Description

Technical Field

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

[0002] The function of a filter is to allow signals of a certain frequency range to pass smoothly, while signals of other frequencies are greatly suppressed. It is essentially a frequency-selective circuit. In a filter, the frequency range that signals can pass is called the passband; conversely, the frequency range where signals are greatly attenuated or completely suppressed is called the blockband. The dividing frequency between the passband and the stopband is called the cutoff frequency. The voltage gain of an ideal filter is constant within the passband and zero within the stopband. In actual filters, there is a transition band between the passband and the stopband within a certain frequency range.

[0003] A search revealed a utility model patent with Chinese patent publication number CN203840294U, which discloses a network filter and a packaging housing. This utility model discloses a network filter comprising a substrate, a filter assembly disposed thereon, pins disposed on both sides of the substrate, both pins connected to the filter assembly, a housing disposed above the substrate, and at least one exhaust groove disposed on the bottom surface of the substrate. This utility model provides exhaust grooves on the bottom surface of the substrate, effectively venting the product when it is packaged, reducing the risk of the product being subjected to excessive stress and causing it to burst. Furthermore, this reduces material consumption and thus production costs.

[0004] The above patents have been searched and found to have processed the exhaust gas of the network filter package. However, the device is not convenient for layered assembly and processing of the network filter, which results in complicated and tedious operations during the assembly and processing of the network filter.
