Abstract: The present invention provides a twist prevention socket and an electrical device having the socket. The socket of the present invention includes a housing and a first plug, which is provided in an insertion part of the housing. The socket further includes a mediating structure, which includes a first connection member, which is connected to the first contact member of the second plug, and a second connection member, which is connected to the second contact member of the second plug and is electrically isolated from the first connection member. The socket further include a locking structure, which includes an elastic compressing member that is provided adjacent to the second plug and the mediating structure to ensure no-load operation of the second plug with respect to the mediating structure and provide a predetermined amount of resistance to removal of the second plug from the mediating structure.

Abstract: Disclosed therein is a wet-and-dry-type hair iron for curling, which has a moisture discharge structure capable of curling hair in a state where hair is wet when hair is curled by heating hair for permanent wave of hair, so that a user can simultaneously carry out hair drying and curling when hair is curled just after washed, and which has a power line connection member capable of idling and being freely attached and detached to preventing twisting of a power line so that it can provide, convenience in carrying and arrangement.

Abstract: The present invention provides a twist prevention socket and an electrical device having the socket. The socket of the present invention includes a housing and a first plug, which is provided in an insertion part of the housing. The first plug is connected to a jack of a power cord. The socket further includes a second plug, which is provided in the housing at a position opposite the first plug and has a first contact member and a second contact member, which are connected to respective connection wires connected to the first plug. The first and second contact members are prevented from being electrically connected to each other, and have an arrangement of concentric circles. The socket further includes a mediating means, which includes a first connection member, which is connected to the first contact member of the second plug, and a second connection member, which is connected to the second contact member of the second plug and is electrically isolated from the first connection member.

Abstract: Disclosed herein is a hair curling iron. The hair curling iron of the present invention includes an iron body and a compression clip assembly. The iron body has a heating body having a bar shape with a circular cross-section, and a handle which is coupled to an end of the heating body. The compression clip assembly has a compression clip having an arc cross-section corresponding to an outer surface of the heating body. The compression clip assembly is coupled to the heating body such that the compression clip detachably contacts the outer surface of the heating body. The compression clip assembly further has a clip cover which is coupled to the compression clip such that a space is defined between the clip cover and the compression clip, and a clip heater which is inserted into the space defined between the clip cover and the compression clip.
