Connectors are key components for establishing secure electrical connections, featuring reliable contact, easy mating/unmating, and vibration resistance. They are typically made of conductive materials like brass, phosphor bronze, or beryllium copper (often gold- or tin-plated), with insulating housings of engineered plastics (PBT, nylon) or thermoset materials. Widely used in automotive electronics, industrial equipment, consumer devices, aerospace systems, and renewable energy installations, connectors facilitate power transmission, signal transfer, and modular assembly across various electrical and electronic applications.
