Banana plugs are single-wire electrical connectors used for joining wires to equipment. In Europe, banana plugs are sometimes called 4 mm connectors, but not all bananas will connect with 4 mm parts. A Jack Banana is a cylindrical pin/plug that has sprung metal “leaves” that bulge outward, though variations on this exist for different applications. The springs produce a snug fit and good connectivity in a socket as well as preventing the pin from falling out. The diameter of the pin is usually 4 mm (which is why it’s also referred to as a 4 mm plug). The back of the pin is connected to a wire which is screwed, soldered or crimped into place. Often there is insulating plastic over part of the connector. These are used at the ends of patch cords for electronic test equipment, speaker wires and probe leads.
The original plug consists of a cylindrical metal pin about 20 mm (3⁄4 in) long. This pin length is still common in Europe and other parts of the world. However other sizes have emerged, such as 15 mm (5⁄8 in) pins, which can commonly be found in the US. Other lengths between 11 mm (3⁄8 in) and 25 mm (1 in) are less common.
For high voltage use, sheathed versions of the banana plug and socket are used. These add an insulating sheath around both the male and female connectors to avoid accidental contact. The sheathed male plug will not work with an unsheathed female socket, but an unsheathed male plug will fit a sheathed female socket.
