Plug-in connector for high data transmission rates
A so-called QSFP-plug-in connector is suggested for high performance-plug-in connections in data centers, which comprises a one-piece metallic exterior housing and in which a one-piece locking device is embodied, which via a latch attached thereat can be released from an appropriately embodied cage-like counter connector. Here, a circuit board is provided for the direct plug-in connection in copper-based twin-axial cable connections which is connected inside the exterior housing with electric conductors arranged therein. The electric conductors are held in axially aligned grooves via a fixing clip encompassing them.
1. A plug-in connector ( 1 ) for lockable and unlockable engagement with a counter connector ( 2 ), the counter connector having electrical contacts therewithin, wherein said plug-in connector ( 1 ) comprises an exterior housing ( 10 ) defining an open plug-in side ( 11 ) for engagement with the counter connector ( 2 ) and a cable connector side ( 14 ) for receiving an electric cable ( 5 ) having a plurality of individual conductors ( 6 ), a locking mechanism ( 30 ) within said exterior housing ( 10 ) for lockable engagement with the counter connector ( 2 ), a fastening frame ( 20 ) within said exterior housing ( 10 ) extending between the open plug-in side and the cable connector side, said fastening frame ( 20 ) defining a cable manager formed by a plurality of longitudinal grooves ( 21 ) to receive the plurality of individual conductors in a side-by-side relationship, a fixing clip ( 24 ) arranged transversely to said longitudinal grooves ( 21 ) to hold the individual conductors within the longitudinal grooves and adjacent to a circuit board ( 50 ), said individual conductors connected to said circuit board ( 50 ), said circuit board connected to said fastening frame ( 20 ) and extending into the open plug-in side of said exterior housing ( 10 ) for making direct contact with the electrical contacts of the counter connector ( 2 ) when the exterior housing ( 10 ) is in lockable engagement with the counter connector ( 2 ), and an unlocking latch ( 40 ) extending outwardly from the exterior housing ( 10 ) and manually shiftable to unlock the exterior housing ( 10 ) from the counter connector ( 2 ).
2. The plug-in connector according to claim 1 , wherein the exterior housing ( 10 ) is secured to the fastening frame ( 20 ) and the locking device ( 30 ) via fastening screws ( 29 . 2 ) and a cable clamp ( 29 ).
3. The plug-in connector according to claim 1 , wherein the exterior housing ( 10 ) is embodied in one piece, the fastening frame ( 20 ) is embodied in one piece, and the locking device ( 30 ) is embodied in one piece.
