Abstract

The flat plug (1) includes a contact blade (2) and a fixture and connection zone aligned longitudinally with the contact blade. The flat plug is free-standing and electrically connectable and fixed on a substrate. In the fixture and connection zone (3) of the flat plug, at least two contact zones (5,6) are provided for a solderless insertion connection. The flat plug has lateral extensions (7,8) between the fixture- and connection- zones and the contact-blade on both oppositely facing flat sides. The extensions pass laterally beyond the width of the contact blade (2), and form a shoulder (9) at the upper face facing away from the substrate (4) for mounting an insertion tool and a insertion abutment (10) on the lower face turned towards the substrate (4).

Description

Die Erfindung betrifft einen Flachstecker für elektrische Steckverbindungen, mit einem Kontaktmesser und einem in Längsrichtung fluchtend zu dem Kontaktmesser verlaufenden Befestigungs- und Anschlußbereich, in dem der Flachstecker freistehend an einer Unterlage befestigbar und elektrisch anschließbar ist.The invention relates to a tab for electrical connectors, with a contact blade and extending in the longitudinal direction of the contact blade attachment and connection area in which the tab is freestanding fastened to a pad and electrically connected.

Bei elektrischen Steckverbindungen bestehen Flachsteck-Kontaktorgane häufig aus einem flachen, geraden Kontaktmesser, das in einem Befestigungs- und Anschlußbereich freistehend an einer Unterlage, zum Beispiel an einer unter anderem auch als Kontaktträger dienenden Leiterplatte, befestigt wird. Solche Flachsteck-Kontaktorgane werden allgemein und daher auch im folgenden als Flachstecker (DIN 46 244) bezeichnet. Flachstecker hat man bisher durch Löten an einer Leiterplatte befestigt und angeschlossen. Dabei werden die Flachstecker von Hand mit Vorrichtungen gesteckt und anschließend gelötet. Das Stecken und Löten der Flachstecker ist somit sehr handarbeitsintensiv und damit auch teuer. Außerdem ist das Löten im Zusammenhang mit der ständig steigenden Komplexität der Leiterplatten ein immer größer werdendes Qualitätsrisiko. Aus diesem Grunde ist auch eine stetige Prozeß- und Qualitätskontrolle erforderlich.In electrical connectors are flat plug contact members often made of a flat, straight contact blade, which is freestanding in a mounting and connection area on a base, for example, on a serving as a contact carrier circuit board, among other things. Such tabs contact elements are generally and therefore also referred to below as a flat plug (DIN 46 244). Flat plug has been attached and connected by soldering to a circuit board. The tabs are plugged by hand with devices and then soldered. The plugging and soldering the tabs is therefore very manual labor intensive and therefore expensive. In addition, soldering in connection with the ever increasing complexity of printed circuit boards is an ever-increasing quality risk. For this reason, a constant process and quality control is required.

Es sind Flachstecker in von einem Kontaktmesser abgewinkelter Ausführung sowie in gerader Ausführung gebräuchlich, die zum Einlöten in Leiterplatten in der Kontaktzone mit zwei Lötanschlußstiften ausgebildet und durch Einstecken in die Leiterplattenlöcher und Anlöten freistehend an der Leiterplatte befestigt werden. Ferner ist aus der EP 0 717 468 A2 eine aus Feder- und Messerleiste bestehende Steckverbindung bekannt, bei der die Messerkontakte als abgewinkelte Flachsteck-Kontaktelemente ausgebildet sind, die in einem Isolierkörper der Messerleiste, also nicht freistehend in einem Gehäuse aufgenommen und in dem vom Kontaktmesser abgewinkelten Befestigungs- und Anschlußbereich mit Einpreßstiften versehen sind.There are tabs in angled from a contact blade design and in straight form, which are designed for soldering in printed circuit boards in the contact zone with two Lötanschlußstiften and attached by plugging in the PCB holes and brazing freestanding on the circuit board. Furthermore, from the EP 0 717 468 A2 an existing spring and male connector plug connection known in which the blade contacts are designed as angled tabs contact elements, which are not freestanding housed in an insulating body of the male connector in a housing and provided in the angled by the contact blade mounting and connection area with Einpreßstiften ,

Aus der US-A-3846741 ist in Übereinstimmung mit dem Oberbegriff des Anspruchs 1 ein Flachstecker bekannt, bei dem die beiden Kontaktzonen durch nach außen gewölbte Bereiche eines auf sich selbst zurückgefalteten Blechstücks gebildet sind. Beide Kontaktzonen werden in ein Loch einer Leiterplatte eingesteckt. Durch die Auswölbung wird eine Federkraft bereitgestellt, die den Flachstecker in dem Loch der Leiterplatte hält und sicheren elektrischen Kontakt mit der leitenden Innenwand des Lochs in der Leiterplatte garantiert.From the US-A-3846741 is in accordance with the preamble of claim 1, a tab known, in which the two contact zones are formed by outwardly curved portions of a folded back on itself sheet metal piece. Both contact zones are plugged into a hole in a circuit board. The bulge provides a spring force that holds the tab in the hole in the circuit board and guarantees secure electrical contact with the conductive inner wall of the hole in the circuit board.

Ein aus US 4 688 866 bekannter Flachstecker weist zwischen einem Kontaktmesser und einem Befestigungs- und Anschlussbereich an beiden gegenüberliegenden Flachseiten über die Breite des Kontaktsmessers hinausragende seitliche Ansätze auf, bei denen es sich um Reste eines eine Vielzahl Flachstecker bandförmig verbindende Verbindungsstege handelt. An der einer Leiterplatte zugewandten Seite weist der Flachstecker zwischen Anschlussbeinen aus der Flachsteckerebene seitlich herausgebogene Abstützelemente auf, um bei seitlich auf den Flachstecker einwirkenden Kräften eine gegen Kippen des Flachsteckers wirkende Abstützung zu bilden.On off US 4,688,866 Known flat plug has between a contact blade and a mounting and connecting portion on both opposite flat sides over the width of the contact blade protruding lateral lugs, which are remnants of a plurality of tabs band-shaped connecting connecting webs. On the side facing a printed circuit board, the flat plug between connecting legs of the flat plug level laterally bent out support elements to form a laterally acting on the tabs forces acting against tilting of the tab plug support.

Der Erfindung liegt die Aufgabe zugrunde, für einen geraden und freistehenden Flachstecker der eingangs genannten Art eine einfache und zuverlässige Befestigung und Kontaktierung an einer Unterlage zu schaffen.The invention has for its object to provide for a straight and free-standing tab of the type mentioned a simple and reliable attachment and contacting a pad.

Diese Aufgabe wird mit einem Flachstecker gemäß Patentanspruch 1.This object is achieved with a tab according to claim 1.

Ein derartiger gerader Flachstecker kann in einfacher Weise mit seinen Kontaktzonen durch Einpressen in Löcher einer Unterlage, zum Beispiel eines Kontaktträgers in Form einer Leiterplatte, eingebracht werden und ist dann als freistehender Kontakt an der Unterlage befestigt. Die für eine lötfreie Einpreßverbindung ausgelegten Kontaktzonen führen im in die Löcher der Unterlage, z. B. in die metallisierten Bohrungen einer Leiterplatte eingepreßten Zustand zu einem sicheren und dauerhaften elektrischen Anschluß an der Unterlage. Die Befestigung und Kontaktierung eines erfindungsgemäßen Flachsteckers läßt sich daher schnell, billig und in zuverlässiger Weise realisieren.Such a straight tab can be easily introduced with its contact zones by pressing into holes in a pad, for example a contact carrier in the form of a printed circuit board, and is then attached as a free-standing contact to the pad. The designed for a solder-free press-fit connection zones lead in the holes in the pad, z. B. in the metallized holes of a circuit board pressed state to a safe and permanent electrical connection to the pad. The attachment and contacting of a tab according to the invention can therefore be realized quickly, cheaply and reliably.

Bei einem derartigen Flachstecker ist es zweckmäßig, wenn die Kontaktzonen als stiftförmige Einpreßanschlüsse ausgebildet sind.In such a tab, it is advantageous if the contact zones are formed as pin-shaped press-fit.

Im Hinblick auf die erforderlichen Haltekräfte beim Einsatz als freistehender Kontakt ohne Gehäuse ist es vorteilhaft, wenn die Kontaktzonen massiv ausgeführt sind. Grundsätzlich ist es aber auch möglich und in vielen Fällen sicher auch ausreichend, wenn die Kontaktzonen elastische Einpreßabschnitte aufweisen.With regard to the required holding forces when used as a free-standing contact without housing, it is advantageous if the contact zones are made massive. In principle, however, it is also possible and certainly sufficient in many cases when the contact zones have elastic press-in sections.

Bei derartigen Flachsteckern treten im an der Unterlage befestigten Zustand häufig über das Kontaktmesser auf die Einpreßanschlüsse und damit auf die Befestigung und den elektrischen Anschluß einwirkende Belastungen auf. Es ist daher vorteilhaft, dass bei einem erfindungsgemäßen Flachstecker der mit den seitlichen Ansätzen ausgebildete Abschnitt des Flachsteckers mit mindestens einer Ausnehmung versehen ist. Eine derartige Ausnehmung ist bei einem aus einem Blechstanzteil bestehenden Flachstecker durch eine Freistanzung gebildet und hat zum Beispiel eine Rechteckform. Die geometrische Ausführung ist jedoch nicht an die Rechteckform gebunden; es sind vielmehr unterschiedliche, in den übrigen Unteransprüchen angegebene Ausführungen für die geometrische Form einer Ausnehmung möglich. In jedem Fall bildet eine solche, im Abschnitt mit den seitlichen Ansätzen angeordnete Ausnehmung eine Sollbiegestelle, d. h. bei am Kontaktmesser z. B. quer zur Steckrichtung angreifenden Biegekräften ist das Widerstandsmoment an der von der Ausnehmung gebildeten Sollbiegestelle in Folge der Querschnittsverminderung zu gering, um die Einpreßverbindung lockern zu können. Stattdessen werden solche Biegekräfte in der Sollbiegestelle aufgenommen, was zu einer Um- bzw. Verformung des Flachsteckers führt, dessen Kontaktmesser dann aus der Steckrichtung verbogen wird. Die Einpreßverbindung wird aber nicht gelockert, d. h. die durch die Ausnehmung entstandene Sollbiegestelle bildet einen Schutz der Einpreßkontaktierung gegen Lockerung und sichert damit die Anschlußkontaktierung. Beim Richten von verbogenen Flachsteckern gewährleistet die Sollbiegestelle in Umkehrung des beschriebenen Effektes ebenfalls den Bestand des Einpreßkontaktes. Dabei hat sich durch Erprobungen bestätigt, daß die in der DIN IEC 352 geforderten Biegezyklen (= Simulation des Richtvorganges von verbogenen Steckern) sicher erreicht werden.In such tabs occur in the attached to the pad state often on the contact blade on the press-fit and thus on the attachment and the electrical connection loads acting on. It is therefore advantageous that, in the case of a flat connector according to the invention, the section of the flat connector formed with the lateral projections is provided with at least one recess. Such a recess is formed in a flat connector consisting of a sheet metal stamping part by a free punching and has, for example, a rectangular shape. However, the geometric design is not bound to the rectangular shape; it is rather different, specified in the remaining dependent claims statements for the geometric shape of a recess possible. In any case, such, arranged in the section with the lateral projections recess forms a predetermined bending point, ie at the contact blade z. B. transverse to the insertion direction acting bending forces is the moment of resistance at the predetermined bending point formed by the recess in consequence of Neck reduction too low to be able to loosen the Einpreßverbindung. Instead, such bending forces are absorbed in the predetermined bending point, which leads to a deformation or deformation of the tab, the contact blade is then bent from the plugging direction. However, the press-fit connection is not loosened, ie the resulting by the recess predetermined bending point forms a protection of Einpreßkontaktierung against loosening and thus secures the Anschlusskontaktierung. When straightening bent flat connectors, the predetermined bending point, in reversal of the described effect, also ensures the continuity of the press-fit contact. It has been confirmed by tests that the bending cycles required in DIN IEC 352 (= simulation of the straightening process of bent connectors) are reliably achieved.

Der Flachstecker 1 besteht bevorzugt aus einem Blechstanzteil und weist ein am freien Ende üblicherweise abgeschrägtes flaches Kontaktmesser 2 mit in der Längsmittelachse liegendem Rastloch 3 auf. Außerdem besitzt der Flachstecker 1 einen in Längsrichtung fluchtend zu dem Kontaktmesser 2 verlaufenden Befestigungs- und Anschlußbereich 3, in dem der somit gerade ausgebildete Flachstecker freistehend an einer Unterlage, z. B. an einer Leiterplatte 4 befestigbar und in durchkontaktierten Löchern der Leiterplatte elektrisch anschließbar ist. Hierzu sind im Befestigungs- und Anschlußbereich 3 des Flachsteckers 1 mindestens zwei für eine lötfreie Einpreßverbindung ausgelegte Kontaktzonen 5, 6 vorgesehen, welche zweckmäßigerweise als stiftförmige Einpreßanschlüsse ausgebildet sind. Die Kontaktzonen 5, 6 können massiv ausgeführt sein oder elastische Einpreßabschnitte aufweisen. Um den Flachstecker in rationeller weise mit einfachen Einpreßwerkzeugen in die Leiterplatte 4 einpressen zu können, ist der Flachstecker zwischen dem Befestigungs- und Anschlußbereich 3 und dem Kontaktmesser 2 an beiden einander gegenüberliegenden Flachseiten eines Abschnittes A mit über die Breite des Kontaktmessers 2 hinausragenden seitlichen Ansätzen 7, 8 ausgebildet. Diese ergeben an der der Unterlage 4 abgewandten Oberseite eine Schulter 9 zum Ansetzen eines Einpreßwerkzeuges und an der der Unterlage zugewandten Unterseite einen Einpreßanschlag 10. Außerdem ist der mit den seitlichen Ansätzen 7, 8 ausgebildete Abschnitt A ist mit einer Ausnehmung 11 versehen, d. h. die Ausnehmung 11 liegt außerhalb des Steck- bzw. Kontaktbereiches des Kontaktmessers 2 und in bevorzugter Weise möglichst nahe an dem Befestigungs- und Anschlußbereich 3. Die Ausnehmung 11 bietet zum Schutz der Einpreßkontaktierung gegen Lockerung sowie zur Aufrechterhaltung der Kontaktierung beim Richten von verbogenen Flachsteckern dadurch, daß in dem Abschnitt A des Flachsteckers dessen Querschnitt vorzugsweise erheblich vermindert wird, eine Sollbiegestelle, welche bei auftretenden Biegekräften ein zu geringes Widerstandsmoment besitzt, um die Einpreßkontaktierung lockern zu können und welche bei derartigen Belastungen in gewünschter Weise zu einem Verbiegen an einer bestimmten Stelle des Flachsteckers führt, ohne die Einpreßverbindung und -kontaktierung zu beeinträchtigen.The tab 1 preferably consists of a stamped sheet metal part and has a flat contact blade 2, which is usually bevelled at the free end, with a latching hole 3 lying in the longitudinal center axis. In addition, the tab 1 has a longitudinally aligned to the contact blade 2 extending mounting and connection area 3, in which the thus formed flat plug freestanding on a base, z. B. to a circuit board 4 fastened and electrically connected in plated-through holes of the circuit board. For this purpose, at least two designed for a solder-free press-in connection contact zones 5, 6 are provided in the attachment and connection area 3 of the tab 1, which are expediently designed as a pin-shaped press-fit. The contact zones 5, 6 can be solid or have elastic press-in sections. In order to press the tab in a rational manner with simple press tools in the circuit board 4, the tab between the mounting and connection area 3 and the contact blade 2 on both opposite flat sides of a section A with over the width of the contact blade 2 protruding lateral lugs. 7 , 8 trained. These result at the upper side facing away from the base 4 a shoulder 9 for applying a press tool and at the underside facing the pad a Einpreßanschlag 10. In addition, the formed with the lateral projections 7, 8 section A is provided with a recess 11, d. H. the recess 11 is located outside of the plug or contact region of the contact blade 2 and preferably as close as possible to the mounting and connecting portion 3. The recess 11 provides to protect the Einpreßkontaktierung against loosening and to maintain contact when straightening bent tabs characterized, that in the section A of the tab whose cross-section is preferably substantially reduced, a predetermined bending point, which has a low moment of resistance occurring bending forces to loosen the Einpreßkontaktierung and which at such loads in the desired manner to a bend at a certain point of the tab leads, without affecting the press-in connection and -kontaktierung.

Die Ausnehmung 11 ist bei einem aus einem Blechstanzteil bestehenden Flachstecker 1 durch eine Freistanzung gebildet und hat in bevorzugter Weise eine quer zur Steckrichtung des Flachsteckers 1 sich erstreckende Rechteckform. Hierbei reicht die Ausnehmung 11 - wie auch bei den anderen Ausführungsformen in den Figuren 2 bis 6 - in Richtung quer zur Steckrichtung des Flachsteckers 1 etwa über den Mittenabstand m der Kontaktzonen 5, 6.The recess 11 is formed in a sheet metal stamping consisting of a flat connector 1 by a free punching and preferably has a transverse to the direction of insertion of the tab 1 extending rectangular shape. In this case, the recess 11 extends - as in the other embodiments in the FIGS. 2 to 6 - In the direction transverse to the direction of insertion of the tab 1 about the center distance m of the contact zones 5, the sixth

Die Ausführungsformen in den Figuren 2 und 6 unterscheiden sich von der Ausführungsform in Figur 1 lediglich in der geometrischen Form der Ausnehmung. In Figur 2 sind in dem oben beschriebenen Sinne drei kleinere kreisförmige Ausnehmungen 11a vorgesehen, die ebenfalls eine für eine Sollbiegestelle ausreichende Querschnittsverminderung im Abschnitt A ergeben. Dies wird in Figur 3 durch eine einzige größere Ausnehmung 11b von kreisrunder Form realisiert. In Figur 4 hat die Ausnehmung 11 die Form eines sich quer zur Steckrichtung des Flachsteckers erstreckenden Langloches 11c, in Figur 5 die Form einer Ellipse 11d. Schließlich ist die Ausnehmung 11e in Figur 6 als Dreieck ausgebildet. Es sind auch Vieleckformen für die Ausnehmung denkbar. In jedem Fall wird durch die symmetrisch in Bezug auf die Längsmittelachse des Flachsteckers angeordnete Ausnehmung eine für eine Sollbiegestelle an einer bestimmten Stelle des Flachsteckers ausreichende Querschnittsverminderung erreicht.The embodiments in the Figures 2 and 6 differ from the embodiment in FIG. 1 only in the geometric shape of the recess. In FIG. 2 are provided in the sense described above, three smaller circular recesses 11a, which also give a sufficient for a predetermined bending area reduction in section A. This will be in FIG. 3 realized by a single larger recess 11b of circular shape. In FIG. 4 has the recess 11 in the form of a transverse to the direction of insertion of the tab plug extending slot 11c, in FIG. 5 the shape of an ellipse 11d. Finally, the recess 11e in FIG. 6 formed as a triangle. There are also polygonal shapes for the recess conceivable. In any case, by means of the recess arranged symmetrically with respect to the longitudinal center axis of the tab, a cross-sectional reduction sufficient for a predetermined bending point at a specific point of the tab is achieved.
