[0041] like Figures 1 to 5 As shown, this embodiment provides a junction box that effectively prevents electric shock accidents and offers high safety. The junction box includes a mounting base 1 and a door 2. The mounting base 1 is provided with a wire threading slot 111. Two doors 2 are rotatably positioned within the wire threading slots 111. Closing the doors 2 blocks the slots 111, while rotating the doors 2 opens them. The doors 2 are provided with a connecting portion 21, which is used to securely connect to the switch panel via fasteners.

[0042] The usage of the junction box is as follows: Figure 1 and Figure 2 As shown, when the switch panel is not installed, the two doors 2 are closed to block the notch of the wire groove 111 of the mounting base 1 to prevent the pre-buried wires from being exposed, avoid accidents of electric shock to personnel, and improve the safety performance of the junction box. Figure 3 and Figure 4 As shown, when the switch panel needs to be installed, the two doors 2 are rotated to open the notches of the wire grooves 111, which facilitates the electrical connection of the pre-buried wires to the switch panel. The switch panel is fixedly connected to the connecting portion 21 on the door 2 by fasteners, which is convenient and quick to install and has a stable and reliable connection.

[0043] Specifically, the mounting base 1 includes a mounting tube 11, the inner side wall of which is enclosed to form a threading groove 111. The two door bodies 2 are respectively rotatably mounted on the inner side wall of the mounting tube 11. The mounting tube 11 is used to be embedded in the mounting groove on the wall panel 100, and the outer side wall of the mounting tube 11 is in contact with the inner side wall of the mounting groove on the wall panel 100. The threading groove 111 is roughly a square groove. To maintain its appearance, the four corners of the square groove are all rounded. The left and right sides of the two door bodies 2 that are away from each other are rotatably connected to the inner side wall of the mounting tube 11. The upper and lower sides of the two door bodies 2 have no direct connection with the inner side wall of the mounting tube 11, thereby realizing the door opening and closing function when the two door bodies 2 rotate.

[0044] Further, if Figure 3 As shown, the door body 2 and the inner sidewall of the mounting tube 11 are rotatably connected via a flexible portion 23. The flexible portion 23 can be integrally formed with the door body 2 and the mounting tube 11, facilitating easy processing and manufacturing. The flexible portion 23 is thin and made of a soft, flexible material, allowing for easy deformation under load, thereby achieving a rotatable connection between the door body 2 and the mounting tube 11. Of course, in other embodiments, hinges or other structures can also be used to achieve a rotatable connection between the door body 2 and the mounting tube 11.

[0045] Since the sidewall of the mounting tube 11 is relatively thin, a plurality of first reinforcing ribs 112 are provided on the outer sidewall of the mounting tube 11 to ensure the structural strength of the mounting tube 11. The first reinforcing ribs 112 can extend along the height direction of the mounting tube 11, and the ends of the first reinforcing ribs 112 are chamfered to prevent scratches on operators.

[0046] Specifically, the mounting base 1 also includes a mounting frame 12 connected to the mounting tube 11. The mounting frame 12 is sleeved onto the outer wall of the mounting tube 11. The mounting frame 12 is used to abut against the front side of the wallboard 100 to limit the installation position of the mounting tube 11 on the wallboard 100. The mounting frame 12 can be integrally formed with the mounting tube 11 or separately provided. When the mounting frame 12 and the mounting tube 11 are separately provided, the mounting frame 12 and the mounting tube 11 can have an interference fit. The four corners of the mounting frame 12 are respectively rounded to prevent scratches on the operator.

[0047] Since the mounting frame 12 is relatively thin, a plurality of second reinforcing ribs 121 are provided on the inner side of the mounting frame 12 to ensure the structural strength of the mounting frame 12. No reinforcing ribs are required on the outer side of the mounting frame 12 to avoid affecting the smooth and beautiful appearance.

[0048] Alternatively, as Figure 2 and Figure 4As shown, a limit plate 22 is provided on the door body 2. When the door body 2 is rotated to abut against the inner side wall of the mounting tube 11, the limit plate 22 can abut against the rear side of the wall panel 100. The limit plate 22 is perpendicular to the door body 2, and the wall panel 100 is clamped between the limit plate 22 and the mounting frame 12, ensuring the stability and reliability of the entire junction box. A plurality of third reinforcing ribs 221 can also be provided on the limit plate 22 to strengthen the structural strength of the limit plate 22. The third reinforcing rib 221 can be a triangular plate structure, with one right-angled side of the triangular plate structure connected to the door body 2 and the other right-angled side connected to the limit plate 22. To facilitate processing and manufacturing, the third reinforcing rib 221 can be integrally formed with the limit plate 22.

[0049] Specifically, if Figure 5 As shown, the connecting portion 21 includes an enclosing portion 211 and a raised portion 212 protruding from the door body 2. The enclosing portion 211 in the shape of an arch bridge forms an enclosing space 2111. The raised portion 212 is located in the enclosing space 2111. The raised portion 212 is provided with an arc-shaped groove 2121. The arc-shaped groove 2121 and the enclosing portion 211 are arranged to form a cylindrical channel. The cylindrical channel is used to pass fasteners. The inner wall of the cylindrical channel can be provided with threads to facilitate threaded engagement with fasteners such as screws. The enclosing portion 211 and the raised portion 212 can be injection molded integrally with the door body 2, respectively. The processing is simple and convenient for batch processing. The enclosing portion 211 and the raised portion 212 extend respectively along the width direction of the door body 2, so that after the door body 2 is rotated later, the cylindrical channel is directly opposite the fastener to be connected. The two ends of the enclosing portion 211 are rounded transitionally processed to ensure beauty while avoiding scratching the operator.

[0050] To facilitate demoulding after the connection portion 21 is injection molded, optionally, as Figure 2 As shown, the door body 2 is provided with a forming groove 24, which is connected to the surrounding space 2111. In this embodiment, the forming groove 24 is in the shape of an elongated strip, and each door body 2 has two forming grooves 24, which are respectively located on both sides of the raised portion 212.

[0051] To facilitate the operator to observe the degree of tightening of the fastener in the surrounding space 2111, an observation port 2112 is optionally provided on the surrounding portion 211, and the observation port 2112 is connected to the surrounding space 2111. In addition, the observation port 2112 can also serve as a molding hole to facilitate demolding of the surrounding portion 211 after injection molding is completed.

[0052] Optionally, a connecting strip 25 is connected between the two door bodies 2. When the switch panel is not installed, the two door bodies 2 are connected and closed by the connecting strip 25 to block the notch of the wire threading groove 111 of the mounting base 1 to prevent children from accidentally opening the door body 2. When the switch panel needs to be installed, before rotating the two door bodies 2, it is necessary to first cut or cut the connecting strip 25 between the two door bodies 2. The connecting strip 25 can be integrally formed with the two door bodies 2 for easy processing and manufacturing. Two connecting strips 25 can be arranged at intervals along the height direction, which can ensure that the connection strength between the two door bodies 2 is large enough to prevent the door body 2 from being accidentally opened, and can also ensure that the connecting strip 25 is thin enough to be easily cut or cut.

[0053] The junction box provided in this embodiment has two doors 2 that are closed when the switch panel is not installed to block the notch of the wire groove 111 of the mounting base 1, preventing the pre-buried wires from being exposed, avoiding accidents of electric shock to people, and improving the safety performance of the junction box. When the switch panel needs to be installed, the two doors 2 are rotated to open the notch of the wire groove 111 to facilitate the electrical connection of the pre-buried wires to the switch panel. The switch panel is fixedly connected to the connecting portion 21 on the door 2 by fasteners. The installation is convenient and quick, and the connection is firm and reliable.

[0054] This embodiment also provides a lighting switch, including a switch panel and the above-mentioned junction box. The switch panel is fixedly connected to the connecting portion 21 of the junction box by fasteners, which has high safety, simple structure and easy operation.
