Abstract

In the case of an injection-moulded German standard mains plug for electrical devices which can be connected to a mains plug socket, having an essentially U-shaped plug bridge for holding an earthing spring with a hollow cylindrical connection bush for the protective earth conductor of a load cable, with an insertion funnel having a conical throughbore being assigned to this connection bush, this insertion funnel is formed on an L-shaped moulding (21) which projects from the planar base plate of the plug bridge (1) and projects over the connection bush (19). This produces a plug bridge which is optimised with regard to production technology insofar as the cooling times are reduced by the lower material requirements for the moulding. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen Schutz­ kontaktstecker nach dem Oberbegriff des Patentanspruchs. Ein Schutzkontaktstecker dieser Art ist Gegenstand des Patents ... (Patentanmeldung P 38 07 716.7-34).The present invention relates to protection Contact plug according to the preamble of the claim. A protective contact plug of this type is the subject of the patent ... (patent application P 38 07 716.7-34).

Auch wenn sich dieser Stecker bereits außerordentlich gut bewährt und weitgehend durchgesetzt hat, so hat es sich doch gezeigt, daß noch Verbesserungen möglich sind, und zwar im Hinblick auf die sogenannte Einführ­ hilfe für den Schutzleiteranschluß der Verbraucher­ leitung. Bei der konstruktiven Lösung nach dem Haupt­ patent (Patentanmeldung P 38 07 716.7-34) besteht diese Einführhilfe von der Prinziplösung her aus einem sepa­ ratem Formteil, das auf der Anschlußbuchse für den Schutzleiter aufliegt; die im Hauptpatent (Patentan­ meldung P 38 07 716.7-34) offenbarte konkrete Lösung besteht darin, daß der Einführtrichter direkt am ent­ sprechenden Steg der Steckerbrücke angeformt ist, und so der Anschlußbuchse für den Schutzleiter gegenüber liegt.Even if this connector is already extraordinary has proven itself well and has largely been implemented it has been shown that improvements are still possible are, with regard to the so-called introductory help for the protective conductor connection of the consumers management. At a constructive solution on the head patent (patent application P 38 07 716.7-34) this exists Introductory aid based on the principle solution from a sepa ratem molded part, which on the connection socket for the Protective conductor rests; those in the main patent (Patentan message P 38 07 716.7-34) disclosed concrete solution is that the insertion funnel directly on the ent speaking bridge of the plug bridge is formed, and so the connection socket for the protective conductor opposite lies.

Mit der vorliegenden Erfindung soll ein weiterer Weg zur Realisierung des Einführtrichters für den Schutz­ leiter aufgezeigt werden. Another way is intended with the present invention to implement the insertion funnel for protection heads are shown.  

Dieser erfindungsgemäße Einführtrichter ist dadurch charakterisiert, daß er an einem von der ebenen Grund­ platte der Steckerbrücke 1 abstehenden separaten Form­ teil integriert ist.This insertion funnel according to the invention is characterized in that it is integrated in part on a plate protruding from the flat base of the connector bridge 1 .

Diese Lösung hat insofern fertigungstechnische Vorzüge, als die Abkühlzeiten für die Steckerbrücke und damit die Gefahr des Verzugs dieser Steckerbrücke aufgrund Materialschwunds vermindert sind.This solution has manufacturing advantages, than the cooling times for the jumper and thus the risk of warping this jumper due to Material shrinkage are reduced.

Die Erfindung wird im folgenden anhand der Zeichnung naher erläutert. Diese zeigtThe invention is described below with reference to the drawing explained in more detail. This shows

  • - zwei Ansichten eines Schutzkontaktsteckers in Schnittdarstellung mit einem von der Grundplatte der Steckerbrücke abstehenden L-förmigen Form­ teil.- Two views of a safety plug in Sectional view with one of the base plate protruding L-shaped shape part.

Die Steckerbrücke 1 nach Fig. 1 besteht im wesentlichen aus einem U-förmigen Formteil 10 aus hartelastischem Kunststoff. Die beiden Schenkel 11, 12 des U begrenzen einen Freiraum 13 und sind über einen Verbindungssteg 14 (Grundplatte der Steckerbrücke 1) miteinander ver­ bunden.The bridge plug 1 according to Fig. 1 consists essentially of a U-shaped molding 10 of hard-elastic plastic. The two legs 11 , 12 of the U delimit a free space 13 and are connected to each other via a connecting web 14 (base plate of the plug bridge 1 ).

Die soweit bezüglich der mechanischen Grundform be­ schriebene Steckerbrücke 1 ist elektrisch wie folgt bestückt: An der Außenseite der Grundplatte 14 ragen in genormten Abstand zueinander und mit genormter Länge Kontaktstifte 15 nach außen (mit denen der Stecker letztlich in eine Netzsteckdose eingeführt wird). Die Kontaktstifte 15 sitzen fest in ensprechenden Bohrungen der Grundplatte 14 und sie sind (am zweiten Ende) rück­ seitig soweit verlängert, daß sie in Form von hohl­ zylindrischen Anschlußstiften 16 in den Freiraum 13 des U-förmigen Formteils 10 ragen. Mit diesen Anschluß­ stiften 16 werden letztlich die Stromleiter einer Ver­ braucherleitung mechanisch verbunden, insbesondere angecrimpt oder angequetscht.The plug bridge 1 described so far with regard to the basic mechanical shape is electrically equipped as follows: on the outside of the base plate 14, at a standardized distance from one another and with a standardized length, contact pins 15 project outwards (with which the plug is ultimately inserted into a mains socket). The contact pins 15 are firmly seated in corresponding holes in the base plate 14 and they are (at the second end) extended to the rear so far that they protrude in the form of hollow cylindrical connecting pins 16 into the free space 13 of the U-shaped molded part 10 . With this connection pins 16 are ultimately the conductor of a United consumer line mechanically connected, in particular crimped or crimped.

Das elektrische System wird durch einen Schutzleiter vervollständigt, der als Teil der Verbraucherleitung mit einer Anschlußbuchse 19 verbunden ist. Die Anschluß­ buchse 19 des Schutzleiters ist Teil einer an den Außen­ seiten der Schenkel 11, 12 des U-förmigen Formteils 10 liegenden Erdungsfeder 20, die beim Einstecken des Schutzkontaktsteckers in eine Netzsteckdose diese mit einer sich im anzuschließenden Gerät befindlichen Kupp­ lung verbindet, so daß der Schutzleiter der Verbraucher­ leitung und damit das Gerät selbst Erdschluß haben.The electrical system is completed by a protective conductor, which is connected to a connecting socket 19 as part of the consumer line. The connection socket 19 of the protective conductor is part of a lying on the outer sides of the legs 11 , 12 of the U-shaped molded part 10 grounding spring 20 , which connects this with a plug located in the device to be connected when connecting the protective contact plug into a device, so that the protective conductor of the consumer line and thus the device itself have a ground fault.

Die soweit beschriebene Steckerbrücke 1 ist Stand der Technik. Beim Umspritzen dieser Steckerbrücke zwecks Endfertigung des Schutzkontaktsteckers können nun Pro­ bleme dahingehend auftreten, daß es bei seitlich ab­ stehenden Einzeldrähtchen der Stromleiter und des Schutzleiters vorkommen kann, daß diese bis nach außen durch den gespritzten Steckerkopf reichen und somit eine Gefahrenquelle bilden.The plug bridge 1 described so far is state of the art. When encapsulating this jumper for the purpose of finishing the protective contact plug, problems can now occur that it can occur with individual wires standing laterally from the current conductor and the protective conductor that these extend outwards through the molded plug head and thus form a source of danger.

Um dieses Risiko gänzlich auszuschalten und sicher zu gewährleisten, daß die Einzeldrähtchen sicher einge­ fangen werden, ist die Steckerbrücke 1 mit der Erdungs­ feder 20 dem Hauptpatent (Patentanmeldung P 38 07 716.7- 34) gemäß so ausgebildet, daß den Anschlußstiften 16 und der Anschlußbuchse 19 eine konische Einführhilfe für die Leiterenden der Stromleiter und des Schutz­ leiters vorgesetzt ist. Gemäß der vorliegenden Weiter­ bildung ist diese Einführhilfe für den Schutzleiter wie folgt verifiziert: Dem der Anschlußbuchse 19 für den Schutzleiter benach­ barten Schenkel 11 des U ist - als integrierter Bestand­ teil der Spritzform für die Grundplatte der Stecker­ brücke 1 - ein von dieser Grundplatte 1 abstehendes L-förmiges Formteil 21 angespritzt. Dieses Formteil 21 steht parallel zu den Schenkeln 11, 12 des U-förmigen Formteils 10 und ragt über die Anschlußbuchse 19 hinaus; das Formteil 21 stützt sich also über einen von einem L-Schenkel gebildeten Stützfuß 22 an der Grundplatte 14 der Steckerbrücke 1 ab.In order to completely eliminate this risk and to ensure that the individual wires are safely caught, the connector bridge 1 with the grounding spring 20 is designed according to the main patent (patent application P 38 07 716.7- 34) in such a way that the connecting pins 16 and the connecting socket 19 a conical insertion aid for the conductor ends of the current conductor and the protective conductor is provided. According to the present training, this insertion aid for the protective conductor is verified as follows: The connecting socket 19 for the protective conductor adjacent leg 11 of the U is - as an integral part of the injection mold for the base plate of the connector bridge 1 - a protruding from this base plate 1 L-shaped molding 21 molded. This molded part 21 is parallel to the legs 11 , 12 of the U-shaped molded part 10 and projects beyond the connecting socket 19 ; the molded part 21 is thus supported on the base plate 14 of the connector bridge 1 by a support leg 22 formed by an L-leg.

Am freien Ende ist der den Stützfuß 22 bildende L-Schenkel rechtwinklig so abgekröpft, daß sich eine zum benachbarten Schenkel 11 hin gerichtete Überdachung 23 für die Anschlußbuchse 19 des Schutzleiters ergibt. Diese Überdachung 23 wird letztlich vom kurzen Schenkel des L-förmigen Formteils 21 gebildet.At the free end of the L-leg forming the support leg 22 is bent at right angles so that there is a canopy 23 facing the adjacent leg 11 for the connecting socket 19 of the protective conductor. This canopy 23 is ultimately formed by the short leg of the L-shaped molded part 21 .

Ein wesentliches Teilmerkmal des L-förmigen Formteils 21 ist eine koaxial zur zugehörigen Anschlußbuchse 19 liegende konische Durchgangsbohrung 24, deren kleinerer Durchmesser der Stirnseite der Anschlußbuchse 19 gegen­ überliegt. So ergibt sich zur freien Seite des L-förmigen Formteils 21 hin eine trichterförmige Erweiterung, über die sich das abisolierte Leitungsende des Schutz­ leiters leicht und sicher in die Anschlußbuchse 19 ein­ führen läßt. An essential partial feature of the L-shaped molded part 21 is a conical through bore 24 lying coaxially with the associated connection socket 19 , the smaller diameter of which lies opposite the end face of the connection socket 19 . This results in a funnel-shaped extension to the free side of the L-shaped molded part 21 , through which the stripped line end of the protective conductor can be easily and safely guided into the connecting socket 19 .

Für den Fall, daß wider Erwarten doch einmal ein Einzel­ drähtchen des Schutzleiters abknicken und abstehen sollte, ist die Materialstärke des L-förmigen Formteils 21 im Bereich der Durchgangsbohrung 24 so gewählt, daß - der Länge der Abisolierung entsprechend - dieses Einzeldrähtchen sicher hinter der Oberkante der Durch­ gangsbohrung 24 verschwindet.In the event that, contrary to expectations, a single wire of the protective conductor should bend and protrude, the material thickness of the L-shaped molded part 21 in the area of the through hole 24 is selected so that - corresponding to the length of the stripping - this individual wire is safely behind the upper edge the through hole 24 disappears.

Der Schutzleiter läßt sich somit sicher mit Hilfe des L-förmigen Formteils 21 bzw. der konischen Durchgangs­ bohrung 24 einführen und fixieren, beispielsweise durch quetschen bzw. crimpen.The protective conductor can thus be safely inserted and fixed using the L-shaped molded part 21 or the conical through hole 24 , for example by squeezing or crimping.
