Abstract
The utility model discloses an electromagnetic coil, including magnetic core, cavity skeleton, wire, the wire is around form the coil on the cavity skeleton, the cavity position at the cavity skeleton is installed to the magnetic core, the magnetic core includes major part section, microcephaly's section, changeover portion, the left end face of changeover portion is connected to the right -hand member face of microcephaly's section, the left end face of major part section is connected to the right -hand member face of transition face, the up end and/or the lower terminal surface of changeover portion are the curved surface section to the indent. The utility model discloses at the soft magnetic ferrite magnetic core that original coil skeleton's cavity position one end of installation strengthened, this magnetic core is compared with present iron core, and the total length does not increase, has nevertheless increased volume, quality, and the inductance value of coil consequently can the grow, adds most magnetic core shape and has the curved surface section, and this curved surface section accords with magnetic line of force nature curve and distributes, and the magnetic flow is most effective, can increase the electromagnetic coil inductance value by furthest, has improved the inductance value of inductance component.
Description
Technical field
This utility model relates to a kind of solenoid.
Background technology
Existing solenoid is made up of hot-wire coil, hollow member, strip iron core, and electrified wire is wound on the skeleton of hollow formation coil, and strip iron core is arranged on the hollow part of skeleton.
The important parameter of solenoid is inductance value, and the inductance value of solenoid is proportional with iron core quality.In order to improve the inductance value of solenoid, iron core is made as far as possible big and the longest；But, skeleton hollow section is limited, and the length of iron core requires it is also limited due to device miniaturization.This just gives produce high inductance coil to cause difficulty.
Summary of the invention
This utility model is for the problems referred to above, a kind of solenoid is provided, use the design of big head section, changeover portion, little head section one, the upper surface of changeover portion and/or lower surface arrange the curved sections concaved, the mating shapes that curved sections is distributed with magnetic line of force natural curve, this design can improve the inductance value of solenoid under conditions of not increasing existing core length.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: a kind of solenoid, including magnetic core, hollow member, wire, described wire is wound on hollow member formation coil, described magnetic core is arranged on the hollow part of hollow member, described magnetic core includes big head section, little head section, changeover portion, the right side of described little head section connects the left side of changeover portion, the right side of described transition face connects the left side of big head section, and the upper surface of described changeover portion and/or lower surface are the curved sections concaved.
Described big head section, little head section and changeover portion are integral type structure.
The upper surface of the outer rim of described hollow member is not higher than the upper surface of big head section, and the lower surface of the outer rim of hollow member is not less than the lower surface of big head section.
The maximum gauge that described wire is wound around is not more than the height of the outer rim of hollow member.
Described magnetic core is magnetic ferrite magnetic core.
The beneficial effects of the utility model are: this utility model is at the magnetic ferrite magnetic core of hollow position one enlarged at one end of installation of original coil rack, this magnetic core is compared with existing iron core, total length does not increase, but increasing volume, quality, the inductance value of coil is therefore, it is possible to become big, and the core shapes of enlarged portion is with curved sections, this curved sections meets the distribution of magnetic line of force natural curve, magnetic flux efficiency is the highest, it is possible to increases solenoid inductance value to greatest extent, improves the inductance value of inductance component.
