Abstract

The invention discloses a filter with a fastened structure, and belongs to the technical field of filters. The filter comprises a circuit board, a coil is welded to the circuit board through a wire, abase is in threaded connection with the bottom of the circuit board, four groups of pins are distributed on the right side and the center of the lower surface of the base, grounding pins are welded to the left side of the lower surface of the base, electronic components are arranged on the upper surface of the circuit board, and a shell sleeves the circuit board; according to the invention, the electronic components are connected in parallel in the circuit through the circuit board; the component assembly is more beautiful; meanwhile, the positions of all the components can be distinguished more simply; unnecessary troubles caused by the fact that the filter is finally detected and repaired due to faults are avoided, through the structural design that the screw holes are formed in the grounding pins and the shell clamping pins are arranged, when the filter is connected with an electric appliance in an inserted mode, connection of the filter on the electric appliance is firmer throughcooperation of the screw holes and the screws and clamping of the shell clamping pins.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a filter with structural connection and fastening. Background technique [0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter the frequency point of a specific frequency in the power line or frequencies other than this frequency point to obtain a power signal of a specific frequency or eliminate a power signal of a specific frequency. Filtering is an important concept in signal processing. The function of the filter circuit in the DC stabilized power supply is to reduce the AC component in the pulsating DC voltage as much as possible, retain its DC component, reduce the ripple coefficient of the output voltage, and make the waveform become Relatively smooth. When the traditional filter is plugged into the electronic device, because the electronic device usually produces some vibrations when it is working, it is ...
