Multi-band bandpass filter

Abstract

The invention discloses a multi-band band pass filter, which comprises a housing. The top of the housing is movably connected with a shell cover. A connecting bolt penetrates through both sides of thehousing. A screw penetrates through both sides of the top of the shell cover. The top of the screw is fixedly connected with a rotary table. According to the invention, through the cooperation of thescrew, the rotary table, a rotating rod, a thread block, a first sliding pin, a transmission frame, a pin shaft, a second sliding pin, a transmission column, a sliding rod and a clamping rod, the clamping rod is separated from the interior of the clamping groove and the transmission column is separated from the interior of a fixed groove, an effect of rapidly disassemble the shell cover is achieved; the problem is solved that the shell cover and the housing of the existing band pass filter are bolted together, so when the filter fails and needs to be disassembled and repaired, only by using aspecial screwdriver, the filter can be opened, and the bolt will age for a long time, which causes a problem of the slippery phenomenon; the efficiency during maintenance is improved; and the practicability of the bandpass filter is enhanced.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a multi-band bandpass filter. Background technique [0002] Multiband is a technology that uses multiple frequency bands. The advantage of multi-band lies in its adaptability and scalability. The number of frequency bands can be different and can be dynamically adjusted to reduce the impact of mutual interference and avoid occupying the frequency bands required by other services. A bandpass filter is a device that allows certain frequency bands to pass while blocking other frequency bands. For example, the RLC oscillator circuit is an analog bandpass filter. [0003] The band-pass filter is a kind of electronic component, but the shell cover and the shell of the existing band-pass filter are connected together with bolts, and a specific screwdriver is required to open it when a fault occurs, and the bolts Long-term use will cause aging, which will lead to wire slipping, reduce...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-band band-pass filter, which has the advantage of being able to quickly disassemble the cover, and solves the problem that the cover and the housing of the existing band-pass filter are connected together by bolts. A specific screwdriver is required for fault disassembly and maintenance, and the bolts will age after long-term use, resulting in the problem of wire slipping
