Modularization mixed filling filter connector

Abstract

The invention relates to a modularized mixed filter connector which comprises a plug and a socket. The mixed filter connector is characterized in that: the plug and socket of the connector are both provided with modules with radio frequency and wave filtering functions. The plug and a socket casing of the connector are both provided with chambers the number of which corresponds to the number of the modules with the functions. Every functional module is fixedly arranged in the corresponding chamber. The connector can transmit different signals simultaneously through different modules, has strong anti-interference performance, and meets the development trend of the requirements of equipment to electromagnetic compatibility. Besides, the connector is detachable, has the advantages of convenient assembly and maintenance and can meet the requirement of site replacement.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, in particular to a connector with shielding and filtering functions to prevent electromagnetic interference. Background technique [0002] With the increasing sensitivity of electronic equipment, especially modern military electronic equipment, the structure is more and more complex and precise, and various interference problems between electronic equipment are becoming more and more prominent, and the requirements of electromagnetic compatibility (EMC) are becoming more and more urgent. As far as a system is concerned, the electrical connector is used as an interface or channel for signal transmission. Electromagnetic interference (EMI) can not only conduct or radiate to the inside of the device through this window, but also conduct or radiate EMI to the outside of the device. These electromagnetic interferences are easy to cause Electronic equipment does not work properly, or dama...

Problems solved by technology

As far as a system is concerned, the electrical connector is used as an interface or channel for signal transmission. Electromagnetic interference (EMI) can not only conduct or radiate to the inside of the device through this window, but also conduct or radiate EMI to the outside of the device. These electromagnetic interferences are easy to cause Electronic equipment does not work properly, or damages sensitive electronic components

[0003] For the transmission of high-frequency signals, RF coaxial connectors are often used at present, and the equipment needs to use the same number of coaxial connectors to transmit several signals, so the installation process is more complicated, it is easy to cause wrong insertion, and the cost is higher

[0004] For the transmission of power and low-frequency signals, ordinary contacts are often used, but the electromagnetic compatibility performance often cannot meet the requirements, especially the power interface

Even if a shielding net is added to the connector housing, it only isolates all the contacts from the outside world, and the mutual interference between the contacts cannot be solved. At the same time, adding a shielding net not only increases the cost, but also increases the volume and weight of the connector. increase accordingly
