In connector industry jargon, here are some key concepts:

Contact Resistance: The resistance of the current in a connector as it passes through the contacts, affecting the efficiency of signal transmission.

Insertion and extraction force: The force required to insert or remove a connector, critical to the user experience and the mechanical life of the connector.

Signal Integrity: The fidelity of a signal as it travels through a connector, including the amplitude, phase and frequency characteristics of the signal.

Differential Signal Transmission: A method of transmitting signals using pairs of wires that significantly improves the signal's immunity to interference.

Shielding Effectiveness: The ability of a connector to resist external electromagnetic interference, typically used for high-speed data transmission and RF applications.

Terminal Design: The design of the metal contacts inside the connector, which determines the electrical performance and connection stability of the connector.

Interconnect Density: The number of connection points a connector can provide in a given space, which is critical for miniaturisation and compact design.

These brands drive the connector industry through continuous technological innovation and product development, and meet the global market demand for high-performance connectors.
