Abstract
The utility model discloses an H-shaped inductor which can be applied to various electronic products for screening signals, filtering noise, stabilizing currents and controlling electromagnetic wave interference. The H-shaped inductor comprises a soft magnetic ferrite core, coils which wind the soft magnetic ferrite core horizontally and terminal pins which allow the ends of the coils to be connected. The soft magnetic ferrite core consists of a circular center pillar and circular bosses which are symmetrically arranged at the upper end and the lower end of the center pillar, and the cross section of the soft magnetic ferrite core is of an integrated H shape. The outer side planes of the circular bosses arranged at the upper end and the lower end of the center pillar are respectively provided with two mutually spaced concave type sinking grooves, and the axes of the sinking grooves are parallel to the axis of the center pillar. The terminal pins are two pins which are led out in the same direction from the lower boss of the soft magnetic ferrite core.
Description
One, affiliated technical field:
The utility model relates to a kind of soft magnetic ferrite I-shaped inducer, is fit to be applied to the I-shaped inducer of screening signal, filtered noise, stabling current and the control Electromagnetic Interference of each electronic product, belongs to electronic information field.
Two, background technology:
The I-shaped inducer that China produces at present mainly adopts wire winding, be to flow in the copper cash of electric current coiling on magnetic core, be characterized in that the inductance value scope is wide, the inductance value precision is high, loss is little, and power is large, and manufacture craft is simple, with short production cycle, raw material supply is sufficient, production automation degree is low, production cost is high, be difficult to the shortcomings such as miniaturization but exist.Traditional I-shaped inducer can not adapt to the demand of downstream electronic complete machine.
Three, summary of the invention:
For overcoming the deficiency that existing I-shaped inducer is low in production automation degree, production cost is high, be difficult to miniaturization, the utility model provides a kind of magnetic ferrite magnetic core I-shaped inducer.Not only volume is little, cost is low and be suitable for the high density plug-in mounting for this I-shaped inductive, and has the electrical property effect of high sensibility reciprocal, high Q value, low deviation and low distributed capacitance.
The technical scheme that the utility model technical solution problem adopts is: I-shaped inducer include magnetic ferrite magnetic core, flat on this magnetic core coil and the terminal pin that connects for coil end.Described magnetic ferrite magnetic core by circular center pillar, be symmetricly set on center pillar up and down the round boss at two ends consist of the I shape that its cross section is integrated.The matrix deep gouge that respectively has two spaces and axis to parallel with middle mast axis on the outer side plane of the round boss at two ends about the described center pillar, described terminal pin is two pins that the magnetic core lower convex platform is drawn in the same way.
The beneficial effects of the utility model are: the soft magnetic ferrite I-shaped inducer can improve the intensity behind magnetic permeability, magnetic saturation and the magnetic strength greatly, can satisfy and the direct supporting screening signal that is installed on each electronic product such as computer equipment, communication apparatus, video/audio equipment, consumer electronics product, automatic electronic equipment, telecommunications broadcasting equipment, filtered noise, stabling current and control Electromagnetic Interference.
Four, description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is structure of the present utility model vertical section structural map.
Fig. 2 is structure vertical view of the present utility model.
In the drawings: 1. convex platform 2. coils 3. magnetic cores
4. lower convex platform 5. terminal pins 6. matrix deep gouges
Five, specific embodiments:
I-shaped inductive convex platform matrix deep gouge is for being fixed in the coil winding machine location notch.The wire lash is in the arbitrary terminal pin of magnetic core lower convex platform, introduce and be wound on the single or multiple lift canoe on the center pillar of magnetic core through the corresponding magnetic core lower convex platform of terminal pin matrix deep gouge, through another terminal pin that another matrix deep gouge of magnetic core lower convex platform is drawn and lash is drawn in magnetic core lower convex platform correspondence.Drawing on the wire of two terminal pins has adhesive group corresponding to corresponding deep gouge place heap, so that drawing wire, this obtains the location at magnetic core, the axis of drawing wire parallels with the axis of center pillar and exceeds the magnetic core certain distance, draw on the wire for every and weld corresponding to arbitrary termination of corresponding adhesive group place and wire, magnetic core and wire are wrapped with heat-shrink tube, the material of magnetic core is that initial permeability is 4000 MnZn soft magnetic ferrite, the diameter ratio of center pillar, boss is 1: 1.8-2.0, adhesive adopts epoxyn.This inductor has been realized subminaturization, has inductance value scope and rated current wider range, the better advantage of reliability.
