The utility model provides a connecting terminal is moved back in throwing of electric power system relay protection pull -plug type clamp plate, including the body, cavity, first and second inlet wire end, the first and second leading -out terminal of activity head in the middle of the body is equipped with and is used for holding, reserve the activity distance that has the first end of middle activity between first, second inlet wire is held, the two equal accessible wire links to each other with the power common port, first leading -out terminal and first inlet wire end is relative to be set up, and the second leading -out terminal is relative with second inlet wire end to be set up, reserve between the two have in the middle of the activity distance of the first other end of activity, and link to each other with identification equipment both ends respectively through the wire, when activity head motion to both ends linked to each other with first inlet wire end and first leading -out terminal respectively in the middle of treating, export clamp plate state was for throwing, when activity head motion to both ends linked to each other with second inlet wire end and second leading -out terminal respectively in the middle of treating, export clamp plate state was for moving back. Implement the utility model discloses, can discern the throwing of export clamp plate that has the middle activity head of electric conductivity moves back.
