The groove assembly is located on the top side. A second long groove is located on one side of the groove assembly, and a retaining groove is located on the bottom side. Multiple press-fit nuts are provided on the ear plates, bottom side, and top side, respectively. The press-fit nuts provide good connection strength, and the grooves facilitate installation and disassembly.
[0008] The PCB bracket is provided with multiple third, fourth, and fifth long slots in multiple directions. Installation and disassembly are convenient and quick.
[0009] At least one grounding stud is fixed on the PCB bracket. This allows leakage current in the electrical system to be conducted to the ground, effectively protecting personal safety.
[0010] Insulating paper is placed between the pillar and the PCB bracket, which enhances the insulation between the PCB motherboard and the bracket.
[0011] The PCB bracket and terminal bracket are connected by rounded arcs at all transition points. Protective features have been implemented to prevent injury to personnel and other components.
[0012] The hand-operated bolts have anti-slip grooves. Their design is reasonable and prevents slippage during installation and disassembly.
[0013] The following beneficial effects can be achieved by using this utility model: This utility model provides an integrated electrical control box structure that can be applied to equipment such as air conditioners and fresh air systems for the installation and wiring of electrical components such as PCB motherboards and terminal blocks. It integrates multiple functions into one unit, simultaneously meeting the installation requirements of PCB motherboards and other electrical components such as terminal blocks. It also provides a channel for wiring and has wide adaptability. The structure is reasonable and has good strength. Furthermore, the structure has limiting and positioning clips and bolt mounting holes, offering advantages such as easy installation and disassembly, good assembly stability, convenient wiring, and high adaptability.

[0023] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] like Figure 1-9 As shown, this utility model is an integrated electrical control box.
[0025] The integrated electrical control box described in this embodiment includes a PCB motherboard 7, which is fixed to a PCB bracket 3 by multiple posts 34. The distance between the PCB motherboard 7 and the PCB bracket 3 is set. The PCB bracket 3 has clips 31 that engage with a terminal bracket 2. The PCB bracket 3 and the terminal bracket 2 are fixedly connected by hand bolts 1, and the connection is open on both sides. The terminal bracket 2 has terminals 6, detachably connected wire clips 4, and fixed wire clamps 5. The terminal bracket 2 has a row of slots 24 for heat dissipation or wire threading. This utility model, with a PCB motherboard 7 and terminals, wire clips, and wire clamps mounted on the terminal bracket 2, realizes the electrical control functions of the host. Figure 8-9 As shown, the terminal bracket of the electrical control box is assembled with the main unit housing by bolts, so that the electrical control box is installed inside the main unit as a whole.
[0026] In this embodiment, the buckle 31 has a bent structure, which is simple and easy to manufacture. The buckle can also be other existing structures, and its actual shape, position and size can be adjusted as needed.
[0027] The PCB bracket 3 is provided with multiple pillars 34. In this embodiment, there are 6 pillars. In practice, the number, specifications and positions of the pillars 34 can be adjusted as needed for the PCB motherboard 7 to be assembled onto the PCB bracket 3. A certain height ensures the safety of the assembly, and a certain number ensures the stability of the installation.
[0028] The terminal bracket 2 is provided with several circular through holes for the assembly of wire clamps, wire clips, etc. The position and size of the through holes can be adjusted according to actual needs.
[0029] In addition to the above-mentioned fixing functions, the terminal bracket 2 can also be used to fix the positions of other electrical components as needed. Not all of them are listed here, such as antenna mounting holes. Wiring labels can also be pasted on it.
[0030] Furthermore, a first elongated groove 22 is provided on one side of the terminal bracket 2, which engages with a snap-fit 31 for positioning and limiting the installation of the PCB bracket 3 and the terminal bracket 2. Outwardly extending ear plates 26 are provided at both ends of the front side, with the ear plates 26 spaced from the bottom side, and are used for fixing and installing the entire electrical control box. A slot group 24 is located on the top side; a second elongated groove 25 is provided on one side of the slot group 24, which can be used for wire threading or heat dissipation. A slot 23 is provided on the bottom side for engaging the wiring terminal 6. Multiple rivet nuts 21 are provided on the ear plate 26, the bottom side, and the top side.
