Terminal connection structure

A terminal connection structure in which a stud bolt is inserted into a bolt insertion hole of a top plate portion of a terminal, and a nut is screwed and fastened to the stud bolt on the top plate for connecting the terminal to the stud bolt, the structure comprising:

• a terminal accommodation section formed by a tubular protection wall extended upwardly from the top plate of the terminal and around the stud bolt, having an opening and ribs formed on of a circumference thereof, the terminal accommodation section allowing the top plate portion of the terminal fixed to an end of a wire to be inserted in the tubular protection wall on the stud bolt,
• wherein the opening is formed so as to fit on a belt portion extending from a part of an outer peripheral edge of the top plate portion of the terminal toward a fixing portion of the terminal,
• wherein the ribs are protruded on right and left sides on an interior of the protection wall with respect to the opening, the ribs coming into contact with right and left side edges of the belt portion of the terminal and preventing the terminal from being detached upward when the terminal is temporarily lifted,
• wherein the ribs are arranged at different heights in a top-bottom direction of the stud bolt, and
• wherein the ribs respectively have guide slope surfaces in upper surfaces thereof, the guide slope surfaces sloping downward from a base side of the ribs toward a tip side of the ribs to facilitate the insertion of the terminal when the terminal to be inserted into the terminal accommodation section comes into contact with the ribs.
