Description
Technical field
The application is related to a kind of new electronic component, more particularly to a kind of plug-in inductor.
Background technology
Inductor is a kind of energy storage electronic component that wire winds and is made on FERRITE CORE.Plug-in inductor is one
Plant common inductor structure.Plug-in inductor is mainly used in the circuits such as Switching Power Supply, communication, filtering.Short pin inductor
About 4 millimeters of guide pin length, be not required to after circuit board is welded on cut off unnecessary guide pin again because of it, save production process and quilt
Extensive use.
The production technology of existing short pin inductor, typically winds enamel-covered wire to be bonded the magnetic core of guide pin long as matrix,
After welded and parcel thermal contraction casing tube, then guide pin is cut short to 4 millimeters.This production technology cuts guide pin work because existing
Sequence, it is possible to cause the situation of guide pin cause different in size.Particularly when the guide pin more than two of inductance, because that cannot be glued with machine
Connect guide pin and can only be bonded by hand, situations such as guide pin needle gage is inconsistent, guide pin is crooked can be produced, this will increase amendment difficulty and
Workload, product quality and production efficiency are poor.
The content of the invention
The purpose of the application is to provide a kind of short pin inductor, to overcome the shortcomings of existing short pin inductor production technology.
The purpose of the application is achieved through the following technical solutions：
A kind of short pin inductor, including magnetic core, base and coil, described magnetic core are provided with annular groove, the magnetic core bonding
On base, it is characterised in that：In the annular groove of magnetic core, the base bottom is provided with metallic pin to the coil, leads
Pin is connected with corresponding coil, and the magnetic core bottom is provided with circular concave point, and the base top is provided with circular salient point.
Further, base bottom is provided with fulcrum.
Further, base is insulating materials.
Further, inductor outer wrapping thermal contraction casing tube.
The beneficial effect of the application：A kind of short pin inductor guide pin needle gage stabilization is provided, is easy to circuit board fitting, production effect
Rate is high, good product consistency.
Brief description of the drawings
The application is described further below according to accompanying drawing.
Fig. 1 is a kind of short pin inductor described herein.
Fig. 2 is base described herein.
Fig. 3 is magnetic core described herein.
In figure：
1st, magnetic core；2nd, base；3rd, coil；4th, thermal contraction casing tube；5th, guide pin；6th, fulcrum；7th, salient point；8th, concave point.
Specific embodiment
As shown within Fig. 1-3 years, a kind of short pin inductor described in the embodiment of the present application, including magnetic core 1, base 2 and coil 3,
Described magnetic core 1 is provided with annular groove, and the base 2 is bonded on magnetic core 1, it is characterised in that：The coil 3 is wound on magnetic core 1
Annular groove in, the bottom of the base 2 is provided with metallic pin 5, and guide pin 5 is connected with corresponding coil, and the bottom of the magnetic core 1 sets
There is circular concave point 8, the top of the base 2 is provided with circular salient point 7；The inductor is wrapped with thermal contraction casing tube 4.
It is when specifically used, the top of the bottom of magnetic core 1 and base 2 is Nian Jie, the concave point 8 of magnetic core bottom and the salient point of base top
7 are engaged, and by coil 3 in the annular groove of magnetic core 1, the lead that coil 3 is reserved is connected with guide pin 5, inductor outer wrapping
Thermal contraction casing tube 4.
It is to be understood that, the above and specific embodiment are intended to prove the reality of technical scheme provided herein
Using should not be construed as the restriction to the application protection domain.Those skilled in the art in spirit herein and principle, when
Can various modifications may be made, equivalent or change.The protection domain of the application is defined by appended claims.
