Description
Einrichtung zur elektrischen und mechanischen VerbindungDevice for electrical and mechanical connection
des Schirmgeflechtes und der Kupfer folien eines Koaxial-Kabels mit dem Außenleiter eines Steckers Die Erfindung betrifft eine Einrichtung gemäß dem Oberbegriff von Anspruch 1.the braided shield and the copper foils of a coaxial cable with the outer conductor of a plug The invention relates to a device according to the The preamble of claim 1.
Es sind verschiedene Möglichkeiten, wie z.B. Klemmen, Weiehlöten, Crimpen usw., zur elektrischen Verbindung eines Außenleitergeflechts eines Koaxial-Kabels mit dem Außenleiter eines Steckers bekannt. Eine derartige elektrische Verbindung ist infolge des Aufbaues des Koaxial-Kabels nicht so ohne weiteres zu bewerkstelligen. Der Aufbau eines Koaxial-Kabels 1 ist aus Figur 1 ersichtlich. Das Kabel 1 weist einen Innenleiter 2, beispielsweise aus Kupfer auf, der von einem Dielektrikum 3 aus PVC umgeben ist. Auf dem Umfang des Dielektrikums 3 ist ein Schirmgeflecht 4, vorzugsweise aus versilbertem Kupfer angeordnet, das in zwei Lagen Isolierfolie 5 ud 6 eingebettet ist. Die beiden Lagen Isolierfolie 5 und 6 liegen gegenläufig. Auf der äußeren Isolierfolie 6 sind zwei gegenläufige Kupferfolien 7 und 8 angeordnet, die von einer abschließenden Außenisolierungsschicht 9 umgeben sind.There are various options, such as clamping, soldering, Crimping, etc., for the electrical connection of an outer conductor braid of a coaxial cable known with the outer conductor of a plug. Such an electrical connection is not easy to accomplish due to the structure of the coaxial cable. The structure of a coaxial cable 1 can be seen from FIG. The cable 1 has an inner conductor 2, for example made of copper, which is supported by a dielectric 3 is surrounded by PVC. On the circumference of the dielectric 3 is a braided shield 4, preferably made of silver-plated copper arranged in two layers of insulating film 5 ud 6 is embedded. The two layers Insulating foil 5 and 6 lie opposite. On the outer insulating film 6 are two opposing copper foils 7 and 8, which are surrounded by a final outer insulation layer 9 are.
Eine bekannte elektrisch leitende Verbindung zwischen dem Schirmgeflecht 4 mit den beiden gegenläufigen Kupfer folien 7 und 8 eines Koaxial-Kabels 1 und mit dem Außenleiter 10 eines Steckers mit Hilfe einer rohrförmigen Crimp-Hülse 11 ist in Figur 2 dargestellt. Aus dieser Darstellung ist zu entnehmen, daß der Außenleiter 10 unter das Schirmgeflecht 4 und unter die Kupferfolien 7 und 8 geschoben ist.A known electrically conductive connection between the braided shield 4 with the two opposing copper foils 7 and 8 of a coaxial cable 1 and with the outer conductor 10 of a plug with the aid of a tubular crimp sleeve 11 is shown in FIG. From this illustration it can be seen that the outer conductor 10 is pushed under the braided shield 4 and under the copper foils 7 and 8.
Dieses kann wegen der verhältnismäßig festen Wicklung der Kupferfolien 7 und 8 nur dann erfolgen, wenn die beiden Kupferfolien-7 und 8 vorher eingeschnitten werden. Außerdem ist es erforderlich, die Isolierfolien 5 und 6 zu entfernen, um zwischen dem Schirmgeflecht 4 und den Kupfer folien 7 und 8 eine elektrische Verbindung zu erhalten. Erschwerend kommt hinzu, daß infolge der gegenläufigen Schräglage der Kupferfolien 7 und 8 jede Folie einzeln eingeschnitten werden muß, da sonst Segmente aus einer der beiden Folien herausgeschnitten werden würden. Nachteiligerweise läßt sich eine einwandfreie elektrische Verbindung nicht herstellen, da die Kupferfolien 7 und 8 nur eine Stärke von etwa 0,05 mm aufweisen und durch das Einschneiden derart geschwächt werden, daß die schmalen Folienbänder beim Einschieben des Außenleiters 10 unter das Schirmgeflecht 4 bei axialer Belastung infolge eines leichten Zurückschiebens des Schirmgeflechtes 4 abreißen.This can be due to the relatively tight winding of the copper foils 7 and 8 only take place if the two copper foils 7 and 8 have been cut beforehand will. In addition, it is necessary to remove the insulating films 5 and 6 in order to between the braided shield 4 and the copper foils 7 and 8 an electrical connection to obtain. To make matters worse, due to the opposite inclination of the Copper foils 7 and 8 each foil must be cut individually, otherwise segments would be cut out of one of the two foils. Disadvantageously, leaves a proper electrical connection cannot be established because the copper foils 7 and 8 only have a thickness of about 0.05 mm and by cutting in such a way are weakened that the narrow foil strips when inserting the outer conductor 10 under the braided shield 4 with axial load as a result of a slight push back Tear off the braided shield 4.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung der eingangs C;enannten Art zu schaffen, durch die eine mechanisch feste und elektrisch einwandfreie Verbin- dung zwischen dem Schirmgeflecht und den Kupfer folien eines Koaxial-Kabels und dem Außenleiter eines Steckers sichergestellt wird.The invention is therefore based on the object of providing a device of Initially C; to create the type mentioned, by means of which a mechanically solid and electrical perfect connection between the braided shield and the copper foils of a coaxial cable and the outer conductor of a plug is ensured.
