Abstract
Description
Technical Field
[0001] This utility model relates to the field of engine wiring harness calibration technology, and in particular to an engine wiring harness calibration tool. Background Technology
[0002] An engine wiring harness calibration tool is a device specifically designed to check the correctness and integrity of engine wiring harness connections. It typically features high precision and efficiency, ensuring the reliability and safety of engine wiring harnesses in complex environments. Through simple hardware circuitry and a reasonable structural design, when the test probe touches a pin of any branch connector of the wiring harness, the device can directly display the pin numbers of all ECUs connected to it inside the wiring harness.
[0003] Ensure the calibration tool is in good condition with no damage or missing parts. Connect one end of the test lead to the test lead connector on the calibration device, and the other end to the test pen. Connect one end of the engine wiring harness to the ECU connector on the harness end, and the other end to each branch connector of the wiring harness. Set the corresponding test parameters on the calibration device according to the type and specification of the engine wiring harness to be tested. Connect the ECU connector on the harness end to the ECU connector on the calibration device. Turn on the power switch of the calibration device to start the test program. Use the test pen to touch the pins of each branch connector of the wiring harness one by one, observe the test results displayed on the calibration device, and determine whether the internal connection of the wiring harness is correct.
[0004] However, existing tools do not take into account the stability of the connector during the calibration process after insertion. They lack specialized clamping devices or have unreasonable clamping device designs, which makes the connector easy to fall off due to accidental contact or slight vibration. Furthermore, different engine wiring harnesses and connector specifications vary, and existing tools may lack sufficient adaptability to provide suitable clamping for connectors of various sizes, resulting in loose clamping or damage to the connector, thereby affecting the accuracy of calibration and the safety of the connector.

[0014] The beneficial effects of this utility model are:
[0015] 1. Driven by the motor, the rotating plate rotates, which in turn pulls the clamping block along the preset moving groove through the connecting plate. This achieves adaptive clamping and fixing of connectors of different sizes, avoiding the cumbersome process of changing the clamping structure due to differences in connector size in traditional methods. At the same time, it significantly enhances the stability of the connector, ensuring that the connector will not fall off even in the event of accidental contact or slight vibration.

[0024] Example 1
[0025] Reference Figure 1-3 This is the first embodiment of the present invention, which provides an engine wiring harness inspection tool, including a body 1. The top of the body 1 is fixedly connected to a plurality of evenly distributed interfaces 3. The outer wall of the interfaces 3 is fixedly connected to a mounting block 4. The inner wall of the mounting block 4 is slidably connected to four clamping blocks 5 arranged in a circular array. The clamping blocks 5 are used to clamp the connectors. The inner wall of the body 1 is slidably connected to a rotating rod 6. The outer wall of the rotating rod 6 is equipped with a pushing rod 12, which is used to push a push plate 15. The top of the body 1 is slidably connected to a plurality of moving blocks 20 arranged in a linear array. The top of the moving blocks 20 is equipped with a clamp 22. The clamp 22 is made of soft material to facilitate the insertion and fixing of the wiring harness.
[0026] A drive motor is fixedly installed at the bottom of the rotating rod 6. An installation groove is provided on the inner wall of the body 1 to facilitate the installation of the drive motor. A rotating plate 11 is fixedly connected to the top of the rotating rod 6. Four fixed columns 18 arranged in a circular array are fixedly connected to the bottom of the rotating plate 11.
[0027] A connecting plate 13 is slidably connected to the outer wall of the fixed column 18. The cross-section of the connecting plate 13 is "L" shaped. A mounting column 14 is slidably connected to the outer wall of the connecting plate 13. A rectangular plate 8 is fixedly connected to the top of the mounting column 14. The rectangular plate 8 is used to drive the connecting rod 7 to move. The top of the rectangular plate 8 is fixedly connected to the connecting rod 7, which is fixedly connected to the bottom of the clamping block 5. The connecting rod 7 is used to drive the clamping block 5 to move.
[0028] Two rectangular plates 8 are fixedly connected to the bottom of a connecting column 9, and a movable column 10 is fixedly connected to the outer wall of the connecting column 9. A display screen 2 is fixedly installed on the top of the body 1, and a movable groove is provided on the inner wall of the mounting block 4 to facilitate the sliding of the connecting rod 7.
[0029] During use, insert the connector of the wire harness into the interface, start the drive motor to drive the rotating plate 11 to rotate via the rotating rod 6, the rotating plate 11 drives the connecting plate 13 to rotate via the fixed column 18, the connecting plate 13 drives the rectangular plate 8 to move via the mounting column 14, the rectangular plate 8 drives the clamping block 5 to move along the moving groove via the connecting rod 7, and at the same time the rectangular plate 8 drives the movable column 10 to move and retract via the connecting column 9. After the calibration is completed, start the drive motor to drive the rotating plate 11 to move via the rotating plate 11, and the rotating plate 11 drives the clamping block 5 to reset via the connecting rod 7.
[0030] Example 2
[0031] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the outer wall of the rotating rod 6 is fixedly connected to a disc 17 which is fixedly connected to the outer wall of the push rod 12. The disc 17 is used to drive the push rod 12 to rotate. The top of the machine body 1 is provided with a sliding groove to facilitate the sliding of the moving block 20. The inner wall of the sliding groove is slidably connected to a push plate 15, which is used to press the moving block 20 to limit its position.
[0032] The inner wall of the sliding groove is provided with an arc-shaped groove 19 to facilitate the sliding connection of the push rod 12. Multiple linearly distributed springs 16 are connected between the inner wall of the moving groove and the outer wall of the push plate 15. The springs 16 are used to push the push plate 15. The inner wall of the moving block 20 is connected with a sliding column 21 that is fixedly connected to the bottom end of the chuck 22. The sliding column 21 is used to drive the chuck 22 to rotate.
[0033] During use, after inserting the wire harness connector into interface 3, rotate the sliding column 21 to facilitate wire harness insertion, pushing the outer wall of the wire harness into the inner wall of the clamp 22. Since the clamp 22 is made of soft material, the wire harness enters the inner wall of the clamp 22, pushing the moving block 20 to adjust the position of the wire harness. The drive motor drives the clamping block 5 to clamp the connector through the rotating rod 6. At the same time, the rotating rod 6 drives the push rod 12 to rotate through the disc 17. The rotating push rod 12 squeezes the push plate 15, and the push plate 15 is forced to squeeze the spring 16. At the same time, the push plate 15 squeezes the moving block 20 to fix its position. When disassembly is required, the drive motor drives the push rod 12 to disengage from the outer wall of the push plate 15. The spring 16 is released and pushes the push plate 15 to stop squeezing the moving block 20, thus removing the wire harness from the inner wall of the clamp 22. The operation is now complete.
[0034] The remaining structure is the same as that in Example 1.
[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
