Description
Die Zeichnung veranschaulicht ein Ausführungebeispiel der im Sinn der Neuerung beschaffenden Spule. Fig. ist eine längsseitige Ansicht der in sich geschlossener Spule, Fig. 2 ein Querschnitt nach C-D der Fig. t Aus Fig*3 ist ersichtlich, wie die Zylindersegmente des Spu lenkernes usammengrèifen. The drawing illustrates an embodiment example of the in mind the innovation procuring coil. Fig. Is a longitudinal view of the inside closed coil, Fig. 2 is a cross section according to C-D of Fig. t From Fig. 3 it can be seen how the cylinder segments of the bobbin grip together.
Die Spule besteht aus zwei gleichen Teilen A, B. The coil consists of two equal parts A, B.
An der Stirnseite jedes Spulenteiles befindet sich eine Scheibe a bzw. b. Das Kernstück der Spule ist hohl und wird durch Zusammenschieben der beiden Teile A, B ßebildet. Zu diesem Zweck weist jede Spulenhälfte vier schme le, in gleichen Abständen angeordnete Zylindersegmente o bzw. d von gleicher Länge und Breite auf, die sich parallel zur Längsmittelachae der Spule erstrecken und von einem ringförmigen Formteil e bzw. f der Scheiben a bzw. b abstehen.At the end of each coil part there is a disk a or b. The core of the coil is hollow and is made by sliding the two together Parts A, B formed. For this purpose, each half of the spool has four rings of equal size Spaced cylinder segments o or d of the same length and width, which extend parallel to the longitudinal center axis of the coil and protrude from an annular shaped part e or f of the disks a and b.
Jedes Zylindersegment ist schmalseitig mit je eine : Nut m, n versehen, die, in der Längsrichtung des Segmentee verlaufend, dessen schmälere Innenfläche gegen die breitere Aussenfläche absetzt. Beim Zusammenstecken der Kernteile A, B wird jeweils ein Zylindersegment der eine Spulenhälfte in den Zwischenraum zweier Segmente der an deren Spulenhälfte geschoben, wobei Nut an Nut gleitet. Each cylinder segment is provided on the narrow side with one: groove m, n, which, running in the longitudinal direction of the segment, its narrower inner surface set off against the wider outer surface. When putting together the core parts A, B each one cylinder segment of one coil half is in the space between two Segments pushed onto the spool halves, sliding groove on groove.
Bei zusammengefügter Spule treffen die stumpfen Enden g der Segmente c der Spulenhälfte A auf den Ring f der Spulenhälfte B, die stumpfen Enden h der Segmente d auf den Ring e der Spulenhälfte A. Nunmhr bilden die Segmente c,d den hohlen, zylindrischen Kern der Spule.When the coil is assembled, the blunt ends g of the segments meet c of the coil half A on the ring f of the coil half B, the blunt ends of the h Segments d on the ring e of the bobbin half A. Now the segments c, d form the hollow, cylindrical core of the coil.
Wenn nun der aufgespulte Kunststoff-Faden schrumpf so drückt sich die erste Fadenlage in die durch die Seg mente c, d gebildete Umfangsfläche des Spulenkernes etwas ein und übernimmt die bei der Fadenschrumpfung auftretenden Scherkräfte, wodurch ein Auseinandergleiten der Segmente verhindert wird. Daher ist es nicht unbedingt nötigt dase die Segmente miteinander verklebt wer den. Vielmehr hält die Spule auch ohne Verklebung den auftretenden Spulungskräften stand. Ein Verkleben der Segmente ist nur erforderlich. um die leere Spule zusammenzuhalten. Der durch die Segmente gebildete Hohlkern hat sich als ungemein druckfest erwiesen. If the wound plastic thread shrinks, it is pushed the first thread layer in the circumferential surface of the formed by the Seg elements c, d Bobbin core and takes over the shear forces that occur when the thread shrinks, thereby preventing the segments from sliding apart. Hence it is not it is essential that the segments are glued together. Rather, it holds Spool withstood the occurring winding forces even without gluing. A sticking the Segments is only required. to hold the empty bobbin together. The hollow core formed by the segments has proven to be extremely pressure-resistant.
Die Spule kann aus Polystyrole einem Celluloseester, einem Polyamide Niederdruck-Polyäthylen oder einem sonst geeigneten Kunststoff gefertigt werden. The coil can be made of polystyrene, a cellulose ester, a polyamide Low-pressure polyethylene or any other suitable plastic can be manufactured.
Bei der Herstellung der Spule im Spritzgieaswege ist nur eine einzige Spritzform mötig. Ausser dem Verkleben der Zylindersegmente und dem Bohren der Scheibenlöcher i fallen keine weiteren Arbeitsgänge an. Daher kann die Spule verhältnismässig einfach und billig erzeugt werden. In the manufacture of the coil by injection molding there is only one Injection form possible. Except for gluing the cylinder segments and drilling the disk holes There are no further operations. Therefore, the coil can be relatively simple and produced cheaply.
