Description

Die Erfindung betrifft ein Modul nach dem Oberbegriff des Anspruches 1.The invention relates to a module according to the preamble of claim 1.

Module wie Reihenklemmen sind in verschiedensten Bauformen bekannt. Im Bereich des Automatisierungstechnik werden in neuerer Zeit vermehrt reihenklemmenartige Modulscheiben eingesetzt, welche an ein Gateway angerastet werden. Diese Modulscheiben sind im Grunde Reihenklemmenabwandlungen, die auf einer Tragschiene zu einem elektrischen Gerät zusammengerastet werden. Ein derartiges, aus Modulscheiben bzw. Reihenklemmelementen zusammengesetztes, elektrisches Gerät ist aus der EP 95 113 730 A1 bekannt. Bei dem in dieser Schrift gezeigten Gerät mit internem Busleiter dienen auf Tragschienen anreihbare Anschlußblocks zur Signalanpassung zwischen einem übergeordneten Feldbus und an die Anschlußblocks angeschlossenen Initiatoren, Feldgeräten oder dergleichen. Die Anschlußblocks sind aus funktionsverschiedenen Anschluß- bzw. Modulscheiben (Reihenklemmen) zusammengesetzt, wobei zwischen Schutzleiterscheiben, Einspeisescheiben, Versorgungs/Signalleiterscheiben und Rastfußscheiben unterschieden wird. Ein oder mehrere Anschlußblocks sind über den internen Busleiter mit einem Anschlußmodul für einen Feldbus verbindbar. Modules such as terminal blocks are known in various designs. In the area automation technology are more and more terminal-like Module disks are used, which are snapped onto a gateway. These module disks are basically modular terminal modifications that are on a mounting rail too an electrical device. One of these, made of modular disks or modular terminal elements assembled electrical device is from the EP 95 113 730 A1 known. In the device shown in this document with an internal Bus conductors are used for connection blocks that can be arranged on mounting rails for signal adaptation between a higher-level fieldbus and connected to the connection blocks Initiators, field devices or the like. The connection blocks are made of different functions Connection or module disks (terminal blocks) assembled, whereby between protective conductor washers, feed washers, supply / signal conductor washers and locking foot washers is distinguished. One or more connection blocks are via the internal bus conductor with a connection module for one Fieldbus connectable.

Dieses elektrische Gerät hat sich zwar an sich bewährt. Damit aneinandergereihte Module wie Reihenklemmen oder Modulscheiben ohne ein sie übergreifendes Gehäuse auf einer Tragschiene nicht unbeabsichtigt auseinanderdriften (z.B. infolge Rüttelbewegungen einer Maschine) ist es nötig, die Modulscheiben durch geeignete Koppelelemente aneinanderzukoppeln. Aufgrund der typischen Raumenge am Einbauort ist es besonders problematisch, wenn die Reihenklemme keinen Raum zur Betätigung des Koppelelementes bietet.This electrical device has proven itself. Modules strung together such as terminal blocks or modular disks without a housing that spans them Do not accidentally drift apart on a mounting rail (e.g. as a result of shaking movements a machine), it is necessary to connect the module disks with suitable coupling elements to couple to each other. Because of the typical space at the installation location, it is particularly problematic if the terminal block has no space for operating the Coupling element offers.

An dieser Stelle setzt die Erfindung mit der Aufgabe an, bei einem gattungsgemäßen Modul wenigstens eines der Paare zusammenwirkender Koppelelemente derart auszugestalten, daß die Module auch ohne ein Betätigungswerkzeug von der Nachbarklemme gelöst werden können. Dabei soll selbstverständlich weiterhin sichergestellt sein, daß auch diese Reihenklemmen nicht zu leicht voneinander gelöst werden können.At this point, the invention starts with the task of a generic To design the module of at least one of the pairs of interacting coupling elements in such a way that the modules can be removed from the adjacent terminal without an operating tool can be solved. Of course, it should continue to be ensured that these terminal blocks can not be easily separated from each other.

Dieses Problem löst die Erfindung durch den Gegenstand des Anspruches 1. Anders als beim Stand der Technik sind danach zwei benachbarte Module/Reihenklemmen auf der Tragschiene allein durch Aufheben der Parallelität, beispielsweise durch Verdrehen der Module gegeneinander voneinander lösbar. Dadurch ist es möglich die Module ohne jedes Werkzeug voneinander zu lösen, beispielsweise auch derart, daß die Entriegelung von zwei aneinandergereihten Modulen durch eine Betätigung des einen Moduls an einem eine Betätigungspunkt beabstandet vom Koppelelement erfolgt.The invention solves this problem by the subject matter of claim 1 than in the prior art, there are two adjacent modules / terminal blocks the mounting rail only by removing the parallelism, for example by twisting the modules can be detached from each other. This makes the modules possible without detaching each tool, for example also in such a way that the release of two modules lined up by actuating one Module at an actuation point spaced from the coupling element.

Vorzugsweise ist das erste Koppelelement ein Rasthaken und das zweite Koppelelement eine zum Rasthaken korrespondierende Rastöffnung, wobei diese Elemente derart ineinandergreifen, daß der Rasthaken allein durch ein Verdrehen der zusammengerasteteten Reihenklemmen aus der Rastöffnung gelöst wird. The first coupling element is preferably a latching hook and the second coupling element a locking opening corresponding to the locking hook, these elements being such interlock that the locking hook alone by twisting the locked together Terminal blocks is released from the locking opening.

Fig. 1 zeigt Basis-Klemmenträger 2 für Reihenklemmen bzw. Module bzw. Modulscheiben, welche mit weiteren Modulscheiben und/oder Modulblöcken auf einer Tragschiene 3 zu einem Anschlußblock variabler Länge zusammenfügbar sind. Der Basis-Klemmenträger 2 ist mit Kunststoff-Rastfüßen 4 versehen (siehe Fig. 2), mit denen in an sich bekannter Weise eine Rastverbindung zur Tragschiene 3 herstellbar ist. 1 shows basic terminal supports 2 for terminal blocks or modules or module disks, which with further module disks and / or module blocks on one Carrier rail 3 can be assembled into a terminal block of variable length. The Basic terminal support 2 is provided with plastic locking feet 4 (see Fig. 2), with which can produce a snap-in connection to the mounting rail 3 in a manner known per se is.

Der Basis-Klemmenträger 2 weist einen unteren Basisabschnitt 6 auf; welcher sich in einen Bereich oberhalb der Tragschienenfüße 4 und neben den Tragschienenfüßen 4 beidseits seitlich über die Tragschiene 3 hinaus erstreckt. In dem Basisabschnitt 6 ist in dem einen von der Tragschiene 3 abgewandt liegenden Außenbereich eine den Basis-Klemmenträger 2 senkrecht zu seiner Haupt-Erstreckungsebene durchdringende Busleiteröffnung 8 zur Aufnahme des internen Busleiterabschnitts vorgesehen, der eine Weiterleitung der Busleitersignale von Einzelmodul zu Einzelmodul und in eine Elektronikleiterplatte (hier nicht dargestellt) erlaubt. Zur Aufhahme der Elektronik-Leiterplatte nebst ihrem (hier ebenfalls nicht dargestellten) Gehäuse ist in dem Bereich, welcher sich ungefähr von der Senkrechten zur (axialen) Mittellinie 10 der Tragschiene bis zu dem internen Busleiterabschnitt (hier ebenfalls nicht dargestellt) erstreckt, in dem Basis-Klemmenträger 2 eine Umfangs-Ausnehmung 12 ausgebildet, die an der Außenseite der Reihenklemme von einem Steg 14 begrenzt wird.The base clamp support 2 has a lower base section 6; which is in an area above the mounting rail feet 4 and next to the mounting rail feet 4 extends laterally on both sides beyond the mounting rail 3. In the base section 6 is in one the outer terminal area facing away from the mounting rail 3 is the basic terminal support 2 bus conductor opening penetrating perpendicular to its main extension plane 8 provided for receiving the internal bus conductor section, the one Forwarding of the bus conductor signals from single module to single module and into an electronic circuit board (not shown here) allowed. To accommodate the electronic circuit board in addition to its housing (also not shown here) is in the area which is approximately from the perpendicular to the (axial) center line 10 of the DIN rail up to the internal bus conductor section (also not shown here) extends, in the base terminal support 2 a circumferential recess 12 is formed, which is delimited on the outside of the terminal block by a web 14.

Ungefähr an dem der Ausnehmung 12 gegenüberliegenden Ende des Basis-Klemmenträgers 2 ist an den Basisabschnitt 6 ein senkrecht nach oben vorstehender Anschlußabschnitt 16 angeformt, der mit den sechs in zwei Reihen zu je drei angeordneten Anschlüssen A1, A2, B1, B2, C1, C2 versehen ist. Öffnungen 18 mit quadratischem Querschnitt neben Anschlußöffnungen 32 für die Anschlüsse A1, A2, B1, B2 ... erlauben das Einführen eines Schraubendrehers zum Öffnen der im Anschlußabschnitt angeordneten Kontaktelemente (nicht dargestellt).Approximately at the end of the base terminal support opposite the recess 12 2 is a protruding vertically upward on the base section 6 Connection section 16 formed, the six arranged in two rows of three Connections A1, A2, B1, B2, C1, C2 is provided. Openings 18 with a square Cross section next to connection openings 32 for connections A1, A2, B1, B2 ... allow the insertion of a screwdriver to open the in the connection section arranged contact elements (not shown).

Die Einzel- und Doppelanschlüsse A1, A2, B1, B2 sind über (hier nicht dargestellte Stromschienen) im Basis-Klemmenträger 2 mit Anschlüssen 20 verbunden, welche mit der Leiterplatte verbindbar sind. Öffnungen 22 dienen zur Durchführung einer elektrisch leitenden Verbindung zwischen der Leiterplatte oder einem Stecker und Querbrücker-Stromführungen (hier ebenfalls nicht dargestellt) zwischen benachbarten Basis-Klemmenträgern 2. The single and double connections A1, A2, B1, B2 are via (not shown here Busbars) in the base terminal support 2 with connections 20, which with the circuit board are connectable. Openings 22 are used to carry out an electrical conductive connection between the printed circuit board or a plug and cross jumper current leads (also not shown here) between adjacent base terminal supports 2nd

Neben der Weiterführung eines Bussystemes von Modulscheibe zu Modulscheibe bzw. von Basis-Klemmenträger 2 zu Basis-Klemmenträger 2 erfolgt auch die Weitergabe von Potentialen bzw. eine Querbrückung von Potentialen zwischen benachbarten Modulscheiben. Es ist daher von großem Vorteil, daß die benachbarten Basis-Klemmenträger fest aneinanderrastbar sind, derart, daß sie sich beispielsweise auch bei Rüttelbeanspruchungen an Maschinensteuerungen nicht ungewollt voneinander lösen. Um stets eine sichere Kontaktierung zwischen den benachbarten Basis-Klemmenträgern 2 sicherzustellen, sind diese mit verschiedenen Führungs- und/oder Koppelelementen versehen. Deren Anordnung und Funktion wird nachfolgend näher erläutert.In addition to the continuation of a bus system from module pane to module pane or from base terminal support 2 to base terminal support 2, the transfer also takes place of potentials or a cross-bridging of potentials between neighboring ones Modular discs. It is therefore of great advantage that the adjacent base clamp supports are firmly snapped together, in such a way that they also, for example, at Do not unintentionally release vibrations on machine controls. To always ensure reliable contact between the neighboring base terminal blocks 2 ensure that these are with different leadership and / or Provide coupling elements. Their arrangement and function is explained in more detail below explained.

Zunächst weist jeder Basis-Klemmenträger 2 an einer seiner beiden aneinanderzureihenden Außenflächen Führungszapfen 24 auf, die sich vom Basis-Klemmenträger 2 weg zur Spitze hin etwas verjüngen und die im wesentlichen auf den Außenflächen der Basis-Klemmenträger 2 senkrecht stehen. Diese Führungszapfen 24 sind dazu ausgelegt, beim Zusammenführen zweier benachbarter Basis-Klemmenträger 2 in Ausnehmungen bzw. Öffnungen 26 eines benachbarten Basis-Klemmenträgers 2 einzugreifen. Sie erleichtern das Zusammenführen der Basis-Klemmenträger 2 und gewährleisten, daß die Basis-Klemmenträger 2 in definierter Stellung aneinanderliegen. Ein Abschnitt 28 dient ebenfalls zum Eingriff in eine entsprechende Profilausnehmung. Er deckt unter anderem die (nicht dargestellten) Querbrücker-Stromschienenstücke ab, die zur Kontaktierung entsprechend ausgeformter Buchsenelemente an der der Außenseite A zugewandten Außenseite B der Nachbarklemme dienen.First, each base terminal support 2 points to one of its two to be strung together Outside surfaces guide pin 24, which is from the base terminal support 2nd slightly taper away towards the top and essentially on the outer surfaces of the Stand the basic terminal support 2 vertically. These guide pins 24 are designed to when merging two adjacent base terminal supports 2 into recesses or to engage openings 26 of an adjacent base terminal support 2. They facilitate the merging of the basic terminal supports 2 and ensure that the base terminal supports 2 lie against each other in a defined position. A section 28 also serves to engage in a corresponding profile recess. It covers under other from the (not shown) cross-bridge busbar pieces from the Contacting correspondingly shaped socket elements on the outside A serve outside B of the adjacent terminal.

Während die Führungszapfen 24 dafür sorgen, daß die Konturen der benachbarten Klemmen genau aneinanderliegen, stellen zusätzliche Koppelelemente sicher, daß die benachbarten Basis-Klemmenträger 2 auf der Tragschiene 3 fest zusammenrasten und nicht unbeabsichtigt auseinandergezogen werden können. Diese Koppelelemente sind als zwei Rasthaken 30, 32 mit Rasthakenköpfen 34, 36 ausgebildet, mit denen sie jeweils in eine entsprechend ausgebildete Ausnehmung 38, 40 des benachbarten Basis-Klemmenträgers 2 eingreifen und Rastkanten 42, 44 in diesen Ausnehmungen 38, 40 hinterfassen.While the guide pin 24 ensure that the contours of the neighboring Clamps lie exactly next to each other, additional coupling elements ensure that the the adjacent base terminal support 2 firmly snap together on the mounting rail 3 and cannot be pulled apart unintentionally. These are coupling elements formed as two locking hooks 30, 32 with locking hook heads 34, 36 with which they each in a correspondingly formed recess 38, 40 of the adjacent base terminal support 2 engage and locking edges 42, 44 in these recesses 38, 40th leave behind.

Der erste Rasthaken 30 steht (siehe Fig. 3 - 7) im wesentlichen senkrecht vom Basis-Klemmenträger 2 ab. Er setzt an einer Mittelwandung 46 des Basis-Klemmenträgers 2 an und erstreckt sich soweit in die Ausnehmung 28 der Nachbarklemme bzw. des Nachbar-Basis-Klemmenträgers, daß er gerade die Außenwandung 48 der Nachbarklemme hintergreifen kann. Dadurch, daß der Rasthakenkopf 34 an seinem vom Basis-Klemmenträger 2 abgewandten axialen Ende eine Führungsspitze 50 aufweist, wird der Rasthaken 30 beim Zusammenführen der beiden aneinander liegenden Basis-Klemmenträger relativ leicht in die Öffnung 38 eingeführt. Gelöst wird der Rasthaken 30 durch eine in der unteren Wandung der Ausnehmung 12 ausgebildete Öffnung 52 bei abgenommener Elektronik von oben mit einem Betätigungswerkzeug (z.B. Schraubendreher).The first latching hook 30 is (see FIGS. 3-7) essentially perpendicular to the base terminal support 2 from. It is seated on a central wall 46 of the base terminal support 2 and extends as far into the recess 28 of the adjacent terminal or Neighbor base terminal support that he just the outer wall 48 of the adjacent terminal can reach behind. The fact that the locking hook head 34 on his from the base terminal support 2 has a guide tip 50 facing away from the axial end the locking hook 30 when merging the two adjacent base terminal supports inserted relatively easily into opening 38. The locking hook is released 30 through an opening 52 formed in the lower wall of the recess 12 with electronics removed from above with an operating tool (e.g. Screwdriver).

Bei kürzeren Klemmen reicht dieser Rasthaken 30 nebst zugeordneter Öffnung 34 u.U. bereits dazu aus, die Verrastung der aneinanderliegenden Basis-Klemmenträger 2 sicherzustellen. Erstrecken sich die Basis-Klemmenträger 2 aber relativ weit über den Rand der Tragschiene 3 hinaus - wenn sie beispielsweise mehr als drei Anschlußebenen aufweisen - wird eine weitere Rasthakenverbindung erforderlich. Im vorliegenden Fall sollte diese Rasthakenverbindung im Bereich der Anschlüsse A1, A2, B1, B2 , ... liegen. Da unter diesen Anschlüssen jeweils Stromschienen verlaufen, ist es anders als im Bereich der Öffnung 52 nicht möglich, eine Betätigung des Rasthakens 32 von oben mit einem Betätigungswerkzeug zu realisieren. In the case of shorter clamps, this latching hook 30 and the associated opening 34 may be sufficient. already out to ensure the locking of the adjacent base terminal supports 2. However, the basic terminal supports 2 extend relatively far beyond the Edge of the mounting rail 3 also - if, for example, more than three connection levels have - a further locking hook connection is required. In the present In this case, this snap hook connection should be in the area of connections A1, A2, B1, B2, ... lie. Since there are busbars under each of these connections, it is different from not possible in the area of the opening 52, an actuation of the locking hook 32 by to be realized with an operating tool at the top.

An dieser Stelle setzt die Erfindung mit dem Gedanken an, einen der Rasthaken 32 derart auszugestalten, daß er auch ohne ein Betätigungswerkzeug von der Nachbarklemme gelöst werden kann. Dabei soll selbstverständlich weiterhin sichergestellt sein, daß auch dieser Rasthaken 32 nicht versehentlich von der Nachbarklemme gelöst werden kann. Dies Problem löst die Erfindung dadurch, daß der zusätzliche Rasthaken 32 derart ausgebildet wird, daß der Rasthaken 32 mit der Rastausnehmung 40 der Nachbarklemme bzw. des Nachbar-Basis-Klemmenträgers 2 derart zusammenwirkt, daß die benachbarte Basis-Klemmenträger 2 auf der Tragschiene 3 durch ein Auseinanderdrehen der Reihenklemmen voneinander lösbar sind. Nach dem Ausführungsbeispiel erfolgt dieses Verdrehen der beiden Basis-Klemmenträger 2 dadurch, daß die der Seite mit dem Rasthaken 32 gegenüberliegenden Enden der Basis-Klemmenträger 2 auseinandergezogen werden (die Drehachse liegt senkrecht zur Tragschienenachse; siehe den rechten Bereich der Fig. 2).At this point, the invention starts with the idea of one of the locking hooks 32 to be designed in such a way that it can be operated without an actuating tool from the adjacent terminal can be solved. Of course, this should continue to be ensured be that this locking hook 32 is not accidentally released from the adjacent terminal can be. The invention solves this problem in that the additional latching hook 32 is formed such that the latching hook 32 with the latching recess 40 Adjacent terminal or the neighboring base terminal support 2 cooperates in such a way that the adjacent base terminal support 2 on the mounting rail 3 by twisting apart the terminal blocks are detachable from each other. According to the embodiment this twisting of the two base terminal supports 2 takes place in that the Side with the locking hook 32 opposite ends of the base terminal support 2 be pulled apart (the axis of rotation is perpendicular to the mounting rail axis; see the right area of Fig. 2).

Der Rasthaken 32 erstreckt sich beinahe über die Breite von zwei nebeneinanderliegenden Basis-Klemmenträgern 2. Wie in Fig. 3 zu erkennen, setzt der Rasthaken 32 an einer ersten Außenwandung 53a an, durchquert den Basis-Klemmenträger 2, tritt an der gegenüberliegenden Außenseite 53b aus dem Basis-Klemmenträger 2 aus und ragt in die Öffnung 40 des benachbarten Basis-Klemmenträgers 2 hinein, und zwar noch annähernd über die gesamte Breite des Nachbar-Basis-Klemmenträgers 2 hinweg. Der Rasthaken 32 weist zwei Stege 54, 56 auf, deren Querschnitt im wesentlichen rechteckig ist, wobei die breiteren Seiten der Rechtecke jeweils im wesentlichen rechtwinklig zueinander ausgerichtet sind. Die beiden Stege 54, 56 sind relativ zur Tragschiene 3 winklig ausgerichtet, wobei der Steigungswinkel der beiden Stege 54, 56 relativ zur Tragschiene 3 verschieden groß ist.The locking hook 32 extends almost across the width of two side by side Basic terminal supports 2. As can be seen in FIG. 3, the latching hook 32 attaches a first outer wall 53a, crosses the base terminal support 2, occurs the opposite outside 53b from the base terminal support 2 and protrudes into the opening 40 of the adjacent base terminal support 2, and still approximately over the entire width of the neighboring base terminal support 2. The Locking hook 32 has two webs 54, 56, the cross section of which is essentially rectangular is, the wider sides of the rectangles each being substantially rectangular are aligned with each other. The two webs 54, 56 are relative to the mounting rail 3 angularly aligned, the pitch angle of the two webs 54, 56 relative to Carrier rail 3 is different in size.

Einer der Stege - der relativ zur Tragschiene 3 steiler ansteigende Steg 56 - bildet eine Steuer- und Führungsfläche 58 zur Führung der Bewegung des Rasthakens 32 beim Eintauchen des Rasthakens 32 in die Öffnung 40 des Nachbar-Basis-Klemmenträgers 2. Die Steuerfläche 58 enthält eine kurze, steile Rampe 60 und einen sich (in Einschubrichtung) daran anschließenden, im wesentlichen zur Tragschiene 3 parallelen Abschnitt 62.One of the webs - the web 56, which rises steeply relative to the mounting rail 3 - forms one Control and guide surface 58 for guiding the movement of the locking hook 32 when Immersion of the locking hook 32 in the opening 40 of the neighboring base terminal support 2. The control surface 58 contains a short, steep ramp 60 and one itself (in the direction of insertion) adjoining it, essentially parallel to the mounting rail 3 Section 62.

Die beiden Stege 54, 56 sind in ihrem Endbereich über den Rasthakenkopf 36 miteinander verbunden. Der Rasthakenkopf 36 ist an seiner vom Basis-Klemmenträger 2 abgewandten Außenseite mit einer Einführschräge 66 versehen, um an einer Rastkante 44 des Nachbar-Basis-Klemmenträgers 2 vorbeigleiten zu können. An seiner dem Basis-Klemmenträger 2 zugewandten Seite weist der Rasthakenkopf 36 eine senkrechte Rastkante 68 auf, die dazu bestimmt ist, den eigentlichen Hintergriff zur Rastkante 44 des Nachbarmodules bzw. des Nachbar-Basis-Klemmenträgers 2 zu bilden.The two webs 54, 56 are connected to one another in their end region via the latching hook head 36 connected. The latching hook head 36 is on its from the base terminal support 2 facing away from the outside with an insertion bevel 66 to a locking edge 44 of the neighboring base terminal support 2 can slide past. At its the base terminal support 2 facing side, the locking hook head 36 has a vertical Locking edge 68, which is intended to actually engage behind the locking edge 44 to form the neighboring module or the neighboring base terminal support 2.

Ein Teil der Rastkante 68 ist als Kulisse 70 ausgebildet und bildet eine Entriegelungsfläche, welche geneigt zur Hauptebene bzw. zur Verbindungsfläche benachbarter Basis-Klemmenträger 2 und geneigt zur Tragschiene 3 ausgebildet ist.Part of the locking edge 68 is designed as a backdrop 70 and forms an unlocking surface, which is inclined to the main plane or to the connecting surface of adjacent base terminal supports 2 and is inclined to the mounting rail 3.

An seiner dem Rasthakenkopf 36 jeweils gegenüberliegenden Seite ist der Basis-Klemmenträger 2 mit der bereits erwähnten Öffnung 40 zur Aufnahme des Rast- und Rasthakens 32 versehen. Die untere Wandung der Öffnung 40 wird von den oberen Wandungen der Stege 54, 56 ausgebildet. Die Rastkante 44 ist an einer Wandung 72 im Nachbar-Modul ausgebildet, welche die Ausnehmung 40 des Nachbarmoduls vorzugsweise an der Oberseite begrenzt (denkbar sind natürlich auch um 180° oder 90° axial gedrehte Anordnungen des Rasthakens 32). Die Kontur der Rastkante 44 ist der Kontur der Rastkante 68 nebst der Kulisse 70 angepaßt.The base terminal support is on its side opposite the latching hook head 36 2 with the already mentioned opening 40 for receiving the locking and Detent hook 32 provided. The lower wall of the opening 40 is from the upper Walls of the webs 54, 56 formed. The locking edge 44 is on a wall 72 formed in the neighboring module, which preferably the recess 40 of the neighboring module limited at the top (of course, 180 ° or 90 ° are also conceivable axially rotated arrangements of the locking hook 32). The contour of the locking edge 44 is the Adjusted contour of the locking edge 68 together with the backdrop 70.

Die Funktion des Rasthakens 32 ist wie folgt. The function of the locking hook 32 is as follows.

Die Verriegelung bzw. Zusammenkopplung jeweils benachbarter Basis-Klemmenträger 2 erfolgt durch Zusammenschieben der benachbarten Basis-Klemmenträger 2 auf der Tragschiene 3, wobei der Rast- und Rasthaken 32 des einzuschiebenden Moduls mit seiner Unterseite auf der oberen Steuerfläche 58 des Rasthakens 32 des benachbarten Moduls in die Ausnehmung des Nachbarmoduls gleitet, dabei in die Rastposition angehoben wird und sich beim Hochgleiten axial in sich verdreht, bis der Rastkopf 36 hinter die Rastkante 44 des Nachbarmoduls schnappt/greift.The locking or coupling together of adjacent basic terminal supports 2 is done by pushing together the adjacent basic terminal supports 2 on the mounting rail 3, the latching and latching hook 32 of the insert Module with its underside on the upper control surface 58 of the locking hook 32 of the neighboring module slides into the recess of the neighboring module, thereby is raised to the locking position and rotates axially when sliding up, until the locking head 36 snaps / engages behind the locking edge 44 of the neighboring module.

Die Entriegelung erfolgt über die Aufhebung der Parallelität der benachbarten Module bzw. Basis-Klemmenträger zueinander, wobei die zur Hauptebene geneigte Fläche des Rasthakenkopfes 36 des zu entriegelnden Basis-Klemmenträgers 2 bzw. des Moduls (nachdem der weitere Rasthaken 30 wie bereist beschrieben gelöst wurde) an der oberen Kante/Kulisse der Ausnehmung 40 des Nachbarmoduls entlanggleitet, wodurch der Rastkopf 36 abgesenkt wird und beim weiteren Auseinanderziehen der benachbarten Module schließlich nach Überschreiten einer Grenzbelastung an der Rastkante 44 des Nachbarmodules vorbeigleitet, so daß der Hintergriff gelöst wird.Unlocking is done by removing the parallelism of the neighboring modules or base terminal support to each other, wherein the surface inclined to the main plane of the Locking hook head 36 of the base terminal support 2 to be unlocked or of the module (after the further locking hook 30 has been released as already described) on the upper one Edge / backdrop of the recess 40 of the neighboring module slides, whereby the locking head 36 is lowered and the further pulling apart the neighboring Finally, modules after exceeding a limit load on the locking edge 44 of the neighboring module slides past, so that the rear grip is released.

Die Entriegelung erfolgt somit im wesentlichen lediglich durch ein Auseinanderdrehen der beiden benachbarten Basis-Klemmenträger 2, wobei ein Abgleiten über eine Kulissenkante 71 der bei einem Verdrehen des Rasthakens 32 in seine ursprüngliche Position erfolgt. The unlocking is therefore essentially only by twisting apart of the two adjacent base terminal supports 2, slipping over a guide edge 71 the when the locking hook 32 is rotated into its original position he follows.
