Abstract

The invention relates to a filtering connector with an electromagnetic compatibility effect, belongs to the technical field of electromagnetic compatibility devices of space limited systems, and solves the problem that an existing shielding processing device cannot meet CE102 and RE102 index requirements of system-level electromagnetic compatibility. The filtering connector comprises a filtering connector body, a filtering assembly, a dustproof unit and a sealing unit, wherein the filtering assembly, the dustproof unit and the sealing unit are integrated on the filtering connector body. The filtering connector body comprises a shell, a mounting plate, a contact element assembly and a printed board, wherein the mounting plate is arranged in the shell, the printed board is arranged at the top end of one side of the shell, the contact element assembly is arranged on the mounting plate, the filtering assembly is arranged on a flange plate outside the shell, the contact element assembly isprovided with first to fourth point contact elements, and the filtering assembly is connected with the first to fourth point contact elements through the printed board and wires. According to the invention, the filtering assembly is integrated on the connector of a limited space system-level cable, so that the power supply filtering function is realized.

Description

Technical field [0001] The invention relates to the technical field of electromagnetic compatibility design for restricted systems, and in particular to a filter connector with electromagnetic compatibility. Background technique [0002] Space-constrained system refers to a system that has strict requirements on the spatial layout, volume, and interface of the components in the system under 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 interfaces of existing parts, and they also have strict requirements 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; however, due to the increase in system-level electromagnetic compatibility index requirements, the existing shielding treatment methods cannot meet the system...
