[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0024] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.
[0025] In modern building equipment, especially in the atrium unit of an air conditioning system, the assembly of the electrical box is crucial for system safety, stability, and ease of maintenance. The primary function of the atrium unit's drain pan is to collect and direct condensate and other potential liquids to prevent them from entering the electrical components, thereby preventing safety hazards such as short circuits and corrosion. During installation, the electrical box is secured with screws driven into the drain pan. The box includes a mounting plate for the mainboard, an information module, a power module, and a wiring terminal block for securing the motor cables. Each mounting plate and terminal block are secured to the drain pan with screws. Since each module corresponds to a mounting plate, each mounting plate requires multiple screws, resulting in a significant number of screws required to secure the box. Furthermore, existing electrical boxes typically require multiple wire clips for routing wiring. Due to the large number of circuits within the box, the number of wire clips required requires a corresponding number of installations. This requires multiple mounting plates and wire clips to be installed, making the installation and removal process cumbersome.
[0026] like Figure 1-5 As shown, the utility model proposes a mainboard mounting plate, which includes: an assembly plate 21 for mounting panels and a wire-passing plate 5 connected to one side of the assembly plate 21, the wire-passing plate 5 covers the water receiving tray 3, and a wire-passing slot 6 is provided between the assembly plate 21 and the wire-passing plate 5, and the assembly plate 21 and the wire-passing plate 5 are integrally formed.
[0027] Assembly plate 21 sequentially comprises: a power wiring area, a signal wiring area, and a motherboard mounting area. The power wiring area is used to mount power wiring components, the signal wiring area is used to mount signal connectors, and the motherboard mounting area is used to mount the motherboard. The power wiring area is adjacent to the wire board 5. Wire slots 6 are provided between the wire board 5 and assembly plate 21 in the power wiring area. The circuitry in the power wiring area is routed from the wire slots 6 to the wire board 5. In this embodiment, three wire slots 6 are provided between assembly plate 21 and the wire board 5.
[0028] The assembly plate 21 and the wire-passing plate 5 are integrally formed. This design improves the stability and durability of the overall structure and reduces the risk of failure due to loose or detached components. At the same time, the integral molding also simplifies the installation process, eliminating the need for excessive linking structures and improving installation efficiency. By providing a wire-passing slot 6 between the assembly plate 21 and the wire-passing plate 5, the direction of the line is effectively managed, avoiding the situation of disorganized cables. This not only improves the aesthetics, but also reduces the obstruction of air flow by the cables, which is beneficial to heat dissipation.
[0029] In a further embodiment, three cable routing slots 6 are provided at the other end of the assembly plate 21. The addition of these slots provides more cable access throughout the entire mainboard mounting plate. This facilitates better cable management and organization, particularly in complex systems requiring numerous cables. Providing more cable routing slots ensures neat and orderly routing of cables, reducing cable clutter and entanglement, and improving system cleanliness and maintainability.
[0030] In a further embodiment, vertical plates are respectively provided at one end of the assembly plate 21 and between the assembly plate 21 and the wire-passing plate 5 , and notches are provided on the vertical plates as wire-passing slots 6 .
[0031] The wire slot 6 includes: a guide portion and a clamping portion. An inverted triangular notch is provided at the upper edge of the vertical plate as a guide portion. The clamping portion is rectangular and located below the guide portion, and is connected to the tip of the bottom of the guide portion. After the line enters the guide portion from the upper edge of the guide portion, it is clamped into the clamping portion through the tip of the guide portion. Since the guide portion is in an inverted triangular shape, its tip portion is relatively narrow, so after the line is clamped into the clamping portion through the tip portion, the line is not easy to fall out of the clamping portion.
[0032] The guide section is designed as an inverted triangle with no upper edge. This design allows the circuit to easily enter the guide section from the upper edge. The inverted triangle shape naturally guides the circuit down its hypotenuse until it reaches the tip at the bottom. As the inverted triangle tapers to the tip, the circuit is gradually compressed and guided as it descends, allowing for a smooth transition to the clamping section. The clamping section is located below the guide section and connects to the bottom tip of the guide section. When the circuit passes through the guide tip, the narrow tip secures it firmly within the clamping section. Due to the inverted triangle shape and the relatively narrow tip of the guide section, the circuit experiences a strong physical clamping force once it enters the clamping section. This clamping force effectively prevents the circuit from falling out of the clamping section due to vibration or external forces. The combination of the inverted triangle guide section and the rectangular clamping section creates a form-locking mechanism. This mechanism makes it difficult for the circuit to be removed from the clamping section once it is in the clamping section, ensuring a stable and secure connection.
[0033] In a further embodiment, a wire pressing plate 4 is provided on the wire passing plate 5 . The wire pressing plate 4 is plate-shaped and arranged on the wire passing plate 5 . The wire pressing plate 4 confines the power line between the wire passing plate 5 and the wire pressing plate 4 .
[0034] The plate-shaped wire clamp 4, mounted on the wire guide plate 5, effectively confines the power cord between the wire guide plate 5 and the wire clamp 4, ensuring the stability and security of the wiring. This design prevents safety hazards caused by loosening or falling wires during use. With the wire clamp 4 in place, the power cords are neatly arranged on the wire guide plate 5, preventing crossover and entanglement between wires and reducing the risk of electrical failures caused by line interference.
[0035] Specifically, both ends of the wire pressing plate 4 are connected to the wire passing plate 5 by screws, and the line is located in the middle of the wire pressing plate 4. In another embodiment, one end of the wire pressing plate 4 is connected to the wire passing plate 5, and the other end is used for pressing the wire. In this embodiment, the wire pressing plate 4 and the wire passing plate 5 are an integrated structure.
[0036] In a further embodiment, the line passing area is provided with a buckle 7 for limiting the position of the line. The buckle 7 is in a right angle shape, with one side vertically connected to the box body of the line passing area and the other side parallel to the box body of the line passing area.
[0037] One side of the right-angle buckle 7 is vertically connected to the box body of the line passing area, and the other side is parallel to the box body of the line passing area. This design can effectively limit the position of the line.
[0038] In a further embodiment, a retaining strip 8 is spaced along each side of the assembly plate 21, creating a gap between the retaining strip 8 and the electrical box 2 that serves as a cable duct. The retaining strip 8 is plate-shaped, with one end connected to the assembly plate 21 and the other end having a retaining block protruding toward the electrical box 2. Because the assembly plate 21 is mounted on the motherboard, wiring must bypass the motherboard during operation. Therefore, a cable duct is provided between the assembly plate 21 and the electrical box 2 for routing.
[0039] By providing clips 8 on both sides of the mounting plate 21 and forming a cable duct between the mounting plate 21 and the electrical box 2, a clear, direct path is provided for the cables. This design allows the cables to bypass the mainboard, eliminating the need for complex routing above or below the mainboard. This reduces the space occupied by the cables around the mainboard, prevents interference with other components on the mainboard, and improves the system's neatness and reliability.
[0040] The present invention further provides a ceiling unit 1, which includes the electrical box 2 structure of the present invention.
[0041] Three cable routing slots are located between the assembly plate and the cable routing plate: for the aftermarket power cable, the motor cable and electric heater cable, and the temperature sensor cable. Three cable routing slots are located on the right side of the assembly plate: for the air sweep motor cable, the communication cable, and the water pump cable.
[0042] The electrical box comprises a box body and an electrical box cover. The mainboard mounting plate is arranged in the box body, and the electrical box cover is arranged on the box body to cover all the inlet and outlet wires.
[0043] Install the electrical box on the water tray in the skylight. Pass the aftermarket power cable through the wire clamp plate and then snap it into the wire slot between the assembly plate and the wire plate. Clip the motor cable and electric heater cable at the two clips and then snap it into the wire slot between the assembly plate and the wire plate.
[0044] After the temperature sensor cable is inserted into the cable duct between the mainboard mounting plate and the electrical box, it is inserted into one of the cable ducts on the right side of the mainboard mounting plate. The motor cable is inserted into a cable duct between the assembly plate and the cable duct. The communication cable passes through the water tray and then into the wiring duct on the right side of the mainboard mounting plate. The water pump cable is inserted into the cable duct formed by the rotary mounting plate and the electrical box.
[0045] Compared with the prior art, the present invention proposes a mainboard mounting plate, which is installed in the electrical box 2. The mainboard mounting plate includes an assembly plate 21 for mounting panels and a wire-passing plate 5 connected to the side of one end of the assembly plate 21. A wire-passing slot 6 is provided between the assembly plate 21 and the wire-passing plate 5, and the assembly plate 21 and the wire-passing plate 5 are integrally formed. This design improves the stability and durability of the overall structure. At the same time, the integral forming also simplifies the installation process, does not require excessive link structures, and improves installation efficiency.
