Elektronisches Gerät, insbesondere AutomatisierungsgerätElectronic device, in particular automation device
Die Erfindung bezieht sich auf ein elektronisches Gerät, ins¬ besondere ein Automatisierungsgerät, nach dem Oberbegriff des Anspruchs 1.The invention relates to an electronic device, in particular an automation device, according to the preamble of claim 1.
Ein derartiges elektronisches Gerät ist aus dem "Handbuch des 19"-Aufbausystems" von Dr. Dirk Hesse, Markt & Technik Ver¬ lag, 1986, Seiten 286 bis 293 bekannt. Das elektronische Ge¬ rät besteht aus einem Grundgerät und einer Einrichtung zum Anschluß von externen Leitungen, die dort als Federleiste ausgeführt ist. Das Grundgerät ist durch elektronische Bau- gruppen realisiert, die in Baugruppenträgem angeordnet sind. Die Federleiste weist ein Gehäuse auf, in dem Federkraft- klemmen gelagert sind. Diese Federkraftklemmen sind mit Fe¬ dern der Federleiste, die auf der Außenseite des Gehäuses liegen und zu einem Frontstecker auf einer elektronischen Baugruppe des Grundgeräts korrespondieren, durch eine Strom¬ schiene elektrisch verbunden. Öffnungen, durch welche im ge¬ steckten Zustand der Federleiste ein geeignetes Werkzeug, z. B. ein Schraubendreher, zum Öffnen der Federkraftklemmen einführbar ist, sowie Öffnungen, durch welche externe Leitun- gen in die Federkraftklemme einlegbar sind, befinden sich ne¬ beneinander auf der den Federn abgewandten Seite des Gehäu¬ ses. Vor Einführen einer abisolierten externen Leitung ist die Federkraftklemme geschlossen. Sie wird durch Herunter¬ drücken einer Käfigzugfeder mit einem Werkzeug geöffnet. Nach Einführung der externen Leitung und Entfernen des Werkzeugs wird der Leiter durch eine Klemmfläche der Federkraftklemme flach gegen die Stromschiene gedrückt. Da die Betätigungs¬ öffnung zum Einführen des Werkzeugs und die Öffnung für die externe Leitung nebeneinander auf derselben Seite des Gehäu- ses angeordnet sind, hat die bekannte Einrichtung zum An¬ schluß externer Leitungen den Nachteil, daß sich die Verdrah¬ tung wegen der engen Platzverhältnisse zeitaufwendig und O 96/08853 PCI7DE95/01224Such an electronic device is known from the "Manual of the 19" construction system "by Dr. Dirk Hesse, Markt & Technik Verlag, 1986, pages 286 to 293. The electronic device consists of a basic device and a device for connection from external lines, which is designed as a female connector. The basic device is implemented by electronic modules which are arranged in subracks. The female connector has a housing in which spring-loaded terminals are mounted.

2 schwierig gestaltet. Ebenso können, da die Sicht auf die Öff¬ nungen für die externen Leitungen durch das Werkzeug behin¬ dert werden kann, Verdrahtungsfehler durch Verwechslung der Federkraftklemmen auftreten.2 difficult designed. Likewise, since the view of the openings for the external lines can be obstructed by the tool, wiring errors can occur due to confusion of the spring-loaded terminals.
Der Erfindung liegt die Aufgabe zugrunde, ein elektronisches Gerät, insbesondere ein Automatisierungsgerät, zu schaffen, das einen einfachen und fehlersicheren Anschluß externer Lei¬ tungen ermöglicht.The invention has for its object to provide an electronic device, in particular an automation device, which enables a simple and fail-safe connection of external lines.
Zur Lösung dieser Aufgabe weist das neue elektronische Gerät der eingangs genannten Art die im kennzeichnenden Teil des Anspruchs 1 genannten Merkmale auf. In den Unteransprüchen sind vorteilhafte Weiterbildungen der Erfindung angegeben.To solve this problem, the new electronic device of the type mentioned has the features mentioned in the characterizing part of claim 1. Advantageous developments of the invention are specified in the subclaims.
Anhand der Figur, in der ein Ausführungsbeispiel der Erfin¬ dung dargestellt ist, werden im folgenden die Erfindung sowie Ausgestaltungen und Vorteile näher erläutert.The invention, embodiments and advantages are explained in more detail below with reference to the figure, in which an embodiment of the invention is shown.
Ein erfindungsgemäßes elektronisches Gerät weist ein in der Figur nicht dargestelltes Grundgerät auf, das in bekannter Weise mit in einem Baugruppenträger gesteckten Baugruppen aufgebaut sein kann. Weiterhin ist es mit einer Einrichtung zum Anschluß externer Leitungen versehen, deren Schnittbild in der Figur gezeigt ist. In einem Automatisierungsgerät wird diese Einrichtung beispielsweise zum Anschluß von Aktoren und Sensoren an Peripheriebaugruppen benötigt. Die notwendige Verdrahtung erfolgt am Einsatzort. In einem Gehäuse 1 der Einrichtung sind mehrere Federkraftklemmen senkrecht zur Zeichnungsebene hintereinander angeordnet, von denen in der Zeichnung lediglich die Federkraftklemme 2 sichtbar ist. Über einen Flachkontakt 3 ist die Federkraftklemme 2 mit einer Fe¬ der 4 verbunden, die zur Kontaktierung eines nicht darge¬ stellten Frontsteckers einer Peripheriebaugruppe dient. Auf dem Rücken des biegsamen Schenkels der Federkraftklemme 2 liegt ein drehbar gelagerter Hebel 5 auf. Auf dessen Rücken wiederum befindet sich die Angriffsfläche für ein Betäti- gungswerkzeug 6, 7 oder 8, beispielsweise ein Schrauben¬ dreher, der durch Betätigungsöffnungen A, B bzw. C in das Ge¬ häuse 1 einführbar ist, auf dem Rücken des Hebels 5 gleitet und diesen maximal bis zu einer Anschlagfläche 9 nieder- drückt. Die Spitze eines Schraubendrehers als Werkzeug in den Betätigungsöffnungen sowie die Lage des drehbar gelagerten Hebels 5 und der Federkraftklemme 2 in Anschlagposition sind in der Figur mit strichpunktierten Linien eingezeichnet. Bei geöffneter Federkraftklemme 2 kann ein ebenfalls strichpunk- tiert gezeichneter Draht 10 durch eine Öffnung 11, die eben¬ falls aus der Betätigungsrichtung A zugänglich ist, eingelegt werden. Zur Aufnahme mehrerer in der Einrichtung hintereinan¬ derliegender Drähte ist über den Öffnungen für die verschie¬ denen Federkraftklemmen, die senkrecht zur Zeichnungsebene hintereinander angeordnet sind, ein Kabelkanal 12 vorgesehen, der nach erfolgter Verdrahtung mit einer Tür 13 verschließbar ist.An electronic device according to the invention has a basic device, not shown in the figure, which can be constructed in a known manner with modules plugged into a rack. Furthermore, it is provided with a device for connecting external lines, the sectional view of which is shown in the figure. In an automation device, this device is required, for example, for connecting actuators and sensors to peripheral modules. The necessary wiring is carried out on site. In a housing 1 of the device, a plurality of spring clips are arranged one behind the other perpendicular to the plane of the drawing, of which only the spring clip 2 is visible in the drawing. The spring-loaded terminal 2 is connected via a flat contact 3 to a spring 4, which is used for contacting a front connector (not shown) of a peripheral module. A rotatably mounted lever 5 rests on the back of the flexible leg of the spring-loaded terminal 2. On its back there is the target for an actuation Power tool 6, 7 or 8, for example a screwdriver, which can be inserted into the housing 1 through actuation openings A, B or C, slides on the back of the lever 5 and presses it down as far as possible up to a stop surface 9. The tip of a screwdriver as a tool in the actuation openings and the position of the rotatably mounted lever 5 and the spring clamp 2 in the stop position are shown in the figure with dash-dotted lines. When the spring-loaded terminal 2 is open, a wire 10, which is also shown in dash-dotted lines, can be inserted through an opening 11 which is also accessible from the actuation direction A. A cable duct 12 is provided above the openings for the various spring-loaded terminals, which are arranged one behind the other perpendicular to the plane of the drawing, to accommodate a plurality of wires lying one behind the other in the device.
In der Betätigungsrichtung A kann eine Verdrahtung oder Kor- rektur sowohl im gesteckten Zustand der Anschlußeinrichtung, d. h. wenn sie auf den FrontStecker einer Flachbaugruppe ge¬ steckt ist, erfolgen, als auch wenn sie nicht an das Grund¬ gerät angeschlossen ist. In vorteilhafter Weise wird die Sicht auf die Öffnungen für die externen Leitungen nicht durch ein Werkzeug behindert, wenn dies durch Öffnungen der Betätigungsrichtungen B oder C eingeführt wird. Dazu ist es meist erforderlich, die Anschlußeinrichtung vom Frontstecker der Baugruppe abzuziehen. Zur leichteren Auffindung der Betä¬ tigungsöffnungen einer bestimmten Federkraftklemme sind die drei zugeordneten Öffnungen der jeweiligen Betätigungsrich¬ tungen A ... C mit einer einheitlichen Beschriftung versehen. Zum Öffnen gleichzeitig mehrerer Federkraftklemmen kann auch ein Spezialwerkzeug, z. B. ein Kamm oder eine Kniehebel¬ presse, verwendet werden, das so ausgelegt ist, daß die An- Schlußeinrichtung zur leichteren Verdrahtung in dieses ein¬ gespannt wird. Dabei ist es vorteilhaft, daß die Leitungen beidhändig nacheinander eingeführt und durch Entfernung des SpezialWerkzeuges gleichzeitig kontaktiert werden. Dies ist eine wesentliche Erleichterung bei der Verdrahtung. Bei den Betätigungsrichtungen A und B bleibt der Schraubendreher oder Kamm durch Selbstklemmung ohne zusätzliches Halten stecken. Dadurch können ebenfalls die externen Leitungen beidhändig bei geöffneten Federkraftklemmen montiert werden. Durch das Öffnen der Federkraftklemmen über KunstStoffhebel wird eine elektrische Kontaktierung mit dem Werkzeug vermieden und eine mechanische Überbeanspruchung der Federkraftklemmen ver- hindert. Die Aufhängung des Hebels 5 mit einem Drehgelenk sorgt dafür, daß auf die Federkraftklemme 2 lediglich eine Kraftkomponente in Biegerichtung wirkt, und vermeidet eben¬ falls Beschädigungen durch das Werkzeug. Wiring or correction can be carried out in the actuation direction A both when the connection device is plugged in, ie when it is plugged into the front connector of a printed circuit board, and when it is not connected to the basic device. Advantageously, the view of the openings for the external lines is not obstructed by a tool if this is introduced through openings in the actuation directions B or C. To do this, it is usually necessary to remove the connection device from the front connector of the module. To make it easier to find the actuation openings of a specific spring-loaded terminal, the three assigned openings of the respective actuation directions A ... C are provided with a uniform label. To open several spring-loaded terminals at the same time, a special tool, e.g. B. a comb or a toggle lever press can be used, which is designed so that the connection device is clamped in this for easier wiring. It is advantageous that the lines are inserted with both hands in succession and by removing the Special tool can be contacted at the same time. This makes the wiring much easier. With actuation directions A and B, the screwdriver or comb gets stuck due to self-locking without additional holding. This means that the external cables can also be mounted with both hands when the spring-loaded terminals are open. Opening the spring-loaded terminals using plastic levers prevents electrical contact with the tool and prevents the spring-loaded terminals from being mechanically overloaded. The suspension of the lever 5 with a swivel joint ensures that only one force component acts in the bending direction on the spring-loaded terminal 2 and also avoids damage from the tool.
