Abstract

The connector clamp releasably connects an electric lead in the form of a wire or flex with an electrically conductive contact rail. The clamp has a rotatable clamp plate. When this is pivoted, the clamp plate presses the lead against the plate. This connection can be released when needed, with a suitable tool, by pressing on a locking lug. When required, the clamp plate can be fed from outside into the respective clamp chamber of the housing for stripping the insulation and clamping the lead. The clamp plate and/or the contact rail has not cuts to connect already stripped wires. An elastic housing projection can hold the clamp plate releasably in the clamp position.

Description

Die Erfindung betrifft eine elektrische Verbindungsklemme, die lösbar einen elektrischen Leiter in Draht- oder Litzenform mit einer elektrisch leitenden Kontaktschiene verbindet, wobei eine verdrehbar gelagerte Klemmscheibe, die von außen in das Klemmgehäuse eingeführt wird bei ihrer Schwenkbewegung den Leiter gegen die Kontaktschiene preßt.The invention relates to an electrical connection terminal that removably one electrical conductor in wire or strand form with an electrically conductive Contact rail connects, with a rotatably mounted clamping disc, which by The conductor is inserted into the outside of the terminal housing during its pivoting movement presses against the contact rail.

Der Erfindung liegt die Aufgabe zugrunde eine vielseitige Verbindungstechnik (verwendbar in Reihenklemmen, Leiterplattenanschlußklemmen, oder Klemmenblöcken) zu entwickeln, die eine sichere und großflächige Kontaktstelle bietet, den Leiter vor Verletzungen schützt, sowie eine möglichst einfache Herstellung mit wenigen Einzelteilen bietet und außerdem eine rasche und einfache Handhabung ermöglichet, was ebenfalls zu geringeren Kosten sowohl beim Hersteller als auch beim Verbraucher führt. Durch die von außen zugeführte Klemmscheibe (z B. mittels Anlegewerkzeug) soll es ermöglicht werden, Klemmleisten mit hoher Anschlußdichte herzustellen, die zudem bediener- und montagefreundlich einzusetzen sind. Es ist dabei von Vorteil, in dem Anlegewerkzeug ein Magazin und Hebelwerk vorzusehen; es ist weiterhin vorteilhaft bei hochpoligen Klemmleisten mehrere Anschlüsse parallel, gegebenenfalls maschinell zu verbinden. Bei starkem Isolationsmaterial (großem Leiterquerschnitt), niedrigen Temperaturen oder beim Einsatz in Geräteblöcke (z. B. Schütze), ist es in solchen Fällen weiterhin von Vorteil, die Klemmscheibe und die Kontaktschiene so auszubilden, daß bereits abisolierte Leiter aufgenommen werden können, um diese dann mit dem Prinzip der drehbar gelagerten Klemmscheibe an der Kontaktschiene zu verbinden.The invention has for its object a versatile connection technology (usable in terminal blocks, PCB connection terminals, or Terminal blocks) to develop a safe and large contact point offers, protects the conductor from injuries, and the simplest possible manufacture offers with a few individual parts and also quick and easy handling enables, which also at lower costs for both the manufacturer and Leads consumer. Due to the externally supplied clamping disc (e.g. by means of Application tool), it should be possible to use terminal strips with a high connection density to manufacture, which are also easy to use and install. It is there advantageous to provide a magazine and lever mechanism in the application tool; it is furthermore advantageous with multi-pin terminal strips several connections in parallel, if necessary to connect by machine. With strong insulation material (large Conductor cross-section), low temperatures or when used in device blocks (e.g. Sagittarius), it is still advantageous in such cases, the clamping disc and Design the contact rail so that stripped conductors are already picked up can then with the principle of the rotatably mounted clamping disc on the To connect the contact rail.

Diese Aufgabe wird durch die Merkinale des Anspruches 1 gelöst. This object is achieved by the features of claim 1.

Die Klemmlage kann durch gehäusefeste Rastvorsprünge gesichert werden, die entweder an der Klemmscheibe oder an einem die Klemmscheibe betätigenden Schieber angreifen und lösbar sind. Zur Lagerung der Klemmscheibe können in dem Gehäuse Führungen vorgesehen sein, an denen sich die Außenkontur der Klemmscheibe abstützt.The clamping position can be secured by locking projections fixed to the housing either on the clamping disc or on one that actuates the clamping disc Attack slide and are detachable. To store the clamping disc can in the Housing guides can be provided on which the outer contour of the clamping disc supports.

Der Klemmbereich der Klemmscheibe und die Schneiden zum Abtrennen der Isolierung können an den Querschnitt des Leiters angepaßt sein.The clamping area of the clamping disc and the cutting edges for separating the insulation can be adapted to the cross section of the conductor.

Es ist weiterhin möglich, durch Verbinden mehrerer benachbarter Schieber gleichzeitig mehrere Leiter mit einer Klemmbewegung zu kontaktieren.It is also possible to connect several adjacent sliders at the same time to contact several conductors with one clamping movement.

Zur Verbesserung der Klemmwirkung kann die Kontaktschiene im Klemmbereich blattfederartig eine Vertiefung im Gehäuse überbrücken und so eine Federkraft ausüben.To improve the clamping effect, the contact rail can be used in the clamping area bridge a recess in the housing like a leaf spring and thus a spring force exercise.

Die Klemmverbindung kann bei Bedarf mit einem geeigneten Werkzeug z. B. Schraubenzieher wieder gelöst werden wenn gegen die Rastnase in Gehäuserichtung gedrückt wird.The clamp connection can if necessary with a suitable tool such. B. Screwdriver be loosened again when against the locking lug in the direction of the housing is pressed.
