【発明の詳細な説明】
本発明は、中間周波トランス用高周波コイル装置等に用
いられるつぼ渥コアの改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a pot core used in a high frequency coil device for an intermediate frequency transformer.

く行かず。Conventionally, a coil device has been used in which a fill is housed in a space formed by a device core 211t provided with a central protrusion and connected to an electrode plate at the end of the coil. FIG. 5 shows a perspective view of a conventional device core. However, when trying to join together the vase cores shown in Figure 3, the joining did not go well.

が）、つた。A large amount of magnetic flux leaks from the abutting part, the shape of the abutting surface where the adhesive +J adheres is not uniform in the same direction, and the hot spring receives a shock, the abutting part breaks, or the core of the abutting part is damaged. It is difficult to put it together.

, 111 is glued. Due to the presence of the recesses 15, 115, alignment can be performed accurately and easily. In particular, when using an automatic bonding machine, the technical effects are significant. In addition, in the pre-firing molding of (a) having depressions 15 and 115, pressure was uniformly and sufficiently applied to the central protrusion, so the strength of the molded or fired product was also significantly increased.
