Abstract
The utility model discloses a kind of filter cavity of maskable noise signal, it comprises: cover plate, cavity, radiator, shielding box, resonatron, division board, barrier shield, receiver, described cavity is located on cover plate, the inside of cavity is all located at by described radiator, described shielding box and described receiver, described resonatron and described division board are all located at the inside of shielding box, and described barrier shield is located on shielding box.Radiator described in the utility model, it can distribute the heat that whole filter cavity produces timely fast, and carries out secondary heat radiation by hollow out shape metallic heat radiating plate; The application of barrier shield simultaneously, the frequency that receiver can be received carries out filtering first, and then by the resonatron array in shielding box, carries out maximization interference signal and noise signal shielding, and then realize double medium filtration, allow it reach the most perfect filter effect.
Description
Technical field
The utility model relates to a kind of frequency filter, specifically a kind of filter cavity of maskable noise signal.
Background technology
Along with socioeconomic development, the requirement of people to live and work is more and more higher, is also like this in daily communication system, in characteristic frequency receiving course, often occurs interference signal or noise signal.At present existing cavity body filter generally adopts the precious metal such as aluminium, copper to make on the market, its not only, be unfavorable for installing, dismounting and transporting, and due to the price of precious metal higher, cause the production cost of filter cavity higher.
Thus adopt plastic material to make filter cavity and will become main flow, although itself but plastic material have, material is light, low cost and other advantages, but its heat-conductive characteristic is poorer than metal, in filter cavity use procedure, the heat accumulating in plastic chamber inside can not distribute in time, local temperature can be caused more and more higher and cavity body filter allomeric function was lost efficacy; Especially for high power filter, more heat transfer can be gathered at short notice in plastic chamber inside, can not distribute in time, the electricity function index of cavity body filter is caused to decline, even there is strike phenomenon, thus it can not meet the demand of work, the needs meeting user that can not be real, therefore the production technology of filter cavity needs to improve further.
Utility model content
Utility model object: the purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of filter cavity of maskable noise signal.
Technical scheme: in order to realize above object, the filter cavity of maskable noise signal described in the utility model, it comprises: cover plate and cavity, described cavity comprises radiator, shielding box, resonatron, division board, barrier shield and receiver, described cavity is located on cover plate, the inside of cavity is all located at by described radiator, shielding box and receiver, and described resonatron and division board are located at the inside of shielding box, and described barrier shield is located on shielding box.Barrier shield and radiator is added in the utility model, the frequency that receiver can receive by described barrier shield carries out filtering first, and then carry out filtration shielding by whole cavity, and then realize double medium filtration, it is allowed to reach more perfect effect, the heat produced in resonatron running will be dissipated with prestissimo by metal heat-conducting original paper by described radiator, and then improve the speed of service of whole filter cavity.
Resonatron described in the utility model and described division board are all located at the inside of shielding box, and resonatron is separated according to certain quantity by described division board, and arranges from high to low, realize filtering layer by layer, make required characteristic frequency clearer.
The openend of the resonatron described in the utility model is connected with radiator by metal heat-conducting original paper, carries out loose defeated, realize quick heat radiating to heat.
Barrier shield described in the utility model and described shielding box match, and connect into seal box body, realize double layer screen by screw, filter out interference signal or noise signal to greatest extent, realize signal frequency bilayer purifying, and then reach perfect effect.
Cover plate described in the utility model is hollow out shape metallic heat radiating plate, and secondary dispels the heat, and allows whole filter cavity reach and realizes better radiating effect.
Beneficial effect: the filter cavity of maskable noise signal described in the utility model, has the following advantages:
1, radiator described in the utility model, it can distribute the heat that whole filter cavity produces timely fast, and carries out secondary heat radiation by hollow out shape metallic heat radiating plate, and then allows whole filter cavity reach better radiating effect.
2, the frequency that receiver can receive by barrier shield described in the utility model carries out filtering first, and then by the resonatron array in shielding box, carry out maximization interference signal and noise signal shielding, and then realize double medium filtration, allow it reach the most perfect filter effect.
