Definitions
- the invention relates to a connector according to the preamble of claim 1.
- Such connectors with a screw connection of the plug part to the socket part for securing against unintentional loosening of the plug connection are known in manifold designs, for example by the miniature circular connector with screw closure type "RKMWV " from Lumberg GmbH. This fuse also works permanently as long as the connector is not exposed to any or only slight or slow movements. However, if the plug connection is subject to a large number of in particular periodic impacts or a shaking movement, there is a great risk that the screw connection will loosen and the purpose of the union nut will no longer be fulfilled.
- Such connectors are not suitable, for example, for use on machines with permanent vibration, such as use on machine valves.
- Screw connections are already known in which a nut is secured against unscrewing due to shocks or vibrations by means of a spring washer (snap ring or corrugated spring washer).
- the spring washer is always arranged between a contact surface of the screw and the end face of the nut facing it and is therefore necessarily designed as a separate part that can be lost when the screw connection is loosened, with all the disadvantages associated therewith, starting with the more complex storage and assembly on site up to the known problem that this part is often not at hand when needed.
- the invention is therefore based on the object of developing a connector of the type mentioned in the simplest and cheapest possible manner in such a way that at the same time a high vibration resistance and an uncomplicated screwing of the union nut to the thread of the associated mating connector part is ensured.
- the polygon is preferably an octagon, which enables the contact carrier to be produced easily.
- two cams are preferably provided on the union nut, which are arranged offset by 180 ° on the inner circumference of the union nut.
- the polygon is a nine-corner, wherein three cams are advantageously used, which are arranged at 120 ° on the inner circumference of the union nut.
- the part of the contact carrier facing away from the plug-side end part can be overmolded in a conventional manner with an injection molded housing, with the union nut being able to be placed loosely on the contact carrier before the overmolded material in the inventive configuration of the contact carrier and the union nut. This saves an additional step, namely pressing the union nut onto the contact carrier.
- the union nut is preferably made from a die casting or with a cold impact tool.
- the contact carrier is usually made of plastic.
- the edges of the polygon are rounded to make it easier to turn the union nut with respect to the contact carrier. As a result, the degree of locking action between the contact carrier and the union nut can be selected.
- the cams on the union nut are preferably designed to be elastic in order to facilitate rotation of the union nut with respect to the contact carrier.
- the plug connector 1 consists of an injection molded housing 2 with a cable entry part 3 on the connection side, a contact carrier 6 made of plastic containing four contacts 5 and protruding from the housing 2, and a union nut 7 comprising the contact carrier 6.
- the union nut 7 preferably has an internal thread 8 that can be screwed to a mating connector part, not shown, which has an adapted external thread, in order to hold the connector 1 together with the mating connector.
- a shoulder 9 of the union nut engages behind an annular collar 10 of the contact carrier, so that the union nut 7 is rotatably arranged so that it cannot be lost.
- the union nut has two projections or cams 11 which extend radially inwards from the inner circumference of the shoulder 9.
- the contact carrier 6 has an upper end part 14 which extends from the ring collar 10 in the direction of the housing 2 and into it, and a lower end or plug part 16 which extends from the ring collar 10 in the direction of the mating connector, not shown.
- the upper end part 14 of the contact carrier 6 is designed as a polygon, or here as an octagon with eight edge surfaces 18. During a rotation of the union nut 7 with respect to the contact carrier 6, therefore, a locking effect occurs on the edge surfaces 18 between adjacent edges or corners 19 of the contact carrier 6 and the cams 11 of the union nut 7.
- the number of corners of the polygon and thus the flat edge surfaces 18 and the number of cams 11 can be freely selected. It is also possible to use a nine-corner in connection with three cams, the cams being provided at 120 ° from one another on the inner circumference of the shoulder of the union nut.
- the corners of the polygon can be rounded, as indicated in FIG. 2, and / or the cams 11 on the inner circumference of the shoulder 9 of the union nut 7 and / or the contact carrier 6 can be made elastic be.
- the lower end or plug part 16 of the contact carrier 6 is preferably round, but can have any shape that matches the mating connector.
- the union nut 7 can preferably be loosely placed on the upper end part 14 before the contact carrier 6 is encapsulated, so that the union nut does not have to be pressed on from the connector part side 16 until afterwards in an additional operation.
- the previously used shaft washers for securing the screw connection can be omitted, since this is ensured by the locking of the cams 11 on the union nut 7 with the side edges 18 of the contact carrier.

Abstract
Description
Die Erfindung betrifft einen Steckverbinder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a connector according to the preamble of
Derartige Steckverbinder mit einer Verschraubung des Steckerteils mit dem Buchsenteil zur Sicherung gegen unbeabsichtigtes Lösen der Steckverbindung sind in mannigfacher Ausführung, beispielsweise durch den Miniaturrundsteckverbinder mit Schraubverschluß Typ "RKMWV..." der Firma Lumberg GmbH, bekannt. Diese Sicherung funktioniert auch dauerhaft, solange die Steckverbindung keinen oder nur geringen bzw. langsamen Bewegungen ausgesetzt ist. Unterliegt die Steckverbindung jedoch einer Vielzahl von insbesondere periodischen Stößen bzw. einer Rüttelbewegung so ist die Gefahr groß, daß sich die Verschraubung löst und damit der Zweck der Überwurfmutter nicht mehr erfüllt ist. Beispielsweise für die Verwendug an Maschinen mit permanenten Schwingung, wie etwa einem Einsatz an Maschinenventilen, sind solche Steckverbinder nicht geeignet.Such connectors with a screw connection of the plug part to the socket part for securing against unintentional loosening of the plug connection are known in manifold designs, for example by the miniature circular connector with screw closure type "RKMWV ..." from Lumberg GmbH. This fuse also works permanently as long as the connector is not exposed to any or only slight or slow movements. However, if the plug connection is subject to a large number of in particular periodic impacts or a shaking movement, there is a great risk that the screw connection will loosen and the purpose of the union nut will no longer be fulfilled. Such connectors are not suitable, for example, for use on machines with permanent vibration, such as use on machine valves.
Es sind bereits Schraubverbindungen bekannt, bei denen eine Mutter durch eine Federscheibe (Sprengring oder gewellte Federscheibe) gegen Aufdrehen aufgrund von Stößen bzw. Schwingungen gesichert sind. Die Federscheibe ist dabei stets zwischen einer Anlagefläche der Schraube und der dieser zugewandten Stirnfläche der Mutter angeordnet und daher notwendigerweise als separates, bei gelöster Schraubverbindung verlierbares Teil ausgebildet und zwar mit allen damit verbundenen Nachteilen, angefangen von der aufwendigeren Lagerhaltung und Montage vor Ort bis hin zu dem bekannten Problem, daß dieses Teil häufig bei Bedarf nicht zur Hand ist.Screw connections are already known in which a nut is secured against unscrewing due to shocks or vibrations by means of a spring washer (snap ring or corrugated spring washer). The spring washer is always arranged between a contact surface of the screw and the end face of the nut facing it and is therefore necessarily designed as a separate part that can be lost when the screw connection is loosened, with all the disadvantages associated therewith, starting with the more complex storage and assembly on site up to the known problem that this part is often not at hand when needed.
Im deutschen Gebrauchsmuster G 93 01 171.7 ist eine Schraubverbindung beschrieben, bei der an einem Kontaktträger eine Radialverzahnung ausgebildet ist, die mit korrespondierenden Verzahnungen einer Überwurfmutter zusammen wirkt. Dadurch soll ein ungewolltes Lösen einer Verschraubung verhindert werden. Die Fertigung von Teilen mit Radialverzahnung ist jedoch aufwendig, da auch relativ enge Toleranzen eingehalten werden müssen.In the German utility model G 93 01 171.7 a screw connection is described in which on a contact carrier a radial toothing is formed, which interacts with corresponding teeth of a union nut. This is to prevent an unintentional loosening of a screw connection. However, the production of parts with radial toothing is complex since relatively narrow tolerances must also be observed.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Steckverbinder der eingangs genannten Art auf möglichst einfache und kostengünstige Weise derart weiterzubilden, daß zugleich eine hohe Rüttelsicherheit und eine unkomplizierte Verschraubung der Überwurfmutter mit dem Gewinde des zugehörigen Gegensteckverbinderteils gewährleistet ist.The invention is therefore based on the object of developing a connector of the type mentioned in the simplest and cheapest possible manner in such a way that at the same time a high vibration resistance and an uncomplicated screwing of the union nut to the thread of the associated mating connector part is ensured.
Diese Aufgabe ist durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is solved by the characterizing features of
Durch die Ausbildung eines Vielecks an einem Ende des Kontaktträgers und eines nach innen gerichteten Vorsprungs oder Nockens an der Überwurfmutter entsteht eine Verrastung zwischen dem Kontaktträger und der Überwurfmutter nach dem Aufschrauben der Überwurfmutter auf das Gewinde des zugehörigen Gegensteckverbinders. Somit ist eine hohe Verdrehsicherheit gegeben und damit wird ein Lösen aufgrund von Rüttelbewegungen weitgehend vermieden.The formation of a polygon at one end of the contact carrier and an inward projection or cam on the union nut results in a latching between the contact carrier and the union nut after the union nut has been screwed onto the thread of the associated mating connector. This ensures a high degree of security against rotation and thus largely prevents loosening due to shaking movements.
Darüberhinaus ist die erfindungsgemäße Ausbildung des Kontaktträgers sowie der Überwurfmutter äußerst einfach und eine zusätzliche Federscheibe für diesen Zweck nicht erforderlich.In addition, the inventive design of the contact carrier and the union nut is extremely simple and an additional spring washer is not required for this purpose.
Vorteilhafte Ausgestaltungen des erfindungsgemäßen Steckverbinders sind den Unteransprüchen entnehmbar.Advantageous embodiments of the connector according to the invention can be found in the subclaims.
Vorzugsweise ist das Vieleck ein Achteck, das eine leichte Herstellung des Kontaktträgers ermöglicht. Bei der Verwendung eines Achtecks sind vorzugsweise zwei Nocken an der Überwurfmutter vorgesehen, die um 180° versetzt am Innenumfang der Überwurfmutter angeordnet sind.The polygon is preferably an octagon, which enables the contact carrier to be produced easily. In the Using an octagon, two cams are preferably provided on the union nut, which are arranged offset by 180 ° on the inner circumference of the union nut.
Bei einer Ausführungsform ist das Vieleck ein Neuneck, wobei vorteilhafter Weise drei Nocken verwendet werden, die um 120° am Innenumfang der Überwurfmutter angeordnet sind.In one embodiment, the polygon is a nine-corner, wherein three cams are advantageously used, which are arranged at 120 ° on the inner circumference of the union nut.
Der dem steckseitigen Endteil abgewandte Teil des Kontaktträgers ist in herkömmlicher Weise mit einem Spritzgußgehäuse umspritzbar, wobei bei der erfindungsgemäßen Ausgestaltung des Kontaktträgers und der Überwurfmutter die Überwurfmutter vor dem Umspritzten lose auf dem Kontaktträger plazierbar ist. Dadurch wird ein zusätzlicher Arbeitsgang, nämlich das Aufdrücken der Überwurfmutter auf den Kontaktträger eingespart.The part of the contact carrier facing away from the plug-side end part can be overmolded in a conventional manner with an injection molded housing, with the union nut being able to be placed loosely on the contact carrier before the overmolded material in the inventive configuration of the contact carrier and the union nut. This saves an additional step, namely pressing the union nut onto the contact carrier.
Vorzugsweise ist die Überwurfmutter aus einem Druckguß oder mit einem Kaltschlagwerkzeug gefertigt.The union nut is preferably made from a die casting or with a cold impact tool.
Der Kontaktträger besteht üblicherweise aus Kunststoff.The contact carrier is usually made of plastic.
Um das Drehen der Überwurfmutter bezüglich des Kontaktträgers zu erleichtern, sind die Kanten des Vielecks abgerundet. Dadurch ist der Grad der Rastwirkung zwischen dem Kontaktträger und der Überwurfmutter wählbar. Vorzugsweise sind die Nocken an der Überwurfmutter elastisch ausgebildet, um eine Verdrehung der Überwurfmutter bezüglich des Kontaktträgers zu erleichtern.The edges of the polygon are rounded to make it easier to turn the union nut with respect to the contact carrier. As a result, the degree of locking action between the contact carrier and the union nut can be selected. The cams on the union nut are preferably designed to be elastic in order to facilitate rotation of the union nut with respect to the contact carrier.

Unter Bezugnahme auf die Fig. 1 bis 4 wird ein bevorzugtes Ausführungsbeispiel des Steckverbinders 1 der vorliegenden Erfindung beschrieben.A preferred embodiment of the
Der Steckverbinder 1 besteht aus einem Spritzgußgehäuse 2 mit anschlußseitigem Kabeleinführungsteil 3, einem vier Kontakte 5 enthaltenden, aus dem Gehäuse 2 herausragenden Kontaktträger 6 aus Kunststoff sowie einer den Kontaktträger 6 umfassenden Überwurfmutter 7.The
Die Überwurfmutter 7 weist vorzugsweise ein Innengewinde 8 auf, daß mit einem ein angepaßtes Außengewinde aufweisenden, nicht dargestellten Gegensteckverbinderteil verschraubt werden kann, um den Steckverbinder 1 mit dem Gegensteckverbinder zusammenzuhalten. Beim Verschrauben der Überwurfmutter 7 mit dem Gegensteckverbinder hintergreift eine Schulter 9 der Überwurfmutter einen Ringbund 10 des Kontaktträgers, so daß die Überwurfmutter 7 unverlierbar drehbar angeordnet ist. Ferner weist die Überwurfmutter zwei Vorsprünge oder Nocken 11 auf, die sich radial vom Innenumfang der Schulter 9 nach innen erstrecken.The union nut 7 preferably has an
Der Kontaktträger 6 besitzt ein oberes Endteil 14, das sich von dem Ringbund 10 in Richtung des Gehäuses 2 und in dieses hinein erstreckt, sowie einen unteren End- oder Steckerteil 16, der sich von dem Ringbund 10 in Richtung des nicht dargestellten Gegensteckverbinders erstreckt.The
Der obere Endteil 14 des Kontaktträgers 6 ist als Vieleck, bzw. hier als Achteck mit acht Kantenflächen 18, ausgebildet. Während einer Verdrehung der Überwurfmutter 7 bezüglich des Kontaktträgers 6 tritt daher auf den Kantenflächen 18 zwischen benachbarten Kanten oder Ecken 19 des Kontaktträgers 6 und den Nocken 11 der Überwurfmutter 7 eine Rastwirkung auf.The
Es sei bemerkt, daß die Anzahl der Ecken des Vielecks und somit der planen Kantenflächen 18 sowie die Anzahl der Nocken 11 frei gewählt werden kann. Hierbei ist auch eine Verwendung eines Neunecks in Verbindung mit drei Nocken möglich, wobei die Nocken um 120° voneinander versetzt am Innenumfang der Schulter der Überwurfmutter vorgesehen sind.It should be noted that the number of corners of the polygon and thus the
Um die Verdrehung der Überwurfmutter 7 bezüglich des Kontaktträgers 6 zu erleichtern, können die Ecken des Vielecks, wie in Fig. 2 angedeutet ist, abgerundet und/oder die Nocken 11 am Innenumfang der Schulter 9 der Überwurfmutter 7 und/oder der Kontaktträger 6 elastisch ausgebildet sein.In order to facilitate the rotation of the union nut 7 with respect to the
Der untere End- oder Steckerteil 16 des Kontaktträgers 6 ist vorzugsweise rund ausgebildet, kann jedoch jede Form aufweisen, die mit dem Gegensteckverbinder zusammenpaßt.The lower end or
Vorzugsweise kann die Überwurfmutter 7 vor dem Umspritzen des Kontaktträgers 6 lose auf den oberen Endteil 14 gesteckt werden, so daß die Überwurfmutter nicht erst danach in einem zusätzlichen Arbeitsgang von der Steckerteilseite 16 her aufgedrückt werden muß. Desgleichen können die früher verwendeten Wellenscheiben zur Sicherung der Verschraubung entfallen, da diese durch die Verrastung der Nocken 11 an der Überwurfmutter 7 mit den Seitenkanten 18 des Kontaktträgers sichergestellt wird.The union nut 7 can preferably be loosely placed on the
