SAFE ELECTRICAL OUTLET

摘要

According to the present invention, provided is a safe electrical outlet comprising: a body including a fastening piece for coupling to a plug of an electric device; a plate spring installed inside the body as part of the fastening piece, and of which one end and the other end connected to the one end through a center portion are made from a conductive metal to supply power to the fastening piece; and a plurality of shape memory springs of which one end is fixed to one end on the inside of the body and the other end is fixed to the one end or the other end of the plate spring, wherein the shape memory alloy springs have a shape memory alloy characteristic of separating the plate spring away from the fastening piece at a specific distance by means of deformation. The present invention has the advantages of blocking current by using restoring force of the shape memory alloy springs when heat is generated due to overheating, such as from a short circuit or electrical leakage, thereby preventing safety accidents such as a fire due to overheating from overload, and preventing damage to the electrical device.
