Description

Die vorliegende Erfindung betrifft eine Steckerbrücke mit einer Grundplatte und mit mindestens einem diese Grundplatte durchdringenden Steckerhohlstift. Des Weiteren betrifft die Erfindung einen Steckerhohlstift zur Aufnahme in einer Steckerbrücke, umfassend einen steckdosenseitigen Steckbereich, einen in der Steckerbrücke befestigbaren Haltebereich und einen Anschlussbereich für ein Netzkabel.The present invention relates to a connector bridge with a base plate and at least one of these base plate penetrating plug hollow pin. Furthermore, the invention relates to a plug hollow pin for receiving in a connector bridge, comprising a socket-side plug-in area, a fixable in the connector bridge holding area and a connection area for a power cord.

Eine bekannte derartige Steckerbrücke einschließlich eines entsprechenden Steckerstiftes ist in der WO 03/092123 A1 beschrieben. Bei dieser Steckerbrücke ist der steckdosenseitig offene Hohlraum des Hohlstiftes mit einer Abdichtung gegen Grundplattenmasseneindringen bei der Steckerbrückenfertigung versehen. Der Hohlstift der bekannten Steckerbrücke wird aus einem gestanzten und/oder geprägten Blechstück gebogen und stellt somit ein sogenanntes Stanz- oder Prägebiegeteil dar.A known such connector bridge including a corresponding pin is in the WO 03/092123 A1 described. In this connector bridge of the socket side open cavity of the hollow pin is provided with a seal against Grundplattenmasseneindringen in the connector bridge production. The hollow pin of the known connector bridge is bent from a stamped and / or embossed sheet metal piece and thus represents a so-called stamped or stamped bent part.

In der WO 03/092123 A1 ist auch die Funktion einer Steckerbrücke der eingangs genannten Art beschrieben. Es handelt sich dabei um ein Teil eines Netzsteckers, in dem die Verbindung zwischen von in die Steckdose einzuschiebenden Kontakten, insbesondere den Steckerstiften, einerseits und den abisolierten Litzen eines Netzanschlusskabels andererseits erfolgt. Die Steckerbrücke umschließt dabei die Stifte in der für die jeweilige elektrische Norm korrekten geometrischen Ausrichtung und weist auf der Seite des Litzenanschlusses Verbindungsmöglichkeiten, wie Crimpflügel zum Vercrimpen mit den Leitungen, Lötfahnen, Einführtrichter für die Vercrimpung oder Verschraubung oder ähnliche andere Elemente, auf.In the WO 03/092123 A1 is also described the function of a connector bridge of the type mentioned. It is a part of a power plug, in which the connection between the contacts to be inserted into the socket, in particular the plug pins, on the one hand and the stripped strands of a power cord on the other hand takes place. The plug bridge encloses the pins in the proper electrical alignment for the correct geometric alignment and has on the side of the Litzenanschlusses connection options, such as Crimpflügel for crimping with the lines, Lötfahnen, insertion crimp or screwing or other similar elements on.

In dem genannten Dokument ist auch ein Teil der Problematik beschrieben, die mit dem Einsatz von Hohlstiften in bekannten Steckerbrücken verbunden ist. Zwar ist wegen eines geringeren Materialaufwandes und einer technologisch weniger aufwändigen Fertigung sowie wegen einer Gewichtsersparnis beim Transport der Einsatz eines Hohlstiftes im Vergleich mit einem Steckerstift, dessen Form aus dem Vollen gedreht wird, vorteilhaft, beim üblichen Umspritzen der Hohlstift-Steckerkontakte mit dem die Steckerbrücke bildenden Kunststoff besteht jedoch nachteiligerweise die Möglichkeit, dass Kunststoffmaterial in den Hohlraum des Steckerstiftes eindringt. Da aber nach den geltenden Sicherheitsvorschriften kein Kunststoffmaterial der Steckerbrücke in den Hohlraum des Steckerstiftes eindringen darf, besteht keine Möglichkeit, wasserdichte Stecker mit Hohlstift-Kontakten auszurüsten. Dadurch, dass der steckdosenseitig offene Hohlraum gemäß der WO 03/092123 A1 des Hohlstiftes mit einer Abdichtung versehen ist, soll diesem Problem abgeholfen werden. Die bekannte technische Lösung vermag jedoch nicht zu verhindern, dass Wasser oder Feuchtigkeit in das Innere des steckdosenseitigen Teils des Hohlstiftes eindringt und dort eine Korrosion verursacht, was ebenfalls eine langfristige Stabilität des Steckers und damit dessen Verwendbarkeit im Außenbereich, in Feuchträumen und dergleichen in Frage stellen kann. Außerdem wird durch ein Stanz- oder Prägebiegeteil als Steckerstift der bekannten Art aufgrund des Vorhandenseins der mit der Fertigung entstehenden Längsnaht keine vollständige Rundheit bzw. Formstabilität im Querschnitt erreicht, was zu Schwierigkeiten beim Stecken führen kann.The cited document also describes a part of the problem associated with the use of hollow pins in known connector bridges. Although the use of a hollow pin in comparison with a pin, whose shape is turned from solid, is advantageous in the conventional encapsulation of the hollow pin connector contacts with the plug bridge forming due to a lower cost of materials and a less technologically complex production However, plastic is disadvantageously the possibility that plastic material penetrates into the cavity of the connector pin. Since, however, according to the current safety regulations no plastic material of the plug bridge may penetrate into the cavity of the plug pin, there is no way to equip waterproof plug with hollow pin contacts. Characterized in that the socket side open cavity according to the WO 03/092123 A1 of the hollow pin is provided with a seal, this problem should be remedied. However, the known technical solution can not prevent water or moisture from penetrating into the interior of the socket-side part of the hollow pin and there causes corrosion, which also put a long-term stability of the plug and thus its usability in outdoor areas, in wet rooms and the like in question can. In addition, no complete roundness or dimensional stability is achieved in cross section by a stamped or stamped bent part as a pin of the known type due to the presence of the longitudinal seam resulting from the production, which can lead to difficulties when plugging.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Steckerbrücke und einen Steckerhohlstift der eingangs genannten Art zu schaffen, mit der bzw. mit dem in technologisch wenig aufwändiger Weise die Funktionalität und Langzeitstabilität eines mit diesen Teilen ausgerüsteten Steckers erhöht werden kann.The present invention has for its object to provide a connector bridge and a plug hollow pin of the type mentioned, with or with the technologically little complex manner, the functionality and long-term stability of a equipped with these parts connector can be increased.

Erfindungsgemäß wird dies dadurch erreicht, dass der Steckerhohlstift als nahtfreier, einseitig offener Hohlzylinder mit anderseitig geschlossener, insbesondere abgerundeter, Einsteckspitze, vorzugsweise zumindest teilweise als Tiefziehteil oder als Fließpressteil gefertigt ist. Hierdurch gelingt es vorteilhafterweise, in technologisch einfacher Weise einen vollkommen nahtfrei ausgebildeten formstabilen Steckerhohlstift herzustellen, der vollständig gegen das Eindringen von Feuchtigkeit und Schmutz geschützt ist.According to the invention this is achieved in that the plug hollow pin is made as a seamless, one-sided open hollow cylinder with other closed, in particular rounded, Einsteckspitze, preferably at least partially as a deep-drawn or extruded part. This makes it possible, advantageously, in a technologically simple manner, a completely seamlessly formed dimensionally stable plug hollow pin which is completely protected against ingress of moisture and dirt.

Das Tiefziehen ist entsprechend der Definition der DIN 8584 ein Zug-Druck-Umformen eines Blechzuschnitts in einen einseitig offenen Hohlkörper oder eines bereits vorgezogenen Hohlkörpers in einen solchen mit geringerem Querschnitt, ohne dass die Blechdicke gewollt verändert wird. Man unterscheidet dabei ein Tiefziehen mit Werkzeugen, ein Tiefziehen mit Wirkmedien, wie Gasen oder Flüssigkeiten, und ein Tiefziehen mit Wirkenergie. Das erstgenannte Verfahren stellt dabei die klassische und weitestverbreitete Variante dar, wobei die zur Umformung notwendige Presskraft mit Hilfe eines Stempels auf den Boden des zu fertigenden Tiefziehteiles über die Bodenrundung und dem Seitenteil (Flansch) in den eigentlichen Umformbereich geleitet wird, der sich zwischen einem Ziehring und einem Niederhalter befindet. Die Umformung erfolgt durch radiale Zugspannung und dadurch bewirkte tangentiale Druckspannungen. Durch die Druckspannungen erfolgt eine Durchmesserreduzierung z. B. bei einer Ronde. Durch die radialen Zugspannungen im Umformbereich wird eine Blechverdickung vermieden. Mit dem Stempel wird der Blechzuschnitt durch den Ziehring gedrückt. Der Niederhalter verhindert die Bildung von Falten am Ziehteil.The deep drawing is according to the definition of DIN 8584 a train-pressure-forming a sheet metal blank in a hollow body open on one side or an already preferred hollow body in such a smaller cross-section, without the sheet thickness is deliberately changed. A distinction is made between deep drawing with tools, deep drawing with active media such as gases or liquids, and deep drawing with active energy. The former method is the classic and most widely used variant, wherein the pressing force necessary for forming is conducted by means of a punch on the bottom of the deep-drawn part to be produced on the bottom rounding and the side part (flange) in the actual forming area, which is located between a draw ring and a hold-down. The forming takes place by radial tensile stress and thereby caused tangential compressive stresses. Due to the compressive stresses a diameter reduction z. B. at a Ronde. Due to the radial tensile stresses in the forming area a plate thickening is avoided. With the stamp, the sheet metal blank is pressed through the drawing ring. The hold-down prevents the formation of wrinkles on the drawn part.

Das Fließpressen ist nach der DIN 8583 ein Druck-Umform-Verfahren, bei dem eine Massivumformung eines Rohlings erfolgt, wobei im Ergebnis durch einen ein- oder mehrstufigen Fertigungsvorgang ein Vollkörper oder - wie erfindungsgemäß vorgesehen - ein Hohlkörper entstehen kann. Dabei wird der Werkstoff unter Einwirkung eines hohen Druckes zum Fließen gebracht. Ein Stempel drückt den Rohling durch eine formgebende, im Querschnitt verminderte, Werkzeugöffnung - eine Matrize. Dieser Umformprozess kann bei Raumtemperatur - in diesem Fall spricht man von Kaltfließpressen - oder nach einer Erwärmung des Rohlings erfolgen, wobei man dann von einem Halbwarmfließpressen oder Warmfließpressen spricht. Zur Fertigung des erfindungsgemäßen Steckerhohlstiftes kann bevorzugt als Kaltfließpressen ein sogenanntes Napfen eingesetzt werden. Hierbei werden eine hohe Maßgenauigkeit sowie Oberflächengüte erreicht.Extrusion is according to DIN 8583 a pressure-forming process in which a massive forming of a blank takes place, as a result of a single or multi-stage manufacturing process, a solid body or - as provided according to the invention - a hollow body can arise. The material is made to flow under the action of a high pressure. A stamp pushes the blank through a shaping, reduced in cross-section, tool opening - a die. This forming process can be carried out at room temperature - in this case one speaks of cold extrusion presses - or after a heating of the blank, which is then referred to as a semi-warm extrusion or hot extrusion. For the production of the plug hollow pin according to the invention, a so-called cupping can be used preferably as cold extrusion. Here, a high dimensional accuracy and surface quality can be achieved.

Die Grundplatte der erfindungsgemäßen Steckerbrücke kann dabei in an sich bekannter Weise gegossen und/oder gespritzt sein, so dass der erfindungsgemäße Steckerhohlstift - bzw. wie bei einem Stecker üblich zwei Steckerhohlstifte - verdreh- und auszugsicher in der Platte befestigbar bzw. befestigt ist/sind.The base plate of the connector bridge according to the invention can be cast and / or sprayed in a conventional manner, so that the plug hollow pin according to the invention - or as in a connector usual two plug hollow pins - twist-proof and secure in the plate fastened or secured / are.

Außer den Steckbereichen 4, die in eine Steckdose einschiebbare Kontakte darstellen, kann ein Stecker bzw. eine Steckerbrücke 2, mit den erfindungsgemäßen Steckerhohlstiften 3 in an sich bekannter Weise auch sogenannte, insbesondere um 90° gegenüber der Ebene der Steckerhohlstifte 3 versetzt liegende Masse-Erdungsbügel aufweisen.In addition to the plug-in areas 4, the insertable into a socket contacts, a plug or a plug bridge 2, with the plug hollow pins 3 according to the invention in a conventional manner also called, in particular offset by 90 ° relative to the plane of the plug hollow pins 3 ground grounding strap exhibit.

Im Anschlussbereich 6 für das Netzkabel erfolgt die Befestigung der abisolierten Litzen des Kabels, wofür beispielsweise ein Vercrimpen, Verlöten oder eine Verschraubung vorgesehen werden kann.In the connection area 6 for the power cord, the attachment of the stripped strands of the cable, for which, for example, crimping, soldering or screwing can be provided.

Der Steckerhohlstift 3 sollte zumindest in seinem steckdosenseitig aus der Grundplatte 2 herausragenden Steckbereich 4 als Tiefziehteil oder als Fließpressteil gefertigt sein.The plug hollow pin 3 should be made at least in its plug socket side protruding from the base plate 2 plug-in area 4 as a deep-drawn or extruded part.

Der Haltebereich 5 und/oder der Anschlussbereich 6 für das Netzkabel kann zusätzlich oder alternativ als Umform- und/oder Prägeteil ausgebildet sein.The holding region 5 and / or the connection region 6 for the power cable can additionally or alternatively be designed as a forming and / or embossing part.

So zeigt die in Fig. 4 und 5 dargestellte Ausführung des erfindungsgemäßen Steckerhohlstiftes 3 einen Haltebereich 5, der bei einer durch Umformung erzeugten konkaven Wölbung 7 einen gegenüber dem Außendurchmesser D4 des Steckbereiches 4 verringerten Außendurchmesser D5 aufweist. Außerdem sind in diesem Haltebereich 5 - insbesondere durch Prägung erzeugte - sickenartige Vertiefungen bzw. mit dem Bezugszeichen 8 gekennzeichnete Rippen vorgesehen. Dadurch wird erreicht, dass die Grundplatte 2 der Steckerbrücke 1 die Steckerhohlstifte 3 in der für die jeweilige elektrische Norm korrekten geometrischen Ausrichtung umschließt, wobei durch einen form- und materialschlüssigen Verbund, in welchem der Steckerhohlstift 3 mit seinem die Grundplatte 2 durchdringenden Haltebereich 5 vom Material der Grundplatte 2 umspritzt bzw. umgossen ist, eine gegenseitige Befestigung erzielt wird, die eine Verdrehung oder Axialverschiebung des erfindungsgemäßen Steckerhohlstiftes 3 sicher verhindert.So shows the in 4 and 5 illustrated embodiment of the plug hollow pin 3 according to the invention a holding portion 5, which has a relation to the outer diameter D4 of the plug-in area 4 reduced outer diameter D5 at a concave curvature 7 generated by deformation. In addition, in this holding region 5 - provided in particular by embossing - bead-like depressions or marked with the reference numeral 8 ribs. This ensures that the base plate 2 of the connector bridge 1 surrounds the plug hollow pins 3 in the correct geometric alignment for the respective electrical standard, in which the plug hollow pin 3 with its the base plate 2 penetrating holding portion 5 of the material by a positive and material-locking composite the base plate 2 is encapsulated or encapsulated, a mutual attachment is achieved, which reliably prevents a rotation or axial displacement of the plug hollow pin 3 according to the invention.

Sowohl für die Grundplatte 2 als auch für den Steckerhohlstift 3 sind verschiedenartige Ausbildungen möglich. So ist der Querschnitt des erfindungsgemäßen Steckerhohlstiftes 3 nicht auf eine kreisrunde Ausbildung beschränkt, sondern könnte auch durch eine rechteckige Form gebildet sein. Für die Grundplatte 2 kann - wie in Fig. 1 bis 3 dargestellt - in vorteilhafter Ausbildung z. B. vorgesehen sein, dass daran insbesondere hakenförmig ausgebildete Ausziehsicherungsteile 9 zur Kabelhalterung ausgebildet oder befestigt sind.Both for the base plate 2 and the plug hollow pin 3 various types are possible. Thus, the cross section of the plug hollow pin 3 according to the invention is not limited to a circular design, but could also be formed by a rectangular shape. For the base plate 2 can - as in Fig. 1 to 3 shown - in an advantageous training z. B. be provided that formed in particular hook-shaped Ausziehsicherungsteile 9 for cable holder or attached.

Der Anschlussbereich 6 des erfindungsgemäßen Steckerhohlstiftes 3 kann in bevorzugter Ausbildung - wie gezeigt - zumindest bereichsweise als Trichter 6a ausgebildet sein, wobei insbesondere ein maximaler Außendurchmesser D6 des Trichters 6a größer ist als ein maximaler Außendurchmesser D4 des Steckbereichs 4 und ein maximaler Außendurchmesser D5 des Haltebereiches 5. Diese Formgestaltung ist insofern von technologischer Bedeutung, als sie es ermöglicht, erfindungsgemäß in einem Blech durch Tiefziehen und nachfolgende Umformung und/oder Prägung erzeugte Steckerhohlstifte 3 im Bereich des Außendurchmessers D6 aus dem Blech auszustanzen. Der Trichter 6a kann als Einführ- und Befestigungshilfe für die anzuschließenden Kabelenden dienen.The connection region 6 of the plug hollow pin 3 according to the invention can, as shown, be embodied at least in regions as a funnel 6a, wherein in particular a maximum outer diameter D6 of the funnel 6a is greater than a maximum outer diameter D4 of the plug region 4 and a maximum outer diameter D5 of the holding region 5 This shape design is of technological importance insofar as it makes it possible, according to the invention, to produce hollow plug pins 3 produced in a metal sheet by deep drawing and subsequent shaping and / or embossing in the region of the outside diameter D6 from the metal sheet punch. The funnel 6a can serve as an insertion and fastening aid for the cable ends to be connected.

In einer weiteren Ausführung der Erfindung kann auch vorgesehen sein, dass der erfindungsgemäße Steckerhohlstift 3 als ein aus zwei Komponenten bestehendes Montageteil ausgebildet ist.In a further embodiment of the invention can also be provided that the male plug pin 3 according to the invention is designed as a two-part mounting part.

Eine solche zweiteilige Ausführung zeigen Fig. 6 und 7. Diese Ausführung unterscheidet sich von der ersten Ausführung durch die Ausbildung des Anschlussbereiches 6. Dieser ist in der zweiten Ausführung der Erfindung als Steckerteil, insbesondere als Flachstecker 6b, ausgebildet, der die zweite Komponente des Montageteils bildet, während der Steckbereich 4 und der Haltebereich 5 die erste Komponente bilden. Der Flachstecker 6b weist dabei einen im Wesentlichen in Richtung der Längsachse X-X des Streckerhohlstiftes 3 verlaufenden Steckabschnitt 61 und einen rechtwinklig dazu abgebogenen Befestigungsabschnitt 62 auf. Der Befestigungsabschnitt 62 ist mit dem Haltebereich 5 des Steckerhohlstiftes 3 verbördelt, wobei der Haltebereich 5 mit einem durchmesserverengten Abschnitt 51 eine im Befestigungsabschnitt 62 befindliche Öffnung 63 durchgreift, über der ein Bördelrand 52 gebildet ist.Such a two-part design show 6 and 7 , This embodiment differs from the first embodiment in that the connection region 6 is formed. In the second embodiment of the invention, the latter is designed as a plug part, in particular as a flat plug 6b, which forms the second component of the mounting part, while the plug-in region 4 and the holding region 5 form the first component. In this case, the tab 6b has a plug-in section 61 running substantially in the direction of the longitudinal axis XX of the straightener hollow pin 3 and a fastening section 62 bent at right angles thereto. The mounting portion 62 is crimped with the holding portion 5 of the plug hollow pin 3, wherein the holding portion 5 engages with a diameter-narrowed portion 51 located in an attachment portion 62 opening 63, over which a bead 52 is formed.

Die für die Durchmesser der einzelnen axial (Längsachse X-X) hintereinander liegenden Bereiche des erfindungsgemäßen Steckerhohlstiftes - Steckbereich 4, Haltebereich 5, Anschlussbereich 6 - beschriebenen geometrischen Relationen sind dann entsprechend auf die z. B. rechteckigen Außenkonturen der Bereiche zu übertragen. Der Anschluss des Anschlussbereichs 6 kann auf eine Klemme, eine Feder oder mittels eines Gewindes erfolgen, ohne dass der Rahmen der Erfindung verlassen wird.As already apparent from the foregoing, the present invention is not limited to the illustrated embodiment, but includes all means and measures in the sense of the invention equally effective. So it falls for example - as mentioned - also within the scope of the invention, when the plug hollow pin is not round. The term hollow cylinder therefore also includes according to the invention a design as a hollow prism. The for the diameter of each axial (longitudinal axis X-X) successive areas of the plug hollow pin according to the invention - plug-in area 4, holding area 5, terminal area 6 - described geometric relations are then corresponding to the z. B. rectangular outer contours of the areas to transfer. The connection of the connection region 6 can be made on a clamp, a spring or by means of a thread without departing from the scope of the invention.

Ferner ist die Erfindung nicht auf die in den unabhängigen Ansprüchen definierten Merkmalskombinationen beschränkt, sondern kann auch durch jede beliebige andere Kombination von bestimmten Merkmalen aller insgesamt offenbarten Einzelmerkmale definiert sein. Dies bedeutet, dass grundsätzlich praktisch jedes Einzelmerkmal der unabhängigen Ansprüche weggelassen bzw. durch mindestens ein an anderer Stelle der Anmeldung offenbartes Einzelmerkmal ersetzt werden kann. Insofern sind die Ansprüche lediglich als ein erster Formulierungsversuch für eine Erfindung zu verstehen.Further, the invention is not limited to the feature combinations defined in the independent claims, but may be limited by any other Be defined as a combination of certain features of all the individual features disclosed.
