Disclosed is a registered jack which is easy for a user to recognize, comprising: a registered jack main body connected to a cable, and an elastic sheet, wherein the elastic sheet extends from the registered jack main body; the elastic sheet is provided with an elastic sheet upper surface and an elastic sheet lower surface opposite each other; and an identifier mounting portion is arranged on the elastic sheet lower surface. Preferably, the identifier mounting portion is mounted on a lower surface of a pressing portion of the elastic sheet. The pressing portion may be of a transparent structure, thus making it easy for a user to recognize an identifier. The identifier is mounted on the identifier mounting portion, and the user may directly remove the identifier when the user needs to change the identifier of the registered jack, thereby being convenient for the user. In addition, the fact that the identifier is arranged on the lower surface of the pressing portion can protect the identifier from being worn out.
