Abstract

The invention relates to a filter connector with electromagnetic compatibility, which belongs to the technical field of electromagnetic compatibility devices for space-constrained systems, and solves the problem that existing shielding processing devices cannot meet the CE102 and RE102 index requirements of system-level electromagnetic compatibility. The filter connector of the present invention includes a filter connector body and a filter assembly integrated on the filter connector body, a dustproof unit and a sealing unit; the filter connector body includes a housing, a mounting plate, a contact assembly and a printed board; the mounting plate Set in the shell, the printed board is set on the top of one side of the shell, the contact component is set on the mounting plate, the filter component is set on the flange outside the shell, and the contact component is provided with the first point contact to the second For four-point contacts, the filter assembly is connected to the first to fourth point contacts through a printed board and wires. The invention integrates a filter assembly on the connector of the system-level cable in a limited space to realize the power filter function.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility design for constrained systems, in particular to a filter connector with electromagnetic compatibility. Background technique [0002] A space-constrained system refers to a system that has strict requirements on the spatial layout, volume, and interface of components in the system in a certain environment. This system generally exists in special equipment or precision instruments; such special equipment or precision instruments are not allowed to add new parts or change the interface of existing parts, and have strict restrictions on space layout and volume. [0003] At present, the electromagnetic compatibility design for space-constrained systems only exists in the shielding treatment of sensitive devices; and due to the improvement of the system-level electromagnetic compatibility index requirements, the existing shielding treatment methods cannot meet the system-level ele...
