Description

Die Erfindung betrifft ein zylindrisches Rundsteckerge­häuse aus Kunststoff mit sich in axialer Richtung er­streckenden Kammern für die Lagerung elektrischer Steck­kontakte, vorzugsweise Rundsteckkontakte.The invention relates to a cylindrical round plug housing made of plastic with axially extending chambers for the storage of electrical plug contacts, preferably round plug contacts.

Es ist ein Rundsteckergehäuse bekannt, bei dem die Ge­häusezylinderwandung relativ dünn ist und das eine Stirnwandung aufweist. Im Inneren sind die sich axial parallel erstreckenden Kammern für je einen elektri­schen Steckkontakt auf einem Kreisbogen peripher bzw. der Zylinderwandung benachbart eingeformt. Die Kammern münden mit einer Öffnung in der Stirnwandung und rei­chen mit ihrer gegenüberliegenden Öffnung bis etwas über die Längsmitte des Rundsteckergehäuses.A round connector housing is known in which the housing cylinder wall is relatively thin and which has an end wall. Inside, the axially parallel-extending chambers for an electrical plug contact are formed on a circular arc peripherally or adjacent to the cylinder wall. The chambers open with an opening in the end wall and extend with their opposite opening to a little over the longitudinal center of the circular connector housing.

Um die Kammern z.B. zum Einsetzen der Steckkontakte zugänglich zu machen, sind die Kammerwandungen von der Stirnwand beginnend bis etwa zur Hälfte ihrer Länge längsgeteilt, wobei eine Längshälfte der Kammern an der Zylinderwandung angeordnet ist und dieser Bereich der Zylinderwandung durch zwei seitliche, sich axial paral­lel von der Stirnwandung beginnend erstreckende Trenn­fugen und einen senkrecht dazu am Umfang verlaufenden, sich von der einen zur anderen Trennfuge erstrecken­den Trennschnitt gebildet wird und durch außen ange­formte, den Trennschnitt überbrückende Scharnier­stege deckelartig an die Zylinderwandung angebunden ist. Durch diese Anordnung ergibt sich ein nach außen schwenkbares Wandungsteilstück, das durch seine nach außen geschwenkte Stellung die Kammern zum Bestücken mit elektrischen Steckkontakten zugängig macht. Nach dem Bestücken wird das Wandungsteilstück zurückgeschwenkt und mit Stütz- und Rastmitteln derart gelagert, daß ein sich ungewolltes Öffnen ausgeschlossen ist. Die Stützmittel werden aus den Scharnierstegen be­nachbarten, den Trennschnitt überragenden, an der festen Zylinderwandung außen angeformten stiftförmigen Vor­sprüngen und seitlich innen an der Trennschnittkante des klappdeckelartigen Wandungsteilstücks angeformten, den Trennschnitt überragenden, die feste Zylinderwandung innen hintergreifende stegförmige Vorsprünge gebildet. Die Rastmittel bestehen aus je einer sich in Umfangs­richtung erstreckenden, außen an der Kammerwandung der jeweils letzten Kammer einer auf dem Kreisbogen angeord­neten, mehrere Kammern aufweisenden Kammerreihe ange­formten Raststeg mit einer innenraumseitigen Rastkante, die von der Rastkante eines sich zum Innenraum erstrecken­den, am klappdeckelartigen Wandungsteilstück räumlich entsprechend angeformten Rasthakens hintergriffen wird.In order to make the chambers accessible for inserting the plug contacts, for example, the chamber walls are longitudinally divided from the front wall to about half their length, with one longitudinal half of the chambers being arranged on the cylinder wall and this area of the cylinder wall being separated by two lateral axially parallel from one another separating joints starting from the end wall and a perpendicular to the circumference extending from the one to the other separating cut is formed and is connected to the cylinder wall by lid-shaped hinge webs bridging the separating cut. This arrangement results in a wall section which can be pivoted outwards and which, due to its position pivoted outwards, makes the chambers accessible for fitting with electrical plug contacts. After assembly, the wall section is pivoted back and so with support and locking means stored that an unwanted opening is excluded. The support means are formed from the pin-shaped projections adjacent to the hinge webs, projecting beyond the separating cut, molded on the outside of the fixed cylinder wall, and integrally molded, web-shaped projections projecting laterally on the inside of the separating cut edge of the hinged cover-like wall section, projecting beyond the separating cut and engaging behind the fixed cylinder wall. The latching means each consist of a latching web, which extends in the circumferential direction and is formed on the outside of the chamber wall of the last chamber of a row of chambers arranged on the circular arc and has a plurality of chambers, with a latching edge on the interior side, which extends spatially from the latching edge of a wall section that hinges on the hinged cover appropriately molded catch hook is engaged.

Es kann geschehen, daß die Scharnierstege brechen. In diesem Fall läßt sich das klappdeckelartige Wandungs­teilstück in axial paralleler Richtung vom Gehäuse ab­ziehen oder löst sich selbständig vom Gehäuse, so daß die Kammern offenstehen und die in die Kammern einge­setzten elektrischen Kontaktelemente frei liegen.The hinge webs can break. In this case, the hinged cover-like wall section can be pulled off the housing in the axially parallel direction or detaches itself from the housing, so that the chambers are open and the electrical contact elements inserted into the chambers are exposed.

Aufgabe der Erfindung ist, eine einfache, die bekannten Rastmittel ergänzende Vorrichtung zu schaffen, mit der nach dem Brechen der Scharnierstege eine unverlierbare Halterung des klappdeckelartigen Wandungsteilstücks gewährleistet ist.The object of the invention is to provide a simple device which supplements the known latching means and with which, after breaking the hinge webs, captive mounting of the hinged wall part is ensured.

Das im wesentlichen als Hohlzylinder ausgebildete Rund­steckergehäuse 1 aus Kunststoff weist eine Zylinder­wandung 2 und eine Stirnwandung 3 auf. Die der Stirn­wandung 3 axial gegenüberliegende Seite des Rundstecker­gehäuses 1 ist offen (bei 4). Im Innenraum 5 des Rund­steckergehäuses 1 sind peripher im Bereich der Zylinder­wandung 2 in einer Reihe auf einem Kreisbogen vier neben­einander angeordnete, sich axial parallel erstreckende zylinderförmige Kammern 7 eingeformt, die mit einer Öffnung 8 in der Stirnwandung 2 und mit ihrer anderen Öffnung 9 im Innenraum ein Stück unterhalb der Längs­mitte des Rundsteckergehäuses 1 münden.The round plug housing 1 made of plastic, essentially designed as a hollow cylinder, has a cylinder wall 2 and an end wall 3. The side of the circular connector housing 1 axially opposite the end wall 3 is open (at 4). In the interior 5 of the circular connector housing 1, four adjacent, axially parallel cylindrical chambers 7 are formed in a row on a circular arc in the periphery of the cylinder wall 2, which have an opening 8 in the end wall 2 and their other opening 9 in the interior Mouth below the longitudinal center of the circular connector housing 1.

Die Kammerwandungen 10 sind beginnend etwa in der Längs­mitte bis zur Stirnwand längsgeteilt, wobei der eine Wandungsteil 11 im Innenraum 5 angeordnet ist und sich der andere Wandungsteil 12 an einem klappdeckelartigen Wandungsteilstück 13 - im folgenden Klappdeckel 13 ge­nannt - befindet.The chamber walls 10 are divided longitudinally starting approximately in the longitudinal center up to the end wall, one wall part 11 being arranged in the interior 5 and the other wall part 12 being on a hinged lid-like Wall section 13 - hereinafter called hinged lid 13 - is located.

Der Klappdeckel 13 wird durch zwei seitliche, sich axial parallel und von der Stirnwandung 3 bis etwa zur Längs­mitte erstreckende Trennfugen 14 und einen sich etwa in der Längsmitte des Rundsteckergehäuses 1 befind­lichen, von einer Trennfuge 14 zur anderen Trennfuge 14 in Umfangsrichtung verlaufenden Trennschnitt 15 gebildet, wobei sich stirnseitig noch Stirnwandungsteile 3a am Klappdeckel 13 befinden können.The hinged lid 13 is formed by two lateral separating joints 14 which extend axially parallel and from the end wall 3 to approximately the longitudinal center and a separating cut 15 which is located approximately in the longitudinal center of the circular connector housing 1 and runs in the circumferential direction from one separating joint 14 to the other separating joint 14, where the end wall parts 3a can still be located on the hinged cover 13.

Der Klappdeckel 13 ist mit zwei etwa umfangsmittig außenseitig und auf Abstand voneinander angeformten, den Trennschnitt überbrückenden Scharnierstegen 16 an die Zylinderwandung 2 angebunden, so daß er nach außen weggeschwenkt werden kann und dadurch die Kam­mern 7 von außen zugängig werden. Nach dem Zurückschwen­ken des Klappdeckels 13 sollen Stütz- und Restmittel den Klappdeckel 13 fest am Rundsteckergehäuse 1 lagern.The hinged cover 13 is connected to the cylinder wall 2 with two hinge webs 16 which are formed on the outside around the circumference and at a distance from one another and which bridge the separating cut, so that it can be pivoted outwards and the chambers 7 are thus accessible from the outside. After swiveling back the hinged cover 13, support and residual means are supposed to store the hinged cover 13 firmly on the circular connector housing 1.

Die Stützmittel bestehen - wie an sich bekannt - aus den Scharnierstegen 16 seitlich benachbart außen an der Zylinderwand 2 angeformten, den Trennschnitt 15 frei überragenden und die Außenfläche des Klappdeckels 13 hintergreifenden stiftförmigen Vorsprüngen 17 sowie aus seitlich im Bereich der Trennfugen 14 innen an der Trennschnittkante 13a angeformten, den Trennschnitt 15 übergreifenden, die feste Zylinderwandung innen hinter­greifenden stegförmigen Vorsprüngen 18.The support means consist - as is known per se - of the hinge webs 16 formed laterally adjacent on the outside of the cylinder wall 2, freely projecting beyond the separating cut 15 and engaging behind the outer surface of the hinged cover 13, and of laterally in the region of the separating joints 14 on the inside at the separating cut edge 13a molded-on, cross-section-shaped projections 18 that cross over the separating cut 15 and that engage behind the fixed cylinder wall on the inside.

Die Rastmittel sind - wie an sich bekannt - einerseits ge­bildet aus je einem sich mehr oder weniger in Umfangs­richtung erstreckenden, an der äußeren Kammerwandung der jeweils letzten außenseitigen Kammer 7 einer Kam­ merreihe 6 im Bereich der jeweiligen Trennfuge 14 ange­ordneten Raststeg 19 mit einer zylinderwandungsseitigen Anlaufschräge 20 und einer mehr oder weniger von der Zylinderwandung abgewandten Rastkante 21 sowie erfin­dungsgemäß mit einer zur Stirnwand 3 abgewandten Lager­fläche 19a.As is known per se, the latching means are formed on the one hand from a cam that extends more or less in the circumferential direction and on the outer chamber wall of the last outer chamber 7 Series 6 in the area of the respective parting line 14 arranged locking web 19 with a chamfer 20 on the cylinder wall side and a more or less facing away from the cylinder wall locking edge 21 and according to the invention with a bearing surface 3 facing away from the end wall 3.

Andererseits weisen die Restmittel einen mit dem Raststeg 19 zusammenwirkenden Rasthaken 22 auf, der jeweils kurz unterhalb eines außenseitigen Stirnwandungsteils 3a am Klappdeckel 13 an der Zylinderwandung 2 angeformt ist, sich in den Innenraum 5 erstreckt und eine rechtwinklig zur gegenüberliegenden Seite des Klappdeckels 13 ge­richtete Rastnase 24 aufweist, die außenseitig mit einer mit der Anlaufschräge 20 des Raststegs 19 zusammenwirken­den Anlaufschräge 23 und innenseitig mit einer die Rast­kante 21 des Raststegs 19 hintergreifenden Rastkante 24a ausgerüstet ist.On the other hand, the remaining means have a latching hook 22 which interacts with the latching web 19, each of which is molded onto the cylinder wall 2 just below an outer end wall part 3a on the hinged cover 13, extends into the interior 5 and has a latching nose 24 directed at right angles to the opposite side of the hinged cover 13 has on the outside with a starting slope 23 cooperating with the run-on slope 20 of the locking web 19 and on the inside with a locking edge 24a engaging behind the locking edge 21 of the locking web 19.

Darüber hinaus ist an der der Stirnwand 3 abgewandten Seite der Rastnase 24 im Bereich der Anlaufschräge 23 eine Anfasung 25 vorgesehen, die beim Zuschwenken des Klappdeckels 13 das Aneinandervorbeigleiten des Rast­stegs 19 und der Rasthakennase 24 erleichtert, wobei der Klappdeckel 13 in Pfeilrichtung 26 (Fig. 5) elastisch aufgeweitet wird und zurückfedert, wenn die Rastnasen 24 hinter die Rastkanten 21 geschnappt sind.In addition, a chamfer 25 is provided on the side of the locking lug 24 facing away from the end wall 3 in the region of the chamfer 23, which facilitates the sliding of the locking web 19 and the locking hook lug 24 towards one another when the hinged lid 13 is pivoted, the hinged lid 13 in the direction of the arrow 26 (FIG. 5) is expanded elastically and springs back when the locking lugs 24 are snapped behind the locking edges 21.

Mit den beschriebenen Mitteln wäre der Klappdeckel 13 verrastend verriegelt und könnte weder radial nach außen noch axial parallel in Richtung Stirnwand 3 abgezogen werden. Letzteres wird durch die Scharnierstege 16 ver­hindert. Brechen aber diese Scharnierstege 16, dann be­steht die Möglichkeit, den Klappdeckel 13 axial parallel in Richtung Stirnwandung 3 abzuziehen.With the means described, the hinged cover 13 would be locked in a latching manner and could not be pulled off radially outward or axially parallel in the direction of the end wall 3. The latter is prevented by the hinge webs 16. However, if these hinge webs 16 break, there is the possibility of pulling off the hinged cover 13 axially parallel in the direction of the end wall 3.

Nach der Erfindung wird dies durch den Widerlagersteg 27 verhindert. Dieser Widerlagersteg 27 ist an der trennschnittseitigen Unterkante 22a des Hakenstiels 22b des Rasthakens 22 angeformt und springt im Be­reich des Hakenstiels 22b mit einer Stegkante 27a in Richtung zur gegenüberliegenden Seite des Klappdeckels 13 etwa so weit vor wie die Rastnase 24 am Ende des Hakenstiels 22b. Im zugeklappten Zustand des Deckels 13 untergreift somit die Widerlagerstegkante 27a die Widerlagerfläche 19a des Raststegs 19 nahezu spielfrei, weil die Raum formen der Rastmittel dementsprechend aufeinander abgestimmt sind. Dabei unterstützt eine zum Rasthaken 22 gerichtete Anfesung 27b am freien Ende des Widerlagerstegs 27 das Vorbeigleiten des Raststegs 19 am Widerlagersteg 27, bevor die Wirkung der Anfa­sung 25 eintritt.According to the invention, this is prevented by the abutment web 27. This abutment web 27 is integrally formed on the lower edge 22a of the hook handle 22b of the latching hook 22 and, in the area of the hook handle 22b, jumps with a web edge 27a towards the opposite side of the hinged cover 13 approximately as far as the latch 24 at the end of the hook handle 22b. When the cover 13 is in the closed state, the abutment web edge 27a engages under the abutment surface 19a of the latching web 19 almost without play, because the space forms of the latching means are matched to one another accordingly. A chamfer 27b directed towards the latch hook 22 at the free end of the abutment web 27 supports the sliding of the latch web 19 on the abutment web 27 before the effect of the chamfer 25 occurs.

Somit gelingt es mit einfachen Mitteln, den Klappdeckel trotz verschwenkbarer Anbindung über Scharnierstege zu verrasten und zu verriegeln, daß selbst beim Brechen der Scharnierstege der Klappdeckel unverlierbar geschlossen bleibt. Beim Schließen des Klappdeckels er­leichtern insbesondere die Anfasungen 25 und 27b sowie die Anlaufschrägen 23 und 20 das Einfädeln der Rastnase und das Untergreifen der Widerlagenflächen 19a des Raststegs 19. Im Zusammenwirken mit dem elastischen Auf­weiten des Klappdeckels 13 in Pfeilrichtung 26 gelingt es, den vorspringenden Steg 27a unter die Widerlager­fläche 19e zu bringen.Thus, it is possible with simple means to latch and lock the hinged cover despite the pivotable connection via hinge webs, so that even when the hinge webs break, the hinged lid remains captively closed. When the hinged lid is closed, the chamfers 25 and 27b and the bevels 23 and 20 in particular facilitate threading the latching nose and reaching under the abutment surfaces 19a of the latching web 19. In cooperation with the elastic expansion of the hinged lid 13 in the direction of the arrow 26, the projecting web 27a succeeds to bring under the abutment surface 19e.
