<p>PROBLEM TO BE SOLVED: To detect aslant tightened condition of a nut, when securing a terminal to the body part of a bolt terminal with the nut. SOLUTION: In this nut-tightening structure for terminal, a threaded body of the bolt terminal connected to a circuit stored in a block is protruded into the top wall of the block for storing electrical components, the threaded body is passed through an attaching hole in the terminal connected to an electric wire terminal, and the terminal and the head of the bolt are connected by tightening of the nut. A cover is attached to an electric wire, an outer periphery frame part which surrounds a nut-tightened section is extended, a lid part is jointed to one side of the outer periphery frame part via a hinge part so as to be opened/closed, and a rib for detecting a nut attachment posture is formed inside the lid part in a protruding manner. If the lid part is closed, under the condition with the threaded body and the electric wire terminal being tightened by the nut, the rib inside the lid part is brought into contact with the top surface of the nut at a regular tightening position, and the lid part is closed; while if the rib is brought into contact with the top surface of the aslant tightened nut, the lid part cannot be closed.</p> |
