Description

A panel transfer electrical box Technical Field

[0001] The present application relates to the technical field of Internet of Things intelligent switch panels, and in particular to a panel adapter electrical box. Background Art

[0002] With the development of the Internet and Internet of Things technology, smart furniture is becoming more and more popular and used, such as smart door locks, electric curtains, or smart home appliances.

[0003] In the prior art, in order to use smart furniture, it is necessary to set up a smart or scene switch converter. At the same time, in order to use smart terminals, such as mobile phones or tablets, different power supplies need to be provided, such as AC power output or USB DC voltage output.

[0004] Existing smart or scene switch converters are generally a wall-mounted adapter board that extends from a standard AC power socket on the wall to connect to multiple branch circuits. At the same time, the adapter board further extends to connect to smart switch panels and multi-port USB panels.

[0005] The standard dimensions of existing 86-type junction boxes are 86*86*32 mm. Conventional outlets installed using 86-type junction boxes typically have a five- or four-hole panel that is screwed into the concealed 86-type junction box. Due to its aesthetically pleasing concealed design, it has long been widely adopted as a standard building material. These conventional outlets, typically with five or four holes, provide power for various appliances in offices and daily life. In IoT, remote control, or multi-port DC output scenarios, plugging in conventional splitter adapters requires significant space within the standard wall junction box and requires the splitter adapters to protrude further from the wall to accommodate various smart panels. This conventional plug-in method for splitter adapters and various smart panels causes the overall smart conversion device to protrude significantly from the wall, impacting the aesthetics of interior decoration. Furthermore, with the multi-layered plug-in method, the panel pins require mechanical connections in addition to electrical connections. This can easily cause them to fall out if the connection is unstable or if they are accidentally bumped. This poor electrical connection stability for IoT-based smart furniture compromises the overall user experience. Summary of the Invention

[0006] Based on this, in order to solve the above-mentioned problems in traditional technology, the present application proposes a method of leaving sufficient winding space in the standard wall wiring base box. The remaining space is used to complete the plug-in electrical connection between the adapter module and the panel through spatial dislocation and modularization, and to fully accommodate the circuit on the back of the panel. The electrical box can be directly output to the outside of the electrical terminal, and can realize various intelligent application control and Internet of Things control panel adapter electrical boxes with the smallest volume.

[0013] In order to fix the panel, a first receiving groove is set on the second frame of the electrical box, and at least one first tenon is set on the wall surface of the first receiving groove of the second frame.

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] As shown in Figures 1, 2, and 3, the panel adapter box of this embodiment includes a box body 1 and an adapter module 2. The box body includes a bottom wall 11, four side walls 12-15, and a frame 16-19. The bottom and four side walls of the box body 1 are designed to accommodate an 86-type junction box or open box, with space for wiring at the bottom of the 86-type junction box reserved. The frame of the box body 1 is substantially flush with the top of the 86-type junction box. This allows the box body to be essentially flush with the wall after the panel is attached, just like a regular outlet. In this embodiment, to accommodate the 86-type closed box configuration of building wiring, the length D2 of the box body 1 is within 88 mm, the width D3 of the box body is within 88 mm, and the height of the box body accounts for the majority of the height of the 86-type open box or 86-type closed box. This ensures that the panel adapter, when attached to the panel, is essentially flush with the wall, just like a regular outlet, while also enabling various intelligent application control, Internet of Things control, and remote control.

[0037] As shown in FIG2 , the bottom wall 11 is provided with multiple modular areas within a transverse plane, i.e., within a plane defined by the X-axis and the Y-axis. In the embodiment shown in FIG2 , four modular areas A1-A4 are provided. It is understood that two, three, or five modular areas may also be provided. A single modular area does not exceed one-half of the bottom wall area.

[0038] The housing 1 forms a plurality of partitioned spaces C1-C4 along the longitudinal Z-axis from each module area. In the embodiment shown in FIG2 , the housing 1 extends from module area A1 along the Z-axis to form partitioned space C1. The adapter module 2 is mounted on the first module area A1 of the bottom wall 11 and is located within the partitioned space C1 corresponding to the first module area A1.

[0039] The adapter module 2 includes an input terminal and a panel plug-in terminal. The input terminal is arranged at the back of the first module area A1 of the bottom wall 11 and is connected to the mains power line through a plug-in interface. The panel plug-in terminal is arranged within the space range of the first partition space C1. The input terminal and the panel plug-in terminal are connected by a adapter circuit. In order to further optimize the space through spatial dislocation, the input terminal is fully or partially retracted into the partition space C1 corresponding to the first module area A1. For example, the partition space C1 of the box body 1 shown in Figure 2 is a columnar space with a height close to H starting from the first module area A1 of the bottom wall 11. The adapter module 2 is installed within the range of one of the partition spaces C1-C4. In this embodiment, the adapter module 2 is arranged in the first partition space C1, and can also be arranged in the second partition space C2 or the third partition space C3 or the fourth partition space C4. The structure of the adapter module 2 is retracted as much as possible in the first partition space to optimize space utilization.

[0040] The adapter module 2 includes an input terminal for connecting to the mains power line, which is located outside the box body 1, and a panel plug terminal, which is located in a corresponding partitioned space within the box body. The input terminal and the panel plug terminal are connected by an adapter circuit. The panel plug terminal has jacks arranged in a predetermined pattern, such as jacks 2136.

[0041] Please refer to Figures 11 and 12. In this embodiment, the panel 9 is a smart panel or a DC panel, such as a scene switch panel, a multi-port USB fast charging panel, a smart socket panel, or a smart switch panel. The panel includes a cover 90 and a rearward-protruding housing 92 for mounting circuit components. The pin module structure of the panel 9 matches the adapter module 2 in the first partition space C1, including a first step 93, a second step 94, and a third step 95. The first step is recessed near the cover 90 of the panel 9 and is provided with at least a neutral pin 912 and a live pin. When plugging in, the neutral, ground, and live pins of the panel, or in embodiments where no ground is provided, the neutral and live pins, need to be plugged into corresponding sockets in the electrical box. The panel plug-in end needs to be raised so that it is sufficiently close to the pins on the first step, which is the most recessed part of the panel 9, to establish an electrical connection. The pins of panel 9, such as pin 912, extend from the control circuit board in cover 90. This control circuit board is typically located at the front end of panel 9. To ensure a stable electrical connection, the panel plug-in terminal of the electrical box must be sufficiently close to the panel pins. This is reflected in the panel-to-electrical box structure, where the panel plug-in terminal is sufficiently close to the frame within the corresponding partition space.

[0042] Six plugs no more than three-quarters

[0043] In a specific implementation, the box body includes a first side wall 12, a second side wall 13, a third side wall 14, and a fourth side wall 15. The first side wall 12 and the third side wall 14 are provided with fixed steps connected to the 86-type junction box 100, and the second side wall 13 and the fourth side wall 15 are provided with a fixing structure for connecting to the panel. The frame includes a first frame 16 connected to the first side wall 12, a second frame 17 connected to the second side wall 13, a third frame 18 connected to the third side wall 14, and a fourth frame 19 connected to the fourth side wall 15.

[0044] As shown in Figures 1 and 2, a first fixing step extending to the first frame 16 is provided on the inner side of the first side wall 12, and a first countersunk hole 161 is opened on the first fixing step. A second fixing step extending to the third frame 18 is provided on the inner side of the third side wall 14, and a second countersunk hole 181 is opened on the second fixing step.

[0045] To connect the panel adapter box and the intelligent switch panel, as shown in Figure 2, a first receiving slot 171 is provided on the second frame 17 of the electrical box. At least one first latch 172 is provided on the wall of the first receiving slot 171, with two provided in this embodiment. A second receiving slot 191 and at least one second latch, corresponding to the first latch, are also provided on the fourth frame 19 of the electrical box. The electrical box and the panel can be detachably connected at two locations, one above and one below.

[0046] 5 and 13 , in the embodiment with a ground wire, the switching circuit includes a neutral switching circuit 46, a ground switching circuit 45, and a live switching circuit 47. In the embodiment without a ground wire, the switching circuit of the switching module 2 includes a neutral switching circuit 46 and a live switching circuit 47.

[0047] As shown in FIG13 , in an embodiment with a ground wire, the neutral wire switching circuit 46 includes a neutral wire interface 463 and a neutral wire contact spring 461 disposed on the back of the bottom wall 11. The neutral wire contact spring 461 is connected to the neutral wire interface 463 via a conductive sheet 462. The ground wire switching circuit 45 includes a ground wire interface 453 and a ground wire contact spring 451 disposed on the back of the bottom wall 11. The ground wire contact spring 451 is connected to the ground wire interface 453 via a conductive sheet 452. The live wire switching circuit includes a live wire interface 473 and a live wire contact spring 471 disposed on the back of the bottom wall 11. The live wire contact spring 471 is connected to the live wire interface 473 via a conductive sheet 472.

[0048] Referring to Figures 3 and 4 , the panel adapter box is equipped with a ground wire. The input terminal includes a neutral wire interface 110, a ground wire interface 111, and a live wire interface 112. The neutral wire interface 110 is adjustable by a neutral wire locking member 113 at a 90-degree angle or a tilt angle K; the ground wire interface 111 is adjustable by a ground wire locking member 114 at a 90-degree angle or a tilt angle K; and the live wire interface 112 is adjustable by a live wire locking member 115 at a 90-degree angle or a tilt angle K. The tilt angle K ranges from 0 to 90 degrees.

[0049] As shown in Figure 13, the AC power wire interface of the above input end is retracted as much as possible into the partition space corresponding to the same module area to maximize space utilization while ensuring safety regulations. In order to establish an electrical connection between the AC power wire and the switching circuit, each wire locking piece of the input end needs to be tilted 90 degrees or at an angle K, and a screw tightening operation slot is provided on the back of the first module area A1 of the box body 1, so that under the premise of the wire interface being retracted as much as possible, that is, under the premise that the input end is fully or partially retracted into the partition space corresponding to the same module area, wiring and disconnection can still be conveniently performed.

[0050] As shown in FIG4 , the input end is slightly protruding, occupying a smaller height H2 of the first partition space, which is added to the height H1 of the first partition space in the panel transfer box to form the height H of the box body 1 .

[0051] Please refer to Figure 5. In the design of the adapter module, the bottom wall 11 is provided with multiple partitions, such as partition 117, in the first partition space C1 where the adapter module 2 is located. In the embodiment of providing a ground wire as shown in Figure 5, multiple partitions separate the live wire (L) insulation chamber, the ground wire (E) insulation chamber, and the neutral wire (N) insulation chamber. The live wire insulation chamber is provided with a live wire contact spring 46, the ground wire insulation chamber is provided with a ground wire contact spring 45, and the neutral wire insulation chamber is provided with a neutral wire contact spring 47. The adapter module 2 is provided with two fixing buckles 1171 and 1172 on the left and right partitions at the outermost edges.

[0052] In the internal structure of the panel transfer box, the panel plug end includes an insulating plate 32 mounted on the partition and a plug cover 21. The insulating plate 32 has at least a neutral wire socket and a ground wire socket. In embodiments with a ground wire, the insulating plate 32 also has a ground wire socket 321.

[0053] Please also refer to Figure 10. The plug-in cover 21 has a three-step structure, including a bottom step 211, a middle step 212, and a top step 213. The bottom step 211 is provided with a first cover buckle 2115 for engaging with the bottom wall, and fixing slots 2121 and 2123 for engaging with the fixing buckles of the partition. The middle step 212 is provided with a screw lock hole 2122. The top step 2123 is provided with a second cover buckle 2131 and is provided with at least a neutral wire jack and a live wire jack. In the embodiment shown in Figure 5, the top step 212 is provided with a ground wire jack 2135, a neutral wire jack 2136, and a live wire jack 2137.

[0054] The plug cover 21 is provided with a spring positioning column 2134 below the bottom live wire socket 2134 .

[0055] To achieve modular installation of each partitioned space, a first connector 119 is provided at the center of the bottom wall 11. In this embodiment, this first connector 119 is a fixed block with a slot defined therein. A second connector is provided on one side of the plug-in cover 21 to mate with the first connector for secure connection. In this embodiment, this second connector is a first cover buckle 2115, which snaps into the slot on the fixed block to secure the plug-in cover.

[0056] A safety door mechanism is provided between the insulating plate 32 and the plug cover 21. This safety door mechanism includes a safety door plate 31 slidably mounted on the insulating plate 32. The safety door plate 31 includes a tilted push door 311, which is aligned with the live wire socket 2137. The safety door plate 31 also includes a spring positioning block 312, on which a spring 35 is mounted. The other end of the spring 35 is sleeved onto a spring positioning post 2134 below the plug cover 21. The safety door plate 31 is in sliding contact with the plug cover 21 via the spring 35. When the panel pins are plugged into the adapter module 2, the tilted push door 311, pushed by the pins, causes the safety door plate to slide to the side, exposing the live wire contact, thus preventing accidental electric shock.

[0057] As shown in Figures 8 and 9, the arrangement of the neutral wire jack and the live wire jack, or the neutral wire jack, the ground wire jack, and the live wire jack, provided on the plug cover 21 can be changed based on the internal circuit design of the switch panel and the available space of the corresponding panel plug-in portion, with the purpose of optimizing the use of space. Referring to Figure 8, in the embodiment of the middle frame without a ground wire, the arrangement of the jacks on the panel plug-in end of the panel adapter box includes a horizontal arrangement 51, a vertical arrangement 53, and a diagonal arrangement 52. Referring to Figure 9, in the embodiment of the middle frame with a ground wire, the arrangement of the jacks on the panel plug-in end of the panel adapter box includes a horizontal arrangement 54, a vertical arrangement 56, a diagonal arrangement 55, or a staggered arrangement.

[0058] In order to adapt to the standard wall junction boxes of various countries, the first countersunk hole 161 and the second countersunk hole 182 are runway-shaped countersunk holes that provide locking redundancy. The center axis hole distance between the first countersunk hole 161 and the second countersunk hole 182 ranges from 57 to 63 mm, so that when multiple 86-type junction boxes 100 are installed side by side in the living room, different panels can still be easily plugged in and installed without interfering with or squeezing each other.

[0059] Referring to Figures 6 and 7 , in the separate grounding embodiment, the input terminal has a separate grounding interface located behind the first module area A1 on the bottom wall 11. This interface is controlled by a grounding locking member at the back of the housing 1', tilted 90 degrees or at an angle K. In this embodiment, the plug-in cover 21 only accommodates the neutral and live wire sockets, thus narrowing the width to create space within the first compartment C1 for the grounding contact spring.

[0060] In addition to being the ground contact spring 471 shown in FIG5 , the ground contact spring can also be the protruding grounding piece 2135' shown in FIG6 , in which case the adapter module has a live wire socket 2136' and a neutral wire socket 2137'. The ground contact spring can also be the spring-type spring 2135" shown in FIG7 , in which case the adapter module has a live wire socket 2136" and a neutral wire socket 2137". The ground contact spring can also be a recessed grounding piece.

[0061] The above disclosure is only a preferred embodiment of the present application, and certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
