[0023] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0024] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a side-insert mechanism applicable to a drawer jig of the present utility model includes a thrust installation base 1 and a bearing fixing block 2 provided above the thrust installation base 1. Two guide tightening members are provided on one side of the bearing fixing block 2, and a side-insert installation base 3 is provided on the side of the two guide tightening members far from the bearing fixing block 2. The top end of the thrust installation base 1 is connected with a thrust sliding seat 4 through a first guiding member. Oblique guiding members are provided at both ends of the bearing fixing block 2. A first resetting member for resetting the thrust sliding seat 4 is provided at the top end of the thrust installation base 1. A guide push block 5 is provided at the top end of the thrust sliding seat 4. Receiving grooves are provided on both sides of the guide push block 5. Guide push block hooks 6 are connected to the inside of the receiving grooves through rotating shafts. A first return spring 7 connected to the guide push block hooks 6 is provided on the inner wall of the receiving groove; the top end of the side-insert installation base 3 is connected with a rotating card installation base 8 through a second guiding member. A second resetting member for resetting the rotating card installation base 8 is provided at the top end of the side-insert installation base 3. An intermediate transfer push block 9 is connected to one end of the rotating card installation base 8 through a bolt. A clamping rod 10 matching the guide push block hooks 6 is provided at the end of the intermediate transfer push block 9. A rotating card installation cover plate 11 is provided at the top end of the rotating card installation base 8. A transfer card is fixedly connected between the rotating card installation base 8 and the rotating card installation cover plate 11 through a bolt.

[0025] Among them, the two guiding and pressing parts are respectively arranged on both sides of the transfer push block 9. The guiding and pressing part includes a guiding bearing fixing block 12. One end of the guiding bearing fixing block 12 facing the transfer push block 9 is provided with a first deep groove ball bearing 13. The guiding bearing fixing block 12 is fixed on the test fixture. After the guiding push block hook 6 abuts against the first deep groove ball bearing 13, the guiding push block hook 6 will latch onto the latching rod 10 of the transfer push block 9, playing a role of limiting, pressing and latching.

[0026] Among them, the first guiding part includes two first sliders 14 arranged at the bottom end of the thrust sliding seat 4. The top end of the thrust mounting base 1 is provided with a first sliding rail 15 that matches the first sliders 14. When the thrust sliding seat 4 moves, the first sliders 14 move under the action of the first sliding rail 15, improving the movement stability of the thrust sliding seat 4 and the movement precision of the thrust sliding seat 4.

[0027] Among them, the thrust sliding seat 4 includes a moving base 16. The top end of the moving base 16 is provided with a U-shaped guiding fixing block 17 and two side plate guiding blocks 18 connected to both sides of the guiding fixing block 17. The oblique guiding part includes fixing plates 19 arranged at both ends of the bearing fixing block 2. The inner wall of the fixing plate 19 is provided with second deep groove ball bearings 20. The outer wall of the side plate guiding block 18 is provided with guiding sliding grooves 21 that slide in match with the second deep groove ball bearings 20. When the thrust mounting base 1 rises, since the bearing fixing block 2 does not move, the second deep groove ball bearings 20 move inside the guiding sliding grooves 21, improving both the movement stability and the movement smoothness of the fixing plate 19. Under the guiding action of the first sliders 14 and the first sliding rail 15, the up-and-down force is converted into a front-and-back force, causing the thrust sliding seat 4 to move forward.

[0028] Among them, the first reset part includes two first guide rod fixing blocks 22 fixed to the top end of the thrust mounting base 1 by bolts. A first guide rod 23 is arranged between the two first guide rod fixing blocks 22. A first reset push block 24 connected to the moving base 16 is sleeved on the two first guide rods 23. A second reset spring 25 is sleeved on the first guide rod 23 and located between the first reset push block 24 and the first guide rod fixing block 22. During reset, under the action of the elastic potential energy of the second reset spring 25, the first reset push block 24 moves along the direction of the first guide rod 23, and the first reset push block 24 drives the moving base 16 to move horizontally, which can achieve a good reset.

[0029] Among them, the second guiding member includes two second guide rails 26 provided at the top end of the side-insert mounting base 3. The bottom end of the rotary card mounting base 8 is provided with second sliders 27 that slide in matching with the second guide rails 26. The second reset member includes two second guide rod fixing blocks 28 provided at the top end of the side-insert mounting base 3. A second guide rod 29 is provided between the two second guide rod fixing blocks 28. A second reset push block 30 connected to the rotary card mounting base 8 is sleeved on the two second guide rods 29. A third reset spring 31 is sleeved on the second guide rod 29 between the second reset push block 30 and the second guide rod fixing block 28. Under the action of the elastic potential energy of the third reset spring 31, the second reset push block 30 moves along the direction of the second guide rod 29. At the same time, the second slider 27 moves under the action of the second guide rail 26, improving the stability of the horizontal movement of the adapter card, and thus improving the accuracy of inserting the adapter card into the butt connector.

[0030] During operation, for the side-insert mechanism applicable to the drawer fixture, when the thrust mounting base 1 rises, the fixed plate 2 remains stationary. Under the guiding cooperation of the oblique guiding member and the first guiding member, the thrust sliding seat 4 moves towards one end of the middle transfer block 9, converting the up-and-down force into a front-and-back force. The thrust sliding seat 4 pushes the guiding push block 5 to move horizontally. The guiding push block 5 pushes the hook of the guiding push block 5 to move horizontally. When the hook of the guiding push block 5 touches the guiding tightening member, it will catch the engaging rod 10 of the middle transfer block 9 until the adapter card is pushed into the butt connector. Under the guiding action of the second guiding member, the adapter card achieves precise butt connection. When the thrust mounting base 1 retracts, under the guiding action of the first guiding member, the thrust sliding seat 4 moves backward, causing the entire butt movement to return to the original position. The first reset member will reset the entire transmission mechanism to the original position. The two first reset springs 7 will spring open the hook of the guiding push block 5 through the rotating shaft, causing it to disengage from the engaging rod 10 of the middle transfer block 9. The second reset member resets the plugging and unplugging mechanism to the original position, achieving long-distance butt connection with a short transmission. When the two test interfaces of the product are far apart in the drawer-type fixture, more convenient and accurate butt connection can be achieved; and the adapter card is installed between the rotary card mounting base 8 and the rotary card mounting cover plate 11 through bolts, making it convenient to replace the adapter card.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
