Problems solved by technology

[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

A common mode inductor structurally comprises a closing cover, heat dissipation holes, a base and an operation box, the base is arranged at the bottom of the operation box, the base is fixedly connected with the operation box, the heat dissipation holes are formed in the operation box, the heat dissipation holes and the operation box are of an integrated structure, the closing cover is arranged at the top of the operation box, and the closing cover is in clearance fit with the operation box. When a coil needs to be adjusted, the fitting end of a winding wire and the edge of a magnetic ring is the adjusting shaft, and an adjusting shaft moves along an adjusting groove under the driving force generated when the coil is adjusted, so that the structure of the fitting end slides along the driving direction of the coil when the coil is adjusted, and the friction between the coil and the fitting edge is reduced when the coil is adjusted; and in addition, the contact end of the adjusting shaft is of an arc structure, so that friction damage of the coil caused by a sharp edge when the coil is adjusted is prevented.

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 [...
