Description

Die Erfindung betrifft einen elektr. Verbinder mit einem Isolierstoffgehäuse, das an zwei einander gegenüberliegenden Gehäuseseiten Einstecköffnungen aufweist, und zwar auf der einen Seite für das Einführen eines elektr.Kontaktstiftes und auf der anderen Seite für das Einstecken des isolationsfreien Endes mindestens eines elektr.Leiters. Auf der Stift-Seite besitzt der Verbinder einen Stift-Klemmkontakt, so daß der Verbinder auf den Kontaktstift einer Leiterplatte oder auf den Anschluß-Kontaktstift eines sonstigen Gegenkontaktes aufsteckbar ist, und auf der Leiter-Seite besitzt der Verbinder für jeden anzuschließenden elektr.Leiter einen Blattfeder-Klemmanschluß mit einer Blattfeder, die sich in Leitereinsteckrichtung und schräg gegen den elektr. Leiter erstreckt und mit ihrem Blattfeder ende das isolationsfreie Ende des eingesteckten elektr.Leiters festklemmt.The invention relates to an electr. Connector with an insulating housing having on two opposite sides housing insertion, on the one hand for the insertion of an electr. Contact pin and on the other side for the insertion of the insulation-free end of at least one elektr.Leiters. On the pin side of the connector has a pin terminal contact, so that the connector can be plugged onto the contact pin of a printed circuit board or on the terminal contact pin of another mating contact, and on the conductor side, the connector has for each electrical conductor to be connected a leaf spring clamp connection with a leaf spring which is in Leitereinsteckrichtung and obliquely against the electr. Ladder extends and with its leaf spring end clamps the insulation-free end of the inserted elektr.Leiters.

Elektr.Verbinder dieses Typs sind bereits 1976 in der GB 1 528 993 beschrieben. Sie sind dort als zweipolige Verbinder vorgestellt, bestehend aus zwei einpoligen Verbindern, die in einem gemeinsamen Blockgehäuse aus Isolierstoff angeordnet sind, so daß der zweipolige Blockgehäuse-Verbinder mit Bezug auf zwei parallel positionierte Kontaktstifte als "plug and socket arrangement" verstanden werden kann. Gemäß der GB 1 528 993 sind für das Aufstecken des Verbinders auf die Kontaktstifte Buchsen-Klemmkontakte vorgesehen, die derart auszuführen sind, daß der Verbinder im Bedarfsfall wieder von den Kontaktstiften abgezogen werden kann. Ebenso ist vorgesehen, daß auch die auf der anderen Seite des Verbinders vorhandenen Blattfeder-Klemmanschlüsse für die elektr.Leiter im Bedarfsfall wieder geöffnet werden können, indem die Blattfedern der Blattfeder-Klemmanschlüsse mittels eines Werkzeuges zurückgedrückt werden, so daß die elektr.Leiter aus dem Verbinder wieder herausgezogen werden können.Elektr.Verbinder this type are already in 1976 in the GB 1 528 993 described. They are presented there as a two-pole connector, consisting of two single-pole connectors, which are arranged in a common block housing made of insulating material, so that the two-pole block housing connector with respect to two pins positioned in parallel can be understood as a "plug and socket arrangement". According to the GB 1 528 993 are provided for attaching the connector to the contact pins jack terminal contacts, which are designed such that the connector can be withdrawn, if necessary, again from the contact pins. It is also envisaged that the present on the other side of the connector leaf spring terminals for the electrical ladder can be reopened if necessary by the leaf springs of the leaf spring clamped connections are pushed back by means of a tool, so that the electrical conductor from the Connector can be pulled out again.

Ein weiterer Verbinder dieses Typs ist aus der EP 0 735 616 A2 bekannt (siehe dort Figuren 18 und 19). Er ist als "elektrischer Steckverbinder" bezeichnet, der auf die eingelöteten Kontaktstifte einer Leiterplatte aufsteckbar ist und infolge eines tulpenförmig auffedernden Buchsen-Klemmkontaktes auch wieder von den Kontaktstiften abziehbar ist. Auf der anderen Seite des Verbinders ist wiederum ein Blattfeder-Klemmanschluß für den elektr.Leiter vorhanden, der ebenfalls (wie bei der GB 1 528 993 ) als lösbarer Blattfeder-Klemmanschluß ausgeführt ist.Another connector of this type is from the EP 0 735 616 A2 known (see figures 18 and 19). He is as "Electrical connector" referred to, which is attachable to the soldered pins of a printed circuit board and as a result of a tulip spring auffedernden female terminal contact is again removable from the pins. On the other side of the connector in turn a leaf spring clamp connection for the electrical conductor is present, which also (as in the GB 1 528 993 ) is designed as a detachable leaf spring clamp connection.

Beide vorgenannten Verbinder gehen davon aus, daß ihre Stift-Klemmkontakte und ihre Leiter-Klemmanschlüsse in ihrer Gesamtheit aus einem Stück Federstahlblech gefertigt sind, wobei das Stück Federstahlblech auf der Stift-Seite zu einem Buchsen-Klemmkontakt verformt ist und auf der Leiter-Seite einen integrierten Blattfeder-Klemmanschluß für den elektr.Leiter bildet. Zwischen beiden Seiten übernimmt das Stück Federstahlblech die Stromleitungsfunktion, so daß bei der Materialauswahl auch auf eine brauchbare Stromleitfähigkeit des Federstahlbleches geachtet werden muß, was sich in den Materialkosten des Federstahlbleches niederschlägt.Both of the aforementioned connectors assume that their pin terminal contacts and their conductor terminal connections are made in their entirety from a piece of spring steel sheet, wherein the piece of spring steel sheet is deformed on the pin side to a female terminal contact and on the conductor side a integrated leaf spring clamp connection for the electrical conductor forms. Between both sides of the piece spring steel sheet takes over the power line function, so that care must be taken in the selection of materials on a useful Stromleitfähigkeit the spring steel, which is reflected in the cost of the spring steel sheet.

Hinsichtlich ihrer konstruktiven Bauform sind die beiden vorgenannten Verbinder in der Weise ausgeführt, daß der Stift-Klemmkontakt einerseits und der Leiter-Klemmanschluß andererseits ausreichend voneinander entfernt angeordnet sind, so daß sich beide Seiten nicht gegenseitig behindern können. Die Isolierstoffgehäuse dieser bekannten Verbinder sind entsprechend groß bemessen.With regard to their structural design, the two aforementioned connectors are designed in such a way that the pin terminal contact on the one hand and the conductor terminal connection on the other hand are sufficiently remote from each other, so that both sides can not interfere with each other. The insulating material housing this known connector are sized accordingly large.

Aufgabe der Erfindung ist es, einen Verbinder der vorgenannten Art zu schaffen, der kostengünstiger herzustellen ist und dessen Baugröße zudem erheblich reduziert werden kann, so daß er auch unter beengten Platzverhältnissen sowohl als einpoliger als auch als mehrpoliger Verbinder eingesetzt werden kann.The object of the invention is to provide a connector of the aforementioned type, which is inexpensive to manufacture and its size can also be significantly reduced, so that it can be used in a confined space both as unipolar and as a multipole connector.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Isolierstoffgehäuse des Verbinders für jeden anzuschließenden elektr.Leiter einen Anschlußraum zur Verfügung stellt, in den der Kontaktstift und der elektr.Leiter nebeneinander mit in etwa paralleler Ausrichtung einsteckbar sind derart, daß sich der Kontaktstift und der elektr.Leiter mit ihren axialen Längen überlappen. Dabei ist der Kontaktstift in dem Anschlußraum lage-fixiert gehalten, wohingegen der elektr.Leiter in einem konstruktiv zugelassenen Verschiebebereich quer zu seiner Leiterachse verschiebbar ist (vorzugsweise parallel verschiebbar ist), wobei das Blattfederende des Blattfeder-Klemmanschlusses an derjenigen Seite des elektr.Leiters anliegt, die dem Kontaktstift gegenüberliegt, so daß die Klemmkraft der Blattfeder den elektr.Leiter in Richtung des Kontaktstiftes drückt.This object is achieved in that the insulating material of the connector for each electrical conductor to be connected provides a terminal space available, in which the contact pin and the electrical conductor side by side with approximately parallel orientation can be inserted such that the contact pin and the electr .Lap overlap with their axial lengths. In this case, the contact pin is held fixed in position in the terminal space, whereas the electrical conductor is displaceable transversely to its conductor axis in a structurally permissible displacement region (preferably being displaceable in parallel), the leaf spring end of the leaf spring clamping connection abutting that side of the electrical conductor , which is opposite to the contact pin, so that the clamping force of the leaf spring presses the electrical conductor in the direction of the contact pin.

Es gibt zwei grundsätzliche Ausführungsformen des erfindungsgemäßen Verbinders.There are two basic embodiments of the connector according to the invention.

Bei der ersten Ausführungsform kontaktiert der elektr.Leiter den Kontaktstift direkt (siehe Anspruch 2), so daß diese Ausführungsform zu Stromleitungszwecken zwischen dem elektr. Leiter und dem Kontaktstift kein zusätzliches stromleitendes Material benötigt. Das ist kosten- und materialsparend. Diese Ausführungsform des Verbinders wird bevorzugt für eindrähtige massive elektr.Leiter verwendet, da diese ohne vorheriges Öffnen des Blattfeder-Klemmanschlusses in den Anschlußraum des Verbinders einsteckbar sind.In the first embodiment, the electrical conductor contacted the contact pin directly (see claim 2), so that this embodiment for power line purposes between the electr. Conductor and the contact pin no additional current-conducting material needed. That is cost and material saving. This embodiment of the connector is preferably used for solid solid electrical conductors, since they can be inserted into the terminal space of the connector without prior opening of the leaf spring clamping connection.

Die zweite Ausführungsform des neuen Verbinders wird bevorzugt für mehrdrähtige flexible elektr.Leiter empfohlen, bei denen in der üblichen Weise der Blattfeder-Klemmanschluß geöffnet werden kann, bevor der flexible Leiter in den Anschlußraum des Verbinders eingeführt wird. Diese Ausführungsform des Verbinders hat das besondere Merkmal (siehe Anspruch 3), daß zwischen dem elektr. Leiter und dem Kontaktstift im Bereich ihrer gegenseitigen axialen Überlappung eine Kontaktwand positioniert ist, die den elektr.Leiter beim Einsteckvorgang in den Anschlußraum in Richtung seiner Leiterachse führt, und zwar vorzugsweise bis in eine bodenseitige, zur Kontaktwand hin offene Leiter-Fangtasche. Durch diese Kontaktwand-Führung ist das unerwünschte Abspleißen einzelner Drähte eines mehrdrähtigen flexiblen Leiters vermieden. Die Kontaktwand ist in einem konstruktiv zugelassenen Verschiebebereich quer zur Leiterachse des elektr.Leiters und gemeinsam mit dem elektr.Leiter in Richtung des Kontaktstiftes verschiebbar, so daß der elektr.Leiter direkt die Kontaktwand und die Kontaktwand direkt den Kontaktstift kontaktiert.The second embodiment of the new connector is preferably recommended for multi-wire flexible electrical conductors, where in the usual way the leaf spring clamp connection can be opened before the flexible conductor is inserted into the terminal space of the connector. This embodiment of the connector has the special feature (see claim 3) that between the electr. Head and the contact pin in the region of their mutual axial overlap a contact wall is positioned, which leads the electrical conductor during insertion into the terminal compartment in the direction of its conductor axis, preferably to a bottom side, the contact wall towards open conductor catch bag. Through this contact wall guide the unwanted splicing of individual wires of a stranded flexible conductor is avoided. The contact wall is in a structurally approved displacement range transverse to the conductor axis of the elektr.Leiters and together with the elektr.Leiter in the direction of the contact pin displaceable, so that the electrical conductor directly contacted the contact wall and the contact wall directly to the contact pin.

Ein Verbinder mit den vorstehenden Merkmalen ist äußerst kostengünstig herzustellen. Bei dem neuen Verbinder wird nur noch ein kleines Stück Federstahlblech verwendet und zwar ausschließlich zur Bildung des Blattfeder-Klemmanschlusses. Der hierfür erforderliche Materialeinsatz kann insbesondere dann erheblich reduziert werden, wenn sich die Blattfeder des Blattfeder-Klemmanschlusses am Isolierstoffgehäuse des Verbinders abstützt. Anspruch 8 schlägt diesbezüglich vor, daß der Blattfeder-Klemmanschluß eine U-förmig gebogene zweischenkelige Blattfeder besitzt, die einen Blattfeder-Klemmschenkel und einen Blattfeder-Halteschenkel aufweist, wobei der Blattfeder-Halteschenkel in dem Isolierstoffgehäuse des Verbinders durch Verrastung mit dem Isolierstoffgehäuse festgelegt ist.A connector having the above features is extremely inexpensive to manufacture. In the new connector only a small piece of spring steel sheet is used and only to form the leaf spring clamp connection. The material required for this purpose can be significantly reduced, in particular, when the leaf spring of the leaf spring clamp connection is supported on the insulating housing of the connector. Claim 8 proposes in this regard that the leaf spring clamp connection has a U-shaped bent two-legged leaf spring, which has a leaf spring clamping leg and a leaf spring holding leg, wherein the leaf spring holding leg is fixed in the insulating housing of the connector by latching with the insulating material.

Hinsichtlich der geforderten Reduzierung der Baugröße des Verbinders gehört es zur Lehre der Erfindung, daß sich die in den Verbinder einzusteckenden axialen Längen des Kontaktstiftes und des elektr.Leiters überlappen. Diese Überlappung kann maximal sein, indem der elektr.Leiter bis zu einer bodenseitigen Abschlußwand in den Anschlußraum des Verbinders eingesteckt wird, so daß das Ende des elektr.Leiters bis nahe an den Fußpunkt des elektr.With regard to the required reduction in the size of the connector, it is part of the teaching of the invention that the axial lengths of the contact pin and the electrical conductor to be inserted into the connector overlap. This overlap can be maximum by the electrical conductor is inserted to a bottom-side end wall in the terminal compartment of the connector, so that the end of the elektr.Leiters close to the base of the electr.

Kontaktstiftes oder eines sonstigen Anschlußstiftes herangeführt ist. Durch diese maximale Überlappung wird erreicht, daß die Bauhöhe des Verbinders nicht wesentlich größer ist als die Einstecktiefe des elektr.Leiters.Contact pin or another pin is introduced. This maximum overlap ensures that the overall height of the connector is not substantially greater than the insertion depth of the elektr.Leiters.

Die neuen Verbinder können pro Pol einen oder zwei Anschlußräume für elektr.Leiter aufweisen, wobei gemäß Anspruch 4 für einen Verbinder mit zwei Anschlußräumen nur ein Kontaktstift ausreichend ist, wenn dieser mittig zwischen den Anschlußräumen positioniert ist und beiden Anschlußräumen als Kontaktstift dient.The new connector can have one or two connection spaces for electrical conductor per pole, wherein according to claim 4 for a connector with two terminal spaces only one contact pin is sufficient if this is positioned centrally between the terminal spaces and serves both terminal spaces as a contact pin.

Die erfindungsgemäßen Verbinder können prinzipiell auf jeden in der Praxis gebräuchlichen Kontaktstift und/oder Anschlußstift aufgesteckt werden. Anspruch 5 der vorliegenden Erfindung empfiehlt, das Kopfende des jeweiligen Kontaktstiftes in dem Anschlußraum durch einen Isolierstoff-Übergriff positionsgenau zu fixieren. Diese Positionsgenauigkeit des jeweils verwendeten Kontaktstiftes verbessert die Kontaktanlage des elektr.Leiters an dem Kontaktstift.In principle, the connectors according to the invention can be plugged onto any contact pin and / or connecting pin commonly used in practice. Claim 5 of the present invention recommends to fix the head end of the respective contact pin in the terminal compartment by an insulating material grip positionally accurate. This positional accuracy of the contact pin used in each case improves the contact of the elektr.Leiters on the contact pin.

Dem gleichen Zweck der Positionsgenauigkeit des Kontaktstiftes dient der Anspruch 6, wonach das Fußende des Kontaktstiftes mittels eines seitlichen Stützlagers gegen das Isolierstoffgehäuse des Verbinders lage-fixiert gehalten ist.The same purpose of the positional accuracy of the contact pin is the claim 6, according to which the foot end of the contact pin is held fixed in position by means of a lateral support bearing against the insulating material of the connector.

Die in dem Isolierstoffgehäuse des Verbinders positionsgenau und lage-fixiert gehaltenen Kontaktstifte können auf Wunsch der weiterverarbeitenden Industrie bereits von dem Herstellerbetrieb der neuen Verbinder in die jeweiligen Anschlußräume des Verbinders eingesteckt werden, so daß dann die weiterverarbeitende Industrie die Verbinder mit den fußseitig vorstehenden Kontaktstiften direkt z.B. in die Einlötöffnungen einer Leiterplatte einsetzen kann und verlöten kann.The positionally accurate and positionally fixed in the insulating housing of the connector pins can be inserted at the request of the processing industry already from the manufacturer's operation of the new connector in the respective terminal spaces of the connector, so that then the processing industry, the connector with the foot-side projecting pins directly. can use in the solder holes of a circuit board and can solder.

Es ist ein Vorteil, Kontaktstifte zu verwenden, die unterhalb ihres Kopfendes mit einer Vorwölbung ausgebildet sind, deren Scheitellinie sich quer zur Längsachse des Kontaktstiftes erstreckt (siehe Anspruch 7). In Verbindung mit einer in Richtung der Längsachse des Kontaktstiftes verlaufenden Kontaktlinie eines elektr.Leiters ergibt sich dann im Kreuzungspunkt der genannten Linien ein punktförmiger Anlagekontakt mit einer höheren spezifischen Flächenpressung, wodurch der Stromübergang in diesem Kontaktpunkt verbessert ist.It is an advantage to use contact pins which are formed below their head end with a protrusion whose apex line extends transversely to the longitudinal axis of the contact pin (see claim 7). In conjunction with an extending in the direction of the longitudinal axis of the contact pin contact line of a elektr.Leiters then results in the intersection of the lines mentioned a punctiform contact contact with a higher specific surface pressure, whereby the current transition is improved in this contact point.

Fig. 1 zeigt einen Querschnitt durch einen Verbinder gemäß der Erfindung und zwar im aufgesteckten Zustand auf einen Kontaktstift 3, der in die Leiterplatte 4 eingelötet ist. Der Kontaktstift 3 besitzt die Vorwölbung 5 und ist mittels des Isolierstoff-Übergriffs 6 positionsgenau in dem Anschlußraum 7 des Isolierstoffgehäuses 8 gehalten.Fig. 1 shows a cross section through a connector according to the invention in the plugged state on a contact pin 3, which is soldered into the circuit board 4. The contact pin 3 has the protrusion 5 and is held by means of the insulating material grip 6 positionally accurate in the terminal compartment 7 of the insulating housing 8.

Der elektr.Leiter 9 wird von der oberen Seite in den Verbinder eingesteckt. In dem Anschlußraum 7 des Verbinders sind der Kontaktstift 3 und der elektr. Leiter 9 nebeneinander angeordnet und überlappen sich mit ihren axialen Längen. Mittels der Vorwölbung 5 kontaktiert der Kontaktstift den elekt.Leiter 9 direkt, so daß ein unmittelbarer Stromübergang zwischen dem Kontaktstift und dem elektr. Leiter stattfindet.The electrical conductor 9 is inserted from the upper side into the connector. In the terminal compartment 7 of the connector of the contact pin 3 and the electr. Head 9 arranged side by side and overlap with their axial lengths. By means of the protrusion 5 of the contact pin contacts the elekt.Leiter 9 directly, so that a direct current transfer between the contact pin and the electr. Head takes place.

Der elektr.Leiter 9 ist (wie die Gehäusedarstellung in Fig. 1 zeigt) mittels der Federkraft (Klemmkraft) der Blattfeder 11 nach links gegen den Kontaktstift 3 verschiebbar. Die Verschiebung erfolgt innerhalb des konstruktiv zugelassenen Verschiebebereichs 10. Das gewährleistet, daß der elektr.Leiter stets kontaktsicher an dem jeweils verwendeten Kontaktstift anliegt.The electrical conductor 9 is (as the housing representation in Fig. 1 shows) by means of the spring force (clamping force) of the leaf spring 11 to the left against the contact pin 3 slidably. The shift takes place within the structurally approved displacement range 10. This ensures that the electrical conductor always bears against contact with the contact pin used in each case.

Die in den Verbinder eingebaute Blattfeder ist U-förmig aus einem Stück Federstahlblech gefertigt und besitzt einen Blattfeder-Klemmschenkel 11 und einen Blattfeder-Halteschenkel 12. Sie ist mit ihrem Kopfbogen 13 und ihrem Halteschenkel 12 in dem Isolierstoffgehäuse lage-fixiert gehalten.The built-in connector leaf spring is U-shaped made of a piece of spring steel sheet and has a leaf spring clamping leg 11 and a leaf spring holding leg 12. It is kept fixed in position with its head bow 13 and its retaining legs 12 in the insulating.

In dem Isolierstoffgehäuse des Verbinders ist in der üblichen Weise eine Prüföffnung 14 vorgesehen. Auch ist es möglich, das Isolierstoffgehäuse mit einem Drücker aus Isolierstoff auszurüsten, der manuell zu betätigen ist, um im Bedarfsfall den Blattfeder-Klemmschenkel 11 von dem elektr.Leiter 9 abzudrücken, so daß die Klemmung des elektr.Leiters gelöst ist und der elektr.Leiter aus dem Verbinder herausgezogen werden kann. Das gleiche Ergebnis wird üblicherweise auch mit einer Betätigungsöffnung im Isolierstoffgehäuse erreicht, durch die ein Werkzeug (z.B. eine Schraubendreherklinge) bis an den Blattfeder-Klemmschenkel 11 herangeführt werden kann, wie dies z.B. auch in der Fig. 3 dargestellt ist.In the insulating housing of the connector, a test opening 14 is provided in the usual way. It is also possible to equip the insulating material with a pusher of insulating material, which is to be operated manually, if necessary, to squeeze the leaf spring clamping leg 11 of the electrical conductor 9, so that the clamping of the electrical conductor is released and the electr. Ladder can be pulled out of the connector. The same result is usually achieved also with an actuating opening in the insulating housing, through which a tool (for example a screwdriver blade) can be brought up to the leaf-spring clamping limb 11, as e.g. Also shown in FIG. 3.

Fig. 2 zeigt in perspektivischer Darstellung einen mehrpoligen Verbinder der erfindungsgemäßen Art mit einem aus Isolierstoff gefertigten Blockgehäuse 15. Die in das Blockgehäuse insgesamt eingebauten fünf einpoligen Verbinder sind baugleich und entsprechen jeweils dem Ausführungsbeispiel gemäß Fig. 1. Sie sind zueinander wechselseitig ausgerichtet. Dieses Anordnungsschema ist platzsparend, es kann aber auch durch jedes andere gewünschte Anordnungsschema ersetzt werden.Fig. 2 shows a perspective view of a multipolar connector of according to the invention with a manufactured from insulating block housing 15. The built in the block housing five five-pin connector are identical and each correspond to the embodiment of FIG. 1. They are mutually aligned. This layout scheme saves space, but it can also be replaced by any other desired layout scheme.

Fig. 3 zeigt den perspektivischen Querschnitt eines einpoligen Verbinders gemäß der Erfindung mit einem Anschlußraum 16, der für den Anschluß eines mehrdrähtigen flexiblen Leiters 17 besondere Merkmale aufweist. Der Anschlußraum schließt an seiner linken Seite mit einer Kontaktwand 18 ab, die zwischen dem flexiblen Leiter 17 und dem Kontaktstift 19 positioniert ist und die in einen konstruktiv zugelassenen Verschiebebereich 20 quer zur Leiterachse des elektr.Leiters 17 und gemeinsam mit diesem in Richtung des Kontaktstiftes 19 verschiebbar ist, um einen guten elektr. Kontakt zwischen dem Kontaktstift, der Kontaktwand und dem flexiblen Leiter sicherzustellen. Die Kontaktwand 18 führt den flexiblen Leiter beim Einsteckvorgang bis in eine bodenseitige, zur Kontaktwand hin offene Leiter-Fangtasche 21, wodurch verhindert wird, daß beim Einsteckvorgang Einzeldrähte von dem mehrdrähtigen flexiblen Leiter 17 abspleißen. Die Leiterklemmstelle zwischen der Blattfeder 22 und der Kontaktwand 18 kann zum Anschließen und Lösen des elektr.Leiters geöffnet werden, indem eine Schraubendreherklinge über die Betätigungsöffnung 23 in den Anschlußraum eingeführt wird und mittels der Schraubendreherklinge die Blattfeder vom elektr.Leiter wegbewegt wird. Bei 24 ist die übliche Prüföffnung vorgesehen.Fig. 3 shows the perspective cross section of a single-pole connector according to the invention with a terminal compartment 16 which has 17 special features for the connection of a multi-wire flexible conductor. The terminal compartment terminates at its left side with a contact wall 18 which is positioned between the flexible conductor 17 and the contact pin 19 and in a structurally approved displacement area 20 transversely to the conductor axis of the electr.Leiters 17 and together with this in the direction of the contact pin 19th is movable to a good electr. Ensure contact between the contact pin, the contact wall and the flexible conductor. The contact wall 18 leads the flexible conductor in the insertion process into a bottom-side, to the contact wall open conductor-catching pocket 21, thereby preventing splicing off individual wires from the stranded flexible conductor 17 during the insertion process. The conductor terminal point between the leaf spring 22 and the contact wall 18 can be used to connect and disconnect the elektr.Leiters be opened by a screwdriver blade is inserted via the actuating opening 23 in the terminal compartment and by means of the screwdriver blade, the leaf spring is moved away from the electrical conductor. At 24 the usual test opening is provided.

Fig. 4 zeigt einen Verbinder, der mit dem Verbinder gemäß Fig. 1 vergleichbar ist, bei dem jedoch der in den Anschlußraum eingesteckte Kontaktstift 25 ein unteres Stützlager 26 aufweist, das gegen das Isolierstoffgehäuse des Verbinders gerichtet ist und die Positionsgenauigkeit des Kontaktstiftes in dem Anschlußraum verbessert.Fig. 4 shows a connector which is comparable to the connector of Fig. 1, but in which the plug pin 25 inserted in the terminal space has a lower support bearing 26 directed against the insulator housing of the connector and the positional accuracy of the contact pin in the terminal space improved.

Fig. 5 zeigt im Querschnitt einen einpoligen Verbinder gemäß der Erfindung, der zwei Anschlußräume für zwei elektr. Leiter 27 und 28 besitzt und zur Herstellung einer elektr.Verbindung auf nur einen Kontaktstift 29 aufsteckbar ist. Der Kontaktstift 29 ist zu seiner Längsachse spiegelsymmetrisch ausgebildet und dient somit beiden Anschlußräumen als Kontaktstift. Er besitzt beidseitig jeweils ein Stützlager 30, die das positionsgenaue Aufstecken des Verbinders auf den Kontaktstift gewährleisten.Fig. 5 shows in cross section a single-pole connector according to the invention, the two terminal compartments for two electr. Head 27 and 28 has and can be plugged for the preparation of a elektr.Verbindung on only one contact pin 29. The contact pin 29 is mirror-symmetrical to its longitudinal axis and thus serves both terminal spaces as a contact pin. He has on both sides in each case a support bearing 30, which ensure the positionally accurate plugging the connector on the contact pin.

Im Regelfall werden die Verbinder auf den Kontaktstift einer Leiterplatte oder auf den Anschluß-Kontaktstift eines sonstigen Gegenkontaktes (z.B. an einem elektr. Gerät) aufgesteckt. Das kann wahlweise vor oder nach dem Anschließen der elektr.As a rule, the connectors are plugged onto the contact pin of a printed circuit board or onto the contact pin of another counter contact (eg on an electrical device). This can optionally before or after connecting the electr.

Leiter an den Verbinder erfolgen. Im Bedarfsfall, z.B. bei einem Defekt eines mit dem Verbinder verdrahteten Bauteils, ist es arbeitstechnisch von Vorteil, den Verbinder von den Kontaktstiften abzuziehen und die komplette Bauteilgruppe (z.B. bestehend aus dem defekten Bauteil und dem mit dem Bauteil verdrahteten Verbinder) gegen eine neue Bauteilgruppe auszutauschen.Conductor to the connector. If necessary, e.g. In the event of a defect of a component wired to the connector, it is industrially advantageous to strip the connector from the contact pins and replace the complete group of components (e.g., the defective component and the connector wired to the component) with a new group of components.

In der Praxis gibt es auch Anwendungsfällen für den neuen Verbinder, bei denen verlangt wird, daß der Verbinder nicht von den Kontaktstiften abgezogen werden darf, d.h. es soll für den Kontaktstift eine Auszugssperre vorhanden sein, so daß dieser nicht aus dem Anschlußraum des Verbinders herausgezogen werden kann. Dies ist in den Figuren 6 bis 8 dargestellt.In practice, there are also applications for the new connector in which it is required that the connector must not be pulled off the contact pins, i. it should be present for the contact pin a pull-out lock, so that it can not be pulled out of the terminal compartment of the connector. This is shown in FIGS. 6 to 8.

Fig. 6 zeigt einen Verbinder, der mit dem Ausführungsbeispiel gemäß Fig. 4 vergleichbar ist, jedoch zusätzlich eine Auszugssperre für den Kontaktstift aufweist, der bei diesem Ausführungsbeispiel in der Form der Widerhaken-Verrastungen 31 in den entsprechenden Vertiefungen des Isolierstoffgehäuses des Verbinders wirksam ist.Fig. 6 shows a connector which is comparable to the embodiment of Fig. 4 but which additionally has an extension lock for the contact pin, which in this embodiment is effective in the form of the barb locks 31 in the corresponding recesses of the insulating housing of the connector.

Die Figuren 7 und 8 zeigen zwei Verbinder, deren Isolierstoffgehäuse in der Weise konstruiert und geformt sind, daß beide Verbinder gemeinsam als eine elektr.Steckverbindung verwendbar sind. In ihrem grundsätzlichen Aufbau sind die Verbinder 32 und 33 mit dem Ausführungsbeispiel gemäß Fig. 4 vergleichbar, jedoch ist bei dem links dargestellten Verbinder 32 der Kontaktstift 34 (der beiden Verbindern gemeinsam ist) mit einer Auszugssperre 35 in dem Isolierstoffgehäuse 36 festgelegt, wohingegen bei dem rechts dargestellten Verbinder 33 das Isolierstoffgehäuse 37 von dem (für beide Verbinder gemeinsamen) Kontaktstift 34 abziehbar ist, wodurch die dargestellte elektr.Steckverbindung geöffnet werden kann.Figures 7 and 8 show two connectors whose insulating housings are constructed and shaped in such a way that both connectors can be used together as an electrical connector. In their basic structure are the Connector 32 and 33 with the embodiment of FIG. 4 comparable, however, in the connector 32 shown on the left, the contact pin 34 (the two connectors is common) with a pull-out lock 35 is fixed in the insulating housing 36, whereas in the connector 33 shown on the right Isolierstoffgehäuse 37 is removable from the (common to both connectors) contact pin 34, whereby the electrical connection shown can be opened.

Die Figuren 9 bis 15 zeigen zwei Anwendungsbeispiele für einen Verbinder gemäß der Lehre der Erfindung, um zu demonstrieren, daß diese sehr gut auch als steckbare Anschluß-Verbinder verwendet werden können, die auf abgewinkelten Kontaktstiften aufsteckbar sind, die ihrerseits in eine Leiterplatte eingelötet sind.Figures 9 to 15 show two application examples of a connector according to the teachings of the invention to demonstrate that these can also be used very well as plug-in terminal connectors which can be plugged onto angled contact pins, which in turn are soldered into a printed circuit board.
