[0026] During the use of the vehicle-mounted common-mode filtering inductor, the push plate 302 is pushed to slide outward on the slide groove 301 through the transmission component. During the outward sliding of the push plate 302, the push plate 302 is abutted against the inner side of the coil 102 to support the coil 102. By supporting the coil 102, the coil 102 maintains a certain tension during use, reducing the probability of the coil 102 being loosely wound due to looseness or deformation, avoiding magnetic flux leakage, and facilitating the stable use of the vehicle-mounted common-mode filtering inductor.

[0027] There are multiple groups of protection components, and the multiple groups of protection components are arranged in a ring array on the mounting rod 2; the support protection effect is guaranteed by the multiple groups of protection components arranged in a ring array.

[0028] The slide groove 301 and the push plate 302 match each other, and both the slide groove 301 and the push plate 302 are arranged in a rectangular shape; the movement of the push plate 302 after being subjected to force is guided by the slide groove 301 and the push plate 302 that are arranged in a rectangular shape and match each other.

[0029] The transmission assembly includes an installation cavity 401 opened on the installation rod 2, and two groups of transmission rings 402 are arranged inside the installation cavity 401. A connecting rod 403 is arranged between the transmission ring 402 and the push plate 302. The two ends of the connecting rod 403 are rotatably connected with the transmission ring 402 and the push plate 302 respectively through a pin shaft. A driving assembly for driving the two groups of transmission rings 402 is arranged on the installation rod 2; through the driving assembly, the two groups of transmission rings 402 are driven to move away from each other under force. In the process of the two groups of transmission rings 402 moving away from each other, the push plate 302 is pushed to slide outward on the slide groove 301 through the two groups of connecting rods 403.

[0030] The driving assembly includes a double-headed screw 501 rotatably connected to the mounting rod 2, and two sets of transmission rings 402 are respectively arranged to mesh with the two ends of the double-headed screw 501, and one end of the double-headed screw 501 is located on the outside of the mounting rod 2 and is fixed with a driving pin 502; the double-headed screw 501 is driven to move by the driving pin 502, and because the threads at the two ends of the double-headed screw 501 are arranged in opposite directions, during the rotation of the double-headed screw 501, the two sets of transmission rings 402 are respectively meshed with the two ends of the double-headed screw 501, and the two sets of transmission rings 402 are driven to move away from each other under force.

[0032] During the installation of the vehicle-mounted common-mode filter inductor, the coil 102 is sleeved on the outside of the mounting rod 2, and during the sleeve installation process, the two ends of the coil 102 are respectively against the two groups of pins 103;

[0033] During the use of the vehicle-mounted filtering common-mode inductor, in order to prevent the coil 102 from being loosened or deformed during use, resulting in loose winding, the double-headed screw 501 is driven to move through the driving pin 502. Since the threads at both ends of the double-headed screw 501 are arranged in opposite directions, during the rotation of the double-headed screw 501, the two sets of transmission rings 402 are respectively meshed with each other at the two ends of the double-headed screw 501 to drive the two sets of transmission rings 402 to move away from each other. During the movement away from each other, the push plate 302 is pushed to slide outward on the slide groove 301 by the two sets of connecting rods 403. During the sliding outward of the push plate 302, the push plate 302 is abutted against the inner side of the coil 102 to support the coil 102. The supporting effect on the coil 102 keeps a certain tension of the coil 102 during use, reduces the probability of the coil 102 being loosely wound or deformed, avoids magnetic flux leakage, and facilitates the stable use of the vehicle-mounted common-mode filter inductor.
