In order to give a safe locking connection in a compact design as well as partial equipping and mixed equipping between i.p.c.d and crimp connections, a combination of lockable flat-pin or spade sleeves or bushing with an i.p.c.d. connection (3) or terminal is used.

Description

Die Erfindung betrifft einen Steckverbinder zur Einzelkontaktierung oder simultanen Kontaktierung von mit Flachsteckern versehenen Geräten, die eine Mehrzahl von Kontakten aufweisen, insbesondere von Steuergeräten, wie Timern, wie sie in der Weißgeräte-Industrie bei einer maximalen Polzahl von zwölf Kontakten Verwendung finden.The invention relates to a connector for individual contacting or simultaneous contacting of devices provided with flat plugs which have a plurality of contacts, in particular of control devices, such as timers, as are used in the white goods industry with a maximum number of poles of twelve contacts.

Eine verriegelbare Flachsteckhülse ist beispielsweise aus der europäischen Patentschrift 0 024 981 bekannt. Sie ist Teil einer elektrischen Verbindungsvorrichtung, bei der ein bekannter Flachstecker in Form einer rechteckigen Platte zur elektrischen Kontaktierung in die Flachsteckhülse eingeschoben und lösbar verriegelt wird. Nachteilig ist dabei, daß der elektrische Leiter mit der Flachsteckhülse immer durch eine Crimp-Verbindung verbunden wird, die hierzu ein für die Crimp-Technik geeignetes Steckbuchsenendstück aufweist. Eine Anwendung dieser bekannten Flachsteckhülse verbietet sich daher überall dort, wo Kabelbäume Verwendung finden sollen, deren elektrisches Kontaktelement in Schneidklemmtechnik ausgebildet ist.A lockable flat receptacle is known for example from European patent 0 024 981. It is part of an electrical connection device in which a known flat plug in the form of a rectangular plate for electrical contacting is inserted into the flat plug sleeve and releasably locked. The disadvantage here is that the electrical conductor is always connected to the flat receptacle by a crimp connection which has a socket end piece suitable for the crimping technique for this purpose. The use of this known flat receptacle is therefore forbidden wherever cable harnesses are to be used, the electrical contact element of which is formed in insulation displacement technology.

Elektrische Kontaktelemente in dieser sogenannten Schneidklemmtechnik sind aus der DE-PS 39 29 828 für elektrische Kabelsteckverbindungen bekannt. Sie werden aus einem Blech ausgestanzt und entsprechend der vorgegebenen Form gebogen. Zum Zwecke der Kontaktierung weist das elektrische Kontaktelement wenigstens eine Gabelfeder auf, die zwischen sich einen Einführschlitz definiert, wobei die einander zugewandten Kanten der beiden Gabelfederschenkel angeschärft sind. Um das elektrische Kabel zu kontaktieren, wird dieses in den Einführschlitz der Gabelfeder eingeführt, so daß die Schneiden der beiden Gabelfederschenkel die Kabelisolierung derart einritzen, daß sie mit dem elektrischen Leiter in elektrischen Kontakt gelangen. Die beiden Gabelfederschenkel üben dabei eine Klemmkraft auf den elektrischen Leiter aus, so daß dieser in dem Einführschlitz gehalten ist. Bei der Anwendung eines derartigen Kontaktelementes in Schneidklemmtechnik ist nachteilig, daß die Federzungen, zwischen die beispielsweise der Kontaktstift eines Steckers der elektrischen Steckverbindung zur elektrischen Kontaktierung eingeschoben wird, keinerlei Verriegelung aufweisen. Es werden daher zur Sicherung der elektrischen Verbindung Gehäuse verwendet, die mit äußeren Rastarmen ausgerüstet sind, welche nachteiligerweise Platz beanspruchen und schließlich wegen der Gefahr des Abbrechens auch keine sichere Verriegelung gewährleisten.Electrical contact elements in this so-called insulation displacement technology are known from DE-PS 39 29 828 for electrical cable connectors. They are punched out of a sheet and bent according to the given shape. For the purpose of contacting, the electrical contact element has at least one fork spring which defines an insertion slot between them, the mutually facing edges of the two fork spring legs being sharpened. To contact the electrical cable, this is inserted into the insertion slot of the fork spring, see above that the cutting of the two fork spring legs carve the cable insulation in such a way that they come into electrical contact with the electrical conductor. The two fork spring legs exert a clamping force on the electrical conductor so that it is held in the insertion slot. When using such a contact element in insulation displacement technology, it is disadvantageous that the spring tongues, between which, for example, the contact pin of a plug of the electrical plug connection for electrical contacting is inserted, have no locking. To secure the electrical connection, therefore, housings are used which are equipped with outer latching arms, which disadvantageously take up space and, ultimately, do not ensure secure locking because of the risk of breaking off.

Der Erfindung liegt in Anbetracht dieses Standes der Technik die Aufgabe zugrunde, einen Steckverbinder der eingangs genannten Art derart zu verbessern, daß eine sichere, platzsparende Verriegelung gegeben ist und sowohl eine Teilbestückung als auch eine Mischbestückung zwischen Schneidkontaktanschluß und Crimp-Anschluß ermöglicht ist, so daß sämtliche von der Geräteindustrie vorgegebenen Anschlußarten in einfacher Weise Verwendung finden können.In view of this prior art, the invention has for its object to improve a connector of the type mentioned in such a way that a secure, space-saving locking is given and both a partial assembly and a mixed assembly between the cutting contact connection and crimp connection is possible, so that all connection types specified by the equipment industry can be used in a simple manner.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß der Steckverbinder der eingangs genannten Art durch die Kombination einer verriegelbaren Flachsteckhülse mit einem Schneidklemmanschluß gekennzeichnet ist. Hiermit wird erreicht, daß eine sichere innere Verriegelung möglich ist, so daß Gehäuse ohne Verriegelungsarme Verwendung finden können. Somit wird ein erheblicher Platzgewinn erreicht. Darüber hinaus ermöglicht der erfindungsgemäß vorgesehene Schneidklemmanschluß die Verwendung bekannter Ansetzmaschinen für ein simultanes Ansetzen und Bestücken, wobei etwaige Verbindungsbrücken, die aus maschinentechnischen Gründen nicht in der Schneidklemm-Technik möglich sind, nachträglich mittels Crimp-Verbindungen gemäß einer zweckmäßigen Ausgestaltung der Erfindung eingebracht werden können. Die Herstellung beliebiger Kabelsätze mit verschiedenen Anschlußarten an einem Artikel ist möglich. Die erfindungsgemäßen Steckverbinder passen in Gehäuse, die Rasterabstände von 5mm aufweisen, wobei bei diesen Gehäusen die bislang verwendeten Außenrastarme entfallen können, da das Rastproblem durch die Verriegelung der Flachsteckhülse übernommen wird.The object is achieved in that the connector of the type mentioned is characterized by the combination of a lockable flat receptacle with an insulation displacement connection. This ensures that a secure internal locking is possible so that housings can be used without locking arms. A considerable amount of space is thus achieved. In addition, the insulation displacement connection provided according to the invention enables the use of known attaching machines for simultaneous attachment and fitting, wherein any connecting bridges that are not possible in insulation displacement technology for technical reasons can be subsequently inserted by means of crimp connections according to an expedient embodiment of the invention. The production of any cable sets with different connection types on one article is possible. The plug connectors according to the invention fit into housings which have a grid spacing of 5 mm, with these housings eliminating the external latch arms used up to now can, because the locking problem is taken over by locking the blade receptacle.

Gemäß einer zweckmäßigen Ausgestaltung der Erfindung weist die verriegelbare Flachsteckhülse einen Unterbringungsraum für den Flachstecker auf, der aus einer Fußplatte mit zwei Seitenwänden besteht, deren beiden freien Ränder oberhalb der Fußplatte nach innen abgewinkelt sind, wobei die Fußplatte eine Verriegelungsklemme mit einem Zuhaltungshaken aufweist, der in eine im Flachstecker ausgebildete Ausnehmung mittels einer Freigabeeinrichtung lösbar einrastet. Eine solche Flachsteckhülse zeichnet sich dadurch aus, daß nur eine geringe Kraft für das Zusammenstecken benötigt wird, daß durch die Verrastung sodann eine sichere Verbindung gewährleistet ist und dennoch eine gewollte Trennung jederzeit möglich ist.According to an expedient embodiment of the invention, the lockable flat receptacle has an accommodation space for the flat plug, which consists of a base plate with two side walls, the two free edges of which are angled inwards above the base plate, the base plate having a locking clamp with a tumbler hook which is in a recess formed in the flat plug detachably engages by means of a release device. Such a flat receptacle is characterized in that only a small force is required for the plugging together, that a secure connection is then ensured by the latching and nevertheless a deliberate separation is possible at any time.

Zur Ausbildung des Schneidklemmanschlusses wird vorteilhafterweise am erfindungsgemäßen Steckverbinder vorgeschlagen, eine Seitenwand zu verlängern und rechtwinklig abzubiegen, wobei die Abbindung als Schneidklemme mit Gabelfeder und Schneidschlitz in an sich bekannter Weise versehen wird. Dabei können auch mehrere Gabelfedern hintereinander koaxial zur Flachsteckhülse vorgesehen sein. Dabei ist es aus Platzgründen zweckmäßig, die Gabelfedern durch mäanderförmiges Abbiegen und/oder durch Biegeansätze an der verlängerten Seitenwand zu bilden.To form the insulation displacement connection, it is advantageously proposed on the connector according to the invention to extend a side wall and bend it at right angles, the binding being provided as an insulation displacement clamp with a fork spring and a cutting slot in a manner known per se. Several fork springs can also be provided one behind the other coaxially to the flat receptacle. For reasons of space, it is expedient to form the fork springs by meandering bending and / or by bending approaches on the extended side wall.

Gemäß einer weiteren vorteilhaften Ausführungsform kann ergänzend zu dem oder den Anschlüssen in Schneidklemmtechnik ein Crimp-Anschluß vorgesehen sein.According to a further advantageous embodiment, a crimp connection can be provided in addition to the connection or connections using insulation displacement technology.

Die in der Zeichnung dargestellten Steckverbinder 1 stellen eine Kombination einer verriegelbaren Flachsteckhülse 2 mit einem Schneidklemmanschluß 3 dar. Als Material wird eine Kupfer-Zinn-Legierung verwendet, wobei die Kontaktoberfläche verzinnt sein kann. Die Herstellung erfolgt aus einem Blechstreifen durch Stanzen, Biegen und Prägen, wobei eine Abwicklung gemäß Fig. 5 der Zeichnung verdeutlicht, welche Bearbeitungsvorgänge erforderlich sind, um einen Steckverbinder gemäß Fig. 4 der Zeichnung herzustellen.The connectors 1 shown in the drawing represent a combination of a lockable flat receptacle 2 with an insulation displacement connection 3. A copper-tin alloy is used as the material, and the contact surface can be tinned. The production takes place from a sheet metal strip by punching, bending and embossing, a development according to FIG. 5 of the drawing clarifying which machining processes are required to produce a connector according to FIG. 4 of the drawing.

Die verriegelbare Flachsteckhülse 2 weist eine Fußplatte 4 mit zwei Seitenwänden 5, 6 auf, die im wesentlichen senkrecht hochgebogen sind und deren beiden freien Ränder 7, 8 nach innen eingebogen sind, um einen kastenförmigen Unterbringungsraum für einen Flachstecker 9 zu bilden. Um ein gleitendes Einschieben mit leichter Aufsteckkraft zu gewährleisten, sind die freien Ränder 7, 8 mit einer geringen Einprägung versehen, so daß sich ein leicht bogenförmiger Verlauf ergibt. Jegliches Spiel zwischen dem Flachstecker 9 indem aus der Fußplatte 4, den beiden Seitenwänden 5 und 6 sowie den freien Rändern 7 und 8 gebildeten Unterbringungsraum ist vermieden, wobei durch die Einbiegung der freien Rändern ein guter Kontakt zwischen der Flachsteckhülse 2 und dem Flachstecker 9 gewährleistet ist.The lockable flat receptacle 2 has a base plate 4 with two side walls 5, 6, which are bent up substantially vertically and the two free edges 7, 8 of which are bent inwards in order to form a box-shaped accommodation space for a flat plug 9. In order to ensure a sliding insertion with a slight push-on force, the free edges 7, 8 are provided with a slight embossing, so that there is a slightly curved course. Any play between the flat plug 9 by the accommodation space formed from the base plate 4, the two side walls 5 and 6 and the free edges 7 and 8 is avoided, and good contact between the flat plug sleeve 2 and the flat plug 9 is ensured by the bending of the free edges .

In der Fußplatte 4 ist ein Zuhaltungshaken 10 herausgearbeitet, der mit einem Loch 11 des Flachsteckers 9 als Verriegelungsklemme zusammenwirkt. Um deren Lösbarkeit bereitzustellen, findet sich in der Fußplatte 4 ein im wesentlichen U-förmiger Ausschnitt 12, dessen freies Ende hochgebogen ist und eine Freigabeeinrichtung 13 bildet. Durch Druck auf die Freigabeeinrichtung 13 ist die durch den U-förmigen Ausschnitt 12 gebildete Zunge elastisch nach unten zu bewegen, so daß der Zuhaltungshaken 10 nicht mehr in das Loch 11 des Flachsteckers 9 eingreift und dieser aus der Verbindung lösbar ist.A tumbler hook 10 is worked out in the base plate 4, which interacts with a hole 11 in the flat plug 9 as a locking clamp. In order to provide their releasability, there is an essentially U-shaped cutout 12 in the base plate 4, the free end of which is bent up and forms a release device 13. By pressing the release device 13, the tongue formed by the U-shaped cutout 12 can be moved elastically downward, so that the tumbler hook 10 no longer engages in the hole 11 of the tab 9 and the latter can be released from the connection.

Die Seitenwand 5 der Flachsteckhülse 2 ist in der Zeichnung nach links verlängert und rechtwinklig nach innen abgebogen. Um an diese Abbiegung ein elektrisches Kabel 14 in Schneidklemmtechnik kontaktieren zu können, weist die Abwinklung eine Gabelfeder 15 auf, deren Schenke zwischen sich einen Einführschlitz 16 für das elektrische Kabel 14 definieren.The side wall 5 of the flat receptacle 2 is extended to the left in the drawing and bent inwards at right angles. In order to be able to contact an electrical cable 14 using insulation displacement technology at this bend, the bend has a fork spring 15, the legs of which define an insertion slot 16 between them for the electrical cable 14.

Zum Kontaktieren des elektrischen Kabels 14 wird dieses - in der Lage gemäß Zeichnung - von unten in den Einführschlitz 16 hineingesteckt, wobei durch eine Anschärfung der beiden einander zugewandten Kanten der Gabelfeder sich deren Schenkel in die Isolierung des elektrischen Kabels 14 einschneiden und somit den elektrischen Kontakt herstellen.To contact the electrical cable 14, this - in the position shown in the drawing - is inserted from below into the insertion slot 16, the legs of the fork spring cutting into the insulation of the electrical cable 14 and thus the electrical contact by sharpening the two mutually facing edges of the fork spring produce.

In den in den Figuren 2 und 3 dargestellten Ausführungsformen eines erfindungsgemäßen Steckverbinders sind allein gegenüber der vorbeschriebenen Ausführungsform die Schneidklemmanschlüsse vervielfältigt. So ist bei der Ausführungsform gemäß Fig. 2 die beschriebene Verlängerung der Seitenwand 5 der Flachsteckhülse 2 mäanderförmig abgewinkelt, so daß eine zusätzliche Gabelfeder 17 als zweiter Schneidklemmanschluß durch eine entsprechende Stanzung des Materials gebildet ist. Entsprechend ist bei der Ausführungsform gemäß Fig. 3 der Zeichnung eine erneute mäanderförmige Rückführung des freien Endes der verlängerten Seitenwand zur Ausbildung eines dritten Schneidklemmanschlusses 18 vorgesehen.In the embodiments of a connector according to the invention shown in FIGS. 2 and 3, the insulation displacement connections are duplicated only in comparison with the embodiment described above. Thus, in the embodiment according to FIG. 2, the described extension of the side wall 5 of the flat receptacle 2 is angled in a meandering manner, so that an additional fork spring 17 is formed as a second insulation displacement connection by a corresponding punching of the material. Correspondingly, in the embodiment according to FIG. 3 of the drawing, a renewed meandering return of the free end of the extended side wall is provided to form a third insulation displacement connection 18.

Anstelle dieser Herstellungsart der Schneidklemmanschlüsse durch mäanderförmiges Abbiegen der verlängerten Seitenwand 13, ist bei der in den Figuren 4 und 5 dargestellten Ausführungsform vorgesehen, die Gabelfeder 15 als ersten Schneidklemmanschluß und 17 als zweiten Schneidklemmanschluß mittels eines formgerecht gestanzten Biegeansatzes 19 auszubilden, während der dritte Schneidklemmanschluß 18 wie bei den vorbeschriebenen Ausführungsformen durch Abbiegen der verlängerten Seitenwand 5 der Flachsteckhülse 2 hergestellt wird. Hiermit wird eine größere Festigkeit und Sicherheit gegen ein Verbiegen beim Kontaktieren mit dem Draht erzielt.Instead of this type of manufacture of the insulation displacement connections by meandering bending of the elongated side wall 13, the fork spring 15 is provided in the embodiment shown in FIGS. 4 and 5 as the first insulation displacement connection and 17 as the second insulation displacement connection by means of a form-stamped bending attachment 19, while the third insulation displacement connection 18 is produced, as in the previously described embodiments, by bending the elongated side wall 5 of the flat receptacle 2. This provides greater strength and security against bending when contacting the wire.

Bei der in Fig. 6 der Zeichnung dargestellten Ausführungsform eines Steckverbinders ist ein zusätzlicher Crimp-Anschluß 20 in Reihe mit den Schneidklemmanschlüssen an der Flachsteckhülse 2 vorgesehen.In the embodiment of a connector shown in FIG. 6 of the drawing, an additional crimp connection 20 is provided in series with the insulation displacement connections on the flat receptacle 2.
