Abstract

The invention provides a multifunctional communication signal filter. The multifunctional communication signal filter comprises an upper cover plate, a shell, a filter body, a damping block, an inputend line bank, an input end binding post, an input line pressing screw, an output end line bank, an output end binding post, an output line pressing screw and a copper core cable. A side folded plate,a movable bolt and nut, a U-shaped mounting base, an adjusting plate, a hollow dustproof plate and a wing-shaped screw are arranged, a good dustproof protection effect on the filter body is achieved.Through loosening wing-shaped screw, the telescopic position of the adjusting plate in the hollow dustproof plate can be pulled outwards. After the position is determined, the wing-shaped screw can be locked, the dustproof effect is guaranteed, the bending position of the side folding plate in the U-shaped mounting base through the movable bolt and nut can be adjusted by loosening the movable bolt and nut, the side protection effect is guaranteed, and finally the movable bolt and nut are locked, so that the dustproof protection effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of filters, in particular to a multifunctional communication signal filter. Background technique [0002] The communication signal filter is used to filter out the useful signal from the input signal and filter out the unwanted signal and noise interference. The principle is to use the amplitude-frequency characteristics of the circuit, set the range of its passband to the range of useful signals, and filter out other spectral components. [0003] At present, in order to ensure the stability of communication signals, information processing is performed through filters. [0004] However, the existing communication signal filter still has the problems of poor heat dissipation effect, affecting the filtering effect when vibration occurs after installation, lack of dustproof function and inability to adjust the installation position. [0005] Therefore, it is very necessary to invent a multifunctional communic...
