Embodiments of the present invention

[0055] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0056] This application proposes an integrated terminal 100 for a compressor 1000 with a fault-tolerant design, which can prevent damage to the integrated terminal 100 when it is assembled with the compressor 1000, thereby improving assembly reliability. It also proposes a compressor 1000 including the aforementioned integrated terminal 100, and a heating, ventilation, and air conditioning (HVAC) system including the aforementioned compressor 1000.

[0057] As shown in Figures 1 to 13, the integrated terminal 100 for compressor 1000 according to an embodiment of this application includes a housing 10 and a wiring terminal 20.

[0058] The housing 10 has a mounting cavity 111 and a socket 121 communicating with the mounting cavity 111. A terminal 20 is disposed in the mounting cavity 111. The terminal 20 includes a body portion 22 with a mounting hole 21, which is opposite to the socket 121. The ratio of the dimension W1 of the body portion 22 along the first direction to the dimension W2 of the mounting cavity 111 along the first direction satisfies: 0.6≤W1 / W2≤0.96. The first direction is perpendicular to the axis of the socket 121. This arrangement can prevent damage to the integrated terminal 100 when it is assembled with the compressor body 200, thereby improving the reliability of the assembly.

[0059] Specifically, the compressor body 200 is provided with terminals; when the integrated terminal 100 is assembled with the compressor body 200, the terminals of the compressor body 200 can be inserted into the mounting cavity 111 through the socket 121 and connected to the mounting hole 21 of the terminal 20, thereby realizing the electrical connection between the integrated terminal 100 and the compressor body 200. In addition, in this invention, the ratio of the dimension W1 of the body part 22 along the first direction to the dimension W2 of the mounting cavity 111 along the first direction satisfies: 0.6≤W1 / W2≤0.96, so as to improve the reliability of assembly and avoid damage to the integrated terminal 100.

[0060] Optionally, W1 / W2 can be 0.6, 0.7, 0.8, 0.9, 0.96, etc. Among them, since 0.6≤W1 / W2≤0.96, a deformation allowance can be provided for the terminal 20. When the terminal is inserted into the mounting hole 21, the body part 22 can expand outward of the mounting hole 21 to facilitate the insertion and mating of the terminal and the mounting hole 21. This can improve the stability of the connection structure between the body part 22 and the terminal and ensure a stable electrical connection between the terminal 20 and the terminal.

[0061] According to an embodiment of the present invention, the integrated terminal 100 for the compressor 1000, through the fault-tolerant design between the wiring terminal 20 and the mounting cavity 111, can avoid damage to the integrated terminal 100 when it is assembled on the compressor body 200, thereby improving assembly reliability.

[0062] Referring to Figure 17, the horizontal axis represents the ratio of W1 to W2, and the vertical axis represents the force on the terminals. It shows the assembly of the integrated terminal 100 with the compressor body 200 at different ratios W1 / W2. It can be seen that...

[0063] If W1 / W2 < 0.6, the gap between the main body 22 and the mounting cavity 111 in the first direction is large, the stress on the terminal is small, the stability of the connection between the terminal and the integrated terminal 100 is poor, and a large insertion force is required to achieve a stable connection between the terminal and the integrated terminal 100.

[0064] If W1 / W2 > 0.96, the gap between the main body 22 and the mounting cavity 111 in the first direction is small, and the stress on the wiring terminal is large, which can easily lead to damage to the integrated terminal 100 in practice.

[0065] The housing 10 is made of plastic. The socket 121 can be circular or boat-shaped, etc.

[0066] As shown in Figures 6 and 7, in some embodiments of this application, the socket 121 is configured such that the dimension along the first direction is smaller than the dimension along the second direction, and the first direction, the second direction and the axis of the socket 121 are perpendicular to each other; in this way, the compressor body 200 can be guided to assemble with the integrated terminal 100, thereby improving assembly efficiency.

[0067] Specifically, the shape of the terminal block of the compressor body 200 is adapted to the shape of the socket 121. The terminal block can be inserted into the socket 121 by pressing to make an electrical connection with the terminal block 20 in the mounting cavity 111. The socket 121 is designed with a size smaller in the first direction than in the second direction. In this way, in order to be inserted into the socket 121, the terminal block needs to be matched with the socket 121 at a predetermined angle to guide the compressor body 200 and the integrated terminal 100 to be assembled, thereby improving the assembly efficiency.

[0068] Optionally, the dimensions W1 of the body portion 22 along the first direction and the dimensions W2 of the mounting cavity 111 along the first direction can be set as the dimensions of the cross-sections of the body portion 22 and the mounting cavity 111 along the axis passing through the insertion port and parallel to the first direction; or the dimensions of other cross-sections parallel to the first direction. In some other embodiments, the dimension W1 of the body portion 22 along the first direction can also be set as the maximum dimension of the body portion 22 along the first direction; the dimension W2 of the mounting cavity 111 along the first direction can also be set as the maximum dimension of the body portion 22 along the first direction, etc. The above description is merely some ways of determining the dimensions W1 of the body portion 22 along the first direction and the dimensions W2 of the mounting cavity 111 along the first direction in this invention, and is not intended to limit the scope of protection of this invention.

[0069] Furthermore, in some specific examples, the mounting hole 21 is also designed with a dimension along the first direction smaller than that along the second direction, to limit the insertion of the terminal block into the mounting hole 21 at a predetermined angle. The body portion 22 of the terminal block 20 is assembled in the mounting cavity 111 along the second direction, and satisfies the following relationship with the mounting cavity 111 in the first direction: 0.6 ≤ W1 / W2 ≤ 0.96, to improve assembly reliability and avoid damage to the integrated terminal block 100. In other specific examples, the body portion 22 is also designed with a dimension along the first direction smaller than that along the second direction, so that the terminal block 20 can be assembled in the mounting cavity 111. It is understood that the dimension of the body portion 22 along the second direction is larger. Therefore, one end of the body portion 22 along the second direction can be connected to the power harness 30. The body portion 22 is assembled in the mounting cavity 111 along the second direction, and the dimension W1 of the body portion 22 along the first direction and the dimension W2 of the mounting cavity 111 along the first direction satisfy 0.6 ≤ W1 / W2 ≤ 0.96, to improve assembly reliability.

[0070] As shown in Figures 1 and 2, in some embodiments of this application, the body portion 22 is configured as a semi-closed or fully closed ring. The ring-shaped body portion 22 facilitates the assembly of the wiring terminal 20 into the mounting cavity 111, reduces the wear between the wiring terminal 20 and the inner wall of the mounting cavity 111, and improves assembly efficiency. The main body 22 includes a first piece 221, a second piece 222, and a transition portion 223. The first piece 221 and the second piece 222 are integrally connected through the transition portion 223. The first piece 221, the second piece 222, and the transition portion 223 can be integrally connected by processes such as stamping and welding to improve the structural strength of the terminal 20 and prevent damage to the terminal 20. The first piece 221, the second piece 222, and the transition portion 223 surround the aforementioned mounting hole 21. The first piece 221 and the second piece 222 are opposite to each other in a first direction. The first piece 221 has a first outer wall away from the second piece 222, and the second piece 222 has a second outer wall away from the first piece 221. The maximum distance between the first outer wall and the second outer wall is set to dimension W1.

[0071] Furthermore, the first portion 221, the second portion 222, and / or the transition portion 223 are configured as straight segments and / or curved segments. For example, the first portion 221 and the second portion 222 can be configured as straight segments, and the transition portion 223 can be configured as a curved segment bridging the first portion 221 and the second portion 222; or the first portion 221 and the second portion 222 can be configured as curved segments, and the transition portion 223 can be configured as a curved segment bridging the first portion 221 and the second portion 222; or the first portion 221 and the second portion 222 can be configured as curved segments, and the transition portion 223 can be configured as a straight segment bridging the first portion 221 and the second portion 222. Of course, the above description is merely some implementations of the present invention and is not intended to limit the scope of protection of the present invention.

[0072] As shown in Figure 4, in some embodiments of this application, the mounting cavity 111 has a first inner cavity wall that mates with the first outer wall and a second inner cavity wall that mates with the second outer wall. The maximum distance between the first inner cavity wall and the second inner cavity wall is set to W2. Therefore, the ratio of the maximum distance W1 between the first outer wall and the second outer wall of the body part 22 to the maximum distance W2 between the first inner cavity wall and the second inner wall of the mounting cavity 111 satisfies: 0.6≤W1 / W2≤0.96, which can realize the assembly fault tolerance between the integrated terminal 100 and the compressor body 200 and avoid damage to the integrated terminal 100.

[0073] As shown in Figure 5, in some embodiments of this application, the maximum depth of the body portion 22 along the axial direction of the socket 121 is set as H1, and the dimension of the mounting cavity 111 along the axial direction of the socket 121 is set as H2. The ratio of H1 to H2 satisfies: H1 / H2≤1. This provides an installation margin for the body portion 22 within the mounting cavity 111, and prevents stress from being generated in the body portion 22, which could damage the terminal block 20, if the positional accuracy is not met. The ratio of H1 to H2 can be 1, 0.96, 0.9, 0.8, 0.85, 0.7, 0.65, 0.6, etc.

[0074] As shown in Figures 3 and 9, in some embodiments of this application, the socket 121 has a first end 122 near the mounting cavity 111 and a second end 123 away from the mounting cavity 111. The socket 121 is flared from the first end 122 to the second end 123, including but not limited to: the entire socket 121 being flared from the first end 122 to the second end 123; or a portion of the socket 121 along the axial direction being flared in the direction from the first end 122 to the second end 123, etc. Thus, when the terminal of the compressor body 200 is inserted into the socket 121, the flared socket 121 can guide the insertion of the terminal, thereby improving the assembly efficiency of the integrated terminal 100 and the compressor body 200.

[0075] As shown in Figure 6, in some embodiments of this application, the minimum dimension of the mounting hole 21 along the first direction is set to W3, and the minimum dimension of the first end 122 of the socket 121 along the first direction is set to W4. The ratio of W3 to W4 satisfies: 0.55≤W3 / W4≤0.95. This setting can avoid damage to the integrated terminal 100 when assembling the integrated terminal 100 with the compressor body 200, thereby improving assembly reliability.

[0076] Specifically, when the integrated terminal 100 is assembled with the compressor body 200, the terminals of the compressor body 200 can be inserted into the mounting cavity 111 through the socket 121 and pressed into the mounting hole 21 to achieve electrical connection between the terminal 20 and the compressor body 200. However, due to the fit between the integrated terminal 100 and the compressor body 200, the integrated terminal 100 is easily damaged by force. Therefore, the minimum size of the mounting hole 21 can be set to W3 in the straight direction along the axis of the socket 121, and the minimum size of the first end 122 of the socket 121 can be set to W4. The ratio of W3 to W4 satisfies: 0.55≤W3 / W4≤0.95, so as to improve the reliability of the assembly and avoid damage to the integrated terminal 100. Since 0.55≤W3 / W4≤0.95, when the terminal is inserted into the mounting hole 21, the terminal can cause the body part 22 to elastically deform, so as to facilitate the insertion and mating of the terminal and the mounting hole 21. This can improve the stability of the connection structure between the body part 22 and the terminal, and ensure a stable electrical connection between the terminal 20 and the terminal.

[0077] Among them, W3 / W4 can be 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, etc.

[0078] Referring to Figure 18, the horizontal axis represents the ratio of W3 to W4, and the vertical axis represents the terminal insertion force. It shows the assembly of the integrated terminal 100 with the compressor body 200 with different ratios of W3 / W4. It can be seen that if W3 / W4 is in the range of 0.55 to 0.95, the required terminal insertion force is smaller. However, if W3 / W4 is less than 0.55 or greater than 0.95, the required terminal insertion force is larger and increases abruptly, which can easily lead to damage to the integrated terminal 100 in practice.

[0079] Optionally, the minimum dimension of the first end 122 of the socket 121 is set to W4 and the minimum dimension of the mounting hole 21 is set to W3. These dimensions can be the dimensions of the cross-sections of the socket 121 and the mounting hole 21 passing through the axis of the socket and parallel to the first direction; or the dimensions of other cross-sections parallel to the first direction. The above description is merely one way to determine the minimum dimension of the first end 122 of the socket 121 as W4 and the minimum dimension of the mounting hole 21 as W3 in this invention, and is not intended to limit the scope of protection of this invention.

[0080] As shown in Figure 6, in some embodiments of this application, the maximum dimension of the second end 123 of the socket 121 along the first direction is set to W5, and the ratio of W4 to W5 satisfies: 1.1≤W5 / W4≤2. In this way, the assembly success rate of the integrated terminal 100 and the compressor body 200 can be improved, thereby improving the assembly efficiency.

[0081] Furthermore, referring to Figure 19, the horizontal axis represents the ratio of W5 to W4, and the vertical axis represents the assembly success rate. It shows the assembly of the integrated terminal 100 and the compressor body 200 with different ratios W5 / W4. It can be seen that when W5 / W4 is in the range of 1.1 to 2, the assembly success rate of the integrated terminal 100 and the compressor body 200 is relatively high. However, when W5 / W4 is less than 1.1 or greater than 2, the assembly success rate of the integrated terminal 100 and the compressor body 200 is relatively low, which affects the assembly efficiency in practice.

[0082] It is understood that the socket 121 extends away from the mounting cavity 111 and has a first end 122 close to the mounting cavity 111 and a second end 123 away from the mounting cavity 111. The first end 122 of the socket 121 has a dimension of W4 along the first direction, and the second end 123 of the socket 121 has a maximum dimension of W5 along the first direction. The ratio of W4 to W5 satisfies: 1.1≤W5 / W4≤2, so that the inner wall of the socket 121 gradually expands in the direction from the first end 122 to the second end 123, forming an flared shape of the socket 121 from the first end 122 to the second end 123, so as to guide the terminal to be inserted into the socket 121 and improve the assembly success rate.

[0083] Conversely, if W5 / W4 < 1.1, the inner wall of the socket 121 is of equal diameter or gradually narrows in the direction from the first end 122 to the second end 123, which cannot guide the terminal block into the socket 121 and affects the success rate of the assembly of the integrated terminal 100 and the compressor body 200; if W5 / W4 > 2, the inner wall of the socket 121 is almost flush with the outer surface of the housing 10, which cannot guide the terminal block.

[0084] As shown in Figures 11 to 13, in some embodiments of this application, a second cavity 1112 is provided on the side of the mounting cavity 111 near the socket 121. The minimum dimension W6 of the second cavity 1112 along the first direction and the dimension W2 of the mounting cavity 111 along the first direction satisfy: W6 < W2. In this way, pre-positioning can be performed through the second cavity 1112, thereby improving the assembly efficiency of the terminal 20 in the mounting cavity 111.

[0085] Specifically, during the assembly of the integrated terminal 100, the wiring terminal 20 can be pre-assembled in the second cavity 1112. The second cavity 1112 pre-positions the wiring terminal 20, and after the remaining parts of the wiring terminal 20 are assembled, it can be assembled in the mounting cavity 111. This improves the assembly efficiency of the integrated terminal 100. Therefore, it can be understood that the minimum dimension of the mounting cavity 111 along the first direction is W2, and the minimum dimension of the second cavity 1112 along the first direction is W6, satisfying W6 < W2. This facilitates the pre-positioning of the wiring terminal 20 in the second cavity 1112 before assembly in the mounting cavity 111, thus improving assembly efficiency.

[0086] Generally, the terminals of the compressor body 200 are cylindrical to facilitate electrical connection between the terminal block 20 and the terminal block; therefore, as shown in the figure, in some embodiments of this application, the socket 121 is set to a circular shape so that the terminal block can be adapted to the structure of the socket 121 and facilitate the insertion of the terminal block into the socket 121.

[0087] In some other embodiments of this application, the socket 121 includes a first edge portion, a second edge portion, a third edge portion and a fourth edge portion, wherein the first edge portion, the second edge portion, the third edge portion and the fourth edge portion are arc-shaped; in this way, the terminal can be adapted to the structure of the socket 121, making it easy for the terminal to be inserted into the socket 121.

[0088] As shown in Figure 15, in some embodiments of this application, the integrated terminal 100 of the compressor 1000 also includes a power harness 30, which is connected to the terminal block 20. Specifically, one end of the power harness 30 is connected to a power source, and the other end is connected to the terminal block 20. When the integrated terminal 100 is assembled on the compressor body 200, the terminals of the compressor body 200 are electrically connected to the terminal block 20. In this way, the compressor body 200 can be connected to a power source to supply power to the compressor body 200 and ensure the normal operation of the compressor body 200.

[0089] In some embodiments of this application, the housing 10 and the compressor body 200 are connected by fasteners; specifically, the housing 10 is provided with a first connection hole, the compressor body 200 is provided with a second connection hole, and the fasteners are respectively passed through the first connection hole and the second connection hole, and the first connection hole and the second connection hole are connected together, thereby connecting the housing 10 to the compressor body 200.

[0090] As shown in Figure 14, in some embodiments of this application, the integrated terminal 100 of the compressor 1000 further includes a first sealing member 40. The first sealing member 40 is disposed on the housing 10 and is used to seal the gap between the housing 10 and the compressor 1000. In this way, the sealing performance of the compressor 1000 can be improved by the first sealing member 40, preventing pollutants from the external environment from entering the interior of the compressor 1000 through the gap between the integrated terminal 100 and the compressor body 200, thereby improving the working performance of the compressor 1000.

[0091] As shown in Figures 7, 8, and 15, in some embodiments of this application, the housing 10 includes an inner structure 11 and an outer structure 12. The inner structure 11 is fixedly connected to the terminal 20, serving to fix and protect the terminal 20. The outer structure 12 encloses the inner structure 11 and the terminal 20, so as to fix the outer structure 12, the inner structure 11, and the terminal 20 together. The socket 121 is provided on the outer structure 12 and is opposite to the terminal 20. The terminal of the compressor 1000 passes through the socket 121 and is electrically connected to the terminal 20. The connection position between the terminal and the terminal 20 is located inside the outer structure 12. The inner layer structure 11 can fix the wiring terminal 20. When the outer layer structure 12 wraps around the inner layer structure 11, it ensures that the position of the wiring terminal 20 connected to the inner layer structure 11 is relatively fixed, avoiding the problem of the wiring terminal 20 shifting or becoming loose during the docking of the integrated terminal 100 and the compressor 1000, thereby improving the structural stability of the integrated terminal 100. In addition, using the outer layer structure 12 to wrap around the inner layer structure 11 can facilitate the relative isolation of the inner layer structure 11 and the wiring terminal 20 from the external environment, making it easier to waterproof and dustproof the wiring terminal 20.

[0092] Additionally, the integrated terminal 100 may include multiple terminals 20. For different types of compressors 1000, it may have two, three, or four terminals. The multiple terminals 20 are enclosed within the terminal body. To facilitate the connection between the integrated terminal 100 and the terminals, the relative positions of these multiple terminals 20 need to be defined. Specifically, the multiple terminals 20 can be positioned by the inner layer structure 11, and the inner layer structure 11 and the terminals 20 can be enclosed by the outer layer structure 12. This prevents the multiple terminals 20 from shifting when the outer layer structure 12 encloses the inner layer structure 11, thus facilitating the connection between the compressor 1000's terminals and the multiple terminals 20.

[0093] In some embodiments of this application, the inner layer structure 11 and the outer layer structure 12 are formed separately; or, the inner layer structure 11 is injection molded, and the outer layer structure 12 is injection molded with the inner layer structure 11 in a secondary process. For example, the outer layer structure 12 can be injection molded with the inner layer structure 11 after the inner layer structure 11 is injection molded. This allows the inner layer structure 11 to maintain the position of the terminal 20, preventing the terminal 20 from shifting during the secondary injection molding process, and providing deformation allowance for the terminal 20, facilitating the connection between the terminal post and the terminal 20. The secondary injection molding of the outer layer structure 12 ensures the waterproof and dustproof properties of the inner layer structure 11 and the terminal 20, improving the stability of the integrated terminal 100.

[0094] In conjunction with the foregoing, the manufacturing method of the integrated terminal 100 in this application embodiment can be as follows: connecting the wiring terminal 20 to the power harness 30; manufacturing an inner layer structure 11 with a mounting cavity 111, installing the wiring terminal 20 in the mounting cavity 111, and extending the power harness 30; positioning the inner layer structure 11 with the wiring terminal 20 installed in a mold, and injection molding an outer layer structure 12 on the outside of the inner layer structure 11, the outer layer structure 12 wrapping the inner layer structure 11, the wiring terminal 20 and a part of the power harness 30, and constructing a socket 121 on the outer layer structure 12 during the injection molding process, the socket 121 being opposite to the wiring terminal 20.

[0095] In some embodiments of this application, the inner layer structure 11 is a block made of PBT (polybutylene terephthalate) material mixed with flame retardant; or, the outer layer structure 12 is a block made of PBT material mixed with flame retardant. This ensures the flame-retardant performance of the integrated terminal 100 and improves its stability and safety. Alternatively, the inner layer structure 11 can also be a block made of PVC (polyvinyl chloride) material or nylon material; the outer layer structure 12 can also be a block made of PVC material or nylon material. PVC material provides the integrated terminal 100 with good waterproof performance, durability, and insulation performance; nylon material has high strength and good durability, which can improve the structural strength of the integrated terminal 100.

[0096] As shown in Figures 1 to 16, the compressor 1000 according to the embodiments of this application includes a compressor body 200 and an integrated terminal 100 for the compressor 1000 in the above embodiments. The integrated terminal 100 for the compressor 1000 is disposed on the compressor body 200. By using the integrated terminal 100 for the compressor 1000, the structural stability of the compressor 1000 can be improved, thereby improving the working performance of the compressor 1000.

[0097] Specifically, during assembly, the terminals of the compressor body 200 can pass through the housing 10 of the integrated terminal 100 and be inserted into the mounting holes 21 of the terminal 20 in the mounting cavity 111, thus achieving electrical connection between the integrated terminal 100 and the compressor body 200. The terminal 20 can be connected to the power harness 30. In this way, the integrated terminal 100 can supply power to the compressor body 200, and the integrated terminal 100 facilitates electrical connection between the compressor body 200 and an external power source, improving assembly convenience. However, during assembly, due to the fit between the compressor body 200 and the integrated terminal 100, the integrated terminal 100 is easily damaged. Therefore, this application proposes an integrated terminal 100 for a compressor 1000 with a fault-tolerant design, which can be applied to the compressor 1000.

[0098] More specifically, the ratio of the dimension W1 of the body portion 22 of the terminal block 20 along the first direction to the dimension W2 of the mounting cavity 111 along the first direction satisfies: 0.6 ≤ W1 / W2 ≤ 0.96. This provides space for the terminal block 20 within the mounting cavity 111, preventing excessive stress on the terminal block 20 in case of misalignment during assembly, and avoiding the need for excessive insertion force when connecting the terminal block to the mounting hole 21, which could damage the terminal block 20. Furthermore, the ratio of the maximum depth H1 of the body portion 22 along the axis of the socket 121 to the dimension H2 of the mounting cavity 111 along the axis of the socket 121 satisfies: H1 / H2 ≤ 1, preventing excessive stress on the terminal block 20 in case of misalignment.

[0099] Furthermore, the socket 121 is flared from the first end 122 to the second end 123 to guide the terminal into the socket 121, improving assembly efficiency. Additionally, the ratio of the minimum dimension W3 of the mounting hole 21 along the first direction to the minimum dimension W4 of the first end 122 of the socket 121 along the first direction satisfies: 0.55 ≤ W3 / W4 ≤ 0.95, to improve assembly reliability and prevent damage to the integrated terminal 100. Moreover, the ratio of the maximum dimension W5 of the second end 123 of the socket 121 along the first direction to the minimum dimension W4 of the first end 122 of the socket 121 along the first direction satisfies: 1.1 ≤ W5 / W4 ≤ 2, to guide the terminal into the socket 121, thereby improving the success rate of assembling the integrated terminal 100 with the compressor body 200.

[0100] Furthermore, the mounting cavity 111 includes a second cavity 1112 on the side near the socket 121. The minimum dimension W6 of the second cavity 1112 along the first direction and the dimension W2 of the mounting cavity 111 along the first direction satisfy: W6 < W2, so that during installation, the wiring terminal 20 is first pre-positioned in the second cavity 1112 and then placed in the mounting cavity 111 to complete the assembly.

[0101] Optionally, the minimum dimension W6 of the second cavity 1112 along the first direction and the dimension W2 of the mounting cavity 111 along the first direction can be set as the dimensions of the cross-sections of the second cavity 1112 and the mounting cavity 111 along the axis passing through the insertion port and parallel to the first direction; or the dimensions of other cross-sections parallel to the first direction. The above description is merely some ways of determining the minimum dimension W6 of the second cavity 1112 along the first direction and the dimension W2 of the mounting cavity 111 along the first direction in this invention, and is not intended to limit the scope of protection of this invention.

[0102] As shown in Figures 14 to 16, in some embodiments of this application, the compressor 1000 further includes a temperature sensor assembly 300. The temperature sensor assembly 300 includes a housing 310, a temperature sensing element 320, and a second sealing element 330. The temperature sensing element 320 is disposed inside the housing 310, and the second sealing element 330 is disposed on the housing 310 and used to seal the gap between the housing 310 and the compressor 1000. Specifically, the housing 310 is disposed on the outer surface of the compressor body 200, the temperature sensing element 320 can contact the outer surface of the compressor body 200 to sense the temperature of the compressor body 200, and the second sealing element 330 can be disposed on the housing 310 and seal the gap between the housing 310 and the compressor 1000.

[0103] Furthermore, the outer casing 310 and the housing 10 are integrally formed by injection molding to improve the overall structural strength of the compressor 1000 and facilitate the assembly of the temperature sensor assembly 300 and the integrated terminal 100 onto the compressor body 200, thereby improving assembly efficiency. In addition, in some specific examples, the first seal 40 and the second seal 330 are integrally formed, which can further improve assembly efficiency.

[0104] As shown in Figure 16, in some embodiments of this application, the compressor 1000 uses an integrated terminal 100 disposed on the outer surface of the compressor body 200; specifically, the housing 10 is disposed on the outer surface of the compressor body 200, and the socket 121 of the housing 10 is opposite to the outer surface of the compressor body 200, so that the terminals of the compressor body 200 can be inserted into the socket 121 to realize the electrical connection between the integrated terminal 100 and the compressor body 200.

[0105] According to the embodiments of this application, the HVAC equipment includes the compressor 1000 in the above embodiments. By using the compressor 1000, the structural stability of the HVAC equipment can be improved, thereby improving the working performance of the HVAC equipment.

[0106] The integrated terminal 100 may have a through hole, which mates with a bolt post of the compressor body 200 for fixing the integrated terminal 100. The integrated terminal 100 has an elastic element that contacts the upper housing of the compressor body 200.
