Der Erfindung liegt daher die Aufgabe zugrunde, einen Steckverbinder vorzustellen, der für die Übertragung von hochfrequenten Signalen geeignet ist, wobei mehrere elektrische Leiter, jeweils paarweise, in einer von mehreren abschirmenden Kammern eines Steckverbindergehäuses, anzuordnen sind. Wobei eine Variante als gewinkelte Version wie auch eine gerade ausgeführte Version für eine Leiterplattenmontage vorzusehen ist.The invention is therefore based on the object to present a connector which is suitable for the transmission of high-frequency signals, wherein a plurality of electrical conductors, in pairs, in one of several shielding chambers of a connector housing to arrange. Where a variant is to be provided as angled version as well as a currently running version for a circuit board assembly.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.This object is solved by the characterizing features of
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.
Bei der Erfindung handelt es sich um einen Rundsteckverbinder, der vier differenziell ausgebildete Signalleitungen in vier voneinander getrennten Kammern für eine optimale Abschirmung der vier differenziellen Signalleitungen aufnimmt.The invention relates to a circular connector which receives four differentially formed signal lines in four separate chambers for optimum shielding of the four differential signal lines.
Dabei ist vorteilhaft eine kreuzförmige Längsstruktur des Rundsteckverbinders vorgesehen, in deren jeweiligen Segmenten jeweils eine differenzielle Signalleitung - also je zwei Einzelleiter - eingebracht sind.
Dazu ist ein Kontaktträger vorgesehen, bestehend aus einem isolierenden Material, als Träger für elektrische Kontakte vorgesehen und das Schirmkreuz umfassend, in der Form, dass der Kontaktträger direkt um das Schirmkreuz herum aufgespritzt wird, auf das Schirmkreuz aufschiebbar oder mehrteilig darauf verrastbar ist.In this case, a cross-shaped longitudinal structure of the circular connector is advantageously provided, in each of whose segments a differential signal line - ie two individual conductors - are introduced.
For this purpose, a contact carrier is provided, consisting of an insulating material, provided as a support for electrical contacts and the shield cross comprising, in the form that the contact carrier is sprayed directly around the screen cross around, slidable on the screen cross or multi-part can be latched thereto.
Hier werden insgesamt acht elektrische Kontakte, entweder mit einer Buchse oder einem Stift auf ihrer Steckseite versehen, in entsprechende Aufnahmerillen vorteilhaft in den Eckbereichen des kreuzförmigen Kontaktträgers eingefügt.
Für eine Leiterplattenmontage sind die Anschlussenden um etwa 90° abgewinkelt, wobei sich unterschiedliche Längen der Kontakte ergeben, um ein kreisförmiges Anschlussgebilde auf der Leiterplatte zu erzielen.
Auf diese Anordnung wird ein isolierender Rundkörper aufgeschoben, der in seinem Steckbereich vier Teilkreissegmente aufweist, in denen jeweils zwei der elektrischen Kontakte untergebracht sind.
Damit ist vorteilhaft ein lückenlos abgeschirmter Signaltransfer möglich, zumal der isolierende Rundkörper stets von einem metallisch leitenden Gehäuse in Form eines Frontplatteneinsatzes für einen Gegenstecker oder gar eines kompletten, die Leiterplatte umgebenden elektrisch leitenden Gehäuses, innerhalb dessen der interne Steckverbinder mit einem von außen zugeführten Gegenstecker verbindbar ist.Here are a total of eight electrical contacts, either provided with a socket or a pin on its mating side, advantageously inserted into corresponding receiving grooves in the corner regions of the cross-shaped contact carrier.
For PCB mounting, the terminal ends are angled at approximately 90 °, with different lengths of contacts resulting in a circular connection formation on the PCB.
In this arrangement, an insulating round body is pushed, which has four pitch circle segments in its plug-in area, in each of which two of the electrical contacts are housed.
Thus, a fully shielded signal transfer is advantageously possible, especially since the insulating round body always connected by a metallic conductive housing in the form of a front panel insert for a mating connector or even a complete, the circuit board surrounding electrically conductive housing, within which the internal connector with an externally supplied mating connector is.
Für eine exakte Ausrichtung der Anschlussenden ist vorteilhafterweise eine Positionierhilfe vorgesehen, die an der Anschlussseite an dem Steckverbinder fixiert wird und entsprechend der Anordnung der Leiterplattenanschlüsse Bohrungen aufweist, so dass die Anschlussenden exakt auf die Leiterplattenanschlüsse ausgerichtet werden.For an exact alignment of the terminal ends, a positioning aid is advantageously provided, which is fixed to the connector side on the connector and according to the arrangement of the printed circuit board terminals has holes, so that the terminal ends are aligned exactly to the PCB connections.
Dabei ist eine gestufte Höhenverteilung innerhalb der kreisförmigen Anordnung der Bohrungen von Vorteil, so dass nicht alle Leiterplattenkontakte zur gleichen Zeit in die Positionierungshilfe einzufädeln sind.In this case, a stepped height distribution within the circular arrangement of the holes is advantageous, so that not all PCB contacts are to be threaded at the same time in the positioning aid.
Die elektrischen Kontakte sind als Drahtkontakte ausgebildet und werden in Längsrillen jeweils in entsprechenden Rillen in den vier Segmenten des Kontaktträgers eingerastet, so dass der darüber geschobene Rundkörper die Kontakte sicher aufnimmt.
Dabei sind die elektrischen Kontakte wahlweise als Stift- wie auch als Buchsenkontakt ausgebildet.
Der hier vorzugsweise dargestellte Rundsteckverbinder wird in einer geraden und einer gewinkelten Version vorgestellt und ist für eine direkte Montage auf Leiterplatten ausgelegt. Es ist aber auch eine rechteckige oder quadratische Formgebung für den Steckverbinder ausführbar.
Darüber hinaus ist vorgesehen, die elektrischen Kontakte, neben ihrem Einclipsen in entsprechende Ausnehmungen des Kontaktträgers, direkt in dessen Kunststoffkörper einzubetten.The electrical contacts are formed as wire contacts and are engaged in longitudinal grooves respectively in corresponding grooves in the four segments of the contact carrier, so that the over-pushed round body securely receives the contacts.
The electrical contacts are optionally designed as a pin as well as a socket contact.
The circular connector preferably shown here is presented in a straight and angled version and is designed for direct mounting on printed circuit boards. But it is also a rectangular or square shape for the connector executable.
In addition, it is provided to embed the electrical contacts, in addition to their clipping into corresponding recesses of the contact carrier, directly in the plastic body.
In einer bevorzugten Ausbildungsform ist der Steckverbinder in einer abgewinkelten Bauform zur Montage auf einer Leiterplatte vorgesehen.
Für diese gewinkelte Version ist erstmals ein Schirmkreuz entwickelt worden, dass vorteilhafterweise auch die senkrechte Abbiegung der elektrischen Kontakte berücksichtigt, so dass die gesamte Länge der Kontakte, von der Steckseite bis zur Anschlussseite auf der Platine unterbrechungsfrei abgeschirmt ist.In a preferred embodiment, the connector is provided in an angled design for mounting on a printed circuit board.
For this angled version, a shield cross has been developed for the first time, which advantageously also takes into account the vertical deflection of the electrical contacts, so that the entire length of the contacts, from the plug side to the connection side on the board is shielded without interruption.
In erster Linie ist vorgesehen, dass der Steckverbinder zunächst keine weitere abschirmende Außenhülle aufweist, da die Endmontage zusammen mit der Leiterkarte zumindest innerhalb eines alle Bauteile umfassenden, abschirmenden Gehäuses erfolgt.
In einer weiteren Ausbildungsform kann der Steckverbinder jedoch auch in eine ihn direkt umgebende elektrisch leitende Hülle eingeschoben werden. Es sind jedoch auch Anwendungsfälle vorgesehen, einen oder mehrere auf einer Leiterplatte fixierte Steckverbinder innerhalb eines elektrisch nicht leitenden Gehäuses anzuordnen, wobei der Steckverbinder in einen elektrisch leitenden Frontplatteneinsatz innerhalb einer elektrisch leitenden Frontplatte eingeschoben wird, so dass der Frontplatteneinsatz gleichzeitig eine Befestigungsmöglichkeit für den zu steckenden Gegensteckers bildet.
Hierbei ist der Steckverbinder bzw. der Rundkörper "schwimmend" gelagert, d.h. er ist nur auf der Leiterplatte gehalten, während der zugeführte Gegenstecker vorteilhaft in einer Verschraubung eines Frontplatteneinsatzes gehalten wird. Wobei die Verschraubung als Hülse geformt, zwar über den Rundsteckverbinder reicht, die beiden aber nicht fest miteinander verbunden sind, jedoch die abschirmende Wirkung mittels der Schirmfeder vollzogen wird.First and foremost, it is provided that the connector initially has no further shielding outer shell, since the final assembly takes place together with the circuit board at least within a shielding housing comprising all components.
In a further embodiment, however, the connector can also be inserted into an electrically conductive sheath surrounding it directly. However, there are also applications provided to arrange one or more fixed on a printed circuit board connector within an electrically non-conductive housing, wherein the connector is inserted into an electrically conductive front panel insert within an electrically conductive front panel, so that the front panel at the same time a mounting option for the plug Mating plug forms.
Here, the connector or the round body "floating" is stored, ie it is held only on the circuit board, while the mating connector is advantageously held in a screw of a front panel insert. Although the screw is shaped as a sleeve, although extends over the circular connector, but the two are not firmly connected, but the shielding effect is performed by means of the shield spring.
Weiterhin ist zweckmäßigerweise in einer weiteren Ausbildungsform eine gerade Bauform des Steckverbinders vorgesehen, die senkrecht auf eine Leiterplatte zu montieren ist.
Hierbei sind alle eingefügten elektrischen Kontakte von der gleichen Bauform.Furthermore, a straight design of the connector is expediently provided in a further embodiment, which is to be mounted perpendicular to a printed circuit board.
Here are all inserted electrical contacts of the same design.
