Elektrischer Stecker mit abgedichteten Metalleinlegeteilen Electrical plug with sealed metal inserts
Stand der TechnikState of the art
Die Erfindung geht aus von einem Stecker einer elektrischen Steckverbindung nach der Gattung des Patentanspruchs 1.The invention relates to a plug of an electrical connector according to the preamble of claim 1.
Das Umspritzen von Metalleinlegeteilen mit Kunststoff zur Herstellung von elektrischen Steckern ist weit verbreitet. Das Problem dabei ist die Dichtheit der Stecker an der Grenzfläche Metall zum Kunststoff, da die stoffschlüssige Verbindung zwischen Kunststoff und Metall auf Grund der sehr unterschiedlichen Wärmeausdehnungskoeffizienten des Stoffpaares sehr schlecht ist. Um dennoch die Dichtheit des Steckers zu erreichen, sind oft aufwändige Maßnahmen, wie z.B. Vorumspritzung oder zusätzliche Dichtelemente, notwendig. Vorteile der ErfindungThe encapsulation of metal inserts with plastic for the production of electrical plugs is widespread. The problem here is the tightness of the connector at the interface metal to plastic because the cohesive connection between plastic and metal is very poor due to the very different thermal expansion coefficient of the fabric pair. Nevertheless, to achieve the tightness of the plug, often expensive measures, such as pre-injection or additional sealing elements, necessary. Advantages of the invention
Der erfindungsgemäße Stecker mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, dass die kritische Verbindung zwischen den Metalleinlegeteilen und dem umspritzten Kunststoff mit einfachen Mitteln zuverlässig und wirkungsvoll abgedichtet ist. Erfindungsgemäß wird im Anschluss an den Standardprozess „Umspritzen von Metalleinlegeteilen mittels Kunststoff" durch die Dichtungs- oder Klebemasse die Dichtheit an der Kunststoff/Metall Grenzfläche erzielt. Vorzugsweise ist die Dichtungs- oder Klebemasse ein aushärtbares Gel, insbesondere ein Perfluorpolyether-Gel (z.B. Shin-Etsu SIFEL® 8070, Komponenten A und B der Fa. Shin-Etsu Chemical Co., Ltd., Tokio, Japan) oder ein Silikon-Gel (z.B. SEMICOSIL® 9242 der Fa. Wacker- Chemie, Burghausen), oder ein Klebstoff, insbesondere ein Silikon-Klebstoff (z.B. DOW CORNING® 866 Adhesive der Fa. Dow Corning GmbH, Wiesbaden). Vergelen ist ein bewährtes Standardverfahren, das sich durch geringe Kosten und einfache Handhabung auszeichnet. Es garantiert eine gute Anbindung sowohl an den Kunststoff als auch an das Metall des Einlegeteils, wobei diese Anbindung auch unter hohen Vibrationsbelastungen noch gegeben ist.The plug according to the invention with the characterizing features of claim 1 has the advantage that the critical connection between the metal inserts and the overmolded plastic is sealed reliably and effectively by simple means. According to the invention, following the standard process "encapsulation of metal insert parts by means of plastic", the sealant or adhesive material achieves the impermeability at the plastic / metal interface, Preferably, the sealant or adhesive composition is a hardenable gel, in particular a perfluoropolyether gel (for example: Etsu SIFEL 8070 ®, components a and B of the company. Shin-Etsu Chemical Co., Ltd., Tokyo, Japan) or a silicone gel (such as SEMICOSIL ® 9242 Fa. Wacker-Chemie, Burghausen), or an adhesive, in particular a silicone adhesive (eg DOW CORNING ® 866 adhesive of Messrs. Dow Corning GmbH, Wiesbaden). gelling is an established standard methods, which is characterized by low cost and easy handling. It ensures a good connection both to the plastic and to the metal of the insert, which connection is still given under high vibration loads.
Der erfindungsgemäße Stecker kann beispielsweise als elektrische Durchführung im Ölbereich eines Fahrzeugmotors, insbesondere als elektrische Durchführung aus dem ölfreien Innenraum eines Hochdrucksensors mit gegenüber Umwelteinflüssen sensibler Elektronik eingesetzt werden, um den Ölbereich abzudichten. Vorzugsweise ist der Stecker Teil eines den Raildruck erfassenden Drucksensors, dessen elektrische Leitungen durch den erfindungsgemäßen Stecker nach außen herausgeführt sind.The plug according to the invention can be used, for example, as an electrical feedthrough in the oil region of a vehicle engine, in particular as an electrical feedthrough from the oil-free interior of a high-pressure sensor with environmental electronics sensitive to seal the oil region.

Der ring- oder hülsenförmige Befestigungsflansch 4 ist ein Tiefziehteil, dessen kunststoffumspritztes Ende 4a nach innen umgebogen ist und dessen nach außen vorstehendes Flanschende 4b einen Innenraum 5 definiert. Die elektrischen Kontakte 3 treten an der dem Innenraum 5 abgewandten Gehäuseseite 2a in das Steckergehäuse 2 ein und an der dem Innenraum 5 zugewandten Gehäuseseite 2b aus dem Steckergehäuse 2 in den Innenraum 5 aus.The plug 1 shown in FIG. 1 of an electrical connector comprises a plug housing 2 made of plastic and plastic-encapsulated metal inserts, namely three electrical contacts (pins) 3 and a circumferential mounting flange 4. The annular or sleeve-shaped mounting flange 4 is a deep-drawn, whose plastic-molded end 4a is bent inwardly and the outwardly projecting flange 4b defines an inner space 5. The electrical contacts 3 enter at the side facing away from the interior 5 housing side 2a in the connector housing 2 and at the interior of the 5 facing housing side 2b from the connector housing 2 in the interior 5 from.
Der Stecker 1 ist im Spritzgussverfahren aus Kunststoff und mit den Kontakten 3 und dem Befestigungsflansch 4 als Metalleinlegeteilen hergestellt und anschließend abgekühlt. Allerdings ist die Verbindung zwischen dem Steckergehäuse 2 und denThe plug 1 is made by injection molding of plastic and with the contacts 3 and the mounting flange 4 as metal insert parts and then cooled. However, the connection between the connector housing 2 and the
Metalleinlegeteilen 3, 4 auf Grund der sehr unterschiedlichenMetal inserts 3, 4 due to the very different
Wärmeausdehnungskoeffizienten von Kunststoff und Metall nicht dicht, so dass z.B.Thermal expansion coefficient of plastic and metal not tight, so that e.g.
Wasser von außen entlang eines Spaltes zwischen dem Steckergehäuse 2 und den elektrischen Kontakten 3 bzw. dem Befestigungsflansch 4 in den Innenraum 5 gelangen kann.Water from the outside along a gap between the connector housing 2 and the electrical contacts 3 and the mounting flange 4 in the interior 5 can pass.
Um dennoch die Dichtheit des Steckers 1 zu erreichen, sind in Fig. 1 das Steckergehäuse 2 und der kunststoffumspritzte Befestigungsflansch 4 durch eine ausgehärtete Dichtungs- oder Klebemasse 6 gegeneinander abgedichtet, welche innenraumseitig auf der dem Innenraum 5 zugewandten Gehäuseseite 2b rings um den Befestigungsflansch 4, d.h. an der freiliegenden innenseitigen Kunststoff/Metall- Grenzfläche, aufgebracht ist. Obwohl nicht gezeigt, kann selbstverständlich die Dichtungs- oder Klebemasse 6 auch außerhalb des Innenraums 5 an der freiliegenden außenseitigen Kunststoff/Metall-Grenzfläche rings um den Befestigungsflansch 4 aufgebracht sein.In order nevertheless to achieve the tightness of the plug 1, in Fig. 1, the connector housing 2 and the plastic-coated mounting flange 4 by a cured sealant or adhesive 6 sealed against each other, which on the inside of the interior 5 facing housing side 2b around the mounting flange 4, that is applied to the exposed inside plastic / metal interface.
