Description

FIELD OF THE INVENTION

Embodiments of the present invention generally relate to an extension cordset assembly having a male plug and a female receptacle, and more particularly, to a water-resistant locking extension cordset assembly.

BACKGROUND OF THE INVENTION

Extension cordsets are used in homes and businesses in order to connect appliances and electronic equipment to a source of power. Typically, cordsets are designed for indoor use and configured to carry 10 amperes or less of current. Other common heavy-duty cordsets are designed to provide power to tools or machinery. While the heavy-duty cordsets may be rated for outdoor use, the rating typically applies to the water resistance of the plastic jacketing on the cord and molded pieces without addressing the ability of the cordset connections to resist moisture.

A large proportion of outdoor cordsets are used in agricultural or construction settings where they provide power for operating a hand-held power tool such as a drill or circular saw. The extension cordsets in these settings allow a user to operate a tool at a remote distance from a power outlet. Thus, the user may move about a work site with the tool.

The male plug of a tool, however, may be susceptible to disconnecting from the female receptacle of an outdoor cordset. In order to prevent the male plug from disconnecting from the female receptacle, some users tie an end of the power tool cord and an end of the extension cordset in a knot. However, the act of physically tying the cords together may be annoying to some users. Additionally, the knotted connection may not always be secure. Further, tying the cords together inherently decreases the length of the extension.

Also, the interface between the extension cordset and the power tool cord may be exposed to water, for example, in a puddle, where the cord may short to ground. Alternatively, the male plug and the female receptacle may partially disengage from one another, thereby exposing live electrical contacts. As such, typical extension cordsets may present a danger to users and others as well as presenting a fire hazard. This same hazard can be found in cordsets for supplying power to recreational vehicles and electric motors, for example.

Specialty cordsets exist to ensure a secure, water resistant connection between the male plug and the female receptacle. However, these specialty cordsets typically include a unique, specifically designed male and female attachment to mate the two cords together. For instance, the common two- or three-prong plug that would be found on a 120 volt device for plugging into a standard wall outlet typically cannot be used in conjunction with the specialty cordsets, thereby limiting their practicality.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates an isometric view of a male plug 10 according to an embodiment of the present invention. The male plug 10 includes a generally triangular main body 12, which may be formed of plastic, connected to a collar 14, which in turn connects to an insulated electrical cord (not shown). The main body 12 may be triangular to facilitate standard electrical outlets and connections. The main body 12 may be molded from, and/or coated with, insulated plastic. Optionally, the main body 12 may be integrally formed with and connected to an insulated electrical cord. In short, the collar 14 shown in FIG. 1 may be an end of an insulated electrical cord.

A connecting interface 16 is distally located from the collar 14 at an opposite end of the collar 14. An upstanding rim 17 circumscribes the connecting interface 16. A female receptacle is configured to mate into the connecting interface 16, as discussed below.

Two conducting spades or blades 18 and a ground pin 20 extend outwardly from the connecting interface 16. The spades 18 and the ground pin 20 are configured to mate with reciprocal openings formed in a female receptacle, as shown and discussed with respect to FIG. 2. The spades 18 and the ground pin 20 are configured to plug into any standard electrical outlet. The configuration of the male plug 10 may be adapted to a standard spade and ground pin configuration. As shown in FIG. 1, the spades 18 and the ground pin 20 meet the dimension requirements as set forth in FIG. 5-15 of the NEMA Standards Publication ANSI/NEMA WD 6-2002 for a 125 volt, 15 amp, 2 pole, 3 wire, grounding type plug. Alternatively, the male plug 10 may be adapted to various other electrical configurations, such as a 120 volt or 240 volt configuration and/or a 20 amp configuration. Optionally, the male plug 10 may not include the ground pin 20.

The male plug 10 may be a two or three wire assembly suitable for outdoor use. Typical designations for the male plug 10 include SJTW and SJTOW, among others.

Threads 22 are formed on an outer surface of the main body 12 between a middle portion 23 and the connecting interface 16. As shown in FIG. 1, the threads 22 do not extend over an entire outer perimeter of the main body 12. Instead, the threads 22 are formed at apexes or corners 24 of the main body 12. Optionally, the threads 22 may extend over the entire outer perimeter of the main body 12. Moreover, the threads 22 may be formed from the collar 14 to the connecting interface 16.

FIG. 2 illustrates an isometric view of a female receptacle 26 according to an embodiment of the present invention. The female receptacle 26 may be connected to the male plug 10 (shown in FIG. 1) through an insulated cord 28, thereby forming an extension cordset. Thus, a male plug 10 of one extension cordset may be mated with a female receptacle 26 of another extension cordset. Moreover, the female receptacle 26 may be mated with a male plug of an electrical device, such as a power tool.

The female receptacle 26 includes a generally triangular main body 30 connected to the insulated electrical cord 28. The main body 30 may be formed of, and/or coated with, insulated plastic and includes a connecting interface 32 at an end opposite of the cord 28.

A ground pin mating hole 34 is formed through the connecting interface 32 and is configured to receive the ground pin 20 of the male plug 10 (shown in FIG. 1). A circular rim or tube 35 outwardly extends from the connecting interface 32 and surrounds the ground pin mating hole 34. Similarly, two spade mating holes 36 are formed through the connecting interface 32 and are configured to receive the spades 18 (shown in FIG. 1). Rectangular rims or walls 37 extend outwardly from the connecting interface 32 and surround the spade mating holes 36. The mating holes 34 and 36 may be configured the same as those found on a common electrical outlet and are configured to accept the electrical spades 18 and the ground pin 20 of the male plug 10 (shown in FIG. 1), as well as two-prong plugs that are polarized or un-polarized.

Shelves 38 are formed at apexes 40 of the main body 30. Optionally, the shelves 38 may extend around an entirety of the main body 30. The shelves 38 are configured to ensure that a connecting nut rotatably secures to the female receptacle 26, as discussed below.

FIG. 3 illustrates an isometric view of a sealing gasket 42 according to an embodiment of the present invention. The sealing gasket 42 may be formed of a material that is softer than the main body 30 of the female receptacle 26. For instance, the gasket 42 may be formed of an elastomeric or foam material that is compressible and moisture resistant.

A circular grounding rim opening 44 is formed through the gasket 42. Additionally, rectangular spade rim openings 46 are formed through the gasket 42. The grounding rim opening 44 and the spade rim openings 46 are configured to receive the circular rim 35 and the rectangular rims 37, respectively (shown in FIG. 2). When the gasket 42 is positioned over the connecting interface 32, the exposed ends of the rims 35 and 37 are flush with the exposed surface 48 of the gasket 42. Further, when the male plug 10 (shown in FIG. 1) is mated with the female receptacle 26, the gasket 42 is bounded by the rim 17 (shown in FIG. 1) of the male plug 10 and is compressively sandwiched between the connecting interface 16 (shown in FIG. 1) of the male plug 10 and the connecting interface 32 of the female receptacle 26. As such, the gasket 42 provides a water-resistant seal between the connecting interfaces 16 and 32.

The gasket may be various other shapes and sizes that those shown in FIG. 3. For example, the gasket may be shaped as a ring or outer loop of material with a central opening. As such, the outer loop is configured to contact a connection interface, such as an upturned plug lip. The gasket may also be an O-ring configured to be retained within a groove formed in the plug and/or the receptacle.

While the gasket 42 is described above as attaching to the connecting interface 32 of the female receptacle 26, the plug 10 may be alternatively configured to include rims around portions of the spades 18 and ground pin 20. In this way, the gasket 42 may be attached to the plug 10. In this arrangement, the female receptacle 26 may not include the rims 35 and 37, but may include an upstanding rim surrounding the connecting interface 32.

FIG. 4 illustrates an isometric view of a connecting nut 50 according to an embodiment of the present invention. The nut 50 includes a generally cylindrical wall 52 defining an interior passage 54. An interior surface 56 of the wall 52 is threaded 57 at one end 58. Ribs 60 outwardly extend from an outer surface 62 of the wall 52 proximate another end 64. The ribs 60 provide structures for a user to easily grasp so that the user may rotate the nut 50 when it is connected to the female receptacle 26 (shown in FIG. 2).

Referring to FIGS. 2 and 4, the nut 50 is positioned on the female receptacle 26 so that the main body 30 is positioned within the interior passage 54. That is, the nut 50 surrounds the main body 30 while exposing the connecting interface 32. The shelves 38 formed at the apexes 40 of the main body 30 abut into the interior surface 56 of the cylindrical wall 52 of the nut 50, thereby preventing the nut 50 from separating from the female receptacle 26. For example, a ledge 66 may extend from the interior surface 56 and into the interior passage 54. If the nut 50 axially shifts with respect to the female receptacle 26, the ledge 66 is blocked from further movement by the shelves 38. While the shelves 38 prevent the nut 50 from slipping off the female receptacle 26, the nut 50 is otherwise free to rotate about the main body 30 of the female receptacle 26.

FIG. 5 illustrates a simplified, partial cross-sectional view of the connecting nut 50 secured to the female receptacle 26 according to an embodiment of the present invention. A second, thinner nut 70 may be tightened against the connecting nut 50 to prevent the nut 50 from loosening during operation.

The nut 70 includes a smaller opening or interior passage 71 than that of the nut 50. As shown in FIG. 5, the nut 70 is configured to threadably engage threads 72 formed around a recessed portion of the main body 30. As the nut 70 is urged in the direction of arrow A, the nut 50 also moves in the same direction, thereby moving the threads 57 away from the main body 30 in the direction of arrow A. The nut 70 then threadably engages the threads 72 in order to secure the nut 70 to the female receptacle 26, thereby preventing the nut 50 from retreating in the direction of arrow A′.

The female receptacle 26 may also include a backstop 74 behind the nut 70 that prevents the nut 70 from slipping off the female receptacle 26. As shown in FIG. 5, the diameter of the backstop 74 is greater than the opening 71 formed through the nut 70. As such, the backstop 74 provides a stop that prevents the nut 70 from slipping past in the direction of arrow A′.

Once the nut 70 threadably engages and securely tightens to the female receptacle 26, the nut 50 is free to rotate about the female receptacle 26, but is prevented from retreating in the direction of arrow A′. In this position, the nut 50 may threadably secure to the male plug 10 shown in FIG. 1.

Referring to FIGS. 1-5, the nut 50 secures to the male plug 10 by the threads 57 engaging the threads 22 of the male plug 10. Once securely tightened, the nut 50 ensures that the male plug 10 is securely connected to the female receptacle 26. That is, the nut 50 is tightened around the male plug 10 to prevent the male plug 10 from disconnecting from the female receptacle 26. Further, as the nut 50 threadably engages the male plug 10, the gasket 42 is compressively sandwiched between the connecting interfaces 16 and 32 of the male plug 10 and the female receptacle 26, respectively, thereby providing a secure, water-resistant connection between the male plug 10 and the female receptacle 26.

FIG. 6 illustrates an isometric front view of a gasket 80 according to an embodiment of the present invention. FIG. 7 illustrates a cross-sectional view of the gasket 80 through line 7-7 of FIG. 6. As shown in FIGS. 6 and 7, a raised ridge 82 is formed around a periphery of the gasket 80. The gasket 80 may be used with the male plug 10 and the female receptacle 26 shown and described in FIGS. 1 and 2. In this case, the male plug 10 may not include the raised rim 17 (shown in FIG. 1) circumscribing the connecting interface 16 (shown in FIG. 1). Instead, the raised ridge 82 compresses between the connecting interfaces 16 and 32 and may provide a suitable seal between the male plug 10 and the female receptacle 26. However, the raised rim 17 may be used to provide additional sealing.

FIG. 8 illustrates an isometric front view of a gasket 90 according to an embodiment of the present invention. FIG. 9 illustrates a cross-sectional view of the gasket 90 through line 9-9 of FIG. 8. As shown in FIGS. 8 and 9, the gasket 90 includes a raised rim 92 around a ground pin opening 94 and raised rims 96 about spade openings 98. The gasket 90 may be used with flat faced plugs and receptacles. The raised rims 92 and 96 form seals between connecting interfaces around each individual pin and spade, respectively. The area of the gasket 90 immediately surrounding each pin and spade may be thicker than the edge of the gasket 90 so as to form a positive seal around each pin and spade.

As noted above, a male plug is connected to a female receptacle through an insulated cord to form an extension cordset. The male plug of one extension cordset may be mated with a female receptacle of another extension cordset. The male plug can also be plugged into a standard outlet to provide power to a particular device. Likewise, a device without a threaded plug may be inserted into a female receptacle of the extension cordset just like a standard extension cordset. Additionally, individual cordsets may be locked together to form longer extensions.

As discussed above, various embodiments of the present invention include a sealing gasket. Alternatively, the plug and receptacle may be formed such that their connecting interfaces are formed may be formed of a material that is softer than their respective main bodies. For example, the connecting interfaces may be formed of an elastomeric or foam material that is compressible and moisture resistant. Thus, a separate and distinct gasket may not be needed with respect to these alternative embodiments. However, the gaskets described above allow standard plugs and receptacles to be retrofit to provide moisture resistance.

Thus, embodiments of the present invention provide an extension cordset that provides secure, water-resistant connections between male plugs and female receptacles. Additionally, embodiments of the present invention may be used with standard plugs, outlets and receptacle configurations.

While various spatial terms, such as upper, bottom, lower, mid, lateral, horizontal, vertical, and the like may used to describe embodiments of the present invention, it is understood that such terms are merely used with respect to the orientations shown in the drawings. The orientations may be inverted, rotated, or otherwise changed, such that an upper portion is a lower portion, and vice versa, horizontal becomes vertical, and the like.

While the invention has been described with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from its scope. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
