Abstract
The utility model relates to a filter element, which comprises an annular insulating shell, an annular magnetic core accommodated in the insulating shell and a coil winded on the insulating shell. The annular insulating shell consists of a pair of annular cover bodies with same structures. The filter element has simple structure and low cost.
Description
[technical field]
The utility model relates to a kind of filter element, particularly relates to the filter element that is applied to power supply.
[technical background]
The prior art relevant with present patent application sees also TaiWan, China patent M329869 number of on October 9th, 2007 bulletin, and the prior art has disclosed a kind of filter, and this filter comprises a drum stand.This drum stand comprises a housing and a barrier structure.The annular lid that be provided with housing a hollow region, an annular trough body and match with annular trough body, annular trough body can ccontaining magnetic core.Annular trough body comprises an inwall, and two relative positions respectively are provided with two parallel ribs on this inwall, forms groove between these two fins.The annular lid is provided with the convex of two relative positions, and this convex is provided with a breach.Barrier structure comprises a horizontal part and a vertical component effect, and vertical component effect uprightly extends from horizontal part.Vertical component effect passes hollow region and matches with annular lid, and this vertical component effect is fixed in the breach of the groove of annular trough body inwall and annular lid convex, and horizontal part butt annular trough body housing is divided into two coiling zones, twines for two coils respectively.
The drum stand of the filter that above prior art disclosed is made of annular trough body, annular lid and three different parts of barrier structure, complex structure, and the production cost height, thereby be necessary to design a kind of simple in structure and filter element that cost is low.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of simple in structure and filter element that cost is low.
For solving above technical problem, the utility model adopts following technical scheme: a kind of filter element, it comprises that a ring-type insulation shell, is contained in the ring-shaped magnetic core in the insulation shell and is wound in coil on the insulation shell, and the ring-type insulation shell is made up of the identical annular cover of a pair of structure.
With respect to prior art, the insulation shell of the utility model filter element is made up of the identical annular cover of a pair of structure.This filter element is simple in structure and production cost is low.
[description of drawings]
Fig. 1 is the stereogram that meets filter element of the present utility model.
Fig. 2 is the three-dimensional exploded view of filter element shown in Figure 1.
[embodiment]
See also Fig. 1 and shown in Figure 2, the utility model filter element 100 comprises circular insulation shell 2, be contained in the circular magnetic core 4 in the insulation shell 2 and be wound in two groups of coils 6 (only being illustrated in Fig. 1 for making illustrative simplicity) on the insulation shell 2.
See also Fig. 1 and shown in Figure 2, insulation shell 2 comprises two circular lids 21 that structure is identical, this lid 21 comprises that one is positioned at the hollow region that partition wall 211, an outer wall 212, an inwall 213 and inwall 213 on circular lid 21 diameters surround, and partition wall 211 is separated into first winding region 214 and second winding region 215 with hollow region.The height of the inwall 213 of first winding region 214 is greater than the height of the inwall 213 of second winding region 215, and the height of partition wall 211 that surrounds first winding region 214 is greater than the height that surrounds second winding region, 215 partition walls 211.Lid 21 outer walls 212 form an annular receiving space 216 in order to accommodate circular magnetic core 4 with inwall 213.First winding region, 214 outer walls 212 are provided with groove 217 near a lateral edges of receiving space 216, second winding region, 215 outer walls 212 are provided with raised line 218, the shape of this raised line 218 and groove 217 identical and the position of raised line 218 and the position symmetries of groove 217 near a lateral edges of receiving space 216.
When assembling this filter element 100, earlier magnetic core 4 is packed in the circular lid 21, again two circular lids 21 are matched.At this moment, the inwall 213 of two lids 21 and partition wall 211 mutual butts form a barrier structure, and the raised line 218 of the outer wall 212 of a lid 21 is clasped mutually with the groove 217 of another lid 21.
In this filter element 100, two circular lid 21 structures are identical, the parts that only need in process of production to make a kind of form get final product, the partition wall 211 of two lids 21 and inwall 213 mutual butts formation barrier structures are divided into first winding region 214 with insulation shell 2 and second winding region 215 twines for two groups of coils 6 respectively.This filter element 100 is simple in structure, and cost is low.
