Abstract

The utility model relates to magnetic cores in choking coils, filters, electronic transformers and other inductors and provides a novel UUI magnetic core. The novel UUI magnetic core comprises one I-shaped combination center post magnetic element and two U-shaped side post magnetic elements, wherein the I-shaped combination center post magnetic element consists of two T-shaped magnetic elements; a straight arm is arranged in each U-shaped side post magnetic element; two folding arms are respectively arranged at two ends of each straight arm; outward end faces of the folding arms of the two U-shaped side post magnetic elements are respectively attached to two opposite side surfaces of rectangular magnets at two ends of the I-shaped combination center post magnetic element, so that the I-shaped combination center post magnetic element and the two U-shaped side post magnetic elements are butted to form the UUI type magnetic core. Compared with the traditional EE type, EI type, EC type and PQ type magnetic core, the novel UUI magnetic core has the beneficial effects that when the novel UUI magnetic core is used in the inductor, the consumption of copper materials is reduced, and the quality factor also can be improved.

Description

A kind of novel UUI magnetic core
Technical field
The utility model relates to the magnetic core in the inductance components such as choke, filter and electronic transformer, relates in particular to UUI type magnetic core, can be used as the core component use of making UUI type magnetic electronic element.
Background technology
Traditional coil class inductance component generally coordinates bobbin to form around upper enamelled wire by EE type magnetic core or EI type magnetic core.In order to prevent that magnetic saturation phenomenon from occurring, need in magnetic circuit, be provided with magnetic air gap, magnetic air gap is placed in the center pillar of magnetic core conventionally, dispersing flux is mainly present near magnetic air gap, dispersing flux makes near coiler part air gap lose the transformation of " electricity-magnetic ", and near coil sections air gap only plays filling effect.The larger dispersing flux of air gap amount is just larger, and the coil of invalid filling is also just more, and the magnetic line of force, vertically through line bag, causes certain power loss simultaneously.Above-mentioned reason causes the increase of device self copper resistance and copper loss, and the power consumption of device is raise, and waste electric energy and copper material, reduce useful life.
In order to reduce manufacturing cost, conventionally rectangle is processed into in the cross section of magnetic core, so can reduce manufacturing cost, facilitate again and in the time manufacturing inductance component, carry out magnetic core assembling.But the identical rectangle center pillar girth of sectional area, than the Zhou Chang great of circular center pillar, has increased the use amount of copper cash.
Summary of the invention
The purpose of this utility model is: provide a kind of and use in inductance component, can save the copper material consumption of inductance component and improve the magnetic core of inductance component quality factor (being Q value).
The technical solution of the utility model is achieved in that
A kind of novel UUI magnetic core, is characterized in that, comprises an I font combination center pillar magnetic part and two U font side column magnetic parts; Described I font combination center pillar magnetic part is made up of two T font magnetic parts; Described U font side column magnetic part is provided with a straight-arm, is respectively equipped with two folding arms at the two ends of straight-arm; By the export-oriented end face of two U font side column magnetic part folding arms, be affixed to respectively two opposite flanks of I font combination center pillar magnetic part two ends rectangular magnet, make I font combination center pillar magnetic part dock formation UUI type magnetic core with two U font side column magnetic parts.
The beneficial effects of the utility model are:
Usefulness is compared with traditional EE type, EI type, EC type and PQ type: in inductance component, use the utility model, and the one, save copper material, the 2nd, improve quality factor (being Q value).
Below in conjunction with drawings and Examples, the utility model is described in detail.
Brief description of the drawings
The UUI magnetic core schematic diagram of Fig. 1: embodiment 1;
The UUI magnetic core exploded view of Fig. 2: embodiment 1;
The UUI magnetic core schematic diagram of Fig. 3: embodiment 2;
The UUI magnetic core exploded view of Fig. 4: embodiment 2.
Embodiment
embodiment 1
A kind of novel UUI magnetic core, referring to Fig. 1 and Fig. 2, is characterized in that, comprises an I font combination center pillar magnetic part 1 and two U font side column magnetic parts 2; Described I font combination center pillar magnetic part is made up of two T font magnetic part 1-1; Described U font side column magnetic part is provided with a straight-arm, is respectively equipped with two folding arms at the two ends of straight-arm; By the export-oriented end face of two U font side column magnetic part folding arms, be affixed to respectively two opposite flanks of I font combination center pillar magnetic part two ends rectangular magnet, make I font combination center pillar magnetic part dock formation UUI type magnetic core with two U font side column magnetic parts.
In the present embodiment, described T font magnet is integral structure, comprises a rectangular magnet 1-1-1, and is located at the semicircle cylindrical magnet 1-1-2 in rectangular magnet.In the time making inductance component, by on the winding axle of coil winding online design ring framework, then the semicolumn magnet of two T font magnetic parts is inserted in hollow hole at the two ends of self-inductance skeleton respectively, two semicolumn magnets are combined into a cylindrical magnet in skeleton hollow hole, two T font magnetic parts are combined and formed I font combination center pillar magnetic part.In order to prevent the generation of magnetic saturation phenomenon, between the side at I font combination center pillar magnetic part both ends and U font side column magnet, be provided with air gap medium, air gap medium is made by PET material.Outside at I font combination center pillar magnetic part and two U font side column magnetic parts is closely wound around with insulating tape, makes between I font combination center pillar magnetic part, two U font side column magnetic parts and air gap medium in conjunction with obtaining closely, firmly.
embodiment 2
A kind of novel UUI magnetic core, referring to Fig. 3, Fig. 4 and embodiment 1.The present embodiment is similar to Example 1, and its difference is: T font magnetic part comprises a rectangular magnet 1-1-1, and is arranged on the short cylindrical shape magnet 1-1-2 in rectangular magnet.
