Abstract
The utility model discloses a filter inductance magnet ring, which is characterized in that the filter inductance magnet ring main body is a ring-shaped body; the ratio between the axial length of the ring-shaped body and the outer ring diameter of the ring-shaped body is 0.8 to 1.2: 2; a copper sheet is wrapped on the outer surface of the ring-shaped body; and an enameled wire is enwound around the copper sheet. The novel magnet ring structure has the advantages that the cost is saved, and the performance is reliable when the magnet ring is in operation.
Description
Technical field
The utility model belongs to electric and electronic technical field, relates to a kind of filter inductance magnet ring.
Background technology
Because the power of product reaches existing single magnet ring greatly and can not satisfy the demand, and often adopts two magnet rings to stack the coiling inductance, as shown in Figure 1.Contact-making surface need be fixed with glue when two magnet rings stacked, and still, caused magnet ring integral body to ftracture in apertured place easily because of two single magnet ring discontinuity when the line that winds the line is directly thick, thereby caused making product fraction defective height.
The utility model content
The utility model wants the technical solution problem to provide a kind of filter inductance magnet ring, and this novel magnetic ring structure can be saved cost, and in when work dependable performance.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of filter inductance magnet ring, it is characterized in that the main body of this filter inductance magnet ring is a ring bodies, the ratio of the axial length of described ring bodies and the outer ring diameter of ring bodies is 0.8～1.2: 2, the outer surface of ring bodies is coated with copper sheet, and the copper sheet outside is wound with enamelled wire.
The ratio of the axial length of described ring bodies and the outer ring diameter of ring bodies is 1: 2.
Above-mentioned axial length dimension is the axial length dimension sum of existing 2 single magnet rings.
The beneficial effects of the utility model:
The utility model is equivalent to two single magnet rings are pressed into a ring, so the intensity of the intensity of magnet ring after 2 single magnet rings welding had remarkable improvement, has avoided the quality problems of magnet ring cracking to occur, and therefore, unfailing performance significantly improves when work.
In addition, adopt novel magnetic ring structure of the present utility model, can reduce two-layer insulating varnish thickness, thereby reduce product thickness, and reduce winding length, thereby reduce cost.
Further, coat on the magnetic core behind the copper sheet, can improve the EMI of product like this, and can reduce the different sound of product complete machine again around enamelled wire.
Description of drawings
Fig. 1 is the structural representation of existing magnet ring.
Fig. 2 is a magnet ring structural representation of the present utility model.
The single magnet ring of label declaration: 1-, the ring bodies of 2-novel magnetic ring, 3-copper sheet, 4-enamelled wire.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
As shown in Figure 2, a kind of filter inductance magnet ring is characterized in that, the main body of this filter inductance magnet ring is a ring bodies 2, the ratio of the axial length of described ring bodies and the outer ring diameter of ring bodies is 1: 2, and the outer surface of ring bodies is coated with copper sheet 3, and the copper sheet outside is wound with enamelled wire 4.The axial length dimension of the magnet ring of this novel magnetic ring structure is the axial length dimension sum of existing 2 single magnet rings.
Claims (2)
1. filter inductance magnet ring, it is characterized in that the main body of this filter inductance magnet ring is a ring bodies, the ratio of the axial length of described ring bodies and the outer ring diameter of ring bodies is 0.8～1.2: 2, the outer surface of ring bodies is coated with copper sheet, and the copper sheet outside is wound with enamelled wire.
2. a kind of filter inductance magnet ring according to claim 1 is characterized in that the ratio of the axial length of described ring bodies and the outer ring diameter of ring bodies is 1: 2.
