ABSTRACT:
To reduce the engagement force of a multi-terminal plug-and-socket connection, for example having fifty connecting terminals, and reliably positioning the plugs and sockets with respect to each other even upon being subjected to vibration and shock, a handle (13) is provided which is pivoted to the plug element (8, 9) and connected to the plug element by an angled lever (14, 17), the pivot connection (15) being at the end of the angled lever, and, adjacent the apex of the angle of the angled lever, a bolt is located which is operable in a guide track (21), formed as a slit in an upstanding side wall (19) of the socket element (2), the slit being formed with a terminal opening (22) to permit release of the guide bolt (18) from the slit (21) when the handle (13) is raised (chain-dotted position) and consequent disengagement of the plug (8) from the socket (2) by unhooking a pair of interengaging hooks (5, 12) located at the end of the plug-socket connection remote from the handle (13). The arrangement reduces the engagement force required to be applied by an operator for secure interengaging of blade-type terminals by use of the leverage available by the combination of the handle with the angled lever.
