Description

Die Erfindung bezieht sich auf ein Gehäuse mit in zwei oder mehr Reihen angeordneten Anschlußklemmen, deren Einführöffnungen für die anzuschließenden elektrischen Leitungen an einer Gehäuse­seite liegen und deren zugehörige Kontaktanschlußschrauben an einer rechtwinklig hierzu befindlichen Gehäuseseite zugänglich sind, wobei die Klemmen der Anschlußklemmenreihen stufenweise versetzt sind.The invention relates to a housing with terminals arranged in two or more rows, the insertion openings for the electrical lines to be connected are located on one side of the housing and the associated contact connection screws are accessible on a side of the housing at right angles thereto, the terminals of the terminal rows being offset in steps.

Gehäuse mit Anschlußklemmen der vorgenannten Art sind aus der DE-PS 27 32 63 bekannt. Das hier beschriebene Gehäuse ist das eines Schützes. Sein Kontaktsystem weist seitlich gekröpfte Kontaktschienen auf, die in zwei seitlich versetzten Ebenen ange­ordnet sind. Bei Draufsicht liegen die Kontaktanschlußschrauben einer Anschlußklemmenstufe mittig zu denen der anderen Stufe. Auf einer Anschlußklemmenstufe befindet sich eine Anschlußklemme weniger als auf der anderen Stufe.Housing with terminals of the aforementioned type are known from DE-PS 27 32 63. The housing described here is that of a contactor. His contact system has laterally cranked contact rails, which are arranged in two laterally offset planes. When viewed from above, the contact connection screws of one connection terminal stage are centered on those of the other stage. There is one connection terminal less on one terminal stage than on the other stage.

Bei Reihenklemmen ist es gemäß FR-A-1 597 216 auch bekannt, die Verbindungsschiene zweier Klemmpunkte zur Freilassung der Schraubenköpfe anderer Klemmpunkte um diese oberhalb der Schraubenköpfe und bogenförmig herumzuführen.In the case of terminal blocks, it is also known according to FR-A-1 597 216 to guide the connecting rail of two clamping points to release the screw heads of other clamping points around them above the screw heads and in an arc.

Der Erfindung liegt die Aufgabe zugrunde, ein Gehäuse mit einer möglichst großen Anzahl von Geräteanschlußklemmen zu schaffen, wobei, wie beim Stand der Technik, der freie Zugang zu den Kon­taktanschlußschrauben bei der Verdrahtung in beliebiger Reihen­folge erhalten bleiben soll.The invention has for its object to provide a housing with as large a number of device connection terminals as possible, as in the prior art, the free access to the contact connection screws should be retained in the wiring in any order.

Diese Aufgabe wird bei einer Anordnung der obengenannten Art dadurch gelöst, daß die Anschlußklemmen der Stufe, die der Gehäuseseite mit dem Zugang zu den Einführöffnungen der An­schlußklemmen näher liegt, auch den kürzeren Abstand zu der Gehäuseseite besitzt, an der die Kontaktanschlußschrauben zugänglich sind, und daß zumindest ein Teil der Anschlußklem­men auf der den Kontaktanschlußschrauben abgewandten Seite mit einer elektrischen Klemmableitung versehen ist, die an den Einführöffnungen einer anderen Anschlußklemmenreihe vor­bei isoliert geführt sind.This object is achieved in an arrangement of the type mentioned above in that the connecting terminals of the step, which is closer to the housing side with access to the insertion openings of the connecting terminals, also the shorter distance to the Has housing side, on which the contact terminal screws are accessible, and that at least some of the terminals on the side facing away from the contact terminal screws are provided with an electrical terminal lead, which are guided past the insertion openings of another row of terminals isolated.

Aus der FR-A-1 464 021 ist ein Klemmblock nach Art von Rei­henklemmen bekannt, bei dem jedoch das Problem, die Klemm­ableitungen einiger Klemmen an den anderen Klemmen vorbeizu­führen, nicht auftritt.From FR-A-1 464 021 a terminal block in the manner of terminal blocks is known, but in which the problem of leading the terminal leads of some terminals past the other terminals does not arise.

Durch den Gegenstand der Erfindung ist es möglich, die anzu­klemmenden elektrischen Leitungen nicht nur senkrecht, sondern auch schräg in die Gehäuseöffnungen einzuführen. Weiterhin er­laubt die besondere Gestaltung des Gehäuses, daß elektrische An­schlußleitungen verschiedener Drahtstärken in beliebiger Reihen­folge und ohne gegenseitige Behinderung beim Festdrehen oder Lösen der Kontaktanschlußschrauben verwendet werden können. Den Kontaktanschlußschrauben sind an der Gehäusefrontseite Schrau­bendreheröffnungen in einer Ebene zugeordnet, wodurch der Schraubendreher beim Festdrehen und Lösen der Kontaktanschluß­schrauben besser geführt und diese Tätigkeit einfacher und schneller erledigt werden kann. Den Einführöffnungen der An­schlußklemmen sind trichterförmige Gehäuseöffnungen vorgelagert, um das Einführen der anzuklemmenden Leitungen zu erleichtern. Das Druckstück der Anschlußklemme läuft auf der den Kontaktan­schlußschrauben abgewandten Seite in eine Klemmableitung aus, mit der die Anschlußklemme in einfacher Weise im Gehäuse be­festigt wird. Das Druckstück der Anschlußklemme besitzt im Be­reich der Klemmableitung ein federndes Klemmelement, das aus einem Längsschlitz in der Klemmableitung sowie nasenförmigen Ausbuchtungen an der Klemmableitung besteht, womit die Befesti­gung der Anschlußklemme durch Hineinstecken in den Gehäuse­schlitz am Boden der Ausnehmung leicht erfolgen kann. Die An­schlußklemmen sind als Rahmenklemmen ausgeführt, die sich durch ein leichtes Anklemmen der elektrischen Leitungen bewährt haben. Das Druckstück der Rahmenklemme ist U-förmig zur Kontaktan­schlußschraube hin gebogen und der freie Schenkel des U-förmi­gen Druckstücks weist einen Schlitz auf, in den eine Nut der Kontaktanschlußschraube einklemmbar ist. Die Kontaktanschluß­schraube verbindet somit auf einfache Weise das Druckstück mit dem Rahmen der Anschlußklemme. Die Verbindung verhindert eine gegenseitige Verschiebung der Einzelteile der Anschlußklemme, was eine einfachere und schnellere Montage im Gehäuse ermög­licht. Die Klemmableitung des Druckstücks der Rahmenklemmen läuft als elektrisch leitende Anschlußschiene aus, so daß sich die elektrische Verbindung mit der weiteren Verdrahtung der im Gehäuse befindlichen elektrischen Geräte auf einfache Weise wahlweise als Steck- oder Lötanschluß vornehmen läßt. An die Schraubendreheröffnungen schließen sich erweiterte Ausnehmungen an, in die die Rahmenklemmen leicht hineingeschoben werden kön­nen. In den Begrenzungswänden zumindest eines Teils der Gehäuse­öffnungen sind Schlitze im Gehäuse als Fortführung der Ausneh­mungen vorgesehen, die im wesentlichen parallel zur Achse der Kontaktanschlußschrauben verlaufen. In diesen Schlitzen können die Klemmableitungen von einem Teil der Rahmenklemmen einfach geführt werden. Dadurch ist die bezeichnete Isolierung gegen­über benachbarten Anschlußleitungen in besonders günstiger Weise gegeben. An der Bodenseite der Ausnehmungen für eine An­schlußklemmenreihe sind im Gehäuse in Längsrichtung der Kon­taktanschlußschrauben Längsschlitze vorgesehen, in denen die Klemmableitungen vorteilhaft geführt werden. An der Gehäuse­frontseite ist eine abnehmbare Abdeckplatte mit den Schrauben­dreheröffnungen vorgesehen, die den Ausnehmungen im Gehäuseober­teil zur Aufnahme der Anschlußklemmen gegenüberliegen. Durch die Bauart können die Rahmenklemmen in die Ausnehmungen leicht eingeführt und festgeklemmt werden. Außerdem ist es möglich, bei abgenommener Abdeckplatte die Montage der Anschlußklemmen im Gehäuse zu automatisieren.The subject matter of the invention makes it possible not only to insert the electrical lines to be clamped vertically but also obliquely into the housing openings. Furthermore, the special design of the housing allows electrical connecting lines of different wire thicknesses to be used in any order and without mutual hindrance when tightening or loosening the contact connection screws. The contact connection screws are assigned on the front side of the screwdriver openings in one plane, as a result of which the screwdriver is better guided when tightening and loosening the contact connection screws and this task can be carried out more easily and quickly. Funnel-shaped housing openings are placed in front of the insertion openings of the connection terminals in order to facilitate the insertion of the lines to be connected. The pressure piece of the connection terminal runs out on the side facing away from the contact connection screws into a clamp derivation with which the connection terminal is fastened in a simple manner in the housing. The pressure piece of the connecting terminal has a resilient clamping element in the area of the terminal lead, which consists of a longitudinal slot in the terminal lead and lug-shaped protrusions on the terminal lead, so that the terminal can be easily attached by inserting it into the housing slot at the bottom of the recess. The connection terminals are designed as box terminals, which are characterized by easy connection of the electrical cables has proven itself. The pressure piece of the box clamp is bent in a U-shape towards the contact connection screw and the free leg of the U-shaped pressure piece has a slot into which a groove of the contact connection screw can be clamped. The contact connecting screw thus connects the pressure piece to the frame of the connecting terminal in a simple manner. The connection prevents mutual displacement of the individual parts of the connection terminal, which enables easier and faster assembly in the housing.

In the boundary walls of at least some of the housing openings, slots are provided in the housing as a continuation of the recesses, which run essentially parallel to the axis of the contact connection screws. Part of the box terminals can be used to easily guide the clamp leads in these slots. As a result, the designated insulation from adjacent connecting lines is provided in a particularly favorable manner. On the bottom side of the recesses for a row of terminals, longitudinal slots are provided in the housing in the longitudinal direction of the contact terminal screws, in which the terminal leads are advantageously guided. On the front of the housing there is a removable cover plate with the screwdriver openings, which lie opposite the recesses in the upper part of the housing for receiving the connection terminals. Due to the design, the box clamps can be easily inserted into the recesses and clamped in place. It is also possible to automate the assembly of the terminals in the housing with the cover plate removed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das im folgenden näher beschrieben ist.In the drawing, an embodiment of the invention is shown, which is described in more detail below.

Das Gehäuse besteht aus einem Oberteil 1 mit einer an seiner Frontseite abnehmbaren Abdeckplatte 2, wie in FIG 1 darge­gestellt, und einem nicht dargestellten Unterteil. Das aus Kunststoff gegossene Gehäuse hat eine Baubreite von z.B. 22,5 mm und dient zum Einbau für elektromechanische und elek­tronische Geräte. An den Schmalseiten des Gehäuseoberteils 1 befinden sich die Anschlußklemmen 4, die in zwei Reihen stu­fenweise versetzt angeordnet sind. Jede Anschlußklemmenreihe ist mit drei Anschlußklemmen versehen.The housing consists of an upper part 1 with a removable cover plate 2 on its front side, as shown in FIG 1, and a lower part, not shown. The housing cast from plastic has a width of e.g. 22.5 mm and is used for installation for electromechanical and electronic devices. On the narrow sides of the upper housing part 1 there are the connecting terminals 4, which are staggered in two rows. Each row of terminals is provided with three terminals.

FIG 2 zeigt den Schnitt im Bereich einer Schmalseite. Zur Frontseite hin hat das Gehäuseoberteil 1 Ausnehmungen 14, in denen die Anschlußklemmen 4 stecken. Die Ausnehmungen 14 der beiden Anschlußklemmenreihen sind wegen der stufenweisen Ver­setzung unterschiedlich tief. Um die elektrischen Leitungen leicht und schnell anzuklemmen, sind an den Schmalseiten des Gehäuseoberteils 1 trichterförmige Gehäuseöffnungen 15 vorge­sehen. Die Gehäuseöffnungen 15 sind in zwei Reihen übereinan­der angeordnet, wobei jeder jeweils eine Anschlußklemmenreihe zugeordnet ist. Die tiefere Ausnehmung 14 der beiden Anschluß­klemmenreihen geht an ihrem Boden in einen Längsschlitz 17 im Gehäuse über, wogegen die Ausnehmung 14 der anderen Anschluß­klemmenreihe in einen ähnlich dem Längsschlitz 17 ausgeführten Schlitz 16 im Gehäuse mündet, der sich nach FIG 3 in einer Begrenzungswand seitlich einer Gehäuseöffnung 15 befindet, die zu der Anschlußklemmenreihe mit dem größeren Abstand zur Gehäu­sefrontseite gehört.2 shows the section in the region of a narrow side. Towards the front, the upper housing part 1 has recesses 14 in which the connecting terminals 4 are inserted. The recesses 14 of the two rows of terminals are of different depths because of the gradual offset. In order to clamp the electrical lines easily and quickly, funnel-shaped housing openings 15 are provided on the narrow sides of the upper housing part 1. The housing openings 15 are arranged in two rows one above the other, each being assigned a row of terminals. At its bottom, the deeper recess 14 of the two rows of terminals merges into a longitudinal slot 17 in the housing, whereas the recess 14 of the other row of terminals opens into a slot 16 in the housing which is similar to the longitudinal slot 17 and which, according to FIG. 3, is located in a boundary wall to the side of a housing opening 15 is located belongs to the row of terminals with the greater distance to the front of the housing.

Die Rahmenklemmen 4 der beiden Anschlußklemmenreihen sind unter­schiedlich ausgeführt. Sie bestehen nach FIG 4 aus dem Rahmen 12, der Kontaktanschlußschraube 5, die für die beiden Anschlußklem­menreihen entsprechend der stufenweisen Versetzung unterschied­lich lang ist, sowie dem auch für beide Anschlußklemmenreihen unterschiedlich ausgeführten Druckstück 6. Die größere Länge der Kontaktanschlußschrauben 5 einer Anschlußklemmenreihe bie­tet den Vorteil, daß die Schraubenköpfe gleich nahe zu den Schraubendreheröffnungen liegen wie bei den kürzeren Kontakt­anschlußschrauben 5 und daher der Schraubendreher beim Fest­drehen und Lösen sämtlicher Kontaktanschlußschrauben 5 in gleicher Weise gut geführt ist. Die Kontaktanschlußschraube 5 liegt mit ihrem Schraubgewinde, das durch eine Seite des Rahmens 12 geschraubt ist, auf dem eigentlichen Druckstück 6 auf. Die Kontaktanschlußschraube 5 ist mit ihrer Nut im Schlitz des freien Schenkels 7 gehalten, der sich durch U-förmiges Umbiegen des eigentlichen Druckstücks 6 zur Kon­taktanschlußschraube 5 hin ergibt. Durch diese Verbindung wird erreicht, daß sich der Rahmen 12 und das eigentliche Druckstück 6 bei Verdrehen der Kontaktanschlußschraube 5 gegeneinander bewegen und zwischen beiden die Anschlußleitung geklemmt werden kann. Das eigentliche Druckstück 6 hat eine rechtwinkelige Fortsetzung zu der dem freien Schenkel 7 abge­wandten Seite hin, die einen Absatz 8 aufweist, an den sich die als schmale Kontaktschiene ausgeführte Klemmableitung 9 an­schließt. Das Druckstück 6 der in der tieferen Ausnehmung 14 liegenden Rahmenklemme 4 besitzt eine Klemmableitung 9, die ge­genüber dem jenseits des Absatzes 8 liegenden Teil des Druck­stücks 6 unverdreht weiterläuft. Die Klemmableitung 9 dieser Rahmenklemme weist einen schmalen Schlitz 10 auf, der sich über den Absatz 8 hinaus bis zum eigentlichen Druckstück 6 fortsetzt. Nahe dem Absatz 8 finden sich an der Klemmablei­tung 9 seitlich zwei nasenförmige Ausbuchtungen 11, die nach Einschub der Klemmableitung 9 in den Schlitz 16 im Gehäuse hinter Kanten des Schlitzes 16 verrasten. Damit ist die Rah­menklemme 4 in der tieferen Ausnehmung 14 über das Druckstück 6 befestigt. Von der soweit beschriebenen Ausführung des Druck­stücks 6 unterscheidet sich das betrachtete Druckstück 6 für die Rahmenklemme 4 der benachbarten Anschlußklemmenreihe. Zwar sieht dieses Druckstück 6 vom geschlitzten Schenkel 7 bis hin zum Absatz 8 gleich aus wie das zuvor beschriebene, doch be­steht vom Absatz 8 an eine abweichende Fortsetzung der Klemm­ableitung 9. Das hier betrachtete Druckstück 6 geht am Absatz 8 in eine als schmale Kontaktschiene ausgeführte Klemmablei­tung 9 über, die gegenüber der anderen Ausführung mit ihrer Längsachse zum jenseits des Absatzes 8 liegenden Teil des Druckstücks 6 in einer um 90° versetzten Ebene verläuft. Zur Befestigung der Rahmenklemme 4 ist wie zuvor ein federndes Klemmelement an der Klemmableitung vorgesehen. Es besteht wiederum aus einem Längsschlitz 10 in der Kontaktschiene sowie zwei seitlich an dieser befindlichen nasenförmigen Aus­buchtungen 11. Die Befestigung der Rahmenklemme 4 erfolgt auch durch das federnde Klemmelement an der Klemmableitung 9, die aber abweichend von der benachbarten Anschlußklemmenreihe im Schlitz 16 im Gehäuse einer die Gehäuseöffnung 15 begren­zenden Wand festgeklemmt ist. Die die Klemmableitungen 9 bil­denden schmalen Kontaktschienen beider Ausführungsformen sind derart geformt, daß an ihrem freien Ende wahlweise ein Steck­oder Lötanschluß möglich ist. Um den elektrischen Anschluß der im Gehäuse befindlichen Geräte in leichter Weise vornehmen zu können, ist das Gehäuseoberteil 1 vom Unterteil abnehmbar, so daß ein freier Zugang zu den Kontaktschienen besteht. Außerdem bietet sich durch die Gehäusegestaltung vorteilhaft an, nach Entfernen der Abdeckplatte 2 die Rahmenklemmen 4 mit­tels Automaten in die Ausnehmungen 14 einzuschieben und zu verrasten.The box terminals 4 of the two rows of terminals are designed differently. According to FIG. 4, they consist of the frame 12, the contact connecting screw 5, which has a different length for the two rows of connecting terminals, depending on the gradual offset, and the pressure piece 6, which is also designed differently for the two connecting terminal rows. The greater length of the contact connecting screws 5 of a connecting terminal row offers the advantage that that the screw heads are just as close to the screwdriver openings as for the shorter contact connection screws 5 and therefore the screwdriver is well guided in the same way when tightening and loosening all contact connection screws 5. The contact terminal screw 5 lies with its screw thread, which is screwed through one side of the frame 12, on the actual pressure piece 6. The contact terminal screw 5 is held with its groove in the slot of the free leg 7, which results from the U-shaped bending of the actual pressure piece 6 to the contact terminal screw 5. This connection ensures that the frame 12 and the actual pressure piece 6 move against each other when the contact terminal screw 5 is rotated and the connecting line can be clamped between the two. The actual pressure piece 6 has a right-angled continuation to the side facing away from the free leg 7, which has a shoulder 8, to which the clamp lead 9 designed as a narrow contact rail connects. The pressure piece 6 of the frame clamp 4 located in the deeper recess 14 has a clamping lead 9 which continues to run untwisted with respect to the part of the pressure piece 6 lying beyond the shoulder 8. The clamp lead 9 of this box clamp has a narrow slot 10, which continues beyond the paragraph 8 to the actual pressure piece 6. Near the paragraph 8 there are two nose-shaped bulges 11 on the side of the clamping lead 9, which follow Lock the insertion of the clamp lead 9 into the slot 16 in the housing behind the edges of the slot 16. The frame clamp 4 is thus fastened in the deeper recess 14 via the pressure piece 6. From the design of the pressure piece 6 described so far, the pressure piece 6 under consideration for the box terminal 4 of the adjacent terminal row differs. Although this pressure piece 6 looks the same from the slotted leg 7 up to the paragraph 8 as described above, there is a different continuation of the clamping lead 9 from the paragraph 8. The pressure piece 6 considered here goes on the paragraph 8 into a terminal lead designed as a narrow contact rail 9, which, in relation to the other embodiment, runs with its longitudinal axis to the part of the pressure piece 6 lying beyond the shoulder 8 in a plane offset by 90 °. To fasten the frame clamp 4, a resilient clamping element is provided on the clamp lead as before. It consists in turn of a longitudinal slot 10 in the contact rail and two laterally located on this nose-shaped bulges 11. The attachment of the frame clamp 4 is also carried out by the resilient clamping element on the terminal lead 9, but which deviates from the adjacent row of terminals in the slot 16 in the housing one Housing opening 15 bounding wall is clamped. The narrow contact rails forming the clamping leads 9 of both embodiments are shaped such that a plug or solder connection is optionally possible at their free end. In order to make the electrical connection of the devices located in the housing in a simple manner, the upper housing part 1 can be removed from the lower part, so that there is free access to the contact rails. In addition, the housing design advantageously offers that, after the cover plate 2 has been removed, the box terminals 4 are inserted and locked into the recesses 14 by means of automatic machines.
