Description
Technical field
The present invention relates to electronic technology, more particularly to wave filter.
Background technology
Compact filter is widely used on various household electrical appliance and electronic device, because miniaturization and lightening development become
Gesture, therefore at present, the developing direction of wave filter is good product consistency, and size is small easy to install.But volume diminishes can influence it
Inductance value.
The content of the invention
The technical problems to be solved by the invention are just to provide a kind of compact filter, in the case of size is conditional,
Accomplish the inductance value of maximum with minimum size as far as possible.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：A kind of compact filter, including wave filter bone
Frame and the magnetic core being installed on wave filter skeleton, the magnetic core are provided with two and including first panel and located at first panel side
The second panel in face, the first panel and be square/rectangle and L-shaped, the first panel after combining with first panel
Middle part is vertically provided with center pillar, and the wave filter skeleton is provided with the through hole of front and rear insertion along axis, before the wave filter skeleton
Two ends are provided with end plate afterwards, and the wave filter skeleton is provided with least one piece dividing plate along the longitudinal direction, between adjacent two dividing plate and every
Separation trough is formed between plate and end plate, the bottom of the end plate is provided with pin support, and the pin support is provided with pin, two
In in the front and rear both sides of wave filter skeleton, the center pillar insertion through hole, the center pillar and through hole are circle to magnetic core abutting joint,
The end plate and dividing plate are square/rectangle.
Preferably, the back side of the first panel and second panel is provided with groove along its length, and the wave filter is also wrapped
The housing that magnetic core is coated and fixed on wave filter skeleton is included, the housing is provided with the boss being fastened in groove.
Preferably, the top left and right sides of the end plate is provided with hanging wire pin.
The technical solution adopted by the present invention, magnetic core center pillar is circle, compared to square or other shapes center pillars, in circle
The magnet coil that the magnetic core of post has magnetic conductivity higher, same number of turns can do inductance value higher, and equal inductance is reached in other words
Amount can reduce the number of turns, reduce copper cash consumption and carry out reduces cost, and reduce volume.In addition, magnetic core both sides panel is all square, so that
Increase by two stability of magnetic core, it is more steady when magnetic core is docked.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation one of wave filter skeleton；
Fig. 2 is the structural representation two of wave filter skeleton；
Fig. 3 is the structural representation of magnetic core..
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of compact filter, including wave filter skeleton 1 and the magnetic being installed on wave filter skeleton
Core 2.
Wherein, as depicted in figs. 1 and 2, the wave filter skeleton 1 is provided with the through hole 10 of front and rear insertion along axis, described
The rear and front end of wave filter skeleton is provided with end plate 11, and the wave filter skeleton is provided with least one piece dividing plate 12, phase along the longitudinal direction
Separation trough 13 is formed between adjacent two dividing plates and between dividing plate and end plate, the bottom of the end plate is provided with pin support 111, pin
Support is rectangular, and the pin support is provided with pin, and two abutting joints of magnetic core 2 are in the front and rear both sides of wave filter skeleton.Draw
The middle part bottom surface of foot support is provided with hanging wire boss 113, and the corresponding both sides of hanging wire boss 113 of pin support 111 are provided with separated time groove 114.
As shown in figure 3, the magnetic core 2 is provided with two and includes first panel 21 and located at first panel side second
Panel 22, the first panel and be square/rectangle and L-shaped after combining with first panel, and the first panel middle part is hung down
Straight to be provided with center pillar 23, in the center pillar insertion through hole, the center pillar and through hole are circle.Compared to square or other shapes
Center pillar, the magnet coil that the magnetic core of circular center pillar has magnetic conductivity higher, same number of turns can do inductance value higher, reach in other words
The number of turns can be reduced to equal inductance value, is reduced copper cash consumption and is carried out reduces cost, and reduce volume.Further, center pillar correspondence the
One face plate edge is provided with flush tangential section.
/ the rectangle in addition, the end plate 11 and dividing plate 12 are square.To increase by two stability of magnetic core, in magnetic core pair
It is more steady when connecing.The top left and right sides of end plate is provided with hanging wire pin 112, to facilitate hanging wire.
The back side of the first panel 21 and second panel 22 is provided with groove along its length, and the wave filter also includes will
Magnetic core is coated and fixed the housing on wave filter skeleton, and the housing is provided with the boss being fastened in groove.The common magnetic core back side
Smooth, the recessing of the magnetic core back side solves common UTF magnetic cores and is unfavorable for fixed shortcoming, only need to be in magnetic core group when production
Dress one housing of rear enclosure can just be completely fixed magnetic core, and housing is not easy to rock.
The present invention can greatly promote the service efficiency of magnetic core, in equal space by the selection and improvement to magnetic core
In the case of, rationally increase the size of magnetic core, so that product is more stablized.Designing groove simultaneously can also lift producer in assembling magnetic
Production efficiency during core, can increase magnetic core stability after assembling again, moreover it is possible to prevent magnetic core because of inclination and caused by inductance value it is low
The problems such as, while can also reduce man-hour of the product in production using housing, reducing the cost of product, more conducively product is pushed away
Extensively with utilization.
