Abstract
A five-hole socket with safety shutters adopts the scheme that a two-hole safety shutter is arranged below a two-hole socket of a middle cover, a two-hole safety shutter spring used for pushing the two-hole safety shutter to be opened and closed is arranged at the middle part of the two-hole safety shutter, a bracket used for supporting the two-hole safety shutter is arranged at the rear part of the two-hole safety shutter, a three-hole safety shutter is arranged below a three-hole socket of the middle cover, and a three-hole safety shutter spring used for pushing the three-hole safety shutter to be opened and closed is arranged at the middle part of the three-hole safety shutter. The five-hole socket with the safety shutters has the following benefits: (1) when a metallic component single pole is inserted into the two-hole socket, the two-hole safety shutter is stuck so as not to be pushed open; and when the metallic component double pole is inserted into two inclined surfaces on the two-hole safety shutter of the socket, the two-hole safety shutter can be smoothly pushed open along a convex sliding rail, so that the security of the socket is reliable; and (2) the three-hole safety shutter can be smoothly pushed open so long as the pressure is applied to a bump provided with a groove inclined surface in a ground wire hole of the three-hole socket by a plug or other objects, so as to greatly improve the security of the socket.
