<p><P>PROBLEM TO BE SOLVED: To connect and separate connecting terminals with and from each other without removing a bolt and a nut, and yet, achieve superb and firm connection. <P>SOLUTION: A protrusion 5b is provided at a peripheral edge of a screw hole of the nut 5, a first through-hole 2b for insertion of a bolt 4 is formed through the first connecting terminal 2, and a second through-hole 31 constituted of a large hole 31a, a small hole 31b and a communicating part 31c for the holes 31a and 31b is formed through a second connecting terminal 3. The large hole 31a is set at a size enough to have the nut 5 inserted into, the communicating part 31c is set at a size allowing insertion of the screw part 4a of the bolt 4 but not allowing insertion of the protrusion 5b of the nut 5, and the small hole 31b is set at a size enough to have the protrusion 5b of the nut 5 inserted but not allowing insertion of the nut 5. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
