[0029] The following is in conjunction with the appendix Figure 1-8 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.
[0030] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "center", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Furthermore, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art. Therefore, it will not be described in detail in this embodiment.
[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0033] like Figures 1-3 As shown, this utility model relates to an electrical box 100, including: a first housing 1, one end wall of the first housing 1 having at least one first recess 11, the first recess 11 being used for subsequent installation of a cable sleeve 2; in this embodiment, the first housing 1 is a hardware electrical box 100, and two first recesses 11 are provided. In other embodiments, the first recesses 11 can also be set according to the actual situation, which will not be described in detail here.
[0034] like Figure 3 and Figure 6 As shown, at least one cable sheath 2 is provided, and the number of cable sheaths 2 matches the number of first recesses 11. A first slot 21 is formed at the bottom of the cable sheath 2, which engages with the first recesses 11 to connect the cable sheath 2 to the first housing 1. In this embodiment, the depth of the first slot 21 is 5mm, which better secures the entire cable sheath 2 in the first recesses 11, preventing it from falling out.
[0035] By providing a protective sleeve 2, the wire is separated from the first housing 1, preventing the wire from being directly resting on the first housing 1, thus preventing the wire from being scratched and avoiding short circuits that could lead to fire. Simultaneously, the protective sleeve 2 is made of insulating material; in this embodiment, it is made of hard plastic, serving as insulation. This allows the wire to pass through the protective sleeve 2, effectively preventing high-voltage breakdown, improving safety, and providing a safety guarantee for the user.
[0036] Multiple protrusions 22 are provided on both sides of the first slot 21, and each adjacent protrusion 22 is staggered. The staggered interlocking arrangement increases the friction between the wire sleeve 2 and the first housing 1, thereby improving the stability of the connection.
[0037] like Figures 5-7As shown, each adjacent protrusion 22 is 2.5-3mm apart along the length of the first slot 21, and 0.6-0.8mm apart along the width of the first slot 21, ensuring a tight fit between the cable sleeve 2 and the first housing 1. In this embodiment, the protrusions 22 are 2.5mm apart along the length of the first slot 21, and 0.6mm apart along the width of the first slot 21. Since the existing electrical box 100 has a 0.6mm thin metal wall, this application also provides protrusions 22, which are staggered to form a staggered engagement, so that the width between two protrusions 22 is controlled to be 0.6mm, allowing the cable sleeve 2 to be secured to the electrical box 100 with a 0.6mm thin wall.
[0038] One end of the boss 22 is tilted outward. Utilizing the principle of angle and the extensibility of plastic, the cable sleeve 2 will become tighter and tighter as it moves downward along the vertical direction of the first recess 11. When the user needs to disassemble, the cable sleeve 2 will become looser as it moves upward along the vertical direction of the first recess 11. By tilting one end of the boss 22, it makes disassembly and assembly more convenient for the user.
[0039] The top of the cable sleeve 2 has at least one top component 23. In this embodiment, there are two top components 23. The top components 23 are arranged in an I-shape, which not only increases the strength of the cable sleeve 2 and prevents shrinkage and deformation, but also provides a limiting function for the subsequent top cover 6 to cover the first housing 1 and prevent it from falling off.
[0040] The first recess 11 and the wire sheath 2 are U-shaped. The U-shape not only adapts to the shape of the wire, allowing the wire to be better fixed on the wire sheath 2, but also allows the first housing 1 to better distribute stress when subjected to pressure, thereby improving the stability of the first housing 1 and extending its service life.
[0041] like Figures 1-4As shown, a second housing 3 is provided inside the first housing 1. A circuit board 4 and a capacitor 5 are provided inside the second housing 3. A first fixing member 31 is provided outside the second housing 3, and a second fixing member 32 is provided inside the second housing 3. The second housing 3 is connected to the first housing 1 via the first fixing member 31, and the circuit board 4 is connected to the second housing 3 via the second fixing member 32. Specifically, the first housing 1 has a mounting hole 12, into which the first fixing member 31 is inserted to secure the second housing 3. A third fixing member 33 is provided at the other end of the second housing 3, and a through hole 13 is provided at the top of the first housing 1. The user can also insert a locking member into the third fixing member 33 and the through hole 13 for further securing. The first fixing member 31 and the second fixing member 32 are arranged in a triangle, fully utilizing the fixing properties of a triangle to better secure the second housing 3 within the first housing 1. The circuit board 4 has a second slot 41, into which the second fixing member 32 is inserted to secure the circuit board 4. This method of securing the circuit board 4 to the second slot 41 is simple and quick, requiring no additional operations, reducing user steps and speeding up installation. Furthermore, by treating the second housing 3 and the circuit board 4 as a single assembly, maintenance requires minimal disassembly of parts; simply opening the top cover 6 and removing the second housing 3 is sufficient for convenient and quick repairs.
[0042] The second housing 3 is provided with multiple reinforcing ribs 34 to improve the overall strength of the second housing 3. In this embodiment, the second fixing member 32 can also be understood as part of the reinforcing ribs 34. That is, the reinforcing ribs 34 are used to fix the circuit board 4. This not only improves the overall strength of the second housing 3, but also limits the position of the circuit board 4.
[0043] The second housing 3 is made of insulating material. In this embodiment, the insulating material is plastic, that is, the second housing 3 is a plastic inner shell. By using plastic material for the second housing 3, the temperature controller on the power board can be prevented from malfunctioning due to rapid temperature rise caused by heat transfer under high temperature baking. At the same time, the first housing 1 will not directly contact the circuit board 4 due to corrosion, thus avoiding corrosion of the components on the circuit board 4.
[0044] After the circuit board 4 is installed in the second housing 3, the circuit board 4 is 6-8mm lower than the second housing 3 (specifically 6.8mm). When high voltage is converted through the circuit board 4, the plastic second housing 3 will form a shielding space for the circuit board 4, which will prevent current arcing and increase the creepage distance.
[0045] like Figure 8 As shown, this utility model also provides a range hood, which includes: a range hood body 200, and an electrical box 100 is provided on the top of the range hood body 200.
[0046] The main technical effects of this utility model are reflected in the following aspects:
[0047] This electrical box effectively prevents safety accidents caused by short circuits due to scratched power cords.
[0048] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
