Title: Coil bobbin device
Inventor: MIYAGI KOICHI
IPC: H01F27/28
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent a so-called whisker of an end of a coil winding winded around a terminal pin and to improve solderability. SOLUTION: A groove 4a is made in a specified area of a terminal pin 4 to be press-fitted to a flange 1a of a coil bobbin. An end 3 of a coil winding is bound on the groove 4a. Since the end 3 can be cut by a corner of the groove 4a, a so-called whisker is not formed and a failure such as short-circuit can be prevented when the coil bobbin is mounted on a board. The area around which the end 3 is found is soldered and the end is connected to an outer circuit. In this case, the soldering is easy because the solderability is promoted by the groove. If the groove 4a is extended from the area around which the end 3 is found to the area to be press-fitted to the coil bobbin, the terminal pin 4 is also prevented from coming off.
