Description

Die vorliegende Erfindung bezieht sich auf einen Steckverbinder nach dem Oberbegriff des Anspruchs 1.The present invention relates to a connector according to the preamble of claim 1.

Ein aus der DE 297 04 161 U1 bekannter Steckerverbinder ist geradlinig ausgebildet und an seinem leiterplattenseitigen Anschlussende mit einem dieses umgebenden Kragen als Wegbegrenzungselement versehen. Dieser bekannte Steckverbinder wird in Richtung seiner und der Längserstreckung der Kontaktelemente und damit senkrecht zur Ebene der Leiterplatte mit dieser verbunden. Diese Art der Verbindung eines Steckverbinders mit einer Leiterplatte benötigt viel Raum nicht nur für die Verbindung an sich, sondern auch für den Vorgang des Steckens oberhalb der Ebene der Leiterplatte. Dieser Raum bzw. Platz ist in vielen Fällen nicht gegeben bzw. vorhanden.One from the DE 297 04 161 U1 Known plug connector is formed in a straight line and provided at its circuit board side terminal end with a surrounding collar as Wegbegrenzungselement. This known connector is connected in the direction of its and the longitudinal extension of the contact elements and thus perpendicular to the circuit board level with this. This type of connection of a connector with a PCB requires a lot of space not only for the connection itself, but also for the process of plugging above the level of the circuit board. This space or space is not given or available in many cases.

Ein Steckverbinder der eingangs genannten Art ist aus der US-A-4 702 707 bekannt geworden, bei dem das Adapterteil mehrere zweite Anschlussenden aufweist, die im Querschnitt rechteckförmig sind und durchkontaktierte Bohrungen durchdringen und an ihren herausragenden Enden mit der durchkontaktierten Bohrung verlötet sind.A connector of the type mentioned is from the US-A-4,702,707 have become known in which the adapter part has a plurality of second terminal ends, which are rectangular in cross-section and penetrate through holes and are soldered at their protruding ends with the plated-through hole.

Aus der EP-A1-0 546 884 ist ein Steckverbinder bekannt geworden, bei dem die zweiten Anschlussenden Teile von einzelnen durchgehenden Kontaktelementen sind und an ihren im Querschnitt rechteckförmigen Kontaktteilen nach zwei Seiten ballig geformt sind. Diese Anschlussenden werden in durchkontaktierte Bohrungen unter Reibschluss gedrückt. Ein separater Montageschenkel begrenzt den Einsteckweg.From the EP-A1-0 546 884 is a connector has become known in which the second terminal ends are parts of individual continuous contact elements and are spherically shaped at their rectangular in cross-section contact parts on two sides. These connection ends are pressed into plated-through holes under frictional engagement. A separate mounting leg limits the insertion path.

Aufgabe der vorliegenden Erfindung ist es, einen Steckverbinder der eingangs genannten Art zu schaffen, der zur steckbaren Verbindung mit einer Leiterplatte weniger Raum oberhalb der Leiterplatte beansprucht und der dennoch zu einer sicheren Verbindung mit der Leiterplatte führt.Object of the present invention is to provide a connector of the type mentioned, which claimed for pluggable connection to a circuit board less space above the circuit board and yet leads to a secure connection to the circuit board.

Zur Lösung dieser Aufgabe sind bei einem Steckverbinder der eingangs genannten Art die im Anspruch 1 angegebenen Merkmale vorgesehen.To solve this problem, the features specified in claim 1 are provided in a connector of the type mentioned.

Durch die erfindungsgemäßen Maßnahmen ist erreicht, dass die zum Verbinden notwendige Zuführbewegung des Steckverbinders zur Leiterplatte in einer Richtung parallel und wenig über der Oberfläche der Leiterplatte erfolgen kann, so dass der Steckverbinder weniger weit über die Oberfläche der Leiterplatte hinausragt. Das am Gehäuse oder der Leiterplatte vorgesehene Wegbegrenzungselement führt zu einer sicheren Verbindung und zu kleinen Abständen zwischen Gehäuse des Steckverbinders und der Leiterplatte.By means of the measures according to the invention, it is achieved that the supply movement of the connector to the printed circuit board necessary for the connection can be parallel in one direction and slightly above the surface of the printed circuit board, so that the connector protrudes less far beyond the surface of the printed circuit board. The provided on the housing or the printed circuit board Wegbegrenzungselement leads to a secure connection and to small distances between the housing of the connector and the circuit board.

In bevorzugter Ausgestaltung vorliegender Erfindung ist gemäß den Merkmalen des Anspruchs 2 als Wegbegrenzungselement ein Anlagewinkel am Gehäuse vorgesehen, der sich auf die betreffende Oberfläche der Leiterplatte legt und damit eine genaue und sichere Kontaktierung gewährleistet, sowie auf den Steckverbinder einwirkende Kräfte, die beim Einstecken des Steckers auftreten, aufnehmen kann. Außerdem kann das Stecken des Steckverbinders bzw. dessen Kontaktelemente in die Bohrungen der Leiterplatte ohne ein die Verbindung möglicherweise nachteilig beeinflußendes Kippmoment auf den Steckverbinder erfolgen.In a preferred embodiment of the present invention, a contact angle is provided on the housing according to the features of claim 2 as Wegbegrenzungselement, which lays down on the relevant surface of the circuit board and thus ensures accurate and secure contact, as well as acting on the connector forces when inserting the plug occur, can record. In addition, the plugging of the connector or its contact elements in the holes of the circuit board without a connection possibly adversely affecting tipping moment can be made to the connector.

Eine weitere Verbesserung und Vereinfachung der Montage bzw. steckbaren Verbindung des Steckverbinders auf einer Leiterplatte bei gleichzeitig möglichst einfacher Gestaltung eines entsprechenden Montagewerkzeugs wird dann erreicht, wenn die Merkmale gemäß Anspruch 3 vorgesehen sind.A further improvement and simplification of the assembly or pluggable connection of the connector on a printed circuit board with the simplest possible design of a corresponding assembly tool is achieved when the features are provided according to claim 3.

Das Kontaktelement kann gemäß dem Merkmal des Anspruchs 4 einstückig sein, was bis zu einem bestimmten minimalen Abstand zwischen Steckverbinder und Leiterplatte möglich ist, da dann das Kontaktelement noch durch einfaches Biegen entsprechend winklig gestaltet werden kann.The contact element may be in one piece according to the feature of claim 4, which is possible up to a certain minimum distance between the connector and circuit board, since then the contact element still by simply bending can be designed according to an angle.

Wird dieser genannte Abstand zwischen Steckverbinder und Leiterplattenoberfläche unterschritten, so ist es zweckmäßig, gemäß den Merkmalen des Anspruchs 5, das Kontaktelement mehrteilig auszubilden. Dadurch sind noch geringere Bauhöhen, als dies beim Biegen der Kontaktelemente möglich ist, erzielbar. Dies ist von besonderer Bedeutung bei den zunehmend höheren Packungsdichten in elektronischen Bauteilen. Außerdem ermöglicht dies, unterschiedliche Bauhöhen zu realisieren, da das steckerseitige Anschlussteil gleich bleibt und nur die Bauhöhe bzw. -länge des leiterplattenseitigen Anschlussendes verändert wird. Ein weiterer Vorteil besteht darin, unterschiedliche Oberflächen der Anschlussenden zu realisieren, so dass sie den jeweiligen Funktionen und Anforderungen angepasst werden können. Dies gilt auch für eine entsprechende optimale Materialauswahl an den jeweiligen Anschlussenden. Schließlich ist eine vielfältige Kombination je nach der notwendigen Formgestaltung der Anschlussenden möglich.If this mentioned distance between the connector and the circuit board surface is undershot, then it is expedient, according to the features of claim 5, to form the contact element in several parts. As a result, even lower heights, as this is possible when bending the contact elements, can be achieved. This is of particular importance in the increasingly higher packing densities in electronic components. In addition, this makes it possible to realize different heights, since the plug-side connector remains the same and only the height or length of the circuit board side terminal end is changed. Another advantage is to realize different surfaces of the terminal ends, so that they can be adapted to the respective functions and requirements. This also applies to a corresponding optimal material selection at the respective terminal ends. Finally, a diverse combination depending on the necessary shape of the terminal ends is possible.

Der Angriffsbereich gemäß den Merkmalen des Anspruchs 3 kann in vielfältiger Weise verwirklicht sein, bspw. durch eine Querbohrung mit oder ohne Stift, durch eine umlaufende Nut mit oder ohne Ring, durch einen kegelförmigen Bund am Umfang, durch Flächen parallel zur Leiterplattenoberfläche u.dgl.The attack area according to the features of claim 3 can be realized in many ways, for example. By a transverse bore with or without pin, by a circumferential groove with or without ring, by a conical collar on Circumference, by surfaces parallel to the circuit board surface and the like.

Vorteilhafte Ausgestaltungen der mehrteiligen Ausbildung des bzw. der Kontaktelemente ergeben sich aus den Merkmalen eines oder mehrerer der Ansprüche 6 bis 12.Advantageous embodiments of the multi-part design of the contact element or elements result from the features of one or more of claims 6 to 12.

Der in den Figuren 1 und 2 dargestellte Einrichtung 10 besitzt einen Steckverbinder 15, der mit in mehreren Ausführungsbeispielen dargestellten ein- oder mehrteiligen Kontaktelementen 11, 11', 11'', 12 bzw. 13 versehen ist und der einenends mit der Verbindung einer Leiterplatte 14 und andernends derjenigen mit einem nicht dargestellten externen Stecker dient. Der Steckverbinder 15 erstreckt sich in einer zur Oberfläche 16 der Leiterplatte 14 parallelen Richtung und ist über die abgewinkelt ausgebildeten Kontaktelemente 11, 11', 11'', 12 bzw. 13 mit der Leiterplatte 14 verbindbar.The device 10 shown in Figures 1 and 2 has a connector 15 which is provided with one or more parts shown in one or more parts contact elements 11, 11 ', 11' ', 12 and 13 and the one end with the connection of a printed circuit board 14th and on the other hand, the one with an external connector, not shown, is used. The connector 15 extends in a direction parallel to the surface 16 of the printed circuit board 14 and is connected via the angled formed contact elements 11, 11 ', 11' ', 12 and 13 to the circuit board 14 connectable.

Die mehreren, beim Ausführungsbeispiel drei nebeneinander angeordneten gleichartigen Kontaktelemente 11, 11', 11'', 12 bzw. 13 des Steckverbinders 15 besitzen horizontal, d.h. parallel zur Leiterplattenoberfläche 16 ausgerichtete bzw. verlaufende steckerseitige Anschlussenden 18 und mittels Adapter 20, 20', 20'', 30 bzw. 40 um 90° winklig, d.h. senkrecht zu diesen verlaufende leiterplattenseitige Anschlussenden 19, die über eine Pressfitverbindung in durchkontaktierte Bohrungen 17 der Leiterplatte 14 steckbar und lösbar passen.The several, in the embodiment three juxtaposed similar contact elements 11, 11 ', 11'', 12th or 13 of the connector 15 have horizontally, ie parallel to the circuit board surface 16 aligned or extending plug-side terminal ends 18 and by means of adapters 20, 20 ', 20'', 30 and 40 at 90 ° angled, ie perpendicular to these extending board-side terminal ends 19th , which plug and detachably fit over a Pressfitverbindung in plated-through holes 17 of the circuit board 14.

Wie den Figuren 1 und 2 zu entnehmen ist, besitzt der Steckverbinder 15 ein Gehäuse 21, in welchem die steckerseitigen Anschlussenden 18 der Kontaktelemente 11, 11', 11'', 12 bzw. 13 in axialer Richtung und verdrehsicher gehalten sind. Die steckerseitigen Anschlussenden 18, die stiftartig oder buchsenartig ausgebildet sein können, sind hierbei im einen Gehäuseteil 25 festhaltenden, nicht dargestellten Formstoffkörper fixiert. Das Gehäuse 21 ist in einem Rücksprung 22 der Leiterplatte 14 angeordnet und mittels zweier Winkel 23 in Bohrungen 24 der Leiterplatte 14 steckbar verriegelbar gehalten. Die beiden Winkel 23, die an Seitenflanschen 26 des Gehäuses 21 befestigt sind, dienen als Wegbegrenzungselemente beim Einsetzen der leiterplattenseitigen Anschlussenden 19 der Kontaktelemente 11, 11', 11'', 12 bzw. 13 in die durchkontaktierten Bohrungen 17 der Leiterplatte 14, damit eine der Figur 2 entsprechende Pressfitpassung an der korrekten örtlichen Stelle des leiterplattenseitigen Anschlussendes 19 gewährleistet ist. Die Verbindung von Steckverbinder 15 und Leiterplatte 14 erfolgt in einer senkrecht zur Leiterplattenoberfläche 16 gerichteten Bewegung zum Einstecken der leiterplattenseitigen Anschlussenden 19 in die durchkontaktierte Bohrungen 17 bis zum Auftreffen bzw. Einsetzen der betreffenden Enden der beiden winkelförmigen Wegbegrenzungselemente 23. Nach dem Aufsetzen kann ein Niet o.ä. zur festen Verbindung zwischen Leiterplatte 14 und Wegbegrenzungselement 23 durch deren korrespondierende Bohrungen gebracht werden. Figur 2 zeigt hierbei, dass in eingesetztem Zustand die Bauhöhe des Steckverbinders 15 über der Leiterplattenoberfläche 16 aufgrund des Ausnutzens der Leiterplattendicke und des notwendigen Überstandes zu anderen Seite hin sehr gering ist.As can be seen from Figures 1 and 2, the connector 15 has a housing 21 in which the plug-side terminal ends 18 of the contact elements 11, 11 ', 11'', 12 and 13 are held in the axial direction and against rotation. The plug-side terminal ends 18, which may be pin-like or bush-like, are in this case fixed in a housing part 25 retaining, not shown molding material. The housing 21 is arranged in a recess 22 of the printed circuit board 14 and held by means of two angle 23 in holes 24 of the circuit board 14 plug lockable. The two angles 23, which are attached to side flanges 26 of the housing 21, serve as Wegbegrenzungselemente when inserting the circuit board side terminal ends 19 of the contact elements 11, 11 ', 11'', 12 and 13 in the plated-through holes 17 of the circuit board 14, thus a Figure 2 corresponding Pressfitpassung to the correct local Location of the circuit board side terminal end 19 is ensured. The connection of connector 15 and printed circuit board 14 takes place in a direction perpendicular to the circuit board surface 16 movement for inserting the circuit board side terminal ends 19 in the plated-through holes 17 to the impact or insertion of the respective ends of the two angular Wegbegrenzungselemente 23. After placing a rivet o .ae. be brought to the fixed connection between the printed circuit board 14 and Wegbegrenzungselement 23 through the corresponding holes. FIG. 2 shows in this case that in the inserted state, the height of the connector 15 above the circuit board surface 16 is very low due to the utilization of the printed circuit board thickness and the necessary projection to the other side.

Figur 3 zeigt das in Figur 2 beim Steckverbinder 15 verwendete Kontaktelement 11 in auseinandergezogener Darstellung. Das Kontaktelement 11 ist zweiteilig, d.h. bei diesem Ausführungsbeispiel ist das leiterplattenseitige Anschlussende 19 mit dem Adapter 20 einstückig und das steckerseitige Anschlussende 18 ein davon getrenntes mit dem Adapter 20 verbindbares Bauelement. Hierzu besitzt der Adapter 20 eine zur axialen Richtung des leiterplattenseitigen Anschlussendes 19 senkrechte Querbohrung 29, in die ein Stift 31 in Spiel- oder Presspassung ggf. unter zusätzlicher Vernietung, Verlötung oder vergleichbarer mechanischer elektrischer Verbindung einsteckbar ist. Das steckerseitige Anschlussende 18 besitzt etwa längsmittig zwei im Abstand voneinander angeordnete Ringbunde 32, über die dieses Bauelement im genannten im Gehäuseteil 25 gehaltenen Formstoffkörper axial gesichert eingebaut ist. Die Verdrehsicherung kann, wie in Figur 6 gezeigt, als Abflachung 50 an einem der Ringbunde 32 ausgeführt sein, so dass sich das Kontaktelement 13 nicht im Formstoffkörper drehen kann.FIG. 3 shows the contact element 11 used in the connector 2 in FIG. 2 in an exploded view. The contact element 11 is in two parts, ie, in this embodiment, the circuit board-side terminal end 19 is integral with the adapter 20 and the plug-side terminal end 18 is a separate connected to the adapter 20 component. For this purpose, the adapter 20 has a transverse to the axial direction of the printed circuit board side terminal end 19 transverse bore 29 into which a pin 31 in game or Press fit possibly with additional riveting, soldering or comparable mechanical electrical connection can be inserted. The plug-side terminal end 18 has approximately longitudinally two spaced-apart annular collars 32, over which this component is mounted axially secured in the said molded part body held in the housing part 25. The rotation can, as shown in Figure 6, be designed as a flattening 50 on one of the annular collar 32, so that the contact element 13 can not rotate in the molding material body.

Wie bei allen Kontaktelementen 11, 11', 11'', 12 und 13 ist das leiterplattenseitige Anschlussende 19 im Einsteckbereich zweifach geschlitzt, so dass sich mehrere, hier vier radial elastisch bewegbare Finger 33 ergeben. Außenseitig sind diese Finger 33 am vorderen freien Ende mit einer Fase, am rückwärtigen Ende mit einer Taille 35 und mittig mit einem Kontaktbauch 44 versehen.
