Connectors

Connectors are electromechanical components designed to join and separate electrical circuits by providing a reliable interface between conductors, cables, or printed circuit boards. They enable modular system design by allowing interconnection without permanent bonding, supporting assembly, maintenance, and replacement.

In electronics, connectors typically consist of matched mating parts that establish electrical continuity and may also provide mechanical alignment and retention. Depending on the design, they can carry power, signals, or a combination of both, and may incorporate features intended to improve contact stability and reduce the risk of incorrect mating.

• Primary role: Create a detachable electrical interface between two circuit elements.
• Common elements: Contacts, insulating housing, and mechanical coupling features.
• Interconnection types: Board-level, wire-to-board, wire-to-wire, and panel interfaces.
