Description

Die Erfindung betrifft einen Isolierkörper für einen Steckverbinder, mit mindestens einer in Umfangsrichtung offenen Aufnahme für einen Kontakt, die einen Aufnahmeraum für den Kontakt über einen Winkelbereich umgibt, der mehr als 180° und weniger als 300° beträgt.The invention relates to an insulating body for a plug connector, with at least one receptacle for a contact that is open in the circumferential direction and that surrounds a receptacle for the contact over an angular range that is more than 180 ° and less than 300 °.

Eine solche einseitig offene Aufnahme bietet den Vorteil, dass sie elastisch ist, sodass ein Kontakt in sie eingeschoben werden kann, der dann dort zuverlässig gehalten ist. Nachteilig ist allerdings, dass es unter Umständen vorkommt, dass ein Kontakt beim Einsetzen leicht schräg eingeschoben wird, sodass er sich dann nicht in der gewünschten Position konzentrisch in der Aufnahme befindet, sondern schräg sitzt.Such a receptacle, which is open on one side, offers the advantage that it is elastic, so that a contact can be pushed into it, which is then reliably held there. However, it is disadvantageous that under certain circumstances a contact is pushed in at a slight angle when it is inserted, so that it is then not in the desired position concentrically in the receptacle, but rather sits at an angle.

Es wäre grundsätzlich denkbar, zusätzliche Führungselemente im Bereich der Aufnahme vorzusehen, mit denen verhindert werden kann, dass der Kontakt falsch ausgerichtet in den Isolierkörper eingesetzt werden kann. Da allerdings in einem solchen Isolierkörper unter Umständen eine sehr hohe Anzahl von Kontakten eng nebeneinander angeordnet ist, ist der für solche Führungselemente zur Verfügung stehende Bauraum sehr eingeschränkt. Wenn Führungselemente verwendet werden, die aufgrund der Platzprobleme sehr filigran ausgeführt sind, besteht das Problem, dass sie im zur Herstellung des Isolierkörpers verwendeten Spritzgussverfahren nicht zuverlässig abgeformt werden können; zum zuverlässigen Abformen ist eine gewisse Mindestwandstärke notwendig, oder es müssen bei sehr kleinen Wandstärken sehr teure Spezialkunststoffe eingesetzt werden, die auch unter diesen Umständen zuverlässig verarbeitet werden können.In principle, it would be conceivable to provide additional guide elements in the area of the receptacle with which it can be prevented that the contact can be inserted into the insulating body in an incorrectly aligned manner. However, since a very large number of contacts may be arranged close to one another in such an insulating body under certain circumstances, the installation space available for such guide elements is very limited. If guide elements are used that are very filigree due to the space problems, the problem arises that they cannot be reliably molded in the injection molding process used to produce the insulating body; A certain minimum wall thickness is necessary for reliable molding, or very expensive special plastics must be used for very small wall thicknesses, which can also be reliably processed under these circumstances.

Aus der DE 20 2012 010 451 U1 ist ein Isolierkörper für einen Steckverbinder bekannt, der vier in Umfangsrichtung offene Aufnahmen für einen Kontakt aufweist. Einstückig mit dem Isolierkörper sind seitlich über die Aufnahmen hervorstehende Positionierungsstege vorgesehen.From the DE 20 2012 010 451 U1 an insulating body for a connector is known which has four receptacles open in the circumferential direction for a contact. Positioning webs protruding laterally over the receptacles are provided in one piece with the insulating body.

Aus der DE 196 09 625 A1 ist ein Isolierkörper für einen Steckverbinder bekannt, der mehrere in Umfangsrichtung offene Aufnahmen aufweist. An der Außenseite jeder Aufnahme sind Einschubführungen in der Form von Ausladungen vorgesehen.From the DE 196 09 625 A1 an insulating body for a connector is known which has a plurality of receptacles open in the circumferential direction. Slide-in guides in the form of projections are provided on the outside of each receptacle.

Aus der EP0078750 wird ein Steckverbinder gezeigt, der einen Isolierkörper und mindestens einen Kontaktstreifen umfasst, der einzeln und lösbar im Isolierkörper gehalten wird. Der gezeigte Isolierkörper besteht aus mindestens zwei Teilen, wobei einer der Teile Elemente zur Einzelfixierung und zum Halten der Kontakte aufweist.From the EP0078750 a connector is shown which comprises an insulating body and at least one contact strip which is held individually and releasably in the insulating body. The insulating body shown consists of at least two parts, one of the parts having elements for individual fixing and for holding the contacts.

Die Aufgabe der Erfindung besteht darin, einen Isolierkörper der eingangs genannten Art dahin gehend weiterzubilden, dass die Montagesicherheit für die Kontakte mit geringem Aufwand erhöht ist.The object of the invention is to develop an insulating body of the type mentioned at the beginning in such a way that the assembly reliability for the contacts is increased with little effort.

Zur Lösung dieser Aufgabe ist bei einem Isolierkörper der eingangs genannten Art an mindestens einem Umfangsrand der Aufnahme ein in radialer Richtung der Aufnahme elastischer Führungssteg vorgesehen, dessen Wandstärke am freien Ende größer ist als im Bereich der Anbindung an die Aufnahme, wobei die der Aufnahme zugewandte Innenfläche des Führungsstegs gekrümmt verläuft, so dass die Innenfläche großflächig, also ohne Punktkontakt, am eingesetzten Kontakt anliegt. Die Erfindung beruht auf der Erkenntnis, dass es bei einer speziellen Ausgestaltung der Führungsstege möglich ist, sie vergleichsweise filigran auszuführen, ohne dass bei der Herstellung des Isolierkörpers teure Spezialkunststoffe verwendet werden müssen. Erfindungsgemäß wurde herausgefunden, dass ein an seinem freien Ende verdickter Führungssteg zuverlässig in einem Spritzgussverfahren abgeformt werden kann, selbst wenn die Wandstärke des Führungsstegs in der Größenordnung von 0,4 bis 0,8 mm beträgt. Ein derart dünner Führungssteg kann auch bei beengten Platzverhältnissen vorgesehen werden. Der Führungssteg gewährleistet, dass der Kontakt beim Einschieben automatisch korrekt in die offene Aufnahme eintritt. Eine Fehlmontage ist dadurch verhindert.To solve this problem, an insulating body of the type mentioned at least one peripheral edge of the receptacle is provided with a guide web that is elastic in the radial direction of the receptacle, the wall thickness of which is greater at the free end than in the area of the connection to the receptacle, the inner surface facing the receptacle of the guide web is curved so that the inner surface rests against the inserted contact over a large area, i.e. without point contact. The invention is based on the knowledge that with a special configuration of the guide webs it is possible to make them comparatively filigree without having to use expensive special plastics in the manufacture of the insulating body. According to the invention it has been found that a guide web thickened at its free end can be reliably molded in an injection molding process, even if the wall thickness of the guide web is in the order of magnitude of 0.4 to 0.8 mm. Such a thin guide web can also be provided in confined spaces. The guide bar ensures that the contact automatically enters the open receptacle correctly when it is inserted. This prevents incorrect assembly.

Vorzugsweise ist vorgesehen, dass der Führungssteg an seinem freien Ende eine Wandstärke hat, die zwischen 20 % und 70 % größer ist als im Bereich der Anbindung an die Aufnahme. Diese Zunahme der Wandstärke gewährleistet, dass im Bereich des freien Endes des Führungsstegs genug Material vorhanden ist, damit dieser zuverlässig spritzgegossen werden kann.It is preferably provided that the guide web has a wall thickness at its free end which is between 20% and 70% greater than in the area of the connection to the receptacle. This increase in wall thickness ensures that there is enough material in the area of the free end of the guide bar so that it can be reliably injection molded.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind zwei einander symmetrisch gegenüberliegende Führungsstege vorgesehen. Mit zwei Führungsstegen wird ein Kontakt, wenn er in den Isolierkörper eingesetzt wird, optimal in die Aufnahme geführt.According to a preferred embodiment of the invention, two symmetrically opposite guide webs are provided. With two guide bars, a contact is optimally guided into the receptacle when it is inserted into the insulating body.

Vorzugsweise ist vorgesehen, dass die freien Enden der beiden Führungsstege einander in einem Abstand gegenüberliegen, der in der Größenordnung von 10 % bis 40 % des Durchmessers der Aufnahme beträgt. Hierdurch stellt sich dem Kontakt, wenn er in den Isolierkörper eingesetzt wird, die für ihn vorgesehene Aufnahme als nahezu geschlossen dar, wodurch das Risiko einer Fehlausrichtung verringert ist.It is preferably provided that the free ends of the two guide webs are opposite one another at a distance which is in the order of magnitude of 10% to 40% of the diameter of the receptacle. As a result, when the contact is inserted into the insulating body, the receptacle provided for it appears to be almost closed, which reduces the risk of misalignment.

Vorzugsweise ist vorgesehen, dass der Führungssteg gekrümmt ist. Dies führt zu einer gleichmäßigen Anlage des Führungsstegs am Kontakt.It is preferably provided that the guide web is curved. This leads to the guide bar resting evenly on the contact.

Vorzugsweise ist vorgesehen, dass die von der Aufnahme abgewandte Außenfläche des Führungsstegs konzentrisch zur Mittelachse der Aufnahme verläuft. Bei dieser Gestaltung der Außenfläche ergibt sich eine spritzgusstechnisch vorteilhafte Kontur des Führungsstegs.It is preferably provided that the outer surface of the guide web facing away from the receptacle runs concentrically to the central axis of the receptacle. This design of the outer surface results in a contour of the guide web that is advantageous in terms of injection molding.

Eine (zumindest nahezu) vollflächige Berührung zwischen dem Kontakt und der Innenfläche des Führungsstegs ergibt sich, wenn der Krümmungsradius der Innenfläche des Führungsstegs im Wesentlichen dem Radius der Aufnahme entspricht.An (at least almost) full-surface contact between the contact and the inner surface of the guide web results when the radius of curvature of the inner surface of the guide web essentially corresponds to the radius of the receptacle.

Die Erfindung wird nachfolgend anhand einer Ausführungsform beschrieben, die in den beigefügten Zeichnungen dargestellt ist. In diesen zeigen:

  • Figur 1 in einer perspektivischen Ansicht einen Isolierkörper mit 15 Aufnahmen für Kontakte;
  • Figur 2 in einer schematischen, perspektivischen Ansicht eine Aufnahme für einen Kontakt;
  • Figur 3 die Aufnahme von Figur 2 in einer Draufsicht;
  • Figur 4 in einer Draufsicht zwei Aufnahmen, wobei in eine der beiden Aufnahmen ein Kontakt eingesetzt ist; und
  • Figur 5 die beiden Aufnahmen von Figur 4 in einer perspektivischen Ansicht.
The invention is described below with reference to an embodiment which is shown in the accompanying drawings. In these show:
  • Figure 1 in a perspective view an insulating body with 15 receptacles for contacts;
  • Figure 2 in a schematic, perspective view a receptacle for a contact;
  • Figure 3 the inclusion of Figure 2 in a plan view;
  • Figure 4 in a plan view two recordings, a contact being inserted into one of the two recordings; and
  • Figure 5 the two recordings of Figure 4 in a perspective view.

In Figur 1 ist ein Isolierkörper 5 für einen Steckverbinder gezeigt, der mit insgesamt 15 Aufnahmen 10 für (hier nicht dargestellte) Kontakt versehen ist.In Figure 1 shows an insulating body 5 for a plug connector, which is provided with a total of 15 receptacles 10 for contact (not shown here).

Der Isolierkörper besteht aus spritzgegossenem Kunststoff.The insulating body is made of injection-molded plastic.

In den Figuren 2 und 3 ist eine der Aufnahmen 10 im Detail gezeigt. Jede Aufnahme 10 umgibt einen Aufnahmeraum 12, in den ein Kontakt mit kreisrundem Querschnitt eingesetzt werden kann. Wie anhand der in Figur 3 eingezeichneten Begrenzungslinien B zu sehen ist, umschließt die Aufnahme den Aufnahmeraum für einen Winkelbereich a, der merklich größer als 180° ist, jedoch weniger als 300° beträgt. Im gezeigten Ausführungsbeispiel liegt der Winkel α im Bereich von 210° bis 240°.In the Figures 2 and 3 one of the recordings 10 is shown in detail. Each receptacle 10 surrounds a receiving space 12 into which a contact with a circular cross section can be inserted. As with the in Figure 3 The boundary lines B drawn in can be seen, the recording encloses the recording space for an angular range a which is noticeably larger than 180 ° but is less than 300 °. In the exemplary embodiment shown, the angle α is in the range from 210 ° to 240 °.

Die Innenfläche 14 der Aufnahme hat einen (zumindest nahezu) konstanten Krümmungsradius, wobei der Krümmungsradius im Wesentlichen dem Radius des im Aufnahmeraum 12 aufzunehmenden Kontakts entspricht. Tatsächlich hat der Aufnahmeraum 12 geringfügig kleinere Abmessungen als der Querschnitt des aufzunehmenden Kontakts, sodass der Kontakt die Aufnahme 10 geringfügig elastisch aufweitet, wenn er in den Aufnahmeraum 12 eingeschoben wird.The inner surface 14 of the receptacle has an (at least almost) constant radius of curvature, the radius of curvature essentially corresponding to the radius of the contact to be made in the receptacle space 12. The receiving space 12 actually has slightly smaller dimensions than the cross-section of the contact to be received, so that the contact slightly elastically expands the receptacle 10 when it is pushed into the receiving space 12.

Ausgehend von den beiden Umfangsrändern 16 der Aufnahme 10, also dem Schnitt der Begrenzungsebenen B mit der Aufnahme, erstreckt sich hier jeweils eine Begrenzungsfläche 18. Bei der gezeigten Ausführungsform erstrecken sich die beiden Begrenzungsflächen 18 in derselben Ebene.Starting from the two peripheral edges 16 of the receptacle 10, that is to say the intersection of the delimitation planes B with the receptacle, a delimitation surface 18 each extends here.

Ausgehend von jedem Umfangsrand (und auch jeder Begrenzungsfläche 18) ist jeweils ein Führungssteg 20 vorgesehen, der die Innenfläche 14 "verlängert". Anders ausgedrückt: der Spalt S zwischen den einander gegenüberliegenden freien Enden der beiden Führungsstege 20 ist kleiner als der Abstand zwischen den beiden Umfangsrändern 16 der Aufnahme 10.Starting from each peripheral edge (and also each delimiting surface 18), a guide web 20 is provided in each case, which "extends" the inner surface 14. In other words: the gap S between the opposite free ends of the two guide webs 20 is smaller than the distance between the two peripheral edges 16 of the receptacle 10.

Wie insbesondere in Figur 2 zusehen ist, ist die Höhe der Führungsstege 20, also ihre Erstreckung entlang der axialen Richtung des Aufnahmeraums 12, kleiner als die Höhe der Aufnahme 10. Im gezeigten Ausführungsbeispiel beträgt die Höhe der Führungsstege 20 etwas mehr als die halbe Höhe der Aufnahme 10.As in particular in Figure 2 can be seen, the height of the guide webs 20, i.e. their extension along the axial direction of the receiving space 12, is less than the height of the receptacle 10. In the exemplary embodiment shown, the height of the guide webs 20 is slightly more than half the height of the receptacle 10.

Wie insbesondere in Figur 3 zu sehen ist, sind die Führungsstege 20 so ausgeführt, dass ihre Wandstärke am freien Ende größer ist als im Bereich der Anbindung an die Aufnahme 10.As in particular in Figure 3 As can be seen, the guide webs 20 are designed such that their wall thickness is greater at the free end than in the area of the connection to the receptacle 10.

Im gezeigten Ausführungsbeispiel ist die in radialer Richtung gemessene Wandstärke W am freien Ende der Führungsstege 20 in der Größenordnung von 50 % größer als die Wandstärke im Bereich des Übergangs zur Aufnahme 10, also im Bereich der Begrenzungsebene B.In the exemplary embodiment shown, the wall thickness W measured in the radial direction at the free end of the guide webs 20 is of the order of magnitude of 50% greater than the wall thickness in the area of the transition to the receptacle 10, i.e. in the area of the boundary plane B.

Wie ebenfalls in Figur 3 gut zu sehen ist, sind die Führungsstege 20 so ausgerichtet, dass ihre Innenfläche 22 innerhalb der kreiszylindrischen Kontur K liegt, die der Außenfläche eines in den Aufnahmeraum 12 eingesetzten Kontaktes entspricht.As in Figure 3 As can be clearly seen, the guide webs 20 are aligned such that their inner surface 22 lies within the circular cylindrical contour K, which corresponds to the outer surface of a contact inserted into the receiving space 12.

Anhand der Figuren 4 und 5 wird nun die Funktion der Führungsstege erläutert.Based on Figures 4 and 5 the function of the guide bars will now be explained.

In der jeweils rechten Darstellung in den Figuren 4 und 5 ist zu sehen, dass die Führungsstege 20 im Ausgangszustand, also wenn sich im Aufnahmeraum 12 der Aufnahme 10 kein Kontakt befindet, gegenüber einer kreiszylindrischen Kontur nach innen in den Aufnahmeraum 12 hineinragen. Wenn ein Kontakt 30 in den Aufnahmeraum 12 eingesetzt ist (siehe in den Figuren 4 und 5 die jeweils linke Darstellung), werden die Führungsstege 20 elastisch vom Kontakt nach außen verdrängt (siehe die Pfeile P in Figur 4 links). Hierbei üben die Führungsstege 20 eine Reaktionskraft auf den Kontakt 30 aus, die diesen hin zur von den Führungsstegen 20 abgewandten Seite des Aufnahmeraums 12 beaufschlagt. Somit ist zuverlässig gewährleistet, dass der Kontakt 30 seinen Weg in den Aufnahmeraum 12 hinein findet, auch wenn die Aufnahme 10 den Kontakt nicht vollständig über 360° umschließt, sondern über einen großen Teil seines Umfangs offen ist.In the illustration on the right in the Figures 4 and 5 it can be seen that the guide webs 20 in the initial state, that is, when there is no contact in the receiving space 12 of the receptacle 10, protrude inwardly into the receiving space 12 with respect to a circular cylindrical contour. When a contact 30 is inserted into the receiving space 12 (see in FIGS Figures 4 and 5 the left illustration), the guide webs 20 are elastically displaced outwards from the contact (see the arrows P in Figure 4 Left). In this case, the guide webs 20 exert a reaction force on the contact 30, which acts on it towards the side of the receiving space 12 facing away from the guide webs 20. This reliably ensures that the contact 30 finds its way into the receiving space 12, even if the receptacle 10 does not completely surround the contact over 360 °, but is open over a large part of its circumference.

Die maximale Wandstärke der Führungsstege 20 liegt in der Größenordnung von 0,4 bis 0,8 mm. Im bevorzugten Ausführungsbeispiel wird eine Wandstärke von 0,6 mm verwendet. Trotz dieser extrem geringen Wandstärke ermöglicht es die spezielle Form der Führungsstege 20 mit ihrem verdickten "Kopf" am freien Ende, zur Herstellung der Führungsstege 20 ein Spritzgussverfahren zu verwenden. Dies dürfte insbesondere darauf zurückzuführen sein, dass durch den engsten Querschnitt der Spritzgussform, also im Bereich der Anbindung des jeweiligen Führungsstegs an die Aufnahme 10, aufgrund des verdickten freien Endes des Führungsstegs 20 ausreichend Kunststoff strömt und es dort nicht zu einem vorzeitigen Erstarren des Kunststoffs kommt.The maximum wall thickness of the guide webs 20 is of the order of 0.4 to 0.8 mm. In the preferred embodiment, a wall thickness of 0.6 mm is used. Despite this extremely small wall thickness, the special shape of the guide webs 20 with their thickened "head" at the free end makes it possible to use an injection molding process to produce the guide webs 20. This is likely to be due in particular to the fact that sufficient plastic flows through the narrowest cross section of the injection mold, i.e. in the area of the connection of the respective guide web to the receptacle 10, due to the thickened free end of the guide web 20, and the plastic does not solidify there prematurely .
