[0002] The power filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency points of a specific frequency in the power line or frequencies other than this frequency point, obtain a power signal of a specific frequency, or eliminate a The power signal after a specific frequency, at present, there are still some shortcomings in the existing filter, for example; Disadvantages such as low suppression, and the existing filter housing and base plate have relatively low corrosion resistance and oxidation resistance, which reduces the service life of the filter

The invention discloses a band-pass filter and a method for manufacturing the band-pass filter. The band-pass filter structurally comprises a base plate, fixing holes, a cover plate, fixing screws anda sealing ring are arranged on the base plate, wherein the fixing holes are formed in the left side and the right side of the base plate, the cover plate is fixedly connected to the middle of the base plate, the fixing screws are fixedly connected to the four corners of the cover plate, the sealing ring is fixedly connected to the junction of the base plate and the cover plate, the upper end of the base plate is fixedly connected with a shell, and a fixing column and a threaded joint are arranged on the shell, and the fixing column is fixedly connected to the middle of the left end and the right end of the shell. The band-pass filter is small in size, high in reliability is high, stable and reliable in the performance in the full-temperature range, flat in the in-band amplitude-frequencycharacteristic, low in insertion loss, high in out-of-band inhibition degree, narrow in transition frequency band and the like. Since an electroplating method is adopted, the corrosion resistance andthe oxidation resistance of the shell and the base plate can be effectively enhanced, and the service life of the filter is prolonged.
Description
technical field [0001] The invention relates to the technical field of electronic components, in particular to a band-pass filter and a method for manufacturing the band-pass filter. Background technique [0002] The power filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency points of a specific frequency in the power line or frequencies other than this frequency point, obtain a power signal of a specific frequency, or eliminate a The power signal after a specific frequency, at present, there are still some shortcomings in the existing filter, for example; The disadvantages are low suppression degree, and the corrosion resistance and oxidation resistance of the existing filter shell and base plate are relatively low, which reduces the service life of the filter. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art...
