Der erfindungsgemäße Winkel-Steckverbinder ist besonders geeignet zur Führung von hochfrequenten Signalen. Beispielsweise kann ein Digitalsignal bei einer Datenrate bis zu 10 Gigabit mit hoher Güte geführt werden, wobei gleichzeitig eine hohe Signalintegrität sichergestellt ist. Der erfindungsgemäße Winkel-Steckverbinder eignet sich daher insbesondere für signalverarbeitende Anordnungen, bei denen beispielsweise Platinen mit einer Backplane verbunden werden sollen.The angle connector according to the invention enables the realization of a high quality shielding. In particular, a homogeneous inductance coating within the connector is achieved. The angle connector according to the invention is particularly suitable for guiding high-frequency signals. For example, a digital signal at a data rate of up to 10 Gigabit can be performed with high quality, while ensuring high signal integrity. The angle connector according to the invention is therefore particularly suitable for signal processing arrangements in which, for example, boards are to be connected to a backplane.

Vorzugsweise ist vorgesehen, dass das steckerseitige untere Abschirmelement eine homogene Verbindungsfläche ohne Ausnehmungen oder Aussparungen aufweist, die sich über eine Mehrzahl von Kontaktelementen, vorzugsweise über sämtliche Kontaktelemente erstreckt. Diese Maßnahme trägt ebenfalls zur Realisierung einer möglichst vollständigen Abschirmung der Kontaktelemente bei.One embodiment provides for the realization of the connecting surfaces as planar connecting surfaces. It is preferably provided that the plug-side lower shielding element has a homogeneous connection surface without recesses or recesses, which extends over a plurality of contact elements, preferably over all contact elements. This measure also contributes to the realization of a complete shielding of the contact elements.

Das Laserschweißen bietet die Möglichkeit zur Herstellung des elektrischen Kontakts zwischen den unteren Abschirmelementen auch an schwer zugänglichen Stellen innerhalb des Steckverbindergehäuses. Sofern die Verbindungsflächen der unteren Abschirmungen innerhalb des Steckverbindergehäuses liegen, kann der Laserstrahl durch eine vorhandene Öffnung im Steckverbindergehäuse bis an die Verbindungsstelle herangeführt werden.The inventive method for producing the angle connector provides a welded connection at least the lower shielding by means of laser welding previously. The laser welding offers the possibility of establishing the electrical contact between the lower shielding elements even in hard to reach places within the connector housing. If the connecting surfaces of the lower shields are within the connector housing, the laser beam can be introduced through an existing opening in the connector housing to the connection point.

Die Kontaktelemente 2 sind in einem isolierenden Steckverbindergehäuse 5 untergebracht, das von einer Abschirmung 6, 7 abgeschirmt ist, die vereinfacht dargestellt ist. Die Abschirmung setzt sich aus einer oberen Abschirmung 6 und einer unteren Abschirmung 7 zusammen.
