(13) FIGS. 1-3 depict perspective, side, and frontal views of an AC inlet/outlet assembly 100, according to an embodiment of the invention. In an embodiment, assembly 100 houses an AC (female) outlet 110 and an AC (male) inlet 120 coupled together in a water-sealed fashion within a single body. The assembly 100 includes a front face 102 including slots 112, 114, 116 that house the respective line, neutral, and ground terminals of the AC outlet 110. In an embodiment, the slots 112, 114 and 116 may include a seal such around each of the terminals of the AC outlet 110 to avoid water leakage through the slots 112, 114 and 116. The front face 102 also includes a recessed portion 104 formed by a series of side walls 106 and a rear wall 107 formed around the AC inlet 120 terminals (i.e., line, neutral and ground terminals 122, 124 and 126). In an embodiment, the rear wall 107 may be insert-molded around the terminals 122, 124 and 126 to avoid water leakage to the rear side of the real wall 107.

(14) In an embodiment, the AC outlet 110 and AC inlet 120 terminals are arranged to be a mirror image of one another, as shown in FIG. 3. In the illustrative example, the ground terminals are arranged on the outside.

(15) In an embodiment, the assembly 100 further includes a rear main body 130 that includes channels and structure to electrically connect corresponding terminals of the AC outlet 110 and AC inlet 120, as described herein in detail.

(16) FIG. 4 depicts a front cross-sectional view of the AC inlet/outlet assembly 100 showing the internal components for connecting the AC outlet 110 and AC inlet 120. FIG. 5 depicts a rear perspective exploded view of the AC inlet/outlet assembly 100 including the internal components of the main body 130 in an exploded form, according to an embodiment.

(17) As shown in these figures, in an embodiment, the main body 130 includes a series of lateral walls 132, 134 projecting rearwardly from the rear face 103 opposite the front face 102. The walls 132, 134 form first, second and third channels 140, 142, and 144 between the line, neutral, and ground terminals (not shown) of the AC outlet 110 and the line, neutral, and ground terminals 122, 124 and 126 of the AC inlet 120. These channels 140, 142, and 144 extend laterally from the rear face 103 and are separated from one another via lateral walls 132 and 134. In an embodiment, the three channels 140, 142 and 144 are arranged in parallel along a plane that is parallel to a plane of the front face 102 of the inlet/outlet assembly 100.

(18) In an embodiment, the main body 130 further includes a series of first, second, and third connectors 150, 152, 154 received within respective channels 140, 142, and 144. Each connector 150, 152, 154 includes an elongated metallic body, ends of which electrically connects with the line, neutral, and ground terminals (not shown) of the AC outlet 110 and the line, neutral, and ground terminals 122, 124 and 126 of the AC inlet 120. In an embodiment, each connector 150, 152, 154 includes a lateral receptacle tabs 156, 157, and 158 that received the ends of the line, neutral, and ground terminals (not shown) of the AC outlet 110 therein.

(19) In an embodiment, the main body 130 further includes a gasket 160 and a cover 170. The gasket 160, in an embodiment, includes the same profile as the walls 132 and 134, and is disposed between the ends of the walls 132 and 134 and the cover 170 to form a water-seal coupling. The cover 170 and the gasket 160 together fully seal the channels 140, 142, and 144 to block any fluid communication between the channels 140, 142, and 144, and from the outside environment. In an embodiment, the cover 170 is fastened to the main body 130 via screws.

(20) In an embodiment, as shown in FIG. 6, additional line, neutral, and ground terminals 180, 182, 184 are coupled to the connectors 150, 152, 154 through the cover 170. One the assembly 100 is mounted on a device such as a light, a vacuum device, etc., the terminals 180, 182, 184 allow for electric connectivity of the device to the AC outlet 110 and AC inlet 120. In an embodiment, the cover 170 may be insert-molded or otherwise sealed outside the periphery of the terminals 180, 182, 184.

(21) FIGS. 7 and 8 depict perspective and top cross-sectional views an AC inlet/outlet assembly 200, according to an alternative embodiment. In this embodiment, the AC inlet 210 and AC outlet 220 are arranged at an angle (e.g. greater than 90 degrees and smaller than 180 degrees) with respect to one another. A series of lateral sealed channels (not shown) are formed between the corresponding line, neutral, and ground terminals of the inlet 210 and outlet 220. Because the inlet 210 and outlet 220 are arranged at an angle, corresponding terminals need not be arranged in mirror image of one another. In an embodiment, the channels may be disposed in sequence along a plane that is perpendicular to a plane of a front face 202 of the inlet/outlet assembly 200.

(22) FIG. 9 depicts a perspective view of an exemplary lighting device 300 employing an exemplary AC inlet/outlet assembly, according to an embodiment of the invention.

(23) In an embodiment, the lighting device 300 includes a main body 310 and a head portion 320 accommodating at least one Light Emitting Diode (LED) (not shown).

(24) In an embodiment, the main body 310 includes a substantially square-shaped or circular base 312 and a cubical or cylindrical body 314. Four vertical side handles 316 are disposed around the main body 110. The main body 310 includes a control interface 330 for receiving control commands from a user. The control interface 330 includes push-buttons and/or other control mechanism for turning the lighting device ON and OFF, mode selection, etc. Mode selection, in an embodiment, correlates to the amount of light output (i.e., brightness) of the LED. In an embodiment, main body 310 also includes the AC inlet/outlet assembly 340, constructed according to any of the above-described embodiments, for receiving AC power from an AC power supply and supplying AC power to another electrical device such as a lighting device.
