Description

TECHNICAL FIELD

[0001] The utility model relates to the compressor field especially is related to a thermistor mounting structure, compressor and air conditioner. BACKGROUND

[0002] The exhaust temperature monitoring is the key link of ensuring the normal operation of the compressor. The traditional method is to set the thermistor at the elbow of the compressor exhaust pipe, and the temperature at the place is monitored to indirectly reflect the operating temperature of the compressor. However, when the refrigerant flow is small or there is no refrigerant flow, the temperature of the compressor itself and the temperature at the elbow of the exhaust pipe are significantly different, which causes the temperature monitored by the thermistor to be unable to accurately reflect the actual temperature of the compressor, which may cause the compressor to operate at high temperature, and further cause high-temperature demagnetization and wear.

[0003] To solve the temperature monitoring problem, the prior art uses a fixed bracket welded on the compressor upper cover to install the thermistor. Although this scheme can directly monitor the temperature of the compressor, the welding method has the problems of high cost and difficult to guarantee the welding quality. The material thickness and welding process of the fixed bracket will directly affect the firmness of the welding and the fixing effect of the thermistor. Another scheme is to set a fixed part on the terminal post cover to fix the thermistor. Although this scheme has low cost, the fixed part and the thermistor have hard contact without elastic space, which causes the cover to vibrate slightly and loosen and shift during the operation of the compressor. This loosening and shifting will further cause the position of the thermistor to change, thereby affecting the detection accuracy. SUMMARY

[0016] Optionally, the pressing plate is provided with a window penetrating upward and downward corresponding to the elastic tongue.

[0017] Optionally, the number of the elastic tongues is multiple, and the multiple elastic tongues are arranged at intervals along the insertion direction of the thermistor.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0040] The utility model embodiment provides a thermistor mounting structure first. Figure 1 It is the schematic structural drawing of the thermistor mounting structure according to one embodiment of the utility model, Figure 2 It is the schematic structural drawing of the terminal post cover 200 according to one embodiment of the utility model, Figure 3 It is the schematic plan view of the thermistor mounting structure according to one embodiment of the utility model, Figure 4 It is Figure 3 The schematic sectional view along A-A direction in, Figure 5 It is Figure 3 The schematic sectional view along B-B direction in. As Figures 1 to 5 Indicated, the thermistor mounting structure can generally include terminal post cover 200 and at least one elastic tongue 241.

[0041] Terminal post cover 200 is mainly used to cover and protect the terminal post of compressor, prevents dust, moisture and other pollutants from entering the terminal post area, to ensure the safety and reliability of electrical connection. Terminal post cover 200 can be buckled on compressor top cover 100, and is fixed with compressor top cover 100 by screwing or clamping and the like. Terminal post cover 200 has the mounting groove 230 with the notch downwards, and one end of the mounting groove 230 is formed with the mounting port 231 for the thermistor 300 to insert.

[0042] At least one elastic tongue 241 gradually extends inward from the top of the mounting groove 230 along the insertion direction of the thermistor 300, and is configured to be gradually extruded outward during the insertion of the thermistor 300, so as to use the elastic force of itself to abut the thermistor 300 against the compressor top cover 100, and limit the thermistor 300 from being pulled out of the mounting groove 230.

[0043] With the above scheme, the terminal cover 200 has a mounting slot 230 with a notch facing downward, and when the terminal cover 200 is buckled on the compressor top cover 100, the mounting slot 230 can partially expose the compressor top cover 100. The thermistor 300 can be simply pushed into the mounting slot 230 from the mounting opening 231 to realize contact with the compressor top cover 100, so that the compressor temperature can be easily detected, and the installation steps are simplified. At the same time, the mounting slot 230 is equipped with at least one elastic tongue 241, which gradually extends inward from the top of the mounting slot 230 in the insertion direction of the thermistor 300, and is outwardly expanded during the insertion of the thermistor 300, and uses its own elastic force to tightly press the thermistor 300 against the compressor top cover 100 to prevent contact breakage, and effectively prevent the thermistor 300 from falling off, further improving the detection accuracy.

[0044] In an alternative embodiment, the terminal cover 200 includes a cover body 210 and a mounting portion 220 extending outward from one side of the cover body 210, and the mounting slot 230 is recessed upward from the bottom of the mounting portion 220.

[0045] It can be understood that the terminal cover 200 includes two main parts, namely the cover body 210 and the mounting portion 220. The cover body 210 is the original basic structure of the terminal cover 200, and the mounting portion 220 is a specific area additionally extended from the cover body 210, which is carefully designed in shape and size to accommodate the thermistor 300.

[0046] When the terminal cover 200 is buckled on the compressor top cover 100 as a whole, since the mounting slot 230 is recessed upward from the bottom of the mounting portion 220, a part of the compressor top cover 100 can be exposed from the bottom of the mounting slot 230 as a detection object of the thermistor 300. After the thermistor 300 is inserted into the mounting slot 230, the bottom of the thermistor 300 can directly contact the compressor top cover 100, so that the temperature of the compressor can be timely and effectively detected, so that protective measures can be taken in time when the temperature of the compressor is high.

[0047] In an alternative embodiment, one end of the mounting slot 230 is opened as a mounting opening 231, and the other end of the mounting slot 230 is provided with a baffle 232 for stopping the thermistor 300.

[0048] In the actual installation process, first, the terminal post cover 200 is buckled on the compressor top cover 100 as a whole, and the stable connection between the two is ensured. Then, through the installation port 231, the thermistor 300 is slowly pushed into the installation slot 230. In the process of pushing, the thermistor 300 will contact the elastic tongue 241 and press the elastic tongue 241 upwards, prompting the elastic tongue 241 to gradually bend and accumulate elastic force. When the pushing end of the thermistor 300 abuts against the baffle 232, it is proved that the thermistor 300 has been installed in place. At this time, the elastic tongue 241 uses the accumulated elastic force to tightly press the thermistor 300 on the compressor top cover 100. This elastic fixing method not only simplifies the installation process, makes the installation of the thermistor 300 quick and easy, but also enhances the stability of the installation. Even in the working environment of long-term vibration of the compressor, it can effectively prevent the thermistor 300 from loosening or displacement, and ensure that the accuracy and reliability of temperature detection are maintained.

[0049] In one example, the mounting portion 220 is located on the right side of the cover body 210 and extends along the front-rear direction on the right side of the cover body 210. The extension direction of the installation slot 230 is the same as that of the mounting portion 220, the installation port 231 is located at one end of the installation slot 230 away from the cover body 210, and the baffle 232 is located at one end of the installation slot 230 adjacent to the cover body 210.

[0050] In another example, the mounting portion 220 is also located on the right side of the cover body 210, but extends along the left-right direction on the right side of the cover body 210. The extension direction of the installation slot 230 is the same as that of the mounting portion 220, the installation port 231 is located at one end of the installation slot 230, and the baffle 232 is located at the other end of the installation slot 230.

[0051] Of course, the above setting position and extension direction of the mounting portion 220 are only illustrative. Based on the understanding of the above embodiments, the layout position and extension direction of the mounting portion 220 can be easily changed by those skilled in the art according to different compressor working environments or installation requirements, for example, the mounting portion 220 extends along the front-rear / left-right direction on the front side / rear side of the cover body 210, and these changes should fall within the protection scope of the present application.

[0052] In this embodiment, the cover body 210 and the mounting portion 220 of the terminal post cover 200 are both made of high-temperature-resistant plastic material, so as to ensure that they can still maintain the stability and durability of the structure in a high-temperature environment. The elastic tongue 241 is made of elastic metal material, such as stainless steel, so as to ensure that the elastic tongue 241 has sufficient elasticity to tightly press the thermistor 300 on the compressor top cover 100.

[0053] In an optional embodiment, the top of the mounting groove 230 can be fixed with a pressing plate 240, and the upper end of the elastic tongue 241 can be fixed to the pressing plate 240. The presence of the pressing plate 240 increases the structural strength of the top of the mounting groove 230, making the entire mounting structure more robust and durable.

[0054] Specifically, when the thermistor 300 is pushed into the mounting groove 230 and contacts the elastic tongue 241, the tongue will bend due to the force and exhibit good resilience. Since the upper end of the elastic tongue 241 is firmly fixed on the pressing plate 240, it ensures that the elastic tongue 241 remains stable during bending and rebounding, thereby more effectively fixing the thermistor 300 on the compressor top cover 100 and preventing it from loosening due to vibration or temperature changes.

[0055] It is worth mentioning that the elastic tongue 241 in this embodiment is integrally formed with the pressing plate 240. Compared to the method of separately fixing the elastic tongue 241 made of metal on the mounting portion 220 made of plastic, the integrated design not only simplifies the installation process and reduces manufacturing costs, but more importantly, it significantly enhances the strength and reliability of the connection, avoiding the problem of breaking or cracking due to material differences or improper installation.

[0056] In an optional embodiment, the pressing plate 240 is completely covered in the mounting portion 220 at the top of the mounting groove 230.

[0057] This design achieves the full embedding of the pressing plate 240, making it integrated with the mounting portion 220 as a unified whole. This seamless combination not only enhances the stability and reliability of the mounting structure, but also prevents external factors (such as vibration, temperature changes, etc.) from affecting the connection between the pressing plate 240 and the mounting portion 220, thereby prolonging the service life of the mounting structure.

[0058] At the same time, this design also helps to improve the overall aesthetics of the mounting structure. Since the pressing plate 240 is completely hidden inside the mounting portion 220, the presence of the pressing plate 240 cannot be seen from the outside, making the entire mounting structure look cleaner and more beautiful.

[0059] In addition, completely covering the pressing plate 240 inside the mounting portion 220 can also simplify the installation process. During installation, only the mounting portion 220 needs to be fixed on the compressor top cover 100, and the pressing plate 240 will be firmly fixed in place without the need for additional fixing operations. This not only saves installation time, but also reduces installation difficulty.

[0060] In another optional embodiment, the pressing plate 240 is completely covered in the mounting portion 220 at the top of the mounting groove 230.

[0061] In this design, the pressure plate 240 is not completely enclosed within the mounting portion 220; rather, its peripheral portion is embedded within the mounting portion 220. In this case, the lower surface of the pressure plate 240 acts as the top wall of the mounting groove 230, helping to maintain the integrity and stability of the mounting groove 230. The peripheral portion of the pressure plate 240 embedded within the mounting portion 220 also allows for a tight fit. Since the pressure plate 240 does not need to be completely covered, the mounting portion 220 can be designed to be thinner and lighter, thereby reducing the overall height of the mounting portion 220. This not only helps save materials but also makes the mounting structure more compact.

[0062] In the embodiment shown in the accompanying drawings of this utility model, the mounting groove 230 is an elongated groove extending front to back, the upper surface of the compressor top cover 100 is a plane, and the thermistor 300 is a horizontally placed columnar component. When the thermistor 300 is correctly installed in the mounting groove 230, it forms a linear contact surface with the compressor top cover 100. The width of the pressure plate 240 is greater than the width of the mounting groove 230, and its left and right sides are pressed firmly into the mounting portion 220 at the top of the mounting groove 230 by heat fusion, ensuring that the position of the pressure plate 240 is firm and reliable, and will not loosen or shift.

[0063] In an alternative embodiment, the top of the mounting portion 220 is cut downward to form a central groove 221, the cutting depth of which is configured to expose the pressure plate 240 at the bottom of the groove.

[0064] like Figure 2 As shown, the mounting part 220 is a cuboid extending from front to back, with the central groove 221 cut out in the middle area. The pressure plate 240 can be directly observed from above through the central groove 221.

[0065] In other words, in order to ensure the structural strength of the mounting part 220, the original thickness of its front and rear ends is deliberately retained in this embodiment. This not only maintains the load-bearing capacity of the mounting part 220 in critical stress areas, but also ensures the stability of the entire structure.

[0066] At the same time, by cleverly cutting a groove in the central area, the use of materials can be optimized while ensuring structural strength, making the mounting part 220 look lighter and significantly reducing the amount of material used, thereby achieving the goal of saving costs.

[0067] Furthermore, the pressure plate 240 has a vertically penetrating window 242 corresponding to the elastic pressure tongue 241, through which the real-time shape of the elastic pressure tongue 241 can be directly observed.

[0068] Specifically, when the thermistor 300 is installed to the designated position, the deformation condition of the elastic tongue 241 or whether it has been correctly crimped to the thermistor 300 can be clearly seen through this window 242. This not only improves the accuracy and reliability of installation, but also greatly simplifies the inspection step in the installation process, making the installation process more efficient and intuitive. The design of the window 242 can also play a role in subsequent maintenance or troubleshooting, allowing for quick and easy positioning and inspection of the state of the elastic tongue 241, thereby effectively reducing maintenance costs and difficulty.

[0069] In addition, the introduction of the window 242 enhances the heat dissipation effect of the thermistor 300 to some extent. Because the window 242 provides an additional air flow path, the heat generated by the thermistor 300 during operation can be more effectively dissipated, thereby reducing its operating temperature, prolonging its service life, and improving the accuracy of temperature detection.

[0070] It is worth mentioning that the size of the baffle 232 can also be smaller than the longitudinal cross-sectional size of the mounting groove 230, leaving a certain gap between its periphery and the mounting groove 230. These gaps do not completely close the mounting groove 230, allowing air to flow freely in these small spaces between the baffle 232 and the mounting groove 230, thereby effectively facilitating heat dissipation. In short, this design of incomplete closure not only ensures the flexibility of the structure, but also ingeniously integrates the heat dissipation function, providing additional protection for the safe and stable operation of the thermistor 300.

[0071] In an optional embodiment, the number of elastic tongues 241 is multiple, such as two, three, etc. Multiple elastic tongues 241 can be arranged at intervals along the insertion direction of the thermistor 300.

[0072] Such a layout design ensures that when the thermistor 300 is inserted, it can be subjected to a common and uniform pressing action from multiple elastic tongues 241. Each elastic tongue 241 has a certain elasticity and restoring force, and when the thermistor 300 gradually advances to the predetermined position, these elastic tongues 241 will be in contact with the thermistor 300 in turn and generate an appropriate amount of pressure, thereby ensuring that the thermistor 300 is firmly clamped in the installation position. This multi-point pressing method not only improves the stability of the installation, but also helps to maintain good contact between the thermistor 300 and the compressor top cover 100, thereby optimizing its performance. In addition, since the elastic tongues 241 are arranged at intervals, a certain space is formed between them, which helps to reduce the local stress concentration phenomenon caused by pressing, prolonging the service life of the thermistor 300 and its surrounding components.

[0073] In the free state, the angle between the extension direction of the elastic tongue 241 and the horizontal direction can be less than or equal to 60°. Specific angles such as 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. can meet the requirements. The core purpose of this design is to reduce the resistance of the thermistor 300 in the installation groove 230, and to ensure the smoothness of the insertion of the thermistor 300. At the same time, it can also ensure that the elastic tongue 241 can uniformly and efficiently exert its function when subjected to external force, not only stably maintaining the connection state, but also skillfully avoiding the stress concentration problem caused by too large angle, thereby prolonging the service life of the overall structure.

[0074] In the free state, the height of the elastic tongue 241 in the vertical direction can be greater than or equal to 1mm. Specific such as 1mm, 2mm, 3mm, 4mm, 5mm, etc. can meet the requirements. This design not only provides sufficient deformation space for the elastic tongue 241, so that it can respond flexibly under stress, but also ensures stability and durability in actual work process. Such design not only meets the demand of elastic deformation, but also guarantees the rigidity and durability of the structure, which is an important embodiment of performance and reliability.

[0075] In the free state, the width of the elastic tongue 241 is greater than or equal to 1 / 2 of the width of the installation groove 230. This design aims to achieve more efficient and stable pressure effect. When the elastic tongue 241 is subjected to downward pressure, it will deform moderately, and its shape can closely fit the outer contour of the thermistor 300, so as to achieve more closely pressure holding. This profiling design not only enhances the contact area between the tongue and the thermistor 300, but also significantly increases the friction between them, effectively preventing the thermistor 300 from loosening or falling out under vibration or external force.

[0076] The thickness of the elastic tongue 241 can be 0.2mm-1.0mm. Specific such as 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, etc. Preferably, the thickness of the elastic tongue 241 is 0.5mm. The thickness of the pressure plate 240 is the same as that of the elastic tongue 241. In this way, the bending and rebound performance can be guaranteed, and the appropriate pressure can be applied.

[0077] The above "free state" refers specifically to the state in which the thermistor 300 has not been inserted into the installation groove 230, that is, the elastic tongue 241 has not been subjected to external force and remains in its original shape.

[0078] The elastic tongue 241 is designed in width, height, thickness, etc., so that the elastic tongue 241 has a rising height greater than or equal to 0.5 mm after the thermistor 300 is installed in place. The rising height refers to the rising height of the end of the elastic tongue 241 in contact with the thermistor 300. By limiting the rising height to be greater than or equal to 0.5 mm, the elastic tongue 241 can not only effectively hold the thermistor 300, but also effectively limit the movement of the thermistor 300 along its length direction, so as to prevent the thermistor 300 from being accidentally pulled out.

[0079] In the embodiment, in order to ensure the stability of the thermistor 300 in the installation groove 230, the diameter of the installation groove 230 is designed to be equal to or slightly larger than the diameter of the thermistor 300, so as to prevent the thermistor 300 from shaking left and right in the installation groove 230.

[0080] In some alternative embodiments, elastic tongues 241 can be additionally arranged on both sides of the installation groove 230. Specifically, one or more elastic tongues 241 can be arranged on each side, which gradually extend inward from the side wall of the installation groove 230 along the direction of insertion of the thermistor 300. When the thermistor 300 is pushed into the installation groove 230, it will simultaneously press the elastic tongues 241 on both sides. The pressed elastic tongues 241 will tightly adhere to the side surface of the thermistor 300, thereby effectively limiting the left and right shaking of the thermistor 300 in the installation groove 230, and further improving the stability thereof.

[0081] The thermistor mounting structure of the embodiment has a stable and reliable fixing mechanism, excellent vibration adaptability, simple installation and maintenance process, and excellent cost-effectiveness, which significantly improves the technical performance and brings a more ideal technical solution to the compressor temperature monitoring field. The stable fixing mode ensures the stable operation of the thermistor 300 under complex working conditions, effectively resisting the potential impact of vibration, and the ease of design makes installation and maintenance easy and fast, greatly saving time and labor cost. In addition, by optimizing the cost structure, the utility model not only ensures high performance, but also maximizes economic benefits.
