Abstract
A plug portion (1) for an optical plug connector has a plug casing (2) in which at least one connector pin (3) is held. A protective flap (4) for protection of the connector pin is pressed under spring tension against the face (7) of the plug casing. The protective flap is mounted to pivot and slide on an approximately linear guide path (5) in such a way that, on insertion of the plug portion into a sleeve portion, it is able to move from a closed position on the face of the plug casing into an opened position that is set back in relation to the face (7). In order to pre-load the protective flap under spring tension throughout its entire slide- and pivoting-travel, a compression spring is arranged on the plug casing (2) approximately parallel to the guide path (5), said compression spring impinging either directly or indirectly upon the protective flap (4) above the plane of the guide path (5) between the closed position and the opened position.
