Knowledge about banana plugs

A banana plug is a plug that is generally installed at both ends of the speaker wire and is inserted into a banana socket. The plug takes its name from its slightly bulging shape. It is very convenient to insert into the hole on the front of the multi-purpose socket mentioned above, and can also form a very large contact area after insertion. This feature makes it preferred for use in high power output equipment for connecting speakers and receiver/amplifiers.

Sometimes you can also see banana plugs divided into two groups, called "dual banana plugs", but not all equipment (especially speakers) can be used. Originated in Germany after the First World War, the original form was assembled by a base + an iron nail + a shrapnel. Since the original shrapnel was stamped into four leaf-like shapes from metal sheets, after it was assembled into the nails, it would be reversed. A banana peeled into four pieces is named "banana plug".

Due to its excellent electrical performance, simple assembly method, and low-cost finished products, banana plugs are gradually applied to industrial instruments, teaching instruments, power testing, radio models, medical instruments, automotive testing, audio equipment and other fields. The contact methods of banana plugs mainly include shrapnel type, pin type, cross groove type, and roll type.
