Abstract

The screw has a thread shaft and a head (12), where a stripped end (16) of an electrical cable (18) for voltage pick up is firmly fixed with the head. The end is fixed in a radial borehole (20) of the head by pressing, soldering, welding, sticking, clamping or screwing process. The inner surface of the head is covered with an insulating layer, and the head has nut which is screwed on the thread shaft.

Description

Die Erfindung betrifft eine Schraube mit einem Gewindeschaft und einem Kopf für elektrische Kabelanschlüsse.The The invention relates to a screw with a threaded shaft and a Head for electrical cable connections.

Bei bekannten Kabelanschlüssen umfasst eine am Kabelende angebrachte Öse die Schraube, die im befestigten Zustand den elektrischen Kontakt sicherstellt. Beim Festziehen der Schraube kann allerdings die Kabelöse aufgrund des Reibschlusses verdreht werden und das Kabel in eine unerwünschte Richtung lenken oder durch Knicken und Zugbelastung verletzen. Ein entscheidender Nachteil der bekannten elektrischen Verbindung mittels Schraube und Kabelöse besteht darin, dass die unvermeidbaren Übergangsströme zwischen Öse, Schraube und dem Gegengewindeteil, in das die Schraube eingeschraubt ist, die elektrische Verbindung korrosionsanfällig machen.at known cable connections For example, an eyelet attached to the end of the cable has the screw in place Condition ensures the electrical contact. When tightening the However, screw can twist the cable eye due to the frictional engagement and direct the cable in an undesirable direction or hurt by kinking and tensile load. A decisive disadvantage the known electrical connection by means of screw and cable eye exists in that the unavoidable transient currents between eyelet, screw and the mating thread part into which the screw is screwed, make the electrical connection susceptible to corrosion.

Der Erfindung liegt die Aufgabe zugrunde, eine Schraube zur Verfügung zu stellen, welche die genannten Nachteile vermeidet und einen in der Richtung festgelegten Kabelanschluss ohne Korrosionsprobleme gestattet.Of the Invention is based on the object, a screw available which avoids the disadvantages mentioned and one in the direction specified cable connection without corrosion problems.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass mit dem Kopf der Schraube ein elektrisches Kabel für den Spannungsabgriff fest verbunden ist. Die Verbindung kann in Weiterbildung der Erfindung durch eine Bohrung im Schraubenkopf zur Aufnahme des Kabels erreicht werden, wobei das Kabel in der Bohrung z.B. durch Löten, Pressen oder mit Hilfe einer zweiten Schraube befestigt ist.These Task is according to the invention solved by that with the head of the screw an electrical cable for the voltage tap is firmly connected. The compound can in development of the invention reached through a hole in the screw head for receiving the cable with the cable in the bore e.g. by soldering, pressing or fastened with the help of a second screw.

Nach einem weiteren Merkmal der Erfindung ist der Kopf der Schraube, mindestens aber die Anschlussstelle des Kabels, mit einer isolierenden Schutzschicht überzogen oder vergossen, die den Kontakt mit Luft und korrosionsfördernden Flüssigkeiten verhindert.To a further feature of the invention is the head of the screw, but at least the connection point of the cable, coated with an insulating protective layer or shed the contact with air and corrosive liquids prevented.

Ein bevorzugtes Anwendungsgebiet der Erfindung sind Batterien. Hier kann der erfindungsgemäße Kabelanschluss dazu herangezogen werden, Stromleistung oder auch nur Messwerte abzugreifen, wobei die Gefahr einer Veränderung des elektrischen Abgriffs durch Korrosion ausgeschlossen oder erheblich gemindert ist.One preferred field of application of the invention are batteries. Here can the cable connection according to the invention to be used, power output or even measured values with the risk of a change in the electrical tap is excluded or significantly reduced by corrosion.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, die nachstehend erläutert wird. Darin zeigenOne embodiment The invention is illustrated in the drawing below is explained. Show in it

1 eine schematische Ansicht einer Schraube mit der erfindungsgemäßen Kabelverbindung am Kopf und 1 a schematic view of a screw with the cable connection according to the invention at the head and

2 eine um 90° gedrehte Ansicht der Schraube. 2 a 90 ° rotated view of the screw.

Die Schraube 10 besteht in bekannter Weise aus einem Kopf 12 und einem Gewindeschaft 14. Sie ist aus elektrisch leitendem Material hergestellt. Der Kopf 12 kann durch eine auf den Schaft 14 aufgeschraubte Mutter ersetzt werden.The screw 10 consists in a known manner from a head 12 and a threaded shaft 14 , It is made of electrically conductive material. The head 12 can through one on the shaft 14 screwed nut to be replaced.

Am Kopf 12 ist das abisolierte Ende 16 eines elektrischen Kabels 18 befestigt. Hierzu ist in den Kopf 12 eine vorzugsweise radiale Bohrung 20 eingearbeitet, die im Beispiel der 1 ein selbst schneidendes Innengewinde 22 hat.At the head 12 is the stripped end 16 an electric cable 18 attached. This is in the head 12 a preferably radial bore 20 incorporated in the example of the 1 a self-cutting internal thread 22 Has.

Im Ausführungsbeispiel der 2 ist das Ende 16 des Kabels 18 durch Pressen in der Bohrung 20 des Kopfes 12 befestigt, was durch die Eindrucksicke 24 an der inneren Oberfläche 26 des Kopfes 12 angedeutet ist. – Weitere erfindungsgemäße Kabelverbindungen können beispielsweise durch Löten, Kleben oder Schweißen hergestellt werden.In the embodiment of 2 is the end 16 of the cable 18 by pressing in the hole 20 Of the head 12 attached, resulting in the impression 24 on the inner surface 26 Of the head 12 is indicated. - Other cable connections according to the invention can be produced for example by soldering, gluing or welding.

Je nach Anwendung der Erfindung kann die Verbindung des Kabels 18 mit der Schraube 10, ggf. mit der zuvor erwähnten Schutzbeschichtung, vor oder nach der endgültigen Montage der Schraube 10 erfolgen.Depending on the application of the invention, the connection of the cable 18 with the screw 10 optionally with the aforementioned protective coating, before or after the final installation of the screw 10 respectively.

Wie bereits erwähnt, umfasst die Erfindung auch eine Kabelverbindung, bei der das Kabel 18 fest an einer den Kopf 12 ersetzenden Mutter angebracht ist, welche dann ihrerseits auf einen vorhandenen Gewindebolzen aufgeschraubt wird, z.B. den Anschlussbolzen einer Batterie. Anstatt in den Anschlussbolzen ein Außengewinde zu schneiden, kann dieser auch mit einem Innengewinde versehen werden, in das dann die erfindungsgemäße Schraube 10 eingeschraubt wird.As already mentioned, the invention also includes a cable connection in which the cable 18 stuck to one's head 12 replacing nut is attached, which in turn is screwed onto an existing threaded bolt, such as the terminal bolt of a battery. Instead of cutting an external thread in the connecting bolt, it can also be provided with an internal thread, into which then the screw according to the invention 10 is screwed in.

Eine besonders vorteilhafte Lösung vor allem auf dem Gebiet von Industrie- oder Fahrzeugbatterien wird darin gesehen, an jeder Batteriezelle anstelle eines festen Anschlussbolzens in die Zellendecke aus Kunststoff eine Bohrung mit einer darin eingesetzten Metallhülse einzuarbeiten, deren Gewinde zur Aufnahme des Gewindeschaftes 14 der Schraube 10 nach der Erfindung dient. Hier ist es besonders vorteilhaft, die innere Oberfläche 26 des Kopfes 12 mit einer Isolierschicht aus Kunststoff zu überziehen, die nach dem Festziehen der Schraube 10 einen innigen, dichtenden Kontakt mit der Kunststoffoberfläche der Batteriezelle herstellt. Diese Dichtwirkung ist besonders effizient, wenn ein weicher mit einem harten Kunststoff gepaart wird, beispielsweise Polypropylen für die Zellendecke und ABS für die Oberfläche 26 des Kopfes 12.A particularly advantageous solution, especially in the field of industrial or vehicle batteries is seen to incorporate at each battery cell instead of a fixed connection bolt in the cell cover made of plastic a bore with a metal sleeve inserted therein, the thread for receiving the threaded shaft 14 the screw 10 used according to the invention. Here it is particularly beneficial to the inner surface 26 Of the head 12 To coat with an insulating layer of plastic, after tightening the screw 10 creates an intimate, sealing contact with the plastic surface of the battery cell. This sealing effect is particularly efficient when a soft is paired with a hard plastic, for example polypropylene for the cell cover and ABS for the surface 26 Of the head 12 ,
