Eine Verbindungseinrichtung gemäß dem Oberbegriff des Patentanspruches 1 ist aus der älteren, nicht vorveröffentlichten deutschen Patentanmeldung DE 10 2012 205 932,6 bekannt. Diese Verbtndungseinrichtung besteht im Wesentlichen aus zwei Elementen, nämlich einem Clipelement und einem Sicherungselement, A connecting device according to the preamble of claim 1 is known from the older, not previously published German patent application DE 10 2012 205 932.6. This Verbtndungseinrichtung consists essentially of two elements, namely a clip element and a fuse element,
Aufgabe der Erfindung ist es, eine verbesserte Verbindungseinrichtung zu schaffen, die insbesondere für den Großserieneinsatz geeignet ist, sowie ein Verfahren zur Hersteilung einer derartigen Verbindungseinrichtung anzugeben. The object of the invention is to provide an improved connecting device, which is particularly suitable for mass production, as well as to provide a method for the production of such a connecting device.
AusgangspunW der Erfindung ist eine Verbtndungseinrichtung mit einem Clipelement, das einen in einer Radialrichtung elastischen Abschnitt aufweist, der unter elastischer Aufweitung auf ein männliches Fiiierefement aufclipbar ist. Die Verbindungseinrichtung weist ferner ein Sicherungselement auf, das in einer Aufschieberichtung auf das Clipelement aufschiebbar ist, insbesondere wenn das Clipelement auf ein männlichesThe starting point of the invention is a connecting device with a clip element, which has a section that is elastic in a radial direction and that can be clipped onto a male control element with elastic widening. The connecting device further comprises a securing element, which in a Aufschieberichtung on the clip element is pushed, especially if the clip element on a male
Fixierelement aufgeclipst ist. Das Sicherungselement weist einen hülsenartigen Abschnitt auf, der in einem auf das Clipelement aufgeschobenen Zustand von außen her an dem elastischen Abschnitt des Clipelements anliegt. Der hülsenartige Abschnitt hat die Aufgabe, zu erschweren bzw. zu verhindern, dass sich das Clipelement in Radialrichtung aufweiten kann, d.h. dass es unbeabsichtigt von dem männlichen Fixierelement abgezogen werden kann. Bei vom Cüpelement abgenommenem bzw. abgezogenem Sicherungselement kann das Clipelement aber sehr wohl wieder von dem männlichen Fixierelement abgezogen werden. Fuser is clipped. The securing element has a sleeve-like portion, which abuts in a pushed onto the clip element state from the outside to the elastic portion of the clip member. The sleeve-like portion has the task of complicating or preventing that the clip element can expand in the radial direction, i. that it can be inadvertently removed from the male fixing element. When removed from the Cüpelement or deducted fuse element but the clip element can very well be deducted again from the male fixing.
Der Kern der Erfindung besteht darin, dass das Clipelement und das Sicherungselement aus einem Kunststoffmaterial oder aus sich voneinander unterscheidenden Kunststoffmaterialien gespritzt sind. Bei dem Clipelement und bei dem Sicherungselement handelt es sich also um Spritzgussteile. The essence of the invention is that the clip element and the securing element are injection-molded from a plastic material or plastic materials differing from one another. The clip element and the securing element are therefore injection-molded parts.
Nach einer Weiterbildung der Erfindung ist ein unteres Ende des Sicherungselements über einen bei der Montage der Verbindungseinrichtung trennbaren bzw. abreißbaren, gespritzten Verbindungssteg mit einem oberen Ende des Clipelements stoffschlüssig verbunden. Im unmontierten Zustand der Verbindungseinrichtung sind das Clipelement und das Sicherungselement verliersicher über den bei der Montage abreißbaren Verbindungssteg miteinander verbunden, was insbesondere für eine Großserienfertigung von Vorteil ist. According to a development of the invention, a lower end of the securing element is integrally connected to an upper end of the clip element by way of a separable connecting web which can be separated or torn off during assembly of the connecting device. In the unmounted state of the connecting device, the clip element and the securing element are captively connected to one another via the tear-off during assembly connecting web, which is particularly for large-scale production of advantage.
Im Folgenden wird ein Verfahren zum Herstellen einer derartigen Verbindungseinrichtung beschrieben. Hierfür wird zunächst ein Spritzwerkzeug bzw. ein Spritzgusswerkzeug bereit gestellt, welches eine zur Form des Clipelements komplementäre erste Kavität und eine zur Form des Sicherungselements komplementäre zweite Kavität aufweist. Die beiden Kav'rtäten sind so zueinander angeordnet, dass ein unteres Ende des zu spritzenden Sicherungselements einem oberen Ende des zu spritzenden Clipelements zugewandt ist oder mit diesem überlappt. Die beiden Kavitäten sind über eine Verbindungskavität miteinander verbunden. Hereinafter, a method of manufacturing such a connector will be described. For this purpose, an injection molding tool or an injection molding tool is first provided, which has a first cavity complementary to the shape of the clip element and a second cavity that is complementary to the shape of the securing element. The two Kav 'rtäten are arranged to one another such that a lower end of the fuse element to be sprayed to be sprayed to an upper end of the Clipelement facing or overlapped with this. The two cavities are connected to each other via a connecting cavity.
Das Spritzwerkzeug weist ferner einen ersten Kanal auf, über den die erste Kavität mit einem Kunststoffmaterial befüllt wird. Dementsprechend weist die zweite Kavität einen zweiten Kanal auf, über den diese mit Kunststoffmatertal befüllt wird. The injection molding tool further has a first channel, via which the first cavity is filled with a plastic material. Accordingly, the second cavity has a second channel, via which it is filled with Kunststoffmatertal.
Gemäß der Erfindung wird das Befüllen der beiden Kavitäten so gesteuert, dass die beiden Kavitäten etwa zum gleichen Zeitpunkt vollständig befüllt sind, was zur Folge hat, dass in etwa gleichzeitig Kunststoffmaterial aus den beiden Kavitäten in die Verbindungskavität eintritt. Das aus jeder der beiden Kavitäten in die Verbindungskavität eindringende Kunststoffmaterial hat sich während des Spritzvorgangs bereits zumindest etwas abgekühlt, was zur Folge hat, dass der das Clipelement und das Sicherungselement verbindende Verbindungssteg eine "natürlich Schwachstelle" bildet, die bei der Montage der Verbindungseinrichtung von Hand ab- bzw. auseinander gerissen werden kann. Der Verbindungssteg hat im unmontierten Zustand der Verbindungseinrichtung die Funktion einer Verliersicherung, welche sicherstellt, dass das Clipetement und das Sicherungselement miteinander verbunden bleiben. According to the invention, the filling of the two cavities is controlled so that the two cavities are completely filled at about the same time, with the result that plastic material from the two cavities enters the connecting cavity at about the same time. The plastic material penetrating from each of the two cavities into the connecting cavity has already cooled down at least somewhat during the spraying process, with the result that the connecting web connecting the clip element and the securing element forms a "naturally weak point", which during assembly of the connecting device by hand can be torn off or torn apart. The connecting web has in the unassembled state of the connecting device the function of a captive, which ensures that the clip element and the fuse element remain connected to each other.
Es kann vorgesehen sein, dass die erste Kavität in einem ersten Werkzeugteil des Spritzwerkzeugs und die zweite Kavität in einem zweiten Werkzeugteil des Spritzwerkzeugs (Ober-/Unterwerkzeug) gespritzt wird. Die Verbindungskavität kann im Bereich der Trennebene der beiden Werkzeugteile des Spritzwerkzeugs vorgesehen sein. It may be provided that the first cavity in a first tool part of the injection molding tool and the second cavity in a second tool part of the injection molding tool (upper / lower tool) is injected. The connecting cavity can be provided in the region of the parting plane of the two tool parts of the injection molding tool.
Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. Es zeigen: Figuren 1 - 3 Verschiedene Zustände beim Herstellen einer Bauteilverbindung mit einer Verbindungseinrichtung gemäß derIn the following the invention will be explained in connection with the drawing.

Figur 1 zeigt ein erstes Blechbauteil 1, auf das eine Kugel 2, weiche als männliches Fixierelement fungiert, aufgeschweißt ist. Das Blechbauteil 1 soll mit einem zweiten Blechbauteil 3 verbunden werden, Das zweite Blechbau- feil 3 weist ein Durchgangsloch 4 auf. Zur Verbindung der beiden Bauteile 1 , 3 ist eine Verbindungseinrichtung vorgesehen, die durch ein Clipelement 5 und ein damit zusammenwirkendes Sicherungselement 6 gebildet ist. Das Clipelement 5 weist einen unteren, in einer Radialrichtung elastischen Abschnitt 5a und einen oberen, im Wesentlichen inelastischen Abschnitt 5b auf. In dem unteren Abschnitt 5a ist eine im Wesentlichen komplementär zu der Kugel 2 gestaltete kugelförmige Ausnehmung 5c vorgesehen. Der obere inelastische Abschnitt 5b weist eine umlaufende Vertiefung 5d auf, wodurch sich ein umlaufender abstehender Rand 5e ergibt. FIG. 1 shows a first sheet-metal component 1 onto which a ball 2, which acts as a male fixing element, is welded on. The sheet metal component 1 is intended to be connected to a second sheet metal component 3. The second sheet metal construction 3 has a through hole 4. To connect the two components 1, 3, a connecting device is provided, which is formed by a clip element 5 and a securing element 6 cooperating therewith. The clip member 5 has a lower, radially-elastic portion 5a and an upper, substantially inelastic portion 5b. In the lower portion 5a a substantially complementary to the ball 2 designed spherical recess 5c is provided. The upper inelastic portion 5b has a circumferential recess 5d, resulting in a circumferential protruding edge 5e.
Das Sicherungselement 6 weist einen hülsenartigen unteren Abschnitt 6a auf, dessen Innendurchmesser im Wesentlichen dem Außendurchmesser des elastischen Abschnitts 5a des Clipelements 5 entspricht, Nach innen oben stehen von dem hülsenartigen Abschnitt 6a federartige Elemente 6b, 6c ab. Radial nach außen steht von dem hülsenartigen Abschnitt 6a ein pilz- oder hutartiger Andrückrand 6d ab, der in einer Aufschieberichtung 7 bzw. entgegengesetzt dazu biegeelastisch ist. The securing element 6 has a sleeve-like lower portion 6a, the inner diameter of which essentially corresponds to the outer diameter of the elastic portion 5a of the clip element 5. Upwardly upstanding from the sleeve-like portion 6a are spring-like elements 6b, 6c. Radially outwardly from the sleeve-like portion 6a is a mushroom or hat-like Andrückrand 6d, which is in a Aufschieberichtung 7 or opposite to bending elastic.
Zum Verbinden der beiden Bauteile 1 , 3 wird zunächst das Clipelement auf die Kugel 2 aufgeciipst, was in Figur 2 dargestellt ist. Vor oder nach dem Aufclipsen des Clipelements 5 auf die Kugel 2 wird das zweite Bauteil 3 auf das erste Bauteil 1 gelegt. Anschließend wird das Sicherungselement 6 in Aufschieberichtung 7 auf das Clipelement aufgeschoben, bis, wie aus Figur 3 ersichtlich ist, die federartigen Elemente 6b, 6c in die Ausnehmung 5d des Clipelements eingerastet sind. Der Andrückrand 6d übergreift das in dem zweiten Bauteil 3 vorgesehene Loch 4 und drückt das zweite Bauteil 3 gegen das erste Bauteil 1. Die federartigen Elemente 6b, 6c verhindern ein selbsttätiges bzw. unbeabsichtigtes Abziehen des Sicherungselements 6 von dem Clipelement 5. To connect the two components 1, 3, the clip element is first brushed onto the ball 2, which is shown in FIG. Before or after clipping the clip element 5 onto the ball 2, the second component 3 is placed on the first component 1. Subsequently, the securing element 6 is pushed in Aufschieberichtung 7 on the clip element until, as can be seen from Figure 3, the spring-like elements 6b, 6c are engaged in the recess 5d of the clip element. The pressing edge 6d engages over the hole 4 provided in the second component 3 and presses the second component 3 against the first component 1. The spring-like elements 6b, 6c prevent an automatic or unintentional removal of the securing element 6 from the clip element 5.
Sehr wesentlich für die Festigkeit der Bauteilverbindung ist, dass der hülsenartige Abschnitt 6a des S icherungselements im Wesentlichen inelastisch, insbesondere in Radialrichtung, ist. Ein radiales Aufweiten des elastischen Abschnitts 5a des Clipelements und somit ein selbsttätiges Lösen des zweiten Bauteils 3 von dem ersten Bauteil 1 ist somit ausgeschlossen, solange das Sicherungselement 6 auf das Clipelement 5 aufgeschoben ist. It is very important for the strength of the component connection that the sleeve-like section 6a of the sealing element is essentially inelastic, in particular in the radial direction. A radial widening of the elastic portion 5a of the clip element and thus an automatic release of the second component 3 from the first component 1 is thus excluded as long as the securing element 6 is pushed onto the clip element 5.
Zum Aufschieben des Sicherungselements 6 auf das Clipelement 5 brauchen lediglich die federartigen Elemente 6b, 6c geringfügig elastisch deformiert werden, so dass sie, wie in Figur 3 dargestellt, in die Ausnehmung 5d einrasten können. Hierfür ist nur eine sehr geringe Montagekraft erforderlich. Ein selbsttätiges bzw. unbeabsichtigtes Abziehen des Sicherungselements 6 wird hingegen aufgrund der durch die federartigen Elemente 6b, 6c erreichten "Selbsthemmung" verhindert. For pushing the securing element 6 onto the clip element 5, only the spring-like elements 6b, 6c need to be slightly elastically deformed, so that they can latch into the recess 5d, as shown in FIG. For this only a very small installation force is required. An automatic or unintentional removal of the fuse element 6, however, is prevented due to the achieved by the spring-like elements 6b, 6c "self-locking".
Figur 4 zeigt ein Ausführungsbeispiel, bei dem auf die Innenseite der Ausnehmung 5c ein korrosionshemmendes Material 8a aufgebracht ist. Fer- ner ist auf eine das Bauteil 1 berührende Unterseite 5f des Clipelements 5 ein korrosionshemmendes Material 8b aufgebracht, Bei den korrosionshemmenden Materialien 8a, 8b kann es sich um ein blähfähiges Material handeln, d.h. um ein Material, das unter Wärmeeinwirkung (z.B. während eines Lackierungs- bzw.

In dem Unterwerkzeug 10b ist eine zu dem Clipelement 5 komplementäre zweite Kavttät 1 1b vorgesehen. Die beiden Kavititen 1a, 11b sind so angeordnet, dass ein unteres Ende des zu spritzenden Sicherungselements 6 einem oberen Ende des zu spritzenden Clipelements 5 zugewandt ist. Die beiden Kavititen 11a, 11b sind dabei über eine Verbind ungskavität 12 miteinander verbunden. FIG. 7 shows an injection tool 10, consisting of an upper tool 10a and a lower tool 10b. In the upper tool 10a a complementary to the securing element 6 Kavrtät 1 1a is provided. In the lower tool 10b a complementary to the clip element 5 second Kavttät 1 1b is provided. The two cavitites 1a, 11b are arranged so that a lower end of the fuse element 6 to be sprayed faces an upper end of the clip element 5 to be sprayed. The two Kavititen 11 a, 11 b are connected via a connection kungskität 12 together.
Über einen im Oberwerkzeug 10a vorgesehenen ersten Anguss 13a kann Kunststoffmaterial in die erste Kavität 11a eingebracht werden. Über einen im Unterwerkzeug 10b vorgesehenen zweiten Anguss 13b kann Kunststoffmaterial in die im Unterwerkzeug 10b vorgesehene zweite Kavität 11 eingebracht werden. Plastic material can be introduced into the first cavity 11a via a first sprue 13a provided in the upper tool 10a. About one Plastic material can be introduced into the second cavity 11 b provided in the lower die 10 b in the lower die 10 b.
Gemäß der Erfindung wird die Befüllung der beiden Kavitäten 11a, 11b mit Kunststoffmaterial so gesteuert, dass die beiden Kavitäten 11a, 1 1b in etwa zum gleichen Zeitpunkt voll befüllt sind und Kunststoffmaterial in etwa gleichzeitig aus den beiden Kavitäten 11 a, 1 1 b in die Verbindungskavität 12 eintritt. According to the invention, the filling of the two cavities 11a, 11b is controlled with plastic material so that the two cavities 11a, 1b are completely filled at about the same time and plastic material approximately simultaneously from the two cavities 11 a, 1 1 b in the Connecting cavity 12 occurs.
Nach dem Spritzen des Clipelements 5 und des Sicherungselements 6 sind die beiden Teile der Verbindungseinrichtung über einen Verbindungssteg (gebildet durch das Innere der Verbindungskavität) verliersicher miteinander verbunden. After spraying the clip element 5 and the securing element 6, the two parts of the connecting device via a connecting web (formed by the interior of the Verbindungskavität) captive connected to each other.
Wenn die Verbindungseinrichtung montiert werden soll, so kann zunächst das Clipelement 5 auf ein männliches Fixierelement (nicht dargestellt) aufgeclipst werden. Drückt man das Sicherungselement 6 weiter "nach unten", so reißt der Verbindungssteg zwischen dem Clipelement 5 und dem Sicherungselement 5 bei Überschreiten einer vorgegebenen Kraft ab, so dass das Sicherungselement 6 von außen her auf das Clipelement 5 aufgeschoben werden kann. If the connecting device is to be mounted, then first the clip element 5 can be clipped onto a male fixing element (not shown). If the securing element 6 is pressed further "downwards", the connecting web between the clip element 5 and the securing element 5 ruptures when a predetermined force is exceeded, so that the securing element 6 can be pushed onto the clip element 5 from the outside.
Wie bereite erwähnt, kann das Clipelement 5 aus demselben Kunststoffmaterial gespritzt werden, wie das Sicherungselement 6. Alternativ dazu können die beiden Elemente 5, 6 auch aus unterschiedlichen Kunststoffmaterialien gespritzt werden. As already mentioned, the clip element 5 can be injection-molded from the same plastic material as the securing element 6. Alternatively, the two elements 5, 6 can also be injection-molded from different plastic materials.
