Description

Die Erfindung betrifft eine Schirmklemme nach dem Oberbegriff des unabhängigen Patentanspruchs. The invention relates to a shield terminal according to the preamble of the independent claim.

Die Erfindung befasst sich insbesondere mit der Abschirmung elektromagnetischer Felder. Um die Verträglichkeit mechatronischer Systeme im medizinischen Bereich hinsichtlich elektromagnetischer Strahlung (EMV) zu gewährleisten, erfolgt eine Auflage der Kabelabschirmung auf Masse. Die Schirmauflage kann durch verschiedene Systeme, z.B. durch einen einfachen Kabelbinder aus Kunststoff, Obo-Schellen aus Metall oder sogenannter Omega-Klemmen aus Metall realisiert werden. The invention is particularly concerned with the shielding of electromagnetic fields. In order to ensure the compatibility of mechatronic systems in the medical field with regard to electromagnetic radiation (EMC), the cable shield is grounded. The shield pad can be replaced by various systems, e.g. be realized by a simple plastic cable ties, metal obo clamps or so-called metal omega clamps.

Omega-Klemmen aus Metall zum Halten und Festklemmen mehrerer Schirmkabel sind von der Firma Icotek bekannt. Beispielsweise sind solche Schirmklemmen auf der Homepage der Firma Icotek www.icotek.de insbesondere in deren dort erhältlichen Produktkatalog auf Seite 70 (Stand 29.11.2011) gezeigt. Des Weiteren ist aus der Patentschrift DE 10 2009 006 730 B3 eine Vorrichtung zum Halten und Festklemmen mehrerer Schirmkabel mittels Schirmklemmen auf einer U-förmigen Schiene bekannt. Diese Vorrichtung zeichnet sich dadurch aus, dass Schirmklemmen an einer Spange befestigt sind, und diese auf eine U-förmige Schiene aufgesteckt werden kann. Benachbarte Schirmklemmen werden hierbei in Querrichtung zur Längsachse der U-förmigen Schiene gegeneinander versetzt auf den Spangen angeordnet. Dabei werden – wie in Absatz 0024 beschrieben, die Spange und das Fußteil der Schirmklemme durch Löten miteinander verbunden. Die Spange und Schirmklemme können aber auch einteilig konstruiert sein. Metal omega terminals for holding and clamping several shielded cables are known by Icotek. For example, such screen clamps are shown on the homepage of the company Icotek www.icotek.de in particular in their product catalog available there on page 70 (as of 29.11.2011). Furthermore, from the patent DE 10 2009 006 730 B3 a device for holding and clamping a plurality of shielding cable by means of shield clamps on a U-shaped rail. This device is characterized in that screen clamps are attached to a clip, and this can be plugged onto a U-shaped rail. Adjacent shielding clamps are arranged offset in this case in the transverse direction to the longitudinal axis of the U-shaped rail against each other on the clasps. In this case - as described in paragraph 0024, the clasp and the foot part of the shield terminal connected by soldering. The clip and shield clamp can also be constructed in one piece.

Ungünstig bei dieser Lösung ist, dass die Verbindung auf ein Trägerblech bzw. Gehäuse oder auch einer Schiene immer mechanisch erfolgt, z.B. durch eine Nietverbindung (Verlöten) bzw. durch eine Schraubverbindung. Dadurch ergeben sich Nachteile in der Montage bzw. Demontage, da entweder ein Aufbohren der Niete bzw. ein Lösen der Schraubverbindung notwendig ist. Unfavorable in this solution is that the connection always takes place mechanically on a support plate or housing or a rail, e.g. by a rivet connection (soldering) or by a screw connection. This results in disadvantages in the assembly or disassembly, since either a drilling of the rivet or a loosening of the screw connection is necessary.

Der Erfindung liegt die Aufgabe zugrunde, eine Schirmklemme der eingangs genannten Art so auszugestalten, dass sie einfach, sicher und effizient montiert bzw. demontiert werden kann. The invention has the object of providing a shield terminal of the type mentioned in such a way that it can be easily, safely and efficiently assembled or disassembled.
