Abstract

The electrical coupling unit (K) has a mechanical steady support, which has insertion holes running parallel to each other. The insertion holes are connected in mounting position at the striped ends of cable (1), which surrounds an insulation that forms a protective body around the connection side of the support. The halting flaps (11) are fixed at the connector sides of the support (5), which are locked with each other in the mounting position from the injection molding of protective body (14) closely on the insulation of the conductor (2,3) and damp proof pressure locks the support.

Description

Die Erfindung bezieht sich auf ein elektrisches Kupplungsteil zum Anbringen an einer elektrischen Leitung, bestehend aus einem mechanisch stabilen Träger aus Isoliermaterial, der mindestens zwei parallel zueinander verlaufende Durchgangslöcher zur Aufnahme von elektrischen Kontaktteilen aufweist, die in Montageposition an die abisolierten Enden von elektrischen Leitern angeschlossen sind, von denen jeder von einer Isolierung umgeben ist, bei welchem in Montageposition um das leitungsseitige Ende des Trägers ein sich bis über die mit einem die Leiter umschließenden Mantel aus Isoliermaterial ausgerüstete Leitung erstreckender, durch Spritzgießen erzeugter Schutzkörper aus Isoliermaterial herumgeformt ist ( DE 36 23 927 C1 ).The invention relates to an electrical coupling part for attachment to an electrical line, consisting of a mechanically stable carrier made of insulating material having at least two mutually parallel through holes for receiving electrical contact parts, which are connected in the mounting position to the stripped ends of electrical conductors each of which is surrounded by an insulation, in which in the mounting position around the line-side end of the carrier is formed around over the with a conductor enclosing jacket of insulating material equipped line extending, produced by injection molding protection body made of insulating material ( DE 36 23 927 C1 ).

"Kupplungsteil" im Sinne der Erfindung können ein Stecker mit Steckerstiften oder eine Dose mit Dosenkontakten sein. "Kontaktteile" sind dann also entweder die Steckerstifte oder die Dosenkontakte. Neben Konstruktionen, bei denen diese Kontaktteile fest in Isolierstoffträgern verankert sind, gibt es Anordnungen, bei denen die Kontaktteile in Durchgangslöcher von vorgefertigten Trägern aus Isoliermaterial eingesetzt werden. Die aus Kostengründen meist sehr einfach, beispielsweise aus Blechstreifen, geformten Kontaktteile sind mit einem Rastelement ausgerüstet, durch welches sie nach dem Einsetzen in ein Durchgangsloch des Trägers gegen axiale Verschiebung gesichert sind. Die Kontaktteile füllen allerdings nicht die ganze lichte Weite der Durchgangslöcher aus, sondern sie sitzen relativ locker in denselben. Beim Spritzen des Schutzkörpers ist dessen Material relativ dünnflüssig und es wird mit hohem Druck in die Spritzform eingebracht. Wenn die Anschlußseite des Trägers nicht besonders gestaltet wird oder andere Maßnahmen getroffen werden, tritt das Spritzmaterial leicht in die Durchgangslöcher und auch in die Kontaktteile ein, die dann für eine Kontaktgabe nicht mehr brauchbar sind. Ein entsprechendes Kupplungsteil müßte also entweder mit großem Aufwand nachbearbeitet oder als Ausschuß fortgeworfen werden."Coupling" in the context of the invention may be a plug with pins or a box with can contacts. "Contact parts" are then either the connector pins or the can contacts. In addition to constructions in which these contact parts are firmly anchored in Isolierstoffträgern, there are arrangements in which the contact parts are inserted into through holes of prefabricated carriers made of insulating material. The reasons of cost usually very simple, such as metal strips, shaped contact parts are equipped with a locking element, by which they are secured after insertion into a through hole of the carrier against axial displacement. However, the contact parts do not fill the entire width of the through holes, but they sit relatively loosely in the same. When spraying the protective body whose material is relatively thin and it is introduced at high pressure in the mold. If the terminal side of the carrier is not specially designed or other measures are taken, the spray material easily enters the through holes as well as the contact parts, which are then for contact are no longer usable. A corresponding coupling part would therefore either be reworked with great effort or thrown away as a committee.

Bei dem Kupplungsteil nach der DE 34 17 811 C1 wird vor dem Spritzen des Schutzkörpers auf die der Leitung zugewandte Fläche des Trägers ein Heißschmelzkleber aufgebracht, der in erwärmtem Zustand gut fließfähig ist und bei Berührung mit Raumtemperatur aufweisenden, kalten Teilen schlagartig in einen nicht fließfähigen Zustand übergeht. Der Heißschmelzkleber kann dadurch nur bis zu den Kontaktteilen gelangen, jedoch nicht mehr in die Durchgangslöcher eindringen. Die Durchgangslöcher sind auf diese Weise fest durch den erstarrten Heißschmelzkleber verschlossen. Das Material des nach dem Aufbringen des Heißschmelzklebers gespritzten Schutzkörpers kann weder in die Durchgangslöcher des Trägers noch in die Kontaktteile eindringen. Dieses bekannte Verfahren hat sich in der Praxis bewährt, insbesondere bei Kupplungsteilen mit größeren Abmessungen.In the coupling part after the DE 34 17 811 C1 a hot melt adhesive is applied before the spraying of the protective body on the surface of the carrier facing the line, which is readily flowable in the heated state and abruptly passes into a non-flowable state on contact with room temperature, cold parts. The hot melt adhesive can thereby reach only up to the contact parts, but no longer penetrate into the through holes. The through holes are firmly closed in this way by the solidified hot melt adhesive. The material of the sprayed after applying the hot melt adhesive protection body can penetrate neither into the through holes of the carrier nor in the contact parts. This known method has proven itself in practice, especially in coupling parts with larger dimensions.

Die eingangs erwähnte DE 36 23 927 C1 beschreibt ein Kupplungsteil, bei welchem vor Festlegung der Leiter an den Kontaktteilen auf die Enden aller Leiter aus Kunststoff bestehende Rohrstücke aufgeschoben werden, deren Innendurchmesser zumindest teilweise geringfügig kleiner als der Außendurchmesser der isolierten Leiter ist und deren Außendurchmesser zumindest teilweise geringfügig größer als die lichte Weite der Durchgangslöcher ist. Die Rohrstücke werden bei oder nach dem Einstecken der Kontaktteile in die Durchgangslöcher auf den Leitern verschoben und in die Durchgangslöcher eingeschoben. Durch die Rohrstücke, welche die Leiter fest und dicht umgeben, werden die Durchgangslöcher des Trägers auf der Anschlußseite dicht verschlossen, da sie gegenüber den Durchgangslöchern ein geringes Übermaß haben und dadurch fest an der Wandung derselben anliegen. Beim Spritzgießen des Schutzkörpers kann daher auch bei dieser Abdichtmethode kein Spritzmaterial in die Durchgangslöcher eintreten. Auch dieses bekannte Verfahren hat sich in der Praxis bewährt, insbesondere bei Kupplungsteilen für Leitungen mit einer größeren Anzahl von Leitern.The initially mentioned DE 36 23 927 C1 describes a coupling member in which prior to fixing the conductor to the contact parts on the ends of all plastic conductors existing pipe pieces are pushed, whose inner diameter is at least partially slightly smaller than the outer diameter of the insulated conductors and whose outer diameter at least partially slightly larger than the inside diameter of the Through holes is. The pipe pieces are moved at or after the insertion of the contact parts in the through holes on the conductors and inserted into the through holes. By the pipe sections which surround the conductors tightly and tightly, the through holes of the carrier are sealed on the connection side, since they have a small excess compared to the through holes and thereby firmly abut against the wall of the same. In the case of injection molding of the protective body, therefore, even with this sealing method, no spray material can enter the through holes. Also, this known method has been proven in practice, especially in coupling parts for cables with a larger number of conductors.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs geschilderte Kupplungsteil so zu gestalten, daß die Abdichtung der Durchgangslöcher und der in dieselben eingesetzte Kontaktteile vereinfacht ist, insbesondere bei Kupplungsteilen mit kleineren Abmessungen.The invention has for its object to make the above-described coupling part so that the sealing of the through holes and the contact parts used in the same is simplified, especially in coupling parts with smaller dimensions.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß am leitungsseitigen Ende des Trägers zwei schwenkbar mit demselben verbundene Rastklappen angebracht sind, die in Montageposition vor dem Spritzgießen des Schutzkörpers unter dichter Anlage an der Isolierung der Leiter miteinander verrastet sind und den Träger druck- und feuchtigkeitsdicht verschließen.This object is achieved according to the invention in that at the line end of the carrier two pivotally mounted with the same latching flaps are mounted, which are locked together in the mounting position prior to injection molding of the protective body under close contact with the insulation of the conductors and the carrier pressure and moisture-tight close.

Dieses Kupplungsteil ist mit einem Träger ausgerüstet, der alle für eine wirksame Abdichtung seiner Durchgangsbohrungen erforderlichen Teile selbst aufweist. Zusätzliche Teile und/oder Materialien werden nicht benötigt. Das Kupplungsteil kann dadurch insbesondere auch kleinere Abmessungen haben. Die am Träger angebrachten und mit demselben beispielsweise über Filmscharniere verbundenen Rastklappen sind in Montageposition fest miteinander verrastet. Sie umschließen dabei die isolierten Leiter so fest, daß ein hermetisch dichter Verschluß erreicht ist. Es besteht damit ein druck- und feuchtigkeitsdichter Abschluß des Trägers. Beim Spritzgießen des Schutzkörpers kann dessen Material somit nicht in den Träger, insbesondere nicht in dessen Durchgangslöcher eintreten und somit nicht bis zu den in denselben befindlichen Kontaktteilen gelangen. Durch den Einsatz der Rastklappen und deren feste Verrastung in Montageposition ist der Träger auch für unterschiedliche Leiterdurchmesser (über deren Isolierung) einsetzbar.This coupling part is equipped with a carrier which has all the parts required for effective sealing of its through holes itself. Additional parts and / or materials are not needed. The coupling part can thereby also have smaller dimensions. The attached to the carrier and associated with the same, for example via film hinges latching flaps are firmly locked together in the mounting position. They enclose the insulated conductors so tightly that a hermetically sealed closure is achieved. There is thus a pressure and moisture-tight closure of the carrier. In injection molding of the protective body, therefore, its material can not enter the carrier, in particular its through-holes, and thus can not reach the contact parts located in the same. Through the use of the latching flaps and their fixed locking in the mounting position of the carrier for different conductor diameter (on the insulation) can be used.

In Fig. 1 ist schematisch ein Schnitt durch ein Kupplungsteil K dargestellt, das am Ende einer elektrischen Leitung 1 angebracht ist. Die Leitung 1 hat im dargestellten Ausführungsbeispiel zwei isolierte elektrische Leiter 2 und 3, die gemeinsam von einem Mantel 4 der aus Isoliermaterial umgeben sind. Zum Kupplungsteil K gehört ein Träger 5 aus mechanisch stabilem Isoliermaterial, wie beispielsweise Polyamid, der zwei parallel zueinander verlaufende Durchgangslöcher 6 und 7 hat. In den Durchgangslöchern 6 und 7 sind elektrische Kontaktteile 8 und 9 angeordnet, die mit den an ihren Enden abisolierten Leitern 2 und 3 elektrisch leitend verbunden sind. Die Leitung 1 kann auch mehr als zwei Leiter aufweisen. Die Anzahl der Durchgangslöcher im Träger 5 richtet sich nach der Anzahl der Leiter.In Fig. 1, a section through a coupling part K is schematically shown, which is attached to the end of an electrical line 1. The line 1 has in the illustrated embodiment, two insulated electrical conductors 2 and 3, which are surrounded together by a jacket 4 of insulating material. To the coupling part K includes a support 5 of mechanically stable insulating material, such as polyamide, which has two mutually parallel through holes 6 and 7. In the through holes 6 and 7 electrical contact parts 8 and 9 are arranged, which are electrically conductively connected to the stripped conductors 2 and 3 at their ends. The line 1 may also have more than two conductors. The number of through holes in the carrier 5 depends on the number of conductors.

Am Träger 5 sind gemäß Fig. 2, die einen gegenüber Fig. 1 um 90° versetzten Schnitt durch das Kupplungsteil K zeigt, zwei Rastklappen 10 und 11 schwenkbar angebracht. Sie können beispielsweise über Filmscharniere 12 und 13 mit dem Träger 5 verbunden sein. In Montageposition sind die beiden Rastklappen 10 und 11 fest miteinander verrastet. Sie liegen in dieser Position dicht und fest an den Isolierungen der Leiter 2 und 3 an. Um das leitungsartige Ende des Trägers 5 ist ein durch Spritzgießen erzeugter Schutzkörper 14 aus Isoliermaterial, wie beispielsweise Polyamid, herumgeformt, der sich bis über den Mantel 4 der Leitung 1 erstreckt.On the carrier 5, two latching flaps 10 and 11 are pivotally mounted as shown in FIG. 2, which shows a comparison with FIG. 1 offset by 90 ° section through the coupling part K. For example, they can be connected to the carrier 5 via film hinges 12 and 13. In the mounting position, the two locking flaps 10 and 11 are firmly locked together. They are in this position tightly and firmly on the insulation of the conductors 2 and 3 at. To the line-like end of the carrier 5, a protective body 14 produced by injection molding of insulating material, such as polyamide, is formed, which extends over the jacket 4 of the line 1.

Fig. 3 zeigt eine Seitenansicht des Trägers 5 mit daran angebrachten Rastklappen 10 und 11 in ihrer Offenstellung. Eine der Rastklappen kann beispielsweise an zwei Seiten mit einem Haken 15 (Fig. 4, linke Seite) ausgerüstet sein, während die andere Rastklappe dann an beiden Seiten seitwärts abstehende Zapfen 16 (Fig. 4, rechte Seite) aufweist. Die beiden Rastklappen 10 und 11 können jede auch auf einer Seite einen Haken 15 und auf der anderen Seite einen Zapfen 16 haben.Fig. 3 shows a side view of the carrier 5 with attached latching flaps 10 and 11 in its open position. One of the latching flaps may be equipped, for example, on two sides with a hook 15 (Fig. 4, left side), while the other latching flap then has on both sides laterally projecting pins 16 (Fig. 4, right side). The two locking flaps 10 and 11 can each have a hook 15 on one side and a pin 16 on the other side.

In der aus Fig. 5 ersichtlichen Montageposition greifen die Haken 15 über die Zapfen 16, so daß die beiden Rastklappen 10 und 11 fest miteinander verrastet sind. In den in dieser Darstellung erkennbaren Löchern 17 und 18 sind im fertigen Kupplungsteil K die Leiter 2 und 3 angebracht.In the apparent from Fig. 5 mounting position, the hooks 15 engage over the pins 16, so that the two locking flaps 10 and 11 are firmly locked together. In the in recognizable holes 17 and 18 are in the finished coupling part K, the conductors 2 and 3 attached.

Die Rastklappen 10 und 11 sind gemäß Fig. 4 an ihren zur Anlage an den Isolierungen der Leiter 2 und 3 bestimmten Enden mit halbkreisförmigen Vertiefungen 19 und 20 ausgerüstet, welche in Montageposition mit einer ihrer ganzen Länge entsprechenden Fläche fest an die Isolierungen der Leiter 2 und 3 angepreßt werden.The latching flaps 10 and 11 are shown in FIG. 4 at their intended to rest against the insulation of the conductors 2 and 3 ends with semicircular recesses 19 and 20, which in the mounting position with an entire length corresponding surface fixed to the insulation of the conductors 2 and 3 are pressed.

Das Kupplungsteil K wird beispielsweise wie folgt hergestellt:The coupling part K is produced, for example, as follows:

Die beiden Leiter 2 und 3 werden durch Entfernen des Mantels 4 am Ende der Leitung 1 auf vorgegebener Länge freigelegt. Danach werden die Enden der Leiter 2 und 3 abisoliert und die Kontaktteile 8 und 9 werden elektrisch leitend an denselben festgelegt. Die Kontaktteile 8 und 9 werden anschließend in die Durchgangslöcher 6 und 7 des Trägers 5 eingesteckt. Daraufhin werden die beiden Rastklappen 10 und 11 bis zur Anlage an den Leitern 2 und 3 gebracht und miteinander verrastet, wobei deren Haken 15 über ihre Zapfen 16 greifen. Das so vorbereitete Leitungsende mit hermetisch abgedichtetem Träger 5 wird abschließend in ein Spritzgießwerkzeug eingelegt, in welchem der Schutzkörper 14 um dasselbe herumgespritzt wird. Nach dessen Abkühlung kann das fertige, am Ende der Leitung 1 angebrachte Kupplungsteil K aus dem Spritzgießwerkzeug entnommen werden.The two conductors 2 and 3 are exposed by removing the jacket 4 at the end of the line 1 to a predetermined length. Thereafter, the ends of the conductors 2 and 3 are stripped and the contact parts 8 and 9 are electrically conductively fixed thereto. The contact parts 8 and 9 are then inserted into the through holes 6 and 7 of the carrier 5. Then the two latching flaps 10 and 11 are brought to rest on the ladders 2 and 3 and locked together, with their hooks 15 engage over their pin 16. The thus prepared line end with hermetically sealed carrier 5 is finally inserted into an injection mold, in which the protective body 14 is injected around the same. After cooling, the finished, attached to the end of the line 1 coupling part K can be removed from the injection mold.
