[0003] The winding bobbin of the common mode inductor is a magnetic ring structure. Due to the small aperture of the magnetic ring, it is difficult to control when winding the coil, which will cause the winding to deviate. At this time, the coil has already been deformed to fit the magnetic ring due to winding. The offset coil can only be adjusted by sliding the winding. When the coil is adjusted, it will rub against the edge of the magnetic ring and cause the coil to be damaged.

Abstract
The invention discloses a common mode inductor, the structure of which comprises a closed cover, a cooling hole, a base, and an operation box. The bottom of the operation box is provided with a base, and the base is fixedly connected with the operation box. The hole and the operation box are an integrated structure, and the top of the operation box is provided with a closing cover, which is matched with the operation box. When the coil of the present invention needs to be adjusted, because the bonding end of the winding wire and the edge of the magnetic ring is an adjustment shaft, adjust The shaft is driven by the coil adjustment and moves along the adjustment groove, so that when the coil is adjusted, the structure of the fitting end slides along with the driving direction of the coil, so as to reduce the friction between the coil and the fitting edge during adjustment. In addition, the contact end of the adjustment shaft has a circular arc structure, which prevents the coil from being damaged by friction due to sharp edges during coil adjustment.
Description
technical field [0001] The invention relates to the field of inductance, in particular to a common mode inductor. Background technique [0002] Common-mode inductors, also known as common-mode choke coils, are often used to filter common-mode electromagnetic interference signals in computer switching power supplies. In board design, common-mode inductors also function as EMI filters to suppress high-speed signal lines. The electromagnetic wave is radiated outward; [0003] The winding bobbin of the common mode inductor is a magnetic ring structure. Due to the small aperture of the magnetic ring, it is difficult to control when winding the coil, which will cause the winding to deviate. At this time, the coil has already been deformed to fit the magnetic ring due to winding. The offset coil can only be adjusted by sliding the winding. When the coil is adjusted, it will rub against the edge of the magnetic ring and cause the coil to be damaged. Contents of the invention [...
