Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter with a protection function. Background Art

[0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out a specific frequency point in the power line or frequencies outside the frequency point to obtain a power signal with a specific frequency, or eliminate a power signal after a specific frequency. Filtering is an important concept in signal processing. The function of the filter circuit in a DC regulated power supply is to minimize the AC component in the pulsating DC voltage, retain its DC component, reduce the output voltage ripple factor, and make the waveform smoother.

[0003] The existing patent with publication number CN218734220U proposes a filter with a self-protection function. When the ammeter measures a large input current, the controller will automatically move the ammeter with a moving component to disconnect the output end of the ammeter from the conductive sheet 2, thereby avoiding damage to the filter body caused by excessive current. The top support component 1 and the top support component 2 cooperate with the conductive sheet 1 and the conductive sheet 3 respectively, so that the wires can be clamped, and the wiring ends of the two wires are respectively in contact with the conductive sheet 1 and the conductive sheet 3 to achieve electrical connection, thereby improving the wiring efficiency. However, the filter does not have the function of quick disassembly for maintenance. The current of the filter is prone to instability when in use, and short circuits are prone to cause damage to the filter. Existing filters are often fixed by bolts, and it is relatively difficult to disassemble them when they are repaired, which increases the burden on the staff, is time-consuming and labor-intensive, and is inconvenient to repair. In response to the above problems, we propose a filter with a protection function for improvement and upgrading. Utility Model Content
