The original shape of the 4mm banana plug is assembled by a base + an iron nail + a shrapnel, because the initial shrapnel is punched from a metal sheet into four leaf shapes. After it is assembled into the iron nail, it is inverted and peeled into four pieces. The banana is the same as the name "Banana Plug".



The 4mm banana plug has been gradually applied to industrial equipment, teaching equipment, power test radio models, medical equipment, automotive testing, audio equipment and other fields due to its excellent electrical performance, simple assembly method, and low-priced finished products. The type of banana plug has also been initially developed from the original simple four-leaf type.
