A safety receptacle for power cord includes a main body, a positioning plate, and a sheath. The positioning plate is fixed to the main body, having an elastically swayable active section. The sheath is movably sheathes the main body. The main body, the sheath, and the active section are formed with corresponding insertion holes and aperture. When the plug is inserted in the receptacle, the conductive pin of the plug is clutched by the active section so as to prohibiting slack of the plug. Additionally, the active section contacts the conductive pin by point contact, so that little dust would be produced by abrasion of the active section and the conductive pin. Without the piled dust, ignition is prevented. Safety of the receptacle is then improved. |

1. A safety receptacle for power cord, which is provided for a plug, the safety receptacle having a main body which has a conductive plate disposed therein, the main body having an end surface which is formed with plural inner insertion holes, the main body being sheathed by a sheath, the sheath having a covering surface located at one end thereof, the covering surface being formed with plural outer insertion holes corresponding to the inner insertion holes, the sheath being able to move translationally with respect to the main body in a limited route,
characterized in that: at least one positioning plate is disposed on the end surface of the main body, the positioning plate has a fixation section which is fixed to the main body and an active section which is exposed from the main body, the active section is formed with an aperture corresponding to the inner insertion holes and the outer insertion holes, a distance is defined between the active section and the end surface of the main body so as to define an active area at where the active section is able to sway elastically when the active section is pressed by the sheath, the active section faces toward the inner insertion holes, one of conductive pins of the plug is able to pierce into one of the outer insertion holes, the aperture, and one of the inner insertion holes, inserting into the conductive plate, the conductive pin and an inner periphery of the active section achieve point contact by sides thereof, and width surfaces of the conductive pin contacts no inner periphery of the active section; wherein the main body is formed with plural columns, the inner insertion holes are formed respectively in the columns, and the fixation section of the positioning plate stretches beside and is fixed to a bottom side surface of the columns. |
