The fixing structure is movably connected with the magnetic ring 1, the fixing structure comprises two U-shaped clamping blocks 211 with the same structure, threaded holes are respectively formed in the opening end and the closing end of each U-shaped clamping block 211, the U-shaped clamping blocks 211 are transversely clamped on the magnetic ring 1, the top surface and the bottom surface of the magnetic ring 1 are respectively arranged in a plane 12, and the U-shaped clamping blocks 211 are clamped at the positions 12 on the plane.
Referring to fig. 1, 3 and 4, in the embodiment, the separating element 2 is detachably connected to the magnetic ring 1, and before the independent coil 3 is wound on the magnetic ring 1, the separating element 2 is not fixed on the magnetic ring 1, which is beneficial for winding the independent coil 3, and the independent coil 3 in fig. 1 is not shown. The winding of the independent coil 3 of the existing common mode inductor is inconvenient and is a common problem, the common mode inductor is generally wound by hands, and if the separation component 2 arranged on the magnetic ring 1 is fixed or the size of the separation component 2 is large, the hands can be prevented from winding the independent coil 3, so that the production efficiency is influenced. In addition, the separating component 2 arranged on the common mode inductor can not apply stress to the magnetic ring 1, otherwise, the inductance of the common mode inductor can be influenced, and the work of the common mode electric ring is further influenced. As shown in fig. 1 and fig. 2, in the present embodiment, after the independent coil 3 is completely wound, the two U-shaped blocks 211 of the fixing structure are clamped on the magnetic ring 1, and then the two screws 212 are screwed into the threaded holes of the U-shaped blocks 211, so that the two screws 212 connect the two U-shaped blocks 211. It should be noted that the screw and the fixing structure only play a role of separating the two independent coils 3, the two screws 212 do not need to press the two U-shaped blocks 211 tightly, and only the screws are connected with the two U-shaped blocks 211, so that the separating assembly 2 does not generate stress on the magnetic ring 1.
Further, as shown in fig. 4, in some scenarios, on the premise of not damaging the performance of the magnetic ring 1, the top surface and the bottom surface of the magnetic ring 1 may be set as the planar arrangement 12, and the U-shaped latch 211 is latched at the position of the planar arrangement 12, so that the U-shaped latch 211 may be prevented from sliding on the magnetic ring 1, and the stability of the U-shaped latch 211 on the magnetic ring 1 may be improved.
Example 2
The embodiment provides a common mode inductor capable of being assembled quickly, which comprises a magnetic ring 1, two independent coils 3 wound on the magnetic ring 1, a separation component 2 used for separating the two independent coils 3, and a coil winding unit, wherein the separation component 2 is arranged on the magnetic ring 1; the separation component 2 comprises two screws and fixing structures connected with two ends of each screw, threaded holes matched with the screws 222 are formed in the fixing structures, the fixing structures are arranged on the magnetic ring 1, one screw 222 is located on the left side of the magnetic ring 1, and the other screw 222 is located on the right side of the magnetic ring 1.
The fixing structure and the magnetic ring 1 are integrally formed, the fixing structure comprises four fixing blocks 221, the four fixing blocks 221 are arranged in a rectangular shape, the left side wall and the right side wall of the magnetic ring 1 are respectively provided with two fixing blocks 221, and each fixing block 221 is provided with a threaded hole.

If the stop block with the overlong length is arranged on the inner side wall of the magnetic ring 1, the independent coil 3 cannot be wound by hands conveniently, the stop block with the overlong length is arranged on the left side wall or the right side wall of the magnetic ring 1, the placement of the magnetic ring 1 cannot be facilitated, and the stop block is too short, so that the effect of separating the independent coil 3 is not obvious. Therefore, in the present embodiment, the small-sized fixing blocks 221 are respectively disposed on the left side surface and the right side surface of the magnetic ring 1, and then the two screws 222 are screwed into the threaded holes, the left screw 222 connects the two fixing blocks 221 on the left side, and the right screw 222 connects the two fixing blocks 221 on the right side, which serves as a function of separating the independent coils 3. Due to the screw 222, the fixing block 221 can be arranged small to separate the two independent coils 3. Moreover, the screw 222 and the fixing blocks 221 only have a threaded connection function, and the screw 222 does not extrude the two fixing blocks 221 toward the middle or push the two fixing blocks 221 toward the two sides, so that the separating assembly 2 in this embodiment does not generate stress on the magnetic ring 1, and does not affect the performance of the common mode inductor.
