Description
Spritzwerkzeug zum Herstellen von mehrpoligen Steckerbuchsen und damitInjection mold for the production of multi-pole sockets and thus
hergestellte Steckerbuchse Gegenstand der Erfindung ist ein Spritzwerkzeug zum Herstellen von mehrpoligen Steckerbuchsen mit einer Mehrzahl in einem Spritzkörper angeordneten gabelförmigen Buchsenelemente.Manufactured socket The invention relates to an injection molding tool for the production of multi-pole plug sockets with a plurality in an injection-molded body arranged fork-shaped socket elements.
Bisher stiel das Zusammenfassen von mehreren gabelförmigen Buchsenelementen in einem Spritzkörper durch Umspritzen auf Schwierigkeiten, weil das Spritzmaterial leicht in den zur Kontaktgabe vorgesehenen Raum in der Gabel eindringen konnte. So war man darauf angewiesen, Steckerbuchsen mit solchen Buchsenelementen aus den einzelnen Elementen zu montieren, was aufwendig und teuer war. Es war zwar schon aus der DD-PS 76 262 bekannt, in einer länglichen Kunststoffleiste eine Nut vorzusehen, in die ein leitender Belag eingebracht wird und diesen sodann durch Zahnschnitt in einzelne mechanisch zusammenhängende, elektrisch aber gegeneinander isolierte gabelförmige Buchsenelemente zu unterteilen. Die so entstehende Buchsenleiste war jedoch mechanisch empfindlich, die Buchsen schwer zu kontaktieren und stellte im Gegensatz zu einem Spritzkörper kein geschlossenes Ganzes dar.So far, the grouping of several fork-shaped socket elements has been handled in a molded body by overmolding on difficulties because the spray material could easily penetrate into the space provided for making contact in the fork. So you had to rely on sockets with such socket elements from the to assemble individual elements, which was time-consuming and expensive. It was already known from DD-PS 76 262 to provide a groove in an elongated plastic strip, into which a conductive coating is introduced and this then by tooth cut into individual mechanically connected, but electrically isolated from each other to subdivide fork-shaped socket elements. The resulting socket strip was but mechanically sensitive, the sockets difficult to contact and im In contrast to an injection-molded body, it does not represent a closed whole.
Der Erfindung liegt die Aufgabe zugrunde, einen Weg zu weisen, der es ermöglicht, Steckerbuchsen mit gabelförmigen Buchsenelementen in einen Spritzkörper einzuformen, bei dem die Buchsenelemente während des Spritzens nicht in der Gabelöffnung mit Kunststoff gefüllt werden und zu einem mechanisch widerstandsfähigen Gebilde zusammengefaßt werden.The invention has for its object to provide a way that it enables plug sockets with fork-shaped socket elements in an injection molded body to be molded in which the socket elements are not in the fork opening during spraying be filled with plastic and become a mechanically resistant structure be summarized.
Dies geschieht erfindungsgemäß mit Hilfe eines Spritzwerkzeugs, bei aem für jedes Buchsenelement eine Zunge vorhanden ist, auf die das Buchsenelement aufsteckbar ist und die die Gabelöffnungen des Buchsenelementes von vorne verschließt und bei dem beiderseits jede Zunge an diese wange angeformt sind, die die Gabelöffnungen von den Seiten her verschließen.According to the invention, this is done with the aid of an injection molding tool aem for each socket element there is a tongue on which the socket element can be attached and which closes the fork openings of the socket element from the front and in which each tongue is formed on both sides of this cheek, the fork openings close from the sides.
Die Verwendung des erfindungsgemäßen Spritzwerkzeuges erlaubt es, eine Mehrzahl von gabelförmigen Buchsenelementen in einem Arbeitsgang zu einer kompakten Steckerbuchse zu verbinden, ohne ihre elektrische Brauchbarkeit zu beeinträchtigen.The use of the injection molding tool according to the invention allows a plurality of fork-shaped socket elements in one operation to a compact one To connect socket without affecting their electrical usability.
Um das Kontaktierungsvermögen der gabelförmigen Buchsenelemente nicht zu beeinträchtigen, wird die Dicke der Zungen so bemessen, daß diese die Buchsenelemente nicht auftreiben.Not about the contacting capacity of the fork-shaped socket elements to affect, the thickness of the tongues is so dimensioned that these the socket elements do not find it.
In Weiterbildung der Erfindung überragen die Wangen die Buchsenelemente nach oben und unten und reichen mindestens um das gleiche Maß über den Boden der Gabelöffnung hinaus. Dies führt zu geringeren Steckkräften und weiter verbessert es die Abdichtung der Gabelöffnung gegen die Spritzmasse.In a further development of the invention, the cheeks protrude beyond the socket elements up and down and extend at least the same amount above the bottom of the Fork opening out. This leads to lower insertion forces and is further improved it seals the fork opening against the injection molding compound.
Weiterer Gegenstand der Erfindung ist eine Steckerbuchse, die mit einem wie vorstehend beschriebenen Werkzeug hergestellt ist. Erfindungsgemäß sind die Buchsenelemente vor dem Verspritzen mit anderen elektrischen Schaltelementen elektrisch leitend verbunden. Dies hat den Vorteil, daß durch das Spritzen höhere Abdichtungen gegen Wassereintritt hergestellt sind. Die Buchsenelemente können dabei mit Schaltelementen,wie Bandleitern, flexiblen gedruckten Schaltungen, normalen isolierten Adern oder auch Lötösen oder Klemmen, verbunden sein. Bei der herkömmlichen Technik, bei der die Buchsenelemente montiert werden mußten, waren dazu besondere Dichtmittel, z. B. Lötmuffen, erforderlich.Another object of the invention is a socket with a tool as described above is made. Are according to the invention the socket elements before spraying with other electrical switching elements electrically connected. This has the advantage that, due to the spraying, higher Seals against water ingress are made. The socket elements can thereby with circuit elements such as ribbon conductors, flexible printed circuits, normal isolated wires or soldering lugs or terminals. With the conventional The technology in which the socket elements had to be assembled were special Sealant, e.g. B. solder sleeves, required.
Die Figuren zeigen in zum Teil schematischer Darstellung ein Ausführungsbeispiel eines Werkzeugs und einer damit hergestellten Steckerbuchse gemäß der Lehre der Erfindung.The figures show an exemplary embodiment in a partially schematic representation a tool and a socket made therewith according to the teaching of Invention.
In Fig. 1 und 2 ist der hier nur teilweise dargestellte Werkzeugkörper mit 1 1 bezeichnet. Er trägt die Zungen 2, die an die Wangen 3 angeformt sind.In Fig. 1 and 2, the tool body is only partially shown here denoted by 1 1. He wears the tongues 2, which are molded onto the cheeks 3.
Wie aus Fig. 2 ersichtlich, wurden auf die Zungen 2 gabelförmige Buchsenelemente 4 aufgesteckt. Das Werkzeug ist so dimensioniert, daß die Zan e 2 die Gabelöffnung des Buchsenelementes 4 von vorne abschließt ohne ds Element aufzutreiben und daß die Wangen 3 die Gabelöffnung von den Setzten her verschließen, so daß weder von vorne noch von der Seite her Spritnasse in die Gabelöffnung eindringen kann.As can be seen from Fig. 2, 2 fork-shaped socket elements were on the tongues 4 attached. The tool is dimensioned so that the Zan e 2 the fork opening of the socket element 4 closes from the front without driving up the element and that the cheeks 3 close the fork opening from the set, so that neither of At the front, spray moisture can penetrate into the fork opening from the side.
Fig. 3 und 4 zeigen eine Steckerbuchse, die mit Hilfe des erfindungsgemäßen Werkzeuges hergestellt ist, wobei Fig. 3 einen Schnitt mittig durch den Gegenstand der Fig. 4 darstellt. Fig. 3 zeigt das gabelförmige Buchsenelement 4, an das vor dem Spritzen eine isolierte Ader 6 angeschlossen worden ist. Das Element 4 ist von einem Steckerkörper 7 umgeben, der die Anschlußstelle zu der Ader 6 abdichtend umgibt und nach vorne in eine profilierte Öffnung 8 ausläuft. Mit Hilfe der im Ansatz 9 vorgesehenen Bohrung 10 kann der Stecker an seinen Arbeitsort festgelegt werden. In Fig. 4 ist zu erkennen, daß die Steckerbuchsen fünf Buchsenelemente enthält, von denen jeweils die Enden 11 der Gabel zu erkennen sind. Neben den Buchsenelementen erscheint in Folge der Überhöhung der Wangen des Spritzwerkzeuges je eine Ausnehmung 5.Fig. 3 and 4 show a socket with the help of the invention Tool is made, Fig. 3 is a section through the center of the object 4 represents. Fig. 3 shows the fork-shaped socket element 4, to the front an insulated wire 6 has been connected to the spraying. Element 4 is from a plug body 7 which surrounds the connection point to the wire 6 in a sealing manner and runs out towards the front into a profiled opening 8. With the help of the approach 9 provided hole 10, the plug can be set at its place of work. In Fig. 4 it can be seen that the sockets contains five socket elements, each of which the ends 11 of the fork can be seen. In addition to the socket elements As a result of the elevation of the cheeks of the injection molding tool, a recess appears 5.
Die mit dem erfindungsgemäßen Spritzwerkzeug hergestellten Steckerbuchsen eignen sich besonders zur Verwendung an flexiblen gedruckten Schaltungen.The plug sockets produced with the injection molding tool according to the invention are particularly suitable for use on flexible printed circuits.
