[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where 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 drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0042] As Figure 1 shown, according to Embodiment of the present invention, the terminal assembly 1 of a compressor, the terminal assembly 1 is used to connect to the compressor body. The terminal assembly 1 includes: a housing 11 and a seal 12. The housing 11 has a mating surface for mating with the compressor body. When the housing 11 is mounted on the compressor body, the mating surface of the housing 11 faces the surface of the compressor body; the seal 12 is provided on the mating surface for sealing the gap between the housing 11 and the compressor body, and the seal 12 is fixedly connected to the housing 11 relatively.

[0043] It should be noted that "relatively fixed" means that when the seal 12 is mounted on the mating surface of the housing 11, the seal 12 and the housing 11 cannot move relative to each other. For example, the seal 12 cannot displace relative to the housing 11 in a linear direction parallel to the mating surface, a rotational direction parallel to the mating surface, and a direction perpendicular to the mating surface. Of course, this fixation is relative. When the external force received by the seal 12 is large enough, it will fall off the housing 11.

[0044] Specifically, the housing 11 has a mating surface, the seal 12 is provided on the mating surface, the seal 12 and the housing 11 are arranged to be fixedly connected relatively. After the two are connected, the seal 12 and the housing 11 are relatively fixed, and it is difficult for the seal 12 to fall off the mating surface of the housing 11.

[0045] The terminal assembly 1 of the compressor of the present application can pre-install the seal 12 on the cover body 11 during the production process, or manually pre-install the seal 12 on the cover body 11. During assembly, the terminal assembly 1 of the compressor can be directly connected to the compressor body. When the cover body 11 is fixedly connected to the compressor body, the seal 12 will also provide a sealing effect between the cover body 11 and the compressor body. Therefore, during the process of installing the terminal assembly on the compressor body, there is no need to install the seal separately, thereby simplifying the steps of assembling the terminal assembly and the compressor body.

[0046] The cover body and the seal in the present invention can be assembled together in different ways. For example, the cover body and the seal can be bonded, welded, interference fit, snap-fitted, etc. The assembly method between the cover body and the seal can be set according to actual needs. The present invention provides some explanations on the assembly method of the cover body and the seal, but this is not a limitation on the scope of protection of the present invention.

[0047] According to some embodiments of the present invention, Figure 2 and Figure 3 The cover body 11 has a first positioning structure 111 , and the sealing member 12 has a second positioning structure 121 . The second positioning structure 121 cooperates with the first positioning structure 111 to relatively and fixedly connect the sealing member 12 and the cover body 11 .

[0048] It can be understood that when the second positioning structure 121 of the seal 12 cooperates with the first positioning structure 111 of the cover 11, the seals 12 are in contact with each other and are relatively fixedly connected, further improving the effect of relatively fixing the seal 12 and the cover 11. The first positioning structure and the second positioning structure can cooperate to form a snap connection mechanism, an interference fit mechanism or an adhesive mechanism, etc.

[0049] Optionally, a first positioning structure 111 can be set on the side of the cover body or on the surface away from the mating surface, and a second positioning structure matched with the first positioning structure 111 can be set to form a connection by snapping, bonding or welding to achieve a stable connection between the seal and the cover body.

[0050] In addition, the first positioning structure 111 can be arranged on the mating surface, and the second positioning structure 121 can be opposite to and assembled with the first positioning structure 111 along the normal direction of the mating surface. This facilitates the stable and rapid mating between the first positioning structure 111 and the second positioning structure 121. When the seal is assembled with the cover, it is only necessary to install the seal on the cover along the normal direction of the mating surface, thereby effectively optimizing the assembly efficiency and stability of the cover and the seal. Moreover, when the cover is installed on the compressor body, the seal can be used to provide a stable and effective seal between the cover and the compressor body.

[0051] It can be understood that after the second positioning structure 121 and the first positioning structure 111 are opposite to each other along the normal direction and assembled, the seal 12 contacts the seal 12 and is fixedly connected relatively, further improving the effect of the relative fixation between the seal 12 and the cover 11.

[0052] According to some embodiments of the present invention, in combination with Figure 4 and Figure 5 , the first positioning structure 111 includes a groove 1111, and the second positioning structure 121 includes a boss 1211 that cooperates with the groove 1111. The boss 1211 is embedded and installed in the groove 1111. An interference fit structure can be configured between the boss 1211 and the groove 1111 to achieve a stable fit between the boss 1211 and the groove 1111, realize the stable installation between the seal and the cover, and the assembly efficiency between the seal and the cover is higher. In addition, through the cooperation of the boss and the groove, the sealing surface affecting the seal can be sealed, avoiding the influence on the sealing effect between the seal and the cover and the compressor body during the assembly process of the seal and the cover.

[0053] It can be understood that when the boss 1211 is embedded in the groove 1111, the first positioning structure 111 and the second positioning structure 121 are assembled. At this time, the seal 12 contacts the seal 12 and is fixedly connected relatively, further improving the effect of the relative fixation between the seal 12 and the cover 11.

[0054] According to some embodiments of the present invention, the seal 12 is set as an elastic structure, which can effectively improve the sealing effect between the cover and the compressor body. In addition, when the boss 1211 is embedded in the groove 1111, it undergoes elastic deformation, and the boss 1211 and the groove 1111 are in interference fit. A stable fit between the boss and the groove is achieved, preventing the boss 1211 from falling off after being connected to the groove 1111, further improving the effect of the relative fixation between the seal 12 and the cover 11, and effectively improving the stability of the fit between the cover and the seal 12.

[0055] According to some embodiments of the present invention, the width dimension of the boss 1211 is not less than the width dimension of the groove 1111. Wherein, the seal of the present invention may include a sealing portion, and the sealing portion is set as an annular structure to achieve the sealing between the cover and the compressor body. A sealed space is formed inside the sealing portion. In addition, the boss may be provided on the sealing portion. The width dimension of the boss is the dimension along the circumference of the seal, and the width of the groove may be a dimension corresponding to the width of the boss. Since the width dimension of the boss is not less than the width dimension of the groove, it is convenient for the boss to be installed in the groove by interference fit, effectively improving the assembly stability between the seal and the cover.

[0056] In addition, in combination with Figure 3 and Figure 5, a stress groove 1210 is provided on the boss, which is used to be extruded and deformed towards the stress groove when the boss is embedded in the groove, and the stress groove can be provided in the middle of the boss along the circumference of the seal 12.

[0057] According to some embodiments of the present invention, the seal 12 includes at least one sealing portion 122, the sealing portion 122 is configured to be annular, the boss 1211 is connected to the sealing portion 122, and is configured to have a shape with a changing width dimension in the radial direction of the sealing portion 122, and the shape of the groove 1111 is adapted to the shape of the boss 1211.

[0058] It can be understood that both the boss 1211 and the groove 1111 are configured to have a shape with a changing width dimension in the radial direction of the sealing portion 122. Further, after the boss 1211 and the groove 1111 are matched, the boss 1211 and the groove 1111 are relatively fixedly connected. In addition, through the change in the width of the boss 1211 in the radial direction, the displacement of the boss 1211 relative to the groove in the radial direction can be realized, the radial positioning of the boss 1211 and the groove can be realized, and the stable connection between the seal and the cover can be improved.

[0059] Among them, the width dimension of the boss 1211 in the radial direction can be set such that the width dimension gradually decreases, gradually increases, first increases and then decreases, or first decreases and then increases from the inside to the outside along the radial direction of the sealing portion 122, etc., which can realize the radial positioning of the boss 1211 and the groove 1111 and improve the stability of the connection between the seal and the cover.

[0060] According to some embodiments of the present invention, the projection of the boss 1211 on the normal of the mating surface is rectangular, trapezoidal, triangular or semi-circular. For example, the boss 1211 can be set in a rectangular shape, where the long side of the rectangle can be set to extend along the aforementioned radial direction, and the short side is set perpendicular to the radial direction; the boss can also be set in a trapezoidal, triangular or semi-circular shape, etc. Among them, the boss can include a first side and a second side opposite to each other along the circumference, and the first side and the second side gradually expand in the direction from the inside to the outside. By setting the boss in a trapezoidal, triangular or semi-circular shape, etc., the stable cooperation between the boss and the groove can be realized, and the radial cooperation limit between the boss and the groove can be realized.

[0061] It can be understood that the boss 1211 is configured to extend along the normal of the mating surface along the projection on the mating surface. When the projection of the boss 1211 on the normal of the mating surface is rectangular, trapezoidal, triangular or semi-circular, since the shape of the groove 1111 is adapted to the shape of the boss 1211, the relative fixation between the groove 1111 and the boss 1211 is further realized after the groove 1111 and the boss 1211 are matched.

[0062] Such as Figure 5As shown, in some embodiments of the present invention, the seal 12 may include a sealing portion 122, and a plurality of bosses are provided on the sealing portion. The plurality of bosses may be arranged at intervals along the circumferential direction of the sealing portion. One of the bosses is arranged as a sector with a central angle of 40° (which may be between 25° and 90°), another boss may also be arranged as a sector with a central angle of 40°, and still another boss is arranged in the shape of a rectangle.

[0063] It can be understood that the boss 1211 is provided with a stress groove 1210. When the boss 1211 is fitted with the groove, the boss 1211 elastically deforms in the direction of the stress groove 1210, facilitating the insertion of the boss 1211 into the groove 1111. At the same time, the stress groove disperses the stress points that are too concentrated after the boss 1211 and the groove 1111 are fitted, forming new stress concentration points on the boss 1211, thereby reducing and avoiding damage and deformation to the boss 1211 caused by the overly concentrated stress when the boss 1211 and the groove 1111 are fitted.

[0064] According to some embodiments of the present invention, as Figure 3 shown, the seal 12 includes at least one sealing portion 122. The sealing portion 122 is configured to be annular, and a second positioning structure 121 or a plurality of second positioning structures 121 arranged at intervals along the circumferential direction are provided on the sealing portion 122.

[0065] It can be understood that the sealing portion 122 is configured to be annular, and the annular middle cover body 11 communicates with the compressor body, further realizing the connection between the cover body 11 and the compressor body. At the same time, a second positioning structure 121 is provided on the sealing portion 122, further realizing the relatively fixed connection between the seal 12 and the cover body 11, or a plurality of second positioning structures 121 are arranged at intervals along the circumferential direction of the annular sealing portion 122. By relatively fixedly connecting the plurality of second positioning structures 121 with the first positioning structure 111 one by one, the relatively fixed effect after the connection between the seal 12 and the cover body 11 is further improved.

[0066] According to some embodiments of the present invention, the seal 12 is integrally formed. It can be understood that the integral formation of the seal 12 further shortens the production and manufacturing time of the seal 12 and improves production efficiency.

[0067] According to some embodiments of the present invention, as Figure 3 shown, the seal 12 includes a connecting portion 123 and at least two sealing portions 122. The at least two sealing portions 122 are connected by the connecting portion 123.

[0068] It can be understood that the at least two sealing portions 122 are used to seal the gaps between the mating surfaces of the cover body 11 corresponding to the at least two sealing portions 122 and the compressor body. The plurality of sealing portions 122 are connected by the connecting portion 123, facilitating assembly.

[0069] According to some embodiments of the present invention, as Figure 4 shown, the cover 11 includes a rib 112, the rib 112 extends along the periphery of the mating surface, the seal 12 includes at least one sealing portion 122, the sealing portion 122 is configured to be annular, the sealing portion 122 includes a first annular portion 1221 and a second annular portion 1222, the first annular portion 1221 and the second annular portion 1222 are arranged along the normal direction of the mating surface, the first annular portion 1221 is embedded inside the rib 112, and the second annular portion 1222 protrudes radially outward from the outer periphery of the first annular portion 1221 and faces the rib 112 along the normal direction.

[0070] It can be understood that when the seal 12 is connected to the cover 11, the first annular portion 1221 is embedded inside the rib 112 for sealing the mating surface of the cover 11. At this time, it is difficult for the first annular portion 1221 to have a radial displacement. The second annular portion 1222 faces and contacts the rib 112 for sealing the gap between the rib 112 and the compressor body, further improving the relative fixation effect after the seal 12 is connected to the cover 11.

[0071] According to some embodiments of the present invention, as Figure 4 shown, the cover 11 includes a rib 112, the rib 112 extends along the periphery of the mating surface and constructs a drainage groove 114 communicating the inside and the outside of the rib 112. The cover 11 is provided with a mounting hole 113, the drainage groove 114 corresponds to the mounting hole 113, and the seal 12 constructs a channel on the mating surface communicating the drainage groove 114 and the mounting hole 113.

[0072] It can be understood that when liquid enters from the mounting hole 113, it reaches the drainage groove through the channel communicating the drainage groove and the mounting hole 113, and then the liquid is discharged from the mounting hole 113 through the drainage groove 114, further realizing the drainage of the mounting hole 113.

[0073] According to some embodiments of the present invention, the seal 12 and the cover 11 are adhesively connected by glue. It can be understood that when the glue is applied to the mating surface of the cover 11 and the seal 12 is fixedly connected to the cover 11 relatively, the mating surfaces of the seal 12 and the cover 11 are adhesively connected, further realizing the fixation of the seal 12 and the cover 11.

[0074] According to some embodiments of the present invention, as Figure 6 shown, the terminal assembly 1 further includes a functional component and a connection wire harness 14. The functional component is arranged inside the cover 11. One end of the connection wire harness 14 is located inside the cover 11 for electrically connecting the functional component, and the other end extends out of the cover 11. A part of the connection wire harness 14 is wrapped by the cover 11 to form a sealing structure.

[0075] It can be understood that one end of the connection wire harness 14 is located inside the housing 11 for electrically connecting functional components. The housing 11 isolates liquid and dust. Since the housing 11 covers the outside of the functional components, it prevents liquid and dust from causing harmful effects on the functional components. The seal 12 is used to seal the gap between the housing 11 and the compressor body, further realizing the waterproof and dustproof function of the housing 11 for the functional components. At the same time, the other end of the connection wire harness extends out of the housing 11, and a part of the connection wire harness is wrapped by the housing 11 to form a sealing structure.

[0076] The aforementioned functional components can be a terminal 13 or a temperature sensing component 16.

[0077] For example, in combination with Figure 6 , Figure 7 and Figure 8 , in some embodiments of the present invention, the terminal assembly further includes a terminal 13, and the terminal 13 is arranged inside the housing 11. An inner cavity 1101 can be provided inside the housing 11, and the terminal 13 is arranged in the inner cavity. As shown in Figure 7 , the mating surface has a socket 115, and the socket 115 is arranged on the mating surface for the connection post of the compressor to be inserted and electrically connected to the terminal. The seal 12 includes a first sealing portion 1223 arranged in a ring around the socket 115.

[0078] It can be understood that the terminal is arranged in the inner cavity 1101, and the housing 11 blocks water vapor, liquid and dust from entering and causing harmful effects on the terminal, further realizing the waterproof and dustproof function of the housing 11 for the terminal. When the connection post of the compressor is inserted into the socket 115, it is electrically connected to the terminal. At this time, the housing 11 cooperates with the compressor, and the first sealing portion 122 of the seal 12 seals the gap between the housing 11 and the compressor. During the assembly process, only the terminal assembly 1 needs to be installed on the compressor body, the connection post 11 passes through the socket 115 and extends into the inner cavity 1101, and is electrically connected to the terminal 13 located in the inner cavity 1101, and then the terminal assembly 1 is fixed on the compressor body. The terminal 13 can be quickly and stably connected to the compressor body, and the electrical connection points of the terminal 13 and the connection post 11 are wrapped by the housing 11 to improve the stability of the electrical connection.

[0079] Again, for example, in combination with Figure 4 and Figure 7 , in some embodiments of the present invention, the terminal assembly 1 further includes a temperature sensing component 16, the housing 11 has a mounting groove 1102, the temperature sensing component is positioned in the mounting groove, and the seal 12 includes a second sealing portion 1224 arranged in a ring around the mounting groove 1102. When the terminal assembly 1 is installed on the compressor, the temperature sensing component 16 can be in contact with the outer surface of the compressor body for temperature measurement.

[0080] It is understandable that the seal 12 includes a second seal portion 1224 arranged in a ring around the mounting groove for sealing the gap between the mounting groove 1102 and the compressor body, further achieving a sealing effect.

[0081] Combined Figure 4 with Figure 8 In some other embodiments of the present invention, the temperature sensing terminal 15 is arranged in the cover 11, and the slot 116 is arranged on the cover 11 for electrically connecting the temperature sensing terminal 15 with the temperature sensing component 16. During the assembly process, only the temperature sensing component 16 needs to be inserted into the slot 116 to be electrically connected with the temperature sensing terminal 15. At this time, the temperature sensing component 16 is fixed in the mounting groove 1102 of the cover 11, and then the terminal assembly 1 is fixed on the compressor body, further improving the integration of the terminal assembly 1 and simplifying the assembly process between the terminal assembly 1 and the compressor body, and improving the installation efficiency of the compressor.

[0082] In some other embodiments of the present invention, the temperature sensing component 16 is installed on the cover 11 and has a temperature sensing surface protruding from the cover 11 to the mating surface. After the cover 11 is processed, the temperature sensing component 16 can be pre-installed on the cover 11. When the terminal assembly 1 is connected to the compressor body, the temperature sensing surface of the temperature sensing component 16 contacts the outer surface of the compressor body for temperature measurement.

[0083] The compressor according to the present invention will be briefly described below.

[0084] As Figure 9 and Figure 10 shown, the compressor according to an embodiment of the present invention includes a compressor body 2 and the terminal assembly 1 of the compressor in some of the above embodiments.

[0085] The compressor in the embodiment of the present invention mates the terminal assembly 1 with the compressor body 2 and then locks the terminal assembly 1 to the compressor body 2, simplifying the assembly steps of the compressor. At the same time, the seal 12 seals the gap between the cover 11 and the compressor body 2, and together with the cover 11, isolates external liquid and dust, preventing water vapor, liquid, and dust from entering the cover 11 and causing harmful effects on the functional components 13.

[0086] In some embodiments of the present invention, the bolt 3 locks the terminal assembly 1 to the compressor body 2 through the mounting hole 113.

[0087] The cover and the compressor body in the present invention can be assembled together in different ways. For example, the cover and the compressor body can be welded, interference-fitted, snap-connected, bolt-connected, etc. The assembly method between the cover and the compressor body can be set according to actual needs. Some descriptions of the assembly method between the cover and the compressor body are given in the present invention, but this is not a limitation on the protection scope of the present invention.
