Description
Diese Erfindung bezieht sich auf ein Verfahren zur Verbindung eines elektrischen Leiters mit einem Stift eines Steckverbinders sowie auf die durch die Anwendung dieses Verfahrens erzielte elektrische Verbindung.This invention relates to a method for connecting an electrical conductor to a pin of a connector and to the electrical connection achieved by applying this method.
Die meisten dieser Anschlüsse werden gegenwärtig hergestellt, indem eine mit dem Stift verbundene Hülse auf den zuvor abisolierten elektrischen Leiter aufgequetscht wird.Most of these connectors are currently made by crimping a sleeve connected to the pin onto the previously stripped electrical conductor.
Das Abisolieren der elektrischen Leiter erfolgt in der herkömmlichen Weise mit einer Handzange mit Messern mit verschiedenen Durchführungen, die jeweils einem bestimmten Leiterdurchmesser entsprechen. Die Bedienperson wählt den richtigen Durchmesser der Messer aus legt den Leiter in die Zange und betätigt diese, so daß die Messer bis auf die Leiterseele in die Isolierung eindringen. Durch eine Längsbewegung der Messer wird die Isolierung auf der Seele verschoben und entfernt. Der elektrische Leiter ist somit freigelegt und kann mit seinem Stift versehen werden.The insulation of the electrical conductors is stripped in the traditional way using hand pliers with blades with different openings, each of which corresponds to a specific conductor diameter. The operator selects the correct diameter of the blade, places the conductor in the pliers and operates them so that the blades penetrate the insulation down to the conductor core. The insulation on the core is displaced and removed by a longitudinal movement of the blades. The electrical conductor is thus exposed and can be fitted with its pin.
Da dieser Vorgang von Hand ausgeführt wird, können Beschädigungen der Leiterseele und ein mangelhafter Kontakt mit der Klemme oder ein unzulänglicher Halt der Quetschverbindung die Folge sein, die verursacht werden durch:Since this operation is carried out manually, damage to the conductor core and poor contact with the terminal or inadequate hold of the crimp connection can result, which can be caused by:
- eine falsche abisolierte Länge (die von der Bedienperson visuell eingeschätzt wird);- an incorrect stripped length (visually estimated by the operator);
- einen schadhaften Zustand des Abisolierwerkzeugs;- a damaged condition of the stripping tool;
- einen Fehler der Bedienperson hinsichtlich des Messerdurchmessers:- an error by the operator regarding the blade diameter:
ein kleinerer Durchmesser führt zu einer Zerstörung der Einzeldrähte unda smaller diameter leads to destruction of the individual wires and
ein größerer Durchmesser verursacht eine unvollkommene Abisolierung bei gleichzeitiger Quetschung auf der Isolierung;a larger diameter causes incomplete stripping and simultaneous crushing of the insulation;
- die Durchmessertoleranz der Leiterseele;- the diameter tolerance of the conductor core;
- das Umbiegen eines Drahts des Leiters bei dessen Einführung in die Hülse des Stifts.- bending of a conductor wire when inserting it into the sleeve of the pin.
Außerdem entstehen bei der eventuellen Verwendung mechanischer Mittel, wie Drehmesser und Laser, weitere Probleme, die mit deren Komplexität und ihrer schwierigen Anwendung verbunden sind.In addition, the possible use of mechanical means, such as rotary knives and lasers, gives rise to further problems related to their complexity and difficulty of application.
Diese Erfindung, deren Ziel es ist, diese Nachteile zu vermeiden, bezieht sich auf ein Verfahren zur Verbindung eines elektrischen Leiters mit dem Stift eines Steckverbinders, durch das jede Beschädigung des Leiters und/oder ein mangelhafter Kontakt mit dem Stift vermieden werden kann.This invention, the aim of which is to avoid these drawbacks, relates to a method of connecting an electrical conductor to the pin of a connector, by means of which any damage to the conductor and/or poor contact with the pin can be avoided.
Dazu ist das Verfahren zur Verbindung eines elektrischen Leiters mit dem Stift eines Steckverbinders, der eine Hülse hat, in die ein Ende des Leiters eingeführt wird, wobei das Verfahren darin besteht, daß die Hülse auf den Leiter aufgequetscht wird, erfindungsgemäß dadurch bemerkenswert, daß, bevor die Hülse des Stifts auf den Leiter aufgequetscht wird, ein elektrisch leitender Kleber in die Hülse eingebracht und das Ende des Leiters ohne Abisolierung in die Hülse eingeführt wird, so daß Leiter und Stift durch den Kleber elektrisch leitend miteinander verbunden werden.For this purpose, the method for connecting an electrical conductor to the pin of a connector which has a sleeve into which one end of the conductor is inserted, the method consisting in that the sleeve is crimped onto the conductor, is notable according to the invention in that, before the sleeve of the pin is crimped onto the conductor, an electrically conductive adhesive is introduced into the sleeve and the end of the conductor is inserted into the sleeve without stripping, so that the conductor and pin are electrically conductively connected to one another by the adhesive.
Somit kann zwischen Leiter und Stift eine zuverlässige elektrische Verbindung erzielt werden, ohne daß das Ende des Leiters mit allen damit verbundenen Nachteilen abisoliert und/oder Spezialwerkzeuge verwendet werden müssen, da die Endfläche der Metallseele des Leiters durch den Kleber elektrisch leitend mit dem Stift verbunden ist.This means that a reliable electrical connection can be achieved between the conductor and the pin without having to strip the end of the conductor with all the associated disadvantages and/or using special tools, since the end surface of the metal core of the conductor is electrically connected to the pin by the adhesive.
Vor allem kann auf den Boden der Hülse eine vorbestimmte Klebermenge aufgebracht werden.Above all, a predetermined amount of adhesive can be applied to the bottom of the sleeve.
Vorteilhafterweise wird das Ende des Leiters vor seiner Einführung in die Hülse insbesondere in einem Winkel, der wenigstens etwa gleich 45º ist, abgeschrägt.Advantageously, the end of the conductor is bevelled before it is inserted into the sleeve, in particular at an angle which is at least approximately equal to 45º.
Außerdem kann als Kleber ein metallgefüllter Klebstoff verwendet werden, wobei der Klebstoff vor allem eine thixotrope silbergefüllte Epoxydharzmasse sein kann.In addition, a metal-filled adhesive can be used as an adhesive, whereby the adhesive can primarily be a thixotropic silver-filled epoxy resin compound.
Die Figuren der beigefügten Zeichnung erleichtern das Verständnis dafür, wie die Erfindung verwirklicht werden kann.The figures of the accompanying drawings facilitate the understanding of how the invention can be implemented.
Figur 1 zeigt einen Steckverbinderstift mit einer Hülse zur Aufnahme des Endes eines elektrischen Leiters.Figure 1 shows a connector pin with a sleeve for receiving the end of an electrical conductor.
Figur 2 veranschaulicht die erfindungsgemäße Verbindung zwischen Stift und Leiter von Figur 1.Figure 2 illustrates the inventive connection between pin and conductor of Figure 1.
Der in Figur 1 gezeigte Stift 1 des Steckverbinders hat eine zylindrische Hülse 2, in die das Ende 3 eines elektrischen Leiters gesteckt wird, der aus einer metallischen Seele 4 mit einer umgebenden Isolierhülle 5 besteht.The pin 1 of the connector shown in Figure 1 has a cylindrical sleeve 2 into which the end 3 of an electrical conductor is inserted, which consists of a metallic core 4 with a surrounding insulating sheath 5.
Erfindungsgemäß wird ein elektrisch leitender aushärtbarer Kleber 6 zunächst in einer durch die Abmessungen der Hülse und folglich des Leiters vorbestimmten Menge auf den Boden der Hülse 2 gebracht. Das kann durch jedes geeignete Mittel geschehen, beispielsweise eine Mikrometerspritze mit Gradteilung. Dieser Kleber kann insbesondere eine thixotrope silbergefüllte Epoxydharzmasse sein, wie sie von der Firma EPOTECNY unter dem Handelsnamen EPOTEK 417 geliefert wird, deren technische Merkmale folgende sind:According to the invention, an electrically conductive hardenable adhesive 6 is first applied to the bottom of the sleeve 2 in a quantity determined by the dimensions of the sleeve and consequently of the conductor. This can be done by any suitable means, for example a graduated micrometer syringe. This adhesive can in particular be a thixotropic silver-filled epoxy resin mass such as that supplied by the company EPOTECNY under the trade name EPOTEK 417, the technical characteristics of which are as follows:
- Reziprokwert der spezifischen elektrischen Leitfähigkeit: 0,05-0,07 mΩ/cm.- Reciprocal of specific electrical conductivity: 0.05-0.07 mΩ/cm.
- Polymerisationszyklen: 1/2 Stunde bei 150 ºc 1 Stunde bei 100 ºC 2 Stunden bei 80 ºC- Polymerization cycles: 1/2 hour at 150 ºC 1 hour at 100 ºC 2 hours at 80 ºC
2-3 Tage bei Umgebungstemperatur.2-3 days at ambient temperature.
- Abbautemperatur nach der Polymerisation: 350 ºC.- Degradation temperature after polymerization: 350 ºC.
Vorteilhafterweise wird das Ende 3 des Leiters insbesondere in einen Winkel von wenigstens etwa 45º abgeschrägt, so daß sich die Kontaktfläche zwischen demselben und dem Kleber im Bereich der Endfläche der metallischen Seele 4 vergrößert.Advantageously, the end 3 of the conductor is bevelled in particular at an angle of at least about 45º, so that the contact area between the same and the adhesive in the region of the end surface of the metallic core 4 is increased.
Dann wird das Ende 3 des Leiters ohne Abisolierung in die Hülse 2 eingeführt, bis es mit dem Kleber 6 in Kontakt gelangt, der dieses, insbesondere die Endfläche der Metallseele 4, bedeckt, und verbindet so elektrisch leitend den Leiter mit dem Stift. Danach wird die Hülse 2 in herkömmlicher Weise wie in 7 (Figur 2) auf das Ende 3 aufgequetscht. Dabei wird diese Verbindung durch das Aushärten des Klebers verstärkt.The end 3 of the conductor is then inserted into the sleeve 2 without stripping it until it comes into contact with the adhesive 6 which covers it, in particular the end surface of the metal core 4, and thus electrically connects the conductor to the pin. The sleeve 2 is then crimped onto the end 3 in the conventional manner as in 7 (Figure 2). This connection is strengthened by the hardening of the adhesive.
Berechnungen zeigen, daß der Spannungsabfall im Bereich einer solchen Verbindung selbst unter den ungünstigsten Bedingungen vernachlässigbar und in jedem Fall durchaus kleiner als beispielsweise zwischen Steckern und Buchsen eines Steckverbinders ist.Calculations show that the voltage drop in the area of such a connection is negligible even under the most unfavorable conditions and in any case much smaller than, for example, between the plugs and sockets of a connector.
Außerdem ist festzustellen, daß, da durch das erfindungsgemäße Verfahren die elektrischen Leiter nicht abisoliert werden müssen, die Größe der an den Leitern anzubringenden Stifte nach dem Außendurchmesser der Leiter einschließlich Isolierung und nicht wie bei den früheren Verbindungsvorrichtungen nach dem Durchmesser der Leiter ohne Isolierung bestimmt werden muß.It should also be noted that, since the method according to the invention does not require stripping the electrical conductors, the size of the pins to be attached to the conductors must be determined according to the external diameter of the conductors including insulation and not, as in the case of previous connecting devices, according to the diameter of the conductors without insulation.
