[0043] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0045] As Figure 1 shown, the integrated terminal 1 for a compressor according to an embodiment of the present invention is provided outside the compressor and includes: a dust-proof cover 11, a temperature-sensing component 12, and a connection wire harness 13.

[0046] Specifically, the dust-proof cover 11 has a mating surface and a mounting groove. The mounting groove is provided on the mating surface, and the mating surface faces the housing of the compressor. The temperature sensing component 12 is positioned in the mounting groove. When the dust-proof cover 11 is installed on the compressor, the mating surface faces the outer surface of the compressor, and the temperature sensing component 12 can detect the temperature of the compressor housing. A part of the connecting wire harness 13 is located inside the dust-proof cover 11 for electrically connecting the temperature sensing component 12, and the other part extends out of the dust-proof cover 11. A part of the connecting wire harness 13 is wrapped by the dust-proof cover 11 to form a sealing structure.

[0047] This application integrates the dust-proof cover 11, the temperature sensing component 12, and the connecting wire harness 13. By pre-production, the dust-proof cover 11, the temperature sensing component 12, and the connecting wire harness 13 are integrated into the integrated terminal 1. Connecting the compressor to the integrated terminal 1 and locking it can complete the assembly of the integrated terminal 1, simplifying the steps of assembling the temperature sensing component on the compressor and reducing the assembly time. At the same time, the dust-proof cover 11 is provided outside the compressor and is provided with a sealing structure to wrap a part of the connecting wire harness 13, preventing liquid and dust from entering the dust-proof cover 11 through the connection between the dust-proof cover 11 and the connecting wire harness 13, thereby achieving waterproof and dustproof protection for the temperature sensing component 12 and a part of the connecting wire harness 13 inside the dust-proof cover 11. In addition, when the integrated terminal 1 is provided on the compressor, the mating surface of the dust-proof cover 11 fits against the compressor, and the dust-proof cover blocks external liquid and dust, preventing liquid and dust from entering the integrated terminal 1 and causing harmful effects on the temperature sensing component 12 and the connecting wire harness 13.

[0048] The temperature sensing component in the present invention can detect temperature in various ways. The detection surface of the temperature sensing component 12 can be indirectly in contact with the surface of the compressor or directly in contact with the surface of the compressor for temperature detection. For example, a heat conduction structure is provided on the dust-proof cover, and the heat conduction structure is in contact with the temperature sensing component and the compressor respectively, for the detection surface of the temperature sensing component to be indirectly in contact with the compressor, conducting the heat of the compressor housing to the temperature sensing component for temperature detection; or for example, the detection surface of the temperature sensing component 12 is directly in contact with the surface of the compressor to directly detect the temperature of the outer shell of the compressor. Of course, the temperature sensing component in the present invention can also use other methods to detect the temperature of the compressor using the temperature sensing component.

[0049] According to some embodiments of the present invention, as Figure 2 shown, the detection surface of the temperature sensing component 12 exposes from the mating surface. It can be understood that when the detection surface of the temperature sensing component 12 exposes from the mating surface and is assembled on the compressor, the detection surface can be directly in contact with the outer surface of the compressor, ensuring sufficient contact between the detection surface of the temperature sensing component 12 and the compressor, and further improving the accuracy of the temperature sensing component 12 in detecting the temperature of the compressor housing.

[0050] Furthermore, in order to improve the temperature measurement accuracy of the temperature sensing component 12, the detection surface (at least a part) of the temperature sensing component 12 can be protruded from the mating surface. When the integrated terminal is installed on the compressor, the temperature sensing surface can stably contact the compressor, so as to improve the temperature detection accuracy of the compressor.

[0051] Combined with Figures 2 - 4 , the detection surface can be set to protrude from the mating surface by a predetermined dimension a, and a waterproof gasket 2 is provided at the mating surface. The waterproof gasket can undergo elastic deformation to seal the gap between the mating surface and the compressor. The waterproof gasket 2 protrudes from the mating surface by a predetermined dimension t. During the installation process of the integrated terminal, the waterproof gasket will undergo elastic deformation to facilitate closing the gap between the detection surface and the outer surface of the compressor. In order to facilitate the mating surface to contact the outer surface of the compressor, the predetermined dimension a and the predetermined dimension t can be set as: a ≤ t. Through the above settings, the detection surface protrudes from the mating surface. When the detection surface of the temperature sensing component 12 contacts the compressor, there is a gap between the mating part and the compressor through which water vapor, liquid, and dust can pass. By providing the waterproof gasket 2 to seal the gap between the mating surface and the compressor, water vapor, liquid, and dust are blocked, further improving the waterproof and dustproof effects of the temperature sensing component 12 and part of the connecting wire harness 13.

[0052] It can also be understood that by setting the relationship between the predetermined dimension a and the predetermined dimension t, when the detection surface contacts the compressor, it is avoided that the waterproof gasket 2 cannot seal the mating surface and the compressor due to the predetermined dimension t being smaller than the size of the gap. Since the waterproof gasket 2 can undergo elastic deformation under the pressure applied by the mating surface, the actual thickness of the waterproof gasket 2 protruding from the mating surface is less than or equal to the predetermined dimension t. To seal the gap between the mating surface and the compressor, the predetermined dimension t of the waterproof gasket 2 needs to be greater than or equal to the predetermined dimension a. At this time, when the detection surface contacts the compressor, the waterproof gasket 2 can seal the gap between the dustproof cover 11 and the compressor, further preventing water vapor, liquid, and dust from entering the dustproof cover 11 and ensuring the normal operation of the temperature sensing component 12.

[0053] According to some embodiments of the present invention, combined with Figure 4 and Figure 5 , the integrated terminal 1 is configured to be locked and connected to the compressor 4 by a bolt 3, and the predetermined dimension a and the predetermined dimension t satisfy: a = 80 * t / N / Hs, where N is the locking torque of the bolt 3 (unit: N·m, N is the value without the unit), Hs is the hardness of the waterproof gasket 2 (determined by the JIS standard, Hs is the value without the unit, for example, when the hardness of the waterproof gasket 2 is JIS A30, Hs is 30), and the units of a and t are millimeters.

[0054] It can be understood that the predetermined size t of the waterproof gasket 2 is greater than the predetermined size a. When detecting the surface contact with the compressor 4, it can avoid the situation that the waterproof gasket 2 cannot seal the mating surface and the compressor due to the predetermined size t being smaller than the size of the gap, further improving the waterproof and dustproof effect of the integrated terminal 1. At the same time, a relational expression for calculating the predetermined size a is established based on the predetermined size t, ensuring that while the waterproof gasket 2 seals the mating surface and the compressor, the detection surface fully contacts the housing of the compressor 4, further improving the accuracy of the temperature sensing component 12 in detecting the temperature of the compressor housing.

[0055] It can also be understood that the predetermined size a is also affected by the locking torque N and the hardness Hs of the waterproof gasket 2. The waterproof gasket 2 can undergo elastic deformation under the pressure exerted by the mating surface. The smaller the hardness Hs of the waterproof gasket 2, the greater the deformation that the waterproof gasket 2 can undergo. At the same time, when using the bolt 3 to lock, the locking torque N also affects the thickness of the waterproof gasket 2.

[0056] In some embodiments of the present invention, the locking torque N is not less than 4 and not greater than 6. For example, the locking torque N can be 4, 4.3, 5, or 5.6, etc. The hardness Hs of the waterproof gasket 2 is not less than 25 and not greater than 55. For example, the hardness Hs of the waterproof gasket 2 can be 27, 29, 32, 35, 38, 39, 40, 43, 46, 50, or 51, etc. It can be understood that the range settings of the locking torque N and the hardness Hs are beneficial for further determining the predetermined size a.

[0057] It can be understood that the range settings of the locking torque N and the hardness Hs are beneficial for further determining the predetermined size a.

[0058] In some embodiments of the present invention, a is not less than 0.2 mm and not greater than 0.6 mm. For example, a can be set to 0.21 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.55 mm, or 0.6 mm, etc.; t is not less than 0.5 mm and not greater than 2.0 mm. For example, t can 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, etc. Of course, the above parameters are only some embodiments of the present invention and do not limit the protection scope of the present invention.

[0059] It can be understood that the range settings of the predetermined size a and the predetermined size t are beneficial for ensuring that while the waterproof gasket 2 seals the gap between the mating surface and the compressor 4, the detection surface fully contacts the housing of the compressor 4, further improving the accuracy of the temperature sensing component 12 in detecting the temperature of the compressor 4 housing.

[0060] In some embodiments of the present invention, a = 0.4 mm and t = 1.0 mm. It can be understood that setting the predetermined dimension a and the predetermined dimension t is conducive to ensuring that the detection surface is in full contact with the outer shell of the compressor 4 while ensuring the gap between the sealing mating surface of the waterproof gasket 2 and the compressor 4, and further improving the accuracy of the temperature sensing component 12 in detecting the temperature of the outer shell of the compressor 4.

[0061] In some embodiments of the present invention, in combination with Figure 1 、 Figure 6 and Figure 7 , the integrated terminal 1 further includes: a temperature sensing terminal 14, the temperature sensing terminal 14 is wrapped in the dust-proof cover 11, and is opposite to the installation groove along the normal direction of the mating surface, and a socket 1101 corresponding to the temperature sensing terminal 14 is provided on the inner surface of the installation groove; wherein, the connection wire harness 13 is electrically connected to the temperature sensing terminal 14, and the wiring end of the temperature sensing component 12 passes through the socket 1101 and is electrically connected to the temperature sensing terminal 14.

[0062] It can be understood that since the temperature sensing component 12 is positioned in the installation groove and the temperature sensing terminal 14 is opposite to the installation groove along the normal direction of the mating surface, the wiring end of the temperature sensing component 12 passing through the socket 1101 corresponding to the temperature sensing terminal 14 will contact the temperature sensing terminal 14. At this time, the connection wire harness 13 is electrically connected to the temperature sensing terminal 14, thereby realizing the electrical connection between the temperature sensing component 12 and the temperature sensing terminal 14, and the temperature sensing component 12 is accommodated and fixed in the installation groove, thereby realizing the integration of the temperature sensing component 12 into the integrated terminal 1. At the same time, the temperature sensing terminal 14 is wrapped in the dust-proof cover 11, and the dust-proof cover 11 isolates liquid and dust, preventing liquid and dust from entering the temperature sensing terminal 14 and causing harmful effects on the temperature sensing terminal 14, thereby realizing waterproof and dust-proof for the temperature sensing terminal 14.

[0063] In some embodiments of the present invention, as Figure 8 shown, the dust-proof cover 11 includes an inner layer structure 111 and an outer layer structure 112. The inner layer structure 111 has an inner cavity, the temperature sensing terminal 14 is arranged in the inner cavity, the outer layer structure 112 wraps the inner layer structure 111 and the temperature sensing terminal 14, the connection wire harness 13 passes through the outer layer structure 112, and the installation groove and the socket 1101 are arranged on the outer layer structure 112.

[0064] It can be understood that the temperature sensing terminal 14 is arranged in the inner cavity, and the inner layer structure 111 blocks liquid and dust from contacting the temperature sensing terminal 14; the outer layer structure 112 wraps the inner layer structure 111 and the temperature sensing terminal 14 to further block liquid and dust from contacting the temperature sensing terminal 14 and a part of the connection wire harness 13, preventing liquid and dust from entering the temperature sensing terminal 14 and causing harmful effects on the temperature sensing terminal 14, thereby realizing waterproof and dust-proof for the temperature sensing terminal 14. At the same time, in combination with Figure 7, the outer layer structure 112 is provided with a mounting groove and a socket 1101. The socket 1101 is used to position the temperature sensing component 12 to be inserted through the socket 1101 for electrical connection with the connection terminal. And the temperature sensing component 12 is received and fixed in the mounting groove, so as to integrate the temperature sensing component 12 into the integrated terminal 1.

[0065] It can also be understood that the inner cavity ensures that the temperature sensing terminal 14 has an appropriate deformation space in the dust-proof cover 11 to cooperate with the wiring terminal of the temperature sensing component 12, and the cooperation with the wiring terminal of the temperature sensing component 12 is more reliable.

[0066] In some embodiments of the present invention, such as Figure 9 shown, the outer layer structure 112 is injection molded and wraps at least a part of the inner layer structure 111, the temperature sensing terminal 14 and the connecting wire harness 13 during injection molding.

[0067] It can be understood that the outer layer structure 112 is injection molded to integrate the inner layer structure 111, the temperature sensing terminal 14 and the connecting wire harness 13, and the integrated terminal 1 can be pre-produced, further simplifying the assembly steps of the integrated terminal 1. At the same time, the outer layer structure 112 wraps at least a part of the inner layer structure 111, the temperature sensing terminal 14 and the connecting wire harness 13, further isolating the liquid and dust from contacting a part of the temperature sensing terminal 14 and the connecting wire harness 13, preventing the liquid and dust from entering the temperature sensing terminal 14 and causing harmful effects on the temperature sensing terminal 14, so as to achieve waterproof and dustproof for the temperature sensing terminal 14.

[0068] In other embodiments of the present invention, the inner layer structure 111 includes a first part 1111 and a second part 1112. The first part 1111 and the second part 1112 are spliced and fixedly connected, and an inner cavity is constructed between the first part 1111 and the second part 1112 to accommodate the temperature sensing terminal 14.

[0069] It can be understood that the first part 1111 and the second part 1112 are spliced and fixedly connected to construct an inner cavity for accommodating the temperature sensing terminal 14. The manufacturing method of the inner layer structure 111 is simple, ensuring that the temperature sensing terminal 14 has an appropriate deformation space in the dust-proof cover 11 to cooperate with the wiring terminal of the temperature sensing component 12, and the cooperation with the wiring terminal of the temperature sensing component 12 is more reliable.

[0070] In other embodiments of the present invention, the inner layer structure 111 is integrally formed. It can be understood that the inner layer structure 111 is integrally formed to shorten the production time of the inner layer structure 111 and improve the production efficiency.

[0071] In some embodiments of the present invention, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 11As shown, the integrated terminal 1 further includes: a waterproof hose 15, which is sleeved on the outer surface of the connection wire harness 13 and extends along the connection wire harness 13, and the waterproof hose 15 extends out of the dust-proof cover 11 by a predetermined length; wherein, a part of the waterproof hose 15 is wrapped inside the dust-proof cover 11.

[0072] It can be understood that the waterproof hose 15 is used to seal the gap between the connection wire harness 13 and the dust-proof cover 11, preventing water vapor, liquid, and dust from entering the dust-proof cover 11 and causing harmful effects on the connection terminals, thereby further improving the waterproof and dust-proof effect of the integrated terminal 1.

[0073] In some other embodiments of the present invention, the waterproof hose 15 is sleeved on the outer surface of the connection wire harness 13 and extends along the connection wire harness 13, and the waterproof hose 15 extends out of the outer layer structure 112 by a predetermined length; wherein, a part of the waterproof hose 15 is wrapped inside the injection-molded outer layer structure 112.

[0074] It can be understood that when the injection mold presses and injects the outer layer structure 112 so that the outer layer structure 112 wraps a part of the connection wire harness 13, irregular gaps are likely to occur at the connection between the outer layer structure 112 and the connection wire harness 13. By sleeving the waterproof hose 15 on the outer surface of the connection wire harness 13, since the waterproof hose 15 is more elastic than the connection wire harness 13, when injecting the outer layer structure 112, at this time the outer layer structure 112 wraps a part of the waterproof hose 15, and the waterproof hose 15 undergoes elastic deformation and fits tightly with the outer layer structure 112, thereby reducing the gap at the connection between the outer layer structure 112 and the connection wire harness 13, preventing water vapor, liquid, and dust from entering the dust-proof cover 11 and causing harmful effects on the connection terminals, thereby further improving the waterproof and dust-proof effect of the integrated terminal 1.

[0075] In some other embodiments of the present invention, the waterproof hose 15 can be arranged to be connected to or integrally formed with the dust-proof cover 11. It can be understood that the connection or integral formation of the waterproof hose 15 with the dust-proof cover 11 further reduces the gap between the waterproof hose 15 and the dust-proof cover 11, thereby improving the waterproof and dust-proof effect of the integrated terminal 1.

[0076] In some embodiments of the present invention, as Figure 5 shown, a waterproof gasket 2 is provided at the mating surface for sealing the gap between the dust-proof cover 11 and the compressor 4, and the waterproof gasket 2 is fixedly connected to the main body of the integrated terminal 1.

[0077] It can be understood that the waterproof gasket 2 is connected to the main body of the integrated terminal 1, and the integrated terminal 1 can be directly assembled on the compressor 4, further simplifying the assembly steps of the compressor 4. At the same time, when the dust-proof cover 11 cooperates with the compressor 4, the waterproof gasket 2 is elastically deformed under the extrusion of the dust-proof cover 11 and the compressor 4, contacts the mating surface and fills the gap between the dust-proof cover 11 and the compressor 4, further improving the waterproof and dust-proof effect on the integrated terminal 1.

[0078] According to some embodiments of the present invention, in combination with Figure 6 、 Figure 7 and Figure 10 , the dust-proof cover 11 has a plurality of mating grooves 1102, and a plurality of bosses 21 are provided on the waterproof gasket 2, and the bosses 21 are embedded and positioned in the mating grooves 1102.

[0079] It can be understood that a plurality of bosses 21 on the waterproof gasket 2 can be respectively embedded and positioned in a plurality of mating grooves 1102 of the dust-proof cover 11. At this time, the waterproof gasket 2 is fixedly connected to the main body of the integrated terminal 1, and the integrated terminal 1 can be directly assembled on the compressor 4, further simplifying the assembly steps of the compressor 4.

[0080] According to some embodiments of the present invention, as Figure 11 shown, the dust-proof cover 11 includes a first housing 113 and a second housing 114. A power line terminal is provided in the first housing 113, and an installation groove is provided in the second housing 114; wherein, the first housing 113 and the second housing 114 are of a split structure or an integral structure.

[0081] It can be understood that the dust-proof cover 11 is provided with a plurality of housings and a plurality of components placed in the housings. The dust-proof cover 11 blocks the influence of liquid and dust on the operation of the power terminal in the first housing 113 and the temperature sensing component 12 in the second housing 114, further improving the waterproof and dust-proof effect of the integrated terminal 1. At the same time, the first housing 113 and the second housing 114 are of a split structure or an integral structure, which is convenient for the actual production of the dust-proof cover 11 to be separately manufactured and assembled, or integrally manufactured.

[0082] The compressor assembly according to the present invention will be briefly described below.

[0084] In the compressor assembly according to an embodiment of the present invention, the integrated terminal 1 is fitted with the compressor 4 body, and then the integrated terminal 1 is locked to the compressor, simplifying the assembly steps of the compressor assembly. Meanwhile, the dust-proof cover 11 of the integrated terminal 1 isolates external liquid and dust, preventing water vapor, liquid, and dust from entering the dust-proof cover 11 and causing harmful effects on the temperature-sensing component 12 for monitoring the temperature of the compressor.
