ABSTRACT:
An electric plug and socket connector comprises a base provided with movable contacts resiliently urged towards their contact position, a plug provided with fixed pins, and a rotary safety disc which in its resting position masks the movable contacts and which is provided with as many openings as there are pins on the plug, sized and arranged suitably to enable the pins to pass through them and to become applied end-wise on the movable contacts after rotation of the disc. The angular locking or detention in the resting position and in the contact position of the safety disc is ensured at least in part by projecting insulating elements connected to the movable contacts and urged by the resilient means of the latter to be engaged in the resting position and in the contact position in separate recesses formed in the disc. The recesses determining the latter position are substantially coaxial with the openings of the disc while the surfaces and shapes respectively of the projecting elements and of the recesses, are suitably chosen to cooperate and to enable the obtaining by a maneuver of simple rotation of the disc, at the beginning and at the end of the maneuver, respectively, withdrawal of the elements and an engagement of the latter in the recesses. Arcing effects are thereby minimized.
