Abstract

When packaging electrical power cables, consisting of a cable piece on whose one end there is fitted an extruded plug contact, there is a problem in inserting the wire ends into the contact pins arranged on a connector link and the crimping sleeve of an earthing spring. In the past, this was possible only by using manual means. In order to be able to automate this process as well, a retaining bracket extending over the crimping sleeve of the earthing spring is proposed, which has a funnel-shaped insertion opening for a wire end. <IMAGE>

Description

Die Erfindung betrifft einen elektrischen Steckver­binder mit einer Kontaktstifte und eine Erdungsfeder haltenden Steckerbrücke, die nach Anschluß der Adern einer zugeführten elektrischen Leitung unlösbar mit einem Griffkörper umspritzt wird, wobei die Stecker­brücke zwei seitliche Halteböcke zum Halten und Füh­ren der sie umgreifenden Erdungsfeder aufweist und die Erdungsfeder mit einer Krimphülse verbunden ist, die neben einem der Halteböcke angeordnet ist.The invention relates to an electrical connector with a contact pins and a grounding spring-holding plug bridge, which is inextricably molded with a handle body after connecting the wires of a supplied electrical line, the plug bridge having two lateral holding blocks for holding and guiding the grounding spring encompassing it and the grounding spring with a crimp sleeve is connected, which is arranged next to one of the support frames.

Derartige elektrische Steckverbinder, wie sie bei­spielsweise das DE-GM 69 95 96 zeigt, werden in sehr großer Anzahl benötigt. Die Steckerstifte dieser Steckverbinder weisen endseitig eine Längsbohrung zur Aufnahme der Adern der Leitung, im allgemeinen aus Kupferlitze bestehend, auf. Nach Einschieben der Kup­ferlitze werden die Längsbohrungen dann angequetscht, so daß eine sichere Verbindung gegeben ist. Gleiches gilt auch für den Erdungskontakt, der durch eine Er­dungsfeder gebildet ist.Such electrical connectors, as shown for example in DE-GM 69 95 96, are required in very large numbers. The connector pins of these connectors generally have a longitudinal bore at the end for receiving the wires of the line Consisting of copper braid. After inserting the copper wire, the longitudinal holes are then crimped so that a secure connection is given. The same applies to the earth contact, which is formed by an earth spring.

Sämtliche Vorgänge bei der Herstellung solcher konfek­tionierter Anschlußleitungen können automatisiert werden, bis auf das Einführen der Litzenenden in die Einführöffnungen der Steckerstifte beziehungsweise des Erdungskontaktes. Um das Anquetschen durchführen zu können, können die Einführöffnungen nur unwesent­lich größer sein als der Durchmesser der einzufügen­den Leitung, die flexible Leitung muß also sehr genau und gleichachsig in diese Einführöffnung eingeführt werden. Erschwerend wirkt hierbei nicht nur die Flexi­bilität dieser Leitung wie auch der Umstand, daß meh­rere Leitungen in einem Arbeitsgang in die Einführöff­nungen einzuführen sind, sondern insbesondere, daß es sich bei diesen Leitungen um aus einer Vielzahl von Einzeldrähten gebildete Litzen handelt. Wird dieses Litzenende nicht äußerst exakt in die Einführöffnung eingeführt, stößt sich immer einer oder auch mehrere dieser Litzendrähte an der Kante des Steckerstiftes, so daß sie nicht nur nicht in die Einführöffnung ge­langen, sondern nach außen abstehen. Dies bringt die Gefahr mit sich - und das Bestehen dieser Gefahr ist auch bereits durch Todesfälle nachgewiesen - daß die­ser abstehende Draht beziehungsweise diese Drähte an die Außenseite des danach kunststoffumspritzten Steck­verbinders gelangt, wodurch die einen solchen Steck­verbinder ergreifende Person mit dem spannungsführen­den Draht in Berührung kommt. Um diese Gefahr zu ver­meiden ist auch bereits bekannt geworden, eine die Steckerstifte umschließende Kappe vorzusehen, die nach außen abstehende Litzendrähte in das Innere des Steckverbinders zurückdrängen soll, um auf jeden Fall das Durchdringen der Kunststoffummantelung durch einen abstehenden Litzendraht zu vermeiden. Das Auf­bringen der Kappe ist jedoch wiederum nur manuell mög­lich und daher teuer. Außerdem können dann immer noch einzelne, von den dicht beieinanderliegenden Stecker­stiften abstehende Drähte sich gegenseitig berühren und einen Kurzschluß und damit zumindest einen Aus­fall der Anschlußleitung verursachen.All processes in the manufacture of such prefabricated connecting lines can be automated, except for the insertion of the strand ends into the insertion openings of the plug pins or the ground contact. In order to be able to carry out the crimping, the insertion openings can only be insignificantly larger than the diameter of the line to be inserted, so the flexible line must be inserted into this insertion opening very precisely and coaxially. This is aggravated not only by the flexibility of this line, but also by the fact that several lines can be inserted into the insertion openings in one operation, but in particular that these lines are strands formed from a large number of individual wires. If this strand end is not inserted extremely precisely into the insertion opening, one or more of these strand wires always bumps against the edge of the plug pin, so that they not only do not get into the insertion opening but protrude outwards. This brings with it the danger - and the existence of this danger has already been proven by deaths - that this protruding wire or these wires reaches the outside of the connector which is then encapsulated in plastic, as a result of which the person gripping such a connector comes into contact with the live wire. In order to avoid this danger, it has also become known to provide a cap which encloses the connector pins and which is to push back outwardly projecting stranded wires into the interior of the connector, in any case to prevent the plastic sheathing from penetrating through a protruding stranded wire. However, the cap can only be applied manually and is therefore expensive. In addition, individual wires protruding from the connector pins that are close together can still touch each other and cause a short circuit and thus at least a failure of the connecting line.

Um diesem Mißstand abzuhelfen, ist es bereits bekannt­geworden, die abisolierten Litzenenden zu verdrillen. Durch dieses Verdrillen der Litzendrähte besteht we­sentlich weniger die Gefahr, daß einzelne Litzen­drähte abstehen und beim Einführen in die Einführöff­nung der Steckerstifte nach außen abgebogen werden können. Diese Maßnahme hat jedoch den Nachteil, daß die Quetschverbindung nicht mit genügender Festigkeit durchgeführt werden kann. Um zu einer sicheren und festen Quetschverbindung zu kommen, sollten die Lit­zendrähte unverdrillt sein.In order to remedy this situation, it has already become known to twist the stripped wire ends. This twisting of the stranded wires means that there is substantially less danger that individual stranded wires protrude and can be bent outwards when inserted into the insertion opening of the plug pins. However, this measure has the disadvantage that the crimp connection cannot be carried out with sufficient strength. In order to achieve a secure and firm crimp connection, the stranded wires should be untwisted.

Eine Erleichterung beim Einführen der Litzenenden ist durch das DE-GM 85 11 857 gegeben, das Einführöffnun­gen der Steckerstifte zeigt, die an der Einführmün­dung mit einem kleinen angeprägten Trichter versehen sind. Diese trichterförmige Einführöffnung ist jedoch so kurz und die Trichterwandung so steil zur Einführ­richtung geneigt, daß die oben beschriebene Gefahr keinesfalls damit behoben ist.DE-GM 85 11 857 makes it easier to insert the ends of the strands, which shows insertion openings in the connector pins, which are provided with a small embossed funnel at the insertion mouth. However, this funnel-shaped insertion opening is so short and the funnel wall is inclined so steeply to the insertion direction that the danger described above is by no means eliminated.

Die Erfindung hat sich die Aufgabe gestellt, das auto­matische Einführen von aus vielen Einzeldrähten be­stehenden Litzen in die Krimphülse der Erdungsfeder zu ermöglichen. Erreicht wird dies nach der Erfindung dadurch, daß der an der Steckerbrücke befindliche Haltebock einstückig mit einem über die Krimphülse der Erdungsfeder ausladenden Quersteg verbunden ist, der gleichachsig mit der Krimphülse eine zur Außen­seite offene, konusförmige Aussparung aufweist. Vor­teilhafterweise wird die Aussparung nach der Erfin­dung doppelkonusförmig ausgeführt, so daß die Krimp­hülse in den ihr benachbarten Konus eingreifen kann.The object of the invention is to enable the automatic insertion of strands consisting of many individual wires into the crimp sleeve of the grounding spring. This is achieved according to the invention in that the bracket located on the connector bridge is made in one piece with one over the crimp sleeve is connected to the crossbar that extends out of the grounding spring and has a conical recess that is open to the outside and coaxial with the crimp sleeve. Advantageously, the recess is double-cone-shaped according to the invention, so that the crimp sleeve can engage in the cone adjacent to it.

Beim Eindrücken der Erdungsfeder in die Steckerbrücke gelangt die Krimphülse dieser Erdungsfeder in den Be­reich des der Steckerbrücke benachbarten Konus und wird durch diesen Konus zentriert und gehalten. Über dieser nun in eindeutiger Lage fixierten Krimphülse befindet sich sodann der jenseitige Konus, der als Einführungstrichter für das Litzenende gilt, also die Einzeldrähte dieser Litze beim Einführen sicher in diese Krimphülse hineinführt. Da der Quersteg über den einen Haltebock direkt mit der Steckerbrücke, in der die Steckerstifte eingespritzt sind, verbunden ist, liegt die relative Lage dieser Einführöffnungen von den Steckerstiften und der Krimphülse der Erdungs­feder zueinander fest, so daß nunmehr ohne Schwierig­keiten die abisolierten Litzenenden beziehungsweise Leitungsadern in diese festliegenden Einführungsöff­nungen eingeführt und nach dem Einführen angequetscht werden können. Zum Stande der Technik ist hier das DE-GM 70 13 139 zu nennen, das einen in einem Stecker­unterteil eingefügten Steckerstift zeigt, der durch ein Steckeroberteil, das Stromleitereinführbohrungen aufweist, abgedeckt ist. Diese Einführbohrungen die­nen aber keinesfalls dazu, das Einführen der Adern zu erleichtern, sondern sind durch das Aufsetzen des Steckeroberteils bedingt.When the earthing spring is pressed into the connector bridge, the crimp sleeve of this earthing spring reaches the area of the cone adjacent to the connector bridge and is centered and held by this cone. Above this crimp sleeve, which is now fixed in a clear position, is the cone on the other side, which serves as an insertion funnel for the end of the strand, that is to say when the individual wires of this strand are inserted securely into this crimp sleeve. Since the crossbar is directly connected to the connector bridge in which the connector pins are injected, the relative position of these insertion openings of the connector pins and the crimp sleeve of the grounding spring is fixed to one another, so that the stripped wire ends or wire conductors are now in without difficulty these fixed insertion openings can be inserted and crimped after insertion. In relation to the state of the art, DE-GM 70 13 139 should be mentioned here, which shows a plug pin inserted in a lower part of the plug, which is covered by an upper part of the plug which has current conductor insertion bores. These insertion holes do not serve to facilitate the insertion of the wires, but are caused by the top part of the connector.

Der Quersteg hat jedoch nicht nur den Vorteil, daß er die Krimphülse der Erdungsfeder in eine eindeutige Lage relativ zu den Einführöffnungen der Steckerstif­ te bringt, sondern daß nunmehr auch diese Krimphülse in ihrer Lage fixiert ist. Dies ist deshalb wichtig, weil beim Umspritzen des Steckverbinders die ein­schießende Kunstsstoffmasse die aus verhältnismäßig dünnem Material bestehende Krimphülse der Erdungs­feder, obwohl sie bereits mit ihrer Litze verbunden ist, umdrücken und somit in eine nicht mehr kontrol­lierbare Lage bringen kann. Diese Gefahr ist nunmehr behoben, da die Krimphülse sicher in ihrem Konus des Querstegs fixiert ist. Besteht die Gefahr des Um­drückens der Krimphülse nicht, und ist gewährleistet, daß die Krimphülse tatsächlich gleichachsig zu der Aussparung liegt, so kann selbstverständlich auf die der Krimphülse benachbarte konusförmige Aussparung verzichtet werden.The crossbar, however, has not only the advantage that it places the crimp sleeve of the earth spring in a clear position relative to the insertion openings of the plug pin te brings, but that now this crimp sleeve is fixed in its position. This is important because when the connector is encapsulated, the plastic mass that shoots in can crimp the earthing spring's crimp sleeve, which is made of relatively thin material, even though it is already connected to its strand, and can thus bring it into an uncontrollable position. This danger has now been eliminated since the crimp sleeve is securely fixed in its cone of the crosspiece. If there is no risk of the crimp sleeve being pushed over, and it is ensured that the crimp sleeve is actually coaxial with the recess, the conical recess adjacent to the crimp sleeve can of course be dispensed with.

Um auf jeden Fall zu vermeiden, daß sich Litzendrähte an der Stirnfläche der in ihrem Konus festgelegten Krimphülse der Erdungsfeder stoßen können, soll der Durchmesser der Engstelle zwischen den beiden Konen geringfügig kleiner sein als der Innendurchmesser der Krimphülse. Außerdem empfiehlt es sich, da die Krimp­hülse aus gegenüber der Litze verhältnismäßig festem Material ist, den Konus, in den die Krimphülse ein­greift, kürzer und mit einem steileren Flankenwinkel zu formen als den jenseitigen Konus, der als Einfüh­rungstrichter für die Litzenenden dient.In order to prevent stranded wires from bumping against the end face of the crimp sleeve of the earthing spring fixed in its cone, the diameter of the constriction between the two cones should be slightly smaller than the inside diameter of the crimp sleeve. In addition, since the crimp sleeve is made of a material that is relatively strong compared to the strand, it is advisable to shape the cone in which the crimp sleeve engages shorter and with a steeper flank angle than the cone on the other side, which serves as an insertion funnel for the strand ends.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt.In the drawing, an embodiment of the subject matter of the invention is shown schematically.

In eine Steckerbrücke (1) sind Steckerstifte (2) ein­geformt, die jenseits mit ihren Einführöffnungen (3) über die Steckerbrücke (1) hinausragen. Angeformt an die Steckerbrücke (1) sind zwei Halteböcke (4, 5), die eine Erdungsfeder (6) halten und führen. Der eine Haltebock (5) kann noch, wie strichpunktiert (7) ange­deutet, eine Erdungs-Kontakthülse aufweisen.Plug pins (2) are formed in a plug bridge (1) and protrude beyond them with their insertion openings (3) over the plug bridge (1). Molded onto the connector bridge (1) are two retaining brackets (4, 5) that hold and guide an earthing spring (6). One bracket (5) can also have an earthing contact sleeve, as indicated by dash-dotted lines (7).

Am Haltebock (4) ist ein Quersteg (8) angeformt mit einer doppelkonusförmigen Aussparung (9, 10). Beim Eindrücken der Erdungsfeder (6) durch einen Durch­bruch in der Steckerbrücke (1) gelangt eine Krimp­hülse (11) der Erdungsfeder (6) in den Bereich des Konus (10), wodurch sie zentriert und gehalten wird.A crossbar (8) with a double-cone-shaped recess (9, 10) is formed on the support bracket (4). When the earthing spring (6) is pressed in through an opening in the connector bridge (1), a crimp sleeve (11) of the earthing spring (6) reaches the area of the cone (10), as a result of which it is centered and held.

In diesen so vormontierten Steckverbinder können nun die Litzenenden eingeführt werden. Hinsichtlich der in die Krimphülse (11) des Erdungskontaktes (6) einzu­führenden Litzen ist festzustellen, daß die Litzen durch den Konus (9), der hier als Einführungstrichter dient, sicher in die Krimphülse (11) hineingeführt und dort angequetscht werden können. Außerdem ist nun­mehr die Lage dieser Krimphülse (11) festgelegt, so daß auch durch starken Druck der einschießenden Kunst­stoffmasse zum Umspritzen dieses so gebildeten Steck­verbinders ein Verschieben der Krimphülse nicht mehr zu befürchten ist.The stranded ends can now be inserted into this pre-assembled connector. With regard to the strands to be inserted into the crimp sleeve (11) of the grounding contact (6), it should be noted that the strands can be securely inserted into the crimp sleeve (11) and crimped there through the cone (9), which serves here as an insertion funnel. In addition, the position of this crimp sleeve (11) is now fixed, so that there is no longer any fear of displacement of the crimp sleeve due to the high pressure of the plastic compound to be molded around this connector.
