Abstract

The invention provides an EMI filtering device. The device comprises a shell, a cover plate, a power supply filtering assembly, a signal filtering assembly and a clamping seat, the cover plate is detachably connected with the shell; the cover plate is used for sealing the shell to form a sealed cavity; the cavity is divided into a first mounting cavity, a second mounting cavity and a third mounting cavity through partition plates; a power supply filtering assembly is mounted in the first mounting cavity; a power input connector is installed on the side wall of the shell. The power supply inputconnector is used for inputting a power supply signal to the power supply filtering assembly. A signal filtering assembly is mounted in each second mounting cavity; at least one signal input interface is installed at the top of the shell. An output connector is installed on the side, deviating from the power input connector, of the shell, a clamping groove is further formed in the side wall of the shell, the clamping base is detachably connected with the clamping groove, a printed board rectangular connector is installed on the clamping base, and the problem that in the prior art, crosstalk coupling is prone to being formed between interference signals is solved.

Description

technical field [0001] The invention relates to the field of filtering, in particular to an EMI filtering device. Background technique [0002] When the current filtering device filters different signals, the problem of crosstalk coupling between interference signals is likely to be formed, which affects the filtering effect. Contents of the invention [0003] The present invention provides an EMI filtering device to solve the problem in the prior art that crosstalk coupling is easily formed between interference signals. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An EMI filtering device, comprising: a housing, a cover plate, a power filter assembly, a signal filter assembly, and a snap socket, the cover plate is detachably connected to the housing, the cover plate is used to close the housing and form a closed cavity, the The cavity is divided into a first installation cavity, a second installation cavit...
