DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Combination Figures 1 to 9 The terminal assembly 100 according to the embodiment of the utility model is used to connect the compressor body 200 to achieve the conductive effect, which can facilitate the connection and maintenance of the electrical appliances. 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, and 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] That is to say, when used, the terminal assembly 100 is installed on the compressor body 200, and a gasket 30 is provided between the terminal assembly 100 and the compressor body 200. The sealing portion 31 of the gasket 30 can form a seal between the terminal assembly 100 and the compressor body 200, and can seal the gap between the terminal assembly 100 and the compressor body 200, thereby improving the waterproof and dustproof effect between the terminal assembly 100 and the compressor body 200, and can also improve the stability of assembly. The gasket 30 also includes a second positioning structure 32, and the first housing 10 of the terminal assembly 100 includes a first positioning structure 11. The second positioning structure 32 is suitable for connecting 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 on the compressor body 200, the gasket 30 can directly form a seal between the terminal assembly 100 and the compressor body 200, which is convenient for assembly.

[0036] In practical application, 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 shell 10, so that the gasket 30 can be installed on the terminal assembly 100, and the sealing portion 31 of the gasket 30 faces 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 a waterproof and dustproof effect, and improving the structural stability after assembly and the stability during operation.

[0037] According to the terminal assembly 100 of the embodiment of the utility model, a gasket 30 is arranged on the terminal assembly 100, and the gasket 30 includes a sealing portion 31 for improving the sealing effect and a second positioning structure 32 for connecting the shell, which can realize a sealed connection between the terminal assembly 100 and the compressor body 200 and is easy to assemble.

[0038] Optionally, one or more gaskets 30 can be provided according to actual use needs. For example, the gasket 30 can be provided according to the shape of the first shell 10 to improve the sealing effect. Alternatively, when the terminal assembly 100 also includes a second shell 20 or a third shell, a plurality of gaskets 30 can be provided to be installed correspondingly on the second shell 20 or the third shell. In actual application, how to set the gasket 30 can be determined according to the specific structure of the terminal assembly 100, or whether the local structure of the terminal assembly 100 needs to form a seal with the compressor body 200, so as to improve the sealing effect and simplify the structure. When a plurality of gaskets 30 are provided and correspond to different shells respectively, a positioning structure can also be provided on the corresponding shell, and the positioning structure is suitable for cooperating with the second positioning structure 32 to connect the gasket 30 to the shell.

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

[0040] Furthermore, the sealing portion 31 may also be a flexible structure, so that the sealing portion 31 can achieve elastic sealing between the terminal assembly 100 and the compressor body 200, which is conducive to improving the sealing effect and has low 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 on the compressor body 200, the sealing portion 31 can be elastically deformed to achieve a sealing effect.

[0041] Optionally, the sealing portion 31 and the second positioning structure 32 may be made of the same material, for example, the liner 30 may be manufactured in one piece, which is convenient for manufacturing and can also improve the overall structural stability. That is, the entire liner 30 is a flexible structure, which can simultaneously improve the tightness of the connection part and the sealing part and the sealing effect.

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

[0043] Combination Figures 4 to 7 In some embodiments of the utility model, the first housing 10 includes a first part 111 and a second part 112, the second part 112 is located inside the first part 111, a positioning groove 101 is formed between the first part 111 and the second part 112, and the positioning groove 101 is configured as a first positioning structure 11. The second positioning structure 32 can be positioned in the positioning groove 101, so as to realize the connection between the first positioning structure 11 and the second positioning structure 32, and the structure is simple and easy to assemble. Specifically, the first part 111 and the second part 112 can form the positioning groove 101 for connecting the second positioning structure 32, and can 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, and the positioning groove 101 cooperates with the second positioning structure 32 to 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, and the structure is simple and easy to assemble.

[0044] Furthermore, combined with Figure 3 and Figure 4 The second positioning structure 32 is configured to be suitable for extending into the positioning groove 101, so that the liner 30 can be connected to the first housing 10. Specifically, during assembly, the second positioning structure 32 can be directly inserted or embedded into the positioning groove 101 to achieve the connection of the liner 30, which is conducive to simplifying the structure and facilitating rapid assembly. Figure 4 The second positioning structure 32 may be annular so as to be suitable for extending into the positioning groove 101 .

[0045] Optionally, the second positioning structure 32 can be constructed to be narrow at the top and wide at the bottom. For example, the second positioning structure 32 is assembled from the top and bottom directions. The size of the upper end of the second positioning structure 32 (or the end facing the positioning groove 101) 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; and 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 terminal assembly 100 of a specific embodiment of the present invention, Figure 3 and then Figure 4 The second positioning structure 32 is connected to the sealing part 31 along the assembly direction, and the second positioning structure 32 and the sealing part 31 are both 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, the second positioning structure 32 is connected to the sealing part 31 along the assembly direction, and the second positioning structure 32 and the sealing part 31 are both annular. Figure 3 The cross section of the gasket 30 is a "T"-shaped structure. During assembly, the second positioning structure 32 with a smaller size first extends into the positioning groove 101. After the second positioning structure 32 extends into the positioning groove 101, the sealing portion 31 can block the positioning groove 101 and cover or envelop the first portion 11 of the first shell 10, thereby improving the structural stability after assembly and improving the sealing effect.

[0047] Furthermore, combined with Figure 4 In some embodiments of the present invention, a first rib 1121 is disposed on the outer peripheral surface of the second portion 112 , and the second positioning structure 32 is elastically deformed to accommodate the first 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 circumference of the first portion 111 is provided with a second convex rib 1111, and the second positioning structure 32 is elastically deformed to accommodate the second convex rib 1111. Alternatively, the first convex rib 1121 and the second convex rib 1111 are provided at the same time, and the second positioning structure 32 is elastically deformed to accommodate the first convex rib 1121 and the second convex rib 1111, wherein the first convex rib 1121 on the outer circumference of the second portion 112 and the second convex rib 1111 on the inner circumference of the first portion 111 can be staggered or arranged relative to each other.

[0049] Combination Figure 6 In some other embodiments of the present invention, the second portion 112 is configured as a ring including multiple segments extending intermittently, and a slot 110 is constructed between the two adjacent ends, and the gasket 30 has a protrusion 33, and the protrusion 33 is located in the slot 110. In other words, the first shell 10 and the gasket 30 can be connected and fixed by the protrusion 33 extending into the slot 110. More specifically, the size of the slot 110 can be slightly smaller than the size of the protrusion 33. In combination with the above, the second positioning structure 32 can be a flexible structure, so that the protrusion 33 can be appropriately deformed to be fixedly connected in the slot 110, thereby improving the stability after connection.

[0050] Specifically, combined Figure 6, a positioning groove 101 is formed between the annular structure constructed by the second part 112 and the first part 111, and at least a part of the second positioning structure 32 can extend into the positioning groove 101 to achieve the effect of connection and positioning. A latching protrusion 33 is also provided on the gasket 30, and the latching protrusion 33 is located at the slot 110, which can further improve the connection effect. More specifically, the latching protrusion 33 can be provided on the second positioning structure 32, and the second positioning structure 32 is annular, and the inner peripheral wall of the annular ring is provided with a latching protrusion 33. During assembly, the position of the latching protrusion 33 is opposite to the position of the slot 110. When the second positioning structure 32 extends into the positioning groove 101, the latching protrusion 33 can be directly located at the slot 110. The latching protrusion 33 cooperates with the slot 110 to prevent the gasket 30 from moving in the circumferential direction after installation. Combined with Figure 6 The second part 112 includes a plurality of bosses 1125, which extend in the circumferential direction. The plurality of bosses 1125 form a ring extending discontinuously in multiple sections, and a slot 110 is constructed between two adjacent bosses 1125. The bottom surface of the boss 1125 is connected to the first shell 10 and protrudes upward. The boss 1125 is constructed in a form in which the end gradually expands toward the bottom, or the cross-section of the boss 1125 is trapezoidal, or wide at the top and narrow at the bottom in the up-down direction. In this way, when the gasket 30 is assembled in the up-down direction, it first cooperates with the narrower position of the end of the boss 1125, thereby making it easy for the second positioning structure 32 to enter the positioning groove 101, and the wider position at the bottom of the boss 1125 can abut against the second positioning structure 32 to improve the tightness of the connection. Alternatively, the size of the positioning groove 101 is in a gradually shrinking form.

[0051] Combination Figures 7 to 9 In some other embodiments of the present invention, the second portion 112 includes a ring portion 1123 and a convex portion 1124, the convex portion 1124 is connected to the circumference of the ring portion 1123, and the inner wall of the gasket 30 is provided with an annular groove 34, and the convex portion 1124 extends into the annular groove 34. Therefore, a positioning groove 101 can also be constructed between the ring portion 1123 of the second portion 112 and the first portion 111, and the second positioning structure 32 can extend into the positioning groove 101 to achieve preliminary positioning or connection, and the convex portion 1124 can extend into the annular groove 34 on the inner wall of the gasket 30, which can further improve the stability of the first positioning structure 11 and the second positioning structure 32 after connection. Specifically, combined with Figure 8 The first part 111 is arranged at the opening end of the first housing 10, the ring part 1123 extends out of the opening of the first housing 10, and thus the convex part 1124 also extends out of the opening end, the sealing part 31 is also annular, and the annular groove 34 is arranged 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, wherein the annular groove 34 on the inner peripheral wall of the sealing part 31 corresponds to the convex part 1124, so that the convex part 1124 can extend into the annular groove 34.

[0052] Furthermore, the second portion 112 may include a plurality of convex portions 1124, which are arranged at intervals along the circumference of the ring portion 1123, thereby further improving the stability of the connection between the second positioning structure 32 and the first positioning structure 11. Alternatively, the convex portions 1124 may surround the circumference of the ring portion 1123, and the present invention is not limited thereto.

[0053] In some embodiments of the present invention, the first shell 10 and the gasket 30 are interference fit, which can improve the stability of the gasket 30 after being connected to the first shell 10, which is beneficial to improving 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, a third positioning structure 23 is provided in the second housing 20, 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, and is used for sealing between the terminal assembly 100 and the compressor body 200. In other words, a gasket 30 may also be installed on the second housing 20 of the terminal assembly 100, so as to form a seal between the second housing 20 and the compressor body 200. Among them, the third positioning structure 23 in the second housing 20 may be the same as the first positioning structure 11 in the first housing 10, and the matching method of the second positioning structure 32 of the gasket 30 and the third positioning structure 23 of the second housing 20 may refer to one of the aforementioned embodiments, and will not be repeated here.

[0055] It should be noted that the gasket 30 that matches the first shell 10 and the gasket 30 that matches the second shell 20 may also have different structures. Specifically, the structure of the positioning structure inside the shell can be set according to the dimensions of the specific uses of the first shell 10 and the second shell 20, and then the corresponding gasket 30 can be set according to the specific structure of the positioning structure inside the shell to improve the matching effect of the gasket 30 with the first shell 10 or the second shell 20. During assembly, the gasket 30 with corresponding structure is installed on the predetermined shell. In this way, the structure of the terminal assembly 100 can be optimized while achieving sealing, thereby improving the flexibility during application.

[0056] Furthermore, abutment 311 is convexly provided on the end surface of one side of the sealing portion 31 facing the compressor body 200, and the abutment 311 is suitable for interference fit with the compressor body 200. Therefore, 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 can be provided with a first shell 10 and a second shell 20, wherein a wiring terminal can be provided in the first shell 10, and a temperature sensing part can be provided in the second shell 20, thereby the terminal assembly 100 can integrate the power line and the temperature sensing part to improve the integration effect and functionality of the terminal assembly 100. The gasket 30 for sealing can be configured on the first shell 10 or on the second shell 20, so that when the first shell 10 and the second shell 20 are connected to the compressor body 200, both have a sealing effect, thereby protecting the power line and the temperature sensing part. After sealing, the temperature sensing part can also be ensured to work in a stable environment, thereby improving the detection accuracy of the temperature sensing part. That is to say, on the terminal assembly 100 of the present application, instead of the first shell 10 and the second shell 20 using a common sealing structure, two gaskets 30 are provided, which can not only simplify the structure of the gasket 30 itself, but also reduce the difficulty of assembly, which is conducive to improving assembly efficiency and simplifying the manufacturing cost of the terminal assembly 100.

[0058] Furthermore, the terminal assembly 100 also includes a connecting portion 40, which connects the first shell 10 and the second shell 20. A positioning hole 401 is provided on the connecting portion 40, 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, a mating surface 320 is provided on the outer periphery of the second positioning structure 32 , and the mating surface 320 is suitable for fitting against the outer peripheral wall of the connecting portion 40 .

[0060] The following is an explanation of a terminal assembly 100 according to a specific embodiment of the present invention. Figure 2 The terminal assembly 100 includes a first shell 10 and a second shell 20 and a connecting portion 40 connecting the first shell 10 and the second shell 20. The terminal assembly 100 also includes a first gasket 30a connected to the first shell 10 and a second gasket 30b connected to the second shell 20. The first gasket 30a and the second gasket 30b have the same structure. In this way, when the terminal assembly 100 is installed on the compressor body 200, a seal is formed between the first shell 10 and the second shell 20 and the compressor body 200, which can improve the sealing effect. More specifically, in combination with Figure 4The first housing 10 and the second housing 20 both include a first portion 111 and a second portion 112, a positioning groove 101 is formed between the first portion 111 and the second portion 112, and a first convex rib 1121 is provided on the outer circumference of the second portion 112, and a second convex rib 1111 is provided on the inner circumference of the first portion 111, and the first convex rib 1121 and the second convex rib 1111 are arranged staggered. In other words, the first positioning structures 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 an open end is formed in the outer shell, a chamber is constructed between the outer shell and the partition 13, the connection terminal is arranged in the chamber, the second part 112 is arranged on the partition 13, and the first part 111 is arranged at the open end of the outer shell. Figure 2 It can be seen that the gasket 30 can cover the open rear end of the shell, so as to form isolation inside and outside the shell after the first shell 10 is installed on the compressor body 200, which is beneficial to protect the wiring terminals in the chamber.

[0062] The partition 13 has a socket 103 for pressing into the terminal of the compressor body 200. When the compressor body 200 is connected, the terminal of the compressor body 200 is pressed into the socket 103, and the terminal is electrically connected to the terminal in the first shell 10. During the assembly process, it is only necessary to install the first shell 10 on the compressor body 200, and the terminal extends into the first shell 10 through the socket 103 and is electrically connected to the terminal located in the first shell 10. Then, the terminal assembly 100 is fixed on the compressor body 200. The terminal can be quickly and stably connected to the compressor body 200 and wrapped in the first shell 10, so that the electrical connection point between the terminal and the terminal is wrapped by the first shell 10, which can improve the stability of the electrical connection.

[0063] The following describes a terminal assembly 100 of a specific embodiment of the utility model with reference to the accompanying drawings.
