Description

Die vorliegende Erfindung betrifft eine Steckerbrücke und ein Verfahren zur Herstellung einer Steckerbrücke. Insbesondere betrifft die vorliegende Erfindung eine Steckerbrücke für einen Schutzkontaktstecker nach British Standard BS 1363, sowie ein Verfahren zur Herstellung einer derartigen Steckerbrücke.The present invention relates to a plug bridge and a method for producing a plug bridge. In particular, the present invention relates to a connector bridge for a safety plug according to British Standard BS 1363, as well as a method for producing such a connector bridge.

Als Bauteil eines Steckers wird eine Steckerbrücke im Übergangsbereich zwischen einem Anschluss- bzw. Netzkabel und einer Steckdose verwendet. Die Steckerbrücke weist an ihrer Vorderseite mehrere Steckerstifte auf, mittels derer die Steckerbrücke in die Steckdose einschiebbar ist, wobei die Steckerstifte den elektrischen Kontakt zu den in der Steckdose befindlichen Kontaktfedern herstellen. Die Steckerstifte sind beispielsweise mit einem Schutzleiter, einem Neutralleiter und einem Außenleiter bzw. mit entsprechenden Adern des Anschluss- bzw. Netzkabels verbunden.As a component of a plug, a jumper in the transition region between a power cord and a power outlet is used. The plug bridge has on its front side a plurality of plug pins, by means of which the plug bridge can be inserted into the socket, wherein the plug pins make electrical contact with the contact springs located in the socket. The plug pins are connected, for example, with a protective conductor, a neutral conductor and an outer conductor or with corresponding wires of the connection or power cable.

Um die Steckerbrücke nach außen zu isolieren, und um die Handhabung beim Einstecken in und beim Herausziehen aus der Steckdose für den Anwender zu vereinfachen, ist die Steckerbrücke auf ihrer Rückseite üblicherweise mit einem Griffkörper versehen. Dieser Griffkörper kann als separates Bauteil in Form eines abnehmbaren Gehäuses ausgebildet sein oder durch Umspritzen der Steckerbrücke mittels eines elektrisch isolierenden Kunststoffs hergestellt werden.To isolate the plug bridge to the outside, and to facilitate handling when plugging in and pulling out of the socket for the user, the plug bridge is usually provided on its back with a handle body. This handle body may be formed as a separate component in the form of a removable housing or produced by molding the connector bridge by means of an electrically insulating plastic.

Das Dokument EP 0 016 269 A1 offenbart eine Steckerbrücke für einen Schutzkontaktstecker mit einem Grundkörper nd einer mit diesem verbindbaren Abdeckung. Der Grundkörper weist eine Sicherungskammer mit einem rechteckigen Loch auf, in das ein Träger mit Sicherungsklemmen und einer durch diese gestützte Sicherung einrastbar ist. Eine auf der Seite der Steckerstifte vorhandene Öffnung der Sicherungskammer ist mittels eines Deckels verschließbar.The document EP 0 016 269 A1 discloses a connector bridge for a safety plug with a base nd a connectable with this cover. The main body has a securing chamber with a rectangular hole into which a carrier with securing clamps and a fuse supported by this can be latched. An existing on the side of the plug pins opening of the fuse chamber is closed by means of a lid.

Aus dem Dokument GB 2 065 990 A ist eine mit drei Steckerstiften ausgebildete Steckerbrücke bekannt, die einen Hohlraum zur Aufnahme einer Sicherung aufweist. Der Hohlraum ist mittels eines am Grundkörper der Steckerbrücke verschwenkbar angeordneten Deckels verschließbar.From the document GB 2 065 990 A a connector bridge formed with three pins is known, which has a cavity for receiving a fuse. The cavity can be closed by means of a cover pivotably arranged on the base body of the plug bridge.

In dem Dokument GB 2 140 222 A ist ein Schutzkontaktstecker offenbart, der eine Steckerbrücke und eine Abdeckung aufweist. Die Steckerbrücke weist Sicherungsklemmen zur Aufnahme einer Sicherung auf. Dieser Schutzkontaktstecker wird in eine Gießform eingesetzt und umspritzt. Ob dabei auch die Sicherung mit eingegossen wird, ist in dem Dokument unserer Auffassung nach nicht eindeutig offenbartIn the document GB 2 140 222 A a safety plug is disclosed which has a plug bridge and a cover. The jumper has fuse terminals for receiving a fuse. This safety plug is inserted into a mold and molded around. Whether or not the security is also cast in the document is, in our opinion, not clearly disclosed

Aus dem Dokument GB 2 088 654 A ist ein Schutzkontaktstecker bekannt, der einen Grundkörper, eine Abdeckung und einen Sicherungshalter mit eingesetzter Sicherung aufweist. Die gesamte Anordnung wird mit einem Kunststoffkörper umspritzt.From the document GB 2 088 654 A a safety plug is known, which has a base body, a cover and a fuse holder with inserted fuse. The entire assembly is overmoulded with a plastic body.

Das Dokument US 6 267 627 B1 offenbart einen Schutzkontaktstecker mit einer auswechselbaren Sicherung. Der Schutzkontaktstecker weist ein Gehäuse und einen Deckel auf, wobei das Gehäuse eine in Steckrichtung offene Kammer aufweist. Die Sicherung wird auf einem Deckel durch zwei Rastelemente gehalten, wobei der Deckel die Kammer verschließt.The document US Pat. No. 6,267,627 B1 discloses a grounded plug with a replaceable fuse. The safety plug has a housing and a lid, wherein the housing has a chamber open in the plug-in direction. The fuse is held on a lid by two locking elements, the lid closing the chamber.

Aus dem Dokument GB 1 259 497 A ist ein Schutzkontaktstecker bekannt, der ein oberes Gehäuseteil und ein unteres Gehäuseteil umfaßt. Das untere Gehäuseteil weist eine Ausnehmung auf, in die eine Abdeckplatte mit daran montierter Sicherung einsetzbar ist.From the document GB 1 259 497 A For example, a safety plug is known which comprises an upper housing part and a lower housing part. The lower housing part has a recess into which a cover plate with fuse mounted thereon can be inserted.

Das dem Oberbegriff des Patentanspruchs 1 entsprechende Dokument GB 2 282 713 A offenbart eine Steckerbrücke für einen Schutzkontaktstecker mit einer Grundplatte , die eine integral ausgebildete Sicherungskammer umfaßt, und die eine Aussparung aufweist, die mittels eines Deckels , der eine Klemme für eine Sicherung aufweist, verschlossen werden kann. Die Klemme dient zur mechanischen Verbindung der Sicherung mit dem Deckel, währenddessen Sicherungskontaktklemmen zur elektrischen Verbindung mit der Sicherung im Boden der Sicherungskammer befestigt sind.The document corresponding to the preamble of claim 1 GB 2 282 713 A discloses a plug-in bridge for a grounded plug having a base plate comprising an integrally formed fuse box and having a recess which can be closed by means of a lid having a clip for a fuse. The terminal is used to mechanically connect the fuse to the cover, while fuse contact terminals are fixed in the bottom of the fuse box for electrical connection to the fuse.

Aus dem Dokument GB 2 152 301 A ist eine Steckerbrücke bekannt, die eine Aussparung für eine elektrische Sicherung aufweist. In dem Bereich der Aussparung sind Kontaktklemmen zum Kontakt mit der Sicherung vorgesehen. Die Sicherung wird durch einen Träger gehalten, der in die Aussparung eingesetzt wird und diese verschließt.From the document GB 2 152 301 A For example, a connector bridge is known which has a recess for an electrical fuse. In the region of the recess contact terminals are provided for contact with the fuse. The fuse is held by a carrier which is inserted into the recess and closes it.

Bei der automatisierten Fertigung von Steckerbrücken kommen üblicherweise gestanzte Metallbleche als elektrische Leiter zur Kontaktierung der Steckerstifte zum Einsatz. Diese Metallbleche werden üblicherweise umgeformt, wobei einzelne Bereiche der Metallbleche durch entsprechende Aussparungen in einer Grundplatte der Steckerbrücke gesteckt werden. Um die Montierbarkeit zu ermöglichen, ist es erforderlich, dass die Aussparungen in der Grundplatte geringfügig größer sind als die Außenabmessungen der durchzusteckenden Bereiche der Metallbleche. Im montierten Zustand sind daher Spalten zwischen den Rändern der Aussparung und den Metallflächen vorhanden, durch die unter ungünstigen Umständen Feuchtigkeit von außen eindringen kann. Durch die Feuchtigkeit werden innerhalb des Steckers bzw. auf der Steckerbrücke die Kriechstrecken verkürzt, so dass es während des Betriebs zu Kurzschlüssen kommen kann.In the automated production of connector bridges are usually punched metal sheets as electrical conductors for contacting the connector pins used. These metal sheets are usually formed, with individual areas of the metal sheets are inserted through corresponding recesses in a base plate of the connector bridge. In order to enable the mountability, it is necessary that the recesses in the base plate are slightly larger than the outer dimensions of durchzusteckenden areas of the metal sheets. In the assembled state, therefore, there are gaps between the edges of the recess and the metal surfaces through which moisture can penetrate from the outside under unfavorable circumstances. Due to the moisture inside the plug or on the Plug bridge the creepage distances shortened, so that it can lead to short circuits during operation.

Diese Gefahr besteht insbesondere, wenn die Steckerbrücke nicht vollständig mit einem Isolierkörper umspritzt werden kann, beispielsweise weil Teile der Steckerbrücke von außen zugänglich sein müssen. Bei Schutzkontaktsteckern nach BS 1363 ist es beispielsweise erforderlich, dass jeder Stecker mit einer elektrischen Sicherung, üblicherweise einer Feinsicherung, versehen ist, die in einer Sicherungskammer im Stecker angeordnet ist. Um eine zerstörte Sicherung zu ersetzen, muss diese Sicherungskammer auf einfache Art und Weise von außen zugänglich sein, wodurch sich die Gefahr erhöht, dass Feuchtigkeit in den Stecker bzw. die Steckerbrücke eindringt.This danger exists in particular if the plug bridge can not be completely encapsulated with an insulating body, for example because parts of the plug bridge must be accessible from the outside. With BS 1363 earthing contact plugs, it is necessary, for example, for each plug to be provided with an electrical fuse, usually a microfuse, which is arranged in a fuse chamber in the plug. In order to replace a broken fuse, this fuse chamber must be easily accessible from the outside, thereby increasing the risk of moisture entering the plug or the plug bridge.

Darüber hinaus besteht bei Steckerbrücken generell die Gefahr, dass diese im Betrieb überhitzen, auch wenn die üblichen Betriebsparameter, wie Stromstärke und Spannung eingehalten werden.In addition, plug-in bridges generally run the risk of overheating during operation, even if the usual operating parameters, such as current intensity and voltage, are complied with.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Steckerbrücke und ein Verfahren zur Herstellung einer Steckerbrücke anzugeben, durch die die Sicherheit bei nicht optimalen Betriebsbedingungen der Steckerbrücke im Stecker erhöht werden kann.It is therefore an object of the present invention to provide a connector bridge and a method for producing a connector bridge, through which the safety can be increased in non-optimal operating conditions of the connector bridge in the connector.

Erfindungsgemäß gelöst wird diese Aufgabe durch die merkmalen des Anspruchs 1.This object is achieved according to the invention by the features of claim 1.

Die Grundplatte und der Deckel sind aus elektrisch isolierendem Material hergestellt. Da die elektrische Sicherungseinrichtung zumindest teilweise in den Deckel integriert ist, wird die Wirkung der Isolation verbessert. Dies ist insbesondere für Schutzkontaktstecker nach BS 1363 von Vorteil. Ebenfalls wird die Montierbarkeit der Steckerbrücke verbessert, wenn nicht alle elektrischen Bauelemente auf der Grundplatte selbst zu montieren sind.The base plate and the lid are made of electrically insulating material. Since the electrical safety device is at least partially integrated in the lid, the effect of the insulation is improved. This is particularly advantageous for safety plug according to BS 1363. Also, the mountability of the connector bridge is improved, if not all electrical components are to be mounted on the base itself.

Vorzugsweise ragt die elektrische Sicherungseinrichtung vom Deckel ausgehend zumindest teilweise in die Aussparung der Grundplatte hinein.

Durch die überstehende Wand wird der für die elektrische Sicherungseinrichtung zur Verfügung stehende Raum vergrößert, wodurch die elektrische Sicherung einfacher herausgenommen und wieder eingesetzt werden kann.Preferably, the recess of the base plate is bordered by a protruding, preferably circumferential, wall. The protruding wall increases the space available for the electrical safety device, making it easier to remove and reinsert the electrical fuse.

Weiterhin vorzugsweise ist zwischen der Wand und dem Deckel eine Nut- und Federverbindung vorgesehen, wodurch die Abdichtung zwischen der Wand und dem Deckel verbessert wird.Further preferably, a tongue and groove connection is provided between the wall and the lid, whereby the seal between the wall and the lid is improved.

Insbesondere ist es von Vorteil, wenn die Wand und der Deckel stoffschlüssig miteinander verbunden sind.In particular, it is advantageous if the wall and the lid are materially connected to one another.

Gemäß einem weiteren bevorzugten Ausführungsbeispiel ist auf zumindest einer Seite des Deckels und/oder zumindest einem im Deckel integrierten, elektrischen Leiter und/oder zumindest einem Sicherungshalter eine Kühleinrichtung vorgesehen. Durch die Kühleinrichtung wird während des Betriebs die Ableitung der Wärme, die aufgrund des elektrischen Widerstands in den Leitern entsteht, verbessert.According to a further preferred exemplary embodiment, a cooling device is provided on at least one side of the cover and / or at least one electrical conductor integrated in the cover and / or at least one fuse holder.

Durch die Kühleinrichtung wird während des Betriebs die Ableitung von Wärme, die aufgrund des elektrischen Widerstands in den elektrischen Bauelementen entsteht, verbessert, wodurch ein Überhitzen der Steckerbrücke bzw. des Steckers, in dem die Steckerbrücke enthalten ist, auch bei ungünstigen Betriebsbedingungen verhindert wird. Insbesondere ist dies für Steckerbrücken von Schutzkontaktsteckern nach BS 1363 von Vorteil, die eine Sicherungseinrichtung aufweisen.By the cooling device, the dissipation of heat, which arises due to the electrical resistance in the electrical components, improved during operation, whereby overheating of the plug bridge or the plug, in which the plug bridge is included, even in adverse operating conditions is prevented. In particular, this is for connector bridges of earthing contacts to BS 1363 advantage that have a security device.

Vorzugsweise ist die Kühleinrichtung integral mit dem elektrischen Leiter ausgebildet, wodurch die Steckerbrücke kostengünstig herstellbar ist.Preferably, the cooling device is formed integrally with the electrical conductor, whereby the connector bridge is inexpensive to produce.

Gemäß einem weiteren bevorzugten Ausführungsbeispiel weist die Kühleinrichtung eine Vielzahl von regelmäßig angeordneten Vorsprüngen auf.According to a further preferred embodiment, the cooling device has a multiplicity of regularly arranged projections.

Die vorgenannte Aufgabe wird ferner erfindungsgemäß gelöst durch ein Verfahren zur Herstellung einer Steckerbrücke, wobei eine elektrische Sicherungseinrichtung zumindest teilweise in eine Grundplatte und/oder einen Deckel der Steckerbrücke eingegossen wird.The aforementioned object is further achieved according to the invention by a method for producing a plug bridge, wherein an electrical safety device is at least partially cast in a base plate and / or a cover of the plug bridge.

Da die Grundplatte und/oder der Deckel aus elektrisch isolierendem Material hergestellt werden, wird durch das Eingießen die Wirkung der Isolation verbessert. Insbesondere ist dies bei der Herstellung von Steckerbrücken für Schutzkontaktstecker nach BS 1363 vorteilhaft.Since the base plate and / or the lid are made of electrically insulating material, pouring improves the effect of the insulation. In particular, this is advantageous in the production of plug bridges for earthing contact plug to BS 1363.

Es ist von Vorteil, wenn die Grundplatte mit einer Aussparung hergestellt wird, die elektrische Sicherungseinrichtung zumindest teilweise in den Deckel eingegossen wird, und der Deckel mit der Grundplatte verbunden wird derart, dass die elektrische Sicherungseinrichtung zumindest teilweise in die Aussparung hineinragt. Hierdurch wird die Montierbarkeit verbessert, da nicht mehr alle elektrischen Bauelemente direkt auf die Grundplatte montiert werden.It is advantageous if the base plate is made with a recess, the electrical safety device is at least partially poured into the lid, and the lid is connected to the base plate such that the electrical safety device at least partially protrudes into the recess.

In den Figuren 1a bis 4 ist ein besonders bevorzugtes Ausführungsbeispiel einer Steckerbrücke 1 dargestellt, nämlich eine Steckerbrücke 1 für einen Schutzkontaktstecker nach dem englischen Standard BS 1363. Die nachfolgende Erfindung ist jedoch nicht auf einen derartigen Stecker begrenzt, sondern allgemein auf Steckerbrücken 1 anwendbar, insbesondere auf solche Steckerbrücken 1, die eine integrierte, elektrische Sicherungseinrichtung 5 aufweisen.In the FIGS. 1a to 4 a particularly preferred embodiment of a connector bridge 1 is shown, namely a connector bridge 1 for a safety plug according to the English standard BS 1363. However, the following invention is not limited to such a connector, but generally applicable to connector bridges 1, in particular to such connector bridges 1, the have an integrated, electrical safety device 5.

In Figur 2 ist eine Grundplatte 2 der Steckerbrücke 1 in einer perspektivischen Darstellung gezeigt. Die Grundplatte 2 stellt ein tragendes Bauteil der Steckerbrücke 1 dar. Von einer Vorderseite (steckdosenseitige Seite) der Grundplatte 2 erstrecken sich im dargestellten Ausführungsbeispiel drei Steckerstifte 9a, 9b, 9c, die Federkontakte einer Steckdose kontaktieren, wenn die Steckerbrücke 1 bzw. der Stecker, in dem die Steckerbrücke 1 enthalten ist, in die Steckdose eingeschoben ist.In FIG. 2 a base plate 2 of the connector bridge 1 is shown in a perspective view. The base plate 2 is a supporting component of the connector bridge 1. From a front side (plug side side) of the base plate 2 extend in the illustrated embodiment, three connector pins 9a, 9b, 9c, the spring contacts a socket contact when the connector bridge 1 and the plug, in which the connector bridge 1 is included, is inserted into the socket.

Die Steckerstifte 9a, 9b, 9c sind in den Ecken eines Dreiecks angeordnet und mit der Grundplatte 2 verbunden. Das Bezugszeichen 9a bezeichnet einen Erdungssteckerstift, der im Vergleich zu den beiden anderen Steckerstiften 9b, 9c länger ist und vorauseilend angeordnet ist, so dass der Erdungssteckerstift 9a der erste Steckerstift ist, der beim Einschieben in die Steckdose die Erding herstellt, und der letzte Steckerstift ist, der beim Herausziehen aus der Steckdose die Erdung unterbricht.The plug pins 9 a, 9 b, 9 c are arranged in the corners of a triangle and connected to the base plate 2. The reference numeral 9a designates a ground pin which is longer and preceded in comparison with the other two pin pins 9b, 9c, so that the ground pin 9a is the first pin which makes the erythmus when it is inserted into the socket, and the last pin is , which disconnects the grounding when pulled out of the socket.

Abhängig von der zugrundeliegenden Steckernorm sind natürlich auch andere Ausgestaltungen der Grundplatte 2 und/oder der Steckerstifte 9a, 9b, 9c möglich. Insbesondere können auch mehr als drei Steckerstifte vorgesehen sein, beispielsweise wenn ein Dreiphasen- oder Mehrphasenstrom zu übertragen ist.Of course, other configurations of the base plate 2 and / or the plug pins 9a, 9b, 9c are possible depending on the underlying plug standard. In particular, more than three plug pins may be provided, for example, when a three-phase or multi-phase current is to be transmitted.

Die Grundplatte 2 besteht vorzugsweise aus einem elektrisch isolierenden Material, das den gestellten Anforderungen entspricht, beispielsweise aus einem Kunststoff wie Polyamid (PA) oder Polybutylenterephthalat (PBTB). Jedoch ist es auch möglich, die Grundplatte 2 aus einem keramischen Material herzustellen.The base plate 2 is preferably made of an electrically insulating material that meets the requirements, such as a plastic such as polyamide (PA) or polybutylene terephthalate (PBTB). However, it is also possible to manufacture the base plate 2 from a ceramic material.

Zwischen dem Erdungssteckerstift 9a auf der einen Seite und den beiden weiteren Steckerstiften 9b, 9c auf der anderen Seite weist die Grundplatte 2 vorzugsweise eine Aussparung 4 auf. Die Aussparung 4 kann jedoch beispielsweise auch derart angeordnet sein, dass sich eine Längsachse der Aussparung 4 im Wesentlich von nur einem der weiteren Steckerstifte 9b, 9c ausgehend bis neben den Erdungssteckerstift 9a erstreckt.Between the grounding pin 9a on one side and the two other connector pins 9b, 9c on the other side, the base plate 2 preferably has a recess 4. However, the recess 4 may, for example, also be arranged in such a way that a longitudinal axis of the recess 4 essentially extends from only one of the further plug pins 9b, 9c up to the grounding plug pin 9a.

In dem in Fig. 2 dargestellten Ausführungsbeispiel hat die Aussparung 4 einen im Wesentlichen rechteckigen Querschnitt und ist von einer umlaufenden, überstehenden Wand 11 eingefasst. Vorzugsweise ist die Wand 11 auf der Rückseite (griffseitige Seite) der Grundplatte 2 ausgebildet, d.h. auf der Seite, die von der Steckdose wegzeigt, wenn die Steckerbrücke 1 bzw. der die Steckerbrücke 1 enthaltende Stecker in die Steckdose eingesteckt ist. In Abhängigkeit von der Einteilung des zur Verfügung stehenden Raums ist es jedoch auch möglich, dass die Wand 11 auf der Vorderseite (steckdosenseitige Seite) der Grundplatte 2 übersteht oder auf der Vorderseite und der Rückseite der Grundplatte 2 übersteht.In the in Fig. 2 illustrated embodiment, the recess 4 has a substantially rectangular cross section and is surrounded by a circumferential, projecting wall 11. Preferably, the wall 11 on the back (handle side) of the base plate 2 is formed, ie on the side facing away from the socket when the connector bridge 1 and the plug bridge 1 containing plug is plugged into the socket. Depending on the division of the available space, however, it is also possible that the wall 11 projects on the front side (plug-side side) of the base plate 2 or protrudes on the front side and the rear side of the base plate 2.

Am freien Rand der Wand 11 ist vorzugsweise eine Dichtanordnung angeordnet, um den Übergang zu einem Deckel 3 abzudichten, auf den nachfolgend noch eingegangen werden wird. Die Dichteinrichtung kann beispielsweise als Nut oder Feder einer umlaufenden Nut- und Federverbindung 12 ausgeführt sein, kann jedoch auch als separate Dichtlippe auf dem Rand der Wand 11 aufgebracht sein.At the free edge of the wall 11, a sealing arrangement is preferably arranged to seal the transition to a lid 3, will be discussed in the following. The sealing device may be designed, for example, as a tongue or groove of a circumferential tongue and groove joint 12, but may also be applied as a separate sealing lip on the edge of the wall 11.

In den Figuren 3a bis 3c ist der Deckel 3 der Steckerbrücke 1 in verschiedenen Ansichten gezeigt, während in Fig. 4 im Deckel 3 zumindest teilweise integrierte, elektrische (leitende) Bauelemente ohne den Deckel 3 selbst dargestellt sind.In the FIGS. 3a to 3c the cover 3 of the connector bridge 1 is shown in different views, while in Fig. 4 in the lid 3 at least partially integrated, electrical (conductive) components are shown without the lid 3 itself.

Im dargestellten Ausführungsbeispiel sind elektrische (leitende) Bauelemente der Steckerbrücke 1 zumindest teilweise in den Deckel 3 integriert. Diese Integration ist insbesondere stoffschlüssig, wobei der Deckel 3 vorzugsweise als Spritzgussbauteil ausgeführt ist, in das die elektrischen Bauelemente zumindest teilweise eingespritzt sind. Neben der Grundplatte 2 stellt somit auch der Deckel 3 ein tragendes Bauteil für elektrische Bauelemente der Steckerbrücke 1 dar.In the illustrated embodiment, electrical (conductive) components of the connector bridge 1 are at least partially integrated in the lid 3. This integration is in particular cohesively, wherein the lid 3 is preferably designed as an injection-molded component, in which the electrical components injected at least partially are. In addition to the base plate 2 thus also the cover 3 is a supporting component for electrical components of the connector bridge 1.

Diese elektrischen Bauelemente umfassen Teile der elektrischen Sicherungseinrichtung 5 sowie Teile elektrischer Leiter 8a, 8b, 8c.These electrical components comprise parts of the electrical safety device 5 and parts of electrical conductors 8a, 8b, 8c.

Die elektrische Sicherungseinrichtung 5 beinhaltet zwei einander gegenüberliegende Sicherungshalter 6, in die eine elektrische Sicherung 7, beispielsweise eine Feinsicherung, einsetzbar ist. Sockelbereiche der Sicherungshalter 6 sind in den Deckel 3 derart integriert, dass die freien Enden des Sicherungshalters 6 auf der Vorderseite (steckdosenseitige Seite) des Deckels 3 aus dem Deckel 3 herausragen (Fig. 3b), um die elektrische Sicherung 7 darin aufzunehmen (Fig. 4) und von außen zugänglich zu machen. Beispielsweise sind die freien Enden der Sicherungshalter 6 als Klemmfedern ausgeführt, um Enden der elektrischen Sicherung 7 zumindest teilweise zu umschließen.The electrical safety device 5 includes two mutually opposite fuse holder 6, in which an electrical fuse 7, for example, a micro-fuse, can be used. Base regions of the fuse holder 6 are integrated in the cover 3 such that the free ends of the fuse holder 6 on the front side (plug-side side) of the cover 3 protrude from the cover 3 ( Fig. 3b ) to receive the electrical fuse 7 therein ( Fig. 4 ) and accessible from the outside. For example, the free ends of the fuse holder 6 are designed as clamping springs to at least partially enclose ends of the electrical fuse 7.

Ferner sind in dem dargestellten Ausführungsbeispiel ein zum Sicherungshalter 6 führender elektrischer Leiter 8a und ein vom Sicherungshalter 6 wegführender elektrischer Halter 8b teilweise in den Deckel 3 integriert. Vorzugsweise sind diese elektrischen Leiter 8a, 8b einteilig mit den jeweiligen Sicherungshaltern ausgebildet und aus Metallblechen, vorzugsweise Messingblechen, hergestellt.Further, in the illustrated embodiment, an electrical conductor 8a leading to the fuse holder 6 and an electrical holder 8b leading away from the fuse holder 6 are partially integrated in the lid 3. Preferably, these electrical conductors 8a, 8b are formed integrally with the respective fuse holders and made of metal sheets, preferably brass sheets.

In den Deckel 3 ist ferner ein Teil eines elektrischen Leiters 8c integriert, der den Erdungssteckerstift 9a kontaktiert. Dieser elektrische Leiter 8c verläuft zwischen den beiden Sockelbereichen der einander gegenüberliegenden Sicherungshalter 6 durch den Deckel 3. Jedoch ist es auch möglich, nicht alle der vorgenannten elektrischen Bauelemente in den Deckel 3 zu integrieren. Beispielsweise kann der elektrische Leiter 8c auch direkt auf der Grundplatte 2 befestigt werden oder in diese integriert werden.In the cover 3, a part of an electrical conductor 8c is further integrated, which contacts the grounding pin 9a. This electrical conductor 8c extends between the two base areas of the mutually opposite fuse holder 6 through the cover 3. However, it is also possible not to integrate all of the aforementioned electrical components in the cover 3. For example, the electrical conductor 8c can also be attached directly to the base plate 2 or integrated into it.

Freie Enden des zum Sicherungshalter 6 führenden elektrischen Leiters 8a und des zum Erdungssteckerstift 9a führenden elektrischen Leiters 8c weisen Aufnahmehülsen 10 auf, die vorzugsweise einteilig mit den elektrischen Leitern 8a, 8c ausgebildet sind. Diese Aufnahmehülsen 10 dienen der zuverlässigen Verbindung und elektrischen Kontaktierung der Leiter 8a, 8c mit entsprechenden Adern eines Anschluss- bzw. Netzkabels.Free ends of the fuse holder 6 leading electrical conductor 8a and the earthing pin 9a leading electrical conductor 8c have receiving sleeves 10, which are preferably integrally formed with the electrical conductors 8a, 8c. These receiving sleeves 10 serve the reliable connection and electrical contacting of the conductors 8a, 8c with corresponding wires of a connecting or mains cable.

Für die automatisierte Fertigung bietet es sich an, die Aufnahmehülsen 10 als Crimphülsen auszubilden. Für manuell zu montierende Stecker ist es jedoch auch möglich, die Aufnahmehülsen 10 mit Schrauben oder anderen Klemmeinrichtungen zur Verbindung mit den entsprechenden Adern des Anschluss- bzw. Netzkabels zu versehen.For automated production, it makes sense to form the receiving sleeves 10 as Crimphülsen. However, for manually mounted connector, it is also possible to provide the receiving sleeves 10 with screws or other clamping devices for connection to the corresponding wires of the power cord.

Der Deckel 3 kann aus einem ähnlichen oder dem gleichen Material wie die Grundplatte 2 ausgebildet sein. Insbesondere ist es daher von Vorteil, den Deckel 3 aus einem hinsichtlich Verarbeitbarkeit und Isolationsvermögen und Alterungsbeständigkeit geeigneten Kunststoff, wie z.B. Polyamid (PA) oder Polybutylenterephthalat (PBTB), herzustellen. Jedoch ist es auch möglich, den Deckel 3 aus einem keramischen Material herzustellen.The cover 3 may be formed of a similar or the same material as the base plate 2. In particular, it is therefore advantageous to provide the lid 3 with a plastic suitable for processability and insulating capacity and resistance to aging, such as e.g. Polyamide (PA) or polybutylene terephthalate (PBTB). However, it is also possible to make the lid 3 of a ceramic material.

Die Form des Deckels 3 entspricht weitestgehend der Außenkontur der Aussparung 4, bzw. der Außenkontur der überstehenden Wand 11, die die Aussparung 4 umgibt. Jedoch ist es auch möglich, die Fläche des Deckels 3 etwas größer zu gestalten, insbesondere wenn die im Deckel 3 integrierten, elektrischen Leiter 8a, 8b, 8c von einem direkt auf der Grundplatte 2 montierten, elektrischen Leiter 8d zu beabstanden und zu isolieren sind. Hierfür ist es möglich, eine Außenkante des Deckels 3 bis an die Aufnahmehülsen 10 heranzuführen.The shape of the lid 3 largely corresponds to the outer contour of the recess 4, or the outer contour of the protruding wall 11, which surrounds the recess 4. However, it is also possible to make the surface of the lid 3 somewhat larger, in particular if the electrical conductors 8a, 8b, 8c integrated in the lid 3 are to be spaced and insulated from an electrical conductor 8d mounted directly on the base plate 2. For this purpose, it is possible to bring an outer edge of the lid 3 up to the receiving sleeves 10.

Auf seiner Vorderseite (steckdosenseitige Seite), d.h. der Seite mit der der Deckel 3 auf der überstehenden Wand 11 aufliegt, kann der Deckel 3 ebenfalls mit einer vorzugsweise umlaufenden Dichteinrichtung versehen sein. Beispielsweise kann es sich hierbei um eine Feder oder Nut der Nut- und Federverbindung 12 handeln, die der Nut oder Feder der Wand 11 entspricht. Auch eine separate Dichtlippe ist möglich.On its front side (plug-side side), i. the side with which the lid 3 rests on the protruding wall 11, the lid 3 may also be provided with a preferably circumferential sealing means. For example, this may be a spring or groove of the tongue and groove joint 12, which corresponds to the groove or tongue of the wall 11. A separate sealing lip is also possible.

In den Figuren 1 a und 1 b ist der Deckel 3 aus den Figuren 3a bis 3c mit der Grundplatte 2 aus Fig. 2 verbunden. Die umlaufende Feder der überstehenden Wand 11 greift in die umlaufende Nut auf der Vorderseite (steckdosenseitige Seite) des Deckels 3 ein, um eine zuverlässige Verbindung zwischen der Grundplatte 2 und dem Deckel 3 zu erzielen.In the FIGS. 1 a and 1 b is the lid 3 from the FIGS. 3a to 3c with the base plate 2 off Fig. 2 connected. The encircling spring of the protruding wall 11 engages in the circumferential groove on the front side (plug-side side) of the lid 3 in order to achieve a reliable connection between the base plate 2 and the lid 3.

Alternativ oder zusätzlich ist es möglich, den Deckel 3 mit der Grundplatte 2 stoffschlüssig zu verbinden. Insbesondere wenn die Grundplatte 2 und der Deckel 3 aus thermoplastischem Kunststoff bestehen, ist es von Vorteil, die Grundplatte 2 und den Deckel 3 mittels Ultraschallschweißen oder anderen Verbindungsarten, (z.B. Reibschweißen oder Kleben) zu verbinden. Dadurch wird sichergestellt, dass in diesem Bereich keine Feuchtigkeit von außen in die Steckerbrücke 1 bzw. den Stecker eindringen kann.Alternatively or additionally, it is possible to connect the lid 3 with the base plate 2 cohesively. In particular, when the base plate 2 and the cover 3 are made of thermoplastic material, it is advantageous, the base plate 2 and the lid 3 by means of ultrasonic welding or other types of connection, (eg friction welding or gluing). This ensures that no moisture can penetrate from outside into the plug bridge 1 or the plug in this area.

Eine weitere Aufnahmehülse 10 ist zwischen den Aufnahmehülsen 10 des zum Sicherungshalter 6 führenden elektrischen Leiters 8a und des zum Erdungssteckerstift 9a führenden elektrischen Leiters 8c angeordnet. Diese weitere Aufnahmehülse 10 ist mit einem weiteren elektrischen Leiter 8d verbunden, der direkt mit dem in Fig. 1 a dargestellten linken Steckerstift 9b verbunden ist (Neutralleiter). Hierzu ist der weitere elektrische Leiter 8d vorzugsweise nicht in den Deckel 3 integriert, sondern direkt mit der Grundplatte 2 verbunden und kann beispielsweise auch in diese eingegossen sein.Another receiving sleeve 10 is arranged between the receiving sleeves 10 of the fuse holder 6 leading electrical conductor 8a and the grounding pin 9a leading electrical conductor 8c. This further receiving sleeve 10 is connected to a further electrical conductor 8 d, which is directly connected to the in Fig. 1 a shown left pin 9b is connected (neutral). For this purpose, the further electrical conductor 8d is preferably not integrated in the cover 3, but connected directly to the base plate 2 and may for example also be cast into this.

Die in Fig. 1a dargestellte linke Aufnahmehülse 10 ist über den zum Sicherungshalter 6 führenden elektrischen Leiter 8a, die beiden Sicherungshalter 6 und die darin eingesetzte elektrische Sicherung 7, sowie den vom Sicherungshalter 6 wegführenden elektrischen Leiter 8b mit dem rechten Steckerstift 9c verbunden (Außenleiter). Die Verbindung erfolgt somit durch elektrische (leitende) Bauelemente, die im Deckel 3 integriert sind bzw. durch diesen getragen werden.In the Fig. 1a shown left receiving sleeve 10 is connected to the fuse holder 6 leading electrical conductor 8a, the two fuse holder 6 and the electrical fuse inserted therein 7, and the leading away from the fuse holder 6 electrical conductor 8b with the right pin 9c (outer conductor). The connection is thus made by electrical (conductive) components that are integrated in the cover 3 and are supported by this.

Die in Fig. 1 a dargestellte rechte Aufnahmehülse 10 ist über den elektrischen Leiter 8c direkt mit dem Erdungssteckerstift 9a verbunden (Schutzleiter), wobei der elektrische Leiter 8c ebenfalls teilweise in den Deckel 3 integriert ist. Jedoch sind auch andere Verbindungsschemata für Schutzleiter, Neutralleiter und Außenleiter möglich.In the Fig. 1 A shown right receiving sleeve 10 is connected via the electrical conductor 8c directly to the ground pin 9a (protective conductor), wherein the electrical conductor 8c is also partially integrated in the lid 3. However, other connection schemes for protective conductor, neutral and outer conductor are possible.

Wie in Fig. 1b dargestellt, deckt der Deckel 3 die Aussparung 4 derart ab, dass die elektrische Sicherungseinrichtung 5, die zumindest teilweise im Deckel 3 integriert ist, vom Deckel 3 ausgehend in die Aussparung 4 hineinragt. Insbesondere ragen die freien, vorzugsweise federnden Enden des Sicherungshalters 6 in die Aussparung 4 hinein. Somit bilden die Wände 11 und der Deckel 3 die Wände und den Boden einer Sicherungskammer der Steckerbrücke 1 bzw. des Steckers. Eine Abdeckung (ohne Bezugszeichen) deckt auf der Vorderseite zwischen dem Erdungssteckerstift 9a und den weiteren Steckerstiften 9b, 9c die Sicherungskammer nach außen hin ab.As in Fig. 1b illustrated, the cover 3 covers the recess 4 such that the electrical safety device 5, which is at least partially integrated in the lid 3, protruding from the lid 3, starting in the recess 4. In particular, the free, preferably resilient ends of the fuse holder 6 protrude into the recess 4. Thus, the walls 11 and the lid 3 form the walls and the bottom of a fuse chamber of the plug bridge 1 and the plug. A cover (without reference numeral) covers on the front side between the ground pin 9a and the other connector pins 9b, 9c, the fuse chamber to the outside.

Zur Herstellung der Steckerbrücke 1 ist es von Vorteil, die Grundplatte 2 mit der Aussparung 4 einteilig, beispielsweise in einem Spritzgussprozess aus elektrisch isolierendem, den gestellten Anforderungen hinsichtlich Verarbeitbarkeit und Wirtschaftlichkeit, Isolationsvermögen und Alterungsbeständigkeit entsprechenden Kunststoff, wie z.B. Polyamid (PA) oder Polybutylenterephthalat (PBTB), herzustellen.For the preparation of the connector bridge 1, it is advantageous, the base plate 2 with the recess 4 in one piece, for example, in an injection molding process of electrically insulating, the requirements set in terms of workability and cost-effectiveness, Insulation capacity and aging resistance corresponding plastic, such as polyamide (PA) or polybutylene terephthalate (PBTB) produce.

Auch der Deckel 3 wird einteilig, vorzugsweise in einem Spritzgussprozess, hergestellt. Hierbei werden die Sicherungshalter 6 und/oder der zum Sicherungshalter 6 führende elektrische Leiter 8a und/oder der vom Sicherungshalter 6 wegführende elektrische Leiter 8b und/oder der zum Erdungssteckerstift 9a führende elektrische Leiter 8c in einer Gussform positioniert und anschließend in Gießmaterial, vorzugsweise in geeigneten elektrisch isolierenden Kunststoff, wie z.B. Polyamid (PA) oder Polybutylenterephthalat (PBTB), eingegossen.Also, the lid 3 is made in one piece, preferably in an injection molding process. Here, the fuse holder 6 and / or leading to the fuse holder 6 electrical conductor 8a and / or leading away from the fuse holder 6 electrical conductor 8b and / or the grounding pin 9a leading electrical conductor 8c are positioned in a mold and then in casting material, preferably in suitable electrically insulating plastic, such as Polyamide (PA) or polybutylene terephthalate (PBTB), cast in.

Nach der Herstellung des Deckels 3 wird der Deckel 3 auf die Grundplatte 2 derart aufgesetzt, dass die elektrische Sicherungseinrichtung 5 zumindest teilweise in die Aussparung 4 hineinragt. Vorzugsweise erfolgt eine stoffschlüssige Verbindung zwischen dem Deckel 3 und der Grundplatte 2, insbesondere durch Ultraschallschweißen oder andere Verfahren (z.B. Reibschweißen oder Kleben).After the lid 3 has been produced, the lid 3 is placed on the base plate 2 such that the electrical safety device 5 projects at least partially into the recess 4. Preferably, a material connection is made between the lid 3 and the base plate 2, in particular by ultrasonic welding or other methods (for example friction welding or gluing).

Die freien Enden des vom Sicherungshalter 6 wegführenden elektrischen Leiters 8b und des zum Erdungssteckerstift 9a führenden elektrischen Leiters 8c werden mit den entsprechenden Steckerstiften 9b, 9a verbunden. Beispielsweise kann diese Verbindung mittels einer Taumelnietung und/oder mittels Aussparungen und Vorsprüngen in den freien Enden der elektrischen Leiter 8b, 8c bzw. den jeweiligen Steckerstiften 9b, 9a erfolgen. Diese Verbindung kann vor oder nach der stoffschlüssigen Verbindung des Deckels 3 mit der Grundplatte 2 erfolgen oder auch zeitgleich dazu.The free ends of the electrical conductor 8b leading away from the fuse holder 6 and the electrical conductor 8c leading to the grounding pin 9a are connected to the corresponding connector pins 9b, 9a. For example, this connection can take place by means of a wobble riveting and / or by means of recesses and projections in the free ends of the electrical conductors 8b, 8c or the respective plug pins 9b, 9a. This connection can be made before or after the cohesive connection of the lid 3 with the base plate 2 or at the same time.

Obwohl dies in den dargestellten Ausführungsbeispielen nicht gezeigt ist, ist es auch möglich, die elektrische Sicherungseinrichtung 5 zumindest teilweise in die Grundplatte 2 einzugießen. Ebenfalls ist es möglich, sämtliche, zuvor genannte elektrischen Bauelemente in einer Gussform relativ zueinander zu positionieren und in einem einzigen Gussschritt einzugießen.Although not shown in the illustrated embodiments, it is also possible to at least partially inject the electrical safety device 5 into the base plate 2. It is also possible to position all the aforementioned electrical components in a mold relative to each other and to pour in a single casting step.

Um im Betrieb eine thermische Überlastung der Steckerbrücke 1 zu verhindern und die durch den elektrischen Widerstand der elektrischen Bauelemente, insbesondere den elektrischen Widerstand der elektrischen Sicherung 7, entstehenden Wärme besser abzuführen, ist es von Vorteil, die Steckerbrücke 1 mit zumindest einer Kühleinrichtung 13 zu versehen. Unter Bezugnahme auf die vorangegangenen Ausführungsbeispiele ist es möglich, die Kühleinrichtung 13 auf zumindest einer Seite des Deckels 3 vorzusehen. Vorzugsweise handelt es sich dabei um die griffseitige Seite des Deckels 3, d.h. die Seite, die der Sicherungskammer abgewandt ist.In order to prevent a thermal overload of the connector bridge 1 during operation and better dissipate the heat generated by the electrical resistance of the electrical components, in particular the electrical resistance of the electrical fuse 7, it is advantageous to provide the connector bridge 1 with at least one cooling device 13 , With reference to the preceding embodiments it is possible to provide the cooling device 13 on at least one side of the lid 3. Preferably, this is the handle side of the lid 3, ie the side facing away from the fuse chamber.

Ebenfalls ist es von Vorteil, zumindest einen im Deckel 3 integrierten, elektrischen Leiter 8a, 8b, 8c, d.h. den zum Sicherungshalter 6 führenden elektrischen Leiter 8a und/oder den vom Sicherungshalter 6 wegführenden elektrischen Leiter 8b und/oder den zum Erdungsstift 9a führenden elektrischen Leiter 8c, vorzugsweise innerhalb des Deckels 3, mit einer Kühleinrichtung 13 zu versehen.It is also advantageous to have at least one electrical conductor 8a, 8b, 8c integrated in the lid 3, i. the electrical conductor 8a leading to the fuse holder 6 and / or the electrical conductor 8b leading away from the fuse holder 6 and / or the electrical conductor 8c leading to the grounding pin 9a, preferably within the lid 3, are provided with a cooling device 13.

Ebenfalls ist es von Vorteil, auf zumindest einem Sicherungshalter 6, beispielsweise auf den im Deckel 3 integrierten Sockelbereich des Sicherungshalters 6, eine Kühleinrichtung 13 vorzusehen.It is also advantageous to provide a cooling device 13 on at least one fuse holder 6, for example on the base region of the fuse holder 6 integrated in the cover 3.

Alternativ oder zusätzlich ist es auch möglich, dass der direkt auf der Grundplatte 2 befestigte, elektrische Leiter 8d eine Kühleinrichtung 13 aufweist.Alternatively or additionally, it is also possible for the electrical conductor 8d fastened directly to the base plate 2 to have a cooling device 13.

Insbesondere ist es von Vorteil, wenn die Kühleinrichtung/-en 13 integral mit dem elektrischen Leiter 8a, 8b, 8c, 8d und/oder dem Deckel 3 ausgebildet ist/sind. Um die Wärme effizient abzuführen, ist die Kühleinrichtung 13 vorzugsweise als oberflächenvergrößernde Oberflächenstruktur ausgebildet. Beispielsweise kann die Kühleinrichtung 13 eine Vielzahl von regelmäßig angeordneten Vorsprüngen aufweisen. Diese Vorsprünge können im Wesentlichen pyramidenförmig oder kegelförmig ausgebildet sein, können jedoch auch eine lamellenartige Struktur in Form von Kühlrippen aufweisen.In particular, it is advantageous if the cooling device / s 13 is / are integrally formed with the electrical conductor 8a, 8b, 8c, 8d and / or the cover 3. In order to dissipate the heat efficiently, the cooling device 13 is preferably designed as a surface-enlarging surface structure. For example, the cooling device 13 may have a plurality of regularly arranged projections. These projections may be formed substantially pyramidal or conical, but may also have a lamellar structure in the form of cooling fins.

Bei der Herstellung der Steckerbrücke 1 ist es von Vorteil, wenn die Kühleinrichtung 13 integral mit dem Deckel 3 und/oder mit einem oder mehreren elektrischen Leitern 8a, 8b, 8c, 8d hergestellt wird. Die elektrischen Leiter 8a, 8b, 8c, 8d werden vorzugsweise aus einem Metallblech, beispielsweise einem Messingblech, hergestellt, indem sie aus dem Metallblech ausgestanzt werden.In the manufacture of the connector bridge 1, it is advantageous if the cooling device 13 is produced integrally with the cover 3 and / or with one or more electrical conductors 8a, 8b, 8c, 8d. The electrical conductors 8a, 8b, 8c, 8d are preferably made of a metal sheet, such as a brass sheet, by being punched out of the sheet metal.

Wird der elektrische Leiter 8a, 8b, 8c, 8d aus dem Metallblech ausgestanzt, ist es insbesondere vorteilhaft, die Kühleinrichtung 13 zeitgleich mit dem Stanzschritt auf der Oberfläche des Metallblechs auszubilden. Jedoch ist es auch möglich, die Kühleinrichtung 13 bereits vor dem Stanzvorgang beispielsweise durch einen Prägeschritt auf das Metallblech aufzubringen oder den ausgestanzten, elektrischen Leiter 8a, 8b, 8c, 8d im Nachhinein mit der Kühleinrichtung 13 zu versehen. Da die elektrischen Leiter 8a, 8b, 8c, 8d für die Kontaktierung innerhalb der Steckerbrücke 1 vorzugsweise umzubiegen sind, um sie optimal an die räumlichen Gegebenheiten innerhalb der Steckerbrücke 1 anzupassen, kann die Kühleinrichtung 13 zeitgleich mit dem Umformschritt durch einen Prägeschritt ausgebildet werden.If the electrical conductor 8a, 8b, 8c, 8d punched out of the metal sheet, it is particularly advantageous to form the cooling device 13 at the same time as the punching step on the surface of the metal sheet. However, it is also possible, the cooling device 13 already before the punching process, for example by an embossing step to apply the metal sheet or to provide the punched-out, electrical conductor 8a, 8b, 8c, 8d in retrospect with the cooling device 13. Since the electrical conductors 8a, 8b, 8c, 8d for the contacting within the connector bridge 1 are preferably bend over in order to adapt them optimally to the spatial conditions within the connector bridge 1, the cooling device 13 can be formed simultaneously with the forming step by an embossing step.

Beim Deckel 3 ist es möglich, die Kühleinrichtung 13 als oberflächenvergrößernde Oberflächenstruktur durch entsprechende Gestaltung der Spritzgussform direkt beim Spritzgießen zu erzeugen.With the lid 3, it is possible to produce the cooling device 13 as a surface-enlarging surface structure by appropriate design of the injection mold directly during injection molding.

Obwohl in den Figuren 1a bis 4 die Kühleinrichtung 13 in Kombination mit den im Deckel 3 integrierten, elektrischen Bauelemente dargestellt ist, sind diese beiden Aspekte als unabhängig voneinander zu betrachten. Insbesondere ist es auch möglich, Steckerbrücken 1 mit einer oder mehreren Kühleinrichtungen 13 der vorgenannten Art herzustellen, jedoch ohne dass die elektrischen (leitenden) Bauelemente in die Grundplatte 2 und/oder in den Deckel 3 eingegossen sind.Although in the FIGS. 1a to 4 the cooling device 13 is shown in combination with the integrated in the cover 3, electrical components, these two aspects are considered to be independent of each other.
