In a complex electromagnetic environment, the signal transmission performance of the connector is often affected by electromagnetic interference (EMI) factors, which leads to the failure of the signal transmission of the connector and the malfunction of the application equipment. Therefore, anti-EMI connectors are extremely important. Design points of anti-electromagnetic interference radio frequency connectors:
1. Material for connector housing. To resist electromagnetic interference, the material of the connector housing is very important. Why do RF connectors rarely use plastic shells? It is because the plastic case is transparent to electromagnetic interference. It will neither aggravate interference nor hinder electromagnetic interference. In the metal shell, any incoming or outgoing electromagnetic waves will induce current in the shell, causing energy to be lost from the waves. Therefore, it can play a shielding role.
2. Connector shielding layer design. The gap in the connector shell is often the weak point of EMI leakage to the connector. Because it will be equipped with a metal screen or cover to absorb electromagnetic interference transmitted through the air. The shield layer absorbs the transmission interference and directs it to the ground connection or virtual ground plane. The protected interference-free signal can reach the circuit, thereby maximizing the performance of the connector.
