Abstract
An electric connector equipped with multiple layers of safety structure includes an insulation case, an electric connection terminal set and a safety mechanism. The insulation case has a front panel with a plurality of slots. The safety mechanism has a safety gate set and a blocking plate latching element. The safety gate set is pushed by a plug and to open the slots to allow the plug to pass through and to establish electric connection with the electric connection terminal set. The blocking plate has a brake portion. The blocking plate latching element has a stirring portion exposed outside the surface of the insulation case and a stop portion corresponding to each blocking plate. The stop portion is movable with the stirring portion to the brake portion to stop the blocking plate from moving. Thereby the blocking plate latching element can control opening of the safety gate set.
