Magnetic Shielding Effectiveness, so as to solve the deficiency of prior art.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used is, a kind of Novel chip inductor knot
Structure, including base portion, the magnetic core on base portion and the coil group that is wrapped on magnetic core；The magnetic core is included positioned at center
The framework of core and fixed core, the core is the thick column structure in middle thin two ends, and coil group is wrapped on the core；
Coil group has a pair of outlet terminals, and the end of outlet terminal is connected with a pair of conductive terminal, and outlet terminal is designated as first and goes out
The end of line terminals and the second outlet terminal, the first outlet terminal and the second outlet terminal is connected to the first conducting terminal
With the second conducting terminal；Open up jagged on the relative two side wall of the framework, the first conducting terminal and the second conducting end
Son stretches out from the two gap positions respectively；First conducting terminal and the second conducting terminal are platy structure.
Further, core is the middle thin thick column structure in two ends, and column structure the radian that caves inward of side
Less than 10 degree.In addition, column structure is cylindric or elliptic cylindrical shape, preferably elliptic cylindrical shape structure.
Further, the center of the core is to be set at prism-shaped hollow structure, and the corresponding position of the base portion
There is prism-shaped raised, after installation, the prism-shaped projection of base portion is just placed in the prism-shaped hollow structure of core central.
Further, a shielding piece is pasted with the base portion, it is preferred that the shielding piece is circular ring structure（Annulus or
Elliptical ring）, and set, the width of circular ring structure around base portion center（Exradius-inner circle radius）It is more than
1mm.Shielding piece can well avoid interference the generation with self-excitation phenomena, play good shield effectiveness.
Novel chip inductor structure of the present utility model uses such scheme, compared with prior art, during core is changed to
Between the thin thick column structure in two ends, can be by whole chip inductor boil down to flat, so as to whole encapsulation can further be reduced
Size.And coil group be wrapped in the middle thin thick column structure in two ends can also and meanwhile prevent chip inductor clashed into or
Rock rear coil displacement.In addition, conducting terminal is changed into platy structure, it is possible to increase its bonding area, to ensure the reliability of welding
Property.Meanwhile, a shielding piece is set by simple, you can the generation with self-excitation phenomena is cleverly avoided interference, with good
Magnetic Shielding Effectiveness.Simple structure of the present utility model, it is easy to accomplish, with good practicality.
