[Problems to be solved by the device]

 Conventionally, this type of drum core coil with a base has a drawback that it takes a lot of time for bonding time and drying time because the drum core and the base are bonded. In order to eliminate these drawbacks, the present invention eliminates these drawbacks by inserting a lower brim insertion hole into which the lower brim of the drum core is fitted on the side surface of the base, and a U-shaped reel insertion groove at the back of the reel insertion slot into which the reel of the drum core is inserted. In order to fix the drum core and the base by inserting the drum core into the lower core, especially by fitting the lower flange of the drum core into the lower flange insertion hole, and by winding the winding of the drum core to the connecting terminal. The object is to provide a drum core coil with a base that does not use an adhesive by reducing the number of bonding steps.

[0004]

[Means for Solving the Problems]

 The present invention relates to a drum core coil with a base in which a drum core is incorporated in a base having a recess for bonding and fixing a mounting electrode, a connecting terminal, and a lower flange of the drum core, and which faces a connecting terminal on one side surface of a box-shaped base. A lower flange insertion hole for inserting the lower flange of the drum core into which the drum core winding frame is inserted with one surface as an open end, a winding frame insertion opening for inserting the drum core winding frame, and a U-shaped winding frame. A drum core coil with a base characterized by having an insertion groove.

[0005]

[Action]

 According to the present invention, a lower flange insertion hole for fitting a lower flange of a drum core from a side having an open end facing one side of a side surface of a side surface of a box-shaped base of a drum core coil with a base, and a drum core winding. Insert the drum core into the winding frame insertion slot for inserting the frame and the U-shaped winding frame insertion groove, and by winding the drum core with the drum core inserted as far as it will go, fix the lower brim insertion hole or the drum core and the base. It is a constructed base, and the bonding process can be omitted.

【Example】

 FIG. 1 is an exploded perspective view of a drum core coil with a base according to the present invention. FIG. 2 is an assembled perspective view of a drum core coil with a base according to the present invention.

As shown in FIG. 1, the drum core coil with a base of the present invention includes a drum core a having an upper collar k, a bobbin h, and a lower collar L, which is incorporated in a base d, and is wound with a winding c. The drum core coil with a base shown in FIG. 2 is manufactured. The base d has a box shape. The base d has a connecting terminal f and a mounting electrode e. Further, the lower flange L of the drum core a is fitted from the open end with the surface facing the side surface projecting the two connection terminals f of the base d 1, that is, the surface orthogonal to the surface having the mounting electrode e as the open end. A mating lower brim insertion hole i is provided. The lower brim insertion hole i serves not only to fit the lower brim L of the drum core a, but also to fix the drum core according to the thickness of the lower brim of the drum core. The lower brim insertion hole i may have a rounded tip or a square tip so as to fit the lower brim of the drum core. Further, in order to insert the lower brim of the drum core and the reel h of the drum core, the reel insertion port m is required. The reel insertion port m is slightly larger than the reel h of the drum core and is a straight insertion port. The U-shaped winding frame insertion groove j in which the winding frame h of the drum core is fixed and positioned has a semicircular shape so as to match the cylindrical shape of the winding frame. A drum core coil with a base formed by fitting the lower flange L of the drum core a through the lower flange insertion hole i, incorporating the drum core into the U-shaped winding frame insertion groove j through the winding frame insertion port m, and providing the winding c. is there.

FIG. 2 is a completed view of the drum core coil with a base. The drum core a has a surface facing the side surface projecting the two connection terminals f as an open end, and the lower flange L of the drum core a is inserted into the open end. There is a lower brim insertion hole i so that the lower brim L of the drum core a can be mounted, and the lower brim of the drum core is fitted into the lower brim insertion hole i. At the same time, there is a straight reel insertion port m so that the reel h of the drum core a can be inserted deeply, and the U-shaped reel insertion groove j for positioning the drum core a serves as a stopper, so that the drum core Is attached to the base, winding is performed, the ends of the winding are twisted to the connecting terminals, and the drum core coil with base is completed.

According to the present invention, the lower flange of the drum core is fitted in the U-shaped winding frame insertion groove on the side surface of the base, and the winding is performed while being pushed inward, and the base and the core are fixed by the winding. It is also possible to
