Description

Es sind fotografische Objektivverschlüsse bekannt, in denen ein Blitzlichtschalter eingebaut ist. Diese Einrichtung bezweckt, daß gleichzeitig mit dem Öffnen der Verschlußblätter ein elektrischer Stromkreis geschlossen wird, welcher eine Blitzlampe enthält. Da aber die letztere nicht unmittelbar am Verschluß, sondern meist in einem Halter am Kameragehäuse angebracht ist, so muß eine elektrische Verbindungsleitung mit entsprechendem Kontaktstecker vorgesehen sein. Die Erfindung bezieht sich auf eine besonders vorteilhafte Anbringung dieser Steckvorrichtung am Verschluß.There are photographic lens shutters known in which a flashlight switch is built in. The purpose of this device is that simultaneously with the opening of the shutter blades an electrical circuit is closed which contains a flash lamp. There but the latter is not directly on the lock, but mostly in a holder is attached to the camera housing, an electrical connection cable must be included corresponding contact plug can be provided. The invention relates to a particularly advantageous attachment of this plug-in device to the closure.

Nach der Erfindung wird die Steckvorrichtung schräg an der vorderen Stirnseite des Verschlusses angebaut. Diese Anbringung hat die Vorteile, daß der Objektivträger nicht durchbohrt werden muß, wenn der Verschluß, wie das z. B. bei der Verwendung in einer Kleinbildkamera meistens der Fall ist, in den Objektivträger eingebaut und von letzterem zum Teil umschlossen ist. Außerdem wird hier auch vermieden, daß der Stecker oder die elektrische Leitung in den Aufnahmelichtkegel ragt, was leicht der Fall sein könnte, wenn der Stecker senkrecht zur Stirnfläche des Verschlusses angebracht wäre. In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt, und zwar zeigt Abb. i eine Ansicht und Abb.2 eine Seitenansicht eines fotografischen Verschlusses mit einer elektrischen Steckvorrichtung. An der Stirnseite i des Objektivverschlusses 2 ist eine Steckerbuchse 3 so angebracht, daß der in sie passende Stecker d schräg nach vorn steht und leicht nach außen geneigt ist. Mit 5 ist die elektrische Leitung bezeichnet, welche die Verbindung zwischen dem Schalter im Objektivverschluß i und der Blitzlampe herstellt.According to the invention, the connector is inclined at the front The front of the lock is attached. This attachment has the advantages that the Lens carrier does not have to be pierced when the shutter, such as the z. B. at the use in a 35mm camera is mostly the case in the lens carrier built in and partially enclosed by the latter. In addition, it is also avoided here that the plug or the electrical cable protrudes into the cone of light, what could easily be the case if the connector is perpendicular to the face of the closure would be appropriate. In the drawing, the subject of the invention is for example shown, namely Fig. i shows a view and Fig.2 shows a side view of a photographic shutter with an electrical connector. At the front i of the lens shutter 2, a socket 3 is attached so that the in the matching connector d is angled forward and tilted slightly outwards. With 5 the electrical line is referred to, which the connection between the Switches in the lens shutter i and the flash lamp.
