Abstract
The utility model relates to a filter applied to the field of electronic communication. The filter comprising a filter cavity (1) is characterized in that an upper resonance rod (2) is arranged on the upper surface inside the cavity (1), a lower resonance rod (3) is arranged on the lower surface inside the cavity (1), and the upper resonance rod (2) and the lower resonance rod (3) are in spaced arrangement. The filter realizes the aims of simple structure and convenient processing and debugging.
Description
Technical field
The utility model relates to a kind of filter that is applied to electronic communication field.
Background technology
Filter is mainly used in electrical communication system, is used for eliminating various interference, realizes doing the purpose of quality communication, be indispensable device in the electronic communication system, filter mainly comprises resonant cavity, and it is made up of a plurality of parts, and various piece needs processing respectively, assembles then.Its complex structure, processing is difficult for, and Installation and Debugging simultaneously are loaded down with trivial details, and assembly precision is uncontrollable.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and provide a kind of simple in structure, be convenient to the filter processing and debug.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of filter, comprise filter cavity, and upper surface is provided with resonant rod in described cavity, lower surface in cavity is provided with resonant rod down, and the described resonant rod of going up is spaced with following resonant rod.
Described upward resonant rod is an integral structure, and described resonant rod down is an integral structure.
Described cavity and last resonant rod and following resonant rod are integral structure.
Compared with prior art; last resonant rod and following resonant rod that the utility model filter comprises cavity and is arranged on interior upper surface of cavity and lower surface; and last resonant rod and following resonance are done at interval and arranged, and is simple in structure, simultaneously; last resonant rod adopts integral structure; following resonant rod adopts integral structure, has made things convenient for processing and installs, less debugging after installing; the precision height, and be convenient to large-scale production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, as shown in Figure 1, comprise filter cavity 1, upper surface is provided with resonant rod 2 in cavity 1, and the lower surface in cavity 1 is provided with resonant rod 3 down, and upward resonant rod 2 is spaced with following resonant rod 3.Last resonant rod 2 is an integral structure, and following resonant rod 3 is an integral structure, and last resonant rod and following resonant rod can adopt the casting one-shot forming, also can adopt the mode of machining to be processed into integral type.Improve greatly as of the present utility model one, can and go up resonant rod 2 with cavity 1, resonant rod 3 integral body make integral structure down, have not only reduced processing cost, also can reduce and install and the cost of debugging, be convenient to the production of scale more.
Claims (3)
1. filter, comprise filter cavity (1), it is characterized in that: upper surface is provided with resonant rod (2) in described cavity (1), and the lower surface in cavity (1) is provided with down resonant rod (3), and describedly goes up resonant rod (2) and following resonant rod (3) is spaced.
2. filter according to claim 1 is characterized in that: described upward resonant rod (2) is an integral structure, and described resonant rod (3) down is an integral structure.
3. filter according to claim 2 is characterized in that: described cavity (1) and last resonant rod (2) and following resonant rod (3) are integral structure.
