Description

Einsatz für eine dreipolige elektrische Steckkupplung für einen elektrischen AnschlußsteckerInsert for a three-pin electrical connector for an electrical connector
B E S C H R E I B U N GDESCRIPTION
Die vorliegende Erfindung bezieht sich auf eine Steckkupplung für einen dreipoligen Anschlußstecker nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a plug-in coupling for a three-pin connector according to the preamble of claim 1.
Derartige Steckkupplungen sind auf dem US-amerikanischen und dem japanischen Markt im Gebrauch. Eine Steckkupplung nach dem Oberbegriff des Patentanspruchs wird insbesondere gezeigt in der US-PS 5,647,751. Nach dem Stand der Technik bestehen diese Steckkupplungen aus einem zweiteiligen Kunststoffkör- per, in dem die Crimpanschlußstifte für die Leiterenden ein- gelegt sind und der, nach dem die Leiterenden angecri pt, d.h. fixiert sind, umspritzt wird und so den Kern eines Griffkörpers bilden. Die Stirnseite dieses Griffkörpers weist drei im Dreieck zueinander angeordnete Stecköffnungen für die komplementär dazu angeordneten Kontaktstifte eines Anschluß- Steckers auf; einer dieser Kontaktstifte ist rund, die beiden anderen (Stromleiter-) Kontaktstifte sind rechteckig.Such plug-in couplings are used in the US and Japanese markets. A plug-in coupling according to the preamble of the claim is shown in particular in US Pat. No. 5,647,751. According to the prior art, these plug-in couplings consist of a two-part plastic body in which the crimp connection pins for the conductor ends are inserted and the one according to which the conductor ends are crimped, i.e. are fixed, overmolded and so form the core of a handle body. The end face of this grip body has three plug openings arranged in a triangle with respect to one another for the contact pins of a connecting plug arranged complementary thereto; one of these contact pins is round, the other two (current conductor) contact pins are rectangular.
Im Rahmen der Fertigung der Einsätze für die Steckkupplung haben sich in Verbindung mit dem Ancrimpen der Leiterenden Probleme dahingehend ergeben, daß es sich als schwierig erwiesen hat, den Arbeitsschritt CRIMPEN mit einem einfachen Werkzeug in einem einzigen Arbeitsgang zu realisieren. Aufgrund der An- / Zuordnung der Crimpanschlußenden in verschie- denen topologischen Ebenen bedingt einerseits ein kompliziertes Werkzeug und andererseits unterschiedliche, zum Teil diametrale, Kraftrichtungen.During the manufacture of the inserts for the plug-in coupling, problems have arisen in connection with the crimping of the conductor ends in that it has proven to be difficult to implement the CRIMPING step with a simple tool in a single operation. Due to the assignment / assignment of the crimp termination ends in different which topological levels require a complicated tool on the one hand and different, partly diametrical, directions of force on the other.
Die der vorliegenden Erfindung zugrunde liegende Aufgabe besteht darin, eine Steckkupplung der gattungsgemäßen Art anzugeben, bei der sämtliche Crimpanschlüsse in ein und derselben Ebene liegen und die somit über ein einfaches einstückiges Werkzeug in einem Arbeitsgang realisiert werden können.The object on which the present invention is based is to provide a plug-in coupling of the generic type, in which all crimp connections lie in one and the same plane and which can thus be implemented in one operation using a simple one-piece tool.
Die Lösung dieser Aufgabe wird durch die Merkmale des Patentanspruchs charakterisiert.The solution to this problem is characterized by the features of the patent claim.
Die diesbezüglich gewählte besondere Ausführungsform des Crimpanschlusses für den Schutzleiter hat sich zusätzlich als besonders vorteilhaft insoweit erwiesen, als die Steckkraft für den entsprechenden Kontaktstift des Anschlußsteckers aufgrund der Kürze des Steckweges relativ gering ist. Sowohl für die Stromleiter-Kontaktstifte, als auch für den Schutzleiter- Kontaktstift sind an den entsprechenden Partien der Steckkupplung Nasen beziehungsweise Laschen zur Realisierung einer Einführhilfe vorgesehen.The particular embodiment of the crimp connection for the protective conductor chosen in this regard has also proven to be particularly advantageous insofar as the plug-in force for the corresponding contact pin of the connector plug is relatively low due to the shortness of the plug-in path. Noses or tabs are provided on the corresponding parts of the plug-in coupling both for the current conductor contact pins and for the protective conductor contact pin in order to implement an insertion aid.

In Fig. 1 ist e n wannenformiger, aus hartelastischem Kunststoff gefertigter Grundkorper 1 dargestellt, der einerseits drei Einschnitte 2 zum Einlegen der Crimpanschlußst fte 30, 31 (vergleiche Fig. 2 / 3 / 5) aufweist. An der gegenüberliegenden Seite des Grundkorpers 1 ist eine Stirnwand 5 angeformt, die - gleichgerichtet - zu den hochgezogenen Wannen- randern 6, 7 des Grundkorpers 1 hochgezogen ist. Der Grund- korper 1 weist eine Mehrzahl von angeformten Stiften 8 und1 shows a trough-shaped basic body 1 made of hard-elastic plastic, which on the one hand has three incisions 2 for inserting the crimp connection posts 30, 31 (compare FIGS. 2/3/5). An end wall 5 is formed on the opposite side of the base body 1 and, in the same direction, is raised to the raised tub edges 6, 7 of the base body 1. The base body 1 has a plurality of molded pins 8 and
Säulen 9 auf, über die auf dem Boden des Grundkorpers 1, hier also im Wannenmnenraum 10 zwischen dem vorderen Wannenrand mit den Einschnitten 2 und der (hinteren) Stirnwand 5 separate Emlegekanale 11, 12, 13 ausgebildet werden. Der Stirnwand 5 gegenüber s nd zwei höhere Säulen 14, 15 angeformt, deren Bedeutung noch beschrieben wird.Columns 9, on which separate embedding channels 11, 12, 13 are formed on the bottom of the base body 1, here in the tub interior 10 between the front tub edge with the incisions 2 and the (rear) end wall 5. The end wall 5 is formed over two higher columns 14, 15, the meaning of which will be described below.
In der Stirnwand 5 sind im unteren, dem Wannenboden 16 benachbarten Bereich zwei rechteckige Durchtrittsoffnungen 17 vorgesehen, m die letztlich die Stromleiter-Kontaktstifte des Anschlußsteckers eingeführt werden; im oberen Bereich ist eine Durchtrittsoffnung 18 für den runden Kontaktstift (Schutzleiterstift) des Anschlußsteckers vorgesehen. Fig. 2 zeigt nebeneinander in Quasi-Montageposition einen Crimpanschlußstift 30 für einen Stromleiter, einen Crimpan- schlußstift 31 für den Schutzleiter und einen (zweiten) Crim- panschlußstift 30 für den zweiten Stromleiter. Die Crimpan- schlußstifte 30 bestehen je aus einem U-förmig gebogenen Metallstreifen, wobei an einem Ende ein Paar von Crimpkrallen 19, 20 und am anderen Ende ein Paar von seitlich und konisch abstehenden Nasen 21 ausgebildet sind. Diese Nasen 21 nehmen die rechteckigen Kontaktstifte des Anschlußsteckers auf und dienen infolge ihrer Konizität als Einführhilfe; der Abstand der U-Schenkel des Metallstreifens ist dabei so gewählt, daß die rechteckigen Stromleiter-Kontaktstifte des Anschlußstek- kers form- und kraftscchlüssig anliegen, das heißt Kontakt haben.In the end wall 5, two rectangular passage openings 17 are provided in the lower area adjacent to the trough base 16, m which ultimately the current conductor contact pins of the connector are inserted; In the upper area there is a passage opening 18 for the round contact pin (protective conductor pin) of the connector. 2 shows side by side in a quasi-assembly position a crimp connection pin 30 for a current conductor, a crimp connection pin 31 for the protective conductor and a (second) crimp connection pin 30 for the second current conductor. The crimp connection pins 30 each consist of a U-shaped metal strip, a pair of crimping claws 19, 20 being formed at one end and a pair of laterally and conically projecting lugs 21 being formed at the other end. These tabs 21 take up the rectangular contact pins of the connector and serve as an insertion aid due to their taper; the distance between the U-legs of the metal strip is chosen so that the rectangular current conductor contact pins of the connector are positively and non-positively, that is, have contact.
Der Crimpanschlußstift 31 für den Schutzleiter ist wie folgt ausgestaltet: Gemäß dem in Fig. 2 dargestellten bevorzugten Ausführungsbeispiel besteht der Crimpanschlußstift 31 aus ei- nem L-förmigen Metallteil, dessen ebene Abwicklung etwa die Gestalt eines „T" hat. Der Mittelsteg des T wird U-förmig verformt, so daß - ähnlich wie bei den Crimpanschlußstiften 30 - ein U-förmiger Metallstreifen 22 mit einem Paar von Crimpkrallen 23, 24 entsteht. Der Quersteg des „T" bildet da- bei zwei gegeneinander federnde Stege 25 aus, die endseitig zu Aufnahmekrallen 26 für den runden Kontaktstift des Anschlußsteckers verformt sind und deren Abstand zueinander dem Durchmesser des runden Schutzleiter-Kontaktstiftes entsprechend gewählt ist. An der von den Crimpkrallen 23, 24 abwei- senden Seite der Anschlußkrallen 26 ist je eine schräg nach außen gerichtete Lasche 27 ausgebildet, die dem leichteren Einführen des Schutzleiter-Kontaktstiftes dient. Aufgrund der nur geringen Kontaktlänge des Kontaktstiftes innerhalb der Aufnahmekrallen 26 der parallelen Stege 25 ist nur eine relativ geringe Steckkraft erforderlich.The crimp connection pin 31 for the protective conductor is designed as follows: According to the preferred exemplary embodiment shown in FIG. 2, the crimp connection pin 31 consists of an L-shaped metal part, the flat development of which has approximately the shape of a "T". The central web of the T becomes Deformed in a U-shape, so that - similar to the crimp connection pins 30 - a U-shaped metal strip 22 with a pair of crimping claws 23, 24 is formed. The transverse web of the "T" forms two mutually resilient webs 25, the ends are deformed into receiving claws 26 for the round contact pin of the connector and their distance from one another is selected in accordance with the diameter of the round protective conductor contact pin. On the side of the connecting claws 26 facing away from the crimping claws 23, 24, an obliquely outwardly directed tab 27 is formed, which serves to facilitate the insertion of the protective conductor contact pin. Due to the short contact length of the contact pin within the Pick-up claws 26 of the parallel webs 25 require only a relatively low insertion force.
Um zu verhindern, daß beispielsweise ein Anschlußstecker mit einem zu dicken Schutzleiter-Kontaktstift eingesteckt werden kann, gehen die Aufnahmekrallen 26 in Querstege 26' über; diese Querstege 26' schlagen letztlich an komplementären Anschlägen 29 (Fig. 5) im Inneren der Abdeckkappe 28 an. Damit werden die Aufnahmekrallen 26 gegen Überdehnung geschützt.In order to prevent, for example, a connecting plug with an excessively thick protective conductor contact pin from being inserted, the receiving claws 26 merge into transverse webs 26 ' ; these transverse webs 26 'ultimately abut complementary stops 29 (FIG. 5) inside the cover cap 28. The claws 26 are thus protected against overextension.
Die „Querschnittsform", das heißt Gestalt des Crimpanschluß- stiftes 31 für den Schutzleiter-Kontaktstift kann auch anders als L-förmig sein; denkbar ist beispielsweise auch eine Z- Form oder dergleichen.The “cross-sectional shape”, that is to say the shape of the crimp connection pin 31 for the protective conductor contact pin, can also be other than L-shaped; for example, a Z-shape or the like is also conceivable.
In Fig. 3 sind die Crimpanschlußstifte 30 und 31 eingelegt. Die beiden seitlich gelegenen Crimpanschlußstifte 30 liegen in den aus den angeformten Stiften 8 und Säulen 9, 14, 15 gebildeten Einlegekanälen 11, 12, 13 auf; der Crimpanschluß- stift 31 liegt im mittleren Einlegekanal 12 und wird mit seinen beiden federnden Stegen 25 zwischen den der Stirnwand gegenüber liegenden höheren Säulen 14, 15 abgestützt. Die an den hochstehenden Stegen 25 des L-förmigen Crimpanschlluß- stiftes 31 angeformten Aufnahmekrallen 26 liegen der Durch- trittsöffnung 18 in der Stirnwand 5 gegenüber.In Fig. 3, the crimp pins 30 and 31 are inserted. The two crimp connection pins 30 located on the side rest in the insertion channels 11, 12, 13 formed from the molded pins 8 and columns 9, 14, 15; the crimp connection pin 31 lies in the middle insertion channel 12 and is supported with its two resilient webs 25 between the higher columns 14, 15 opposite the end wall. The receiving claws 26 formed on the upstanding webs 25 of the L-shaped crimp connection pin 31 lie opposite the passage opening 18 in the end wall 5.
Fig. 4 und Fig. 5 zeigen eine zum Grundkörper 1 komplementäre Abdeckkappe 28, die so ausgebildet ist, daß sie einerseits die Einschnitte 2 für die Crimpanschlußstifte 30, 31 ab- schließt und daß sie andererseits auf den (Wannen-) Rändern 6, 7 und ringsum an der Stirnwand 5 auf- / ansteht, so daß nach dem Umspritzen des Einsatzes 50 (vergleiche Fig. 7) der Innenraum dem in eine Spritzform eingespritzten Kunststoff ge- genüber geschützt wird. Wie anhand von Fig. 2 erwähnt weist die Abdeckkappe 28 an ihrer Innenseite zwei zu den Querstegen 26' der Aufnahmekrallen 26 des Crimpanschlußsstiftes 31 komplementäre Anschläge 29 auf, die die Aufnahmekrallen 26 gegen eine Überdehnung schützen. Diese Anschläge 29 sind an den von der Stirnseite der Abdeckkappe 28 abgelegenen Enden über einen Queranschlag 29' verbunden, womit eine Abstützung für die Aufnahmekrallen 26 gegen Verkanten beim Einstecken des Anschlußsteckers gewährleistet ist.4 and 5 show a cover cap 28 which is complementary to the base body 1 and which is designed such that it closes the incisions 2 for the crimp connection pins 30, 31 on the one hand and on the other hand on the (tub) edges 6, 7 and all around on the end wall 5 so that after the insert 50 has been overmolded (see FIG. 7), the interior of the plastic injected into an injection mold is protected against. As mentioned with reference to FIG. 2, the cover cap 28 has on its inner side two stops 29 which complement the transverse webs 26 'of the receiving claws 26 of the crimp connection pin 31 and protect the receiving claws 26 against overexpansion. These stops 29 are connected at the ends remote from the end face of the covering cap 28 via a transverse stop 29 ', which ensures support for the receiving claws 26 against tilting when the connector plug is inserted.
Gemäß der Darstellung nach Fig. 6 ist die Abdeckkappe 28 auf den wannenförmigen Grundkörper 1 aufgesetzt beziehungsweise aufgeclipst, so daß nunmehr ein geschlossener Korpus / Einsatz 50 vorliegt. Nach außen stehen nur die paarweisen Crimp- krallen 19, 20 beziehungsweise 23, 24 der Crimpanschlußstifte 30, 31 ab; die Darstellung nach Fig. 6 zeigt des Montagezustand, in dem die Adern einer Versorgungsleitung eingelegt und das Crimpwerkzeug angesetzt werden.6, the cover cap 28 is placed or clipped onto the trough-shaped base body 1, so that a closed body / insert 50 is now present.
