Description
Technical field
The utility model relates to a kind of plug-in type power inductance.
Background technology
The plug-in type power inductance is widely used at appliance fields such as computer main boards, use maximum traditional inductance that remains magnetic core and coil composition at present, its magnetic core is an annular, because its periphery does not have radome, therefore electromagnetic radiation is bigger, other components and parts is produced disturb; And the assembling process of its coil and magnetic core undertaken by craft fully, and production efficiency is low.A kind of inductance with function of shielding has also appearred on the market, its radome and magnetic core are two part E shape assemblies, be that radome and magnetic core are that integral structure and dimidiation are formed, because the shape of coil molding and the groove of E shape assembly do not match easily, like this when coil is installed, the assembling and positioning difficulty, and assembly problem also can cause the inductance performance poor stability.
So existing product has the following disadvantages: electromagnetic radiation is big, production efficiency is low, assembling and positioning is difficult, stability is poor.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, and the plug-in type that a kind of electromagnetic radiation is less, production efficiency is high, assembling and positioning is easy, stability is good power inductance is provided.
The technical scheme that the utility model adopted is: the utility model comprises magnetic core, has the coil of insulating barrier, it also comprises radome, filler, described magnetic core is bar-shaped, described coil is socketed on the described magnetic core, described radome ladle cover is outside described magnetic core and described coil, described filler is filled in the space in the described radome, and described coil stretches out two pins outside described radome.
Described radome comprises end face, side, and described end face is connected with described side.
The side of described radome is provided with two breach in two described pin places.
Described filler comprises resin material.
Described magnetic core, described radome adopt soft magnetic material to make.
The beneficial effects of the utility model are: because the utility model comprises radome, described radome ladle cover is outside described magnetic core and described coil, can the noises such as electromagnetic radiation that inductance produces be shielded, effectively prevent from other components and parts are produced interference, so the utility model electromagnetic radiation is less; Because magnetic core described in the utility model is bar-shaped, described coil is socketed on the described magnetic core, and described coil can wind the line by machine, so the utility model assembling and positioning is easy, can not change owing to assembly problem causes inductance performance stability, its stability is good, the production efficiency height.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises magnetic core 1, the coil 2 that has insulating barrier, radome 3, filler 4, described magnetic core 1 is bar-shaped, the cross section of described magnetic core 1 is a Long Circle, can certainly adopt other shape, as circle, oval, oval etc., described coil 2 is socketed on the described magnetic core 1, described radome 3 ladle covers are outside described magnetic core 1 and described coil 2, described filler 4 is filled in the space in the described radome 3, described coil 2 stretches out two pin 2a outside described radome 3,2b, described radome 3 comprises end face 31, side 32, described end face 31 is connected with described side 32, structure is separately adopted in described end face 31 of present embodiment and described side 32, so more help assembling, the structure of one also can be adopted in certain described end face 31 and described side 32, but the trade mark of printed inductance on the described end face 31, pattern and literal such as relevant art parameter, help identification, convenient production, deposit and use, the side 32 of described radome 3 is in two described pin 2a, the 2b place is provided with two breach 3a, 3b, two described breach 3a, 3b can prevent two described pin 2a, 2b contacts with described radome 3 and the short circuit that produces, also has the effect that heat that the described coils in the described radome 32 are produced dispels the heat, described filler 4 adopts resin material, the effect of described filler 4 is the effects that make described magnetic core 1 and described coil 2 be fixed in the described radome 3 and play insulation, described magnetic core 1, described radome 3 adopts soft magnetic material to make, can certainly adopt other permeability magnetic material to make, in addition, make the plug-in type power inductance of same size, adopt structure of the present utility model can save precious metals such as a large amount of copper cash than traditional structure.
The utility model belongs to field of electrical components, can be applicable to computing information and electric equipment products.
