High capacity electrical terminal connection

An electric terminal connection comprising:

• first and second electric terminals each having a through hole, the terminals being juxtaposed with the through holes thereof aligned;
• a bolt unit including a bolt head having a central insertion hole therethrough and a surface contacting one side of the first terminal, a shaft having a threaded first end extending through the through holes of said first and second terminals, and a second end extending through the insertion hole of said head, and a fixing bar disposed atop said head of the bolt unit and pivotally supported by said second end of the shaft of the bolt unit so as to be rotatable relative to said shaft about an axis extending perpendicular to the longitudinal axis of said shaft;
• and
• a nut threaded to said shaft of the bolt unit and having a surface contacting a side of the second terminal remote from said first terminal, and
• wherein said fixing bar has a bottom surface configured to exert a compressive force on said head of the bolt unit when said fixing bar is rotated about said axis from a first position to a second locking position.
