Description

Beschreibungdescription

Die Erfindung betrifft eine Leiterkartensteckverbindung zur elektrischen Kontaktierung für zwei parallel gegenüberliegende, beabstandete Leiterplatten mit oberflächenmontierbaren Verbindungselementen zum gegenseitigen Ineinandergreifen, die eine Steckseite und eine Lötseite aufweisen.The invention relates to a printed circuit board connector for making electrical contact for two parallel, spaced printed circuit boards with surface-mountable interconnecting elements for mutual engagement having a mating side and a soldering side.

Eine derartige Verbindung wird benötigt, um zwei parallel ausgerichtete Leiterplatten elektrisch mittels einer Steckverbindung zu kontaktieren, wobei die Kontaktierung an beliebigen Stellen von Leiterplatte zu Leiterplatte erfolgen soll und wobei Signale im GHz-Bereich störungssicher zu übertragen sind.Such a connection is required to electrically contact two parallel aligned printed circuit boards by means of a plug-in connection, wherein the contacting is to take place at arbitrary locations from printed circuit board to printed circuit board and wherein signals in the GHz range are to be transmitted without interference.

Stand der TechnikState of the art

Leiterkartensteckverbinder für eine "board-to-board" Verbindung sind als kreisförmig ausgeführte Einzelsteckverbinder oder als länglich ausgeführte Reihensteckverbinder mit mehrfach nebeneinander angeordneten Kontakten verfügbar.
Wobei Steckverbindungen mit Einzelkontakten überwiegend als Drehteil ausgeführt sind, deren Herstellung relativ kostenintensiv ist.Circuit board connectors for a "board-to-board" connection are available as circular single connectors or as elongate series connectors with multiple side-by-side contacts.
Wherein plug-in connections with individual contacts are predominantly designed as a turned part, the production of which is relatively expensive.

Aus der US 7,118,383 B2 ist ein Koaxial-Steckverbinder für eine Verbindung von zwei Leiterplatten bekannt, bei dem zwei oberflächenmontierbare, rohrförmige Steckerkörper ineinander gesteckt werden, wobei ein stiftförmiger, zentrischer Kontakt des einen Steckerkörpers in einen U-förmigen Gegenkontakt des anderen Steckerkörpers eingreift.From the US 7,118,383 B2 is a coaxial connector for a connection of two printed circuit boards is known in which two surface-mountable tubular plug body are inserted into one another, wherein a pin-shaped, centric contact of a plug body engages in a U-shaped mating contact of the other plug body.

Aufgabenstellungtask

Der Erfindung liegt daher die Aufgabe zugrunde, eine Leiterplattensteckverbindung der eingangs genannten Art dahingehend auszubilden, dass mittels eines kompakten Verbindungselementes, eine hochfrequenzfähige, elektrische Verbindung zwischen zwei Leiterplatten auszugestalten, wobei jedes Verbindungselement oberflächenmontiert mit der Leiterplatte verbunden sein soll.The invention is therefore based on the object to form a printed circuit board connector of the type mentioned in that by means of a compact connection element to design a high-frequency, electrical connection between two circuit boards, each connection element should be surface mounted connected to the circuit board.

Diese Aufgabe wird dadurch gelöst, dass das Verbindungselement einen mehrseitigen symmetrischen, kragenförmigen Grundkörper aufweist, dass in zwei gegenüberliegenden Eckbereichen, einem ersten Eckbereich und einem zweiten Eckbereich des Grundkörpers Kerben vorgesehen sind, und dass innerhalb des Grundkörpers, in einem dritten Eckbereich zwischen den beiden Kerben, eine Kontakthalterung für mindestens einen zum Zentrum des Grundkörpers weisenden elektrischen Signalkontakt vorgesehen ist.This object is achieved in that the connecting element has a multi-sided symmetrical, collar-shaped basic body, that notches are provided in two opposite corner regions, a first corner region and a second corner region of the base body, and that within the base body, in a third corner region between the two notches , a contact holder is provided for at least one pointing to the center of the body electrical signal contact.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2-18 angegeben.Advantageous embodiments of the invention are specified in claims 2-18.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass mittels der kragenförmigen Struktur des Verbindungselementes, in dessen Innenraum ein isoliert angeordneter, elektrischer Kontakt vorgesehen ist, eine hochfrequenzdichte bis in den GHz-Bereich verwendbare Steckverbindung möglich ist.
Dabei ist das Verbindungselement vorzugsweise als quadratisches, hermaphroditisches Steckteil ausgeführt, das heißt, es ist mit einem baugleichen Steckteil steckbar.
Es sind aber auch weitere, mehrseitige, symmetrisch geformte Verbindungselemente denkbar.
Der aus nichtleitendem Material gefertigte Grundkörper des Verbindungselementes ist komplett von einem elektrisch leitenden Überzug umgeben.The advantages achieved by the invention are, in particular, that by means of the collar-shaped structure of the connecting element, in the interior of which an electrically arranged electrical contact is provided, a high-frequency up to the GHz range usable connector is possible.
In this case, the connecting element is preferably designed as a square, hermaphroditic plug-in part, that is, it can be plugged with a similar plug-in part.
But there are also more, multi-sided, symmetrically shaped fasteners conceivable.
The base body made of non-conductive material of the connecting element is completely surrounded by an electrically conductive coating.

Während im Inneren des Grundkörpers eine elektrisch isolierende Kontakthalterung mit einem darin eingehakten elektrischen Kontakt angeordnet ist, das als separates Bauteil mit entsprechenden gegenseitig wirkenden vorgesehenen Rastmitteln im Grundkörper einsetzbar ist.
Wobei Grundkörper und Kontakthalterung aus thermischen Erwägungen vorteilhafterweise aus dem gleichen isolierenden Material gefertigt sind. Entsprechend ist eine Anordnung der Lötflächen auf den Leiterplatten vorgesehen, so dass der elektrisch leitende Überzug des Verbindungselementes und der Signalkontakt entsprechend getrennten Lötflächen kontaktiert.
In einer Variante kann vorgesehen sein, dass der Grundkörper des Verbindungselementes an wesentlichen Teilen, vorzugsweise im Innenbereich, mit einem elektrisch leitenden Überzug versehen.
Wobei die Kontakthalterung - ohne elektrisch leitenden Überzug - direkt in den Grundkörper eingeformt ist.
Lediglich der innere elektrische Kontakt ist als zusätzliches Bauteil, geformt als Stanzbiegeteil, erforderlich.While inside the body an electrically insulating contact holder is arranged with an electrical contact hooked therein, which can be used as a separate component with corresponding mutually acting locking means provided in the body.
Wherein body and contact holder for thermal considerations are advantageously made of the same insulating material. Accordingly, an arrangement of the solder pads is provided on the circuit boards, so that the electrically conductive coating of the connecting element and the signal contact contacted according to separate pads.
In a variant, it can be provided that the base body of the connecting element is provided with an electrically conductive coating on essential parts, preferably on the inside.
The contact holder - without electrically conductive coating - is molded directly into the main body.
Only the internal electrical contact is required as an additional component, formed as a stamped and bent part.

Zur Erzielung einer hochfrequenzfähigen, abgeschirmten Signalübertragung ist es sinnvoll, die beiden Verbindungselemente ineinandersteckbar auszuführen, so dass optimalerweise eine Art Labyrinthdichtung gebildet wird. Dazu ist der kragenförmige Grundkörper an zwei gegenüberliegenden Eckbereichen mit Kerben versehen, die ein gegenseitiges Ineinanderstecken der beiden identischenverbindungselemente erlauben. Wobei beim Steckvorgang ein Verbindungselement axial um 180° gedreht - seitlich leicht versetzt gegenüber dem anderen - angeordnet ist.To achieve a high-frequency, shielded signal transmission, it makes sense to make the two connecting elements nestable, so that optimally a kind of labyrinth seal is formed. For this purpose, the collar-shaped base body is provided at two opposite corner areas with notches, which allow a mutual nesting of the two identical connecting elements. Wherein during insertion a connecting element is rotated axially by 180 ° - laterally slightly offset from the other - is arranged.

Weiterhin ist steckseitig in dem durch die beiden Kerben eingeschlossenen Eckbereich auf der Kontakthalterung, die den elektrischen Kontakt aufnimmt vorteilhafterweise eine Ansaugfläche vorgesehen, mittels der eine Automatenbestückung des Verbindungselementes auf einer Leiterplatte erfolgen kann.Furthermore, on the plug side, in the corner region enclosed by the two notches, on the contact holder, which receives the electrical contact, a suction surface is advantageously provided, by means of which automatic assembly of the connecting element on a printed circuit board can take place.

Wie bereits oben angedeutet, ist mindestens der Innenbereich, bis auf den isolierenden Bereich des elektrischen Kontaktes, mittels MID-Technik elektrisch leitend beschichtet. Das betrifft auch die beiden Kerben und den mit trichterförmigen Schrägen umlaufenden Kragenrand, sowie den zur Leiterplatte weisenden Kragenrand, in dem vorteilhafterweise Bohrungen vorgesehen sind, die auf das zwischen dem Verbindungselement und der Leiterplatte eingebrachte Lötmittel eine kapillare Wirkung ausüben und eine sichere Lötung bewirken.As already indicated above, at least the inner region, except for the insulating region of the electrical contact, is coated in an electrically conductive manner by means of MID technology. This also applies to the two notches and the circumferential collar edge with funnel-shaped bevels, as well as to the circuit board facing collar edge in which advantageously holes are provided which exert on the introduced between the connecting element and the circuit board solder a capillary action and cause secure soldering.

Der umlaufende, steckseitige Kragenrad weist vorteilhafterweise Schrägen auf, die ein leichteres "Einfangen" zweier zu steckender Verbindungselemente begünstigen, wobei Fehlausrichtungen in der Z-Achse, horizontal gedreht von bis zu +/- 10° tolerierbar für ein Verbindungspaar sind.
Während noch bei einer vertikal geneigten Z-Achse von 7° ein "Einfangen" des Gegensteckers realisierbar ist.
In der Z-Achse, also dem Höhenabstand zwischen zwei Leiterplatten, ist eine Toleranz für den gesteckten Zustand von +/- 0,75 mm vorgesehen.
Da die Verbindungselemente als Kunststoffspritzteile gefertigt werden, ist ein gestufter Abstandsbereich zwischen zwei Leiterplatten von ca. 6 - 30 mm vorgesehen.
Vorzugsweise sind Abstände von 6,7 mm, 19 mm, 28,7 mm vorgesehen. Obwohl als Signalkontakt vorgesehen, ist bei entsprechender Dimensionierung des Verbindungselementes mit dem Signalkontakt durchaus eine Variante als so genannter Power-Kontakt denkbar, wobei auch eine Variante ohne den innenliegenden Signalkontakt realisierbar ist.
Weiterhin ist vorgesehen, Mehrfachkontakte innerhalb des Grundkörpers anzuordnen, die hierbei vorteilhafterweise als hermaphroditische Kontakte ausgebildet sind und einen geraden und einen S-förmigen Kontaktschenkel ausweisen, so dass beim Kontaktieren von zwei entsprechend ausgerüsteten Verbindungselementen, jeweils zwei unterschiedlich geformte Kontaktschenkel miteinander kontaktieren.The circumferential, plug-side collar wheel advantageously has bevels, which favor easier "capture" of two to be connected fasteners, with misalignments in the Z-axis, horizontally rotated by up to +/- 10 ° are tolerable for a connection pair.
While still with a vertically inclined Z-axis of 7 °, a "catching" of the mating connector is feasible.
In the Z-axis, ie the height distance between two printed circuit boards, a tolerance for the inserted state of +/- 0.75 mm is provided.
Since the connecting elements are manufactured as plastic injection molded parts, a stepped distance range between two printed circuit boards of approximately 6 to 30 mm is provided.
Preferably, distances of 6.7 mm, 19 mm, 28.7 mm are provided. Although provided as a signal contact, with appropriate dimensioning of the connecting element with the signal contact quite a variant as a so-called power contact conceivable, with a variant without the internal signal contact can be realized.
Furthermore, it is provided to arrange multiple contacts within the body, which are advantageously designed as hermaphroditic contacts and identify a straight and an S-shaped contact legs, so that when contacting two appropriately equipped connecting elements, two differently shaped contact legs contact each other.

In der Fig.1 ist in einer isometrischen Darstellung ein einstückiges, kragenförmiges Verbindungselement mit Sicht auf den Steckbereich gezeigt.
Das Verbindungselement 1 ist als quadratischer, kragenförmiger Grundkörper 10 geformt, wobei in zwei gegenüberliegenden Eckbereichen 14, 16 jeweils eine senkrecht zum Kragen 11 eingeformte Kerbe 15, 17 vorgesehen ist.
Der gesamte Grundkörper 10 ist mit einer elektrisch leitenden Beschichtung überzogen.In the Fig.1 is shown in an isometric view of a one-piece, collar-shaped connecting element with a view of the plug-in area.
The connecting element 1 is formed as a square, collar-shaped base body 10, wherein in each case one perpendicular to the collar 11 formed notch 15, 17 is provided in two opposite corner regions 14, respectively.
The entire base body 10 is coated with an electrically conductive coating.

Die Kerbe 15, 17 hat etwa eine Öffnungsweite, die der Kragendicke entspricht und in dieser Darstellung eine Tiefe, die etwa der halben Höhe der gesamten Kragenhöhe entspricht.
In dem von den beiden Kerben 15, 17 eingeschlossenen Eckbereich18, ist innerhalb des Grundkörpers 10 eine aus isolierendem Material geformte Kontakthalterung 30 eingefügt, die zur Aufnahme eines elektrischen Signalkontaktes 40, hier als Einzelkontakt ausgeführt, vorgesehen ist.
Die Kontakthalterung 30 weist zur Steckseite eine hier dreieckförmige Ansaugfläche 31 auf, die als so genannter pick-and-place Punkt ein maschinengesteuertes Platzieren des Verbindungselementes auf einer Leiterplatte erlaubt.
Der Kragen 11 weist einen steckseitigen Kragenrand 12 mit beidseitig nach innen und außen und umlaufend Abschrägungen 20, 21 auf, womit ein leichteres Ineinanderschieben von zwei identischen Verbindungselementen begünstigt wird.The notch 15, 17 has approximately an opening width which corresponds to the collar thickness and in this illustration a depth which corresponds approximately to half the height of the entire collar height.
In the corner area 18 enclosed by the two notches 15, 17, a contact holder 30 formed of insulating material is inserted inside the main body 10 and is provided for receiving an electrical signal contact 40, here as a single contact.
The contact holder 30 has the plug-in side here a triangular suction surface 31, which allows a so-called pick-and-place point a machine-controlled placement of the connecting element on a circuit board.
The collar 11 has a plug-side collar edge 12 on both sides inwardly and outwardly and circumferentially bevels 20, 21, whereby a easier telescoping of two identical connecting elements is favored.

An den Eckbereichen 14, 16 sind weiterhin nach außen wirkende Anreihungselemente angeformt, die als Nut 26 und Feder 27 ausgebildet sind. Dabei ist die Feder 27 tonnenförmig mit sich verjüngenden Außenbereichen geformt, so dass bei einer Aneinanderreihung mehrerer Verbindungselemente, zunächst ein leichtes Einfügen der Feder in die Nut erfolgt, bis der dickere Mittelbereich der Nut-Feder-Kombination eine formschlüssige Verbindung ergibt. Dabei ist anzumerken, dass die Nut 26 ebenfalls eine tonnenförmige Längsform mit sich erweiternden Außenbereichen aufweist.At the corner regions 14, 16 further outwardly acting Anreihungselemente are formed, which are formed as a groove 26 and spring 27. In this case, the spring 27 is barrel-shaped with tapered outer areas, so that when a juxtaposition of a plurality of connecting elements, first a slight insertion of the spring into the groove until the thicker middle region of the tongue and groove combination results in a positive connection. It should be noted that the groove 26 also has a barrel-shaped longitudinal shape with expanding outer areas.

Die Fig. 2 zeigt den quadratischen Grundkörper 10 des Verbindungselementes aus Sicht der Lötseite.
Signifikant sind zunächst die beiden T-förmigen Ausnehmungen 19 in den beiden Kragenseiten 11, die den Eckbereich 18 bilden. Hier wird die Kontakthalterung 30 mit entsprechend vorspringenden Rastschienen 32 eingeschoben und gehalten.The Fig. 2 shows the square base body 10 of the connecting element from the perspective of the solder side.
Significant are first the two T-shaped recesses 19 in the two collar sides 11, which form the corner region 18. Here, the contact holder 30 is inserted and held with corresponding projecting locking rails 32.

Weiterhin weist der Eckbereich eine Nut 24 auf, in die ein am Signalkontakt angeformter Lötfuß 42 zum Verlöten auf einem Lötpad auf einer Leiterplatte einsetzbar ist.
Auf dem lötseitigen Kragenrand 13 sind hier zwei Fixierstifte 22 angeformt, die zur Polarisierung und Halterung auf einer Leiterplatte dienen, bis beim Lötvorgang das Lötmittel den Kragenrand und die darin vorgesehenen Bohrungen 23, in die es aufgrund kapillarer Kräfte aufsteigt, endgültig fixiert hat.Furthermore, the corner region has a groove 24 into which a soldering foot 42 formed on the signal contact can be used for soldering to a solder pad on a printed circuit board.
On the solder side collar edge 13 two fixing pins 22 are here formed, which serve for polarization and mounting on a circuit board until the soldering process, the solder collar edge and the holes provided therein 23, in which it rises due to capillary forces, finally fixed.

Das obere glatte Dreieck ist der Ansaugbereich 31 zur maschinengesteuerten Plazierung des gesamten Verbindungselementes auf einer Leiterplatte vorgesehen.
In der Mitte ist eine säulenähnliche Struktur erkennbar, wobei in der Ausnehmung zwischen den beiden Säulen hier oben ein Durchbruch 33 im unteren Bereich eine Vertiefung 34 und am Fuß eine Tasche 35 ausgebildet ist. Während mit den senkrechten, vorspringen Rastschienen 32 die Fixierung der Kontakthalterung in den T-förmigen Ausnehmungen19 im Grundkörper 10 gewährleistet ist.The Fig. 3a, 3b, 3c show in several representations, the contact holder 30 in which the signal contact 40 is used.
Being in the Fig. 3a and 3b an upright position and the Fig. 3c a reverse position is displayed.
The floor plan is formed according to the insertion in the corner region 18 as a triangular foot 36 with a height corresponding to the wall height of the main body 10 reaches a maximum up to the inner bevel 20.
The upper smooth triangle is the suction region 31 for machine-controlled placement of the entire connecting element on a printed circuit board.
In the middle of a column-like structure can be seen, in the recess between the two columns up here an opening 33 in the lower part of a recess 34 and at the foot of a pocket 35 is formed. While with the vertical, projecting locking rails 32, the fixation of the contact holder in the T-shaped recesses 19 in the base body 10 is ensured.

Der in Fig. 4a, 4b gezeigte Signalkontakt 40 weist letztlich eine U-Form auf, mit einem nach außen gebogenen Kontaktbereich 41 und einem flachen Lötfuß 42.
An drei Positionen, im oberen Schenkelende, im unteren Schenkelende sowie unterhalb des gebogenen Kontaktbereiches sind jeweils dreiseitig freistehende Rasthaken 43 herausgebogen. Mittels dieser Rasthaken wird der Signalkontakt in dem Durchbruch 33, in der Vertiefung 34 und in der Tasche 35 verrastet.The in Fig. 4a, 4b Signal contact 40 shown has finally a U-shape, with an outwardly bent contact portion 41 and a flat soldering foot 42nd
At three positions, in the upper leg end, in the lower leg end and below the curved contact area each free-standing three-sided locking hooks 43 are bent out. By means of these latching hook the signal contact in the opening 33, in the recess 34 and in the pocket 35 is locked.

Hierbei ist auch vorgesehen, die isolierende Kontakthalterung 30 für den Signalkontakt 40 direkt in den Grundkörper einzuformen. Die elektrische Beschichtung ist nicht sonderlich gezeigt.The Fig. 5 shows a variant 1 'of the connecting element 1 in which only the inner walls and running at different angles plug-side collar edge 12 are internally and externally provided with an electrically conductive coating to achieve an optimal high-frequency shielding effect at a complete mating. In this case, it is also provided to mold the insulating contact holder 30 for the signal contact 40 directly into the main body. The electrical coating is not particularly shown.

In der Fig. 6a sind zwei Verbindungselemente 1 oder 1' dargestellt, die jeweils auf einer Leiterplatte 3, 5 montiert, miteinander kontaktieren. Dabei ist das hier obere Verbindungselement mit der Leiterplatte 5 um 180° gedreht. Durch die diagonal eingeformten Kerben15, 17 im Kragen 11 können die beiden Grundkörper, leicht versetzt, komplett ineinander gesteckt werden, wobei zunächst die abschirmende Beschichtung der Kragenwände kontaktieren bis etwas später die beiden innenliegenden Signal kontakte miteinander kontaktieren.In the Fig. 6a are two connecting elements 1 or 1 'shown, each mounted on a circuit board 3, 5, contact each other.
