Description

Die Erfindung betrifft einen Kontakteinsatz für Industriestecker gemäß dem Oberbegriff des Patentanspruchs 1The invention relates to a contact insert for industrial plugs according to the preamble of patent claim 1

Industriestecker werden überall dort eingesetzt, wo eine rauhe Industrieumgebung zuverlässige Verbindungen von Kraft- und Steuerstromleitungen erfordern. Derartige Industriestecker bestehen aus einem robusten Gehäuse und aus einem in das Gehäuse einsetzbaren Kontakteinsatz. Es gibt eine Vielzahl, meist genormter Gehäusetypen, die sich in Form und Größe unterscheiden und unterschiedliche Kontakteinsätze der verschiedensten Leistungsklassen mit bis zu 216 Polen aufnehmen können. Der Anschluß eines elektrischen Leiters an den Kontakteinsatz erfolgt dabei mit Hilfe von Schraub-, Federkraft- oder Crimpanschlüssen.Industrial plugs are used wherever a harsh industrial environment requires reliable connections of power and control power lines. Such industrial plugs consist of a robust housing and of a contact insert which can be inserted into the housing. There are a variety, mostly standardized housing types, which differ in shape and size and can accommodate different contact inserts of different performance classes with up to 216 poles. The connection of an electrical conductor to the contact insert takes place with the aid of screw, spring force or crimp connections.

Vorverdrahtete Industriestecker der zuvor beschriebenen Art können einfach auf - beispielsweise innerhalb eines Schaltschrankes angeordnete - Klemmadapter aufgerastet und mittels eines oder mehrerer Verriegelungsbügel befestigt werden. Mit derartigen marktüblichen Industriesteckern ist es zwar möglich, alle Pole des Industriesteckers mit einem Handgriff sicher in Kontakt zu bringen, ohne den Schaltschrank vorher öffnen zu müssen, jedoch ist die Vorverdrahtung im Verhältnis dazu relativ umständlich, da jede Ader einzeln abisoliert werden muß, bevor sie mit dem entsprechenden Anschluß kontaktiert werden kann.Prewired industrial plugs of the type described above can be easily snapped onto - for example, within a control cabinet arranged - clamp adapter and secured by means of one or more locking bracket. With such commercially available industrial connectors while it is possible to bring all the poles of the industrial connector with a handle safely in contact without having to open the cabinet before, but the pre-wiring is relatively cumbersome in relation to this, since each wire must be individually stripped before they can be contacted with the appropriate connection.

Die US 5,620,332 A offenbart ein Anschlußelement mit elektrischen Kontakten in Schneid-Anschlußtechnik zum abisolierfreien Anschluß von elektrischen Leitern. In den Kammern des Anschlußelements sind jeweils ein Betätigungsschieber und ein Schneidelement angeordnet, wobei die Schiebeteile jeweils relativ zu den Schneidelementen verschiebbar angeordnet sind Das bekannte Anschlußelement dient dabei zur elektrischen Verbindung von zwei Leitern, die in an gegenüberliegenden Seiten des Gehäuses angeordneten Öffnungen eingeschobenen werden; als Kontakteinsatz für einen Industriestecker ist das Anschlußelement dagegen nicht vorgesehen.The US 5,620,332 A discloses a connection element with electrical contacts in cutting-connection technology for the stripping-free connection of electrical conductors. In the chambers of the connecting element, an actuating slide and a cutting element are arranged in each case, wherein the sliding parts are each arranged displaceably relative to the cutting elements The known connecting element serves for the electrical connection of two conductors which are inserted in openings arranged on opposite sides of the housing; as a contact insert for an industrial plug, however, the connection element is not provided.

Die US 4,466,682 A offenbart eine Reihenklemine mit einen Kontakteinsatz mit Anschlüssen in Schneidanschlußtechnik, mit dessen Hilfe zwei Leiter abisolationsfrei miteinander verbunden werden können.The US 4,466,682 A discloses a series terminals with a contact insert with connections in cutting connection technology, with the help of two conductors can be connected to each other without insulation.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Verwendungsmöglichkeiten des Kontakteinsatzes zu erweitern. Diese Aufgabe ist bei dem zuvor beschriebenen Kontakteinsatz mit den Merkmalen des Patentanspruchs 1 dadurch gelöst, daß mindestens zwei Stiftkontakte oder mindestens zwei Buchsenkontakte vorgesehen sind, daß die Schneidelemente den elektrischen Kontakt der in dem Kontakteinsatz eingesteckten Leiter über jeweils eine Stromschiene mit einem Stiftkontakt oder einen Buchsenkontakt herstellen, so daß jeder Stiftkontakt bzw. jeder Buchsenkontakt mit einem Anschluß elektrisch verbunden ist, daß der Betätigungsschieber eine Aufnahme zum Eingriff eines Hilfsmittels aufweist und mit dem Hilfsmittel der Betätigungsschieber von einem Zustand, in dem das Einstecken eines ankommenden Leiters möglich ist, in den kontaktierten Zustand geführt werden kann, und daß eine zur Führung des Hilfsmittels geeignete Betätigungshilfe vorgesehen ist, die gleichzeitig als Widerlager für das Hilfsmittel dient..The present invention has for its object to expand the uses of the contact insert. This object is achieved in the contact insert described above with the features of claim 1, characterized in that at least two pin contacts or at least two socket contacts are provided, that the cutting elements the electrical contact of the inserted in the contact insert conductor via a respective busbar with a pin contact or a socket contact make, so that each pin contact or each socket contact is electrically connected to a terminal, that the actuating slide has a receptacle for engaging an aid and with the aid of the actuating slide from a state in which the insertion of an incoming conductor is possible in the contacted Condition can be performed, and that a suitable for guiding the aid actuating aid is provided, which also serves as an abutment for the aid.

Der Kontakteinsatz ist zum Anschluß isolierter Leiter geeignet, da die Anschlüsse als Schneidanschlüsse ausgebildet sind. Durch die Verwendung der bereits bei Reihenklemmen angewandten Schneidanschlußtechnik ist ein Abisolieren der einzelnen Leiter nicht mehr nötig, wodurch der Anschluß der Leiter an einen mit dem erfindungsgemäßen Kontakteinsatz versehenen Industriestecker wesentlich schneller durchgeführt werden kann. Dadurch ist sowohl ein einfacher Aufbau des Kontakteinsatzes als auch eine leichte Zugänglichkeit der Anschlüsse gewährleistet Durch den identischen Ausbau der beiden Anschlüsse vereinfacht sich zudem die Fertigung des Kontakteinsatzes.The contact insert is suitable for the connection of insulated conductors, since the connections are designed as cutting connections. By using the applied already in terminal blocks cutting terminal technology stripping the individual conductors is no longer necessary, whereby the connection of the conductor can be performed much faster to a provided with the contact insert according to the invention industrial connector. As a result, both a simple construction of the contact insert and easy accessibility of the connections is ensured by the identical expansion of the two terminals also simplifies the manufacture of the contact insert.

Die Schneidelemente stellen den elektrischen Kontakt der in dem Kontakteinsatz eingesteckten Leiter über jeweils eine Stromschiene mit einem Stiftkontakt oder einem Buchsenkontakt her, wobei die Betätigungsschieber jeweils relativ zu den Schneidelementen in dem Kontakteinsatz verschiebbar angeordnet sind und jeweils eine für die ankommenden isolierten Leiter vorgesehene Leiteraufnahme aufweisen. Ein isolierter Leiter braucht somit einfach nur in die Leiteraufnahme des Betätigungsschiebers eingesteckt werden, um anschließend zur Kontaktierung mit Hilfe des Betätigungsschiebers in die Schneiden des Schneidelements gedrückt zu werden. Dabei durchtrennen die Schneiden die Isolation des Leiters und kontaktieren dessen Seele, wodurch die elektrische Verbindung des Leiters mit dem Stift- oder Buchsenkontakt hergestellt wird.The cutting elements provide the electrical contact of the inserted in the contact insert conductor via a respective busbar with a pin contact or a female contact, wherein the actuating slide are each arranged displaceably relative to the cutting elements in the contact insert and each having a provided for the incoming insulated conductor conductor receiving. An insulated conductor thus simply needs only in the conductor receiving the operating slide are inserted in order then to be pressed for contacting with the aid of the actuating slide in the cutting of the cutting element. The blades sever the insulation of the conductor and contact its core, whereby the electrical connection of the conductor is made with the pin or socket contact.

Dadurch, daß der Betätigungsschieber eine Aufnahme zum Eingriff eines Hilfsmittels aufweist, kann der Betätigungsschieber besonders einfach bewegt werden, nämlich besonders einfach von einem Zustand, in dem das Einstecken eines ankommenden Leiters möglich ist, in den kontaktierten Zustand geführt werden kann. Dabei empfiehlt es sich, eine zur Führung des Hilfsmittels geeignete Betätigungshilfe vorzusehen, die als Widerlager für das Hilfsmittel dienen kann und in dem Gehäusekörper drehbar gelagert und mit ihrem einen Ende in den Betätigungsschieber eingreifen kann, so daß eine gewollte Verschiebung des Betätigungsschiebers unterstützt wird.Characterized in that the actuating slide has a receptacle for engagement of an aid, the actuating slide can be moved very easily, namely particularly easy from a state in which the insertion of an incoming conductor is possible, can be performed in the contacted state. It is advisable to provide a suitable for guiding the aid actuating aid which can serve as an abutment for the aid and rotatably mounted in the housing body and can engage with its one end in the actuating slide, so that a desired displacement of the actuating slide is supported.

Eine bevorzugte Ausführungsform des erfindungsgemäßen Kontakteinsatzes ist weiter gekennzeichnet durch mindestens eine zusätzliche Öffnung zur Aufnahme eines Prüfsteckers. Durch diese Öffnung kann die Spitze eines Prüfsteckers auf einfache Weise in das Innere des Kontakteinsatzes eingeführt werden, so daß eine Spannungsmessung durchgeführt werden kann. Vorteilhafterweise ist zu diesem Zweck ein Stromschienenabschnitt zur Einsteckrichtung des Prüfstecker hin abgebogen, so daß der eingesteckte Prüfstecker mit dem parallel verlaufenden Stromschienenabschnitt elektrischen Kontakt hat.A preferred embodiment of the contact insert according to the invention is further characterized by at least one additional opening for receiving a test plug. Through this opening, the tip of a test plug can be easily inserted into the interior of the contact insert, so that a voltage measurement can be performed. Advantageously, for this purpose, a busbar section is bent toward the plug-in direction of the test plug, so that the plugged test plug with the parallel busbar section has electrical contact.

Schließlich soll noch erwähnt sein, daß mehrere erfindungsgemäße Kontakteinsätze zu einem Kontaktblock zusammengerastet werden können, wobei benachbarte Kontakteinsätze durch eine von oben in die Kontakteinsätze einsteckbare Brücke elektrisch leitend miteinander verbindbar sind.Finally, it should be mentioned that a plurality of contact inserts according to the invention can be snapped together to form a contact block, wherein adjacent contact inserts are electrically conductively connected by a plug-in from above into the contact inserts bridge.

Im einzelnen gibt es nun eine Vielzahl von Möglichkeiten, den erfindungsgemäßen Kontakteinsatz für Industriestecker auszugestalten. Dazu wird verwiesen einerseits auf die dem Schutzanspruch 1 nachgeordneten Schutzansprüche, andererseits auf die Beschreibung bevorzugter Ausführungsbeispiele in Verbindung mit der Zeichnung.

Der in Fig. 1 dargestellte Kontakteinsatz 1 besteht zunächst aus einem Gehäusekörper 2 und aus zwei gegenüberliegenden Anschlüssen 3 zum Anschluß von zwei isolierten Leitern 4, wozu an der Oberseite 5 und der Unterseite 6 des Gehäusekörpers 2 Langlöcher 7 ausgebildet sind. Der Kontakteinsatz 1 weist zwei Stiftkontakte 8 auf, die die elektrische Verbindung des mit einem erfindungsgemäßen Kontakteinsatz 1 versehenen Industriesteckers zu einem hier nicht dargestellten Klemmadapter ermöglichen.The contact insert 1 shown in Fig. 1 initially consists of a housing body 2 and two opposite terminals 3 for connection of two insulated conductors 4, for which purpose on the top 5 and the bottom 6 of the housing body 2 slots 7 are formed. The contact insert 1 has two pin contacts 8, which enable the electrical connection of the provided with a contact insert 1 according to the invention industrial connector to a clamping adapter, not shown here.

Die Anschlüsse 3 des Kontakteinsatzes 1, die erfindungsgemäß als Schneidanschlüsse ausgebildet sind, sind bezüglich der Mittelebene M des Kontakteinsatzes 1 spiegelbildlich zueinander angeordnet. Insgesamt hat der Gehäusekörper 2 somit eine im wesentlichen rechteckige, relativ flache Form. Die als Schneidanschlüsse ausgebildeten Anschlüsse 3 weisen jeweils ein Schneidelement 9 und einen Betätigungsschieber 10 auf. Die Schneidelemente 9 sind über jeweils eine Stromschiene 11 mit einem Stiftkontakt 8 verbunden. Die Betätigungsschieber 10 weisen jeweils eine Leiteraufnahme 12 auf, die an einem Teil 13 des Betätigungsschiebers 10 ausgebildet sind, der sich einerseits unterhalb des Langloches 7 befindet, andererseits beim Verschieben des Betätigungsschiebers 10 über das Schneidelement 9 herüberragt.The terminals 3 of the contact insert 1, which are formed according to the invention as cutting connections, are arranged with respect to the center plane M of the contact insert 1 mirror images of each other. Overall, the housing body 2 thus has a substantially rectangular, relatively flat shape. The terminals 3 designed as cutting terminals each have a cutting element 9 and an actuating slide 10. The cutting elements 9 are connected via a respective busbar 11 with a pin contact 8. The actuating slide 10 each have a conductor receptacle 12 which are formed on a part 13 of the actuating slide 10, which is located on the one hand below the elongated hole 7, on the other hand protrudes when moving the actuating slide 10 via the cutting element 9.

Der Betätigungsschieber 10 ist weiter mit einer Aufnahme 14 versehen, in die ein Hilfsmittel 15, beispielsweise ein Schraubendreher, eingreifen kann. Mit einem solchen Hilfsmittel 15 kann der Betätigungsschieber 10 zum Anschließen eines isolierten Leiters 4 an den Kontakteinsatz 1 in Richtung auf das Schneidelement 9 geschoben werden. Dabei wird der elektrische Leiter 4, der in der Aufnahme 14 des Betätigungsschiebers 10 geführt wird, in Schneiden 16 des U-förmigen Schneidelements 9 gedrückt, so daß die Insolierung 17 des elektrischen Leiters 4 durchtrennt wird und dadurch die Seele 18 des Leiters 4 über das elektrisch leitende Schneidelement 9 mit der Stromschiene 11 und damit mit dem Stiftkontakt 8 verbunden wird.The actuating slide 10 is further provided with a receptacle 14, in which an aid 15, such as a screwdriver, can intervene. With such a tool 15, the actuating slide 10 can be pushed for connecting an insulated conductor 4 to the contact insert 1 in the direction of the cutting element 9. In this case, the electrical conductor 4, which is guided in the receptacle 14 of the actuating slide 10, pressed in cutting 16 of the U-shaped cutting element 9, so that the Insolierung 17 of the electrical conductor 4 is severed and thereby the soul 18 of the conductor 4 on the electrically conductive cutting element 9 is connected to the busbar 11 and thus to the pin contact 8.

Der Kontakteinsatz 1 weist noch eine Betätigungshilfe 19 auf, die in die Oberseite 5 bzw. die Unterseite 6 des Gehäusekörpers 2 eingerastet werden kann und so ausgebildet ist, daß das eine Ende 20 der Betätigungshilfe 19 in den Betätigungsschieber 10 eingreift. Das Zusammenwirken von Betätigungshilfe 19 und Betätigungsschieber 10 sowie eine vorteilhafte Ausgestaltung der Betätigungshilfe 19 sind in Fig. 2 dargestellt. Die Betätigungshilfe 19 ist in der Oberseite 5 bzw. der Unterseite 6 des Gehäusekörpers 2 drehbar gelagert und weist ein schmales Führungsstück 21 auf, welches sowohl zur Führung als auch als Widerlager für das Hilfsmittel 15 dient.The contact insert 1 still has an actuating aid 19, which can be snapped into the top 5 and the bottom 6 of the housing body 2 and is formed so that one end 20 of the actuating aid 19 engages in the actuating slide 10. The interaction of actuating aid 19 and actuating slide 10 and an advantageous embodiment of the actuating aid 19 are shown in Fig. 2. The actuating aid 19 is rotatably mounted in the upper side 5 or the underside 6 of the housing body 2 and has a narrow guide piece 21, which serves both for guiding and as an abutment for the aid 15.

Anhand von Fig. 2 soll nun im folgenden der Anschluß eines elektrischen Leiters 4 erläutert werden:The connection of an electrical conductor 4 will now be explained below with reference to FIG. 2:

Zunächst befindet sich der Betätigungsschieber 10 in seiner von dem Schneidelement 9 entfernten Stellung, so daß ein isolierter Leiter 4 durch das Langloch 7 in die Leiteraufnahme 12 des Betätigungsschiebers 10 eingeführt werden kann. Ein Hilfsmittel 15, beispielsweise ein Schraubendreher, wird in den Betätigungsschieber 10 eingesteckt, und zwar derart, daß das Hilfsmittel 15 von oben - bzw. bei dem zweiten Anschluß 3 des Kontakteinsatzes 1 von unten - durch die Betätigungshilfe 19 bzw. durch deren Führungsstück 21 soweit in den Betätigungsschieber 10 eingesteckt wird, daß die Spitze des Hilfsmittels 15 in der konisch verlaufenden Aufnahme 14 des Betätigungsschiebers 10 aufsetzt. Nun wird das Hilfsmittel 15 an seinem oberen Ende in Richtung auf die Stiftkontakte 8 bewegt, wobei sich das Hilfsmittel 15 und mit ihm auch die Betätigungshilfe 19 um den Drehpunkt D drehen. Dieser Drehpunkt D befindet sich auf Höhe des schmalen Führungsstückes 21, welches gleichzeitig als Widerlager für das Hilfsmittel 15 dient. Der Betätigungsschieber 10 wird nun zum einen direkt durch die Bewegung des Hilfsmittels 15 in Richtung auf das Schneidelement 9 geschoben, zum anderen wird diese Bewegung zusätzlich durch die in dem Betätigungsschieber 10 eingreifende Betätigungshilfe 19 unterstützt.First, the actuating slide 10 is in its position remote from the cutting element 9, so that an insulated conductor 4 can be inserted through the slot 7 in the conductor receiving 12 of the actuating slide 10. An aid 15, such as a screwdriver, is inserted into the actuating slide 10, in such a way that the aid 15 from above - or at the second terminal 3 of the contact insert 1 from below - by the actuating aid 19 or by their guide piece 21 so far is inserted into the actuating slide 10 that the tip of the aid 15 in the tapered receptacle 14 of the actuating slide 10 touches. Now the tool 15 is moved at its upper end in the direction of the pin contacts 8, wherein the aid 15 and with it also the actuating aid 19 rotate about the pivot point D. This pivot point D is at the height of the narrow guide piece 21, which also serves as an abutment for the aid 15. The actuating slide 10 is now pushed on the one hand directly by the movement of the auxiliary means 15 in the direction of the cutting element 9, on the other hand, this movement is additionally supported by the engaging in the actuating slide 10 actuating aid 19.

Durch das Aufschieben des Teils 13 des Betätigungsschiebers 10 über das Schneidelement 9 wird der Leiter 4, der in der Leiteraufnahme 11 steckt und somit die Bewegung des Betätigungsschiebers 10 mitvollzieht, in die Schneiden 16 des Schneidelements 9 gedrückt. Dabei durchtrennen die Schneiden 16 die Isolierung 17 und kontaktieren die leitende Seele 18 des elektrischen Leiters 4.By pushing the part 13 of the actuating slide 10 via the cutting element 9 of the conductor 4, which is inserted in the conductor holder 11 and thus follows the movement of the actuating slide 10, pressed into the cutting 16 of the cutting element 9. The cutting edges 16 cut through the insulation 17 and contact the conductive core 18 of the electrical conductor 4.

Die Betätigungshilfe 19 weist eine Spitze 22 auf, die einem Monteur die Anschlußstellung anzeigt, d. h. ob ein elektrischer Leiter 4 kontaktiert ist oder nicht bzw. ob ein neuer Leiter 4 eingeführt werden kann oder nicht.The actuating aid 19 has a tip 22 which indicates to a fitter the connection position, ie whether an electrical conductor 4 is contacted or not or whether a new conductor 4 can be inserted or not.

Die Oberseite 5 und die Unterseite 6 des Gehäusekörpers 2 sind an ihren den Stiftkontakten 8 abgewandten Enden 23 jeweils abgeschrägt, so daß die Leiter 4 im kontaktierten Zustand im wesentlichen in Längsrichtung des Kontakteinsatzes 1 und damit parallel zueinander umbiegbar sind, sowie dies in Fig. 1 gestrichelt dargestellt ist. Dadurch ist es möglich, die Leiter 4 einerseits zum Anschließen an den Kontakteinsatz 1 besonders einfach von oben bzw. von unten im wesentlichen senkrecht in die beiden Leiteraufnahmen 12 einzuführen, andererseits nach dem Anschließen die Leiter 4 platzsparend im nicht dargestellten Gehäuse unterzubringen.The upper side 5 and the lower side 6 of the housing body 2 are respectively beveled at their ends facing away from the pin contacts 8, so that the conductors 4 in the contacted state substantially in the longitudinal direction of the contact insert 1 and thus are parallel umbiegbar, and this in Fig. 1st is shown in dashed lines. This makes it possible, the conductor 4 on the one hand for connecting to the contact insert 1 particularly simple from above or from below to introduce substantially perpendicular to the two conductor receptacles 12, on the other hand after connecting the conductor 4 space to accommodate in the housing, not shown.

In Fig. 3 sind eine Mehrzahl zu einem Kontaktblock zusammengerastete Kontakteinsätze 1 dargestellt. Hierbei weisen die Kontakteinsätze 1, im Unterschied zu dem Ausführungsbeispiel gemäß Fig. 1, jeweils zwei zusätzliche Öffnungen 24 zur Aufnahme eines Prüfsteckers 25 auf. Um einen sicheren elektrischen Kontakt eines eingesteckten Prüfsteckers 25 zu gewährleisten, sind die beiden Stromschienen 11 jeweils zur Einsteckrichtung des Prüfsteckers 25 hin abgebogen, so daß sich der Prüfstecker 25 mit seiner Spitze an den parallel dazu verlaufenden Stromschienenabschnitt 26 anlegt. In einem geringen Abstand zu den Stromschienenabschnitten 26 ist jeweils eine Gegenfläche 27 im Gehäusekörper 2 ausgebildet, so daß ein eingesteckter Prüfstecker 25 von der Gegenfläche 27 gegen den entsprechenden Stromschienenabschnitt 26 gedrückt wird.In Fig. 3 a plurality of a contact block zusammengerastete contact inserts 1 are shown. In this case, the contact inserts 1, in contrast to the embodiment of FIG. 1, in each case two additional openings 24 for receiving a test plug 25. In order to ensure a safe electrical contact of an inserted test plug 25, the two bus bars 11 are each bent to the insertion direction of the test plug 25, so that the test plug 25 rests with its tip on the parallel thereto busbar section 26. At a small distance from the busbar sections 26, a respective mating surface 27 is formed in the housing body 2, so that an inserted test plug 25 is pressed by the mating surface 27 against the corresponding busbar section 26.

In Fig. 4 ist ein Detailausschnitt eines aus zwei Kontakteinsätzen 1 bestehenden Kontaktblocks dargestellt, anhand dessen die Funktionsweise einer in den Kontaktblock einsteckbaren Brücke 28 deutlich wird. Die Brücke 28 dient dazu, zu einem Kontaktblock zusammengerastete Kontakteinsätze 1 elektrisch leitend miteinander zu verbinden. Die in Fig. 4 dargestellte Brücke 28 besteht aus zwei U-förmigen Gabelstücken 29 und einem gemeinsamen Griff 30; sie kann mit Hilfe des gemeinsamen Griffes 30 von oben bzw. von unten in den Kontaktblock eingeschoben werden, so daß die Brücke 28 dann eine, in Fig. 4 gestrichelt dargestellte Position einnimmt. In dieser Position umfassen die einzelnen U-förmigen Gabelstücke 29 jeweils eine Stromschiene 11 eines Kontakteinsatzes 1. Somit können auf einfache Weise benachbarte Kontakteinsätze 1 gebrückt werden, d. h. auf ein gemeinsames Potential gelegt werden. Besteht der Kontaktblock aus mehr als nur aus zwei Kontakteinsätzen 1 - wie dies in Fig. 4 gezeigt ist - und besteht die Brücke 28 ebenfalls aus mehr als nur aus zwei U-förmigen Gabelstücken 29, so können entweder mehr als nur zwei benachbarte Stromschienen 11 miteinander gebrückt werden oder es können durch Herausbrechen einzelner Gabelstücke 29 einzelne Kontakteinsätze 1 beim Brücken "übersprungen" werden.FIG. 4 shows a detailed detail of a contact block consisting of two contact inserts 1, by means of which the mode of operation of a bridge 28 which can be inserted into the contact block becomes clear. The bridge 28 serves to electrically connect to a contact block zusammengerastete contact inserts 1 together. The bridge 28 shown in Figure 4 consists of two U-shaped fork pieces 29 and a common handle 30; it can be inserted by means of the common handle 30 from above or from below into the contact block, so that the bridge 28 then occupies a dashed line in FIG. 4 position shown. In this position, the individual U-shaped fork pieces 29 each comprise a busbar 11 of a contact insert 1. Thus, adjacent contact inserts 1 can be bridged in a simple manner, ie be placed on a common potential. If the contact block consists of more than just two contact inserts 1 - as shown in Fig. 4 - and the bridge 28 is also made of more than just from two U-shaped fork pieces 29, so either more than two adjacent busbars 11 can be bridged with each other or 29 single contact inserts 1 can be "jumped" by breaking out individual fork pieces 29 at the bridges.
