Banana jack / banana connector(commonly banana plug for the male, banana jack or banana socket for the female) is a single-wire (one conductor) electrical connector used for joining wires to equipment. The plugs are frequently used to terminate patch cords for electronic test equipment. They are also used as the plugs on the cables connecting the amplifier to the loudspeakers in a hi-fi sound system.

Banana jack / banana connector(commonly banana plug for the male, banana jack or banana socket for the female) is a single-wire (one conductor) electrical connector used for joining wires to equipment. The plugs are frequently used to terminate patch cords for electronic test equipment. They are also used as the plugs on the cables connecting the amplifier to the loudspeakers in a hi-fi sound system.

The plug was invented in 1924 by Richard Hirschmann (former Richard Hirschmann GmbH & Co.).

The plug consists of a cylindrical metal pin about 25 mm (one inch) long, with a diameter of 4 mm, which can be inserted into a matching 4 mm socket to make an electrical contact. The pin has one or more lengthwise springs that bulge outwards slightly. These press against the sides of the socket, improving the electrical contact and preventing the pin from falling out. The curved profile of these springs is probably the origin of the name "banana plug". The other end of the plug has a hole that accepts a length of flexible insulated equipment wire, which is either screwed, soldered, or crimped into place. An insulating plastic cover is usually fitted over this end.

The wide end of a 4 mm plug often has a 4 mm hole drilled in it, either transversely or axially, to accept the pin of another 4 mm plug. This type is called a stackable 4 mm plug.
