DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Various exemplary embodiments relate to a pop-up electrical outlet having, for example, a cylindrical profile. The pop-up outlet can be recessed in a surface, for example a countertop, and raised and lowered as needed. The outlet can be raised and lowered manually, using a biasing mechanism, through a motor and gear assembly, or through another suitable mechanism.

FIGS. 1 and 2 show an exemplary embodiment of a pop-up outlet 10, having an upper portion including an outlet housing 12, a middle portion including a terminal housing 14, and a lower portion including a wiring housing 16. The outlet housing 12 includes a cavity or chamber for receiving at least a portion of an outlet, the terminal housing 14 includes a cavity or chamber for receiving at least a portion of a terminal device and conductors extending from the terminal device to the outlet, and the wiring housing 16 includes a cavity or chamber for receiving at least a portion of wiring extending from an external source into the pop-outlet.

A raise/lower mechanism 18 extends through the terminal chamber to raise and lower the outlet housing 12 with respect to the terminal housing 14. The raise/lower mechanism 18 includes a translating 20 member that moves between an extended position (as shown) and a retracted position (not shown). The raise/lower mechanism 18 can be completely manual, include a biasing member, or include automated components such as a motor, threads, gears, telescopic members or other components as would be understood by one of ordinary skill in the art.

In various exemplary embodiments, the outlet and a platform 24 are positioned in the outlet housing 12 and a cover 26 is releasably connected to the outlet housing 12, for example through a snap-fit connection. As shown in FIGS. 4-6, the outlet housing 12 includes a first snap-fit connection member and the cover 26 includes a second snap-fit connection member configured to mate with the first snap fit connection member. In an exemplary embodiment, the outlet housing 12 includes first and second openings having a resilient tab 28. The cover 26 includes first and second protrusions 30 that snap-fit into the openings. The protrusions 30 can be cantilever beam having a catch or hook member. The cover 26 can also include one or more posts 32 extending into the outlet housing 12.

The outlet includes an outlet body 34 that is connected to the platform 24, for example through a snap-fit connection. The platform 24 can include one or more openings with a resilient tab that respectively receives one or more flexible prongs from the outlet body. The outlet includes openings for receiving a plug or other type of connector. A three-prong opening having, hot, neutral, and ground receptacles are shown, although the outlet can include a two-prong outlet, a USB outlet, or any other type of electrical connector outlet as would be understood by one of ordinary skill in the art. The outlet will include various other internal components as would be understood by one of ordinary skill in the art.

According to various exemplary embodiments, a gasket or seal 36 is positioned around the outlet body 34 to resist or prevent liquids from entering the outlet body 34 and negatively impacting the electrical components of the outlet. FIGS. 7 and 8 show and exemplary embodiment of the seal 36. The seal 36 covers the front, back, sides and top of the outlet body 34. The seal 36 can include openings or slits (not shown) positioned and sized to align and match the connector openings of the outlet. The slits can be resiliently biased to a closed position, but capable of moving to receive a connector, for example the prongs of a plug.

The terminal chamber includes an upper portion for receiving the outlet housing 12 in the retracted position. An upper plate 38 is connected to the terminal housing 14 and an upper flange 40 is releasably connected to the upper plate 38. As shown in FIGS. 4-6, the upper plate 38 includes a first snap-fit connection member and the flange 40 includes a second snap-fit connection member configured to mate with the first snap fit connection member. In an exemplary embodiment, the flange 40 includes a set of four protrusions 42 that snap-fit into the openings. The protrusions 42 can be cantilever beam having a catch or hook member. The flange 40 can also include one or more posts 44.

An outer surface of the terminal housing includes an outer thread 46. A ring 48 having an inner thread is threadably connected to the outer thread 46. The pop-up outlet 10 can be positioned in a support, such as a countertop, with the flange 40 engaging a top surface. The ring 48 is adjusted and tightened to engage the bottom surface. Adjusting the ring 48 allows the device to be installed in supports having different depths. The ring 48 includes a gasket to create a seal between the ring and the bottom surface of the support.

A terminal block 50 is positioned in the pop-up outlet 10 with a top portion in communication with the terminal chamber and a bottom portion in communication with the wiring chamber. One or more conductors 52 extend from the terminal block 50 to the outlet body 34 to electrically connect the outlet with a power supply.

As best shown in FIGS. 9 and 10, the top portion of the terminal block 50 includes a set of openings 54, for example a hot opening, a neutral openings, and a ground opening. The openings are positioned near strain relief members 56. Conductors 52 can extend through the openings 54 and be received in the strain relief members 56. The strain relief members 56 reduce or eliminate strain on the conductors as the outlet is raised and lowered, helping to prevent disconnection of the conductors.

In an exemplary embodiment, the strain relief members include a base 56 and a releasable clip 58. The base 56 includes a channel for receiving the conductors a set of side projections or barbs. The clips 58 include a pair of side openings that receive the barbs in a snap-fit connection.

As best shown in FIG. 11, the lower portion of the terminal block 50 includes a set of wiring terminals, for example a hot, neutral, and ground wiring terminal. The wiring terminals can include an opening 60 positioned orthogonal to a fastener 62, such as a screw, and a moveable plate for clamping an exposed end of a conductor that is inserted into the opening 60. Different types of connections, including crimps and other fasteners can also be used.

As best shown in FIG. 2, the wiring housing includes different passages for receiving different types of power supply conductors or conduits. For example, a knock-out 64 is provided to receive a metallic cable or conduit. A strain relief member 66 having a pair of fasteners and a moveable strain relief plate can be provided for non-metallic cables.
