Female (plug)

On the female plug, the outer body is metallic and cylindrical in shape, and comprises one of the two contacts. The second, inside contact is a hollow metallic cylinder constructed to accept insertion of the pin in the corresponding male connector. The inner and outer barrels are separated by an insulating layer. The outer contact is generally called the barrel, sleeve or ring, and the inner contact is called the tip.

Male (receptacle)

There is typically a single spring-loaded contact at the side of the male connector and a pin in the center corresponding to the intended female plug.
