[0045] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0046] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0047] See also Figures 1 to 3 , Figure 1 is a top view schematic diagram of a connector 10 provided in some embodiments of the present application, Figure 2 yes Figure 1 Schematic diagram of the cross section in the AA direction, Figure 3 yes Figure 2 , the connector 10 includes a housing 11 and a connector terminal 12.

[0048] The housing 11 includes a box body 111 and a cover body 112. The box body 111 is formed with a first port 1111 and a second port 1114. The connector terminal 12 is located in the box body 111 via the second port 1114. The connector terminal 12 is used to be electrically connected to the compressor terminal 21 extending into the box body 111 via the first port 1111. The cover body 112 is located on the side of the box body 111 where the second port 1114 is located and covers the second port 1114. The cover body 112 is sealed and connected to the box body 111. The cover body 112 has an external appearance surface 1122. The appearance surface 1122 is a surface that can be observed by the user.

[0049] The housing 11 is designed to include a box body 111 and a cover body 112. The cover body 112 is located on one side of the box body 111 and has an external appearance surface 1122. Compared with the design of a covering cap to wrap the shell and the cover plate, the size of the housing 11 can be reduced to achieve miniaturization of the connector 10. The cover body 112 is sealed with the box body 111, which can prevent impurities such as water vapor and dust from entering the housing 11 through the second port 1114 and affecting the performance of the connector terminal 12. When the compressor 20 uses R290 refrigerant, flammable and explosive refrigerant or combustible refrigerant, the refrigerant can be prevented from entering the connector terminal 12 and the compressor terminal 21, thereby preventing the connector terminal 12 from igniting when the compressor terminal 21 is connected.

[0050] The sealed connection between the cover 112 and the box body 111 can be a sealed connection between the cover 112 and the box body 111 at the periphery of the second port 1114. Furthermore, the cover 112 and the box body 111 can be welded at the periphery of the second port 1114 to achieve close contact between the cover 112 and the box body 111 through material melting to achieve a sealing effect. The welding can be ultrasonic welding, etc. Furthermore, the cover 112 and the box body 111 are welded at the outer edges of the junction between the two, so as to facilitate the welding operation and improve the connection efficiency between the cover 112 and the box body 111.

[0051] The cover 112 and the box body 111 are sealed and connected at the periphery of the second port 1114. A first seal may be provided between the cover 112 and the box body 111 and the first seal may be located at the periphery of the second port 1114, so as to achieve sealing between the two by adding the first seal between the cover 112 and the box body 111. The first seal may be located entirely between the cover 112 and the box body 111, or may be located partially between the cover 112 and the box body 111. If the first seal is partially located between the cover 112 and the box body 111, the remaining portion of the first seal may extend into the cover 112 and / or the box body 111, so as to facilitate the positioning of the first seal between the cover 112 and the box body 111.

[0052] It should be noted that if the cover body 112 and the box body 111 are sealed by the above-mentioned first sealing member, in order to achieve the fixation of the relative position between the cover body 112 and the box body 111 and make the shape of the connector 10 stable, the cover body 112 and the box body 111 will also be connected. For example, the cover body 112 and the box body 111 are snap-connected, welded, or connected by screws and nuts. Among them, the welding connection can be a partial point welding connection at the junction of the cover body 112 and the box body 111, or the above-mentioned outer edge welding connection at the junction of the cover body 112 and the box body 111, and so on. Among them, when the cover body 112 is connected to the box body 111, the first sealing member can be squeezed so that the first sealing member can be in closer contact with the cover body 112 and the box body 111 to achieve a sealing effect.

[0053] One of the cover body 112 and the box body 111 is provided with a limiting protrusion 1124, and the other is provided with a limiting groove 1116 adapted to the limiting protrusion 1124, and the limiting protrusion 1124 is located in the limiting groove 1116. The setting of the limiting protrusion 1124 and the limiting groove 1116 can position the assembly of the cover body 112 and the box body 111, which is conducive to improving the assembly efficiency of the cover body 112 and the box body 111. It can be understood that the limiting protrusion 1124 can be provided on the cover body 112, and the limiting groove 1116 can be provided on the box body 111; or the limiting groove can be provided on the cover body 112, and the limiting protrusion can be provided on the box body 111. In the embodiment of the present application, a limiting protrusion 1124 is provided on the cover body 112, and a limiting groove 1116 is provided on the box body 111. Since the cover body 112 is relatively thin, providing the limiting protrusion 1124 on the cover body 112 is more conducive to improving the structural strength of the cover body 112 than the limiting groove 1116.

[0054] The box body 111 is formed with a first cavity 1117 for accommodating the connector terminal 12 . The first cavity 1117 forms a second port 1114 . The connector terminal 12 is located in the first cavity 1117 via the second port 1114 .

[0055] In some embodiments, the first chamber 1117 may form a first port 1111. In other embodiments, the box body 111 further forms a second chamber 1118, the second chamber 1118 is in communication with the first chamber 1117, the second chamber 1118 is further away from the cover body 112 relative to the first chamber 1117, the side of the second chamber 1118 facing away from the first chamber 1117 forms the first port 1111, and when observed along the first port 1111, the cross-sectional profile of the first chamber 1117 is located within the cross-sectional profile of the second chamber 1118. In this way, when the connector 10 is connected to the compressor 20, the second chamber 1118 is closer to the compressor 20 than the first chamber 1117, and the provision of the second chamber 1118 can reduce the docking area between the connector 10 and the compressor 20, and reduce the precision design requirements of the docking surface of the connector 10.

[0056] See also Figures 4 to 5 , Figure 4 is a schematic front view of a connector 10 provided in some other embodiments of the present application, Figure 5 yes Figure 4 Schematic diagram of the cross section in the BB direction. Figure 6 yes Figure 4 In the bottom view, the connector 10 includes at least two connector terminals 12, the box body 111 is formed with first chambers 1117 equal to the number of the connector terminals 12, each first chamber 1117 has a second port 1114, and each connector terminal 12 is located in each first chamber 1117 via each second port 1114. For example, the connector 10 includes two connector terminals 12, the box body 111 is formed with two first chambers 1117 and two second ports 1114; or, the connector 10 includes three connector terminals 12, the box body 111 is formed with three first chambers 1117 and three second ports 1114.

[0057] If the box body 111 is formed with at least two second ports 1114, the cover body 112 covers all the second ports 1114 and the cover body 112 and the box body 111 are sealed and connected around the periphery of all the second ports 1114. In this way, it is possible to prevent impurities such as water vapor and dust from entering the housing 11 through the second ports 1114 to affect the performance of the connector terminal 12.

[0058] If the cover 112 and the box body 111 are welded, the cover 112 and the box body 111 can be welded at the outer edges of the junction between the cover 112 and the box body 111 to achieve a sealed connection between the cover 112 and the box body 111 at the periphery of all the second ports 1114. If the cover 112 and the box body 111 are sealed by the above-mentioned first sealing member, the first sealing member can be arranged at the periphery of all the second ports 1114, or the number of the first sealing members can be equal to the number of the second ports 1114, and each first sealing member is arranged at the periphery of each second port 1114.

[0059] See also Figure 2 and Figure 3 The connector 10 further includes a connecting wire 14. The housing 11 is formed with a wire hole 113, which is connected to the first chamber 1117. One end of the connecting wire 14 is located in the housing 11 and is electrically connected to the connector terminal 12. The other end of the connecting wire 14 passes through the wire hole 113 and is located outside the housing 11. The connecting wire 14 is used to realize signal interaction between the compressor 20 and the outside world when the connector terminal 12 is connected to the compressor terminal 21.

[0060] The housing 11 is provided with a wire hole 113, which can be formed on the box body 111, or formed on the cover body 112, or formed between the box body 111 and the cover body 112. Figure 2 and Figure 3 If the box body 111 or the cover body 112 is formed with a wire hole 113, the connecting wire 14 needs to be passed through the wire hole 113 before the box body 111 and the cover body 112 are connected. If the housing 11 is formed with a wire hole 113 between the box body 111 and the cover body 112, the connecting wire 14 can be passed through the wire hole 113 before or when the box body 111 and the cover body 112 are connected, and the wire hole 113 is open before the box body 111 and the cover body 112 are connected, which is convenient for placing the connecting wire 14 in the wire hole 113.

[0061] If the housing 11 has a wire hole 113 formed between the box body 111 and the cover body 112, a notch 1115 may be formed on the side of the box body 111 where the second port 1114 is located, and the inner wall of the notch 1115 and the cover body 112 are combined to form the wire hole 113; a notch 1115 may be formed on the side of the cover body 112 close to the box body 111, and the inner wall of the notch 1115 and the box body 111 are combined to form the wire hole 113; or notches 1115 may be formed on both the side of the box body 111 where the second port 1114 is located and the side of the cover body 112 close to the box body 111, and the notches 1115 on both sides are combined to form the wire hole 113.

[0062] Optionally, the box body 111 has a notch 1115 formed on one side where the second port 1114 is located, but no notch 1115 is formed on the cover 112. Since the cover 112 is relatively thin, the notch 1115 is not provided on the cover 112 to ensure the structural strength of the cover 112.

[0063] In the present application, see Figure 2 and Figure 3 The box body 111 is formed with a notch 1115 at one side where the second port 1114 is located, and the notch 1115 is communicated with the first chamber 1117. The cover body 112 is formed with a pressing portion 1123 extending into the notch 1115, and the pressing portion 1123 and the inner wall of the notch 1115 are enclosed to form a wire hole 113. The notch 1115 facilitates the positioning of the connecting wire 14 between the box body 111 and the cover body 112, and the pressing portion 1123 facilitates the connecting wire 14 to be more firmly pressed in the wire hole 113 to prevent the connecting wire 14 from slipping.

[0064] The connecting wire 14 is sealed and connected to the housing 11 at the wire hole 113 to prevent dust, impurities, etc. from entering the housing 11 through the wire hole 113 .

[0065] In an exemplary embodiment, the diameter of the wire hole 113 is smaller than the diameter of the connecting wire 14, and the connecting wire 14 is elastic. In this way, the hole wall of the wire hole 113 squeezes the connecting wire 14, so that the inner wall of the wire hole 113 and the connecting wire 14 are more tightly connected, and a sealing effect can be achieved.

[0066] In another exemplary solution, the connector 10 further includes a second seal 15, which is located in the wire hole 113 and sleeved on the connecting wire 14, and the connecting wire 14 and the housing 11 can be sealed at the wire hole 113 through the second seal 15. The diameter of the wire hole 113 can be larger than the diameter of the connecting wire 14 and smaller than the outer diameter of the second seal 15, so that the second seal 15 can be squeezed by the inner wall of the wire hole 113, and is in close contact with the inner wall of the wire hole 113 and the connecting wire 14, thereby achieving a sealing effect.

[0067] If the cover 112 and the box body 111 are sealed and connected via a first seal located at the periphery of the second port 1114, the first seal and the second seal 15 can be an integral structure or a split structure. In the embodiment of the present application, the first seal and the second seal 15 are an integral structure to save assembly process and improve the sealing performance of the connector 10.

[0068] If the connector 10 includes at least two connector terminals 12 , the number of the connection wires 14 may be equal to the number of the connector terminals 12 , and each connection wire 14 is electrically connected to each connector terminal 12 in a one-to-one correspondence.

[0069] See also Figure 5 If the connector 10 includes at least two connecting wires 14 , the housing 11 may be formed with wire holes 113 , the number of which is equal to the number of the connecting wires 14 , and each connecting wire 14 passes through a corresponding wire hole 113 .

[0070] See also Figure 7 , Figure 7 It is a schematic diagram of the exploded structure of the connector 10 provided in some embodiments of the present application. If the connector 10 includes at least two connecting wires 14, all the connecting wires 14 can be connected as a whole and pass through a wire hole 113 on the housing 11 together.

[0071] The connector 10 further includes a first connector 16, which is connected to one side of the housing 11. The first connector 16 can be used to connect and fix the connector 10 to the compressor 20. Further, the first connector 16 is formed with a connecting hole 163, and the connector 10 and the compressor 20 can be connected and fixed by a second connector 22 extending into the connecting hole 163.

[0072] The connector 10 further includes a third seal 17, at least a portion of which is located on a side of the box body 111 where the first port 1111 is located and is located at the periphery of the first port 1111. The third seal 17 can achieve sealing between the connector 10 and the compressor 20 when the connector 10 is connected to the compressor 20. The portion of the third seal 17 located on the side of the box body 111 where the first port 1111 is located can be compressed when the connector 10 and the compressor 20 are fixed to improve the tightness of the connection between the connector 10 and the compressor 20.

[0073] See also Figure 3 The third sealing member 17 has a sealing surface 173 facing away from the housing 11, and the sealing surface 173 is provided with a material reduction port 1731, and the material reduction port 1731 is arranged around the first port 1111. The provision of the material reduction port 1731 can reduce the mass of the third sealing member 17, so that the compression amount of the third sealing member 17 becomes smaller, so that when the connector 10 is connected to the compressor 20, the rebound force generated when the third sealing member 17 is squeezed will become smaller, so that the side of the third sealing member 17 away from the first connecting member 16 is not easy to rebound and warp, thereby improving the problem of the connector 10 warping on the opposite side fixed to the compressor 20 caused by the unilateral fixation of the connector 10 and the compressor 20, and ensuring the sealing performance of the third sealing member 17 between the connector 10 and the compressor 20.

[0074] Furthermore, the third sealing member 17 has two inclined surfaces 1732 that participate in forming the material reduction port 1731. Both inclined surfaces 1732 are inclined relative to the plugging direction of the connector 10 and the compressor 20, and the distance between the two inclined surfaces 1732 gradually decreases along the direction from the opening of the material reduction port 1731 to the bottom wall. In this way, when the third sealing member 17 is squeezed, the inclination generated by the inclined surface 1732 can be used to make the third sealing member 17 deform as much as possible toward the material reduction port 1731, thereby increasing the deformation amount of the third sealing member 17 and enhancing the sealing performance between the connector 10 and the compressor 20.

[0075] Along the direction from the opening of the material reduction port 1731 to the bottom wall, the distance between the two inclined surfaces 1732 gradually decreases. At this time, the larger distance at the opening of the material reduction port 1731 can accommodate more deformation of the third sealing member 17, while the smaller distance at the bottom wall can constrain the deformed portion of the third sealing member 17. In addition, the deformation of the third sealing member 17 at the two inclined surfaces 1732 is roughly the same, which can improve the flatness of the third sealing member 17 when sealing.

[0076] The third seal 17 also has a connection surface 1733 that participates in forming the material reduction port 1731. The connection surface 1733 is connected between the two inclined surfaces 1732, and the connection surface 1733 is set at an angle with the two inclined surfaces 1732. By setting the connection surface 1733, the connection surface 1733 can be used to increase the distance between the two inclined surfaces 1732 at the bottom wall of the material reduction port 1731, thereby increasing the space for accommodating the deformation of the third seal 17. At this time, the space of the material reduction port 1731 is larger, and the mass of the third seal 17 is smaller, so that the third seal 17 has a smaller rebound force after being squeezed between the connector 10 and the compressor 20, so that when the connector 10 is only connected to the compressor 20 on one side, the third seal 17 is located on the opposite side where the connector 10 and the compressor 20 are fixed, and it is less likely to be lifted.

[0077] It should be noted that the material reduction opening 1731 can be the above-mentioned one including two inclined surfaces 1732, such as a roughly V-shaped material reduction opening; it can also be the above-mentioned one including two inclined surfaces 1732 and a connecting surface 1733, such as a roughly U-shaped material reduction opening, etc. In addition, the material reduction opening 1731 can also adopt other shapes, which is not limited to this.

[0078] It is understandable that the two opposite sides of the third seal 17 can respectively abut the surface of the compressor 20 and the housing 11 of the connector 10 to achieve sealing between the surface of the compressor 20 and the housing 11. In an exemplary solution, the third seal 17 can be provided on the port surface of the housing 11 where the first port 1111 is provided. At this time, in order to achieve a reliable connection between the third seal 17 and the housing 11, the third seal 17 and the housing 11 can be connected by means of adhesives or the like to prevent the third seal 17 from falling off.

[0079] In another exemplary embodiment, the port surface of the first port 1111 of the shell 11 may be provided with an annular groove 1113, and the annular groove 1113 is arranged around the first port 1111. Part of the third seal 17 may be located in the annular groove 1113. The setting of the annular groove 1113 can, on the one hand, locate the installation position of the third seal 17 on the shell 11 and speed up the assembly speed between the third seal 17 and the shell 11; on the other hand, it can restrain the third seal 17 and accommodate the deformation of the third seal 17 caused by extrusion so that it is not easy to move.

[0080] The portion of the third seal 17 located in the annular groove 1113 may be: the third seal 17 includes a first portion 171 and a second portion 172 distributed in the depth direction of the annular groove 1113, the first portion 171 may be located in the annular groove 1113, and the second portion 172 may be located outside the annular groove 1113. The second portion 172 located outside the annular groove 1113 may be deformed when the connector 10 is connected to the compressor 20, so as to improve the tightness of the connection between the connector 10 and the compressor 20.
