Description

Die Erfindung bezieht sich auf eine Leiterplattensteckbuchse mit einem auf einer Leiterplatte festlegbaren, im Querschnitt rechteckigen Metallbuchsengehäuse und einem in das Buchsengehäuse eingesetzten, einen entsprechend rechteckigen Querschnitt besitzenden Isolierkörper, der vier in einer Ebene nebeneinanderliegende, als Kontaktfedern ausgebildete Signalkontakte aufweist, die beim Stecken des Bussteckers mit den in diesem vorgesehenen vier nebeneinanderliegenden Gegenkontakten zusammenwirken und den elektrischen Kontakt herstellen und die über nach unten gerichtete Anschlußenden mit den Kontaktstellen der Leiterplatte verbindbar sind.The invention relates to a printed circuit board socket with a fixable on a circuit board, in Cross section rectangular metal socket housing and one in it Inserted socket housing, a correspondingly rectangular Cross-section insulating body, the four side by side in a plane, has signal contacts designed as contact springs, which at Insert the bus connector with the four side by side provided in it Counter contacts interact and the electrical Make contact and face downward Connection ends can be connected to the contact points on the circuit board are.

Bei einer bekannten Leiterplattensteckbuchse dieser Art (DE 296 02 268 U1) liegt das Steckbuchsengehäuse mit seiner unteren Gehäusewand auf der Leiterplatte unmittelbar auf. Dabei sind sowohl die Schirmkontakte des Steckbuchsengehäuses als auch die vier nebeneinanderliegenden Signalkontakte als sich rechtwinklig zur unteren Gehäusewand erstreckende Einlötstifte ausgebildet, die in Lötkontaktbohrungen der zugehörigen Leiterplatte eingeführt und darin nach dem Lötwellenverfahren von unten verlötet werden.In a known circuit board socket of this type (DE 296 02 268 U1) is the socket housing with its lower Housing wall on the circuit board immediately. there are both the shield contacts of the socket housing and the four adjacent signal contacts as being rectangular Soldering pins extending to the lower housing wall, those in solder contact holes on the associated circuit board introduced and from below according to the solder wave process to be soldered.

Diese Vorgangsweise ist mit dem Nachteil verbunden, daß neben dem allgemein üblichen SMT-Reflowverfahren, mit dem alle sonstigen Bauteile auf der Leiterplatte verlötet werden, ein weiteres Lötverfahren, nämlich das Lötwellenverfahren erforderlich ist.This procedure has the disadvantage that in addition to the common SMT reflow process, with which all other components are soldered to the circuit board further soldering process, namely the solder wave process required is.

An dieser Stelle ist zu erwähnen, daß ein umfangreicher druckschriftlicher Stand der Technik existiert, der sich mit dem Festlegen der Anschlüsse von Steckverbindern an den Leiterbahnen befaßt, so z.B. mit Hilfe der Reflow-Technik, allerdings unter kostspieligem, zeitaufwendigem Einsatz von zusätzlichen Schraub- oder Nietverbindungen zur mechanischen Entlastung der Lötstellen (Druckschrift "Elektrotechnik" 24/27.11.1987, S. 136).At this point it should be mentioned that an extensive printed state of the art exists, which deals with the Define the connections of connectors on the conductor tracks concerned, e.g. with the help of the reflow technique, however under costly, time-consuming use of additional screw or riveted joints to mechanically relieve the solder joints (Publication "Electrical engineering" 24 / 27.11.1987, p. 136).

Ferner ist das Verbinden von Kontakten von Steckerleisten mit Leiterplatten bekannt (DE 43 07 134 A1), indem die Kontaktenden in Bohrungen der Leiterplatten eingeführt und darin verlötet werden. Auch diese Methode ist arbeits- und kostenintensiv.Furthermore, the connection of contacts of power strips known with printed circuit boards (DE 43 07 134 A1) by the Contact ends inserted into holes in the circuit board and in it to be soldered. This method is also labor and cost intensive.

Zu erwähnen ist ferner die bekannte Festlegung eines mehrpoligen Steckverbinders auf einer Leiterplatte unter Verwendung von dem Verbinder Halt gebenden, metallischen L-förmigen Traglaschen, die dem Festlöten an der Leiterplatte dienen und mit einer Durchgangsbohrung zur Erhöhung der Fixierkräfte versehen sind (JP 1-197 978 A). Also to be mentioned is the known definition of a using multi-pin connector on a printed circuit board metallic L-shaped from the connector Carrying tabs that are used for soldering to the circuit board and provided with a through hole to increase the fixing forces are (JP 1-197 978 A).

Weiterhin bekannt ist eine Leiterplattensteckbuchse der eingangs genannten Art, bei der im Bodenbereich des Buchsengehäuses eine Aussparung vorgesehen ist, durch die hindurch sich die nach unten gerichteten und dann abgewinkelten Anschlußenden der Signalkontakte des in das Buchsengehäuse eingesetzten Isolierkörpers zu den zugehörigen Leiterbahnen der Leiterplatte hin erstrecken, mit denen sie aufgrund ihrer Ausbildung als SMT-Kontakte verlötbar sind (US-A-5 591 050). Das im Verhältnis zur Breite nur eine geringe Tiefe besitzende Metallbuchsengehäuse dieser Leiterplattensteckbuchse weist einen sich über eine vordere Begrenzungswand nach vorn erstreckenden quaderförmigen Gehäusebereich auf, der der Aufnahme des entsprechend quaderförmig gestalteten, von einer Vielzahl von Bohrungen für die Kontakte durchsetzten Isolierkörpereinsatzes des eigentlichen Isolierkörpers dient. Dieser Isolierkörper liegt quer hinter der Begrenzungswand und läuft mit beiden Enden, die über den zentralen Bereich des die Bohrungen für die Kontakte aufweisenden Isolierkörpers vorstehen, jeweils in einen Verstärkungsbereich aus, der über Stabilisierungsnuten durch ihnen vorgelagerte untere Haltelaschen des Metallbuchsengehäuses erfaßt und durch Verlötung dieser Laschen mit der Leiterplatte verbindbar sind. Diese bekannte Ausführung ist mit dem Nachteil verbunden, daß die in relativ großem Abstand voneinander beiderseits der eigentlichen Leiterplattensteckbuchse befindlichen Haltelaschen zusätzlich ziemlich viel Platz oberhalb der Leiterplatte beanspruchen, überdies aber mittels der Laschen eine besonders sorgfältige Festlegung sicherstellen müssen, da im Falle eines Lösens auch nur einer der beiden Haltelaschen aufgrund der dann wirksamen großen Hebelkräfte die Gefahr einer vollständigen Freigabe der Leiterplattensteckbuchse von der Leiterplatte besonders groß ist.Also known is a printed circuit board socket of the type mentioned at the beginning, in which a recess is provided in the bottom area of the socket housing through which the downward and then angled connection ends of the Signal contacts of the insulating body inserted into the socket housing to the associated one Conductor tracks of the circuit board extend with which they are due to their training are solderable as SMT contacts (US-A-5 591 050). In relation to the width only this socket connector has a shallow metal socket housing has a cuboid extending forward over a front boundary wall Housing area on which the receiving of the corresponding cuboid, from a variety of holes for the contacts insulated insert the actual insulating body is used. This insulating body lies transversely behind the boundary wall and runs with both ends over the central area of the holes project for the insulating body having contacts, each in a reinforcement area from, the lower retaining tabs in front of them via stabilizing grooves of the metal socket housing and by soldering these tabs to the PCB are connectable. This known embodiment has the disadvantage that that the at a relatively large distance from each other on both sides of the actual PCB socket holding tabs also a lot of space above the circuit board claim, but also a particularly careful determination by means of the tabs must be ensured, since in the event of loosening, only one of the two retaining tabs due to the then high leverage, the risk of a complete Release of the circuit board socket from the circuit board is particularly large.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine wesentlich einfachere und dennoch sichere Festlegung und Verbindung von USB-Leiterplattensteckbuchsen auf den Leiterplatten bei dennoch nur einem Lötprozeß zu ermöglichen. The invention is therefore based on the object, a much simpler and nevertheless secure fixing and connection of USB circuit board sockets on the To enable printed circuit boards with only one soldering process.

Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst,
daß das der Aufnahme des Isolierkörpers mit den vier nach dem USB-Konzept standardisierten Signalkontakten dienende Buchsengehäuse bodenseitig einen Abstand zur Leiterplatte sicherstellende Stütz- und Verbindungsbereiche aufweist, von denen zumindest einige jeweils durch eine von der unteren Vorderkante des Buchsengehäuses ausgehende, um etwa 180° nach unten und rückwärts umgebogene Fixierlasche gebildet sind und über diese Fixierlaschen mit der Leiterplatte im Reflowverfahren verlötbar sind. that the socket housing serving to accommodate the insulating body with the four signal contacts standardized according to the USB concept has a spacing from the printed circuit board on the bottom side to ensure support and connection areas, of which at least some each through a starting from the lower front edge of the socket housing, by about 180 ° Fixing tabs bent over at the bottom and back are formed and can be soldered to the printed circuit board in the reflow process via these fixing tabs. According to the invention, this object is essentially achieved by According to the invention, this object is essentially achieved by
that the receptacle of the insulating body with the four signal contacts standardized according to the USB concept serving on the bottom side has a distance to the printed circuit board supporting and connecting areas, at least some of which extend from the lower front edge of the socket housing by about 180 ° are formed below and backwards bent fixing tab and can be soldered to the circuit board in the reflow process via these fixing tabs. that the receptacle of the insulating body with the four signal contacts standardized according to the USB concept serving on the bottom side has a distance to the printed circuit board supporting and connecting areas, at least some of which extend from the lower front edge of the socket Housing by about 180 ° are formed below and backwards bent fixing tab and can be soldered to the circuit board in the reflow process via these fixing tabs.

Aufgrund dieser Ausbildung ist sichergestellt, daß die beim Steckvorgang auf das Metallbuchsengehäuse wirkenden Steckkräfte praktisch unmittelbar unter dessen Mündungsbereich auf die Leiterplatte übertragen werden, ohne daß hierfür ein größerer Platzbedarf erforderlich wäre.This training ensures that the mating process on the Metal socket housing acting forces practically immediately below its mouth area can be transferred to the circuit board without requiring a larger space for this would be required.

Dabei hat es sich als besonders vorteilhaft erwiesen, wenn jede Lasche eine ausgestanzte Bohrung mit einem am Bohrungsrand angeformten, der Leiterplatte zugewandten Kragen aufweist, der in eine Öffnung der Leiterplatte eingreift. Durch diesen Kragen werden horizontale Steckkräfte auf besonders einfache Weise formschlüssig zur Leiterplatte aufgenommen.It has proven to be particularly advantageous if each tab has a punched out Hole with one at the edge of the hole molded collar facing the circuit board, which engages in an opening of the circuit board. By this collar becomes horizontal insertion forces on particularly simple Form positively added to the circuit board.

Eine besonders gleichmäßige Auflage der Anschlußenden auf der Leiterplatte wird in weiterer Ausbildung der Erfindung dadurch sichergestellt, daß der Isolierkörper an seiner Unterseite einen in die Aussparung des Buchsengehäuses mit vorzugsweise fünf angeformten Stegen hineinragenden verstärkten Körperbereich aufweist und daß die Anschlußenden der Kontaktfedern zwischen diesen Stegen vorgesehen sind.A particularly even support of the connection ends on the circuit board in a further embodiment of the invention thereby ensuring that the insulating body on its underside one in the recess of the socket housing with preferably five molded-in webs protruding reinforced body area and that the terminal ends of the contact springs are provided between these webs.

Eine genaue Positionierung der Anschlußenden in bezug auf die Leiterplatte ergibt sich, wenn der Isolierkörper mit mindestens zwei quer abstehehenden Führungszapfen versehen ist, die in ihnen zugeordnete Ausnehmungen der Leiterplatten eingreifen. Precise positioning of the connector ends with respect on the circuit board results if the insulator with at least two transversely projecting guide pins are provided, the recesses in the circuit boards assigned in them engage.
