Description

Steckverbindung für einen Akku-Ladeanschluss ohne formschlüssige Gehäuseverrastung  Plug-in connection for a rechargeable battery charging connection without form-locking housing latching
Beschreibung description
Die Erfindung betrifft eine Steckverbindung, aufweisend eine Einbaubuchse und einen damit zusammensteckbaren Steckverbinder, gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1 . The invention relates to a plug-in connection, comprising a mounting socket and a connector plugged together, according to the features of the preamble of claim 1.
Für einen Akku-Ladeanschluss, insbesondere an einem Elektrofahrzeug, wird eine Steckverbindung benötigt, welche keine formschlüssige Gehäuseverrastung aufweisen darf. Hintergrund dieser Anforderung ist ein vorsorgliches Vermeiden von Beschädigungen am Ladestecker, wenn der Endkunde den Stecker ohne Betätigen der Verriegelung abzieht. Trotzdem soll dem Kunden ein haptisches Feedback für den ordentlichen Steckvorgang gegeben werden. Folglich wird eine Art kraftschlüssige Verrastung benötigt. Die Herausforderung liegt dabei in der hohen Steckhäufigkeit von mindestens 1 .000 Steckzyklen und der damit verbundenen Problematik der gleichbleibend spürbaren Verrastung. Wenn zum Beispiel kleine Noppen oder eine umlaufende Rippe am Stecker angebracht werden, welche in einem Hinterschnitt in der Einbaubuchse verrasten, ist davon auszugehen, dass sich dieser Kraftschluss anfangs noch sehr streng oder hart, jedoch über die Lebensdauer kaum mehr spürbar beziehungsweise weich anfühlt. For a rechargeable battery charging connection, in particular to an electric vehicle, a plug connection is required, which may not have a form-fitting housing latching. The background of this requirement is a precautionary avoidance of damage to the charging plug if the end user withdraws the plug without actuating the lock. Nevertheless, the customer should be given a haptic feedback for the proper mating process. Consequently, a kind of frictional locking is needed. The challenge lies in the high insertion frequency of at least 1, 000 mating cycles and the associated problem of consistently noticeable locking. If, for example, small knobs or a circumferential rib are attached to the plug, which engage in an undercut in the mounting socket, it is assumed that this frictional connection initially very strong or hard, but hardly felt or soft over the life.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Steckverbindung bereitzustellen, die gemäß den vorstehend geschilderten Anforderungen eingesetzt werden kann. The invention is therefore based on the object to provide a connector that can be used according to the requirements outlined above.
Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. This object is solved by the features of claim 1.
Erfindungsgemäß ist vorgesehen, dass eine an dem Steckverbinder befindliche Radialdichtung so ausgeformt beziehungsweise angeordnet ist, dass diese in einen umlaufenden Hinterschnitt in der Einbaubuchse eintaucht. Dadurch wird in vorteilhafter Weise die Radialdichtung zum einen dazu genutzt, den Steckverbinder gegenüber der Einbaubuchse abzudichten, wenn diese beiden Elemente zu der Steckverbindung zusammengesteckt worden sind. Gleichzeitig wird das erforderliche haptische Feedback bei dem Vorgang des Zusammensteckens (Steckzyklus) dadurch realisiert, dass die Oberfläche der Radialdichtung, d. h., derjenige Bereich der Radialdichtung, die umlaufend von dem Steckverbinder absteht, in den entsprechenden umlaufenden Hinterschnitt in der Einbaubuchse eintaucht. Für die konstruktive Realisierung ist somit bei dem Steckverbinder, der ein Gehäuse aufweist, innerhalb dessen Kontaktpartner angeordnet sind, eine nach außen abstehende Radialdichtung vorhanden, wobei auch bei der Einbaubuchse, die ebenfalls ein Gehäuse mit einem Aufnahmeraum für zumindest einen Teil des Steckverbinders aufweist, in diesem Aufnahmeraum der umlaufende Hinterschnitt vorgesehen ist. Der abstehende Bereich der Radialdichtung korrespondiert entsprechend mit dem umlaufenden Hinterschnitt, zum Beispiel einer umlaufenden Nut, in dem Gehäuse der Einbaubuchse. Die beiden Gehäuse jeweils des Steckverbinders und der Einbaubuchse sind entsprechend aufeinander abgestimmt, sodass der Steckverbinder in die Einbaubuchse eingesteckt werden kann, wobei bei diesem Einsteckvorgang die Kontaktpartner dieser beiden Elemente miteinander in Verbindung gebracht werden und gleichzeitig mittels der Radialdichtung nicht nur eine Abdichtung gegenüber Längswassereintreten realisiert wird, sondern auch das haptische Feedback für den Anwender gegeben wird. In Weiterbildung der Erfindung ist vorgesehen, dass die Radialdichtung als ein in eine umlaufende Ausnehmung des Steckverbinders eingesetzter O-Ring ausgebildet ist. Das Gehäuse des Steckverbinders weist hierzu eine entsprechende umlaufende Vertiefung, zum Beispiel eine umlaufende Nut, auf, in die der O-Ring als separates Bauteil nach der Herstellung des Steckverbinders eingesetzt werden kann. Dabei ist sicherzustellen, dass das Material und die Form (insbesondere der Querschnitt) dieses O-Ringes so gewählt wird, dass einerseits eine zuverlässige Abdichtung des Steckverbinders gegenüber der Einbaubuchse im zusammengesteckten Zustand gewährleistet ist und andererseits das haptische Feedback nach einer Vielzahl von Steckvorgängen, oftmals mehrere 100, wenn nicht sogar mehrere 1000 Steckvorgänge (Steckzyklen), erhalten bleibt. Die Radialdichtung muss keinen runden Querschnitt, sondern kann auch davon abweichende Querschnitte (wie zum Beispiel in den Figuren dargestellt) aufweisen. According to the invention, it is provided that a radial seal located on the connector is formed or arranged such that it dips into a circumferential undercut in the mounting socket. As a result, the radial seal is advantageously used on the one hand to seal off the plug connector relative to the panel socket, when these two elements have been plugged together to form the plug connection. At the same time the required haptic feedback in the process of mating (plug-in cycle) is realized in that the surface of the radial seal, ie, that portion of the radial seal which projects circumferentially from the connector, dips into the corresponding circumferential undercut in the mounting socket. Thus, in the case of the plug connector, which has a housing within which contact partners are arranged, an outwardly projecting radial seal is present for the constructive realization, whereby also in the panel socket, which likewise has a housing with a receiving space for at least a part of the plug connector this receiving space of the circumferential undercut is provided. The protruding region of the radial seal corresponds correspondingly with the circumferential undercut, for example, a circumferential groove in the housing of the mounting socket. The two housings each of the connector and the socket are matched accordingly, so that the connector can be inserted into the mounting socket, in this insertion the contact partners of these two elements are brought together and at the same time realized by means of the radial seal not only a seal against Längswassereintreten but also the haptic feedback is given to the user. In a further development of the invention, it is provided that the radial seal is formed as an inserted into a circumferential recess of the connector O-ring. The housing of the connector has for this purpose a corresponding circumferential recess, for example, a circumferential groove, in which the O-ring can be used as a separate component after the production of the connector. It should be ensured that the material and the shape (in particular the cross-section) of this O-ring is chosen so that on the one hand reliable sealing of the connector against the panel jack is ensured in the assembled state and on the other hand, the haptic feedback after a variety of mating operations, often Several 100, if not several, 1000 plug-in operations (mating cycles) are retained. The radial seal does not have a round cross section, but may also have different cross sections (as shown for example in the figures).
In Weiterbildung der Erfindung ist vorgesehen, dass die Radialdichtung unlösbar mit dem Steckverbinder verbunden ist. Die Realisierung einer solchen unlösbaren Verbindung erfolgt beispielsweise dadurch, dass der Steckverbinder und die Radialdichtung in einem an sich bekannten 2-Komponenten-Kunststoff- Spritzgussverfahren hergestellt werden. Das Gehäuse des Steckverbinders wird dabei aus einem harten Kunststoffmaterial hergestellt, wohingegen die Radialdichtung aus einem demgegenüber weicheren Kunststoffmaterial hergestellt wird. Die Herstellung eines solchen Steckverbinders mit einer unlösbar an ihm, d. h. an seinem Gehäuse angeordneten Radialdichtung hat den Vorteil, dass nicht zwei voneinander separate Teile hergestellt und gehandhabt sowie montiert werden müssen. Dadurch wird der Herstellungsvorgang eines solchen Steckverbinders deutlich vereinfacht. In Weiterbildung der Erfindung ist vorgesehen, dass die Einbaubuchse eine nach innen weisende umlaufende und mit einer Erhebung der Radialdichtung zusammenwirkende Nut aufweist. Eine solche nach innen weisende umlaufende und mit der Erhebung der Radialdichtung zusammenwirkende Nut kann schon mit Herstellung des Gehäuses der Einbaubuchse in dieses eingebracht werden. Alternativ ist es denkbar, eine solche Nut nach der Herstellung des Gehäuses der Einbaubuchse in dieses einzubringen. Der Querschnitt dieser umlaufenden Nut korrespondiert mit der von der Oberfläche des Gehäuses des Steckverbinders abstehenden Erhebung der Radialdichtung, sodass der Querschnitt dieser abstehenden Erhebung genauestens auf den Querschnitt der umlaufenden Nut abgestimmt werden kann, um sowohl die Abdichtung zwischen Einbaubuchse und Steckverbinder als auch das haptische Feedback bei dem Steckvorgang zu optimieren. In a further development of the invention it is provided that the radial seal is permanently connected to the connector. The realization of such a permanent connection takes place, for example, in that the plug connector and the radial seal are produced in a per se known 2-component plastic injection molding process. The housing of the connector is made of a hard plastic material, whereas the radial seal is made of a contrast softer plastic material. The preparation of such a connector with an inextricably attached to it, ie arranged on its housing radial seal has the advantage that not two separate parts must be made and handled and assembled. As a result, the manufacturing process of such a connector is significantly simplified. In a further development of the invention it is provided that the mounting socket has an inwardly directed circumferential and cooperating with a survey of the radial seal groove. Such an inwardly directed circumferential and cooperating with the collection of the radial seal groove can be introduced with the production of the housing of the mounting socket in this. Alternatively, it is conceivable to introduce such a groove after the production of the housing of the mounting socket in this. The cross section of this circumferential groove corresponds to the projecting from the surface of the housing of the connector elevation of the radial seal, so that the cross section of this protruding elevation can be accurately matched to the cross section of the circumferential groove to both the seal between the socket and connector and the haptic feedback to optimize in the mating process.
In Weiterbildung der Erfindung ist vorgesehen, dass die Einbaubuchse und der Steckverbinder ohne eine formschlüssige Gehäuseverrastung zusammensteckbar gestaltet sind. Der Entfall einer formschlüssigen Verbindung zwischen dem Gehäuse der Einbaubuchse und dem Gehäuse des Steckverbinders hat den Vorteil, dass Mittel, die eine solche formschlüssige Gehäuseverrastung bewirken würden, entfallen können. Dadurch vereinfacht sich die Gestaltung der beiden Elemente der Steckverbindung wesentlich. Außerdem vereinfacht sich dadurch der Zusammensteckvorgang, da der Anwender keine Kräfte aufbringen muss, um eine solche formschlüssige Verbindung zwischen dem Gehäuse der Einbaubuchse und dem Gehäuse des Steckverbinders zu bewirken. Das haptische Feedback wird dem Anwender beim Zusammenstecken von Einbaubuchse und Steckverbinder durch die Radialdichtung des Steckverbinders gegeben, die mit ihrer Erhebung in die entsprechende Geometrie, insbesondere die umlaufende Nut, in das Gehäuse der Einbaubuchse eingreift. Somit vereint die Radialdichtung zwei Funktionen, nämlich die Abdichtung gegen Längswasser und das haptische Feedback für den Anwender. In a further development of the invention it is provided that the mounting socket and the connector are designed to be plugged together without a positive locking housing. The elimination of a positive connection between the housing of the mounting socket and the housing of the connector has the advantage that means that would cause such a form-fitting Gehäuseverrastung can be omitted. As a result, the design of the two elements of the connector simplified substantially. In addition, this simplifies the assembly process, since the user does not have to apply forces to effect such a positive connection between the housing of the female connector and the housing of the connector. The haptic feedback is given to the user when plugging the socket and connectors through the radial seal of the connector, with their collection in the corresponding geometry, in particular the circumferential groove in the housing Panel socket engages. Thus, the radial seal combines two functions, namely the seal against longitudinal water and the haptic feedback for the user.
Ein Ausführungsbeispiel eine erfindungsgemäßen Steckverbindung ist in den Figuren 1 bis 3 gezeigt und im Folgenden erläutert. An embodiment of a connector according to the invention is shown in Figures 1 to 3 and explained below.
In den Figuren 1 und 3 ist, soweit im einzelnen erkennbar, eine Steckverbindung 1 dargestellt. Die Steckverbindung 1 umfasst eine Einbaubuchse 2 sowie einen Steckverbinder 3, die zu der Steckverbindung 1 lösbar zusammengesteckt werden können. In den Figuren 1 und 3 ist die Steckverbindung 1 im zusammengesteckten Zustand dargestellt, bei der der Steckverbinder 3 in einen entsprechend gestalteten Aufnahmeraum der Einbaubuchse 2 eintaucht. Selbstverständlich vorhanden, jedoch nicht dargestellt, sind Kontaktpartner, die innerhalb von den Gehäusen, die ebenfalls nicht im Detail dargestellt sind, der Einbaubuchse 2 und des Steckverbinders 3 angeordnet sind. In Figures 1 and 3, as far as can be seen in detail, a connector 1 is shown. The connector 1 comprises a mounting socket 2 and a connector 3, which can be detachably mated to the connector 1. In the figures 1 and 3, the connector 1 is shown in the assembled state, in which the connector 3 dips into a correspondingly shaped receiving space of the mounting socket 2. Of course, but not shown, are contact partners, which are arranged within the housings, which are also not shown in detail, the female connector 2 and the connector 3.
In Figur 1 ist erkennbar, dass der Steckverbinder 3 eine Radialdichtung 4 aufweist. Die Radialdichtung 4 ist einmal umlaufend um das Gehäuse des Steckverbinders 3 angeordnet. Sie bewirkt zum einen, dass kein Längswasser aus Richtung des Steckverbinders 3 in Richtung der Einbaubuchse 2 (oder gegebenenfalls auch umgekehrt) fließen kann. Gleiches gilt für Feuchtigkeit, Verschmutzungen durch Materialpartikel oder dergleichen. Zum anderen bewirkt die Radialdichtung 4, dass beim Einsteckvorgang, d. h. wenn der Steckverbinder 3 in den Aufnahmeraum des Gehäuses der Einbaubuchse 2 hinein bewegt wird, dem Anwender ein haptisches Feedback gegeben wird. Um den Einsteckvorgang zu erleichtern, ist an dem offenen Ende des Aufnahmeraumes des Gehäuses der Einbaubuchse 2 eine Abschrägung (Anfasung) angeordnet, über die die Radialdichtung 4 bei dem Einsteckvorgang gleiten kann. In Figure 1 it can be seen that the connector 3 has a radial seal 4. The radial seal 4 is arranged once circumferentially around the housing of the connector 3. It causes, on the one hand, that no longitudinal water can flow from the direction of the connector 3 in the direction of the panel socket 2 (or possibly also vice versa). The same applies to moisture, contamination by material particles or the like. On the other hand, the radial seal 4 causes the haptic feedback to be given to the user during the insertion process, ie when the connector 3 is moved into the receiving space of the housing of the mounting socket 2. In order to facilitate the insertion, is at the open end of the receiving space of the housing of the mounting socket 2 a bevel (Beveling) arranged over which the radial seal 4 can slide in the insertion process.
In Figur 2 ist eine beispielhafte konstruktive Ausgestaltung der Einbaubuchse 2, des Steckverbinders 3 und der Radialdichtung 4 gezeigt. Zum einen weist der Steckverbinder 3 eine Vertiefung auf, in die die Radialdichtung 4 entweder als separates Bauteil eingesetzt ist oder in die mit Herstellung des Gehäuses des Steckverbinders 3 das Material, das die Radialdichtung 4 bildet, eingespritzt worden ist. Die Radialdichtung 4 weist eine Erhebung 5 auf, mit der die Radialdichtung 4 über die Oberfläche des Gehäuses des Steckverbinders 3 übersteht. Korrespondierend zu dieser Erhebung 5 weist das Gehäuse der Einbaubuchse 2 eine nach innen weisende Vertiefung, insbesondere eine umlaufende Nut 6, auf. Die Geometrie der Erhebung 5 der Radialdichtung 4 sowie der umlaufenden Nut 6 sind derart aufeinander abgestimmt, dass, wie vorstehend schon erwähnt, die Längswasserdichtheit realisiert und das haptische Feedback über eine Vielzahl von Steckvorgängen (Steckzyklen) gegeben wird. 2 shows an exemplary structural design of the mounting socket 2, the connector 3 and the radial seal 4 is shown. On the one hand, the connector 3 has a recess into which the radial seal 4 is either used as a separate component or in the manufacture of the housing of the connector 3, the material which forms the radial seal 4 has been injected. The radial seal 4 has a survey 5, with which the radial seal 4 projects beyond the surface of the housing of the connector 3. Corresponding to this survey 5, the housing of the mounting socket 2 has an inwardly facing recess, in particular a circumferential groove 6, on. The geometry of the survey 5 of the radial seal 4 and the circumferential groove 6 are coordinated so that, as already mentioned, the longitudinal water seal realized and the haptic feedback on a variety of plug-in operations (mating cycles) is given.
In Figur 3 ist beispielhaft eine Anwendung der erfindungsgemäßen Steckverbindung 1 dargestellt. Die Einbaubuchse 2 ist in einer entsprechenden Ausnehmung einer Grundplatte 7 angeordnet und dort befestigt. Die Befestigung erfolgt beispielsweise durch eine Schraubverbindung, hier vier Schraubverbindungen 8, in der Grundplatte 7. Andere Arten der Befestigung, wie zum Beispiel Verrastungen, Verklebungen oder dergleichen, sind selbstverständlich auch denkbar. Die Grundplatte 7 ist beispielsweise Bestandteil einer Karosserie eines Elektrofahrzeuges, in der die Einbaubuchse 2 angeordnet und von außen zugänglich ist, um einen Ladevorgang eines Energiespeichers des Elektrofahrzeuges zu bewerkstelligen, wenn der Steckverbinder 3 in die Einbaubuchse 2 eingesteckt worden ist. Hierzu sind für einen solchen Ladevorgang eines Energiespeichers des Elektrofahrzeuges die Einbaubuchse 2 und der Steckverbinder 3 aufeinander abgestimmt, um insbesondere die erforderlichen Ladeströme zu realisieren. Bei dem im Figur 3 dargestellten Ausführungsbeispiel der Steckverbindung 1 ist der Steckverbinder 3 am Ende eines entsprechend dimensionierten Kabels 9 angeordnet, wobei an dem Eintritt des Kabels 9 in das Gehäuse des Steckverbinders 3 für die Dauerhaltbarkeit ein Knickschutz 10 vorgesehen ist. Das Kabel 9 ist mit einer entsprechenden Ladevorrichtung (nicht dargestellt) verbunden, genauso wie die Einbaubuchse 2 eine elektrische Verbindung zu dem Energiespeicher des Elektrofahrzeuges bzw. einer entsprechenden Ladesteuervorrichtung aufweist. FIG. 3 shows by way of example an application of the connector 1 according to the invention. The mounting socket 2 is arranged in a corresponding recess of a base plate 7 and fixed there. The attachment is done for example by a screw, here four screw 8, in the base plate 7. Other types of attachment, such as locking, bonding or the like, are of course also conceivable. The base plate 7 is for example part of a body of an electric vehicle, in which the mounting socket 2 is arranged and accessible from the outside, to accomplish a charging of an energy storage of the electric vehicle, when the connector 3 has been inserted into the mounting socket 2. This is for a such charging of an energy storage of the electric vehicle, the mounting socket 2 and the connector 3 matched to each other in particular to realize the required charging currents. In the embodiment of the connector 1 shown in Figure 3, the connector 3 is disposed at the end of a correspondingly sized cable 9, wherein at the entrance of the cable 9 in the housing of the connector 3 for durability a kink protection 10 is provided. The cable 9 is connected to a corresponding charging device (not shown), as well as the socket 2 has an electrical connection to the energy storage of the electric vehicle or a corresponding charging control device.
Mit der erfindungsgemäßen Steckverbindung soll somit allgemein eine dichtende Verbindung beim zusammen stecken von Steckverbinder in die Einbaubuchse bei gleichzeitigem haptischen Feedback für den Anwender realisiert werden. With the connector according to the invention thus generally a sealing connection when plugged together of connectors in the mounting socket with simultaneous haptic feedback for the user to be realized.
Um diese Problemstellung zu lösen, sieht die Erfindung mit anderen Worten vor, sich der ohnehin benötigten Gehäusedichtung zu bedienen. Hierfür wird die am Stecker (wahlweise an einer Abdeckkappe) befindliche Radialdichtung so ausgeformt beziehungsweise angeordnet, dass diese in einem umlaufenden Hinterschnitt in der Einbaubuchse eintaucht. Dadurch erfährt der Anwender ein spürbares Feedback zum vollzogenen Steckvorgang. Über die weiche Dichtung ist wiederum sichergestellt, dass die Haptik des Steckvorganges möglichst unverändert über Lebensdauer bleibt, da bei der Dichtung keine Abnützungserscheinungen in Form von Abschabungen oder Ähnlichem zu erwarten sind. Bezugszeichenliste To solve this problem, the invention provides in other words, to use the already needed housing seal. For this purpose, the on the plug (optionally on a cap) located radial seal is formed or arranged so that it dips in a circumferential undercut in the mounting socket. This gives the user a noticeable feedback on the completed plug-in process. About the soft seal is in turn ensured that the haptics of the mating process remains unchanged as possible over life, as the seal no signs of wear in the form of Abschabungen or the like can be expected.
