PURPOSE:To provide a connection not requiring further tightening for a long time thereby decreasing occurrence of troubles at the connection, by pressing the terminal and a connecting plate into an integral body by the use of a die and a terminal protecting metal frame. CONSTITUTION:A connecting plate 2 made of copper is held to abut on one surface of the terminal 1 made of lead and a washer 3 is held to abut on the other side of the same, a die 6 is held so that a ring-shaped protrusion on the same abuts on the connecting plate 2, a terminal protecting frame 9 is put on the above mentioned members, and a bolt 4 and a nut 5 are tightened with each other with a torque wrench so that the terminal 1 and the connecting plate 2 are pressed together and becomes an integral body, and thereafter the terminal protecting plate 9 is removed and the connection is thereby completed. By making the connection in the above described way, the plastic deformation sideways of the terminal 1 during the application of the pressure for the connection is blocked by the terminal protecting metal frame 9, that is, the compressive stress does not escape to anywhere, and therefore, an easy and complete connection by pressure between the terminal 1 and the connecting plate 2 can thus be provided. |
