Abstract
The utility model discloses a kind of New single-phase common mode choke, comprise magnetic core, the first winding, the second winding, dividing plate, base plate, first winding and the second winding are in the coiling of magnetic core bilateral symmetry, dividing plate is positioned at the middle part of magnetic core, symmetrical center line along the first winding and the second winding is arranged, and core cross-section is circular arc camber structure.The junction of the first winding and the second winding and base plate adopts epoxy sealing.Novel Magnetic Core Design effectively solves large line when coil winding, unpliant phenomenon, reduces the probability of coil windings breakage simultaneously, and saves coil raw material, reduce cost.
Description
Technical field
The utility model relates to choke structure, particularly relates to a kind of New single-phase common mode choke.
Background technology
Common mode choke is a common mode disturbances suppression device being magnetic core with materials such as ferrites, it is measure-alike by two, the coil that the number of turn is identical is wound on same ferrite toroidal magnetic core symmetrically, form a four-terminal device, large inductance to be presented inhibited for common-mode signal, magnetic flux when flowing through common mode current in choke in magnet ring superposes mutually, thus there is sizable inductance value, inhibitory action is played to common mode current, and when two coils flow through differential-mode current, magnetic flux in magnet ring is cancelled out each other, almost there is no inductance value, so differential-mode current can be passed through undampedly.Therefore common mode choke effectively can suppress common mode interference signal in balanced circuit.
Current choke coil magnet core structure major part for cross section be the loop configuration of rectangle, in coil-winding process, enamelled wire breakage probability is high, the large line of especially little magnetic core through time, enamelled wire not easily bends.
Utility model content
In view of this, the utility model provides a kind of New single-phase common mode choke, improves, efficiently solve the problems referred to above to core shapes.The technical solution of the utility model is achieved in that
A kind of New single-phase common mode choke, comprise magnetic core 1, first winding 2, second winding 3, dividing plate 4, base plate 5, described first winding 2 and the second winding 3 are in the coiling of magnetic core 1 bilateral symmetry, dividing plate 4 is positioned at the middle part of magnetic core, symmetrical center line along the first winding 2 and the second winding 3 is arranged, and described magnetic core 1 cross section is circular arc camber structure.
As improvement, the cross section of magnetic core 1 is the curved surface of rectangle and circular sliding slopes or the curved surface of square and circular sliding slopes or oval calotte.
As improvement, the junction of the first winding 2 and the second winding 3 and base plate 5 adopts epoxy resin 6 to seal.
The beneficial effects of the utility model are embodied in:
One, reduce the probability of coil windings breakage, reduce fraction defective;
Two, effectively solve large line when coil winding, unpliant phenomenon, improves product quality;
Three, save coil raw material, reduce cost.
Accompanying drawing explanation
Fig. 1 is a kind of New single-phase common mode choke of the utility model structural representation;
[critical piece symbol description]
1: magnetic core; 2: the first windings; 3: the second windings; 4: dividing plate; 5: epoxy resin; 6: base plate.
Embodiment
Embodiment below in conjunction with accompanying drawing and this practicality is described further a kind of New single-phase common mode choke of the present utility model.
As shown in Figure 1, a kind of New single-phase common mode choke, comprise magnetic core 1, core material can the preferred iron silicon of the selection of material, iron sial, one or more in ferrite, first winding 2, second winding 3, dividing plate 4, base plate 5, first winding 2 and the second winding 3 are in the coiling of magnetic core 1 bilateral symmetry, bottom is connected with base plate 5, and the junction of the first winding 2 and the second winding 3 and base plate 5 adopts epoxy resin 6 to seal, and prevents electric wire to be oxidized and plays insulating effect.Dividing plate 4 is positioned at the middle part of magnetic core, and the symmetrical center line along the first winding 2 and the second winding 3 is arranged, and described magnetic core 1 cross section is circular arc camber structure.
This circular arc camber is preferably the curved surface of rectangle and circular sliding slopes, square and the curved surface of circular sliding slopes or oval calotte, and under same cross-sectional is amassed, circular perimeter is less than rectangular perimeter, adopts this curved-surface structure, can greatly save coil materials, reduce costs.In addition, when magnetic core magnetic circuit direction cross section is rectangle, easily break at magnetic core internal diameter, external diameter stupefied place coil, smooth curved surface then can address this problem very well.In addition, smooth curved surface effectively solves large line when coil winding, unpliant phenomenon.
