Abstract

The invention provides an EMI filtering device, comprising: a housing, a cover plate, a power filter assembly, a signal filter assembly and a clamping seat, the cover plate is detachably connected to the housing, and the cover plate is used to close the housing and form a closed A cavity, the cavity is divided into a first installation cavity, a second installation cavity and a third installation cavity by a partition, a power filter component is installed in the first installation cavity, and a power input connector is installed on the side wall of the housing, The power input connector is used to input the power signal to the power filter assembly, and a signal filter assembly is installed in each of the second installation cavities, and at least one signal input interface is installed on the top of the housing, and the housing is away from the power input connector. An output joint is installed on one side, and a card slot is also opened on the side wall of the shell. The card socket and the card slot are detachably connected, and a printed board rectangular connector is installed on the card socket, which solves the problem in the prior art. The problem of crosstalk coupling is easily formed between interfering signals.

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...
