Abstract
The utility model discloses an annular inductor which comprises a first coil, a second coil, a closed-magnetic-circuit annular magnetic core and a fixing support seat. The fixing support seat comprises a base seat and a vertical support frame, and the vertical support frame is perpendicular to the base seat. An insulating layer wraps the magnetic core, the support frame is fixedly arranged on the annular magnetic core in sleeved mode along the diameter direction of the magnetic core, the first coil and the second coil are symmetrically wound on the annular magnetic core on two sides of the support frame, four pins are arranged on the base seat, and two leading-out terminals of the first coil and two leading-out terminals of the second coil are connected with the pins. The annular inductor has the advantages that the structure is simple, the size is small, the inductive value is high, the price is low, the voltage-withstanding requirements of an output circuit of a high-power amplifier can be met, noise waves generated in the process of transmission can be removed, the property is stable, and the like.
Description
Technical field
The utility model relates to a kind of inductor, specifically relates to a kind of toroidal inductor.
Background technology
In many electronic equipments, its circuit or device itself all can produce the electromagnetic interference of some, particularly electronic equipment tends to miniaturization gradually, a plurality of electronic components are closely by being crowded together, electromagnetic interference problem more easily occurs, and this electronic equipment produces the normal operation that excessive electromagnetic interference can be disturbed other electronic equipments on every side, perhaps produces the phase mutual interference with other electronic installations.In electronic equipment, often use inductor, it is anti-interference element commonly used in the electronic circuit, for high-frequency noise good shielding action is arranged, still, the extension of electronics miniaturization trend, and the application of the output filter circuit of high power amplifier, Secretary has all been proposed for the volume of inductor, withstand voltage contour performance, in addition, existing inductor generally includes magnetic core and the coil of direct winfing on magnetic core, is unfavorable for that inductor directly is fixed in the electronic circuit.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of toroidal inductor, have simple in structure, volume is little, and inductance value is high, and price is low, high power amplifier output circuit requirement of withstand voltage can be satisfied, the clutter that produces in the transmission can be removed, and the multiple advantage such as stable performance.
The technical solution of the utility model is achieved in that
A kind of toroidal inductor, comprise the first coil, the second coil, closed magnetic circuit toroidal core and hold-down support, described hold-down support comprises the vertical supports of base and vertical described base, described magnetic core is coated with insulating barrier, described support is fixed on the described toroidal core along described core diameter direction cover, described the first coil and described the second coil symmetry are wound on the toroidal core of described support both sides, described base is provided with four pins, and two leading-out terminals of described the first coil and the second coil are connected with described pin respectively.
As further improvement of the utility model, two leading-out terminals of corresponding described the first coil and the second coil, described support is provided with catch, and described catch can be located the appearance end of described the first coil and described the second coil.
As further improvement of the utility model, described toroidal core is FERRITE CORE.
As further improvement of the utility model, described toroidal core is a kind of of annulus magnetic core, square toroidal core and oval ring magnetic core.
The beneficial effects of the utility model are: compare with the prior art inductor, the utility model toroidal inductor has simple in structure, and volume is little, and inductance value is high, price is low, high power amplifier output circuit requirement of withstand voltage can be satisfied, the clutter that produces in the transmission can be removed, and the multiple advantage such as stable performance, in addition, the utility model magnetic core is FERRITE CORE, has the characteristics such as high withstand voltage properties and shape stable performance, thereby has guaranteed the stability of product quality.
