Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a quick-connect fixture for a test piece. Background Technology

[0002] In traditional part-time test (DUT) mating testing, fixture designs are often complex and operations are cumbersome, leading to low testing efficiency. Furthermore, the fixture's fixing method is not always secure enough, making it prone to DUT detachment or displacement during testing, severely impacting accuracy. Therefore, there is an urgent market need for a fixture that can quickly and accurately mate and fix the DUT to improve testing efficiency and ensure accuracy. This invention addresses this need by proposing a rapid DUT mating fixture. It aims to simplify the fixture structure and optimize the operation process to achieve rapid fixation and mating of the DUT, thereby improving testing efficiency and ensuring smooth testing. Utility Model Content

[0003] The purpose of this invention is to provide a quick mating fixture for the test piece, which solves the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution:

[0005] A quick-connect fixture for a test piece (DPT) is provided. A slide assembly is fixedly mounted on one end of the base surface, and a wire harness box is fixedly mounted on the other end. A movable plate is mounted on the slide assembly, and the slide assembly can drive the movable plate to move towards the wire harness box. Two stiffening plates are also vertically mounted on the front and rear sides of the movable plate, perpendicular to the wire harness box. A pull rod collar assembly is installed on the outer side of the two stiffening plates, and the two stiffening plates are fixedly connected to a fixed plate by pins in the direction close to the wire harness box. A pressure plate for fixing the DPT is inserted through the pins. Pull rod collar buckles that can cooperate with the pull rod collar assembly are fixed on both sides of the pressure plate. The wire harness box has a mounting hole at the position directly opposite the DPT for installing a front adapter plate.

[0006] Furthermore,

[0007] The wiring harness box has a rear adapter plate on the side opposite to the front adapter plate, and adapters are installed on both the front and rear adapter plates.

[0008] Furthermore,

[0009] The slide assembly includes a U-shaped slide, a handle, a limiting rod, a threaded rod, and a slider. The slide is installed on one end of the base surface and is opposite to the wire harness box. The slide is provided with a threaded rod and two limiting rods, with the threaded rod between the two limiting rods. The handle is located at the end away from the wire harness box and passes through the slide and is connected to the threaded rod. The slider is sleeved on the limiting rod and the threaded rod and is parallel to the slide.

[0010] Furthermore,

[0011] The movable plate is disposed on the upper surface of the slider and can move with the slider. Slots for inserting stiffeners are provided on both the front and rear sides of the movable plate.

[0012] Furthermore,

[0013] The pull rod collar assembly includes a handle base, a U-shaped handle, a pull rod collar, and a rotating shaft. The handle base is installed on the outside of the stiffener plate, the U-shaped handle is installed on the handle base, and a rotating shaft is provided between the U-shaped handles. The connecting rod end of the pull rod collar is fixed on the rotating shaft, and the collar end faces the wire harness box.

[0014] Furthermore,

[0015] The pressure plate is ring-shaped, with through holes at the corresponding pin positions. The pressure plate is fitted onto the pin through the through holes, and equally spaced toothed blocking blocks are provided on the inner sides of the upper and lower ends of the pressure plate in the direction close to the wire harness box. Pull rod collar buckles that can match the collar ends of the pull rod collar are provided on both sides of the pressure plate at the positions corresponding to the pull rod collar assembly.

[0016] Furthermore,

[0017] The fixing plate is also ring-shaped, and its opening is smaller than that of the pressure plate.

[0018] Furthermore,

[0019] The front adapter plate can match the interface on the test piece, and limiting holes are opened on both sides of the front adapter plate at the positions corresponding to the pins to accommodate the pins.

[0020] Furthermore,

[0021] The base has handles on both sides.

[0022] The beneficial effects of this utility model are:

[0023] 1. The component under test (DUT) is moved from the sliding plate and stiffeners to the wire harness box via a slide assembly. Combined with the design of the pressure plate and fixing plate, the DUT can be quickly and accurately mated and fixed. This design not only improves work efficiency but also ensures the accuracy of the test.

[0024] 2. The design of the pull rod collar assembly makes locking and unlocking between the pressure plate and the fixed plate quick and convenient. The operator only needs to drive the rotating shaft with the U-shaped handle to control the collar end of the pull rod collar to engage or disengage with the pull rod collar buckle on the pressure plate, thereby achieving quick fixing or release of the workpiece to be tested.

[0025] 3. The equally spaced toothed blocking blocks on the inner sides of the upper and lower ends of the pressure plate effectively prevent the test piece from falling off the pressure plate during testing, ensuring the smooth progress of the test. At the same time, the design of the annular opening of the fixing plate can both accommodate the test piece and prevent it from sliding out of the annular opening of the fixing plate, further enhancing the stability of the clamping.

[0040] Example

[0041] See Figures 1 to 8 :

[0042] A quick-connect clamp for a test piece (UTP) is provided. A slide assembly 2 is fixedly mounted on one end of the surface of the base 1, and a wire harness box 3 is fixedly mounted on the other end. A movable plate 4 is mounted on the slide assembly 2, and the slide assembly 2 can drive the movable plate 4 to move towards the wire harness box. Two stiffening plates 5 are also vertically mounted on the front and rear sides of the movable plate 4, perpendicular to the wire harness box 3. A pull rod collar assembly 6 is installed on the outer side of the two stiffening plates 5, and the two stiffening plates 5 are fixedly connected to a fixing plate 8 by a pin 7 in the direction close to the wire harness box 3. A pressure plate 9 for fixing the test piece 10 is inserted through the pin 7. Pull rod collar buckles 91 that can cooperate with the pull rod collar assembly 6 are fixed on both sides of the pressure plate 9. The wire harness box 3 has a mounting hole in the position directly opposite the test piece 10 for installing a front adapter plate 11.

[0043] The sliding table assembly 2 drives the moving plate 4 and the rib plate 5 on the moving plate 4 to move. The fixed plate 8 is fixed to the rib plate 5 by pins 7.

[0044] Furthermore,

[0045] The wiring harness box 3 has a rear adapter plate 12 on the side opposite to the front adapter plate 11, and adapters 14 are installed on both the front adapter plate 11 and the rear adapter plate 12.

[0046] Furthermore,

[0047] The slide assembly 2 includes a U-shaped slide 20, a rotating handle 21, a limiting rod 22, a threaded rod 23, and a slider 24. The slide is installed on one end of the surface of the base 1 and is opposite to the wire harness box 3. The slide is provided with a threaded rod 23 and two limiting rods 22, with the threaded rod 23 between the two limiting rods 22. The handle is located at one end away from the wire harness box 3 and passes through the slide and connects to the threaded rod 23. The slider 24 passes through the limiting rod 22 and the threaded rod 23 and is parallel to the slide. The threaded rod 23 has a thread in the hole through the slider 24 that is compatible with the threaded rod 23.

[0048] The U-shaped slide 20 allows for easy installation of a limiting rod 22 and a threaded rod 23. The connection between the handle and the threaded rod 23 allows the operator to rotate the handle, thereby rotating the threaded rod 23. At the same time, the limiting rod 22 limits the slider 24, allowing the slider 24 to slide on the slide, thereby driving the components on the slider 24 to move together.

[0049] In one embodiment, the slider 24 and the slide table are directly adopted as the slide table and slider 24 of XKST-50 or the limiting rod 22 and the threaded rod 23 are arranged side by side to restrict the slider 24 to move only in a straight line and prevent the moving plate 4 from deviating and shaking during the sliding process.

[0050] Furthermore,

[0051] The movable plate 4 is disposed on the upper surface of the slider 24 and can move together with the slider 24. Slots 40 for inserting the reinforcing plate 5 are provided on both the front and rear sides of the movable plate 4.

[0052] The slot 40 makes the stiffener 5 removable for easy maintenance. The movable plate 4 is fixedly connected to the slider 24, ensuring that the slide assembly 2 can effectively transmit the driving force to the stiffener 5 and push the test piece 10 to be precisely inserted.

[0053] Furthermore,

[0054] The pull rod collar assembly 6 includes a handle base 60, a U-shaped handle 61, a pull rod collar 62, and a rotating shaft 63. The handle base 60 is installed on the outside of the stiffener 5, the U-shaped handle 61 is installed on the handle base 60, and the rotating shaft 63 is provided between the U-shaped handles 61. The connecting rod end of the pull rod collar 62 is fixed on the rotating shaft 63, and the collar end faces the wire harness box 3.

[0055] The U-shaped handle 61 drives the rotating shaft 63, controlling the engagement or disengagement of the collar end of the pull rod collar 62 with the pull rod collar buckle 91 on the pressure plate 9, thereby achieving quick locking or unlocking between the pressure plate 9 and the fixed plate 8. Throughout the process, the U-shaped handle 61 provides a lever effect, reducing the force required for operation and improving the convenience of operation.

[0056] Furthermore,

[0057] The pressure plate 9 is annular, with through holes at the positions corresponding to the pins 7. The pressure plate 9 is fitted onto the pins 7 through the through holes. The inner sides of the upper and lower ends of the pressure plate 9 are provided with equally spaced toothed blocking blocks 90 in the direction close to the wire harness box 3. Pull rod collar 62 buckles that can match the collar ends of the pull rod collar 62 are provided on both sides of the pressure plate 9 at the positions corresponding to the pull rod collar assembly 6.

[0058] The toothed barrier block 90 can limit the test piece 10 and prevent it from falling off the pressure plate 9. The toothed barrier block 90 can be replaced by other shapes as long as it does not affect the test of the test piece 10.

[0059] Furthermore,

[0060] The fixing plate 8 is the same size as the pressure plate 9 and is also annular, but its annular opening is smaller than the annular opening formed by the pressure plate 9.

[0061] The annular opening of the fixing plate 8 is smaller than the annular opening of the pressure plate 9. The purpose is to allow the portion of the fixing plate 8 that is higher than the annular opening of the pressure plate 9 after the pressure plate 9 and the fixing plate 8 are locked, so that the part of the fixing plate 8 that is higher than the annular opening of the pressure plate 9 can act as a limiting plate to prevent the test piece 10 from sliding out from the annular opening of the fixing plate 8. Based on the above description of the pressure plate 9 and the fixing plate 8, a receiving cavity is formed between the plate and the fixing plate 8, which can just accommodate the test piece 10.

[0062] The annular opening of the mounting plate 8 needs to expose the back of the test piece 10, because the back of the test piece 10 may have an interface for connecting to other devices.

[0063] Furthermore,

[0064] The adapter 14 on the front adapter plate 11 can match the interface on the test piece 10, and limiting holes 110 are opened on both sides of the front adapter plate 11 at the positions corresponding to the pins 7 to accommodate the pins.

[0065] The limiting hole 110 cooperates with the pin 7 to ensure that the adapter 14 on the front adapter plate is fully aligned with the interface of the test piece 10, avoiding damage caused by misalignment during the insertion process. At the same time, it also limits the movement to prevent the operator from excessively rotating the rotating handle 21, which would cause the threaded rod 23 to drive the slider 24 to move excessively, resulting in the front adapter plate 11 and the interface of the test piece 10 being squeezed and damaged.

[0066] Furthermore,

[0067] The base 1 has handles 13 on both sides.

[0068] Handle 13 facilitates the handling and repositioning of the fixture, making it especially suitable for testing scenarios requiring frequent fixture movement.

[0069] The method of using this utility model is as follows:

[0070] First, the operator can place the test piece 10 inside the pressure plate 9 and then make it contact with the fixing plate 8. At this time, the toothed blocking blocks 90 on the inner side of the upper and lower ends of the pressure plate 9 will limit the test piece 10 to prevent it from falling off the pressure plate 9. The annular opening of the pressure plate 9 is smaller than the annular opening of the pressure plate 9, so the fixing plate 8 can act as a limiting plate to prevent the test piece 10 from falling off the fixing plate 8 end, and provide certain support when the test piece 10 is connected to the front adapter plate 11.

[0071] Next, the operator can rotate the rotating shaft 63 using the U-shaped handle 61, thereby controlling the collar end of the pull rod collar 62 to engage with the pull rod collar 62 on the pressure plate 9. In this way, the pressure plate 9 and the fixed plate 8 will be quickly locked together, firmly clamping the test piece 10 in the receiving cavity formed by the pressure plate 9 and the fixed plate 8.

[0072] Then, the operator can grasp and rotate the rotating handle 21. Since the rotating handle 21 is connected to the threaded rod 23, the rotation of the rotating handle 21 will drive the rotation of the threaded rod 23. At the same time, the limiting rod 22 limits the slider 24, allowing the slider 24 to slide linearly along the slide table. As the slider 24 slides, the moving plate 4 and its rib plate 5 will move together towards the wire harness box 3, connecting the test piece 10 and the front adapter plate 11. At the same time, the limiting hole 110 on the front adapter plate 11 cooperates with the pin to limit the rotation, preventing excessive rotation of the rotating handle 21, which could cause the test piece 10 to be squeezed between the front adapter plate 11 and cause damage.

[0073] After the test is completed, the operator can rotate the handle 21 in the opposite direction to move the moving plate 4 and its components away from the wire harness box 3, returning it to its initial position. Then, by rotating the U-shaped handle 61, the collar end of the pull rod collar 62 is disengaged from the pull rod collar 62 on the pressure plate 9, achieving quick unlocking between the pressure plate 9 and the fixed plate 8, thereby removing the test piece 10 for the next test or other operations.

[0074] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
