Abstract
Disclosed is a new way to lock an extension cord to and electrical tool or to another extension power cord, preventing unwanted separation. The locking connector is suitable for home and commercial use, indoors or outdoors.
The locking extension power cord comprise a female electrical power receptacle assembly having a dielectrical blade that can be press downward on to the male electrical connector prongs from and electrical tool or another extension cord by the simple operation of sliding a carrier with and elevation on its under side over the said blade, therefore pressing the dielectrical blade downward against the prongs of the male end of and electrical power cord and therefore locking it inside the connector sockets.
This invention relates to a device that will keep electrical extension cord from unwanted separation, only the female end of the electrical cord as been change to lock up the two together. This invention will improve safety when using an electrical tool by giving the operator a non interrupted source of power for commercial or residential use indoors or outdoors.

Description
" 218361)0 The previous electrical connecting devices demanded that the male end of the electrical cord be change to become part of the locking system of the invention, making its use non practical having to change the male end connector p~rt of all tovls, with this new invention it no longer re~uired to change the male connector part, therefore it iS more pr~ctical.
In drawing which illustrate embodiments of the invention, figure 1 is a side elevation view of a female 0 receptacle of the present locking connector for an exten~ion power cord at an unlock position figure 2 is a side elevation view of the invention showing the male and female end of a power cord mated and locked together figure 3 is front elevation view of the invention - at an unlock position figure 4 is a front elevation view of the invention at lock position " - ' 21836~0 The illustrated device comprise a female end 6 of ~ l el*..+.~ric~l po~er cor~ ith ~ ring 2 or a carrier 3 that can be turn or slide over a dielect,rical blade 1 and therefc)re pushing the said dielectrical blade 1 down against the prGngs 7, sq~leezing the prongs 7 down inside their c,!nnec~tor sockets S ar.d keeping the prongs 7 from sliding out.
The ring 2 as an elevation 4 to its underside and can be turn clock or counter clock wise around the female receptacle 6 and over the dielectrical blade 1, therefore the elevation 4 on the underside of the ring 2 can be place asidc as in figure 3 or over as in figure 4 the dielectrical blade 1 and therefore locking or unlocking the prongs 7 inside the connector sockets 5.
The carrier 3 as illustrated in figure 1 and 2, can slide back and forth on a track 8 in~ide the female receptacle 6 of the extension cord near the surface of the female receptacle 6, when the carrier 3 is slide over the dielectrical blade 1 it presses down on the said blade 1 and squeeze the prongs 7 and therefore prevents the male end 10 of the cord of an electrical tool to slide out of its connector sockets 5 and interrupting the source of power.
W~.en the carrier 3 is slide back away from the ~lade 1 the prongs 5 carl move freely as illustrated in figure 1, The dielectrisal blade 1 is L shape and is attach at its holding point 9, the said blade 1 is made of a dielectLical and also resilient material therefore when no pressure is exert downward on the blade 1 it re~ain its upper position and out of the way of the prongs 7.

The ring 2 as an elevation 4 to its underside and can be turn clock or counter clock wise around the female receptacle 6 and over the dielectrical blade 1, therefore the elevation 4 on the underside of the ring 2 can be place asidc as in figure 3 or over as in figure 4 the dielectrical blade 1 and therefore locking or unlocking the prongs 7 inside the connector sockets 5.
The carrier 3 as illustrated in figure 1 and 2, can slide back and forth on a track 8 in~ide the female receptacle 6 of the extension cord near the surface of the female receptacle 6, when the carrier 3 is slide over the dielectrical blade 1 it presses down on the said blade 1 and squeeze the prongs 7 and therefore prevents the male end 10 of the cord of an electrical tool to slide out of its connector sockets 5 and interrupting the source of power.

Claims (2)
1. A locking female end of an electrical power cord comprising:
A dielectrical resilient blade that is press down on the prongs of a male end of an extension cord by a ring having and underside with and elevation, the said ring can turn clock or counter clock wise around the said female receptacle of and electrical cord, therefore when the elevation of the said ring is place over the dielectrical resilient blade the said blade is press downward on to the prongs of a male end of and electrical cord squeezing the prongs down in the connectors sockets and therefore preventing them from sliding out, when ring is turn and elevation is move off the said dielectrical resilient blade, the said blade returns to its upward position.
A dielectrical resilient blade that is press down on the prongs of a male end of an extension cord by a ring having and underside with and elevation, the said ring can turn clock or counter clock wise around the said female receptacle of and electrical cord, therefore when the elevation of the said ring is place over the dielectrical resilient blade the said blade is press downward on to the prongs of a male end of and electrical cord squeezing the prongs down in the connectors sockets and therefore preventing them from sliding out, when ring is turn and elevation is move off the said dielectrical resilient blade, the said blade returns to its upward position.
2. The locking female end of end electrical power cord of claim 1> Wherein the said blade can be press downward by a carrier that slides forward or backward on a track provided inside the female end receptacle and near the surface wherein carrier can be push over the said dielectrical resilient blade forcing the blade downward and therefore squeezing the prongs of a male end electrical cord and preventing the said male end connector to slide out of the connector sockets, to release the prongs, slide carrier off and aside the dielectrical blade and the resiliency of the blade will bring the blade back to its upward position and therefore free the prongs.
