Description
Technical field
This utility model belongs to communication technical field, specifically refers to a kind of wave filter, particularly relates to a kind of cavity body filter.
Background technology
Cavity body filter is widely used in the communications field as a kind of frequency selection device, especially field of radio frequency communication.In a base station, wave filter is used for selecting signal of communication, filters the clutter outside communication signal frequency or interference signal.Cavity body filter generally comprises low pass filter, typical low pass filter be a kind of make useful signal by and suppress the electronic installation of unwanted frequency signal simultaneously, in information processing, data transmission and suppression interference etc. automatically control, and communicate and are widely used in other electronic system.For realizing this function, it will usually a low pass of connecting in adapter one end realizes this function.
Cavity body filter of the prior art is generally adopted metal and makes cavity, and volume cannot be reduced by impact owing to being subject to frequency and electric property further, and owing to the density of metal is relatively big, thus cavity body filter volume and weight is big.And, the price of metal material is higher, and is also unfavorable for installing, dismantling and transport owing to the volume and weight of metal filter is all relatively big, causes production cost and maintenance cost all higher.The radiating effect of cavity body filter of the prior art needs to be improved further simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of cavity body filter.
This utility model is to be achieved through the following technical solutions:
A kind of cavity body filter, including cavity, in the inside of described cavity, processing has resonator cavity, in described resonator cavity, harmonic oscillator is installed, described harmonic oscillator includes medium body and is arranged on the outer surface of described medium body and/or the conductive layer of inner surface, and described cavity is rectangular structure, and all offers radiating groove A on the left and right side of cavity, two radiating groove A on left and right side constitute heat dissipation channel with resonator cavity, and the upper surface at described cavity offers radiating groove B；About described cavity, upper end, two sides is respectively arranged with multiple binding post, and runs through from top to bottom on described binding post and offer through hole, offers inserting groove on the side of described binding post；Described cavity is adopted made of plastic.
As optimal technical scheme of the present utility model, the bottom of described cavity is provided with installing plate, and offers installing hole on described installing plate.
As optimal technical scheme of the present utility model, described installing hole is U-shape structure.
Compared with prior art, the beneficial effects of the utility model are: this utility model adopts cavity made of plastic, it is possible to reduce the weight of cavity body filter；It is provided by radiating groove A and radiating groove B, two of which radiating groove A and constitutes heat dissipation channel with resonator cavity, it is possible to increase radiating effect, improve the service life of cavity body filter；It is provided by installing plate, it is simple to the installation of cavity body filter, dismounting and transport.
