Embodiment

Below in conjunction with drawings and Examples, the utility model is described further:

Embodiment 1: as shown in Figure 1-Figure 3, the portable socket that can receive power cord plug described in the present embodiment, comprises plug 1, power line 2 and housing; In described housing, be provided with the transformation rectification module 14 being electrically connected with power line 2, the circuit of this transformation rectification module is identical with prior art transformation rectification circuit, belong to the state of the art, described housing is provided with the usb 15 being electrically connected with transformation rectification module 14 outputs, utilize transformation rectification module 14 that 220V alternating current is converted to 5V direct current, and export by usb 15.Described housing comprise interconnect and can relative sliding to realize upper shell 3 and the lower house 4 of opening and closing, wherein upper shell 3 surfaces are power plug groove face, be provided with and can under opening, prevent that both from departing from, can under closure state, realize the position-limit mechanism of both relative positionings mutually simultaneously between described upper shell 3 and lower house 4; Described upper shell 3 comprises the shell 3-1 matching with lower house 4, the inner casing 3-2 that is fixedly connected with this shell and protrudes to lower house 4 one sides, and described usb 15 has two, is separately positioned on shell 3-1 upper surface and side.Under closure state, in described inner casing 3-2 embedding lower house 4, and between forms one for being wound around the winding slot 5 of power line 2; Under opening, described inner casing 3-2 is exposed to outside, to facilitate the winding of power line 2.
