Description

Technical Field

[0001] This invention relates to the field of electrical installation technology, specifically to an embedded flush modular electrical panel system, and more particularly to an improved system that adds contact-type automatic electrical connection function while retaining the original mechanical quick-release structure. It is suitable for switches, sockets and other electrical accessories, and can be installed on various mounting surfaces such as walls, wood panels, and gypsum boards. Background Technology

[0002] The applicant previously filed a patent application (application number 2025119070038) entitled "Embedded Flush Modular Socket System" (hereinafter referred to as the basic patent) on December 17, 2025. Its core technologies include: the base box and socket module are positioned in the X and Y directions through a guide structure, and locked in the Z direction through a locking structure; the panel is installed flush with the mounting base, with no unlocking structure on the outside; the inherent socket holes (such as grounding holes) of the socket module extend to the locking structure to form an unlocking channel, which is unlocked by inserting a special tool through the socket hole. This solution enables quick mechanical disassembly of the module, solving the problems of traditional socket panels protruding from the mounting base and difficulty in maintenance under flush installation conditions.

[0003] However, the aforementioned patents have the following shortcomings: First, the connection between the electrical module and the mains power line still uses the traditional method—the wires are fixed to the back of the inspection panel via terminals or soldering. This means that even if the mechanical structure allows for quick disconnection, the electrical connection still relies on manual wiring and disconnection. For scenarios requiring frequent module replacement (such as damaged switch buttons, malfunctioning springs, or smart panel upgrades), users still need to hire an electrician, significantly reducing convenience.

[0004] Secondly, the basic patent only addresses the design of socket modules, lacking a unified quick-release solution for other electrical modules such as switches. Switch modules are the most frequently used components in electrical systems, and button detachment and loss of elasticity are common malfunctions. Once a traditional switch is damaged, it can only be replaced as a whole, requiring power disconnection, wire disconnection, and rewiring, which ordinary users cannot do themselves.

[0005] Third, traditional wire connection methods have potential risks such as wire fatigue fracture and screw loosening after repeated disassembly and assembly, which are detrimental to the long-term reliability of modular systems.

[0006] Fourth, the mounting flange of the bottom box is too small, resulting in insufficient reliability in fixing it to the edge of the opening in porous substrates such as aerated concrete blocks and hollow bricks. Summary of the Invention

[0007] Technical problems to be solved: Based on the mechanical quick-release structure of the basic patent, this invention further solves the following technical problems: It enables automatic electrical connection when electrical modules are inserted and automatic disconnection when they are removed, eliminating the need for manual wiring or disconnection.

[0008] Improved maintenance convenience, enabling users to replace electrical modules themselves.

[0009] It maintains full compatibility with the core features of the basic patent, such as mechanical structure, unlocking method, and flush panel installation.

[0010] Improve the installation reliability of the base box on loose substrate and the ease of operation of the unlocking tool.

[0011] Technical solution

[0012] Based on the basic patented embedded flush detachable system, this invention adds the following core technical features: Key Feature 1: Contact-type Automatic Electrical Connection The inspection plate (8) is equipped with a conductive contact female base (82), which is an elastic clamping structure; the electrical module (4) is equipped with a corresponding conductive contact (42), which is a conductive insert or a conductive pad. When the module is pushed into the bottom box (5) along the guide structure, the conductive contact automatically fits with the female base to complete the electrical connection; the connection is automatically disconnected when the module is pulled out. The mains power wiring is only operated once when the bottom box is installed, and no wiring is required for subsequent module replacements.

[0013] The conductive contact can be a conductive insert with an elastic clamping structure, or a conductive pad with an elastic pin.

[0014] Key Feature 2: Unlocking channels and contact points are spatially staggered. The electrical module (4) is provided with at least one socket or tool through hole extending to the locking structure (43) to form an unlocking channel (41). The unlocking channel is spatially staggered from the conductive contact (42) and the female socket (82) to prevent the unlocking tool (1) from accidentally touching the live parts when it is inserted.

[0015] Core Feature 3: Switch Module Unlock Channel Based on the extension of the socket hole to the unlocking channel in the socket module, the switch module adds at least one tool through hole extending to the locking structure position to form an unlocking channel, thereby achieving a tool unlocking method that is consistent with the socket module.

[0016] Core Feature 4: Large Flange Structure Design The mounting flange (51) of the base box (5) has an outward expansion dimension of not less than 25mm, covering the entire substrate area at the edge of the opening. This design increases the contact area between the base box and the mounting base surface (7), enabling reliable construction using various fixing methods such as mortar, tile adhesive, pneumatic nail gun, and expansion screws. It is especially suitable for scenarios where the fixing reliability of the opening edge of loose substrates such as aerated concrete blocks and hollow bricks is insufficient.

[0017] Core Feature 5: Wedge-shaped component flatness compensation A triangular wedge (6) with selectable thickness is provided between the base box (5) and the mounting base (7), which is inserted into the gap between the flange and the mounting base to compensate for the flatness deviation during construction and reduce the dependence on the accuracy of the workers' construction.

[0018] Core Feature 6: Anti-slip unlocking tool The end of the pull structure (11) of the special unlocking tool (1) is provided with anti-slip texture or serration (13) to improve the operating friction and facilitate one-handed operation to pull out the module.

[0019] Beneficial effects

[0020] Truly quick-release: Users can replace modules by hand without tools or touching wires. Pushing in connects and pulling out disconnects. Module replacement requires no tools or wiring, greatly improving maintenance efficiency. Suitable for batch maintenance scenarios such as homes, hotels, and property management companies.

[0021] Expanded coverage: A unified quick-release solution for sockets and switches forms a complete electrical panel system.

[0022] Enhanced safety: The unlocking channel and contact space are staggered to avoid accidental contact with live parts; the contact structure is enclosed on the back of the module, with no exposed live parts.

[0023] Improved construction reliability: The large flange structure design solves the installation problem of loose substrates; wedge compensation reduces the construction accuracy requirements.

[0024] Improved ease of use: The anti-slip design at the end of the unlocking tool enhances the one-handed operation experience.

[0025] Fully compatible with basic patents: core features such as guide structure, locking structure, and flush panel installation are all retained, and the original base box and panel can continue to be used.

[0026] Home emergency interoperability: When a module in a critical location is damaged, users can temporarily call up the same functional module from a non-critical location, and the empty space is filled with a model; once a new module is purchased, the non-critical location can be filled directly without rewiring, thus improving the self-healing ability of home electricity.

[0027] Expanding the smart home ecosystem: Users can unplug the ordinary module from any socket and replace it with a smart switch module to control preset smart lights or connect to a whole-house smart system. No rewiring is required, truly achieving a plug-and-play experience of "sockets becoming switches," significantly reducing the deployment threshold and renovation costs of smart homes.

[0028] Platform-based whole-house electrical equipment: By pre-installing universal junction boxes in locations such as ceilings and doorways, and utilizing existing L, N, L1, and L2 female connectors, it is compatible with traditional mechanical switches (using L, L1, and L2) and also supports various smart devices (using only L, N, and wireless communication). Users can freely interchange various functional modules such as ceiling lights, cameras, wireless APs, video doorbells, switches, and sockets without rewiring, achieving "one box for multiple uses" and fully modularizing wall and ceiling electrical equipment.

Detailed Implementation

[0033] The number and location of the wiring terminals in the external terminal compartment (83) of the inspection board (8) of this invention are completely consistent with those of traditional switches / sockets with corresponding functions. Taking a single-pole single-control switch as an example, the external terminal compartment has only two wiring terminals (live wire in, control wire out), and electricians can wire according to traditional habits without additional learning. A single-pole double-control switch has three wiring terminals (L, L1, L2), which are exactly the same as traditional double-pole switches. The wiring terminals of other functional modules (sockets, smart switches, etc.) also correspond one-to-one with traditional products. This design ensures zero learning cost for electricians during installation and completely avoids wiring errors caused by the new structure. For the specific structure of its internal wiring terminals, please refer to the basic patent (application number: 2025119070038). Figure 5 And corresponding explanations.

[0034] It should be noted that the socket module panel in the basic patent has socket holes (see basic patent). Figure 2 The unlocking tool can directly operate the locking structure through the socket, so there is no need to remove the panel when replacing the socket module. However, the switch module of this invention has no socket on the front (see Embodiment 1), and the panel (2) must be removed first to expose the unlocking channel (41) when replacing the switch module. The structural differences between the two modules have been fully disclosed in the basic patent and the embodiments of this specification. Appendix Figure 1 The diagram only shows a single female connector (82). Those skilled in the art should understand that in actual applications, the inspection board is equipped with multiple female connectors (such as the four female connectors L, L1, L2, and N described in Example 1). The specific number and arrangement are based on the example. The attached diagram is only a schematic diagram of the structural principle.

[0035] Example 1 (Switch Module) This embodiment takes a single-control dual-control switch module as an example and uses a wall as the installation base, but it is also applicable to other bases such as wood panels and gypsum boards, illustrating the preferred embodiment of the present invention.

[0036] Back box and access panel: The bottom box (5) has an internal dimension of 75mm×75mm×50mm and is equipped with a guide structure (52) (guide rail) around its perimeter. The inspection plate (8) is detachably installed at the bottom of the bottom box.

[0037] Four conductive contact females (82) are fixed on the side of the inspection plate facing the electrical module. The females are X-shaped elastic clamping structures with the openings facing the module insertion direction. Their corresponding relationships are as follows: Female connector L: Connects to the live wire (L) Female connector L1: Connects to the first control line (to the light fixture, load line). Female connector L2: Connects to the second control line (unused in single-control scenarios, connects to another control line in dual-control scenarios) Female connector N: Connect the neutral wire (N, optional, reserved for smart switches) The inspection board has an external terminal compartment (83) on the reverse side. When installing, the electrician first removes the inspection board (8) from the bottom box (5) and flips it over to the back. Use a screwdriver to open the cover of the external terminal compartment (83) to expose the internal wiring terminals. The electrician follows the traditional wiring habits to insert the live wire into the L terminal, the control wire (to the light fixture) into the L1 terminal, the other control wire into the L2 terminal in the case of dual control, and the neutral wire (if laid) into the N terminal. Tighten the screws or press the quick-connect terminals to complete the fixation. After the wiring is completed, close the terminal compartment cover and put the inspection board (8) back into the bottom of the bottom box (5).

[0038] Switch module: The electrical module (4) is a single-position switch module (compatible with single-control, double-control, or intelligent switches), and is equipped with a guide structure (44) (guide groove) around its perimeter, which slides in conjunction with the guide rail (52) of the base box. The back of the module has four conductive contacts (42), which are conductive inserts, and their positions correspond one-to-one with the four female connectors (82) on the inspection plate. When the module is pushed in, the X-shaped elastic clamping structure of the female connector automatically opens and clamps the conductive inserts, completing the electrical connection.

[0039] Depending on the switch type, the internal circuit connection of the module is as follows: Single-control: Only the L and L1 contacts are connected to the internal switching circuit, while the L2 and N contacts are left unconnected within the module.

[0040] One-way dual control: Connect the three contacts L, L1, and L2 to the internal dual control circuit, and leave the N contact floating.

[0041] Zero-live smart switch: Connect the three contacts L, L1, and N to the smart control circuit (L1 controls the lamp), and leave L2 floating.

[0042] Dual-control smart switch: All four contacts are connected to the circuit (L, L1, L2, N).

[0043] The locking structure (43) is a double elastic latch located at the bottom of the module. Since there is no socket on the front of the switch module, a special tool through hole is provided on the front of its housing as an unlocking channel (41). The unlocking channel extends to the position of the locking structure and is spatially offset from the conductive contact (42) (the unlocking channel is located on one side of the module and the conductive contact is located on the other side) to avoid accidental contact with live parts when the unlocking tool is inserted.

[0044] In this embodiment, the conductive contacts are arranged in the corresponding positions described above, and are directly extended from the internal conductive structure of the module, eliminating the need for additional wires and keeping mass production costs under control. In another variant, the contacts can also be guided to one side of the module and arranged in a row to accommodate different socket layout requirements.

[0045] Installation and replacement procedures: During installation, the user simply pushes the electrical module (4) of the pre-attached panel assembly (3) directly into the bottom box (5) along the guide structure (52). When pushed to the bottom, the locking structure (43) automatically engages with the locking part (81) of the inspection plate, and the conductive contact (42) automatically completes the electrical connection with the female connector (82). The panel assembly (3) is flush with the mounting base (7). The entire process requires no tools; simply push it in.

[0046] When the switch button is damaged or the module needs to be replaced, the user should first disconnect the main power supply of the room or the power supply of the corresponding circuit, then remove the panel (2), insert the pin (12) of the unlocking tool (1) into the unlocking channel (41), push the locking structure (43) to disengage it from the locking part (81) of the inspection plate, and pull out the module by holding the pull structure (11). During the pulling process, the conductive contact (42) and the female socket (82) will automatically disconnect. After the new module is pushed in, the panel can be snapped back on without rewiring or adjustment.

[0047] The entire process requires only one unlocking tool, no screwdriver or wires are needed, and can be completed by ordinary users.

[0048] Panel assembly: Panel (2) is embedded in panel assembly (3). Users can remove panel (2) separately and install it flush with the mounting base (7). The material can be ceramic tile, paint panel or plastic panel.

[0049] The number of contacts, number of female connectors, and connection methods of multi-position switch modules (two-position, three-position, etc.) are similar, and the principle is the same, so they will not be repeated here.

[0050] Unlocking tools: The unlocking tool (1) includes a pin (12) positioned corresponding to the unlocking channel (41) on the front of the switch module, and a pull mechanism (11) located at the rear. The end of the pull mechanism (11) is provided with anti-slip texture or serrations (13) for easy gripping and applying force. The pin (12) is long enough to extend to the locking structure (43).

[0051] Instructions for use: Insert the pin (12) into the unlocking channel (41), push the locking structure (43) to disengage it from the locking part (81), and at the same time hold the pull structure (11) and pull the module outward.

[0052] Example 2 (Upgraded version of basic five-hole socket) This embodiment is an improvement upon Embodiment 1 of the basic patent. The difference from Embodiment 1 is that the electrical module is a five-hole socket module. Three conductive contacts (42) are provided on the back of the module, which are conductive inserts corresponding to the live wire, neutral wire, and ground wire, respectively. The corresponding female connector (82) on the inspection plate has an elastic clamping structure (same as Embodiment 1). The ground wire socket extends to the locking structure position to form an unlocking channel (41), which is staggered from the conductive contacts. The unlocking tool uses three pins, with the ground pin being long enough to reach the latch. The remaining structure is the same as Embodiment 1. The unlocking principle of the socket module can be found in [reference needed]. Figure 3 The difference lies in using the grounding socket (instead of the special tool through hole) as the unlocking channel.

[0053] Example 3 (Elastic Ejector Pin Solution) The difference from Embodiments 1 or 2 is that the female connector (82) is a pogo pin, and the conductive contact (42) is a circular copper pad. The pogo pin has a built-in spring to provide stable contact pressure. An annular guide groove is provided on the back of the module to ensure that the pogo pin falls precisely in the center of the pad. This solution is suitable for low-voltage DC luminaires that require higher insertion / removal life or low contact resistance.

[0054] Example 4 (Compensation for flatness of mounting base) For situations involving renovation of old buildings or uneven installation surfaces, triangular wedges (6) of selectable thickness (0.5mm, 1mm, 2mm) are installed between the mounting flange (51) and the installation surface (7). The wedges are triangular plastic pieces that are inserted from the edge of the flange into the gap between the base box and the installation surface. By selecting wedges of different thicknesses or numbers, unevenness deviations of the installation surface can be locally compensated, ensuring that the panel is flush with the installation surface and the gap is uniform.

[0055] Example 5 (Cross-functional interchange: Socket becomes smart switch) This embodiment uses a five-hole socket box as an example to illustrate the extended application of the present invention in smart home scenarios.

[0056] A user's home currently has a standard five-hole socket module (as described in Example 2) installed at a certain socket location for daily power supply. When the user needs to add a smart switch function to this location (e.g., to control a smart light in the living room), there is no need to rewire; simply follow these steps: (1) Use the unlocking tool (1) to directly pull the original five-hole socket module out of the bottom box (5) (the panel structure of the socket module and the basic patent) Figure 2 Similarly, the panel has a socket, allowing the unlocking tool to operate the locking mechanism directly through the socket without removing the panel separately. (2) Take a smart switch module (4), which has a conductive contact (42) (conductive insert) on its back, which corresponds one-to-one with the conductive contact female (82) on the inspection board (8) in the bottom box; (3) Push the smart switch module directly into the bottom box along the guide structure (52). When it is pushed to the bottom, the locking structure (43) automatically engages, and the conductive contact and the socket automatically complete the electrical connection (powered by live and neutral wires). (4) After the smart switch module is powered on, it automatically starts the pairing mode and establishes a connection with the preset smart light through wireless communication protocols (such as Bluetooth Mesh, Zigbee or Wi-Fi); (5) Users can control the smart light's on / off state, brightness adjustment, and other operations via the buttons on the smart switch module or a mobile app (the smart switch module's panel is integrated with its main body; after being pushed in, it automatically aligns with the mounting base, eliminating the need for additional panel clipping). The entire conversion process requires only one unlocking tool. Before operation, the power supply to the corresponding circuit should be disconnected. No rewiring is required, and ordinary users can complete the functional conversion from "ordinary socket" to "smart switch" within minutes. This smart switch module can work independently without relying on a gateway, and can also be connected to a home smart home system to achieve scene linkage.

[0057] Specifically, the smart switch module integrates a wireless communication module (such as Bluetooth Mesh or Zigbee) and a control chip. Upon initial power-up, the module automatically enters pairing mode, allowing users to bind the smart switch to the target smart light via a mobile app. Once bound, each press of the switch button sends a switching command to the bound smart light via the wireless communication module. The smart switch module's live and neutral power is supplied by the maintenance board socket, eliminating the need for an additional battery or neutral wire, ensuring long-term stable operation.

[0058] Example 6 (Module Interchange - Emergency Use with Same Function) For example, if the switch button in the bedroom is damaged, the user can unplug the same model switch module from the balcony and push it into the bedroom's junction box; the balcony junction box should be temporarily sealed with an empty module model. After purchasing a new switch module the next day, simply push the new module into the balcony junction box. At this point, both the bedroom and balcony will resume normal use without any additional operation.

[0059] Example 7 (Empty Module Model - For Construction Aid) This embodiment provides an empty module model. The empty module model has the same external dimensions, guide structure (52), and locking structure (43) as the electrical module (4), but does not have conductive contacts or circuits inside. The empty module model can be injection molded from low-cost plastic and can be reused. During the installation base construction stage, after fixing the bottom box (5), the empty module model is first pushed into the bottom box so that its outer surface is flush with the expected installation base. The mason or electrician uses the outer surface of the empty module model as a reference to perform plastering, tiling, and other operations to ensure that the final installation base is flush with the surface of the empty module model. After the installation base is completed, the empty module model is removed, and then the actual electrical module (4) and panel assembly are pushed in to achieve perfect flushness between the panel and the installation base.

[0060] Example 8 (Empty Module Model - Pre-embedded for later use) During the renovation phase, users can pre-install multiple base boxes (5) in locations such as cabinets, desks, and entryways according to future electricity needs, and insert empty module models into the base boxes that are not currently in use. The external dimensions and guide structure (52) of the empty module models are exactly the same as those of the electrical modules (4), but they do not have conductive contacts or circuits inside, and are only used to seal the openings of the base boxes and keep the mounting surface flat. When users need to add sockets, switches, or other functional modules in the reserved locations later, they only need to remove the empty module models and directly push in the corresponding electrical modules (4), without having to re-groove and rewire or damage the wall. The empty module models can be made of low-cost plastic injection molding and can be reused.

[0061] Example 9 (Multi-purpose back box at the doorway – switch, socket, and video doorbell can be interchanged) This embodiment uses a pre-embedded base box at the entrance hall of a residence as an example to illustrate the application of the present invention in a multi-functional doorway scenario.

[0062] During the renovation phase, the electrician connects the live wire to L and the neutral wire to N, and connects the control wire to L1 as needed (e.g., to control the entryway light). L2 can be left unconnected. All wiring is located in the external terminal compartment (83) of the inspection board (8).

[0063] After check-in, users can select different functional modules according to their needs. All modules are compatible with the guide structure (52) and locking structure (43) of the base box and can be used immediately after being pushed in. Mechanical switch module: Only L and L1 are connected on the back of the module. The control signal output from L1 controls the entryway light. The module does not require N and does not use wireless communication.

[0064] Socket module: The back of the module is connected to L and N (as well as the ground wire defined by L1 or L2) to provide a 220V power supply interface.

[0065] Video doorbell module: The back of the module connects to L and N, and internally integrates a step-down circuit (220V→5V / 12V) and a wireless communication module (such as Wi-Fi or Bluetooth). It automatically powers on after being pushed in and communicates wirelessly with the indoor unit or mobile app. The front of the module features a camera, doorbell button, and microphone, flush with the mounting surface. When the user needs to replace it with a switch or socket, simply unplug this module and push in the desired module; no rewiring is required.

[0066] The entire process requires no disassembly of the base box or contact with the wires. Users can replace the module at any time according to changes in their life needs, truly realizing "one base box, infinite possibilities".

[0067] Example 10 (Ceiling pre-embedded box – ceiling light, camera, and wireless AP can be interchanged) This embodiment uses a base box pre-embedded in the living room ceiling as an example to illustrate the application of the present invention in ceiling-mounted device scenarios.

[0068] During the renovation phase, the electrician will connect the live wire to L and the neutral wire to N. L1 and L2 can be left unconnected or used for other controls.

[0069] After moving in, users can select and replace the ceiling module as needed: Ceiling-mounted smart light module: The back of the module connects to L and N ports, and internally integrates an LED driver and wireless communication module (such as Bluetooth Mesh or Zigbee). It automatically powers on after being pushed in, and users can control the light's on / off state, color temperature, and brightness via a mobile app or smart speaker. The front of the module is flush with the ceiling, with no exposed screws.

[0070] Ceiling-mounted camera module: The back of the module connects to L and N, and internally integrates a step-down circuit, Wi-Fi module, and camera. It automatically powers on and connects to the home network after being pushed in, allowing users to view the monitoring footage in real-time via a mobile app. The module is discreet and requires no external power or network cable.

[0071] Wireless AP Module: The back of the module connects to ports L and N, and integrates a Wi-Fi routing chip and antenna. It automatically powers on after being pushed in and connects to the main router via a wireless mesh network, eliminating the need for pre-installed Ethernet cables. The front of the module is flush with the ceiling, with only indicator lights visible.

[0072] All modules use a uniform guide structure (52) and locking structure (43), which users can plug in and replace at any time. For example, when the children's room needs temporary monitoring, the camera module in the living room can be unplugged and pushed into the ceiling box in the children's room without rewiring.

[0073] Industrial applicability

[0074] This invention can be widely applied to electrical installations in residential, office, and commercial spaces, and is particularly suitable for prefabricated decoration, smart homes, and modular wall systems. Because it is fully compatible with the base box and panel of the basic patent, users can upgrade traditional wire-connected modules to quick-release contact modules without replacing the base box. Especially for high-frequency, easily damaged components such as switches, the "plug-and-play" capability of this invention will significantly reduce maintenance costs for properties, hotels, and homes, making it highly valuable for widespread adoption.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
