  • Publication number: 20230420887
    Abstract: The disclosure provides a plug tab and a contactor and relates to technical field of electric power. The plug tab comprises: a body connected to a first conductive member; a plug-in part disposed on the body, the plug-in part is configured to be detachably connected to a first terminal; and an error preventing part disposed on the body, serves to interfere with plugging of a second terminal into the plug-in part; wherein the first terminal and the second terminal are different. The conduction between the first conductive member and the external current is realized by the plug-in part configured to be detachably connected to the first terminal. The error preventing part can interfere with plugging of the second terminal into the plug-in part by the arrangement of the error preventing part, such that the plug tab can only be corresponding to and matching with the first terminal.
