FIELD

[0002] The described embodiments relate generally to electronic connectors. More

particularly, the present embodiments relate to AC plug connectors used for coupling an electronic device to the AC power grid.

BACKGROUND

[0003] Currently there arc a wide variety of electronic plug connectors that enable an electronic device to be coupled to the AC power grid. Often, such plug connectors are polarized, allowing them to male with a receptacle connector in only one orientation. However, it can be difficult to discern the proper orientation of the plug connector when attempting to mate it with a receptacle connector. In many circumstances it can also be difficult to see the receptacle connector, especially when it is positioned behind furniture or is in a recessed location. New plug connectors with features that enable a user to discern the proper orientation of the plug connector and location of a receptacle connector are needed. SUMMARY

[0004] In some embodiments an orientation device for an AC plug comprises a cover configured to be attached to the AC plug and including one or more orientation features positioned on a top surface of the cover. In various embodiments the cover is formed in a shape of a clip defining a channel.

DETAILED DESCRIPTION

[0037] Techniques disclosed herein relate generally to electronic plug connectors. More specifically, techniques disclosed herein relate to orientation features that are used to properly orient alternating current (AC) plug connectors before mating them with a corresponding receptacle connector that couples the plug to the AC grid. Various inventive embodiments are described herein, including methods, processes, systems, devices, and the like.

[0019] FIG.1 illustrates a simplified isometric view of a polarized AC plug 100 and an associated cover 110 that is configured to be secured to the AC plug. As shown in FIG. 1, in this embodiment cover 1 10 is configured to be snapped on to plug 100 via channel 1 15. Cover 105 includes one or more orientation features 120 such that when a user grasps plug assembly 125 that includes plug 100 and cover 105, the orientation features enable the user to determine a proper orientation of polarized AC plug prongs 130a, 130b and insert the plug with the correct orientation into an AC receptacle connector.

[0020] FIG. 2 illustrates a simplified isometric view of plug assembly 125 illustrated in FIG. I with cover 105 secured to plug 100. As shown in FIG. 2, cover 105 fits on AC plug 100 such that orientation features 120 are in an upward orientation when prongs 130a, 130b are in a proper orientation (c.g., polarization) to be received by a receptacle connector. In this particular embodiment, orientation features 120 include a plurality of raised features however in other s n Fo bdmn embodiments diferent orientat e

ion featur ca be empl oyed.

r example in one emoiet only a single orientation feature can be used on a top surface 140 of cover 105 (e.g., a single bump or depression), however in another embodiment a plurality of braille-based bumps can be used to inform a vision impaired person that the plug is oriented properly. In another

embodiment the use of raised alphabetic letters or words can be used to indicate orientation such as, but not limited to“UP” or“TOP”. A logo, arrow or other symbol can be used and may be raised or may be a depression. In other embodiments any feature that can be felt, or seen by a user can be used to identify the top of plug assembly 125 so plug 100 can be oriented properly during insertion into an AC receptacle. One of ordinary skill, w ith the benefi t of this disclosure, would recognize many variations, modifications, and alternatives. [0014] As further shown in FIG. 1, channel 1 15 can enable cover 105 to be fit over cord portion 145 of plug 100 and can also enable flexure of the cover such that it can be fit around the plug and be secured in place. In some embodiments cover 105 includes a top wall 160 including one or more orientation features 120 that protrude from top surface 140 of the top wall. First and scond sieall 155a, 155b, repecttiey , t

extend fromo wal 10 in a sustantially

perpendicular orientation relative to the top wall. First and second retainer walls 165a, 165b, respectively, extend from the first and second sidewalls 155a, 155b, respectively, in a

substantially perpendicular orientation relative to the first and second sidewalls such that the cover has a substantially“C” shaped cross-section or profile.

[0021] In some embodiments cover 105 can be designed for a particular“standardized” plug

100 design, while in other embodiments it may be universal to work with numerous different plug configurations. In yet further embodiments cover 105 may be secured to plug 105 using an adhesive, a fastener or any other suitable means to secure the cover to the plug. In some embodiments a retention aperture 150 can be used to allow a portion of plug connector 100 to fit within the aperture and secure cover 105 to the plug connector. One of ordinary skill, with the benefit of this disclosure, would recognize many variations, modifications, and alternatives. In one embodiment plug 100 meets the specification of the National Electrical Manufacturers Association (NEMA) 1-15 having a defined polarization, however any plug can be used including, but not limited to the“europlug” CEE 7/4 (Germany), CEE7/5 (French), NEMA (US), AS/NZS31 12 (Australian/new Zealand), NBR 14136 (Brazilian), BS546 (British), BS1363 (British) or GB2099.1-2008 and GB 1002-2008 (China). In other embodiments cover 105 can be configured to fit other types of electrical connectors, such as, but not limited to a universal serial bus (USB) connector.

[0022] In some embodiments instead of orientation feature 120 being secured to plug 100 using cover 105, the orientation features can be formed directly into a body 155 of the plug 100. More specifically, in some embodiments plug body 155 can include orientation features 120 formed from a portion of the plug body.

[0023] In some embodiments cover 1 15 can be formed from various different colors and designs that can be used to identify a particular plug that may correspond to a particular electronic device. For example in situations with many plug connectors, cover 105 can be formed using different colors such that only cords with, for example, red covers are associated with lighting devices and only cords with, for example yellow covers arc associated with acoustic devices. In this way, not only does cover 105 provide proper orientation for plug 100, but the cover associates a particular plug with a particular electronic device. In yet further embodients, cover 15 can hae different orientation feaure tha can be assocated wih a particular device. In one example a braille-type orientation feature 120 can indicate to a user that the plug is for a television, and a different cover with a different braille-type orientation feature can indicate to a user that the plug is for a stereo. One of ordinary skill, with the benefit of this disclosure, would recognize many variations, modifications, and alternatives.

[0024] In some embodiments cover 105 can be made from a flexible plastic material, however in other embodiments it can be made from any organic or metallic material.

[0025] FIG. 3 illustrates a top view of cover 105 installed on plug 100. As shown in FIG. 3, orientation features 120 can be positioned on a top surface 140 of cover 105.

[0026] FIG. 4 illustrates a side view of cover 105 installed on plug 100. As shown in FIG. 4, orientation features 120 can be positioned on top surface 140 of cover 105 and can protrude above the top surface so they can be felt by a user.

[0027] FIG. 5 illustrates a simplified isometric view of a plug connector 500 with an orientation insert 505, according to embodiments of the disclosure. As shown in FIG. 5, plug 500 includes a cavity 510 that is configured to receive insert 505. FIG. 6 illustrates a simplified isometric view of plug assembly 600 that includes plug 500 with insert 505 received within cavity 510. In some embodiments insert 505 can include one or more orientation features 520 so that by touch a user can determine an orientation of the polarized AC plug 500 and insert it with the correct orientation into an AC receptacle connector.

[0028] In addition, orientation insert 505 can include circuitry, an eneigy storage device, a light and/or a switch (not shown in FIGS. 5 or 6) so that a person can activate the switch and illuminate a region in front of plug 500 so they can see the receptacle connector when it is in a dar k location. More specif ically, orientation insert 505 can be equipped with a lighted region

525 that is directed towards prongs 130a, 130b such that light emitted from the lighted region will illuminate an designated receptacle connector. In some embodiments the switch that controls lighted region 525 can be a pressure sensitive switch disposed under orientation feature 520. In further embodiments the energy storage device can be electrically coupled to AC plug 500 such that when the AC plug is receiving power from a receptacle connector the energy storage device is charged. In another embodiment wireless charging can be used to charge the energy storage devce .Wen AC plu assembl 60 is unpggd from th recepale connector the light can use energy from the energy storage device. In one embodiment the light is an LED while in another embodiment it is a glow-discharge device and in another embodiment is an incandescent light In one embodiment the energy storage device is a rechargeable battery an in another embodiment it is a capacitor or other type of energy storage device.

[0029] Orientation insert 505 can be secured within recess using one or more snap features or any type of adhesive or fastener. Orientation insert 505 can be equipped with one or more electrical couplers (not shown) that couple to prongs 130a, 130b and/or electrical conductors 530 within plug 500 to provide electrical power to the circuitry within the orientation insert. In some embodiments, orientation insert 505 can be made from different materials with a relatively soft plastic forming the top portion that deflects under pressure to operate the switch and the remaining portion made out of a relatively harder plastic to be secured to AC plug 500.

[0030] Although a United States standard AC plug 500 is illustrated, one of skill in the art can appreciate that other types of electrical plugs can benefit from similar orientation inserts, some of which are described herein with regard to FIGS. 1-4. In further embodiments orientation insert 505 may not be an insert and may be integrally formed with plug 500 body.

[0031] FIG. 7 illustrates a top view of orientation insert 505 installed in plug 500. As shown in FIG. 7 orientation features 520 can be positioned on a top surface 540 of cover.

[0032] FIG. 8 illustrates a side view of orientation insert 505 installed in plug 500. As shown in FIG. 8 orientation features 520 can be positioned on a top surface 540 of orientation insert 505 and can protrude above the top surface so they can be felt by a user.

[0033] In the foregoing specification, embodiments of the disclosure have been described with reference to numerous secific detail that can vary from implementation to implementation.
