Description

Technical Field

[0001] This utility model belongs to the field of electrical engineering technology, specifically relating to a junction box for municipal electrical engineering. Background Technology

[0002] A junction box is a type of connection for electrical wiring. It can be used to label branch lines and provides a convenient port for wiring and tracing. Junction boxes used in municipal electrical engineering are usually installed outdoors. Long-term exposure to wind and rain will cause excessive dust or dirt to accumulate on the surface of the junction box. When workers open the junction box to check the internal wiring connections, dust or dirt will be brought into the junction box. Over time, the accumulation of dust or dirt inside the junction box can cause poor contact at the terminals of the connecting wires, which can easily lead to fire or short circuits, affecting the normal power supply of surrounding residents.

[0003] According to the public announcement number CN220857552U, a junction box for municipal electrical engineering is disclosed. This technology discloses "a technical solution including a mounting base, an external mounting mechanism for the mounting base, and two telescopic rods, which has the technical effect of enabling quick disassembly and facilitating maintenance and protection by workers".

[0004] In this existing design, the installation is achieved through the cooperation of the mounting base, telescopic rod, push block, connecting block, spring, push rod, positioning rod and box. However, since the existing device only uses a shielding method to block water and dust, the protection is not strong. This may cause dust or water to fall into the box, which may easily cause fire or short circuit, affecting people's normal use of electricity.

The box's position is limited, making it easier to fix. An insulating sleeve is provided to prevent fires caused by damaged or crossed wires. An inlet slot allows wires to enter. For details of the operation, refer to "CN220857552U discloses a junction box for municipal electrical engineering". However, existing devices only provide shielding against water and dust, which is not very effective. This may cause dust or water to enter the box, potentially leading to fires or short circuits and affecting people's normal electricity use. To solve this technical problem, a flip-over protective component 2 and a waterproof component 3 are added to this design.

[0032] Furthermore:

[0033] like Figures 1 to 3 As shown:

[0034] Based on the above: The surface of the junction box body 1 is provided with a flip protection component 2.

[0038] In an optional embodiment, a sealing ring 24 is fixedly connected to the surface of the cover 23, and the sealing ring 24 is slidably connected to the junction box body 1.

[0039] In this embodiment: Since a sealing ring 24 is fixedly connected to the surface of the cover 23, and the sealing ring 24 is slidably connected to the junction box body 1, this design can prevent dust and water from entering the interior of the junction box body 1.

[0044] Furthermore:

[0045] like Figure 5 As shown:

[0046] In an optional embodiment, the surface of the protective plate 212 is symmetrically threaded with threaded rods 215, each threaded rod 215 penetrating the surface of the protective plate 212 and rotatably connected to a pressure plate 216.

[0048] It should be noted that the lower surface of the protective plate 212 is corrugated sponge.

[0049] Furthermore:

[0050] like Figures 4 to 5 As shown:

[0051] In an optional embodiment, an electromagnetic interference shield 217 is also installed on the inner surface of the junction box body 1.

[0052] In this embodiment: because an anti-electromagnetic interference sheet 217 is also installed on the inner surface of the junction box body 1, this design allows the wires to work normally without interference through the anti-electromagnetic interference sheet 217.

[0053] Furthermore:

[0054] like Figures 1 to 7 As shown:

A nut 33 is threaded onto the extended end of each connecting bolt 32. Wire grooves 34 are provided on the surface of each connecting bolt 32. This design enhances the waterproof and dustproof effect inside the junction box body 1, preventing the accumulation of dust or dirt inside the junction box body 1 over a long period or water ingress, which could cause poor contact at the wire terminals, potentially leading to fire or short circuits and affecting the normal electricity use of surrounding residents.

[0057] It should be noted that both the connecting bolt 32 and the nut 33 are made of rubber.

[0058] Furthermore:

[0059] like Figures 1 to 7 As shown:

[0060] In an optional embodiment, each end of the connecting bolt 32 away from the sealing ring 31 is fixedly connected to a mounting block 35, and each surface of the mounting block 35 is symmetrically slidably connected to a clamping block 37. Each surface of the clamping block 37 is symmetrically fixedly connected to a limit spring 36, and each end of the limit spring 36 away from the clamping block 37 is fixedly connected to the mounting block 35.

[0061] In this embodiment: because the end of the connecting bolt 32 away from the sealing ring 31 is fixedly connected to the mounting block 35, the surface of the mounting block 35 is symmetrically slidably connected to the clamping block 37, the surface of the clamping block 37 is symmetrically fixedly connected to the limit spring 36, and the end of the limit spring 36 away from the clamping block 37 is fixedly connected to the mounting block 35, this design can flexibly clamp the connection between the wire and the mounting block 35, avoiding friction between the components that could damage the wire, reduce its service life, or even cause safety hazards.

[0062] Working principle: A connecting block 21 is symmetrically fixedly connected to one side surface of the junction box body 1. A fixing block 22 is rotatably connected to the opposite side surface of the connecting block 21. A cover 23 is fixedly connected to the surface of the fixing block 22. A support block 26 is symmetrically fixedly connected to one side surface of the junction box body 1. A flip plate 27 is rotatably connected to the surface of the support block 26. A retaining ring 28 is rotatably connected to the surface of the flip plate 27. A retaining plate 29 is slidably connected to the end of the retaining ring 28 away from the flip plate 27. The retaining plate 29 and the cover 23 are fixedly connected. Wire openings 25 are also symmetrically provided on the surface of the junction box body 1. This design allows for protection of the interior of the junction box body 1 through the cover 23, and facilitates the fixing and opening of the cover 23 by personnel.

This design, by further installing a protective plate 212 inside the junction box body 1, strengthens the protection of the interior of the junction box body 1. The protective plate 212 is symmetrically threaded onto the surface of the protective plate 212. Both the threaded rod 215 and the wire rod 215 penetrate the surface of the protective plate 212 and are rotatably connected to the pressure plate 216. This design allows the wires connected inside the junction box body 1 to be fixed via the pressure plate 216. Since an anti-electromagnetic interference plate 217 is also installed on the inner surface of the junction box body 1, this design allows the wires to work normally without interference. A sealing ring 31 is installed inside the wire opening 25, and a connecting bolt 32 is threaded onto the surface of the sealing ring 31. One end of each connecting bolt 32 penetrates the surface of the junction box body 1 and extends into the interior of the junction box body 1. Nuts 33 are threaded onto the extended ends of each connecting bolt 32. Wire grooves 34 are formed on the surface of each connecting bolt 32. This design allows... To enhance the waterproof and dustproof performance of the junction box body 1, the design prevents dust or dirt from accumulating inside the junction box body 1 over time, or water ingress, which could lead to poor contact at the wire terminals, potentially causing fires or short circuits and affecting the normal electricity supply of surrounding residents.
