Description

Die Erfindung bezieht sich. auf eine Stoßklemme zur Verbindung" vön Stromschienen, wie sie an elektrischen Laufkranen, Katzen u. a. ortsveränderlichen Stromverbrauchern benutzt werden.The invention relates to. on a butt clamp to connect "vön Busbars such as those found on electric overhead traveling cranes, cats and others. portable Electricity consumers are used.

Stoßklemmen in derbisherbekanmtenAusführung bestehen aus zwei Laschen, welche unter Schraubendruck auf die Schienenenden geklemmt werden. Sie erfordern ein sorgfältiges Blankfeile.n, oder Schaben der Schienenenden, um einen guten Kontakt zu gewährleisten. Dieses Blankschaben nimmt viel Zeit in Anspruch und führt, wenn es nicht korrekt ausgeführt wird, zu Störungen und Spannungsverlusten. Außerdem ermöglicht die Ausführung der Klemmen, .nur einen verhältnismäßig kleinen spei. Kontaktdruck. Bei Verwendung von Stromschienen mit aufgewalztem Kupferkopf hat man die verzinkten Stoßklemmern so ausgeführt, daß sie den Kupferkopf berühren, um den Kontakt - zu verbessern,. Diese Berührungsstellen führen jedoch erfahrungsgemäß zu elektrolytischen Korrosionen.Butt clamps in the previously known version consist of two lugs, which are clamped onto the rail ends under screw pressure. You require a careful bare file, or scraping the rail ends, to make good contact to ensure. This scraping takes a lot of time and leads when if it is not carried out correctly, interference and loss of voltage result. aside from that allows the execution of the terminals. Only a relatively small storage. Contact pressure. When using busbars with a rolled-on copper head, you have the galvanized butt clamps designed so that they touch the copper head to the Contact - to improve. However, experience has shown that these points of contact lead to electrolytic corrosion.

Zweck der Erfindung ist, diese Übelstände zu beseitigen, indem an der Stoßklemme Kontaktschrauben, angeordnet sind, die es ermöglichen, mit ihren vorteilhaft kegelig ausgebildeten Stirnflächen einen hohen spez. Druck auf die Schiene auszuüben. Dabei dringen die vorzugsweise aus vergütetem Material hergestellten Schrauben in die aus weicherem Flußeisen bestehenden Schienen etwas ein und schaben gleichzeitig durch das Drehen der Sehrauben die Berührungsstellen blank.The purpose of the invention is to remedy these deficiencies by an the butt terminal contact screws, are arranged, which make it possible to use their advantageously conical end faces a high spec. Pressure on the rail exercise. In doing so, they are preferably made of tempered material Screw a little into the rails made of softer fluoro iron and scrape at the same time, by turning the visual screws, the points of contact are bright.

Durch die Anwendung von Kontaktschrauben ergibt sich ferner die Möglichkeit, die Stoßklemme aus einem Stück herzustellen. Besonders geeignet ist dazu ein U-förmiges Profil. Durch Verwendung dieses U-Profils können die Kontaktschrauben gleichzeitig zur mechanischen Verbindung dienen. Die Herstellung einer guten Stoßverbindung ist jetzt denkbar einfach. Nach Aufschieben der Klemme auf den, Sohienenstoß werden die beiden Druckschrauben, fest angezogen und mit den beiden -Muttern gekontert.The use of contact screws also offers the possibility of make the butt clamp out of one piece. A U-shaped one is particularly suitable for this Profile. By using this U-profile, the contact screws can be used at the same time serve for mechanical connection. Making a good butt joint is now very easy. After sliding the clamp onto the sole joint the two pressure screws, tightened and locked with the two nuts.

In der Skizze ist ein Ausführungsbeispiel dargestellt. Die Stoßklemme A befindet sich auf den beiden.Schienenenden (dem Stoß C-C). In dem Steg derKlemme sind zurAufna'hme der beidenlKontaktsdhrauben. Gewinde eingeschnitten. Infolge des verhältnismäßig @hohen, Gewindedruckes ist es angebracht, die Anzahl der Gewindegänge zu erhöhen, was z. B. in einfachster Weise durch Ausdrücken eines Ringwulstes E geschehen kann. Die Kontaktschrauben sind mit F bezeichnet.An exemplary embodiment is shown in the sketch. The butt clamp A is on the two ends of the rail (joint C-C). In the web of the clamp are to pick up the two contact screws. Thread cut. As a result of the relatively @high, thread pressure it is appropriate to the number of thread turns to increase what z. B. in the simplest way by expressing an annular bead E can happen. The contact screws are marked with F.
