Detailed Implementation

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Figures 1-5In one embodiment of this utility model, a vibration-resistant wire harness assembly includes an interface end 1 and a base 2 for mounting the interface end 1. A mounting seat 3 is provided above the base 2, and a vibration-damping protection mechanism 4 is provided between the base 2 and the mounting seat 3. A positioning mechanism 5 for fixing the interface end 1 is provided inside the mounting seat 3. The vibration-damping protection mechanism 4 includes two sets of cross-distributed brackets 401, with sliders 402 rotatably mounted below each set of brackets 401. The sliders 402 are slidably connected to the base 2. A first sliding rod 403 is fixedly installed inside the base 2, and the sliders 402 are slidably sleeved with the first sliding rod 403. A damper 405 is fixedly installed between the slider 402 and the base 2, and a third spring 406 is fitted onto the damper 405. The positioning mechanism 5 includes three sets of annularly distributed adjusting brackets 502 within the mounting seat 3. The mounting seat 3 is provided with three sets of guide rails 501 corresponding to the adjusting brackets 502. The three sets of adjusting brackets 502 are respectively positioned with... The corresponding guide rail 501 is slidably connected, and each of the three sets of adjustment brackets 502 is fixedly installed with a locking rod 503. Three sets of annularly distributed slots 504 are opened on the outer wall of the interface end 1. The three sets of locking rods 503 are set in correspondence with the slots 504. The three sets of locking rods 503 are movably engaged with the corresponding interface end 1 through the slots 504. The mounting base 3 is equipped with a drive wheel 508. The drive wheel 508 is rotatably connected to the mounting base 3 through the handle 509. The anti-vibration protection mechanism 4 composed of cross bracket 401 and damping spring effectively absorbs vibration energy and prevents the interface end 1 from loosening in a vibration environment. The three sets of adjustable locking rods 503, together with the drive wheel 508, realize the quick positioning and stable engagement of different models of interface end 1. The locking mechanism of two sets of ratchet 512 and pawl 513 ensures that the handle 509 will not rotate accidentally after installation, avoiding the failure of the interface end 1. The overall design significantly improves the connection reliability and durability of the wire harness in a high vibration environment.

[0027] In this embodiment, reference Figure 2 , Figure 3 As shown, two sets of symmetrically distributed first springs 404 are sleeved on the first slide rod 403. The two ends of the two sets of first springs 404 are fixedly connected to the slider 402 and the base 2, respectively. The vibration-damping disconnection harness assembly achieves stable connection through a double-layer protection mechanism. The vibration protection mechanism 4 adopts a combination structure of cross brackets 401 and dampers 405. When external vibration is transmitted to the base 2, the two sets of brackets 401 will slide along the first slide rod 403 with the slider 402. The vibration impact is absorbed by the elastic deformation of the third spring 406 and the energy dissipation of the damper 405. At the same time, the first spring 404 provides a restoring force, so that the mounting base 3 always remains in a stable position, effectively isolating the influence of vibration on the interface end 1.

[0028] In this embodiment, reference Figure 4 and Figure 5As shown, an adjusting disc 505 is rotatably mounted inside the mounting base 3. The adjusting disc 505 is rotatably connected to the mounting base 3 via a rotating frame 506. Three sets of annularly distributed guide grooves 510 are provided on the adjusting disc 505. Guide rods 511 are fixedly mounted on each of the three sets of adjusting frames 502. The guide rods 511 are correspondingly arranged with the guide grooves 510 and are slidably connected to the adjusting disc 505 via the guide grooves 510. A toothed ring 507 is sleeved on the rotating frame 506, and a drive wheel 508 meshes with the toothed ring 507. Two sets of symmetrically distributed ratchet wheels 512 are sleeved on the handle 509. The mounting base 3 has two sets of pawls 513 corresponding to the ratchet wheels 512. The pawls 513 are connected to the corresponding... The ratchet 512 engages with the pawl 513, which is rotatably connected to the mounting base 3 via a rotating rod 514. Gears 516 are sleeved on both rotating rods 514. Two sets of racks 517, corresponding to the gears 516, are slidably installed inside the mounting base 3, engaging with their respective gears 516. Torsion springs 515 are sleeved on the rotating rods 514, with both ends of the torsion springs 515 fixedly connected to the pawl 513 and the mounting base 3. A connecting frame 518 is slidably installed inside the mounting base 3, fixedly connected to both sets of racks 517. Two sets of second sliding rods 519 are fixedly installed inside the mounting base 3, and the connecting frame 518 slides against the two sets of second sliding rods 519. Next, two sets of symmetrically distributed second springs 520 are sleeved on each of the two sets of second slide rods 519. The two ends of the two sets of second springs 520 are fixedly connected to the connecting frame 518 and the mounting base 3, respectively. The positioning mechanism 5 drives the gear ring 507 and the adjusting plate 505 to rotate through the rotation drive wheel 508. The guide groove 510 and the guide rod 511 cooperate to make the three sets of adjusting frames 502 move radially synchronously, driving the locking rod 503 to insert into the locking groove 504 of the interface end 1 to achieve precise locking. The two sets of ratchet 512 and pawl 513 mechanisms achieve bidirectional locking of the handle 509 through the linkage of gear 516 and rack 517. When the handle 509 is rotated to the position, the pawl 513 is engaged by the torsion spring 5 Under the action of 15, the handle 509 engages between the teeth of ratchet 512. At the same time, rack 517 pushes gear 516 to lock rotating rod 514, forming a double anti-reverse protection to ensure that interface end 1 will not loosen due to accidental rotation of handle 509 in a vibration environment. When it is necessary to rotate handle 509, the two sets of racks 517 slide synchronously by pulling connecting bracket 518. In conjunction with gear 516, the two sets of rotating rods 514 rotate, thereby causing the two sets of pawls 513 to deviate from the corresponding ratchet 512, releasing the restriction of the two sets of ratchet 512 and pawls 513 on handle 509. The rotation of handle 509 can drive drive wheel 508 to rotate synchronously, completing the adjustment of the distance between the three sets of locking rods 503.

[0029] In this embodiment, the vibration-damping disconnect harness assembly achieves stable connection through a double-layer protection mechanism. The vibration protection mechanism 4 adopts a combination structure of cross brackets 401 and dampers 405. When external vibration is transmitted to the base 2, the two sets of brackets 401 slide along the first slide rod 403 with the slider 402. The vibration impact is absorbed by the elastic deformation of the third spring 406 and the energy dissipation of the damper 405. At the same time, the first spring 404 provides a restoring force, so that the mounting base 3 always remains in a stable position, effectively isolating the impact of vibration on the interface end 1. The positioning mechanism 5 drives the gear ring 507 and the adjusting plate 505 to rotate through the rotation drive wheel 508. The cooperation of the guide groove 510 and the guide rod 511 causes the three sets of adjusting brackets 502 to move radially synchronously, driving the locking rod 503 to insert into the locking groove 504 of the interface end 1 to achieve precise locking. The two sets of ratchet 51 The pawl 513 mechanism achieves bidirectional locking of the handle 509 through the linkage of gear 516 and rack 517. When the handle 509 is rotated to the position, the pawl 513 is engaged between the teeth of the ratchet 512 under the action of the torsion spring 515. At the same time, the rack 517 pushes the gear 516 to lock the rotating rod 514, forming a double anti-reverse protection to ensure that the interface end 1 will not loosen due to accidental rotation of the handle 509 in a vibration environment. When it is necessary to rotate the handle 509, the two sets of racks 517 are moved synchronously by pulling the connecting bracket 518. In conjunction with the gear 516, the two sets of rotating rods 514 are rotated, which causes the two sets of pawls 513 to deviate from the corresponding ratchet 512, releasing the restriction of the two sets of ratchet 512 and pawls 513 on the handle 509. The rotation of the handle 509 can drive the drive wheel 508 to rotate synchronously, completing the adjustment of the distance between the three sets of locking rods 503.
