Abstract
The invention discloses a kind of flat wire bar magnet inductance, including the coil windings that the skeleton with pin, the magnetic core that is installed on skeleton and wounded core are set, two pins of the coil windings are connected with pin, and the coil windings use flat copper wire coiling.The present invention has the good advantage of high-power low clearance high frequency anti-EMI filter.
Description
Technical field
The present invention relates to bar magnet inductance, using on filter function power supply board is realized.
Background technology
At present, traditional round wires wire winding, causes that inductance volume is larger, and heat dissipation effect is bad.
The content of the invention
The technical problems to be solved by the invention are just to provide a kind of flat wire bar magnet inductance, reduce volume, improve heat dissipation effect
Fruit.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of flat wire bar magnet inductance, including with drawing
The coil windings that the skeleton of foot, the magnetic core being installed on skeleton and wounded core are set, two pins of the coil windings
It is connected with pin, the coil windings use flat copper wire coiling.
The technical solution adopted by the present invention, has the advantages that：
1st, using flat wire independence winding mode, this structure space utilization rate is high, and coil tight ness rating is good, and parasitic capacitance is small,
EMC effects are good.
2nd, using flat wire sky coiling form.The degree of automation is high, and so design simplifies wire winding, and assembling is simple.
Both ends pin portion overcomes bar magnet inductance using this line leading foot away from bad control towards being connected with the pin on magnetic core on material
Weakness.
3rd, for entirety, the structure of flattening so that the area-volume ratio increase of product, the planar structure of spiral winding
Air passage can be formed, the bigger that operating point when being easier to radiate than cylinder enameled wire, therefore causing the magnetic core to work can take, this
Sample can more reduce magnetic core size and number of winding turns.
4th, it is minimum with size D.C. resistance using flat copper wire coiling, it is ensured that the resistance to current inductance value range of decrease is smoothed out and born
Instantaneous large-current ability is good.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the structure diagram of the present invention.
Embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below with reference to the accompanying drawings and the present invention will be described in detail in conjunction with the embodiments.
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Below
Description only actually at least one exemplary embodiment is illustrative, is never used as to the present invention and its application or makes
Any restrictions.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of flat wire bar magnet inductance, including the skeleton with pin 3, the magnetic core 1 that is installed on skeleton with
And the coil windings 2 that wounded core is set, two pins of the coil windings are connected with pin, the coil windings are using flat
Flat copper wire winding.
The inductance has the good advantage of high-power low clearance high frequency anti-EMI filter, suitable for power supply unit, PC and its
Application of the direct current to DC rectifier on power circuit in its palm electronic equipment.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, and is familiar with
The those skilled in the art should be understood that the present invention includes but not limited to attached drawing and interior described in embodiment above
Hold.The modification of any function and structure principle without departing from the present invention is intended to be included in the scope of claims.
