Abstract
The utility model discloses a U type magnetic core, including a crossbeam, the crossbeam both ends are provided with vertical stabilizer blade, the crossbeam is tetragonal prism shape, the stabilizer blade is cylindrical, there is the chamfer on the arris of crossbeam, there is the wire casing of following stabilizer blade extending direction and seting up on the stabilizer blade. The U type magnetic core who has above -mentioned structure carries out the chamfer through the crossbeam to tetragonal prism shape and handles, and the wire is avoided cutting off by its edges and corners that passivate in coiling and use. And utilize the metallic channel that sets up on the stabilizer blade to walk the line, avoid the wire in disorder or scatter. Improve the article looks of product, increased the incorruptibility of product.
Description
Technical field
The utility model relates to a kind of U-shaped magnetic core.
Background technology
Magnetic core refers to the one sintering magnetic metal oxide be made up of various iron oxide mixture.Such as, manganese-zinc ferrite and nickel-Zn ferrite are typical magnetic core array materials.Manganese-zinc ferrite has the feature of high magnetic permeability and high magnetic flux density, and when the frequency lower than 1MHz, has more low-loss characteristic.Nickel-Zn ferrite has high unit area impedance, the characteristic such as low magnetic permeability less than hundreds of, and also produces comparatively low-loss etc. in the frequency higher than 1MHz.FERRITE CORE is used in the coil of various electronic equipment and transformer.
The magnet ring that we see in the power line of electronic equipment or holding wire one end or two ends is at ordinary times exactly common mode choke.Common mode choke can form larger impedance to common-mode interference current, and does not affect (working signal is difference mode signal) to difference mode signal, therefore uses simple and need not consider distorted signals problem.And common mode choke does not need ground connection, can directly be added on cable.Whole bundle cable is just constituted a common mode choke through a ferrite bead, as required, also can by cable on magnet ring around a few circle.The number of turn is more, and the interference suppressioning effect lower to frequency is better, and more weak to the noise suppressed effect that frequency is higher.In Practical Project, the number of turn of magnet ring to be adjusted according to the frequency feature of disturbance current.Usually, when the frequency band of interference signal is wider, can overlap two magnet rings on cable, each magnet ring, around the different numbers of turn, can suppress High-frequency Interference and low-frequency disturbance so simultaneously.From the mechanism of common mode choke effect, its impedance is larger, more obvious to interference suppressioning effect.
U-shaped magnetic core is one comparatively common in existing magnetic core, comprises the leg at crossbeam and two ends.Crossbeam need winding around could form common mode choke.Existing U-shaped magnetic core crossbeam is cubic cylindricality, and its corner angle are very sharp-pointed, are easy to wire-break when coiling.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of U-shaped magnetic core, by the rib on chamfering passivation crossbeam, avoids cutting off wire.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of U-shaped magnetic core, and comprise a crossbeam, crossbeam two ends are provided with vertical leg; Described crossbeam is cubic cylindricality, and described leg is cylindrical; The rib of described crossbeam there is chamfering; Described leg there is the wire casing offered along leg bearing of trend.
Improve as one, described wire casing is arranged on the outside side of leg.Coil is on crossbeam after coiling, and the wire casing cabling of an outside of foot, avoids that wire is in disorder to be scattered.
Improve as one, the chamfering on described crossbeam is 45 ° of corners.Although rounding anti-cutting effect is best, fillet difficulty of processing is large.45 ° of corners, ensureing wire not by under the prerequisite of cutting off, reduce difficulty of processing, improve and add high efficiency.
Usefulness of the present utility model is: the U-shaped magnetic core with said structure, and by carrying out chamfered to the crossbeam of cubic cylindricality, its corner angle of passivation, avoid cutting off wire when coiling and use.And utilize the metallic channel cabling that leg is arranged, avoid wire in disorder or be scattered.Improve the product phase of product, add the durability of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 crossbeam, 2 legs, 3 chamferings, 4 metallic channels.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises a crossbeam 1, and crossbeam 1 two ends are provided with vertical leg 2; Described crossbeam 1 is cubic cylindricality, and described leg 2 is cylindrical; The rib of described crossbeam 1 there is chamfering 3; Chamfering on crossbeam 1 is 45 ° of corners.Described leg 2 there is the wire casing 4 offered along leg 2 bearing of trend.Wire casing 4 is arranged on the outside side of leg 2.。
Wire is wrapped on crossbeam 1, and by metallic channel 4 cabling.Crossbeam 1 after passivation can not damage wire.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
