The invention discloses combined adjustable type composite filter cavity, including body and cover plate, body is rectangular box, cover plate matches somebody with somebody closing lid on body by the cover plate card article of body openings face both sides, body interior will be divided into multiple small cavitys by transverse dividing plate and longitudinal divider inside it, each small cavity surrounding is both provided with wire guide, body is provided at both ends with sub-assembly, multiple demarcation strip regulating tanks are provided with longitudinal divider, oriented corresponding mesh division board regulating tank is set on the inside of the body, is made using metal material.In use, when small cavity volume is inadequate, dividing plate can be removed, becomes large cavity, when number of cavities is inadequate, by assembly, assembling multiple cavities are used cooperatively, after cavity or the cavity of its combination so that multiple wave filters reduce influencing each other for signal into being arranged side by side.
Description
Technical field
The present invention relates to the filter cavity that experiment uses, and in particular to combined adjustable type composite filter cavity.
Background technology
Wave filter is the electronic equipment commonly used in hyundai electronicses electrical apparatus technology, with the development of electronic technology, to obtain essence
The higher signal of accuracy, the complexity more and more higher of its wave filter, many signals, which pass through more than, once to be filtered, in multiple filter
In the case of, it filters front and rear signal and is easily interfered, and when we are filtered device research and development, without filter cavity
Its multiple filter units are separated, the situation that signal easily interferes before and after each filter unit, influenceed
Experiment effect, therefore, to meet experimental development demand, it is necessary to which a kind of filter cavity that uses of experimental development is to facilitate wave filter
Exploitation.
The content of the invention
The technical problems to be solved by the invention are when being filtered device research and development, without multiple filters of the filter cavity to it
Ripple unit is separated, and the situation that signal easily interferes before and after each filter unit, influences experiment effect, purpose
It is to provide how compound experiment filter cavity, when solution is filtered device research and development, without filter cavity to the multiple of its
Filter unit is separated, and the situation that signal easily interferes before and after each filter unit, influences experiment effect
Problem.
The present invention is achieved through the following technical solutions：
Combined adjustable type composite filter cavity, including body and cover plate, body are rectangular box, cover plate
Closing lid is matched somebody with somebody on body by the cover plate card article of body openings face both sides；Body interior passes through transverse dividing plate and longitudinal subdivision
Plate will be divided into multiple small cavitys inside it；Each small cavity surrounding is both provided with wire guide；The body is provided at both ends with group
Component, the sub-assembly include assembly hook and the compoboard being engaged with assembly hook.To solve the problems, such as appeal, there is provided this hair
It is bright, a large cavity is formed by multiple small-sized cavitys, when in use, each filter unit uses a small cavity, filtering list
Wire between member by being connected between wire guide, be accustomed in use, being set according to wave filter, enter from a side opening, then from remote
Go out from wire guide corresponding to access aperture so that input between output away from farthest, reduce the interactional situation of signal, it is more
Individual small cavity also meets the characteristics of present wave filter is complicated, and filter unit is more, and after assembling a unit, its wave filter is carried out
Much time using laboratory, cavity is covered using cover plate, the parts of protecting filter each unit, is set by small cavity surrounding
The wire guide put, ventilation and heat can also be played a part of, when small cavity volume is inadequate, dividing plate can be removed, become large cavity,
When number of cavities is inadequate, by assembly, assembling multiple cavities are used cooperatively, after cavity or the cavity of its combination,
So that multiple wave filters into being arranged side by side, reduce influencing each other for signal.
Further, multiple demarcation strip regulating tanks are provided with longitudinal divider, it is oriented right to be set on the inside of the body
The mesh division board regulating tank answered.By setting regulating tank, the size of its small cavity can be adjusted, make the body of each small cavity
Product is more suitable for each filter unit, is adjusted as needed.
Further, cover plate, body, demarcation strip are all made using metal material.To make the letter between each filter unit
Number interference is smaller, uses metal material, isolates near-field interference.
The present invention compared with prior art, has the following advantages and advantages：
1st, the combined adjustable type composite filter cavity of the present invention, a large cavity is formed by multiple small-sized cavitys,
When in use, each filter unit uses a small cavity, the wire between filter unit by being connected between wire guide, make
Used time, set and be accustomed to according to wave filter, enter from a side opening, then go out from away from wire guide corresponding to access aperture so that input and defeated
Between going out away from farthest, reduce the interactional situation of signal, multiple small cavitys also meet that present wave filter is complicated, and filtering is single
The characteristics of member is more, after assembling a unit, much time using laboratory is carried out to its wave filter, chamber is covered using cover plate
Body, the parts of protecting filter each unit, the wire guide set by small cavity surrounding, the work of ventilation and heat can also be played
With when small cavity volume is inadequate, dividing plate can be removed, become large cavity, when number of cavities is inadequate, pass through assembly, assembling
Multiple cavities are used cooperatively, after cavity or the cavity of its combination so that multiple wave filters reduce signal into being arranged side by side
Influence each other；
2nd, the combined adjustable type composite filter cavity of the present invention, can be to its small cavity by setting regulating tank
Size is adjusted, and the volume of each small cavity is more suitable for each filter unit, is adjusted as needed；
3rd, the combined adjustable type composite filter cavity of the present invention, using metal material, near-field interference is isolated.
