Definitions
- the present invention relates to a safety plug for electrical devices that can be connected to a mains socket.
- Plugs of this type are known from EP-A-0 391 298 and FR-A-2 538 625, which belong to the state of the art under Article 54 (3) EPC and on the whole have also proven themselves.
- such protective contact plugs have the task of handling an electrical device, i.e. the connection of this device when plugging the connector into the power outlet does not become a danger that people may be at risk due to a so-called earth fault.
- the manufacture and design of the safety plug are subject to strict requirements and regulations. In modern, especially automated mass production, special attention should be paid to ensuring that the conductor connections, i.e. the current conductors and the protective conductors, which are connected to the plug and which establish the electrical connection between the power plant on the one hand and the device on the other hand, provide a sufficient safety distance Outside of the safety plug. Finally, there is a risk that individual wires of the conductor during manufacture when inserted into the bores of the hollow cylindrical connecting pins or Bend and tilt the connection sockets so that they protrude outwards from the finished plug. If this is not noticed, it can happen that the possibly protruding individual wires protrude through the surface of the molded injection plug or are so close to the outside that an earth fault occurs during handling.
- the person who plugs the plug into the socket can suffer health damage that can even lead to death.
- the finished earthing contact plugs are individually checked for their electrical safety using so-called contour testing devices.
- the plug is inserted into a test form corresponding to its shape and electrically charged from the outside.
- plugs with individual wires that stand outwards or are too close apart can be eliminated.
- this is associated with significant production costs, i.e. Testing costs.
- the known plugs only partially solve the problems mentioned. Although they have funnel-shaped insertion aids, which are incorporated into L-shaped molded parts, individual wires of the strands to be inserted are kinked, rolled up or otherwise bent if the insertion funnel is missed during assembly. The reason for this lies in the shape and arrangement of the horizontal section of the L-shaped molded part.
- the insertion funnel is sunk in a flat plate or as a tube with an inner cone on a flat plate. In both cases, the unthreaded wires hit the flat surface next to the insertion funnel almost vertically in order to be deformed there. These rolled up and kinked wires jam with the strand insulation during further insertion in the corresponding insertion funnel. In many cases, the insertion is terminated prematurely. As a result, the unthreaded wires continue to protrude and the crimping is not secure.
- the plug bridge 1 consists of a substantially flat, approximately diamond-shaped (see top view) base plate 20 made of hard-elastic plastic, and a grounding spring 30 which is positively and non-positively clamped on two diametrically opposite connection sides of the diamond sides of the base plate 20 which abut one another (see reference number 31 ) and runs across the underside 21 of the base plate 20 (see reference numeral 32).
- the earthing spring 30 protrudes on both sides over the upper side 22 of the base plate 20, in such a way - see basic view - that vertically protruding legs 33, 34 result, between which a free space 11 is defined on the upper side 22 of the base plate 20.
- One leg 33 of the earthing spring 30 forms a flat side web for said free space 11; the second leg 34 of the grounding spring 30 is formed and deformed so that a connection socket 35 is formed for the protective conductor connection.
- the transverse clasp 32 of the earthing spring 30 has a tab 36 which, when the earthing spring 30 is installed, engages through a corresponding slot in the base plate 20 and is bent (see supervision).
- the jumper 1 described so far is equipped electrically as follows:
- the base plate 20 protrude at a standardized distance from one another and with a standardized length contact pins 40, 41 with which the plug is ultimately inserted into a mains socket.
- the contact pins 40, 41 are seated in corresponding holes in the base plate 20 and they are (at the second end) extended to the rear so far that they protrude in the form of hollow cylindrical connecting pins 42, 43 into the interior of the space 11 between the legs 33, 34 of the grounding spring 30 .
- the current conductors of a consumer line are mechanically connected, in particular clamped or crimped, with these connecting pins 42, 43.
- the electrical system is ultimately formed by the protective conductor connected to the connecting socket 35 of the earthing spring 30 and the current conductor connected to the connecting pins 42, 43 of the contact pins 40, 41.
- the pins 42, 43 of the current conductor and the connecting socket 35 for the protective conductor are arranged approximately in a triangle with respect to one another, the connecting line of the connecting pins 42, 43 being directed perpendicular to the axis of the transverse web 32 of the earthing spring 30.
- the plug bridge 1 described so far is state of the art.
- the problems mentioned at the outset can occur, i.e. in the case of individual wires protruding from the side, it can happen that these extend outwards to, possibly even through the sprayed plug head.
- the plug bridge 1 is designed and / or developed as explained and described below.
- An L-shaped molded part 50 projecting over this connecting socket 35 is injection-molded onto the connecting socket 35 for the protective conductor, preferably as an integral part of the injection mold for the base plate 20.
- This molded part 50 protrudes beyond the connector socket 35 and forms together with a support foot 51 together with the base plate 20 an integral mounting base.
- connection socket 35 for the protective conductor is thus completely bridged, the head part 52 which is kinked at the free front edge by the L-leg of the molded part 50 lying opposite this connection socket 35.
- An essential feature of the head part 52 of the molded part 50 is a conical through hole which is aligned coaxially with the connecting socket 35 for the protective conductor is. The small diameter of this through hole lies opposite the end face of the connecting socket 35, so that it merges into a funnel-shaped extension toward the free side of the head part 52 of the shaped part 50.
- the stripped cable end of the protective conductor can be inserted easily and safely via this funnel-shaped extension and without a single wire of the protective conductor being bent.
- the material thickness of the head part 52 is selected at least so that - depending on the length of the insulation stripped from the protective conductor - this single wire is securely behind the upper edge of the through hole and thus the head part 52 disappears.
- the protective conductor can thus be securely inserted and fixed with the aid of the molded part 50 or the conical through hole, for example by squeezing (crimping).

Abstract
Description
Die vorliegende Erfindung bezieht sich auf einen Schutzkontaktstecker für an eine Netzsteckdose anschließbare elektrische Geräte.The present invention relates to a safety plug for electrical devices that can be connected to a mains socket.
Stecker dieser Art sind aus der zum Stand der Technik nach Artikel 54(3) EPÜ gehörenden EP-A-0 391 298 und der FR-A-2 538 625 bekannt und sie haben sich im großen und ganzen auch bewährt. Grundsätzlich haben derartige Schutzkontaktstecker die Aufgabe, die Handhabung eines elektrischen Gerätes, d.h. das Anschließen dieses Gerätes beim Einstecken des Anschlußsteckers in die Netzsteckdose nicht zu einer Gefahr dahingehend werden zu lassen, daß etwa aufgrund eines sogenannten Erdschlußes Personen gefährdet werden.Plugs of this type are known from EP-A-0 391 298 and FR-A-2 538 625, which belong to the state of the art under Article 54 (3) EPC and on the whole have also proven themselves. Basically, such protective contact plugs have the task of handling an electrical device, i.e. the connection of this device when plugging the connector into the power outlet does not become a danger that people may be at risk due to a so-called earth fault.
Die Herstellung und Konzeption der Schutzkontaktstecker unterliegen strengen Auflagen und Vorschriften. Bei der modernen, insbesondere automatisierten Massenherstellung ist besonderes Augenmerk darauf zu richten, daß die Leiteranschlüsse, d.h. die Stromleiter und der Schutzleiter, die mit dem Stecker verbunden sind und die die elektrische Verbindung zwischen dem Elektrizitätswerk einerseits und dem Gerät andererseits herstellen, einen hinreichenden Sicherheitsabstand zur Außenseite des Schutzkontaktsteckers haben. Schließlich besteht die Gefahr, daß sich einzelne Drähte der Leiter während der Herstellung beim Einführung in die Bohrungen der hohlzylindrischen Anschlußstifte beziehungsweise Anschlußbuchsen verbiegen und verkanten, so daß sie vom fertigen Stecker nach außen abstehen. Wird dies nicht bemerkt, so kann es vorkommen, daß die gegebenenfalls abstehenden Einzeldrähte durch die Oberfläche des fertig gespritzten Schutzkontaktsteckers hindurch ragen oder so nahe zur Außenseite hin liegen, daß bei der Handhabung ein Erdschluß entsteht.The manufacture and design of the safety plug are subject to strict requirements and regulations. In modern, especially automated mass production, special attention should be paid to ensuring that the conductor connections, i.e. the current conductors and the protective conductors, which are connected to the plug and which establish the electrical connection between the power plant on the one hand and the device on the other hand, provide a sufficient safety distance Outside of the safety plug. Finally, there is a risk that individual wires of the conductor during manufacture when inserted into the bores of the hollow cylindrical connecting pins or Bend and tilt the connection sockets so that they protrude outwards from the finished plug. If this is not noticed, it can happen that the possibly protruding individual wires protrude through the surface of the molded injection plug or are so close to the outside that an earth fault occurs during handling.
Die Person die den Stecker in die Steckdose steckt, kann dadurch einen gesundheitlichen Schaden erleiden, der sogar zum Tod führen kann.The person who plugs the plug into the socket can suffer health damage that can even lead to death.
Aus diesem Grunde werden die fertigen Schutzkontaktstecker jeweils einzeln mittels sogenannter Konturenprüfeinrichtungen auf ihre elektrische Sicherheit geprüft. Der Stecker wird dazu in eine seiner Form entsprechende Prüfform eingelegt und von außen elektrisch beaufschlagt. Auf diese Weise können Stecker mit nach außen durch stehenden beziehungsweise einen zu geringen Abstand aufweisenden Einzeldrähten eliminiert werden. Dies ist jedoch mit erheblichen Produktionskosten, d.h. Prüfkosten, verbunden.For this reason, the finished earthing contact 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 corresponding to its shape and electrically charged from the outside. In this way, plugs with individual wires that stand outwards or are too close apart can be eliminated. However, this is associated with significant production costs, i.e. Testing costs.
Die bekannten Stecker lösen die genannten Probleme nur teilweise. Zwar haben sie trichterförmige Einführhilfen, die in L-förmige Formteile eingearbeitet sind, aber einzelne Drähte der einzuführenden Litzen werden bei einem Verfehlen des Einführtrichters bei der Montage geknickt, eingerollt oder in sonstiger Weise verbogen. Die Ursache hierfür liegt in der Gestalt und Anordnung des horizontalen Abschnitts des L-förmigen Formteils. Bei den bekannten Versionen ist der Einführtrichter versenkt in einer ebenen Platte oder als Rohr mit Innenkonus auf einer ebenen Platte angeordnet. In beiden Fällen treffen die nicht eingefädelten Drähte nahezu senkrecht auf die ebene Fläche neben dem Einführtrichter, um dort verformt zu werden. Diese eingerollten und geknickten Drähte verklemmen sich beim weiteren Einführen in dem entsprechenden Einführtrichter mit der Litzenisolation. In vielen Fällen wird dadurch das Einführen vorzeitig beendet. Als Folge hiervon stehen die nicht eingefädelten Drähte weiter über und die Vercrimpung ist nicht sicher.The known plugs only partially solve the problems mentioned. Although they have funnel-shaped insertion aids, which are incorporated into L-shaped molded parts, individual wires of the strands to be inserted are kinked, rolled up or otherwise bent if the insertion funnel is missed during assembly. The reason for this lies in the shape and arrangement of the horizontal section of the L-shaped molded part. In the known versions, the insertion funnel is sunk in a flat plate or as a tube with an inner cone on a flat plate. In both cases, the unthreaded wires hit the flat surface next to the insertion funnel almost vertically in order to be deformed there. These rolled up and kinked wires jam with the strand insulation during further insertion in the corresponding insertion funnel. In many cases, the insertion is terminated prematurely. As a result, the unthreaded wires continue to protrude and the crimping is not secure.
Die der vorliegenden Erfindung zugrunde liegende Problemstellung ist darin zu sehen, daß etwa seitlich abstehende Einzeldrähtchen eines Leiters sicher "eingefangen" werden. Im Vordergrund steht jedoch die Aufgabe, einen Schutzkontaktstecker der gattungsgemäßen Art von vornherein, d.h. im Vorgriff auf die Einführung der abisolierten Leiterenden in die hohlzylindrischen Anschlußstifte, so auszubilden, daß diese Leiterenden von vornherein so sicher eingeführt werden können, daß keine Einzeldrähtchen abknicken können. Sollte wider Erwarten tatsächlich einmal ein Einzeldrähtchen abstehen, so muß Sorge dafür getragen sein, daß dieses sicher gefaßt wird.The problem underlying the present invention is to be seen in the fact that individual wires of a conductor that protrude laterally protrude "safely". In the foreground, however, the task is to design a protective contact plug of the generic type from the outset, ie in anticipation of the introduction of the stripped conductor ends into the hollow cylindrical connecting pins, in such a way that these conductor ends can be inserted from the outset so securely that no individual wires can kink. Should, contrary to expectations, a single wire actually stick out, care must be taken to ensure that it is gripped securely.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 spezifizierte Konfiguration gelöst.This object is achieved by the configuration specified in the characterizing part of
Der wesentliche Vorteil der erfindungsgemäßen Konzeption ist darin zu sehen, daß aufgrund der trichterförmigen Einführhilfe für das Ende des Schutzleiters die Montagezeiten, d.h. die Produktionszyklen für Stecker der gattungsgemäßen Art erheblich reduziert werden. Der wirtschaftliche Erfolg der vorliegenden Erfindung soll somit bereits jetzt ganz besonders hervorgehoben werden.The main advantage of the concept according to the invention can be seen in the fact that due to the funnel-shaped insertion aid for the end of the protective conductor, the assembly times, i.e. the production cycles for connectors of the generic type are significantly reduced. The economic success of the present invention should therefore already be emphasized in a very special way.
Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt
im Rahmen einer unbemaßten Konstruktionszeichnung in drei Ansichten die Einzelheiten einer kompletten aus Grundplatte und Erdungsfeder bestehenden Steckerbrücke.The invention is explained below with reference to the drawing. This shows
the details of a complete connector bridge consisting of a base plate and an earthing spring as part of an undimensioned construction drawing in three views.
Die Steckerbrücke 1 besteht aus einer im wesentlichen ebenen, etwa rautenförmigen (vergleiche Aufsicht) Grundplatte 20 aus hartelastischem Kunststoff, und einer Erdungsfeder 30, die form- und kraftschlüssig an zwei sich diametral gegenüberliegenden Verbindungsseiten aneinander anstoßenden Rautenseiten der Grundplatte 20 eingeklemmt ist (vergleiche Bezugszeichen 31) und quer über die Unterseite 21 der Grundplatte 20 verläuft (vergleiche Bezugszeichen 32). Von den genannten Klemmungen 31 ausgehend ragt die Erdungsfeder 30 beidseitig über die Oberseite 22 der Grundplatte 20 vor, und zwar so - vergleiche Grundansicht -, daß sich senkrecht abstehende Schenkel 33, 34 ergeben, zwischen denen ein Freiraum 11 an der Oberseite 22 der Grundplatte 20 definiert ist. Der eine Schenkel 33 der Erdungsfeder 30 bildet einen ebenen Seitensteg für den genannten Freiraum 11; der zweite Schenkel 34 der Erdungsfeder 30 ist so ausgebildet und verformt, daß eine Anschlußbuchse 35 für den Schutzleiteranschluß gebildet ist. Der Vollständigkeit halber sei noch erwähnt, daß die Querspange 32 der Erdungsfeder 30 eine Lasche 36 aufweist, die bei der Montage der Erdungsfeder 30 durch einen korrespondierenden Schlitz in die Grundplatte 20 greift und umgebogen wird (vergleiche Aufsicht).The
Die soweit beschriebene Steckerbrücke 1 ist elektrisch wie folgt bestückt:The
An der Unterseite 21 der Grundplatte 20 ragen im genormten Abstand zueinander und mit genormter Länge Kontaktstifte 40, 41 nach außen mit denen der Stecker letztlich in eine Netzsteckdose eingeführt wird. Die Kontaktstifte 40, 41 sitzen fest in entsprechenden Bohrungen der Grundplatte 20 und sie sind (am zweiten Ende) rückseitig soweit verlängert, daß sie in Form von hohlzylindrischen Anschlußstiften 42, 43 ins Innere des Freiraums 11 zwischen den Schenkeln 33, 34 der Erdungsfeder 30 ragen. Mit diesen Anschlußstiften 42, 43 werden letztlich die Stromleiter einer Verbraucherleitung mechanisch verbunden, insbesondere angeklemmt beziehungsweise angequetscht.On the
Das elektrische System wird letztlich durch den mit der Anschlußbuchse 35 der Erdungsfeder 30 verbundenen Schutzleiter und die mit den Anschlußstiften 42, 43 der Kontaktstifte 40, 41 verbundenen Stromleiter gebildet. Die Anschlußstifte 42, 43 der Stromleiter und die Anschlußbuchse 35 für den Schutzleiter sind etwa im Dreieck zueinander angeordnet, wobei die Verbindungslinie der Anschlußstifte 42, 43 senkrecht zur Achse des Querstegs 32 der Erdungsfeder 30 gerichtet ist.The electrical system is ultimately formed by the protective conductor connected to the connecting
Die soweit beschriebene Steckerbrücke 1 ist Stand der Technik. Beim Umspritzen dieser Steckerbrücke zwecks Endfertigung des Schutzkontaktsteckers können nun die eingangs genannten Probleme auftreten, d.h. bei seitlich abstehenden Einzeldrähtchen der Leiter kann es vorkommen, daß diese bis nach außen zum, ja gegebenenfalls durch den gespritzten Steckerkopf reichen.The
Um dieses Risiko gänzlich auszuschalten, ist die Steckerbrücke 1 wie nachstehend erläutert und beschrieben aus- und/oder weitergebildet.In order to completely eliminate this risk, the
An der Anschlußbuchse 35 für den Schutzleiter ist - vorzugsweise als integrierter Bestandteil der Spritzform für die Grundplatte 20 - ein diese Anschlußbuchse 35 überkragendes L-förmiges Formteil 50 angespritzt. Dieses Formteil 50 kragt über die Anschlußbuchse 35 hinaus und bildet zusammen mit einem Stützfuß 51 gemeinsam mit der Grundplatte 20 einen einstückigen Montagegrundkörper.An L-shaped molded
Die Anschlußbuchse 35 für den Schutzleiter ist somit vollständig überbrückt, wobei der vom L-Schenkel des Formteils 50 an der freien Vorderkante abgeknickte Kopfteil 52 dieser Anschlußbuchse 35 gegenüberliegt. Ein wesentliches Merkmal des Kopfteils 52 des Formteils 50 ist ein konisches Durchgangsloch, das koaxial zur Anschlußbuchse 35 für den Schutzleiter ausgerichtet ist. Der kleine Durchmesser dieses Durchgangslochs liegt der Stirnseite der Anschlußbuchse 35 gegenüber, so daß dieses zur freien Seite des Kopfteils 52 des Formteils 50 hin in eine trichterförmige Erweiterung übergeht. über diese trichterförmige Erweiterung läßt sich so das abisolierte Leitungsende des Schutzleiters leicht und sicher und ohne daß ein Einzeldrähtchen des Schutzleiters umgeknickt wird einführen.The
Für den Fall, daß wider Erwarten doch einmal ein Einzeldrähtchen des Schutzleiters abknicken und abstehen sollte, ist die Materialstärke des Kopfteils 52 mindestens so gewählt, daß - der Länge der Abisolierung des Schutzleiters entsprechend - dieses Einzeldrähtchen sicher hinter der Oberkante des Durchgangslochs und damit des Kopfteils 52 verschwindet.In the event that, contrary to expectations, a single wire of the protective conductor should bend and protrude, the material thickness of the
Der Schutzleiter läßt sich somit sicher mit Hilfe des Formteils 50 beziehungsweise des konischen Durchgangslochs einführen und fixieren, beispielsweise durch Quetschen (Crimpen).The protective conductor can thus be securely inserted and fixed with the aid of the
