Die Erfindung betrifft einen Leiterplattensteckverbinder, umfassend ein Gehäuse und eine Anzahl von Kontaktelementen, wobei jedes Kontaktelement einen Kontakt zum Anschließen von Adern und einen Kontakt zum Verbinden mit einer Leiterplatte umfasst.The invention relates to a printed circuit board connector, comprising a housing and a number of contact elements, wherein each contact element comprises a contact for connecting wires and a contact for connection to a printed circuit board.
Aus der DE 102 57 308 B3 ist ein Steckverbinder für Leiterplatten bekannt, umfassend eine Anzahl von Kontaktelementen, wobei die Kontaktelemente jeweils zwei Anschlussseiten aufweisen, wobei die eine Anschlussseite als Schneid-Klemm-Kontakt zum Anschließen von Adern und die andere Anschlussseite als Gabelkontakt zum Kontaktieren von Anschlussflächen auf einer Leiterplatte ausgebildet ist, und ein Kunststoffgehäuse, in das die Schneid-Klemm-Kontakte der Kontaktelemente einsteckbar sind, wobei der Schneid-Klemm-Kontakt und der Gabelkontakt zueinander verdreht angeordnet sind und mindestens eine Unterkante des Schneid-Klemm-Kontaktes sich am Kunststoffgehäuse abstützt, so dass die Kontaktelemente bei auftretenden Anschaltkräften auf die Schneid-Klemm-Kontakte verliersicher in dem Kunststoffgehäuse gehalten werden, wobei das Kunststoffgehäuse mindestens einen kammerförmigen Bereich umfasst und die Gabelkontakte in Längsrichtung von dem Kunststoffgehäuse vollständig aufgenommen sind, wobei in dem kammerförmigen Bereich an den Innenseiten Rippen angeordnet sind, die Führungen für die Gabelkontakte definieren, wobei die Kontaktbereiche der Gabelkontakte über die Rippen hervorstehen und die Rippen im vorderen Bereich abgeschrägt sind. Das Gehäuse ist dabei zweistückig ausgebildet, wobei die Gehäuseteile miteinander verrastet sind.From DE 102 57 308 B3 a connector for printed circuit boards is known, comprising a number of contact elements, wherein the contact elements each have two terminal sides, wherein one terminal side as insulation displacement contact for connecting wires and the other terminal side as a fork contact for contacting formed by pads on a circuit board, and a plastic housing into which the insulation displacement contacts of the contact elements are inserted, wherein the insulation displacement contact and the fork contact are arranged rotated to each other and at least one lower edge of the insulation displacement contact itself supported on the plastic housing, so that the contact elements are held captive in occurring Anschaltkräften on the insulation displacement contacts in the plastic housing, wherein the plastic housing comprises at least one chamber-shaped area and the fork contacts in the longitudinal direction of the plastic housing completely absorbed are arranged, wherein in the chamber-shaped region on the inner sides ribs which define guides for the fork contacts, wherein the contact areas of the fork contacts protrude over the ribs and the ribs are chamfered in the front region.

Der Erfindung liegt das technische Problem zugrunde, einen gattungsgemäßen Leiterplattensteckverbinder einfacher im Aufbau zu gestalten. Die Lösung des technischen Problems ergibt sich durch den Gegenstand mit den Merkmalen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The invention is based on the technical problem of making a generic printed circuit board connector easier to build. The solution of the technical problem results from the subject matter with the features of claim 1. Further advantageous embodiments of the invention will become apparent from the dependent claims.
Hierzu umfasst der Leiterplattensteckverbinder ein Gehäuse und eine Anzahl von Kontaktelementen, wobei jedes Kontaktelement einen Kontakt zum Anschließen von Adern und einen Kontakt zum Verbinden mit einer Leiterplatte umfasst, wobei das Gehäuse einteilig ausgebildet ist, wobei die Kontaktelemente verliersicher in dem Gehäuse verrastet sind. Hierdurch ergibt sich ein einfacher und kompakter Aufbau des Steckverbinders, da das Gehäuse beispielsweise in einem Verfahrensschritt in Spritzgusstechnik hergestellt werden kann. Hierdurch entfallen notwendige räumliche Vorhaltungen für eine Verrastung oder ähnliches am Gehäuse.For this purpose, the circuit board connector comprises a housing and a number of contact elements, wherein each contact element comprises a contact for connecting wires and a contact for connection to a printed circuit board, wherein the housing is integrally formed, wherein the contact elements are captively locked in the housing. This results in a simple and compact construction of the connector, since the housing can be made for example in a process step in injection molding. This eliminates necessary spatial Vorhaltungen for a latch or the like on the housing.
In einer bevorzugten Ausführungsform weist das Gehäuse an der Oberseite und der Unterseite Schlitze auf, in die Verdickungen der Kontaktelemente eingreifen. Da das Gehäuse aus Kunststoff hergestellt ist, weist dieses eine gewisse Federwirkung auf, so dass beim Einschieben der Kontaktelemente diese wenig belastet werden, sondern den Kunststoff des Gehäuses wegbiegen, bis die Verdickungen in den Schlitzen einrasten. Anstelle der Schlitze kann das Gehäuse auch Vorsprünge aufweisen, hinter die die Kontaktelemente beim Einschieben einrasten.In a preferred embodiment, the housing on the top and bottom underside slots, engage in the thickening of the contact elements. Since the housing is made of plastic, this has a certain spring action, so that when inserting the contact elements they are little charged, but bend away the plastic of the housing until the thickening engage in the slots. Instead of the slots, the housing may also have projections behind which engage the contact elements during insertion.
Vorzugsweise sind die Verdickungen am Kontakt zum Verbinden der Leiterplatte angeordnet. Bei einer Ausbildung mit Vorsprüngen sind diese vorzugsweise derart angeordnet, dass der Kontakt zum Anschließen der Adern hinter den Vorsprung rastet.Preferably, the thickenings are arranged on the contact for connecting the printed circuit board. In an embodiment with projections, these are preferably arranged such that the contact snaps behind the projection for connecting the wires.
In einer weiteren bevorzugten Ausführungsform ist der Kontakt zum Anschließen der Adern als Schneid-Klemm-Kontakt und/oder der Kontakt zum Verbinden der Leiterplatte als Gabelkontakt ausgebildet. In einer weiteren bevorzugten Ausführungsform ist der Schneid-Klemm- Kontakt um 45° zum Gabelkontakt gedreht, wobei die Verdrehung um die Längsachse des Kontaktelements erfolgt.In a further preferred embodiment, the contact for connecting the wires as insulation displacement contact and / or the contact for connecting the circuit board is designed as a fork contact. In a further preferred embodiment, the insulation displacement contact is rotated by 45 ° to the fork contact, wherein the rotation takes place about the longitudinal axis of the contact element.
In einer weiteren bevorzugten Ausführungsform sind an den Seitenflächen des Gehäuses Verbindungselemente angeordnet.In a further preferred embodiment, connecting elements are arranged on the side surfaces of the housing.
In einer weiteren bevorzugten Ausführungsform sind an den Verbindungselementen Seitenteile angeordnet, die weiter vorzugsweise eine Kabelführung und/oder eine Schnittstelle zum Verbinden mit einem Modulgehäuse aufweisen. Die Seitenteile können dabei je nach Anwendung unterschiedlich ausgebildet werden. Prinzipiell ist es auch möglich, an den Verbindungselementen weitere Gehäuse mit Kontaktelementen anzubinden, so dass die Möglichkeit eines modular erweiterbaren Leiterplattensteckverbinders geschaffen wird. Weiter ist es möglich, dass die Seitenteile mit der Schnittstelle und/oder der Kabelführung einstückig mit dem Gehäuse ausgebildet sind. Dies ist beispielsweise dann vorteilhaft, wenn die Flexibilität hinsichtlich Schnittstelle und/oder Kabelführung nicht benötigt wird, da dann der komplette Leiterplattensteckverbinder nur aus einem einzigen Kunststoffteil mit den Kontaktelementen besteht.In a further preferred embodiment, side parts are arranged on the connecting elements, which further preferably have a cable guide and / or an interface for connecting to a module housing. The side parts can be designed differently depending on the application. In principle, it is also possible to connect to the connecting elements further housing with contact elements, so that the possibility of a modular expandable PCB connector is created. Further, it is possible that the side parts are formed integrally with the housing with the interface and / or the cable guide. This is for example advantageous if the flexibility in terms of interface and / or cable management is not needed, since then the complete PCB connector consists only of a single plastic part with the contact elements.
In einer weiteren bevorzugten Ausführungsform ist die Schnittstelle zum Verbinden mit einem Modulgehäuse auf den Außenseiten der Seitenteile angeordnet.In a further preferred embodiment, the interface for connecting to a module housing is arranged on the outer sides of the side parts.
In einer weiteren bevorzugten Ausführungsform umfasst die Schnittstelle ein rampenförmiges Element, über und unter dem jeweils ein Rastelement angeordnet ist, wobei die Rastelemente flacher als die höchste Erhebung des rampenförmigen Elementes sind. Hierdurch bildet die höchste Erhebung des rampenförmigen Elementes einen definierten Druckpunkt, der beim Einsetzen in ein Modulgehäuse übersteht, so dass durch Druck auf die rampenförmigen Elemente die Schnittstellen nach innen gedrückt werden und die Rastelemente entrasten.In a further preferred embodiment, the interface comprises a ramp-shaped element, above and below which in each case a latching element is arranged, wherein the latching elements are flatter than the highest elevation of the ramp-shaped element. As a result, the highest elevation of the ramp-shaped element forms a defined pressure point, which protrudes when inserted into a module housing, so that by pressing the ramp-shaped elements, the interfaces are pressed inward and detent the locking elements.
In einer weiteren bevorzugten Ausführungsform sind die Verbindungselemente an den Seitenflächen des Gehäuses als Bohrung mit seitlichem Schlitz ausgebildet, wobei die Breite des Schlitzes kleiner als der Durchmesser der Bohrung ist.In a further preferred embodiment, the connecting elements are formed on the side surfaces of the housing as a bore with a lateral slot, wherein the width of the slot is smaller than the diameter of the bore.
In diesem Fall sind die korrespondierenden Verbindungselemente an den Seitenteilen als Zylinderstifte ausgebildet, die einen größeren kreisförmigen Kopf aufweisen. Zum Verbinden wird dann der Kopf durch die Bohrung gesteckt und anschließend der Zylinderstift im Schlitz verschoben, so dass es zu einer Art Verriegelung über das Kopfteil kommt. Prinzipiell sind aber auch andere Ausführungsformen für die Verbindungselemente denkbar, beispielsweise einfache Löcher, in die Zapfen gesteckt werden.In this case, the corresponding connecting elements are formed on the side parts as cylindrical pins, which have a larger circular head. To connect the head is then inserted through the hole and then moved the cylinder pin in the slot, so that it comes to a kind of locking on the headboard. In principle, however, other embodiments for the connecting elements are conceivable, for example, simple holes are inserted into the pins.
In einer weiteren bevorzugten Ausführungsform ist auf der Oberseite des Gehäuses eine Blende angeordnet, die senkrecht zur Oberseite steht. Die Blende dient primär als mechanischer Schutz für die Elemente auf der Leiterplatte.In a further preferred embodiment, a diaphragm is arranged on the upper side of the housing, which is perpendicular to the upper side. The bezel serves primarily as mechanical protection for the elements on the circuit board.
In einer weiteren bevorzugten Ausführungsform ist an den Seitenflächen des Gehäuses jeweils ein stiftförmiges Element angeordnet, wobei die stiftförmigen Elemente die Drehlager eines Schilderrahmens bilden. Das stiftförmige Element weist dabei vorzugsweise einen polygonen Querschnitt auf, vorzugsweise eines Sechseckes. Hierdurch entsteht eine Rastung zwischen Schilderrahmen und stiftförmigem Element, so dass der Schilderrahmen selbständig in einer hochgeklappten Stellung verbleibt. Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Die Fig. zeigen:In a further preferred embodiment, in each case a pin-shaped element is arranged on the side surfaces of the housing, wherein the pin-shaped elements form the pivot bearing of a sign frame. The pin-shaped element preferably has a polygonal cross section, preferably a hexagon. This creates a detent between the sign frame and pin-shaped element, so that the sign frame remains automatically in a folded-up position. The invention will be explained in more detail below with reference to a preferred embodiment. The figures show:

Der Leiterplattensteckverbinder 1 umfasst ein einteiliges Gehäuse 2 aus Kunststoff, eine Anzahl von Kontaktelementen 3 sowie zwei Seitenteile 4, 5. Das Gehäuse 2 ist im Innern mit nicht dargestellten Führungen ausgebildet, in denen die Kontaktelemente definiert geführt werden. Das Gehäuse 2 ist von der Tiefe derart ausgebildet, dass die Kontaktelemente 3 vollständig aufgenommen werden (siehe auch Fig. 8). Die Kontaktelemente 3 werden dazu von der unteren, offenen Stirnseite 6 in das Gehäuse 2 geschoben. An der oberen Stirnseite des Gehäuses 2 sind Dome 7 angeordnet, zwischen denen die Kontaktelemente 3 liegen. Auf einer Oberseite 8 des Gehäuses 2 ist eine Blende 31 angeordnet, die sich nahezu über die volle Breite des Gehäuses 2 erstreckt und senkrecht zur Oberseite 8 angeordnet ist. Auf der Oberseite 8 und einer Unterseite 10 (siehe Fig. 3) des Gehäuses 2 sind Schlitze 9 in das Gehäuse 2 eingearbeitet. Die Anzahl der Schlitze 9 in der Oberseite 8 bzw. Unterseite 10 entspricht der Anzahl der Kontaktelemente 3. Im dargestellten Beispiel dient das Gehäuse 2 zur Aufnahme von zweiunddreißig Kontaktelementen 3. Die Schlitze 9 in der Oberseite 8 sind dabei fluchtend zu den Schlitzen 9 in der Unterseite 10. An den Seitenflächen 11 des Gehäuses 2 sind Bohrungen 12 mit einem seitlichen Schlitz 13. Dabei ist die Breite des Schlitzes 13 etwas kleiner als der Durchmesser der Bohrung 12. Weiter sind an den Seitenflächen 11 bzw. den Außenseiten der beiden letzten Dome 7 stiftförmige Elemente 14 angeordnet, die einen sechseckigen Querschnitt aufweisen und als Drehlager eines nicht dargestellten Schilderrahmens dienen. Die Seitenteile 4, 5 weisen jeweils einen laschenförmigen Grundkörper 15 auf. An den Innenseiten der laschenförmigen Grundkörper 15 sind jeweils zwei stiftförmige Elemente 16 mit einem breiteren, kreisförmigen Kopfteil 17 angeordnet. Zum Verbinden der Seitenteile 4, 5 mit dem Gehäuse 2 werden die Kopfteile 17 in die Bohrung 12 gesteckt und anschließend das Seitenteil 4, 5 in Richtung der Dome 7 verschoben, wobei die stiftförmigen Elemente 16 im Schlitz 13 entlanglaufen. Das dahinterliegende Kopfteil 17, das breiter als der Schlitz 13 ist, verhindert dann, dass das Seitenteil 4, 5 abgezogen werden kann. Die Seitenteile 4, 5 weisen weiterhin eine Kabelführung 18 auf, deren Geometrie an die Bedürfnisse vor Ort angepasst werden kann. So kann der Leiterplattensteckverbinder 1 durch Verwendung verschiedener Seitenteile 4, 5 optimal an die Gegebenheiten angepasst werden. An den Außenseiten des laschenförmigen Grundkörpers 15 ist ein rampenförmiges Element 19 angeordnet, das sich bis an eine der Kabelführung 18 entgegengesetzten Stirnseite 20 des laschenförmigen Grundkörpers 15 erstreckt. Oberhalb und unterhalb des rampenförmigen Elementes 19 ist jeweils ein Rastelement 21 angeordnet, das im dargestellten Beispiel quaderförmig ausgebildet ist. Dabei ist das Rastelement 21 flacher als die höchste Erhebung 22 des rampenförmigen Elementes 19 und weiter vorzugsweise auch nicht höher als irgendeine Stelle des rampenförmigen Elementes 19.The printed circuit board connector 1 comprises a one-piece housing 2 made of plastic, a number of contact elements 3 and two side parts 4, 5. The housing 2 is formed in the interior with guides, not shown, in which the contact elements are guided defined. The housing 2 is formed from the depth such that the contact elements 3 are completely received (see also Fig. 8). The contact elements 3 are pushed from the lower, open end 6 into the housing 2. At the upper end side of the housing 2 are Dome 7 arranged between which the contact elements 3 are located. On a top 8 of the housing 2, a diaphragm 31 is arranged, which extends almost over the full width of the housing 2 and is arranged perpendicular to the top 8. On the upper side 8 and a lower side 10 (see FIG. 3) of the housing 2, slots 9 are incorporated in the housing 2. The number of slots 9 in the top 8 and bottom 10 corresponds to the number of contact elements 3. In the example shown, the housing 2 serves to receive thirty-two contact elements 3. The slots 9 in the top 8 are aligned with the slots 9 in the Bottom 10. At the side surfaces 11 of the housing 2 are bores 12 with a lateral slot 13. The width of the slot 13 is slightly smaller than the diameter of the bore 12. Next are on the side surfaces 11 and the outer sides of the last two dome. 7 arranged pin-shaped elements 14 which have a hexagonal cross-section and serve as a pivot bearing of a sign frame, not shown. The side parts 4, 5 each have a tab-shaped main body 15. On the inner sides of the tab-shaped base body 15 two pin-shaped elements 16 are each arranged with a wider, circular head portion 17. To connect the side parts 4, 5 with the housing 2, the head parts 17 are inserted into the bore 12 and then the side part 4, 5 moved in the direction of the dome 7, wherein the pin-shaped elements 16 run along in the slot 13. The underlying head part 17, which is wider than the slot 13, then prevents the side part 4, 5 can be removed. The side parts 4, 5 also have a cable guide 18, the geometry of which can be adapted to local needs. Thus, the printed circuit board connector 1 can be optimally adapted to the circumstances by using different side parts 4, 5. On the outer sides of the tab-shaped main body 15, a ramp-shaped element 19 is arranged, which extends to one of the cable guide 18 opposite end face 20 of the tab-shaped base body 15. Above and below the ramp-shaped Element 19 each have a latching element 21 is arranged, which is cuboid in the example shown. In this case, the latching element 21 is flatter than the highest elevation 22 of the ramp-shaped element 19 and further preferably not higher than any point of the ramp-shaped element 19th
Anhand der Fig. 4 bis 7 soll nun das Kontaktelement 3 näher erläutert werden. Das einstückige Kontaktelement 3 umfasst einen Schneid-Klemm- Kontakt 23 zum Anschließen von Adern und einen Gabelkontakt 24 zum Verbinden mit einer Leiterplatte. Dabei kontaktieren Kontaktbereiche 25 des Gabelkontaktes 24 metallisierte Pads auf der Leiterplatte. In Längsrichtung L sind der Gabelkontakt 24 und der Schneid-Klemm- Kontakt 23 um 45° zueinander verdreht, was am besten in Fig. 6 zu erkennen ist. Hierzu weist das Kontaktelement 3 Einschnitte 26 auf, so dass ein biegsamer Steg 27 entsteht. An den Außenseiten 28 des Gabelkontaktes 24 weist dieser Verdickungen 29 auf, die in Höhe der Kontaktbereiche 25 liegen und sich bis zur Stirnseite 30 des Gabelkontaktes 24 erstrecken. Beim Einschieben des Kontaktelementes 3 in das Gehäuse 2 rutschen die Verdickungen 29 in die Schlitze 9 der Oberseite 8 und Unterseite 10, so dass die Kontaktelemente 3 verliersicher in dem Gehäuse 2 verrastet sind. Dieser verrastete Zustand ist am besten in Fig. 8 zu erkennen. With reference to FIGS. 4 to 7, the contact element 3 will now be explained in more detail. The one-piece contact element 3 comprises a insulation displacement contact 23 for connecting wires and a fork contact 24 for connection to a printed circuit board. Contact areas 25 of the fork contact 24 contact metallized pads on the circuit board. In the longitudinal direction L of the fork contact 24 and the insulation displacement contact 23 are rotated by 45 ° to each other, which is best seen in Fig. 6. For this purpose, the contact element 3 cuts 26, so that a flexible web 27 is formed. On the outer sides 28 of the fork contact 24, this thickening 29, which lie at the level of the contact areas 25 and extend to the end face 30 of the fork contact 24. When inserting the contact element 3 in the housing 2, the thickenings 29 slip into the slots 9 of the top 8 and bottom 10, so that the contact elements 3 are captively locked in the housing 2. This locked state is best seen in Fig. 8.
