Description

Technical Field

[0001] This utility model relates to the field of electrical control box technology, and in particular to an electrical control box assembly and an air conditioner. Background Technology

[0002] The indoor unit electrical control box of an air conditioner is the core component that houses the circuit boards, electrical components, and connecting wires. Its design directly affects the stability and safety of the air conditioner's operation. Currently, commercially available air conditioner indoor unit electrical control boxes typically use simple openings for wiring harnesses to pass through, enabling the connection between the internal and external circuits.

[0003] However, this traditional wiring method has obvious drawbacks:

[0004] First, the wiring harness passes directly through the opening, and there is often a large gap between the opening and the wiring harness, which results in poor sealing of the electrical control box. Dust and moisture are likely to enter the box directly through the gap, causing corrosion or short circuit risk to the internal precision electrical components.

[0005] Secondly, the tangled arrangement of multiple wires passing through the openings not only makes installation and subsequent maintenance difficult, but also poses a safety hazard, as flames or high-temperature gases may escape rapidly through these gaps in the event of an internal electrical fault. Utility Model Content

[0006] In view of the shortcomings of the prior art, the present invention provides an electrical control box assembly and an air conditioner, which solves the problems of poor sealing and inability to manage wires in the prior art electrical control box.

[0007] On the one hand, according to the embodiments of this utility model, the present utility model adopts the following technical solution:

[0008] An electrical control box assembly, comprising:

[0009] The box body has a wire receiving plate on its side, and the wire receiving plate has a wire receiving groove. The end of the wire receiving groove extends through to the inside of the box body.

[0010] The main cover has a secondary cover, and the main cover and the secondary cover are respectively fastened to the box body and the receiving plate;

[0011] The baffle is equipped with a fixing component for fixing the baffle to the cable tray, and the baffle also has multiple cable routing ports for installing cables.

[0012] Preferably, the fixing component includes an insert block disposed on the baffle, and the wire receiving groove has a mounting hole that penetrates the wire receiving plate, and the insert block is engaged with the mounting hole.

[0013] Preferably, the insert is an elastic structure, and the end of the insert is provided with a locking block, so that when the insert passes through the mounting hole, the locking block engages with the opening of the mounting hole.

[0014] Preferably, the locking block is wedge-shaped, and the larger end of the wedge is connected to the insertion block.

[0015] Preferably, the wiring port has a U-shaped opening structure.

[0016] Preferably, the height of the baffle is the same as the depth of the groove.

[0017] Preferably, the inner side of the cable tray has an installation groove, and the baffle is slidably engaged with the installation groove.

[0018] Preferably, both the sub-cover and the line plate are provided with connection holes, and the two connection holes correspond to each other.

[0019] Preferably, a limiting block is provided on the inner side of the main cover, and the limiting block is engaged with the inner side of the box body.

[0020] On the other hand, according to the embodiments of this utility model, the present utility model also adopts the following technical solutions:

[0021] An air conditioner, including an electrical control box assembly.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By setting independent cable trays and baffles on the side of the box, the traditional method of directly opening holes in the box wall is changed. The cable routing ports on the baffles can more closely match the size and quantity of the cable harnesses. This not only facilitates the identification, disassembly, and maintenance of specific cable harnesses during later maintenance, but also reduces the redundant gaps between the cable harnesses and the outlets. Dust and moisture are difficult to enter the box through the effectively sealed cable routing ports, thus protecting the internal precision electrical components and reducing the risk of corrosion and short circuits. Moreover, when an electrical fault occurs inside the box and generates open flames or high-temperature gases, the physical isolation formed by the significantly reduced or even sealed cable routing gaps effectively prevents the flames from escaping quickly and igniting other components, providing sufficient time for handling.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0033] This utility model embodiment proposes an electrical control box assembly, including:

[0034] Box 1, the side of box 1 is provided with a wire receiving plate 101, the wire receiving plate 101 is provided with a wire receiving groove 102, the end of the wire receiving groove 102 extends through to the inside of box 1;

[0035] Main cover 2, main cover 2 is provided with secondary cover 201, main cover 2 and secondary cover 201 are respectively fastened to box body 1 and receiving plate 101;

[0036] The baffle 3 is provided with a fixing member for fixing the baffle 3 to the cable tray 102, and the baffle 3 is also provided with multiple cable routing ports 301 for installing cables.

[0037] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, by setting an independent cable tray 101 and baffle 3 structure on the side of the box 1, the wire harness inside the box 1 is led out to the outside of the box 1 through the cable tray 102, which changes the traditional method of directly opening holes in the box wall. The cable routing port 301 on the baffle 3 can more closely match the size and quantity of the wire harness. This not only facilitates the identification, disassembly and maintenance of specific wire harnesses during later maintenance, but also reduces the redundant gap between the wire harness and the outlet. Dust and moisture are difficult to enter the inside of the box 1 through the effectively sealed cable routing port 301, thereby protecting the internal precision electrical components and reducing the risk of corrosion and short circuits. Moreover, when an electrical fault occurs inside the box 1 and generates open flame or high-temperature gas, the physical isolation formed by the significantly reduced or even sealed cable routing gaps effectively prevents the flame from escaping quickly and igniting other components, giving sufficient time for handling.

[0038] To ensure the stability of the baffle 3 within the cable tray 102, it can be fixedly installed inside using a fastener. This fastener can be a bolted connection structure, secured to the baffle 3 via a threaded connection. Specifically, the structure of the fastener can be optimized, such as... Figure 2 and Figure 3As shown, the fastener includes a plug 302 disposed on the baffle 3. The wire receiving groove 102 has a mounting hole 103 that penetrates the wire receiving plate 101. The plug 302 is snapped into the mounting hole 103. In order to facilitate the installation of the baffle 3, the plug 302 is installed at the bottom of the baffle 3. The installation of the baffle 3 is completed by inserting the plug 302 into the mounting hole 103. The plug 302 and the mounting hole 103 can be an interference fit.

[0039] Further optimization of the fastener structure, such as Figure 2 As shown, an installation groove 105 is provided on the inner side of the cable tray 102. The baffle 3 is slidably engaged with the installation groove 105. The installation groove 105 provides a guide rail for the baffle 3. When installing the baffle 3, simply push the baffle 3 smoothly into the installation groove 105.

[0040] At the same time, such as Figure 3 As shown, the insert 302 is an elastic structure, and the end of the insert 302 is provided with a locking block 303. When the insert 302 passes through the mounting hole 103, the locking block 303 is engaged with the opening of the mounting hole 103. The size of the mounting hole 103 is larger than the size of the insert 302. After the baffle 3 is pushed into the mounting groove 105, there is a deviation between the position of the locking block 303 and the position of the mounting hole 103. Therefore, the insert 302 needs to be bent before the locking block 303 can enter the mounting hole 103. During the continuous pushing of the insert 302, when the locking block 303 passes through the mounting hole 103, the insert 302 is restored and elastic force is applied to the locking block 303, so that the locking block 303 is engaged with the opening of the mounting hole 103, thereby achieving quick fixation of the insert 302.

[0041] Furthermore, the locking block 303 is wedge-shaped, and the large end of the wedge is connected to the insert block 302. Due to the inclined surface of the wedge, when installing the baffle 3, only a downward pressing force needs to be applied to the baffle 3. When the inclined surface of the locking block 303 contacts the edge of the mounting hole 103, it will be subjected to a compressive force, which forces the elastic insert block 302 to deform, thereby allowing the locking block 303 to pass smoothly through the mounting hole 103, which is convenient for operation.

[0042] Specifically, such as Figure 3 As shown, the cable routing port 301 has a U-shaped opening structure, forming an entrance. Operators simply need to insert the cable horizontally into the U-shaped opening of the cable routing port 301 to complete the installation. Furthermore, the specific depth, size, and number of cable routing ports 301 can be customized according to actual needs to meet various usage scenarios. Moreover, the height of the baffle 3 is consistent with the depth of the cable tray 102. When the secondary cover 201 is fastened to the main cover 2, it engages with the cable tray 101, causing the inner side of the secondary cover 201 to abut against the U-shaped opening of the cable routing port 301, thus forming a closed hole structure and ensuring airtightness.

[0043] Specifically, such as Figure 2 As shown, both the sub-cover 201 and the cable tray 101 have connection holes 104. The two connection holes 104 correspond to each other, and screws can be passed through the corresponding two connection holes 104 to fix the sub-cover 201, the main cover 2 and the box body 1.

[0044] Moreover, such as Figure 4 As shown, a limiting block 202 is provided on the inner side of the main cover 2. The limiting block 202 is snapped into the inner side of the box body 1. The snapping cooperation between the limiting block 202 and the inner side of the box body 1 provides physical guidance for the installation of the main cover 2, thereby facilitating installation.

The specific structure of the electrical control box assembly is as described in the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
