Abstract

PURPOSE:To reduce the assembling man-hour and the cost, by decreasing the number of components, through strong pressing of the tips of two core halves for stable fixing. CONSTITUTION:Ends 11a and 11b of tips of a core half 11 of semiarc shape are polished into the same plane. A core holder 12 made of nonmagnetic material such as brass is fitted at the back of the core half 11 and two arms 12 are projected from the side of the core holder 12 so that the core half 11 is held in. This is the same for a core half 16. A hole 15b passing through the end 11b of the core half 11 is made at the center of a bobbin 15a. After the lower end of the core half 11 is inserted to the hole 15b of the bobbin 15a and a spacer 18 is given to the end 11a, the lower end of the core half 16 is inserted to the hole 15b of the bobbin 15a. The end 11b of the core half 11 and the end 16b of the core half 16 are butted in the coil 15 and the end 11a and the end 16a are bonded via the spacer 18. Ends 12b and 17b of arms 12a and 17a are bonded with soft solder.
