Description

A kind of flat wire is vertical around high-power inductance

Technical field

Inductive technologies field is the utility model is related to, more particularly to a kind of flat wire is stood around high-power inductance.

Background technology

The manufacture craft of high-power inductance traditional at present substantially divides three kinds, and one kind is contact pin type, is done using body wire Pin realizes that product power maximizes, but labor intensive, must can not realize automated job by artificial plug-in unit during use. Another kind for SMD (Surface Mounted Devices, surface mount device) it is SMD, by increasing tablet, after welding into Type is SMD pads, can realize SMT (Surface Mount Technology, surface mounting technology) automatic chip mounting during operation, but Product ontology and pin have pad, inadequate so as to produce open circuit and contact surface, can not effectively play peak power, and because Weld tablet and body conductor introduction must be cut, formed and wasted, and the hidden danger of sealing-off be present.It is also a kind of to flatten formula, i.e., Scolding tin forms pad again after the both ends of coil are flattened, and its both ends makes its veneer become big and irregular, it is necessary to enter one because of deformation Trimming is walked, and the conductor effective interface agent at deformation diminishes and causes effective power step-down, the people that its whole process expends Power material resources are larger, can not also carry out automated job.

At the same time, referring to Fig. 1, it is existing flat wire coil schematic diagram, flat wire by flat around being coiled into coil, The penetration hole diameter surrounded made of such a method in the middle part of flat wire coil is smaller, and the diameter of the corresponding bar magnet for being positioned over perforation is also It is corresponding to reduce, when the radius of bar magnet is fixed, the power to increase inductance, then need to increase the winding number of turn of coil so that line Circle is very crowded, and the poor radiation that works long hours, impedance increase.

Utility model content

It is of the present utility model to be directed to prior art problem, there is provided a kind of flat wire is vertical around high-power inductance, and it includes shell Body, bar magnet and flat wire coil, wherein housing are cuboid, and its bottom surface is in open state, and the both sides of housing have groove respectively, Bar magnet is arranged in housing, and the end face of flat wire coil is wound in the outside of bar magnet and the both ends of flat wire coil and is arranged in respectively Groove and the bottom surface for being exposed to housing, the both ends of flat wire coil are respectively flat.

According to the embodiment of the application, above-mentioned two grooves are located at identical horizontal line.

According to the embodiment of the application, above-mentioned two grooves are located at different horizontal lines.

According to the embodiment of the application, above-mentioned bar magnet is column nickel-zinc ferrite.

Compared with prior art, the application can be obtained including following technique effect：

The flat wire of the application is vertical simple around high-power induction structure, easy to assembly, reduces volume, passes through flat wire coil Both ends be directly realized by SMT operations, save manufacturing procedure, improve production efficiency；Simultaneously flat wire it is vertical around loop construction, increase The diameter of thiol, the bigger bar magnet of diameter can be accordingly selected, reduce the number of turns of coil, the radiating effect of coil is changed Kind, loss reduces, and impedance reduces, inductance value and the increase of resistance to electric current, and the hidden danger such as short circuit when avoiding work.
