Description

Technical Field

[0001] This invention relates to the field of connector testing technology, specifically a connector insertion and removal life testing device and method. Background Technology

[0002] As crucial interface components in electronic devices, connectors' mating and extraction lifespan directly impacts the reliability and lifespan of the entire device. In practical use, connectors undergo frequent mating and extraction operations. Insufficient mating and extraction lifespan can easily lead to poor contact, signal transmission interruptions, and other problems, severely affecting device performance. Therefore, conducting scientific and accurate mating and extraction lifespan tests on connectors is of great significance.

[0003] Traditional connector insertion and removal testing equipment often uses simple linear reciprocating motion to simulate insertion and removal actions, which cannot realistically simulate actual situations such as angular deviations that may occur during human operation. This leads to significant differences between test results and actual use. In addition, existing equipment often lacks force control when clamping connectors, which can easily damage the connector due to excessive clamping or cause positional displacement during testing due to insufficient clamping, affecting test accuracy.

[0004] To address the above issues, an improved connector mating and extraction life testing device and method are now designed. Summary of the Invention

[0005] The purpose of this invention is to provide a connector insertion and removal life testing device and method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A connector insertion and removal life testing device includes a base box, a support frame mounted on the upper end of the base box, and first openings on two opposite side walls of the support frame. A host computer is mounted on the upper end of the support frame, and the host computer is equipped with a connector head that is connected to the male and female connectors of the connector via connecting wires. A movable frame is provided inside the support frame, with its open end facing one of the first openings. A second opening corresponding to the first opening is provided on the movable frame. Clamping mechanisms for clamping and fixing the male and female connectors of the connector are provided on the support frame and the movable frame respectively. A moving mechanism for reciprocating movement of the movable frame is provided on the base box.

[0007] As a further aspect of the present invention: the clamping mechanism includes two first electric push rods, which are respectively installed on the upper end of the base box at the top of the support frame and the bottom of the support frame on the open side of the moving frame. The output ends of the two first electric push rods are arranged opposite to each other. A first pressure sensor is installed on the output end of the first electric push rod. A first mounting plate is installed on the measuring end of the first pressure sensor. A first rubber clamping block for clamping and fixing the male or female head of the connector is detachably installed on the end of the first mounting plate away from the first electric push rod.

[0008] The movable frame has a second electric push rod vertically mounted on its top and bottom near the first electric push rod.

The end of the second mounting plate away from the second electric push rod is detachably equipped with a second rubber clamping block for clamping and fixing the male or female head of the connector. The movable frame between the second electric push rod and the second opening is provided with an offset component for slightly offsetting the connector clamped by the second rubber clamping block.

[0009] As a further embodiment of the present invention: the offset assembly includes two third electric push rods, which are respectively vertically mounted on the top and bottom of the movable frame between the second electric push rod and the second opening. The output end of the third electric push rod is equipped with a third pressure sensor, and the measuring end of the third pressure sensor is equipped with a third mounting plate. The end of the third mounting plate away from the third electric push rod is detachably equipped with a third rubber clamping block for pushing the connector to make a micro offset.

[0010] As a further embodiment of the present invention: the moving mechanism includes a screw, which is horizontally disposed inside the base box. The screw is parallel to the slide groove. A motor for driving the screw to rotate is installed at one end of the screw. The motor is installed inside the base box. The end of the screw away from the motor is rotatably connected to the inner wall of the base box. A moving block is rotatably connected to the side wall of the screw by a thread. The side wall of the moving block moves along the inner wall of the base box.

[0011] The upper end of the base box has a sliding groove along the insertion and removal direction of the connector. A slider is slidably connected to the inner wall of the sliding groove. The upper end of the slider is installed at the lower end of the moving frame, and the lower end of the slider is installed at the upper end of the moving block. A limit switch for stopping the motor is installed on the top of the base box near the first electric push rod. A camera for capturing the separation of the male and female connectors is provided between the first and second rubber clamping blocks. A fixing plate is installed at the bottom of the camera, and the upper end of the fixing plate is installed on the side wall of the bracket frame.

[0012] As a further embodiment of the present invention: a plurality of limiting rods are horizontally installed on the side wall of the movable frame away from the first electric push rod, the limiting rods are parallel to each other with the sliding groove, and a limiting cylinder that cooperates with the limiting rods is installed on the side wall of the support frame, the side wall of the limiting rods being slidably connected to the inner wall of the limiting cylinder.

[0013] As a further aspect of the present invention: the side wall of the movable block is equipped with ball bearings to facilitate the movement of the movable block along the inner wall of the base box.

[0014] As a further aspect of the present invention: the side wall of the movable frame is equipped with reinforcing support ribs to improve the structural strength of the movable frame and prevent deformation of the movable frame.

[0015] As a further aspect of the present invention: a rubber friction pad is installed at the lower end of the base box to facilitate stable placement of the base box.

[0016] As a further embodiment of the present invention: the bracket frame and the upper end of the base box are fixedly connected together by welding, and a triangular support rib is provided at the connection.

[0017] A method of using a connector mating and extraction life testing device includes the following steps: Step 1: First, connect the connecting wires to the male and female connectors respectively. Then, connect the male and female connectors together and place them between the two first rubber clamping blocks and the two second rubber clamping blocks respectively. Then, activate the first electric push rod. The output end of the first electric push rod drives the first pressure sensor to move. The first pressure sensor drives the first mounting plate to move. The first mounting plate drives the first rubber clamping blocks to move, so that the first rubber clamping blocks clamp the male connector. At the same time, the clamping force is measured by the first pressure sensor to avoid damaging the connector.

[0018] Simultaneously, the second electric push rod is activated. The output end of the second electric push rod drives the second pressure sensor to move. The second pressure sensor drives the second mounting plate to move. The second mounting plate drives the second rubber clamping block to move, so that the second rubber clamping block clamps the female end of the connector. At the same time, the clamping force is measured by the second pressure sensor to avoid damaging the connector.

[0019] Then, the connecting wires are passed through the first and second openings and connected to the connector head, so that the host computer can detect the insertion and removal connection of the male and female connectors, thereby recording the number of insertions and removals of the male and female connectors and calculating the service life of the connector.

[0020] Step 2: When offsetting the connector female head on the second rubber clamping block, the third electric push rod at the bottom of the moving frame is fully retracted, and the third electric push rod at the top of the moving frame is extended. The output end of the third electric push rod drives the third pressure sensor to move, the third pressure sensor drives the third mounting plate to move, and the third mounting plate drives the third rubber clamping block to move, so that the third rubber clamping block pushes the connector female head downward. At the same time, the pushing force is measured by the third pressure sensor, thereby controlling the offset of the connector female head. Conversely, the connector female head is offset upward.

[0021] Step 3: During testing, the motor is started. The motor's output drives the screw to rotate. Under the action of the screw thread, the screw drives the moving block to move along the inner wall of the base box and away from the limit switch. The moving block drives the slider to move, the slider drives the moving frame to move, and the moving frame drives the second electric push rod, the second pressure sensor, the second mounting plate, the second rubber clamping block, and the third electric push rod, the third pressure sensor, the third mounting plate, and the third rubber clamping block to move. This causes the second rubber clamping block to move the female head of the connector, separating the male and female heads of the connector. The separation of the male and female heads of the connector is captured by a camera. When the male and female heads of the connector are completely separated, the motor is started in reverse, causing the second rubber clamping block to move the female head of the connector, allowing the male and female heads of the connector to engage. When the moving block touches the limit switch, the male and female heads of the connector are fully engaged. Then the motor is started in reverse, and this process is repeated to continuously insert and remove the male and female heads of the connector. At the same time, the host computer records the number of insertions and removals of the connector, thus achieving the testing of the connector.

[0022] Step 4: When stopping, the moving block contacts the limit switch to complete the last insertion and removal. Then the limit switch sends a signal to the host computer to stop the motor, thereby stopping the moving block near the initial point of the motor.

[0023] Compared with the prior art, the beneficial effects of the present invention are: This invention uses two first rubber clamping blocks and two second rubber clamping blocks to clamp the male and female ends of the connector respectively. A first pressure sensor measures the clamping force of the first rubber clamping blocks, and a second pressure sensor measures the clamping force of the second rubber clamping blocks. This allows the first and second rubber clamping blocks to maintain the same clamping force for different connectors, improving the applicability of the device and protecting the connector.

[0024] This invention simulates the actual insertion and removal process by setting a third electric push rod at both the top and bottom of the moving frame, and then using the third electric push rod to push the connector on the second rubber clamping block to slightly shift, thereby improving the accuracy of connector insertion and removal testing. Compared with traditional linear insertion and removal testing, this invention is closer to actual operation and improves the accuracy of connector insertion and removal testing.

Clamping mechanisms for clamping and fixing the male and female connectors of the connector are provided on the support frame 16 and the movable frame 17 respectively. A moving mechanism for reciprocating movement of the movable frame 17 is provided on the base box 1.

[0032] The clamping mechanism includes two first electric push rods 15, which are respectively installed on the top of the support frame 16 on the open side of the movable frame 17 and on the upper end of the base box 1 at the bottom of the support frame 16. The output ends of the two first electric push rods 15 are arranged opposite to each other. A first pressure sensor 13 is installed on the output end of the first electric push rod 15. A first mounting plate 11 is installed on the measuring end of the first pressure sensor 13. A first rubber clamping block 10 for clamping and fixing the male or female head of the connector is detachably installed on the end of the first mounting plate 11 away from the first electric push rod 15.

[0033] The movable frame 17 has a second electric push rod 5 vertically mounted on its top and bottom near the first electric push rod 15. A second pressure sensor 6 is mounted on the output end of the second electric push rod 5. A second mounting plate 7 is mounted on the measuring end of the second pressure sensor 6. A second rubber clamping block 8 for clamping and fixing the male or female connector is detachably mounted on the end of the second mounting plate 7 away from the second electric push rod 5. An offset component for slightly offsetting the connector clamped by the second rubber clamping block 8 is provided inside the movable frame 17 between the second electric push rod 5 and the second opening 22.

[0034] In use, the male and female connectors are joined together and then placed between two first rubber clamping blocks 10 and two second rubber clamping blocks 8 respectively. Then, the first electric push rod 15 is activated. The output end of the first electric push rod 15 drives the first pressure sensor 13 to move. The first pressure sensor 13 drives the first mounting plate 11 to move. The first mounting plate 11 drives the first rubber clamping blocks 10 to move, so that the first rubber clamping blocks 10 clamp the male or female connector. At the same time, the clamping force is measured by the first pressure sensor 13 to avoid damaging the connector.

[0035] Simultaneously, the second electric push rod 5 is activated. The output end of the second electric push rod 5 drives the second pressure sensor 6 to move. The second pressure sensor 6 drives the second mounting plate 7 to move. The second mounting plate 7 drives the second rubber clamping block 8 to move, so that the second rubber clamping block 8 clamps the male or female end of the connector. At the same time, the clamping force is measured by the second pressure sensor 6 to avoid damaging the connector.

[0036] The offset assembly includes two third electric push rods 4, which are vertically mounted on the top and bottom of the movable frame 17 between the second electric push rod 5 and the second opening 22, respectively. A third pressure sensor 25 is installed at the output end of the third electric push rod 4, and a third mounting plate 24 is installed at the measuring end of the third pressure sensor 25. A third rubber clamping block 23 for pushing the connector to make micro-offsets is detachably installed at the end of the third mounting plate 24 away from the third electric push rod 4.

[0037] When the connector needs to be offset downwards, the third electric push rod 4 at the bottom of the moving frame 17 retracts completely, and the third electric push rod 4 at the top of the moving frame 17 extends. The output end of the third electric push rod 4 drives the third pressure sensor 25 to move. The third pressure sensor 25 drives the third mounting plate 24 to move. The third mounting plate 24 drives the third rubber clamping block 23 to move, so that the third rubber clamping block 23 pushes the male or female head of the connector. At the same time, the third pressure sensor 25 measures the pushing force, thereby controlling the offset of the male or female head of the connector. Conversely, it causes the connector to offset upwards.

[0038] The moving mechanism includes a screw 29, which is horizontally disposed inside the base box 1 and parallel to the slide groove 2. One end of the screw 29 is equipped with a motor 26 for driving the screw 29 to rotate. The motor 26 is installed inside the base box 1. The end of the screw 29 away from the motor 26 is rotatably connected to the inner wall of the base box 1. The side wall of the screw 29 is rotatably connected to a moving block 28 by a thread. The side wall of the moving block 28 moves along the inner wall of the base box 1.

[0039] The upper end of the base box 1 is provided with a sliding groove 2 along the insertion and removal direction of the connector. A slider 3 is slidably connected to the inner wall of the sliding groove 2. The upper end of the slider 3 is installed at the lower end of the moving frame 17, and the lower end of the slider 3 is installed at the upper end of the moving block 28. A limit switch 27 for stopping the motor 26 is installed on the top of the base box 1 near the first electric push rod 15. A camera 9 for capturing the separation of the male and female connectors is provided between the first rubber clamping block 10 and the second rubber clamping block 8. A fixing plate 14 is installed at the bottom of the camera 9, and the upper end of the fixing plate 14 is installed on the side wall of the bracket frame 16.

[0040] A plurality of limiting rods 19 are horizontally installed on the side wall of the movable frame 17 away from the first electric push rod 15. The limiting rods 19 are parallel to the slide groove 2. A limiting cylinder 21 that cooperates with the limiting rods 19 is installed on the side wall of the support frame 16. The side wall of the limiting rod 19 is slidably connected to the inner wall of the limiting cylinder 21.

[0041] When in use, the motor 26 is started, and the output end of the motor 26 drives the screw 29 to rotate. Under the action of the screw, the screw 29 drives the moving block 28 to move along the inner wall of the base box 1. The moving block 28 drives the slider 3 to move, the slider 3 drives the moving frame 17 to move, and the moving frame 17 drives the second electric push rod 5, the second pressure sensor 6, the second mounting plate 7, the second rubber clamping block 8, the third electric push rod 4, the third pressure sensor 25, the third mounting plate 24, and the third rubber clamping block 23 to move, thereby causing the second rubber clamping block 8 to drive the connector male or female head to move.

[0042] Working principle of a connector mating and extraction life testing device and method: Before testing, connect the connecting wires to the male and female connectors respectively. Then, connect the male and female connectors together and place them between the two first rubber clamping blocks 10 and the two second rubber clamping blocks 8 respectively. Then, start the first electric push rod 15. The output end of the first electric push rod 15 drives the first pressure sensor 13 to move. The first pressure sensor 13 drives the first mounting plate 11 to move. The first mounting plate 11 drives the first rubber clamping blocks 10 to move, so that the first rubber clamping blocks 10 clamp the male connector. At the same time, the clamping force is measured by the first pressure sensor 13 to avoid damaging the connector.

[0043] At the same time, the second electric push rod 5 is activated. The output end of the second electric push rod 5 drives the second pressure sensor 6 to move. The second pressure sensor 6 drives the second mounting plate 7 to move. The second mounting plate 7 drives the second rubber clamping block 8 to move, so that the second rubber clamping block 8 clamps the female end of the connector. At the same time, the clamping force is measured by the second pressure sensor 6 to avoid damaging the connector.

[0044] Then, the connecting wires are passed through the first opening 12 and the second opening 22 and connected to the connector 20, so that the host computer 18 can detect the insertion and removal connection of the male and female connectors, thereby recording the number of insertions and removals of the male and female connectors and calculating the service life of the connector.

[0045] When the connector female head on the second rubber clamping block 8 is offset, the third electric push rod 4 at the bottom of the starting moving frame 17 is fully retracted, and the third electric push rod 4 at the top of the starting moving frame 17 is extended. The output end of the third electric push rod 4 drives the third pressure sensor 25 to move. The third pressure sensor 25 drives the third mounting plate 24 to move. The third mounting plate 24 drives the third rubber clamping block 23 to move, so that the third rubber clamping block 23 pushes the connector female head downward. At the same time, the pushing force is measured by the third pressure sensor 25, thereby controlling the offset of the connector female head. Conversely, the connector female head is offset upward.

[0046] During testing, motor 26 is started, and its output drives screw 29 to rotate. Under the action of the thread, screw 29 drives moving block 28 to move along the inner wall of base box 1 and away from limit switch 27. Moving block 28 drives slider 3 to move, slider 3 drives moving frame 17 to move, and moving frame 17 drives second electric push rod 5, second pressure sensor 6, second mounting plate 7, second rubber clamping block 8, and third electric push rod 4, third pressure sensor 25, third mounting plate 24, and third rubber clamping block 23 to move, thereby causing second rubber clamping block 8 to drive connector. The female head moves, separating the male and female heads of the connector. The separation is captured by camera 9. Once the male and female heads are completely separated, motor 26 reverses, causing the second rubber clamping block 8 to move the female head of the connector, allowing the male and female heads to engage. When the moving block 28 touches the limit switch 27, the male and female heads are fully engaged. Then, motor 26 reverses, and this process is repeated to continuously insert and remove the male and female heads of the connector. Simultaneously, the host computer 18 records the number of insertions and removals, thus testing the connector.

[0047] When stopped, the moving block 28 contacts the limit switch 27 to complete the last insertion and removal, and then the limit switch 27 sends a signal to the host computer 18 to stop the motor 26, thereby stopping the moving block 28 at the initial point close to the motor 26.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

10. A method of using the connector mating and extraction life testing equipment according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: First, connect the connecting wires to the male and female connectors respectively. Then, connect the male and female connectors together and place them between the two first rubber clamping blocks (10) and the two second rubber clamping blocks (8). Then, start the first electric push rod (15). The output end of the first electric push rod (15) drives the first pressure sensor (13) to move. The first pressure sensor (13) drives the first mounting plate (11) to move. The first mounting plate (11) drives the first rubber clamping block (10) to move, so that the first rubber clamping block (10) clamps the male connector. At the same time, the clamping force is measured by the first pressure sensor (13) to avoid damaging the connector. At the same time, the second electric push rod (5) is activated. The output end of the second electric push rod (5) drives the second pressure sensor (6) to move. The second pressure sensor (6) drives the second mounting plate (7) to move. The second mounting plate (7) drives the second rubber clamping block (8) to move, so that the second rubber clamping block (8) clamps the female end of the connector. At the same time, the clamping force is measured by the second pressure sensor (6) to avoid damaging the connector. Then, the connecting wire is passed through the first opening (12) and the second opening (22) and connected to the connector (20), so that the host computer (18) can detect the insertion and removal connection of the male and female connectors, thereby the host computer (18) records the number of insertions and removals of the male and female connectors, and then calculates the service life of the connector. Step 2: When the connector female head on the second rubber clamping block (8) is offset, the third electric push rod (4) at the bottom of the moving frame (17) is fully retracted, and the third electric push rod (4) at the top of the moving frame (17) is extended. The output end of the third electric push rod (4) drives the third pressure sensor (25) to move. The third pressure sensor (25) drives the third mounting plate (24) to move. The third mounting plate (24) drives the third rubber clamping block (23) to move, so that the third rubber clamping block (23) pushes the connector female head downward. At the same time, the pushing force is measured by the third pressure sensor (25) to control the offset of the connector female head. Conversely, the connector female head is offset upward. Step 3: During testing, start the motor (26). The output end of the motor (26) drives the screw (29) to rotate. Under the action of the screw thread, the screw (29) drives the moving block (28) to move along the inner wall of the base box (1) and away from the limit switch (27). The moving block (28) drives the slider (3) to move. The slider (3) drives the moving frame (17) to move. The moving frame (17) drives the second electric push rod (5), the second pressure sensor (6), the second mounting plate (7), the second rubber clamping block (8), and the third electric push rod (4), the third pressure sensor (25), the third mounting plate (24), and the third rubber clamping block (23) to move, thereby... The second rubber clamping block (8) moves the female head of the connector, causing the male and female heads of the connector to separate. The separation of the male and female heads of the connector is captured by the camera (9). When the male and female heads of the connector are completely separated, the motor (26) is started to reverse, causing the second rubber clamping block (8) to move the female head of the connector, causing the male and female heads of the connector to mate. When the moving block (28) touches the limit switch (27), the male and female heads of the connector are fully mate. Then the motor (26) is started to reverse, and so on, continuously inserting and removing the male and female heads of the connector. At the same time, the host computer (18) records the number of times the connector is inserted and removed, thus realizing the testing of the connector. Step 4: When stopping, the moving block (28) contacts the limit switch (27) to complete the last plugging and unplugging. Then the limit switch (27) sends a signal to the host computer (18) to stop the motor (26), thereby stopping the moving block (28) at the initial point close to the motor (26).
