ABSTRACT:
An electrical receptacle is provided herein which has a special locking mechanism preventing the plug from falling off. The receptacle mainly contains a body housed inside a sleeve. The body has at least a locking blade with a bended portion extended out of the body and pressed against the inside of the sleeve. A slot opening on the bended portion is roughly aligned with the slot of the body. When the prong of a plug is inserted into the sleeve, the sleeve presses the bended portion so that the slot opening and the slot on the body are completely aligned and the prong could go all the way into the slot of the body. The bended portion of the locking blade then springs back to a slant position to lock the prong. To unplug, the pulling force applied to the plug drags the body toward the sleeve which again presses the bended portion of the locking blade so that the prong could be pulled out of the slot of the body easily.
