Description

Die Erfindung betrifft eine Anschlussleiste der im Oberbegriff des Anspruches 1 näher bezeichneten Ausführung.The invention relates to a terminal block of the design specified in the preamble of claim 1.

Eine derartige Anschlussleiste ist aus der DE-A-2 915 184 bekannt. Die darin beschriebene Schwenkvorrichtung ist Bestandteil des aus einem Blechstreifen hergestellten Kontaktelementes. Der Blechstreifen weist die Form eines liegenden U auf, bei dem der obere Schenkel den Anschlussdraht trägt. Diese Anordnung wird durch Niederdrücken des freien Schenkelendes abgebogen und hierbei in wenigstens einen vom unteren Schenkel aufragenden Schneid- und Klemmanschluss eingedrückt, wobei sich der den Draht tragende Schenkel dauerhaft verriegelt.Such a terminal block is known from DE-A-2 915 184. The swivel device described therein is part of the contact element made from a sheet metal strip. The sheet metal strip has the shape of a lying U, in which the upper leg carries the connecting wire. This arrangement is bent by pressing down the free end of the leg and pressed into at least one cutting and clamping connection projecting from the lower leg, the leg carrying the wire locking permanently.

Aus der DE-B-2 902 536 ist eine Reihenklemme bekannt, mit einer Schwenkvorrichtung, die aus einem als Drehstück ausgeführten Betätigungsglied besteht, welches quer zur Drehachse wenigstens eine Steckbohrung für den anzuschliessenden Draht enthält, die mit einer Leiteraufnahme des Kontaktelements in einer Ebene liegt. Dabei ist die Anordnung so getroffen, dass das als Schwenkhebel ausgebildete Betätigungsglied jeweils einen zum Kontaktelement hinweisenden Gabelkopf aufweist, dessen einer Schenkel eine Durchgangs- und dessen anderer Schenkel eine Sackbohrung zur Aufnahme des anzuschliessenden Drahtes aufweist. Der so in den Gabelkopf eingelegte Anschlussdraht wird bei dem Verschwenken des hebelförmigen Betätigungsgliedes in den Schneid- und Klemmschlitz des Kontaktelements eingedrückt. Dieses Kontaktelement steht mit seinem Schneid- und Klemmbereich frei gegenüber Klemmkörperteilen vor.From DE-B-2 902 536 a terminal block is known, with a pivoting device, which consists of an actuator designed as a rotating piece, which contains transverse to the axis of rotation at least one plug hole for the wire to be connected, which is in one plane with a conductor receptacle of the contact element . The arrangement is such that the actuating element designed as a pivot lever each has a fork head pointing towards the contact element, one leg of which has a through hole and the other leg of which has a blind bore for receiving the wire to be connected. The connecting wire inserted into the fork head in this way is pressed into the cutting and clamping slot of the contact element when the lever-shaped actuator is pivoted. This contact element, with its cutting and clamping area, projects freely relative to clamping body parts.

Aus der DE-A-2 355 873 ist noch ein elektrischer Verbinder bekannt, bei dem die Anschlussdrähte durch im Kreis angeordnete Bohrungen einer Betätigungsscheibe gesteckt und bei Rotationsbewegung dieser Scheibe in die offenen Schneid- und Klemmschlitze der ebenfalls im Kreis angeordneten Kontaktelemente eingedrückt werden.From DE-A-2 355 873 an electrical connector is also known, in which the connecting wires are inserted through bores of an actuating disk arranged in a circle and are pressed into the open cutting and clamping slots of the contact elements also arranged in a circle when this disk rotates.

Ein anderes Ausführungsbeispiel dieses elektrischen Verbinders ist mit einer axialverschieblichen Steckerhülse versehen, bei deren Betätigung radial federnde Anschlüsse der Kontaktelemente in entsprechende, je einen Anschlussdraht aufnehmende Kammern des Steckerkörpers eingedrückt werden, wobei sie die Anschlussdrähte kontaktieren.Another exemplary embodiment of this electrical connector is provided with an axially displaceable plug sleeve, the actuation of which radially resilient connections of the contact elements are pressed into corresponding chambers of the plug body, each receiving a connecting wire, contacting the connecting wires.

Der Erfindung liegt die Aufgabe zugrunde, eine kostengünstig herstellbare Anschlussleiste mit einfach bedienbarer Schwenkvorrichtung zu schaffen, mit der funktionssichere Verbindungen zwischen den Kontaktelementen der Anschlussleiste und den anzuschliessenden Drähten hergestellt und leicht wieder getrennt werden können.The invention has for its object to provide an inexpensive to produce terminal block with an easy-to-use swivel device with which reliable connections between the contact elements of the terminal block and the wires to be connected can be made and easily separated again.

Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen konstruktiven Massnahmen gelöst.This object is achieved according to the invention by the design measures specified in the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen des Gegenstandes nach Anspruch 1 sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the subject matter according to claim 1 can be found in the subclaims.

Die gefundene Lösung bietet verschiedene Vorzüge. Das Drehstück lässt sich ohne besonderen Kraftaufwand mühelos manuell betätigen, wobei der zuvor eingesteckte Anschlussdraht in einer kreisförmigen Bewegung sicher in den Schneid- und Klemmschlitz des Kontaktelementes eingeführt wird. Die Ausführung des Kontaktelementes mit geschlossenen Schneid- und Klemmschlitzenden gestattet eine sehr schmale Festlegung der Breitenabmessung des bandförmigen Kontaktabschnittes, wodurch bei mehrpoliger Ausführung der Anschlussleiste enge Teilungsabstände für die Kontaktelemente möglich sind.The solution found offers various advantages. The rotating piece can be effortlessly operated manually without any special effort, the previously inserted connecting wire being securely inserted into the cutting and clamping slot of the contact element in a circular movement. The design of the contact element with closed cutting and clamping slot ends permits a very narrow definition of the width dimension of the band-shaped contact section, as a result of which narrow pitch spacings for the contact elements are possible with a multipole design of the terminal strip.

Weil das Kontaktelement zugleich die Halterung des Drehstückes darstellt, entfallen zusätzliche Befestigungsteile.Because the contact element also represents the holder of the rotating piece, additional fastening parts are not required.

Weitere Vorteile sind in der Beschreibung genannt.Further advantages are mentioned in the description.

Die Erfindung wird anhand von in Zeichnungen dargestellten Ausführungsbeispielen wie folgt näher beschrieben.The invention is described in more detail with reference to exemplary embodiments shown in the drawings as follows.

In the drawings:
  • Figure 1 is a plug-in terminal block with several unactuated and one actuated rotary piece, partially cut, in the front view.
  • Fig. 2 shows the terminal block of Figure 1 in plan view.
  • Fig. 3 shows the terminal block of Fig. 1 in a cross-sectional view;
  • 4 shows a version of the terminal block, used for attachment to printed circuit boards, cross-sectioned;
  • 5 a terminal strip similar to FIG. 4 for multiple contacting of the connecting wire in a cross-sectional view.

In den Fig. 1 bis 5 ist die Anschlussleiste allgemein mit 1 bezeichnet. Sie besteht im wesentlichen aus einem Gehäuse 2, in dem wenigstens ein Kontaktelement 3 und eine aus einem Drehstück 4 bestehende Schwenkvorrichtung angeordnet ist.1 to 5, the terminal block is generally designated 1. It essentially consists of a housing 2, in which at least one contact element 3 and a swivel device consisting of a rotating piece 4 are arranged.

Wie insbesondere die Fig. 3 bis 5 veranschaulichen, weist das Drehstück 4 ein Halteteil 5 auf, mit dem es im Gehäuse 2 befestigt ist. Als Befestigungsmittel wird in vorteilhafter Weise das Kontaktelement 3 selbst verwendet. Letzteres ist mit einem bandförmigen Abschnitt 6 versehen, welcher das Halteteil 5 teilweise umschlingt und dessen Bandenden in oder an der Grundplatte 7 des Gehäuses 2 befestigt sind.3 to 5 in particular, the rotary piece 4 has a holding part 5 with which it is fastened in the housing 2. The contact element 3 itself is advantageously used as the fastening means. The latter is provided with a band-shaped section 6 which partially wraps around the holding part 5 and the band ends of which are fastened in or on the base plate 7 of the housing 2.

Das Halteteil 5 ist als Zapfen ausgebildet, dessen Längsachse die Drehachse der Schwenkvorrichtung darstellt. Quer zur Drehachse enthält der Zapfen zur Führung eines anzuschliessenden Drahtes 8 wenigstens eine Einstecköffnung 9, die mit dem im kreisförmigen Bogenteil des Kontaktelementes 3 enthaltenen Schneid- und Klemmschlitz 10 in einer Ebene liegt. Der Schneid- und Klemmschlitz 10 ist nicht nur, wie üblich, am unteren Ende geschlossen, sondern auch am oberen Anfang.The holding part 5 is designed as a pin, the longitudinal axis of which represents the axis of rotation of the swivel device. Transverse to the axis of rotation, the pin for guiding a wire 8 to be connected contains at least one insertion opening 9 which lies in one plane with the cutting and clamping slot 10 contained in the circular arc part of the contact element 3. The cutting and clamping slot 10 is not only closed at the lower end, as is customary, but also at the upper beginning.

Am Beginn des Schneid- und Klemmschlitzes 10 ist jedoch eine bei unbetätigtem Drehstück 4 mit der Einstecköffnung 9 des Zapfens fluchtende Durchstecköffnung 11 angeordnet (Fig. 2). Zweckmässigerweise ist auch in dem als Betätigungshebel 12 wirkenden Teil des Drehstückes 4 eine mit der Durchstecköffnung 11 im Kontaktelement und der Einstecköffnung 9 im Halteteil 5 fluchtende Drahtführung 13 vorgesehen. Diese ist, wie die in den Fig. 3 bis 5 dargestellten Ausführungsbeispiele der Anschlussleiste 1 zeigen, als konische Durchgangsbohrung ausgebildet. Die Funktion der Drahtführung 13 kann aber auch von einer an der Unterseite des Betätigungshebels 12 eingeformten Nut erfüllt werden.At the beginning of the cutting and clamping slot 10, however, a through-opening 11, which is aligned with the insertion opening 9 of the pin when the rotating piece 4 is not actuated, is arranged (FIG. 2). A wire guide 13 which is aligned with the push-through opening 11 in the contact element and the push-in opening 9 in the holding part 5 is also expediently provided in the part of the rotary piece 4 which acts as an actuating lever 12. This is, as the exemplary embodiments of the terminal block 1 shown in FIGS. 3 to 5 show, designed as a conical through hole. The function of the wire guide 13 can also be fulfilled by a groove formed on the underside of the actuating lever 12.

Die miteinander fluchtenden Achsen von Drahtführung 13, Durch- und Einstecköffnung 11, 9 schliessen bei unbetätigtem Drehstück 4 einen Winkel < 90° und > 30° mit der Grundplatte 7 des Gehäuses ein. Zum Herstellen einer Verbindung mit dem Kontaktelement 3 der Anschlussleiste 1 wird der Draht 8 also schräg in das Drehstück 4 eingesetzt und zwar so tief, bis sein Ende gegen den Boden der als Sackloch ausgeführten Einstecköffnung 9 im Zapfen stösst. Beim Niederdrücken des Betätigungshebels 12 wird der Draht 8 in den Schneid- und Klemmschlitz 10 und ausserhalb des Drehstückes 4 zur zugentlasteten Halterung gleichzeitig auch zwischen die Federzungen von pilzartig geformten Niederhaltern 14 des Gehäuses 2 eingedrückt. Das Niederdrücken des Betätigungshebels 12 ist ohne weiteres manuell vornehmbar, jedoch kann dies auch mittels eines Schraubendrehers erfolgen, dessen Spitze dann in eine oberhalb der Drahtaufnahmeöffnung 13 angeordnete Ausnehmung 15 eingesetzt wird.The axially aligned axes of wire guide 13, through and insertion opening 11, 9 form an angle of <90 ° and> 30 ° with the base plate 7 of the housing when the rotary piece 4 is not actuated. To establish a connection with the contact element 3 of the terminal block 1, the wire 8 is thus inserted obliquely into the rotating piece 4 and so deep until its end abuts the bottom of the insertion opening 9 in the pin, which is designed as a blind hole. When the actuating lever 12 is pressed down, the wire 8 is simultaneously pressed into the cutting and clamping slot 10 and outside of the rotary piece 4 for the strain-relieved mounting between the spring tongues of mushroom-shaped holding-down devices 14 of the housing 2. Depressing the actuating lever 12 can easily be done manually, but this can also be done by means of a screwdriver, the tip of which is then inserted into a recess 15 arranged above the wire receiving opening 13.

Das Drehstück 4 weist in vorteilhafter Weise zwei Raststellungen auf. Eine erste Raststellung hält es in der unbetätigten, offenen Lage, während die zweite Raststellung ein Selbstlösen des betätigten Drehstückes bzw. seines eingeklemmten Drahtes 8 verhindert. Die Raststellungen werden, wie es beispielsweise in den Fig. 3 und 4 dargestellt ist, von einem im bandförmigen Abschnitt 6 des Kontaktelementes 3 durchgedrückten Rastnocken 16 und zwei passenden Rastkerben 17 im Zapfen des Drehstückes 4 gebildet. Sie können aber auch mittels entsprechender, z.B. zwischen Drehstück 4 und Gehäuse 2 wirkender Anordnungen realisiert sein.The rotating piece 4 advantageously has two locking positions. A first latching position keeps it in the unactuated, open position, while the second latching position prevents the actuated rotating piece or its pinched wire 8 from loosening itself. 3 and 4, the latching positions are formed by a latching cam 16 pushed through in the band-shaped section 6 of the contact element 3 and two suitable latching notches 17 in the journal of the rotating piece 4. However, you can also use appropriate, e.g. arrangements acting between the rotating piece 4 and the housing 2 can be realized.

Um das beim Anschliessen eines Drahtes 8 mögliche Verkanten des Drehstückes zu vermeiden, weist letzteres ein scheibenförmiges Segment 18 auf, das in einem komplementären Schlitz des Gehäuses 2 geführt ist. Sind innerhalb eines Gehäuses 2 mehrere Drehstücke 4 aneinandergereiht, kann noch eine weitere Führung vorgesehen werden, welche die während des Betätigens eines Drehstückes 4 auftretenden Kräfte auf benachbarte Drehstücke verteilt. Die zusätzliche Führung besteht aus einem auf einer Seite des Drehstückes 4 hervorstehenden Zapfen 19, der jeweils in die auf der anderen Seite entsprechend angeordnete Vertiefung 20 eines benachbarten Drehstückes 4 eingreift (Fig. 1). Die Seitenwände des Gehäuses 2 sind dann innen mit den gleichen Ausbildungen versehen.In order to avoid the tilting of the rotating piece when a wire 8 is connected, the rotating piece has a disk-shaped segment 18 which is guided in a complementary slot in the housing 2. If a plurality of rotary pieces 4 are lined up within a housing 2, a further guide can be provided which distributes the forces occurring during the actuation of a rotary piece 4 to adjacent rotary pieces. The additional guide consists of a pin 19 projecting on one side of the rotating piece 4, which engages in the correspondingly arranged recess 20 of an adjacent rotating piece 4 on the other side (FIG. 1). The side walls of the housing 2 are then provided with the same formations on the inside.

Die Fig. 1 und 2 lassen erkennen, dass der bandförmige Abschnitt 6 des Kontaktelementes 3 schmaler als das Drehstück 4 ist und vollkommen versenkt in einem das Halteteil 5 freistellenden Schlitz 21 steckt, welcher von einer Seite aus in das Drehstück 4 eingeformt ist. Bei dem in Fig. 5 dargestellten Ausführungsbeispiel der Anschlussleiste 1 ist in parallelem Abstand zum Schlitz 21 ein weiterer Schlitz 22 für die Aufnahme eines zweiten Kontaktelementes 23 angeordnet, wodurch der Vorteil einer voneinander unabhängigen, doppelten Drahtkontaktierung erzielt wird.1 and 2 show that the band-shaped section 6 of the contact element 3 is narrower than the rotating piece 4 and is completely recessed in a slot 21 which exposes the holding part 5 and which is formed into the rotating piece 4 from one side. In the exemplary embodiment of the terminal strip 1 shown in FIG. 5, a further slot 22 for receiving a second contact element 23 is arranged parallel to the slot 21, whereby the advantage of an independent, double wire contact is achieved.

Die verlängerten Enden der in der Anschlussleisten-Grundplatte 7 festgelegten bandförmigen Kontaktelemente-Abschnitte 6 sind je nach Verwendungszweck unterschiedlich gestaltet. Gemäss den Fig. 1 bis 3 ist ein in der Verlängerung schmaler ausgeführtes Bandende in der Materialdicke durch Zurückfalten verdoppelt und als Stekkerstift 24 ausgebildet. Ein derartiges Bandende kann bedarfsweise jedoch auch als Pfosten für den Anschluss von Drahtwickelverbindungen benutzt werden. Es lässt sich ausserdem z.B. als Gabelkontaktfeder oder Lötfahne ausbilden. Natürlich ist auch das Vorsehen von Kombinationen solcher Anschlüsse möglich. Beispielsweise kann ein Ende des Bandabschnittes 6 als Steckerstift und das andere Bandende als Lötfahne und/oder Steckzunge ausgebildet sein; oder, wie es Fig. 4 und 5 zeigen, dass jedes Bandende den gleichen Anschluss aufweist.The extended ends of the band-shaped contact element sections 6 fixed in the terminal strip base plate 7 are designed differently depending on the intended use. According to FIGS. 1 to 3, a strip end which is made narrower in the extension is doubled in the material thickness by folding back and is designed as a plug pin 24. However, if required, such a tape end can also be used as a post for the connection of wire winding connections. It can also be e.g. Design as a fork contact spring or soldering tag. Of course, it is also possible to provide combinations of such connections. For example, one end of the band section 6 can be designed as a plug pin and the other end of the band as a soldering tab and / or tongue; or, as shown in FIGS. 4 and 5, that each band end has the same connection.

Bei dem mit Steckerstiften 24 versehenen Ausführungsbeispiel weist das Gehäuse 2 der Anschlussleiste 1 einen alle Steckerstifte gemeinsam umgebenden Kragen 25 auf, der beim Stecken das entsprechend gestaltete Gehäuse einer komplementären Buchsenleiste übergreift (nicht dargestellt). Im übrigen weist das Gehäuse 2 eine im wesentlichen kastenartige Form auf. Die Enden der Kontaktelemente 3, 23 sind darin entweder stoffschlüssig, wie z.B. durch Anwenden des Ultraschall-Schweissverfahrens oder kraftschlüssig, beispielsweise mittels Schnappverbindung oder durch Verschränken lösbar befestigt. Wie die Fig. 4 und 5 veranschaulichen, bilden die verlängert ausgeführten Befestigungsenden der Kontaktelemente 3, 23 Anschlussfahnen für das Einlöten in gedruckte Leiterplatten 26.In the exemplary embodiment provided with plug pins 24, the housing 2 of the connection strip 1 has a collar 25 which surrounds all the plug pins and which, when plugged in, engages over the correspondingly designed housing of a complementary socket strip (not shown). Otherwise, the housing 2 has an essentially box-like shape. The ends of the contact elements 3, 23 are either integral, e.g. detachably attached by applying the ultrasonic welding process or non-positively, for example by means of a snap connection or by entangling. 4 and 5 illustrate, the elongated fastening ends of the contact elements 3, 23 form connection lugs for soldering into printed circuit boards 26.

Das Gehäuse 2 der Anschlussleiste 1 und ihre Drehstücke 4 bestehen jeweils aus einstückig gespritzten Isolierkörpern. Während bei den zuvor anhand von Zeichnungen beschriebenen Ausführungsbeispielen in einem Gehäuse 2 mehrere angereihte Drehstücke 4 angeordnet sind, besteht bei einem nicht dargestellten Beispiel das Gehäuse aus anreihbaren, z.B. mittels Schwalbenschwanzführung oder druckknopfartig zusammengefügten Einzelabschnitten, die je ein Drehstück 4 mit wenigstens einem Kontaktelement 3 enthalten.The housing 2 of the terminal block 1 and its rotating pieces 4 each consist of integrally molded insulating bodies. While in the exemplary embodiments described above with reference to drawings, a plurality of rotating pieces 4 are arranged in a housing 2, in an example which is not shown, the housing consists of stackable, e.g. by means of dovetail guides or individual sections joined together like a push button, each of which contains a rotary piece 4 with at least one contact element 3.

Unabhängig davon, ob das Gehäuse 2 der Anschlussleiste 1 einstückig hergestellt ist oder aus zusammengefügten Einzelabschnitten besteht, weist es für die Montage auf gedruckten Leiterplatten 26 an der Unterseite 27 seiner Grundplatte 7 zweckmässigerweise eine umlaufende Leiste oder mehrere Distanzstücke 28 auf.Regardless of whether the housing 2 of the terminal block 1 is made in one piece or from consists of assembled individual sections, it expediently has a circumferential strip or a plurality of spacers 28 for mounting on printed circuit boards 26 on the underside 27 of its base plate 7.
