Translations:Twist-on wire connector/2/en

Twist-on wire connectors are commonly available and cheap way to make connections in circuits. They come in various sizes that are color coded but are only typically used for smaller circuits with wires that are 6 mm² (10 AWG) and smaller. They consist of a plastic body with a threaded spring inside. Two or more wires - solid or stranded - can be inserted into the connector and then it can be twisted, it will tighten around the wires and create a solid connection.
