Abstract: The locking mechanism (15) is provided at both of its ends with cams (2?, 2?) with axes (21?, 21?) of rotation, while the rotating cams (2?, 2?), each with an impact tooth (3) and brace spike (4), are joined with a rotatable control lever (1) arranged between them, through transmission drawbars (5?, 5?). The locking mechanism (15) has a control lever (1) which axis (20) of rotation is arranged between axes (21?, 21?) of rotation of cams (2?, 2?) and is parallel with them. The axes (21?, 21?) of rotation of cams (2?, 2?) define plane (22) at a distance (s) from the axis (20) of rotation of the control lever (1), while the distance (s) stands for a perpendicular distance between the plane (22) and the axis (20) of rotation of the control lever (1).

Abstract: The locking insertion mechanism (15) is equipped with thrust components, bumper components, the control lever (1) and with reversibly horizontally sliding mechanism of the locking slider (6) with a safety component for securing the control lever (1) in its secure closed position during the defined insertion of the plug-in component (10) into the guide frame (11) and the previously-defined axial connection of optical and/or electronic connectors (8) in connector casings (9) in their axes. The method for performing the plug-in connecting of the optical and/or electronic connectors (8) into the connector casings (9) is performed in three phases.
