Abstract
The utility model provides a die-cast thin plug-in inductor. A multi-layer conductive coil formed from a metal enameled wire is embedded into a thin magnetic conductor die-cast from metal magnetic powder, so that the volume of the inductor is further reduced and the height thereof on a PCB (Printed Circuit Board) is reduced; and a closed magnetic circuit is capable of bearing higher current and not easy to induce electromagnetic interference.
Description
Technical field
The utility model relates to a kind of inductor, relates in particular to a kind of embedded inductor device.
Background technology
are present, and in small electronic apparatus such as mobile phone, computer, most chip inducers is used in the power circuit etc.Along with development of science and technology, electronic product is day by day to small-sized, multi-functional development, and electronic devices and components market also presents small size, high efficiency development trend, and inductor is as a kind of electronic devices and components commonly used, and the variation of electronic product is had very big influence.
inductor commonly used comprises integral inductor, magnet ring shape inductor; Generally comprise coil and magnetic conductor; That magnetic conductor is generally is cylindrical, I shape and annular etc., no matter be cylindrical, I shape or annular, its coil often all is to be wound in the magnetic conductor outside.
Inductor that
are existing commonly used, its coil and magnetic conductor are not to be the integral type design, structure defective tightness often, and not only volume is bigger than normal, and problem such as inductance value direct current saturation characteristic on the low side, anti-difference is arranged.In addition, because the manufacture craft of these inductors, the extraction location of its electrode and direction receive very big restriction, make the inductor height to reduce.
Summary of the invention
to above problem, and the utility model provides that a kind of volume is little, inductance value is high, be difficult for producing electromagnetic interference and highly lower inductor.
the utility model is realized through following technical scheme.
The slim plug-in unit inductor of
a kind of die casting formula, comprise the die casting of metallic magnetic powder magnetic conductor, embed the conductive coil in this magnetic conductor and two line ends of simultaneously drawing by magnetic conductor.
further, said conductive coil is the enamelled wire coil.
further, said two line ends are towards unification, form the electrode tip of plug-in unit inductor.
further, said magnetic conductor is cylindrical, said two line ends towards with this magnetic conductor axially parallel.
further, said magnetic conductor is cylindrical, said two line ends are towards axially vertical with this magnetic conductor.
The beneficial effect and the advantage of
the utility model.
The slim plug-in unit inductor of a kind of die casting formula that
the utility model provides; The multilayer conductive coil that metal enamel conductor is processed is embedded in the slim magnetic conductor of metallic magnetic powder die casting; The volume of minimize inductance device reduces its height on pcb board further, and closed magnetic circuit; Loaded current is bigger, is difficult for producing electromagnetic interference.
