[0063] A compressor 100 according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 14 .
[0064] 1 to 14 , the compressor 100 includes a housing 10, a terminal cover 20, and a terminal 61. The housing 10 has a terminal mounting hole 11 at one end. The terminal cover 20 is mounted on the housing 10, and a mounting space 21 is formed between the terminal cover 20 and the housing 10. For example, a receiving cavity is formed in the terminal cover 20. When the terminal cover 20 is mounted on the housing 10, the receiving cavity is configured as the mounting space 21.
[0065] A portion of the terminal 61 extends into the housing 10, and another portion of the terminal 61 extends into the installation space 21, that is, the terminal 61 is inserted into the terminal installation hole 11. The housing 10 and the terminal cover 20 work together to seal the terminal 61 within the housing 10 and the installation space 21. The housing 10 and the terminal cover 20 can be used to protect the terminal 61 and prevent the terminal 61 from being damaged by the external environment.
[0066] Compressor 100 also includes a connecting wire assembly 40, which is used to electrically connect terminals 61 to an external circuit. In related art, a wire outlet is provided at the junction of housing 10 and terminal cover 20, through which connecting wire assembly 40 can extend outside installation space 21. Refrigerant used by compressor 100 or debris from the external environment, such as water, water vapor, and oxygen, can easily enter installation space 21 through the outlet, making contact with terminals 61 and causing a series of failures in compressor 100, including short circuits, corrosion, poor contact, and sparks.
[0067] In the present application, a seal 30 is provided between the housing 10 and the terminal cover 20. The seal 30 can seal the gap between the housing 10 and the terminal cover 20, and can prevent refrigerant or debris in the external environment such as water, water vapor, oxygen, etc. from entering the installation space 21. A wire passage 31 is provided on the seal 30, and the wire passage 31 is connected to the installation space 21. The connecting wire group 40 is passed through the wire passage 31 for electrically connecting the terminal to the external circuit. At the same time, the seal 30 is fixed between the housing 10 and the terminal cover 20, which can fix the position of the seal 30 and prevent the seal 30 from shifting, causing problems such as poor sealing.
[0068] The seal 30 can not only seal the gap between the shell 10 and the terminal cover 20, but also seal the connecting wire group 40, which can prevent the refrigerant or water, water vapor, oxygen and other debris in the external environment from entering the installation space 21 through the gap between the shell 10 and the terminal cover 20 or the gap between the seal 30 and the connecting wire group 40, and avoid the refrigerant or water, water vapor, oxygen and other debris in the external environment from contacting the terminal 61, which can reduce the probability of a series of faults such as short circuit, corrosion, poor contact or sparks in the compressor 100.
[0069] For example, compressor 100 uses flammable and explosive refrigerants such as R290. It is necessary to minimize ignition sources within compressor 100 to reduce sparks from terminals 61 during electrical connections. Sealing member 30 can seal the gap between connecting wire assembly 40 and terminal cover 20 and housing 10, thereby sealing terminal 61 within installation space 21. Sealing member 30 can prevent flammable and explosive refrigerants from coming into contact with terminal 61, thereby preventing sparks from terminal 61 during electrical connections, further improving the safety and reliability of compressor 100 during operation.
[0070] According to the compressor 100 of the embodiment of the present application, a seal 30 is arranged between the shell 10 and the terminal cover 20, and a wire passage 31 is provided in the seal 30. The connecting wire group 40 is passed through the wire passage 31. The seal 30 is used to seal the gap between the connecting wire group 40 and the terminal cover 20 and the shell 10 to prevent the refrigerant or water, water vapor, oxygen and other debris in the external environment from entering the installation space 21. It can prevent the refrigerant or water, water vapor, oxygen and other debris in the external environment from contacting the terminal 61, and can reduce the probability of a series of faults such as short circuit, corrosion, poor contact or sparking in the compressor 100, thereby improving the safety and reliability of the compressor 100 during operation.
[0071] According to some embodiments of the present application, referring to Figures 1 to 5, the compressor 100 further includes at least one fixing member 50. The compressor 100 may further include one fixing member 50. One fixing member 50 may save installation space and facilitate the installation of other parts of the compressor 100. The compressor 100 may further include multiple fixing members 50. The multiple fixing members 50 may be spaced apart on the housing 10 and the terminal cover 30, and may provide fastening force to different parts of the housing 10 and the terminal cover 20, so that the fastening force between the housing 10 and the terminal cover 20 is more balanced.
[0072] The fixing member 50 is used to fix the shell 10 and the terminal cover 20 together, so that the shell 10 and the terminal cover 20 are squeezed in a direction close to each other, so that the terminal cover 20 can be fixed to the shell 10. Using at least one fixing member 50 to fix the terminal cover 20 and the shell 10 can ensure the stability and firmness of the terminal cover 20 fixed to the shell 10.
[0073] The seal 30 is located between the shell 10 and the terminal cover 20. While the fixing member 50 is used to fix the shell 10 and the terminal cover 20, the seal 30 can be squeezed so that the gap between the shell 10 and the seal 30 and the gap between the seal 30 and the terminal cover 20 are further reduced, and the gap between the seal 30 and the connecting wire group 40 can also be reduced at the same time, so that the seal 30 is better sealed between the shell 10, the terminal cover 20 and the connecting wire group 40, so as to improve the sealing performance of the seal 30.
[0074] For example, the fixing member 50 may include a bolt 51 and a nut 52 , or a rivet, etc.
[0075] According to some embodiments of the present application, referring to Figures 1 to 5, the fixing member 50 includes a bolt 51 and a nut 52. The bolt 51 is fixed to the housing 10. For example, the bolt 51 can be integrally formed with the housing 10. A bolt matching hole is formed on the terminal cover 20. The bolt 51 is passed through the bolt matching hole and extends from the installation space 21. The nut 52 is used to tighten with the bolt 51 to fix the terminal cover 20 to the housing 10, which can ensure that the terminal cover 20 is firmly fixed to the housing 10.
[0076] The combination of the nut 52 and the bolt 51 can, on the one hand, make the method of fixing the connection between the shell 10 and the terminal cover 20 simple and easy to operate; on the other hand, by loosening the bolt 51, the terminal cover 20 can be removed from the shell 10, which is convenient for repairing the internal structure of the compressor 100; at the same time, the seal 30 can also be removed, which is convenient for replacing the seal 30.
[0077] According to some embodiments of the present application, referring to Figures 6-7 and 9, a fixing member mating hole 32 and a terminal assembly hole 33 are formed on the sealing member 30, and the fixing member mating hole 32 and the terminal assembly hole 33 are spaced apart. A bolt 51 is inserted through the fixing member mating hole 32, and a terminal 61 is inserted through the terminal assembly hole 33 to limit the position of the sealing member 30, thereby better positioning the sealing member 30 and preventing the sealing member 30 from moving.
[0078] Specifically, the bolts 51 on the housing 10 are passed through the fixing member fitting holes 32 and the bolt fitting holes to fix the sealing member 30 and the terminal cover 20 to the housing 10 .
[0079] According to some embodiments of the present application, referring to Figures 4-11 , the wire passage 31 includes a wire hole 341 having an opening. Specifically, when the seal 30 is installed between the housing 10 and the terminal cover 20 , the opening of the wire hole 341 faces the terminal cover 20 . The connecting wire assembly 40 includes a connecting wire 41 . Specifically, there may be multiple connecting wires 41 , for example, three connecting wires 41 , namely, three phase wires R, S, and T. The connecting wire 41 can be installed into the wire passing hole groove 341 through the opening of the wire passing hole groove 341. Specifically, the wire passing channel 31 may include multiple wire passing hole grooves 341. Correspondingly, the number of wire passing hole grooves 341 can be three, and the R, S, and T three-phase wires can be installed into the corresponding wire passing hole grooves 341 through the opening; the wire passing channel 31 may also include a wire passing hole groove 341, and multiple connecting wires 41 can be fixed together with structural adhesive and passed through a wire passing hole groove 341. The structural adhesive can seal the gaps between the multiple connecting wires 41.
[0080] The groove depth H of the wire-passing hole groove 341 and the diameter D of the connecting line 41 satisfy: H≥1.5D. The cross-section of the connecting line 41 is circular. Correspondingly, the groove bottom of the wire-passing hole groove 341 is also an arc transition. The groove depth H of the wire-passing hole groove 341 refers to the straight-line distance from the plane where the opening of the wire-passing hole groove 341 is located to the deepest part of the groove bottom of the wire-passing hole groove 341.
[0081] The groove depth H of the wire passing groove 341 and the diameter D of the connecting wire 41 satisfy: H≥1.5D. After the connecting wire 41 is installed in the wire passing groove 341, the connecting wire 41 needs to be fixed. When H=1.0D, the connecting wire 41 is installed in the wire passing groove 341, and the connecting wire 41 is flush with the plane where the opening of the wire passing groove 341 is located, which is not conducive to the fixation of the connecting wire 41; when 1.5D>H≥1.0D, the connecting wire 41 can be completely accommodated in the wire passing groove 341, but the connecting wire 41 needs to be sealed, which is not conducive to the sealing of the connecting wire 41. When H≥1.5D, the connecting wire 41 can not only be completely accommodated in the wire passing groove 341, but the wire passing groove 341 can reserve enough space to seal the connecting wire 41, but also facilitate the installation and fixation of the connecting wire 41, so that the connecting wire 41 is not easy to move. For example, the relationship between the depth H of the wire hole 341 and the diameter D of the connecting wire 41 may include H=1.5D, H=1.6D, H=1.7D, H=1.8D, H=1.9D, H=2.0D, etc.
[0082] According to some embodiments of the present application, referring to Figures 6 to 11, the seal 30 includes a seal body 34 and a wire hole rib 35. The wire hole rib 35 can be connected to the seal body 34, or the seal body 34 and the wire hole rib 35 can be of separate designs. A wire hole groove 341 opening toward one side is formed on the seal body 34. Specifically, when the seal 30 is installed on the housing 10, the opening of the wire hole groove 341 can face away from the housing 10. The head of the wire hole rib 35 fits in the opening of the wire hole groove 341 to cooperate with the wire hole groove 341 to construct a wire channel 31. The connecting wire group 40 passes through the wire channel 31, and the wire hole rib 35 can fix the connecting wire group 40 in the wire channel 31.
[0083] For example, the head of the wire hole rib 35 can be interference fit in the end of the wire hole groove 341 facing away from the shell 10, and the wire hole rib 35 can be tied to the sealing body 34 with a cable tie, so that the wire hole rib 35 can be fixed to the sealing body 34 to prevent the wire hole rib 35 from falling off the wire hole groove 341.
[0084] For another example, the bottom surface of the head of the wire hole rib 35 can be arc-shaped, and the cross-section of the connecting wire 41 can be circular, so that the head of the wire hole rib 35 can completely match the connecting wire 41, so that the wire hole rib 35 can tightly seal the connecting wire 41 and prevent a gap from forming between the wire hole rib 35 and the connecting wire 41. The diameter of the head of the wire hole rib 35 is larger than the diameter of the wire hole groove 341, so that the head of the wire hole rib 35 and the wire hole groove 341 can have an interference fit, thereby allowing the connecting wire assembly 40 to be fixed in the wire passage 31.
[0085] For another example, the number of the wire hole slots 341 is equal to the number of the heads of the wire hole pressing ribs 35 and corresponds one to one, so that the heads of the wire hole pressing ribs 35 can be pressed into the wire hole slots 341 .
[0086] According to some embodiments of the present application, with reference to Figures 5 to 8, a first fixing structure 341 is formed at a position of the sealing body 34 near the wire hole groove 341, and a second fixing structure 351 is formed on the wire hole rib 35. When the head of the wire hole rib 35 is fitted into the opening of the wire hole groove 341, the first fixing structure 342 can cooperate with the second fixing structure 351 to fix the wire hole rib 35 to the sealing body 34. The wire hole rib 35 can be further fixed to the sealing body 34, which can improve the sealing performance of the wire hole rib 35 in sealing the connecting wire group 40, and prevent the wire hole rib 35 from shaking in the wire hole groove 341 under the action of external force, resulting in problems such as poor sealing of the wire hole rib 35.
[0087] The head of the wire hole pressure rib 35 is fixed in the wire hole groove 341. The first fixing structure 342 is matched with the second fixing structure 351 to fix the wire hole pressure rib 35. The first fixing structure 342 is set at a position close to the wire hole groove 341 to increase the force of the wire hole pressure rib 35 pressing the wire hole groove 341, so as to increase the firmness of the head of the wire hole pressure rib 35 fixed to the wire hole groove 341.
[0088] For example, the first fixing structure 342 may include a groove 3421, a buckle, or a cable tie, and the second fixing structure 351 may include a boss 3511, a clip, or a cable tie. When the head of the cable hole pressure rib 35 is pressed into the cable hole groove 341, the boss 3511 may be located in the groove 3421, and the buckle and the clip may cooperate, or a cable tie may be used to tie the cable hole pressure rib 35 to the seal body 34. All of the above methods can improve the firmness of the cable hole pressure rib 34 fixed to the seal body 34.
[0089] According to some embodiments of the present application, referring to Figures 5 to 8, the first fixing structure 342 is one of a groove 3421 or a boss 3511, and the second fixing structure 351 is the other of the groove 3421 or the boss 3511. The first fixing structure 342 is the groove 3421, which can be located adjacent to the wire hole groove 341; the second fixing structure is the boss 3511, which is formed on the wire hole rib 35; or, the first fixing structure 342 is the boss 3511, which can be located adjacent to the wire hole groove 341, and the second fixing structure 351 is the groove 3421, which is formed on the wire hole rib 35.
[0090] The fitting mode between the groove 3421 and the boss 3511 is an interference fit. When the head of the wire hole rib 35 is fixed to the wire hole groove 341, the wire hole rib 35 can synchronously drive the groove 3421 or the boss 3511 to cooperate with the boss 3511 or the groove 3421 on the seal body 34, which can further increase the firmness of the wire hole rib 35 fixed to the seal body 34.
[0091] The first fixing structure 342 is one of the groove 3421 and the boss 3511. The groove 3421 and the boss 3511 can be formed together with the seal body 34, eliminating the need for mounting the groove 3421 and the boss 3511 on the seal body 34 and further increasing the secure connection between the groove 3421 and the boss 3511 and the seal body 34. The second fixing structure 351 is the other of the groove 3421 and the boss 3511. The groove 3421 and the boss 3511 can be formed together with the wire hole rib 35, eliminating the need for mounting the groove 3421 and the boss 3511 on the wire hole rib 35 and further increasing the secure connection between the groove 3421 and the boss 3511 and the wire hole rib 35.
[0092] When the head of the wire hole rib 35 is fixed into the wire hole groove 341, the wire hole rib 35 can synchronously drive the groove 3421 or the boss 3511 to cooperate with the boss 3511 or the groove 3421 on the seal body 34. No additional fixation is required, and no additional process is generated, which can increase assembly efficiency.
[0093] For example, the first fixing structure 342 is a groove 3421, and the second fixing structure 351 is a boss 3511. The direction of the opening of the groove 342 is the same as the direction of the opening of the wire hole groove 341, and the groove depth of the groove 3421 is greater than the groove depth of the wire hole groove 341; the extension direction of the boss 3511 is the same as the extension direction of the head of the wire hole rib 35, and the extension height of the boss 3511 is greater than the extension height of the head of the wire hole rib 35, which can better fix the wire hole rib 35 to the seal body 34.
[0094] According to some embodiments of the present application, referring to Figures 6 to 12, the seal 30 further includes a connecting rib 36, which is connected between the wire hole pressure rib 35 and the seal body 34. That is, the wire hole pressure rib 35 can be connected to the seal body 34. The seal 30 is designed as an integral part, so that the wire hole pressure rib 35 is not easily lost.
[0095] When the wire hole pressing rib 35 is needed to press the connecting wire group 40, the wire hole pressing rib 35 can be flipped over, and the wire hole pressing rib 35 drives the connecting rib 36 to fold from near the middle of the connecting rib 36, so that the wire hole pressing rib 35 can be flipped over to the top of the wire hole groove 341, and the head of the wire hole pressing rib 35 can continue to be pressed into the wire hole groove 341.
[0096] When using the connecting rib 36 to press the connecting wire assembly 40 through the wire hole pressing rib 35, it is necessary to fold the wire hole pressing rib 35. The thickness T of the connecting rib 36 and the length L of the connecting rib 36 satisfy the following relationship: T < L / 2. If the thickness of the connecting rib 36 is less than half the length of the connecting rib 36, the connecting rib 36 can be folded with less force, making it easier to fold the connecting rib 36. For example, the relationship between the thickness T of the connecting rib 36 and the length L of the connecting rib 36 can be: T = L / 3, T = L / 4, T = L / 5, etc.
[0097] If the thickness of the connecting rib 36 is greater than or equal to half the length of the connecting rib 36, after folding from near the middle of the connecting rib 36, the connecting rib 36 is easy to reset, and the force that needs to be overcome to fix the wire hole pressure rib 35 to the wire hole groove 341 is large, which is not conducive to the fixation of the wire hole pressure rib 35.
[0098] Preferably, the connecting rib 36 can be a thin and long component, which makes it easier to fold the connecting rib 36, and after folding, the connecting rib 36 is not easy to reset, thereby improving the stability of the head of the wire hole pressure rib 35 fixed to the wire hole groove 341.
[0099] According to some embodiments of the present application, referring to Figures 6 to 12, the connecting wire assembly 40 is interference-fitted in the wire passage 31, preventing the connecting wire assembly 40 from falling out of the wire passage 31. Alternatively, at least one rib 311 is formed in the wire passage 31, or a single rib 311 or a plurality of ribs 311 arranged at intervals are formed in the wire passage 31, so that the connecting wire assembly 40 is interference-fitted in the wire passage 31.
[0100] At least one rib 311 is formed in the wire channel 31 to match the connecting wire groups 40 of different diameters. The rib 311 can increase the sealing of the connecting wire groups 40 without causing excessive compression force, so as to fix the connecting wire groups 40 of different diameters into the wire channel 31.
[0101] In some examples, the head of the wire hole rib 35 fits into the opening of the wire hole slot 341 to form a wire passage 40 in cooperation with the wire hole slot 341. At least one rib 311 is formed in the wire passage 31, and the rib 311 can be annular and surrounds the outer circumference of the connecting wire.
[0102] The convex rib 311 may include a first rib and a second rib, the first rib may be arranged at the bottom of the wire-passing hole groove 341, the extension direction of the first rib may be parallel to the end face of the wire-passing hole groove 341, and the end of the first rib away from the bottom of the wire-passing hole groove 341 may be set as an arc transition; the second rib may be arranged at the head of the wire-passing hole pressure rib 35, the extension direction of the second rib may be parallel to the end face of the wire-passing hole pressure rib 35, and the end of the second rib away from the head of the wire-passing hole pressure rib 35 may be set as an arc transition. When the connecting line 41 is installed in the wire-passing hole groove 341, the first rib and the second rib may be pressed against the outer peripheral side of the connecting line 41, which can prevent the first rib and the second rib from crushing the connecting line.
[0103] When the head of the wire hole pressing rib 35 is pressed tightly into the wire hole groove 341 , the end of the first rib and the end of the second rib may abut against each other to form a convex rib 311 .
[0104] The number of first ribs and the number of second ribs are equal and correspond one to one. There can be one or more first ribs, and multiple first ribs can be arranged at intervals at the bottom of the wire hole groove 341; there can be one or more second ribs, and multiple second ribs can be arranged at intervals at the head of the wire hole rib.
[0105] In other examples, at least one rib 311 is formed in the wire-passing channel 31, and the rib 311 may include a plurality of protrusions arranged at intervals in the wire-passing channel 31. The rib 311 may include a plurality of first protrusions and a plurality of second protrusions. The plurality of first protrusions may be arranged at intervals at the bottom of the wire-passing hole groove 341, and the heads of the first protrusions may be arranged to form a circular arc transition; the plurality of second protrusions may be arranged at intervals at the heads of the wire-passing hole pressure rib 35, and the heads of the second protrusions may be arranged to form a circular arc transition. When the connecting wire 41 is installed in the wire-passing hole groove 341, the first protrusion and the second protrusion may be located on the outer circumference of the connecting wire 41, thereby preventing the first protrusion and the second protrusion from crushing the connecting wire.
[0106] According to some embodiments of the present application, referring to Figure 5, the wire inlet of the wire passage 31 faces the wiring terminal of the terminal, so that the connecting wire group 40 between the wiring terminal of the terminal 61 and the wire inlet is parallel to the bottom wall of the terminal cover 20, and the bottom wall of the terminal cover 20 extends in a horizontal direction. The connecting wire group 40 between the wiring terminal of the terminal 61 and the wire inlet is parallel to the bottom wall of the terminal cover 20, that is, the connecting wire group 40 extends in a horizontal direction, which can facilitate the installation of the connecting wire group 40 on the terminal 61.
[0107] For example, when the seal 30 is installed on the housing 10, one end of the connecting wire group 40 is installed on the wiring terminal of the terminal 61, and the other end extends from the wire channel 31. The wire outlet portion of the terminal 61 is flush with the bottom of the wire hole groove 341, so that the connecting wire group 40 can extend in a straight line, which can facilitate the installation of the connecting wire group 40 on the terminal 61.
[0108] According to some embodiments of the present application, referring to Figures 4 to 6 and 14, a second limiting groove 352 is formed on the sealing member 30, and part of the side wall of the terminal cover 20 is inserted into the second limiting groove 352. The second limiting groove 352 can extend in a direction perpendicular to the wire passage 31, and the second limiting groove 352 can be used to limit the position of the terminal cover 20.
[0109] For example, the second limiting groove 352 can be formed on the side of the wire hole pressure rib 35 that is away from the head of the wire hole pressure rib 35. When the wire hole pressure rib 35 is flipped over to press the head of the wire hole pressure rib 35 into the wire hole groove 341, part of the side wall of the terminal cover 20 can be inserted into the second limiting groove 352.
[0110] According to some embodiments of the present application, the connecting wire group 40 includes multiple connecting wires 41, at least some of which are passed through a wire-passing channel 31, wherein at least some of the connecting wires 41 are connected as a whole by structural adhesive. It can be that some of the connecting wires 41 are connected as a whole by structural adhesive, or it can be that all of the connecting wires 41 are connected as a whole by structural adhesive. The structural adhesive can fill the gaps between the multiple connecting wires 41, or the multiple connecting wires 41 can be injection-molded as a whole, so that the multiple connecting wires 41 can be better passed through the wire-passing channel 31. Providing a wire-passing channel 31 on the sealing member 30 can simplify the processing technology of the sealing member 30.
[0111] According to some embodiments of the present application, referring to FIG13 , the wire passage 31 includes a wire hole 312 and a wire slit 313. The connecting wire assembly 40 is adapted to be pressed into the wire hole 312 through the wire slit 313 to secure the connecting wire assembly 40 to the wire hole 312. A guide slope 314 is provided at the wire entry of the wire slit 313 to facilitate guiding the connecting wire assembly 40 from the wire slit 313 into the wire hole 312.
[0112] For example, the sealing member 30 may be an elastic member, and the sealing member 30 has a certain elastic shrinkage, so that the connecting wire assembly 40 can be pressed into the wire passing hole 312 through the wire passing slit 313 .
[0113] The HVAC equipment according to the second embodiment of the present application includes the compressor according to the above-mentioned first embodiment of the present application.
[0114] For example, HVAC equipment may include air conditioners, heat pumps, multi-split units, water heaters and other cooling, heating or heating equipment.
[0115] According to the HVAC equipment of the embodiment of the present application, by setting the above-mentioned compressor 100, it is possible to prevent the refrigerant or water, water vapor, oxygen and other debris in the external environment from entering the installation space 21, and avoid the refrigerant or water, water vapor, oxygen and other debris in the external environment from contacting the terminal 61. The probability of a series of faults such as short circuit, corrosion, poor contact or sparking in the compressor 100 can be reduced, thereby improving the safety and reliability of the compressor 100 during operation, and thereby improving the safety and reliability of the HVAC equipment during operation.
[0116] The following describes a compressor 100 according to an embodiment of the present application with reference to FIG1 , FIG3 , and FIG15 - FIG20 .
[0117] 1 , 3 , and 15 to 20 , the compressor 100 includes a housing 10, a terminal cover 20, and a terminal 61. The housing 10 has a terminal mounting hole 11 at one end. The terminal cover 20 is mounted on the housing 10, and a mounting space 21 is formed between the terminal cover 20 and the housing 10. The terminal cover 20 has a terminal outlet 23. For example, a receiving cavity is formed in the terminal cover 20. When the terminal cover 20 is mounted on the housing 10, the receiving cavity is configured as the mounting space 21.
[0118] A portion of the terminal 61 extends into the housing 10, and another portion of the terminal 61 extends into the installation space 21, that is, the terminal 61 is inserted into the terminal installation hole 11. The housing 10 and the terminal cover 20 work together to seal the terminal 61 within the housing 10 and the installation space 21. The housing 10 and the terminal cover 20 can be used to protect the terminal 61 and prevent the terminal 61 from being damaged by the external environment.
[0119] Compressor 100 also includes a connecting wire assembly 40, which is used to electrically connect terminals 61 to an external circuit. In related art, a wire outlet is provided at the junction of housing 10 and terminal cover 20, through which connecting wire assembly 40 can extend outside installation space 21. Refrigerant used by compressor 100 or debris from the external environment, such as water, water vapor, and oxygen, can easily enter installation space 21 through the outlet, making contact with terminals 61 and causing a series of failures in compressor 100, including short circuits, corrosion, poor contact, and sparks.
[0120] In the present application, a seal 30 is provided between the housing 10 and the terminal cover 20. The seal 30 is used to seal the assembly gap between the terminal outlet 23 and the connecting wire group 40, which can prevent refrigerant or debris in the external environment such as water, water vapor, oxygen, etc. from entering the installation space 21. A wire passage 31 is provided on the seal 30, and the wire passage 31 is connected to the installation space 21. The connecting wire group 40 is passed through the wire passage 31 and is used to electrically connect the terminal to the external circuit. At the same time, the seal 30 is fixed between the housing 10 and the terminal cover 20, which can fix the position of the seal 30 and prevent the seal 30 from shifting, causing problems such as poor sealing.
[0121] The seal 30 can not only seal the gap between the shell 10 and the terminal cover 20, but also seal the connecting wire group 40, which can prevent the refrigerant or water, water vapor, oxygen and other debris in the external environment from entering the installation space 21 through the gap between the shell 10 and the terminal cover 20 or the gap between the seal 30 and the connecting wire group 40, and avoid the refrigerant or water, water vapor, oxygen and other debris in the external environment from contacting the terminal 61, which can reduce the probability of a series of faults such as short circuit, corrosion, poor contact or sparks in the compressor 100.
[0122] The seal 30 is provided with a first limiting portion 37, and the housing 10 and / or the terminal cover 20 are provided with a second limiting portion 22. The second limiting portion 22 may be provided on the housing 10, the terminal cover 20, or both the housing 10 and the terminal cover 20. The first limiting portion 37 cooperates with the second limiting portion 22 to limit the position of the seal 30, thereby further limiting the position of the seal 30 and preventing the seal 30 from moving, thereby improving the sealing performance of the seal 30.
[0123] In some examples, the first limiting portion 37 may include a through hole, which is provided on the seal 30, and the second limiting portion 22 may include a fastener, which may be provided in the housing 10 and / or the terminal cover 20, and the fastener may be passed through the through hole to fix the seal 30 to the housing 10 or the terminal cover 20.
[0124] In other examples, the first limiting portion 37 may include a first limiting groove 371, and the opening of the first limiting groove 371 may face the housing 10 or the terminal cover 20. When the opening of the first limiting groove 371 faces the housing 10, the side wall of the housing 10 may be located within the first limiting groove 371; when the opening of the first limiting groove 371 faces the terminal cover 20, the side wall of the terminal cover 20 may be located within the first limiting groove 371. Then, by fixing the housing 10 and the terminal cover 20, the housing 10 and the terminal cover 20 can compress the sealing member 30. With the above installation methods, the position of the sealing member 30 can be limited.
[0125] For example, the compressor 100 uses flammable and explosive refrigerants such as R290. It is necessary to minimize the ignition source within the range of the compressor 100 and reduce the ignition of the terminal 61 during electrical connection. The seal 30 can be used to seal the gap between the connecting wire group 40 and the terminal cover 20 and the shell 10, and the terminal 61 can be sealed in the installation space 21. The seal 30 can block the flammable and explosive refrigerant from contacting the terminal 61 to avoid the ignition of the terminal 61 during electrical connection, thereby further improving the safety and reliability of the compressor 100 during operation.
[0126] According to the compressor 100 of the embodiment of the present application, a seal 30 is arranged between the shell 10 and the terminal cover 20, and a first limiting portion 37 and a second limiting portion 22 are used to limit the position of the seal 30, so that the seal can better seal the assembly gap between the terminal outlet 23 and the connecting wire group 40, prevent the refrigerant or water, water vapor, oxygen and other debris in the external environment from entering the installation space 21, and prevent the refrigerant or water, water vapor, oxygen and other debris in the external environment from contacting the terminal 61, which can reduce the probability of a series of faults such as short circuit, corrosion, poor contact or sparking in the compressor 100, and improve the safety and reliability of the compressor 100 during operation.
[0127] According to some embodiments of the present application, referring to Figures 16 to 20, the first limiting portion 37 includes a first limiting groove 371, which is provided on the surface of the sealing member 30, and the opening of the first limiting groove 371 faces the terminal cover 20. The second limiting portion 22 includes a side wall of the terminal cover 20, which is inserted into the first limiting groove 371 to limit the position of the sealing member 30. Specifically, the first limiting groove 371 can be located at a position of the sealing member 30 close to the terminal outlet 23. By inserting the side wall of the terminal cover 20 into the first limiting groove 371 to limit the position of the sealing member 30, the sealing member 30 can be pressed against the terminal outlet 23 at the same time.
[0128] Providing the first limiting groove 371 on the sealing member 30 can simplify the arrangement of the first limiting portion 37 on the sealing member and facilitate the insertion of the side wall into the first limiting groove 371 .
[0129] According to some embodiments of the present application, referring to Figures 1 to 16, the compressor 100 further includes at least one fixing member 50. The compressor 100 may further include one fixing member 50. One fixing member 50 may save installation space and facilitate the installation of other parts of the compressor 100. The compressor 100 may further include multiple fixing members 50. The multiple fixing members 50 may be spaced apart on the housing 10 and the terminal cover 30, and may provide fastening force to different parts of the housing 10 and the terminal cover 20, so that the fastening force between the housing 10 and the terminal cover 20 is more balanced.
[0130] The fixing member 50 is used to fix the shell 10 and the terminal cover 20 together, so that the shell 10 and the terminal cover 20 are squeezed in a direction close to each other, so that the terminal cover 20 can be fixed to the shell 10. Using at least one fixing member 50 to fix the terminal cover 20 and the shell 10 can ensure the stability and firmness of the terminal cover 20 fixed to the shell 10.
[0131] The seal 30 is located between the shell 10 and the terminal cover 20. While the fixing member 50 is used to fix the shell 10 and the terminal cover 20, the seal 30 can be squeezed so that the gap between the shell 10 and the seal 30 and the gap between the seal 30 and the terminal cover 20 are further reduced, and the gap between the seal 30 and the connecting wire group 40 can also be reduced at the same time, so that the seal 30 is better sealed between the shell 10, the terminal cover 20 and the connecting wire group 40, so as to improve the sealing performance of the seal 30.
[0132] For example, the fixing member 50 may include a bolt 51 and a nut 52 , or a rivet, etc.
[0133] According to some embodiments of the present application, referring to Figures 1 to 16, the fixing member 50 includes a bolt 51 and a nut 52. The bolt 51 is fixed to the housing 10. For example, the bolt 51 can be integrally formed with the housing 10. A bolt fitting hole is formed on the terminal cover 20. The bolt 51 is passed through the bolt fitting hole and extends from the installation space 21. The nut 52 is used to tighten with the bolt 51 to fix the terminal cover 20 to the housing 10, which can ensure that the terminal cover 20 is firmly fixed to the housing 10.
[0134] The combination of the nut 52 and the bolt 51 can, on the one hand, make the method of fixing the connection between the shell 10 and the terminal cover 20 simple and easy to operate; on the other hand, by loosening the bolt 51, the terminal cover 20 can be removed from the shell 10, which is convenient for repairing the internal structure of the compressor 100; at the same time, the seal 30 can also be removed, which is convenient for replacing the seal 30.
[0135] According to some embodiments of the present application, referring to Figures 16-17, a fixing member matching hole 32 is formed on the seal 30, and a bolt 51 is passed through the fixing member matching hole 32 to limit the position of the seal 30, so as to better position the seal 30 and prevent the seal 30 from moving.
[0136] Specifically, the bolts 51 on the housing 10 are passed through the fixing member fitting holes 32 and the bolt fitting holes to fix the sealing member 30 and the terminal cover 20 to the housing 10 .
[0137] According to some embodiments of the present application, referring to Figures 16-17, the outer periphery of the seal 30 is pressed between the housing 10 and the terminal cover 20 to seal the assembly gap between the housing 10 and the terminal cover 20, so that the seal 30 can better seal the assembly gap between the housing 10 and the terminal cover 20.
[0138] In some specific examples, an angle is formed between the side wall of the terminal cover 20 and the bottom wall of the terminal cover 20, which can be an obtuse angle. The side wall of the terminal cover 20 is aligned with the side surface of the first limiting groove 371, which can limit the seal 30. The terminal cover 20 is then fixed to the housing 10 using bolts 51 and nuts 52, thereby fixing the seal 30 between the housing 10 and the terminal cover 20.
[0139] In other specific examples, the seal 30 may include a first limiting portion 37 and a seal body 34, and the first limiting portion 37 and the seal body 34 may be of separate designs. The terminal sealing ring 38, the terminal assembly hole 33, and the fixing member matching hole 32 are all formed on the seal body 34, and the wire hole 312 is formed on the first limiting portion 37. The terminal sealing ring 38, the terminal assembly hole 33, and the terminal 61 cooperate to limit the seal body 34; the side wall of the terminal cover 20 can be inserted into the first limiting groove 371 of the first limiting portion 37, and then the first limiting portion 37 and the seal body 34 can be fixed using a bolt 51 and a nut 52.
[0140] The wire entry opening of the wire hole 312 has a guide slope that facilitates the passage of the connecting wire assembly 40 through the wire hole 312. Multiple wire holes 312 are provided within the seal 30. The connecting wire assembly 40 includes multiple connecting wires 41. The number of wire holes 312 is equal to the number of connecting wires 41, and the number corresponds one-to-one, facilitating the passage of multiple connecting wires 41 through the wire holes 312. Sealant can be applied between the connecting wires 41 and the inner wall of the wire hole 312 to further seal the connecting wires 41.
[0141] According to some embodiments of the present application, referring to Figures 16-17, the seal 30 has a terminal assembly hole 33 and a terminal sealing ring 38. The terminal sealing ring 38 is arranged on the side of the terminal assembly hole 33 facing the installation space 21. The terminal sealing ring 38 can be connected to the outer peripheral wall of the terminal assembly hole 33.
[0142] The terminal 61 is inserted into the terminal assembly hole 33, and the terminal sealing ring 38 surrounds the outer peripheral side of the terminal 61. When the terminal cover 20 is installed on the shell 10, the terminal cover 20 can be located on the outer peripheral side of the terminal sealing ring 38, and the terminal sealing ring 38 can abut against the terminal 61. The terminal sealing ring 38 can increase the sealing area between the shell 10 and the terminal cover 20, and can further increase the sealing performance of the seal 30; and the terminal 61 can be inserted into the terminal assembly hole 33, and the seal 30 can also be limited by the terminal sealing ring 38 and the terminal assembly hole 33, so that the seal 30 is not easy to move.
[0143] According to some embodiments of the present application, referring to Figures 16 and 17 , the connecting wire assembly 40 includes a plurality of connecting wires 41. Specifically, there may be three connecting wires 41, namely, three-phase wires R, S, and T. The seal 30 is configured with a plurality of wire holes 312 corresponding one to each of the connecting wires 41. Accordingly, there may be three wire holes 312, and the three-phase wires R, S, and T may be installed in the corresponding wire holes 312.
[0144] The connecting wires 41 can be installed into the corresponding wire holes 312 . The number of connecting wires 41 and wire holes 312 can be equal and one-to-one corresponding, which can play a certain fool-proof role and facilitate the installation of the connecting wires 41 into the wire holes 312 .
[0145] The connecting wire 41 can be interference fit with the wire hole 312, which can ensure that the connecting wire 41 is not easy to fall off from the wire hole 312, and it is not easy to generate a gap between the connecting wire 41 and the sealing member 30, which can improve the sealing performance of the sealing member 30.
[0146] According to some embodiments of the present application, at least some of the wire holes 312 are provided with ribs. The ribs may be provided in a portion of the wire holes 312. The wire holes 312 are used to install the connecting wires 41. The ribs provided in a portion of the wire holes 312 can make the diameters of the wire holes 312 different, so that the wire holes 312 can accommodate multiple connecting wires 41 of different diameters. Alternatively, all of the wire holes 312 may be provided with ribs, so that the diameters of the multiple wire holes 312 are the same, so that the wire holes 312 can accommodate multiple connecting wires 41 of the same diameter.
[0147] The ribs can also increase the sealing of the connecting wire 41 without causing excessive compression force, so as to fix the connecting wires 41 of different diameters into the wire hole 312 .
[0148] In some examples, the rib 311 may include a protrusion, and there may be multiple protrusions. The multiple protrusions are arranged at intervals on the wall of the wire hole 312. The protrusions can be arranged in multiple rows and columns on the wall of the wire hole 312, and the heads of the protrusions can be set to be arc transitions. When the connecting wire 41 is installed in the wire hole 312, the sealing force provided by the protrusions to the connecting wire 41 is more balanced, and the protrusions can be prevented from crushing the connecting wire 41.
[0149] In other examples, the rib 311 may include a plurality of spaced-apart convex strips, and one end of the convex strip away from the wall of the wire hole 312 is set as an arc transition. When the connecting wire 41 is installed in the wire hole 312, the convex strip can be prevented from crushing the connecting wire 41.
[0150] According to some embodiments of the present application, the convex rib is in a ring shape surrounding the outer periphery of the connecting wire 41, and the convex rib can be provided on the wall surface of the wire hole 312. When the connecting wire 41 is installed in the wire hole 312, the convex rib can provide a more balanced sealing force for the surrounding wall of the connecting wire 41, so that the connecting wire 41 can be subjected to a more balanced force, and the convex rib is not easy to crush the connecting wire 41.
[0151] The convex rib is annular and surrounds the outer peripheral side of the connecting line 41. The convex rib can abut against the outer peripheral side of the connecting line 41, so that the convex rib is completely sealed on the outer peripheral side of the connecting line 41, avoiding the generation of a gap between the convex rib and the outer peripheral side of the connecting line 41, and improving the sealing performance of the seal 30.
[0152] For example, the end of the rib away from the wall of the wire hole 312 can be set as an arc transition, which can prevent the rib from crushing the connecting wire 41 when the connecting wire 41 is installed in the wire hole 312.
[0153] According to some embodiments of the present application, a plurality of ribs are arranged at intervals along the routing direction of the connecting line 41. The ribs can provide multiple sealing forces for the connecting line 41, prevent the connecting line 41 from shaking in the wire hole 312, and further increase the sealing performance of the sealing member 30 in sealing the connecting line 41.
[0154] According to some embodiments of the present application, the elastic modulus of the rib is lower than that of the seal 30, and the stress of elastic deformation of the seal 30 is greater than that of the rib. In other words, the material stiffness of the seal 30 is greater than that of the rib. Under a certain stress, the deformation of the seal 30 caused by elastic deformation is smaller than that caused by elastic deformation of the rib, meaning that the rib is more susceptible to elastic deformation than the seal 30.
[0155] When the connecting wire 41 is installed in the wire hole 312, the ribs are prone to elastic deformation, and the deformation range of the ribs is relatively large. When the diameter of the connecting wire 41 is larger, the elastic deformation of the ribs varies more, while when the diameter of the connecting wire 41 is smaller, the elastic deformation of the ribs varies less, allowing the seal 30 to seal a variety of connecting wires 41.
[0156] The elastic modulus can be regarded as an indicator to measure the ease with which a material undergoes elastic deformation. The larger its value, the greater the stress required to cause the material to undergo a certain elastic deformation, that is, the greater the material stiffness, and the smaller the elastic deformation under a certain stress.
[0157] According to some embodiments of the present application, referring to Figures 16-18 , a wire harness positioning member 39 is provided on the sealing member 30 to define the path of the connecting wire assembly 40. After the connecting wire assembly 40 is installed in the wire hole 312, the position of the connecting wire assembly 40 can be adjusted. The wire harness positioning member 39 is then used to secure the connecting wire assembly 40 in the adjusted position, thereby limiting the relative position of the connecting wire assembly 40 and the sealing member 30 and preventing the connecting wire assembly 40 from moving or rotating.
[0158] The wire harness positioning member 39 can be set at the wire hole 312 adjacent to the seal 30. After the connecting wire group 40 extends out of the wire hole 312, it can be fixed by the wire harness positioning member 39, which can shorten the distance for fixing the connecting wire group 40 and make the stability of the wire harness positioning member 39 in fixing the connecting wire group 40 higher.
[0159] For example, the harness positioning member 39 may include a fixing portion and a cable tie or cable buckle connected to the fixing portion. The fixing portion may be located adjacent to the cable hole 312 of the sealing member 30. One or more cable ties or cable buckles may be provided. After the connecting wire 41 extends from the cable hole 312, a cable tie or cable buckle may be used to sequentially wrap around the connecting wire 41. After wrapping, the cable tie or cable buckle is secured to the fixing portion. Alternatively, multiple cable ties or cable buckles may be used to sequentially wrap around the connecting wire 41, and the multiple cable ties or cable buckles are secured to the fixing portion. Alternatively, a cable tie or cable buckle may be used to wrap around the corresponding connecting wire 41. The cable tie or cable buckle secures the corresponding connecting wire 41 to the fixing portion after wrapping the corresponding connecting wire 41. This further secures the connecting wire 41 and prevents the connecting wire 41 from moving or rotating, or from falling out of the cable hole 312.
