A first connector is provided in the inner frame and a second connector is provided in the inner box. Through the electrical connection of the first connector and the second connector, bare wire connection is no longer required when disassembling and repairing the inner box, thereby reducing the difficulty of repair and improving the safety of repair operations.

[0006] Another objective of this application is to provide a junction box having the aforementioned panel and bottom box, which eliminates the need to reconnect exposed wires during maintenance, thus simplifying maintenance operations and enhancing operational safety.

[0007] This application provides a panel bottom box, the panel bottom box comprising:

[0008] An inner frame, on which a first connector for electrical connection with a wire network is provided;

[0009] The inner box is provided with a second connector for electrical connection with the panel. The inner box is detachably and fixedly installed on the inner frame. After the inner box is installed on the inner frame, the second connector is electrically connected to the first connector.

[0010] As an optional implementation, the inner frame is provided with a first mounting part for fixing the inner frame.

[0011] As an optional implementation, a second mounting portion is provided on the inner frame, the second mounting portion being located near the inner bottom surface of the inner frame, and the first connector is mounted on the second mounting portion.

[0012] As an optional implementation, the inner frame is provided with a first limiting part for fixing the inner box to the inner frame. After the inner box is installed in the inner frame, the first limiting part restricts the inner box from coming out of the inner frame.

[0013] As an optional implementation, the inner box is provided with a fastener for fixing the inner box to the inner frame;

[0014] After the inner box is fixed to the inner frame, the first limiting part restricts the inner box from coming out of the inner frame by limiting the fixing member;

[0015] When the inner box is removed from the inner frame, the fastener is released from the fixation of the first limiting part, and the fastener remains intact on the inner box.

[0045] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0046] Referring to Figure 1, the technical solution of this application is a panel bottom box 10, which includes an inner frame 20 and an inner box 30.

[0047] The inner frame 20 is provided with a first connector 25 for electrical connection with the wire network, and the inner box 30 is provided with a second connector 35 for electrical connection with the panel 40. The inner box 30 is detachably and fixedly installed in the inner frame 20. After the inner box 30 is fixedly installed in the inner frame 20, the second connector 35 is electrically connected to the first connector 25. After the inner box 30 is removed from the inner frame 20, the second connector 35 separates from the first connector 25, and the second connector 35 remains intact in the inner box 30.

[0048] The first connector 25 in the inner frame 20 enables the panel back box 10 to be connected to power or a network. The network includes, but is not limited to, electrical power and signal networks.

[0049] The second connector 35 in the inner box 30 is electrically connected not only to the first connector 25, but also to the panel 40, so that the wire network of the panel 40 can be connected to the first connector 25.

[0050] In some embodiments, the panel back box 10 in this application can be a separate component. In some embodiments, the panel back box 10 can also be combined with the panel 40 to form an integral unit.

[0051] After the inner box 30 is fixedly installed in the inner frame 20, the second connector 35 in the inner box 30 is electrically connected to the first connector 25 in the inner frame 20, enabling the second connector 35 to access the network. After the inner box 30 is removed from the inner frame 20, the second connector 35 separates from the first connector 25, and the second connector 35 remains inside the inner box 30. After the inner box 30 is removed from the inner frame 20, the second connector 35 remains intact inside the inner box 30, and when the inner box 30 is fixedly installed back into the inner frame 20, the second connector 35 is electrically connected to the first connector 25 again. The second connector 35 and the first connector 25 in the inner box 30 are electrically connected and can be repeatedly disassembled and reassembled. This ensures that when disassembling or repairing the inner box 30, it is no longer necessary to disconnect and rewire bare wires, reducing the difficulty of repair and improving the safety of repair work. In the panel bottom box 10 of this application, when only the inner box 30 is replaced, no professional personnel are required to operate it. Home or office personnel can operate it themselves, which is simple, safe and quick.

[0052] In some embodiments, the inner frame 20 is further provided with a fourth connector 26 for an external wiring network. The fourth connector 26 is electrically connected to the first connector 25, and the first connector 25 is electrically connected to the external wiring network through the fourth connector 26.

[0053] By providing the fourth connector 26, the connectors in the inner frame 20 that are electrically connected to the external wiring network and the inner box 30 are distinguished, thus preventing mistaken wiring and ensuring safe and reliable operation. By providing the fourth connector 26 and connecting it to the first connector 25, the external wiring network can be reliably integrated into the inner frame 20.

[0054] In some embodiments, the first connector 25 is a male connector, and the second connector 35 is a female connector. After the inner box 30 is fixedly installed in the inner frame 20, the female connector mates with the male connector and is electrically connected. The fact that the second connector 35 is a female connector ensures that the second connector 35 retained in the inner box 30 will not be damaged when the inner box 30 is removed from the inner frame 20. In some operations requiring live operation, the female connector 35 also ensures that there will be no safety issues such as electric shock.

[0055] The first connector 25 and the second connector 35 are electrically connected, typically through a plug-in connection or a contact connection. When the first connector 25 is a male connector and the second connector 35 is a female connector, after the inner box 30 is placed inside the inner frame 20, the male connector is inserted into the female connector, achieving electrical connection between the second connector 35 and the first connector 25. The first connector 25 is inserted into the second connector 35 to achieve electrical connection, eliminating the need for bare wire connector connections, making the process simple and convenient.

[0056] In some embodiments, the first connector 25 is a circuit connector, and the second connector 35 is a circuit connector. The panel bottom box 10 is a power junction box.

[0057] In some embodiments, the first connector 25 is a signal connector, and the second connector 35 is a signal connector. The panel back box 10 is a signal junction box.

[0058] In some embodiments, the first connector 25 includes circuit terminals and signal terminals, and the second connector 35 also includes circuit terminals and signal terminals. The panel back box 10 enables electrical and signal connections.

[0059] In some embodiments, the inner frame 20 is provided with a first mounting part 21 for fixing the inner frame 20. The first mounting part 21 fixes the inner frame 20 itself in the mounting position, and then fixes the inner box 30 in the inner frame 20, thus realizing the fixed installation of the panel bottom box 10 in the mounting position.

[0060] For the installation of the inner frame 20, in some embodiments, a junction box or wiring trough is provided at the installation location. The wire network is connected to the junction box or wiring trough, and then the wire network cable in the junction box or wiring trough is electrically connected to the fourth connector 26 on the inner frame 20. Finally, the inner frame 20 is fixedly installed in the junction box or wiring trough. In some embodiments, the junction box is such as an 86 junction box, and the wiring trough is such as a mounting groove provided on the wall.

[0061] Referring to Figure 5, in some embodiments, the first mounting part 21 includes an inner frame mounting hole 212 or an inner frame mounting elongated hole 211 disposed on the inner frame 20. During installation of the inner frame 20, connectors such as screws or bolts are used to pass through the inner frame mounting elongated hole 211 or the inner frame mounting hole 212 to fix the inner frame 20. If the first mounting part 21 uses the inner frame mounting elongated hole 211, installation is flexible, avoiding installation difficulties or inability to install due to installation errors.

[0062] In some embodiments, the inner frame mounting hole 212 or the inner frame mounting elongated hole 211 is simultaneously provided on the inner frame 20, and the first mounting part 21 of the inner frame 20 has multiple mounting positions and mounting structures, which can be selected as needed.

[0063] In some embodiments, a second mounting portion 23 is provided on the inner frame 20, the second mounting portion 23 is disposed near the inner bottom surface of the inner frame 20, and the first connector 25 is mounted on the second mounting portion 23.

[0064] The second mounting part 23 provides a mounting position for the first connector 25, ensuring the fixation and stability of the first connector 25, ensuring the service life of the first connector 25, and ensuring the stable electrical connection between the first connector 25 and the wire network.

[0065] The second mounting part 23 is located near the inner bottom surface of the inner frame 20, so that the first connector 25 is located near the inner bottom surface of the inner frame 20. After the inner frame 20 is fixedly installed, the first connector 25 is placed on the inner bottom surface of the inner frame 20, providing sufficient space for the second connector 35 in the inner frame 20, which facilitates the connection between the second connector 35 and the first connector 25.

[0066] Referring to Figures 4 and 5, in some embodiments, the second mounting portion 23 may be two extension pieces 231 disposed on the inner frame 20, extending towards the inner bottom surface of the inner frame 20, and then the first connector 25 is fixed between the two extension pieces 231. The first connector 25 is detachably and fixedly connected to the second mounting portion 23. Of course, in other embodiments, the second mounting portion 23 may also be a connecting plate fixedly connected to the upper surface of the inner frame 20, and the first connector 25 is fixedly connected to the inner frame 20 through the connecting plate. In other embodiments, the second mounting portion 23 may also be a connecting frame, fixedly connected to the upper surface of the inner frame 20, and the first connector 25 is fixedly connected to the inner frame 20 through the connecting frame.

[0067] In some embodiments, the inner frame 20 is provided with a first limiting part 22 for fixing the inner box 30 in the inner frame 20. After the inner box 30 is installed in the inner frame 20, the first limiting part 22 restricts the inner box 30 from coming out of the inner frame 20.

[0068] The first limiting part 22 enables the inner box 30 to be installed in the inner frame 20, and at the same time, after the inner box 30 is installed in the inner frame 20, it restricts the inner box 30 from coming out of the inner frame 20, ensuring that the inner box 30 is installed in the inner frame 20.

[0069] Referring to Figures 3 and 4, in some embodiments, to facilitate the manufacturing of the inner frame 20, the inner frame 20 is set to a regular shape, such as a circle, ellipse, square, triangle, etc. The inner frame 20 is generally made of metal or high-strength plastic. The inner frame 20 is generally formed by casting, stamping, injection molding, blow molding, thermoforming, compression molding, etc. In some embodiments, the first limiting part 22 is generally the upper frame 221 of the inner frame 20, as shown in Figure 3, which has a simple structure and good limiting effect. If the first limiting part 22 is the upper frame 221 of the inner frame 20, when the inner box 30 is installed, after the inner box 30 is pressed into the inner frame 20, the upper frame 221 of the inner frame 20 restricts the inner box 30 from coming out of the inner frame 20. Of course, in some embodiments, the first limiting part 22 may also be a limiting protrusion, a limiting boss, etc., used to restrict the inner box 30 placed in the inner frame 20 from falling out of the inner frame 20, to ensure that the inner box 30 is stably installed in the inner frame 20, to prevent the inner box 30 from shaking, and to ensure a stable connection between the second connector 35 and the first connector 25 on the inner box 30, and stable electrical conduction.

[0070] As shown in Figure 4, in some embodiments, the inner frame 20 is set as a square, including four sides connected end to end. Generally, a set of opposite side frames can be used as the first limiting part 22 to fix the inner box 30 in the inner frame 20 and ensure that the inner box 30 will not actively come out of the inner frame 20.

[0071] In some embodiments, the inner frame 20 may also be a box-shaped structure.

[0072] In some embodiments, the inner frame 20 is further provided with a second limiting part 24. The second limiting part 24 limits the installation depth of the inner box 30 in the depth direction of the inner frame 20, ensuring that the inner box 30 is installed and positioned in the inner frame 20, avoiding the inner box 30 being inserted too deeply into the inner frame 20, and also avoiding the second connector 35 from being connected to the first connector 25, ensuring that the first connector 25 and the second connector 35 are connected reliably, and extending the service life of the first connector 25 and the second connector 35.

[0073] Referring to Figures 6 and 7, the second limiting part 24 provided on the inner frame 20 can be two supporting sides 241 on the inner frame 20. After the inner box 30 is installed in the inner frame 20, both supporting sides 241 are positioned below the inner box 30, thereby limiting the installation depth of the inner box 30 in the inner frame 20. The second limiting part 24, in conjunction with the first limiting part 22, ensures stable and reliable installation of the inner box 30 in the inner frame 20.

[0074] In addition, the first limiting part 22, in combination with the second limiting part 24, also restricts the installation position of the inner box 30 in the inner frame 20, avoiding problems such as shaking after the inner box 30 is installed in the inner frame 20, and ensuring the stable operation of the panel bottom box 10.

[0075] In some embodiments, the inner box 30 is provided with a fastener 31 for fixing the inner box 30 to the inner frame 20.

[0076] After the inner box 30 is fixed in the inner frame 20, the first limiting part 22 restricts the inner box 30 from coming out of the inner frame 20 by limiting fastener 31.

[0077] When the inner frame 20 is removed from the inner box 30, the fastener 31 is released from the fixation of the first limiting part 22, and the fastener 31 remains intact and is properly retained on the inner box 30.

[0078] The fastener 31, together with the first limiting part 22, makes the inner box 30 fixedly connected to the inner frame 20, ensuring that the inner box 30 is fixed stably and reliably in the inner frame 20.

[0079] The fastener 31, combined with the first limiting part 22, also allows the inner box 30 to be freely installed and removed from the inner frame 20. The inner box 30 can be completely removed from the inner frame 20, enabling the inner box 30 and the inner frame 20 to be reused repeatedly.

[0080] The inner box 30 is shaped to match the inner frame 20. In some embodiments, the inner box 30 is a regular shape, such as a circle, oval, square, triangle, etc. The inner box 30 is generally made of metal or high-strength plastic. The inner box 30 is generally formed by casting, stamping, injection molding, blow molding, thermoforming, compression molding, etc.

[0081] The fastener 31 provided on the inner box 30 is adapted to the first limiting part 22 and is restricted and fixed by the first limiting part 22. At the same time, it is also necessary to ensure that it can be disassembled and detached from the inner frame 20 along with the inner box 30.

[0082] In some embodiments, referring to Figures 8 and 9, the fastener 31 is a buckle 311, which is disposed on the inner box 30 and is adapted to the first limiting part 22 on the inner frame 20. When the inner box 30 is installed in the inner frame 20, the buckle 311 is pressed into the inner frame 20 along with the inner box 30 and is limited and fixed by the first limiting part 22 on the inner frame 20, ensuring the installation of the inner box 30 in the inner frame 20. When the inner box 30 is removed from the inner frame 20, the buckle 311 is released from the limitation of the first limiting part 22 and is removed from the inner frame 20 along with the inner box 30. When the inner box 30 is removed from the inner frame 20, the buckle 311 is intact on the inner box 30, facilitating the reinstallation and fixation of the inner box 30.

[0083] In some embodiments, the fixing member 31 may also be a fixing protrusion or a fixing lug. When the inner box 30 is installed in the inner frame 20, the fixing protrusion or fixing lug is pressed into the inner frame 20 along with the inner box 30, and is limited and fixed by the first limiting part 22 on the inner frame 20, ensuring the installation of the inner box 30 in the inner frame 20. When the inner box 30 is removed from the inner frame 20, the fixing protrusion or fixing lug disengages from the first limiting part 22 and remains intact on the inner box 30, facilitating the reinstallation and fixation of the inner box 30.

[0084] In some embodiments, the inner box 30 is made of metal and high-strength plastic. The inner box 30 itself has a certain degree of toughness, so that when the inner box 30 is fixed in the inner frame 20 or detached from the inner frame 20, the fixing member 31 passes through the first limiting part 22, ensuring that the fixing member 31 and the first limiting part 22 can remain intact after multiple uses.

[0085] Referring to Figures 8 and 9, in some embodiments, the inner box 30 is rectangular, including four sides connected end to end, as well as a bottom surface and a top surface, and the fastener 31 is disposed on the outer side of a set of opposite sides and is adapted to the first limiting part 22.

[0086] In some embodiments, the inner box 30 is further provided with a third limiting part 32, which is adapted to the second limiting part 24 on the inner frame 20. After the inner box 30 is installed in the inner frame 20, the third limiting part 32 is positioned above the second limiting part 24, and together with the second limiting part 24, it limits the depth of the inner box 30 in the inner frame 20, ensuring the installation depth of the inner box 30 in the inner frame 20. Referring to Figures 8 and 9, the third limiting part 32 can be a set of opposing limiting shoulder surfaces 321 on the inner box 30. After the inner box 30 is installed in the inner frame 20, the limiting shoulder surfaces 321 can be positioned on the inner frame 20 above a set of opposing sides of the second limiting part 24.

[0087] In some embodiments, to facilitate the removal of the inner box 30 from the inner frame 20, the inner box 30 is provided with a handle 33 for hand gripping when the inner box 30 is removed from the inner frame 20. The handle 33 is used for hand gripping when the inner box 30 is removed from the inner frame 20. When the inner box 30 needs to be removed from the inner frame 20, the operator can grasp the handle 33 and pull the inner box 30 out of the inner frame 20.

[0088] In some embodiments, the handle position 33 is a pull ring, a pull rod 331, a handle groove, or a grip protrusion, etc.

[0089] In some embodiments, for ease of operation, the handle 33 is a pull rod 331, and the size of the pull rod 331 is suitable for the biological grip of an adult hand. In some embodiments, for easy storage of the pull rod 331, a receiving groove for storing the pull rod 331 is provided on the upper surface of the inner box 30. When the inner frame 20 is removed from the inner box 30, and the pull rod 331 needs to be operated, the pull rod 331 stands up for easy operation. When the pull rod 331 is not needed, it is stored in the receiving groove, reducing the volume of the panel bottom box 10.

[0090] In some embodiments, panel 40 is a control panel, which is provided with switch buttons, adjustment buttons, etc. The upper surface of inner box 30 is provided with a third connector 34 for electrical connection with panel 40. The third connector 34 is electrically connected to a second connector 35. Panel 40 is electrically connected through the third connector 34 and the second connector 35, simplifying the electrical connection between panel 40 and panel base box 10.
