure, preventing it from shifting or tilting.

[0036] Specifically, the test fixture further includes an air pump. The base 1 is provided with an air inlet passage 15. The limiting groove 17 is communicated with the air inlet passage 15. The air pump is connected to the air inlet passage 15.

[0037] Specifically, on the side of the base 1 away from the air pump, there are also a plurality of heat dissipation holes 16. The plurality of heat dissipation holes 16 are all communicated with the limiting groove 17 and the outside.

[0038] After the test is completed, the air pump injects gas into the limiting groove 17 through the air inlet channel 15 and discharges it to the external environment through the heat dissipation holes 16. This gas flow helps to displace the hot air in the limiting groove 17 to ensure timely heat dissipation of the test board 4 and the socket.

[0039] Specifically, the test fixture further includes a heating box and a gripping manipulator. The heating box is used to heat the socket that has been limited in the test fixture, and the gripping manipulator is used to take out the socket that has been heated in the heating box. After the heating box of the present utility model heats the socket limited in the test fixture, the gripping manipulator takes it out, avoiding the problem of staff being scalded.

[0040] So far, the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
