Description
Technical field
The utility model belongs to inductor field, 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.
Utility model content
Technical problem to be solved in the utility model be just to provide it is a kind of occupy little space, be lost it is small and efficient humorous
Shake inductor.
In order to solve the above technical problems, the utility model adopts the following technical solution：A kind of resonant inductor, including series connection
Inductor, the parallel inductor being upside down at the top of series reactor and it is connected to what series reactor bottom was connected with pcb board
Stitch frame is connected with adhesive glue, several is provided on the magnetic core of parallel inductor between series reactor and parallel inductor
Air gap.
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 utility model has the beneficial effects that：
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 utility model is further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the stereogram at one visual angle of the utility model resonant inductor；
Fig. 2 is the stereogram at another visual angle of the utility model resonant inductor.
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 utility model 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 the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
