Modes for Carrying Out the Invention

[0043] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0044] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] As shown in FIG. 1 and FIG. 2 , according to an embodiment of the present application, the integrated terminal 1 for a compressor can be arranged outside the compressor, and includes: a dustproof cover 11 , a temperature sensing component 12 and a connecting harness 13 .

[0046] Specifically, the dust cover 11 has a mating surface 101 and a mounting groove 102. The mounting groove 102 is provided on the mating surface 101, and the mating surface 101 faces the compressor housing. The temperature sensing component 12 is positioned in the mounting groove 102. When the dust cover 11 is installed on the compressor, the mating surface 101 faces the outer surface of the compressor, and the temperature sensing component 12 can detect the temperature of the compressor housing. A portion of the connecting wire harness 13 is located within the dust cover 11 for electrically connecting to the temperature sensing component 12, and another portion extends out of the dust cover 11. A portion of the connecting wire harness 13 is enclosed by the dust cover 11 to form a sealed structure.

[0047] The present application integrates the dustproof cover 11, the temperature sensing component 12 and the connecting harness 13, and integrates the dustproof cover 11, the temperature sensing component 12 and the connecting harness 13 into the integrated terminal 1 through pre-production. The assembly of the integrated terminal 1 can be completed by connecting the compressor integrated terminal 1 to the compressor and locking it, which simplifies the steps of assembling the temperature sensing component to the compressor and reduces the assembly time. At the same time, the dustproof cover 11 is arranged outside the compressor, and a sealing structure is provided to wrap part of the connecting harness 13 to prevent liquid and dust from entering the dustproof cover 11 through the connection between the dustproof cover 11 and the connecting harness 13, thereby achieving waterproof and dustproofing of the temperature sensing component 12 and part of the connecting harness 13 inside the dustproof cover 11. In addition, when the integrated terminal 1 is arranged on the compressor, the mating surface 101 of the dustproof cover 11 is attached to the compressor, and the dustproof 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 harness 13.

[0048] The temperature sensing component in the present application can be used in a variety of ways to detect temperature. The detection surface 1201 of the temperature sensing component 12 can be brought into indirect contact with the surface of the compressor or directly into contact with the surface of the compressor to detect temperature. For example, a heat-conducting structure is provided on the dust cover, and the heat-conducting structure is in contact with the temperature sensing component and the compressor respectively, so that the detection surface 1201 of the temperature sensing component is in indirect contact with the compressor, and the heat of the compressor shell is transferred to the temperature sensing component to detect temperature. For another example, the detection surface 1201 of the temperature sensing component 12 is brought into direct contact with the surface of the compressor, so as to directly detect the outer shell temperature of the compressor. Of course, the temperature sensing component in the present application can also be used in other ways to detect the temperature of the compressor using the temperature sensing component.

[0049] As shown in Figures 3 and 4, in some embodiments of the present application, the detection surface 1201 of the temperature sensing component 12 is exposed from the mating surface 101. It is understood that when the detection surface 1201 of the temperature sensing component 12 is exposed from the mating surface 101, the detection surface 1201 can directly contact the outer surface of the compressor when assembled to the compressor, ensuring that the detection surface 1201 of the temperature sensing component 12 is in full contact with the compressor, further improving the accuracy of the temperature sensing component 12 in detecting the temperature of the compressor casing.

[0050] Furthermore, in order to improve the temperature measurement accuracy of the temperature sensing component 12, the detection surface 1201 (at least a portion) of the temperature sensing component 12 can be protruded from the mating surface 101. When the integrated terminal is installed on the compressor, the temperature sensing surface can stably contact the compressor to improve the temperature detection accuracy of the compressor.

[0051] As shown in FIG5 and FIG6 , in some embodiments of the present application, a waterproof gasket 2 is provided at the mating surface 101 , and the waterproof gasket 2 is used to seal the gap between the dustproof cover 11 and the compressor 4 , and the waterproof gasket 2 is fixedly connected to the main body of the integrated terminal 1 .

[0052] It is understood that the waterproof gasket 2 is connected to the integrated terminal 1, allowing the integrated terminal 1 to be directly assembled on the compressor 4, further simplifying the assembly steps of the compressor 4. At the same time, when the dust cover 11 is mated with the compressor 4, the waterproof gasket 2 is squeezed by the dust cover 11 and the compressor 4 and elastically deforms, contacting the mating surface 101 and filling the gap between the dust cover 11 and the compressor 4, further improving the waterproof and dustproof effect of the integrated terminal 1.

[0053] In order to achieve the connection between the waterproof gasket 2 and the integrated terminal 1, a variety of methods can be used. In conjunction with Figures 7 and 8, the dust cover 11 has a number of matching grooves 1102, and the waterproof gasket 2 is provided with a number of bosses 21, which are embedded and positioned in the matching grooves 1102. It can be understood that the several bosses 21 on the waterproof gasket 2 can be embedded and positioned in the several matching grooves 1102 of the dust 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. Of course, the waterproof gasket 2 can also be installed on the integrated terminal 1 by bonding, snap-on connection, etc.

[0054] In addition, since waterproof gasket 2 is provided at mating surface 101, in order to improve the stability of the contact between mating surface 101 and the compressor surface, in conjunction with Figures 5-6, detection surface 1201 can be configured to protrude from mating surface 101 by a predetermined dimension a. Furthermore, waterproof gasket 2 is provided at mating surface 101, and the waterproof gasket can elastically deform to seal the gap between mating surface 101 and the compressor. Waterproof gasket 2 protrudes from mating surface 101 by a predetermined dimension t. During the installation of the integrated terminal, the waterproof gasket will elastically deform to close the gap between detection surface 1201 and the outer surface of the compressor. To facilitate contact between mating surface 101 and the outer surface of the compressor, predetermined dimensions a and t can be set to: a≤t. Through the above-mentioned arrangement, the detection surface 1201 protrudes from the mating surface 101. When the detection surface 1201 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 a waterproof gasket 2 to seal the gap between the mating surface 101 and the compressor, water vapor, liquid and dust are blocked, thereby further improving the waterproof and dustproof effect of the temperature sensing component 12 and part of the connecting harness 13.

[0055] It can also be understood that the relationship between the predetermined dimension a and the predetermined dimension t is set so that when the detection surface 1201 contacts the compressor, the waterproof gasket 2 is prevented from being unable to seal the mating surface 101 and the compressor due to the predetermined dimension t being smaller than the dimension of the gap. Since the waterproof gasket 2 can undergo elastic deformation when subjected to the pressure applied by the mating surface 101, the actual thickness of the waterproof gasket 2 protruding from the mating surface 101 is less than or equal to the predetermined dimension t. In order to achieve a sealed gap between the mating surface 101 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 1201 contacts the compressor, the waterproof gasket 2 can seal the gap between the dustproof cover 11 and the compressor, further improving the prevention of water vapor, liquid and dust from entering the dustproof cover 11, and ensuring the normal operation of the temperature sensing component 12.

[0056] In conjunction with Figures 1, 15, and 16, the integrated terminal 1 is configured to be bolted and connected to the compressor 4. For example, as shown in Figures 14 to 17, the compressor 4 is provided with a positioning post 41, and the integrated terminal 1 is provided with a positioning hole 103. The positioning post 41 is inserted into the positioning hole 103 and is connected to the positioning post by a bolt to lock the integrated terminal 1. The positioning post and the nut cooperate to form a bolt locking structure. Alternatively, the integrated terminal 1 can be locked directly to the compressor housing by bolting.

[0057] As shown in Figures 15 and 16, the predetermined dimension a and the predetermined dimension t satisfy: a=80*t / N / Hs, where N is the tightening torque of the bolt (in N·m, N is a value excluding units), Hs is the hardness of the waterproof gasket 2 (determined using the JIS standard, Hs is a value excluding units, 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.

[0058] It is understood that the predetermined dimension t of waterproof gasket 2 is greater than the predetermined dimension a, so that when detection surface 1201 contacts compressor 4, waterproof gasket 2 is prevented from being unable to seal mating surface 101 and the compressor due to the predetermined dimension t being less than the gap dimension, thereby further improving the waterproof and dustproof effectiveness of integrated terminal 1. At the same time, a relationship for calculating predetermined dimension a is established based on the predetermined dimension t, ensuring that waterproof gasket 2 seals mating surface 101 and the compressor while detection surface 1201 fully contacts the compressor 4 casing, further improving the accuracy of temperature sensing component 12 in detecting the compressor casing temperature.

[0059] It will also be appreciated that the predetermined dimension a is also affected by the tightening torque N and the hardness Hs of the waterproof gasket 2. The waterproof gasket 2 undergoes elastic deformation under the pressure applied by the mating surface 101. The smaller the hardness Hs of the waterproof gasket 2, the greater the deformation that can occur. Furthermore, when tightening with bolts, the tightening torque N also affects the thickness of the waterproof gasket 2.

[0060] In some embodiments of the present application, 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 will be appreciated that setting a range for the locking torque N and the hardness Hs is helpful in further determining the predetermined dimension a.

[0061] It can be understood that setting the range of the locking torque N and the hardness Hs is helpful to further determine the predetermined size a.

[0062] In some embodiments of the present application, 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; 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. Of course, the above parameters are merely some embodiments of the present application and are not intended to limit the scope of protection of the present application.

[0063] It can be understood that the range setting of the predetermined size a and the predetermined size t is conducive to ensuring the gap between the sealing mating surface 101 of the waterproof gasket 2 and the compressor 4 while the detection surface 1201 fully contacts the compressor 4 casing, further improving the accuracy of the temperature sensing component 12 in detecting the temperature of the compressor 4 casing.

[0064] In some embodiments of the present application, a = 0.4 mm and t = 1.0 mm. It is understood that setting the predetermined dimensions a and t is beneficial for ensuring a gap between the sealing mating surface 101 of the waterproof gasket 2 and the compressor 4 while ensuring that the detection surface 1201 fully contacts the outer casing of the compressor 4, further improving the accuracy of the temperature sensing component 12 in detecting the outer casing temperature of the compressor 4.

[0065] In some embodiments of the present application, in combination with Figures 7, 9 and 10, the integrated terminal 1 also includes: a temperature sensing terminal 14, the temperature sensing terminal 14 is wrapped in the dustproof cover 11, and is opposite to the mounting groove 102 along the normal of the mating surface 101, and a socket 1101 corresponding to the temperature sensing terminal 14 is provided on the inner surface of the mounting groove 102; wherein, the connecting harness 13 is electrically connected to the temperature sensing terminal 14, and the wiring terminal of the temperature sensing component 12 is passed through the socket 1101 and is electrically connected to the temperature sensing terminal 14.

[0066] It is understood that because the temperature-sensing component 12 is positioned in the mounting groove 102 and the temperature-sensing terminal 14 is opposite to the mounting groove 102 along the normal direction of the mating surface 101, the terminal of the temperature-sensing component 12 passes through the socket 1101 corresponding to the temperature-sensing terminal 14 and contacts the temperature-sensing terminal 14. At this time, the connecting harness 13 is electrically connected to the temperature-sensing terminal 14, thereby achieving an electrical connection between the temperature-sensing component 12 and the temperature-sensing terminal 14. The temperature-sensing component 12 is accommodated and fixed in the mounting groove 102, thereby integrating the temperature-sensing component 12 into the integrated terminal 1. At the same time, the temperature-sensing terminal 14 is enclosed in the dustproof cover 11, which 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 achieving waterproof and dustproof protection for the temperature-sensing terminal 14.

[0067] In some embodiments of the present application, as shown in Figures 11 and 12, the dustproof 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 connecting wire harness 13 is passed through the outer layer structure 112, and the installation groove 102 and the socket 1101 are arranged on the outer layer structure 112.

[0068] It is understood that the temperature sensing terminal 14 is disposed in the inner cavity, and the inner layer structure 111 prevents 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 prevent liquid and dust from contacting the temperature sensing terminal 14 and a portion of the connecting wire harness 13, preventing liquid and dust from entering the temperature sensing terminal 14 and causing harmful effects thereon, thereby achieving waterproof and dustproofing of the temperature sensing terminal 14. Simultaneously, in conjunction with FIG7 , the outer layer structure 112 is provided with a mounting groove 102 and a socket 1101. The socket 1101 is used to position the temperature sensing component 12 and insert it through the socket 1101 for electrical connection to the connecting terminal. The temperature sensing component 12 is accommodated and fixed in the mounting groove 102, thereby integrating the temperature sensing component 12 into the integrated terminal 1.

[0069] It can also be understood that the inner cavity ensures that the temperature sensing terminal 14 has appropriate deformation space in the dustproof cover 11 to cooperate with the terminal of the temperature sensing component 12, so that the cooperation with the terminal of the temperature sensing component 12 is more reliable.

[0070] In some embodiments of the present application, as shown in FIG11 , the outer layer structure 112 is injection molded and wraps the inner layer structure 111 , the temperature sensing terminal 14 and at least a portion of the connecting harness 13 during the injection molding process.

[0071] It is 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, allowing the integrated terminal 1 to be pre-produced, further simplifying the assembly steps of the integrated terminal 1. At the same time, the outer layer structure 112 wraps around the inner layer structure 111, the temperature sensing terminal 14, and at least a portion of the connecting wire harness 13, further isolating the temperature sensing terminal 14 and a portion of the connecting wire harness 13 from liquid and dust, preventing liquid and dust from entering the temperature sensing terminal 14 and causing harmful effects, thereby achieving waterproof and dustproofing of the temperature sensing terminal 14.

[0072] As shown in Figure 12, in some other embodiments of the present application, 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 for accommodating the temperature sensing terminal 14.

[0073] 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 inner layer structure 111 is simple to manufacture, ensuring that the temperature sensing terminal 14 has appropriate deformation space in the dustproof cover 11 to cooperate with the terminal of the temperature sensing component 12, and the cooperation with the terminal of the temperature sensing component 12 is more reliable.

[0074] In some other embodiments of the present application, the inner layer structure 111 is integrally formed. It is understood that the integral formation of the inner layer structure 111 is used to shorten the production time of the inner layer structure 111 and improve production efficiency.

[0075] In some embodiments of the present application, as shown in Figures 1 and 13, the integrated terminal 1 also includes: a waterproof hose 15, which is sleeved on the outer surface of the connecting harness 13 and extends along the connecting harness 13, and the waterproof hose 15 extends out of the dustproof cover 11 by a predetermined length; wherein, a portion of the waterproof hose 15 is wrapped in the dustproof cover 11.

[0076] It is understandable that the waterproof hose 15 is used to seal the gap between the connecting harness 13 and the dustproof cover 11 to prevent water vapor, liquid and dust from entering the dustproof cover 11 and causing harmful effects on the connecting terminals, thereby further improving the waterproof and dustproof effect of the integrated terminal 1.

[0077] In other embodiments of the present application, the waterproof hose 15 is sleeved on the outer surface of the connecting harness 13 and extends along the connecting harness 13, and the waterproof hose 15 extends outward of the outer structure 112 by a predetermined length; wherein, a portion of the waterproof hose 15 is wrapped in the injection-molded outer structure 112.

[0078] It can be understood that when the injection mold is pressed to injection-mold the outer layer structure 112 so that the outer layer structure 112 wraps a part of the connecting harness 13, irregular gaps are easily generated at the connection between the outer layer structure 112 and the connecting harness 13. The waterproof hose 15 is sleeved on the outer surface of the connecting harness 13. Since the waterproof hose 15 is more elastic than the connecting harness 13, the outer layer structure 112 is injection-molded. At this time, the injection-molded outer layer structure 112 wraps a part of the waterproof hose 15. 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 connecting harness 13, preventing water vapor, liquid and dust from entering the dustproof cover 11 and causing harmful effects on the connecting terminal, thereby further improving the waterproof and dustproof effect of the integrated terminal 1.

[0079] In other embodiments of the present application, the waterproof hose 15 can be configured to be connected to or integrally formed with the dustproof housing 11. It is understood that the waterproof hose 15 is connected to or integrally formed with the dustproof housing 11, further reducing the gap between the waterproof hose 15 and the dustproof housing 11, thereby improving the waterproof and dustproof effect of the integrated terminal 1.

[0080] According to some embodiments of the present application, as shown in Figure 13, the dustproof cover 11 includes a first shell 113 and a second shell 114, the first shell 113 is provided with a power line terminal, and the second shell 114 is provided with a mounting groove 102; wherein, the first shell 113 and the second shell 114 are a split structure or an integrated structure.

[0081] It is understood that the dust cover 11 comprises multiple housings and multiple components disposed therein. The dust cover 11 prevents liquid and dust from affecting the operation of the power terminals within the first housing 113 and the temperature-sensing component 12 within the second housing 114, further enhancing the waterproof and dustproof properties of the integrated terminal 1.
