Background Technology

[0004] Traditional techniques for installing electrical components and appliances such as lighting fixtures and fans on walls or ceilings typically require the assistance of a qualified electrician, as well as the use of various tools and specialized hardware. Even when performed by experienced installers, the process of installing or removing such components can be relatively time-consuming. In addition to the necessary electrical connections between the components and the power wiring that need to be manually connected, installers must also make separate mechanical connections to support or suspend the components in place.

[0005] The patents identified in the cross-references to related applications disclose solutions to these and other problems. These related patents and applications disclose various embodiments of plug and socket combinations that allow for quick connection of electrical components or appliances at electrical junction boxes on walls or ceilings. The socket is fixed to a wall or ceiling near the power supply wiring and includes a female socket that receives a plug with male prongs. The electrical component is fixed to the plug. In addition to the quick electrical connection provided by this plug and socket combination, the mechanical connection between the plug and socket also bears the mechanical load of the electrical component.

[0006] This disclosure describes improvements related to various embodiments of plug and socket combinations in cross-references to related applications for use when recessed lighting is required. Recessed lighting systems utilizing plug and socket combinations are also disclosed.

[0007] Recessed lighting is a versatile tool that provides ambient and task lighting for any area in a home, office, or any desired space. These lights, also known as spotlights, can lights, or socket lights, are installed within a ceiling or wall (usually within a ceiling) rather than being surface-mounted on a wall or ceiling.

[0008] Recessed lighting consists of two main components—the housing and the trim, both of which are optional (and usually sold separately). The housing sits above the ceiling and contains all the electrical components, such as the light source and the tools for mounting. The trim refers to what we see below the ceiling, such as trim styles or light guide sections.

[0009] Beyond the functional differences among the various recessed lighting options available on the market, there are also aesthetic differences. If the appearance of a round, white device is not appealing for a given application, there are other options. Recessed lights with decorative rings in different colors or metallic finishes are available. If round styles are too simple or traditional, square lights, as well as lights of different shapes and sizes, can be used. Summary of the Invention

[0052] This disclosure relates to the inventors’ prior work, such as that described in the documents identified in the cross-reference sections of the related applications, the contents of each of which are incorporated herein by reference in their entirety. In this regard, plugs and / or sockets may include sensing units for wirelessly transmitting at least one of sensed conditions and wirelessly received signals, as disclosed in PCT International Patent Application No. PCT / US2016 / 032170, filed May 12, 2016, and PCT International Patent Application No. PCT / US2018 / 020987, filed March 5, 2018.

[0053] "Quick-connect devices" for installing electrical components consist of a combination of a plug and a matching receptacle. The plug and receptacle of this device both establish an electrical connection between the electrical component and the power supply wiring, and provide mechanical support for the component on a surface or base (typically a wall, ceiling, or floor surface). As used herein, the term "component" or "electrical component" refers to any device or appliance, such as a lighting fixture, ceiling fan, television camera, security equipment, or any other device powered by an electrical circuit, and any other device that requires a mechanical connection to support or suspend the component. The plug is fixed to the electrical component, while the receptacle is fixed to the surface (such as a wall, ceiling, or floor) or electrical junction box where the component is to be mounted. The construction, function, and operation of plugs and receptacles are generally described in detail in the patents and applications cited herein.

[0054] For example, the combined references to WO 2016 / 183354 A1 and WO 2018 / 165058 A1 (collectively, the “Smart Quick Connect Publication”) describe a quick-connect device 22 for mounting electrical components, comprising a plug 30 and a mating receptacle 20. Detailed descriptions of the structure and function of the receptacle 20, plug 30, and spindle assembly 24 are provided in the Smart Quick Connect Publication and other combined references. In the Smart Quick Connect Publication, one or more sensors or other receiving / input or transmitting / output electronic or electrical devices 48, 50 (hereinafter referred to as “sensors”) may be associated with the plug 30 or receptacle 20. The receptacle 20 is known as disclosed in the combined references and is incorporated into the U.S. National Electrical Code.

[0055] As detailed in the Smart Quick Connect disclosure and elsewhere herein, the devices disclosed herein may be equipped with or attached to electronic sensors and / or processors, transmitters and / or receivers, and other electronic circuitry, and may be considered “smart” devices. Alternatively, the devices disclosed herein may be associated with power-consuming devices (such as lights or fans) and may or may not include “smart” electronic devices or components, or other electronic devices unrelated to the operation of the device itself.

[0056] plugs and sockets

[0057] Figure 1 An exemplary conventional socket 20 is shown. The conventional socket 20 can be used as a socket that forms part of a quick-connect device according to this disclosure. Figure 2 A conventional plug 30 is shown, which has the same features as a plug that forms part of a quick-connect device according to the present disclosure. Figure 3 An alternative spindle assembly 24A is shown. The socket 20, plug 30, and alternative spindle assembly 24A are now discussed to help describe some of the structure, function, and operation of the quick-connect device according to this disclosure.

[0058] In particular, the socket 20 of the conventional quick-connect device 22 for installing electrical components receives the plug 30, thereby forming an electrical connection between the socket 20 and the plug 30. Figure 1 In this configuration, socket 20 can be attached to a bracket 36 or other structure designed for mounting in a standard electrical box or building. For example... Figures 2-5As shown in Figure 7, the spindle assembly 24 is used to mechanically connect the plug 30 to the socket 20 in a releasable manner. A male connector ring 32 is provided within the cavity 138 of the plug 30, which, if the body 26 of the plug 30 is molded from a non-conductive material, can be supported by integral molding. Sufficient radial spacing exists between the rings 32 to electrically insulate them from each other. The diameter and spacing of the male connector rings are such that they align with corresponding female recesses 34 in the socket 20 and can receive corresponding female recesses 34 within the male connector ring to make electrical contact with mating receptacle conductors 38 within the socket 20. As detailed in the patent publication incorporated by reference, this alignment is used to electrically connect the plug 30 to the socket 20, thereby establishing an electrical connection between the electrical device and the power supply wiring, and mechanically supporting the device on a surface or base, typically a wall, ceiling, or floor surface.

[0059] The number of loops can correspond to the number of electrical connections required. For example, a power connection may include a source or "hot" conductor protected by a circuit breaker, a loop or "neutral" conductor, and a safety or "ground" conductor. Additional conductors can be added for three-way switch leads or moving conductors, a second "hot" conductor can be added for a two-phase connection, and any number of signal conductors can be added for analog or digital data.

[0060] Figure 3 An alternative spindle 24A is shown, in which one or more balls 72 are radially oriented 90 degrees relative to other balls 72 spaced apart axially along the spindle 24A. General purpose Figure 2 and Figure 3 In two embodiments, spring 76 (as shown) Figure 3 (As shown) This biases the locking pin 74, which slides within the sleeve 70 / 70A, positioning the groove 78 of the locking pin 74 away from the ball 72. This keeps the ball 72 engaged within and extending from the hole 114 in the sleeve 70, thereby preventing it from being damaged by the matching groove or crossbar 66 in the sleeve 68 fixed to the socket 20. Figure 7 Interference between the sleeve 70 and the socket 20 causes the sleeve 70 to be withdrawn from the sleeve 68 of the socket 20. When the locking pin 74 is pushed against the bias axis of the spring 76, the locking pin 74 moves to align the groove 78 with the ball 72, thereby allowing the ball 72 to move away from the interference of the sleeve 68, so that the sleeve 70 can be withdrawn from the sleeve 68, thereby removing the plug 30 from the socket 20.

[0061] It should be understood that the choice of socket 20 as the base reflects that the conductor carrying potentially dangerous high-voltage electrical signals should be embedded and not touched by a person. However, if only low-voltage / low-power signals are used, the positions of the plug and socket can be reversed or arbitrarily selected.

[0062] Embedded plugs and sockets

[0063] refer to Figures 4-5 The socket 20 includes a generally cylindrical body 112 formed of a non-conductive material such as phenolic resin. Concentric, annular, female recesses, or grooves 34 are formed on one surface of the socket 20 and configured to matingly receive a male connector ring 32 of a plug 30 to establish an electrical connection between the plug 30 and the socket 20. The socket 20 includes a bushing 116 fixed to the socket 20, the bushing 116 defining a through-hole through which the spindle 24 can pass. In the illustrated embodiment, the bushing 116 passes through and is fixed to an elongated mounting bracket 36A by welding, riveting, threaded fasteners, or other attachments. Alternatively, the bushing 116 and the bracket 36A may be an integral structure formed from a single high-strength material, such as metal, by casting, machining, or other metalworking processes.

[0064] The bracket 36A is typically U-shaped with an extension arm 120 of a selected length, such that when the electrical equipment is installed in the electrical junction box 108, the electrical equipment containing device 20 has the appearance and effect of a recessed electrical device, such as recessed lighting. While depending on the length of the portion of the electrical equipment to be recessed or hidden, the length of the arm 120 is at least twice the height of the socket body 112. The bracket 36A has outwardly extending mounting flanges 124 located at the end of each arm 120, which extend away from each other. Each flange 124 includes a hole 122 through which the bracket 36A can be attached (e.g., via screw 110) to the junction box 108. In this way, device 20 can be attached to the junction box 108. Therefore, as... Figure 5 As shown, the U-shaped configuration of length 120 and bracket 36A allows the socket 20 to be embedded within the junction box. By selecting a specific length 120, the height within a specific type of junction box can be predetermined.

[0065] As further detailed in the merged references, the length of the extension arm 120 is adjustable. In one embodiment, the arm 120 is provided in two attachable lengths that may overlap to a greater or lesser extent. These two attachable lengths may be secured to each other, for example, using threaded fasteners. More specifically, one attachable length may have multiple spaced-apart holes, while the other attachable length may include at least one hole through which a fastener can extend through a selected spaced-apart hole, thereby determining the length of the arm 120 comprising the two attachable lengths.

[0066] The socket body 112 may have a circular notch 126 defining an annular surface 128, which is designed to engage with a corresponding surface on the plug 30 and serves as a stop to restrict the plug 30 from entering the socket 20. The plug 30 and socket 20 each have a plurality of teeth 130 on the periphery of the socket 20 and the mating periphery of the plug 30, respectively. Alternatively, the teeth 130 are provided on the surface 128 of the plug 30 and the mating surface. When the plug 30 and socket 20 are mated, the teeth 130 of the plug 30 and socket 20 engage or mate with each other to prevent relative rotation. Before the teeth 130 of the plug 104 and socket 106 engage, the plug 104 and socket 106 can rotate freely relative to each other to select a desired radial alignment between the socket 20 and the electrical equipment associated with the plug 30.

[0067] The receptacle body 112 includes connecting lugs 132, each of which has an electrical contact / connector 134 for receiving and securing power wiring, for example, via bolt-type terminals, quick-release connections, or other suitable electrical connections. The exact dimensions of the connector 134 are determined based on the maximum wire gauge required for the intended application. The exposed stripped end of the power wiring is connected to the receptacle 20 by inserting the wire end into one of the connectors 134. Each of the lugs 132 is electrically connected to a corresponding conductor 38, as disclosed in detail in the patent documents incorporated herein by reference. Although the lugs 132 are shown on the side of the body 112, in some applications it may be more convenient or possible to feed the power wiring into the rear of the receptacle body 112, where the receptacle body 112 corresponds to the upper or top surface when the junction box is mounted on the ceiling. In this case, the power wiring can be positioned via an embedded opening located at the top of the receptacle body 112, where it is also electrically connected to the receptacle conductor 38.

[0068] exist Figure 5 In the middle, device 102 is fixed on plug 30, such as Figure 5 As shown, this serves as a blank cover. When device 102 is a blank cover, it has the advantage of covering the socket 20 and providing a finished appearance when electrical device 102 may not be needed or has not yet been selected. When device 102 is a blank cover, connector ring 32 may be absent or may be made of a non-conductive material to reduce costs. To enable the release of device 102, button 150 is movably fixed within device 102 and contacts or connects to locking pin 74, thereby allowing pin 74 to be pushed to release spindle 24, as previously described. Button 150 can be pressed with a finger or tool to release blank cover 102. When device 102 is a lighting or other electrical device, it can be released in a similar manner if button 150 is accessible. When electrical device 102 covers the area of ​​button 150, a rod or other structure can be connected to locking pin 74 and extend through the device to the location where it may be pressed down to release the device.

[0069] Device 102 can be secured to plug 30 in various ways. For example, device 102 can be securely attached to the lower part of sleeve 70. As shown, device 102 includes cover 152, which is attached to the inside of sleeve 70, and device 102 is attached to cover 152. The weight of device 102 is transferred to mounting band 36A through sleeve 144, retaining ball 72, and socket sleeve 68, and mounting band 36A is secured to electrical junction box 108.

[0070] Device 102 may include a cover 152, which may be equipped with edges 154 to create a decorative appearance in conventional embedded devices. Cover 152 may be transparent plastic or glass to allow illumination from lighting device 102 to be transmitted. Cover 152 may include lenses, filters, or other optical elements to produce the desired lighting effect.

[0072] Now, specifically regarding references... Figures 6-7 The plug 30A includes a body 26 that slidably receives a release lever 148 in a channel 104. In the illustrated embodiment, the body 26 includes circumferential teeth 123 that mate with complementary teeth 130 on the socket 20 to enable setting and matching a specific radial alignment of the socket 20 and the plug 100 when the plug 100 is inserted into the socket 20.

[0073] exist Figure 6 In the first position, the lever 148 is in the first position, where the cam follower 110 moves along the cam surface 158 under the push of the elastic member, thereby increasing the contact area between the cam follower 110 and the cam surface 158. In this position, the locking pin 74 is in a lower position, such as... Figure 2 As shown, at this point, the locking pin 74 no longer positions the groove 78 near the ball 72, thereby locking the ball 72 into engagement with the sleeve 68. In this embodiment, the locking pin 74 is pushed to a first position by the pin spring 76, the first position being located between the follower 110 and the crossbar 118 within the main shaft 24. Alternatively, the spring 76 can be as follows: Figure 5 As shown in the diagram. A separate elastic member, in this embodiment a return spring, further biases the lever 148 to the first position.

[0074] Now for reference Figure 7 ,exist Figure 7 In the example, lever 148 is pushed to the right within channel 104 against the bias of return spring 106 to a second position representing the unlock / release position. As lever 148 moves to the second position, cam follower 110 slides onto cam surface 158, as... Figure 7As shown, the cam surface pushes the cam follower 110 upward, away from the operating lever 148, compressing the pin spring 76. Therefore, the locking pin 74 moves upward, aligning the groove 78 with the ball 72, allowing the ball 72 to disengage from the socket sleeve 68, thus mechanically separating the plug 30 from the socket 20. Figure 7 In this case, the follower 110 has been completely removed from engagement with the cam surface 158. However, the follower 110 and the recess 78 can be positioned so that the follower 110 can remain partially engaged with the surface 158 to align the ball 72 and the recess 78 to unlock and release the plug 100 and the socket 20.

[0075] As shown, the cam follower 110 can be formed as a separate part attached to the locking pin 74, or integrally formed at the end of the locking pin 74. The cam follower 110 can be made of any sufficiently durable and rigid material, such as metal, plastic, synthetic or composite materials, or natural materials such as wood. When attached as a separate part, the follower can be attached by interference fit and / or by adhesives, threaded connections, brazing, welding, or any other method that ensures a durable attachment. As shown, the lever 148 defines the range of motion of the follower 110, thereby limiting the position of the locking pin 74 between a first (locked) position and a second (unlocked / released) position.

[0076] The joystick 148 is slidably confined within the channel 104, and is prevented from being pushed out of the channel 104 by the force of the spring 106 or gravity, through a retaining post 144 passing through a retaining groove 146 formed within the joystick 148. The free end of the joystick 148 may have a release button 150, such as... Figure 5 As shown in the embodiments.

[0077] In the illustrated embodiment, the cam surface 158 and the follower 110 are conical in shape, but the surfaces of the cam surface 158 and the follower 110 do not need to be circumferential; they can be flat, V-shaped, or other shapes, and are positioned only along the release movement direction of the lever 102 described herein. The release lever 148, channel 104, cam surface 158, cam follower 110, and related structures include a lever release assembly.

[0078] Side-release recessed plugs and sockets

[0079] Now go to Figures 8-9 It can be seen that the joystick 148A is similar to Figures 6-7The control lever 148 includes a control lever extension 162, which positions the distal end 164 of the control lever 148A at a distance from the plug body 26. This allows the plug 30A to be inserted into the electrical junction box 108 while simultaneously enabling the control lever 148A to be operated to release the plug 30A from the socket 30.

[0080] More specifically, reference Figure 9 The plug 30A is shown schematically on the right side and is installed within the electrical component 300. The button 150 is visible on the outer flange 164. See further details. Figure 9 On the left is Figures 4-5 An embodiment of the socket 30. The electrical device 300 has a main body housing 302 sized to be installed within a junction box 108, wherein a flange 320 is located outside and covers the junction box 108. In this way, a plug 30A can be mated with the socket 30, and a button 150 can be pressed to push a rod 148A to release the device 300.

[0081] Although device 300 is described as a lighting device, it is clear that any type of device (at least partially embedded in junction box 108) can be included or formed extending from plug 30A.

[0082] Side-mounted embedded smart plugs and sockets

[0083] from Figure 9 As can be clearly seen in the schematic diagram of plug 30A, the internal space provided by the main body 202 is more than the internal space required to accommodate plug 30A. (Reference) Figure 10 The diagram shown is a cross-sectional view of one embodiment of device 300, in which a portion of the additional internal space is used to accommodate electronic components.

[0084] exist Figures 10-11 In this design, junction box 108 is installed within ceiling 200. For example, when device 300 is a recessed lighting device, the device is typically flush or nearly flush with the ceiling and covers the front of junction box 108 so that no part of junction box 108 is visible. As described elsewhere herein, socket 20 may be installed at a distance from the opening of junction box 108 to provide space for device housing 302. This further facilitates wire connections and keeps wires away from device housing 302. The circled area 324 indicates the location of cam follower 110 and cam surface 158 at a distance from housing 312.

[0085] In this embodiment, electrical device 300 includes a light source LED 322. Although the light source 322 is shown as an LED on an electronic circuit board 308, the invention contemplates the use of any suitable light-emitting device. The electronic circuit board is described herein as a printed circuit board (PCB), but any type of electronic board can be used in this invention. If there are multiple circuit boards, they are connected via suitable electrical connectors (not shown). Similarly, power from the junction box is connected as needed between plug 30A and circuit board 308, via a wire connection between electrical connector 134 and electronic circuit board 308, or via an integrated conductive path, for example, which can be embedded between them in a loop 32. Lens 314 protects LED 322 and can provide filtering, focusing, or other light-adapting functions to produce the desired lighting effect. If desired, lens holder 316 can secure lens 314 to cover 312 and / or housing 302. The circuit board 308 can be fixed to the housing 302 or the housing 312, which are fixed to the plug 30 / 30A, or it can be directly fixed to the plug 22 / 30A, for example, the plug body 26 or the spindle assembly 24 / 24A.

[0086] exist Figure 10 The diagram shows three circuit boards 308, although any number of circuit boards 308 can be provided. As seen in the diagram, the bottommost board supports and powers the LED 322. Any board can incorporate any of the various electronic devices disclosed in the combined references. Examples include devices or supporting electronic equipment that may include any or all lights; transmitters / receivers for any radio frequency, Wireless Fidelity (WiFi), Bluetooth, Near Field Switching, Inductive Charging, cellular, Low Power Wide Area Network (LPWAN), Long Term Evolution (LTE), LTE-Machine-to-Machine (LTE-M), Narrowband Internet of Things (NB-IoT), Long Range Radio (LoRa), Zigbee, Z-Wave, or other known or later-developed signal transmission; temperature, humidity, smoke, motion, thermal signals, ultrasound, sound, speakers, microphones, propane, carbon monoxide (CO), or other gas sensors; security devices such as security cameras (with or without motion detection), glass breakage detection loops (with or without self-monitoring), pressure sensors, or strain gauges. It should be understood that this is necessarily a limited list, as other types of electronic equipment may be incorporated into the devices of this invention. Figure 10The image shows a signal transmitter / receiver 310 near the cover 312 as an example. It may include a battery 324. Figure 11 This is to maintain power supply when the power is off. A charging system (not shown) for battery 324 may be provided on circuit board 308, wherein battery 324 is intended to be rechargeable. For convenience, the aforementioned devices are all referred to here as "sensors" and are generally specified by reference 48 or 50. If the sensor specified by reference 48 emits a signal or other emitter, then the sensor generally refers to a transmitter, and if the sensor specified by reference 50 receives a signal or other emitter, then the sensor generally refers to a receiver.

[0087] Figures 12-14 Three different shapes of the cover 312 for device 300 are shown, including a shallow convex cover, a raised convex cover, and a slanted cover. Since only the cover portion is visible, the decoration of device 300 can be easily altered to achieve a desired appearance. It is also evident that the shape of the release button 150 can correspond to this shape. Furthermore, it can be seen that additional internal space can be created with a greater height for the cover 312. The width of the cover 312 is just sufficient to cover the junction box 108, or it can be wider to accommodate a decorative style or create additional space. Figure 11 As shown, the flange 320 and the cover 312 have the same width and match to form a three-dimensional integral flange / cover, and together support the joystick extension 162 and the button 150.

[0088] Therefore, the cover 312 provides a decorative section designed to extend below the ceiling surface where the device is embedded. Thus, all the structures described herein can be placed above the ceiling surface, achieved through the precise length of the arm 120 and the corresponding height of the housing 302, except for the flange 320 (if present), which lies on the ceiling surface. Ultimately, when selecting a decoration for this location, the cover 312 that best complements the decoration can be chosen. The cover 312 can be further treated with paint, fabric, or printed materials for better coordination with the decoration without removing the embedded components. A button 150 that matches the selected cover 312 can be selected and secured to the end of the lever extension 162 by any known means, such as adhesive, interference fit, thread, clip, or other fastener types.

[0089] Figure 15 It shows Figure 12 The configuration of the cover 312 and the cross-sectional view of the device 330, which is similar to... Figures 10-11 The difference between device 300 and device 330 is that, since LED 322 can operate at the input voltage, device 330 does not have a circuit board 308. It can be seen that there is extra space within junction box 108, or a smaller junction box could be used. Figure 16Device 340, similar to device 330, is shown, but it shows... Figure 13 The lens cover is configured as follows. In addition to the button release provided by the joystick extension 162, a central button release is also provided. However, it may be necessary to remove the lens 314 to access the button release unless the device 340 does not include a lens cover or has a different configuration. Figure 17 A portion of device 340 is shown, but it includes... Figure 14 The configuration of the cover.

[0090] Figure 18 An embodiment of an embedded lighting system 400 is shown, which utilizes, for example... Figures 10-11 The various embodiments shown and described are electrically coordinated. Each device 300 is supported in a junction box by a bracket 36A, but the junction box 108 is not shown for clarity. The recessed lighting system 400 includes a first recessed device 300A, a second recessed device 300B, and a third recessed device 300C. Although three recessed lighting devices are shown, the system 400 may include any suitable number of devices. The first device 300A may be a so-called smart device, having one or more sensors 48 / 50, such as... Figures 10-11 As shown. In the example shown, the three lighting devices are coordinated; therefore, the sensors 48 / 50 in device 300A may include a receiver for a remote control or other control device, as well as related electronics for switching or dimming the three devices, or for changing the color of one or more devices. In this way, only device 300A requires the circuit board 308 or the sensors 48 / 50. However, devices 300B and 300C may also include these components, for the same or different purposes as device 300A.

[0091] like Figure 18 As shown, device 300A is connected to conductor "L1," which is connected to the thermal contact of line 1 or power supply, such as in building wiring. Conductor "G" is grounded relative to L1, and conductor "W" is connected to the neutral point associated with L1. Devices 300B and 300C are not connected to L1, but rather to "L2," which is controlled by device 300A. The devices emit signals on L2 corresponding to the desired lighting effects of devices 300A and 300B, which may be the same as or different from those of device 300A. The signals on L2 are modified by electronic components mounted on circuit board 308 of device 300A. It should be understood that L2 may include multiple conductors for transmitting different signals from device 300A to devices 300B and 300C.

[0092] In one embodiment, L2 represents an Ethernet or fiber optic connection and can carry IP-based or other network traffic, such as serial data. In another embodiment, L2 represents Power over Ethernet (PoE). In yet another embodiment, L2 represents separate power and data lines.

[0093] Now for reference Figure 19 The base 324 of the bracket 36B is secured to the socket 20 by any suitable means, such as threaded fasteners, rivets, moldings, pins, clips, or welding. An extension arm 120A extends from the base 324 in a direction away from the socket surface 128. The base 324 has a selected width to position the extension arm 120A near the inner surface of the opposite side 326 of the junction box 108. Furthermore, the extension arm includes a channel 328 sized to allow the passage of the box screw lugs 318 of the junction box 108. Thus, the extent to which the bracket 36B intrudes into the interior of the junction box 108 is minimized, and in particular, the thickness of the extension arm 120A is minimized.

[0094] In this embodiment, as shown, the base 324 and the extension arm 120A are formed from a single plate, which is stamped or cut to remove material to form the channel 328. At the distal end of the channel 328, a slit is formed, and the lug 124A is formed by simply bending the distal end of the extension arm 120B, as shown. Figure 19 As shown. An additional bend arranges the extension arm perpendicular to the base 324, forming a support lug 338. A lug hole 332 is formed through the support lug 338, allowing a mounting screw to pass through the lug hole 322 and into a box screw lug 318. The length of the extension arm 120A positions the base 324 on the bottom surface of the junction box 108, where maximum space is required. Alternatively, the length of the extension arm 120A can position the socket 20 at a predetermined distance from the opening of the junction box 108. As per the description of the extension arm 120 (… Figures 4-5 As described in the text, such as Figure 17 As shown, the extension arm 120A can be formed into two parts, which can be fastened together to form different lengths, so the extension arm 120A can be adjusted on site.

[0095] exist Figure 20 middle, Figure 19 The embodiment illustrates two-part extension arm 120A, wherein an extension arm extender 334 is attached to a shortened extension arm 120B. The extension arm 334 and the shortened extension arm 120B can be attached to each other by any known means, including threaded fasteners, clips, clamps, or other connections. One or both of the extender 334 or the arm 120B may include multiple openings for fasteners, thereby achieving multiple combined lengths, for example, corresponding to the commonly used junction box 108 size. Figure 21 It shows Figure 19Alternatively, embodiment 20 may be arranged within an extended ring-shaped electrical enclosure, which resembles a junction box with an open bottom. This provides additional space for wires and connectors, but the precise height of socket 20 is suitable for mounting devices including plug 30.

[0096] exist Figure 23 In this configuration, junction box 148 has a plurality of vertically aligned, threadable holes 336 located on opposite inner sides of junction box 108B. A bracket 36C and extension arm 120C form a gap through which a screw can pass and screw into a selected hole 148. This allows for precise vertical alignment of the socket 20. Since bracket 36C is secured via holes 336, lugs 338 may be omitted, as shown, or optional accessories may be provided for addition or replacement. Alternatively, extension arms 120 or 120A may provide one or more holes as an alternative to slotted extension arms 120C.

[0097] exist Figure 24 In this embodiment of the invention, the socket 20A is mechanically and electrically connected to the Edison-type base. The assembly device 22A can be screwed into a standard, unmodified recessed lighting device (not shown) to form a mechanical and electrical connection. The socket conductor 38 is electrically connected to the neutral and thermal contacts of the Edison-type connector. Otherwise, the socket 20A is... Figure 8 The receptacle 20 or other receptacles with release levers 148 / 148A described herein are identical, which facilitates the release of receptacle 20A when device 22A is embedded in a standard embedded device. The dimensions of neck 344 allow device 22A to achieve the desired overall height. Similarly, the height of lever extension 162 can be calibrated or adjustable, for example, by threading the distal end of the lever into a position that the user can push, depending on the needs of a particular application.
