[0026] The embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference numerals. The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limiting, the present disclosure.

[0027] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] As shown in FIG. 1 and FIG. 2, with an integrated terminal 1 for a compressor according to the embodiments of the present disclosure, the integrated terminal 1 may be disposed outside the compressor. the integrated terminal 1 includes a dust-proof housing 11, a temperature-sensing component 12, and a connection wire harness 13.

[0029] In some embodiments, the dust-proof housing 11 has a fitting surface 101 and a mounting recess 102 formed on the fitting surface 101. The fitting surface 101 is opposite to a shell of the compressor. The temperature-sensing component 12 is positioned in the mounting recess 102. When the dust-proof housing 11 is mounted on the compressor, the fitting surface 101 is opposite to an outer surface of the compressor, and the temperature-sensing component 12 may detect a temperature of the shell of the compressor. A part of the connection wire harness 13 is located in the dust-proof housing 11 to be electrically connected to the temperature-sensing component 12, and another part of the connection wire harness 13 extends out of the dust-proof housing 11. The part of the connection wire harness 13 is wrapped by the dust-proof housing 11 to form a sealing structure.

[0030] In the present disclosure, the dust-proof housing 11, the temperature-sensing component 12, and the connection wire harness 13 are integrated. The dust-proof housing 11, the temperature-sensing component 12, and the connection wire harness 13 are integrated into the integrated terminal 1 through pre-production. Assembly of the integrated terminal 1 may be completed only by connecting the integrated terminal 1 for the compressor to the compressor in a locked manner, which simplifies a step of assembling the temperature-sensing component on the compressor and reduces an assembly time. Meanwhile, the dust-proof housing 11 is disposed outside the compressor, and the sealing structure is formed to wrap a part of the connection wire harness 13, which prevents liquid and dust from entering the dust-proof housing 11 through a connection between the dust-proof housing 11 and the connection wire harness 13. In this way, waterproof and dustproof protection for the temperature-sensing component 12 and the portion of the connection wire harness 13 inside the dust-proof housing 11 is achieved. In addition, when the integrated terminal 1 is disposed on the compressor, the fitting surface 101 of the dust-proof housing 11 is attached to the compressor, and the dust-proof housing blocks external liquid and dust, preventing the liquid and dust from entering the integrated terminal 1 and causing a harmful effect on the temperature-sensing component 12 and the connection wire harness 13.

[0031] The temperature-sensing component in the present disclosure may perform temperature detection in various ways. The sensing surface 1201 of the temperature-sensing component 12 may be in indirect or direct contact with a surface of the compressor for temperature detection. For example, a heat-conducting structure is formed on the dust-proof housing and is in contact with the temperature-sensing component and the compressor, respectively. The heat-conducting structure is used for indirect contact between the sensing surface 1201 of the temperature-sensing component and the compressor, to conduct heat of the shell of the compressor to the temperature-sensing component for temperature detection. For another example, the sensing surface 1201 of the temperature-sensing component 12 is in direct contact with the surface of the compressor to facilitate direct sensing of a temperature of the shell of the compressor. Of course, the temperature-sensing component in the present disclosure may also use other manners to detect a temperature of the compressor by using the temperature-sensing component.

[0032] As shown in FIG. 3 and FIG. 4, in some embodiments of the present disclosure, the temperature-sensing component 12 has a sensing surface 1201 exposed from the fitting surface 101. It can be understood that the sensing surface 1201 of the temperature-sensing component 12 is exposed from the fitting surface 101. When the integrated terminal is assembled on the compressor, the sensing surface 1201 may be in direct contact with the outer surface of the compressor, which ensures sufficient contact between the sensing surface 1201 of the temperature-sensing component 12 and the compressor, and further improves accuracy of the temperature-sensing component 12 in detecting the temperature of the shell of the compressor.

[0033] Further, in order to improve temperature measurement accuracy of the temperature-sensing component 12, (at least a part of) the sensing surface 1201 of the temperature-sensing component 12 may protrude from the fitting surface 101. When the integrated terminal is mounted on the compressor, the temperature-sensing surface may stably be in contact with the compressor, to improve the temperature sensing accuracy of the compressor.

[0034] As shown in FIG. 5 and FIG. 6, in some embodiments of the present disclosure, a water-proof gasket 2 is disposed at the fitting surface 101 to seal a gap between the dust-proof housing 11 and the compressor 4, and the water-proof gasket 2 is fixedly connected to a body of the integrated terminal 1.

[0035] It can be understood that the water-proof gasket 2 is connected to the integrated terminal 1, and the integrated terminal 1 may be directly assembled on the compressor 4, further simplifying the assembly step of the compressor 4. Meanwhile, when the dust-proof housing 11 is mated with the compressor 4, the water-proof gasket 2 undergoes elastic deformation under compression of the dust-proof housing 11 and the compressor 4, is in contact with the fitting surface 101, and fills the gap between the dust-proof housing 11 and the compressor 4. In this way, a waterproof and dustproof protection effect on the integrated terminal 1 is further improved.

[0036] Various manners may be used to realize a connection between the water-proof gasket 2 and the integrated terminal 1. As shown in FIG. 7 and FIG. 8, the dust-proof housing 11 has several engagement grooves 1102, and the water-proof gasket 2 is provided with several protrusions embedded and positioned in the several engagement grooves 1102. It can be understood that the several protrusions 21 on the water-proof gasket 2 may be embedded and positioned in the several engagement grooves 1102 of the dust-proof housing 11. At this time, the water-proof gasket 2 is fixedly connected to the body of the integrated terminal 1, and the integrated terminal 1 may be directly assembled on the compressor 4, further simplifying the assembly step of the compressor 4. Of course, the water-proof gasket 2 may also be mounted on the integrated terminal 1 by means of bonding, a snap connection, or the like.

[0037] In addition, since the water-proof gasket 2 is disposed at the fitting surface 101, in order to improve stability of contact between the fitting surface 101 and the compressor surface, as shown in FIG. 5 and FIG. 6, the sensing surface 1201 may be configured to protrude from the fitting surface 101 by a predetermined dimension a, and the water-proof gasket 2 is disposed at the fitting surface 101 and may undergo elastic deformation to seal a gap between the fitting surface 101 and the compressor. The water-proof gasket 2 protrudes from the fitting surface 101 by a predetermined dimension t. During the mounting of the integrated terminal, the water-proof gasket will undergo elastic deformation to facilitate sealing of a gap between the sensing surface 1201 and the outer surface of the compressor. In order to facilitate the contact of the fitting surface 101 with the outer surface of the compressor, the predetermined dimension a and the predetermined dimension t may be set to satisfy: a≤t. With the above configuration, the detection surface 1201 protrudes from the fitting surface 101. When the detection surface 1201 of the temperature-sensing component 12 is in contact with the compressor, a gap that allows for the passage of water vapor, liquid, and dust exists between the fitting position and the compressor. The water-proof gasket 2 is provided to seal the gap between the fitting surface 101 and the compressor, which blocks the water vapor, liquid, and dust, and further improves a waterproof and dustproof protection effect on the temperature-sensing component 12 and a part of the connection wire harness 13.

[0038] It can also be understood that a relationship between the predetermined dimension a and predetermined dimension t is set to prevent the water-proof gasket 2 from failing to seal the gap between the fitting surface 101 and the compressor due to the predetermined dimension t being smaller than a gap size when the detection surface 1201 is in contact with the compressor. Since the water-proof gasket 2 may undergo elastic deformation under pressure exerted by the fitting surface 101, an actual thickness of the water-proof gasket 2 protruding from the fitting surface 101 is smaller than or equal to the predetermined dimension t. In order to seal the gap between the fitting surface 101 and the compressor, the predetermined dimension t of the water-proof gasket 2 is required to be greater than or equal to the predetermined dimension a. At this time, when the detection surface 1201 is in contact with the compressor, the water-proof gasket 2 may seal the gap between the dust-proof housing 11 and the compressor, to further prevent the water vapor, liquid, and dust from entering the dust-proof housing 11 and ensure normal operation of the temperature-sensing component 12.

[0039] In combination with FIG. 1, FIG. 15, and FIG. 16, the integrated terminal 1 is configured to be connected to the compressor 4 through bolt fastening. For example, as shown in FIG. 14 to FIG. 17, the compressor 4 is provided with a positioning post 41, and the integrated terminal 1 has a positioning hole 103. The positioning post 41 passes through the positioning hole 103, and the integrated terminal 1 is locked by connecting the positioning post with the bolt. The positioning post and a nut cooperate to form a bolt-locking structure. In addition, the locking of the integrated terminal 1 may be realized by directly connecting the bolt to the shell of the compressor.

[0040] As shown in FIG. 15 and FIG. 16, the predetermined dimension a and the predetermined dimension t satisfy: a=80*t / N / Hs, where N is a fastening torque of the bolt (unit: N·m; and N represents a numerical value excluding the unit), and Hs is a hardness of the water-proof gasket 2 (that is determined in accordance with JIS standards; Hs represents a numerical value excluding the unit; and for example, when the hardness of the water-proof gasket 2 is JIS A30, Hs is 30).

[0041] It can be understood that when the predetermined dimension t of the water-proof gasket 2 is set to be greater than the predetermined dimension a, and the detection surface 1201 is in contact with the compressor 4, the water-proof gasket 2 is prevented from failing to seal the gap between the fitting surface 101 and the compressor due to the predetermined dimension t being smaller than the gap size, further improving the waterproof and dustproof protection effect of the integrated terminal 1. Meanwhile, by establishing a formula for calculating the predetermined dimension a based on the predetermined dimension t, it is ensured that the water-proof gasket 2 seals the gap between the fitting surface 101 and the compressor while the detection surface 1201 is in sufficient contact with the shell of the compressor 4, further improving the accuracy of the temperature-sensing component 12 in detecting the temperature of the shell of the compressor 4.

[0042] It can also be understood that the predetermined dimension a is further affected by the fastening torque N and the hardness Hs of the water-proof gasket 2. The water-proof gasket 2 may undergo elastic deformation under the pressure exerted by the fitting surface 101. The lower the hardness Hs of the water-proof gasket 2, the greater deformability of the water-proof gasket 2. Meanwhile, the fastening torque N during the bolt locking also affects the thickness of the water-proof gasket 2.

[0043] In some embodiments of the present disclosure, the fastening torque N is greater than or equal to 4 and smaller than or equal to 6. For example, the fastening torque N may be 4, 4.3, 5, or 5.6, and the hardness Hs of the water-proof gasket 2 is greater than or equal to 25 and smaller than or equal to 55. For example, the hardness Hs of the water-proof gasket 2 may be 27, 29, 32, 35, 38, 39, 40, 43, 46, 50, or 51. It can be understood that range settings of the fastening torque N and the hardness Hs are beneficial to further determination of the predetermined dimension a.

[0044] It can be understood that the range settings of the fastening torque N and the hardness Hs is beneficial to the further determination of the predetermined dimension a.

[0045] In some embodiments of the present disclosure, the predetermined dimension a is greater than or equal to 0.2 mm and smaller than or equal to 0.6 mm. For example, the predetermined dimension a may be set to 0.21 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.55 mm, or 0.6 mm. The predetermined dimension t is greater than or equal to 0.5 mm and smaller than or equal to 2.0 mm. For example, the predetermined dimension t may be set to 0.55 mm, 0.6 mm, 0.8 mm, 1.2 mm, 1.4 mm, 1.6 mm, or 1.8 mm. Of course, the above parameters are merely some implementations of the present disclosure and do not limit the protection scope of the present disclosure.

[0046] It can be understood that the range settings of the predetermined dimension a and predetermined dimension t are beneficial to ensure that the water-proof gasket 2 seals the gap between the fitting surface 101 and the compressor 4 while the detection surface 1201 is in sufficient contact with the shell of the compressor 4, further improving the accuracy of the temperature-sensing component 12 in detecting the temperature of the shell of the compressor 4.

[0047] In some embodiments of the present disclosure, a is equal to 0.4 mm, and t is equal to 1.0 mm. It can be understood that by setting the predetermined dimension a and predetermined dimension t, it is beneficial to ensure that the water-proof gasket 2 seals the gap between the fitting surface 101 and the compressor 4 while the detection surface 1201 is in sufficient contact with the shell of the compressor 4, further improving the accuracy of the temperature-sensing component 12 in detecting the temperature of the shell of the compressor 4.

[0048] In some embodiments of the present disclosure, in combination with FIG. 7, FIG. 9, and FIG. 10, the integrated terminal 1 further includes a temperature-sensing terminal 14 wrapped in the dust-proof housing 11. The temperature-sensing terminal 14 is opposite to the mounting recess 102 in a normal direction of the fitting surface 101. The mounting recess 102 has a socket 1101 formed at an inner surface of the mounting recess 102. The socket 1101 corresponds to the temperature-sensing terminal 14. The connection wire harness 13 is electrically connected to the temperature-sensing terminal 14. The temperature-sensing component 12 has a terminal passing through the socket 1101. The terminal of the temperature-sensing component 12 is electrically connected to the temperature-sensing terminal 14.

[0049] It can be understood that since the temperature-sensing component 12 is positioned in the mounting recess 102 and the temperature-sensing terminal 14 is opposite to the mounting recess 102 in the normal direction of the fitting surface 101, the terminal of the temperature-sensing component 12 is in contact with the temperature-sensing terminal 14 when passing through the socket 1101 corresponding to the temperature-sensing terminal 14. At this time, the connection wire harness 13 is electrically connected to the temperature-sensing terminal 14, realizing an electrical connection between the temperature-sensing component 12 and the temperature-sensing terminal 14. Moreover, the temperature-sensing component 12 is received and fixed in the mounting recess 102, realizing the integration of the temperature-sensing component 12 into the integrated terminal 1. Meanwhile, the temperature-sensing terminal 14 is wrapped within the dust-proof housing 11, and the dust-proof housing 11 isolates the liquid and dust, to prevent the liquid and dust from entering the temperature-sensing terminal 14 and causing a harmful effect on the temperature-sensing terminal 14. In this way, the waterproof and dustproof protection for the temperature-sensing terminal 14 is achieved.

[0050] In some embodiments of the present disclosure, as shown in FIG. 11 and FIG. 12, the dust-proof housing 11 includes an inner layer structure 111 having an inner cavity, and an outer layer structure 112. The temperature-sensing terminal 14 is disposed in the inner cavity. The inner layer structure 111 and the temperature-sensing terminal 14 is wrapped by the outer layer structure 112. The connection wire harness 13 extends through the outer layer structure 112. The mounting recess 102 and the socket 1101 are disposed at the outer layer structure 112.

[0051] It can be understood that the temperature-sensing terminal 14 is disposed in the inner cavity, and the inner layer structure 111 blocks the liquid and dust from being in contact with the temperature-sensing terminal 14. The inner layer structure 111 and the temperature-sensing terminal 14 are wrapped by the outer layer structure 112 to further block the liquid and dust from being in contact with the temperature-sensing terminal 14 and the portion of the connection wire harness 13, which prevents the liquid and dust from entering the temperature-sensing terminal 14 and causing a harmful effect on the temperature-sensing terminal 14. In this way, the waterproof and dustproof protection for the temperature-sensing terminal 14 is achieved. Meanwhile, in combination with FIG. 7, the outer layer structure 112 has the mounting recess 102 and the socket 1101. The socket 1101 is used for positioning the temperature-sensing component 12 that passes through the socket 1101 and is electrically connected to a connection terminal. Moreover, the temperature-sensing component 12 is received and fixed in the mounting recess 102. In this way, it is realized that the temperature-sensing component 12 is integrated into the integrated terminal 1.

[0052] It can also be understood that through the inner cavity, an appropriate deformation space is ensured for the temperature-sensing terminal 14 to mate with the terminal of the temperature-sensing component 12 within the dust-proof housing 11, ensuring a more reliable fitting between the temperature-sensing terminal 14 and the terminal of the temperature-sensing component 12.

[0053] In some embodiments of the present disclosure, as shown in FIG. 11, the outer layer structure 112 is formed by injection molding, and the inner layer structure 111, the temperature-sensing terminal 14, and the part of the connection wire harness 13 is wrapped by the outer layer structure 112 during the injection molding.

[0054] It can be understood that the outer layer structure 112 is formed by injection molding, integrating the inner layer structure 111, the temperature-sensing terminal 14, and the connection wire harness 13 therein, which allows the integrated terminal 1 to be pre-produced, further simplifying the assembly step of the integrated terminal 1. Meanwhile, the inner layer structure 111, the temperature-sensing terminal 14, and the part of the connection wire harness 13 are wrapped by the outer layer structure 112, to further block the liquid and dust from being in contact with the temperature-sensing terminal 14 and a part of the connection wire harness 13, and prevent the liquid and dust from entering the temperature-sensing terminal 14 and causing a harmful effect on the temperature-sensing terminal 14. In this way, the waterproof and dustproof protection for the temperature-sensing terminal 14 is achieved.

[0055] As shown in FIG. 12, in other embodiments of the present disclosure, the inner layer structure 111 includes a first portion 1111 and a second portion 1112. The first portion 1111 and the second portion 1112 are spliced and fixedly connected to each other. An inner cavity is defined between the first portion 1111 and the second portion 1112 to receive the temperature-sensing terminal 14.

[0056] It can be understood that the first portion 1111 and the second portion 1112 are spliced and fixedly connected to form the inner cavity for receiving the temperature-sensing terminal 14. This manufacturing manner of the inner layer structure 111 is simple, ensuring that the temperature-sensing terminal 14 has an appropriate deformation space in the dust-proof housing 11 to mate with the terminal of the temperature-sensing component 12, resulting in a more reliable fitting between the temperature-sensing terminal 14 and the terminal of the temperature-sensing component 12.

[0057] In other embodiments of the present disclosure, the inner layer structure 111 is integrally formed. It can be understood that the integral forming of the inner layer structure 111 is used to shorten a production time of the inner layer structure 111 and improve production efficiency.

[0058] In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 13, the integrated terminal 1 further includes a water-proof hose 15 sleeved on an outer surface of the connection wire harness 13 and extending along the connection wire harness 13. The water-proof hose 15 extends out of the dust-proof housing 11 by a predetermined length. The water-proof hose 15 is partially wrapped in the dust-proof housing 11.

[0059] It can be understood that the water-proof hose 15 is used for sealing a gap between the connection wire harness 13 and the dust-proof housing 11, which prevents the water vapor, liquid, and dust from entering the dust-proof housing 11 and causing a harmful effect on the connection terminal, further improving the waterproof and dustproof protection effect of the integrated terminal 1.

[0060] In other embodiments of the present disclosure, the water-proof hose 15 is sleeved on the outer surface of the connection wire harness 13 and extends along the connection wire harness 13. The water-proof hose 15 extends out of the outer layer structure 112 by the predetermined length. The water-proof hose 15 is partially wrapped in the outer layer structure 112 that is formed by injection molding.

[0061] It can be understood that when an injection mold is closed to form the outer layer structure 112 by injection molding, allowing a part of the connection wire harness 13 to be wrapped by the outer layer structure 112, an irregular gap is likely to be formed at a connection between the outer layer structure 112 and the connection wire harness 13. By sleeving the water-proof hose 15 on the outer surface of the connection wire harness 13, since the water-proof hose 15 is more elastic than the connection wire harness 13, the outer layer structure 112 is formed by injection molding. At this time, the outer layer structure 112 is formed by injection molding to allow the water-proof hose 15 to be partially wrapped therein, and the water-proof hose 15 undergoes elastic deformation and fits tightly with the outer layer structure 112, which reduces a gap at the connection between the outer layer structure 112 and the connection wire harness 13, and prevents the water vapor, liquid, and dust from entering the dust-proof housing 11 and causing a harmful effect on the connection terminal, thus further improving the waterproof and dustproof protection effect of the integrated terminal 1.

[0062] In other embodiments of the present disclosure, the water-proof hose 15 and the dust-proof housing 11 may be connected or integrally formed. It can be understood that the water-proof hose 15 and the dust-proof housing 11 are connected or integrally formed, which further reduces a gap between the water-proof hose 15 and the dust-proof housing 11, improving the waterproof and dustproof protection effect of the integrated terminal 1.

[0063] According to some embodiments of the present disclosure, as shown in FIG. 13, the dust-proof housing 11 includes a first housing 113 and a second housing 114. The first housing 113 is internally provided with a power line terminal, and the mounting recess 102 is formed in the second housing 114. The first housing 113 and the second housing 114 are separately formed or integrally formed.

[0064] It can be understood that the dust-proof housing 11 is provided with a plurality of housings and a plurality of components placed in the housings. The dust-proof housing 11 blocks the liquid and dust from affecting operation of a power terminal in the first housing 113 and operation of the temperature-sensing component 12 in the second housing 114, further improving the waterproof and dustproof protection effect of the integrated terminal 1. Meanwhile, the first housing 113 and the second housing 114 are separately formed or integrally formed, which facilitates actual production of the dust-proof housing 11 by manufacturing and assembling separately or by manufacturing integrally.

Meanwhile, the dust-proof housing 11 of the integrated terminal 1 isolates external liquid and dust, preventing water vapor, liquid, and dust from entering the dust-proof housing 11 and causing a harmful effect on the temperature-sensing component 12 that monitors the temperature of the compressor.
