Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to a housing assembly, a compressor, and a refrigeration device. Background Technology

[0002] Currently, in related technologies, terminal covers are installed on compressors to protect the compressor terminals, isolating them from the outside air. This is especially important in special equipment rooms or when the compressor uses flammable refrigerant, preventing deflagration due to short-circuit sparking. When assembling the terminal cover, the seals and the terminal cover must first be fixed to the compressor housing, and then the connectors are inserted through the terminal cover and seals to secure them. However, because the assembly process requires first positioning the terminal cover against the housing and then inserting the connectors, the assembly process is relatively complex and inefficient. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model proposes a shell assembly.

[0005] The second aspect of this utility model provides a compressor.

[0006] The third aspect of this utility model proposes a refrigeration device.

[0007] In view of the above, the first aspect of this utility model provides a housing assembly for a compressor. The housing assembly includes a first housing, a base plate, a second housing, a terminal block, a first seal, a second seal, and a first connector. The base plate is disposed on the first housing and has a first mounting hole. The second housing is disposed on the side of the base plate away from the first housing and has a mounting cavity communicating with the first mounting hole. The terminal block is disposed on the first housing and located within the first mounting hole and the mounting cavity. The first seal is disposed between the base plate and the first housing. The second seal is disposed between the base plate and the second housing. The first connector passes through the second housing, the second seal, the base plate, and the first seal, and is connected to the first housing.

[0008] The housing assembly provided in this application is used in a compressor. The housing assembly includes a first housing, which serves as the compressor's housing. The housing assembly also includes a base plate and a second housing. The first housing, base plate, and second housing enclose a sealed mounting cavity. The housing assembly also includes terminals disposed within the mounting cavity, isolating the terminals from the external environment. This isolation prevents deflagration caused by short-circuit sparking in special equipment rooms or when the compressor uses flammable refrigerant. Isolation of the terminals from the external environment prevents leakage of flammable refrigerant to the outside of the compressor in the event of leakage at the terminals. Isolation also prevents damage to the terminals from external forces. Furthermore, isolation reduces the risk of water and dust intrusion, improving the reliability of the terminals. It also prevents short circuits between terminals or adverse effects on electrical connections caused by water or dust, improving equipment efficiency and service life. Finally, isolation prevents contact accidents, ensuring the safety of operators and users.

[0009] The housing assembly also includes a first seal, disposed between the base plate and the first housing. The first seal seals the space between the base plate and the first housing, reducing the probability of communication between the mounting cavity and the external space of the second housing, thus further improving the sealing effect of the mounting cavity. The housing assembly also includes a second seal, disposed between the base plate and the second housing. The second seal seals the space between the base plate and the second housing, further reducing the probability of communication between the mounting cavity and the external space of the second housing, thus improving the sealing effect of the mounting cavity.

[0010] The shell assembly also includes a first connector, which passes through the second shell, the second seal, the base plate, and the first seal, and is connected to the first shell. This connection not only secures the second shell, the second seal, the base plate, and the first seal, but also strengthens the overall structure of the shell assembly, enhances its sealing performance, and improves the explosion-proof performance of the terminals. During assembly, the first connector positions the first seal, the base plate, the second seal, and the second shell sequentially through the first connector. This eliminates the need for additional positioning processes, simplifying the assembly process, reducing assembly difficulty, and ultimately improving assembly efficiency.

[0011] The base plate is provided with a first mounting hole, and the wiring terminal is located in the first housing and enters the mounting cavity after passing through the first mounting hole, so as to avoid interference between the base plate and the wiring terminal and improve the smoothness of the connection between the wiring terminal and the cable.

[0012] In some technical solutions of this utility model, optionally, at least one of the first sealing member and the second sealing member is bonded to the base plate.

[0013] In this technical solution, at least one of the first and second seals is bonded to the base plate. When the shell assembly is assembled by an automated device, at least two of the bonded second shell, the first seal, and the second seal can be assembled at once. This reduces the number of components required for the shell assembly, simplifies the assembly process when assembling the shell assembly by an automated device, reduces the assembly difficulty of the shell assembly, and thus improves the assembly efficiency of the shell assembly on the automated device, making the assembly of the shell assembly faster and more convenient.

[0014] In some technical solutions of this utility model, optionally, the first connector is welded to the first housing, and the housing assembly further includes a second connector, which is connected to the first connector and pressed onto the side of the second housing away from the first housing.

[0015] In this technical solution, the shell assembly also includes a second connector, which is connected to the first connector and pressed onto the side of the second shell away from the first shell. This secures the second shell, the second seal, the base plate, and the first seal, further improving the stability and sealing of the shell assembly. The first connector is welded to the first shell. During assembly of the shell assembly, the first seal, the base plate, the second seal, and the second shell are sequentially passed through the first connector, and then the second connector is connected to the first connector. This simplifies the assembly process when assembling the shell assembly using automated equipment, reduces the assembly difficulty, and thus improves the assembly efficiency of the shell assembly on automated equipment.

[0016] Optionally, in some technical solutions of this utility model, the second housing includes a first body and a mounting platform, the mounting platform is connected to the first body, the first connector passes through the mounting platform, and the second connector is pressed against the first mounting surface of the mounting platform.

[0017] In this technical solution, the second housing includes a first body and a mounting platform. The second connector is pressed onto the first mounting surface of the mounting platform. The second connector can be more reliably fixed relative to the first mounting surface, further improving the stability of the assembled housing assembly.

[0018] In some technical solutions of this utility model, optionally, the side of the first body away from the first housing has a first surface; the first mounting surface is closer to the first housing than the first surface.

[0019] In this technical solution, the first mounting surface is closer to the first housing than the first surface, so that the distance between the first mounting surface and the first housing is smaller than the distance between the first surface and the first housing. This shortens the length of the first connector. After the first connector is assembled with the first housing, the installation error of the end of the first connector that is far from the first housing is reduced, so that the holes on the first seal, the base plate, the second seal and the housing can be more accurately aligned with the first connector, further reducing the assembly difficulty of the housing assembly.

[0020] In some technical solutions of this utility model, optionally, the height of the first body is greater than or equal to 35 mm and less than or equal to 70 mm; and / or the height of the mounting platform is greater than or equal to 5 mm and less than or equal to the height of the first body.

[0021] In this technical solution, the height of the first body is 35 mm to 70 mm. While ensuring sufficient space in the mounting cavity, this reduces the space occupied by the second housing on the compressor's external space, thereby reducing the overall volume of the compressor. The height of the mounting platform is greater than or equal to 5 mm and less than or equal to the height of the first body. While ensuring sufficient strength of the mounting platform, this shortens the required length of the first connector. After the first connector is assembled with the first housing, the installation error at the end of the first connector furthest from the first housing is reduced. This allows the first seal, the base plate, the second seal, and the holes on the housing to be more accurately aligned with the first connector, further reducing the assembly difficulty of the housing assembly.

[0022] In some technical solutions of this utility model, optionally, the number of first connectors is multiple, and the multiple first connectors are arranged in parallel.

[0023] In this technical solution, there are multiple first connectors arranged in parallel, which makes the pressure from the first connectors on the second housing more evenly distributed, further improving the stability and sealing of the housing assembly. Furthermore, the parallel arrangement of multiple first connectors allows for simultaneous fixation of the second housing at multiple locations, reducing the probability of displacement or rotation of the second housing due to compressor vibration or other reasons, further enhancing the stability of the housing assembly.

[0024] The base plate is provided with a first protrusion, which is arranged circumferentially along the first mounting hole and abuts against the first seal.

[0025] In this technical solution, a first protrusion is provided on the side of the base plate near the first seal, surrounding the first mounting hole. This first protrusion abuts against the first seal, increasing the force between the base plate and the first seal, resulting in a tighter contact and improved sealing performance. Furthermore, by using the first protrusion on the side of the base plate near the first seal to seal against it, the contact area between the base plate and the first seal is reduced, thereby increasing the pressure between them. This results in greater pressure at the contact point, further strengthening the seal and enhancing the overall sealing effect. This makes it easier for the housing assembly to meet the required waterproof and dustproof requirements.

[0026] Optionally, in some technical solutions of this utility model, the first housing is provided with a second mounting surface, and the first sealing member is attached to the second mounting surface.

[0027] In this technical solution, the first housing is provided with a second mounting surface, and the first seal is attached to the second mounting surface. The second mounting surface improves the flatness of the surface of the first housing, thereby improving the installation accuracy of the first seal, so that the first seal, the base plate, the second seal and the housing have better installation accuracy.

[0028] Optionally, in some technical solutions of this utility model, the side wall of the second housing is provided with a wire outlet hole, which communicates with the mounting cavity. The housing assembly also includes a cable and a wire guide sleeve. The cable is connected to the terminal block and extends from the wire outlet hole to the outside of the second housing. The wire guide sleeve is engaged with the wire outlet hole and sleeved on the cable.

[0029] In this technical solution, the housing assembly also includes a cable and a cable guide sleeve. One end of the cable is connected to the terminal block, and the other end extends from the outlet hole to the outside of the second housing, using the cable to provide power to the equipment. The cable guide sleeve is fitted into the outlet hole and over the cable, ensuring the sealing of the outlet and isolating the interior of the housing assembly from the outside air, thus giving the terminal block explosion-proof performance.

[0030] In some technical solutions of this utility model, optionally, the second sealing member includes a second body and a sealing part, the sealing part is disposed on the side of the second body near the second housing, located in the mounting cavity, and arranged along the inner wall of the second housing.

[0031] In this technical solution, the second body achieves sealing by cooperating with the second housing through a sealing part, increasing the contact area between the second seal and the second housing, and further improving the sealing effect between the second seal and the second housing. Furthermore, the sealing part is located within the mounting cavity and arranged along the inner wall of the second housing. During the assembly of the housing assembly, the sealing part can position the second housing, further improving the convenience of the housing assembly process.

[0032] The second aspect of this invention provides a compressor comprising a housing assembly as described in any of the above-described technical solutions. Therefore, this compressor possesses all the beneficial effects of the housing assembly as described in any of the above-described technical solutions.

[0033] A third aspect of this utility model provides a refrigeration device, including a compressor as described in the above-described technical solution. Therefore, this refrigeration device possesses all the beneficial effects of the compressor described in the above-described technical solution.

Detailed Implementation

[0046] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0048] The following reference Figures 1 to 8 This invention describes a housing assembly, a compressor, and a refrigeration device according to some embodiments of the present invention.

[0049] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, a housing assembly 100 is provided for a compressor. The housing assembly 100 includes a first housing 110, a base plate 120, a second housing 130, a terminal block 140, a first seal 150, a second seal 160, and a first connector 172. The base plate 120 is disposed on the first housing 110 and has a first mounting hole 122. The second housing 130 is disposed on the side of the base plate 120 away from the first housing 110 and has a mounting cavity 172. 32. The mounting cavity 132 is connected to the first mounting hole 122; the terminal block 140 is disposed in the first housing 110, located in the first mounting hole 122 and the mounting cavity 132; the first seal 150 is disposed between the base plate 120 and the first housing 110; the second seal 160 is disposed between the base plate 120 and the second housing 130; the first connector 172 passes through the second housing 130, the second seal 160, the base plate 120 and the first seal 150, and is connected to the first housing 110.

[0050] In this embodiment, the housing assembly 100 is used for a compressor. The housing assembly 100 includes a first housing 110, which serves as the compressor housing. The housing assembly 100 also includes a base plate 120 and a second housing 130. The first housing 110, base plate 120, and second housing 130 enclose a sealed mounting cavity 132. The housing assembly 100 also includes a terminal block 140, which is disposed within the mounting cavity 132, isolating the terminal block 140 from the external environment. This isolation prevents deflagration caused by short-circuit sparking in special equipment rooms or when the compressor uses flammable refrigerant. Isolation of the terminal block 140 also prevents leakage of flammable refrigerant to the outside of the compressor in the event of leakage at the terminal block 140. Isolation of the terminal block 140 also prevents damage from external forces. Furthermore, isolation of the terminal block 140 reduces the risk of water and dust intrusion, improving its reliability. To prevent short circuits between terminals 140 due to water or dust, or to avoid adverse effects on electrical connection performance, the equipment's operating efficiency and lifespan are improved. Terminal 140 is isolated from the external environment, preventing contact accidents and ensuring the safety of operators and users.

[0051] The housing assembly 100 also includes a first seal 150, which is disposed between the base plate 120 and the first housing 110. The first seal 150 achieves a seal between the base plate 120 and the first housing 110, reducing the probability of communication between the mounting cavity 132 and the external space of the second housing 130, and further improving the sealing effect of the mounting cavity 132. The housing assembly 100 also includes a second seal 160, which is disposed between the base plate 120 and the second housing 130. The second seal 160 achieves a seal between the base plate 120 and the second housing 130, further reducing the probability of communication between the mounting cavity 132 and the external space of the second housing 130, and improving the sealing effect of the mounting cavity 132.

[0052] The housing assembly 100 also includes a first connector 172, which passes through the second housing 130, the second seal 160, the base plate 120 and the first seal 150, and is connected to the first housing 110. Through the connection between the first connector 172 and the first housing 110, the second housing 130, the second seal 160, the base plate 120 and the first seal 150 are fixed, making the overall structure of the housing assembly 100 more robust, enhancing the sealing effect of the housing assembly 100, and improving the explosion-proof performance of the terminal block 140. The first connector 172 is connected to the first housing 110. When assembling the housing assembly 100, the first seal 150, the base plate 120, the second seal 160, and the second housing 130 are sequentially passed through the first connector 172. The first connector 172 can position the first seal 150, the base plate 120, the second seal 160, and the second housing 130, and realize the assembly of the housing assembly 100. It is no longer necessary to use an additional positioning process to position the first seal 150, the base plate 120, the second seal 160, and the second housing 130, which simplifies the assembly process of the housing assembly 100, reduces the assembly difficulty of the housing assembly 100, and thus improves the assembly efficiency of the housing assembly 100.

[0053] The base plate 120 is provided with a first mounting hole 122. The terminal block 140 is disposed in the first housing 110 and enters the mounting cavity 132 after passing through the first mounting hole 122, so as to avoid interference between the base plate 120 and the terminal block 140 and improve the smoothness of the connection between the terminal block 140 and the cable.

[0054] Specifically, the first housing 110 is the end cover of the compressor, and the second housing 130 is the terminal cover.

[0055] Specifically, the mounting cavity 132 has an opening on the side near the first housing 110, and the second housing 130 covers the outside of the terminal block 140.

[0056] Specifically, the first seal 150, the base plate 120, the second seal 160, and the second housing 130 are all provided with through holes, and the through holes of the first seal 150, the base plate 120, the second seal 160, and the second housing 130 are arranged opposite to each other, and the first connector 172 can pass through the through holes of the first seal 150, the base plate 120, the second seal 160, and the second housing 130.

[0057] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0058] like Figure 1 , Figure 2 and Figure 3As shown, at least one of the first seal 150 and the second seal 160 is bonded to the base plate 120.

[0059] In this embodiment, at least one of the first seal 150 and the second seal 160 is bonded to the base plate 120. When the shell assembly 100 is assembled by an automated device, at least two of the bonded second shell 130, the first seal 150 and the second seal 160 can be assembled at one time. This reduces the number of components required for the shell assembly 100 to be assembled, simplifies the assembly process when assembling the shell assembly 100 by an automated device, reduces the assembly difficulty of the shell assembly 100, and thus improves the assembly efficiency of the shell assembly 100 on the automated device, making the assembly of the shell assembly 100 faster and more convenient.

[0060] Specifically, such as Figure 4 As shown, the base plate 120, the first seal 150, and the second seal 160 are bonded together, that is, the first seal 150 and the second seal 160 are respectively bonded to both sides of the base plate 120, so that the base plate 120, the first seal 150, and the second seal 160 form a component. When the shell component 100 is assembled by an automatic device, the automatic device assembles the component formed by the base plate 120, the first seal 150, and the second seal 160 into the first shell 110, and then assembles the second shell 130 onto the component formed by the base plate 120, the first seal 150, and the second seal 160, thereby completing the assembly of the shell component 100. This eliminates the need to assemble the first seal 150, the base plate 120, and the second seal 160 into the first shell 110 in three separate steps, thereby reducing the assembly steps of the shell component 100, simplifying the assembly process when assembling the shell component 100 by an automatic device, reducing the assembly difficulty of the shell component 100, and thus improving the assembly efficiency of the shell component 100 on the automated device.

[0061] Before assembling the housing assembly 100, the base plate 120, the first seal 150, and the second seal 160 are bonded together, so that the bonding process of the base plate 120, the first seal 150, and the second seal 160 will not affect the assembly time of the housing assembly 100.

[0062] The first seal 150 and the base plate 120 are bonded together. When assembling the shell assembly 100, the assembly formed by the first seal 150 and the base plate 120 is assembled into the first shell 110, and then the second seal 160 and the second shell 130 are assembled to realize the assembly of the shell assembly 100.

[0063] The second seal 160 is bonded to the base plate 120. When assembling the shell assembly 100, the first seal 150 is assembled onto the first shell 110, and then the assembly formed by bonding the second seal 160 to the base plate 120 is assembled onto the first seal 150. Then the second shell 130 is assembled to achieve the assembly of the shell assembly 100.

[0064] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0065] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the first connector 172 is welded to the first housing 110. The housing assembly 100 also includes a second connector 174, which is connected to the first connector 172 and is pressed onto the side of the second housing 130 away from the first housing 110.

[0066] In this embodiment, the shell assembly 100 further includes a second connector 174, which is connected to the first connector 172 and pressed onto the side of the second shell 130 away from the first shell 110. This secures the second shell 130, the second seal 160, the base plate 120, and the first seal 150, further improving the stability and sealing of the shell assembly 100. The first connector 172 is welded to the first shell 110. When assembling the shell assembly 100, the first seal 150, the base plate 120, the second seal 160, and the second shell 130 are sequentially passed through the first connector 172, and then the second connector 174 is connected to the first connector 172. This simplifies the assembly process when assembling the shell assembly 100 using automated equipment, reduces the assembly difficulty of the shell assembly 100, and thus improves the assembly efficiency of the shell assembly 100 on automated equipment.

[0067] Specifically, the first connector 172 is a threaded connector, the second connector 174 is a nut, the first connector 172 is welded to the first housing 110, and the nut is tightened to the end of the first connector 172 away from the first housing 110.

[0068] Threaded fasteners can be bolts, screws, or studs.

[0069] The first connector 172 can also be a rivet, which is welded to the first housing 110 and riveted to the second housing 130.

[0070] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0071] likeFigure 1 and Figure 2 As shown, the second housing 130 includes a first body 134 and a mounting platform 136. The mounting platform 136 is connected to the first body 134. A first connector 172 passes through the mounting platform 136, and a second connector 174 is pressed against the first mounting surface 138 of the mounting platform 136.

[0072] In this embodiment, the second housing 130 includes a first body 134 and a mounting platform 136. The second connector 174 is pressed onto the first mounting surface 138 of the mounting platform 136. The second connector 174 can be more reliably fixed relative to the first mounting surface 138, further improving the stability of the assembled housing assembly 100.

[0073] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0074] like Figure 1 and Figure 2 As shown, the first body 134 has a first surface 135 on the side away from the first housing 110; the first mounting surface 138 is closer to the first housing 110 than the first surface 135.

[0075] In this embodiment, the first mounting surface 138 is closer to the first housing 110 than the first surface 135, so that the distance between the first mounting surface 138 and the first housing 110 is smaller than the distance between the first surface 135 and the first housing 110. This shortens the length of the first connector 172. After the first connector 172 is assembled with the first housing 110, the installation error of the end of the first connector 172 away from the first housing 110 is reduced, so that the first seal 150, the base plate 120, the second seal 160 and the holes on the housing can be more accurately aligned with the first connector 172, further reducing the assembly difficulty of the housing assembly 100.

[0076] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0077] like Figure 1 , Figure 2 and Figure 6 As shown, the height b of the first body 134 is greater than or equal to 35 mm and less than or equal to 70 mm; and / or the height a of the mounting platform 136 is greater than or equal to 5 mm and less than or equal to the height b of the first body 134.

[0078] In this embodiment, the height b of the first body 134 is 35 mm to 70 mm. While ensuring sufficient space in the mounting cavity 132, it reduces the space occupied by the second housing 130 on the compressor's external space, thereby reducing the overall volume of the compressor. The height a of the mounting platform 136 is greater than or equal to 5 mm and less than or equal to the height b of the first body 134. While ensuring that the mounting platform 136 has a certain strength, it shortens the required length of the first connector 172. After the first connector 172 is assembled with the first housing 110, it reduces the installation error of the end of the first connector 172 away from the first housing 110, so that the first seal 150, the base plate 120, the second seal 160, and the holes on the housing can be more accurately aligned with the first connector 172, further reducing the assembly difficulty of the housing assembly 100.

[0079] Specifically, the height b of the first body 134 can be 35 millimeters.

[0080] The height b of the first body 134 can be 40 mm, 45 mm, 50 mm, 55 mm, 60 mm or 65 mm.

[0081] The height b of the first body 134 can be 70 mm.

[0082] Specifically, the height a of the mounting platform 136 can be 5 millimeters.

[0083] The height a of the mounting platform 136 can be 10 mm, 15 mm, 20 mm or 25 mm.

[0084] Specifically, the height a of the mounting platform 136 can also be equal to the height b of the first body 134.

[0085] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0086] like Figure 1 and Figure 2 As shown, there are multiple first connectors 172, which are arranged side by side.

[0087] In this embodiment, there are multiple first connectors 172 arranged side by side, which makes the pressure exerted on the second housing 130 by the first connectors 172 more evenly distributed on the second housing 130, further improving the stability and sealing of the housing assembly 100. Furthermore, the parallel arrangement of multiple first connectors 172 allows for simultaneous fixation of the second housing 130 at multiple locations, reducing the probability of displacement or rotation of the second housing 130 due to compressor vibration or other reasons, further improving the stability of the housing assembly 100.

[0088] Specifically, there may be two first connectors 172, which are symmetrically arranged on the second housing 130.

[0089] The number of first connectors 172 can be three, arranged in an equilateral triangle on the second housing 130.

[0090] The number of first connectors 172 can be four, arranged at the four corners of the second housing 130.

[0091] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0092] like Figure 1 , Figure 2 and Figure 7 As shown, the base plate 120 is provided with a first protrusion 124, the first protrusion 124 being circumferentially aligned with the first mounting hole 122. Figure 7 Arranged in the direction indicated by the middle arrow c, and abutting against the first seal 150.

[0093] In this embodiment, a first protrusion 124 is provided on the side of the base plate 120 near the first seal 150, surrounding the first mounting hole 122. The first protrusion 124 abuts against the first seal 150, resulting in a greater force between the base plate 120 and the first seal 150, and a tighter contact between them, thus improving the sealing effect. Furthermore, by sealing the base plate 120 with the first seal 150 via the first protrusion 124 on the side of the base plate 120 near the first seal 150, the contact area between the base plate 120 and the first seal 150 is reduced, thereby increasing the pressure between them. The contact area between the base plate 120 and the first seal 150 has greater pressure, resulting in a tighter contact between the first seal 150 and the base plate 120, further improving the sealing effect and making it easier for the housing assembly 100 to meet the required waterproof and dustproof requirements.

[0094] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0095] like Figure 1 , Figure 2 and Figure 5 As shown, the first housing 110 is provided with a second mounting surface 112, and the first seal 150 is attached to the second mounting surface 112.

[0096] In this embodiment, the first housing 110 is provided with a second mounting surface 112, and the first seal 150 is attached to the second mounting surface 112. The second mounting surface 112 improves the flatness of the surface of the first housing 110, thereby improving the installation accuracy of the first seal 150, so that the first seal 150, the base plate 120, the second seal 160 and the housing have better installation accuracy.

[0097] Furthermore, the second mounting surface 112 is a plane.

[0098] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0099] like Figure 1 , Figure 2 and Figure 8 As shown, the side wall of the second housing 130 is provided with a cable outlet hole 139, which communicates with the mounting cavity 132. The housing assembly 100 also includes a cable 180 and a cable guide sleeve 190. The cable 180 is connected to the terminal block 140 and extends from the cable outlet hole 139 to the outside of the second housing 130. The cable guide sleeve 190 is engaged with the cable outlet hole 139 and sleeved on the cable 180.

[0100] In this embodiment, the housing assembly 100 further includes a cable 180 and a cable sheath 190. One end of the cable 180 is connected to the terminal block 140, and the other end of the cable 180 extends from the outlet hole 139 to the outside of the second housing 130, providing power to the device via the cable. The cable sheath 190 of the housing assembly 100 is engaged with the outlet hole 139 and sleeved over the cable 180, thereby achieving a seal at the outlet and ensuring that the interior of the housing assembly 100 is isolated from the outside air, thus giving the terminal block 140 explosion-proof performance.

[0101] Specifically, the cable guide sleeve 190 can be a grid head, which utilizes the waterproof and flame-retardant properties of the grid head to improve the sealing performance of the housing assembly 100.

[0102] This embodiment provides a shell assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0103] like Figure 1 , Figure 2 and Figure 4 As shown, the second seal 160 includes a second body 162 and a sealing part 164. The sealing part 164 is disposed on the side of the second body 162 near the second housing 130, located in the mounting cavity 132, and arranged along the inner wall of the second housing 130.

[0104] In this embodiment, the second body 162 achieves sealing by cooperating with the second housing 130 through the sealing part 164, which increases the contact area between the second sealing element 160 and the second housing 130, further improving the sealing effect between the second sealing element 160 and the second housing 130. Furthermore, the sealing part 164 is located within the mounting cavity 132 and arranged along the inner wall of the second housing 130. During the assembly of the housing assembly 100, the sealing part 164 can position the second housing 130, further improving the convenience of the assembly process of the housing assembly 100.
