Detailed Implementation

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 the present invention, and should not be construed as limiting the present invention.

[0034] Combination Figures 1 to 9 According to an embodiment of the present invention, the terminal assembly 100 is used to connect to the compressor body 200 to achieve a conductive effect, which facilitates electrical connection and maintenance. Specifically, the terminal assembly 100 includes: a first housing 10 and a gasket 30. The first housing 10 has a first positioning structure 11; the gasket 30 includes a sealing portion 31 and a second positioning structure 32 connected to the sealing portion 31. The first positioning structure 11 is connected to the second positioning structure 32. The sealing portion 31 protrudes from the surface of the first housing 10 and is used for sealing between the terminal assembly 100 and the compressor body 200.

[0035] In other words, during application, when the terminal assembly 100 is mounted on the compressor body 200, a gasket 30 is provided between the terminal assembly 100 and the compressor body 200. The sealing part 31 of the gasket 30 can form a seal between the terminal assembly 100 and the compressor body 200, sealing the gap between the terminal assembly 100 and the compressor body 200, improving the waterproof and dustproof effect between the terminal assembly 100 and the compressor body 200, and also improving the stability of assembly. The gasket 30 also includes a second positioning structure 32. The first housing 10 of the terminal assembly 100 includes a first positioning structure 11. The second positioning structure 32 is adapted to connect with the first positioning structure 11, thereby realizing the connection between the gasket 30 and the first housing 10, so that the gasket 30 can be stably connected to the terminal assembly 100. In this way, when the terminal assembly 100 is assembled onto the compressor body 200, the gasket 30 can directly form a seal between the terminal assembly 100 and the compressor body 200, which facilitates assembly.

[0036] In practical applications, combined with Figure 1 and Figure 2 The second positioning structure 32 of the gasket 30 can be connected to the first positioning structure 11 of the first housing 10, thereby allowing the gasket 30 to be installed on the terminal assembly 100, with the sealing portion 31 of the gasket 30 facing the compressor body 200. When the terminal assembly 100 is installed on the compressor body 200, the gasket 30 can form a seal between the terminal assembly 100 and the compressor body 200, closing the assembly gap, thereby achieving waterproof and dustproof effects and improving the structural stability after assembly and the stability during operation.

[0037] According to an embodiment of the present invention, a gasket 30 is provided on the terminal assembly 100. The gasket 30 includes a sealing part 31 for improving the sealing effect and a second positioning structure 32 for connecting the housing. This can realize a sealed connection between the terminal assembly 100 and the compressor body 200 and facilitate assembly.

[0038] Optionally, one or more gaskets 30 can be provided according to actual usage needs. For example, the gaskets 30 can be designed according to the shape of the first housing 10 to improve the sealing effect; alternatively, when the terminal assembly 100 also includes a second housing 20 or a third housing, multiple gaskets 30 can be provided to be installed on the second housing 20 or the third housing respectively. In practical applications, the gaskets 30 can be designed according to the specific structure of the terminal assembly 100, or whether a local structure of the terminal assembly 100 needs to form a seal with the compressor body 200, to improve the sealing effect and simplify the structure. When multiple gaskets 30 are provided and correspond to different housings respectively, a positioning structure can also be provided on the corresponding housing. This positioning structure is adapted to cooperate with the second positioning structure 32 to connect the gaskets 30 to the housing.

[0039] Furthermore, in some embodiments of the present invention, the first positioning structure 11 is a rigid structure, and the second positioning structure 32 is a flexible structure. In application, the flexible structure is connected to the rigid structure. The flexible structure can improve the stability of the connection between the second positioning structure 32 and the first positioning structure 11. The flexible structure can fully contact the rigid structure after connection, which is beneficial for improving stability after connection. It can also achieve a seal at the connection point, thereby further improving the sealing effect. In addition, the flexible structure can reduce the requirements for manufacturing precision and installation precision of the first positioning structure 11, which is beneficial for reducing manufacturing costs and improving assembly efficiency.

[0040] Furthermore, the sealing portion 31 can also be a flexible structure, so that the sealing portion 31 can achieve an elastic seal between the terminal assembly 100 and the compressor body 200, which is beneficial to improving the sealing effect and has lower structural requirements. Specifically, the sealing portion 31 elastically deforms to form a seal between the terminal assembly 100 and the compressor body 200. In this way, when the terminal assembly 100 is assembled onto the compressor body 200, the sealing portion 31 can undergo elastic deformation to achieve a sealing effect.

[0041] Optionally, the sealing part 31 and the second positioning structure 32 can be made of the same material. For example, the gasket 30 can be manufactured as a single piece to facilitate manufacturing and improve the overall structural stability. That is, the entire gasket 30 is a flexible structure, which can simultaneously improve the tightness of the fit and sealing effect of the connecting part and the sealing part.

[0042] Alternatively, the sealing part 31 and the second positioning structure 32 can also be flexible structures with different degrees of flexibility. For example, the sealing part 31 is more flexible than the second positioning structure 32. In this way, the second positioning structure 32 can be a flexible structure with a certain degree of hardness, which can facilitate connection with the rigid first positioning structure 11. The sealing part 31 is more flexible, that is, softer, and can deform after assembly to better seal the assembly gap and improve the sealing effect.

[0043] Combination Figures 4 to 7 In some embodiments of the present invention, the first housing 10 includes a first portion 111 and a second portion 112. The second portion 112 is located inside the first portion 111, and a positioning groove 101 is formed between the first portion 111 and the second portion 112. The positioning groove 101 constitutes a first positioning structure 11. The second positioning structure 32 can be positioned within the positioning groove 101, thereby realizing the connection between the first positioning structure 11 and the second positioning structure 32. The structure is simple and easy to assemble. Specifically, the first portion 111 and the second portion 112 can not only form the positioning groove 101 for connecting the second positioning structure 32, but also improve the overall structural stability of the first housing 10. By setting the positioning groove 101, the second positioning structure 32 can be connected to the first housing 10. The cooperation between the positioning groove 101 and the second positioning structure 32 can also increase the contact area between the second positioning structure 32 and the first housing 10, improve the tightness of the connection, and improve the structural stability after the first positioning structure 11 and the second positioning structure 32 are connected. The structure is simple and easy to assemble.

[0044] Furthermore, combined Figure 3 and Figure 4 The second positioning structure 32 is configured to extend into the positioning groove 101, thereby connecting the gasket 30 to the first housing 10. Specifically, during assembly, the second positioning structure 32 can be directly inserted into or embedded in the positioning groove 101 to connect the gasket 30, which simplifies the structure and facilitates rapid assembly. Figure 4 The second positioning structure 32 can be annular to fit into the positioning groove 101.

[0045] Optionally, the second positioning structure 32 can be configured to be narrower at the top and wider at the bottom. For example, taking the assembly of the second positioning structure 32 in the vertical direction as an example, the size of the upper end (or the end facing the positioning groove 101) of the second positioning structure 32 can be smaller than the size of the positioning groove 101, so that the second positioning structure 32 can be easily inserted into the positioning groove 101; while the size of the middle and lower parts of the second positioning structure 32 can be equal to or slightly larger than the size of the positioning groove 101, so that it can fully cooperate with the positioning groove 101 and improve the stability after assembly.

[0046] Specifically, according to a specific embodiment of the present invention, the terminal assembly 100, in conjunction with Figure 3 and then Figure 4 The second positioning structure 32 is connected to the sealing part 31 along the assembly direction, and both the second positioning structure 32 and the sealing part 31 are annular. The inner diameter of the sealing part 31 is larger than the inner diameter of the second positioning structure 32, and the outer diameter of the sealing part 31 is larger than the outer diameter of the second positioning structure 32. Therefore, when combined... Figure 3 The gasket 30 has a "T" shaped cross-section. During assembly, the smaller second positioning structure 32 first extends into the positioning groove 101. After the second positioning structure 32 extends into the positioning groove 101, the sealing part 31 can seal the positioning groove 101 and cover or enclose the first part 11 of the first housing 10, thereby improving the structural stability after assembly and improving the sealing effect.

[0047] Furthermore, combining Figure 4 In some embodiments of the present invention, the outer peripheral surface of the second part 112 is provided with a first protruding rib 1121, and the second positioning structure 32 elastically deforms to accommodate the first protruding rib 1121, which can increase the stability of the connection between the second positioning structure 32 and the first positioning structure 11.

[0048] Alternatively, the inner circumferential surface of the first part 111 may be provided with a second protruding rib 1111, and the second positioning structure 32 may elastically deform to accommodate the second protruding rib 1111. Alternatively, both a first protruding rib 1121 and a second protruding rib 1111 may be provided, and the second positioning structure 32 may elastically deform to accommodate the first protruding rib 1121 and the second protruding rib 1111, wherein the first protruding rib 1121 on the outer circumferential surface of the second part 112 and the second protruding rib 1111 on the inner circumferential surface of the first part 111 may be staggered or arranged opposite to each other.

[0049] Combination Figure 6 In other embodiments of the invention, the second portion 112 is configured as a multi-segment annular structure extending discontinuously, with a groove 110 formed between adjacent ends. The pad 30 has a protrusion 33 located within the groove 110. That is, the first housing 10 and the pad 30 can be connected and fixed by the protrusion 33 extending into the groove 110. More specifically, the size of the groove 110 can be slightly smaller than the size of the protrusion 33. In conjunction with the foregoing, the second positioning structure 32 can be a flexible structure, thereby allowing the protrusion 33 to deform appropriately to be fixedly engaged within the groove 110, improving the stability after connection.

[0050] Specifically, in combination Figure 6The annular structure constructed by the second part 112 forms a positioning groove 101 with the first part 111. At least a portion of the second positioning structure 32 can extend into the positioning groove 101 to achieve the effect of connection and positioning. The gasket 30 is also provided with a locking protrusion 33, which is located at the locking groove 110, and can further improve the connection effect. More specifically, the locking protrusion 33 can be provided on the second positioning structure 32. The second positioning structure 32 is annular, and the inner peripheral wall of the annulus is provided with the locking protrusion 33. During assembly, the position of the locking protrusion 33 is aligned with the position of the locking groove 110. When the second positioning structure 32 extends into the positioning groove 101, the locking protrusion 33 can be directly located at the locking groove 110. The locking protrusion 33 and the locking groove 110 cooperate to prevent the gasket 30 from moving circumferentially after installation. Figure 6 The second part 112 includes multiple bosses 1125, which extend circumferentially and form a discontinuous, multi-segmented ring. A groove 110 is formed between two adjacent bosses 1125. The bottom surface of the boss 1125 is connected to the first housing 10 and protrudes upward. The boss 1125 is constructed with a shape that gradually widens from the end to the bottom, or in other words, the cross-section of the boss 1125 is trapezoidal, or it is wider at the top and narrower at the bottom. In this way, when the gasket 30 is assembled in the top and bottom direction, it first mates with the narrower end of the boss 1125, thereby making it easier for the second positioning structure 32 to enter the positioning groove 101. The wider bottom of the boss 1125 can then abut against the second positioning structure 32 to improve the tightness of the connection. Alternatively, the size of the positioning groove 101 can be gradually tapering.

[0051] Combination Figures 7 to 9 In some embodiments of the present invention, the second part 112 includes a ring portion 1123 and a protrusion 1124. The protrusion 1124 is connected to the periphery of the ring portion 1123, and the inner wall of the pad 30 is provided with an annular groove 34, into which the protrusion 1124 extends. Thus, a positioning groove 101 can also be constructed between the ring portion 1123 of the second part 112 and the first part 111. The second positioning structure 32 can extend into the positioning groove 101 to achieve initial positioning or connection. The protrusion 1124 can extend into the annular groove 34 of the inner wall of the pad 30, which can further improve the stability after the first positioning structure 11 and the second positioning structure 32 are connected. Specifically, in conjunction with... Figure 8 The first part 111 is located at the open end of the first housing 10, and the annular part 1123 extends out of the opening of the first housing 10. Consequently, the protrusion 1124 also extends out of the opening end. The sealing part 31 is also annular, and an annular groove 34 is located on the inner peripheral wall of the sealing part 31. During assembly, the second positioning structure 32 extends into the positioning groove 101. The outer periphery of the sealing part 31 is connected to the first part 111, and the inner periphery of the sealing part 31 is connected to the second part 112. The annular groove 34 on the inner peripheral wall of the sealing part 31 corresponds to the protrusion 1124, allowing the protrusion 1124 to extend into the annular groove 34.

[0052] Furthermore, the second part 112 may include a plurality of protrusions 1124, which are arranged at intervals along the periphery of the ring 1123, thereby further improving the stability of the connection between the second positioning structure 32 and the first positioning structure 11. Alternatively, the protrusions 1124 may be arranged to surround the periphery of the ring 1123, etc., but the present invention is not limited thereto.

[0053] In some embodiments of the present invention, the first housing 10 and the gasket 30 are interference-fitted, which can improve the stability of the gasket 30 after it is connected to the first housing 10, and help improve the sealing effect. In addition, the interference fit can reduce the assembly difficulty and assembly accuracy, thereby facilitating assembly.

[0054] Combination Figures 2 to 4 In some embodiments of the present invention, the terminal assembly 100 further includes a second housing 20, within which a third positioning structure 23 is provided. The third positioning structure 23 is connected to the second positioning structure 32, and a sealing portion 31 protrudes from the surface of the second housing 20 for sealing between the terminal assembly 100 and the compressor body 200. That is, a gasket 30 can also be installed on the second housing 20 of the terminal assembly 100 to form a seal between the second housing 20 and the compressor body 200. The third positioning structure 23 in the second housing 20 can be the same as the first positioning structure 11 in the first housing 10, and the engagement method between the second positioning structure 32 of the gasket 30 and the third positioning structure 23 of the second housing 20 can refer to one of the aforementioned embodiments, which will not be repeated here.

[0055] It should be noted that the gasket 30 that mates with the first housing 10 and the gasket 30 that mates with the second housing 20 can also have different structures. Specifically, the structure of the positioning structure inside the housing can be set according to the dimensions of the first housing 10 and the second housing 20 for their specific uses. Then, the corresponding gasket 30 can be set according to the specific structure of the positioning structure inside the housing to improve the mating effect between the gasket 30 and the first housing 10 or the second housing 20. During assembly, the gasket 30 with the corresponding structure is installed on the predetermined housing. Thus, the structure of the terminal assembly 100 can be optimized while achieving a seal, and the flexibility of application can be improved.

[0056] Furthermore, the sealing part 31 has a protruding abutment 311 on one end face facing the compressor body 200. The abutment 311 is adapted to be interference fit with the compressor body 200. Thus, when the terminal assembly 100 is installed on the compressor body 200, the abutment 311 can undergo elastic deformation to improve the sealing effect at the connection between the terminal assembly 100 and the compressor body 200.

[0057] Specifically, the terminal assembly 100 may include a first housing 10 and a second housing 20. The first housing 10 may contain wiring terminals, and the second housing 20 may contain a temperature sensor. Thus, the terminal assembly 100 can integrate a power cord and a temperature sensor, improving its integration and functionality. The gasket 30, used for sealing, can be disposed on either the first housing 10 or the second housing 20, providing a seal when both housings are connected to the compressor body 200. This protects the power cord and the temperature sensor, and the seal ensures the temperature sensor operates in a stable environment, improving its detection accuracy. In other words, in the terminal assembly 100 of this application, instead of the first housing 10 and the second housing 20 sharing a single sealing structure, two gaskets 30 are used. This simplifies the structure of the gaskets 30 themselves, reduces assembly difficulty, improves assembly efficiency, and reduces the manufacturing cost of the terminal assembly 100.

[0058] Furthermore, the terminal assembly 100 also includes a connecting part 40, which connects the first housing 10 and the second housing 20. The connecting part 40 is provided with a positioning hole 401, and the terminal assembly 100 can be positioned on the compressor body 200 by passing a fixing screw through the positioning hole 401.

[0059] Combination Figure 4 In some embodiments of the present invention, the outer periphery of the second positioning structure 32 is provided with a mating surface 320, which is adapted to fit against the outer peripheral wall of the connecting portion 40.

[0060] The terminal assembly 100 according to a specific embodiment of the present invention will now be described in conjunction with... Figure 2 The terminal assembly 100 includes a first housing 10, a second housing 20, and a connecting portion 40 connecting the first housing 10 and the second housing 20. The terminal assembly 100 also includes a first gasket 30a connected to the first housing 10 and a second gasket 30b connected to the second housing 20, with identical structures for the first gasket 30a and the second gasket 30b. Thus, when the terminal assembly 100 is mounted on the compressor body 200, a seal is formed between the first housing 10 and the second housing 20 and the compressor body 200, improving the sealing effect. More specifically, in conjunction with... Figure 4 Both the first housing 10 and the second housing 20 include a first part 111 and a second part 112, with a positioning groove 101 formed between the first part 111 and the second part 112. The outer peripheral surface of the second part 112 is provided with a first rib 1121, and the inner peripheral surface of the first part 111 is provided with a second rib 1111. The first rib 1121 and the second rib 1111 are staggered. That is to say, the first positioning structure of the first housing 10 and the second housing 20 can be the same, and the first bushing 30a and the second bushing 20b can also be the same, which can facilitate manufacturing and assembly.

[0061] Combination Figure 2 and Figure 4 In some embodiments of the present invention, the first housing 10 includes an outer shell and a partition 13. A cavity with one open end is formed within the outer shell. A chamber is constructed between the outer shell and the partition 13. A wiring terminal is disposed within the chamber. A second portion 112 is disposed on the partition 13, and a first portion 111 is disposed at the open end of the outer shell. See also... Figure 2 As can be seen, the gasket 30 can cover the open rear end of the housing, thereby forming an isolation between the inside and outside of the housing after the first housing 10 is installed on the compressor body 200, which is beneficial to protect the wiring terminals in the cavity.

[0062] The separator 13 has a socket 103 for pressing in the terminal block of the compressor body 200. When connecting the compressor body 200, the terminal block of the compressor body 200 is pressed into the socket 103, and the terminal block is electrically connected to the terminal block within the first housing 10. During assembly, it is only necessary to install the first housing 10 onto the compressor body 200, with the terminal block extending through the socket 103 into the first housing 10 and electrically connected to the terminal block located within the first housing 10. Then, the terminal assembly 100 is fixed onto the compressor body 200. The terminal block can be quickly and stably connected to the compressor body 200 and is enclosed within the first housing 10. By enclosing the electrical connection point of the terminal block and the terminal block within the first housing 10, the stability of the electrical connection can be improved.

[0063] The terminal assembly 100 of a specific embodiment of the present invention is described below with reference to the accompanying drawings. The terminal assembly 100 can be an injection-molded structure, including an integrally injection-molded first housing 10, a second housing 20, and a connecting portion 40. The terminal assembly 100 also includes a gasket 30, which is a flexible structure. The terminal assembly 100 contains three mating structures: a conductive power line, a temperature sensor for monitoring the compressor temperature, and a three-phase power supply. That is, the terminal assembly 100 is composed of elastic and inelastic components, similar to a sleeve. The upper housing is an inelastic component, injection-molded, integrating components such as the power line and the temperature sensor. The lower gasket 30 is an elastic component, which, when tightened, provides dust and water protection at the mating surface between the housing and the compressor body 200.

[0064] Furthermore, the non-elastic component partially encloses the elastic component, and the two can be fixed together by means of grooves, bosses 1125 or slots.

[0065] The bottom is designed with a raised structure called a stopper 311, which is similar to a skirt. The stopper 311 can deform during installation to enhance waterproof and dustproof capabilities.
