Description

Schraubenlose Klenunvorrichtung Es sind schraubenlose Klemmvorrichtungen bekannt, die aus einem doppelkegeligen Gehäuse bestehen, in das eine ebensolche Metallbüchse eingesetzt ist. In letzterer sind zwei Klemmstücke, beispielsweise zwei Kuggeln, längsverschirblich und durch eine zwischen ihnen angeordnete Druckfeder so gegen die kleinen Keg .,elquerschnitte der inneren Metallbüchse gepreßt, daß jeweils zwischen den Kugeln und den Wandflächen der Metallbüchse von beiden Seiten her eingeführte Leitungsdrähte fest verklemmt sind. Das Klemmstück ermöglicht also eine einfache elektrische Verbindung zwischen zwei Drahtenden, die leicht zu bewerkstelligen ist und sicher hält.Screwless clamps There are screwless clamps known, which consist of a double-conical housing, in which a similar one Metal sleeve is used. In the latter are two clamping pieces, for example two balls, can be moved lengthways and by a compression spring arranged between them so pressed against the small kegs, cross-sections of the inner metal sleeve that each between the balls and the wall surfaces of the metal sleeve from both sides lead wires introduced are firmly clamped. So the clamping piece enables a simple electrical connection between two wire ends that is easy to make is and holds securely.

Da die Herstellung des doppelkegeligen Klemmstückes aus einem Stück bisher erhebliche Schwierigkeiten bereitete, wurden die beiden Kegel der Metallbüchse über ihren aneinanderstoßenden Flächen verschraubt oder sonstwie zusamengefügt. Nun traten aber selbst bei sorgfältigster Vereinigung der Metallbüchsen dadurch Schwierigkeiten auf, daß der Leitungswiderstand an der Verbindungsstelle nicht demjenigen des übrigen Teils der Büchse entspricht und die Verbindung selbst auch nachgab und schadhaft wurde. Das führte dann zu unerwünschten Erwärmunaen und Stromverlusten, aber auch zu Stromunterbrechungen, wenn sich durch irgendwelche andauernden oder stoßweise auftretenden Erschütterungen die Verbindung der beiden Teile löste und wacklig wurde (Wackelkontakt).Because the production of the double-conical clamping piece from one piece so far caused considerable difficulties, the two cones of the metal can screwed or otherwise joined together over their abutting surfaces. But now, even with the most careful union of the metal cans, this stepped through Difficulties that the line resistance at the junction is not that of the rest of the bush and the connection itself also gave way and became defective. This then led to undesirable warming and power losses, but also to power interruptions if caused by any persistent or intermittent vibrations loosened the connection between the two parts and became wobbly (loose contact).

Die Erfindung soll die Herstellung vereinfachen, verbilligen und unzureichende Kontaktgabe ausschließen. Die kegelförmigen Bohrungen für die Aufnahme der Kugel und Druckfeder sollen daher in einem einzigen massiven Metallblock angeordnet sein. Die Bohrungen sollen aus Gründen der Materialersparnis dicht nebeneinander liegen, und zwar so, daß die kleineren Kegelquerschnitte abwechselnd sich g ,egenüberliegen.The invention is intended to simplify, cheaper and inadequate manufacture Exclude contact. The conical holes for the ball and compression spring should therefore be arranged in a single solid metal block. The holes should be close to each other to save material, in such a way that the smaller conical cross-sections alternately lie opposite one another.

Die Figur zeigt einen Querschnitt durch die Verbindungs(lüster)klemme. 1 ist das Isoliergehäuse, 2 der Metallblock, 3 die konische Bohrung, 4 die Kugel und 5 die Feder.The figure shows a cross section through the connecting (luster) clamp. 1 is the insulating housing, 2 is the metal block, 3 is the conical hole, 4 is the ball and 5 is the spring.
