Abstract
The utility model discloses a built-in reed used for a tunable filter. The built-in reed comprises a beryllium bronze skin, wherein the beryllium bronze skin is wound to a columnar structure; two columnar beryllium bronze skins are respectively located at both ends; a plurality of reed racks are connected between the columnar beryllium bronze skins at both ends; a plurality of reed racks are encircled around the edge of the columnar beryllium bronze skin. The built-in reed used for the tunable filter is simple in structure and convenient to process and assemble, thus the good contact between the built-in reed and the resonate rod can be guaranteed while good electrical connection between a filter resonate rod and a cavity body is also guaranteed, thereby the electrical performance index of the tunable filter is greatly improved.
Description
Technical field
The utility model relates to the microwave communication equipment field, mainly is a kind of for the built-in reed on the tunable optic filter.
Background technology
The microwave tunable optic filter occupies very consequence in Modern Communication System, measuring system, but runs into a difficult problem manufacturing and designing the microwave tunable optic filter: the difficult problem of excellent electric contact between tuning plug and the cavity.
The utility model content
Technical problem to be solved in the utility model provides a kind of for the built-in reed on the tunable optic filter, it is simple in structure, process and assemble is convenient, can guarantee and the resonant rod good contact, guarantee simultaneously good being electrically connected between filter resonance bar and the cavity, greatly improved the electrical performance indexes of tunable filter.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of for the built-in reed on the tunable optic filter, include the beryllium-bronze skin, it is characterized in that: described beryllium-bronze skin is wound into column structure, the beryllium-bronze skin of described column structure has two and lay respectively at two ends, be connected with a plurality of reed tooth bars between the beryllium-bronze skin of two terminal circle rod structure, described a plurality of reed tooth bars are looped around edge one circle of the beryllium-bronze skin of column structure.
Tooth on the described reed tooth bar is semicircle curved toothing.
During practical set, beryllium-bronze skin and the filter cavity of column structure are welding as one, each curved tooth is tangent with the filter resonance bar on the reed tooth bar, can guarantee and the resonant rod good contact can effectively reduce and resonant rod between frictional resistance, also guarantee good being electrically connected between filter resonance bar and the cavity by the utility model simultaneously, greatly improved the electrical performance indexes of tunable filter.
The utility model has the advantages that:
It is simple in structure for the utility model, and process and assemble is convenient, can guarantee and the resonant rod good contact, has guaranteed simultaneously good being electrically connected between filter resonance bar and the cavity, greatly improves the electrical performance indexes of tunable filter.
