Mehrpolige elektrische Steckverbindung Multipole electrical connector
BESCHREIBUNGDESCRIPTION
Die Erfindung betrifft eine mehrpolige elektrische Steckverbindung mit den Merkmalen des Oberbegriffes des Patentanspruchs 1The invention relates to a multi-pole electrical connector with the features of the preamble of claim 1
Aus US 3,398,260 ist ein kabelloses elektπsches Bügeleisen bekannt, das eine Steckverbindung aufweist, die einen in einer Basiseinheit angeordneten Basisstecker sowie einen am Bügeleisen angeordneten Gegenstecker aufweist. Die Stecker sind so gestaltet, daß Basis- und Gegenstecker in im wesentlichen jeder relativen Drehwinkelposition zusammensteckbar und/oder in zusammengefugtem Zustand gegeneinander verdrehbar sind.From US 3,398,260 a wireless electric iron is known which has a plug connection which has a base plug arranged in a base unit and a mating connector arranged on the iron. The plugs are designed in such a way that the base and mating plugs can be plugged together in essentially any relative rotational angle position and / or can be rotated relative to one another in the assembled state.
Aus PCT/GB94/02010 sowie EP 0 658 288 sind kabellose elektπsche Wasserkocher bekannt, die einen an einer Basiseinheit angeordneten Basisstecker sowie einen am Boden des Wassertopfes angeordneten Gegenstecker aufweisen. Die Kontakte der beiden Stecker kontaktieren in aufgesetztem Zustand des Topfes auf die Basiseinheit miteinander. Der Wassertopf ist auf die Basis im wesentlichen in jeder relativen Drehwinkelposition aufsetzbar und/oder in zusammengefügtem Zustand dagegen verdrehbar.From PCT / GB94 / 02010 and EP 0 658 288 wireless electric kettles are known which have a base plug arranged on a base unit and a mating plug arranged on the bottom of the water pot. The contacts of the two plugs make contact with each other when the pot is placed on the base unit. The water pot can be placed on the base essentially in any relative angular position and / or rotated in the assembled state.
Die bekannten aus Basisstecker und Gegenstecker gebildeten Steckverbindungen sind insofern nachteilig, als sie relativ kompliziert aufgebaut sind und aufgrund der ineinander liegenden Anordnung ihrer Kontakte einen relativ großen Durchmesser haben.The known plug connections formed from basic plugs and mating plugs are disadvantageous insofar as they are constructed in a relatively complicated manner and have a relatively large diameter due to the internal arrangement of their contacts.
Der Erfindung hegt die Aufgabe zugrunde, eine mehrpolige elektπsche Steckverbindung mit den Merkmalen des Oberbegriffes des Patentanspruchs 1 derart auszubilden, daß sie einfach herstellbar und, was ihre Kontakteigenschaften anbelangt, elektrisch sicher und robust ausgebildet ist, sowie eine einfache Aufsetzbarkeit des Gerätes auf seine Basiseinheit ermöglicht.The invention has for its object to provide a multi-pole electrical connector with the features of the preamble of claim 1 in such a way that it is easy to manufacture and, as far as its contact properties are concerned, is electrically safe and robust, and enables the device to be easily fitted onto its base unit .
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst, vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen 2 - 19. Als Kern der Erfindung wird es angesehen, den Gegenstecker mit einem im wesentlichen aus Isoliermateπal ausgebildeten Kontaktfinger zu versehen, an welchem axial beabstandet und übereinanderhegend die als Kontaktπnge oder Kontaktπngflächen ausgebildeten Kontaktelemente angeordnet sind. Die Gegenkontakte, die in einer Öffnung des Basissteckers angeordnet sind, beaufschlagen die Oberflächen der Ringkontakte mit radial nach innen gerichtetem Kontaktdruck.This object is achieved by the characterizing features of patent claim 1; advantageous developments of the invention result from subclaims 2-19. It is considered to be the essence of the invention to provide the mating connector with a contact finger essentially made of insulating material, on which the contact elements designed as contact lengths or contact surfaces are arranged axially spaced and one above the other. The counter contacts, which are arranged in an opening of the base connector, act on the surfaces of the ring contacts with radially inward contact pressure.
Grundsätzlich ist es mit Vorteil möglich, an dem Kontaktfinger axial beabstandet die drei Kontakte für Masse. Phase und Nulleiter übereinander anzuordnen.In principle, it is advantageously possible for the three contacts for ground to be axially spaced apart on the contact finger. Arrange phase and neutral on top of each other.
Wenn im Zusammenhang mit der Erfindung von Kontaktringen gesprochen wird, so sind damit alle ringartigen ubereinanderliegenden Kontaktformen umfaßt, auch Ringsegmente oder Ringabschnitte. Es muß nur sichergestellt sein, daß durch entsprechende Gegenkontakte die jeweiligen Masse-, Phase- und Nulleiter-Kontaktabschnitte oder -segmente oder -ringe immer Kontakt haben, wenn die beiden Stecker der Steckverbindung vollständig zusammengefügt sind und/oder gegeneinander verdreht werden.If one speaks in connection with the invention of contact rings, then all ring-like superimposed contact forms are included, including ring segments or ring sections. It only has to be ensured that the corresponding ground, phase and neutral contact sections or segments or rings always have contact by means of corresponding counter-contacts if the two plugs of the plug connection are completely assembled and / or are rotated relative to one another.
Beispielsweise ist es möglich, in jeder Kontakthöhe bezogen auf den Kontaktfinger zwei Gegenkontakte anzuordnen und einen Kontaktπng z.B. mehrteilig auszubilden, wenn dies aus konstruktiven Gründen vorteilhaft erscheint.For example, it is possible to arrange two counter-contacts at each contact height based on the contact finger and to create a contact e.g. train in several parts if this appears to be advantageous for design reasons
Die Oberflächen der Kontaktringe sind auf einer gemeinsamen Zylindermantelfläche angeordnet oder weisen zumindest im wesentlichen den gleichen Maximaldurchmesser auf. Die erste Alternative dieses Kennzeichens des Patentanspruchs 3 sieht vor, daß die Oberflächen der Kontaktringe zylindermantelförmig ausgebildet sind. Es ist aber auch möglich, den Oberflächen der ubereinanderliegenden Kontakte eine ballige Form oder eine konkave Form zu geben, wenn dies aus technischen Gründen vorteilhaft erscheint. In diesem Falle sollen dann aber die wirksamen Durchmesser, insbesondere Maximaldurchmesser übereinstimmen.The surfaces of the contact rings are arranged on a common cylindrical surface or at least have essentially the same maximum diameter. The first alternative of this characterizing part of claim 3 provides that the surfaces of the contact rings are cylindrical in shape. However, it is also possible to give the surfaces of the superimposed contacts a spherical shape or a concave shape if this appears advantageous for technical reasons. In this case, however, the effective diameters, in particular maximum diameters, should match.
Besonders vorteilhaft ist es, wenn der Außendurchmesser der Kontaktringe etwas größer als der Außendurchmesser der zwischen den Kontaktπngen verlaufenden, etwas eingeschnürten Isoher- bereiche des Kontaktfingers ist. Dadurch erhöhen sich die Kriechstrecken. Um die Berührsicherheit zu verbessern und dem Kontaktfinger einen stabilen Durchmesser geben zu können, hat der Kontaktfinger eine in Axialrichtung verlaufende Zentralausnehmung, in welche in aufgesetztem Zustand ein Zentralzapfen des Basissteckers eintaucht, der sich in dem Basissteckergehäuse zentral innerhalb der Gegenkontakte erstreckt. Dieser Zentralzapfen kann bezogen auf den Kontaktfinger eine Fuhrungsfunktion übernehmen und wäre dann als Führungszapfen zu bezeichnen. Es ist aber auch denkbar, den Zentralzapfen nur dazu vorzusehen, den-zu- ganglichen Querschnitt bzw. die lichte Weite der Einstecköffnung im Basissteckergehäuse soweit zu verkleinern, daß die vorgeschriebene Berührsicherheit der Kontakte sichergestellt ist.It is particularly advantageous if the outer diameter of the contact rings is somewhat larger than the outer diameter of the somewhat constricted iso-regions of the contact finger running between the contact rings. This increases the creepage distances. In order to improve the safety against contact and to be able to give the contact finger a stable diameter, the contact finger has a central recess running in the axial direction, into which, when fitted, a central pin of the basic plug is immersed, which extends centrally in the basic plug housing within the counter contacts. This central pin can assume a guiding function in relation to the contact finger and would then be referred to as a guide pin. However, it is also conceivable to provide the central pin only to reduce the accessible cross-section or the inside width of the insertion opening in the basic connector housing to such an extent that the prescribed contact safety of the contacts is ensured.
Die lichte Weite des das freie Ende des Zentralzapfens umgebenden Ringspaltes sollte dabei kleiner als 3 mm sein und das freie Ende des Zentralzapfens in der Ebene der Einstecköffnung angeordnet sein.The clear width of the annular gap surrounding the free end of the central pin should be less than 3 mm and the free end of the central pin should be arranged in the plane of the insertion opening.
Ferner ist es der Berührsicherheit zuträglich, wenn der mit Masse verbundene Gegenkontakt unmittelbar unter der Einstecköffnung des Basissteckergehäuse angeordnet ist.It is also conducive to contact safety if the mating contact connected to ground is arranged directly under the insertion opening of the basic connector housing.
Die weiteren Unteransprüche betreffen vorteilhafte Anordnungen der Gegenkontakte im Basissteckergehäuse.The further subclaims relate to advantageous arrangements of the mating contacts in the basic connector housing.
Patentanspruch 1 1 lehrt eine besonders vorteilhafte Ausführungsform der Kontaktanordnung und -Öffnung im Basissteckergehäuse. Es ist nämlich eine in Richtung zur Einstecköffnung hin federbelastete axial verschiebbare Kulisse vorgesehen, die durch das untere Ende des in die Kon- taktöffnung hineingleitenden Kontaktfingers beaufschlagt werden kann. Wird der Gegenstecker aus dem Basisstecker herausgezogen, folgt die axial verschiebbare Kulisse eine gewisse Weg""- strecke dem freien Ende des Kontaktfingers und hebt dabei die Gegenkontakte von den Oberflächen der zugeordneten Ringkontakte des Kontaktfingers ab. Dadurch wird ein sehr definiertes Schaltverhalten sichergestellt. Zunächst gleiten die Gegenkontakte auf den Oberflächen der Ringkontakte, dann kommt es zu der radialen Abhebebewegung, so daß sich besonders vorteilhafte Kontaktreinigungs- und Schaltverhältnisse innerhalb der Steckverbindung ergeben.Claim 1 1 teaches a particularly advantageous embodiment of the contact arrangement and opening in the basic connector housing. This is because an axially displaceable link spring-loaded in the direction of the insertion opening is provided, which can be acted upon by the lower end of the contact finger sliding into the contact opening. If the mating connector is pulled out of the basic connector, the axially displaceable link follows a certain path "" - extend the free end of the contact finger and thereby lifts the mating contacts from the surfaces of the associated ring contacts of the contact finger. This ensures a very defined switching behavior. First, the counter contacts slide on the surfaces of the ring contacts, then there is the radial lifting movement, so that there are particularly advantageous contact cleaning and switching conditions within the connector.
Ein Gleiten der Gegenkontakte auf den zwischen den Ringkontakten liegenden Isolierbereichen wird verhindert. Gleichzeitig wird ein Kurzschluß zwischen stromführenden Ringkontakten und den Geeenkontakten über die Heizunς verhindert. Die Erfindung ist anhand eines vorteilhaften Ausführungsbeispiels in den Zeichnungsfiguren naher erläutert. Diese zeigenA sliding of the counter contacts on the insulating areas lying between the ring contacts is prevented. At the same time, a short circuit between current-carrying ring contacts and the Gee contacts via the heater is prevented. The invention is explained in more detail using an advantageous embodiment in the drawing figures. These show

Die mehrpolige elektπsche Steckverbindung 1 weist einen in einer Basiseinheit 2 angeordneten Basisstecker 3 sowie einen Gegenstecker 4 auf, der beispielsweise am Boden 5 eines Haushaltsgerätes, insbesondere eines Wassertopfes, angebracht ist und Kontaktelemente aufweist, die in auf die Basiseinheit 2 aufgesetzten Zustand des Haushaltsgerätes mit in einem Steckverbindungsgehause 6 angeordneten Gegenkontakten 7 des Basissteckers 3 zusammenwirken. Der Gegenstecker 4 umfaßt einen aus Isoliermateπal ausgebildeten Kontaktfinger 8, an welchem axial beabstandet und übereinanderhegend die als Kontaktringe 9 ausgebildeten Kontaktelemente angeordnet sind. Diese wirken in zusammengefügtem Zustand (s. Fig. 3) mit den in Einsteckπch- tung 10 ubereinanderliegenden Gegenkontaktelementen 7 des Basissteckers 3 zusammen. Die Kontaktπnge 9 werden dabei von den Gegenkontaktelementen 7 mit radial nach innen gerichteten Kontaktdruck beaufschlagt.The multi-pole electrical connector 1 has a base connector 3 arranged in a base unit 2 and a mating connector 4, which is attached, for example, to the bottom 5 of a household appliance, in particular a water pot, and has contact elements which, when placed on the base unit 2 of the household appliance, have in a connector housing 6 arranged counter contacts 7 of the base connector 3 cooperate. The mating connector 4 comprises a contact finger 8 made of insulating material, on which the contact elements 9 designed as contact rings 9 are axially spaced and one above the other. In the assembled state (see FIG. 3), these interact with the mating contact elements 7 of the base plug 3, one above the other in the insertion 10. The Kontaktπnge 9 are acted upon by the counter-contact elements 7 with radially inwardly directed contact pressure.
Der Kontaktfinger 8 weist bei dem dargestellten Ausführungsbeispiel drei axial beabstandete Kontaktringe 9 auf. Die Oberflächen dieser Kontaktπnge 9 liegen beim Ausführungsbeispiel auf einer gemeinsamen Zylindermantelfläche.In the exemplary embodiment shown, the contact finger 8 has three axially spaced contact rings 9. In the exemplary embodiment, the surfaces of these contact lengths 9 lie on a common cylindrical surface.
In einer modifizierten Ausfuhrungsform ist es auch möglich, daß der Außendurchmesser der Kontaktπnge 9 etwas größer als der Außendurchmesser der zwischen den Kontaktπngen 9 verlaufenden etwas eingeschnürten Isoherbereiche 1 1 des Kontaktfingers 8 ist.In a modified embodiment it is also possible for the outer diameter of the contact pin 9 to be somewhat larger than the outer diameter of the somewhat constricted isothermal areas 11 of the contact finger 8 running between the contact pin 9.
Wie in Fig 2 deutlich zu sehen ist, weist der Kontaktfinger 8 eine in Einsteckrichtung 10 verlaufende Zentralausnehmung 12 auf, in welche in aufgesetztem Zustand ein Zentralzapfen 13 des Basissteckers 3 eintaucht, der sich in dem Steckverbindungsgehause 6 zentral innerhalb der Gegenkontakte 7 erstreckt Das freie Ende 20 des Zentralzapfens 13 ist von einem Ringspalt 21 umgeben, dessen lichte Weite 22 < 3 mm ist. Das freie Ende 20 des Zentralzapfens 13 ist dabei etwa in der Ebene durch den Ringspalt 21 gebildeten Einstecköffnung 23 des Steckverbindungsgehäuses 6 angeordnet.As can be clearly seen in FIG. 2, the contact finger 8 has a central recess 12 which extends in the insertion direction 10 and into which a central pin 13 of the basic plug 3, which extends centrally in the plug housing 6 within the mating contacts 7, is immersed The free end 20 of the central pin 13 is surrounded by an annular gap 21, the clear width 22 <3 mm. The free end 20 of the central pin 13 is arranged approximately in the plane formed by the annular gap 21 insertion opening 23 of the connector housing 6.
Der mit Masse verbundene Gegenkontakt 7a ist unmittelbar unter der Einstecköffnung 23 angeordnetThe mating contact 7a connected to ground is arranged directly under the insertion opening 23
In Fig. 1 ist zu sehen, daß die Gegenkontakte 7 radial etwa gleichverteilt im Steckverbindungsgehause 6 angeordnet sind. Diese Darstellung findet sich nicht in den Fig. 2 und 3 wieder. Dort sind die Gegenkontakte der Einfachheit halber in der Schnittebene dargestellt.In Fig. 1 it can be seen that the counter contacts 7 are arranged radially approximately evenly distributed in the connector housing 6. This representation is not found in FIGS. 2 and 3. For the sake of simplicity, the mating contacts are shown there in the sectional plane.

Im Bereich des Festendes 40 des Zentralzapfens 13 ist eine in Richtung zur Emstecköffnung 23 hin federbelastete, durch das untere Ende 41 des Kontaktfingers 8 beaufschlagbare, axial verschiebbare Kulisse 42 angeordnet, die beim Herausziehen des Gegensteckers 4 aus dem Basisstecker 3 zumindest die phaseleitenden und nulleitenden Kontakte 7b, 7c infolge einer zur Einstecköffnung 23 gerichteten Axialbewegung radial von den Oberflächen der zugeordneten Ringkontakte 9 des Kontaktfingers 8 abhebt. Die Kulisse 42 ist dabei axial auf dem Zentralzapfen 13 geführtArranged in the area of the fixed end 40 of the central pin 13 is an axially displaceable link 42 which is spring-loaded in the direction of the insertion opening 23 and can be acted upon by the lower end 41 of the contact finger 8 and which at least has the phase-conducting and non-conducting contacts when the mating connector 4 is pulled out of the base connector 3 7b, 7c, as a result of an axial movement directed towards the insertion opening 23, lifts radially from the surfaces of the associated ring contacts 9 of the contact finger 8. The link 42 is axially guided on the central pin 13
