The webs (22) are connected to one another on their free side by means of a covering plate (20) located parallel to the retaining plate (12), in which covering plate (20) there is provided a conical perforating hole (21) coaxially with respect to each of the connecting pins (11). In consequence, the production of the plugs can be simplified and the electrical safety can be improved at the same time. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen elektri­schen Gerätestecker nach dem Oberbegriff des Patentan­spruchs 1.The present invention relates to an electrical connector according to the preamble of patent claim 1.

Derartige Stecker sind bekannt; sie dienen dazu, ein elektrisches Gerät mit einer Netzsteckdose und damit mit dem Energieversorgungssystem des Elektrizitätswerks zu verbinden. Das entsprechende Verbindungskabel, d. h. die Verbraucherleitung, wird dazu über einen Schutzkon­taktstecker mit der Netzsteckdose und über einen gat­tungsgemäßen Gerätestecker mit dem Gerät selbst gekop­pelt.Such plugs are known; they are used to connect an electrical device to a mains socket and thus to the power supply system of the power plant. The corresponding connection cable, i.e. H. the consumer line is coupled to the mains socket via a protective contact plug and to the device itself via a generic device plug.

Diese Gerätestecker werden heute weitgehend automatisiert hergestellt. Dabei werden die Stromleiter und der Schutz­leiter der Versorgungsleitung, d. h. des Verbindungska­bels je in eine Kontaktfeder eingeführt und mittels einer Quetsch-/Crimp-Verbindung fest verbunden.These device plugs are now largely automated. The current conductor and the protective conductor of the supply line, i.e. H. of the connecting cable inserted into a contact spring and firmly connected by means of a crimp / crimp connection.

Beim Einführen der Leiter in die zugehörigen Kontaktfe­dern besteht die Gefahr, daß einzelne Leiterdrähtchen an der Stirnseite der Kontaktfeder anstoßen und abknicken. Wird dies nicht bemerkt, so kann es vorkommen, daß beim abschließenden Umspritzen der Kontaktfedern mit den ein­geführten Leiterenden die abgeknickten abstehenden Ein­zeldrähtchen durch die Oberfläche des Gerätesteckers ra­gen oder so nahe zur Außenseite hin liegen, daß bei der Handhabung des Gerätesteckers ein Erdschluß entstehen kann. Die Person, die den Gerätestecker in die Gegen­steckdose des anzuschließenden Geräts steckt, kann da­durch einen gesundheitlichen Schaden erleiden, der so­gar zum Tod führen kann.When inserting the conductors into the associated contact springs, there is a risk that individual conductor wires will bump and kink on the end face of the contact spring. If this is not noticed, it may happen that when the contact springs are finally encapsulated with the inserted conductor ends, the bent individual wires protrude through the surface of the connector or are so close to the outside that the Handling the device plug can cause an earth fault. The person who plugs the device plug into the mating socket of the device to be connected can suffer health damage that can even lead to death.

Aus diesem Grunde werden die fertigen, d. h. fertig ge­spritzten Gerätestecker jeweils einzeln mittels soge­nannter Konturenprüfeinrichtungen auf ihre elektrische Sicherheit geprüft. Der Stecker wird dazu in eine der Form entsprechende Prüfform eingelegt und von außen elektrisch beaufschlagt. Auf diese Weise können Stek­ker mit nach außen durchstehenden oder einen zu gerin­gen Abstand aufweisenden Einzeldrähten eliminiert wer­den. Diese ist jedoch mit erheblichen Produktions, d. h. Prüfkosten verbunden.For this reason, the finished, i.e. H. Completely injected device plugs are individually checked for their electrical safety using so-called contour testing devices. For this purpose, the plug is inserted into a test form that corresponds to the shape and electrically charged from outside. In this way, connectors with individual wires that protrude outwards or are too close apart can be eliminated. However, this is with significant production, i.e. H. Associated testing costs.

Die der vorliegenden Erfindung zugrunde liegende Aufga­be besteht darin, einen Gerätestecker der gattungsge­mäßen Art anzugeben, bei dem die vorgenannten Gefahren auf Grund beim Einführen der Leiter abgeknickter und somit ggf. seitlich abstehender Einzeldrähtchen von vornherein vermieden sind.The object on which the present invention is based is to specify a device plug of the generic type, in which the aforementioned dangers due to kinking of the conductor when inserting the conductor and thus possibly protruding laterally individual wires are avoided from the outset.

Diese Aufgabe wird durch das im kennzeichnenden Teil des Patentanspruch 1 angegebene, aus der Halteplatte und der Deckplatte bestehende Formteil gelöst, wobei ergänzend darauf hingewiesen wird, daß mittels dieses Formteils die Fertigungszeiten, d. h. die Produktions­zyklen, wegen der als Einführhilfe für die abisolier­ten Leiterenden dienenden konischen Durchgangslöcher ganz wesentlich verkürzt werden konnten. Die erfin­dungsgemäße Lösung hat somit einen erheblichen wirt­schaftlichen Erfolg gebracht.This object is achieved by the molded part consisting of the holding plate and the cover plate specified in the characterizing part of patent claim 1, it being additionally pointed out that by means of this molded part the manufacturing times, ie the production cycles, because of the conical serving as an insertion aid for the stripped conductor ends Through holes could be shortened significantly. The solution according to the invention has thus brought considerable economic success.

Weiterbildungen bzw. besondere Ausgestaltungen des er­findungsgemäßen Gerätesteckers sind Gegenstand der Un­teransprüche.Further developments or special configurations of the device plug according to the invention are the subject of the dependent claims.

Die Einzelheiten dieses Gerätesteckers werden im fol­genden anhand eines in der Zeichnung dargestellten Aus­führungsbeispiels näher erläutert.

  • Fig. 1 zeigt einen kompletten Gerätestecker;
  • Fig. 2 zeigt das aus der Halteplatte und der Deckplatte bestehende Formteil.
The details of this connector are explained below with reference to an embodiment shown in the drawing.
  • Fig. 1 shows a complete connector;
  • Fig. 2 shows the molded part consisting of the holding plate and the cover plate.

Der Gerätestecker 1 nach Fig. 1 besteht aus einem 2-­teiligen Isolierstoffgehäuse, und zwar aus einem inela­stischen Formteil 2 und einem elastischen, zum Teil überlappend aufgespritzten Steckerteil 3 (das in der Zeichnung durchsichtig dargestellt ist). Mit dem inela­stischen Formteil 2 wird der Gerätestecker 1 in die Gegensteckvorrichtung eines anzuschließenden elektri­schen Geräts gesteckt; das Steckerteil 3 nimmt eine Versorgungsleitung 4 auf, deren zweites Ende im all­gemeinen mit einem Schutzkontaktstecker verbunden ist, der dann in die Netzsteckdose einzuführen ist.The device plug 1 according to FIG. 1 consists of a two-part insulating material housing, namely an inelastic molded part 2 and an elastic, partly overlapping sprayed-on plug part 3 (which is shown transparently in the drawing). With the inelastic molded part 2, the connector 1 is inserted into the mating connector of an electrical device to be connected; the plug part 3 receives a supply line 4, the second end of which is generally connected to a protective plug which is then to be inserted into the mains socket.

Das inelastische Formteil 2 besteht aus einem Kopf­teil 5 , das letztlich als Griffteil zur Handhabung des Gerätesteckers 1 dient, und einem Kragenteil 6, über das der elastische Steckerteil 3 auf- bzw. ange­spritzt ist. Kopfteil 5 und Kragenteil 6 sind durch einen umlaufenden Wulst 7 gegeneinander abgesetzt. Der Kragenteil 6 weist umlaufende Vorsprünge 8 auf, die eine innige Verbindung zwischen dem Steckerteil 3 und dem Formteil 2 und damit die Zugsicherheit zwi­schen diesen Teilen gewährleisten.The inelastic molded part 2 consists of a head part 5, which ultimately serves as a handle part for handling the device plug 1, and a collar part 6, via which the elastic plug part 3 is injected or molded. The head part 5 and collar part 6 are offset against each other by a circumferential bead 7. The collar part 6 has circumferential projections 8, which ensure an intimate connection between the plug part 3 and the molded part 2 and thus the tensile strength between these parts.

Im Inneren des Formteils 2 sind sogenannte Federkam­mern 9 vorgesehen, in die etwa U-förmige Kontaktfe­dern 10 eingesetzt bzw. eingeschoben sind. Über diese Kontaktfedern 10 wird der Gerätestecker 1 auf die Gegensteckvorrichtung eines elektrischen Geräts gesteckt und die Kontaktfedern 10 greifen dabei federnd und reibschlüssig haltend über die Kontaktstifte der Gegen­steckvorrichtung.So-called spring chambers 9 are provided in the interior of the molded part 2, into which approximately U-shaped contact springs 10 are inserted or inserted. Via these contact springs 10, the connector 1 is plugged into the mating connector of an electrical device and the contact springs 10 grip resiliently and frictionally over the contact pins of the mating connector.

Die Kontaktfedern 10 reichen einerseits bis nahe an die erste Stirnseite des Formteils 2; andererseits stehen sie über die vom Steckerteil 3 überdeckte zwei­te Stirnseite hinaus und bilden hier Anschlußstifte 11 für die Leitungsanschlüsse der Versorgungsleitung 4 (vgl. Bezugszeichen 17).The contact springs 10 extend on the one hand close to the first end face of the molded part 2; on the other hand, they protrude beyond the second end face covered by the plug part 3 and here form connecting pins 11 for the line connections of the supply line 4 (cf. reference number 17).

Die Kontaktfeder 10 stecken in einer Halteplatte 12, die über einen Ansatz 13 und eine komplementäre Hin­terschneidung 14 am Formteil 2 in der zweiten Stirn­seite formschlüssig an- bzw. in die zweite Stirnseite eingesetzt wird. Aus der geschnittenen Seitenansicht in Fig. 1 ist dieser Überlappungsbereich deutlich zu sehen. In diesem Überlappungsbereich können zusätzlich zueinan­der komplementäre Rastmittel vorgesehen werden, um einen zusätzlichen Kraftschluß zwischen dem Formteil 2 und der Halteplatte 12 zu realisieren.The contact spring 10 is inserted in a holding plate 12, which is inserted in a form-fitting manner in the second end face via a shoulder 13 and a complementary undercut 14 on the molded part 2 or inserted into the second end face. This overlap area can be clearly seen from the sectional side view in FIG. 1. In this overlap area complementary locking means can be provided in addition to realize an additional frictional connection between the molded part 2 and the holding plate 12.

Zur Aufnahme und Halterung der Kontaktfedern 10 in der Halteplatte 12 ist diese mit der Form der Kontaktfe­dern 10 entsprechenden Einschnitten versehen. Die Kon­taktfedern 10 werden soweit in diese Einschnitte ein­geschoben, wie es ihrer Soll-Lage im fertigen Geräte­stecker 1 entspricht.To receive and hold the contact springs 10 in the holding plate 12, this is provided with incisions corresponding to the shape of the contact springs 10. The contact springs 10 are inserted into these incisions to the extent that they correspond to their desired position in the finished connector 1.

Der soweit beschriebene Gerätestecker ist Gegenstand des DBGM 87 15 003 und insofern Stand der Technik.The connector described so far is the subject of DBGM 87 15 003 and is therefore state of the art.

Gemäß der vorliegenden Erfindung ist die genannte und bekannte Halteplatte 12 dahingehend weitergebildet, daß sie die Anschlußstifte 11 käfigartig umgibt, wo­bei diese Halteplatte 12 mit einer parallel zu ihr angeordneten Deckplatte 20 verbunden ist, und zwar in einem solchen Abstand, daß diese Deckplatte 20 an den Anschlußstiften 11 an- bzw. aufsteht. Diese Deck­platte 20 ist darüberhinaus mit koaxial zu den über­deckten Anschlußstiften 11 vorgesehenen konischen Durchgangslöchern 21 ausgestatten, die beim Komplet­tieren des Gerätesteckers 1 , d. h. beim Einführen der abisolierten Leiterenden für diese als Einführhil­fe dienen. Über die trichterförmigen Durchgangslöcher 21 können die Leiterenden problemlos und sicher, und darüberhinaus in kurzen Maschinentaktzeiten in die An­schlußstifte 11 eingeschoben werden.According to the present invention, said and known holding plate 12 is further developed in such a way that it surrounds the connecting pins 11 in a cage-like manner, this holding plate 12 being connected to a cover plate 20 arranged parallel to it, and at such a distance that this cover plate 20 is connected to the Pins 11 on or stands up. This cover plate 20 is also equipped with coaxial to the covered pins 11 provided conical through holes 21, which when completing the connector 1, d. H. when inserting the stripped conductor ends serve as an insertion aid. About the funnel-shaped through holes 21, the conductor ends can be easily and safely, and moreover in short machine cycle times inserted into the pins 11.

Konstruktiv betrachtet bedeutet dies, daß die Halte­platte 12 und die Deckplatte 20 zwei kongruent zu­einander ausgebildet, parallel zueinander liegende Formteile sind, die über seitliche Stege 22 starr miteinander verbunden sind, d. h. ein einstückiges kä­figartiges Formteil 30 bilden. Die Länge der Stege 22 entspricht - wie bereits erwähnt - der über die Halteplatte 12 überstehenden Länge der Anschlußstifte 11. Zwischen den Stegen 22 ist das genannte käfigar­tige Formteil 30 offen, so daß nach dem Einführen der Leiterenden in die Anschlußstifte 11 diese miteinan­der verbunden, beispielsweise verquetscht (vercrimpt) werden können.From a design point of view, this means that the holding plate 12 and the cover plate 20 are two congruently formed, mutually parallel molded parts which are rigidly connected to one another via lateral webs 22, i. H. form a one-piece cage-like molded part 30. The length of the webs 22 corresponds - as already mentioned - to the length of the connecting pins 11 projecting beyond the holding plate 12. The cage-like molded part 30 is open between the webs 22, so that after the conductor ends have been inserted into the connecting pins 11, they are connected to one another, for example can be crimped.

Die Materialstärke der Deckplatte 20 ist so gewählt, daß für den Fall, daß wider Erwarten sich beim Einführen der abisolierten Leiterenden doch ein Einzeldrähtchen umlegen sollte, dieses sicher hinter der Oberkante des entsprechenden Durchgangslochs 21 verschwindet, also nicht vorstehen kann.The material thickness of the cover plate 20 is selected so that in the event that, contrary to expectations, a single wire should turn over when the stripped conductor ends are inserted, this is safely behind the upper edge of the corresponding through hole 21 disappears, that is, cannot protrude.

Anhand der Konstruktionszeichnung gemäß Fig. 2 soll das aus der Halteplatte 12 und der Deckplatte 20 beste­hende käfigartige Formteil 30 nochmals für sich allein erläutert werden.2, the cage-like molded part 30 consisting of the holding plate 12 and the cover plate 20 will be explained again for itself.

Die Halteplatte 12 selbst weist den genannten Ansatz 13 auf, über den eine formschlüssige Verbindung zum in­elastischen Formteil 2 hin erreicht wird. Seitlich hat die Halteplatte 12 -und zwar an zwei einander gegen­überliegenden Seiten - eine Paar Stege 22, die an ihren freien Enden wiederum über die Deckplatte 20 miteinan­der verbunden sind. In dieser Deckplatte 20 sind die konischen Durchgangslöcher 21 integriert, und zwar so, daß entweder koaxial zur Position der Anschlußstifte 11 kreisringförmige Vorsprünge 24 mit den Durchgangslöchern 21 vorgesehen sind - vgl. die zeichnerische Darstellung - oder daß die Deckplatte 20 selbst so dick gewählt wird, daß die Durchgangslöcher 21 tief genug sind, etwa doch umgebogene Einzeldrähtchen einzufangen. Wesentlich bezgl. der Durchgangslöcher ist, daß derartige - wider Erwarten - umgebogene Einzeldrähtchen sicher hinter der Vorderkante der Durchgangslöcher verschwinden.The holding plate 12 itself has the mentioned approach 13, via which a positive connection to the inelastic molded part 2 is achieved. On the side, the holding plate 12 has a pair of webs 22, namely on two opposite sides, which are in turn connected to one another at their free ends via the cover plate 20. In this cover plate 20, the conical through holes 21 are integrated, in such a way that either annular projections 24 with the through holes 21 are provided coaxially with the position of the connecting pins 11 - cf. the graphic representation - or that the cover plate 20 itself is chosen so thick that the through holes 21 are deep enough to capture bent individual wires. It is essential with regard to the through holes that such - contrary to expectations - bent individual wires securely disappear behind the front edge of the through holes.
