Description

Die Erfindung betrifft eine Verteilerleiste mit mehreren, nebeneinander angeordneten, Stromschienenstücke beinhaltenden Leiteranschlüssen und einer Querverteilung der elektrischen Leistung.The invention relates to a distribution strip with a plurality of conductor connections arranged next to one another and comprising conductor rail pieces and a transverse distribution of the electrical power.

Verteilerleisten der gattungsgemäßen Art werden zur versorgungstechnischen und steuertechnischen Verknüpfung von elektrischen Bauteilen wie beispielsweise Spannungsquellen und Signalempfänger eingesetzt. Sie können für diesen Anwendungszweck beispielsweise zum Aufbau von Initiatorklemmenblöcken verwendet werden, wie dies beispielsweise in der EP 0 222 030 A2 dargelegt ist. In dieser Literaturstelle wird ausgeführt, daß die Versorgungsleitungen einer Spannungsquelle an zwei in einem Initiatorklemmenblock befindlichen Verteilerleisten angeschlossen werden und die Versorgungsspannung von dort über innenliegende Querverbindungsleisten auf mehrere nebeneinander angeordnete Anschlußklemmen verteilt wird, an die wiederum Versorgungsleitungen beispielsweise von Initiatoren für elektrische Signalempfänger angeschlossen werden. Der Aufbau der für diesen Anwendungszweck verwendeten Verteilerleisten ist relativ aufwendig, da zwischen den Stromschienenstücken der Leiteranschlüsse und den Bauteilen für die eigentliche Querverteilung der elektrischen Leistung zusätzliche Bauteile wie beispielsweise Distanzhülsen vorhanden sein müssen, wobei sich bei jedem Stromübergang zwischen den Bauteilen natürlich ein Übergangswiderstand ergibt.Distribution strips of the generic type are used for the supply-related and control-related connection of electrical components such as voltage sources and signal receivers. For this purpose, they can be used, for example, to build up initiator terminal blocks, as set out, for example, in EP 0 222 030 A2. In this reference, it is stated that the supply lines of a voltage source are connected to two distribution strips located in an initiator terminal block and the supply voltage is distributed from there via internal cross-connection strips to a plurality of connecting terminals arranged next to one another, to which supply lines are connected, for example, from initiators for electrical signal receivers. The structure of the distribution strips used for this application is relatively complex since additional components such as spacer sleeves must be present between the conductor rail sections of the conductor connections and the components for the actual transverse distribution of the electrical power, with a transition resistance naturally occurring with each current transfer between the components.

Aufgabe der vorliegenden Erfindung ist es daher, eine Verteilerleiste der gattungsgemäßen Art zu schaffen, bei der die Querverteilung der elektrischen Leistung mit denkbar geringem konstruktiven und montagemäßigen Aufwand erfolgt.The object of the present invention is therefore to create a distribution strip of the generic type in which the transverse distribution of the electrical power takes place with the least possible constructional and assembly-related effort.

Die erfindungsgemäße Lösung besteht darin, daß zur Querverteilung der elektrischen Leistung die Stromschienenstücke der Leiteranschlüsse Steckkontaktelemente zur elektrischen Verbindung der Stromschienenstücke miteinander aufweisen.The solution according to the invention consists in that for the transverse distribution of the electrical power, the conductor rail pieces of the conductor connections have plug contact elements for the electrical connection of the conductor rail pieces to one another.

Aufgrund dieser neuartigen Bauweise entfallen bei den Verteilerleisten der erfindungsgemäßen Art alle bisher vorhandenen zusätzlichen Bauteile wie beispielsweise Querverteilungsschienen, Distanzhülsen oder dergleichen. Dies führt zu einer erheblichen Reduktion des Montageaufwandes und somit der Montagekosten, außerdem entfallen sämtliche Kosten für die Herstellung der entfallenen Bauelemente. Durch die direkte Verbindung der Stromschienenstücke miteinander entfällt je nach Bauweise der üblichen Verteilerleisten mindestens eine Verbindung von zwei stromführenden Bauteilen, d. h. ein Übergangswiderstand zwischen diesen Bauteilen entfällt.Because of this new type of construction, all previously existing additional components, such as, for example, transverse distribution rails, spacer sleeves or the like, are eliminated in the distributor strips of the type according to the invention. This leads to a considerable reduction in the assembly effort and thus the assembly costs, and also eliminates all costs for the production of the components that are omitted. Due to the direct connection of the busbar pieces to one another, depending on the construction of the usual distribution strips, at least one connection of two current-carrying components is eliminated, ie. H. there is no contact resistance between these components.

Die Steckkontaktelemente bilden beim seitlichen Aneinanderreihen der Leiteranschlüsse zu einer Verteilerleiste durch Verrastung eines Steckkontaktes in einem Buchsenkontakt automatisch eine elektrische Verbindung, so daß eine zusätzliche Kontrolle bei der Montage dahingehend, ob alle Querverbindungen der Querverteilung hergestellt worden sind, entfällt. Durch die Steckkontaktierung der Stromschienenstücke der einzelnen Leiteranschlüsse lassen sich diese zu Verteilerleisten beliebiger Länge, d. h. beliebiger Leiteranschlußzahl zusammenfügen. Hierdurch lassen sich Verteilerleisten für jeden Verwendungszweck aufbauen, die wiederum beispielsweise für den Aufbau von Initiatorenklemmenblöcken beliebiger Polzahl Verwendung finden. Der Platzbedarf läßt sich somit erheblich reduzieren, je nachdem, wie häufig derartige Verteilerleisten Anwendung finden.The plug contact elements automatically form an electrical connection when the conductor connections are lined up laterally to form a distribution strip by latching a plug contact in a socket contact, so that there is no additional control during assembly to determine whether all cross connections of the cross distribution have been made. Through the plug-in connection of the busbar pieces of the individual conductor connections, these can be joined together to form distribution strips of any length, ie any number of conductor connections. As a result, distribution strips can be constructed for any purpose, which in turn can be used, for example, for the construction of initiator terminal blocks Find the number of poles. The space requirement can thus be reduced considerably, depending on how often such distribution strips are used.

Spezielle Ausgestaltungen des Gegenstandes der Erfindung ergeben sich aus den Merkmalen der Unteransprüche.Special configurations of the subject matter of the invention result from the features of the subclaims.

Gemäß einer bevorzugten Ausführungsform weisen die Stromschienenstücke einen U-förmigen Grundkörper auf mit je zwei seitlichen sich gegenüberliegenden den Buchsenkontakt bildenden Federkontaktschenkeln, wobei an einem der Schenkel eine Steckerlasche angeordnet ist. Die Steckerlasche eines Steckkontaktelementes greift zur Herstellung der elektrischen Verbindung der Stromschienenstücke untereinander jeweils in den Buchsenkontakt des Steckkontaktelementes eines benachbarten Stromschienenstückes ein. Der mit dem Leiteranschluß zu verbindende Leiter wird z. B. über eine Klemmfeder direkt mit dem Stromschienenstück des entsprechenden Leiteranschlusses verbunden. Stecker und Buchsenkontakt sind somit einstückig ausgeführt, was die Herstellungskosten senkt und die Montage vereinfacht.According to a preferred embodiment, the busbar pieces have a U-shaped base body, each with two lateral spring contact legs which form the socket contact and are arranged on one of the legs, a plug tab. The plug tab of a plug-in contact element engages in each case in the socket contact of the plug-in contact element of an adjacent busbar piece in order to produce the electrical connection of the busbar pieces to one another. The conductor to be connected to the conductor connection is, for. B. directly connected to the conductor rail piece of the corresponding conductor connection via a clamping spring. The plug and socket contact are thus made in one piece, which lowers the manufacturing costs and simplifies assembly.

Die Ausführung eines der Steckkontaktelemente als Buchsenkontakt bietet die Möglichkeit, das Buchsenteil aus mehreren Richtungen z. B. von der Seite oder von unten zu kontaktieren. Da der Buchsenkontakt des ersten Leiteranschlusses einer Verteilerleiste für die Verbindung zum nächsten Stromschienenstück bzw. zum Aufbau der Gesamtstromschiene nicht benötigt wird, bietet sich hier die Möglichkeit, zu einer im Bedarfsfall unter den Leiteranschlüssen angeordneten Leiterplatte eine zusätzliche Anschlußmöglichkeit zu schaffen.The execution of one of the plug contact elements as a socket contact offers the possibility of the socket part from several directions z. B. to contact from the side or from below. Since the socket contact of the first conductor connection of a distribution strip is not required for the connection to the next conductor rail section or for the construction of the overall conductor rail, there is the possibility here of creating an additional connection possibility for a circuit board arranged under the conductor connections if necessary.

Es hat sich außerdem als vorteilhaft erwiesen, die Steckkontaktelemente zur elektrischen Verbindung der Stromschienenstücke, d. h. die Steckerlaschen und Buchsenkontakte räumlich unterhalb der Anschlußebene der Leiteranschlüsse anzuordnen.It has also proven to be advantageous to connect the plug contact elements for the electrical connection of the busbar pieces, i. H. arrange the connector tabs and socket contacts spatially below the connection level of the conductor connections.

Dies führt zu einer besonders raumsparenden Bauweise der Verteilerleiste. Da der Anschlußbereich des Leiteranschlusses von oben sehr gut zugänglich ist, lassen sich außer der bereits erwähnten Anschlußmöglichkkeit über eine Klemmfeder auch alle anderen üblichen Anschlußarten des Leiteranschlusses verwirklichen.This leads to a particularly space-saving design of the distributor strip. Since the connection area of the conductor connection is very easily accessible from above, in addition to the connection possibility already mentioned, all other usual types of connection of the conductor connection can also be realized via a clamping spring.

Da der Buchsenkontakt des einzelnen Stromschienenstückes sowohl von unten als auch von der Seite zugänglich ist, lassen sich zur Stromeinspeisung in die Verteilerleiste am Buchsenkontakt zusätzliche Kontaktflächen anordnen, die sowohl in den Buchsenkontakt eingreifen als auch seitlich an der Außenfläche des Buchsenkontaktes eine elektrische Verbindung herstellen können, ebenso ist ein U-förmiger Gabelkontakt zur elektrischen Verbindungsherstellung am Buchsenkontakt denkbar. Insbesondere der gabelförmige Kontakt bietet den Vorteil, daß eine Stromeinspeisung prinzipiell an beliebiger Stelle der Verteilerleiste von unten erfolgen kann. Insbesondere bei beschränkten Platzverhältnissen läßt sich so eine spezielle Einspeiseklemme einsparen. Die Möglichkeit, den Buchsenkontakt sowohl mittig als auch seitlich zu kontaktieren, macht es sehr einfach, mit Hilfe spezieller Öffnungen im Leiteranschlußgehäuse eine Codierungsmöglichkeit des Leiteranschlusses zu schaffen, je nachdem, ob man die Möglichkeit der Stromeinspeisung in das Stromschienenstück durch den mittigen Buchsenkontakt oder den seitlichen Buchsenkontakt ausschaltet.Since the socket contact of the individual conductor rail piece is accessible both from below and from the side, additional contact surfaces can be arranged on the socket contact for feeding current into the distributor strip, which contact surfaces can both engage in the socket contact and can establish an electrical connection on the outer surface of the socket contact. a U-shaped fork contact for making electrical connections at the socket contact is also conceivable. In particular, the fork-shaped contact has the advantage that, in principle, current can be fed in from anywhere at any point on the distributor strip. This is particularly the case when space is limited save a special feed terminal. The possibility of contacting the socket contact both in the middle and on the side makes it very easy to create a coding option for the conductor connection with the help of special openings in the conductor connection housing, depending on whether the possibility of feeding current into the busbar section through the central socket contact or the side Socket contact switches off.

Es muß hervorgehoben werden, daß die Verwendung einer Verteilerleiste der erfindungsgemäßen Art insbesondere für den Aufbau von Initiatorreihenklemmen, wie sie eingangs kurz beschrieben wurden, von großem Vorteil sind. Die spezielle Ausgestaltung einer Initiatorreihenklemme sieht vor, daß mindestens zwei Verteilerleisten in einem Grundgehäuse einer Initiatorreihenklemme, welches auf einer Tragschiene festlegbar ist, angeordnet sind. Die Verbindung zum Grundgehäuse erfolgt über lösbare Steckbefestigungen, so daß die Verteilerleisten einfach und montagefreundlich im Initiatorklemmenblock umgruppiert werden können. Desweiteren lassen die schon angesprochenen Möglichkeiten einer vorteilhaften einfachen Codierung der erfindungsgemäßen Verteilerleiste insbesondere die oftmals notwendige Erdung von Stromschienenanschlüssen sehr einfach realisierbar erscheinen. Durch die Zugänglichkeit der Stromschienenstücke von unten ist ein Anschluß der Verteilerleiste an die das Erdpotential tragende Tragschiene ohne Probleme realisierbar.It must be emphasized that the use of a distributor strip of the type according to the invention is of great advantage in particular for the construction of initiator terminal blocks, as briefly described at the beginning. The special design of an initiator terminal block provides that at least two distributor strips are arranged in a basic housing of an initiator terminal block, which can be fixed on a mounting rail. The connection to the basic housing is made using detachable plug fasteners, so that the distributor strips can be regrouped in the initiator terminal block in a simple and easy-to-assemble manner. Furthermore, the already mentioned possibilities of an advantageous simple coding of the distributor strip according to the invention, in particular, make the often necessary grounding of busbar connections seem very simple to implement. Due to the accessibility of the busbar sections from below, a connection of the distribution strip to the mounting rail carrying the earth potential can be implemented without problems.

Es bleibt noch anzumerken, daß die lösbare Verbindung der Verteilerleisten innerhalb des Initiatorklemmenblockgrundgehäuses eine Kontaktierung zur Beschaltung über Steckkontakte, d. h. die Realisierung von PNP- bzw. NPN-Schaltungen durch einfaches Umstecken der Verteilerleisten sehr einfach macht.It remains to be noted that the detachable connection of the distribution strips within the initiator terminal block base housing is a contact for connection via plug contacts, i. H. makes the implementation of PNP or NPN circuits very easy by simply repositioning the distribution strips.

Im folgenden werden einige Beispiele von Verteilerleisten der erfindungsgemäßen Art sowie die Verwendung von Verteilerleisten in Initiatorklemmenblöcken anhand der beigefügten Zeichnungen zum besseren Verständnis näher erläutert werden.The following are some examples of distribution strips of the type according to the invention as well as the use of distribution strips in initiator terminal blocks will be explained in more detail with reference to the accompanying drawings for better understanding.

The structure of a conductor connection 2 is illustrated with the aid of the sectional diagram in FIG. 2. In the middle of the conductor connection housing 10, the conductor rail section 4 can again be seen there. On this busbar piece 4, a clamping spring 14 is arranged, which serves to press the conductor 3 from above into the insertion funnel 13 of the conductor connection housing 10, to press under the busbar piece 4 and to fix it there by clamping spring force. On the top of the conductor connection housing 10 there is a mounting opening 15 on the side next to the insertion funnel 13, through which an actuation of the clamping spring 14 for the mounting process of the conductor 3 is possible. Each wire junction box has on one side wall connecting cams 12, which correspond in position and size with corresponding connecting bores 11 on the opposite side surface of the conductor connection housing 10, so that when a row of conductor connections 2 is lined up, these engage one another by the engagement of the connecting cams 12 in the corresponding connecting bores 11 of the adjacent conductor connection 2 are set.

Bei der Aneinanderreihung von Leiteranschlüssen 2 greifen die in jedem Leiteranschluß 2 befindlichen Stromschienenstücke 4 mittels ihrer Steckkontaktelemente 5 ineinander, so daß eine elektrisch leitende Verbindung zwischen den einzelnen Leiteranschlüssen 2 hergestellt ist. Um dies zu verdeutlichen, sind in Figur 3 drei Stromschienenstücke 4 dargestellt, wobei zum besseren Verständnis die entsprechenden Leiteranschlußgehäuse 10 weggelassen wurden. Jedes Stromschienenstück 4 besitzt einen U-förmigen Grundkörper 21, der aus zwei Federkontaktschenkeln 23 und 24 sowie einem sie verbindenden Schenkelverbindungsblech 25 besteht.When stringing together conductor connections 2, the busbar pieces 4 located in each conductor connection 2 engage with one another by means of their plug contact elements 5, so that an electrically conductive connection between the individual conductor connections 2 is established. In order to clarify this, three busbar pieces 4 are shown in FIG. 3, the corresponding conductor connection housings 10 being omitted for better understanding. Each busbar piece 4 has a U-shaped base body 21, which consists of two spring contact legs 23 and 24 and a leg connecting plate 25 connecting them.

Die am Federkontaktschenkel 24 seitlich vorstehende und in einem Winkel von ca. 45° abgewinkelte Haltelasche 22 dient dazu, das Stromschienenstück 4 in seiner Position im Leiteranschlußgehäuse 10 zu halten. Zu der der Haltelasche 22 gegenüberliegenden Seite sind sowohl der Federkontaktschenkel 23 als auch der Schenkel 24 seitlich verlängert. Der Federkontaktschenkel 24 besitzt an seinen verlängerten freien Ende eine Steckerlasche 27. Der Federkontaktschenkel 23 ist in Richtung auf den gegenüberliegenden Federkontaktschenkel 24 so gekröpft, daß sich an den gegenüberliegenden freien Enden der beiden Schenkel zwei sich parallel gegenüberliegende, mit Kontaktplättchen 28 und 29 versehene Flächen ergeben, deren Abstand geringer ist als der der Federkontaktschenkel 23 und 24 im Bereich des Grundkörpers 21. Die mit den Kontaktplättchen 28 und 29 versehenen gegenüberliegenden Flächen bilden gemeinsam einen Buchsenkontakt 26. In Figur 3 ist außerdem gut zu erkennen, daß für die Herstellung einer durchgehenden Stromschiene die U-förmigen Grundkörper 21 der Stromschienenstücke 4 so aneinandergereiht werden, daß die Steckerlasche 27 eines Stromschienenstückes in den Buchsenkontakt 26 eines benachbarten Stromschienenstückes eingreifen kann. Hierzu ist es erforderlich, daß die Steckerlasche 27 an ihrem dem Federkontaktschenkel 24 abgewandten Ende so abgekröpft wird, daß ihre Mittelebene mit der sich zwischen den Federkontaktschenkeln 23 und 24 des Buchsenkontaktes 26 ergebenden Mittelebene übereinstimmt.The holding tab 22 protruding laterally on the spring contact leg 24 and angled at an angle of approximately 45 ° serves to hold the busbar piece 4 in its position in the conductor connection housing 10. Both the spring contact leg 23 and the leg 24 are laterally extended to the side opposite the retaining tab 22. The spring contact leg 24 has a plug tab 27 at its extended free end. The spring contact leg 23 is cranked in the direction of the opposite spring contact leg 24 in such a way that at the opposite free ends of the two legs there are two mutually opposite surfaces provided with contact plates 28 and 29 , whose distance is less than that of the spring contact legs 23 and 24 in the area of Base body 21. The opposite surfaces provided with the contact plates 28 and 29 together form a socket contact 26. In Figure 3 it can also be clearly seen that for the production of a continuous busbar the U-shaped base body 21 of the busbar pieces 4 are lined up so that the Plug tab 27 of a track piece can engage in the socket contact 26 of an adjacent track piece. For this purpose, it is necessary that the connector tab 27 is bent at its end facing away from the spring contact leg 24 in such a way that its center plane coincides with the center plane resulting between the spring contact legs 23 and 24 of the socket contact 26.

Zusätzlich zu den Stromschienenstücken 4 ist in Figur 3 an einem Stromschienenstück 4 die Klemmfeder 14 dargestellt, die auf die Außenseite des Federkontaktschenkels 24 aufgesetzt ist. Sie besitzt an ihrer der Haltelasche 22 zugewandten Seite einen Durchbruch 30 und ist so geformt, daß sie eine Federkraft in Richtung des Pfeiles F erzeugt. Da die Haltelasche 22 durch den Durchbruch 30 ragt, ist die Bewebung des freien Schenkels 32 der Klemmfeder 14 in Richtung des Pfeiles F beschränkt. Wird eine Gegenkraft auf die Kante 31 der Klemmfeder 14 ausgebübt, so bewegt sich ihr freier Schenkel 32 mit dem Durchbruch 30 entgegen des Pfeiles F nach unten, so daß in den Innenraum des U-förmigen Grundkörpers 21 des Stromschienen. stückes 4 ein Anschlußdraht eingeschoben werden kann. Nach Loslassen der Klemmfeder 14 schnellt der freie Schenkel 32 infolge der Federkraft in Richtung des Pfeiles F nach oben, drückt den Anschlußdraht unter den Federkontaktschenkel 24 des Stromschienenstückes 4 und fixiert ihn dort. Diese Art der KLemmbefestigung erfordert einen sehr geringen Montageaufwand, da sich die Verbindung eines Anschlußdrahtes am Stromschienenstück 4 schnell und ohne besondere Montagemittel bewerkstelligen läßt. Natürlich sind außer einer Klemmbefestigung alle denkbaren anderen Arten der Herstellung einer Verbindung von Leiter und Stromschienenstück Schraub-, Flachstecker, Lötanschluß und dergleichen.In addition to the conductor rail pieces 4, the clamping spring 14 is shown on a conductor rail piece 4 in FIG. 3, which is placed on the outside of the spring contact leg 24. It has an opening 30 on its side facing the retaining tab 22 and is shaped in such a way that it generates a spring force in the direction of the arrow F. Since the retaining tab 22 protrudes through the opening 30, the movement of the free leg 32 of the clamping spring 14 in the direction of the arrow F is limited. If a counterforce is exerted on the edge 31 of the clamping spring 14, its free leg 32 moves downward with the opening 30 counter to the arrow F, so that the busbars enter the interior of the U-shaped base body 21. piece 4 a connecting wire can be inserted. After releasing the clamping spring 14, the free leg 32 snaps upward as a result of the spring force in the direction of arrow F, presses the connecting wire under the spring contact leg 24 of the conductor rail piece 4 and fixes it there. This type of clamp attachment requires very little assembly effort, since the connection of a connecting wire to the conductor rail section 4 can be accomplished quickly and without special assembly means. Of course, apart from a clamp, all conceivable other types of making a connection between the conductor and the conductor rail piece are screw, flat plug, solder connection and the like.

Die Darstellung der aneinandergereihten Stromschienenstücke 4 in Figur 3 macht deutlich, daß der jeweils erste Buchsenkontakt 26 einer Verteilerleiste für die Stromübertragung innerhalb der Stromschiene nicht benötigt wird. Aus diesem Grunde kann dieser Buchsenkontakt ebenso wie die Verbindung des Stromschienenstückes 4 mit einem Leiter 3 dazu benutzt werden, eine weitere elektrische Verbindung zur Stromschiene herzustellen. In Figur 1 und 2 ist eine Möglichkeit der Kontaktierung der Stromschiene von der Unterseite des Leiteranschlusses 2 her über den Buchsenkontakt 26 dargestellt. Das Ausführungsbeispiel zeigt hierzu einen Lötkontakt 42, der mit einer Leiterplatte 41 elektrisch verbunden ist und an seinem der Leiterplatte 41 abgewandten Ende eine Kontaktplatte 43 besitzt, welche durch eine Öffnung 44 an der Unterseite des Leiteranschlußgehäuses 10 in den Buchsenkontakt 26 des Stromschienenstückes 4 eingreift. Alternativ zu einer Kontaktierung der Stromschiene gemäß den Figuren 1 und 2 zeigt Figur 4 eine Möglichkeit, den Buchsenkontakt 26 an den Außenseiten durch einen Gabelkontakt 40 zu umgreifen. Der Gabelkontakt 40 ist wie der oben beschriebene Lötkontakt 42 elektrisch mit einer Leiterplatte 41 verbunden und umgreift von unten den Buchsenkontakt 26, wobei das Leiteranschlußgehäuse 10 in diesem Falle einen ausreichend dimensionierten Ausbruch 45 an seiner Unterseite aufweist. Für die Kontaktierung der Stromschiene durch den Gabelkontakt 40 ist es im Gegensatz zu dem vorher besprochenen Beispiel nicht notwendig, daß der Buchsenkontakt 26 eines Leiteranschlusses 2 unbenutzt ist, vielmehr kann der Gabelkontakt 40 an jedem beliebigen Leiteranschluß 2 eine Verteilerleiste 1 angreifen, sofern im Leiteranschlußgehäuse 10 der entsprechende Ausbruch 45 zur Aufnahme der seitlich den Buchsenkontakt 26 umgreifenden Gabelteile des Kontaktes 40 vorhanden ist. Eine Verteilerleiste der erfindungsgemäßen Art läßt sich somit über einem in einer Leiterplatte 41 angeordneten Gabelkontakt 40 beliebig positionieren. Außerdem kann bei beengten Platzverhältnissen durch die Einspeisung der Stromschiene von unten ein sonst notwendiger Einspeiseanschluß entfallen, was insbesondere bei beschränkten Platzverhältnissen von Vorteil ist.3 shows that the first socket contact 26 of a distributor strip is not required for the current transmission within the busbar. For this reason, this socket contact, like the connection of the conductor rail piece 4 to a conductor 3, can be used to establish a further electrical connection to the conductor rail. 1 and 2 show a possibility of contacting the busbar from the underside of the conductor connection 2 via the socket contact 26. The exemplary embodiment shows a solder contact 42, which is electrically connected to a circuit board 41 and has at its end facing away from the circuit board 41 a contact plate 43 which engages through an opening 44 on the underside of the conductor connection housing 10 in the socket contact 26 of the busbar piece 4. As an alternative to contacting the busbar according to FIGS. 1 and 2, FIG. 4 shows a possibility of gripping the socket contact 26 on the outside by a fork contact 40. Like the solder contact 42 described above, the fork contact 40 is electrically connected to a printed circuit board 41 and engages around the socket contact 26 from below, in which case the conductor connection housing 10 has a sufficiently dimensioned cutout 45 on its underside. In contrast to the example discussed above, it is not necessary for the contact of the busbar by the fork contact 40 that the socket contact 26 of a conductor connection 2 is not used, rather the fork contact 40 can attack a distribution strip 1 at any conductor connection 2, provided that it is in the conductor connection housing 10 the corresponding cutout 45 for receiving the fork parts of the contact 40 which laterally encompass the socket contact 26 is present. A distributor strip of the type according to the invention can thus be positioned as desired over a fork contact 40 arranged in a printed circuit board 41. In addition, if the space is limited, the power rail can be fed in from below, which is otherwise necessary omitted, which is particularly advantageous when space is limited.

Eine Anwendung von erfindungsgemäßen Verteilerleisten bietet sich insbesondere für den Aufbau von Initiatorklemmenblöcken an. Initiatorklemmenblöcke werden üblicherweise aus einzelnen Initiatorreihenklemmen aufgebaut, in Figur 5 ist beispielhaft eine Initiatorreihenklemme im Querschnitt mit drei zu erfindungsgemäßen Verteilerleisten gehörenden Leiteranschlüssen 2 abgebildet. Ein Initiatorklemmenblock setzt sich aus senkrecht zur Zeichenebene nebeneinander angeordneten Initiatorreihenklemmen 50 zusammen, die senkrecht zur dargestellten Zeichnungsebene miteinander auf einer gemeinsamen genormten Tragschiene 54 festgelegt sind. Durch die Aneinanderreihung der Initiatorenreihenklemmen 50 ergibt sich zwangsläufig ebenso eine Aneinanderreihung der einzelnen Leiteranschlüsse 2 zu Verteilerleisten, die in Figur 5 mit I, II und III bezeichnet sind. Die Initiatorreihenklemme 50 besitzt ein Klemmengehäuse 51 aus Isolierwerkstoff, welches mit Aufnahmestegen 80 zur lösbaren Festlegung der Leiteranschlußgehäuse 10 im Klemmengehäuse 51 versehen ist. Diese Aufnahmestege 80 besitzen kleine Wulste 81, die in korrespondierende Ausnehmungen 82 der Leiteranschlußgehäuse eingreifen. Durch diese Bauweise ist gewährleistet, daß die Leiteranschlüsse 2 innerhalb einer Reihenklemme vertauscht werden können, um z. B. eine PNP-Anordnung in eine NPN-Anordnung zu verwandeln.An application of distribution strips according to the invention is particularly suitable for the construction of initiator terminal blocks. Initiator terminal blocks are usually made up of individual initiator terminal blocks; FIG. 5 shows an example of an initiator terminal block in cross section with three conductor connections 2 belonging to distribution strips according to the invention. An initiator terminal block is composed of initiator terminal blocks 50 which are arranged next to one another perpendicular to the plane of the drawing and which are fixed to one another perpendicularly to the plane of the drawing shown on a common standardized mounting rail 54. The stringing together of the initiator terminal blocks 50 inevitably also results in a stringing together of the individual conductor connections 2 to form distribution strips, which are denoted by I, II and III in FIG. 5. The initiator terminal block 50 has a terminal housing 51 made of insulating material, which is provided with mounting webs 80 for releasably fixing the conductor connection housing 10 in the terminal housing 51. These receiving webs 80 have small beads 81 which engage in corresponding recesses 82 in the conductor connection housing. This design ensures that the conductor connections 2 can be interchanged within a terminal block to z. B. convert a PNP arrangement into an NPN arrangement.

Die Stromschienen der einzelnen Verteilerleisten I, II und III bieten bei Verwendung in Initiatorreihenklemmen selbstverständlich auch die Möglichkeit der Kontaktierung von der Unterseite des Leiteranschlußgehäuses 10. In Figur 5 ist mit Hilfe einer solchen Kontaktierung eine Verbindung der Stromschiene der Verteilerleiste 3 mit der Tragschiene 54 zum Aufbau einer PE-Verteilerleiste dargestellt. Die Verbindung erfolgt durch den Kontaktbügel 58, der durch den Einführtrichter 53 des Leitergehäuses 10 in einen Buchsenkontakt der Stromschiene der Verteilerleiste 3 eingreift. Da der Kontaktbügel 58 in den Buchsenkontakt eindringt, muß die Kontaktierung zwangsläufig am Beginn der Verteilerleiste erfolgen, da hier ein freier Buchsenkontakt vorhanden ist. Der Kontaktbügel 58 ist an ein Übertragungsblech 59 angenietet, das im Initiatorklemmengehäuse 51 festgelegt ist und die Tragschiene 54 berührt, so daß die entsprechende elektrische Verbindung hergestellt ist. Die Festlegung des Initiatorklemmengehäuses 51 an der Tragschiene 54 erfolgt üblicherweise durch zwei Gehäusefüße 56 und 57, die die abgewinkelten Halteschenkel 61 der Tragschiene 54 umgreifen.The busbars of the individual distribution strips I, II and III naturally also offer the possibility of contacting from the underside of the conductor connection housing 10 when used in initiator terminal blocks. In FIG. 5, such a contacting is used to connect the busbar of the distribution strip 3 to the mounting rail 54 for assembly shown a PE distribution strip. The connection is made through the contact bracket 58, which is through the insertion funnel 53 of the conductor housing 10 engages in a socket contact of the busbar of the distributor 3. Since the contact bracket 58 penetrates into the socket contact, the contact must necessarily be made at the beginning of the distribution strip, since there is a free socket contact here. The contact bracket 58 is riveted to a transmission plate 59, which is fixed in the initiator terminal housing 51 and touches the mounting rail 54, so that the corresponding electrical connection is established. The initiator terminal housing 51 is usually fixed on the mounting rail 54 by means of two housing feet 56 and 57 which grip around the angled holding limbs 61 of the mounting rail 54.

In Figur 6 ist eine Initiatorreihenklemme dargestellt, bei der der Schaltzustand des Initiators über eine Kontroll-LED 70 angezeigt wird. In diesem Ausführungsbeispiel greift in einen Leiteranschluß der Verteilerleiste von unten eine Kontaktplatte 72 ein. Die Kontaktplatte 72 ist Bestandteil eines Kontaktwinkels 71, der über eine Drahtbrücke 73 und einen Widerstand 74 mit der Kontroll-LED 70 verbunden ist. Bei der Figur 6 ist besonders zu beachten, daß die Kontaktplatte 72 nicht wie der in Figur 5 beschriebene Kontaktbügel 58 mittig in einen Buchsenkontakt der Stromschiene der Verteilerleiste eingreift, sondern einen der Federkontaktschenkel des Buchsenkontaktes 26 seitlich berührt. Hierbei ist die Kontaktplatte 72 über den Einführtrichter 76 so zwangsgeführt, daß eine andere als die seitliche Kontaktierung des Buchsenkontaktes nicht möglich ist. Hieraus ergibt sich die Tatsache, daß beispielsweise ein Austausch der Verteilerleiste III aus Figur 5 mit der Verteilerleiste II aus Figur 6 nicht möglich ist, da die Einfuhrtrichter 76 und 53 zur Zwangsführung der Kontakte zur Stromschiene der Verteilerleiste nicht übereinstimmen. Durch die Wahl des Kontaktortes an dem Buchsenkontakt einer Stromschiene ergibt sich folglich eine einfache Kodierungsmöglichkeit, falls eine Austauschbarkeit unterschiedlicher Verteilerleisten ausgeschlossen werden soll.An initiator terminal block is shown in FIG. 6, in which the switching state of the initiator is indicated by a control LED 70. In this exemplary embodiment, a contact plate 72 engages in a conductor connection of the distributor strip from below. The contact plate 72 is part of a contact angle 71, which is connected to the control LED 70 via a wire bridge 73 and a resistor 74. In FIG. 6, it is particularly important to note that the contact plate 72 does not engage in the middle of a socket contact on the busbar of the distributor strip, as in the case of the contact bracket 58 described in FIG. 5, but touches one of the spring contact legs of the socket contact 26 laterally. Here, the contact plate 72 is positively guided via the insertion funnel 76 such that contact other than the lateral contact of the socket contact is not possible. This results in the fact that, for example, an exchange of the distributor strip III from FIG. 5 with the distributor strip II from FIG. 6 is not possible, since the insertion funnels 76 and 53 for positive guidance of the contacts to the busbar of the distributor strip do not match. The choice of the contact location on the socket contact of a busbar consequently results in a simple coding option if interchangeability of different distribution strips is to be excluded.
