Description

Die Erfindung betrifft einen Steckverbinder mit einem Kontaktelement für die Erdung und Abschirmung aus einem elektrisch leitenden Werkstoff in Form einer Hülse mit zylindrischer Gestalt, welches ein oberes Segment mit einem äußeren Kontaktbereich der mit einer Kontakthilfe versehen ist, und ein unteres Segment aufweist. Das Kontaktelement ist zum Einsatz in eine übliche Steckverbindung, wie sie für Leistungskabel sowie Daten- und Steuerleitungen in der Nachrichten-, Steuerungs-, Meß- und Regeltechnik verwandt wird, bestimmt.The invention relates to a connector with a contact element for grounding and shielding made of an electrically conductive material in the form of a sleeve with a cylindrical shape, which has an upper segment with an outer contact area which is provided with a contact aid, and a lower segment. The contact element is intended for use in a conventional plug connection, as is used for power cables and data and control lines in communications, control, measurement and regulation technology.

Ein solchen Steckverbinden ist aus dem Dokument GB-A-1 166 166 bereits bekannt.Such a connector is already known from document GB-A-1 166 166.

Kabel werden heutzutage häufig mit Abschirmungen versehen. Für Leitungen mit einer Spannung von mehr als 42 V ist zudem eine Schutzerdung zwingend erforderlich. Die Schirmung oder Schutzerdung in einem Steckverbinder erfolgt dadurch, daß bei Durchgang des Kabels durch einen üblichen metallischen Steckverbinder die Abschirmung oder Leitung mit einer in dem Steckverbinder vorhandenen Kontakthülse leitend verbunden wird. Die Kontakthülse ihrerseits steht in leitendem Kontakt mit dem Steckverbindungsgehäuse.Nowadays, cables are often provided with shields. Protective earthing is also mandatory for cables with a voltage of more than 42 V. The shielding or protective grounding in a plug connector is achieved in that when the cable passes through a conventional metallic plug connector, the shield or line is conductively connected to a contact sleeve present in the plug connector. The contact sleeve in turn is in conductive contact with the connector housing.

Herkömmliche Kontakthülsen für Steckverbinder geben in zweierlei Hinsicht Anlaß zu Problemen. Zum einen liegen diese Probleme auf fertigungstechnischem Gebiet; die Kontakthülsen sind vielfach kompliziert und erfordern relativ viele Arbeitsgänge zur Herstellung. Zum anderen ergeben sich häufig Probleme in den Kontaktbereichen, die durch schlechten Sitz und/oder Korrosion oder aus Platzgründen nur einen schlechten Kontakt zwischen der Kontakthülse und dem Körper der Steckverbindung ergeben.Conventional contact sleeves for connectors give rise to problems in two ways. On the one hand, these problems lie in the area of manufacturing technology; the contact sleeves are often complicated and require a relatively large number of operations for the production. On the other hand, problems often arise in the contact areas, which result in poor contact and / or corrosion or, for reasons of space, only poor contact between the contact sleeve and the body of the plug connection.

Der Erfindung liegt die Aufgabe zugrunde, Kontakthülsen bereitzustellen, die einfach und kostengünstig herzustellen sind und guten Sitz und Kontakt ermöglichen.The invention has for its object to provide contact sleeves that are simple and inexpensive to manufacture and allow good fit and contact.

Dieses Ziel wird erfindungsgemäß mit einem Kontaktelement der eingangs geschilderten Art erreicht, bei dem das untere Segment einen zungenförmigen Anschlußbereich aufweist.This goal is achieved according to the invention with a contact element of the type described in the introduction, in which the lower segment has a tongue-shaped connection area.

Das erfindungsgemäße Kontaktelement ist einstückig gefertigt und besteht aus einem elektrisch leitenden Werkstoff. Bevorzugt ist die Fertigung des Kontaktelements aus einem elektrisch gut leitenden Metall, beispielsweise aus Kupfer, Aluminium sowie Legierungen des Kupfers oder Aluminiums.The contact element according to the invention is made in one piece and consists of an electrically conductive material. The contact element is preferably made from an electrically highly conductive metal, for example from copper, aluminum and alloys of copper or aluminum.

Das Kontaktelement hat im allgemeinen die Form einer Hülse oder eines Ringes, die bzw. der in die üblichen, kommerziell vertriebenen Steckverbindungen, insbesondere in Rundsteckverbinder, eingesetzt werden können und darin durch ihre Paßform gegen unerwünschte Bewegung gesichert sind. Die Kontakthülse hat für die üblicherweise auf dem Markt zu findenden Rundsteckverbinder eine zylindrische Form.The contact element generally has the shape of a sleeve or a ring which can be used in the customary, commercially available plug connections, in particular in circular connectors, and are secured therein against undesired movement by their fit. The contact sleeve has a cylindrical shape for the circular connectors usually found on the market.

Die Kontakthülse besteht aus einem oberen Segment mit einem Kontaktbereich, über den der Kontakt mit dem metallischen Steckverbinder hergestellt wird, sowie einem unteren Segment mit einem Anschlußbereich, an dem die elektrische Leitung zur Erdung oder die Abschirmung angeschlossen wird. Das zu erdende oder abzuschirmende Kabel wird dabei von unten, d.h. von der Anschlußbereichsseite, an die Kontakthülse herangeführt, um mit den einzelnen Adern zu den Kontaktstellen des Steckverbinders geführt zu werden.The contact sleeve consists of an upper segment with a contact area, via which contact is made with the metallic connector, and a lower segment with a connection area, to which the electrical line for grounding or the shielding is connected. The cable to be earthed or shielded is from below, ie from the Connection area side, brought up to the contact sleeve to be guided with the individual wires to the contact points of the connector.

Der Kontaktbereich befindet sich im oberen Segment der Kontakthülse und ist mit einer Kontakthilfe versehen, d.h. mit einer Oberflächenbeschaffenheit, die den Kontakt zwischen Kontakthülse und Steckverbindung fördert. Hierzu dient eine Aufrauhung zumindest eines Teils der Außenfläche der Hülse. Vorzugsweise umschließt der Kontaktbereich die Hülse am unteren Ende des oberen Segments, jedoch sind auch andere Anordnungen möglich, etwa eine ringförmige Anordnung am oberen Ende des oberen Segments oder in Form von senkrechten streifenförmigen Erhebungen, die das obere Segment in regelmäßigen Abständen umgeben. Zur Förderung des Kontakts - als Kontakthilfe - kann der Kontaktbereich als Rändel, Kordel oder Körnung ausgebildet sein, so daß die erhabenen Stellen als Kontaktpunkte zum Gehäuse der Steckverbindung dienen. Es ist auch möglich, daß gesamte obere Segment mit einer Oberflächenbeschaffenheit auszustatten, die den Kontakt zur Steckverbindung fördert, beispielsweise mit einer Körnung.The contact area is located in the upper segment of the contact sleeve and is provided with a contact aid, i.e. with a surface texture that promotes contact between the contact sleeve and plug connection. This is done by roughening at least part of the outer surface of the sleeve. The contact area preferably surrounds the sleeve at the lower end of the upper segment, but other arrangements are also possible, for example an annular arrangement at the upper end of the upper segment or in the form of vertical strip-shaped elevations which surround the upper segment at regular intervals. To promote contact - as a contact aid - the contact area can be designed as a knurl, cord or grain, so that the raised areas serve as contact points to the housing of the plug connection. It is also possible to equip the entire upper segment with a surface condition which promotes contact with the plug connection, for example with a grit.

Das untere Segment der Kontakthülse, das etwa die Hälfte der Höhe des gesamten Hülsenkörpers ausmacht, weist einen Anschlußbereich für die Erdung oder Abschirmung auf. Dieser Anschlußbereich ist zungenförmig gestaltet, so daß der Leiter durch Aufschieben einer herkömmlichen Kontaktklemme oder durch Anlöten daran befestigt werden kann. Die Abmessungen der Anschlußzunge entsprechen denen üblicher Kontaktklemmen.The lower segment of the contact sleeve, which makes up about half the height of the entire sleeve body, has a connection area for grounding or shielding. This connection area is tongue-shaped so that the conductor can be attached to it by sliding on a conventional contact terminal or by soldering. The dimensions of the connecting tongue correspond to those of conventional contact terminals.

Vorzugsweise ist die Anschlußzunge durch Einschnitte im unteren Segment ausgebildet, d.h. zwei Einschnitte im unteren Segment definieren die Anschlußzunge hinsichtlich ihrer Breite und Länge.The connecting tongue is preferably formed by cuts in the lower segment, ie two cuts in the lower segment define the connecting tongue in terms of its width and length.

Alternativ kann das gesamte untere Segment der Kontakthülse als Anschlußbereich ausgebildet sein, d.h. das untere Segment besteht unter Fortfall eines großen Teils des unteren Segmentringes lediglich aus der Anschlußzunge. Aus fertigungstechnischen Gründen ist diese Ausführungsform jedoch weniger bevorzugt, da die Herstellung mehr Fertigungsschritte erfordert.Alternatively, the entire lower segment of the contact sleeve can be designed as a connection area, i.e. the lower segment consists of a large part of the lower segment ring only from the connecting tongue. For manufacturing reasons, however, this embodiment is less preferred since the production requires more manufacturing steps.

Um die Einpassung der Kontakthülse in die Steckverbindung zu erleichtern, kann das obere Segment mit einem Einschnitt versehen sein. Dieser Einschnitt hat beispielsweise eine Weite von 1 bis 3 mm und reicht gemäß einer Ausführungsform bis zum Kontaktbereich. Er kann an beliebiger Stelle der Kontakthülse angeordnet sein. Zum Ausgleich von Spannungen kann der Einschnitt an seinem unteren Ende verrundet sein oder in eine kreisförmige Ausstanzung einmünden, die beispielsweise einen Radius aufweist, der einer halben bis einer ganzen Einschnittweite entspricht. Gemäß einer weiteren Ausführungsform weist die Kontakthülse einen sich über die ganze Länge erstreckenden Schlitz oder Einschnitt auf. In diesem Fall befindet sich der Schlitz oder Einschnitt jedoch nicht notwendig in dem Hülsenbereich, der die Anschlußzunge aufweist, sondern kann gegen die Anschlußzunge um 90 bis 270° versetzt sein.In order to facilitate the fitting of the contact sleeve into the plug connection, the upper segment can be provided with an incision. This incision has a width of 1 to 3 mm, for example, and in one embodiment extends to the contact area. It can be arranged at any point on the contact sleeve. To compensate for tensions, the incision can be rounded at its lower end or open into a circular punched-out area which, for example, has a radius that corresponds to half to an entire incision width. According to a further embodiment, the contact sleeve has a slot or incision extending over the entire length. In this case, however, the slot or incision is not necessarily in the sleeve region which has the connecting tongue, but can be offset from the connecting tongue by 90 to 270 °.

Schließlich kann die Anschlußzunge zur Erleichterung des Festlötens der Abschirmung oder elektrischen Leitung eine Lochung oder Ausstanzung aufweisen, die vorzugsweise von runder oder in Längsrichtung der Zunge elliptischer Form ist.Finally, in order to facilitate the soldering of the shielding or electrical line, the connecting tongue can have a perforation or punched-out section, which is preferably round or elliptical in the longitudinal direction of the tongue.

Fig. 1 zeigt eine Ausführungsform des erfindungsgemäßen Kontaktelements in seitlichem Aufriß. Das Element, das vorzugsweise aus einer Kupferlegierung gefertigt ist, besteht aus einer Hülse 1 mit einem oberen Segment (11) mit dem Kontaktbereich (12) und einem unteren Segment (13) mit der Anschlußzunge (15). Zur Anpassung an eine übliche Rundsteckerverbindung ist der Durchmesser des unteren Segments geringfügig kleiner als der des oberen Segments, so daß ein Rücksprung (18) entsteht. Die hierdurch bedingte bessere Paßform ermöglicht einen besseren Kontakt zwischen Rundsteckerverbinder und Kontakthülse. Desweiteren ist das obere Segment (11) an seinem oberen Ende zur besseren Einführung des Elements in das Steckergehäuse und Führung des Kabels einwärts gebogen.Fig. 1 shows an embodiment of the contact element according to the invention in side elevation. The element, which is preferably made of a copper alloy, consists of a sleeve 1 with an upper segment (11) with the contact area (12) and a lower segment (13) with the connecting tongue (15). To adapt to a conventional round plug connection, the diameter of the lower segment is slightly smaller than that of the upper segment, so that a recess (18) is created. The resulting better fit enables better contact between the circular connector and the contact sleeve. Furthermore, the upper segment (11) is bent inwards at its upper end in order to better insert the element into the plug housing and guide the cable.

Am unteren Rand des oberen Segments befindet sich die als Rändel ausgeführte Kontakthilfe (14), deren Riffelung einen besseren Kontakt zwischen dem Körper des Steckverbinders und der Kontakthülse ermöglicht.At the lower edge of the upper segment is the knurled contact aid (14), the corrugation of which enables better contact between the body of the connector and the contact sleeve.

Die Anschlußzunge (15) ist an ihrem unteren Ende gerundet, was das Aufschieben einer herkömmlichen Kontaktklemme oder eines Kontaktschuhs erleichtert. Seitlich wird die Zunge (15) durch die Einschnitte (16a und 16b) in das untere Segment definiert. Die längliche elliptische Aussparung (17) soll das Anlöten des elektrischen Leiters erleichtern, falls eine Lötverbindung gewünscht ist.The connecting tongue (15) is rounded at its lower end, which makes it easier to slide on a conventional contact clamp or contact shoe. The tongue (15) is defined laterally by the incisions (16a and 16b) in the lower segment. The elongated elliptical recess (17) is to facilitate the soldering of the electrical conductor if a soldered connection is desired.

Fig. 2 zeigt eine zweite Ausführungsform des erfindungsgemäßen Kontaktelements. Gemäß dieser Ausführungsform besteht das untere Segment (13) lediglich aus der Zunge (15) mit der Ausstanzung (17); der in Fig. 1 vorhandene zylindrische Teil des unteren Segments wurde abgeschnitten.Fig. 2 shows a second embodiment of the contact element according to the invention. According to this embodiment, the lower segment (13) consists only of the tongue (15) with the punched out (17); the cylindrical part of the lower segment shown in FIG. 1 was cut off.

Fig. 3 zeigt eine weitere Ausführungsform, die weitgehend mit der in Fig. 1 gezeigten übereinstimmt. Unterschiede bestehen hinsichtlich Form und Länge der Zunge (15), die breiter und weniger gerundet ausgeführt ist und somit für eine andere Form von Kontaktklemme oder Kontaktschuh ausgelegt ist. Die Lochung oder Ausstanzung in dieser Ausführungsform ist kreisförmig.FIG. 3 shows a further embodiment, which largely corresponds to that shown in FIG. 1. Differences exist with regard to the shape and length of the tongue (15), which is made wider and less rounded and is therefore designed for a different form of contact clamp or contact shoe. The perforation or punching in this embodiment is circular.

Fig. 4 zeigt eine Variante der in Fig. 3 gezeigten Ausführungsform, in der das untere Segment (13) auf den zungenförmigen Anschlußbereich (15) reduziert ist.Fig. 4 shows a variant of the embodiment shown in Fig. 3, in which the lower segment (13) is reduced to the tongue-shaped connection area (15).

Fig. 5 zeigt einen Rundsteckverbinder (2) in teilweise aufgeschnittenen Zustand mit eingesetzter Kontakthülse (1). Der Rundsteckverbinder (2) besteht aus einem Körper (21), der an seinem oberen Ende mit einer Überwurf- oder Kupplungsmutter (22) versehen ist und an seinem unteren Ende eine Einführungsverschraubung (23) aufweist, durch die das Kabel in die Verbindung eingeführt und festgesetzt wird. Die Kontakthülse (1) ist in das Innere des Körpers (21) mit Hilfe einer Fassung (24) eingepaßt. Die Fassung (24) wird in den Körper (1) eingeschraubt und dient als Fassung für den Isolierträger der Kontakte des Kabels. Der Kontaktbereich (12), der als Rändel (14) ausgeführt ist, steht dabei in leitendem Kontakt mit der Metallfassung (24) für den Isolierträger.Fig. 5 shows a circular connector (2) in a partially cut state with inserted contact sleeve (1). The circular connector (2) consists of a body (21) which is provided at its upper end with a union or coupling nut (22) and has an insertion screw connection (23) at its lower end, through which the cable is inserted into the connection and is fixed. The contact sleeve (1) is fitted into the interior of the body (21) with the aid of a socket (24). The socket (24) is screwed into the body (1) and serves as a socket for the insulating support of the contacts of the cable. The contact area (12), which is designed as a knurl (14), is in conductive contact with the metal frame (24) for the insulating support.

Das von unten in die gezeigte Rundsteckverbindung einzuführende Kabel wird über die Anschlußzunge (15) der Hülse (1) damit leitend verbunden; die einzelnen Adern des Kabels verlassen die Rundsteckverbindung durch die Hülse (1), die Fassung (24) für den Isolierträger und die Verschraubung (22), um zu den einzelnen Kontaktstellen geführt zu werden.The cable to be inserted from below into the circular connector shown is conductively connected to it via the connecting tongue (15) of the sleeve (1); the individual wires of the cable leave the circular connector through the sleeve (1), the socket (24) for the insulating support and the screw connection (22) in order to be led to the individual contact points.

Fig. 6 bis 8 zeigen Varianten für den Ausschnitt X in Fig. 1 bis 4. Dabei ist gemäß Fig. 6 das obere Segment (11) von oben her mit einem senkrechten Einschnitt versehen, der kurz vor Erreichen des Kontaktbereichs (12) endet. Gemäß Fig. 7 mündet der Einschnitt in eine kreisförmige Ausstanzung; gemäß Fig. 8 reicht der Einschnitt über den Ausschnitt X im oberen Segment (11) hinaus und erstreckt sich über die gesamte Länge der Hülse; die Hülse ist also über ihre gesamte Länge aufgeschnitten.6 to 8 show variants for the cutout X in FIGS. 1 to 4. According to FIG. 6, the upper segment (11) is provided with a vertical incision from above, which ends shortly before the contact region (12) is reached. According to FIG. 7, the incision opens into a circular punching out; 8, the incision extends beyond the cutout X in the upper segment (11) and extends over the entire length of the sleeve; the sleeve is thus cut over its entire length.

In Fig. 1 bis 4 zeigt Y einen Ausschnitt des Kontaktbereichs des Kontaktelements, der in allen vier Fällen als Rändel ausgeführt ist. Alternativ kann dieser Kontaktbereich aber auch als Kordel oder in Form einer unregelmäßigen Körnung ausgebildet sein. Es versteht sich, daß sich der Kontaktbereich ringförmig um den gesamten Zylinder erstreckt.1 to 4, Y shows a section of the contact area of the contact element, which is designed as a knurl in all four cases. Alternatively, this contact area can also be designed as a cord or in the form of an irregular grain. It is understood that the contact area extends in a ring around the entire cylinder.

Fig. 9 zeigt einen erfindungsgemäßen Steckverbinder in Gesamtdarstellung, wobei die einzelnen Teile auseinandergezogen gezeigt sind. Der Steckverbinder wird derart zusammengebaut, daß die in Fig. 9 gezeigten Einzelteile in der angegebenen Reihenfolge ineinander geschoben bzw. verschraubt werden.Fig. 9 shows a connector according to the invention in an overall view, the individual parts being shown pulled apart. The connector is assembled in such a way that the individual parts shown in FIG. 9 are pushed or screwed into one another in the order specified.

Die einzelnen elektrisch leitenden Durchführungen 25 des Steckverbinders werden in bekannter Weise mit elektrischen Zuleitungen verbunden. Der Zusammenbau des Steckverbinders erfolgt so, daß zunächst die Überwurfmutter 22 über die Fassung 24 geschoben wird, wo sie gegen einen Anschlag 24' stößt. Die Kontakthülse 1 wird dann in Fig. 9 von unten in die Fassung 24 geschoben. Dabei kommt der Kontaktbereich 12 der Hülse 1 in guten elektrischen Kontakt mit der Fassung 24. In Fig. 5 ist dieser gute elektrische Kontakt nicht deutlich gezeigt, um die einzelnen Bauteile zeichnerisch auseinanderhalten zu können. In Wirklichkeit stößt die Kontakthilfe 14 direkt gegen die Hülse 24.The individual electrically conductive bushings 25 of the connector are connected to electrical leads in a known manner. The connector is assembled so that the union nut 22 is first pushed over the socket 24, where it abuts a stop 24 '. The contact sleeve 1 is then pushed into the socket 24 from below in FIG. 9. The contact area 12 of the sleeve 1 comes into good electrical contact with the socket 24. This good electrical contact is not clearly shown in FIG. 5 in order to be able to distinguish the individual components from one another in the drawing. In reality, the contact aid 14 bumps directly against the sleeve 24.

Sodann wird der Körper 21 über die Hülse 1 geschoben und mit seinem Innengewinde 21' auf einem Außengewinde 24'' der Hülse 24 verschraubt. Dabei drückt ein Anschlag 21'' des Körpers 21 die Hülse 1 gegen einen elektrisch leitenden Anschlag (in Fig. 5 nicht gezeichnet) der Fassung 24, so daß die Fassung 24, die Hülse 1 und der Körper 21 in gutem elektrischen Kontakt miteinander stehen.The body 21 is then pushed over the sleeve 1 and screwed with its internal thread 21 'onto an external thread 24' 'of the sleeve 24. A stop 21 ″ of the body 21 presses the sleeve 1 against an electrically conductive stop (not shown in FIG. 5) of the socket 24, so that the socket 24, the sleeve 1 and the body 21 are in good electrical contact with one another.

Schließlich wird ein Gummiring 26 von unten in den Körper 21 geschoben, wobei der Gummiring 26 beidseits durch metallische Ringe 27, 28 abgedeckt ist. Eine Verschraubung 23 wird von unten in ein Innengewinde 21''' verschraubt, so daß eine Leitung mit einer Vielzahl von elektrischen Andern in den Steckverbinder eingeführt werden kann.Finally, a rubber ring 26 is pushed into the body 21 from below, the rubber ring 26 being covered on both sides by metallic rings 27, 28. A screw connection 23 is screwed from below into an internal thread 21 ″ ″, so that a line with a large number of electrical connectors can be inserted into the connector.
