Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Steckverbinders einer wasserdichten Steckverbindung, welcher eine oder mehrere über einen Crimpanschluß mit einer elektrischen Leitung verbundene Steckerelemente umfaßt, die mit in einem Gegensteckverbinder gelagerten Steckerelementen zusammensteckbar sind, und welcher in seinem rückwärtigen, den Steckerelementen abgewandten Bereich ein von einer die elektrischen Leitungen wasserdicht umschließenden Umspritzung gebildetes Gehäuseteil aufweist, wobei zur Herstellung dieser Umspritzung die Steckerelemente in eine Form eingelegt werden, deren Formhohlraum unter Anlage der Ränder der beiden Formhälften an den jeweiligen Crimpungen der Steckerelemente abgedichtet wird, wobei die Ränder der beiden Formhälften den Crimpungen der Steckerelemente entsprechende Ausnehmungen aufweisen. Weiters betrifft die Erfidnung einen Steckerverbinder einer wasserdichten Steckverbindung, welcher eine oder mehrere über einen Crimpanschluß mit einer elektrischen Leitung verbundene Steckerelemente umfaßt, die mit in einem Gegensteckverbinder gelagerten Steckerelementen zusammensteckbar sind, und welcher in seinem rückwärtigen, den Steckerelementen abgewandten Bereich ein von einer die elektrischen Leitungen wasserdicht umschließenden Umspritzung gebildetes Gehäuseteil aufweist, wobei diese Umspritzung unmittelbar an die jeweiligen Crimpungen der Steckerelemente angrenzt, vorzugsweise diese umgibt.The invention relates to a method for producing a connector of a waterproof Plug connection, which one or more via a crimp connection comprising plug elements connected to an electrical lead, the can be plugged together with plug elements mounted in a mating connector are, and which in its rear, the connector elements facing away Area one of one the electrical lines waterproof enclosing Encapsulation formed housing part, wherein for the preparation of this Encapsulation the connector elements are inserted into a mold whose Mold cavity under conditioning of the edges of the two mold halves to the respective Crimping of the connector elements is sealed, the edges of the two mold halves the crimps of the connector elements corresponding recesses exhibit. The invention further relates to a plug connector of a waterproof connector, which one or more via a crimp connection comprising plug elements connected to an electrical line, which can be plugged together with plug elements mounted in a mating connector are, and which in its rear, the connector elements facing away Area one of one the electrical lines waterproof enclosing Encapsulation has formed housing part, said encapsulation directly adjacent to the respective crimps of the connector elements, preferably this surrounds.

Bei wasserdichten Steckverbindungen wird beim Einschieben eines Steckerteils in ein Steckeraufnahmeteil eine wasserdichte Verbindung herkömmlicher Weise dadurch hergestellt, daß das Steckeraufnahmeteil mit einer um dessen Gehäuse umlaufenden Dichtung ausgestattet ist und das Steckerteil einen die Dichtung des Steckeraufnahmeteils im zusammengesteckten Zustand übergreifenden Fortsatz mit geschlossener Mantelfläche aufweist, wobei die Dichtung dicht an der Innenseite dieses Fortsatzes anliegt. Weiters müssen das Steckeraufnahmeteil und das Steckerteil gegen ein Eindringen von Wasser entlang der Leitungen abgedichtet werden. Hierfür ist es bekannt, auf die Leitungen aufgeschobene Dichtungsringe zu verwenden, die in hohlzylindrische Ausnehmungen im Gehäuse des Steckeraufnahmeteils bzw. des Steckerteils in den Bereichen, in denen die elektrischen Leitungen aus dem entsprechenden Gehäuse treten, dichtend zwischen Gehäuse und Leitung eingedrückt werden. Nachteilig an dieser Art Dichtung zwischen Gehäuse und Leitungen ist der Platzbedarf für die Dichtungsringe, wodurch, insbesondere im Falle von mehreren Kontaktstiften bzw. Kontaktbuchsen und somit mehreren Leitungen, die Baugröße der Steckverbindung wesentlich vergrößert wird.For watertight plug connections is when inserting a plug part in a plug receiving part, a waterproof connection of conventional manner manufactured by the fact that the plug receiving part with a to the housing is equipped with circumferential seal and the plug part a the seal of the Plug receiving part in the assembled state cross-extension having a closed lateral surface, wherein the seal is close to the inside this extension rests. Furthermore, the plug receiving part and the plug part sealed against ingress of water along the lines become. For this purpose, it is known, pushed onto the lines of sealing rings to use in hollow cylindrical recesses in the housing the plug receiving part or the plug part in the areas where the electrical wires from the corresponding housing, sealing between Housing and line are pressed. A disadvantage of this type of seal between housing and lines is the space required for the sealing rings, whereby, in particular in the case of a plurality of contact pins or contact sockets and thus multiple lines, the size of the connector is essential is enlarged.

Weiters ist bekannt, zur Abdichtung der elektrischen Leitungen diese mit einer Umspritzung zu versehen. Im Falle eines Steckerteils kann diese Umspritzung von der elektrischen Leitung bis zum rückwärtigen Teil des Steckerstiftes reichen, so daß in diesem Fall im wesentlichen das gesamte Gehäuse des Steckerteils von einer derartigen Umspritzung gebildet werden kann. Bei einem Steckeraufnahmeteil ist es dagegen notwendig, die Steckerbuchse beim Umspritzen gegen ein Eindringen der Kunststoffschmelze zu schützen. Dazu wird üblicherweise ein Gehäuseteil verwendet, welches vor dem Umspritzen über die Leitung geschoben wird und an das die Formhälften angelegt werden. Dieses liegt so dicht um die Leitung, daß zwischen der Leitung und diesem Gehäuseteil keine Kunststoffschmelze durchtreten kann. Die Umspritzung der Leitung liegt auf der von der Steckerbuchse abgewandten Seite dieses Gehäuseteils.It is also known to seal the electrical lines with a To provide encapsulation. In the case of a plug part, this encapsulation from the electrical wire to the back of the connector pin, so that in this case substantially the entire housing of the male part can be formed by such extrusion coating. In a connector receiving part it is necessary, however, the socket when encapsulating against to protect penetration of the plastic melt. This is usually a Housing part used, which pushed over the line before overmolding and to which the mold halves are applied. This is so close to the Line, that between the line and this housing part no plastic melt can pass through. The encapsulation of the line is on the of the Plug socket facing away from this housing part.

Ein elektrischer Steckverbinder der eingangs genannten Art bzw. ein Verfahren der eingangs genannten Art ist aus der US 5 749 656 A bekannt. Dieser Steckverbinder weist als Steckelemente Kontaktstifte auf und bildet somit das Steckerteil der elektrischen Steckverbindung. Die elektrischen Leitungen sind über Crimpungen mit den Steckerstiften verbunden, wobei ein Gehäuseteil des Steckverbinders von einer die Crimpungen umgebenden Umspritzung gebildet wird. Hierbei werden die entsprechend ausgeformten Ränder der Formhälften an die Crimpungen angelegt.An electrical connector of the type mentioned or a method of the aforementioned type is known from US 5,749,656 A. This connector has contact pins as plug-in elements and thus forms the plug part the electrical connector. The electrical cables are crimped connected to the connector pins, wherein a housing part of the connector is formed by an encapsulation surrounding the crimps. in this connection The correspondingly shaped edges of the mold halves to the crimps created.

Aufgabe der Erfindung ist es, ein Steckeraufnahmeteil einer wasserdichten Steckverbindung bereitzustellen, welches zuverlässig gegen ein Eindringen von Wasser entlang der elektrischen Leitungen abgedichtet ist, dabei eine möglichst kleine Baugröße aufweist und auf einfache Weise herstellbar ist. Erfindungsgemäß gelingt dies durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 bzw. durch einen Steckverbinder mit den Merkmalen des Anspruchs 8.The object of the invention is a plug receiving part of a waterproof Provide connector that reliably against ingress of Water is sealed along the electrical lines, doing one as possible has small size and can be produced in a simple manner. According to the invention this is achieved by a method having the features of patent claim 1 or by a connector having the features of claim 8.

Steckerbuchsen mit Crimpanschlüssen sind bekannt, beispielsweise aus der erwähnten US 5 749 656 A, auch im Zusammenhang mit den bereits beschriebenen bekannten wasserdichten Steckverbindungen. Ein Crimpanschluß wird durch einen an der Steckerbuchse angeformten, in der Regel U-förmigen Blechteil gebildet, in welchen der anzuschließende elektrische Leiter eingelegt wird. In der Folge werden die Wangen des Blechteiles zusammengedrückt und dadurch wird der eingelegte elektrische Leiter festgelegt. Durch die Crimpverbindung wird eine mechanische Verbindung zwischen dem Leiter und der Buchse geschaffen und auch der elektrische Übergangskontakt. Im Zusammenhang mit Crimpkontakten werden üblicherweise aus einer Mehrzahl von Litzen gebildete Leiter verwendet, aber auch Hohlleiter eignen sich zum Crimpen. Steckerbuchsen mit Crimpanschlüssen können weiters auch mit elektrischen Leitern in Form von Folienleitem verbunden werden. Bei diesen sind auf einer isolierenden Trägerschicht festgelegte Leiterbahnen vorgesehen.Sockets with crimp connections are known, for example from the mentioned US 5,749,656 A, also in connection with those already described known waterproof connectors. A crimp connection is going through a formed on the socket, formed usually U-shaped sheet metal part, in which the electrical conductor to be connected is inserted. In the As a result, the cheeks of the sheet metal part are compressed and thereby becomes the inserted electrical conductor fixed. The crimp connection becomes a created mechanical connection between the conductor and the socket and also the electrical transition contact. In connection with crimp contacts usually ladders formed from a plurality of strands are used, but also waveguides are suitable for crimping. Sockets with crimp connections can also with electrical conductors in the form of Folienleitem get connected. These are fixed on an insulating support layer Conductors provided.

Ein Grundgedanke des erfindungsgemäßen Verfahrens bzw. eines erfindungsgemäßen Steckeraufnahmeteils besteht nun darin, daß sich der Crimpbereich so genau reproduzieren läßt, daß die mit entsprechenden Ausnehmungen versehenen Ränder der beiden Formhälften an diesen Crimpbereich angelegt werden können, um den Formhohlraum abzudichten. Es können dabei die Ränder der Formhälften in den Bereichen, in denen die Abdichtungen gegenüber den Crimpbereichen hergestellt werden sollen, nicht mit elastischen Dichtungen versehen werden, da diese keine ausreichende Verschleißfestigkeit gegenüber dem Spritzgußprozeß aufweisen würden. Die Abdichtung erfolgt somit direkt Metall auf Metall. Weiters darf durch diese Abdichtung auf dem jeweiligen Crimpbereich und dem anschließenden Spritzgußvorgang der Crimpbereich nicht ungünstig beeinflußt werden. Eine übliche Anforderung an die Crimpung, durch welche sichergestellt werden soll, daß durch das Crimpen eine ausreichend gute mechanische und elektrische Verbindung geschaffen worden ist, besteht darin, daß die Verbindung gasdicht ist. Diese für die Funktionssicherheit der Crimpung wesentliche Gasdichtheit darf durch die Abdichtung des Formhohlraumes im Crimpbereich beim Umspritzen-nicht verlorengehen. Auch der als Litzendraht oder auch als Leiterbahn eines Folienleiters ausgebildete elektrische Leiter darf nicht beschädigt werden. Da beim Spritzgußprozeß Drücke in der Höhe von 800 bis 1000 bar auftreten und eine entsprechende Zuhaltekraft auf die Formhätften ausgeübt werden muß, ist es durchaus überraschend, daß die Abdichtung des Formhohlraumes im Crimpbereich, wie es sich gezeigt hat, zu keiner Beschädigung der Crimpung führt. A basic idea of the method according to the invention or of a method according to the invention Plug receiving part is now that the crimp so reproduce exactly that provided with corresponding recesses Rims of the two mold halves are applied to this crimp can to seal the mold cavity. It can do the edges of the Mold halves in the areas where the seals against the crimping areas to be produced, not provided with elastic seals because these do not have sufficient wear resistance to the injection molding process would have. The seal is thus made directly from metal to metal. Furthermore, may by this seal on the respective crimping and the subsequent injection molding of the crimp not unfavorable to be influenced. A common crimping requirement, which ensures is to be that by crimping a sufficiently good mechanical and electrical connection has been created, is that the Compound is gas-tight. This essential for the reliability of crimping Gas-tightness is allowed by the sealing of the mold cavity in the crimping area not lost during encapsulation. Also as a stranded wire or too as a conductor of a film conductor trained electrical conductor may not be damaged become. Since the injection molding process pressures in the amount of 800 to 1000 occur bar and exerted a corresponding locking force on the Formhätften must be, it is quite surprising that the sealing of the mold cavity in Crimpbereich, as it has been shown, no damage to the Crimping leads.
