Description

Technical Field

[0001] This invention relates to the field of noise reduction and electromagnetic compatibility technology for air conditioner compressors, specifically to an integrated electromagnetic compatibility soundproof enclosure, a compressor, and an air conditioner. Background Technology

[0002] With the miniaturization, compactness, and functional diversification of air conditioning systems, the space for arranging internal components of air conditioners is gradually becoming limited, resulting in relatively little space available for wiring inside the unit. For some air conditioning models with built-in wiring, the wiring typically needs to be introduced from the bottom of the unit, pass through the compressor area, and extend upwards to the area where the electronic control components are located.

[0003] Compressors generate electromagnetic interference during operation. When the wiring harness passes near the compressor, the interference signals generated by the compressor may be transmitted to the area where the electronic control components are located through the wiring harness, thus affecting the overall electromagnetic compatibility performance of the machine. Current technologies typically address this issue by adjusting the wiring harness routing, requiring the wiring harness to be kept away from the compressor, adding ferrite cores to the wiring harness, or adding shielding structures to the outside of the cable. However, these methods require highly skilled installers on-site, and the actual assembly process is easily affected by factors such as wiring space, fixing location, ferrite core placement, and cable fixing method, leading to poor assembly consistency.

[0004] At the same time, such as Figure 1 As shown, the compressor is typically surrounded by a soundproof cover or sound-absorbing cotton to reduce operating noise. After the compressor is encased in soundproofing, the space available for cabling around it is further reduced. Currently, cabling passing through the compressor area often relies on Velcro, waterproofing strips, cable ties, conduits, or other nearby structures for securing it, lacking dedicated cabling routing and securing structures that complement the compressor's soundproofing. This type of securing method has poor stability and consistency; during transport or compressor operation, cabling may shift, loosen, or wear, and may rub against surrounding components.

[0005] Furthermore, when a magnetic ring needs to be added to the wiring harness to suppress electromagnetic interference, the magnetic ring is usually externally mounted on the wiring harness, occupying limited space around the compressor. Due to the lack of stable support and limiting structures, it may sway during transportation or operation, or even collide with side panels, pipelines, or other components. The position and fixing method of the external magnetic ring are also easily affected by assembly operations, further increasing the uncertainty of overall wiring consistency and electromagnetic compatibility performance. Summary of the Invention

[0006] To address the problems in existing technologies, such as the lack of a dedicated cable fixing structure when the engineering line passes through the compressor area, poor consistency of the wiring path, and the easy transmission of electromagnetic interference generated by the compressor to the electrical control area through the engineering line, one objective of this invention is to provide an electromagnetic compatibility cable fixing integrated soundproof cover device. To achieve the above objectives, the present invention adopts the following technical solution: an electromagnetic compatibility-integrated soundproof enclosure device, wherein the soundproof enclosure is disposed around the outer periphery of the compressor; An electromagnetic compatibility (EMC) wiring device is installed on the soundproof enclosure, including a cable tray housing, a shielding component, and a grounding component; The cable tray housing has an open state and a closed state, and in the closed state, it forms a cable routing cavity for accommodating engineering cables. The shielding element is disposed on at least a portion of the inner wall of the wiring cavity, and the grounding element is electrically connected to the shielding element and led out from the outer shell of the cable tray.

[0007] Furthermore, the soundproof enclosure is provided with a mounting part, the cable tray housing is provided with an assembly part that mates with the mounting part, and the electromagnetic compatibility cable fixing device is mounted on the soundproof enclosure through the assembly part.

[0008] Furthermore, the mounting part is a slot located on the outside of the soundproof cover, and the assembly part is inserted into the slot.

[0009] Furthermore, the slot extends along the height direction of the soundproof cover, and the mounting part is inserted into the slot along the extension direction of the slot.

[0010] Furthermore, the cable tray housing includes a first channel wall, a second channel wall, and a plurality of cable tray sidewalls. The first channel wall and the second channel wall are disposed opposite to each other, and the plurality of cable tray sidewalls are respectively connected to the first channel wall and the second channel wall. When the cable tray housing is in a closed state, the first channel wall, the second channel wall, and the plurality of cable tray sidewalls together form the cable routing cavity extending along the length direction of the cable tray housing.

[0011] Furthermore, a first free end is formed on the side of the first groove wall away from the sidewall of the wire trough, and a second free end is formed on the side of the second groove wall away from the sidewall of the wire trough. An opening is formed between the first free end and the second free end to communicate with the wiring cavity. When the wire trough housing is in the open state, the first free end and the second free end are separated from each other so that the engineering wire can be placed into the wiring cavity through the opening. When the wire trough housing is in the closed state, the first free end and the second free end are close to each other so that the engineering wire is confined within the wiring cavity.

[0012] Furthermore, magnetic strips are respectively provided on the first free end and the second free end, and both magnetic strips extend along the length direction of the wiring cavity; when the wire groove shell is in a closed state, the magnetic strips provided on the first free end and the magnetic strips provided on the second free end attract and adhere to each other, so that the first free end and the second free end form a mating connection structure.

[0013] Furthermore, the shielding component is a shielding mesh, which is disposed on the inner side of the cable tray housing and extends along the length direction of the cable routing cavity.

[0014] Furthermore, one end of the grounding component extends into the outer shell of the cable tray and is electrically connected to the shielding mesh, while the other end of the grounding component extends out from the outer shell of the cable tray.

[0015] Furthermore, one end of the grounding component extending out of the outer casing of the wire trough is provided with a grounding connection end, which is used to connect to the grounding positioning point on the compressor, the grounding part of the casing, or the grounding wire of the whole machine.

[0016] Furthermore, a magnetic ring support layer is provided inside the wiring cavity. The magnetic ring support layer is connected to the side of the first groove wall and / or the second groove wall facing the wiring cavity, and is located on the side of the shielding member facing the wiring cavity. The magnetic ring support layer includes at least one support member arranged along the length direction of the wiring cavity. The support member and the wire groove shell together define a mounting position for accommodating the magnetic ring. The magnetic ring is used to be sleeved on the outer periphery of the engineering wire and supported in the mounting position.

[0017] To achieve the above objectives, the present invention also provides a compressor, comprising:

[0018] The compressor body; and The above-mentioned electromagnetic compatibility-integrated soundproof enclosure device with fixed wiring; The soundproof enclosure is arranged around the outer periphery of the compressor body, the electromagnetic compatibility wiring device is disposed on the soundproof enclosure, and the grounding component is electrically connected to or used for electrically connecting to the grounding part of the compressor body.

[0019] Furthermore, the present invention also provides an air conditioner, comprising: chassis; An electronic control component, wherein the electronic control component is disposed within the housing; A compressor, wherein the compressor is disposed within the housing; Engineering lines, the engineering lines being connected to the electronic control components; and The above-mentioned electromagnetic compatibility-integrated soundproof enclosure device with fixed wiring; The soundproof cover is arranged around the outer periphery of the compressor, the engineering wire passes through the wiring cavity formed by the wire trough shell, and the grounding component is connected to the compressor grounding part, the casing grounding part, or the whole machine grounding wire.

[0020] Beneficial effects: 1. By cooperating with the soundproof cover, electromagnetic compatibility wiring device, cable tray shell, shielding component and grounding component, an integrated structure with sound insulation, wiring fixation and shielding grounding functions can be formed around the compressor. This solves the problems of lack of dedicated wiring fixation position, unstable wiring path and easy transmission of electromagnetic interference along the wiring when the engineering line passes through the compressor area. It enables the engineering line to be limited and shielded in the preset wiring cavity, which facilitates the assembly and subsequent maintenance of the engineering line.

[0021] 2. With the installation and assembly parts, the electromagnetic compatibility (EMC) wiring device can be directly installed on the soundproof enclosure, solving the problem that the EMC wiring device needs to be fixed by pipes, cable ties or other nearby structures. This allows the EMC wiring device to form a stable connection with the soundproof enclosure, facilitating the positioning and installation of the EMC wiring device.

[0022] 3. By setting a slot and cooperating with the assembly part, soundproof cover and wire trough shell, the assembly part can be inserted into the slot on the outside of the soundproof cover. This solves the problem of complex connection structure and inconvenient assembly positioning of the electromagnetic compatibility wire fixing device and the soundproof cover. It enables the electromagnetic compatibility wire fixing device to be quickly fixed relative to the soundproof cover, which facilitates the assembly of the whole machine.

[0023] 4. By cooperating with the slots extending along the height of the soundproof enclosure and the assembly parts inserted along the extension direction of the slots, the electromagnetic compatibility wiring device can be arranged along the height of the soundproof enclosure. This solves the problem of lack of vertical wiring guidance when the engineering line passes through the compressor area, enabling the engineering line to form a relatively stable wiring path along the height of the soundproof enclosure, and facilitating the extension and layout of the engineering line from the compressor area to the electrical control area.

[0024] 5. By setting the first groove wall and the second groove wall, and the multiple groove side walls to cooperate with each other, a wiring cavity extending along the length of the groove shell can be formed when the groove shell is closed. This solves the problem that the engineering wires have no dedicated space in the area near the compressor and are easy to be exposed or deviated. It allows the engineering wires to be contained inside the groove shell, which facilitates the centralized arrangement and protection of the engineering wires.

[0025] 6. By cooperating with the first and second free ends, the opening and closing port, and the wiring cavity, the cable tray housing can be opened to allow the engineering cable to be inserted into the wiring cavity through the opening and closing port, and the engineering cable can be confined within the wiring cavity when the cable tray housing is closed. This solves the problems of inconvenient cable threading and easy loosening after fixing, allowing the engineering cable to be quickly inserted and constrained within the cable tray housing, facilitating the installation, replacement, and maintenance of the engineering cable.

[0026] 7. By having two magnetic strips that cooperate with the first and second free ends, the two magnetic strips can be attracted and attached to each other when the cable tray shell is closed. This solves the problems of unstable opening and closing of the cable tray shell and inconvenience of repeated disassembly and assembly. It also forms a reusable connection structure between the first and second free ends, which facilitates the quick fixing of the engineering cable and subsequent maintenance.

[0027] 8. By cooperating with the shielding mesh, the cable tray shell, and the cable routing cavity, the shielding mesh can be set inside the cable tray shell along the length of the cable routing cavity. This solves the problem of lack of shielding protection when the engineering cable passes through the compressor area, and allows the engineering cable to be shielded by the shielding mesh in the cable routing cavity. This facilitates the integrated arrangement of engineering cable routing and electromagnetic shielding in a limited space.

[0028] 9. By cooperating with the grounding component and the shielding mesh and cable tray shell, one end of the grounding component can be electrically connected to the shielding mesh, and the other end can be led out from the cable tray shell. This solves the problem that the shielding mesh is difficult to form a reliable electrical connection with the external grounding structure, and enables the shielding mesh to be connected to the grounding structure through the grounding component, which facilitates the grounding installation of the shielding mesh.

[0029] 10. By cooperating with the grounding connection terminal, grounding component, compressor grounding positioning point, casing grounding part or whole machine grounding wire, the shielding mesh can be connected to the grounding structure through the grounding component. This solves the problems of unclear grounding position of the shielding structure and poor grounding assembly consistency, so that the shielding mesh can obtain a clear grounding connection path, which facilitates the grounding layout and assembly identification of the whole machine.

[0030] 11. By cooperating with the magnetic ring support layer, the first groove wall, the second groove wall, the shielding component, and the wire groove shell, an installation position for accommodating the magnetic ring can be formed in the wiring cavity. This solves the problem of the magnetic ring occupying the space around the compressor and easily shaking or colliding with surrounding components when it is externally hung on the engineering line. It allows the magnetic ring to be set in the wire groove shell along with the engineering line and supported by the support component, which facilitates the positioning, installation, and limiting fixation of the magnetic ring.

[0031] 12. By cooperating with the integrated soundproof enclosure device for electromagnetic compatibility (EMC) wiring, the grounding component, and the grounding part of the compressor body, the soundproof enclosure can be set around the outer periphery of the compressor body, and the EMC wiring device can be fixed on the soundproof enclosure. This solves the problems of the independent soundproof structure and the fixed structure of the engineering line around the compressor, and the unstable layout of the engineering line near the compressor. It enables the compressor to provide a fixed and grounding connection position for the engineering line while having a soundproof structure, which facilitates the wiring harness layout in the compressor area.

[0032] 13. By cooperating with the housing, electrical control components, compressor, engineering cables, and electromagnetic compatibility integrated soundproof enclosure, the engineering cables can be run through the cable tray cavity formed by the cable tray housing, and the grounding component can be connected to the compressor grounding part, housing grounding part, or whole unit grounding wire. This solves the problems of non-standard wiring, insufficient electromagnetic interference protection, and inconvenient grounding connection when the internal engineering cables of the air conditioner pass through the compressor area. It enables the internal engineering cables of the air conditioner to be arranged along the preset path and obtain shielded grounding protection, which facilitates the overall assembly of the air conditioner and the consistency control of wiring.

Detailed Implementation

[0045] To make the objectives, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0048] Example 1 Reference Figure 2 , Figure 3 and Figure 5 This is the first embodiment of the present invention, which provides an integrated electromagnetic compatibility (EMC) wire-fixing soundproof enclosure device that integrates compressor operating noise suppression, engineering wire 300 fixing, and electromagnetic interference signal shielding and grounding. The integrated EMC wire-fixing soundproof enclosure device includes a soundproof enclosure 100 and an EMC wire-fixing device 200. The soundproof enclosure 100 forms a soundproof structure surrounding the compressor; the EMC wire-fixing device 200 forms a structure for accommodating, fixing, and shielding the engineering wire 300, allowing the engineering wire 300 to pass through the compressor area along a predetermined path.

[0049] Specifically, the soundproof enclosure 100 is used to surround the outer periphery of the compressor. The soundproof enclosure 100 can surround at least a portion of the outer periphery of the compressor to block the noise generated during compressor operation. The soundproof enclosure 100 is provided with a mounting part 101, which is used to cooperate with the electromagnetic compatibility wiring device 200 so that the electromagnetic compatibility wiring device 200 can be installed on the soundproof enclosure 100.

[0050] Furthermore, the electromagnetic compatibility wiring device 200 includes a cable tray housing 201, a shielding component 202, and a grounding component 203. The cable tray housing 201 has an open state and a closed state. In the closed state, the cable tray housing 201 forms a wiring cavity for accommodating the engineering cable 300. By providing the cable tray housing 201, it is convenient to arrange the engineering cable 300 along the wiring cavity within the compressor area, reducing the possibility of the engineering cable 300 being loosely laid out around the compressor.

[0051] The shielding component 202 is disposed on at least part of the inner wall of the wiring cavity, and the grounding component 203 is electrically connected to the shielding component 202 and led out from the outer shell 201 of the cable tray. By setting the shielding component 202 and the grounding component 203, it is convenient to form a shielded grounding structure at the wiring path of the engineering line 300, so that the shielding component 202 can be connected to the grounding structure through the grounding component 203.

[0052] Preferably, the cable tray housing 201 is provided with an assembly portion 2011, which cooperates with the mounting portion 101 on the soundproof enclosure 100 to allow the electromagnetic compatibility cable fixing device 200 to be mounted on the soundproof enclosure 100. The mounting portion 101 may be a slot provided on the outside of the soundproof enclosure 100, and the assembly portion 2011 is inserted into the slot. The slot extends along the height direction of the soundproof enclosure 100, and the assembly portion 2011 is inserted into the slot along the extension direction of the slot, thereby allowing the electromagnetic compatibility cable fixing device 200 to be positioned along the height direction of the soundproof enclosure 100.

[0053] Working principle: During assembly, the soundproof cover 100 is placed around the compressor, and the electromagnetic compatibility wiring device 200 is installed on the soundproof cover 100 through the assembly part 2011 and the mounting part 101. During wiring, the engineering wire 300 is placed in the wiring cavity formed by the cable tray housing 201, so that the engineering wire 300 passes through the compressor area along the wiring cavity. When the compressor is running, the soundproof cover 100 blocks the compressor's operating noise, the shielding component 202 forms a shielding structure for the engineering wire 300 in the wiring cavity, and the grounding component 203 connects the shielding component 202 to the grounding structure, thereby reducing the possibility of electromagnetic interference signals being transmitted along the engineering wire 300.

[0054] In summary, by using the soundproof cover 100 and the electromagnetic compatibility wiring device 200 together, the compressor can be soundproofed while providing a dedicated wiring and fixing structure for the engineering line 300. Furthermore, a shielded grounding structure is formed by the shielding component 202 and the grounding component 203, which solves the problems of lack of a dedicated wiring fixing structure, poor wiring path consistency, and insufficient electromagnetic compatibility protection when the engineering line 300 passes through the compressor area in the prior art.

[0055] Example 2 Reference Figure 6 and Figure 9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment further describes the specific structure of the cable tray housing 201 and the implementation of its open and closed states, in order to solve the problem of how the engineering cable 300 can be quickly placed into the cable routing cavity and reliably limited.

[0056] Specifically, the cable tray housing 201 includes a first channel wall 2012, a second channel wall 2013, and a plurality of cable tray sidewalls 2014. The first channel wall 2012 and the second channel wall 2013 are disposed opposite to each other, and the plurality of cable tray sidewalls 2014 are respectively connected to the first channel wall 2012 and the second channel wall 2013. When the cable tray housing 201 is in the closed state, the first channel wall 2012, the second channel wall 2013, and the plurality of cable tray sidewalls 2014 together form a cable routing cavity extending along the length direction of the cable tray housing 201.

[0057] Furthermore, a first free end is formed on the side of the first channel wall 2012 away from the channel side wall 2014, and a second free end is formed on the side of the second channel wall 2013 away from the channel side wall 2014. An opening is formed between the first free end and the second free end, communicating with the wiring cavity. When the channel housing 201 is in the open state, the first free end and the second free end are separated from each other, and the opening is in the open state, allowing the engineering wire 300 to be inserted into the wiring cavity through the opening. When the channel housing 201 is in the closed state, the first free end and the second free end are close to each other, so that the engineering wire 300 is confined within the wiring cavity.

[0058] The first and second free ends are each provided with a magnetic strip 206, both of which extend along the length of the wiring cavity. When the wire trough housing 201 is in the closed state, the magnetic strip 206 at the first free end and the magnetic strip 206 at the second free end attract and adhere to each other, so that the first and second free ends form a mating connection structure, and the wire trough housing 201 remains in the closed state.

[0059] Preferably, the cable tray housing 201 can switch between an open and closed state under the action of external force. By providing a first free end, a second free end, and a magnetic strip 206, it is convenient for operators to open the cable tray housing 201 to insert the engineering wire 300, and it is also convenient to limit the engineering wire 300 after the cable tray housing 201 is closed.

[0060] Working principle: During wiring, the operator separates the first and second free ends, opening the cable tray housing 201. The engineering wire 300 is then inserted into the wiring cavity through the opening. After insertion, the first and second free ends are brought close together, attracting the two magnetic strips 206. The cable tray housing 201 then closes, confining the engineering wire 300 within the wiring cavity by the first tray wall 2012, the second tray wall 2013, and multiple cable tray sidewalls 2014. When adjustment or maintenance of the engineering wire 300 is required, the first and second free ends can be separated again to open the cable tray housing 201.

[0061] In summary, by setting up the first groove wall 2012, the second groove wall 2013, the side wall of the wire trough 2014, the opening and closing port, and the magnetic strip 206 in combination, the wire trough shell 201 can facilitate the quick insertion of the engineering wire 300 when it is open, and limit and fix the engineering wire 300 when it is closed. This solves the problems of inconvenient insertion of the engineering wire 300, insufficient reliability of the closure of the wiring cavity, and inconvenience of later maintenance.

[0062] Example 3 Reference Figure 4 and Figure 7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment further illustrates the specific structure of the shield 202 and the connection relationship with the grounding component 203, so as to solve the problem of how to form a shielded grounding structure when the engineering line 300 passes through the compressor area.

[0063] Specifically, the shielding component 202 is a shielding mesh, which is disposed on the inner side of the cable tray housing 201 and extends along the length of the cable routing cavity. The shielding mesh is located on the outer periphery of the engineering cable 300, and can form a shielding structure for the engineering cable 300 when the engineering cable 300 is placed inside the cable routing cavity.

[0064] Furthermore, one end of the grounding component 203 extends into the cable tray housing 201 and is electrically connected to the shielding mesh, while the other end of the grounding component 203 extends out from the cable tray housing 201. By setting the grounding component 203, it is convenient to extend the shielding mesh out of the cable tray housing 201 and form a connection relationship with the corresponding grounding position.

[0065] The grounding component 203 has a grounding connection end at one end of the lead-out cable tray housing 201. This grounding connection end is used to connect to the grounding positioning point on the compressor, the grounding part of the housing, or the grounding wire of the entire machine. By providing the grounding connection end, it is convenient to assemble and connect the grounding component 203 with the grounding structure, so that the shielding mesh can form a grounding path through the grounding component 203.

[0066] Preferably, when the cable tray housing 201 is in the closed state, the shielding mesh surrounds at least a portion of the outer periphery of the cable 300 to form a shielding structure for the cable 300 within the cable routing cavity. The shielding mesh is electrically connected to the grounding component 203, allowing interference signals received by the shielding mesh to be guided to the grounding structure via the grounding component 203.

[0067] Working principle: After the engineering cable 300 is placed into the cable tray cavity, the shielding mesh is set inside the cable tray housing 201 along the extension direction of the engineering cable 300 and located on the outer periphery of the engineering cable 300. When the compressor is running, electromagnetic interference signals generated near the compressor can be shielded by the shielding mesh. The shielding mesh is connected to the grounding positioning point on the compressor, the grounding part of the casing, or the grounding wire of the whole machine through the grounding component 203, thereby forming a shielded grounding path and reducing the possibility of interference signals being transmitted to the electrical control area along the engineering cable 300.

[0068] In summary, by using the shielding mesh and grounding component 203 together, a shielding and grounding structure corresponding to the routing path of the engineering line 300 can be formed inside the cable tray housing 201. This solves the problems of insufficient electromagnetic interference protection when the engineering line 300 passes through the compressor area and the inconvenience of grounding the shielding structure, enabling the engineering line 300 to obtain shielding protection while being fixed.

[0069] Example 4 Reference Figures 8 to 11 This is the fourth embodiment of the present invention. Unlike the previous embodiment, this embodiment further describes the cooperation structure between the magnetic ring support layer 204 and the magnetic ring 205 to solve the problem of how to stably set the magnetic ring 205 on the engineering line 300.

[0070] Specifically, a magnetic ring support layer 204 is provided inside the wiring cavity. The magnetic ring support layer 204 is connected to the side of the first groove wall 2012 and / or the second groove wall 2013 facing the wiring cavity, and is located on the side of the shield 202 facing the wiring cavity. By providing the magnetic ring support layer 204, a structure for supporting the magnetic ring 205 can be formed inside the wiring cavity, allowing the magnetic ring 205 to be disposed inside the cable tray housing 201.

[0071] Furthermore, the magnetic ring support layer 204 includes at least one support member arranged along the length of the cable routing cavity. The support member, together with the cable tray housing 201, defines a mounting position for accommodating the magnetic ring 205. The magnetic ring 205 is fitted around the outer periphery of the engineering cable 300 and supported within the mounting position. By providing the support member and the mounting position, the magnetic ring 205 is conveniently supported and held in a predetermined position within the cable routing cavity.

[0072] When the engineering line 300 requires the configuration of a magnetic ring 205, the magnetic ring 205 can be fitted around the outer periphery of the engineering line 300 and placed into the wiring cavity along with the engineering line 300. The magnetic ring 205 is supported within the mounting position formed by the magnetic ring support layer 204. By supporting the magnetic ring 205 through the magnetic ring support layer 204, the shaking or displacement of the magnetic ring 205 during transportation or compressor operation vibration can be reduced.

[0073] Preferably, the magnetic ring support layer 204 is disposed within the wiring cavity and located on the side of the shield 202 facing the wiring cavity, allowing the magnetic ring 205 to be disposed inside the cable tray housing 201, rather than being directly attached to the outside of the engineering cable 300. Thus, the magnetic ring 205 and the engineering cable 300 can be together housed and restrained by the cable tray housing 201.

[0074] Working principle: When the engineering cable 300 requires the magnetic ring 205, the magnetic ring 205 is fitted around the outer periphery of the engineering cable 300, and the engineering cable 300 and the magnetic ring 205 are placed together into the wiring cavity of the cable tray housing 201. The magnetic ring 205 is placed in the mounting position defined by the magnetic ring support layer 204 and the cable tray housing 201, and then the cable tray housing 201 is switched to the closed state. After the cable tray housing 201 is closed, the engineering cable 300 is confined within the wiring cavity, and the magnetic ring 205 is supported by the magnetic ring support layer 204 and held in the mounting position.

[0075] In summary, by using the magnetic ring support layer 204, magnetic ring 205, cable tray housing 201, and engineering cable 300 together, a dedicated support position for magnetic ring 205 can be provided in the cable routing cavity. This solves the problems of magnetic ring 205 occupying space around the compressor, being prone to shaking, and having poor layout consistency when externally mounted on engineering cable 300. It also allows magnetic ring 205 to be installed together with engineering cable 300 inside cable tray housing 201, facilitating the installation and positioning of magnetic ring 205.

[0076] Example 5 Reference Figures 8 to 11 This is the fifth embodiment of the present invention. Unlike the previous embodiment, this embodiment further illustrates the positional relationship of the wiring cavity and internal structure of the wire groove housing 201 in the closed and open states.

[0077] Specifically, refer to Figure 8 and Figure 10When the cable tray housing 201 is in the closed state, the first channel wall 2012 and the second channel wall 2013 are close to each other, and the magnetic strips 206 disposed at the first free end and the second free end are attracted and attached to each other. The first channel wall 2012, the second channel wall 2013 and the multiple cable tray side walls 2014 together form a cable routing cavity, the engineering wire 300 is located in the cable routing cavity, the shield 202 is disposed on at least part of the inner surface of the cable tray housing 201, and the magnetic ring support layer 204 is located on the side of the shield 202 facing the cable routing cavity.

[0078] Furthermore, refer to Figure 9 and Figure 11 When the cable tray housing 201 is in the open state, the first channel wall 2012 and the second channel wall 2013 are far apart, and the magnetic strips 206 disposed at the first free end and the second free end are separated from each other, and the opening is in the open state. At this time, the engineering wire 300 can enter or exit the cable routing cavity through the opening, and the shielding member 202 changes position with the open and closed states of the cable tray housing 201.

[0079] During the process of switching the cable tray housing 201 from an open state to a closed state, the first channel wall 2012 and the second channel wall 2013 move from a position away from each other to a position closer to each other, causing the shielding member 202 located inside the cable tray housing 201 to move closer to the engineering cable 300. When the magnetic strips 206 are attracted and attached to each other, the engineering cable 300 is confined within the cable routing cavity, and the shielding member 202 is located on the outer periphery of the engineering cable 300 to form a shielding structure for the engineering cable 300.

[0080] Better Figure 10 and Figure 11 The diagram shows the top cross-sectional structure of the cable tray housing 201 in both closed and open states. Switching between these two states allows for the rapid insertion, positioning, and maintenance removal of the engineering cable 300.

[0081] Working principle: With the cable tray housing 201 open, the opening is open, allowing the engineering wire 300 to be inserted into the wiring cavity. After the engineering wire 300 is inserted, the first channel wall 2012 and the second channel wall 2013 approach each other, and the magnetic strips 206 attract and adhere to each other, closing the cable tray housing 201 and limiting the engineering wire 300 within the wiring cavity. The shielding component 202 is located inside the cable tray housing 201 and on the outer periphery of the engineering wire 300. The grounding component 203 is electrically connected to the shielding component 202 and led out from the cable tray housing 201 to form a shielded grounding path.

[0082] In summary, by using the first groove wall 2012, the second groove wall 2013, the side wall of the wire trough 2014, the shielding component 202, the grounding component 203, and the magnetic strip 206 in combination, the wire trough outer shell 201 can switch between an open state and a closed state. In the closed state, it can simultaneously achieve the limiting fixation and shielding protection of the engineering wire 300, thus solving the problems of separation between the fixing structure and the shielding structure of the engineering wire 300 and poor assembly consistency.

[0083] Example 6 Reference Figure 2 , Figure 3 , Figure 5 and Figure 8 This is the sixth embodiment of the present invention. Unlike the embodiments described above, this embodiment provides a compressor and an air conditioner to illustrate the application of the electromagnetic compatibility-integrated soundproof enclosure device in compressor and air conditioning products.

[0084] Specifically, the compressor includes a compressor body and the integrated electromagnetic compatibility (EMC) wiring and soundproof enclosure device as described in any of the above embodiments. The soundproof enclosure 100 surrounds the outer periphery of the compressor body, the EMC wiring device 200 is disposed on the soundproof enclosure 100, and the grounding component 203 is electrically connected to or used for electrical connection to the grounding portion of the compressor body. By providing this integrated EMC wiring and soundproof enclosure device, an integrated structure for sound insulation, wiring, and shielding grounding can be formed around the outer periphery of the compressor body.

[0085] Furthermore, the air conditioner includes a casing, electronic control components, a compressor, an engineering cable 300, and the electromagnetic compatibility-integrated soundproof enclosure device described in any of the above embodiments. The compressor is housed within the casing, the electronic control components are housed within the casing, and the engineering cable 300 is connected to the electronic control components. The soundproof enclosure 100 surrounds the outer periphery of the compressor, the engineering cable 300 passes through the wiring cavity formed by the cable tray housing 201, and the grounding component 203 is connected to the compressor grounding part, the casing grounding part, or the overall unit grounding wire.

[0086] The electromagnetic compatibility (EMC) wiring device 200 is mounted on the soundproof enclosure 100 via an assembly part 2011 cooperating with a mounting part 101 on the soundproof enclosure 100. When the engineering cable 300 passes through the compressor area, it can be accommodated in the wiring cavity formed by the cable tray housing 201. The shielding member 202 is disposed on at least part of the inner wall of the wiring cavity, and the grounding member 203 is electrically connected to the shielding member 202 and led out to the corresponding grounding position.

[0087] Preferably, when the engineering line 300 requires the magnetic ring 205, the magnetic ring 205 is fitted around the outer periphery of the engineering line 300 and supported within the mounting position formed by the magnetic ring support layer 204. By placing the magnetic ring 205 inside the cable tray housing 201, the situation where the magnetic ring 205 is directly hung outside the engineering line 300 can be reduced.

[0088] Working Principle: During compressor or air conditioner assembly, a soundproof cover 100 is placed around the compressor body or its outer perimeter, and an electromagnetic compatibility (EMC) wiring device 200 is installed on the soundproof cover 100. Then, the cable tray housing 201 is opened, and the engineering wire 300 is placed into the wiring cavity through the opening. As needed, a magnetic ring 205 is placed in the mounting position formed by the magnetic ring support layer 204. After the engineering wire 300 is arranged, the cable tray housing 201 is closed, and the magnetic strips 206 adhere to each other, confining the engineering wire 300 within the wiring cavity. The grounding component 203 is connected to the compressor grounding part, the casing grounding part, or the overall grounding wire, forming a grounding path for the shielding component 202. When the compressor is running, the soundproof cover 100 blocks compressor operating noise, the shielding component 202 forms a shielding structure for the engineering wire 300, and the grounding component 203 connects the shielding component 202 to the grounding structure, thereby reducing the possibility of electromagnetic interference signals being transmitted along the engineering wire 300.

[0089] In summary, by applying the integrated electromagnetic compatibility (EMC) wire-fixing soundproof enclosure to compressors and air conditioning products, sound insulation, fixing of the engineering wire 300, shielding and grounding, and support and limiting of the magnetic ring 205 can be achieved simultaneously in the compressor area. This solves the problems of existing compressors and air conditioning products, such as the lack of a dedicated wire-fixing structure for the engineering wire 300 when it passes through the compressor area, poor wiring consistency, unstable fixing of the magnetic ring 205, and insufficient EMC protection.

[0090] In the above embodiments, the specific structure, size, material and arrangement of the soundproof cover 100, electromagnetic compatibility wiring device 200, cable tray shell 201, shield 202, grounding component 203, magnetic ring support layer 204, magnetic ring 205 and magnetic strip 206 can be adapted to the actual compressor model, engineering line 300 specifications and electromagnetic compatibility performance requirements.

[0091] For example, the shielding component 202 can be made of flexible conductive materials such as metal braided mesh, metal foil, or conductive cloth to adapt to deformation during the opening and closing of the wire trough housing 201. The magnetic strip 206 can be made of flexible rubber or sintered magnetic strip, and its magnetic force can be selected according to the closing retention force requirements of the wire trough housing 201. The number of support components in the magnetic ring support layer 204 can be set along the length of the wire trough housing 201, with one or more components to accommodate different numbers of magnetic rings 205.

[0092] Furthermore, the technical features in the above embodiments can be combined with each other without contradicting each other to form more implementation methods. For example, the specific structure of the wire trough housing 201 in Embodiment 2, the connection method of the shield 202 and the grounding component 203 in Embodiment 3, the structure of the magnetic ring support layer 204 in Embodiment 4, and the compressor and air conditioner application scenario in Embodiment 6 can all be freely combined according to actual needs and all fall within the scope of protection claimed by this invention.

[0093] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
