Magnetic sheet, axle center column three form an I-shaped structure, wherein further including having coil, the coil uses flat structure, institute
It states coil and is wound on axle center column surface around mode using vertical, the surface of the bottom magnetic sheet is provided with SMD devices, and coil goes out payment to a porter
It is electrically connected with SMD devices.
Specifically, the bottom magnetic sheet is additionally provided with SMD pads, and the SMD devices are arranged on SMD pads and SMD devices
Part is electrically connected.
The beneficial effects of the utility model are：It uses multiply or single cord instead flat wire to stand around structure, inductance will be reduced
Device whole height, and current density can be increased, low-temperature-rise is dropped, turn-to-turn capacitance may further be improved, is suitble to batch-automated
Production, reduces manufacturing cost, applied widely；By the way that SMD devices are arranged in bottom magnetic plate surface, to improve space utilization
Rate, convenient for, directly with the pad solder on pcb board, adapting to the development of Current electronic product by the SMD devices of bottom magnetic plate surface.

Specific implementation mode
It please refers to Fig.1 shown in -3, the utility model is about a kind of flat I-shaped inducer, including I-type magnetic core, institute
It includes top magnetic sheet 11, bottom magnetic sheet 13, axle center column 12 to state I-type magnetic core 1, and one end of the axle center column 12 is arranged at top
The shaft core position in bottom magnetic sheet 13, the top magnetic sheet is arranged in the shaft core position of magnetic sheet 11, the other end of the axle center column 12
11, bottom magnetic sheet 13,12 three of axle center column form an I-shaped structure, further include having coil 2, and the coil 2 is using flat
Formula structure, the coil 2 are wound on 12 surface of axle center column using vertical around mode, and the surface of the bottom magnetic sheet 13 is provided with SMD devices
The payment to a porter that goes out of part, institute's coil is electrically connected with SMD devices, and the bottom magnetic sheet 13 is additionally provided with SMD pads, the SMD devices
It is arranged on SMD pads and SMD devices is electrically connected.
The utility model is used multiply or single cord instead flat wire and is stood around structure, will reduce inductor whole height, and can
To increase current density, low-temperature-rise is dropped, turn-to-turn capacitance may further be improved, is suitble to batch automatic production, reduce manufacture
Cost, it is applied widely；By the way that SMD class devices are arranged in bottom magnetic plate surface, to improve space availability ratio, Current electronic is adapted to
Product develops.
Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model
Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this
The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
It protects in range.
