Description

Die Erfindung betrifft einen vollisolierten Stecker mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen. Derartige Stecker weisen mindestens einen Steckerstift auf, der gegebenenfalls in einem isolierten Haltekörper befestigt ist. Zur Handhabung des Steckers und zur Isolation der Steckerstiftanschlüsse ist um den anschlußseitigen Teil der Steckerstifte und gegebenenfalls des Haltekörpers ein Griffkörper aus Isolierwerkstoff gespritzt. Weitverbreitet sind bei­spielsweise sogenannte Europastecker mit zwei parallel oder leicht konisch zueinander verlaufenden Stecker­stiften. Die im fertigen Zustand vom Griffkörper umgebenen Anschlußenden der Steckerstifte sind hülsenartig ausgebildet und weisen jeweils einen in ihrer Längsrichtung verlaufenden Aufnahmekanal zum Einschieben und Verkrimpen der Litze einer abisolierten Anschlußleitung auf.The invention relates to a fully insulated connector with the features specified in the preamble of claim 1. Such plugs have at least one plug pin, which is optionally attached in an insulated holding body. For handling the plug and for isolating the plug pin connections, a grip body made of insulating material is injection molded around the part of the plug pins on the connection side and, if appropriate, the holding body. So-called European plugs with two parallel or slightly tapered plug pins are widely used, for example. The connecting ends of the plug pins, which are surrounded by the handle body in the finished state, are sleeve-like and each have a receiving channel running in their longitudinal direction for inserting and crimping the strands of a stripped connecting line.

Eine derartige Verbindung zwischen einem Steckerstift und einer Anschlußleitung ist in US-PS 2 297 785 gezeigt. Der Aufnahmekanal zum Einschieben und Verkrimpen der Anschlußleitung ist in deren Einschubrichtung hintereinander in einen außenliegenden Hüllbereich größerer Querschnittsweite zur Aufnahme der isolierten Anschlußleitung und einen sich daran anschließenden, inneren, verengten Kontaktbereich kleinerer Querschnitts­weite zur Aufnahme lediglich des abisolierten Litzenendes der Anschlußleitung geteilt. Die Verkrimpung erfolgt sowohl im Hüll- als auch im Kontaktbereich des Stecker­stiftes, wodurch eine besonders innige und zugfeste Verbindung zwischen der Anschlußleitung und dem Stecker­stift erzielt wird.Such a connection between a plug pin and a connecting line is shown in US Pat. No. 2,297,785. The receiving channel for inserting and crimping the connecting line is divided in the insertion direction one after the other into an outer envelope area of larger cross-sectional width for receiving the insulated connecting line and an adjoining inner, narrowed contact area of smaller cross-sectional width for receiving only the stripped wire end of the connecting line. The crimping takes place both in the envelope and in the contact area of the connector pin, which makes it particularly intimate and resistant to tension Connection between the connecting line and the connector pin is achieved.

Die Herstellung eines vollisolierten Steckers erfolgt in aller Regel maschinell und vollautomatisch auf Fertigungsautomaten. Die jeweils an ihrem Ende abisolierten elektrischen Anschlußleitungen werden in die Aufnahmekanäle der Steckerstift-Anschlußenden eingeschoben. Danach werden die Anschlußenden mittels einer Preßvorrichtung zusammengequetscht, wodurch die Anschlußleitungen jeweils mit den Steckerstiften verkrimpt, also daran fixiert werden. Als letzter Fertigungsschritt wird der Griffkörper umspritzt.The manufacture of a fully insulated connector is usually done automatically and fully automatically on production machines. The electrical connection lines, which are stripped at their ends, are inserted into the receiving channels of the plug pin connection ends. The connection ends are then squeezed together by means of a pressing device, as a result of which the connection lines are each crimped with the plug pins, that is to say fixed to them. As the last manufacturing step, the handle body is overmolded.

Bei diesem vollautomatischen Fertigungsverfahren läßt es sich nicht vermeiden, daß beispielsweise wegen eines gestörten Litzengefüges seitlich wegstehende Einzeladern der Litze nicht mit in den Aufnahmekanal eingetrichtert, sondern von dem den Hüllbereich bildenden, hülsenartigen Anschlußende des Steckerstiftes entgegen der Einschieberichtung umgebogen werden. Da der Hüllbereich kürzer als die Abisolierlänge ist, schaut das Adernende nach dem Einschieben der Anschlußleitung aus dem Aufnahmekanal heraus und kann beispielsweise im rechten Winkel zur Steckerstift-­Längsachse radial abstehen.In this fully automatic manufacturing process, it cannot be avoided that, for example, due to a disturbed strand structure, individual wires of the strand which protrude laterally do not become funneled into the receiving channel, but instead are bent against the insertion direction by the sleeve-like connecting end of the plug pin forming the envelope region. Since the envelope area is shorter than the stripping length, the wire end looks out of the receiving channel after the connecting cable has been inserted and can protrude radially, for example, at right angles to the longitudinal axis of the plug pin.

Im ungünstigsten Falle kann ein im praktischen Einsatz unter Spannung stehendes Litzenaderende an der Oberfläche des umspritzten Griffkörpers zutage treten. Die damit verbundene, tödliche Gefahr für den Benutzer ist offensichtlich und kann nur durch entsprechend hohen Prüfaufwand während oder nach der Fertigung vermieden werden.In the worst case, a stranded wire end, which is under tension in practical use, can come to light on the surface of the molded grip body. The associated fatal danger to the user is obvious and can only be avoided by a correspondingly high level of testing during or after production.

Davon ausgehend liegt der Erfindung die Aufgabe zu­grunde, einen Stecker zu schaffen, bei dem die herkömmliche Verbindung zwischen Anschlußleitung und Steckerstift sicherheitstechnisch verbessert ist, so daß die beschriebene Gefahrenquelle rein durch konstruktive Maßnahmen grundsätzlich ausgeschaltet ist. Eine aufwendige Prüfung und die Investition von entsprechenden Prüfgeräten kann entfallen.Based on this, the present invention seeks to provide a connector in which the Conventional connection between the connecting line and the plug pin is improved in terms of safety technology, so that the source of danger described is basically eliminated purely by design measures. A complex test and the investment of appropriate test equipment can be omitted.

Diese Aufgabe wird durch eine Ausgestaltung des Steckers gemäß dem kennzeichnenden Merkmal des Anspruches 1 gelöst. Demnach weist zumindest der Hüllbereich eine Länge auf, die gleich groß wie oder größer als die Abisolierlänge des Litzenendes der Anschlußleitung ist. Wird das Litzenende mit einer abstehenden Litzenader nun in den Aufnahmekanal eingeschoben, so wird die Ader zwar entgegen der Einschieberichtung umgebogen, liegt aber nach vollendeter Einschiebebewegung auf ihrer ganzen Länge innerhalb des Hüllbereiches, kann also nicht aus dem Aufnahmekanal herausstehen. Damit ist die Gefahr grundsätzlich gebannt, daß eine Litzenader bis zur Oberfläche des Griffkörpers durchtreten kann.This object is achieved by an embodiment of the plug according to the characterizing feature of claim 1. Accordingly, at least the envelope region has a length which is the same size as or greater than the stripping length of the stranded end of the connecting line. If the end of the stranded wire is now inserted into the receiving channel with a projecting stranded wire, the wire is bent in the opposite direction to the insertion direction, but after the insertion movement has been completed, it lies within its entire length within the envelope area and cannot therefore protrude from the receiving channel. This basically eliminates the risk that a stranded wire can penetrate to the surface of the handle body.

Es ist darauf hinzuweisen, daß die erfindungsgemäße Ausgestaltung des Anschlußendes nicht nur bei Stecker­stiften, sondern auch bei Steckbuchsen oder anderen elektrischen Anschlußorganen vorteilhaft anwendbar ist.It should be pointed out that the design of the connection end according to the invention can be used advantageously not only with plug pins but also with plug sockets or other electrical connection elements.

Durch die Anpassung des Innendurchmessers des Kontakt­bereiches des Aufnahmekanals an den Litzendurchmesser der Anschlußleitung gemäß Anspruch 2 ist eine besonders gute Kontaktgabe im Kontaktbereich gewährleistet, da die Litze quasi rundum an der Innenwand-Kontaktfläche des Aufnahmekanals anliegt. Da gleichzeitig die Länge des Kontaktbereiches gleich groß wie oder größer als die Abisolierlänge des Litzenendes ist, kann die Anschlußleitung mit der vollen Länge ihres abisolierten Litzenendes in den Aufnahmekanal eingeschoben werden. Damit liegt die Anschlußleitung sauber im Aufnahmekanal ein, eine zuverlässige Kontakt­gabe, feste Halterung und größte Sicherheit ist damit gegeben, daß keine Litzenader an die Oberfläche des anschließend umspritzten Griffkörpers durchtritt.By adapting the inner diameter of the contact area of the receiving channel to the wire diameter of the connecting line, particularly good contact is ensured in the contact area, since the wire bears almost all around on the inner wall contact surface of the receiving channel. Since at the same time the length of the contact area is equal to or greater than the stripping length of the strand end, the connecting line can run into the receiving channel with the full length of its stripped strand end be inserted. So that the connecting cable lies cleanly in the receiving channel, reliable contact, firm mounting and maximum security is ensured that no stranded wire passes through to the surface of the subsequently molded handle body.

Durch die trichterartig ausgebildete Durchmesserstufe zwischen dem Hülsen- und Kontaktbereich wird eine ringförmige Anschlagfläche für die litzenendseitige Randkante der Isolationshülle der Anschlußleitung gebildet. Beim Einführen der Anschlußleitung in den Aufnahmekanal wird das Erreichen der Einschiebeend­stellung durch einen deutlichen Widerstand angezeigt, was vorteilhaft bezüglich der maschinellen Fertigung des Steckers ist. Über den mechanischen Widerstand kann das die Einschiebebewegung der Anschlußleitung hervorrufende Maschinenteil gesteuert werden. Durch die trichterartige Ausbildung der Durchmesserstufe kann die Litze unbehindert in den Kontaktbereich des Aufnahmekanals hineingleiten, wodurch eine Störung des Litzengefüges an sich bereits vermieden wird.Due to the funnel-like diameter step between the sleeve and contact area, an annular stop surface is formed for the edge edge of the insulation sleeve of the connecting line on the strand end. When the connecting line is inserted into the receiving channel, the reaching of the insertion end position is indicated by a clear resistance, which is advantageous with regard to the mechanical production of the connector. The machine part causing the insertion movement of the connecting line can be controlled via the mechanical resistance. Due to the funnel-like design of the diameter step, the strand can slide freely into the contact area of the receiving channel, whereby a disturbance of the strand structure itself is already avoided.

Die an sich bekannte, doppelte Verkrimpung der Anschluß­leitung mit dem Steckerstift in dessen Kontakt- und Hüllbereich ermöglicht auch beim Erfindungsgegenstand eine besonders feste Verbindung zwischen der Anschluß­leitung und dem Steckerstift. Das elastische Isolier­material der Isolationshülle schmiegt sich an der zweiten Verkrimpungsstelle im Hüllbereich förmlich an die verquetschte Innenwand des Aufnahmekanals an, wodurch eine besonders innige Verbindung zwischen der Anschlußleitung und der Aufnahmebohrung gewährleistet ist. Der erreichbare Abzugswert wird damit erheblich verbessert, was die Langlebigkeit und Zuverlässigkeit des erfindungsgemäßen Steckers verbessert.The known double crimping of the connecting line with the plug pin in its contact and envelope area also enables a particularly firm connection between the connecting line and the plug pin in the subject matter of the invention. The elastic insulating material of the insulating sleeve nestles at the second crimping point in the envelope area formally against the squeezed inner wall of the receiving channel, thereby ensuring a particularly intimate connection between the connecting line and the receiving bore. The achievable deduction value is thus significantly improved, which improves the longevity and reliability of the connector according to the invention.

Die Erfindung wird in einem Ausführungsbeispiel anhand der beiliegenden Figuren näher erläutert. Es zeigen:

  • Fig. 1 eine Seitenansicht in teilweise vertikal geschnittener Darstellung einer aus zwei Steckerstiften und einem Haltekörper gebildeten Steckerbrücke für einen sogenannten Europa­stecker,
  • Fig. 2 eine Seitenansicht gemäß Fig. 1 mit in die Aufnahmekanäle eingeschobenen Anschlußleitungen.
The invention is explained in more detail in an exemplary embodiment with reference to the attached figures. Show it:
  • 1 is a side view in a partially vertical section showing a plug bridge formed from two plug pins and a holding body for a so-called European plug,
  • Fig. 2 is a side view of FIG. 1 with connecting lines inserted into the receiving channels.

In einem Fertigungszwischenschritt liegt der Europa­stecker als Steckerbrücke 1 vor, wie sie in Fig. 1 gezeigt ist. Die Steckerbrücke 1 besteht aus einem im vertikalen Längsschnitt etwa U-förmigen Haltekörper 2 und den beiden metallischen Steckerstiften 3. Der Haltekörper 2 ist aus einem spritzbaren Kunststoff­material einstückig gefertigt und hält in seinen beiden U-Schenkeln 4 formschlüssig die Steckerstifte 3 parallel zueinander fest. Die stegartige U-Basis 5 legt den Abstand der beiden Steckerstifte 3 fest. Die in Einschubrichtung 6 vorne liegenden Einsteckenden 7 der Steckerstifte 3 stehen koaxial aus den U-Schenkeln 4 des Haltekörpers 2 heraus und sind in die Einsteck­öffnungen einer Steckdose (nicht dargestellt) einführbar.In an intermediate production step, the European plug is present as a plug bridge 1, as shown in FIG. 1. The plug bridge 1 consists of a vertical U-shaped holding body 2 and the two metal plug pins 3. The holding body 2 is made in one piece from a sprayable plastic material and holds the plug pins 3 in a form-fitting manner parallel to one another in its two U-legs 4. The web-like U-base 5 defines the distance between the two connector pins 3. The insertion ends 7 of the connector pins 3 located at the front in the insertion direction 6 project coaxially from the U-legs 4 of the holding body 2 and can be inserted into the insertion openings of a socket (not shown).

Die hülsenartigen Anschlußenden 8 der Steckerstifte 3 sind jeweils in ihrer Längsrichtung mit einem Auf­nahmekanal 9 versehen, in den jeweils die Litze 10 einer abisolierten Anschlußleitung 11 eingeschoben ist. Eine feste Verbindung zwischen Litze 10 und Steckerstift 3 ist durch eine Verkrimpung gewährleistet (nicht dargestellt), was im wesentlichen einer Verquet­schung des hülsenartigen Anschlußendes 8 mit der Litze 10 entspricht.The sleeve-like connecting ends 8 of the plug pins 3 are each provided in their longitudinal direction with a receiving channel 9, into each of which the wire 10 of a stripped connecting line 11 is inserted. A firm connection between the strand 10 and the plug pin 3 is ensured by crimping (not shown), which essentially corresponds to a squeezing of the sleeve-like connection end 8 with the strand 10.

In Fig. 2 ist dargestellt, wie die Anschlußleitung 11 zusätzlich zur Litze 10 mit dem anschlußseitigen Randbereich 12 ihrer Isolationshülle 13 in den Aufnahme­kanal 9 eingeschoben ist. Der Randbereich 12 liegt dabei mit seinem Umfang flächig-formschlüssig an der Innenwand 14 des Aufnahmekanals 9 an.FIG. 2 shows how the connecting line 11 is inserted into the receiving channel 9 in addition to the strand 10 with the edge region 12 of its insulation sleeve 13 on the connection side. The periphery of the edge region 12 lies flat against the inner wall 14 of the receiving channel 9.

Wie in den Schnittdarstellungen gezeigt, ist der Aufnahmekanal 9 in seiner Tiefe vergrößert. Er erstreckt sich bis in den vom Haltekörper 2,2ʹ umgebenen Teil der Steckerstifte 3. Dadurch ist für eine vorgegebene Hülsenlänge 16 und Abisolierlänge 17 des Litzenendes 24 der Anschlußleitung 11 das Einschieben des anschluß­seitigen Randbereiches 12 der Anschlußleitung 11 in den Aufnahmekanal 9 möglich. Nicht dargestellt ist eine bevorzugte Ausführungsform, in der lediglich die Hülsenlänge 16 vergrößert ist, wodurch ebenfalls ein Einschieben des Randbereiches 12 der Isolationshülle 13 ermöglicht wird.As shown in the sectional views, the receiving channel 9 is enlarged in depth. It extends into the part of the connector pins 3 surrounded by the holding body 2, 2 '. This makes it possible for a predetermined sleeve length 16 and stripping length 17 of the stranded end 24 of the connecting line 11 to insert the edge region 12 of the connecting line 11 into the receiving channel 9. A preferred embodiment is not shown, in which only the sleeve length 16 is increased, which likewise enables the edge region 12 of the insulation sleeve 13 to be inserted.

Der Aufnahmekanal 9 ist zur beschriebenen Erhöhung der Isolationssicherheit und für eine optimale Kontakt­gabe und Verankerung der Anschlußleitung 11 am Stecker­stift 3 in zwei Bereiche geteilt. Es sind dies der bezüglich der Einsteckrichtung 6 innenliegende, im Durchmesser dem Litzendurchmesser 22 entsprechende Kontaktbereich 18 und der äußere, radial erweiterte, im Durchmesser dem Außendurchmesser 23 der Anschluß­leitung 11 mit Isolationshülle 13 entsprechende Hüll­bereich 19. Die Längen von Kontakt- 18 und Hüllbereich 19 sind jeweils größer als die Abisolierlänge 17 des Litzenendes 24 der Anschlußleitung. Bei maximal eingeschobener Anschlußleitung 11 kommt das abisolierte Litzenende 24 im Kontaktbereich 18 des Aufnahmekanals 9 zu liegen, während der Randbereich 12 der Isolations­hülle 13 im Hüllbereich 19 angeordnet ist. Durch eine Verkrimpung im Kontaktbereich 18 wird eine optimale Kontaktgabe und Abzugssicherung für die Anschlußleitung am Steckerstift 3 gewährleistet. Eine weiter verbesserte Halterung ist durch eine zusätzliche Verkrimpung im Hüllbereich 19 möglich.The receiving channel 9 is divided into two areas in order to increase the insulation security and for optimum contact and anchoring of the connecting line 11 on the plug pin 3. These are the contact area 18 which is on the inside with respect to the insertion direction 6 and which corresponds to the diameter of the stranded wire diameter 22 and the outer, radially widened sleeve area 19 which corresponds to the diameter of the outer diameter 23 of the connecting line 11 with the insulation sleeve 13. The lengths of the contact 18 and sleeve area 19 are each greater than the stripping length 17 of the strand end 24 of the connecting line. When the connecting line 11 is pushed in to the maximum, the stripped wire end 24 comes to rest in the contact area 18 of the receiving channel 9, while the edge area 12 of the insulation sleeve 13 is arranged in the sleeve area 19. By crimping in the contact area 18 is an optimal Contacting and fuse protection for the connecting line on connector pin 3 guaranteed. A further improved mounting is possible by additional crimping in the envelope area 19.

Durch die Ausbildung des Aufnähmekanals 9 und die entsprechende mechanische und elektrische Verbindung zwischen Anschlußleitung 11 und Steckerstift 3 wird eine abstehende Litzenader 15 (in Fig. 2 übertrieben stark herausgezeichnet) immer parallel zur Steckerstift-­Längsrichtung nach hinten umgebogen und liegt grund­sätzlich innerhalb des Hüllbereiches 19. Sie kann damit nicht radial in Richtung Oberfläche des strichliert dargestellten Griffkörpers 21 abstehen, der nach der Verkrimpung der Anschlußleitungen 11 mit den Steckerstiften 3 um die gesamte Baugruppe zur griff­seitigen Vollisolation des Steckers gespritzt wird.Due to the design of the receiving channel 9 and the corresponding mechanical and electrical connection between the connecting line 11 and the plug pin 3, a protruding stranded wire 15 (exaggerated in FIG. 2) is always bent backwards parallel to the longitudinal direction of the plug pin and is basically within the envelope region 19. You can not protrude radially in the direction of the surface of the handle body 21 shown in dashed lines, which is injected after crimping the connecting lines 11 with the connector pins 3 around the entire assembly for handle-side full insulation of the connector.

Zur besseren Einschiebbarkeit der Anschlußleitung 11 in den Aufnahmekanal 9 ist die Durchmesserstufe 20 zwischen Kontaktbereich 18 und Hüllbereich 19 trichterartig ausgebildet. Die Durchmesserstufe 20 ist gleichzeitig ein Endanschlag für die Stirnkante der Isolationshülle 13 und damit für die Einschiebe­bewegung der Anschlußleitung 11 bei der maschinellen Fertigung.For better insertion of the connecting line 11 into the receiving channel 9, the diameter step 20 between the contact area 18 and the cladding area 19 is funnel-shaped. The diameter step 20 is at the same time an end stop for the front edge of the insulation sleeve 13 and thus for the insertion movement of the connecting line 11 in the case of machine production.
