Description

Die Erfindung betrifft eine Reihenklemme nach dem Oberbegriff des Anspruches 1.The invention relates to a terminal block according to the preamble of claim 1.

Eine gattungsgemäße Reihenklemme ist aus der DE-A-37 108 96 bekannt. Derartige Reihenklemmen und Anschlußvorrichtungen erlauben das Kontaktieren der Leiter in der sogenannten IDC-Technik, bei welcher Schneiden der Anschlußvorrichtung die Isolierung des Leiters durchtrennen, woraufhin in einem Kontaktierungsbereich das Kontaktieren der Leiutungsadern erfolgt. Ein manuelles Abisolieren des Leiters mit einem speziellen Werkzeug ist nicht mehr erforderlich. An einem IDC-Kontakt sind in der gattungsgemäßen Schrift weitere Kontaktbereiche angeordnet.A generic terminal block is from the DE-A-37 108 96 known. Such terminal blocks and terminal devices allow the contacting of the conductors in the so-called IDC technique, in which cutting the terminal device sever the insulation of the conductor, whereupon contacting the Leiutungsadern takes place in a contacting area. A manual stripping of the conductor with a special tool is no longer necessary. At an IDC contact further contact areas are arranged in the generic document.

Eine weitere Reihenklemme mit IDC-Kontakten ist aus der DE 197 32 182 C1 bekannt.Another terminal block with IDC contacts is from the DE 197 32 182 C1 known.

Insbesondere im Bereich der Initiatoren-/Aktorenklemmen besteht der Bedarf nach einer Potentialverteilung über mehrere Klemmen hinweg (siehe z.B. die DE-A-19650989 ). Es ist daher die Aufgabe der Erfindung, eine Reihenklemme der gattungsgemäßen Art und die Anschlußvorrichtung der gattungsgemäßen Art derart weiterzubilden, daß auf problemlose und konstruktiv einfache Weise eine Potentialverteilung über mehrere Reihenklemmen hinweg realisiert wird.Especially in the area of the initiator / actuator terminals there is a need for a potential distribution over several terminals (see, for example, US Pat DE-A-19650989 ). It is therefore an object of the invention to provide a terminal of the generic type and the terminal device of the generic type such that a potential distribution over several terminal blocks is realized in a trouble-free and structurally simple manner.

Die Erfindung löst diese Aufgabe in Hinsicht auf die Reihenklemme durch den Gegenstand des Anspruchs 1.The invention solves this problem with regard to the terminal block by the subject of claim 1.

Ein besonderer Vorteil der Erfindung ist darin zu sehen, daß durch die Ausgestaltung der Schneidschiene an deren einem Ende der Schneidanschluß und an deren anderem Ende hiermit einstückig verbunden auf konstruktiv einfache Weise der Querverbinder ausgestaltet wird. Bevorzugt wird der Querverbinder kostengünstig und funktionssicher nach Art der EP 0 634 813 B1 ausgebildet.A particular advantage of the invention is the fact that the cross-connector is configured by the design of the cutting rail at one end of the cutting terminal and at the other end thereof integrally connected in a structurally simple manner. Preferably, the cross connector is inexpensive and reliable in the manner of EP 0 634 813 B1 educated.

Ganz besonders bevorzugt ist das Isolierstoffgehäuse im Bereich seiner Vorder- und Rückseite jeweils mit Aussparungen versehen, wobei aus der einen Aussparung die Steckerlasche aus dem Isolierstoffgehäuse vorsteht und wobei die auf der gegenüber liegenden Seite des Isolierstoffgehäuses liegende Aussparung zum Einstecken der Steckerlasche in den Buchsenkontakt ausgelegt ist. Ein separates Gehäuse für die Querverbinder, wie dies die EP 0 634 813 B1 vorschlägt, nach der die Querverbinder jeweils separate Gehäuse aufweisen und zunächst zu Leisten zusammengesteckt werden, welche dann als Einheit in die Klemmengehäuse eingesetzt werden, kann auf diese Weise entfallen.Most preferably, the insulating material is provided in the region of its front and back with recesses, wherein the plug tab protrudes from the Isolierstoffgehäuse from a recess and wherein the lying on the opposite side of the insulating housing recess for insertion of the connector tab is designed in the socket contact , A separate housing for the cross connectors, like this one EP 0 634 813 B1 suggests that after the cross-connector each have separate housing and are first put together to strips, which are then used as a unit in the terminal housing, can be omitted in this way.

Nach einer weiteren besonders bevorzugten Variante ist an das Isolierstoffgehäuse in Tragschienenrichtung bzw. senkrecht zur Haupterstreckungsebene der Reihenklemme ein Steckschutz für die Steckerlasche ausgebildet, der wirkungsvoll gegen Beschädigungen durch ein Fehlstecken des Betätigungswerkzeuges - typischerweise ein Schraubendreher - schützt.According to a further particularly preferred variant, a plug-in protection for the connector tab is formed on the insulating material in the rail direction or perpendicular to the main extension plane of the terminal block, which effectively protects against damage caused by incorrect insertion of the operating tool - typically a screwdriver.

Zweckmäßig wird die Schneidschiene mit weiteren in diese integrierten Funktionsbereichen versehen.The cutting rail is expediently provided with further functional areas integrated in it.

So ist nach einer Variante an das Verbindungsblech eine in sich gewinkelt ausgebildete Lasche angeformt, welche ein Auge aufweist. Alternativ/Optional kann an das Verbindungsblech ein Lötstift oder ein Buchsen- oder Steckerkontakt angeformt sein. Mit diesen Funktionsbereichen kann die Anschlußvorrichtung beispielsweise mit elektronischen Bauelementen oder aber mit Leiterplatten oder ähnlichen Einrichtungen verbunden/kombiniert werden.Thus, according to a variant of the connecting plate an integrally formed in angled tab formed, which has an eye. Alternatively / optionally, a soldering pin or a socket or plug contact can be molded onto the connecting plate. With these functional areas, the terminal device, for example, with electronic Components are connected or combined with printed circuit boards or similar devices.

Es bietet sich an, die gesamte Schneidschiene kostengünstig als einstückiges Stanz-/Biegeteil aus einem Metallband zu formen.It makes sense to cost-effectively form the entire cutting rail as a one-piece punched / bent part of a metal strip.

Weitere vorteilhafte Ausführungsformen sind den übrigen Unteransprüchen zu entnehmen.Further advantageous embodiments can be found in the remaining subclaims.

Fig. 1 zeigt eine Initiatoren-/Aktoren-Reihenklemme 2 - hier eine Initiatoren/Aktoren-Reihenklemme- mit einem hier einteiligen Isolierstoffgehäuse 4 aus Kunststoff, welches in seinem in Fig. 1 unteren Bereich Rastfüße 6, 8 zum Aufrasten der Reihenklemme auf eine Tragschiene T sowie in seinem oberen Bereich hier vier Anschlußvorrichtungen 10, 12 zum Kontaktieren elektrischer Leiter aufweist. Fig. 1 shows an initiator / actuators terminal 2 - here an initiators / Aktoren-Reihenklemme- with a one-piece insulating housing 4 made of plastic, which in its in Fig. 1 Lower portion locking feet 6, 8 for snapping the terminal on a mounting rail T and in its upper part here four connection devices 10, 12 for contacting electrical conductors.

Die beiden in Fig. 1 rechten Anschlußvorrichtungen 10 sind direkt über eine Stromschiene 14 leitend miteinander verbunden.The two in Fig. 1 right terminal devices 10 are connected directly via a busbar 14 conductive each other.

Die beiden in Fig. 1 linken Anschlußvorrichtungen 12 weisen dagegen Querverbinder 16 zur Kontaktieren der entsprechenden Anschlußvorrichtungen 12' benachbarter Reihenklemmen auf.The two in Fig. 1 On the other hand, left-hand connection devices 12 have transverse connectors 16 for contacting the corresponding connection devices 12 'of adjacent terminal blocks.

Die Anschlußvorrichtungen 10, 12 sind jeweils in sogenannter IDC- Technik ausgeführt.The connection devices 10, 12 are each implemented in so-called IDC technology.

Sie umfassen jeweils an den in Fig. 1 oberen, geschlitzt ausgebildeten Enden einer als Schneidschiene 40 ausgebildeten Stromschiene - siehe Fig. 4 - eine Kontaktfeder 18 mit einer sich mündungsartig erweiternden, ebenfalls geschlitzten Kontaktschneide 20 und einen relativ zur Kontaktschneide 20 längs des Schlitzes 22 der Schneidschiene 40 versetzten Kontaktierungsbereich 24 auf. Die beiden Schenkel 18a, b der Kontaktfeder 18 sind leicht winklig zueinander ausgerichtet (siehe Fig. 3)They each include the in Fig. 1 upper, slotted ends formed as a cutting rail 40 busbar - see Fig. 4 - A contact spring 18 with a muzzle-like widening, also slotted contact blade 20 and a relative to the contact blade 20 along the slot 22 of the cutting rail 40 offset contacting region 24. The two legs 18a, b of the contact spring 18 are slightly angled to each other (see Fig. 3 )

Wird ein Leiter in die an ihren Enden geschlitzt ausgebildete Stromschiene 14 eingeführt, wird zunächst von den Kontaktschneiden 20 die Isolierung des Leiters durchtrennt und beim weiteren Einschieben des Leiters etwas aufgeweitet. Dann werden die Kontaktierungsbereiche 24 der Kontaktfeder gegen die Leitungsadem des Leiters (nicht dargestellt) gedrückt.If a conductor is inserted into the busbar 14 formed slotted at its ends, the insulation of the conductor is first severed by the contact blades 20 and widened somewhat as the conductor is pushed further. Then, the contacting portions 24 of the contact spring are pressed against the line electrode of the conductor (not shown).

Die Kontaktfedern 18 werden im Kontaktierungsbereich 24 von einer im Querschnitt im wesentlichen U-förmig ausgebildeten Kraftfeder 26 eingefaßt.The contact springs 18 are bordered in the contacting region 24 by a cross-sectionally substantially U-shaped force spring 26.

Die Kraftfeder 26 weist entsprechend der Lehre der DE 197 32 182 C1 im wesentlichen flächig ausgebildete Federschenkel 28 auf, wobei die im wesentlichen flächigen Federschenkel 28 im wesentlichen senkrecht zu der Kontaktschneide 20 und dem Kontaktierungsbereich 24 verlaufen und diese entlang des Kontaktierungsbereiches 24 umgreifen. Seitliche Aussparungen 29 in den Federschenkeln 28 erlauben einen seitlichen Durchtritt der Leiterisolierung des zu kontaktierenden Leiters, was entscheidend zu einer relativ zum Leiterdurchmesser schmalen Bauform der Reihenklemme beiträgtThe force spring 26 has according to the teaching of DE 197 32 182 C1 substantially flat spring leg 28, wherein the substantially flat spring legs 28 extend substantially perpendicular to the contact blade 20 and the contacting region 24 and embrace them along the contacting region 24. Lateral recesses 29 in the spring legs 28 allow a lateral passage of the conductor insulation of the conductor to be contacted, which contributes decisively to a narrow relative to the conductor diameter design of the terminal block

Das Be- und Endschalten der Anschlußvorrichtungen 10, 12 erfolgt jeweils mit Hilfe eines im Isolierstoffgehäuse mit Zapfen 31 in Nuten/Schlitzen 33 verschieblich geführten Kontaktbetätigungsstückes 30. Die Kontaktbetätigungsstücke 30 sind jeweils bei der Erstmontage von oben her in Öffnungen 32 des vorzugsweise einstückig ausgebildeten Isolierstoffgehäuses 4 eingesetzt und dort im wesentlichen parallel zu den Kontaktfedern 18 verschieblich geführt.The loading and final switching of the connecting devices 10, 12 is carried out in each case by means of a in the insulating housing with pin 31 in grooves / slots 33 slidably guided Kontaktbetätigungsstückes 30. The Kontaktbetätigungsstücke 30 are each used in the initial assembly from above into openings 32 of the preferably integrally formed insulating housing 4 and there guided substantially parallel to the contact springs 18 slidably.

Zunächst wird ein Leiter (in Fig. 1 nicht dargestellt) in die Öffnung 34 des Kontaktbetätigungsstückes 30 eingeführt. Es ist möglich, auf der von dem Kontaktierungsbereich 24 abgewandten Seite der Kontaktbetätigungsstücke 30 in die Öffnungen 32 des Isolierstoffgehäuses 4 zwischen das Isolierstoffgehäuse 4 und das Kontaktbetätigungsstück 30 ein Betätigungswerkzeug in das Isolierstoffgehäuse 4 einzuführen und mit diesem das Kontaktbetätigungsstück 30 im Klemmengehäuse 2 zu verschieben.First, a leader (in Fig. 1 not shown) inserted into the opening 34 of the Kontaktbetätigungsstückes 30. It is possible to introduce an actuating tool into the insulating housing 4 on the side of the contact actuating pieces 30 facing away from the contacting area 24 into the openings 32 of the insulating housing 4 between the insulating housing 4 and the contact actuating piece 30 and to displace the contact actuating piece 30 in the terminal housing 2 therewith.

Bei der Bewegung des Betätigungswerkzeuges wird von den Kontaktschneiden 20 die Leiterisolierung durchtrennt und beim weiteren Einschieben des Leiters in den Schlitz 22 aufgeweitet, bis die Leitungsader(n) des Leiters die Kontaktierungsbereiche 24 der Anschlußvorrichtungen 10, 12 kontaktieren.During the movement of the actuating tool, the conductor insulation is severed by the contact blades 20 and widened during further insertion of the conductor into the slot 22 until the conductor wire (s) of the conductor contact the contacting regions 24 of the connection devices 10, 12.

Beim Entschalten wird das Betätigungswerkzeug an der relativ zur Tragschiene bzw. Klemmenmitte außen liegenden Seite des Kontaktbetätigungsstückes 30 in die Öffnung 32 des Isolierstoffgehäuses 4 eingeführt. Daraufhin wird das Kontaktbetätigungsstück 30 mit dem Betätigungswerkzeug in entgegengesetzter Richtung verschoben. Dabei zieht das Kontaktbetätigungsstück 30 den Leiter aus dem Kontaktierungsbereich 24 der Kontaktfeder 18 bis er schließlich an der Kontaktschneide 20 vorbei aus der Kontaktfeder 18 gleitet, wonach der Leiter nach oben hin aus dem Kontaktbetätigungsstück 30 herausgezogen werden kann.When switching off the operating tool is introduced at the relative to the support rail or terminal center outside of the side of the Kontaktbetätigungsstückes 30 in the opening 32 of the insulating housing 4. Then, the contact operation piece 30 is displaced with the operating tool in the opposite direction. In this case, the contact actuating piece 30 pulls the conductor from the contacting region 24 of the contact spring 18 until it finally slides past the contact blade 20 from the contact spring 18, after which the conductor can be pulled out of the contact actuating piece 30 at the top.

Die Kraftfeder 26 ist an ihrer zur Kontaktschneide 20 hin weisenden Seite im Bereich der relativ zur Tragschiene unteren Ecke mit einem Vorsprung 36 versehen, welcher ein Widerlager 38 im Isolierstoffgehäuse untergreift.The force spring 26 is provided on its side facing the contact blade 20 side in the region of the lower rail relative to the support rail with a projection 36 which engages under an abutment 38 in the insulating housing.

Nach Fig. 1 und 4 bildet die Kontaktfeder 18 das eine Ende der Schneidschiene 40. Die Schneidschiene 40 weist in der Seitenansicht der Fig. 1 eine Art U-Form auf, wobei an dem einen Längsschenkel des U die Kontaktfeder 18 und an dem anderen Ende des U ein Querverbinder 16 in Form eines Steckkontaktelementes 42 ausgebildet ist. Das Steckkontaktelement 42 an sich ist nach Art des Steckkontaktelementes des europäischen Patentes EP 0 634 813 B1 ausgebildet und einstückig an das von der Kontaktfeder 18 abgewandten Ende der Schneidschiene 40 angeformt.To Fig. 1 and 4 forms the contact spring 18, the one end of the cutting rail 40. The cutting rail 40 has in the side view of Fig. 1 a kind of U-shape, wherein on one longitudinal leg of the U, the contact spring 18 and at the other end of the U is a cross-connector 16 in the form of a plug-in contact element 42 is formed. The plug contact element 42 per se is the nature of the plug contact element of the European patent EP 0 634 813 B1 formed and integrally formed on the side facing away from the contact spring 18 end of the cutting rail 40.

Das Steckkontaktelement 42 umfaßt eine Steckerlasche 44 und einen Buchsenkontakt 46, welche rechtwinklig zur Haupterstreckungsebene der Reihenklemme bzw. parallel zur Tragschienenrichtung ausgerichtet sind.The plug contact element 42 comprises a plug tab 44 and a socket contact 46, which are aligned at right angles to the main extension plane of the terminal block or parallel to the mounting rail direction.

Die Steckerlasche 44 ist zum Eingriff in den Buchsenkontakt 44 der nächsten anzureihenden Reihenklemme auf der Tragschiene T ausgebildet, so daß sich in Tragschienenrichtung eine sich über mehrere Reihenklemmen hinweg erstreckende Querverbindung ausbildet.The connector tab 44 is formed for engagement in the socket contact 44 of the next row to be adorned on the mounting rail T, so that forms in the rail direction, over a plurality of terminal blocks away extending cross-connection.
