Description

Die Erfindung geht aus von einem elektrischen Leiteranschlusselement zur Kontaktierung eines elektrischen Leiters an einer Leiterkarte oder einem elektrischen Gerät nach dem Oberbegriff des unabhängigen Anspruchs 1.The invention is based on an electrical conductor connection element for contacting an electrical conductor on a circuit card or an electrical device according to the preamble of independent claim 1.

Derartige Leiteranschlusselemente werden benötigt, um elektrische Leiter, Kabel oder Litzen elektrisch mit Bauteilen, Geräten oder anderen elektrischen Einrichtungen zu verbinden. Dabei ist eine sichere elektrische und mechanische Verbindung des Leiters, des Kabels oder der Litze mit der Einrichtung zu gewährleisten. Die elektrische Kontaktierung wird meist über ein mechanisches Kontaktelement hergestellt. Dabei ist das Kontaktelement als Feder- oder Schraubkontakt ausgebildet. Über die Feder- oder Schraubkraft kann der Leiter oder das Kabel mechanisch und damit auch elektrisch angeschlossen werden.Such conductor connection elements are required to electrically connect electrical conductors, cables or strands to components, devices or other electrical devices. A secure electrical and mechanical connection between the conductor, the cable or the stranded wire and the device must be ensured. The electrical contact is usually made via a mechanical contact element. The contact element is designed as a spring or screw contact. The conductor or the cable can be connected mechanically and thus also electrically via the spring or screw force.

Stand der TechnikState of the art

Die DE 10 2006 018 129 C5 zeigt eine Federkraftklemme mit zumindest einer in einem Gehäuse angeordneten Schenkelfeder. Dabei ist die Schenkelfeder zur Kontaktierung eines eingeführten Leiters ausgelegt und mit Kontaktpins der Federkraftklemme elektrisch verbunden. Über die Kontaktpins kann die Federkraftklemme auf einer Leiterplatte kontaktiert und somit der angeschlossene Leiter mit der Leiterplatte elektrisch verbunden werden.The DE 10 2006 018 129 C5 shows a spring-loaded terminal with at least one leg spring arranged in a housing. The leg spring is designed to make contact with an inserted conductor and is electrically connected to the contact pins of the spring-loaded terminal. The spring-loaded terminal on a circuit board can be contacted via the contact pins and the connected conductor can thus be electrically connected to the circuit board.

Aus der DE 10 2010 048 698 A1 ist eine elektrische Verbindungsklemme mit einem Isolierstoffgehäuse und mit mindestens einem Federklemmanschluss in dem Isolierstoffgehäuse bekannt. Der Federklemmanschluss ist mit einem Steckanschluss elektrisch verbunden, welcher als Lötstift oder Lötpad ausgebildet ist. Über den Steckanschluss kann die elektrische Verbindungsklemme auf beispielsweise einem Gehäuse oder Gerät elektrisch verbunden werden. Der Federklemmanschluss im Isolierstoffgehäuse ist zur reversiblen Kontaktierung eines elektrischen Leiters vorgesehen.From the DE 10 2010 048 698 A1 an electrical connection terminal with an insulating housing and with at least one spring clamp connection in the insulating housing is known. The spring clamp connection is electrically connected to a plug connection, which is designed as a soldering pin or soldering pad. The electrical connection terminal can be electrically connected to a housing or device, for example, via the plug connection. The spring clamp connection in the insulating housing is provided for reversible contact with an electrical conductor.

Aus der Druckschrift US 2008/0267359 A1 ist ein kompakter Teststecker für Telefonanlagen bekannt, mit dem über eine trennbare Schaltverbindung ein Signal trenn- und abgreifbar ist.From the pamphlet US 2008/0267359 A1 a compact test plug for telephone systems is known, with which a signal can be separated and tapped via a separable switch connection.

Die Druckschrift DE 10 2011 105 157 offenbart ein elektrisches Verbindungsmodul mit unterbrechbarem Stromkreis sowie ein Verfahren zum Erfassen einer Stromstärke.The pamphlet DE 10 2011 105 157 discloses an electrical interconnect module with an interruptible circuit and a method for detecting an amperage.

Das Verbindungsmodul besitzt ein Modulgehäuse, das ein erstes elektrisches Anschlussterminal mit einem ersten Anschlusspol und einem zweiten Anschlusspol umfasst. Weiterhin besitzt das Verbindungsmodul ein Modulelement mit einem zweiten elektrischen Anschlussterminal, das ein erstes Anschlusspol und ein zweites Anschlusspol umfasst, und ein drittes elektrischen Anschlussterminal, das ein erstes Anschlusspol und ein zweites Anschlusspol umfasst. Außerdem beistzt das Verbindungsmodul einen separaten Prüfkanal für die Aufnahme einer Prüfspitze, wobei das erste elektrische Anschlussterminal mit dem dritten elektrischen Anschlussterminal elektrisch über das zweite elektrische Anschlussterminal verbindbar ist.The connection module has a module housing which comprises a first electrical connection terminal with a first connection pole and a second connection pole. Furthermore, the connection module has a module element with a second electrical connection terminal, which comprises a first connection pole and a second connection pole, and a third electrical connection terminal, which comprises a first connection pole and a second connection pole. In addition, the connection module has a separate test channel for receiving a test probe, the first electrical connection terminal being electrically connectable to the third electrical connection terminal via the second electrical connection terminal.

Bei bestehender elektrischer Verbindung zwischen dem ersten Anschlusspol des ersten Anschlussterminals und dem ersten Anschlusspol des dritten Anschlussterminals ist die elektrische Verbindung zwischen dem zweiten Anschlusspol des ersten Anschlussterminals und dem zweiten Anschlusspol des dritten Anschlussterminals trennbar. Der Prüfkanal dient zum elektrischen Kontaktieren des zweiten Anschlusspols des ersten Anschlussterminals mittels der Prüfspitze bei bestehender elektrischer Verbindung zwischen dem ersten Anschlusspol des ersten Anschlussterminals und dem ersten Anschlusspol des dritten Anschlussterminals und bei getrennter elektrischer Verbindung zwischen dem zweiten Anschlusspol des ersten Anschlussterminals und dem zweiten Anschlusspol des dritten Anschlussterminals.If there is an electrical connection between the first connection pole of the first connection terminal and the first connection pole of the third connection terminal, the electrical connection between the second connection pole of the first connection terminal and the second connection pole of the third connection terminal can be separated. The test channel is used to make electrical contact with the second connection pole of the first connection terminal by means of the test probe when there is an electrical connection between the first connection pole of the first connection terminal and the first connection pole of the third connection terminal and when the electrical connection is separated between the second connection pole of the first connection terminal and the second connection pole of the third connection terminals.

Nachteilig wirkt sich bei den aus dem Stand der Technik bekannten Leiteranschlusselementen aus, dass keine fehlerfreie Prüfung des Kontakt- und Anschlussstelle des Leiters mit dem Leiteranschlusselement, welches zur Kontaktierung eines elektrischen Leiters an einer Leiterkarte geeignet ist, möglich ist. So sind derartige Leiteranschlusselemente meist bereits an einem Gerät oder einer Leiterplatte verbaut, bevor ein elektrischer Leiter oder ein elektrisches Kabel daran angeschlossen wird. Soll nun die Kontaktstelle zwischen Leiteranschlusselement und Leiter auf ihre elektrischen Eigenschaften hin überprüft werden, wird das Ergebnis immer durch die Bauteile und elektrische Elemente des Gerätes oder der Leiterplatte verfälscht, auf welcher das Leiteranschlusselement montiert ist, da das Leiteranschlusselement bereits elektrisch damit verbunden ist. Eine Messung oder Überprüfung der isolierten Kontaktstelle oder nur des Leiteranschlusselements mit angeschlossenem Kabel ist nicht möglich.A disadvantage of the conductor connection elements known from the prior art is that it is not possible to check the contact and connection point of the conductor with the conductor connection element, which is suitable for contacting an electrical conductor on a circuit card, without errors. Such conductor connection elements are usually already installed on a device or a circuit board before an electrical conductor or an electrical cable is connected to it. If the contact point between the conductor connection element and the conductor is to be checked for its electrical properties, the result is always falsified by the components and electrical elements of the device or the circuit board on which the conductor connection element is mounted, since the conductor connection element is already electrically connected to it. It is not possible to measure or check the insulated contact point or just the conductor connection element with the cable connected.

AufgabenstellungTask

Der Erfindung liegt daher die Aufgabe zugrunde, ein Leiteranschlusselement vorzustellen, welches eine elektrische Messung der Anschlussstelle zwischen Leiteranschlusselement und angeschlossenem Kabel ermöglicht. Dabei soll eine Verfälschung der Messung durch weitere elektrische Elemente, welche bereits mit dem Leiteranschlusselement verbunden sind, ausgeschlossen werden.The invention is therefore based on the object of presenting a conductor connection element which enables electrical measurement of the connection point between the conductor connection element and the connected cable. A falsification of the measurement due to further electrical elements which are already connected to the conductor connection element should be excluded.

Die Aufgabe wird durch die Merkmale des unabhängigen Anspruchs 1 gelöst.The object is achieved by the features of independent claim 1.

Bei der Erfindung handelt es sich um ein elektrisches Leiteranschlusselement, welches aus einem Kontaktträger, zumindest einem darin aufgenommenen ersten Kontaktelement und zumindest einem mit dem ersten Kontaktelement verbundenen zweiten Kontaktelement gebildet wird. Das zweite Kontaktelement ist bereichsweise im Kontaktträger aufgenommen und bereichsweise außerhalb des Kontaktträgers angeordnet. Außerhalb des Kontaktträgers bildet das zweite Kontaktelement einen zweiten Anschlussbereich welcher zur elektrischen Kontaktierung des Leiteranschlusselements vorgesehen ist. Der zweite Anschlussbereich kann so z.B. auf einer Leiterplatte aufgelötet werden, in eine Leiterplatte eingepresst oder auf andere, elektrisch leitende Art angebunden werden. Dafür kann der zweite Anschlussbereich des zweiten Kontaktelements beispielsweise als sogenannter Press-In-Kontakt, zum direkten Einpressen in ein Kontaktloch einer Leiterplatte ausgebildet sein. Alternativ wäre auch ein Lötkontakt zum Auflöten des zweiten Anschlussbereichs denkbar. Der Kontaktträger ist bevorzugt aus einem elektrisch isolierenden Material, wie zum Beispiel einem Polymer gefertigt.The invention is an electrical conductor connection element, which consists of a contact carrier, at least one first contact element received therein and at least one with the first contact element connected second contact element is formed. The second contact element is received in areas in the contact carrier and is arranged in areas outside the contact carrier. Outside the contact carrier, the second contact element forms a second connection area which is provided for making electrical contact with the conductor connection element. The second connection area can for example be soldered onto a printed circuit board, pressed into a printed circuit board or connected in some other electrically conductive way. For this purpose, the second connection area of the second contact element can be designed, for example, as a so-called press-in contact, for direct pressing into a contact hole of a printed circuit board. Alternatively, a soldering contact for soldering on the second connection area would also be conceivable. The contact carrier is preferably made of an electrically insulating material, such as a polymer.

Dabei ist kann das erste Kontaktelement als Federkontakt oder Schraubkontakt ausgebildet sind. Je nach Anwendung und Einsatzgebiet können hier unterschiedliche, aus dem Stand der Technik bekannte Kontaktierungsarten verwendet werden. Häufig werden bei derartigen Leiteranschlusselementen sogenannte Käfigzugfedern oder Push-In-Kontakte eingesetzt, da diese zur besonders einfachen Montage und Demontage eines Kabels oder einer Litze geeignet sind.The first contact element received in the contact carrier is provided for mechanical and electrical contacting of an electrical conductor, cable or a stranded wire. The first contact element can be designed as a spring contact or a screw contact. Depending on the application and area of use, different types of contact known from the prior art can be used here. So-called cage tension springs or push-in contacts are often used in such conductor connection elements, since these are suitable for particularly simple assembly and disassembly of a cable or a stranded wire.

Um ein Kabel, einen Leiter oder eine Litze mit dem ersten Kontaktelement zu verbinden, ist im Kontaktträger eine Leiteraufnahmeöffnung ausgebildet. Diese Leiteraufnahmeöffnung ermöglicht den auf das im Kontaktträger angeordnete erste Kontaktelement zuzugreifen. Ein Leiter, eine Litze oder ein Kabel kann durch die Leiteraufnahmeöffnung in den Kontaktträger geführt und dort mit dem ersten Kontaktelement verbunden werden. Bekannte Ausführungsformen von Leiteranschlusselementen sehen vor, entweder eine weitere Öffnung im Kontaktträger auszubilden, oder die Leiteraufnahmeöffnung so groß zu gestalten, dass ein Hilfsmittel wie z.B. ein Schraubendreher in den Kontaktträger eingeführt werden kann um damit den ersten Anschlussbereich des ersten Kontaktelements zu öffnen und ein angeschlossenes Kabel, Leiter oder Litze zu lösen.In order to connect a cable, a conductor or a stranded wire to the first contact element, a conductor receiving opening is formed in the contact carrier. This conductor receiving opening enables access to the first contact element arranged in the contact carrier. A conductor, a stranded wire or a cable can be passed through the conductor receiving opening into the contact carrier and connected there to the first contact element. Known embodiments of conductor connection elements provide either to form a further opening in the contact carrier or to make the conductor receiving opening so large design so that an aid such as a screwdriver can be inserted into the contact carrier in order to open the first connection area of the first contact element and to loosen a connected cable, conductor or stranded wire.

Erfindungsgemäß weist das elektrische Leiteranschlusselement eine Trennstelle auf. Die Trennstelle ist im Kontaktträger angeordnet und dafür vorgesehen, die leitende Verbindung zwischen dem ersten Kontaktelement und dem zweiten Kontaktelement elektrisch zu trennen. Das heißt, dass das Trennelement die elektrische Verbindung vom ersten Kontaktelement und dem zweiten Kontaktelement öffnet, so dass kein Strom mehr fließen kann. Die Trennstelle ist zwischen einem ersten Kontaktbereich des ersten Kontaktelements und einem zweiten Kontaktbereich des zweiten Kontaktelements gebildet.According to the invention, the electrical conductor connection element has a separation point. The separation point is arranged in the contact carrier and is intended to electrically separate the conductive connection between the first contact element and the second contact element. This means that the separating element opens the electrical connection between the first contact element and the second contact element, so that no more current can flow. The separation point is formed between a first contact area of the first contact element and a second contact area of the second contact element.

Das erste Kontaktelement weist also einen ersten Kontaktbereich auf und das zweite Kontaktelement einen zweiten Kontaktbereich. Der erste Kontaktbereich und der zweite Kontaktbereich stehen in mechanischem und elektrischem Kontakt, so dass Strom vom ersten Kontaktelement zum zweiten Kontaktelement fließen kann.The first contact element thus has a first contact area and the second contact element has a second contact area. The first contact area and the second contact area are in mechanical and electrical contact, so that current can flow from the first contact element to the second contact element.

Die Trennstelle ist somit als elektrischer Schalter zu sehen, welcher die Verbindung vom ersten Kontaktelement und dem zweiten Kontaktelement öffnet. Das heißt, die Trennstelle ist ein elektrischer Öffner, also ein mechanischer Trennschalter. Dafür weist die Trennstelle zumindest einen beweglichen Teil auf, welcher dafür ausgelegt ist, die elektrische Verbindung zu Öffnen. Der bewegliche Teil der Trennstelle ist dabei vorzugweise ein federelastischer Bereich, der durch das Einbringen einer Kraft ausgelenkt werden kann, bis die Trennstelle geöffnet ist. Bei Entfernen der Kraft federt der bewegliche Teil wieder in seine Ausgangslager zurück und schließt die Trennstelle. Bevorzugt ist der erste Kontaktbereich des ersten Kontaktelements aus einem federelastischen Material hergestellt und bildet so den beweglichen Teil der Trennstelle.The separation point can thus be seen as an electrical switch which opens the connection between the first contact element and the second contact element. This means that the isolating point is an electrical break contact, i.e. a mechanical isolating switch. For this purpose, the separation point has at least one movable part which is designed to open the electrical connection. The movable part of the separation point is preferably a resilient area that can be deflected by the application of a force until the separation point is opened. When the force is removed, the moving part springs back into its original bearing and closes the separation point. The first contact area of the first contact element is preferred made of a resilient material and thus forms the moving part of the separation point.

Der Kontaktträger weist eine Prüföffnung auf. Durch die Prüföffnung ist ein Zugriff auf das Innere des Kontaktträgers möglich. Erfindungsgemäß ist die Trennstelle im Kontaktträger an der Prüföffnung angeordnet. Das heißt, dass durch die Prüföffnung ein Zugriff auf die im Kontaktträger befindliche Trennstelle ermöglicht ist. Mit einem entsprechenden Hilfsmittel, zum Beispiel einem Dorn oder einem Prüfstift kann durch die Prüföffnung die Trennstelle betätigt und die elektrische Verbindung zwischen ersten Kontaktelement und dem zweiten Kontaktelement geöffnet werden.The contact carrier has a test opening. Access to the interior of the contact carrier is possible through the test opening. According to the invention, the separation point is arranged in the contact carrier at the test opening. This means that access to the separation point located in the contact carrier is made possible through the test opening. With a corresponding aid, for example a mandrel or a test pin, the separation point can be actuated through the test opening and the electrical connection between the first contact element and the second contact element can be opened.

Der bewegliche Teil der Trennstelle ist am ersten Kontaktelement vorgesehen. Dadurch kann mit einem Prüfstift durch die Prüföffnung der bewegliche Teil der Trennstelle betätigt und dadurch die Trennstelle geöffnet werden. Da der bewegliche Teil jedoch weiterhin mit dem ersten Anschlussbereich elektrisch verbunden ist, kann so die erfindungsgemäße Aufgabe gelöst und eine Messung der Kontaktierung eines angeschlossenen Kabels, Leiters oder eine Litze mit dem ersten Kontaktbereich des ersten Kontaktelements vorgenommen werden. Durch weitere Bauteile oder elektrische Elemente, die über den zweiten Anschlussbereich des zweiten Kontaktelements mit dem Leiteranschlusselement verbunden sind, kann so eine Messung der Kontaktstelle nicht verfälscht werden.The movable part of the separation point is provided on the first contact element. As a result, the movable part of the separation point can be actuated with a test pin through the test opening, thereby opening the separation point. However, since the movable part is still electrically connected to the first connection area, the object according to the invention can be achieved and the contacting of a connected cable, conductor or strand with the first contact area of the first contact element can be measured. A measurement of the contact point cannot be falsified by further components or electrical elements that are connected to the conductor connection element via the second connection area of the second contact element.

Durch die erfindungsgemäßen Merkmale kann das elektrische Leiteranschlusselement zwei Zustände aufweisen: einen ersten, geschlossenen Betriebszustand und einen zweiten, geöffneten Prüfzustand. Im ersten, geschlossenen Betriebszustand ist die Trennstelle geschlossen. Das erste Kontaktelement hat eine elektrische Verbindung mit dem zweiten Kontaktelement. Im zweiten, geöffneten Prüfzustande ist beispielsweise ein Prüfstift durch die Prüföffnung in den Kontaktträger eingeführt. Der Prüfstift betätigt den beweglichen Teil der Trennstelle und öffnet diese. Eine elektrische Verbindung zwischen ersten Kontaktelement und zweiten Kontaktelement ist nicht vorhanden. Dafür kann mit dem Prüfstift die elektrische Kontaktierung eines angeschlossenen Kabels mit dem ersten Kontaktelement überprüft werden.As a result of the features according to the invention, the electrical conductor connection element can have two states: a first, closed operating state and a second, open test state. In the first, closed operating state, the separation point is closed. The first contact element has an electrical connection with the second contact element. In the second, open test state, for example, a test pin is inserted through the test opening into the contact carrier. The test pen actuates the moving part of the separation point and opens it. There is no electrical connection between the first contact element and the second contact element. For this purpose, the electrical contact between a connected cable and the first contact element can be checked with the test pin.

Eine spezielle Ausführungsform sieht vor, in dem Kontaktträger mehrere erste und zweite Kontaktelemente aufzunehmen. Entsprechend sind in dem Kontaktträger auch mehrere Trennstellen vorhanden. So kann jedes erste Kontaktelement und das damit verbundene Kabel, Leiter oder Litze einzeln entsprechend der vorliegenden Erfindung überprüft werden.A special embodiment provides for a plurality of first and second contact elements to be accommodated in the contact carrier. Correspondingly, there are also several separation points in the contact carrier. In this way, each first contact element and the cable, conductor or strand connected to it can be checked individually in accordance with the present invention.

Die Figuren enthalten teilweise vereinfachte, schematische Darstellungen. Zum Teil werden für gleiche, aber gegebenenfalls nicht identische Elemente identische Bezugszeichen verwendet. Verschiedene Ansichten gleicher Elemente könnten unterschiedlich skaliert sein.The figures contain partially simplified, schematic representations. In some cases, identical reference symbols are used for identical, but possibly not identical elements. Different views of the same elements could be scaled differently.

Die Figur 1 zeigt einen ersten, geschlossenen Betriebszustand eines elektrischen Leiteranschlusselements 1 in Schnittdarstellung. Das Leiteranschlusselement 1 wird von einem Kontaktträger 2 gebildet, welcher am Ende einer Leiterkarte 30 auf deren Oberfläche angeordnet ist. Ein Kabel 20 ist mit dem Leiteranschlusselement 1 verbunden und von rechts in den Kontaktträger 2 eingeführt. Dafür ist im Kontaktträger 2 eine Leiteraufnahmeöffnung 7 eingeformt, durch welche das Kabel 20 hier von rechts in den Kontaktträger 2 eingebracht werden kann.The Figure 1 shows a first, closed operating state of an electrical conductor connection element 1 in a sectional illustration. The conductor connection element 1 is formed by a contact carrier 2 which is arranged at the end of a circuit card 30 on the surface thereof. A cable 20 is connected to the conductor connection element 1 and introduced into the contact carrier 2 from the right. For this purpose, a conductor receiving opening 7 is formed in the contact carrier 2, through which the cable 20 can be introduced into the contact carrier 2 from the right.

Im Kontaktträger 2 des Leiteranschlusselements 1 ist ein erstes Kontaktelement 3 angeordnet. Das erste Kontaktelement 3 ist im Inneren des Kontaktträgers 2 vorgesehen und reicht in den rechten Bereich in welchem auch das Kabel 20 durch die Leiteraufnahmeöffnung 7 eingeführt ist. Im rechten Bereich bildet das das erste Kontaktelement 3 einen ersten Anschlussbereich 3.1 aus. In den ersten Anschlussbereich 3.1 ist über die Leiteraufnahmeöffnung 7 das Kabel 20 eingeführt und angeschlossen. Der erste Anschlussbereich 3.1 des ersten Kontaktelements 3 ist n diesem Ausführungsbeispiel als Käfigzugfeder, sogenannte Cage Clamp ausgeführt.A first contact element 3 is arranged in the contact carrier 2 of the conductor connection element 1. The first contact element 3 is provided in the interior of the contact carrier 2 and extends into the right-hand area in which the cable 20 is also inserted through the conductor receiving opening 7. In the right area, the first contact element 3 forms a first connection area 3.1. The cable 20 is inserted and connected into the first connection area 3.1 via the conductor receiving opening 7. In this exemplary embodiment, the first connection area 3.1 of the first contact element 3 is designed as a cage clamp spring, a so-called cage clamp.

Das erste Kontaktelement 3 ist im Kontaktträger 2 mit einem zweiten Kontaktelement 4 verbunden. Das zweite Kontaktelement 4 kontaktiert mit einem Ende im Inneren des Kontaktträgers 2 das erste Kontaktelement 3. Das zweite Ende des zweiten Kontaktelements 4 bildet außerhalb des Kontaktträgers 2 einen zweiten Anschlussbereich 4.1. Der zweite Anschlussbereich 4.1 ist in der Leiterkarte 30 aufgenommen und elektrisch mit dieser verbunden. Das Leiteranschlusselement 1 stellt somit in dem gezeigten, ersten, geschlossenen Betriebszustand eine elektrische Verbindung zwischen dem angeschlossenen Kabel 20 und der Leiterkarte 30 her.The first contact element 3 is connected to a second contact element 4 in the contact carrier 2. The second contact element 4 also makes contact one end inside the contact carrier 2, the first contact element 3. The second end of the second contact element 4 forms a second connection area 4.1 outside the contact carrier 2. The second connection area 4.1 is received in the printed circuit card 30 and is electrically connected to it. The conductor connection element 1 thus establishes an electrical connection between the connected cable 20 and the circuit card 30 in the first, closed operating state shown.

Im Kontaktträger 2 ist eine weitere Öffnung, eine Prüföffnung 8 oberhalb des ersten Kontaktelements 3 vorgesehen. Die Prüföffnung 8 ermöglicht den Zugriff auf einen ersten Kontaktbereich 3.2 des ersten Kontaktelements 3 von außerhalb des Kontaktträgers 2. Direkt unter der Prüföffnung 8 ist erfindungsgemäß eine Trennstelle 6 vorgesehen. Die Trennstelle 6 wird durch den ersten Kontaktbereich 3.2 des ersten Kontaktelements 3 zusammen mit einem zweiten Kontaktbereich 4.2 des zweiten Kontaktelements gebildet. Der ersten Kontaktbereich 3.2 und der zweite Kontaktbereich 4.2 berühren sich und sind somit mechanisch und elektrisch verbunden.A further opening, a test opening 8, is provided in the contact carrier 2 above the first contact element 3. The test opening 8 enables access to a first contact area 3.2 of the first contact element 3 from outside the contact carrier 2. According to the invention, a separation point 6 is provided directly under the test opening 8. The separation point 6 is formed by the first contact area 3.2 of the first contact element 3 together with a second contact area 4.2 of the second contact element. The first contact area 3.2 and the second contact area 4.2 touch one another and are thus mechanically and electrically connected.

Der zweite Kontaktbereich 3.2 des ersten Kontaktelements 3 ist zumindest bereichsweise beweglich ausgeführt. Dabei ist der Bereich der Trennstelle 6 federelastisch ausgebildet und fungiert so als Schalter, speziell als Öffnungs-Schalter. So können das erste Kontaktelement 3 und des zweite Kontaktelement 4 an der Trennstelle 6 durch eine flexible Verformung des ersten Kontaktbereichs 3.2 geöffnet werden. Im dargestellten, geschlossenen Betriebszustand des Leiteranschlusselements 1 federt der bewegliche Teil des ersten Kontaktbereichs 3.2 so nach oben, dass die Trennstelle 6 geschlossen ist.The second contact area 3.2 of the first contact element 3 is designed to be movable at least in certain areas. The area of the separation point 6 is designed to be resilient and thus functions as a switch, specifically as an opening switch. Thus, the first contact element 3 and the second contact element 4 can be opened at the separation point 6 by flexible deformation of the first contact area 3.2. In the illustrated, closed operating state of the conductor connection element 1, the movable part of the first contact area 3.2 springs upward so that the separation point 6 is closed.

In der Figur 2 ist ein zweiter, geöffneter Prüfzustand eines Leiteranschlusselements 1 in Schnittdarstellung gezeigt. In diesem Prüfzustand ist die Trennstelle 6 geöffnet und somit die elektrische Verbindung des ersten Kontaktelements 3 und des zweiten Kontaktelements 4 getrennt.In the Figure 2 a second, open test state of a conductor connection element 1 is shown in a sectional illustration. In this test state, the separation point 6 is open and thus the electrical connection of the first contact element 3 and the second contact element 4 is separated.

In die Prüföffnung 8 ist ein Prüfstift eingeführt. Der Prüfstift ragt durch die Prüföffnung 8 in den Kontaktträger 2 bis an die Trennstelle 6. Durch den Prüfstift wird der bewegliche Teil der Trennstelle 6 reversibel ausgelenkt und nach unten gedrückt. Durch die flexible Verformung des ersten Anschlussbereichs 3.2 an der Trennstelle 6 werden die das erste Kontaktelement 3 und das zweite Kontaktelement 4 getrennt. Die elektrische Verbindung zwischen dem ersten Kontaktelement 3 und dem zweiten Kontaktelement 4 ist getrennt.A test pin is inserted into the test opening 8. The test pin protrudes through the test opening 8 into the contact carrier 2 up to the separation point 6. The movable part of the separation point 6 is reversibly deflected and pressed down by the test pin. Due to the flexible deformation of the first connection area 3.2 at the separation point 6, the first contact element 3 and the second contact element 4 are separated. The electrical connection between the first contact element 3 and the second contact element 4 is separated.

Gleichzeitig kann mit dem Prüfstift an der Trennstelle 6 eine Messung des Kontaktelements 3 mit dem angeschlossenen Kabel 20 vorgenommen werden. Dabei wird die Messung nicht durch elektrische Bauteile oder Spannungen beeinflusst die über die Leiterkarte 30 am zweiten Anschlussbereich 4.1 des zweiten Kontaktelements 4 anliegen.At the same time, a measurement of the contact element 3 with the connected cable 20 can be carried out with the test pin at the separation point 6. The measurement is not influenced by electrical components or voltages that are applied to the second connection area 4.1 of the second contact element 4 via the printed circuit card 30.

Bei Entfernen des Prüfstifts aus der Prüföffnung 8 federt der bewegliche Teil des ersten Kontaktbereichs 3.2 wieder nach oben und schließt den Kontakt der Trennstelle 6.When the test pin is removed from the test opening 8, the movable part of the first contact area 3.2 springs up again and closes the contact of the separation point 6.

Die Figuren 3a, 3b, 4a und 4b zeigen ein zweites Ausführungsbeispiel der vorliegenden Erfindung. Dabei zeigen die Figuren 3a und 4a je eine Schnittdarstellung durch das elektrische Leiteranschlusselement 1. Die Figuren 3b und 4b zeigen je eine weitere Schnittdarstellung, wobei der Schnitt um 90° gedreht durch das elektrische Leiteranschlusselement 1 gelegt ist. Die Figuren 3a, 3b zeigen das elektrische Leiteranschlusselement 1 in einem ersten, geschlossenen Betriebszustand, während das elektrische Leiteranschlusselement 1 in den Figuren 4a, 4b in einem zweiten, geöffneten Prüfzustand dargestellt ist.The Figures 3a, 3b , 4a and 4b show a second embodiment of the present invention. They show Figures 3a and 4a each a sectional view through the electrical conductor connection element 1. The Figures 3b and 4b each show a further sectional view, the section being rotated by 90 ° through the electrical conductor connection element 1. The Figures 3a, 3b show the electrical conductor connection element 1 in a first, closed operating state, while the electrical conductor connection element 1 in FIG Figures 4a, 4b is shown in a second, open test state.

In diesem zweiten Ausführungsbeispiel ist der erste Anschlussbereich 3.1 des ersten Kontaktelements 3 als sogenannter Push-In-Kontakt ausgeführt. In diesen kann ein elektrischer Leiter direkt eingeführt und angeschlossen werden. Das erste Kontaktelement 3 weist in diesem Ausführungsbeispiel zwei, sich gegenüberstehende erste Kontaktbereiche 3.2 auf. Zwischen den ersten Kontaktbereichen 3.2 ist der zweite Kontaktbereich 4.2 des zweiten Kontaktelements 4 angeordnet. Das zweite Kontaktelement 4 ist senkrecht zum ersten Kontaktelement 3 ausgerichtet und bildet unterhalb des Kontaktträgers 2 den zweiten Anschlussbereich 4.1.In this second exemplary embodiment, the first connection area 3.1 of the first contact element 3 is designed as a so-called push-in contact. In an electrical conductor can be inserted and connected directly. In this exemplary embodiment, the first contact element 3 has two opposing first contact areas 3.2. The second contact area 4.2 of the second contact element 4 is arranged between the first contact areas 3.2. The second contact element 4 is oriented perpendicular to the first contact element 3 and forms the second connection area 4.1 below the contact carrier 2.

In dem, in den Figuren 4a, 4b gezeigten zweiten, geöffneten Prüfzustand ist über die Prüföffnung 8 ein Prüfstift in den Kontaktträger 2 eingeführt. Der Prüfstift ist zwischen den beiden ersten Kontaktbereichen 3.2 des ersten Kontaktelements 3 angeordnet, so dass die beiden ersten Kontaktbereiche 3.2 durch den Prüfstift auseinander gespreizt werden. Dafür ist der Prüfstift in seiner Stärke so ausgelegt, dass durch ihn eine ausreichende Spreizung, d.h. seitliche Bewegung der beiden ersten Kontaktbereiche 3.2 weg vom zweiten Kontaktbereich 4.2 möglich ist. Durch die ausgelenkten ersten Kontaktbereiche 3.2, weg vom zweiten Kontaktbereich 4.2 wird deren gegenseitiger, mechanischer und elektrischer Kontakt gelöst und so die zwei Kontaktstellen 6 geöffnet.In that, in the Figures 4a, 4b The second, open test state shown, a test pin is inserted into the contact carrier 2 via the test opening 8. The test pin is arranged between the two first contact areas 3.2 of the first contact element 3, so that the two first contact areas 3.2 are spread apart by the test pin. For this purpose, the strength of the test pin is designed in such a way that it allows sufficient spreading, ie lateral movement of the two first contact areas 3.2 away from the second contact area 4.2. Due to the deflected first contact areas 3.2, away from the second contact area 4.2, their mutual mechanical and electrical contact is released and the two contact points 6 are thus opened.
