Description

Die Erfindung betrifft einen Steckereinsatz für ein Metallrohrgehäuse, umfassend einen Kontaktträger, von welchem Steckerstifte von einer ersten Seite und Lötanschlüsse von einer der ersten gegenüberliegenden zweiten Seite abstehen, eine in das Metallrohr einführbare und im montierten Endzustand den Kontaktträger umgebende Schutzhülse aus elektrisch nichtleitendem Material, welche sich von der ersten Seite des Kontaktträgers in einer ersten, zu den Steckerstiften parallelen Richtung mit ihrer vorderen Seite erstreckt und in einer zweiten Richtung, entgegengesetzt zur ersten, einen über die zweite Seite des Kontaktträgers überstehenden Schutzkragen bildet.The invention relates to a plug insert for a metal tube housing, comprising a contact carrier, from which plug pins protrude from a first side and solder connections from a first opposite second side, a protective sleeve which can be inserted into the metal tube and surrounds the contact carrier in the final assembled state and which is made of electrically non-conductive material extends from the first side of the contact carrier in a first direction parallel to the connector pins with its front side and in a second direction, opposite to the first, forms a protective collar projecting beyond the second side of the contact carrier.

Ein derartiger Steckereinsatz ist aus der DE-A-37 27 375 bekannt. Bei diesem ist der Kontaktträger einstückig mit der Schutzhülse ausgebildet und der Schutzkragen erstreckt sich in der zweiten Richtung um dieselbe Strecke wie die Lötanschlüsse, um ein Anlöten von Kabel an diese Lötanschlüsse noch möglich zu machen.Such a plug insert is known from DE-A-37 27 375. In this case, the contact carrier is formed in one piece with the protective sleeve and the protective collar extends in the second direction by the same distance as the solder connections in order to make it possible to solder cables to these solder connections.

Derartige Steckereinsätze sind insbesondere für Metallrohrgehäuse mit einem Innendurchmesser von weniger als 12 mm vorgesehen, so daß aufgrund der räumlichen Beengtheit bei dem Steckereinsatz gemäß dem Stand der Technik sich der Schutzkragen lediglich bis zum Ende der Lötanschlüsse erstrecken darf, um ein Anlöten von Kabeln an diese Lötanschlüsse noch zu ermöglichen.Such plug inserts are provided in particular for metal tube housings with an inner diameter of less than 12 mm, so that due to the spatial confinement of the plug insert according to the prior art the protective collar may only extend to the end of the solder connections in order to still allow cables to be soldered to these solder connections.

Diese Steckereinsätze haben somit den Nachteil, daß sie aufgrund der räumlichen Beengtheit lediglich für Kleinspannungen verwendbar sind, da die für höhere Spannungen erforderliche Luftstrecke vom Lötanschluß bis zum Metallrohrgehäuse nicht erreichbar ist.These plug inserts therefore have the disadvantage that they can only be used for extra-low voltages because of the limited space, since the air gap required for higher voltages from the solder connection to the metal tube housing cannot be reached.

Ferner ist aus der DE-A-37 30 033 ein Stecker bekannt, bei welchem ein Kontaktträger zwischen einer Innenhülse und einer mit dieser verschraubbaren Zwischenhülse gehalten ist.Furthermore, from DE-A-37 30 033 a connector is known in which a contact carrier is held between an inner sleeve and an intermediate sleeve which can be screwed to it.

Der Erfindung liegt daher ausgehend von der DE-A-37 27 375 die Aufgabe zugrunde, einen Steckereinsatz der gattungsgemäßen Art, insbesondere für Metallrohrgehäuse mit kleinen Durchmessern, vorzugsweise für Metallrohrgehäuse mit einem Innendurchmesser von 12 mm oder weniger, derart zu verbessern, daß dieser auch für hohe Isolationsspannungen, insbesondere Isolationsspannungen von 250 V und mehr, einsetzbar ist.Starting from DE-A-37 27 375, the invention is therefore based on the object of improving a plug insert of the generic type, in particular for metal tube housings with small diameters, preferably for metal tube housings with an inner diameter of 12 mm or less, in such a way that this also can be used for high insulation voltages, in particular insulation voltages of 250 V and more.

Diese Aufgabe wird bei einem Steckereinsatz der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Schutzhülse als einstückiges Teil ausgebildet ist, daß die Schutzhülse und der Kontaktträger zwei zusammensetzbare Teile sind, daß die Schutzhülse eine Aufnahme aufweist, in welche der Kontaktträger einsetzbar und fixierbar ist und daß bei in die Schutzhülse eingesetztem Kontaktträger der Schutzkragen in der zweiten Richtung über die Lötanschlüsse übersteht.This object is achieved according to the invention in a plug insert of the type described in the introduction in that the protective sleeve is designed as a one-piece part, in that the protective sleeve and the contact carrier are two parts which can be assembled, in that the protective sleeve has a receptacle in which the contact carrier can be inserted and fixed and that when the contact carrier is inserted into the protective sleeve, the protective collar projects beyond the solder connections in the second direction.

Der Vorteil der erfindungsgemäßen Lösung ist insbesondere darin zu sehen, daß trotz eines über die Lötanschlüsse in der zweiten Richtung weit überstehenden Schutzkragens noch die Möglichkeit besteht, ein Kabel in einfacher Art und Weise mit den Lötanschlüssen zu verlöten, da dies erfolgen kann bevor der Kontaktträger in die Schutzhülse eingesetzt ist.The advantage of the solution according to the invention can be seen in particular in that, despite a protective collar projecting far beyond the solder connections in the second direction, there is still the possibility of soldering a cable to the solder connections in a simple manner, since this can take place before the contact carrier in the protective sleeve is inserted.

Bei der erfindungsgemäßen Lösung ist es günstig, wenn die Schutzhülse in der ersten Richtung sich mindestens bis zu einem Ende der Steckerstifte erstreckt. Noch besser ist es, wenn er sich über diese hinaus erstreckt.In the solution according to the invention, it is advantageous if the protective sleeve extends in the first direction at least up to one end of the connector pins. It is even better if it extends beyond this.

Der Schutzkragen kann grundsätzlich beliebig weit über die Lötanschlüsse überstehen. Besonders bevorzugt ist eine Lösung, bei welcher der Schutzkragen um mindestens 5 mm über die Lötanschlüsse übersteht.The protective collar can in principle protrude as far beyond the solder connections. A solution is particularly preferred in which the protective collar projects beyond the solder connections by at least 5 mm.

Grundsätzlich kann der Kontaktträger von beiden Seiten in die Schutzhülse einführbar sein. Besonders vorteilhaft ist es jedoch, wenn der Kontaktträger von der vorderen Seite in die Schutzhülse einführbar ist.In principle, the contact carrier can be insertable into the protective sleeve from both sides. However, it is particularly advantageous if the contact carrier can be inserted into the protective sleeve from the front side.

Auch bei den Aufnahmen für den Kontaktträger sind die unterschiedlichsten Lösungen denkbar. Als besonders zweckmäßig hat es sich erwiesen, wenn die Schutzhülse als Aufnahme einen von einer Innenseite derselben abstehenden Ringbund aufweist.A wide variety of solutions are also conceivable for the receptacles for the contact carrier. It has proven to be particularly expedient if the protective sleeve has a ring collar projecting from the inside thereof as the receptacle.

Um eine definierte Festlegung des Kontaktträgers an dem Ringbund zu erreichen, ist zweckmäßigerweise vorgesehen, daß der Kontaktträger eine ringförmige, der Schutzhülse zugewandte und zur zweiten Seite hin offene Ausnehmung aufweist.In order to achieve a defined fixing of the contact carrier on the ring collar, it is advantageously provided that the contact carrier has an annular recess facing the protective sleeve and open towards the second side.

Besonders definiert kann der Kontaktträger dann fixiert werden, wenn der Bund einen konischen Sitz aufweist. Entsprechend vorteilhaft ist es daher auch, wenn die Ausnehmung eine konische dem Sitz entsprechende Ringwand aufweist.The contact carrier can be fixed in a particularly defined manner if the collar has a conical seat. It is therefore also correspondingly advantageous if the recess has a conical ring wall corresponding to the seat.

Bezüglich der Anordnung der Lötanschlüsse am Kontaktträger hat es sich als besonders vorteilhaft erwiesen, wenn, ausgehend von der zweiten Seite des Kontaktträgers, die Lötanschlüsse in der zweiten Richtung und senkrecht dazu frei zugänglich sind.With regard to the arrangement of the solder connections on the contact carrier, it has proven to be particularly advantageous if, starting from the second side of the contact carrier, the solder connections are freely accessible in the second direction and perpendicular to it.

Vorzugsweise ist hierbei der Kontaktträger so ausgebildet, daß er sich in der zweiten Richtung bis zu einer durch die zweite Seite definierten Fläche hinaus erstreckt, das heißt also keine über die zweite Seite überstehenden Bereiche aufweist.In this case, the contact carrier is preferably designed in such a way that it extends in the second direction to a surface defined by the second side, that is to say that it has no regions which protrude beyond the second side.

Bei allen vorstehend beschriebenen Ausführungsbeispielen ist es besonders vorteilhaft und wünschenswert, daß der Schutzkragen 52 über seine ganze Erstreckung in der zweiten Richtung das Metallrohrgehäuse vollständig auskleidet.In all the exemplary embodiments described above, it is particularly advantageous and desirable that the protective collar 52 completely lines the metal tube housing over its entire extension in the second direction.

Erfindungsgemäß sind die Schutzhülse und der Kontaktträger aus einem nicht leitenden Material, vorzugsweise aus Kunststoff, hergestellt.According to the invention, the protective sleeve and the contact carrier are made of a non-conductive material, preferably of plastic.

Ein Ausführungsbeispiel eines erfindungsgemäßen Steckereinsatzes für ein zylindrisches Metallrohrgehäuse 10 umfaßt eine von einem vorderen Ende 12 des Metallrohrgehäuses 10 in dieses einführbare zylindrische Schutzhülse 14, welche einen vorderen, auf einer am vorderen Ende 12 angeordneten Stirnfläche 16 im eingeschobenen Zustand aufliegenden Bund 18 aufweist. Dieser Bund 18 ist vorzugsweise mit einem mit dem Metallrohrgehäuse 10 identischen Außendurchmesser versehen. Durch diesen Bund 18 wird die Lage der Schutzhülse 14 im in Fig. 1 dargestellten eingeschobenen Zustand definiert.An exemplary embodiment of a plug insert according to the invention for a cylindrical metal tube housing 10 comprises a cylindrical protective sleeve 14 which can be inserted into this from a front end 12 of the metal tube housing 10 and which has a front collar 18 which, when inserted, rests on an end face 16 arranged at the front end 12 in the inserted state. This collar 18 is preferably provided with an outer diameter identical to the metal tube housing 10. This collar 18 defines the position of the protective sleeve 14 in the inserted state shown in FIG. 1.

Die Schutzhülse 14 ist in der Art eines Zylindermantels geformt und weist eine zylindrische Innenwandfläche 20 auf.The protective sleeve 14 is shaped in the manner of a cylinder jacket and has a cylindrical inner wall surface 20.

In diese Schutzhülse 14 ist ein als Ganzes mit 22 bezeichneter Kontaktträger von seiten des Bundes 18 einführbar, welcher eine Kontaktträgerplatte 24 umfaßt, welche im in die Schutzhülse 14 eingeschobenen Zustand eine erste, dem Bund 16 zugewandte Seite 26 und eine zweite, dem Bund 16 abgewandte Seite 28 aufweist. Ferner steht über die erste Seite 26 von der Kontaktträgerplatte 24 ein zylindrischer Ansatz 30 in Richtung des Bundes 18 vor, welcher einstückig an die Kontaktträgerplatte 24 angeformt ist und gemeinsam mit dieser eine zylindrische Außenfläche 32 bildet, mit welcher der Kontaktträger 22 an der Innenwandfläche 20 der Schutzhülse 14 geführt ist.In this protective sleeve 14, a contact carrier designated as a whole by 22 can be inserted from the side of the collar 18, which comprises a contact carrier plate 24 which, when inserted into the protective sleeve 14, has a first side 26 facing the collar 16 and a second side facing away from the collar 16 Page 28. Furthermore, on the first side 26 of the contact carrier plate 24, a cylindrical projection 30 protrudes in the direction of the collar 18, which is integrally formed on the contact carrier plate 24 and together with this forms a cylindrical outer surface 32 with which the contact carrier 22 on the inner wall surface 20 of the Protective sleeve 14 is guided.

Zur definierten Fixierung des Kontaktträgers 22 weist die Schutzhülse 14 einen von der Innenwandfläche 20 nach innen überstehenden Ringbund 33 auf, welcher auf seiner dem Bund 18 zugewandten Seite eine konisch in Richtung auf die Innenwandfläche 20 abfallende Ringfläche 34 aufweist und zusätzlich eine zur Innenwandfläche 20 parallele Innenfläche 36.For the defined fixation of the contact carrier 22, the protective sleeve 14 has an annular collar 33 projecting inwards from the inner wall surface 20, which has on its side facing the collar 18 a conical ring surface 34 falling towards the inner wall surface 20 and additionally an inner surface parallel to the inner wall surface 20 36.

Entsprechend ist die Kontaktträgerplatte 24 geformt. Sie weist eine sich an die zylindrische Außenfläche 32 anschließende konisch radial nach innen verlaufende und an der Ringfläche 34 zur Anlage bringbare Ringfläche 38 auf sowie eine sich an die Ringfläche 38 anschließende und an der Innenfläche 36 die Kontaktträgerplatte 24 zentriert haltende Außenfläche 40.The contact carrier plate 24 is shaped accordingly. It has an adjoining the cylindrical outer surface 32, a conically radially inwardly extending ring surface 38 which can be brought into contact with the annular surface 34, and an adjoining the annular surface 38 and on the inner surface 36, the outer surface 40 holding the contact carrier plate 24 centered.

Der Kontaktträger 22 ist somit vom Bund 16 her so weit in die Schutzhülse 14 einschiebbar, bis die Ringfläche 34 und die Ringfläche 38 miteinander zur Anlage kommen.The contact carrier 22 can thus be inserted into the protective sleeve 14 from the collar 16 until the annular surface 34 and the annular surface 38 come into contact with one another.

Die Position des Kontaktträgers 22 wird bestimmt durch sich von der ersten Seite 26 von der Kontaktträgerplatte 24 weg erstreckenden Steckerstifte 42, welche sich bis zum Bund 18 erstrecken sollen und vorzugsweise unmittelbar vor einer Vorderseite 44 der Schutzhülse 14 enden. Die Steckerstifte 42 erstrecken sich dabei parallel zu einer Längsachse 46 des Metallrohrgehäuses 10 und der Schutzhülse 14 in einer ersten Richtung 45, während sich die Lötanschlüsse 48 entgegengesetzt zur ersten Richtung 45 in einer zweiten Richtung 47 parallel zur Längsachse erstrecken. In dieser Richtung erstreckt sich auch ein die gesamte Innenwandfläche 20 abdeckender Schutzkragen 52.The position of the contact carrier 22 is determined by plug pins 42 which extend from the first side 26 away from the contact carrier plate 24 and which should extend to the collar 18 and preferably end directly in front of a front side 44 of the protective sleeve 14. The connector pins 42 extend parallel to a longitudinal axis 46 of the metal tube housing 10 and the protective sleeve 14 in a first direction 45, while the solder connections 48 extend opposite to the first direction 45 in a second direction 47 parallel to the longitudinal axis. A protective collar 52 covering the entire inner wall surface 20 also extends in this direction.

Des weiteren erheben sich von der zweiten Seite 28 der Kontaktträgerplatte 24 den Steckerstiften 42 zugeordnete Lötanschlüsse 48, an welche innen das Metallrohrgehäuse führende und lediglich strichpunktiert dargestellte Verbindungskabel 50 anlötbar sind.Furthermore, from the second side 28 of the contact carrier plate 24, the solder pins 48 assigned to the plug pins 42 rise, to which the connecting cable 50 which leads the metal tube housing and is only shown in broken lines can be soldered.

Der Schutzkragen 52 wird gebildet durch den sich in der zweiten Richtung 47 von der zweiten Seite 28 weg erstreckenden Abschnitt 52 der Schutzhülse 14, welcher Spannungsüberschläge von den Lötanschlüssen 48 zu dem Metallrohrgehäuse 10 verhindern soll, wobei der Schutzkragen 52 eine von einem hinteren Ende 54 der Lötanschlüsse 48 zu dem Metallrohrgehäuse 10 führende Luftstrecke L möglichst groß halten soll.The protective collar 52 is formed by the section 52 of the protective sleeve 14 which extends in the second direction 47 from the second side 28 and which is intended to prevent flashovers from the solder connections 48 to the metal tube housing 10, the protective collar 52 an air gap L leading from a rear end 54 of the solder connections 48 to the metal tube housing 10 is to be kept as large as possible.

Bevorzugterweise ist vorgesehen, daß die Luftstrecke L mehr als 5 mm beträgt. Somit erstreckt sich der Schutzkragen 52 um mindestens 5 mm von dem hinteren Ende 54 der Lötanschlüsse 48 von der zweiten Seite 28 weg in Richtung der Längsachse 46.It is preferably provided that the air gap L is more than 5 mm. The protective collar 52 thus extends at least 5 mm from the rear end 54 of the solder connections 48 away from the second side 28 in the direction of the longitudinal axis 46.

Die Montage des erfindungsgemäßen Steckereinsatzes erfolgt nun dadurch, daß zunächst bei nicht in die Schutzhülse 14 eingesetztem Kontaktträger 22 ein Verlöten der Kabel 50 mit den Lötanschlüssen 48 erfolgt, daß dann der Kontaktträger 22 vom Bund 18 her in die Schutzhülse 14 eingeführt und an dem Ringbund 32 vorzugsweise durch Preßpassung, wie in Fig. 1 dargestellt, fixiert wird.The plug insert according to the invention is now assembled by first soldering the cables 50 to the solder connections 48 when the contact carrier 22 is not inserted into the protective sleeve 14, and then inserting the contact carrier 22 from the collar 18 into the protective sleeve 14 and on the collar 32 is preferably fixed by press fitting, as shown in Fig. 1.

Alternativ kann, wie in Fig. 2 dargestellt, eine Einschnappverbindung vorgesehen sein, wozu vorzugsweise in Höhe der zweiten Seite 28 die Kontaktträgerplatte mit radial nach außen stehenden Klauen 60 versehen ist, welche in entsprechende Ausnehmungen 62 in der Innenfläche 36 des Ringbundes 32 eingreifen und damit ein Bewegen der Kontaktträgerplatte 24 in Richtung des Bundes 18 verhindern.Alternatively, as shown in FIG. 2, a snap-in connection can be provided, for which purpose the contact carrier plate is preferably provided at the level of the second side 28 with radially outwardly projecting claws 60 which engage in corresponding recesses 62 in the inner surface 36 of the collar 32 and thus prevent the contact carrier plate 24 from moving in the direction of the collar 18.

Bei einem dritten Ausführungsbeispiel, dargestellt in Fig. 3, erfolgt ein Verschweißen des Kontaktträgers 22 mit der Schutzhülse 14 im Berührungsbereich der der Innenwandfläche 20 zugewandten Außenfläche 32 des zylindrischen Ansatzes 30 mit der Innenwandfläche 20 der Schutzhülse 14, wobei eine Schweißstelle 66 entsteht, die vorzugsweise entlang der Innenwandfläche 20 umläuft.In a third exemplary embodiment, shown in FIG. 3, the contact carrier 22 is welded to the protective sleeve 14 in the contact area of the Inner wall surface 20 facing outer surface 32 of the cylindrical projection 30 with the inner wall surface 20 of the protective sleeve 14, wherein a weld 66 is formed, which preferably runs around the inner wall surface 20.

Insbesondere dann, wenn - wie in Fig. 1 dargestellt - in der Schutzhülse 14 Anzeigeelemente 68 vorgesehen sind, ist die Schutzhülse 14 aus einem durchscheinenden oder durchsichtigen Werkstoff hergestellt.In particular, if — as shown in FIG. 1 — display elements 68 are provided in the protective sleeve 14, the protective sleeve 14 is made of a translucent or transparent material.
