Description
Technical Field
[0001] This invention relates to the technical field of testing devices, and specifically to a testing device for mobile phone charging ports and charging cables. Background Technology
[0002] With the widespread adoption and continuous functional upgrades of smartphones, the power connector and its accompanying charging cable have become indispensable core accessories for mobile phones, and their reliability directly impacts user experience and product lifespan. During mobile phone manufacturing, the plug-in / plug-out durability and contact stability of the power connector, as well as the bending resistance of the charging cable, are key indicators for measuring product quality. Therefore, they require batch testing using specialized testing equipment to ensure that products leaving the factory meet quality standards.
[0003] Currently, existing testing methods for mobile phone charging ports and charging cables have many shortcomings: most testing devices can only perform single-direction insertion / removal tests or bending tests, and cannot simultaneously complete integrated tests of the reliability of the plug insertion / removal and the bending loss of the charging cable. The testing efficiency is low, and it is difficult to simulate the scenario in actual use where users simultaneously perform insertion / removal and bending, such as swinging or flipping the phone while holding it to charge, causing the charging cable to bear both insertion / removal stress and bending stress. The test results deviate significantly from actual usage conditions and cannot fully reflect the true reliability of the product. Summary of the Invention

[0024] Example 2 like Figure 1-5 As shown, the present invention provides a testing device for mobile phone plug and charging cable, including a workbench 1, a rotating mechanism 3 and a flipping and swinging mechanism 4. The workbench 1 is provided with a mounting frame 2, which includes a fixed base 21 and a mounting plate 22. Two fixed bases 21 are provided and symmetrically arranged on the workbench 1. The mounting plate 22 has an inverted "L" shaped structure and is connected to the top of both fixed bases 21.

A limiting component 44 for fixing the mobile phone plug of the charging cable includes a limiting seat 441 and a tightening screw 443. The limiting seat 441 is provided on a rotating shaft 411 and has a limiting groove 442 for placing the mobile phone plug of the charging cable.

However, the rotating mechanism 3 is mounted on the worktable 1 and drives the mobile phone fixed thereon to reciprocate. The rotating mechanism 3 includes a drive motor 34, a drive disk 31, and a limiting component 33. The drive motor 34 is mounted on the bottom of the worktable 1, the drive disk 31 is mounted on the output shaft of the drive motor 34, and a bracket 32 is provided on the side of the drive disk 31. The limiting component 33 is used to fix the mobile phone on the bracket 32 and rotate the mobile phone on the bracket 32. The limiting component 33 includes... The bracket 32 is equipped with a fixed clamping block 331, a movable clamping block 332, and a threaded rod 335. The fixed clamping block 331 is provided on the bracket 32. The movable clamping block 332 is opposite to the fixed clamping block 331 and is slidably connected to two slide rails 333 on the bracket 32. A pad 334 is provided between the two slide rails 333. The threaded rod 335 is threadedly connected to the side plate on the bracket 32 and its end is rotatably connected to the movable clamping block 332. The bracket 32 is equipped with a limiting frame 336 for limiting the mobile phone and clamping and fixing the mobile phone. This makes it easy to plug and unplug the charging cable into the same phone's charging port by having both the front and back of the plug face the same way.
[0025] Detailed implementation methods and principles: First, place the phone on the limiting component 33 of the rotating mechanism 3, rotate the threaded rod 335 to push the moving clamp 332 to slide along the two slide rails 333 on the bracket 32, and cooperate with the fixed clamp 331 to clamp the phone. The limiting frame 336 on the bracket 32 provides auxiliary limiting for the phone to prevent the phone from shifting during the test. Then, place the phone plug of the charging cable into the limiting groove 442 of the limiting component 44, and tighten the tightening screws 443 on both sides of the limiting seat 441 so that the tightening screws 443 abut against the phone plug to securely fix the phone plug; then place the power plug of the charging cable into the limiting groove 472 of the limiting component 47, and tighten the tightening screws 473 on both sides of the limiting seat 471 to fix the power plug.
[0026] Next, the charging cable is tested. Cylinder 43 is activated, and its piston rod extends and pushes the moving frame 41 to slide horizontally along the guide rod 42 on the front side of the mounting plate 22. When the moving frame 41 slides, it drives the rotating shaft 411 and the limiting component 44 to move forward synchronously. At this time, the insertion rod 451 on the drive plate 45 slides forward along the horizontal groove 461 of the drive groove 46 of the mounting plate 22. Since the horizontal groove 461 is a straight structure, the insertion rod 451 does not drive the rotating shaft 411 to rotate during the movement. The limiting component 44 remains horizontal, thereby driving the mobile phone plug of the charging cable to move horizontally forward and accurately insert into the fixed mobile phone plug, completing the plugging action of the charging cable. Then, cylinder 43 is activated, its piston rod extends, and pushes the moving frame 41 to slide horizontally forward along the guide rod 42 on the front side of the mounting plate 22. Simultaneously, the moving frame 41 drives the rotating shaft 411, the limiting component 44, and the charging cable / phone plug fixed thereon to move forward. At this time, the insertion rod 451 on the drive plate 45 slides forward along the horizontal groove 461 of the drive groove 46. Since the horizontal groove 461 is a straight structure, the insertion rod 451 does not drive the rotating shaft 411 to rotate during the sliding process. The limiting component 44 remains horizontal, thereby driving the charging cable / phone plug to move horizontally forward and accurately insert it into the phone's charging port, completing the charging cable insertion action. Then, the piston rod of cylinder 43 drives the limit component 44 and the charging cable phone plug to move in the opposite direction, so that the charging cable phone plug is disconnected from the phone plug. Then, the drive motor 34 at the bottom of the workbench 1 is started. The output shaft of the drive motor 34 drives the drive disk 31 to rotate, so that the phone fixed on the bracket 32 also reciprocates to the other side of the workbench 1. When the insertion rod 451 slides along the horizontal groove 461 to the entrance of the arc groove 462, the moving frame 41 continues to move under the continuous push of the cylinder 43. The insertion rod 451 enters the arc groove 462 and slides along the trajectory of the arc groove 462. The trajectory of the arc groove 462 drives the insertion rod 451 to reciprocate around the axis of the rotating shaft 411. The insertion rod 451 drives the rotating shaft 411 to reciprocate synchronously through the drive plate 45. The rotating shaft 411 then drives the limiting component 1 44 and the charging cable mobile phone plug to flip. During the process of the moving frame 41 sliding back and forth and the limiting component 1 44 reciprocating, the mobile phone plug of the charging cable moves synchronously with the limiting component 1 44. The power plug is fixed by the limiting component 2 47, so that the charging cable is reciprocated and stretched and bent between the limiting component 1 44 and the limiting component 2 47, so that the front and back of the mobile phone plug of the charging cable change, and is inserted and rotated into the mobile phone plug on the other side. After the preset number of tests is reached, the drive motor 34 stops working, and the drive disk 31, cylinder 43 and mobile phone are reset to their initial positions. Then, the first tightening screw 443, the second tightening screw 473 and the threaded rod 335 are loosened, the charging cable and mobile phone after testing are removed, and the reliability of the charging cable insertion and removal, bending loss and contact status of the mobile phone plug are checked to complete the entire test process.
