## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to electrical power receptacles, and, more particularly, to snap-in electrical receptacles with multiple outlet possibilities.
2. Description of the Related Art
In many applications, electrical receptacles are needed to receive and distribute power. They are required in permanent locations such as walls in fixed structures, as well as temporary locations such as modular office furniture. Many types of receptacles are required according to the needs of users. Some receptacles, for example, include distribution of power for computers, telephones, and corded appliance, etc. The electrical receptacles also are required in places that are convenient for the user, and may need to be re-located.
It is known in the art to have electrical receptacles that are attached to supporting surfaces via fasteners, typically screws. It is also known in the art to permanently attach electrical receptacles to supporting surfaces. It is further known in the art to require access to the back of the receptacle in order to remove it from the supporting surface.
Depending upon the types of electrical receptacles and the applications in which they are used, various problems can be encountered. One problem is the reliance upon screws or other fasteners to secure the electrical receptacles to their respective supporting surfaces. Using fasteners makes installation and removal cumbersome and prone to failures. It also requires a mating configuration at each desired location.
Another problem that can be encountered is that very little modularity is available with current electrical receptacles; that is, they are typically limited as to their electrical input ports and electrical outlet configurations.
A further problem that can be encountered is the inability to easily install the electrical receptacle and remove it at a later time, and further to use the same receptacle in a different location.
What is needed in the art is an apparatus that can receive and distribute power and can be installed and removed easily into openings of supporting surfaces.
SUMMARY OF THE INVENTION
The present invention is directed to an improved electrical power receptacle with features that allow it to be snapped in to an opening of a supporting surface, and easily removed if desired.
The present invention provides a snap-in electrical power receptacle for providing a power inlet and outlet to desirable locations, insertable into openings in support surfaces without tools or extraneous fasteners.
The present invention further provides a snap-in electrical power receptacle with at least one elastically deformable manner that displaces while the receptacle is being inserted, and returns to its original position when the receptacle is fully seated.
The present invention further provides a snap-in electrical power receptacle variably configured with electrical outlets and electrical input ports.
An advantage of the present invention is that the snap-in electrical power receptacle can be easily installed in an and remain secured to an opening of a supporting surface, without tools or extraneous fasteners.
Another advantage of the present invention is that the snap-in electrical power receptacle can be removed from the opening in the supporting surface without the necessity of removing or loosening extraneous fasteners.
Yet another advantage of the present invention is that the snap-in electrical power receptacle can be removed from the front; that is, it can be removed without needing to access the inventive receptacle from behind the supporting surface.
Still another advantage of the present invention is that the snap-in electrical power receptacle can be configured with a variety of electrical inlet ports and electrical outlets.
Yet another advantage of the present invention is that the snap-in electrical power receptacle can be used in any supporting surface including walls, tables, ceilings, floors, raceways, columns, posts, etc.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIGS. 1-3, there is shown an embodiment of a snap-in electrical receptacle assembly 10 according to the present invention. Snap-in electrical receptacle assembly 10 includes housing 12 and face plate 16.
Housing 12 of snap-in electrical receptacle assembly 10 includes a plurality of sides 14, a back 26, a front opening 28 (not illustrated), a length L2, and a width W2. Housing 12 further includes at least one electrical input port 36 on at least one of the plurality of sides 14. The at least one electrical input port 36 can be on any of the at least one of the plurality of sides 14; FIGS. 1-2 illustrate one possible configuration.
The at least one electrical input port 36 can be any type of electrical input port; although a two-wire port is shown, a three-wire port or any other electrical input port 36 may be included. Additionally, housing 12 may include one type of electrical input port 36 or a mixture of different types.
Housing 12 further includes a bisecting plane BP (see FIG. 3), which divides the housing 12 into two parts. An additional bisecting plane BP2 (not shown) may also be included, which is perpendicular to bisecting plane BP.
Housing 12 further includes at least one L-shaped member 20 on at least one of the plurality of sides 14. The at least one L-shaped member 20 can be on any of the at least one of the plurality of sides 14; FIGS. 1-2 illustrate one possible configuration.
The at least one L-shaped member 20 includes a shelf 22 with a top surface 38 and a bottom surface 40, and further includes an inclined protrusion 24. The at least one L-shaped member 20 may further include a slot 42 in the shelf 22. The purposes of the shelf 22, inclined protrusion 24, and slot 42 are described further in this specification.
The at least one L-shaped member is configured so that the shelf 22 and inclined protrusion 24 can flexibly move toward bisecting plane BP when a force is applied to it and then away from bisecting plane BP when the force is removed from it.
Face plate 16 includes a front surface 30, a back surface 32, a notch 34, a length L2, and a width W2. Face plate 16 further includes at least one electrical outlet 18 on front surface 30. The at least one electrical outlet 18 can be any type of electrical input port; although a Universal Serial Bus (USB) outlet is shown, an alternating current (AC) outlet (see FIG. 6) or any other electrical outlet 18 may be included. Additionally, face plate 16 may include one type of electrical outlet 18 or a mixture of different types.
Face plate 16 and housing 12 can be manufactured as a single unit, or face plate 16 can be attached to housing 12 with a plurality of fasteners 56, for example. When the electrical receptacle assembly 10 is assembled, the top surface 38 of shelf 22 of the at least one L-shaped member 20 is flush with the front surface 30 of face plate 16. Additionally, the shelf 22 of the at least one L-shaped member 20 fits within the notch 34 of face plate 16.
Now referring to FIG. 4 with continued reference to FIGS. 1-3, a method of installing the snap-in electrical receptacle assembly 10 in a supporting surface 46 is described hereby. Supporting surface 46 can be any surface such as a wall, a table, a ceiling, a floor, a raceway, a column, a post, or any other surface where an electrical receptacle is desired in a permanent or temporary location. Supporting surface 46 includes back face 48, front face 50, and opening 44.
As previously mentioned, housing 12 includes an inclined protrusion 24 on the at least one L-shaped member 20. Inclined protrusion 24 protrudes a depth P1 from one of the plurality of sides 14.
To install snap-in electrical receptacle assembly 10 in the supporting surface 46, the back 26 of housing 12 is inserted into the opening 44, which is dimensionally larger than L2 and W2 of housing 12 but dimensionally smaller than W2 of housing 12 plus P1 of inclined protrusion 24. As the housing 12 continues to be inserted into opening 44, the inclined protrusion 24 and shelf 22 are flexibly urged under elastic deformation toward bisecting plane BP. When the inclined protrusion 24 clears the back face 48 of supporting surface 46, the inclined protrusion 24 and shelf 22 are free to move back to their original position.
At this point, which is the final position of the snap-in electrical receptacle assembly 10, the top surface 60 of the inclined protrusion 24 prevents the snap-in electrical receptacle assembly 10 from being pulled from the opening 44 as a result of its contact with the back face 48 of supporting surface 46. The snap-in electrical receptacle assembly 10 is prevented from further insertion into opening 44 as a result of the back surface 32 of face plate 16 contacting the front face 50 of supporting surface 46, and the dimensions L1 and W1 being greater than the corresponding opening 44 dimensions.
To remove snap-in electrical receptacle assembly 10 in the supporting surface 46, the shelf 22 of at least one L-shaped member 20 is urged toward bisecting plane BP, which in turn displaces inclined protrusion 24 toward bisecting plane BP. This displacement allows a housing-only dimension of W2, which is smaller than the corresponding opening 44 dimension, and the snap-in electrical receptacle assembly 10 can be completely removed.
Alternatively, and as mentioned above, the at least one L-shaped member 20 can include a slot 42 in the shelf 22. The slot 42 can either be countersunk in shelf 22, or pass all the way through it. If desired, a tool may be placed in slot 22 to assist in the urging of the at least one L-shaped member 20 toward bisecting plane BP.
Now referring to FIGS. 5-6, alternate embodiments of snap-in electrical receptacle assembly 10 are shown.
In both FIGS. 5 and 6, embodiments are shown wherein housing 12 further includes an attached cord or wire that is instead of or in addition to the at least one electrical input port 36. In FIG. 5, an alternate embodiment is shown wherein a switch 54 is shown instead of the electrical outlet 18. FIG. 6 shows another alternate embodiment, wherein an AC outlet is shown as the electrical outlet 18, as described above. It is to be understood that embodiments of the invention may include any combination of switch 54 and/or electrical outlet 18.
While snap-in electrical receptacles have been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
