This invention relates to electrical plugs capable of being easily removed from their associated receptacles with the aid of a pull ring. This improved pull ring is either pulled or pushed only in the direction that is perpendicular to the prong side of an electrical plug whereby making the storage and operation of the pull ring much easier to operate than the typical pull-ringed electrical plug arrangements that are currently available.

The present invention is related to an improved electrical receptacle such that more than one of such electrical receptacles are capable of being electrically coupled together without electrical wires. This feature is particularly advantageous for power adapter products such as power strips and extension boxes. A preferred embodiment includes an electrical receptacle having metal contact strips extending outward from two opposite side faces of its receptacle housing. These metal contact strips are adapted to be separately and electrically coupled to the hot, neutral and ground prongs of an inserted power plug. The receptacle is further configured so that when the metal-strip sides of two of such receptacles are disposed in close proximity of each other, the metal contact strips of the receptacles would then be physically paired. The metal contacts are paired in a manner whereby electrical connection is established and whereby the two receptacles are easily fastened. The present invention reduces or eliminates the need for wire usage in receptacle coupling, and as a result, minimizes the risks of electrical shorts and fires.

A replaceable wall plate is disclosed. It includes a replaceable portion and a wall plate portion. The wall plate portion is typically screwed to a wall to form the cover of a wall outlet whereas the replaceable portion is removably attached to the wall plate portion. The removable attachment scheme is preferably accomplished for the two portions using the methods of prong insertion, button coupling or channel sliding. The replaceable portion further contains built-in electronics such as a surge protection device. It is configured in the replaceable portion for protecting electrical devices plugged or connected to the receptacles of this wall outlet. Accordingly, the replaceable portion along with its built-in surge protection device could be replaced such as in the case of electronics failure after an abnormal electrical event, for example, a voltage spike. In addition, in order to lengthen operation life, the replaceable portion is configured such that the surge protection device receives electricity only when a plug is inserted through the receptacle.

A corner-sitting power strip is provided for overcoming the disadvantages of the existing power strips. Briefly, the present invention is able to operate like a typical power strip and is further configured to sit snugly on a corner. While electrical plugs of appliances and equipment are coupled with the multiple receptacles of the power strip, a base face of the strip housing snugly pushes against one side of the corner, and another base face of the same housing snugly pushes against another side of the corner. At the same time, the dimensions of the housing is designed such that electrical cords of inserted plugs are channeled out from the power strip in a generally parallel fashion either projecting upward against one side of the corner or projecting downward against the other side of the corner. In this manner, in addition to the typical ability to lie flat on a surface as a typical power strip, the space savings, cord management and increased stability advantages of the present invention are also substantively realized.

Portable corner-sitting power strip

A wall-mounted electrical receptacle adapter is provided and is configured for receiving contact blades of electrical cable plugs. A first adapter surface of the receptacle adapter contains the prong apertures and operatively makes contact with the contact blades of at least one electrical plug. This first adapter surface is disposed slanted downward at an angle relative to the wall side of the receptacle adapter. A second adapter surface disposed below the first adapter surface also being slanted downward at generally the same angle relative to the wall side as the first adapter surface. The slanting angles of the adapter surfaces allow the power cable to naturally and orderly extend downward toward the ground without making sharp angles at the plug end whereby lengthening the operational life of the power cables. In another embodiment, the slanting angles for the two adapter surfaces are different, whose angle measures one being greater than the other.
