Description

Die Erfindung betrifft eine elektrische Anschlußbaueinheit mit einem Gehäuse und mit mindestens einem Anschluß für mindestens einen isolierten Leiter oder einen abisolierten Leiter.The invention relates to an electrical Anschlußbaueinheit with a housing and with at least one connection for at least one insulated conductor or a stripped one Ladder.

Seit vielen Jahren gibt es elektrische Anschlußbaueinheiten, insbesondere Klemmen, an die elektrische Leiter ohne vorheriges Abisolieren angeschlossen werden können. Dazu wird der isolierte Leiter in eine Leiteraufnahme der Klemme eingeführt und anschließend in ein Schneidelement gedrückt, wodurch die Isolierung des Leiters durchtrennt und die Seele des Leiters von dem Schneidelement kontaktiert wird. Dabei gibt es eine Vielzahl von Ausführungsmöglichkeiten derartiger elektrischer Klemmen zum Anschluß von nicht-abisolierten Leitern. Diese unterscheiden sich insbesondere dadurch, wie der in die Leiteraufnahme eingeführte Leiter in das Schneidelement gedrückt wird. Durch das Verwenden solcher Klemmen kann ein großer Zeitvorteil beim Anschließen von Leitern erreicht werden, da das Konfektionieren und Abisolieren des elektrischen Leiters entfällt. Im übrigen gibt es seit vielen Jahrzehnten elektrische Anschlußbaueinheiten, insbesondere Klemmen, an die abisolierte elektrische Leiter angeschlossen werden können.For many years, there are electrical connection units, in particular terminals, can be connected to the electrical conductors without prior stripping. For this purpose, the insulated conductor is inserted into a conductor receptacle of the terminal and then pressed into a cutting element, which cuts through the insulation of the conductor and the core of the conductor is contacted by the cutting element. There are There are a variety of possible embodiments of such electrical terminals for Connection of non-stripped conductors. These differ in particular by as the inserted into the ladder receiving conductor pressed into the cutting element becomes. By using such terminals can be a great time advantage in the Connecting conductors can be achieved because the assembling and stripping of the electrical conductor deleted. Incidentally, there are electrical for many decades Terminal units, in particular terminals, to the stripped electrical conductors can be connected.

Aus einem Produktkatalog der Firma WAGO Kontakttechnik GmbH ist eine elektrische Anschlußbaueinheit der eingangs beschriebenen Art bekannt. Diese elektrische Anschlußbaueinheit enthält sowohl Schneidelemente als auch Federelemente, so daß sowohl isolierte Leiter als auch abisolierte Leiter an die Anschlußbaueinheit angeschlossen werden können. Nachteilig ist bei dieser bekannten Anschlußbaueinheit jedoch, daß durch die Anordnung der Schneidelemente in einer Ebene oberhalb der Federelemente eine Anschlußbaueinheit mit relativ großen Abmessungen, insbesondere einer relativ großen Höhe entsteht.From a product catalog of the company WAGO Kontakttechnik GmbH is an electrical Terminal assembly of the type described above known. This electrical Terminal assembly includes both cutting elements and spring elements, so that both insulated conductors and stripped conductors connected to the terminal assembly can be. A disadvantage of this known terminal assembly, however, that by the arrangement of the cutting elements in a plane above the Spring elements a Anschlußbaueinheit with relatively large dimensions, in particular a relatively high altitude arises.

Schneidelement meint dabei ein die Isolation des isolierten Leiters beim Einführen des isolierten Leiters schneidendes, d. h. durchtrennendes und dann mit der Seele des Leiters kontaktierendes Kontaktelement, während Federelement für ein Kontaktelement steht, das durch Federkraft einen abisolierten Leiter kontaktiert.Cutting element means a the insulation of the insulated conductor during insertion of the insulated conductor cutting, d. H. divisive and then with the soul of Conductor contacting contact element, while spring element for a contact element stands, which contacted by spring force a stripped conductor.

Aus der EP 0 419 301 A2 ist ein selbst-abisolierender Steckverbinder zur Verbindung von elektrisch isolierten Leitern bekannt. Der bekannte Steckverbinder, der für die Verbindung eines elektrischen Leiters mit einer isolierenden Umhüllung vorgesehen ist, weist zwei Leiterelemente auf, die gegeneinander beweglich angeordnet sind. Die beiden Leiterelemente weisen jeweils einen Bereich auf, der schräg zur Längsrichtung des Steckverbinders verläuft und einen Kontaktschlitz aufweist. Die beiden Bereiche der Leiterelemente kreuzen sich, so daß sie beim Schließen einen eingeführten isolierten Leiter zwischen den beiden zueinander ausgerichteten Kontaktschlitzen einklemmen und somit die Isolierung des Leiters durch die Schneidkanten durchtrennt wird. Der Anschluß eines isolierten Leiters ist bei diesem Steckverbinder nicht vorgesehen.EP 0 419 301 A2 discloses a self-stripping connector for connection known from electrically insulated conductors. The well-known connector for the Connection of an electrical conductor provided with an insulating sheath is, has two conductor elements which are arranged to move against each other. The Both conductor elements each have an area which is oblique to the longitudinal direction the connector extends and has a contact slot. The two areas the conductor elements intersect so that they are isolated when inserted Clamp the conductor between the two aligned contact slots and thus severing the insulation of the conductor by the cutting edges becomes. The connection of an insulated conductor is not provided in this connector.

Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, eine eingangs beschriebene elektrische Anschlußbaueinheit zum Anschluß von sowohl isolierten als auch abisolierten Leitern zur Verfügung zu stellen, die nur sehr geringe Abmessungen aufweist.The present invention is therefore based on the object, an initially described electrical connection unit for the connection of both isolated as also provide stripped conductors, the very small dimensions having.

Die zuvor hergeleitete und aufgezeigte Aufgabe ist erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst. Durch die Ausbildung der Schenkel des kastenförmigen Metallteils sowohl als Schneidelement als auch als Federelement fallen das Schneidelement und das Federelement räumlich zusammen, so daß die Abmessungen der elektrischen Anschlußbaueinheit erheblich verringert werden können. Dies ist immer dann besonders wichtig, wenn nur ein sehr geringer Anschlußraum zur Verfügung steht, was insbesondere bei Verwendung einer elektrischen Anschlußbaueinheit auf einer Leiterplatte der Fall ist. Durch die ständige Verkleinerung der Leiterplatten selbst und eine Miniaturisierung der auf der Leiterplatte angeordneten Bauelemente ergibt sich auch für die auf einer Leiterplatte angeordneten elektrischen Anschlußbaueinheiten die Forderung nach sehr geringen Abmessungen. Darüber hinaus ergibt sich insbesondere in der Installationstechnik eine Vielzahl von Anwendungsfällen, in denen, bedingt durch den nur sehr geringen zur Verfügung stehenden Anschlußraum, elektrische Anschlußbaueinheiten mit sehr geringen Abmessungen erforderlich sind.The previously derived and indicated object is according to the invention with the features of claim 1. By forming the legs of the box-shaped Metal part both as a cutting element and as a spring element fall the Cutting element and the spring element spatially together, so that the dimensions the electrical connection unit can be significantly reduced. This is always especially important if only a very small connection space available stands, which in particular when using an electrical Anschlußbaueinheit on a circuit board is the case. Due to the constant reduction of printed circuit boards itself and a miniaturization of arranged on the circuit board components also results for the arranged on a circuit board electrical Anschlußbaueinheiten the demand for very small dimensions. Furthermore results in particular in the installation technology a variety of applications, in which, due to the very small available terminal space, electrical Anschlußbaueinheiten required with very small dimensions are.

Dadurch, daß das Schneidelement und das Federelement lediglich aus einem Metallteil besteht, wird zum einen die Anzahl der die elektrische Anschlußbaueinheit bildenden Bauteile verringert, zum anderen ist eine einfache und schnelle Fertigung der Anschlußbaueinheit möglich. Durch die einteilige Ausführung von Schneidelement und Federelement kann das das Schneidelement und das Federelement realisierende Metallteil einfach in das Gehäuse eingesetzt und, falls gewünscht, durch entsprechende Rastmittel in dem Gehäuse befestigt werden.Characterized in that the cutting element and the spring element only of a metal part is, on the one hand, the number of the electrical Anschlußbaueinheit forming Parts reduced, on the other hand is a simple and fast production of the connection unit possible. Due to the one-piece design of cutting element and Spring element can that the cutting element and the spring element realizing Metal part simply inserted into the housing and, if desired, by appropriate Locking means are mounted in the housing.

Durch die kastenförmige Ausbildung des Metallteils und die dadurch insgesamt kastenförmige Bauform der elektrischen Anschlußbaueinheit ist eine sehr einfache Aneinanderreihung von mehreren Anschlußbaueinheiten zu einem Anschlußblock möglich. Auch ist ein im wesentlichen kastenförmiges Metallteil sehr einfach, beispielsweise durch Ausstanzen, herstellbar.Due to the box-shaped design of the metal part and thereby total box-shaped design of the electrical connection unit is a very simple Stringing of several Anschlußbaueinheiten to a terminal block possible. Also, a substantially box-shaped metal part is very simple, for example by punching, producible.

In Fig. 1 ist eine elektrische Anschlußbaueinheit 1 mit einem Gehäuse 2 dargestellt, die insgesamt drei Anschlußmöglichkeiten aufweist. An die elektrische Anschlußbaueinheit 1 sind sowohl ein isolierter Leiter 3 als auch ein abisolierter Leiter 4 angeschlossen. Die dritte Anschlußmöglichkeit der elektrischen Anschlußbaueinheit 1 gemäß Fig. 1 ist noch frei; hier kann entweder ein isolierter Leiter 3 oder ein abisolierter Leiter 4 angeschlossen werden.In Fig. 1, an electrical terminal assembly 1 is shown with a housing 2, the has a total of three connection options. To the electrical connection unit 1, both an insulated conductor 3 and a stripped conductor 4 are connected. The third connection option of the electrical connection unit 1 according to Fig. 1 is still free; Either an insulated conductor 3 or a stripped conductor can be used here 4 are connected.

In Fig. 2 sind nun Metallteile 5 der in Fig. 1 dargestellten elektrischen Anschlußbaueinheit 1 dargestellt, also ohne das sie umgebende, in Fig. 1 dargestellte Gehäuse 2. Da die elektrische Anschlußbaueinheit 1 gemäß Fig. 1 insgesamt drei Anschlußmöglichkeiten aufweist, sind in dem Gehäuse 2 insgesamt drei identische Metallteile 5 vorhanden. Dabei ist jedes Metallteil 5 im wesentlichen kastenförmig ausgebildet und seitlich mit federnden Schenkeln 6 versehen. Die beiden freien Enden der seitlich federnden Schenkel 6 sind als Schneidkanten 7 ausgebildet. Somit übernimmt das Metallteil 5 sowohl die Funktion eines Schneidelements zum Durchtrennen der Isolierung 8 eines isolierten Leiters 3 und anschließenden Kontaktieren der Seele 9 des Leiters 3 als auch die Funktion eines Federelementes zur Kontaktierung eines abisolierten Leiters 4. Dabei sind die seitlich federnden Schenkel 6 des Metallteils 5 so ausgebildet, daß sie eine in Längserstreckung des Leiters 3 bzw. 4 schräg verlaufende Kontaktöffnung bilden und im Bereich der Schneidkanten 7 einen quer zur Längserstreckung verlaufenden, sich nach unten verjüngenden Einlaufbereich 10 für einen isolierten Leiter 3 bilden. Zur Kontaktierung eines isolierten Leiters 3 wird dieser parallel zur Längserstreckung des Metallteils 5 von oben in das Metallteil 5 gedrückt, so daß die Schneidkanten 7 die Isolierung 8 des isolierten Leiters 3 durchtrennen und die Seele 9 kontaktieren. Zur Kontaktierung eines abisolierten Leiters 4 wird dieser durch eine im Gehäuse 2 ausgebildete Öffnung 11 in Längsrichtung des Metallteils 5 in die elektrische Anschlußbaueinheit 1 eingeschoben, so daß die Seele 9 des Leiters 4 durch die von den seitlich federnden Schenkeln 6 gebildete Kontaktöffnung hindurchtritt, die federnden Schenkel 6 des Metallteils 5 auseinanderdrückt und somit von diesen kontaktiert wird.In Fig. 2 are now metal parts 5 of the electrical Anschlußbaueinheit shown in Fig. 1 1, that is, without the surrounding housing, shown in Fig. 1 housing. 2 Since the electrical Anschlußbaueinheit 1 shown in FIG. 1 a total of three connection options have, in the housing 2 a total of three identical metal parts. 5 available. In this case, each metal part 5 is formed substantially box-shaped and provided laterally with resilient legs 6. The two free ends of the laterally springy Legs 6 are formed as cutting edges 7. Thus, the metal part takes over Figure 5 shows both the function of a cutting element for severing the insulation 8 of an insulated conductor 3 and then contacting the soul 9 of the Ladder 3 and the function of a spring element for contacting a stripped Conductor 4. The laterally resilient limbs 6 of the metal part 5 are thus formed, in that they extend obliquely in the longitudinal extent of the conductor 3 and 4, respectively Form contact opening and in the region of the cutting edges 7 a transverse to the longitudinal extent extending, tapering down the inlet region 10 for a form insulated conductor 3. For contacting an insulated conductor 3 of this pressed in parallel to the longitudinal extent of the metal part 5 from above into the metal part 5, so that the cutting edges 7 sever the insulation 8 of the insulated conductor 3 and contact the soul 9. For contacting a stripped conductor 4 this by an opening 11 formed in the housing 2 in the longitudinal direction of the metal part 5 inserted into the electrical connection assembly 1, so that the soul 9 of the conductor 4 passes through the contact opening formed by the laterally resilient legs 6, the resilient leg 6 of the metal part 5 presses apart and thus contacted by them.

An dem der Öffnung 11 des Gehäuses 2 abgewandten Ende des Metallteils 5 ist eine nach oben offene Metallasche 12 ausgebildet. Die Metallasche 12 dient in erster Linie dazu, das Metallteil 5 in dem Gehäuse 2 zu fixieren. Hierzu sind an den seitlichen Innenwänden 13 des Gehäuses 2 des weiteren zwei Rastnasen 14 ausgebildet, unter die die Enden 15 der Metallasche 12 einrasten. Da auch die Metallasche 12 federnd ausgeführt ist, kann das Metallteil 5 auf einfache Art und Weise von oben in das Gehäuse 2 hineingedrückt werden. Als weitere axiale Befestigungs- und Positionierungshilfe sind an den seitlichen Innenwänden 13 des Gehäuses 2 Befestigungsstege 16 ausgebildet.
