Embodiment Construction

[0021] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the two-in-one differential mode inductor of this embodiment includes a ring magnetic core 3, a coil winding 1 and a coil winding 2 2 are wound at intervals on the ring magnetic core 3, and a ring is connected to the circumferential end surface of one end of the ring magnetic core 3. The oxygen baffle 5, the epoxy baffle 5 separates the coil winding one 1 and the coil winding two 2 along the radial direction of the annular magnetic core 3, and the circumferential end surface of the other end of the annular magnetic core 3 is fixedly connected to the base 4, and the base 4 is inserted There is inductor pin 6.

[0023] The coil winding one 1 and the coil winding two 2 are arranged symmetrically, and the epoxy baffle 5 is perpendicular to the circumferential end surface of the ring magnetic core 3 . ...

Abstract

The invention relates to a two-in-one differential mode inductor. An annular magnetic core is included. A coil winding 1 and a coil winding 2 are wound on the annular magnetic core at intervals, an epoxy baffle plate is connected to a circumferential end surface of one end of the annular magnetic core, the coil winding 1 and the coil winding 2 are separated by the epoxy baffle plate along a radialdirection of the annular magnetic core, a pedestal is fixedly connected to the circumferential end surface of the other end of the annular magnetic core, and inductance pin is inserted into the pedestal. The structure is compact and reasonable, in order to ensure that a 1.5 mm safe distance exists between a height of the coil winding and a middle portion of a shell, the height is controlled through an FR4 epoxy baffle plate, the two windings are effectively isolated and do not interfere with each other, an isolation plate does not need to be used, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of differential mode inductors, in particular to a two-in-one differential mode inductor. Background technique [0002] In the prior art, two differential-mode inductors are used on circuit boards used in induction cookers and other equipment, and each differential-mode inductor includes a magnetic core wound with a coil. The cost of production and assembly is high, and the product is bulky and expensive. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned existing production technology, the applicant provides a two-in-one differential mode inductor with a reasonable structure, compact structure, small height, small volume, reliable safety performance, low cost, and can be adapted to various application occasions. [0004] The technical scheme adopted in the present invention is as follows: [0005] A two-in-one differential mode inductor, comprising a ring magnetic core, ...
