Bei den bekannten Steckverbindungsvorrichtungen müssen die Stecker- und Buchsenelemente an den ihnen zugeordneten elektrischen Leitungen elektrisch kontaktierend festgelegt werden, wodurch zusätzliche Kontaktstellen entstehen, die insbesondere unter erschwerten Betriebsbedingungen wie beispielsweise Vibrationen oder aggressiven Atmosphären eine potentielle Störungsquelle darstellen.

In addition, constructive measures must be taken so that both the plug and the socket element, in particular in the region of the contact points are safe to touch.

Der Erfindung liegt das Problem zugrunde, eine Vorrichtung zum Steckverbinden einer ersten elektrischen Leitung mit einer zweiten elektrischen Leitung mit einem der ersten Leitung zugeordneten Steckerelement und einem der zweiten Leitung zugeordneten Buchsenelement bereitzustellen, mit der auf einer Platine angeordnete elektrische und/oder elektronische Bauteile kontaktiert werden und dabei möglichst wenige störanfällige Kontaktstellen aufweist und dabei den Berührschutz trotz einfacher Herstellung gewährleistet.The invention is based on the problem of providing a device for plugging a first electrical line with a second electrical line with a plug element assigned to the first line and a socket element associated with the second line, with which electrical and / or electronic components arranged on a circuit board are contacted and thereby has as few interference-prone contact points and thereby ensures contact protection despite simple production.
Das Problem ist durch die in den unabhängigen Ansprüchen bestimmte Vorrichtung gelöst. Besondere Ausführungsarten der Erfindung sind in den Unteransprüchen bestimmt.The problem is solved by the device defined in the independent claims. Particular embodiments of the invention are defined in the subclaims.
Das Buchsenelement weist einen die zweite Leitung bildenden Blechstreifen auf, der an seinem Ende quer zu seiner Längsrichtung unter Bildung der Stiftaufnahme derart geformt und insbesondere gebogen ist, daß der Steckerstift in Längsrichtung des Blechstreifens in die Stiftaufnahme einsteckbar ist. Die zweite Leitung und das Buchsenelement sind einstückig ausgeführt, und es entfällt eine Kontaktstelle zwischen der zweiten Leitung und dem Buchsenelement. Die Stiftaufnahme weist in einem mit der Längsachse des Blechstreifens einen rechten Winkel einschließenden Querschnitt eine im wesentlichen mit dem entsprechenden Querschnitt des Steckerstiftes übereinstimmende Form auf. Der Steckerstift ist beispielsweise kreiszylindrisch und ebenso wie die Stiftaufnahme für eine Stromtragfähigkeit von 1 bis 1000 A, vorzugsweise 50 bis 200 A ausgelegt. Der Blechstreifen ist vorzugsweise aus Kupfer oder einer Kupferlegierung gefertigt und weist vorzugsweise eine Blechstärke zwischen 0,5 und 2 mm auf.The bushing element has a metal strip forming the second line, which is shaped and in particular bent at its end transversely to its longitudinal direction to form the pin receptacle, in that the plug pin can be inserted into the pin receptacle in the longitudinal direction of the metal strip. The second line and the socket element are made in one piece, and there is no contact point between the second line and the socket element. The pin receptacle has, in a cross section enclosing a right angle with the longitudinal axis of the sheet metal strip, a shape substantially matching the corresponding cross section of the plug pin. The pin is, for example, circular cylindrical and, like the pin holder for a current carrying capacity of 1 to 1000 A, preferably 50 to 200 A designed. The metal strip is preferably made of copper or a copper alloy and preferably has a plate thickness between 0.5 and 2 mm.
Durch die Bildung der Stiftaufnahme durch Biegung des Blechstreifens quer zu seiner Längsrichtung weist die Stiftaufnahme eine hohe Biegesteifigkeit insbesondere in Einführrichtung des Steckerstiftes auf. Die Längsrichtung des Blechstreifens ist im wesentlichen parallel zur Einführrichtung des Steckerstiftes und der Blechstreifen ist im Bereich der Stiftaufnahme zumindest teilweise um die Mittelachse der Vorrichtung herum gebogen. Dadurch ist die Ausbildung des Buchsenelementes als an einem Gehäuse festgelegte oder einstückig von diesem ausgebildete Einbaubuchse und der für den Blechstreifen bzw. die zweite Leitung vorzusehende Durchbruch an dem Gehäuse einfach realisierbar.Due to the formation of the pin receptacle by bending the metal strip transversely to its longitudinal direction, the pin receptacle has a high flexural rigidity, in particular in the insertion direction of the plug pin. The longitudinal direction of the metal strip is substantially parallel to the insertion direction of the plug pin and the metal strip is at least partially bent in the region of the pin receptacle around the central axis of the device. As a result, the design of the socket element as fixed to a housing or integrally formed by this mounting socket and to be provided for the metal strip or the second line breakthrough on the housing is easy to implement.
Erfindungsgemäß bildet der Blechstreifen außerhalb des Buchsen- oder Steckerelements einstückig eine Platine aus, auf der die Bauelemente einer elektrischen oder elektronischen Einrichtung angeordnet sind, beispielsweise einer Umrichterelektronik für eine Motor- und/oder Generatoreinrichtung. Dadurch entfallen weitere Kontakt- und Verbindungsstellen und die Betriebssicherheit ist bei reduzierten Herstellungs- und Montagekosten erhöht. Es können auch mehrere jeweils eine Stiftaufnahme für ein Buchsenelement ausbildende Blechstreifen je eine Lage einer insgesamt mehrschichtigen Platine ausbilden, wobei die einzelnen Lagen gegeneinander elektrisch isoliert sind. Die auf der Platine aufgebrachten elektrischen und/oder elektronischen Bauelemente können mit einer oder mehreren der Lagen und damit mit einer oder mehreren der Stiftaufnahmen elektrisch verbunden sein.According to the invention, the sheet-metal strip outside of the socket or plug element integrally forms a board on which the components of an electrical or electronic device are arranged, for example a converter electronics for a motor and / or generator device. This eliminates further contact and connection points and the reliability is reduced Increased manufacturing and assembly costs. It is also possible for a plurality of sheet metal strips each forming a pin receptacle for a socket element to form one layer of an overall multi-layer board, wherein the individual layers are electrically insulated from one another. The applied on the board electrical and / or electronic components may be electrically connected to one or more of the layers and thus with one or more of the pin recordings.
Dadurch, daß das Buchsenelement aus zwei oder mehreren Blechstreifen gebildet ist, ist die Kontaktsicherheit und die Stromtragfähigkeit der Stiftaufnahme erhöht. Der Biegeradius der einzelnen Blechstreifen ist vorzugsweise im wesentlichen identisch und insbesondere kleiner als der Radius des Steckerstiftes. Dadurch ergeben sich vorteilhaft mindestens zwei Kontaktstellen bzw. -linien je Blechstreifen. Darüber hinaus kann der Blechstreifen im Bereich der Stiftaufnahme mehrere vorzugsweise einstückig angeformte punkt-, linien- oder flächenartige und den Steckerstift kontaktierende Kontaktstellen aufweisen.Characterized in that the female member is formed of two or more metal strips, the contact reliability and current carrying capacity of the pin receptacle is increased. The bending radius of the individual metal strips is preferably substantially identical and in particular smaller than the radius of the plug pin. This results in advantageous at least two contact points or lines per sheet metal strip. In addition, the sheet-metal strip in the region of the pin receptacle may have a plurality of preferably point-shaped, line-shaped or area-like contact points which are integrally formed and which contact the plug pin.
Dadurch, daß die mindestens zwei Blechstreifen einstückig ausgebildet sind, entfällt eine grundsätzlich störanfällige elektrische Verbindungsstelle. Alternativ zur einstückigen Ausbildung der mindestens zwei Blechstreifen können diese vorzugsweise außerhalb des Buchsenbereiches mechanisch und gegebenenfalls auch elektrisch fest miteinander verbunden sein. Vorzugsweise ist diese Verbindung unlösbar, beispielsweise durch Vernieten, Verlöten, Schweißen, insbesondere Punktschweißen, oder durch Umbördeln von ausgebildeten Blechlappen. Selbstverständlich ist auch ein Verschrauben, Verhaken oder Verrasten der Blechstreifen möglich. Dadurch ist ein elektrisches Verbinden von beispielsweise zwei Teilleitungen der zweiten Leitung durch die Steckverbindungsvorrichtung möglich. Soweit die Verbindungsstelle der mindestens zwei Blechstreifen lediglich eine mechanische Verbindung bereitstellt, ergibt sich eine elektrische Verbindung der mindestens zwei Blechstreifen beim Einstecken des Steckerelements.The fact that the at least two metal strips are integrally formed eliminates a fundamentally fault-prone electrical connection point. As an alternative to the integral formation of the at least two sheet-metal strips, they can preferably be connected to one another mechanically outside of the bushing region and optionally also electrically. Preferably, this connection is insoluble, for example by riveting, soldering, welding, in particular spot welding, or by crimping trained sheet metal tabs. Of course, a screwing, hooking or locking the metal strips is possible. As a result, an electrical connection of, for example, two sub-lines of the second line through the connector device is possible. As far as the junction of the at least two metal strips merely provides a mechanical connection, results in an electrical connection of the at least two metal strips during insertion of the male member.
Dadurch, daß der bzw. die Blechstreifen im Bereich der Stiftaufnahme von einem kraftspeichernden Sicherungselement umfaßt ist bzw. sind, beispielsweise von einem oder mehreren eine Federkraft in radialer Richtung auf die Blechstreifen ausübenden Klemmring, ist die Kontaktsicherheit und Stromtragfähigkeit der Stiftaufnahme weiter erhöht.Due to the fact that the sheet metal strip or strips in the region of the pin receptacle is or are comprised of a force-storing securing element, for example one or more clamping rings exerting a spring force in the radial direction on the sheet metal strips, the contact reliability and current carrying capacity of the pin receptacle is further increased.
Dadurch, daß die Stiftaufnahme in einem vorzugsweise elektrisch isolierenden Buchsengehäuse angeordnet ist, welches die Stiftaufnahme endseitig unter Belassung einer Öffnung für den Durchtritt des Steckerstiftes übergreift, ist das Buchsenelement berührungssicher. Die Öffnung für den Durchtritt des Steckerstiftes ist dabei vorzugsweise nur geringfügig größer als der Steckerstift und in ihrer Form an die Form des Steckerstiftes angepaßt. Die Stiftaufnahme ist innerhalb des Buchsenelementes so angeordnet und insbesondere gegenüber der Öffnung so weit zurückversetzt, daß ein nach den Sicherheitsvorschriften vorgegebener Prüffinger beim Einlegen in die Öffnung nicht in Kontakt mit der Stiftaufnahme kommt.Characterized in that the pin receptacle is arranged in a preferably electrically insulating socket housing, which engages over the pin receiving end, leaving an opening for the passage of the plug pin, the socket element is safe to touch. The opening for the passage of the plug pin is preferably only slightly larger than the pin and adapted in shape to the shape of the plug pin. The pin receptacle is arranged within the socket element and so far set back so far in particular with respect to the opening that a test finger given according to the safety regulations does not come into contact with the pin receptacle when it is inserted into the opening.
Dadurch, daß das Buchsengehäuse mit dem Steckerelement zusammenwirkende Rastmittel aufweist, ist die Steckverbindung einfach und insbesondere ohne ein spezielles Montagewerkzeug herstellbar, wodurch die Gefahr des unbeabsichtigten Berührens des Steckerstiftes und/oder der Stiftaufnahme ausgeschlossen ist.Characterized in that the socket housing having cooperating with the plug element latching means, the plug connection is simple and in particular without a special assembly tool produced, whereby the risk of inadvertent contact of the plug pin and / or the pin receptacle is excluded.
Dadurch, daß der Steckerstift in einem ihn in Steckrichtung überragenden Steckergehäuse derart angeordnet ist, daß ein nach den Sicherheitsvorschriften vorgeschriebener Prüffinger beim Einlegen in die Steckeröffnung nicht in Kontakt mit dem Steckerstift kommt, wird der Berührschutz auch hinsichtlich des Steckerelementes der Steckverbindungsvorrichtung gewährleistet. Ein zusätzlicher Berührschutz wird dadurch erreicht, daß der Steckerstift einen elektrisch isolierenden Endabschnitt aufweist, der vorzugsweise durch ein endseitig an dem Steckerstift angebrachtes elektrisch isolierendes Abschlußelement realisiert ist. Durch endseitiges konisches oder sphärisches Ausbilden des Abschlußelements ist sowohl der Berührschutz erhöht als auch das Einstecken des Steckerstiftes in die Stiftaufnahme vereinfacht.Due to the fact that the plug pin is arranged in a plug housing projecting beyond it in the insertion direction such that a test finger prescribed according to the safety regulations does not come into contact with the plug pin when being inserted into the plug opening, the contact protection is also ensured with regard to the plug element of the plug connection device. An additional contact protection is achieved in that the plug pin has an electrically insulating end portion, which is preferably realized by an end attached to the plug pin electrically insulating closure element. By end-side conical or spherical formation of the terminating element, both the contact protection is increased and the insertion of the pin into the pin receptacle simplified.
