Multichannel optical coupling configuration

摘要

A coupling system includes an optical plug-in connector, a coupling partner and a retaining element. The housing of the plug-in connector is provided with a sliding key and with two springy detent limbs which include a detent nose for engaging with the coupling partner. In order to receive the plug-in connector, the coupling partner is provided with a plug inlet which has recesses that correspond to the detent noses of the plug-in connector. A retaining element includes a laterally displaceable outer housing and an inner housing that is pivotally arranged therein. A locking element is provided as a two-limb lever that is arranged on the inner housing and that serves to lock the plug-in connector in the retaining element. When inserting the plug inlet, this locking is released once the plug-in connector and plug inlet are engaged with one another.
