BOBBIN, TRIGGER COIL, MANUFACTURING METHOD THEREOF, FLASH UNIT AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To miniaturize a trigger coil by improving a bobbin.

SOLUTION: The bobbin is insert-molded using a resin which contains magnetic powder, in which a first metal body comprising a trigger output terminal and first and second winding terminals extending on the left and right sides of the terminal is arranged on a first spool side. The trigger output terminal and the first and second winding terminals are exposed by a part of them, respectively. A second metal body whose one end serves as an input terminal while the other end is a third winding terminal, and a third metal body whose one end is the other input terminal while the other end is a fourth winding terminal, are arranged on a second spool side. One and the other input terminals are exposed on the side opposite to the trigger output terminal by a part of them. A part of the third winding terminal is exposed on the same side as the first winding terminal. A part of the fourth winding terminal is exposed on the same side as the second winding terminal.
