PROBLEM TO BE SOLVED: To provide a trip lock terminal board capable of preventing entrance of foreign matters such as dust. SOLUTION: This trip lock terminal board is composed of a plug 8 formed by projecting a metallic current conducting plate 2 from an insulating support; and a body 9 for screwing two terminal screws for connecting a wire to an insulating block body. The plug is inserted into the body to electrically connect both terminal screws with the metallic current conducting plate, and the plug is drawn out of the body to electrically insulate the terminal screws. A projection 31 is projected in the periphery of a current conducting plate accepting hole 15 over the whole periphery, and a recess is formed in the central part of the plug surface of the insulating body of the plug.
