[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a locking mechanism for a wire harness connector, including a fixed connecting end 1, a movable connecting end 2 on the right side of the fixed connecting end 1, a connecting block 3 fixedly installed on the top surface of the fixed connecting end 1, two connecting boxes 9 with the front and rear sides of the connecting block 3, and a pull rod 15 extending outward to the outside of the connecting box 9. The connecting block 3 above the fixed connecting end 1 serves to connect the movable connecting end 2, preventing the fixed connecting end 1 and the movable connecting end 2 from falling off due to vibration during use, thus affecting the stability of the connection. The two connecting boxes 9 above the movable connecting end 2 serve to fix the connecting block 3 during use. A support block 4 is installed on the outside of the connecting block 3, a support spring 6 is fixedly connected to the right side of the support block 4, and a limit plate 7 is fixedly connected to the right end of the support spring 6. The front and rear sides of the connecting block 3 have slots 5, and the inner side of the slot 14 and the horizontal cross-section of the slot 5 are at an angle... The right-angled triangle, using the support block 4 and support spring 6, along with the limiting plate 7, restricts the position of the limiting plate 7. It supports the limiting plate 7 at the left side of the contact plate 8, restricting the position of the movable plate 11 and preventing it from loosening. This ensures the two plates 8 remain in contact, thus limiting the position of the connecting block 3. The locking block 14 is movably fitted into the inner cavity of the slot 5. Two connecting boxes 9 are fixedly installed on the top surface of the movable connecting end 2. A fixing spring 13 is fixedly installed inside the connecting box 9. A locking block 14 is fixedly connected to the inner side of the spring 13, and a pull rod 15 is fixedly connected to the outer side of the locking block 14. The locking block 14 is supported by the fixed spring 13. At the same time, locking blocks 14 are respectively set at the front and rear of the connecting block 3. This can prevent the locking block 14 from moving outward due to vibration during use, thus preventing the fixed spring 13 from being compressed. The two locking blocks 14 can effectively improve the locking safety and prevent the loosening of a single locking block 14. At the same time, the fixed spring 13 can quickly push the locking block 14 into the state of locking and locking groove 5 after the external force ends.

[0022] Please see Figures 3 to 5Support shafts 10 are fixedly installed on the inner sides of the two connecting boxes 9. Movable plates 11 are movably fitted onto the outer sides of the support shafts 10. The top surface of the limiting plate 7 and the top surface of the left side of the movable plate 11 are fitted together. The clamping plate 8 is a right-angled triangular prism. The two clamping plates 8 improve the connection stability between the connecting block 3 and the connecting box 9 during use. Simultaneously, the support spring 6 and the two fixed springs 13 ensure that one side of the three outer sides of the connecting block 3 remains stably connected when the vehicle body is subjected to vibration. The bottom surface of the movable plate 11 and the top surface of the connecting block 3 are fixedly connected with clamping plates 8. Flipping the movable plate 11 allows... The movable plate 11 rotates around the axis of the support shaft 10, causing the locking plate 8 on the bottom surface of the movable plate 11 to lock onto the top locking plate 8 of the connecting block 3. The movable plate 11 is supported by the limiting plate 7, which facilitates the use of the device. The two locking plates 8 are set to stably connect the connecting block 3 and the connecting box 9 during use. The top of the limiting plate 7 is inclined, and the height value on the left side of the top surface of the limiting plate 7 is greater than the height value on the right side. The top surface of the limiting plate 7 is set to be inclined so that when the movable plate 11 rotates around the support shaft 10 under the action of gravity during use, it is convenient to push the limiting plate 7 forward, so that the two locking plates 8 can be quickly reset after separation.

[0023] In summary, the locking mechanism of this wire harness connector, during use, involves rotating the movable plate 11 around the axis of the support shaft 10, causing the movable plate 11 to flip to a position perpendicular to the top surface of the connecting box 9. Then, the movable connecting end 2 is installed from the right side of the fixed connecting end 1 into the inner cavity of the fixed connecting end 1. Simultaneously, the movable connecting end 2 drives the two connecting boxes 9 above to move from the sides of the two connecting blocks 3 to the outside of the connecting blocks 3. During this movement, the connecting blocks 3 first push the locking block 14 outwards, utilizing the inclined surface on the left side of the locking block 14 to... The connecting block 3 pushes the locking block 14 to the inner cavity of the connecting box 9, causing the fixing spring 13 to be in a compressed state. Then, after the connecting box 9 has completely moved to the outside of the connecting block 3, the fixing spring 13 will push the locking block 14 to move inward, causing the locking block 14 to move into the inner cavity of the slot 5. At the same time, the movable plate 11 is flipped, causing the movable plate 11 to rotate around the axis of the support shaft 10, so that the locking plate 8 on the bottom surface of the movable plate 11 is locked above the locking plate 8 on the top surface of the connecting block 3. The limiting plate 7 is used to support the movable plate 11, which facilitates the use of the device.
