The box-shaped insulating container 1 has an upper surface opening made of an electrically insulating material,
It has a slightly thick side wall, and a central partition plate 3 is integrally provided at the center of the inner bottom of the storage recess 2 at a height up to the opening surface. A pin terminal 4 having a round diameter and a holding portion 5 having a flat upper surface are integrally provided. The storage recess 2 has a depth capable of storing a coil element 6 to be described later, and the center partition plate 3 has a size that can be inserted into the center hole of the square core 7. Pin terminal 4
The upper end of the rod-shaped conductor is crushed flat, or the strip-shaped conductor is formed into a cylindrical shape from the middle to the lower part. A holding portion 5 comprising an insertion hole and an upwardly open slit extending from the upper end surface to the insertion hole is formed. Actually, the holding portion 5 has a diameter of the insertion hole substantially equal to or slightly larger than the diameter of the winding material, and the minimum width of the slit is set to a size slightly smaller than the diameter of the winding machine.

て巻回作業が容易である。The coil element 6 is a common mode choke in which windings 8 are wound around two opposing sides of a square core 7 coated with an insulating coating. Since the winding portion of the winding 8 is substantially straight and the core is wound through a central hole without a center partition plate, the winding operation is easier than in the case of a toroidal core.

線８の端部を狭持部５に導通接続できる。The coil element 6 is housed in the storage recess 2 of the box-shaped insulating container 1 by inserting the center partition plate 3 into the center hole of the core 7, and insulating resin (for example, silicone resin) 9 is provided on both sides of the center partition plate 3. Is filled almost completely and solidified to fix the coil element 6 to the insulating container 1 (see FIG. 1). Soldering is performed by passing the end of the winding 8 through the holding portion 5 integrated with the pin terminal 4, and a common mode choke coil is completed. Since the insulating film of the winding material is peeled off by heat at the time of soldering, the end of the winding 8 can be conductively connected to the holding portion 5 without a buckling operation.
