The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as a limitation on the utility model.

[0040] As Figures 1 to 6As shown, the embodiment provides a retreat prevention mechanism, which comprises a guide member 100, a bearing member 200 and a locking assembly 300. The guide member 100 has a guide groove 110 extending in a first direction; the bearing member 200 is arranged in the guide groove 110 and can reciprocate relative to the guide member 100 in the first direction to extend out of the guide groove 110 or enter the guide groove 110; the locking assembly 300 has a locking member 310 which can reciprocate relative to the guide member 100 in a second direction to move onto or out of the moving path of the bearing member 200, the locking member 310 has a locking surface 311 and a guide surface 312, when the locking member 310 moves onto the moving path of the bearing member 200, the locking surface 311 abuts against the bearing member 200 to limit the bearing member 200 from extending out of the guide groove 110; the guide surface 312 is arranged to cooperate with the end surface of the bearing member 200 when the bearing member 200 enters the guide groove 110 to move the locking member 310 out of the moving path of the bearing member 200; the second direction is arranged at an angle with the first direction.

[0041] With the above arrangement, when the locking member 310 in the locking assembly 300 is located on the moving path of the bearing member 200, the locking surface 311 of the locking member 310 can abut against the bearing member 200 to prevent the bearing member 200 from being pulled out of the guide groove 110 of the guide member 100; when it is needed to pull the bearing member 200 out of the guide groove 110 of the guide member 100, the locking member 310 needs to be moved out of the moving path of the bearing member 200, which avoids the situation of accidental pulling out and reduces the possibility of damage to the electrical element; in addition, since the guide member 100 has the guide surface 312, when the bearing member 200 moves into the guide groove 110, the guide surface 312 can be abutted to move the locking member 310 out of the moving path of the bearing member 200, so that the bearing member 200 can smoothly enter the guide groove 110, improving the moving efficiency of the bearing member 200 into the guide groove 110 and the convenience of operation.

[0042] To improve the convenience of pushing the bearing member 200 into the guide groove 110, in some embodiments, the end of the bearing member 200 has a pressure receiving portion 211 arranged corresponding to the guide member 100; the retreat prevention mechanism further comprises a power assisting member 400, which has a power assisting body 410 and a holding portion 420 arranged on the power assisting body 410 and used for being held by an operator, the side of the power assisting body 410 away from the holding portion 420 has a pushing portion for abutting against the pressure receiving portion 211, the pushing portion abuts against the pressure receiving portion 211 to push the bearing member 200 into the guide groove 110. With the arrangement of the power assisting member 400, the operator can hold the holding portion 420 to exert force, thereby reducing the difficulty of pushing the bearing member 200 into the guide groove 110.

[0043] In this embodiment, the carrier 200 can be an aging test board used to carry the chip under test (semiconductor IC) and is electrically and / or communicatively connected to the chip under test. In use, after the carrier 200 moves into the guide groove 110, it needs to be plugged in to achieve electrical and / or communication connections between the carrier 200 and the test module, thereby realizing the electrical and / or communication connections between the chip under test and the test module. Before the carrier 200 moves out of the guide groove 110, it needs to be pulled out to disconnect the carrier 200 from the test module. This plugging and pulling process requires considerable force. Therefore, the anti-retraction mechanism also includes a support 500, which has a prying part. The assisting part 400 also includes an assisting part 440 located on the side of the assisting body 410 away from the gripping part 420. The assisting part 440 can abut against the prying part to pry the carrier 200 into the guide groove 110 and plug it into the test module. The prying method makes it easier for the carrier 200 to plug into the test module. In this case, the distance between the position where the assist part 440 and the prying part meet and the pushing part is less than the distance between the pushing part and the gripping part 420, thus making the prying process more effortless.

[0044] Regarding the structure of the lever, combined with Figure 3 and Figure 4 As shown, in some embodiments, the support member 500 has a support channel 510 extending along a third direction. A first support wall 512 of the support channel 510, away from the guide member 100, forms a prying portion. An assisting portion 440 is a rod-shaped structure protruding from one side of the assisting body 410. The assisting portion 440 can be inserted into the support channel 510 and can abut against the first support wall 512. The third direction is perpendicular to both the first and second directions. The second direction is perpendicular to the first direction, as shown in the reference section. Figure 1 The first direction is the front-to-back direction, the second direction is the up-and-down direction, and the third direction is the left-to-right direction. The support channel 510 is easy to process and can reduce the weight of the support component 500, thus reducing costs. In addition, the bottom surface of the support channel 510 forms a support part 511. When the assist part 440 is inserted into the support channel 510, the support part 511 supports the assist part 440, which also helps to reduce the labor intensity of the operator.

[0045] The pushing part is a first pin 450 provided on the assist body 410, and the first pin 450 at least partially protrudes from one side of the assist body 410; the bearing member 200 is provided with a groove 210, which is used for... Figure 6As shown, the first pin 450 can be inserted into the groove 210, and one side wall of the groove 210 forms a pressure bearing part 211. The arrangement of the first pin 450 and the groove 210 can provide guidance for the placement position of the assisting part 400, improving operability; at the same time, when the first pin 450 pushes against one side wall of the groove 210, it will contact the groove bottom of the groove 210, avoiding relative sliding between the first pin 450 and the groove 210, ensuring the stability of the relative position between them, so that the pushing process of the bearing part 200 is more stable.

[0046] The bearing part 200 has two pressure bearing parts 211 arranged along the third direction, and the retreat prevention mechanism has two guide parts 100 and two supporting parts 500. The two guide grooves 110 in the two guide parts 100 are arranged along the third direction and the openings are oppositely arranged; the two supporting channels 510 in the two supporting parts 500 are arranged corresponding to the two guide grooves 110 and the two pressure bearing parts 211. The two assisting parts 400 can be arbitrarily matched with the two supporting parts 500. The assisting part 400 further includes a second pin 460 provided on the assisting body 410, which at least partially protrudes from the other side of the assisting body 410; the second pin 460 can be inserted into the groove 210 and push against the other side wall of the groove 210 to move the bearing part 200 out of the guide groove 110. The arrangement of the two pressure bearing parts 211 makes the pushing process of the bearing part 200 more stable, helps the bearing part 200 to enter the guide groove 110 smoothly, reduces the pushing force required by a single assisting part 400, and reduces the difficulty of pushing; in addition, the two assisting parts 400 can realize the pushing and dragging actions on the bearing part 200 after the positions are exchanged left and right. Specifically, before the left and right positions of the two assisting parts 400 are exchanged, the first pin 450 is located below the second pin 460, the first pins 450 of the two assisting parts 400 are matched with the two corresponding grooves 210 respectively, the two assisting parts 400 are pushed to push the bearing part 200 into the guide groove 110; after the left and right positions of the two assisting parts 400 are exchanged, the first pin 450 is located above the second pin 460, the second pins 460 of the two assisting parts 400 are matched with the two corresponding grooves 210 respectively, the two assisting parts 400 are dragged outward to drive the bearing part 200 to move outward to separate from the test module.

[0047] Further, the support channel 510 forms a second support wall 513 close to the side wall of the guide 100, and the power assisting part 440 abuts against the second support wall 513 to pry the carrier 200 to move out of the guide slot 110. In the first direction, the width of the support channel 510 is greater than the thickness of the power assisting part 440, so that the power assisting part 440 can be twisted in the support channel 510. The carrier 200 is provided with a handle 220. The prying manner makes the carrier 200 more easily separated from the to-be-tested module, and after the two are separated, the carrier 200 is pulled out of the guide slot 110 by the handle 220. The distance between the position where the power assisting part 440 abuts against the second support wall 513 and the second pin 460 is less than the distance between the second pin 460 and the holding part 420, so that the prying process is more labor-saving.

[0048] To improve the continuity of operation, in some embodiments, the power assisting part 400 further comprises an unlocking block 430 provided on the power assisting body 410 and protruding from the other side of the power assisting body 410; in the first direction, the second pin 460 is arranged in a spaced manner with the unlocking block 430, and when the second pin 460 is inserted into the groove 210, the unlocking block 430 presses the locking part 310 to move out of the movement path of the carrier 200, and at this time, a gap is provided between the unlocking block 430 and the carrier 200, so that when the carrier 200 is pulled out, the unlocking block 430 presses the locking part 310 changes to the carrier 200 pressing the locking part 310. In use, the two locking parts 310 are pressed by the two unlocking blocks 430 respectively, so that the two locking parts 310 move out of the movement path of the carrier 200, and then the carrier 200 is moved in the direction of moving out of the guide slot 110 by prying, so that the carrier 200 moves outward and separates from the test module.

[0049] To facilitate processing and assembly, in some embodiments, the first pin 450 and the second pin 460 are integrally formed to form a columnar long pin. The power assisting body 410 is provided with a pin hole, and the long pin is partially located in the pin hole and protrudes from both ends of the pin hole to form the first pin 450 and the second pin 460, respectively.
