【Embodiment】
The technical scheme of the embodiment of the present invention is explained and illustrated with reference to the accompanying drawing of the embodiment of the present invention, but under
It is only the preferred embodiments of the present invention to state embodiment, and not all.Based on the embodiment in embodiment, those skilled in the art
Other embodiment is obtained on the premise of creative work is not made, belongs to protection scope of the present invention.
Referring to figs. 1 to 4, the present embodiment is a kind of wave filter, including skeleton 1, is connected with pin 11 on skeleton, in skeleton 1
Provided with magnetic core 2, coiling has coil 3 on the magnetic core 2, and the magnetic core 2 includes being used for the He of the first wrapping post 21 around roll coil 3
One end of second wrapping post 22, one end of the first wrapping post 21 and the second wrapping post 22 is connected by the first connecting pole 23, and first
The other end end of the other end of wrapping post 21 and the second wrapping post 22 is connected by the second connecting pole 24, the first wrapping post 21,
Two wrapping posts 22, the first connecting pole 23, the second connecting pole 24 form a closed magnetic core, and magnetic circuit closure leakage field is few, inductance coefficent
It is higher, equivalent to anti-common mode, and reinforcing post 25 is provided between the first connecting pole 23 and the second connecting pole 24, in the reinforcing post 25
Separated to leave gap, referring specifically to Fig. 4, reinforcing post 25 includes upper reinforcing post 251 and lower reinforcing post 252, the upper He of reinforcing post 251
It is not connected among lower reinforcing post 252, leaves the reinforcing post 25 in space because the magnetic resistance of air is far longer than the magnetic resistance of magnetic core 2, because
This main magnetic circuit circuit is constant, and the magnetic circuit of reinforcing post 25 enhances magnetic field intensity so that and the inductance value of coil is increased, and significantly
Strengthen the stray field of two coils 3 so that respective electric leakage sensibility reciprocal increase, equivalent to adding a differential mode inductance, so that
The filter set of the invention function of common-mode filter and differential mode filter is obtained, and the coil 3 in the present invention is using flat
Horizontal line coiling, so as in same winding length compared to round wires equally around one layer when, greatly increase the number of turns, and suitable for adopting
With mechanization coiling, production efficiency is greatly improved, reduces cost.
It is first wrapping post 21, the second wrapping post 22, the first connecting pole 23, the second connecting pole 24, auxiliary in the present embodiment
Post 25 is helped to be structure as a whole, without increasing magnetic core element otherwise, more convenient during assembling, the skeleton 1 includes using
In the mounting groove 12 for positioning the magnetic core 2, the avoidance that the left side wall and right side wall of the mounting groove 12 are respectively equipped with hollow out is opened
Mouthfuls 13, due to the coiling of coil 3 on the first wrapping post 21 and the second wrapping post 22 after, volume is relative to become big, easily and mounting groove
Physical interference occurs for 12 left side wall and right side wall, therefore the left side wall and right side wall in the mounting groove 12 are respectively equipped with avoidance and opened
Mouth 13 facilitates subsequent installation.
Likewise, the bottom wall of the mounting groove 12, which is provided with, avoids groove 14, after magnetic core 2 is installed to mounting groove 12, only
First connecting pole 23 and the second connecting pole 24 are bonded with the bottom wall of mounting groove 12, and the other positions of mounting groove 12 have been coil
3 reserve space.
Mutually dismounted in order to facilitate magnetic core 2 and skeleton 1, the present embodiment magnetic core 2 with skeleton 1 is torn open using buckle structure
Dress, it is specially：The side wall of magnetic core 2 is provided with block button hole 26, and block button hole 26 is located at the first connecting pole 23 respectively in the present embodiment
In the side wall of the second connecting pole 24, the side wall of the mounting groove 12 is provided with and the buckle of the Matching installation of block button hole 26 projection
15, buckle projection 15 is located at the front side wall and rear wall of mounting groove 12, and during installation, magnetic core 2 is installed from top to bottom, buckle projection 15
Locking is realized in block button hole 26, wherein, the skeleton 1 is being provided with elastic groove 16 at buckle projection 15, designs bullet
Property groove 16 after, help to increase the deflection of buckle projection 15 so that more laborsaving, the present embodiment in installation or removal of magnetic core 2
Buckle projection 15 includes upper guiding surface and lower guiding surface, and being shaped as whole buckle projection 15 is trapezoidal, wherein on lead
Gradient to inclined-plane is different from the gradient of lower guiding surface, and the angle between the upper side wall of guiding surface and mounting groove 12 is led under being less than
Angle between inclined-plane and the side wall of mounting groove 12, this design advantage be, installation is more laborsaving, and needs when dismantling bigger
Power, prevent magnetic core 2 from deviating from skeleton 1 easily.
In the present embodiment, magnetic core 2 have also been made improvement in itself, wherein, the wrapping post 22 of the first wrapping post 21 and second
Cross sectional shape is ellipse, has so both considered the compressing of magnetic core 2, circular coil when taking full advantage of automated production again
3 inner space so that for coil 3 in coiling, compactness is more preferable, reduces rocking for coil 3, and the surface of the magnetic core 2 scribbles
Insulating barrier, the thickness that the insulating barrier especially on reinforcing post 25 applies is relatively large, to isolate two coils 3.
In order to increase radiating effect, heat emission hole, this reality are through between the bottom wall of the mounting groove 12 and the bottom surface of skeleton 1
Apply the heat emission hole in example and be spaced apart by the bar hole 17 of more than 2 and formed, bar hole 17 is distributed in two lines in the present embodiment
The correspondence of circle 3 issues, and is spaced apart, and because the coil 3 in the present embodiment is that flat wire coiling forms, this structure is adjacent
Gap is left between flat wire, the gap is just corresponding with the position of bar hole 17, can just strengthen cross-ventilation, radiating effect
Fruit is than more prominent.Certainly, it may occur to persons skilled in the art that, the shape of heat emission hole can change other shapes into.
The foregoing is only a specific embodiment of the invention, 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 is not limited to accompanying drawing and interior described in embodiment above
Hold, especially the shape and structure of block reinforcement.The modification of any function and structure principle without departing from the present invention is intended to be included in power
In the scope of sharp claim.
