Description

Technical Field

[0001] The invention relates to the technical field of detection devices, in particular to a connectivity detection device for a connector and a flat wire harness. Background Art

[0002] Flexible cable is a type of cable that can withstand frequent bending, movement or twisting, and is often used in complex equipment connections and dynamic environments. It is light, thin, micro and flexible, suitable for electrical connections between various devices and components, ensuring the normal transmission of power supply, power signals, communication signals, etc. The key characteristics of flexible cables include their excellent vibration and impact resistance, as well as their ability to work stably in harsh environments. Flexible cables usually connect multiple sets of plugs and sockets, and achieve a stable connection through mechanical locking and electrical interfaces. The mechanical structure of plugs, sockets and cables needs to be designed according to the application environment to ensure reliable physical and electrical performance.

[0003] In the connectivity test of connectors and flat harnesses, the measurement of electrical variables mainly includes parameters such as resistance, voltage and current. By measuring resistance, it is possible to determine whether there is a poor contact or a circuit break at the contact point, while the measurement of voltage and current is used to evaluate the stability and load capacity of the circuit under different working conditions. The changes in these electrical parameters can reflect the performance of connectors and harnesses during plug-in and unplug operations, thereby providing a basis for testing reliability and durability.

[0004] The measurement of electrical variables of connectors and flat harnesses usually requires multiple plugging and unplugging operations to evaluate their durability, contact stability, and fatigue resistance in long-term use. However, multiple manual plugging and unplugging operations are not only cumbersome and time-consuming, but also increase human errors and make it difficult to ensure the consistency of each operation. Human factors such as the force, angle, and speed of plugging and unplugging may cause inaccuracies, thereby affecting the reliability of the test results.

A positioning column is provided on the top of the lower clamping plate 21 for limiting the connector of the flat wiring harness 5. The inner wall of the horizontal platform 26 is slidably connected to the outer wall of the vertical guide rod 23, so that the horizontal platform 26 can slide up and down stably. A serrated groove is provided on the outer wall of the serrated member 27, and a protruding long strip is provided on the top of the serrated member 27, so that the horizontal platform 26 can contact the long strip at the top of the serrated member 27 when moving upward. The outer wall of the limiting member 212 is provided with a protruding block, and the protruding block of the limiting member 212 is clamped with the serrated groove of the outer wall of the serrated member 27, so that the protruding block of the limiting member 212 forms a downward pressure on the serrated member 27. The outer wall of the direction rod 213 is slidably connected to the middle plate 210, and the outer wall of the direction rod 213 is slidably connected to the bottom fixed plate 28.

By rotating the threaded rod 29, the distance between the middle plate 210 and the stopper 212 can be adjusted, thereby compressing or relaxing the spring 211, and further adjusting the pressing force applied by the stopper 212 to the sawtooth 27.

Turn on the drive motor 37 to drive the hollow square rod 38, the square guide rod 310, the cylindrical rod 311 and the spiral member 312 to rotate, and the square guide rod 310 drives the cam member 317 to rotate. When the raised part of the cam member 317 rotates to contact the arc-shaped trigger member 316, the arc-shaped trigger member 316 drives the lower clamping plate 21 and the port of the flat wiring harness 5 to move toward the direction of the detection plug 47 for plugging, and detects the electrical variable of the flat wiring harness 5. When the raised part of the cam member 317 no longer contacts the arc-shaped trigger member 316, the spring five 314 drives the sliding member 315 and the arc-shaped trigger member 316 to move away from the detection plug 47, and the arc-shaped trigger member 316 drives the lower clamping plate 21 and the port of the flat wiring harness 5 to move away from the detection plug 47, so that the port of the flat wiring harness 5 is pulled out, and the plugging is repeated in this way.

[0045] The switching mechanism 4 includes a guide groove 41, which is opened at the top of the base plate 1. A receiving plate 42 is arranged at the top of the guide groove 41. The receiving plate 42 can slide smoothly when inserted into the guide groove 41. The outer wall of the receiving plate 42 is fixedly connected with a toothed condition 43. The top of the base plate 1 is fixedly connected with a positioning member 44. The inner wall of the positioning member 44 is slidably connected with a ratchet bar 45. The outer wall of the ratchet bar 45 is fixedly connected with one end of a connecting rod 46. The other end of the connecting rod 46 is rotatably connected to the cylindrical rod 311. The top of the receiving plate 42 is fixedly connected to There is a detection plug 47, which is fixed to the receiving plate 42 by bolts, so that different detection plugs 47 are installed on the top of the receiving plate 42. The top of the detection plug 47 is fixedly connected with a guide column 48, the top of the detection plug 47 is fixedly connected with one end of a spring 6 49, and the other end of the spring 6 49 is fixedly connected with a trapezoidal block 410, the top of the base plate 1 is fixedly connected with a vertical fixing rod 411, the outer wall of the vertical fixing rod 411 is fixedly connected with one end of a spring 7 412, and the other end of the spring 7 412 is fixedly connected with a fixed The positioning block 413 has a sliding guide rod 414 fixedly connected to its outer wall. The outer wall of the sliding guide rod 414 is slidably connected to the inner wall of the vertical fixed rod 411. The outer wall of the trapezoidal block 410 is slidably connected to the inner wall of the guide column 48, so that the trapezoidal block 410 can stably slide up and down on the inner wall of the guide column 48. The side of the positioning block 413 away from the vertical fixed rod 411 is conical. The conical part of the positioning block 413 resists and positions the gear condition 43, so that the gear condition 43 can maintain a limited position stability without the action of external force. Thereby, the receiving plate 42 fixed to the gear condition 43 maintains limited position stability. The outer wall of the ratchet bar 45 is provided with ratchet teeth. Since the ratchet bar 45 is located at the top of the trapezoidal block 410, when the ratchet bar 45 moves in the direction away from the connecting rod 46, the ratchet teeth of the ratchet bar 45 contact the trapezoidal block 410 in the forward direction, so that the trapezoidal block 410 compresses the spring six 49 and moves downward. When the ratchet bar 45 moves in the direction close to the connecting rod 46, the ratchet teeth of the ratchet bar 45 contact the trapezoidal block 410 in the reverse direction. At this time, the trapezoidal block 410 is driven by the ratchet teeth of the ratchet bar 45.There is a bottom spherical rod 33 between the blades of the spiral member 312. When the spiral member 312 rotates, it contacts the bottom spherical rod 33, so that the spiral member 312 moves in the direction of the drive motor 37. The spiral member 312 drives the cylindrical rod 311 and the square guide rod 310 to squeeze the spring 439. The cylindrical rod 311 drives the connecting rod 46 and the ratchet bar 45. At this time, the ratchet bar 45 will not drive the trapezoidal block 410 to move. The square guide rod 310 drives the cam member 317 to rotate and move in the direction of the drive motor 37 until the cam member 317 rotates and no longer contacts the arc-shaped trigger member 316. At this time, the cam member 317 rotates to contact the trigger block 36 to move upward, and the trigger block 36 drives the passage 317 to rotate. The rod 35 and the bottom spherical rod 33 move upward. At this time, the bottom spherical rod 33 no longer conflicts with the spiral member 312, so that the spring four 39 is released to drive the cylindrical rod 311 and the square guide rod 310 to move back in the direction away from the drive motor 37. At the same time, the cylindrical rod 311 drives the connecting rod 46 and the ratchet bar 45. At this time, the ratchet bar 45 will drive the trapezoidal block 410 to move, and the trapezoidal block 410 drives the guide column 48 and the detection plug 47 to move. The next detection plug 47 is replaced to face the port of the flat wiring harness 5, so that the device can automatically replace the detection plug 47. By replacing different detection plugs 47, special tests can be performed on specific electrical variables or connectors.

[0046] In summary, when the connectivity detection device of the connector and the flat harness is used to measure the electrical variable of the flat harness 5, the horizontal platform 26 is first lifted and moved upward, so that the horizontal platform 26 squeezes the spring 1 25, and the horizontal platform 26 drives the bottom fixing plate 28, the direction rod 213 and the limiter 212 to move upward. Under the action of the spring 211, the raised part of the limiter 212 contacts the groove of the sawtooth 27, and an upward force is applied to the sawtooth 27, so that the sawtooth 27 drives the upper clamping plate 22 to move upward. At this time, the port of the flat harness 5 is placed on the lower clamping plate 21, so that the cylindrical through hole of the flat harness 5 is plugged into the positioning column of the lower clamping plate 21 to ensure the limit. Then the horizontal platform 26 is released, and the spring 1 25 is released to drive the horizontal platform 26 to move downward, thereby driving the bottom fixing plate 28, the direction rod 213 and the limiter 212 to move downward. Under the action of the second spring 211, the raised part of the stopper 212 contacts the groove of the sawtooth 27, exerting a downward force on the sawtooth 27, so that the sawtooth 27 drives the upper clamp 22 to press the port of the flat harness 5 downward. When the applied pressing force reaches a certain level, that is, when the upper clamp 22 conflicts with the port of the flat harness 5, the stopper 212 will be subjected to a greater reverse force, thereby compressing the second spring 211. At this time, the stopper 212 moves relative to the groove of the sawtooth 27 until the force borne by the sawtooth 27 reaches a suitable range. By rotating the threaded rod 29, the distance between the intermediate plate 210 and the stopper 212 can be adjusted, thereby achieving compression or relaxation of the second spring 211, and further adjusting the pressing force applied by the stopper 212 to the sawtooth 27 to avoid damage to the port of the flat harness 5 due to excessive pressure. Protecting the integrity of the test equipment can ensure that the test conditions are consistent each time and reduce fluctuations in test results caused by equipment damage.

[0047] Then, the driving motor 37 is turned on to drive the hollow square rod 38, the square guide rod 310, the cylindrical rod 311 and the spiral member 312 to rotate, and the square guide rod 310 drives the cam member 317 to rotate. When the raised portion of the cam member 317 rotates to contact the arc-shaped trigger member 316, the arc-shaped trigger member 316 drives the lower clamping plate 21 and the port of the flat wiring harness 5 to move and plug in the direction of the detection plug 47 to detect the electrical variable of the flat wiring harness 5. When the raised portion of the cam member 317 no longer contacts the arc-shaped trigger member 316, the spring 5 314 drives the sliding member 315 and the arc-shaped trigger member 316 to move and plug in the lower clamping plate 21 and the port of the flat wiring harness 5 to move and plug in the direction of the detection plug 47 to detect the electrical variable of the flat wiring harness 5. Part 316 moves in the direction away from the detection plug 47, and the arc-shaped trigger part 316 drives the lower clamping plate 21 and the port of the flat wiring harness 5 to move in the direction away from the detection plug 47, so that the port of the flat wiring harness 5 is unplugged, and the plugging and unplugging are performed reciprocatingly, which plays a role of automatic repeated plugging and plugging. The mechanized plugging and unplugging actions eliminate the errors of human operation and ensure that the force, angle and speed of each plugging are consistent, thereby improving the reliability and repeatability of the test results, reducing the risk of damage caused by improper operation, and avoiding inaccurate tests due to fatigue or inattention.

[0048] There is a bottom spherical rod 33 between the blades of the spiral member 312. When the spiral member 312 rotates, it contacts the bottom spherical rod 33, so that the spiral member 312 moves in the direction of the drive motor 37. The spiral member 312 drives the cylindrical rod 311 and the square guide rod 310 to squeeze the spring 439. The cylindrical rod 311 drives the connecting rod 46 and the ratchet bar 45. At this time, the ratchet bar 45 will not drive the trapezoidal block 410 to move. The square guide rod 310 drives the cam member 317 to rotate and move in the direction of the drive motor 37 until the cam member 317 rotates and no longer contacts the arc-shaped trigger member 316. At this time, the cam member 317 rotates to contact the trigger block 36 to move upward, and the trigger block 36 drives the rod 35 and the bottom spherical rod 33 to rotate. The bottom spherical rod 33 moves upward, and the bottom spherical rod 33 no longer interferes with the spiral member 312, so that the spring 439 is released to drive the cylindrical rod 311 and the square guide rod 310 to move back to the direction away from the drive motor 37. At the same time, the cylindrical rod 311 drives the connecting rod 46 and the ratchet bar 45. At this time, the ratchet bar 45 drives the trapezoidal block 410 to move, and the trapezoidal block 410 drives the guide column 48 and the detection plug 47 to move. The next detection plug 47 is replaced and faces the port of the flat harness 5, so that the device can automatically replace the detection plug 47. By replacing different detection plugs 47, special tests can be performed on specific electrical variables or connectors, which increases the scope of application of the device. Quickly replacing the detection plug 47 reduces the equipment adjustment time when testing different types of flat harnesses 5, and improves the test efficiency.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
