Description

Fassungseinsatz für Glühlampen Socket insert for incandescent lamps
Vorliegende Erfindung betrifft einen Fassungseinsatz für Glühlampen.The present invention relates to a socket insert for incandescent lamps.
Glühlampen besitzen bekannterweise an ihrem unteren En¬ de einen Gewindekörper, der in eine Glühlampengewindefas- sung eingeschraubt wird.Incidentally, incandescent lamps have a threaded body on their lower end, which is screwed into an incandescent lamp socket.
Die Nachteile der erwähnten Glühlampen assung sind u.a. darin zu erblicken, dass sich infolge von Kondenswasserbil- dung in den Gewindegängen metallische Korrosionserscheinun¬ gen zeigen, die dazu führen, dass z.B. eine Glühlampe nicht mehr aus der Gewindefassung herausgedreht werden kann. Viel¬ fach kommt es sogar vor, dass beim Versuch des Herausschrau- bens, die Glühlampe im Sockel bricht«, Die Glühlampe ist dann zerstört und der Gewindekörper kann nur mit Hilfe eines Werkzeuges und dies nur mit grösster Mühe, aus der Glühlam- penfassung herausgedreht werden.The disadvantages of the aforementioned incandescent lamps include to be seen in the fact that due to the formation of condensation in the threads, metallic corrosion phenomena appear, which lead to e.g. a light bulb can no longer be unscrewed from the threaded socket. In many cases it even happens that when trying to unscrew the bulb breaks in the base «, the bulb is then destroyed and the threaded body can only be screwed out of the bulb holder with the help of a tool and with great effort become.
Ein weiterer Nachteil einer Glühlampen assung kann auch noch darin erblickt werden, dass nicht jede Glühlampe in irgendeine Glühlampenfassung geschraubt werden kann, be¬ sonders dann, wenn diese zu gross ist.Another disadvantage of an incandescent lamp can also be seen in the fact that not every incandescent lamp is in any bulb holder can be screwed, especially if it is too large.
Der Zweck der vorliegenden Erfindung ist ein Fassungs-- einsatz für Glühlampen, der all die oben erwähnten Nachteile eliminiert.The purpose of the present invention is a socket insert for incandescent lamps, which eliminates all the disadvantages mentioned above.
Die vorliegende Erfindung betrifft einen Fassungsein¬ satz für Glühlampen, der hülsenförmig gefertigt ist, wobei in dessen Mantelfläche mindestens eine Oeffnung zum Einset¬ zen einer Kontakthalterung angebracht ist, die mit dem Glühlampengewindekörper in festem Kontakt steht, während am Boden des hülsenförmigen Fassungseinsatzes eine Oeffnung für den Pluskontakt, sowie ein Anschlusskontakt für den Minuspol angebracht ist.The present invention relates to a socket insert for incandescent lamps, which is made in the form of a sleeve, with at least one opening for inserting a contact holder being made in its outer surface, said contact holder being in firm contact with the thread of the incandescent lamp, while an opening for the socket-shaped socket insert the plus contact and a connection contact for the minus pole is attached.
Anhand der beiliegenden Zeichnungen wird die Erfindung anhand zweier Ausführungsbeispiele näher erläutert.The invention is explained in more detail with reference to two exemplary embodiments with reference to the accompanying drawings.
Es zeigen:Show it:

Fig. 2 einen Längsschnitt durch ein zweitesFig. 2 shows a longitudinal section through a second
Ausführungsbeispiel in stark vergrös¬ sertem Massstab gezeichnet.Exemplary embodiment drawn on a greatly enlarged scale.
Die Figur 1 zeigt einen Längsschnitt durch den Fassungs¬ einsatz für Glühlampen mit einer darin gehalterten Glühlampe in stark vergrössertem Massstab gezeichnet, wobei das eine Glühlampengewinde in noch vergrössertem Massstab dar¬ gestellt ist.FIG. 1 shows a longitudinal section through the socket insert for incandescent lamps with an incandescent lamp held therein, drawn on a greatly enlarged scale, the one Incandescent lamp thread is shown on an even larger scale.
Der Fassungseinsatz für eine Glühbirne gemäss Fig. 1 besteht aus einer stromführenden Metallhülse 1. Dies Me- tallhülse besitzt in der Mantelfläche mindestens eine Oeff¬ nung zwecks Aufnahme der Niete 2. Die Stromführung über¬ nimmt sowohl die Metallhülse 1, wie auch die Niete 20 Da¬ mit der Glühlampengewindekörper 3 durch die Niete 2 in festem Kontakt steht, ist die Niete 2 mittels eines Feder- bandes _, federnd fixiert. Die Metallhülse 1 besitzt am Boden 5 die Stromzuführung 6, sowie die Anschlussschrau¬ be 7 für den Minuspol.1 consists of a current-carrying metal sleeve 1. This metal sleeve has at least one opening in the outer surface for receiving the rivet 2. The current supply takes over both the metal sleeve 1 and the rivet 2 0 Since the light bulb thread body 3 is in firm contact through the rivet 2, the rivet 2 is resiliently fixed by means of a spring band _. The metal sleeve 1 has at the bottom 5 the power supply 6 and the connecting screw 7 for the negative pole.
Eine gewöhnliche Glühlampe kann nun mit ihrem Gewinde¬ körper 3 entweder in den hülsenförmigen Fassungseinsatz 1 eingeschraubt werden, wobei der Gewindegang 8 entlang der Niete 2 läuft. Beim Herausnehmen der Glühlampe wird die¬ selbe in entgegengesetzter Drehrichtung geschraubt. Es hat sich aber gezeigt, dass es nicht absolut notwendig ist, dass der Gewindekörper 3 der Glühlampe hinein- oder her- ausgeschraubt zu werden braucht, es genügt, wenn der Ge¬ windekörper 3 ganz einfach hineingedrückt, oder herausge¬ drückt wird. Die durch das Federblatt _ gehalterte Niete 2 ermöglicht es, dass diese sowohl beim Hineindrücken, als auch beim Herausziehen der Glühlampengewindefassung fe- dernd nachgibt.A conventional incandescent lamp can now either be screwed into the sleeve-shaped socket insert 1 with its threaded body 3, the thread 8 running along the rivet 2. When the light bulb is removed, it is screwed in the opposite direction of rotation. However, it has been shown that it is not absolutely necessary for the threaded body 3 of the incandescent lamp to be screwed in or out, it is sufficient if the threaded body 3 is simply pushed in or pushed out. The rivet 2 held by the spring leaf _ enables it to yield in a springy manner both when the bulb thread is pushed in and when it is pulled out.
Am Boden 5 der Metallhülse 1 ist der Pluskontakt der Stromzufuhr durch die Anschlussschraube 6 federnd an der Isoliermasse 9 befestigt. Die stromführende Metallhülse 1 besitzt am Boden 5 eine weitere Anschlussschraube 7, die den Minuspol darstellt. Der hülsenförmige Fassungseinsatz 1 für Glühlampen ist durch den Fassungsmantel 10, der aus einen bekannten Isoliermasse besteht, gegen Aussen gesieh- ert.At the bottom 5 of the metal sleeve 1, the positive contact of the power supply is resiliently attached to the insulating compound 9 by the connecting screw 6. The current-carrying metal sleeve 1 has at the bottom 5 a further connection screw 7, which represents the negative pole. The sleeve-shaped socket insert 1 for incandescent lamps is seen from the outside through the socket jacket 10, which consists of a known insulating compound.
Der Fassungseinsatz 13 im Fassungsmantel 11 mit den Ge¬ windegängen 12 für eine Glühlampe gemäss Fig. 2 besteht aus der Fassungshülse 13 aus leitendem oder auch aus nicht¬ leitendem Material. Es handelt sich hier um einen sogenann- ten reduzierten Fassungseinsatz für Edison-Fassungen für die Grossen E 27 auf E 14. Solche Reduzierungsfassungen können aber für Edison-Fassungen aller Gr ssen eingesetzt werden. Der hülsenförmige Fassungseinsatz 13 besitzt min¬ destens eine Manteldurchb hrung, in die ein durchgehender Federnocken 14 eingesetzt wird, der die Glühlampe, resp. den Glühlampengewindekörper 15 sowohl aussen, als auch in¬ nen arretiert und für die Verpolung sorgt. Der Aussen-. durchmesser des Fassungseinsatzes 13 entspricht dem In¬ nendurchmesser der Fassung E 27 und die Innenbohrung des Fassungseinsatzes 13 entspricht dem äüsseren Gewinde¬ durchmesser der Glühlampe E 14β Mit 16 ist der Pluspol und mit 17 der Minuspol bezeichneteThe socket insert 13 in the socket jacket 11 with the threads 12 for an incandescent lamp according to FIG. 2 consists of the socket 13 made of conductive or non-conductive material. This is a so-called reduced socket insert for Edison sockets for the sizes E 27 to E 14. Such reduction sockets can, however, be used for Edison sockets of all sizes. The sleeve-shaped socket insert 13 has at least one jacket opening, into which a continuous spring cam 14 is inserted, which the light bulb, respectively. the incandescent lamp body 15 is locked both externally and internally and ensures the polarity reversal. The outside. diameter of the socket insert 13 corresponds to the In¬ nendurchmesser amended E 27 and the internal bore of the socket insert 13 corresponds to the diameter of the bulb äüsseren Gewinde¬ E 14 β at 16 is the positive pole and the negative pole is designated 17
Die Vorteile des erfindungsgemässen Fassungseinsatzes für Glühlampen sind vielfältig. Der Glühlampenfassungs- einsatz benötigt kein Innengewinde mehr, was für die Fab¬ rikation einfacher und billiger wird, sodass die Herstel¬ lungskosten beträchtlich gesenkt werden können» Der Ge¬ windesockel der Glühlampe ist als solcher wohl noch vor- handen, aber der Mantel der Glühlampenfassung muss nicht mehr als Gewinde ausgebildet sein. Korrosionserscheinungen werden vermindert, da die Mantelfläche des Fassungsein¬ satzes eine geringere Berührungsfläche mit dem Gewinde- sockel einer herkömmlichen Glühlampe aufweist. Der erfin- dungsgemässe, hülsenförmige Fassungseinsatz eignet sich für alle konventionellen Glühlampenfabrikate, ohne dass der Glühlampengewindekörper verändert werden müsste. The advantages of the socket insert according to the invention for incandescent lamps are numerous. The bulb holder insert no longer requires an internal thread, which is simpler and cheaper for manufacturing, so that the production costs can be considerably reduced. The threaded base of the bulb as such is probably still available, but the jacket of the bulb holder no longer needs to be designed as a thread. Corrosion phenomena are reduced since the outer surface of the socket insert has a smaller contact area with the threaded base of a conventional incandescent lamp. The sleeve-shaped lampholder insert according to the invention is suitable for all conventional types of incandescent lamps without having to change the thread of the incandescent lamp.
