Description

Combined filter Technical Field The utility model belongs to the technical field of filters, and particularly relates to a combined filter. Background The filter is a filter circuit composed of a capacitor, an inductor and a resistor, and can effectively filter the frequency point of the specific frequency or the frequency outside the frequency point in the power line to obtain a power signal of the specific frequency or eliminate the power signal of the specific frequency. For example, chinese patent with publication number CN219458673U discloses a combined passive filter, which comprises a housing, the side wall of the housing is fixedly provided with a mounting seat, the inner wall of the housing is fixedly provided with a single tuning filter circuit box, the output end of the single tuning filter circuit box is electrically connected with a high-pass filter circuit box through a circuit switch, and the top of the housing is fixedly provided with a connector. This combination formula passive filter, in order to avoid the circuit when being connected, the copper wire of electric wire receives to pull and appear wearing and tearing or the condition that drops when contacting with the connector, through being provided with skid-proof assembly, the cooperation can be along with insulating bolt downwardly located and pivoted bull stick to make the volute spring drive the connecting rod and press from both sides tightly each other, thereby make the copper wire of locating plate chucking electric wire in the position of front and back both sides, thereby strengthen the location effect of electric wire copper wire greatly, guarantee circuit connection's stability. The above patent has the following problems: The single-tuned filter circuit box and the high-pass filter circuit box of the device need to be fixed in the shell by using tools, and are inconvenient to overhaul when the tools are not used. In view of this, we propose a combined filter. Disclosure of utility model The present utility model is directed to a combined filter for solving the above-mentioned problems.
