SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving the too big problem that leads to magnetic core saturation and technology complicacy of the differential mode component that above-mentioned, provide a differential mode inductor is altogether to assembled.
The utility model discloses a realize through following technical scheme:
the utility model provides an assembled common mode inductor, its characterized in that, the inductor includes closed U type magnetic core, cubic magnetic core, T type magnetic core, flat coil and base, the flat coil coiling is in on the closed U type magnetic core, the base is connected to flat coil end of a thread one end, cubic magnetic core setting is in closed U type magnetic core one side, cubic magnetic core is connected to flat coil end of a thread one end, T type magnetic core setting is between two arms of closed U type magnetic core.
As a further supplement to the above solution, the flat coil includes a first coil and a second coil respectively wound around two arms of the closed U-shaped magnetic core.
As a further complement to the above solution, the T-shaped magnetic block comprises a vertical portion and a horizontal portion; the block-shaped magnetic core is provided with a mounting hole, the vertical part of the T-shaped magnetic block is vertically inserted into the mounting hole, and the horizontal part of the T-shaped magnetic block is detachably arranged in the groove of the base.
As a further complement to the above, the flat coil is a flat copper coil.
As a further supplement to the above scheme, a first pin is arranged on the block-shaped magnetic core, and one end of the flat coil wire tail is welded on the first pin; the base is provided with a second pin, and one end of the flat coil wire head is directly bent and welded on the second pin.
As a further complement to the above, the closed U-shaped magnetic core and the block-shaped magnetic core are bonded to the base by an adhesive.
The beneficial effects are that: compared with the prior art, the utility model relates to an available regulation T type magnetic core of assembled common differential mode inductor and cubic magnetic core's specification adjusts the proportion of product common mode inductance volume and differential mode inductance volume, under the same spatial condition, can reach the effect of optimizing the volume space, has improved space utilization.
