Banana Plug Male Blue

Description

Banana Plug Male Blue

Banana Plug Male Blue (commonly banana plug for the male, banana socket or banana jack for the female) is a single-wire (one conductor) electrical connector used for joining wires to equipment.

The term 4 mm connector is also used, especially in Europe, although not all banana connectors will mate with 4 mm parts, and 2mm banana connectors exist.

Various styles of banana plug contacts exist, all based on the concept of spring metal applying outward force into the unsprung cylindrical jack to produce a snug fit with good electrical conductivity.

Common types include: a solid pin split legthwise and splayed slightly, a tip of four leaf springs, a cylinder with a single leaf spring on one side, a bundle of stiff wire, a central pin surrounded by a multiply-slitted cylinder with a central bulge, or simple sheet spring metal rolled into a nearly complete cylinder.

The plugs are frequently used to terminate patch cords for electronic test equipment such as laboratory power supply units, while sheathed banana plugs are common on multimeter probe leads.
