The compressor body 10 is provided with a positioning column 11. The terminal assembly 20 has a mounting hole 21. The positioning column 11 is inserted into the mounting hole 21. A sealing structure is provided between the positioning column 11 and the terminal assembly 20. Specifically, the terminal assembly 20 can be installed on the top of the compressor body 10. When the terminal assembly 20 and the compressor body 10 are assembled, the terminal assembly 20 can be positioned on the compressor body 10 by the positioning column 11, thereby improving the assembly efficiency of the compressor 100. By providing a sealing structure between the positioning column 11 and the terminal assembly 20, the gap between the positioning column 11 and the terminal assembly 20 can be sealed, thereby improving the sealing performance of the compressor 100.

[0034] According to the compressor 100 of the embodiment of the utility model, by setting a positioning column 11 on the compressor body 10 and setting a mounting hole 21 on the terminal assembly 20, the assembly efficiency of the compressor 100 can be improved, and a sealing structure is provided between the positioning column 11 and the terminal assembly 20 to prevent water, dust, etc. from entering the interior of the compressor 100, thereby improving the sealing performance of the compressor 100 and further improving the service life of the compressor 100.

[0035] Among them, the positioning column 11 is passed through the mounting hole 21, and a sealing structure is provided between the positioning column 11 and the terminal assembly 20. The sealing structure can be set to different structures. For example, the sealing structure can be a sealing layer arranged between the circumference of the positioning column 11 and the circumference of the mounting hole 21. The sealing layer can seal the gap between the positioning column 11 and the mounting hole 21. The sealing layer can be a sealant, a sealing ring 22, etc.; for another example, the sealing structure can include a sealing ring 22 arranged around the positioning column 11, and the sealing ring 22 is arranged above the mounting hole 21 to seal the gap between the positioning column 11 and the mounting hole 21 of the terminal assembly 20, thereby improving the sealing performance of the compressor 100.

[0036] Combination Figure 1 and Figure 3 The terminal assembly 20 is installed on the compressor body 10. After the positioning column 11 is provided with the mounting hole 21, one end of the positioning column 11 can extend out of the mounting hole 21, and one end of the positioning column 11 can be fixed by the fixing member 30 to lock the terminal assembly 20 and the compressor body 10, thereby improving the installation efficiency of the terminal assembly 20 and the compressor 100 and the structural stability after installation. The fixing member 30 can be a nut, a locking sleeve, etc.

[0037] Combination Figure 2 In some embodiments of the present invention, the sealing structure may include a sealing ring 22, which surrounds the positioning column 11 and contacts and seals with the positioning column 11 and the terminal assembly 20 respectively. Specifically, the sealing ring 22 surrounds the positioning column 11 and contacts and seals with the positioning column 11, and the sealing ring 22 contacts and seals with the terminal assembly 20. The sealing ring 22 may be made of an elastic material, and may form a good sealing effect between the surfaces in contact with the positioning column 11 and the terminal assembly 20. In addition, by providing the sealing ring 22 between the positioning column 11 and the terminal assembly 20, the assembly efficiency can be improved, and later maintenance and component replacement can be facilitated.

[0038] After the terminal assembly 20 is installed on the compressor body 10, the terminal assembly 20 and the compressor body 10 can be locked by the fixing member 30, and after being locked, the fixing member 30 can press the sealing ring 22 between the terminal assembly 20 and the positioning column 11 to improve the sealing effect between the positioning column 11 and the terminal assembly 20.

[0039] Combination Figure 3 and Figure 5 Furthermore, the terminal assembly 20 has a positioning surface 20a away from the compressor body 10, and the inner circumferential surface of the mounting hole 21 is provided with a groove 23, which is open at the positioning surface 20a, and the sealing ring 22 is arranged in the groove 23 to prevent the sealing ring 22 from protruding from the positioning surface 20a. The groove 23 can position the sealing ring 22 and improve the stability of the sealing structure, thereby improving the sealing effect of the compressor 100.

[0040] Among them, the terminal assembly 20 may also have an installation surface 20b opposite to the positioning surface 20a. In other words, the installation surface 20b is in contact with the compressor body 10, wherein the installation hole 21 can pass through the installation surface 20b and the positioning surface 20a, so that after the positioning column 11 of the compressor body 10 passes through the mounting hole 21, it can be locked by the fixing member 30, thereby improving the installation efficiency and structural stability of the compressor 100. After the positioning column 11 passes through the mounting hole 21, the fixing member 30 can be locked to the end of the positioning column 11 extending out of the mounting hole 21, and the sealing ring 22 can be locked between the groove 23 and the fixing member 30, thereby further improving the sealing performance.

[0041] Combination Figures 5 to 7 In some embodiments of the utility model, an annular rib 231 is provided on the inner bottom surface of the groove 23, and the annular rib 231 extends around the mounting hole 21.

After the fixing member 30 locks the compressor body 10 and the terminal assembly 20, the sealing ring 22 can be pressed between the fixing member 30 and the groove 23. The sealing ring 22 is elastically deformed to accommodate the annular rib 231 to form a sealed structure, which can seal the gap between the sealing ring 22 and the groove 23, thereby improving the waterproof performance of the compressor 100.

[0042] Optionally, the sealing ring 22 can form an integral structure with the terminal assembly 20, and the sealing ring 22 can be fixed in the groove 23 of the terminal assembly 20, simplifying the installation steps of the compressor 100 and improving the installation efficiency. The sealing ring 22 and the terminal assembly 20 can be integrally formed or form an assembly.

[0043] Optionally, the sealing ring 22 may form an integral structure with the fixing member 30 , and the sealing ring 22 may be fixed on the fixing member 30 , so as to simplify the installation steps of the compressor 100 and improve the installation efficiency.

[0044] Optionally, combined Figure 3The fixing member 30 may be provided with reinforcing ribs, which may be serrated, and can increase the friction between the fixing member 30 and the sealing ring 22 to prevent the fixing member 30 from loosening due to vibration during long-term use of the compressor 100.

[0045] In some embodiments of the present invention, the inner edge of the sealing ring 22 contacts and seals the outer peripheral surface of the positioning column 11 to seal the gap between the positioning column 11 and the mounting hole 21 to improve the sealing effect. The inner diameter of the sealing ring 22 may not be greater than the outer diameter of the positioning column 11.

[0046] In some embodiments of the present invention, the outer edge of the sealing ring 22 contacts and seals with the inner circumference or bottom surface of the groove 23 to seal the gap between the positioning column 11 and the mounting hole 21 and improve the sealing effect.

[0047] Combination Figure 5 In some embodiments of the present invention, the terminal assembly 20 also has a drain groove 24, which is connected to the groove 23. The drain groove 24 can guide the water flow to prevent water from accumulating in the groove 23, and the drain groove 24 penetrates the side of the terminal assembly 20 along the radial direction of the groove 23. When water flows into the terminal assembly 20, the drain groove 24 can guide the water flow to the outside of the terminal assembly 20 to prevent water from accumulating in the groove 23 for a long time and causing the sealing structure to fail.

[0048] Furthermore, combined with Figures 5 to 7 In the radial outward direction along the groove 23, the bottom surface of the drain groove 24 is inclined toward the compressor body 10, and a guide slope 241 is formed on the bottom surface of the drain groove 24 to guide the water entering the groove 23 to flow to the outside of the terminal assembly 20, thereby improving the drainage efficiency of the water entering the groove 23.

While locking, the sealing ring 22 can be pressed between the fixing member 30 and the terminal assembly 20, thereby improving the sealing effect and improving the efficiency of assembly.

[0051] In some embodiments of the present invention, the sealing structure includes a sealing layer provided between the circumference of the positioning column 11 and the circumference of the mounting hole 21. It can be understood that when the terminal assembly 20 is assembled with the main body of the compressor 100, the positioning column 11 penetrates the mounting hole 21, and there is a gap between the circumference of the positioning column 11 and the circumference of the mounting hole 21 to improve the efficiency of assembly. By providing a sealing layer between the circumference of the positioning column 11 and the circumference of the mounting hole 21, the gap between the positioning column 11 and the mounting hole 21 can be sealed to prevent water, dust, etc. from entering the compressor 100.

Among them, the mounting surface 20b can be in contact with the compressor body 10, and the positioning surface 20a can be away from the compressor body 10. Specifically, the positioning column 11 of the compressor body 10 can pass through the mounting hole 21, and the end of the positioning column 11 can be locked by the fixing member 30. By setting the groove 23 on the inner circumference of the mounting hole 21, the groove 23 is open at the positioning surface 20a to form a countersunk structure, which is convenient for the fixing member 30 to lock the end of the positioning column 11, thereby improving the connection stability between the compressor body 10 and the terminal assembly 20. In addition, a sealing ring 22 may be provided in the groove 23. After the fixing member 30 is locked on the end of the positioning column 11, the sealing ring 22 may be pressed between the fixing member 30 and the groove 23 to seal the gap between the mounting hole 21 and the positioning column 11, thereby improving the sealing performance of the compressor 100.

[0053] Furthermore, the terminal assembly 20 also has a drainage groove 24 , which is connected to the groove 23 and penetrates the side surface of the terminal assembly 20 along the radial direction of the groove 23 .
