Abstract
Description
Die vorliegende Erfindung betrifft eine Printklemme für Koaxialkabel, welche Printklemme zumindest zwei Anschlüsse aufweist.The present invention relates to a print terminal for coaxial cable, which print terminal has at least two terminals.
Printklemmen sind dem Fachmann in vielerlei Ausführungen bekannt. Gemein ist diesen handelsüblichen Printklemmen, dass sie für Koaxialkabel ungeeignet sind, da der Schirm des Koaxialkabels aufgezwirbelt und anschließend wieder verdrillt werden muss, um ihn in der Printklemme zu fassen. Soll der Schirm auf die gleiche Länge wie die Seele kommen, so wird diese Art der Konfektionierung zusätzlich aufwändig.Print terminals are known to the expert in many designs. Common to these commercial print terminals that they are unsuitable for coaxial cable, since the shield of the coaxial cable must be twisted and then twisted again to take him in the PCB terminal. If the umbrella is to have the same length as the soul, then this type of assembly is additionally complicated.
Die Aufgabe der Erfindung besteht darin, eine Printklemme vorzuschlagen, welche eine platzsparende und kostengünstige Verkabelung ermöglicht.The object of the invention is to propose a print terminal, which allows a space-saving and cost-effective wiring.
Die Aufgabe wird gelöst durch den Gegenstand des unabhängigen Anspruchs 1. Weiterbildungen und Ausgestaltungen der Erfindung finden sich in den Merkmalen der abhängigen Ansprüche wieder.The object is solved by the subject matter of
Erfindungsgemäß umfasst die Printklemme zumindest zwei Anschlüsse, welche koaxial zueinander angeordnet sind. Darüber hinaus weist die Printklemme zumindest eine Öffnung auf, durch welche das Koaxialkabel in beide Anschlüsse einführbar ist. Beide Anschlüsse weisen dabei jeweils einen Anschlussraum auf, in welchen ein Kabel geklemmt werden kann. Beide Anschlussräume weisen dabei eine gemeinsame Längsachse auf.According to the invention, the print terminal comprises at least two terminals which are arranged coaxially with each other. In addition, the print terminal has at least one opening through which the coaxial cable can be inserted into both terminals. Both connections each have a connection space in which a cable can be clamped. Both connection spaces have a common longitudinal axis.
Vorteile der Erfindung sind, dass eine Verbindung von Printklemme und Koaxialkabel günstig und platzsparend erfolgt und die aufwändige Aufzwirbelung und Verdrillung des Koaxialschirms entfällt, da die Printklemme der Geometrie von Koaxialkabeln angepasst ist. Die Montage der Kabel kann mit handelsüblichem Werkzeug durchgeführt werden.Advantages of the invention are that a connection of print terminal and coaxial cable is cheap and space-saving and eliminates the costly Aufzwirbelung and twisting of Koaxialschirms, since the print terminal of the geometry of coaxial cables is adjusted. The installation of the cables can be carried out with commercially available tools.
Gemäß einer erfindungsgemäßen Weiterbildung sind beide Anschlüsse zur Aufnahme von Kabeln oder Litzen unterschiedlicher Querschnitte, insbesondere unterschiedlicher Durchmesser, geeignet. Beide Anschlussräume weisen entsprechend unterschiedliche Querschnitte längs zur gemeinsamen Längsachse auf, insbesondere unterschiedliche Abmessungen.According to a development of the invention, both connections are suitable for receiving cables or strands of different cross sections, in particular different diameters. Both connection spaces have correspondingly different cross sections along the common longitudinal axis, in particular different dimensions.
Gemäß einer weiteren Weiterbildung der Erfindung ist ein erster Anschluss zwischen einem zweiten Anschluss und der Öffnung der Printklemme angeordnet, wobei der erste Anschluss geeignet ist, ein Kabel bzw. eine Litze des Koaxialkabels mit einem größeren Querschnitt zu aufzunehmen, insbesondere zu klemmen, als der zweite Anschluss.According to a further development of the invention, a first connection is arranged between a second connection and the opening of the print terminal, wherein the first connection is adapted to receive a cable or a strand of the coaxial cable with a larger cross section, in particular to clamp, than the second one Connection.
Eine weitere Weiterbildung der erfindungsgemäßen Printklemme besteht darin, dass zumindest der erste Anschluss eine senkrecht zur gemeinsamen Achse mit dem zweiten Anschluss angeordnete Schraube zum Klemmen des Kabels im ersten Anschluss aufweist. Allgemein wird eine Printklemme mit einem solchen Klemmmechanismus, Printklemme mit vertikaler Schraube und horizontalem Leiteranschluss genannt.A further development of the print terminal according to the invention consists in that at least the first terminal has a screw arranged perpendicular to the common axis with the second terminal for clamping the cable in the first terminal. In general, a print terminal with such a clamping mechanism, print terminal with a vertical screw and horizontal conductor connection is called.
Alternative weist zumindest der erste Anschluss eine senkrecht zur gemeinsamen Achse mit dem zweiten Anschluss wirkende Feder zum Klemmen eines Kabels im ersten Anschluss auf. Eine derart ausgestaltete Printklemme wird herkömmlicherweise als Printklemme mit vertikaler Feder und horizontalem Leiteranschluss bezeichnet.Alternatively, at least the first connection has a spring acting perpendicular to the common axis with the second connection for clamping a cable in the first connection. Such a designed print terminal is commonly referred to as a print terminal with vertical spring and horizontal conductor connection.
Gemäß einer Ausgestaltung weist zumindest der zweite Anschluss den gleichen Klemmmechanismus, wie der erste Anschluss auf. Im ersten Fall weist der zweite Anschluss somit ebenfalls eine senkrecht zur gemeinsamen Achse mit dem ersten Anschluss angeordnete Schraube zum Klemmen des Kabels im zweiten Anschluss auf. Im zweiten Fall weist der zweite Anschluss entsprechend eine senkrecht zur gemeinsamen Achse mit dem ersten Anschluss wirkende Feder zum Klemmen eines Kabels im zweiten Anschluss auf.According to one embodiment, at least the second connection has the same clamping mechanism as the first connection. In the first case, the second connection thus likewise has a screw arranged perpendicular to the common axis with the first connection for clamping the cable in the second connection. In the second case, the second connection correspondingly has a spring acting perpendicular to the common axis with the first connection for clamping a cable in the second connection.
Eine weitere Weiterbildung der Erfindung ist ein Feldgerät der Automatisierungstechnik, insbesondere der industriellen Prozessautomatisierung, mit einer erfindungsgemäßen Printklemme.A further development of the invention is a field device of automation technology, in particular industrial process automation, with a print terminal according to the invention.
Entsprechende Feldgeräte sind dabei z. B. Durchflussmessgeräte, Füllstandsmessgeräte, Druckmessgeräte oder Messgeräte zur Analyse. Die Koaxialkabel können beispielsweise bereits vom Lieferanten des Kabels vorkonfektioniert sein, d. h. sie sind entsprechend abisoliert und mit Aderendhülsen versehen. Die Montage der Kabel erfolgt dann vor Ort vom Kunden.Corresponding field devices are z. Flowmeters, level gauges, pressure gauges or gauges for analysis. The coaxial cables may for example already be pre-assembled by the supplier of the cable, i. H. they are correspondingly stripped and provided with ferrules. The cables are then installed on site by the customer.
