Description
Technical field
The utility model relates to the magnetic core in the inductance components such as choke and electronic transformer, relates in particular to UUI type magnetic core.
Background technology
Traditional coil class inductance component generally cooperates bobbin to form around last enamelled wire by EE type magnetic core, EI type magnetic core or PM type magnetic core.In order to prevent that the magnetic saturation phenomenon from taking place, need in magnetic circuit, be provided with magnetic air gap, magnetic air gap places the center pillar of magnetic core usually, dispersing flux mainly is present near the magnetic air gap, dispersing flux makes near the coiler part the air gap lose the transformation of " electricity-magnetic ", and near the coil sections the air gap only plays filling effect.The more big dispersing flux of air gap amount is just more big, and the coil of invalid filling is also just more many, and the magnetic line of force vertically passes the line bag simultaneously, causes the certain power loss.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.
Summary of the invention
The purpose of this utility model is: provides a kind of PM of replacement type magnetic core to use at inductor, can save the copper material consumption of inductor, and the UUI type magnetic core that improves inductance component quality factor (being the 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 shape magnet, two U-shaped magnets and two end caps; Described I shape magnet is cylindric, is provided with a fixed via in the center; Described U-shaped magnet magnet is provided with a butterfly-shaped arm, is respectively equipped with folding arm at the two ends of butterfly-shaped arm, and folding arm is the arc column shape, is provided with a jack in the center of butterfly-shaped arm; Described end cap is provided with a base plate, is provided with a centre bore and medium circle at base plate, and the medium circle is circular, and end cap is made close to 1 material by relative permeability.
A kind of novel UUI magnetic core is characterized in that, comprises an I shape magnet, two U-shaped magnets and two air gap media; The two ends of described I shape magnet are provided with two and are round table-like insertion body; Described U-shaped magnet magnet is provided with a butterfly-shaped arm, is respectively equipped with folding arm at the two ends of butterfly-shaped arm, and folding arm is the arc column shape, is provided with a jack that is taper in the center of butterfly-shaped arm, and the diameter of jack internal orifice is greater than the diameter of collar extension; Described air gap medium is horn-like, is provided with a through hole in the middle of the air gap medium, and the air gap medium is made close to 1 material by relative permeability.
The utility model is compared with EE type or PM type conventional cores, has the following advantages:
1. the utility model is saved copper material;
2. the utility model has improved quality factor (being the Q value).
Below in conjunction with drawings and Examples the utility model is described in detail.
