Structure of an electrical socket

Claim 2

A structure of an electrical socket, comprising: a faceplate provided with one or more than one receptacle, said receptacle being provided with two slots, a rectangular recess being formed on said faceplate outside of said slots, and a tongue being provided between said slots corresponding to the length of said slots, said slots being each provided with a slide groove at an outer side thereof; and a cover plate being received in said recess of said receptacle and having a length substantially corresponding to the distance from bottom edges of said slots to a bottom edge of said recess, said cover plate including an indentation at an upper end shaped and sized to match and receive said tongue and two side wings each of which extends downwardly to form a hook for engaging the corresponding slide groove, said cover plate being disposed in said recess such that said side wings at said slots touch said tongue; whereby when said cover plate is not pushed, said slots of said receptacle are exposed on said faceplate to allow insertion of a plug, and when said cover plate is pushed so that said hooks at both sides thereof slide forwardly along said slide grooves until said indentation completely receives said tongue with said side wings concealing said slots, thereby achieving a safety electrical socket.

Claim 3

A structure of an electrical socket as defined in claim 1, wherein said receptacle further includes a grounding slot below said slots, said grounding slot being located in said indentation when said cover plate is not pushed and being concealed by said cover plate when said cover plate is pushed forwardly in said recess.

Claim 4

A structure of an electrical socket as defined in claim 1, wherein said cover plate further includes a threaded portion to facilitate pushing of said cover plate by fingers.

Claim 5

A structure of an electrical socket, comprising: a faceplate being provided with one or more than one receptacle, said receptacle being provided with two slots, a rectangular recess being formed on said faceplate outside of said slots, said recess being provided with two slide grooves at opposed outer sides below said slots respectively; and a cover plate received in said recess and having a length corresponding to the distance from top edges of said slots to a bottom edge of said recess, said cover plate including two hooks extending downwardly from both lateral sides thereof to correspond to said slide grooves of said recess, whereby said hooks may be inserted into said slide grooves when said cover plate is disposed in said recess, said coverplate further including two cover slots corresponding to said slots of said receptacle; whereby when said cover plate is not pushed, said cover slots of said recess are in registration with said slots of said receptacle to allow insertion of a plug, and when said cover plate is pushed such that said hooks thereof advance along said slide grooves until a top edge of said cover plate abuts against a top edge of said recess, said slots are concealed, wherein a groove is provided between said slots of said receptacle, said groove being provided with respective retaining holes at both ends and the middle thereof, and said cover plate is providing with bulges at a bottom side thereof corresponding to adjacent retaining holes of said groove to facilitate positioning of said cover plate during displacement.

Claim 6

A structure of an electrical socket, comprising: a faceplate being provided with one or more than one receptacle, said receptacle being provided with two slots, a rectangular recess being formed on said faceplate outside of said slots, said recess being provided with two slide grooves at opposed outer sides below said slots respectively; and a cover plate received in said recess and having a length corresponding to the distance from top edges of said slots to a bottom edge of said recess, said cover plate including two hooks extending downwardly from both lateral sides thereof to correspond to said slide grooves of said recess, whereby said hooks may be inserted into said slide grooves when said cover plate is disposed in said recess, said coverplate further including two cover slots corresponding to said slots of said receptacle; whereby when said cover plate is not pushed, said cover slots of said recess are in registration with said slots of said receptacle to allow insertion of a plug, and when said cover plate is pushed such that said hooks thereof advance along said slide grooves until a top edge of said cover plate abuts against a top edge of said recess, said slots are concealed, wherein a groove is provided between said slots of said receptacle, said groove being provided with respective retaining holes at both ends and the middle thereof, and said cover plate is providing with bulges at a bottom side thereof corresponding to adjacent retaining holes of said groove to facilitate positioning of said cover plate during displacement.

Claim 7

A structure of an electrical connector as defined in claim 4, wherein said receptacle further includes a grounding slot below said two slots, and said cover plate further includes a lower slot below said two cover slots to match said grounding slot, said grounding slot being in register with said lower slot of said cover plate when said cover plate is not pushed forwardly but being concealed by said cover plate when said cover plate is pushed.

Claim 8

A structure of an electrical socket as defined in claim 4, wherein said cover plate further includes a threaded portion to facilitate pushing of said cover plate by fingers.

Claim 9

A structure of an electrical socket as claimed in claim 5, wherein said groove extends to said grounding slot.
