Adjustable composite filter cavity

Abstract

The invention discloses an adjustable composite filter cavity, which comprises a body and a cover board, wherein the body is a rectangular box; the cover board covers the surface of the body through coordination of cover board clamping strips at two sides of an opening of the body; the internal part of the body is divided into a plurality of small cavities through transverse division plates and longitudinal partition plates; wire guide holes are arranged in the periphery of each small cavity; a plurality of partition plate regulating tanks are arranged in each longitudinal partition plate; corresponding division plate regulating tanks are arranged in the inner side of the body; and the cover board, the body and the partition plates are made of a metal material. One small cavity is utilizedby each filter unit in use, and wires between the filter units are connected through corresponding wire guide holes, and are led in from the holes in one side and led out from the corresponding wireguide holes far away from the entering holes, so that the interaction effects of signals is reduced; and after various units are assembled, a laboratory is utilized by a filter for a long period of time and the cavity is covered with the cover board, so that the adjustable composite filter cavity can play ventilating and cooling roles through the wire guide holes in the peripheries of the small cavities.

Description

technical field [0001] The invention relates to a filter cavity used in experiments, in particular to an adjustable compound filter cavity. Background technique [0002] Filter is an electronic device commonly used in modern electronic and electrical technology. With the development of electronic technology, in order to obtain higher precision signals, the complexity of the filter is getting higher and higher. Many signals are filtered more than once. In the case of the filter, the signal before and after the filter is susceptible to interference, and when we are developing the filter, there is no filter cavity to separate its multiple filter units, and the signals are prone to mutual interference before and after each filter unit , affect the experimental effect, therefore, in order to meet the requirements of experimental development, a filter cavity used in experimental development is needed to facilitate the development of the filter.
