Description

Technical Field

[0001] This invention relates to the field of connector processing technology, specifically to a fitting and method for testing insertion and extraction force in connector processing. Background Technology

[0002] Connectors are used in the channel connector assemblies of megawatt-level transmitters, handling low-loss transmission of high-frequency (typically from tens of MHz to GHz) high-power radio frequency signals. In continuous operation scenarios such as television, broadcasting, and radar, even minute contact resistances can be converted into enormous amounts of heat, thus placing stringent requirements on their materials and structures.

[0003] During connector manufacturing, mating tests are essential to verify their mechanical lifespan and electrical reliability. These tests involve repeatedly inserting and removing the connector using test fixtures, simulating the wear and tear process encountered in real-world use. Key monitoring indicators include: insertion and extraction force (assessing the smoothness of operation), contact resistance (detecting sudden changes in resistance due to fretting wear or stress relaxation), and insulation withstand voltage performance. The tests typically involve hundreds to thousands of cycles (e.g., 500 cycles) to verify the effectiveness of the locking mechanism and the stability of signal transmission after long-term use.

[0004] The connector includes a male plug and a female plug, each comprising a housing 1002 and a connector 1001 attached to the end of the housing 1002. The connector 1001 has multiple connection holes and a square cross-section. The insertion and extraction force is detected by testing the insertion and disconnection of the two housings 1002. Currently, testing typically involves fixing the male and female plugs separately using two clamps. After testing, the clamps must be loosened to disassemble the male and female plugs, a cumbersome and time-consuming process that reduces testing efficiency. Furthermore, due to the variety of connector specifications, traditional clamps are difficult to adapt to different sizes of male and female plugs, resulting in poor versatility and a need for improved applicability. Summary of the Invention

[0005] The purpose of this invention is to provide a testing fixture and method for testing insertion and extraction force in connector processing, which has a wider range of applications, enables continuous testing of multiple connectors, improves work efficiency, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a connector processing insertion and extraction force testing fixture, comprising a support platform and a side plate connected to the top of the support platform. A rotating disk is rotatably connected to the top of the support platform. The rotating disk is provided with multiple placement slots for placing products, and a positioning mechanism for product positioning is connected inside the rotating disk. The positioning mechanism includes a gear plate, four push-pull plates, and four clamping blocks. The two ends of the push-pull plates are connected to the clamping blocks and the gear plate. A liftable lifting plate is connected to the side plate. The lifting plate is connected to a clamping seat, a pressing plate, and a pressing cylinder. The clamping seat is aligned with the corresponding placement slot. The pressing plate is used to drive the gear plate to rotate. A limiting mechanism for limiting the rotation of the rotating disk is connected to the support platform. The pressing cylinder is used to open the limiting mechanism. A motor is connected to the bottom of the support platform, and the power output end of the motor is connected to the rotating disk.

[0007] Preferably, the positioning mechanism further includes a gear, a bevel gear, and four movable plates. The gear is connected to the bevel gear via a shaft, the bevel gear meshes with a gear disk, the gear disk is rotatably connected within a rotating disk, one end of the movable plate is fixedly connected to a pressing block, and the other end is connected to a push-pull plate via a shaft. The push-pull plate is axially connected to the gear disk, and the movable plate is slidably connected to the rotating disk.

[0008] Preferably, the pressing plate is slidably connected to a toothed plate, and a second spring is connected to the top of the toothed plate, with the end of the second spring connected to the pressing plate.

[0009] Preferably, the clamping seat is provided with a sliding groove and a limiting surface, and a connecting frame is slidably connected to the front end of the clamping seat. Both ends of the connecting frame are connected to blocks. The clamping seat is fixed with two spring seats, and a guide post is fixed to each spring seat. The guide post is slidably connected to the connecting frame, and the guide post is provided with a spring for driving the block to descend.

[0010] Preferably, the spring is fitted onto the guide post, and both ends of the spring are connected to the spring seat and the connecting frame.

[0011] Preferably, the limiting mechanism includes a support, a rocker, a positioning post, and a spring. The support is connected to the bottom of the support platform, the rocker is connected to the support via a shaft, the positioning post is slidably connected to the support platform, and the spring is used to drive the positioning post to move downward.

[0012] Preferably, the bottom of the rotating disk is provided with multiple positioning grooves, the top of the positioning post is connected to the positioning groove, the spring four is sleeved on the positioning post, and the two ends of the spring four are connected to the support platform and the positioning post, the pressing cylinder is slidably connected to the pressing post, the top of the pressing post is connected to the spring three, and the end of the spring three is connected to the pressing cylinder.

[0013] Preferably, a positioning cylinder is connected to the outer side of the side plate, and a positioning block is connected to the power output end of the positioning cylinder. The positioning block matches the limiting groove set in the gear, and the cross-section of the limiting groove is a regular polygonal structure.

[0014] Preferably, a cylinder is connected to the top of the side plate, the power output end of the cylinder is connected to the lifting plate, the lifting plate is slidably connected to the side plate, and a pressure sensor is connected to the bottom of the lifting plate. The pressure sensor is detachably connected to the clamping seat, and a PLC controller and a display are connected to the inside of the side plate. The pressure sensor, the display and the PLC controller are electrically connected.

[0015] A testing method for a connector processing insertion and extraction force testing fixture includes the following steps:

[0016] Step 1: Place multiple male plugs into the corresponding slots, then insert the female plug into the clamping seat, and then release the connecting frame. The compressed spring pushes the connecting frame down, which in turn drives the two stops down. The stops connect with the female plug to limit the position of the female plug.

[0017] Step 2: The cylinder drives the lifting plate, pressure sensor, clamping seat, and female plug to descend synchronously, while the pressing plate, toothed plate, pressing cylinder, and pressing column also descend. The pressing column presses against one end of the rocker, causing the other end of the rocker to be lifted, which in turn pushes the positioning column upward. The top of the positioning column is inserted into the positioning groove, which limits and fixes the rotating disk, facilitating subsequent testing. At this time, the toothed plate is not in contact with the gear. The lifting plate continues to descend, the spring is compressed, and the toothed plate drives the gear to rotate. The gear drives the bevel gear to rotate, and the bevel gear drives the gear disk to rotate, applying a pushing force to the four push-pull plates simultaneously, pushing the clamping blocks forward, so that the four clamping blocks press against the outside of the male plug, achieving positioning and fixing of the male plug, making the male plug and female plug concentric, which facilitates subsequent insertion of the two.

[0018] Step 3: The female plug is then connected to the male plug. The pressure sensor detects the maximum peak value of the insertion force, which is the insertion force of the connector. The positioning cylinder then drives the positioning block forward, connecting it with the limiting groove inside the front gear, thus locking the gear plate. The cylinder drives the lifting plate, pressure sensor, clamping seat, and female plug upwards, gradually releasing spring three. However, the positioning pin remains connected to the positioning groove, thus limiting the rotation of the disc. Meanwhile, spring two gradually releases, the gear plate position remains unchanged, and the female and male connectors disconnect. The pressure sensor then detects the maximum peak value of the insertion force. The value represents the pull-out force of the connector. The pull-out force is displayed on the monitor for easy observation and recording. After the test is completed, the positioning cylinder drives the positioning block to move backward, thereby loosening the gear. The lifting plate pulls the pressing plate, toothed plate, pressing cylinder, and pressing column upward, which in turn drives the toothed disc to rotate, causing the four clamping blocks to move back synchronously, thereby loosening the female plug. The motor continues to drive the rotating disc to rotate, so that the next female plug is located below the clamping seat. Another male plug is then inserted and connected to the clamping seat. The above test operation is repeated, thereby enabling continuous testing of multiple connectors and improving work efficiency.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, by setting a positioning mechanism and a limiting mechanism, places multiple male plugs into corresponding placement slots. The cylinder drives the lifting plate to descend, which simultaneously drives the pressing cylinder, pressing column, pressing plate and toothed plate to descend. The pressing column presses against one end of the rocker, that is, the other end of the rocker lifts up, so that the positioning column moves up and connects with the positioning slot, thereby achieving effective positioning and fixing of the rotating disk, which is beneficial to subsequent testing operations. The toothed plate drives the gear to rotate, and in conjunction with the bevel gear, toothed disc, four push-pull plates, and moving plate, the four clamping blocks move synchronously toward the center of the placement slot, thereby locking and fixing the male plug and achieving centering for precise docking with the female plug. The springs allow the four clamping blocks to press the male plugs of different sizes, making it more versatile. Then the female plug connects to the male plug, and the pressure sensor detects the maximum peak value of the insertion force. When the lifting plate moves up, the female and male connectors disconnect, and the pressure sensor detects the maximum peak value of the insertion force, which is the pull-out force of the connector. The insertion and pull-out force is displayed on the monitor for easy observation and recording. Furthermore, it enables continuous testing of multiple connectors, improving work efficiency and making it highly practical. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 11This invention provides a connector processing insertion and extraction force testing fixture, including a support platform 1 and a side plate 2 connected to the top of the support platform 1. A rotating disk 7 is rotatably connected to the top of the support platform 1 to improve the rotational stability of the rotating disk 7. The rotating disk 7 is provided with multiple placement slots 8 for placing products, and the cross-section of the placement slots 8 is a square structure. A positioning mechanism for product positioning is connected inside the rotating disk 7. The positioning mechanism includes a toothed disk 31, four push-pull plates 33, and four clamping blocks 22. The two ends of the push-pull plates 33 are connected to the clamping blocks 22 and the toothed disk 31. A liftable lifting plate 4 is connected to the side plate 2. The lifting plate 4 is connected to a clamping seat 6, a pressing plate 10, and a pressing cylinder 12. The clamping seat 6 is aligned with the corresponding placement slot 8. The pressing plate 10 is used to drive the toothed disk 31 to rotate. A limiting mechanism for limiting the rotation disk 7 is connected to the support platform 1. The pressing cylinder 12 is used to open the limiting mechanism. A motor 25 is connected to the bottom of the support platform 1, and the power output end of the motor 25 is connected to the rotating disk 7.

[0034] There are typically four placement slots 8, with adjacent slots forming a 90° angle. When a placement slot 8 moves directly below the clamping seat 6, it is in the testing position. Multiple male plugs are placed in their respective placement slots 8. The cylinder 3 drives the lifting plate 4 to descend, simultaneously lowering the pressure sensor 5, clamping seat 6, pressing plate 10, toothed plate 11, pressing cylinder 12, and pressing column 13. The bottom of the pressing column 13 passes through the support platform 1 and presses against one end of the rocker arm 27, causing them to slide relative to each other. The other end of the rocker arm 27 lifts up, thus lifting the positioning column 28. Spring 4 29 is compressed, and spring 3 21 is also compressed. The positioning column 28 connects to the positioning slot 30, locking and fixing the rotating disk 7 for subsequent testing. Furthermore, before the toothed plate 11 contacts the gear 9, the lifting plate 4 continues to descend, the spring 21 continues to compress, the position of the positioning post 28 remains unchanged, the toothed plate 11 drives the gear 9 to rotate, the gear 9 drives the conical tooth 32 to rotate, the conical tooth 32 drives the gear disk 31 to rotate, the gear disk 31 applies a pushing force to the four push-pull plates 33 simultaneously, causing the push-pull plates 33 to push the moving plate 34 and the clamping block 22 forward, that is, the four clamping blocks 22 move synchronously towards the center of the placement slot 8, and the four clamping blocks 22 press against the four outer sides of the male plug connector seat 1001, thereby locking and fixing the male plug. Of course, the spring 20 is in a compressed state, thus satisfying the limit of male plugs of different sizes, making it highly applicable. Then the lifting plate 4 descends further, allowing the male plugs to be inserted into each other, and the pressure sensor 5 detects the maximum peak value of the insertion force, which is the insertion force of the connector. Then, the positioning cylinder 35 drives the positioning block 36 forward, connecting the positioning block 36 with the limiting groove 37 of the gear 9, thus positioning the gear 9 and fixing the male plug. Immediately, the lifting plate 4 moves upward, separating the female plug from the male plug. The pressure sensor 5 detects the maximum peak value of the insertion force, which is the pull-out force of the connector. During this process, the compression spring 21 rebounds a short distance, but the bottom of the pressing post 13 remains pressed against the rocker plate 27, meaning the positioning post 28 and the positioning groove 30 are connected, still limiting the rotation of the rotating disk 7.

[0035] The positioning mechanism also includes a gear 9, a bevel gear 32, and four movable plates 34. The gear 9 is connected to the bevel gear 32 via a shaft, and the bevel gear 32 meshes with the gear disc 31, resulting in high transmission efficiency and ensuring a constant instantaneous transmission ratio. The gear disc 31 is rotatably connected within the rotating disk 7, ensuring stable rotation of the gear disc 31 and guaranteeing the transmission effect between the gear disc 31 and the bevel gear 32. One end of the movable plate 34 is fixedly connected to the clamping block 22, and the other end is connected to the push-pull plate 33 via a shaft. The push-pull plate 33 is axially connected to the gear disc 31, and the movable plate 34 is slidably connected to the rotating disk 7.

[0036] The rotation direction of the gear disk 31 is Figure 11The center arrow indicates that a pushing force will be applied simultaneously to the four moving plates 34, pushing the clamping block 22 forward to facilitate the positioning of the tolerance head. Furthermore, the inner surface of the clamping block 22 is made of non-slip rubber, which increases the friction with the tolerance head, prevents slippage, and provides good limiting for the tolerance head.

[0037] The pressing plate 10 is slidably connected to the toothed plate 11, and the top of the toothed plate 11 is connected to the spring 20, the end of the spring 20 being connected to the pressing plate 10.

[0038] The clamping seat 6 is equipped with a sliding groove 18 and a limiting surface 19. A connecting frame 15 is slidably connected to the front end of the clamping seat 6, and stops 14 are connected to both ends of the connecting frame 15. Two spring seats 17 are fixed to the clamping seat 6, and guide posts are fixed to the spring seats 17. The guide posts are slidably connected to the connecting frame 15, and springs 16 are provided on the guide posts to drive the stops 14 downwards. When inserting the busbar into the busbar slot, the connecting frame 15 is manually lifted, simultaneously moving the two stops 14 upwards, exposing the front end of the sliding groove 18. At this time, spring 16 is compressed. Then, the female plug is inserted into the clamping seat 6, connecting the female plug's connecting seat 1001 to the sliding groove 18, while the outer shell 1002 rests against the limiting surface 19. The female plug is then positioned and moved. The connecting frame 15 is then released, and the compressed spring 16 drives the connecting frame 15 and the two stops 14 to descend simultaneously, connecting the stops 14 to the front end of the connecting seat 1001, achieving good positioning of the female plug. The operation is simple, convenient, and efficient.

[0039] Spring 16 is fitted onto the guide post, and both ends of spring 16 are connected to spring seat 17 and connecting frame 15.

[0040] The limiting mechanism includes a support 26, a rocker 27, a positioning post 28, and a spring 29. The support 26 is connected to the bottom of the support platform 1. The rocker 27 is connected to the support 26 via a shaft. The positioning post 28 is slidably connected to the support platform 1. The spring 29 is used to drive the positioning post 28 to move downward.

[0041] By applying pressure to one end of the rocker 27, the other end is driven to tilt upwards, thereby lifting the positioning pin 28 and connecting it with the corresponding positioning groove 30, thus locking the rotating disk 7 in place. Conversely, when the pressure is released from one end of the rocker 27, i.e., the pressing pin 13 separates from the rocker 27, the compressed spring 4 29 pushes the positioning pin 28 downwards, separating the positioning pin 28 from the positioning groove 30, thus releasing the rotating disk 7.

[0042] The bottom of the rotating disk 7 is provided with multiple positioning slots 30. The top of the positioning post 28 is connected to the positioning slot 30. There are four positioning slots 30 in total, and each positioning slot 30 corresponds to a single placement slot 8. Spring 4 29 is sleeved on the positioning post 28, and both ends of spring 4 29 are connected to the support platform 1 and the positioning post 28. Pressing cylinder 12 is slidably connected to pressing post 13. Spring 3 21 is connected to the top of pressing post 13, and the end of spring 3 21 is connected to pressing cylinder 12.

[0043] A positioning cylinder 35 is connected to the outer side of the side plate 2. A positioning block 36 is connected to the power output end of the positioning cylinder 35. The positioning block 36 matches the limiting groove 37 set in the gear 9. The limiting groove 37 has a regular polygonal cross-section. The positioning cylinder 35 drives the positioning block 36 to move back, so that the positioning block 36 separates from the limiting groove 37, thereby loosening the gear 9. The lifting plate 4 moves up, driving the gear plate 11 to move up. The gear 9 rotates, causing the four clamping blocks 22 to move back synchronously, thereby loosening the male plug. The rotating disk 7 is also in a loosened state.

[0044] Then, the rotating disk 7 is driven by motor 25 to perform testing on the next connector.

[0045] A cylinder 3 is connected to the top of side plate 2. The power output end of cylinder 3 is connected to lifting plate 4. Lifting plate 4 is slidably connected to side plate 2, and a pressure sensor 5 is connected to the bottom of lifting plate 4. Pressure sensor 5 is detachably connected to clamping seat 6, usually by snap-fit, to facilitate the installation and removal of clamping seat 6 and to meet the positioning requirements of female plugs of different sizes. A PLC controller 23 and a display 24 are connected to the inside of side plate 2. Pressure sensor 5, display 24 and PLC controller 23 are electrically connected. Pressure sensor 5 collects insertion and extraction force data in real time and feeds it back to PLC controller 23 for processing. PLC compares the measured value with a preset range (21-30N), and the result is displayed intuitively on display 24. When the insertion and extraction force is less than 21N or greater than 30N, the system determines that the connector is unqualified; only when the force is between 21N and 30N is the product qualified. This process realizes automatic monitoring and visual management of connector quality.

[0046] A testing method for a connector processing insertion and extraction force testing fixture includes the following steps:

[0047] Step 1: Place multiple male plugs into the corresponding placement slots 8, then insert the female plug into the clamping seat 6, and then release the connecting frame 15. The compressed spring 16 pushes the connecting frame 15 down, which in turn drives the two stops 14 down. The stops 14 are connected to the female plug to limit the position of the female plug.

[0048] Step 2: Cylinder 3 drives the lifting plate 4, pressure sensor 5, clamping seat 6, and female plug to descend synchronously, while pressing plate 10, toothed plate 11, pressing cylinder 12, and pressing column 13 also descend. Pressing column 13 presses against one end of rocker plate 27, causing the other end of rocker plate 27 to be lifted, thereby pushing positioning column 28 to move upward. The top of positioning column 28 is inserted into positioning groove 30, realizing the limiting and fixing of rotating disk 7, which facilitates subsequent testing operations. At this time, toothed plate 11 is not in contact with gear 9. Lifting plate 4 continues to descend, spring 3 21 is compressed, and toothed plate 11 drives gear 9 to rotate. Gear 9 drives conical tooth 32 to rotate. Conical tooth 32 drives toothed disk 31 to rotate, simultaneously applying a pushing force to four push-pull plates 33, pushing pressing block 22 forward, so that the four pressing blocks 22 are pressed against the outside of male plug, realizing the positioning and fixing of male plug, making male plug and female plug concentric, which facilitates subsequent insertion of the two.

[0049] Step 3: The female plug is then connected to the male plug. Pressure sensor 5 detects the maximum peak value of the insertion force, which is the insertion force of the connector. Positioning cylinder 35 then drives positioning block 36 forward, connecting positioning block 36 with the limiting groove 37 inside the front gear 9, thus locking the gear plate 31. Cylinder 3 drives lifting plate 4, pressure sensor 5, clamping seat 6, and female plug upwards. Spring 3 21 gradually loosens, but positioning pin 28 remains connected to positioning groove 30, thus still limiting the rotation disk 7. Spring 2 20 gradually loosens, the position of gear plate 11 remains unchanged, the female and male connectors disconnect, and pressure sensor 5 detects the maximum insertion force. The peak value is the pull-out force of the connector. The pull-out force is displayed on the display 24 for easy observation and recording. After the test is completed, the positioning cylinder 35 drives the positioning block 36 to move backward, thereby loosening the gear 9. The lifting plate 4 pulls the pressing plate 10, the toothed plate 11, the pressing cylinder 12 and the pressing column 13 upward, which in turn drives the toothed disc 31 to rotate, so that the four clamping blocks 22 move back synchronously, thereby loosening the female plug. The motor 25 continues to drive the rotating disc 7 to rotate, so that the next female plug is located below the clamping seat 6. Another male plug is then inserted and connected to the clamping seat 6. The above test operation is repeated, thereby realizing continuous testing of multiple connectors and improving work efficiency.

The insertion / extraction force testing fixture for connector processing according to claim 2, characterized in that, A positioning cylinder (35) is connected to the outer side of the side plate (2). A positioning block (36) is connected to the power output end of the positioning cylinder (35). The positioning block (36) matches the limiting groove (37) set in the gear (9). The cross-section of the limiting groove (37) is a regular polygonal structure.

9. The insertion / extraction force testing fixture for connector processing according to claim 1, characterized in that, A cylinder (3) is connected to the top of the side plate (2). The power output end of the cylinder (3) is connected to the lifting plate (4). The lifting plate (4) is slidably connected to the side plate (2). A pressure sensor (5) is connected to the bottom of the lifting plate (4). The pressure sensor (5) is detachably connected to the clamping seat (6). A PLC controller (23) and a display (24) are connected to the inside of the side plate (2). The pressure sensor (5), the display (24) and the PLC controller (23) are electrically connected.

10. The test method for the connector processing insertion and extraction force testing fixture according to any one of claims 1 to 9, characterized in that, Includes the following steps: Step 1: Place multiple male plugs into the corresponding placement slots (8), then insert the female plug into the clamping seat (6), and then release the connecting frame (15). The compressed spring (16) pushes the connecting frame (15) down, simultaneously driving the two stops (14) down. The stops (14) connect with the female plug to limit the position of the female plug. Step 2: The cylinder (3) drives the lifting plate (4), pressure sensor (5), clamping seat (6), and female plug to descend synchronously, while the pressing plate (10), toothed plate (11), pressing cylinder (12), and pressing column (13) also descend. The pressing column (13) presses against one end of the rocker (27), causing the other end of the rocker (27) to be lifted, thereby pushing the positioning column (28) upward. The top of the positioning column (28) is inserted into the positioning groove (30), thereby limiting and fixing the rotating disk (7) to facilitate subsequent testing operations. When the toothed plate (11) is not in contact with the gear (9), the lifting plate (4) continues to descend, the spring three (21) is compressed, and the toothed plate (11) drives the gear (9) to rotate. The gear (9) drives the bevel tooth (32) to rotate, and the bevel tooth (32) drives the gear disc (31) to rotate, which simultaneously applies a thrust to the four push-pull plates (33), pushing the clamping block (22) forward, so that the four clamping blocks (22) are pressed against the outside of the male plug, thereby fixing the male plug and making the male plug and female plug concentric, which facilitates the subsequent insertion of the two. Step 3: The female plug is then connected to the male plug. The pressure sensor (5) will detect the maximum peak value of the insertion force, which is the insertion force of the connector. Then the positioning cylinder (35) drives the positioning block (36) to move forward, so that the positioning block (36) is connected to the limiting groove (37) in the front gear (9), thereby locking the gear plate (31). The cylinder (3) drives the lifting plate (4), pressure sensor (5), clamping seat (6), and female plug to move upward. Spring 3 (21) gradually loosens, but the positioning pin (28) is still connected to the positioning groove (30) to limit the rotating disk (7). Spring 2 (20) gradually loosens, the position of the gear plate (11) remains unchanged, the female connector and the male connector are disconnected, and the pressure sensor (5) will detect the insertion force. The maximum peak value is the pull-out force of the connector. The pull-out force is displayed on the display (24) for easy observation and recording. After the test is completed, the positioning cylinder (35) drives the positioning block (36) to move backward, thereby loosening the gear (9). The lifting plate (4) pulls the pressing plate (10), toothed plate (11), pressing cylinder (12) and pressing column (13) to move upward, thereby driving the toothed plate (31) to rotate, so that the four clamping blocks (22) move back synchronously, thereby loosening the female plug. The motor (25) continues to drive the rotating disk (7) to rotate, so that the next female plug is located below the clamping seat (6), and another male plug is inserted and connected to the clamping seat (6). The above test operation is repeated, thereby realizing continuous testing of multiple connectors and improving work efficiency.
