A wire connector is a small device used to join two or more electrical wires together. It ensures a secure and reliable connection, allowing electricity to flow between the wires without interruption. Wire connectors come in various types, including twist-on, push-in, and solderless connectors, each designed for specific applications. These connectors are essential in many electrical projects, from household wiring to automotive applications. Proper use of wire connectors helps prevent electrical shorts and ensures safety in electrical systems. Common materials used for wire connectors include plastic and metal, which provide insulation and conductivity, respectively.
