Abstract

The lower jaw is extended into a crimp connector and the upper jaw is extended into an arm. When the arm is depressed the upper jaw lifts clear of the lower jaw. The upper jaw has a spike (1) that punctures the insulation around the conductor (4).The lower jaw has a seat (5) against which the insulated conductor rests. The seat positions the insulated conductor opposite the spike. The connector makes electrical contact to conductors without first having to remove their insulation. A spring (7) forces the jaws together.

Description

Anschlußklemme für Meßgerätekabel Terminal for measuring instrument cable

Die Erfindung bezieht sich auf eine Anschlußklemme für Meßgerätekabel der im Oberbegriff des Patentanspruchs 1 genannten Art.The invention relates to a terminal for measuring instrument cables of the type mentioned in the preamble of claim 1.

Zunehmend sind in elektrischen und elektronischen Geräten und Anlagen auch solche Leitungsteile von einer elektrisch isolierenden Hülle umgeben, welche früher offen zugänglich waren. Dies trifft insbesondere auch für die elektrischen Anlagen von Kraftfahrzeugen zu, in denen die elektrischen Leitungen - einzeln oder zu einem Bündel zusammengefaßt - immer häufiger mit Hilfe von Flachsteckern an die einzelnen elektrischen Geräte oder sonstige Anschluß- und Verteilungsklemmen angeschlossen werden. Über die Flachstecker selbst werden dabei häufig Isolierstoff-Hülsen geschoben, um auch an diesen Stellen eine einwandfreie elektrische Isolierung sowie einen Schutz gegen Verschmutzung und Korrosion zu schaffen.Are increasing in electrical and electronic devices and systems also such line parts surrounded by an electrically insulating sheath, which were previously openly accessible. This is especially true for the electrical Systems of motor vehicles too, in which the electrical lines - individually or combined in a bundle - more and more often with the help of flat plugs to the individual electrical devices or other connection and distribution terminals connected will. Insulating sleeves are often pushed over the flat connectors themselves, To ensure perfect electrical insulation and protection at these points as well against pollution and corrosion.

So vorteilhaft sich die Verwendung von Isolierstoff-Hülsen auch auf die Störanfälligkeit etc. der elektrischen Anlage auswirkt, so nachteilig macht sie sich bemerkbar, wenn - beispielsweise im Rahmen von Wartungs- oder Reparaturarbeiten - elektrische Meßgeräte zur Funktionsüberprüfung der elektrischen Anlage angeschlossen werden müssen.The use of insulating sleeves is also advantageous the susceptibility to failure etc. affects the electrical system, so makes disadvantageous they become noticeable when - for example during maintenance or repair work - Electrical measuring devices connected to check the functioning of the electrical system Need to become.

Üblicherweise sind die Meßgerätekabel mit sogenannten Krokodilklemmen ausgerüstet, die nur an metallisch blanken Stellen des Leiters bzw.The measuring device cables are usually equipped with so-called alligator clips that are only installed on bare metal areas of the conductor or

der Klemmen des Gerätes angeschlossen werden können. Zur Iurchfuhrng von Messungen ist es in diesen Fällen daher immer erst erforderlich, die Isolierstoff-Hülsen von den Flachsteckern bzw. den Klemmen des Gerätes abzuziehen und nach vollendeter Messung wieder auf diese aufzuschieben.the terminals of the device can be connected. For implementation from In these cases it is therefore always necessary to take measurements, the insulating material sleeves from the flat plugs or the terminals of the device and after completion Postpone measurement on this again.

Der Erfindung liegt die Aufgabe zugrunde, eine Anschlußklemme für Meßgerätekabel zu schaffen, mit der es möglich ist einen elektrischen Kontakt zu einem von einer Isolierstoff-Hülse umgebenen elektrischen Leiter herzustellen, ohne daß zuvor die Isolierstoff-Hülse entfernt oder verschoben werden muß.The invention has for its object to provide a terminal for To create measuring device cables with which it is possible to make electrical contact to produce an electrical conductor surrounded by an insulating sleeve without that the insulating sleeve must be removed or moved beforehand.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 erfüllt. Besonders vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.According to the invention, this object is achieved by the characterizing features of claim 1 met. Particularly advantageous refinements and developments of the invention are specified in the subclaims.

Anhand eines Ausführungsbeispieles wird die Erfindung näher erläutert.The invention is explained in more detail using an exemplary embodiment.

In der einzigen Figur der Zeichnung ist eine zangenähnlich ausgebildete Anschlußklemme, ähnlich einer bekannten Krokodilklemme, dargestellt, deren beide gegeneinander schwenkbare Klemmschenkel mit 2 und 3 beziffert sind. Die beiden Klemmschenkel werden unter der Wirkung einer Federvorrichtung 7 zusammengedrückt. Der obere Klemmschenkel 2 trägt auf seiner dem unteren Klemmschenkel 3 zugewandten Innenseite eine nadelförmige, elektrisch leitende Kontaktspitze ein, welche mit dem nicht weiter dargestellten elektrischen Leiter zum Anschluß an das Meßgerätekabel elektrisch leitend verbunden ist.In the only figure of the drawing is a pliers-like design Terminal, similar to a known alligator clip, shown, both of which mutually pivotable clamping legs with 2 and 3 are numbered. The two clamp legs are compressed under the action of a spring device 7. The upper clamp leg 2 carries on its inner side facing the lower clamping leg 3 a needle-shaped, electrically conductive contact tip, which is not shown in detail with the electrical conductor for connection to the measuring device cable connected in an electrically conductive manner is.

Die stecknadelartige Kontakt spitze 1 dringt durch die Isolierstoff-Hülse eines von der Anschlußklemme umfaßten elektrischen Leiters 4 hindurch und trifft dadurch auf dessen metallische Seele, wodurch der gewünschte elektrische Kontakt zwischen der Anschlußklemme bzw. dem daran angeschlossenen Meßgerätekabel und der elektrischen Leitung hergestellt ist.The pin-like contact tip 1 penetrates through the insulating sleeve an electrical conductor 4 encompassed by the connecting terminal passes through and meets thereby on its metallic core, creating the desired electrical contact between the connection terminal or the measuring device cable connected to it and the electrical line is established.

Die Federkraft der Federvorrichtung 7 ist mit Vorteil größer bemessen als die Federkraft üblicher Krokodilklemmen, so daß die Kontaktspitze 1 im allgemeinen Isolierstoff-Hülsen durchdringen kann, ohne qaß die beiden Klemmschenkel zusätzlich manuell zusammengedrückt werden müssen.The spring force of the spring device 7 is advantageously larger than the spring force of conventional alligator clips, so that the contact tip 1 in general Insulating material sleeves can penetrate without qass the two clamping legs in addition have to be squeezed manually.

Im Ausfuhrungsbeispiel ist der untere Klemmschenkel 3 auf seiner Innenseite in Höhe der Kontaktspitze 1 mit einer mit der Kontaktspitze zusammenwirkenden Druckfläche 5 versehen, durch welche die räumliche Lage des in die Anschlußklemme eingeführten elektrischen Leiters 4 fixiert wird. Die Druckfläche 5 und die Kontaktspitze 1 sind dabei derart angeordnet und bemessen, daß die Kontakt spitze bei geschlossener Anschlußklemme zumindest annähernd auf der Druckfläche 5 aufliegt, wodurch das Druchdringen der Isolierstoff- Hülse des elektrischen Leiters 4 erleichtert wird.In the exemplary embodiment, the lower clamping leg 3 is on its inside at the level of the contact tip 1 with a pressure surface that interacts with the contact tip 5 provided, through which the spatial position of the inserted into the terminal electrical conductor 4 is fixed. The pressure surface 5 and the contact tip 1 are arranged and dimensioned in such a way that the contact tip when the terminal is closed at least approximately rests on the pressure surface 5, whereby the penetration of the Isolierstoff- sleeve of the electrical conductor 4 is facilitated.

Mit 6 sind übliche elektrisch leitende Zähne beziffert, mit denen übliche blanke Leiter und Klemmen in üblicher Weise kontaktiert werden können.The usual electrically conductive teeth are numbered with 6, with which Usual bare conductors and terminals can be contacted in the usual way.

Es versteht sich, daß auch mehr als nur eine Kontaktspitze vorgesehen werden kann und daß insbesondere auch beide Klemmschenkel mit derartigen Kontaktspitzen ausgerüstet sein können. Die Verwendung nur einer Kontaktspitze bietet jedoch den Vorteil, daß die benötigte Federkraft zum Durchdringen der Isolierstoff-Hülse relativ gering bleibt. Die Verwendung mehrerer Kontakt spitzen erleichtert demgegenüber u. U. das Kontaktieren und verringert den elektrischen Übergangswiderstand zwischen elektrischem Leiter und Anschlußklemme.It goes without saying that more than just one contact tip is also provided can be and that in particular both clamping legs with such contact tips can be equipped. However, the use of only one contact tip offers that Advantage that the required spring force to penetrate the insulating sleeve is relative remains low. The use of several contact tips, on the other hand, makes it easier possibly the contacting and reduces the electrical contact resistance between electrical conductor and connector.
