Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Steckerhalter nach der Gattung des Hauptanspruchs.The invention relates to a connector holder according to the preamble of the main claim.

Ein derartiger Steckerhalter eines elektrischen Steckers ist beispielsweise aus der EP 0 195 472 Al bekannt.Such a connector holder of an electrical connector is known for example from EP 0 195 472 A1.

Dort sind in einem Trägerteil Steckkontakte aufgenommen, an deren rückwärtigen Enden Verbindungspunkte angebracht sind, an die die Anschlußdrähte eines mehradrigen Kabels angeschlossen werden.There, plug contacts are accommodated in a carrier part, at the rear ends of which connection points are attached, to which the connecting wires of a multi-core cable are connected.

Wird unsachgemäß am Kabel gezogen, beispielsweise bei Wartungsarbeiten an schwer zugänglichen Stellen, um den Stecker aus einer Gegenkupplung zu lösen, so wird ein Bruch der Steckkontakte vermieden, allerdings auf Kosten der Anschlußdrähte, die die Zugkraft ohne Entlastung auf die Verbindungspunkte weiterleiten, mit der Folge, daß die Bindung mit den Anschlußdrähten aufreißt und der Stecker seine Funktionsfähigkeit verliert.If the cable is improperly pulled, for example during maintenance work in hard-to-reach places, in order to detach the plug from a mating coupling, breakage of the plug contacts is avoided, but at the expense of the connecting wires, which transmit the tensile force to the connection points without relieving them, with the result that the bond with the connecting wires breaks and the plug loses its functionality.

Durch die US-PS 2 522 341 ist ein elektrischer Stecker bekannt, der ein elastisches Element aufweist, das in erster Linie zur Fixierung der Steckkontakte eines elektrischen Steckers in einer starren Führungsplatte dient. Gleichzeitig können dabei auch noch die abisolierten Endabschnitte von Anschlußdrähten eines mehradrigen Kabels an rückwärtige Enden der Steckkontakte zur Kontaktierung zwischen Führungsplatte und Steckkontakt eingespannt werden.An electrical connector is known from US Pat. No. 2,522,341 which has an elastic element which is primarily used for fixing the plug contacts of an electrical connector in a rigid guide plate. At the same time, the stripped end sections of connecting wires of a multi-core cable can also be clamped onto rear ends of the plug contacts for contacting between the guide plate and plug contact.

Elastisches Element und Führungsplatte sind zu diesem Zweck miteinander verrastbar. Eine Fixierung des weiterführenden Anschlußdrahtes ist mit dieser Ausführung nicht möglich.The elastic element and guide plate can be locked together for this purpose. A fixation of the connecting wire is not possible with this version.

Aufgabe der Erfingung ist es demgegenüber, einen Steckerhalter zu entwickeln, der eine größtmögliche Sicherheit gegen eine Unterbrechung der Verbindung zwischen Anschlußdraht und Steckkontakt bietet.In contrast, the task of the invention is to develop a plug holder which offers the greatest possible security against an interruption in the connection between the connecting wire and the plug contact.

Diese Aufgabe wird mit dem Merkmalen gemäß Anspruch 1 gelöst.This object is achieved with the features according to claim 1.

Vorteile der ErfindungAdvantages of the invention

Der erfindungsgemäße Steckerhalter mit den im Hauptanspruch aufgeführten Merkmalen hat den Vorteil, daß auch bei hohen Temperaturschwankungen und starken Erschütterungen keine Drahtbrüche auftreten und die Anschlußstellen der Drähte an den Steckkontakten nicht unterbrochen werden. Dabei ist gewährleistet, daß der Aufbau des Steckerhalters einfach ist, so daß die Herstellungskosten niedrig bleiben.The connector holder according to the invention with the features listed in the main claim has the advantage that no wire breaks occur even with high temperature fluctuations and strong vibrations and the connection points of the wires on the plug contacts are not interrupted. This ensures that the construction of the connector holder is simple, so that the manufacturing costs remain low.

Bei einem bevorzugten Ausführungsbeispiel ist das elastische Element als Gummiplatte ausgebildet, die beispielsweise von einem Deckel des Gehäuses des Steckerhalters gegen die Steckerplatte gepreßt wird und so die Anschlußdrähte in der gewünschten Position hält. Die Platte ist besonders herstell- und montierbar.In a preferred embodiment, the elastic element is designed as a rubber plate, which is pressed, for example, by a cover of the housing of the plug holder against the plug plate and thus holds the connecting wires in the desired position. The plate is particularly easy to manufacture and assemble.

Besonders bevorzugt wird ein Ausführungsbeispiel, bei dem das elastische Element als Deckel ausgebildet ist, der den Steckerhalter auf der Seite der Anschlußdrähte abschließt. Die Drähte werden von dem Deckel, der ganz oder wenigstens auf seiner den Anschlußdrähten zugewandten Seite aus elastischem Material besteht, gegen die Steckerplatte gepreßt und sicher gehalten. Auch dieses Ausführungsbeispiel zeichnet sich durch seinen einfachen und preisgünstigen Aufbau aus.An embodiment is particularly preferred in which the elastic element is designed as a cover, which closes the connector holder on the side of the connecting wires. The wires are pressed against the plug plate and held securely by the cover, which consists entirely or at least on its side facing the connecting wires of elastic material. This embodiment is also characterized by its simple and inexpensive structure.

Bei einem besonders bevorzugten Ausführungsbeispiel sind die Anschlußdrähte nicht unmittelbar an den Steckkontakten angeschlossen. Vielmehr sind mit den Steckkontakten Drahtstücke in die Steckerplatte eingegossen, deren Enden aus der Steckerplatte ragen. An diese Enden sind die Anschlußdrähte angeschlossen. Dadurch ist die Montage der Anschlußdrähte besonders einfach.In a particularly preferred embodiment, the connecting wires are not connected directly to the plug contacts. Rather, pieces of wire are cast into the plug plate with the plug contacts, the ends of which protrude from the plug plate. The connecting wires are connected to these ends. This makes the connection wires particularly easy to install.

Weiterhin wird ein Ausführungsbeispiel besonders bevorzugt, das sich durch ein an der Anschlußstelle zwischen Anschlußdraht und Steckkontakt vorgesehenes spezielles Verbindungselement auszeichnet, das mit dem rückwärtigen Ende des Steckkontakts verlötet und diffusions geschweißt an dem Anschlußdraht, der als Litze ausgeführt ist, angecrimpt ist. Dadurch ergibt sich nicht nur eine besonders sichere elektrische Verbindung; es ist überdies auch möglich, fehlerhafte Anschlüsse ohne weiteres zu reparieren, ohne den Steckerhalter zu zerstören.Furthermore, an embodiment is particularly preferred, which is characterized by a special connecting element provided at the connection point between the connecting wire and the plug contact, which is soldered to the rear end of the plug contact and diffusion-welded onto the connecting wire, which is designed as a strand. This not only results in a particularly secure electrical connection; it is also possible to easily repair faulty connections without destroying the connector holder.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruchs angegebenen Steckerhalters möglich. Als besonders vorteilhaft haben sich im Steckerhalter vorgesehene Nuten bzw. Vorsprünge erwiesen, die die Verlegung der Anschlußdrähte zu den Steckkontakten bzw. zu den Anschlußstellen erleichtern und als Formschluß eine Zugentlastung bewirken. Die Anschlußdrähte werden während der Montage sicher gehalten, so daß ein Verrutschen bzw. Beschädigungen während der Montage ausgeschlossen sind.The measures listed in the subclaims permit advantageous developments and improvements of the connector holder specified in the main claim. Grooves or projections provided in the plug holder have proven to be particularly advantageous, which facilitate the laying of the connecting wires to the plug contacts or to the connection points and, as a positive fit, bring about strain relief. The connecting wires are held securely during assembly, so that slipping or damage during assembly are excluded.

Die Erfindung wird im folgenden anhand der ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Es zeigen:

  • Figur 1 eine Draufsicht auf die Rückseite eines ersten Ausführungsbeispiels eines Steckerhalters;
  • Figur 2 einen Schnitt durch einen Steckerhalter gemäß Figur 1 und
  • Figur 3 einen Schnitt durch einen Teil eines zweiten Ausführungsbeispiels eines Steckerhalters.
The invention is explained in more detail below with reference to the drawing which shows an exemplary embodiment. Show it:
  • Figure 1 is a plan view of the back of a first embodiment of a connector holder;
  • Figure 2 shows a section through a connector holder according to Figure 1 and
  • Figure 3 shows a section through part of a second embodiment of a connector holder.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In den Figuren ist ein Steckerhalter mit sieben Steckkontakten dargestellt. Die Anzahl der Steckkontakte des Steckerhalters ist jedoch grundsätzlich beliebig.A plug holder with seven plug contacts is shown in the figures. However, the number of plug contacts of the plug holder is basically arbitrary.

Der Steckerhalter 1 in Figur 1 weist eine Steckerplatte 2 mit sieben Steckkontakten 3 auf. Die Stekkerplatte ist mit drei Bohrungen 4 versehen, die der Befestigung eines hier nicht dargestellten Deckels auf dem Steckerhalter und der Montage des zusammengebauten Steckerhalters, beispielsweise an einer Wand eines Gehäuses 10, dienen. Es sind mehrere Vorsprünge 5 zu erkennen, die in einem solchen Abstand angeordnet sind, daß zu den Steckern 3 führende Anschlußdrähte 6 in den Zwischenräumen festgeklemmt werden können. Die Vorsprünge 5 können Teile von Führungsstegen sein, die sich praktisch quer zur Verlaufsrichtung der Anschlußdrähte erstrecken.The plug holder 1 in FIG. 1 has a plug plate 2 with seven plug contacts 3. The plug plate is provided with three bores 4, which are used to fasten a cover (not shown here) to the plug holder and to mount the assembled plug holder, for example on a wall of a housing 10. Several projections 5 can be seen, which are arranged at such a distance that the connecting wires 6 leading to the plugs 3 in the gaps can be clamped. The projections 5 can be parts of guide webs which extend practically transversely to the direction of the connecting wires.

An den den Steckkontakten zugewandten Enden der Anschlußdrähte 6 sind Verbindungselemente 7 erkennbar, die an die hier als Litze ausgelegten Anschlußdrähte angeschlossen, beispielsweise angecrimpt, sind. Eine zusätzliche Sicherung durch Diffusionsschweißen kann vorgesehen werden. Die Verbindungselemente 7 sind andererseits um die rückwärtigen Enden der Steckkontakte herumgebogen und mit diesen, beispielsweise durch Löten, verbunden.At the ends of the connecting wires 6 facing the plug contacts, connecting elements 7 can be seen, which are connected, for example crimped, to the connecting wires designed here as a strand. An additional securing by diffusion welding can be provided. The connecting elements 7, on the other hand, are bent around the rear ends of the plug contacts and connected to them, for example by soldering.

An zwei Steckkontakten werden hier die Anschlußdrähte weggelassen, damit in der Steckerplatte 2 vorgesehene Nuten 8 erkennbar sind, in die die Anschlußdrähte 6 einlegbar sind.At two plug contacts, the connecting wires are omitted here, so that grooves 8 provided in the plug plate 2 can be seen, into which the connecting wires 6 can be inserted.

Aus der Figur ist ersichtlich, daß die rückwärtigen Enden der Stecker kreisrunde Ansätze 9 aufweisen. Diese Ansätze bestehen aus demselben Material wie der Steckerhalter, beispielsweise aus Kunststoff.From the figure it can be seen that the rear ends of the connectors have circular lugs 9. These approaches consist of the same material as the connector holder, for example made of plastic.

Figur 2 zeigt einen Steckerhalter 1 im Schnitt. Er ist in eine hier nur angedeutete Wand des Gehäuses 10 eingebracht und an dieser durch geeignete Befestigungsmittel, beispielsweise durch Schrauben 11, befestigt.Figure 2 shows a connector holder 1 in section. It is introduced into a wall of the housing 10, which is only indicated here, and is fastened to this by suitable fastening means, for example by screws 11.

Die in der Wand des Gehäuses 10 vorgesehene Durchgangsöffnung für den Steckerhalter 1 ist druckdicht ausgelegt. Es sind geeignete Dichtungsmaßnahmen vorgesehen. Im vorliegenden Fall ist ein O-Ring 14 in einer geeigneten Nut angeordnet.The through opening provided in the wall of the housing 10 for the plug holder 1 is designed to be pressure-tight. Suitable sealing measures are provided. In the present case, an O-ring 14 is arranged in a suitable groove.

Aus der Schnittdarstellung ist ersichtlich, daß mit den Steckkontakten 3 Drahtstücke 12 in das Material des Steckerhalters eingebracht sind. Beide Teile sind beispielsweise eingespritzt oder eingegossen. Die Drahtstücke sind mit dem rückwärtigen Ende der Steckkontakte elektrisch verbunden, beispielsweise verlötet oder angecrimpt und diffusionsgeschweißt. Vorzugsweise werden backlackbeschichtete Drähte verwendet. Die Drahtstücke sind turmartig umspritzt, so daß die Kunststoffansätze 9 entstehen, die für einen Dehnungsangleich sorgen, so daß Drahtbrüche ausgeschlossen sind. Durch die Kunststoffansätze wird auch die Abdichtlänge an den Drahtstücken 12 verlängert, und eine zu große Volumenansammlung im Steckerhalter verhindert. Dadurch werden Unebenheiten vermieden, die bei der Herstellung des Steckerhalters mit Hilfe der Spritztechnik entstehen könnten.From the sectional view it can be seen that 3 pieces of wire 12 are introduced into the material of the plug holder with the plug contacts. Both parts are injected or cast, for example. The pieces of wire are electrically connected to the rear end of the plug contacts, for example soldered or crimped and diffusion welded. Baked enamelled wires are preferably used. The pieces of wire are overmolded in a tower-like manner, so that the plastic lugs 9 are formed, which ensure expansion adjustment, so that wire breaks are excluded. The sealing lugs on the wire pieces 12 are also lengthened by the plastic lugs, and excessive volume accumulation in the plug holder is prevented. This avoids unevenness that could arise during the manufacture of the connector holder with the help of spraying technology.

Oben im Bild ist ein Anschlußdraht 6 erkennbar, der von zwei Vorsprüngen 5 geführt bzw. gehalten wird. Bei dieser Darstellung ist das Verbindungselement 7 besonders gut erkennbar.Die Verbindungselemente 7 sind jeweils an den Enden der als Litze ausgelegten Anschlußdrähte 6 angebracht, beispielsweise angecrimpt. Die Verbindungselemente sind mit den Enden der Drahtstücke 12 durch Formschluß und zusätzlich durch Verlöten verbunden. Nachdem alle Anschlußdrähte 6 mit den Drahtstücken 12 der Stecker 3 verbunden wurden, wird ein hier als Platte 13 ausgelegtes, elastisches Element zumindest über die Anschlußdrähte 6 gelegt. Die Platte kann aber auch die Anschlußstellen bzw. die Verbindungselemente 7 überspannen. Anschließend wird ein Deckel 15 mit dem Steckerhalter beispielsweise durch Verschrauben verbunden. Die elastische Platte 13 wird durch den Deckel auf die Anschlußdrähte 6 gedrückt. Durch die beispielsweise aus Gummi bestehende Platte 13 werden die Anschlußdrähte sicher gehalten, so daß Vibrationen weder zu Drahtbrüchen noch zur Unterbrechung der Anschlußstellen führen können.Above in the picture, a connecting wire 6 can be seen, which is guided or held by two projections 5. The connecting element 7 can be seen particularly well in this illustration. The connecting elements 7 are each attached, for example crimped, to the ends of the connecting wires 6 designed as a strand. The connecting elements are connected to the ends of the wire pieces 12 by positive locking and additionally by soldering. After all the connecting wires 6 have been connected to the wire pieces 12 of the plug 3, an elastic element designed here as a plate 13 is placed at least over the connecting wires 6. The plate can also be the connection points or spanning the connecting elements 7. A cover 15 is then connected to the plug holder, for example by screwing. The elastic plate 13 is pressed through the cover onto the connecting wires 6. The connecting wires are held securely by the rubber plate 13, for example, so that vibrations can neither lead to wire breaks nor to the connection points being interrupted.

Durch die spezielle Ausbildung der Verbindungselemente 7 können einzelne Anschlußdrähte, beispielsweise bei Austausch der angeschlossenen Geräte, abgelöst und durch neue ersetzt werden. Durch die spezielle Ausbildung der Kunststoffansätze an den Drahtstücken und durch die Wahl von Litze als Anschlußdrähte sowie durch die spezielle Ausbildung der Verbindungselemente wird erreicht, daß der Steckerhalter sehr widerstandsfähig gegen große Temperaturschwankungen und Vibrationen ist.Due to the special design of the connecting elements 7, individual connecting wires, for example when replacing the connected devices, can be detached and replaced by new ones. The special design of the plastic attachments on the wire pieces and the choice of stranded wire as connecting wires and the special design of the connecting elements ensure that the connector holder is very resistant to large temperature fluctuations and vibrations.

Figur 3 zeigt einen Ausschnitt eines weiteren Ausführungsbeispiels eines Steckerhalters. Gleiche Teile sind mit gleichen Bezugszeichen versehen; auf deren ausführliche Beschreibung wird verzichtet. Mit diesem Ausführungsbeispiel werden die Anschlußdrähte 6, von denen einer in der Figur dargestellt ist, von einem aus elastischem Material bestehenden Deckel 150 gegen die Steckerplatte 2 gepreßt und so vibrationssicher gehalten. Der festgeklemmte Anschlußdraht 6 ist über ein speziell ausgebildetes Verbindungselement 7 an einem Drahtstück 12 angebracht, das aus einem Kunststoffansatz 9 ragt und in einen hier nicht sichtbaren Steckkontakt 13 übergeht.Figure 3 shows a section of another embodiment of a connector holder. The same parts are provided with the same reference numerals; their detailed description is omitted. With this exemplary embodiment, the connecting wires 6, one of which is shown in the figure, are pressed against the plug plate 2 by a cover 150 made of elastic material and are thus held in a vibration-proof manner. The clamped connecting wire 6 is attached via a specially designed connecting element 7 to a piece of wire 12 which protrudes from a plastic lug 9 and merges into a plug contact 13 which is not visible here.

Auf seiner der Steckerplatte zugewandten Seite ist der Deckel 150 zumindest im Bereich der Anschlußdrähte 6 mit Vorsprüngen 151 versehen, durch die sich ein Formschluß ergibt, so daß die Drähte sicher gehalten werden. Eine axiale und/oder vertikale Bewegung der Anschlußdrähte und somit der Verbindungstelle wird vermieden, so daß Unterbrechungen durch Drahtbrücke praktisch ausgeschlossen sind. Durch die Vorsprünge 151 wird die Anpreßkraft des Deckels erhöht, ohen daß die Drähte abgequetscht werden.On its side facing the plug plate, the cover 150 is provided, at least in the region of the connecting wires 6, with projections 151, by means of which a positive connection is obtained, so that the wires are held securely. An axial and / or vertical movement of the connecting wires and thus the connection point is avoided, so that interruptions due to wire bridges are practically impossible. The contact pressure of the cover is increased by the projections 151 without the wires being squeezed off.

Aus dem oben Gesagten ergibt sich, daß der Deckel 150 gänzlich aus elastischem Material bestehen kann.It follows from the above that the cover 150 can consist entirely of elastic material.

Besonders bewährt haben sich Deckel aus thermoplastischem Material. Sie sind sehr leicht herstellbar und ihre elastischen Eigenschaften sind durch die Auswahl spezieller Thermoplaste in einem weiten Bereich auf die hier vorliegenden Gegebenheiten abstimmbar. Beispielsweise hat sich Ryton® sehr bewährt. Dieses Material zeichnet sich durch eine so große Steifigkeit aus, daß sich ein einwandfreier Formschluß des Deckels mit den Anschlußdrähten ergibt.Lids made of thermoplastic material have proven particularly useful. They are very easy to manufacture and their elastic properties can be matched to the existing conditions in a wide range through the selection of special thermoplastics. For example, Ryton® has proven very successful. This material is characterized by such a high degree of rigidity that there is a perfect positive fit between the cover and the connecting wires.

Es ist jedoch auch möglich, den Deckel lediglich auf seiner der Steckerplatte 2 zugewandten Seite mit einer elastischen Schicht zu versehen.However, it is also possible to provide the cover with an elastic layer only on its side facing the plug plate 2.

Damit der Deckel im montierten Zustand und während der Herstellung im Spritzverfahren sich nicht verzieht, können Versteifungselemente, beispielsweise Versteifungsrippen vorgesehen werden.Stiffening elements, for example stiffening ribs, can be provided so that the cover does not warp in the assembled state and during manufacture in the injection molding process.
