Elektrisches Kontaktelement Beschreibung Electrical contact element Description
Die Erfindung betrifft ein elektrisches Kontaktelement nach dem Oberbegriff des unabhängigen Anspruchs 1 . The invention relates to an electrical contact element according to the preamble of the independent claim 1.
Derartige Kontaktelemente werden benötigt, um eine elektrisch leitende Verbindung zwischen zwei elektrischen Leitern herzustellen. Üblicher Weise sind ein oder mehrere Kontaktelemente zusammengefasst in einem Isolierkörper aufgenommen und bilden so einen Steckverbinder. Such contact elements are needed to produce an electrically conductive connection between two electrical conductors. Usually, one or more contact elements are combined in an insulating body and thus form a connector.
Die elektrischen Kontaktelemente haben dabei die Aufgabe, einerseits eine Verbindung zu einem Kontaktelement eines Gegensteckverbinders herzustellen. Dafür ist eine Steckseiten derartiger elektrischer Kontaktelemente als Stift- oder Buchsenkontakt ausgebildet. Jeweils ein Buchsenkontakt kann mit einem Stiftkontakt zusammengesteckt und so eine elektrische Verbindung hergestellt werden. The electrical contact elements have the task, on the one hand to establish a connection to a contact element of a mating connector. For a plug-in sides of such electrical contact elements is designed as a pin or socket contact. In each case a socket contact can be plugged together with a pin contact and so an electrical connection can be made.
Andererseits muss ein derartiges elektrisches Kontaktelement eine Verbindung zu einem elektrischen Leiter herstellen. Hierfür weist das elektrische Kontaktelement eine Anschlussseite auf. Für die Ausgestaltung der Anschlussseite gibt es im Stand der Technik eine Vielzahl von Lösungen. On the other hand, such an electrical contact element must establish a connection to an electrical conductor. For this purpose, the electrical contact element has a connection side. For the design of the connection side, there are a variety of solutions in the prior art.
Stand der Technik State of the art
Die DE 1 164 532 A zeigt ein umkehrbares Kontaktelement für elektrische Steckvorrichtungen mit einer Steckseite und einer Anschlussseite. Die Anschlussseite ist dabei als einfache Lötfahne ausgebildet. An der als Lasche ausgebildeten Lötfahne kann ein zu kontaktierender elektrischer Leiter angelötet werden. Aus der DE 1 135 072 B ist ein Flach-Kontaktelement für elektrische Steckvorrichtungen bekannt, dass zwecks Herstellung der Steckverbindung mit seinem Gegenkontaktelement unter einem Winkel von 90° zusammengeführt wird. Das als Blechbiegeteil ausgeführte Kontaktelement weißt auf seiner Anschlussseite mehrere Blechlaschen auf, die zum Verquetschen eines anzuschließenden elektrischen Leiters vorgesehen sind. DE 1 164 532 A shows a reversible contact element for electrical plug-in devices with a plug side and a connection side. The connection side is designed as a simple soldering lug. At the formed as a tab Lötfahne an electrical conductor to be contacted can be soldered. From DE 1 135 072 B a flat contact element for electrical plug-in devices is known that is brought together for the purpose of producing the plug connection with its mating contact element at an angle of 90 °. The designed as a bent metal part contact element know on its connection side on several metal tabs, which are provided for squeezing a connected electrical conductor.
Die DE 1 992 567 U1 offenbart ein mit Steckstift oder Steckbuchse versehenes Kontaktelement aus Vollmaterial welches zur, leicht wiederlösbaren, einrastend verriegelten Befestigung in Kammern einstückig hergestellter Isoliergehäuse bestimmt ist. Dabei weist das Kontaktelement an seiner Anschlussseite ein Leitungsanschlussteil auf, welches für eine Crimp-Verbindung mit einer angeschlossenen Leitung vorgesehen ist. DE 1 992 567 U1 discloses a contact element made of solid material which is provided with a plug pin or socket and which is intended to be fastened in chambers in an integrally produced insulating housing in an easily releasable latching manner. In this case, the contact element on its connection side on a line connection part, which is provided for a crimp connection with a connected line.
Derartige Crimp-Anschlüsse haben sich als besonders vorteilhaft herausgestellt. Die Anschlussseite des Kontaktelements ist besonders einfach und kostengünstig herzustellen und gleichzeitig kann eine Kontak- tierung mit einem entsprechenden Crimp-Werkzeug überall einfach und schnell hergestellt werden. Dies bietet, vor allem gegenüber einer gelöteten Verbindung wie in der DE 1 164 532 A eingangs beschrieben, einen besonderen Vorteil in der Flexibilität hinsichtlich der Montage und des Anschlusses eines Leiters an den Kontaktelementen. Such crimp connections have proven to be particularly advantageous. The connection side of the contact element is particularly simple and inexpensive to manufacture and at the same time contact with a corresponding crimping tool anywhere can be easily and quickly produced. This offers, especially with respect to a soldered connection as described in DE 1 164 532 A at the outset, a particular advantage in the flexibility with respect to the mounting and the connection of a conductor to the contact elements.
Nachteilig wirkt sich bei aus dem Stand der Technik bekannten Alternativlösungen zu Lötanschlüssen aus, dass diese nicht für Aluminiumleiter geeignet sind. Bekanntlich oxidiert Aluminium an der Luft sofort. Die sich bei der Oxidation bildende Oxidschicht auf dem Aluminium hemmt die elektrische Leitfähigkeit. Die Kontaktierung eines elektrischen Leiters, der aus Aluminium besteht, ist dadurch mit den aus dem Stand der Technik bekannten Anschlussmöglichkeiten nicht ausreichend. Durch eine Crimp-Verbindung wird der elektrische Leiter gequetscht und die Oxidschicht zwischen dem elektrischen Leiter und der Anschlussseite des elektrischen Kontakts eingepresst. A disadvantage of known from the prior art alternative solutions to Lötanschlüssen that they are not suitable for aluminum conductors. Aluminum is known to oxidize in the air immediately. The oxide layer forming on the aluminum during the oxidation inhibits the electrical conductivity. The contacting of an electrical conductor, which consists of aluminum, is therefore not sufficient with the known from the prior art connection options. By crimping the electrical conductor is crushed and pressed the oxide layer between the electrical conductor and the terminal side of the electrical contact.
Vor allem bei der Kontaktierung von Aluminium-Leitern, die aus eine Vielzahl von feinen Litzen bestehen, kann eine gute elektrische Kontaktierung auf Grund der vielen Oxidschichten auf den einzelnen Litzen nicht mehr sichergestellt werden. Especially in the contacting of aluminum conductors, which consist of a variety of fine strands, a good electrical contact due to the many oxide layers on the individual strands can no longer be ensured.
Aufgabenstellung task
Die Aufgabe der Erfindung besteht darin, ein elektrisches Kontaktelement so auszubilden, dass eine sichere und elektrisch leitfähige Kontaktierung von Aluminium-Leitern gewährleistet werden kann. The object of the invention is to design an electrical contact element such that a secure and electrically conductive contacting of aluminum conductors can be ensured.
Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst. The object is solved by the characterizing features of independent claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous embodiments of the invention are specified in the subclaims.
Die Erfindung betrifft ein elektrisches Kontaktelement, welches zur Kontaktierung und zum elektrischen Anschluss eines elektrischen Leiters vorgesehen ist. Zweckmäßig verfügt das elektrische Kontaktelement über eine Steckseite und eine Anschlussseite. The invention relates to an electrical contact element which is provided for contacting and electrical connection of an electrical conductor. Suitably, the electrical contact element has a plug side and a connection side.
Die Steckseite des elektrischen Kontaktelements ist - wie im Stand der Technik bereits vielfach bekannt - als Stiftkontakt oder Buchsenkontakt ausgebildet. Durch Zusammenführen eines elektrischen Kontaktelements mit Stiftkontakt und eines weiteren mit Buchsenkontakt kann so eine elektrisch leitende Steckverbindung hergestellt werden. The mating side of the electrical contact element is - as already well known in the art - designed as a pin contact or socket contact. By merging an electrical contact element with pin contact and another with female contact so an electrically conductive connector can be made.
Die Anschlussseite des elektrischen Kontaktelements ist als hülsenförmig geformt und bildet eine Anschlusshülse. In diese Anschlusshülse kann ein elektrischer Leiter eingeführt werden und mittels eines sogenannten Crimp-Werkzeugs in der Anschlusshülse verquetscht werden. Diese Art von Crimp-Anschluss ist aus dem Stand der Technik vielfach bekannt. The connection side of the electrical contact element is shaped as a sleeve-shaped and forms a connection sleeve. In this connection sleeve, an electrical conductor can be inserted and be squeezed by means of a so-called crimping tool in the connection sleeve. This type of crimping connection is well known in the art.
Die vorliegende Erfindung ist speziell für elektrische Leiter vorgesehen, die aus Aluminium bestehen und eine Vielzahl von Litzen aufweisen. Dafür verfügt des elektrische Kontaktelement über ein Spleißelement welches in der Anschlusshülse des elektrischen Kontaktelements vorgesehen ist. Das Spleißelement besteht aus zumindest zwei Spleißsegmenten, die auf der Innenseite der Anschlusshülse, über deren Umfang verteilt angeordnet sind. The present invention is specifically intended for electrical conductors made of aluminum and having a plurality of strands. For this, the electrical contact element has a splicing element which is provided in the connection sleeve of the electrical contact element. The splice element consists of at least two splice segments, which are arranged distributed on the inside of the connection sleeve, over the circumference thereof.
Die Spleißsegmente sind vorzugsweise radial nach innen gerichtete, sich verjüngende Elemente. Eine Art Keilform ist besonders vorteilhaft. Zweck der Spleißsegmente ist es, beim Quetschvorgang zwischen die einzelnen Litzen eines eingeführten, elektrischen Leiters zu dringen. The splice segments are preferably radially inwardly directed, tapered elements. A type of wedge shape is particularly advantageous. The purpose of the splice segments is to penetrate between the individual strands of an inserted electrical conductor during the crimping process.
Beim Eindringen zwischen die Einzellitzen eines Aluminium-Leiters brechen die Spleißsegmente die Oxidschicht, welche sich auf jeder einzelnen Litze des Leiters gebildet hat, auf. So wird eine gute elektrische Kontaktie- rung der einzelnen Litzen sichergestellt. When penetrating between the individual strands of an aluminum conductor, the splice segments break the oxide layer which has formed on each individual strand of the conductor. This ensures good electrical contacting of the individual strands.
In einer besonders vorteilhaften Ausführungsform sind die Oberflächen der Spleißsegmente mit einer rauen Oberfläche versehen. Diese raue Oberfläche dient besonders gut einem Aufbrechen der Oxidschicht auf den Litzen. Das Spleißelement kann je nach Ausführung und Durchmesser des elektrischen Kontaktelements eine unterschiedliche Anzahl von In a particularly advantageous embodiment, the surfaces of the splice segments are provided with a rough surface. This rough surface is particularly good for breaking up the oxide layer on the strands. Depending on the design and diameter of the electrical contact element, the splicing element can have a different number of
Spleißsegmenten aufweisen. So ist zum Beispiel ein Spleißelement mit sechs Spleißsegmenten besonders vorteilhaft. Have splice segments. For example, a splice element with six splice segments is particularly advantageous.
In einer Aufführungsvariante sind die Spleißsegmente direkt mit der Anschlusshülse einteilig hergestellt. Diese können beispielsweise als an der Innenfläche angeformte Keile in der Anschlusshülse angeordnet sein. Beim Quetschen oder Crimpen eines elektrischen Leiters in der Anschlusshülse, werden die Spleißsegmente zwischen die einzelnen Litzen des Leiters gepresst. In a performance variant, the splice segments are made in one piece directly with the connection sleeve. These can be arranged, for example, as formed on the inner surface wedges in the connection sleeve. When crimping or crimping an electrical conductor in the ferrule, the splice segments are pressed between the individual strands of the conductor.
Eine weitere, vorteilhafte Ausführungsform sieht vor, das Spleißelement als separates Bauteil auszubilden. Dabei verfügt das Spleißelement für eine Basis, an welcher die einzelnen Spleißsegmente angeformt sind. Vorzugsweise ist dabei das Spleißelement so in der Anschlusshülse zu positionieren, dass die Basis voran in die Anschlusshülse geschoben wird und die Spleißsegmente vom Inneren in Richtung des offenen Endes der Anschlusshülse ragen, aber jedoch noch in der Anschlusshülse aufgenommen sind. A further advantageous embodiment provides to form the splice element as a separate component. In this case, the splice element has a base on which the individual splice segments are formed. Preferably, the splice element is to be positioned in the connection sleeve such that the base is pushed forward into the connection sleeve and the splice segments protrude from the interior in the direction of the open end of the connection sleeve, but are still accommodated in the connection sleeve.
Bei der Montage eines solchen elektrischen Kontaktelements mit separatem Spleißelement ist vorgesehen, zuerst das Spleißelement über die freigelegten Litzen des elektrischen Leiters zu schieben. Dabei fächert das Spleißelement die einzelnen Litzen so auf, dass diese sich zwischen die Spließsegmente verteilen. When assembling such an electrical contact element with a separate splice element, it is provided to first push the splice element over the exposed strands of the electrical conductor. The splicing element fans out the individual strands so that they spread between the splitting segments.
Anschließend kann das Ende des elektrischen Leiters, zusammen mit dem aufgesteckten Spleißelement in die Anschlusshülse geschoben werden. Durch Quetschen der Anschlusshülse mit einer Zange oder einem speziellen Crimp-Werkzeug werden anschließend die Spleißsegmente weiter zwischen die Litzen getrieben. Dadurch wird die Oxidschicht an der Oberfläche der Litzen aufgebrochen und eine elektrische Kontaktierung einer Vielzahl von Litzen sichergestellt. Subsequently, the end of the electrical conductor can be pushed together with the plugged splice in the connection sleeve. By squeezing the connection sleeve with a pair of pliers or a special crimping tool, the splice segments then continue driven between the strands. As a result, the oxide layer is broken on the surface of the strands and ensures electrical contacting of a plurality of strands.
In einer bevorzugten Ausführungsform des elektrischen Kontaktelements mit separatem Spleißelement ist ein Befestigungsmittel vorgesehen, welches dazu dient, das Spleißelement in der Anschlusshülse zu fixieren. Dazu ist eine Verbindungsbohrung zwischen Steckseite und Anschlussseite im elektrischen Kontaktelement eingebracht, durch welche das Befestigungsmittel auf das Spleißelement einwirken kann. In a preferred embodiment of the electrical contact element with a separate splice element, a fastening means is provided which serves to fix the splice element in the connection sleeve. For this purpose, a connecting bore between the plug side and the connection side is introduced in the electrical contact element, through which the fastening means can act on the splicing element.
Zweckhaft ist es hierbei, eine Schraube als Befestigungsmittel zu verwenden. Diese kann aus Richtung der Steckseite durch die Verbindungsbohrung geschoben werden und in ein entsprechendes Gewinde in der Basis des Spleißelements eingreifen. Ein Herausziehen des Spleißelements aus der Anschlusshülse wird so verhindert. It is useful here to use a screw as a fastener. This can be pushed from the direction of the plug side through the connecting hole and engage in a corresponding thread in the base of the splice element. Pulling out the splice element from the connection sleeve is thus prevented.
In einer weiteren Ausführungsform ist vorgesehen, auf der Außenfläche der Anschlusshülse Nuten einzubringen, welche um die Anschlusshülse verlaufen. Diese sind zur Anzeige für den Nutzer vorgesehen, um anzuzeigen, wo mit einem Quetsch- oder Crimpwerkzeug angesetzt werden muss. Auf Grund der Spleißsegmente ist eine regelmäße Anordnung der Crimp-Stellen wichtig, um eine möglichst gute elektrische Kontaktierung zu gewährleisten. In a further embodiment, it is provided to introduce grooves on the outer surface of the connecting sleeve, which run around the connecting sleeve. These are for display to the user to indicate where to use a crimp or crimp tool. Due to the splice segments a regular arrangement of the crimping points is important to ensure the best possible electrical contact.
Eine zusätzliche, vorteilhafte Ausführungsform sieht vor, auf der Außenfläche der Anschlusshülse zumindest eine Markierung vorzusehen. Diese Markierung dient zur Ausrichtung eines Crimpwerkzeugs. Crimpwerkzeu- ge bestehen meist aus mehreren Backen, die den zu crimpenden Gegenstand einwirken. Da nicht über den gesamten Umfang gleichmäßig Kraft eingebracht werden kann, wird so abschnittsweise Kraft eingeleitet. Daraus resultiert, dass entweder Dellen in das Kontaktelement gedrückt werden, oder aus z.B. einer runden Form ein Vieleck gepresst wird. So wird an mehreren Punkten eine Kraft von der Anschlusshülse auf den innenliegenden Leiter eingeleitet und dieser so fixiert. An additional, advantageous embodiment provides for providing at least one marking on the outer surface of the connecting sleeve. This marking is used to align a crimping tool. Crimping tools usually consist of several jaws which act on the object to be crimped. Since it is not possible to apply uniform force over the entire circumference, in some sections force is introduced. As a result, either dents are pressed into the contact element, or from a round shape, for example, a polygon is pressed. Thus, a force is introduced from the connecting sleeve to the inner conductor at several points and this fixed so.
Um diese, nicht über den gesamten Umfang gleichmäßig eingeleitete Kraft möglichst auf die Spleißsegmente zu zentrieren, ist die Markierung vorgesehen. Diese ist so angebracht, dass mit entsprechendem Anlegen des Crimpwerkzeugs, die maximale Kraft auf die Spleißsegmente eingeleitet wird. In order to center this force, which is not uniformly introduced over the entire circumference, as far as possible on the splice segments, the marking is provided. This is arranged so that with appropriate application of the crimping tool, the maximum force is introduced to the splice segments.
Damit die in der Ausführungsform vorgesehene Markierung auch an der korrekten Stelle auf der Anschlusshülse vorgesehen ist, muss das Spleißelement verdrehsicher in der Anschlusshülse einfügbar sein. Dies kann sowohl über eine zusätzliche Bohrung in der Anschlusshülse und einen Stift oder eine Schraube realisiert werden, welch durch die Bohrung in eine Ausnehmung in die Basis des Spleißelements eingreift. In order for the marking provided in the embodiment to also be provided at the correct location on the connecting sleeve, the splicing element must be insertable against rotation in the connecting sleeve. This can be realized both via an additional hole in the connection sleeve and a pin or a screw, which engages through the hole in a recess in the base of the splice element.
Auch denkbar wäre eine Führungsnut in Zusammenwirkung mit einer Führungsfeder, welche in Spleißelement und Innenfläche der Anschlusshülse vorgesehen sind. Dabei kann sowohl die Nut im Spleißelement und die Feder an der Anschlusshülse, als auch eine umgekehrte Lösung vorgesehen sein. Also conceivable would be a guide groove in cooperation with a guide spring, which are provided in splice element and inner surface of the connection sleeve. In this case, both the groove in the splice element and the spring on the connection sleeve, as well as a reverse solution may be provided.
Des Weiteren ist es vorteilhaft, die gesamte Innenfläche der Anschlusshülse mit einer rauen bis scharfkantigen Oberfläche zu versehen. So können beim Quetschen oder Crimpen der Anschlusshülse auch die Litzen eines Leiters aufgeraut und die Oxidschicht durchbrochen werden, die nicht in direktem Kontakt mit den Spleißsegmenten stehen. Furthermore, it is advantageous to provide the entire inner surface of the connection sleeve with a rough to sharp-edged surface. Thus, when squeezing or crimping the ferrule, the strands of a conductor can be roughened and the oxide layer can be broken, which are not in direct contact with the splice segments.
In einer speziellen Ausführungsform des erfindungsgemäßen elektrischen Kontaktelements, weisen die Spleißsegmente des Spleißele- ments eine besonders vorteilhafte Form auf. Dabei sind die Spleißsegmente im Bereich der Öffnung der Anschlusshülse breiter ausgeprägt, als in dem, der Steckseite zugewandten Bereich. In a specific embodiment of the electrical contact element according to the invention, the splice segments of the splice element have ment a particularly advantageous form. The splice segments are wider in the region of the opening of the connecting sleeve than in the area facing the plug side.
Diese Form der Spleißsegmente bezweckt, dass im Bereich der An- schlusshülsenöffnung die einzelnen Litzen eines elektrischen Leiters stärker verquetscht werden als im steckseitig zugewandten Bereich. The purpose of this form of splice segment is that the individual strands of an electrical conductor are more strongly squeezed in the area of the connection sleeve opening than in the area facing the plug side.
Wirkt eine Kraft auf einen befestigten elektrischen Leiter, der diesen aus der Anschlusshülse zieht, bilden die Litzen des elektrischen Leiters im steckseitigen Bereich ein Pfropfen, der nur erschwert durch den engeren, hinteren Bereich gezogen werden kann. If a force acts on a fixed electrical conductor pulling it out of the connection sleeve, the strands of the electrical conductor form a plug in the area on the plug side, which can only be pulled through the narrower, rear area with difficulty.
Die Erfindung betrifft ein elektrisches Kontaktelement zur Kontaktierung eines elektrischen Litzenleiters, wobei das elektrische Kontaktelement über eine Anschlussseite und eine Steckseite verfügt. Zur besseren elektrischen Kontaktierung eines elektrischen Litzenleiters ist in einer, die Anschlussseite bildende Anschlusshülse ein Spleißelement vorgesehen. The invention relates to an electrical contact element for contacting an electrical stranded conductor, wherein the electrical contact element has a connection side and a plug side. For better electrical contacting of an electrical stranded conductor, a splicing element is provided in a connection sleeve forming the connection side.
Das Spleißelement ist dafür vorgesehen, die einzelnen Litzen des Leiters aufzufächern, eine möglichst große Oberfläche der einzelnen Litzen zu kontaktieren und bei einem Quetsch- oder Crimpvorgang die Oberfläche der Litzen zu verletzten. Die Erfindung stellt eine sichere, elektrische Kontaktierung von Litzenleitern vor, bei welcher eine kontaktierungsungeeig- nete, schlecht leitfähige Oberfläche der einzelnen Litzen durchdrungen wird. The splice element is designed to fan out the individual strands of the conductor, to contact the largest possible surface of the individual strands and to injure the surface of the strands in a crimping or crimping operation. The invention provides a safe, electrical contacting of stranded conductors, in which a kontaktierungsungeeig-- designated, poorly conductive surface of the individual strands is penetrated.

Leiter in einer Schnittdarstellung. Ladder in a sectional view.
Die Figur 1 zeigt ein elektrisches Kontaktelement 1 in einem Längsschnitt entlang der Längsachse A. Dabei ist im rechten Bereich eine Steckseite 2 des elektrischen Kontaktelements 1 dargestellt. Im linken Bereich ist eine hülsenförmige Anschlussseite 3 dargestellt. Die hülsenförmige Anschlussseite 3 wird von einer Anschlusshülse 4 gebildet. 1 shows an electrical contact element 1 in a longitudinal section along the longitudinal axis A. Here, a plug-in side 2 of the electrical contact element 1 is shown in the right area. In the left area a sleeve-shaped connection side 3 is shown. The sleeve-shaped connection side 3 is formed by a connection sleeve 4.
Gemäß der vorliegenden Erfindung ist innerhalb der Anschlusshülse 4 ein Spleißelement 10 vorgesehen. Das Spleißelement 10 weist im Wesentlichen eine Basis 12, sowie mehrere Spleißsegmente 1 1 auf. Die Basis 12 ist am hintersten Bereich in der Anschlusshülse 4 vorgesehen. According to the present invention, a splice element 10 is provided inside the connection sleeve 4. The splicing element 10 essentially has a base 12 and a plurality of splice segments 1 1. The base 12 is provided at the rearmost area in the connection sleeve 4.
Um ein Herausfallen des Spleißelements 10 zu verhindern, ist dieses mittels eines Befestigungsmittels 13 - hier eine Schraube - im elektrischen Kontaktelement fixiert. In der speziellen dargestellten Ausführungsform ist die Schraube von der Steckseite 2 durch eine Bohrung 5 im elektrischen Kontaktelement 4 geführt und in die Basis 12 des Spleißelements 10 geschraubt. To prevent falling out of the splice element 10, this is fixed by means of a fastening means 13 - here a screw - in the electrical contact element. In the specific embodiment shown, the screw is guided from the plug side 2 through a bore 5 in the electrical contact element 4 and screwed into the base 12 of the splice element 10.
Die Spleißsegmente 1 1 des Spleißelements 10 sind von der Basis 12 weg gerichtet in der Anschlusshülse 4 verteilt. Vorteilhaft erstrecken sich die Spleißsegmente 1 1 über fast die gesamte Länge der Anschlusshülse 4. In der hier dargestellten Ausführung - sowie allen weiteren Figuren - verfügt das Spleißelement 10 über sechs Spleißsegmente 1 1 . Im mittleren Bereich des Spleißelements 10, wo die Spleißsegmente 1 1 an der Basis 12 angebracht sind, ist zu erkennen, dass die Materialstärke hier geringer ist, als die Spleißsegmente 1 1 selber. Dies dient vorteilhaft einer hohen Flexibilität der Spleißsegmente 1 1 zur Basis 12. The splice segments 1 1 of the splice element 10 are directed away from the base 12 in the connection sleeve 4. Advantageously, the splice segments 1 1 extend over almost the entire length of the connecting sleeve 4. In the embodiment shown here - as well as all other figures - the splicing element 10 has six splice segments 1 1. In the central region of the splice element 10, where the splice segments 1 1 are attached to the base 12, it can be seen that the material thickness is lower here than the splice segments 1 1 itself. This advantageously serves a high flexibility of the splice segments 1 1 to the base 12.
In der Figur 2 ist das elektrische Kontaktelement 1 wie in Figur 1 noch einmal dargestellt. Jedoch ohne das Spleißelement 10. Hier besser zu erkennen ist die Bohrung 5, welche die Steckseite 2 des elektrischen Kontaktelements 1 mit der Anschlussseite 3 verbindet. In FIG. 2, the electrical contact element 1 is shown once again as in FIG. However, without the splice element 10. Here, the bore 5, which connects the plug side 2 of the electrical contact element 1 to the connection side 3, can be seen better.
Im Inneren der Anschlusshülse 4 ist in der Figur 2 eine gewindeartige Kontur an der Innenseite 18 zu erkennen. Diese vorteilhaft scharfkantige Kontur dient ebenfalls dem Aufbrechen von Oxidschichten an eingeführten Litzen. Die Anformung einer gewindeartigen Kontur ist als lediglich beispielhaft anzusehen. Auch alle anderen Arten von scharfkantigen Konturen sind geeignet und zweckmäßig. In the interior of the connecting sleeve 4, a thread-like contour on the inner side 18 can be seen in FIG. This advantageously sharp-edged contour also serves to break up oxide layers on inserted strands. The formation of a thread-like contour is to be regarded as merely exemplary. All other types of sharp-edged contours are suitable and appropriate.
An der Außenseite der Anschlusshülse 4 sind hier vier flache Nuten 17 erkennbar. Diese dienen der Kennzeichnung der Crimpbereiche. Dem Nutzer zeigen diese Nuten 17 an, an welchen Stellen ein Crimp- oder Quetschwerkzeug angesetzt werden soll. On the outside of the connecting sleeve 4 four flat grooves 17 can be seen here. These are used to identify the crimping areas. These grooves 17 indicate to the user at which points a crimping or squeezing tool is to be applied.
Figur 3 zeigt ein elektrisches Kontaktelement 1 mit Spleißelement 10 in räumlicher Darstellung mit Blick auf die Anschlussseite 3. Erkennbar sind auch hier die vier um die Anschlusshülse 4 laufenden Nuten 17, welche als Markierung für eine Crimp- oder Quetschwerkzeug dienen. FIG. 3 shows an electrical contact element 1 with splicing element 10 in a three-dimensional view with a view of the connection side 3. The four grooves 17 running around the connection sleeve 4 can also be seen here, which serve as a marking for a crimping or crimping tool.
Zudem sind zwischen den Nuten 17 drei Abflachungen 6 erkennbar. Auch diese dienen als Markierung für ein Crimp- oder Quetschwerkzeug. Im Gegensatz zu den Nuten 17 jedoch nicht für die Position entlang des elektrischen Kontaktelements 1 , sondern für die Winkelposition des Werk- zeugs im Crimpbereich. In addition, three flats 6 can be seen between the grooves 17. These also serve as a marking for a crimping or crimping tool. In contrast to the grooves 17, however, not for the position along the electrical contact element 1, but for the angular position of the workpiece. in the crimping area.
Wird ein entsprechendes Crimpwerkzeug, welches mit seinen Crimpba- cken an die Anzahl der Spleißsegmente 1 1 angepasst ist verwendet, so markiert die Abflachung 6 die Position eines Spleißsegments 1 1 in der Anschlusshülse 4. Dadurch kann die maximale Kraft und Quetschung des Crimpwerkzeugs exakt auf die Positionen einwirken, hinter welchen jeweils ein Spleißsegment 1 1 liegt. If a corresponding crimping tool, which is adapted with its crimping jaws to the number of splice segments 11, is used, then the flattening 6 marks the position of a splicing segment 11 in the connecting sleeve 4. Thus, the maximum force and pinching of the crimping tool can be exactly matched to the crimping tool Acting positions behind each of which a splice segment 1 1 is located.
Die Figur 4 zeigt ein Spleißelement 10 in räumlicher Darstellung. Wie bereits in Figur 1 zu erkennen, besteht das Spleißelement 10 aus einer Basis 12 von welcher die Spleißsegmente 1 1 , 1 1 ', 1 1 ", 1 1 "', 1 1 "", 1 1 axial weg erstrecken. FIG. 4 shows a splicing element 10 in a spatial representation. As already seen in Figure 1, the splice element 10 consists of a base 12 from which the splice segments 1 1, 1 1 ', 1 1 ", 1 1"', 1 1 "", 1 1 extend axially away.
In der Basis 12 ist eine Gewinde 19 zu erkennen welches zur Fixierung des Spleißelements 10 mittels einer Schraube als Befestigungsmittel 13 in einem elektrischen Kontaktelement 1 dient. In the base 12, a thread 19 can be seen which serves to fix the splice element 10 by means of a screw as a fastening means 13 in an electrical contact element 1.
Die Spleißsegmente 1 1 sind im anschlussseitigen Bereich auf ihrer Innenseite angeschrägt, um das Aufstecken des Spleißelements 10 auf die Litzen eines elektrischen Leiters 20 zu vereinfachen. The splice segments 1 1 are chamfered in the connection-side region on its inner side in order to simplify the attachment of the splice element 10 to the strands of an electrical conductor 20.
In der Basis 12 verfügt das Spleißelement 10 über eine Bohrung 16. Die Bohrung 16 ist in der dargestellten Ausführungsform als seitlicher Schlitz ausgebildet. Dieser dient, um das Spleißelement 10 in der Aufnahmehülse 4 verdrehsicher zu halten. Dazu kann ein weiteres Befestigungselement in eine Bohrung 15 in der Aufnahmehülse 4 engeschoben werden. Wenn das Befestigungsmittel durch die Bohrung 15 bis in die Bohrung 16 geführt wird, ist ein Verdrehen des Spleißelements 10 in der Aufnahmehülse 4 verhindert. In the base 12, the splice element 10 has a bore 16. The bore 16 is formed in the illustrated embodiment as a lateral slot. This serves to hold the splice element 10 in the receiving sleeve 4 against rotation. For this purpose, a further fastening element can be pushed into a bore 15 in the receiving sleeve 4. When the fastener is passed through the bore 15 into the bore 16, a rotation of the splice element 10 in the receiving sleeve 4 is prevented.
Figur 5 zeigt ein elektrisches Kontaktelement 1 mit eingefügtem elektri- schem Leiter 20 in einer Schnittdarstellung. Dabei verläuft der Schnitt der Ansicht quer durch das elektrische Kontaktelement 1 . FIG. 5 shows an electrical contact element 1 with inserted electrical schematic conductor 20 in a sectional view. In this case, the section of the view extends transversely through the electrical contact element. 1
Erkennbar ist die Aufnahmehülse 4, sowie die darin aufgenommenen Spleißsegmente , 1 1 ', 1 1 ", 1 "', 1 1 "", 1 1 , welche sich an der Innenfläche 18 der Aufnahmehülse 4 über deren Umfang verteilen. Recognizable is the receiving sleeve 4, as well as the splice segments received therein, 1 1 ', 1 1 ", 1"', 1 1 "", 1 1, which are distributed over the circumference of the inner surface 18 of the receiving sleeve 4.
Im weiteren, inneren Bereich der Aufnahmehülse 4 sind viele einzelne Litzen dargestellt, die zusammen den einführten, elektrischen Leiter 20 bilden. Die einzelnen Litzen verteilen sich zwischen den Spleißsegementen 1 1 , so dass vorteilhaft ein Großteil der einzelnen Litzen in Kontakt mit einem der Spleißsegmente 1 1 steht. Je mehr einzelne Litzen mit den Spleißsegmenten 1 1 oder der Innenfläche 18 in Kontaktstehen, desto höher ist die spätere elektrische Kontaktierung. In the further, inner region of the receiving sleeve 4 many individual strands are shown, which together form the inserted, electrical conductor 20. The individual strands are distributed between the Splleißsegementen 1 1, so that advantageously a large part of the individual strands is in contact with one of the splice segments 1 1. The more individual strands are in contact with the splice segments 1 1 or the inner surface 18, the higher is the subsequent electrical contact.
Zudem ist in der Figur 5 die Abflachung 6 erkennbar. Diese dient - wie schon erwähnt - zu Markierung für ein Crimp- oder Quetschwerkzeug. Die Abflachung 6 liegt zweckmäßig direkt außerhalb eines Spleißsegments. In addition, the flattening 6 can be seen in FIG. This serves - as already mentioned - to mark a crimping or crimping tool. The flattening 6 is expediently located directly outside a splice segment.
