Description
Für Glühlampen hoher Stromstärke, wie sie z. B. bei Projektions- oder Kinoapparaten verwendet werden, genügen die bisher üblichen Lampenfassungen nicht. Insbesondere sind die für Glühlampenfassungen üblichen Schraubkontakte infolge der geringen Kontaktfläche wenig brauchbar.For bulbs with high amperage, such as those used for. B. in projection or cinema equipment are used, the conventional lamp sockets are not sufficient. In particular are the usual screw contacts for incandescent lamp sockets due to the small contact area not very useful.
Die Fassung nach der Erfindung für Glühlampen hoher Belastung beseitigt diese Nachteile; sie ist als sogenannte Steckfassung ausgebildet und besitzt zwei federnde Kontaktringe, die aus Ringsegmenten bestehen und einerseits durdh elastische Bänder stromführend miteinander verbunden sind, anderseits durch auf dem Umfang nebeneinander oder aufeinander angeordnete Federn gegen den Lampensockel gepreßt werden.The socket according to the invention for high load incandescent lamps eliminates these disadvantages; it is designed as a so-called plug-in socket and has two resilient contact rings, which consist of ring segments and on the one hand live through elastic bands are connected to one another, on the other hand by springs arranged next to one another or on top of one another on the circumference the lamp base are pressed.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Abb. 1 zeigt einen Längsschnitt und Abb. 2 einen Querschnitt der Fassung.An exemplary embodiment of the invention is shown in the drawing. Fig. 1 shows a longitudinal section and Fig. 2 a cross section of the socket.
In dem Isolierkörper α sind die Ringkontakte δ und c verschiedenen Durchmessers angeordnet. Diese Ringkontakte bestehen aus einzelnen Ringsegmenten,, die im allgemeinen gleich groß sein können, von denen jedoch zweckmäßig ein Segment eine größere Breite hat als die übrigen. Es empfiehlt sich, diejenigen Segmente größer auszuführen, welche mit den Stromanschlüssen d, e versehen sind. Die einzelnen Segmente der Ringkontakte werden einesteils durch Bänder / und g, anderseits durch Federn h und i zusammengehalten. Die Bänder / und g stellen die elektrische Verbindung zwischen den Ringsegmenten her; die Federnh und i üben den erforderlichen Kontaktdruck auf den Lampensockel aus. Die Enden der Bänder/ und g und der Federn h, i- liegen dabei zweckmäßig auf demjenigen Ringsegment, welches eine größere Breite besitzt als die übrigen. Auf diese Weise ist dafür gesorgt, daß bei dem Auseinanderfedern der Ringsegmente die Enden der Bänder /, g sich nicht weiter als die Breite eines Kontaktsegments voneinander entfernen, wodurch die elektrische Verbindung einzelner Ringsegmente unterbunden wäre. Entsprechend den zwei Kontaktringen in der Steckfassung hat der Glühlampensockel eine der Fassung angepaßte abgesetzte Form.The ring contacts δ and c of different diameters are arranged in the insulating body α. These ring contacts consist of individual ring segments, which can generally be of the same size, but of which one segment is expediently larger than the others. It is advisable to make those segments larger, which are provided with the power connections d, e . The individual segments of the ring contacts are held together on the one hand by bands / and g and on the other hand by springs h and i. The bands / and g establish the electrical connection between the ring segments; the springs h and i exert the required contact pressure on the lamp cap. The ends of the bands / and g and of the springs h, i- are expediently on that ring segment which has a greater width than the others. In this way it is ensured that when the ring segments spring apart, the ends of the strips /, g do not move further apart than the width of a contact segment, which would prevent the electrical connection of individual ring segments. Corresponding to the two contact rings in the plug-in socket, the bulb base has a detached shape that is adapted to the socket.
Zur Sicherung gegen axiale Verschiebung der beiden Ringkontakte sind die-in eines der Ringsegmente eingesetzten Schrauben k, m vorgesehen. Die Federn h, i können aus Rundoder Flachstahl bestehen. In an sich bekannter Weise können diese Federn gegen die schädliche Wirkung der Wärme dadurch geschützt werden, daß sie von den stromführenden Teilen durch wärmeisolierende Zwischenlagen getrennt werden.To secure against axial displacement of the two ring contacts, the screws k, m inserted into one of the ring segments are provided. The springs h, i can be made of round or flat steel. In a manner known per se, these springs can be protected against the harmful effects of heat in that they are separated from the current-carrying parts by heat-insulating intermediate layers.
