Description
Technical field
The invention belongs to inductor fields, and in particular to a kind of resonant inductor.
Background technology
Currently, often the LLC small-power powers of See are all to be internally integrated leakage inductance as resonant inductance, but in high-power applications
When, the structure of the less suitable transformer of this mode, design difficulty very great , Now are general in powerful LLC power circuits
There is external separate inductor, generates the demand of resonance at different frequencies with the work of Full foot circuits, but existing resonance is electric
Sensor has the shortcomings that occupied space is big, loss is big and efficiency is low, causes the waste of electric energy.
Invention content
The technical problems to be solved by the invention, which are just to provide, a kind of to occupy little space, small and efficient resonance electricity is lost
Sensor.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of resonant inductor, including series inductance
Device, the parallel inductor being upside down at the top of series reactor and it is connected to the stitch that series reactor bottom is connected with pcb board
Frame is connected with adhesive glue, several air gaps is provided on the magnetic core of parallel inductor between series reactor and parallel inductor.
Further, the spacing of two neighboring air gap is identical.
Further, the coil of parallel inductor and series reactor is silk-covered wire.
Further, it is both provided with Kapton Tape outside the coil of parallel inductor and series reactor.
Further, the stitch being connected with the coil of parallel inductor and series reactor, coil are provided on stitch frame
End be enclosed with Teflon casing.
Compared with prior art, the beneficial effects of the invention are as follows：
By the top that parallel inductor is inverted in series reactor product so that resonant inductor is in pcb board circuit
In occupy little space, for the limited PCB circuit board in compact-sized, space, which can effectively reduce resonant inductor institute
The space of pcb board is accounted for, several air gaps are provided on the magnetic core of parallel inductor, when resonant inductor passes through high current, gas
Gap can effectively reduce the Wen Sheng of parallel inductor at work.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the stereogram at one visual angle of resonant inductor of the present invention；
Fig. 2 is the stereogram at another visual angle of resonant inductor of the present invention.
Wherein：1, series reactor；2, parallel inductor；3, stitch frame；4, stitch；5, silk-covered wire.
Specific implementation mode
A kind of embodiment of resonant inductor of the present invention is described further referring to figs. 1 to Fig. 2.
A kind of resonant inductor, including series reactor, the parallel inductor that is upside down at the top of series reactor and company
It is connected on the stitch frame that series reactor bottom is connected with pcb board, passes through work for dispensing glue between series reactor and parallel inductor
Skill is bonded, i.e., before the assembling for carrying out resonant inductor, both series reactor and parallel inductor independently separate, can be with
Coiling is first separated, after series reactor and parallel inductor assemble magnetic core respectively and test passes through, then carries out dispensing
It is fixed, facilitate the coiling of coil, parallel inductor to be inverted in the top of series reactor product so that resonant inductor is in PCB
Printed line occupies little space in road, and for the limited PCB circuit board in compact-sized, space, which can effectively reduce resonance electricity
The space of pcb board shared by sensor is provided with several air gaps on the magnetic core of parallel inductor, when resonant inductor passes through high current
When, air gap can effectively reduce the Wen Sheng of parallel inductor at work, and equidistant air gap is more convenient for processing.
The coil of parallel inductor and series reactor is all made of silk-covered wire and carries out coiling, greatly increases effectively cutting for conductor
Area reduces Kelvin effect, improves the quality factor of inductance, that is, reduces the loss of resonant inductor, improve resonant inductor
Efficiency.
Kapton Tape is both provided with outside the coil of parallel inductor and series reactor, be provided on stitch frame with simultaneously
The stitch that connection inductor is connected with the coil of series reactor, overhang are enclosed with Teflon casing, Kapton Tape
Have many advantages, such as that high temperature resistant, tensile strength are high, chemical resistance is good, without residue glue, outside coil, Teflon casing has excellent for winding
Chemical stability, corrosion resistance, sealing property, high lubrication, non-stickiness, electrical insulation and good anti-aging endurance, the two can be with
Greatly improve the insulating properties of coil.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
