Description
Es sind Sprechköpfe für Magnetogrammträger bekannt, worin zwei das Magnetsystem enthaltende und zwischen sich den Magneto grammträger hindurchlassende Teile an einem für die stromleitende Verbindung eingerichteten Tragkörper zum Freilegen des Magnetogrammträgers ausschwenkbar sind, wobei die Polkerne der Teile längs beweglich sind und mit einstellbarem Federdruck gegen den Magnetogrammträger gepreßt werden.There are speech heads for magnetogram carriers are known, wherein two the magnet system containing and between them the Magneto gram carrier passing parts on one Carrying body set up for the conductive connection to expose the magnetogram carrier Can be swiveled out, the pole cores of the parts being movable lengthways and with adjustable spring pressure against the Magnetogram carriers are pressed.
Es ist von wesentlicher Bedeutung, daß die Polkerne von Druck entlastet sind, während die beiden Teile des Sprechkopfes ausgeschwenkt und zusammengeschlossen werden, und der Zweck der vorliegenden Erfindung ist, eine Anordnung zu treffen, wodurch die Polkerne zeitweilig von dem Druck der sie belastenden Feder befreit werden können, ohne ihre normale Einstellung in bezug auf den Magnetogrammträger zu verändern.It is essential that the pole cores are relieved of pressure while the two parts of the speaking head are swung out and locked together, and the purpose of the present invention is to make an arrangement whereby the pole cores temporarily from the pressure of them onerous spring can be released without relating to their normal setting to change the magnetogram carrier.
Gemäß der Erfindung wird dieser Zweck dadurch erreicht, daß die Federbelastung der Polkerne mittels eines unter Federdruck stehenden Gleitstempels herbeigeführt wird, der von außen zur Entlastung der Polkerne von Druck zurückgezogen und in der zurückgezogenen Stellung festgelegt werden kann.According to the invention this purpose is achieved in that the spring loading the pole cores are brought about by means of a slide stamp under spring pressure, which is withdrawn from the outside to relieve the pole cores of pressure and in the withdrawn Position can be set.
Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, wobei ein Teil des Sprechkopfes im Schnitt veranschaulicht ist.In the drawing, the subject matter of the invention is shown, for example, wherein part of the headset is illustrated in section.
Der Sprechkopf ist, wie bekannt, in zwei zusammenarbeitende Teile α und b unterteilt, von denen jeder eine Magnetspule C enthält, in der ein Polkern d gleitbar ruht. Die zwei Kopfstücke iß und b kommen für gewöhnlich, gegeneinander zu liegen, so daß die Polkerne von entgegengesetzten Seiten her unter Federdruck gegen den Lautsehriftträger anHegen, der in Gestalt eines Stahlbandes e durch eine Führungsrille wandert, die in der Polfläcbe eines Kopfteils vorgesehen ist. Die Kopfteile α und b sind in den Gelenken h und i an dem festen Träger^ angebracht.As is known, the speaking head is divided into two cooperating parts α and b, each of which contains a magnetic coil C in which a pole core d slidably rests. The two head pieces ISS and b usually come to lie against each other, so that the pole cores anHegen from opposite sides under spring pressure against the Lautsehriftträger that migrates in the form of a steel strip e by a guide groove which is provided in the Polfläcbe a head portion. The head parts α and b are attached to the fixed support ^ in the joints h and i.
Auf jedem der Polkerne d lastet Federdruck, der nach der Erfindung durch den federbeeinflußten Stempel / ausgeübt wird, welcher in der Hülse m geführt ist. Djer Stempel/ sitzt an einer Stange o, die in einem Loch der Kappe λ Führung erhält und vonOn each of the pole cores d there is a spring pressure which, according to the invention, is exerted by the spring-influenced stamp / which is guided in the sleeve m. Djer stamp / sits on a rod o that receives guidance in a hole in the cap and from
