Abstract

Contact socket for electric plug-in connections comprising a socket-type contact part (2) for receiving a plug pin and a preferably flat connection piece (3), which adjoins the end region of the contact part forming an extension thereof, for connecting electric lines. The aim of the invention is to provide a contact socket, which is simple to produce and has precisely defined contact points that guarantee a secure contacting method. To achieve this, on at least one plane (4a, 4b) perpendicular to the axis of the socket (2), the latter has contact elements (5a-5c, 6a-6c) in at least one position, preferably in three positions, which are detached from the socket jacket on three sides and which protrude inwards. Said elements are arranged in an offset manner on different planes (4a, 4b) perpendicular to the axis of the socket (2) over the circumference of the socket.

Description

RUNDKONTAKTSYSTEM ROUND CONTACT SYSTEM
Die vorliegende Erfindung bezieht sich auf eine Kontakthülse für elektrische Steckvorrichtungen gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a contact sleeve for electrical plug devices according to the preamble of claim 1.
Steckvorrichtungen dieser Art sind aus der DE 93 05 881 und der US 4 985 004 A bekannt und besitzen einen gestanzten hülsenförmigen Kontaktkörper, der in einem Bereich eine Durchmesserverengung besitzt. Durch die Durchmesserverengung ergibt sich eine Kontaktebene normal zur Achse der Kontakthülse. Je nach gefertigtem Durchmesser und je nach Durchmesser des mit der Kontakthülse zu verbindenden Steckerstiftes ergeben sich so zwei bis vier Undefinierte Kontaktpunkte entlang der Durchmesserverengung. In der Kontakttechnik ist es jedoch stets von großer Bedeutung genau definierte Kontaktpunkte zu haben. So ist beispielweise die Wärmebelastung unterschiedlich, wenn statt vier Kontaktpunkten lediglich zwei zur Verfügung stehen. Die Durchmesserverengung bildet zudem eine innere Wulst, die bei stark verschmutzten Kontakten dazu beiträgt, dass die KontaktSicherheit nicht mehr gegeben ist.Plug devices of this type are known from DE 93 05 881 and US 4 985 004 A and have a stamped, sleeve-shaped contact body which has a diameter constriction in one area. The narrowing of the diameter results in a contact plane normal to the axis of the contact sleeve. Depending on the diameter produced and the diameter of the connector pin to be connected to the contact sleeve, this results in two to four undefined contact points along the narrowing of the diameter. In contact technology, however, it is always very important to have precisely defined contact points. For example, the thermal load is different if only two are available instead of four contact points. The narrowing of the diameter also forms an inner bulge which, in the case of heavily soiled contacts, helps to ensure that contact safety is no longer ensured.
Es sind weiters Kontakthülsen bekannt, die aus vollem Rundmaterial durch Bohren und Schlitzen gefertigt werden. Durch mehrfaches, meist sechsfaches Schlitzen der Hülse werden die Kontaktelemente hergestellt, die durch eine zusätzliche,- separat angebrachte Feder mit radialer Wirkung auf die Federelemente die KontaktSicherheit herstellen. Auch hier stellt sich das Problem der Schaffung einer genau definierten Kontaktzone. Durch den fertigungsbedingten Versatz des Bohrungsdurchmessers in der Kontakthülse und die nicht immer gleiche Position der Schlitze ergeben sich unterschiedliche Federelemente mit inhomogener Wirkungsweise auf den Steckerstift. Ergänzt durch den normalen Verschleiss. während des Steck- und Ziehvorganges ergeben sich hieraus Undefinierte Kontaktpunkte und hohe Kontaktunsicherheiten.Contact sleeves are also known which are manufactured from solid round material by drilling and slitting. The contact elements are produced by multiple, usually six times slitting of the sleeve, which provide contact security by means of an additional, separately attached spring with radial effect on the spring elements. The problem of creating a precisely defined contact zone also arises here. The manufacturing-related offset of the bore diameter in the contact sleeve and the not always the same position of the slots result in different spring elements with an inhomogeneous mode of action on the plug pin. Complemented by normal wear and tear. This results in undefined contact points and high contact uncertainties during the plugging and pulling process.
Weiters sind Kontakthülsen bekannt, deren Grundkörper aus einem vollen Rundmaterial erzeugt wird und eine federnde Kontaktlamelle separat als Stanzteil gefertigt und dem Grundkörper zugeführt wird. Diese Fertigungsart ist jedoch sehr aufwendig in der Herstellung und führt daher zu hohen Herstellungskosten.Furthermore, contact sleeves are known, the base body of which is produced from a full round material and a resilient contact lamella is manufactured separately as a stamped part and the Basic body is fed. However, this type of production is very complex to produce and therefore leads to high production costs.
Es ist daher die Aufgabe der vorliegenden Erfindung eine Kontakthülse der eingangs erwähnten Art vorzuschlagen, die diese Nachteile verhindert, einfach zu fertigen ist und exakt definierte Kontaktpunkte und somit eine sichere Kontaktgabe garantiert, sowie unempfindlich gegen Schmutz ist.It is therefore the object of the present invention to propose a contact sleeve of the type mentioned at the outset which prevents these disadvantages, is easy to manufacture and guarantees precisely defined contact points and thus reliable contact making, and is insensitive to dirt.
Erfindungsgemäß wird dies durch das kennzeichnende Merkmal des Anspruchs 1 erreicht .According to the invention this is achieved by the characterizing feature of claim 1.
Durch die spezielle Ausstellung der Kontaktelemente aus dem Hülsenmantel wird mindestens ein definierter Kontaktpunkt erzeugt, an welchem der elektrische Strom von der Kontakthülse auf den Steckerstift übertragen wird. Durch die Ausstellung von drei Kontaktelementen, ergeben sich folglich drei definierte Kontaktpunkte und es erfolgt zusätzlich eine Zentrierung des Steckerstiftes beim Einschieben desselben.The special display of the contact elements from the sleeve jacket creates at least one defined contact point at which the electrical current is transmitted from the contact sleeve to the plug pin. The display of three contact elements results in three defined contact points and the plug pin is additionally centered when the same is inserted.
Die Verteilung der Kontaktelemente über die Hülse gemäß den kennzeichnenden Merkmalen des Anspruchs 2 ermöglicht eine zusätzliche Verbesserung der Kontaktierung.The distribution of the contact elements over the sleeve according to the characterizing features of claim 2 enables an additional improvement of the contact.
Durch die Erstreckung der Kontaktelemente in axialer Richtung gemäß Anspruch 3 erfolgt während des Einschiebens des Steckerstiftes in die Kontakthülse eine Reinigung der Kontaktzonen. Etwaig vorhandener Schmutz, welcher die Kontaktgabe negativ beeinträchtigen würde, kann somit entfernt werden, bevor die Endposition des Steckerstiftes in der Kontakthülse erreicht ist. Der Führungsabschnitt ermöglicht das leichte Einführen des Steckerstiftes in die Kontakthülse, wobei die Kontaktelemente dabei radial leicht auseinandergedrückt werden.Due to the extension of the contact elements in the axial direction according to claim 3, the contact zones are cleaned during the insertion of the plug pin into the contact sleeve. Any dirt that would adversely affect the contact can thus be removed before the end position of the plug pin in the contact sleeve is reached. The guide section enables the plug pin to be inserted easily into the contact sleeve, with the contact elements being slightly pushed apart radially.
Die Merkmale des Anspruchs 4 ermöglichen eine genaue Zentrierung des Steckerstiftes. Durch die Merkmale des Anspruchs 5 wird auf die Kontaktelemente ein radial nach innen wirkender Druck ausgeübt, durch welchen diese auf das Steckerelement gepresst wird. Dadurch wird gewährleistet, dass auch nach mehrmaligem Einführen und Entfernen des Steckerstiftes in die Kontakthülse die Kontaktelemente ausreichend fest auf den Steckerstift gepresst werden.The features of claim 4 allow precise centering of the connector pin. Due to the features of claim 5, a radially inward pressure is exerted on the contact elements, by means of which pressure is pressed onto the plug element. This ensures that even after repeated insertion and removal of the connector pin in the contact sleeve, the contact elements are pressed sufficiently firmly onto the connector pin.
Die Merkmale des Anspruchs 6 ermöglichen eine einfache und kostengünstige Fertigung.The features of claim 6 enable simple and inexpensive manufacture.
Im Anschluss erfolgt nun eine detaillierte Beschreibung eines Ausführungsbeispiels einer erfindungsgemäßen Kontakthülse. Dabei zeigen:There now follows a detailed description of an embodiment of a contact sleeve according to the invention. Show:

Fig.l zeigt ein einstückiges Stanz- und Biegeteil 1 dessen vorderer Abschnitt zu einem hulsenförmigen Kontaktelement 2 gebogen ist und dessen einer Endbereich einen flach auslaufenden Anschlussteil 3 bildet, der durch zusätzliche Klemmelemente (nicht dargestellt) das Anschließen an den vorgesehenen Leiter ermöglicht. Das hülsenförmige Kontaktelement 2 weist im gezeigten Ausführungsbeispiel zwei in axialer Richtung der Hülse beabstandete Bereiche (Kontaktebenen) 4a, 4b auf, in welchen Teile des Hülsenmantels freigeschnitten bzw. freigestanzt und nach innen gebogen sind und so genau definierte Kontaktelemente 5a-5c,6a-6c (siehe auch Fig.2) bilden. Vorzugsweise sind drei Kontaktelemente vorgesehen. Jedoch können auch ein bzw. mehr als drei Kontaktelemente die definierten Kontaktpunkte bilden. Die Kontaktelemente können durch die Freischneidung bzw. Freistanzung in radialer Richtung der Hülse federn. Jedes einzelne Kontaktelement 5a-5c, 6a-6c weist einen Führungsabschnitt 7a, 7b und eine Kontaktkante 8a, 8b aufFig.l shows a one-piece stamped and bent part 1 whose front section is bent into a sleeve-shaped contact element 2 and one end portion of which forms a flat tapered connecting part 3, which enables connection to the intended conductor by means of additional clamping elements (not shown). In the exemplary embodiment shown, the sleeve-shaped contact element 2 has two regions spaced apart in the axial direction of the sleeve (Contact planes) 4a, 4b, in which parts of the sleeve jacket are cut free or punched out and bent inwards and thus form precisely defined contact elements 5a-5c, 6a-6c (see also FIG. 2). Three contact elements are preferably provided. However, one or more than three contact elements can also form the defined contact points. The contact elements can spring through the free cutting or punching in the radial direction of the sleeve. Each individual contact element 5a-5c, 6a-6c has a guide section 7a, 7b and a contact edge 8a, 8b
(Fig.4) . Der Führungsabschnitt ist in Einsteckrichtung 11 des nicht gezeichneten Steckerstiftes gesehen zuerst angeordnet und weist eine zur Achse der Kontakthülse 2 geneigte und dazu konvergierende Führungskante auf . Die darauffolgende Kontaktkante bildet eine zur Achse der Kontakthülse 2 parallel ausgerichtete Kante. Die im Hülsenmantel ersichtlichen Freischneidungen bzw. Freistanzungen dienen dazu, die Federwirkung der Kontaktelemente 5a-5c,6a-6c in radialer Richtung zu verbessern.(Fig.4). The guide section is first arranged in the insertion direction 11 of the plug pin, not shown, and has a guide edge inclined to the axis of the contact sleeve 2 and converging thereon. The subsequent contact edge forms an edge aligned parallel to the axis of the contact sleeve 2. The clearances or free punchings visible in the sleeve casing serve to improve the spring action of the contact elements 5a-5c, 6a-6c in the radial direction.
Die Kontakthülse 2 weist des weiteren an deren Außenseite im Bereich der nach innen abstehenden Kontaktelemente 5a- 5c,6a-6c jeweils eine über den Umfang der Kontakthülse 2 verlaufende Nut 10a, 10b auf, die zur Aufnahme eines zusätzlichen, ringförmigen Federelementes 9a, b vorgesehen ist .The contact sleeve 2 furthermore has on the outside thereof in the area of the inwardly projecting contact elements 5a-5c, 6a-6c in each case a groove 10a, 10b which extends over the circumference of the contact sleeve 2 and which is provided for receiving an additional annular spring element 9a, b is.
Die Wirkweise der Kontakthülse 2 kann wie folgt beschrieben werden: Beim Einführen des zylindrischen Steckerstiftes (hier nicht dargestellt) trifft die Kuppe des Steckerstiftes auf die Führungskanten 7a der Kontaktelemente 5a-5c und zentriert sich an diesen Kanten, wodurch eine definierte Dreipunktauflage der Kontaktebene 4a erzeugt wird. Mit fortschreitender Eindringtiefe drückt der zylindrische Kontaktstift die einzelnen Kontaktelemente 5a-5c radial auseinander, wobei hier die Kraft des zusätzlichen Federelementes 9a dem Aufweiten als Federkraft entgegen wirkt. Mit Erreichen der geraden Kontaktkante 8a schiebt sich der Kontaktstift unter dauerhafter Druckkraft des zusätzlichen Federelementes 9a achsparallel und linienförmig über die Kontaktkante 8a der Kontaktelemente 5a-5c. Durch das Schieben des Steckerstiftes über die Kontaktelemente 5a-5c erfolgt eine Selbstreinigung der Kontaktkante 8a.The mode of operation of the contact sleeve 2 can be described as follows: When the cylindrical connector pin (not shown here) is inserted, the tip of the connector pin meets the guide edges 7a of the contact elements 5a-5c and is centered on these edges, as a result of which a defined three-point support of the contact plane 4a is created becomes. As the depth of penetration progresses, the cylindrical contact pin radially pushes the individual contact elements 5a-5c apart, the force of the additional spring element 9a counteracting the expansion as a spring force. When the straight contact edge 8a is reached, the contact pin is pushed under permanent pressure of the additional one Spring element 9a parallel to the axis and linearly over the contact edge 8a of the contact elements 5a-5c. By pushing the plug pin over the contact elements 5a-5c, the contact edge 8a is self-cleaning.
Dieser KontaktierungsVorgang wiederholt sich in der nachfolgenden Kontaktebene 4b jedoch mit dem Unterschied, daß die einzelnen Kontaktelemente 6a-6c radial versetzt zu den Kontaktelementen 5a-5c der Kontaktebene 4a angeordnet sind und somit eine völlig unabhängige weitere Kontaktebene darstellen (siehe Fig.2) .This contacting process is repeated in the subsequent contact plane 4b, with the difference that the individual contact elements 6a-6c are arranged radially offset from the contact elements 5a-5c of the contact plane 4a and thus represent a completely independent further contact plane (see FIG. 2).
Fig.5 und Fig.6 zeigen eine alternative Form einer erfindungsgemäßen Kontakthülse. Die Kontaktelemente 5a,5b;6a,6b sind dabei soweit aus dem .Hülsenmantel freigeschnitten, dass dieser in einem Bereich 12 praktisch mit den Kontaktelementen 5a, 5b; 6a, 6b identisch ist. Dies hat neben den bereits erwähnten Vorteilen den zusätzlichen Vorteil einer erhöhten Elastizität der Kontakthülse, was das System unempfindlich gegen nicht exakt passende Steckerstif e macht. Bei den mit 13 gekennzeichneten Stegen handelt es sich um Verdrehsicherungen, welche die erfindungsgemäße Kontakthülse in einer Kammer eines Kunststoffkontaktträgers (nicht gezeichnet) positioniert. 5 and 6 show an alternative form of a contact sleeve according to the invention. The contact elements 5a, 5b; 6a, 6b are cut out of the sleeve casing to such an extent that it is practically in an area 12 with the contact elements 5a, 5b; 6a, 6b is identical. In addition to the advantages already mentioned, this has the additional advantage of increased elasticity of the contact sleeve, which makes the system insensitive to inaccurately fitting plug pins. The webs marked with 13 are anti-rotation devices which position the contact sleeve according to the invention in a chamber of a plastic contact carrier (not shown).
