What Is a DC Connector?

In addition to meeting the general performance requirements of electrical connectors, a particularly important requirement is that the electrical connectors must achieve good contact, reliable work, and convenient maintenance. Whether their work is reliable or not directly affects the normal operation of the aircraft circuit, which involves the safety of the entire host.

Connectors are electromechanical components that connect electrical lines. Therefore, the electrical parameters of the connector itself are the first issues to consider when selecting a connector.

1. Development towards miniaturization, high density and high speed transmission;

2. Towards high-performance, high-frequency technology;

3. The market for high-voltage and high-current connectors is also large;

4. The connector is also developing in the direction of anti-interference technology, modular technology and lead-free technology.

In the case that the rate of traditional parallel synchronous digital signals is about to reach the limit, the high-speed serial method is a good solution. This makes Low Voltage Differential Signaling (LVDS) the primary level standard for next-generation high-speed signals. The choice of high-speed connectors has also become the main problem to be solved for high-speed signal interconnection.

Several key technologies used in the development of high-speed connectors include:

1. Differential signal, noiseless signal and ground layer technology used to reduce crosstalk;

2. In order to adjust the lead of the connector, the delay difference caused by the physical distance between the input and output of the connector can be changed;

3. In order to obtain the maximum transmission efficiency, the characteristic impedance value of the connector should match the characteristic impedance of the transmission circuit. ^[2]
