Abstract

The series clamp (1) has outer contacts (7) to rest on a standard section guide having a base carrier. The base carrier has three parallel conductors, isolated from each other and having conductive contactable surfaces. The base carrier has an earth potential line (11) with screening (12) and a signal line (9). The series clamp has a fixed component (4) to contact the ground potential line (11) and the screening. A moveable component (5) is provided to contact the signal line. The moveable component (5) is formed so that it contacts a first signal line resting on the standard section guide. A movable component of a second series clamp, when supported on the standard section guide, contacts a second signal line directly next to the first clamp (1). A short circuit bridge (8) connects the components (4,5) with outer contacts (7,8) and has a power amplifier, relay or thyristor.

Die vorliegende Erfindung betrifft eine Reihenklemme zum Aufrasten auf eine Normprofilschiene, die die Übertragung von Signalen zwischen Ein- und/oder Ausgängen einer speicherprogrammierbaren Steuerung (SPS) und Ein-/Ausgabebaugruppen gewährleistet.The present invention relates to a terminal block for snapping on a standard mounting rail that supports the transfer of Signals between inputs and / or outputs of a programmable logic controller Control (PLC) and input / output modules guaranteed.

Solche Reihenklemmen werden bisher mit jedem einzelnen Einbau- bzw. Ausgangskanal der SPS verdrahtet. Nachteilig an dieser Verdrahtung sind der hohe Aufwand und die hohen Kosten, da mindestens vier Klemmstellen pro Kanal zwischen SPS und Reihenklemme notwendig sind. Diese Klemmstellen sind überdies potentielle Fehlerquellen.Such terminal blocks have so far been wired to each individual installation or output channel of the PLC. Disadvantageous this wiring is the high effort and the high costs, since at least four clamping points per channel between the PLC and terminal block are necessary. These nips are moreover potential sources of error.

Die Aufgabe wird erfindungsgemäß mit einer Reihenklemme der obengenannten Art dadurch gelöst, daß ein in die Normprofilschiene einlegbarer Grundträger vorgesehen ist, der mindestens drei parallel zueinander verlaufende Leiterbahnen aufweist, die gegeneinander isoliert sind, deren Oberfläche jedoch elektrisch leitend kontaktierbar ist, wobei als Leiterbahnen eine Massepotential führende Massepotentialleiterbahn, eine Schirmleiterbahn zur Schirmableitung und mindestens eine Signalleiterbahn zur Signalweiterleitung vorgesehen sind und wobei die Reihenklemme jeweils einen ortsfesten Abnehmer zur Kontaktierung der Massepotentialleiterbahn und der Schirmleiterbahn sowie einen beweglichen Abnehmer zur Kontaktierung einer Signalleiterbahn aufweist. The object is achieved with a terminal block Solved above type in that a in the standard rail insertable base support is provided, the at least has three conductor tracks running parallel to one another, which are isolated from each other, but their surface can be electrically conductively contacted, with conductor tracks a ground potential conductor track carrying ground potential, a shield conductor for shield derivation and at least one Signal conductor track are provided for signal transmission and the terminal block each having a fixed customer Contacting the ground potential conductor track and the shield conductor track as well as a movable customer for contacting has a signal conductor track.

Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Reihenklemme 1 ist in Fig. 1 dargestellt. Zum Aufrasten auf eine Normschiene 16 weist sie eine Ausnehmung 2 mit zwei Vorsprüngen 3 auf, die beim Aufrasten in entsprechende Ausnehmungen der Normschiene 16 greifen. In der Ausnehmung 2 sind außerdem jeweils ein ortsfester Abnehmer 4 zur Kontaktierung der Massepotentialleiterbahn und der Schirmleiterbahn und ein beweglicher Abnehmer 5 zur Kontaktierung einer Signalleiterbahn vorgesehen. Diese Abnehmer 4, 5 sind über Signalleitungen 6 mit Außenkontakten 7 verbunden. Diese Verbindung wird über eine Kurzschlußbrücke 8 hergestellt, die in eine dafür vorgesehene Ausnehmung einschiebbar ist.An advantageous embodiment of the terminal block according to the invention 1 is shown in FIG. 1. To snap onto one Standard rail 16 has a recess 2 with two projections 3, which when snapped into corresponding recesses the standard rail 16 grab. In the recess 2 are also in each case a stationary customer 4 for contacting the ground potential conductor track and the shield conductor track and a movable one Pickup 5 for contacting a signal conductor intended. These customers 4, 5 are via signal lines 6 connected to external contacts 7. This connection is about a short-circuit bridge 8 is produced, which in a designated Recess can be inserted.

Aus Fig. 2 ist die Form des beweglichen Abnehmers 5 ersichtlich. Er weist zwei Vorsprünge auf, die rechts und links über die Reihenklemme 1 herausragen. Diese Vorsprünge sind um den Abstand a in der Höhe gegeneinander versetzt. Dieser Abstand a entspricht dem Abstand zwischen zwei Signalleiterbahnen des Grundträgers. Durch diese Ausformung des beweglichen Abnehmers 5 wird erreicht, daß der bewegliche Abnehmer einer zweiten Reihenklemme bei ihrer Montage rechts neben der dargestellten Reihenklemmme 1 durch den Kontakt der jeweiligen Vorsprünge so positioniert wird, daß er eine Signalleiterbahn kontaktiert, die sich unmittelbar unterhalb der von der dargestellten Reihenklemme 1 kontaktierten Signalleiterbahn befindet.2 shows the shape of the movable pickup 5. It has two protrusions, the right and left over protrude from terminal block 1. These ledges are around Distance a offset in height. This distance a corresponds to the distance between two signal tracks of the Basic carrier. This shape of the movable customer 5 is achieved that the movable customer of a second Terminal block when installed to the right of the one shown Terminal block 1 through the contact of the respective Projections is positioned so that it is a signal trace contacted, which is immediately below that shown by the Terminal 1 contacted signal conductor.

Auf diese Weise kontaktiert der bewegliche Abnehmer 5 einer Reihenklemme jeweils die Signalleiterbahn unterhalb der Signalleiterbahn, die von der jeweils vorangehenden Reihenklemme 1 kontaktiert wird. Eine Anordnung aus acht Reihenklemmen 1, die gemäß des Ausführungsbeispiels die acht Signalleiterbahnen 9 eines Grundträgers 10 in einer Normschiene 16 kontaktieren, ist in Fig. 3 dargestellt. Abgesehen von den acht Signalleiterbahnen 9 weist der Grundträger 10 noch eine Massepotentialleiterbahn 11 und eine Schirmleiterbahn 12 auf. Signale von einer (nicht dargestellten) SPS gelangen mittels eines Kopfmoduls 13, das über einen Pfostenstecker 14 mit dem Grundträger 10 verbunden ist, in die Signalleiterbahnen 9.In this way, the movable customer 5 contacts one Terminal block each the signal conductor below the signal conductor, from the previous terminal block 1 is contacted. An arrangement of eight terminal blocks 1, according to the exemplary embodiment, the eight signal conductor tracks 9 of a base support 10 in a standard rail 16 contact is shown in Fig. 3. Except the The basic carrier 10 has eight signal conductor tracks 9 Ground potential conductor track 11 and a shield conductor track 12. Signals from a (not shown) PLC get through a head module 13 which is connected to the Base carrier 10 is connected into the signal conductor tracks 9.

Die Verbindung dieser Kopfmodule 13 mit der (nicht dargestellten) speicherprogrammierbaren Steuerung erfolgt über die aus Fig. 4 ersichtlichen Flachbandkabel 15. Sie verbinden jedes Kopfmodul 13 mit einem Kabelkanal 17. Jedes Flachbandkabel 15 überträgt im Ausführungsbeispiel acht Bits parallel, entsprechend den acht Signalleiterbahnen 9 im Grundträger 10. Durch Verwendung mehrerer Gruppen von acht Reihenklemmen 1 und jeweils einem Kopfmodul 13 können beispielsweise auch Anordnungen zur Kontaktierung von 32, 64 oder 128 Ein- und/oder Ausgängen einer speicherprogrammierbaren Steuerung zusammengesetzt werden.The connection of these head modules 13 to the (not shown) programmable logic control is carried out via the 4 apparent ribbon cable 15. They connect each Head module 13 with a cable duct 17. Each ribbon cable 15 transmits eight bits in parallel in the exemplary embodiment, corresponding to the eight signal conductor tracks 9 in the base carrier 10. By using several groups of eight terminal blocks 1 and a head module 13, for example, can also be arrangements for contacting 32, 64 or 128 inputs and / or Outputs of a programmable logic controller become.
