Further, the terminal assembly 10 further comprises a terminal plug-in 12, the terminal plug-in 12 comprises a main body 121 opposite to the socket 102, the main body 121 is provided in the mounting cavity 101, and at least a portion of the main body 121 is provided between the first inner cavity wall 1011 and the second inner cavity wall 1012.

The compressor 100 includes a terminal post 222 for connecting to a power source, and the terminal assembly 10 can be electrically connected to the terminal post 222. When the terminal assembly 10 is connected to the housing 20, the terminal post 222 provided in the housing 20 is pressed into the socket 102, and the terminal post 222 is electrically connected to the terminal plug-in 12 in the first housing 11. During the assembly process, it is only necessary to install the terminal assembly 10 on the housing 20, and then fix the terminal assembly 10 on the housing 20. During the assembly process, the terminal post 222 extends into the first housing 11 through the socket 102, and is electrically connected to the terminal plug-in 12 located in the first housing 11. The terminal plug-in 12 can be quickly and stably connected to the housing 20, and is wrapped in the first housing 11, so as to wrap the electrical connection point between the terminal plug-in 12 and the terminal post 222 through the first housing 11, thereby improving the stability of the electrical connection. The assembly efficiency of the compressor 100 can be improved, and water and electricity isolation at the electrical connection points can be achieved, thereby improving the operational stability of the compressor 100. Under the premise of ensuring the reliability of the compressor 100, the labor cost of assembling the compressor 100 by air conditioner manufacturers can be effectively reduced through the integrated structure.

A plurality of terminal plug-ins 12 can be pre-installed in the first housing 11, and the terminal plug-in 12 is adapted to the first housing 11, and the terminal plug-in 12 is fixed by the first housing 11. Figures 1 to 3 , and combined with Fig.12 and Fig.13When the terminal plug-in 12 is used to connect the power supply, two, three, four or other number of terminals 222 can be set according to the type of the compressor 100, and the terminal plug-in 12 can be set to a plurality corresponding to the terminals 222. The first housing 11 can include a plurality of mounting cavities 101 and a plurality of sockets 102, the plurality of terminal plug-ins 12 correspond to the plurality of mounting cavities 101, the plurality of sockets 102 correspond to the plurality of mounting cavities 101, the terminal plug-in 12 is set in the corresponding mounting cavities 101, and the sockets 102 are connected to the corresponding mounting cavities 101. The plurality of mounting cavities 101 can be set to be connected to each other or separated from each other.

[0041] The first housing 11 is further provided with a first protrusion 1131, at least a portion of which is provided between the main body 121 and the first inner cavity wall 1011 along the first direction AA.

[0042] According to the terminal assembly 10 for the compressor 100 according to the embodiment of the present invention, the first cover shell 11 can be used to protect the terminal plug-in 12, and multiple terminal plug-ins 12 can be arranged in the same first cover shell 11. By positioning the terminal plug-in 12 using the installation cavity 101, the stability of the positioning of the terminal plug-in 12 can be improved, thereby improving the installation efficiency of the terminal assembly 10.

[0043] like Figure 7 and Figure 8 In some embodiments, the minimum distance between the first inner cavity wall 1011 and the second inner cavity wall 1012 along the first direction AA is X1, and the minimum distance between the first protrusion 1131 and the second inner cavity wall 1012 is X2, wherein 0.9≤X2 / X1≤0.97.

[0044] like Fig.14 , showing the relationship between the ratio X2 / X1 and the terminal insertion force ( Fig.14 The dotted line in the figure), and the relationship between the ratio X2 / X1 and the number of cycles ( Fig.14 ). Fig.14 It can be seen that the present invention comprehensively considers the terminal insertion force and the number of cycles by setting the ratio X2 / X1 to be greater than or equal to 0.9 and less than or equal to 0.97, thereby avoiding the problem of a small number of cycles due to a too small ratio X2 / X1, and also avoiding the problem of a large terminal insertion force due to a too large ratio X2 / X1, which can facilitate the installation of the terminal assembly and facilitate the maintenance and replacement of the terminal assembly. Optionally, the ratio X2 / X1 can be set to 0.9, 0.918, 0.94, 0.945, 0.96 or 0.97, etc.

By setting the first protrusion 1131 to an inclined extension shape, the elastic force of the first protrusion 1131 can be enhanced, the effective positioning of the terminal plug-in 12 can be achieved, and the deformation of the terminal plug-in 12 when the terminal post 222 is inserted is facilitated, and the terminal post 222 is convenient for plugging and matching with the terminal plug-in 12.

[0046] like Fig.15 , showing the corresponding relationship between the angle α and the terminal stress ( Fig.15 The dotted line in the figure), and the corresponding relationship between the angle α and the number of cycles ( Fig.15 ). Fig.15 It can be seen that the present invention comprehensively considers the terminal stress and the number of cycles by setting the angle α to be greater than or equal to 20° and less than or equal to 80°, thereby avoiding the problem of a small number of cycles due to a too small angle α; and also avoiding the problem of a large terminal stress due to a too large angle α, which can facilitate the installation of the terminal assembly and facilitate the maintenance and replacement of the terminal assembly. Optionally, the angle α can be set to 20°, 35°, 46°, 58.8°, 68° or 80°, etc.

[0047] Optionally, in a cross section perpendicular to the axis of the socket 102, the first protrusion 1131 has a fixed end and a free end, the fixed end is connected to the first inner cavity wall 1011, and the free end of the first protrusion 1131 is provided with a third protrusion 1133, and the extension direction of the third protrusion 1133 is parallel to the side wall of the main body 121.

[0048] In addition, combined Figure 5 , Fig. 9 , Fig.12 and Fig.13In some embodiments of the present invention, the first housing 11 further includes a second protrusion 1132, at least a portion of which is disposed between the main body 121 and the second inner cavity wall 1012 along the first direction AA. The first protrusion 1131 and the second protrusion 1132 can be used to position the terminal plug-in 12 to improve the positioning stability of the terminal plug-in 12, so that the terminal assembly 10 can be disassembled and assembled from the housing 20 of the compressor 100 for multiple times.

[0049] In some embodiments, the minimum distance between the first inner cavity wall 1011 and the second inner cavity wall 1012 along the first direction AA is X1, and the minimum distance between the first protrusion 1131 and the second protrusion 1132 is X3, wherein 0.75≤X3 / X1≤0.95.

[0050] like Fig.16 , showing the relationship between the ratio X3 / X1 and the terminal insertion force ( Fig.16 The dotted line in the figure), and the relationship between the ratio X3 / X1 and the number of cycles ( Fig.16 ). Fig.16 It can be seen that the present invention comprehensively considers the terminal insertion force and the number of cycles by setting the ratio X3 / X1 to be greater than or equal to 0.7 and less than or equal to 0.95, thereby avoiding the problem of a small number of cycles due to a too small ratio X3 / X1, and also avoiding the problem of a large terminal insertion force due to a too large ratio X3 / X1, which can facilitate the installation of the terminal assembly and facilitate the maintenance and replacement of the terminal assembly. Optionally, the ratio X3 / X1 can be set to 0.7, 0.718, 0.74, 0.845, 0.92 or 0.95, etc.

[0051] Optionally, the minimum distance between the first inner cavity wall 1011 and the second inner cavity wall 1012 along the first direction AA is X1, and the minimum distance between the second protrusion 1132 and the first inner cavity wall 1011 is X4, wherein 0.9≤X4 / X1≤0.97.

[0052] In addition, in some embodiments, the protrusion size of the first protrusion 1131 relative to the first inner cavity wall 1011 is the same as the protrusion size of the second protrusion 1132 relative to the second inner cavity wall 1012. This can provide a stable positioning effect for the main body 121, facilitate the stable matching of the main body 121 and the socket 102, so that the terminal 222 can pass through the socket 102 and extend into the installation cavity 101 to be electrically connected with the main body 121.

[0053] Additionally, in some embodiments, the first protrusion 1131 and the second protrusion 1132 are symmetrical with respect to the main body 121 .

[0054] Among them, combined Figure 5 , Fig. 9, Fig.12 and Fig.13 In some embodiments, in a cross section perpendicular to the axis of the socket 102, the second protrusion 1132 has a fixed end and a free end, the fixed end is connected to the second inner cavity wall 1012, the extension trend from the fixed end to the free end is set as the second protrusion direction line, the extension trend of the second inner cavity wall 1012 along the second direction BB is set as the second inner cavity direction line, the second protrusion direction line and the second inner cavity direction line have an angle greater than zero and less than 180 degrees, and the first direction AA, the second direction BB and the axis of the socket 102 are perpendicular to each other. By setting the second protrusion 1132 to an inclined extension shape, the elastic force of the second protrusion 1132 can be enhanced, the effective positioning of the terminal plug-in 12 can be achieved, and the deformation of the terminal plug-in 12 when the terminal post 222 is inserted is facilitated, and the terminal post 222 is convenient for plugging and matching with the terminal plug-in 12.

[0055] Optionally, the angle β between the second protrusion direction line and the second inner cavity direction line is set to satisfy 20°≤β≤80°.

[0056] Optionally, the present invention comprehensively considers the terminal stress and the number of cycles by setting the angle β to be greater than or equal to 20° and less than or equal to 80°, thereby avoiding the problem of a small number of cycles due to a too small angle β, and avoiding the problem of a large terminal stress due to a too large angle β, which can facilitate the installation of the terminal assembly and facilitate the maintenance and replacement of the terminal assembly. Optionally, the angle β can be set to 20°, 35°, 46°, 58.8°, 68° or 80°, etc.

[0057] Optionally, in a cross section perpendicular to the axis of the socket 102, the second protrusion 1132 has a fixed end and a free end, the fixed end is connected to the second inner cavity wall 1012, and the free end of the second protrusion 1132 is provided with a fourth protrusion, and the extension direction of the fourth protrusion is parallel to the side wall of the main body 121. It is convenient for the fourth protrusion to cooperate with the main body 121 along the first direction AA, so that the second protrusion 1132 can be used to provide a stable pre-tightening force for the main body 121, thereby improving the stability of the terminal assembly 10.

[0058] Optionally, the first housing 11 has a first end surface portion 103 , and the socket 102 passes through the first end surface portion 103 .

The first sheet 1211 and the second sheet 1212 are integrally connected through a transition portion, which can simplify the structure of the main body 121, and a mounting hole 104 is constructed between the first sheet 1211 and the second sheet 1212. Fig.13, and it is also convenient for the terminal 222 to cooperate with the mounting hole 104. In addition, it is also convenient for the first sheet 1211 and the second sheet 1212 to elastically deform after the terminal 222 is inserted, thereby improving the assembly stability between the main body 121 and the terminal 222.

[0060] For example, the first sheet 1211 and the second sheet 1212 are opposite to each other along the first direction AA, one end of the first sheet 1211 and the second sheet 1212 along the second direction BB is connected by a transition portion, and the other end of the first sheet 1211 and the second sheet 1212 along the second direction BB is separated; or, the first sheet 1211 and the second sheet 1212 are opposite to each other along the first direction AA, one end of the first sheet 1211 and the second sheet 1212 along the second direction BB is connected by a transition portion, and the other end of the first sheet 1211 and the second sheet 1212 along the second direction BB is connected by a transition portion, etc. In addition, the terminal plug 12 further includes a wiring portion 122, which can be connected to the main body 121, specifically, the wiring portion 122 can be connected to the first sheet 1211 and / or the second sheet 1212.

The terminal 222 can pass through the socket 102 and extend into the mounting hole 104, and cooperate with the mounting hole 104 to achieve stable assembly of the terminal 222 and the terminal plug. In addition, the mounting hole 104 can be set to a shape in which the size along the first direction AA is smaller than the size along the second direction BB, and the first direction AA, the second direction BB and the axis of the socket 102 are perpendicular to each other. In this way, it is convenient for the size of the mounting hole 104 to change after the terminal 222 is inserted into the mounting hole 104, for example, it is convenient for the size of the mounting hole 104 to increase along the first direction AA and decrease along the second direction BB, so that the terminal plug 12 can be stably matched with the terminal 222 and the conductive performance can be improved.

[0063] In addition, the terminal plug-in 12 further includes a wiring portion 122 , which is connected to the main body 121 and extends along the second direction, so that the terminal plug-in connection harness 13 can be conveniently connected.

[0066] In addition, a gap may be provided between the inner surface of the installation cavity 101 and the terminal plug-in 12, and the gap is used to provide a margin for elastic deformation of the terminal plug-in 12 when the terminal post 222 is pressed in, so as to facilitate the terminal post 222 to be plugged in and electrically connected to the terminal plug-in 12. For example, the terminal plug-in 12 may have a first sheet 1211 and a second sheet 1212, and the first sheet 1211 and the second sheet 1212 are arranged opposite to each other. When the terminal post 222 is pressed in, the terminal post 222 is pressed between the first sheet 1211 and the second sheet 1212, and the first sheet 1211 and / or the second sheet 1212 will be elastically deformed. By providing a gap between the inner surface of the installation cavity 101 and the terminal plug-in 12, a margin can be provided for the deformation of the first sheet 1211 and / or the second sheet 1212, so as to facilitate the stable cooperation between the terminal post 222 and the terminal plug-in 12, and improve the assembly efficiency between the terminal assembly 10 and the terminal post 222.

[0067] The inner shell 111 and the outer shell 112 in the present invention may be formed in various ways. For example, the inner shell 111 may be provided as an integrated structure or a split structure.

[0068] For example, in some embodiments, the inner shell 111 is divided into a first part 1111 and a second part 1112, and the first part 1111 and the second part 1112 are spliced ​​together, wherein after the first part 1111 and the second part 1112 are spliced ​​together, the installation cavity 101 is arranged between the first part 1111 and the second part 1112. Since the first part 1111 and the second part 1112 are in a spliced ​​form, the terminal plug-in 12 can be placed between the first part 1111 and the second part 1112 during the splicing process of the first part 1111 and the second part 1112, thereby facilitating the installation and positioning of the terminal plug-in 12. The first part 1111 and the second part 1112 can be fixedly connected in a variety of ways. For example, the first part 1111 and the second part 1112 can be fixedly connected by a fixing member (such as a bolt, a pin, a rivet, etc.); for another example, the first part 1111 and the second part 1112 can be fixedly connected by welding, bonding, etc.; in addition, after the first part 1111 and the second part 1112 are assembled, the first part 1111 and the second part 1112 can be fixedly connected together by using the shell 112. Of course, the above description is only some embodiments of the present invention, and does not limit the scope of protection of the present invention.

[0069] For another example, in some other embodiments, the inner shell 111 is integrally formed, wherein the inner shell 111 may have a mounting cavity 101, and the terminal plug 12 is mounted in the mounting cavity 101. Integral molding can improve the structural strength of the inner shell 111, increase the service life of the terminal assembly 10, and improve the processing efficiency of the inner shell 111.

[0070] The inner shell 111 of the present invention can be set to injection molding. In combination with the above-mentioned embodiment, the inner shell 111 can be set to a split structure, for example, the inner shell 111 includes a first part 1111 and a second part 1112, wherein the first part 1111 and the second part 1112 are separately injection molded and assembled together; the inner shell 111 can also be set to be integrally injection molded.

[0071] The inner shell 111 and the outer shell 112 in the present invention can be molded separately. For example, after the inner shell 111 is injection molded, the outer shell 112 and the inner shell 111 are injection molded for the second time. In this way, the position of the terminal plug-in 12 can be maintained by the inner shell 111, so as to avoid the displacement of the terminal plug-in 12 during the second injection molding process, and to provide a deformation margin for the terminal plug-in 12, so as to facilitate the docking of the terminal post 222 with the terminal plug-in 12. The waterproof and dustproof properties of the inner shell 111 and the terminal plug-in 12 are ensured by the second injection molding of the outer shell 112, so as to improve the stability of the terminal assembly 10. For another example, the inner shell 111 includes the aforementioned first part 1111 and the second part 1112. After the first part 1111 and the second part 1112 are assembled and the terminal plug-in 12 is positioned, the outer shell 112 is injection molded for the second time outside the inner shell 111. Of course, the inner shell 111 and the outer shell 112 can also be molded separately in other ways. Optionally, the outer shell 112 surrounds the inner shell 111 by injection molding.

[0072] In addition, if Figure 5 The terminal assembly 10 further includes a wiring harness 13, one end of which is electrically connected to the terminal plug-in 12, and the other end of which extends out of the first housing 11 for connecting to an external device.

Among them, a sealing structure can be formed between the wire harness 13 and the shell 112 to improve the waterproof and dustproof effect of the terminal plug-in 12. For example, the shell 112 can be injection molded, and when the shell 112 is injection molded, the wire harness 13 is wrapped and fixed to the shell 112, so that the sealing between the wire harness 13 and the first cover 11 can be improved. The specifications of the wire harness 13 can be selected according to the current size, wherein the conductor cross-section of the wire harness 13 can be set to be not less than 4 square millimeters.

[0073] In combination with the foregoing, the manufacturing method of the terminal assembly 10 of the present invention may include: connecting the terminal plug-in 12 with the wiring harness 13; manufacturing an inner shell 111 having an installation cavity 101, installing the terminal plug-in 12 in the installation cavity 101, and extending the wiring harness 13; positioning the inner shell 111 with the terminal plug-in 12 installed in the mold, and injection molding the outer shell 112 on the outside of the inner shell 111, the outer shell 112 wraps the inner shell 111, the terminal plug-in 12 and a part of the wiring harness 13, and constructing a socket 102 on the outer shell 112 during the injection molding process, and the socket 102 is opposite to the terminal plug-in 12.

[0074] In some embodiments of the present invention, the inner shell 111 is a block made of PBT (i.e., polybutyleneterephthalate) material mixed with a flame retardant; or, the outer shell 112 is a block made of PBT material mixed with a flame retardant. Thus, the flame retardant performance of the first cover 11 can be ensured, and the stability and safety of the terminal assembly 10 can be improved. In addition, the inner shell 111 can also be set as a block made of PVC (i.e., Polyvinyl chloride) material, or a block made of nylon material; the outer shell 112 can also be set as a block made of PVC material, or a block made of nylon material.

The integration of the terminal assembly 10 can be further improved, and the assembly process between the terminal assembly 10 and the housing 20 can be simplified, thereby improving the installation efficiency of the compressor 100. After the terminal assembly 10 is processed, the temperature sensing component can be pre-installed on the terminal assembly 10. When the terminal assembly 10 is connected to the housing 20, the temperature sensing surface of the temperature sensing component is in close contact with the housing 20 to achieve temperature monitoring. The temperature sensing surface of the temperature sensing component can protrude from the mating surface and directly contact the housing 20.
