Description

Technical Field

[0001] This utility model belongs to the field of compressor technology, specifically relating to a top cover structure and a compressor. Background Technology

[0002] When a compressor is installed in an air conditioning system and put into operation, it will continuously generate regular vibrations during operation, and at the same time, it will release a large amount of heat, causing the compressor top cover area to be in a high-temperature environment for a long time.

[0003] The connected power and system wiring harnesses will continuously experience slight displacement and swaying under the constant vibration. Coupled with the continuous baking of high temperatures, the insulation of the power and system wiring harnesses will gradually lose its toughness and show signs of aging and cracking. The internal wires will also experience accelerated wear and tear due to repeated micro-friction.

[0004] Over time, the originally neatly arranged power and system wiring harnesses will gradually become unrestrained, resulting in tangling and compression. This tangling not only accelerates insulation damage due to uneven stress, but can also lead to loose terminals and poor contact. Once the insulation is completely damaged, the exposed wires will short-circuit, posing a risk of electric shock. Furthermore, the arcing caused by poor contact, or the high temperature during a short circuit, can easily ignite surrounding flammable materials such as plastic components and insulation, ultimately causing fires and other serious safety accidents, posing a significant threat to personal and property safety. Summary of the Invention

[0005] To address the shortcomings of the prior art, this utility model provides a top cover structure and compressor that can protect the terminal components, fix the wiring harness, and improve product safety.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a top cover structure, including: A top cover body, wherein a first mounting through hole is formed on the top cover body; A terminal assembly, wherein the terminal assembly is mounted on the first mounting through hole; A first stop, disposed on the top cover body, surrounds the outer side of the terminal assembly and forms a first notch for avoiding wiring of the terminal assembly; and A fixing base is disposed on the top cover body and adjacent to the terminal assembly. The fixing base is used to fix the wire harness connected to the terminal assembly.

[0007] In some implementations, the first barrier includes a fixed plate and a barrier upright plate connected together; The fixing plate is connected to the upper end face of the top cover body, and the enclosure plate surrounds the outside of the terminal assembly. This structural design can realize the connection relationship between the first barrier and the top cover body and the enclosure and protection function of the terminal assembly.

[0008] In some implementations, the enclosure panel has multiple second mounting through holes for sensor installation. The presence of multiple second mounting through holes on the enclosure panel facilitates the installation of multiple sensors, thereby further improving the monitoring of compressor performance.

[0009] In some implementations, the fixing plate is connected to the upper end face of the top cover body by welding or fasteners to ensure the connection stability between the fixing plate and the top cover body.

[0010] In some implementations, the fixing base includes a base plate and a first clamping plate and a second clamping plate connected to the base plate, wherein the first clamping plate and the second clamping plate are disposed opposite to each other; The base plate is connected to the upper end face of the top cover body. The first clamp and the second clamp are used to fix the wire harness connected to the terminal assembly. This structural design enables the fixing seat to fix the wire harness.

[0011] In some implementations, the upper end of the first clamping plate has a first convex bulge in the direction facing the second clamping plate; The upper end of the second clamping plate has a second protrusion facing the first clamping plate. The gap between the upper ends of the first clamping plate and the second clamping plate is reduced by the first protrusion and the second protrusion. This ensures that the wire harness is fixed between the first clamping plate and the second clamping plate, while also preventing the wire harness from coming off the fixing seat.

[0012] In some implementations, the fixing base is made of plastic, giving it a certain degree of elasticity and facilitating the fixing of the wire harness.

[0013] In some implementations, the upper end of the first or second clamping plate extends outward to form a grounding mounting plate, thereby connecting the grounding wire.

[0014] In some implementations, the grounding mounting plate has a third mounting through hole for grounding, which facilitates the connection of the grounding wire.

[0015] On the other hand, this application also provides a compressor, including a housing, a pump body structure, a motor structure, and a top cover structure as described in any one of the above. The pump body structure and the motor structure are installed inside the housing, and the top cover structure is connected to the upper end of the housing.

[0016] In summary, this utility model has at least the following advantages: 1. The top cover structure provided by this utility model provides a first stop on the outside of the terminal assembly, which encloses the terminal assembly and separates it from the compressor system wiring harness. This prevents the wiring harness from contacting the terminal assembly after aging and causing safety hazards, thus protecting the terminal assembly. A fixing seat is provided to fix the wiring harness connected to the terminal assembly, preventing the wiring harness from shifting due to vibration during long-term use of the compressor and causing it to become entangled or squeezed with the terminal assembly, thereby improving the safety of the compressor.

[0017] 2. The compressor provided by this utility model, after applying the above-mentioned top cover structure with a first stop and a fixed seat, can improve the safety of compressor use. Attached Figure Description

Detailed Implementation

[0019] To facilitate understanding of the present invention, a more comprehensive description will be given below in conjunction with the accompanying drawings and specific embodiments. The drawings illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0021] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Example 1: Please see Figure 1 and Figure 2 A top cover structure is used for the sealing protection of the top of the compressor, which isolates the core components inside the compressor from the external environment, so as to prevent impurities such as dust, water vapor and oil from entering the compressor, avoiding corrosion, wear or short circuit of components, and also preventing the leakage of refrigerant oil inside the compressor, ensuring the lubrication and stable refrigeration cycle of the system.

[0024] The top cover structure includes a top cover body 100, on which a first mounting through hole 110 is formed. A terminal assembly 200 is mounted on the first mounting through hole 110. The terminal assembly 200 serves to connect the internal and external components of the compressor. Specifically, the external power supply harness transmits electrical energy to the motor windings inside the compressor through the terminal assembly 200, providing power for the compressor's operation. In practical applications, depending on the type of compressor, such as a single-phase or three-phase compressor, the corresponding terminal assembly 200 and wiring method are matched to ensure that the motor stator and rotor can operate stably according to the set phase sequence and voltage.

[0025] In one example, the terminal assembly 200 includes three connection terminals. These terminals securely fasten the external power harness using screws, clips, and other mechanisms, preventing loosening or detachment of the wiring due to compressor vibration, thus avoiding faults such as poor contact or open circuits. Simultaneously, the housings of the connection terminals are mostly made of high-temperature resistant, highly insulating, and flame-retardant materials, effectively isolating the top cover body 100 from high temperatures, protecting the wiring components, and reducing the risk of short circuits and leakage. Furthermore, the interface specifications of the connection terminals conform to industry-standard specifications, facilitating rapid wiring and assembly during production and simplifying wiring disassembly and replacement during later maintenance, thereby improving production and maintenance efficiency.

[0026] A first stop 300 is provided on the top cover body 100. The first stop 300 surrounds the outside of the terminal assembly 200 and forms a first notch for avoiding wiring of the terminal assembly 200.

[0027] As is known, the terminal assembly 200 is used to connect to an external power supply harness to deliver electrical energy to the motor windings inside the compressor. Therefore, in order to avoid interfering with the wiring operation of the terminal assembly 200, a first notch is formed on the first stop 300 relative to the wiring direction of the terminal assembly 200.

[0028] As is known from the background technology, during the operation of a compressor, a certain amount of vibration and continuous high temperature baking will occur. The vibration will cause the power harness and system harness to shift in position, resulting in entanglement or compression. The high temperature will cause the insulation of the harness to age and crack. Under the influence of vibration and high temperature, the exposed wire cores are prone to contact with the terminal assembly 200, which may lead to short circuit, electric shock and fire risks. Therefore, in order to improve safety, a first baffle 300 is set to surround the outside of the terminal assembly 200. The first baffle 300 plays a role in enclosing the terminal assembly 200 and separating it from the compressor system harness, so as to avoid the safety hazards caused by the aging of the harness contacting the terminal assembly 200, and thus protect the terminal assembly 200.

[0029] A fixing seat 400 is provided on the top cover body 100. The fixing seat 400 is disposed adjacent to the terminal assembly 200 and is used to fix the wire harness connected to the terminal assembly 200.

[0030] To prevent the power harness from becoming loose or making poor contact with the terminal assembly 200 due to compressor vibration, the power harness is fixed to the mounting base 400, and the end of the power harness is connected to the terminal assembly 200 to improve the positional stability of the power harness.

[0031] The top cover structure provided in this embodiment provides a first baffle 300 on the outside of the terminal assembly 200. The first baffle 300 encloses the terminal assembly 200 and separates it from the compressor system wiring harness. This prevents the wiring harness from coming into contact with the terminal assembly 200 after aging and thus avoids potential safety hazards. It also protects the terminal assembly 200. A fixing seat 400 is provided to fix the wiring harness connected to the terminal assembly 200. This prevents the wiring harness from shifting due to vibration during long-term use of the compressor and causing it to become entangled or squeezed with the terminal assembly 200, thereby improving the safety of the compressor.

[0032] Example 2: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figure 1 and Figure 2 Based on the above, refer to Figure 3 and Figure 4 .

[0033] In this embodiment, the first barrier 300 includes a fixed plate 310 and a barrier plate 320 connected to each other; the fixed plate 310 is connected to the upper end face of the top cover body 100, and the barrier plate 320 surrounds the outside of the terminal assembly 200. This structural design can realize the connection relationship between the first barrier 300 and the top cover body 100 and the enclosure and protection function of the terminal assembly 200.

[0034] Specifically, the hoarding upright plate 320 is an arc-shaped upright plate. The arc-shaped upright plate design can avoid the situation where the wire harness skin is easily scratched due to the existence of sharp corners, and it is also easy to process and form. Understandably, the connection between the fixing plate 310 and the hoarding upright plate 320 is adapted to the arc shape of the hoarding upright plate 320.

[0035] Furthermore, the fixing plate 310 is connected to the upper surface of the top cover body 100 by welding or fasteners to ensure the connection stability between the fixing plate 310 and the top cover body 100.

[0036] In some embodiments, the enclosure panel 320 has a plurality of second mounting through holes 321 for sensor mounting. The formation of a plurality of second mounting through holes 321 on the enclosure panel 320 facilitates the mounting of a plurality of sensors to further improve the monitoring of compressor performance.

[0037] For example, two second mounting through holes 321 are formed at intervals on the fence upright plate 320, and a temperature sensor and a pressure sensor are respectively installed at the two second mounting through holes 321.

[0038] The temperature sensor is installed in the second mounting through hole 321 and is close to the top cover body 100. It is used to monitor the temperature of the compressor. When the compressor is overloaded or the refrigerant is insufficient, the exhaust temperature will rise sharply. The temperature sensor will feed back the temperature signal to the main control board, triggering protection mechanisms such as frequency reduction and shutdown to prevent the compressor from burning out due to overheating.

[0039] Pressure sensors are used to monitor the discharge pressure of the refrigeration system and determine whether there are problems such as blockage or excessive refrigerant in the system. If the discharge pressure is too high, the main control board will adjust the operating parameters in time to avoid pipe bursts or compressor damage.

[0040] In some embodiments, the mounting base 400 includes a base plate 410 and a first clamping plate 420 and a second clamping plate 430 connected to the base plate 410, with the first clamping plate 420 and the second clamping plate 430 disposed opposite to each other; the base plate 410 is connected to the upper end face of the top cover body 100, and the first clamping plate 420 and the second clamping plate 430 are used to fix the wire harness connected to the terminal assembly 200. This structural design enables the mounting base 400 to fix the wire harness.

[0041] Furthermore, a first protrusion 421 is formed on the upper end of the first clamping plate 420 facing the second clamping plate 430; a second protrusion 431 is formed on the upper end of the second clamping plate 430 facing the first clamping plate 420. By reducing the gap between the upper ends of the first clamping plate 420 and the second clamping plate 430 through the first protrusion 421 and the second protrusion 431, the wire harness is limited and fixed between the first clamping plate 420 and the second clamping plate 430, while making it difficult for the wire harness to fall off the fixing seat 400.

[0042] Specifically, the first clamping plate 420 and the second clamping plate 430 have a certain length following the extension direction of the wire harness, which can better fix the wire harness. In actual operation, the wire harness is passed through the first protrusion 421 and the second protrusion 431, and is limited and fixed between the lower ends of the first clamping plate 420 and the lower ends of the second clamping plate 430. Understandably, the gap between the lower ends of the first clamping plate 420 and the second clamping plate 430 is larger than the gap between the first protrusion 421 and the second protrusion 431. The purpose of this design is to both limit and fix the wire harness, making it less likely to detach, and to avoid long-term compression of the wire harness, thus ensuring the service life of the wire harness.

[0043] The mounting bracket 400 is made of plastic, which gives it a certain degree of elasticity, making it easy to fix the wire harness.

[0044] In some embodiments, the upper end of the first clamping plate 420 or the second clamping plate 430 extends outward to form a grounding mounting plate 440, which connects to the grounding wire.

[0045] Specifically, a third mounting through hole 441 for grounding is formed on the grounding mounting plate 440 to facilitate the connection of the grounding wire.

[0046] Example 3: This embodiment provides a compressor based on embodiment 1 or 2. Please refer to [link / reference]. Figures 1-4 .

[0047] This embodiment provides a compressor, including a housing, a pump body structure, a motor structure, and a top cover structure as described in Embodiment 1 or Embodiment 2. The pump body structure and the motor structure are installed inside the housing, and the top cover structure is connected to the upper end of the housing.

[0048] The top cover structure includes a top cover body 100, a terminal assembly 200, a first stop 300, and a fixing seat 400. A first mounting through hole 110 is formed on the top cover body 100. The terminal assembly 200 is mounted on the first mounting through hole 110. The first stop 300 and the fixing seat 400 are disposed on the top cover body 100. The first stop 300 surrounds the outside of the terminal assembly 200 and forms a first notch for avoiding wiring of the terminal assembly 200. The fixing seat 400 is disposed on the top cover body 100 and is disposed adjacent to the terminal assembly 200. The fixing seat 400 is used to fix the wire harness connected to the terminal assembly 200.

[0049] The terminal assembly 200 is used to connect the internal and external parts of the compressor. The external power supply harness supplies power to the motor structure through the terminal assembly 200, thereby causing the motor structure and pump body structure to operate and realize the operation of the compressor.

[0050] The compressor provided in this embodiment adopts the top cover structure of Embodiment 1 or Embodiment 2. The top cover has a first baffle 300 on the outside of the terminal assembly 200. The first baffle 300 surrounds the terminal assembly 200 and separates the terminal assembly 200 from the compressor system wiring harness. This prevents the wiring harness from coming into contact with the terminal assembly 200 after aging and causing safety hazards, thus protecting the terminal assembly 200. A fixing seat 400 is provided to fix the wiring harness connected to the terminal assembly 200. This prevents the wiring harness from shifting due to vibration during long-term use of the compressor and causing it to become entangled or squeezed with the terminal assembly 200, thus improving the safety of the compressor.

[0051] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
