Description

Die Erfindung betrifft einen Steckverbinder für ein Elektrofahrrad. Der Steckverbinder umfasst eine Mehrzahl von elektrischen Steckkontakten und eine Steckerwand, die die Steckkontakte in Umfangsrichtung umgibt.The invention relates to a connector for an electric bicycle. The connector comprises a plurality of electrical plug contacts and a connector wall which surrounds the plug contacts in the circumferential direction.

Fahrräder können unterstützende elektrische Motoren aufweisen, um den Fahrradfahrer z.B. bei Steigungen oder beim Beschleunigen zu entlasten. Die Motoren solcher Elektrofahrräder können am Tretlager angeordnet sein und Sensoren aufweisen, die das Drehmoment am Tretlager und die Geschwindigkeit des Fahrrads erfassen. Ein Schaltkreis auf einer Platine bestimmt aus einem Vergleich der Messdaten, ob der Motor das Elektrofahrrad beschleunigen muss, um dem Fahrer zu entlasten bzw. um eine vorbestimmte Geschwindigkeit zu halten. Bei Bremsmanövern können diese Motoren bei der Rekuperation als Generatoren mitwirken. Die umgewandelte Energie kann in externe elektrische Speicher eingespeist und zu einem späteren Zeitpunkt wieder abgerufen werden. Weiter können die Motoren als Energiequelle für Peripheriegeräte wie Beleuchtung, Geschwindigkeitsanzeige usw. dienen.Bicycles may have assisting electric motors to provide the cyclist with e.g. to relieve on inclines or when accelerating. The motors of such electric bicycles can be arranged on the bottom bracket and have sensors that detect the torque at the bottom bracket and the speed of the bicycle. A circuit on a board determines from a comparison of the measurement data whether the motor has to accelerate the electric bicycle to relieve the driver or to keep a predetermined speed. During braking maneuvers, these motors can participate in the recuperation as generators. The converted energy can be fed into external electrical storage and recalled at a later time. Further, the motors can serve as an energy source for peripheral devices such as lighting, speedometer, etc.

Dazu benötigen die Motoren elektrische Leitungen zu den Energiespeichern und den Peripheriegeräten, um Energie oder Signale zu übermitteln. Da die Peripheriegeräte in der Regel nicht am Motor selbst sondern an einer anderen Stelle am Rahmen des Fahrrads angebracht sind, werden zur Verbindung Kabel benutzt, die über elektrische Steckverbinder mit entsprechenden Anschlüssen verbunden werden.For this, the motors require electrical leads to the energy storage devices and the peripherals to transmit energy or signals. Since the peripherals are usually not attached to the engine itself but at a different location on the frame of the bicycle, are used to connect cables used, which are connected via electrical connectors with appropriate connections.

Bekannt sind elektrische Anschlüsse, bei denen das Kabel durch das Motorgehäuse hindurchgeführt ist und bei denen direkt am Motorgehäuse keine Möglichkeit besteht, die elektrische Verbindung zu trennen. Eine elektrische Steckverbindung gibt es erst in einigem Abstand von dem Motorgehäuse. Häufig ist die elektrische Steckverbindung in der Mitte eines Kabels angeordnet, also als sogenannte fliegende Steckverbindung ausgebildet. Wünschenswert ist eine fest am Motorgehäuse angeordnete elektrische Steckverbindung. Allerdings ist im Bereich des Tretlagers nur wenig Platz. Außerdem ist die elektrische Steckverbindung dort Spritzwasser ausgesetzt.Are known electrical connections in which the cable is passed through the motor housing and in which directly on the motor housing is no way to disconnect the electrical connection. An electrical connector is only available at some distance from the motor housing. Often the electrical plug-in connection is arranged in the middle of a cable, that is designed as a so-called flying plug connection. Desirable is a fixedly arranged on the motor housing electrical connector. However, there is only limited space in the area of the bottom bracket. In addition, the electrical connector is exposed there spray water.

Aufgabe der Erfindung ist es, eine zuverlässige elektrische Steckverbindung zu schaffen, die zur Verwendung bei einem am Tretlager angeordneten Motor eines Elektrofahrrads geeignet ist. Ausgehend vom genannten Stand der Technik wird die Aufgabe gelöst durch die Merkmale der unabhängigen Ansprüche. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.The object of the invention is to provide a reliable electrical connector, which is suitable for use in a bottom bracket arranged on the engine of an electric bicycle. Based on the cited prior art, the object is achieved by the features of the independent claims. Advantageous developments are the subject of the dependent claims.

Bei einem Steckverbinder für einen elektrischen Anschluss eines Elektrofahrrads, umfassend eine Mehrzahl von elektrischen Steckkontakten und eine Steckerwand, die die Steckkontakte in Umfangsrichtung umgibt, ist erfindungsgemäß vorgesehen, dass eine Außenfläche der Steckerwand mit einem umlaufenden Dichtelement versehen ist und dass auf der Außenfläche der Steckerwand ein nach außen vorspringendes Verriegelungselement angeordnet ist.In a connector for an electrical connection of an electric bicycle, comprising a plurality of electrical plug contacts and a connector wall which surrounds the plug contacts in the circumferential direction, the invention provides that an outer surface of the plug wall is provided with a circumferential sealing element and that on the outer surface of the connector wall is arranged outwardly projecting locking element.

Die Erfindung beruht auf dem Gedanken, gleichzeitig beim Einstecken des Steckverbinders sowohl eine Abdichtung in Bezug auf die elektrischen Kontakte als auch eine Verriegelung des Steckverbinders zu erreichen. Dazu weist der Steckverbinder an der Außenfläche der Steckerwand ein umlaufendes Dichtelement auf. Das Dichtelement läuft um die Steckkontakte des Steckverbinders um, so dass die Steckkontakte durch das Dichtelement in einer passenden Buchse abgedichtet werden können.The invention is based on the idea, at the same time when plugging in the connector both a seal in relation to achieve the electrical contacts as well as a locking of the connector. For this purpose, the connector on the outer surface of the connector wall on a circumferential sealing element. The sealing element runs around the plug contacts of the connector, so that the plug contacts can be sealed by the sealing element in a matching socket.

Weiter umfasst die Außenfläche der Steckerwand ein nach außen vorspringendes Verriegelungselement, das den Steckverbinder an der Steckerbuchse verriegelt. Damit ist der Steckverbinder gegen unbeabsichtigtes Lösen gesichert, so dass die elektrische Verbindung solange bestehen bleibt, bis der Steckverbinder von Hand entfernt wird.Further, the outer surface of the connector wall includes an outwardly projecting locking member which locks the connector to the female connector. Thus, the connector is secured against unintentional loosening, so that the electrical connection is maintained until the connector is removed by hand.

Die Außenfläche der Steckerwand ist vorzugsweise parallel zu der Einsteckrichtung des Steckverbinders ausgebildet. Damit kann die Steckerwand unkompliziert in eine passende Buchse eingeführt werden. Das Dichtelement springt mit Vorteil gegenüber der Außenfläche vor, so dass ein verbleibender Zwischenraum zwischen der Außenfläche und der Buchse überbrückt wird. Das Dichtelement kann als Dichtung ausgeführt sein, die in einer Nut der Seitenwand angeordnet ist.The outer surface of the connector wall is preferably formed parallel to the insertion direction of the connector. Thus, the connector wall can be easily inserted into a matching socket. The sealing element projects with advantage over the outer surface, so that a remaining space between the outer surface and the sleeve is bridged. The sealing element may be designed as a seal, which is arranged in a groove of the side wall.

Vorteilhafterweise ist in Einsteckrichtung betrachtet das Dichtelement vor dem Verriegelungselement angeordnet. Indem die Elemente in Einsteckrichtung hintereinander gestaffelt sind, wird ausgenutzt, dass in dieser Richtung regelmäßig ausreichend Platz vorhanden ist. Im Gegenzug wird es möglich, den Steckverbinder in der zur Einsteckrichtung senkrechten Dimension kompakt zu halten.Advantageously, viewed in the insertion direction, the sealing element is arranged in front of the locking element. By staggering the elements one behind the other in the direction of insertion, one makes use of the fact that sufficient space is regularly available in this direction. In turn, it becomes possible to keep the connector compact in the dimension perpendicular to the insertion direction.

Das Verriegelungselement kann sich von der Außenfläche der Steckerwand in Richtung einer Stirnfläche erstrecken. Es ist möglich, die Stirnfläche so zu gestalten, dass sie mit einer Rastvorrichtung der zugehörigen Buchse zusammenwirkt. Allerdings steigt dann der Platzbedarf der elektrischen Steckverbindung in der zur Einsteckrichtung senkrechten Dimension. Von Vorteil ist es deswegen, wenn eine Seitenfläche des Verriegelungselements dazu ausgelegt ist, mit einer Rastvorrichtung zusammenzuwirken. Die Seitenfläche ist seitlich angeordnet bezogen auf die Richtung, die sich von der Außenfläche der Steckerwand zur Stirnfläche erstreckt. Insbesondere kann die Seitenfläche einen geneigten Abschnitt umfassen, der dazu ausgelegt ist, eine Rastvorrichtung beim Einführen des Steckverbinders zu spreizen.The locking element may extend from the outer surface of the connector wall in the direction of an end face. It is possible to arrange the front surface in such a way that it fits with a Detent device of the associated socket cooperates. However, then increases the space requirement of the electrical connector in the direction perpendicular to the insertion dimension. It is advantageous if a side surface of the locking element is designed to cooperate with a locking device. The side surface is disposed laterally with respect to the direction extending from the outer surface of the connector wall to the end surface. In particular, the side surface may comprise an inclined portion which is designed to spread a locking device during insertion of the connector.

Insbesondere kann das Verriegelungselement als Zapfen ausgebildet sein, dessen Achse senkrecht zur Außenfläche der Steckerwand ausgerichtet ist. Die Umfangsfläche des Zapfens bildet die Seitenfläche des Verriegelungselements. Der in Einsteckrichtung weisende Teil der Umfangsfläche ist dazu ausgelegt, eine Rastvorrichtung zu spreizen. Die Länge des Zapfens ist vorzugsweise so bemessen, dass die Stirnfläche nicht gegenüber der Rastvorrichtung vorspringt.In particular, the locking element may be formed as a pin whose axis is aligned perpendicular to the outer surface of the connector wall. The peripheral surface of the pin forms the side surface of the locking element. The pointing in the insertion part of the peripheral surface is designed to spread a locking device. The length of the pin is preferably dimensioned such that the end face does not protrude with respect to the latching device.

Die Steckkontakte eines solchen Steckverbinders sind häufig symmetrisch angeordnet. Unter symmetrisch wird verstanden, dass die Steckkontakte durch eine Rotation um eine entlang der Einsteckrichtung verlaufenden Achse auf einander abgebildet werden können. Um eine Vertauschung der Pole auszuschließen, kann der erfindungsgemäße Steckverbinder mit einem Ausrichtelement versehen sein, so dass die elektrische Verbindung in nur genau einer Ausrichtung des Steckers hergestellt werden kann. Das Ausrichtelement ist vorzugsweise auf einer Innenfläche der Steckerwand angeordnet. Der Steckverbinder kann damit sicher und einfach in der richtigen Ausrichtung in eine passende Buchse einführt werden. Beschädigugnen an elektrischen Geräten, bei denen die Polung der Steckkontakte wichtig ist, werden damit vermieden.The plug contacts of such a connector are often arranged symmetrically. Symmetrically, it is understood that the plug contacts can be imaged on one another by a rotation about an axis running along the plug-in direction. In order to preclude a permutation of the poles, the connector according to the invention may be provided with an alignment element, so that the electrical connection can be made in only one orientation of the connector. The alignment element is preferably arranged on an inner surface of the connector wall. The connector can thus be safely and easily inserted in the correct orientation in a matching socket. Damage electrical devices in which the polarity of the plug contacts is important, are thus avoided.

Mit Vorteil ist ein Innenraum des Steckverbinders mit einem Hotmelt-Material ausgespritzt, wobei sich ein Kabelstrang durch das Hotmelt-Material hindurch erstreckt. Unter einem Hotmelt-Material wird ein Kunststoffmaterial verstanden, das in einem flüssigen, erhitzten Zustand Oberflächen benetzt und sich nach dem Abkühlen dauerhaft verfestigt. Geeignet als solches Hotmelt-Material ist beispielsweise thermoplastisches Polyurethane (TPU). Das Hotmelt-Material dichtet den Raum zwischen dem Kabelstrang und der Innenwand des Steckverbinders ab. Weiter stabilisiert es den Kabelstrang in dem Steckverbinder. Der Kabelstrang kann sich nach Verlassen des Hotmelt-Materials bis zu dem Peripheriegerät erstrecken.Advantageously, an interior of the connector is sprayed with a hotmelt material, wherein a wire harness extends through the hotmelt material. A hotmelt material is understood as meaning a plastic material which, in a liquid, heated state, wets surfaces and solidifies permanently after cooling. Suitable as such hotmelt material is for example thermoplastic polyurethane (TPU). The hotmelt material seals the space between the harness and the inner wall of the connector. It also stabilizes the cable harness in the connector. The harness may extend to the peripheral after exiting the hotmelt material.

Die Erfindung betrifft weiter ein Anschluss-System für ein Elektrofahrrad, umfassend einen erfindungsgemäßen Steckverbinder und ein Anschluss-Bauteil des Elektrofahrrads. Das Anschluss-Bauteil hat eine zu dem Steckverbinder passende Steckerbuchse. Die Steckerbuchse weist eine die elektrischen Kontakte in Umfangsrichtung umgebende Buchsenwand auf. Eine Innenfläche der Buchsenwand ist dazu ausgelegt, einen dichtenden Abschluss mit dem Dichtelement des Steckverbinders zu bilden.The invention further relates to a connection system for an electric bicycle, comprising a connector according to the invention and a connection component of the electric bicycle. The connection component has a plug socket which is suitable for the connector. The socket has a socket surrounding the electrical contacts in the circumferential direction. An inner surface of the bushing wall is adapted to form a sealing termination with the sealing element of the connector.

Mit dem Anschluss-Bauteil des Anschluss-Systems wird eine passende Steckerbuchse für den Steckverbinder bereitgestellt. Beim Einstecken des Steckverbinders wird die Außenfläche der Steckerwand in die Steckerbuchse eingeführt, so dass ein umlaufender Teil der Innenfläche der Buchsenwand um einen umlaufenden Teil der Außenfläche der Steckerwand angeordnet wird. Die Innenfläche der Buchsenwand der Steckerbuchse wird bei Einführung des Steckverbinders in Kontakt mit dem Dichtelement gebracht. Das Dichtelement wird beim Einsteckvorgang zwischen der Außenfläche der Steckerwand und der Innenfläche der Buchsenwand angeordnet. Vorzugsweise ist eine Presspassung derart vorgesehen, dass das Dichtelement senkrecht zur Einsteckrichtung komprimiert wird. Dadurch schließt das Dichtelement den Raum, in dem sich die elektrischen Kontakte und Steckkontakte befinden, von der äußeren Umgebung wasserdicht ab. Wasser, das an den Steckverbinder gelangt, kann damit nicht zwischen der Innenfläche der Buchsenwand und der Außenfläche der Steckerwand zu den elektrischen Kontakten fließen.The connection component of the connection system provides a suitable connector for the connector. When inserting the connector, the outer surface of the connector wall is inserted into the socket, so that a circumferential part of the inner surface of the socket wall is arranged around a peripheral part of the outer surface of the connector wall. The inner surface of the socket wall of the socket is brought in contact with the sealing element at the introduction of the connector. The sealing element is arranged during the insertion process between the outer surface of the connector wall and the inner surface of the bushing wall. Preferably, a press fit is provided such that the sealing element is compressed perpendicular to the insertion direction. As a result, the sealing element closes off the space in which the electrical contacts and plug contacts are located from the outside environment waterproof. Water that gets to the connector, thus can not flow between the inner surface of the female wall and the outer surface of the connector wall to the electrical contacts.

Zweckmäßigerweise weist die Buchsenwand eine Rastvorrichtung auf, in die das Verriegelungselement des Steckverbinders einrastet, wenn der Steckverbinder in Eingriff mit der Buchse steht. Dies ermöglicht die sichere Verriegelung des Steckverbinders an der Steckerbuchse. Die Rastvorrichtung ist vorzugsweise so gestaltet, dass der an die Stirnfläche des Verriegelungselement angrenzende Raum frei bleibt. Dadurch wird es möglich, eine Mehrzahl von Steckerbuchsen auf kleinem Raum nebeneinander anzuordnen.Conveniently, the socket wall has a latching device into which the locking element of the connector engages when the connector is in engagement with the socket. This allows the secure locking of the connector to the socket. The latching device is preferably designed so that the space adjacent to the end face of the locking element remains free. This makes it possible to arrange a plurality of sockets in a small space next to each other.

Die Buchse weist mit Vorteil einen die elektrischen Kontakte umgebenden Sockel auf, wobei eine Außenfläche des Sockels der Innenfläche der Buchsenwand gegenüberliegt. Die Steckerwand wird teilweise oder vollständig in den Zwischenraum zwischen Sockel und Buchsenwand eingeführt. Damit wird der Weg zu den elektrischen Kontakten und den Steckkontakten für an dem Steckverbinder entlang fließendes Wasser verlängert und der Schutz vor eindringender Feuchtigkeit wird weiter erhöht.The socket advantageously has a socket surrounding the electrical contacts, an outer surface of the socket lying opposite the inner surface of the socket wall. The connector wall is partially or completely inserted into the space between the socket and socket wall. This prolongs the path to the electrical contacts and plug contacts for water flowing along the connector and further enhances protection against moisture penetration.

Weiter ist vorteilhafterweise in der Außenfläche des Sockels eine zu dem Ausrichtelement des Steckverbinders passende Gegenstruktur ausgebildet. Damit kann der Steckverbinder nur in einer festgelegten Ausrichtung in die Steckerbuchse eingeführt werden. Die Steckkontakte des Steckverbinders werden nur mit den vorgesehenen elektrischen Kontakten der Steckerbuchse verbunden.Furthermore, a counter-structure matching the alignment element of the connector is advantageously formed in the outer surface of the base. This allows the connector only in a fixed orientation are inserted into the socket. The plug contacts of the connector are connected only to the intended electrical contacts of the socket.

Es ist weiter zweckmäßig, dass das Anschluss-Bauteil ein Gehäuse aufweist, wobei ein Innenraum des Gehäuses mit einem Hotmelt-Material ausgespritzt ist und wobei ein Kabelstrang sich durch das Hotmelt-Material hindurch erstreckt. Mit dem Eingießen des Kabelstrangs in das Hotmelt-Material wird der Übergang zwischen dem Kabelstrang und dem Gehäuse abgedichtet. Weiter werden der Innenraum des Gehäuses sowie die Verbindungen der Kabelstränge zu den elektrischen Kontakten stabiliesiert.It is further expedient that the connection component has a housing, wherein an interior of the housing is sprayed with a hotmelt material and wherein a cable strand extends through the hotmelt material. As the harness is poured into the hotmelt material, the junction between the harness and the housing is sealed. Furthermore, the interior of the housing and the connections of the cable strands to the electrical contacts are stabilized.

Mit Vorteil weist das Anschluss-Bauteil einen von dem Hotmelt-Material gebildeten Dichtabschnitt auf, der dazu ausgelegt ist, eine wasserdichte Verbindung zu dem Motorgehäuse des Elektrofahrrads herzustellen. Der Kabelstrang kann sich durch den Dichtabschnitt hindurch erstrecken. Es wird dazu vorzugsweise ein Hotmelt-Material verwendet, das eine hohe Flexibilität und gute Anschmiegbarkeit aufweist. In Betracht kommt beispielsweise ein Verguss-Polyamid Material. Das Anschluss-Bauteil kann mithilfe des Dichtabschnitts als abdichtende elektrische Durchführung an einem Gehäuse für einen Elektromotor fungieren. Der Dichtabschnitt kann eine Öffnung eines Raums abdichten, in dem elektrische Vorrichtungen wie z.B. Platinen angeordnet sind.Advantageously, the connection component has a sealing section formed by the hot-melt material, which is designed to produce a watertight connection to the motor housing of the electric bicycle. The cable harness may extend through the sealing portion. It is preferably used a hotmelt material that has a high flexibility and good conformability. Considered, for example, a potting polyamide material. The terminal member may function by means of the sealing portion as a sealing electrical feedthrough to a housing for an electric motor. The sealing portion may seal an opening of a space in which electrical devices such as e.g. Circuit boards are arranged.

Der Dichtabschnitt weist vorteilhafterweise zwei als Dichtflächen bestimmte Nuten auf. Die Nuten sind zweckmäßigerweise in einer Ebene angeordnet, durch die eine Einführrichtung definiert wird. Einführrichtung bezeichnet die Richtung, in der das Anschluss-Bauteil in eine zugehörige Ausnehmung des Motorgehäuses eingesetzt wird. Die Einführrichtung ist vorzugsweise parallel zu der Einsteckrichtung des elektrischen Steckverbinders. Die Nuten haben vorzugsweise eine parallel zu der Einführrichtung konisch zulaufende Form. Mittels der konisch zulaufenden Form wirkt der Rand der Ausnehnung wie ein Keil, der in die Nuten gedrückt wird. Dadurch wird eine sichere Abdichtung des Gehäuseinneren bewirkt.The sealing portion advantageously has two grooves designated as sealing surfaces. The grooves are expediently arranged in a plane through which an insertion direction is defined. Insertion direction refers to the direction in which the connection component is inserted into an associated recess of the motor housing. The insertion direction is preferably parallel to the insertion direction of the electrical connector. The grooves preferably have a tapered parallel to the insertion direction form. By means of the tapered shape, the edge of the recess acts like a wedge pressed into the grooves. As a result, a secure seal of the housing interior is effected.

Weiter betrifft die Erfindung ein Elektrofahrrad mit einem solchen Anschluss-System, wobei erfindungsgemäß vorgesehen ist, dass das Elektrofahrrad einen auf die Tretkurbelwelle wirkenden Elektromotor aufweist, wobei der Elektromotor mit einem Elektromotorgehäuse umgeben ist und wobei der Dichtabschnitt des Anschluss-Bauteils mit dem Elektromotorgehäuse abdichtet.Furthermore, the invention relates to an electric bicycle with such a connection system, which is provided according to the invention that the electric bicycle has an acting on the pedal crankshaft electric motor, wherein the electric motor is surrounded by an electric motor housing and wherein the sealing portion of the connection component seals with the electric motor housing.

Die Erfindung betrifft ferner einen Satz von erfindungsgemäßen Steckverbindern, wobei weiter erfindungsgemäß vorgesehen ist, dass wenigstens zwei der Steckverbinder eine übereinstimmende Anordnung von elektrischen Steckkontakten aufweisen und dass die Steckverbinder mit identischer Anordnung der Kontakte voneinander abweichende Ausrichtelemente aufweisen, die ein Vertauschen der Steckverbinder ausschließen. Der Satz kann drei Steckerverbinder mit jeweils zwei elektrischen Kontakten und zwei Steckverbinder mit jeweils fünf elektrischen Kontakten umfassen.The invention further relates to a set of connectors according to the invention, wherein further provided according to the invention that at least two of the connectors have a matching arrangement of electrical plug contacts and that the connectors with identical arrangement of the contacts have different alignment elements, which preclude swapping the connector. The kit can include three male connectors, each with two electrical contacts and two connectors, each with five electrical contacts.

Damit kann jeder Steckverbinder nur in Steckerbuchsen eingeführt werden, die eine passende Gegenstruktur an der Außenfläche des Sockels aufweisen. Dies vereinfacht und beschleunigt die Montage der Steckverbinder, da eine Zuordnung der Steckverbinder zu einem Peripheriegerät nicht zu erfolgen braucht.Thus, each connector can be inserted only in sockets, which have a matching counter-structure on the outer surface of the base. This simplifies and speeds up the assembly of the connectors, since an assignment of the connector to a peripheral device does not need to take place.

Ein Steckverbinder wird in seiner Gesamtheit mit den Bezugszeichen 1 gekennzeichnet. Ein erstes alternatives Ausführungsbeispiel eines Steckverbinders 1 wird in Figur 1 dargestellt.A connector is identified in its entirety by the reference numeral 1. A first alternative embodiment of a connector 1 is shown in FIG FIG. 1 shown.

Der Steckverbinder 1 umfasst sieben Steckkontakte 10, 10', wobei zwei der Steckkontakte 10' als Steckkontakte für eine elektrische Energiequelle bzw. einen elektrischen Energiespeicher dienen. Die weiteren Steckkontakte 10 sind als Kontakte für Signalleitmittel ausgebildet. Die Steckkontakte 10 und 10' sind unterschiedlich ausgeformt. Die elektrischen Kontakte 10, 10' sind von einer Steckerwand 11 umgeben, die um die Steckkontakte 10, 10' umläuft. Die Steckerwand 11 weist eine Außenfläche 12 und eine Innenfläche 13 auf. An der Außenfläche 12 ist ein Dichtelement 14 angeordnet, das aus einer an der Außenfläche 12 umlaufenden Nut mit einer darin angeordneten Dichtung ausgebildet ist. Die Dichtung springt aus der Außenfläche 12 der Steckerwand 11 hervor.The connector 1 comprises seven plug contacts 10, 10 ', wherein two of the plug contacts 10' serve as plug contacts for an electrical energy source or an electrical energy storage. The further plug-in contacts 10 are formed as contacts for Signalleitmittel. The plug contacts 10 and 10 'are formed differently. The electrical contacts 10, 10 'are surrounded by a connector wall 11 which rotates about the plug contacts 10, 10'. The connector wall 11 has an outer surface 12 and an inner surface 13. On the outer surface 12, a sealing element 14 is arranged, which is formed from a circumferential groove 12 on the outer surface with a seal disposed therein. The seal protrudes from the outer surface 12 of the connector wall 11.

Weiter weist die Außenfläche 12 ein Verriegelungselement 15 auf, das als Zapfen ausgebildet ist. Die Außenfläche 12 ist parallel zur Einsteckrichtung ausgebildet, wobei das Dichtelement 14 in Einsteckrichtung vor dem Verriegelungselement 15 angeordnet ist. Damit wird das Dichtelement 14 vor dem Verriegelungselement 15 in eine passende Buchse eingeführt, so dass eine Abdichtung vor der Verriegelung erfolgt.Further, the outer surface 12 on a locking element 15 which is formed as a pin. The outer surface 12 is formed parallel to the insertion direction, wherein the sealing element 14 is arranged in the insertion direction in front of the locking element 15. Thus, the sealing element 14 is inserted in front of the locking element 15 in a matching socket, so that a seal is made before the lock.

In Figur 2 wird ein Anschluss-Bauteil dargestellt, das in seiner Gesamtheit mit dem Bezugszeichen 2 bezeichnet wird. Das Anschluss-Bauteil 2 weist eine zum Steckverbinder 1 passende Steckerbuchse 20 auf. In einem Sockel 23 der Steckerbuchse 20 sind elektrische Kontakte 18, 18' angeordnet. Die elektrische Kontakte 18' sind als Gegenstücke zu den Steckkontakten 10' ausgebildet. Weiter sind die elektrischen Kontakte 18 als Gegenstücke zu den Steckkontakten 10 augebildet. Alle elektrischen Kontakte 18, 18' sind passend zu den Steckkontakten 10, 10' angeordnet. Die elektrischen Kontakte 18, 18' im Sockel 23 sind von einer Buchsenwand 21 umgeben. Die Buchsenwand 21 umfasst eine Innenfläche 22. Die Innenfläche 22 der Buchsenwand 21 ist der einer Außenfläche 24 des Sockels 23 gegenüber angeordnet.In FIG. 2 a connection component is shown, which is designated in its entirety by the reference numeral 2. The connection component 2 has a plug socket 20 which is suitable for the connector 1. In a socket 23 of the socket 20 electrical contacts 18, 18 'are arranged. The electrical contacts 18 'are formed as counterparts to the plug contacts 10'. Further, the electrical contacts 18 are formed as counterparts to the plug contacts 10. All electrical contacts 18, 18 'are arranged to match the plug contacts 10, 10'. The electrical contacts 18, 18 'in the base 23 are surrounded by a bushing wall 21. The bushing wall 21 includes an inner surface 22. The inner surface 22 of the female wall 21 is disposed opposite to an outer surface 24 of the base 23.

Die Steckkontakte 10, 10' dieser ersten alternativen Ausführungsform sind nicht symmetrisch angeordnet, so dass die Steckverbindung 1 in nur einer einzigen Ausrichtung in die Steckerbuchse 20 eingeführt werden kann.The plug contacts 10, 10 'of this first alternative embodiment are not arranged symmetrically, so that the connector 1 can be inserted into the socket 20 in only a single orientation.

Wenn der Steckverbinder 1 in die Steckerbuchse 20 eingeführt ist, ist die Steckerwand 11 in dem Zwischenraum zwischen dem Sockel 23 und der Buchsenwand 21 angeordnet. Dabei bildet die Innenfläche 22 der Buchsenwand 21 einen dichtenden Abschluss mit dem aus der Außenfläche 12 der Steckerwand 11 hervorspringenden Dichtelement 14 des Steckverbinders 1.When the connector 1 is inserted into the female connector 20, the connector wall 11 is disposed in the space between the socket 23 and the female wall 21. In this case, the inner surface 22 of the socket wall 21 forms a sealing closure with the protruding from the outer surface 12 of the connector wall 11 sealing element 14 of the connector first

Die Buchsenwand 21 weist weiter eine Rastvorrichtung 25 auf, die zu dem Verriegelungselement 15 des Steckverbinders 1 passt. Das Verriegelungselement 15 rastet in die Rastvorrichtung 25 ein, wenn der Steckverbinder 1 in die Steckerbuchse 20 eingeführt ist. Um den Steckverbinder 1 von der Steckerbuchse 20 zu lösen, muss die Rastverbindung zwischen dem Verriegelungselement 15 und der Rastvorrichtung 25 überdrückt werden. Damit wird eine unabsichtliche Lösung der Rastverbindung durch Erschütterungen verhindert. Figur 4b stellt ein Anschluss-System dar, bei dem die Steckverbindungen 1 in das Anschluss-Bauteil 2 eingeführt sind, wobei die Verriegelungselemente 15 mit den Rastvorrichtungen 25 zusammenwirken. Weiter ist in der Figur 4b eine Wand des Gehäuses 27 des Anschluss-Bauteils 2 transparent dargestellt, so dass die Dichtelemente 14 der Steckverbindungen 1 sichtbar sind. Die Dichtelemente 14 sind an die Innenfläche 22 der Buchsenwand 21 gedrückt, so dass sie eine Abdichtung des Raums bilden, in den die elektrischen Kontakte 18, 18' sowie die Steckkontakte 10, 10' angeordnet sind.The socket wall 21 further has a latching device 25 which fits to the locking element 15 of the connector 1. The locking element 15 engages in the latching device 25 when the connector 1 is inserted into the socket 20. In order to release the connector 1 from the socket 20, the locking connection between the locking element 15 and the latching device 25 must be suppressed. This prevents an unintentional solution of the latching connection due to vibrations. FIG. 4b represents a connection system in which the connectors 1 are inserted into the connection component 2, wherein the locking elements 15 cooperate with the locking devices 25. Next is in the FIG. 4b a wall of the housing 27 of the connection component 2 is shown transparent, so that the sealing elements 14 of the connectors 1 are visible. The sealing elements 14 are pressed against the inner surface 22 of the socket wall 21, so that they form a seal of the space in which the electrical contacts 18, 18 'and the plug contacts 10, 10' are arranged.

Im Innenraum 17 des Steckverbinders 1 sind die Steckkontakte 10, 10' mit Kabeln verbunden, wie in Figur 3 dargestellt wird. Die Kabel werden als Kabelstrang 4 aus dem Steckverbinder 1 herausgeführt. Der Innenraum 17 ist zur Abdichtung mit einem Hotmelt-Material ausgespritzt. Der Kabelstrang 4 erstreckt sich dabei durch das Hotmelt-Material hindurch. Er ist in das Hotmelt-Material eingegossen. Das Hotmelt-Material dichtet den Innenraum 17 des Steckverbinders 1 nach außen hin ab. Damit kann kein Spritz- oder Regenwasser an die stromführenden Leitungen gelangen. Das Hotmelt-Material, mit dem der Innenraum 17 des Steckverbinders 1 ausgespritzt ist, kann ein thermoplastisches Urethan sein.In the interior 17 of the connector 1, the plug contacts 10, 10 'are connected to cables, as in FIG. 3 is pictured. The cables are led out as a cable harness 4 from the connector 1. The interior 17 is sprayed with a hotmelt material for sealing. The cable strand 4 extends through the hotmelt material. He is poured into the hotmelt material. The hotmelt material seals the interior 17 of the connector 1 to the outside. Thus, no splash or rain water can get to the power lines. The hotmelt material, with which the interior 17 of the connector 1 is injected, may be a thermoplastic urethane.

Das Anschluss-Bauteil 2 weist weiter ein Gehäuse 27 mit einem Innenraum 6 auf, in dem die elektrischen Kontakte 18 mit einem Kabelstrang 5 verbunden sind. Der Kabelstrang 5 wird aus dem Innenraum 6 hinausgeführt, um mit der Platine eines Elektromotors 31 verbunden zu werden. Der Innenraum 6 des Anschluss-Bauteils 2 ist mit einem Hotmelt-Material ausgespritzt. Der Kabelstrang 5 ist dadurch von dem Hotmelt-Material umgeben. Das Hotmelt-Material dichtet den Innenraum 6 des Gehäuses 27 nach außen ab, so dass entlang der Kabel 5 keine Feuchtigkeit in das Anschluss-Bauteil 2 gelangen kann. Das Hotmelt-Material, mit dem das Gehäuse 27 ausgespritzt wird, kann ein Verguss-Polyamid sein.The connection component 2 further has a housing 27 with an interior 6, in which the electrical contacts 18 are connected to a cable harness 5. The wire harness 5 is led out of the inner space 6 to be connected to the board of an electric motor 31. The interior 6 of the connection component 2 is sprayed with a hotmelt material. The cable strand 5 is thereby surrounded by the hotmelt material. The hotmelt material seals the interior 6 of the housing 27 to the outside, so that no moisture can get into the connection component 2 along the cable 5. The hotmelt material with which the housing 27 is injected may be a potting polyamide.

Figuren 5a-c und 5d-e zeigen je einen Satz einer alternativen Ausführungsform des Steckverbinders 1. Die beiden Sätze der Steckverbinder 1 weisen jeweils eine übereinstimmende Anordnung von symmetrisch angeordneten Steckkontakten 10 auf. Sie unterscheiden sich in den Ausrichtelementen 16, die an der Innenfläche 13 der Steckerwand 11 angeordnet sind. Mittels der Ausrichtelementen 16 ist die Ausrichtung jeder Steckverbindung 1 festgelegt. Sie kann trotz der symmetrischen Anordnung der Steckkontakte 10 nicht vertauscht werden. Figures 5a-c and 5d-e each show a set of an alternative embodiment of the connector 1. The two sets of connectors 1 each have a matching arrangement of symmetrically arranged plug contacts 10. They differ in the alignment elements 16, which are arranged on the inner surface 13 of the connector wall 11. through the alignment elements 16, the orientation of each connector 1 is fixed. You can not be reversed despite the symmetrical arrangement of the plug contacts 10.

Weiter weisen die Steckerbuchsen 20 einer in Figur 4a dargestellten zweiten alternativen Ausführungsform des Anschluss-Bauteils 2 zu den Ausrichtelementen 16 passende Gegenstrukturen 26 auf, die an den Sockel 23 angeordnet sind. Die Steckverbinder 1 eines Steckverbinder-Satzes können damit nicht untereinander vertauscht werden. Damit ist jeder Steckverbinder 1 einer Steckerbuchse 20 fest zugeordnet.Next, the sockets 20 have an in FIG. 4a illustrated second alternative embodiment of the terminal component 2 to the alignment elements 16 matching counter-structures 26, which are arranged on the base 23. The connectors 1 of a connector set can not be interchanged with each other. Thus, each connector 1 is assigned to a female connector 20 fixed.

In Figur 7 ist dargestellt, wie ein Anschluss-Bauteil 2 an ein Gehäuse 32 eines Elektromotors 31 angeordnet sein kann. Das Anschluss-Bauteil 2 weist zum Anschluss an das Gehäuse 32 einen Dichtabschnitt 29 auf. Der Dichtabschnitt 29 umfasst zwei Nuten 28, die in Einführrichtung konisch ausgebildet sind. Mittels des Dichtabschnitts 29 kann das Anschluss-Bauteil 2 in eine passend ausgestaltete Ausnehmung am Gehäuse 32 des Elektromotors 31 angeordnet werden. Um einfach in die Ausnehmung am Gehäuse 32 eingeführt zu werden, sind die Nuten 28 in einer Ebene angeordnet. Das Anschluss-Bauteil 2 bildet dann die Durchführung der elektrischen Leitung von dem Inneren des Gehäuses 32 nach außen. Die Nuten 28 dichten dabei Ausnehmung am Gehäuse 32 ab. Durch die konisch zulaufende Form der Nuten 28 kann der Rand der Ausnehmung wie ein Keil in die Nuten 28 hineingedrückt werden und bildet damit eine abdichtende Verbindung.In FIG. 7 It is illustrated how a connection component 2 can be arranged on a housing 32 of an electric motor 31. The connection component 2 has a sealing section 29 for connection to the housing 32. The sealing portion 29 comprises two grooves 28 which are conical in the insertion direction. By means of the sealing portion 29, the connection component 2 can be arranged in a suitably configured recess on the housing 32 of the electric motor 31. To be easily inserted into the recess on the housing 32, the grooves 28 are arranged in a plane. The terminal component 2 then forms the passage of the electrical line from the interior of the housing 32 to the outside. The grooves 28 thereby seal recess on the housing 32. Due to the tapered shape of the grooves 28, the edge of the recess can be pressed like a wedge into the grooves 28 and thus forms a sealing connection.

Der Kabelstrang 5, der aus dem Anschluss-Bauteil 2 herausgeführt wird, weist an seinem Ende Stecker 33 auf, die mit der Platine eines Elektromotors 31 verbunden werden können. Der Elektromotor ist wie in Figur 6 dargestellt im Tretlager eines Elektrofahrrads 3 angeordnet. Er unterstützt die Tretkurbelwelle 30 während der Fahrt, wenn zusätzliche Energie zur Beschleunigung oder bei Steigungen benötigt wird. Wenn keine Energie benötigt wird, nimmt er zusätzliche Energie auf, die zum Beispiel durch Bremsmanöver frei werden kannn. Über das Anschluss-Bauteil 2 und die Steckverbinder 1 mit den Kabelsträngen 4 ist der Elektromotor 31 mit Peripheriegeräten 34 verbunden. Sie werden durch den Elektromotor 31 mit Energie versorgt und können zum Beispiel Daten über die Geschwindigkeit an den Elektromotor 31 übermitteln.The harness 5, which is led out of the connection component 2, has at its end plug 33, which can be connected to the circuit board of an electric motor 31. The electric motor is like in FIG. 6 represented in the bottom bracket of a Electric bicycle 3 arranged. It supports the crankshaft 30 during travel when additional energy is needed for acceleration or uphill gradients. When no energy is needed, it absorbs additional energy, which can be released by braking maneuvers, for example. About the terminal component 2 and the connector 1 with the cable strands 4 of the electric motor 31 is connected to peripherals 34. They are powered by the electric motor 31 and can, for example, transmit speed data to the electric motor 31.
