Wire connectors and terminals make the joint itself: they hold the conductors together mechanically and insulate the connection electrically. Closed end connectors use a nylon crimp cap over a tin-plated aluminium sleeve; the cap insulates and protects the splice while the sleeve is crimped onto the twisted conductors, giving a connection that resists corrosion and does not rely on tape. Wire nuts achieve the same result by threading onto the twisted conductors and gripping them under spring tension, which suits fast assembly in junction boxes and luminaire wiring.
Both are specified where a splice has to be permanent and inspection-free: panel and appliance wiring, lighting circuits, junction boxes and general electrical assembly.
Wandu produces these connectors as part of a wider wiring accessories range that also covers cable ties, clips, glands and cable protection, so a single order can cover a full BOM. The company has held ISO 9001, CE (LVD) and RoHS certification since its wiring range was extended, offers OEM/ODM on size, colour and packaging, and quotes 3–15 days for delivery after order and payment confirmation.
