Description
Technical Field
[0001] This utility model relates to the field of semiconductor manufacturing technology, and in particular to a pipe connector. Background Technology
[0002] In semiconductor manufacturing, wafers undergo CMP (Chemical Mechanical Polishing) treatment. When polishing wafers using a polishing machine, a peristaltic pump and tubing are used to deliver slurry or chemical cleaning agent to the wafer surface. The tubing connected to the peristaltic pump includes flexible hoses and rigid tubing; the flexible hoses are typically rubber tubing, and the rigid tubing is typically PFA (Polyfluoroalkoxy) tubing. One end of the flexible hose connects to the peristaltic pump, and the other end connects to one end of the rigid tubing; the other end of the rigid tubing extends above the polishing disc inside the polishing machine.
[0003] Currently, when connecting flexible and rigid tubing, the rigid tubing is typically inserted directly into the flexible tubing, and then the connection is secured with cable ties. However, when the pressure inside the pipeline is high, the connection between the flexible and rigid tubing can easily detach, leading to leakage of the delivered solution. Utility Model Content

[0026] like Figure 1 As shown, this embodiment provides a pipe connector, including a connecting part 1 and a fixing part 2. The connecting part 1 includes a protruding section 11, a transition section 12, a fastening section 13, and a cylindrical section 14 connected in sequence. The protruding section 11, the transition section 12, the fastening section 13, and the cylindrical section 14 are respectively provided with sequentially connected through holes along an axial direction parallel to the protruding section 11. The outer surface of the protruding section 11 is provided with a protruding structure 111. The outer surface of the fastening section 13 is provided with a first fixing structure 131. The cylindrical section 14 is hollow in shape. The fixing part 2 is hollow in shape, and the inner wall of the fixing part 2 is provided with a second fixing structure that cooperates with the first fixing structure 131.
[0027] This embodiment provides a pipe connector, including a connecting part 1 and a fixing part 2. The connecting part 1 includes a raised section 11, a transition section 12, a fastening section 13, and a cylindrical section 14 connected in sequence. When using this pipe connector to connect a flexible hose and a rigid pipe, the flexible hose is fitted onto the raised section 11, where the raised structure 111 can be used to fix the flexible hose. To increase the fixing effect, a cable tie can be added to the flexible hose. The fixing part 2 is fitted onto the rigid pipe, and then the rigid pipe is fitted onto the cylindrical section 14. Finally, the fixing part 2 is fixed to the first fixing structure 131 on the fastening section 13, so that the rigid pipe is fixed between the fixing part 2 and the cylindrical section 14. The unexpected effect of this pipe connector is that it can firmly connect flexible hoses and rigid pipes, effectively preventing the flexible hoses and rigid pipes from detaching, and making it convenient and quick to connect and disconnect pipes.
[0028] Preferred, such as Figure 1 As shown, the axes of the protruding section 11, the transition section 12, the fastening section 13, and the cylindrical section 14 are on the same straight line, which allows the liquid to flow smoothly within the pipe joint. In other embodiments, the pipe joint can be made into a right angle or other shapes.
[0029] Preferred, such as Figure 1 As shown, the protrusion structure 111 is serrated, which improves its ability to secure the hose. In other embodiments, the protrusion structure 111 may be dotted or have other shapes.
[0030] Preferred, Reference Figure 1As shown, the protruding structure 111 is arranged circumferentially around the outer surface of the protruding segment 11, which improves the fixing effect of the protruding structure 111 on the hose. In other embodiments, the protruding structure 111 may be in the shape of a semi-circular ring or a spiral.
[0031] Preferred, such as Figure 1 As shown, there are multiple protrusions 111, which can improve the fixing effect of the protrusions 111 on the hose. In other embodiments, the protrusion 111 can be a continuous spiral protrusion.
[0032] Preferred, such as Figure 1 As shown, multiple protrusions 111 are evenly distributed on the outer surface of the protrusion section 11, which can improve the fixing effect of the protrusions 111 on the hose.
[0033] Preferred, such as Figure 1 As shown, the first fixing structure 131 has an external thread, and the second fixing structure has an internal thread, which facilitates the connection and disassembly of the fixing part 2. In other embodiments, the first fixing structure 131 may be an annular protrusion or other structure, and the second fixing structure may be an annular groove or other structure.
[0034] Preferred, such as Figure 1 As shown, the transition section 12 is a hollow prism. The prism shape of the transition section 12 allows operators to easily hold it by hand and insert the flexible hose and rigid hose into the two ends of the pipe connector, respectively. In other embodiments, the transition section 12 can be a hollow cylinder or other shapes.
[0035] Preferred, such as Figure 1 As shown, the fixing part 2 is a hollow cylinder, which facilitates its manufacture. The fixing part 2 can be a nut. In other embodiments, the fixing part 2 can be a hollow prism.
[0036] Preferred, such as Figure 1 As shown, the end of the cylindrical segment 14 away from the fastening segment 13 has a rounded chamfer, which facilitates the insertion of the rigid tube into the cylindrical segment 14. If the rigid tube is difficult to insert into the cylindrical segment 14, it can be cold-expanded before being inserted into the cylindrical segment 14. In other embodiments, the end of the cylindrical segment 14 away from the fastening segment 13 may not have a chamfer.
[0037] Preferred, such as Figure 1As shown, the maximum outer diameter of the protruding structure 111 is equal to or slightly larger than the inner diameter of the hose, the outer diameter of the cylindrical section 14 is equal to or slightly larger than the outer diameter of the rigid pipe, and the inner diameter of the fixing part 2 is equal to the outer diameter of the rigid pipe. This can further improve the fixing effect. If the inner diameters of the hose and the rigid pipe are large, sealing rings or Teflon tape can be added between the protruding section 11 and the hose, and between the cylindrical section 14 and the rigid pipe to improve the fixing and sealing effects.
[0038] In summary, the present invention provides a pipe connector comprising a connecting part 1 and a fixing part 2. The connecting part 1 includes a raised section 11, a transition section 12, a fastening section 13, and a cylindrical section 14 connected sequentially. When using this pipe connector to connect a flexible hose and a rigid pipe, the flexible hose is fitted onto the raised section 11, where the raised structure 111 can be used to fix the flexible hose. To enhance the fixing effect, a cable tie can be added to the flexible hose. The fixing part 2 is then fitted onto the rigid pipe, and the rigid pipe is fitted onto the cylindrical section 14. Finally, the fixing part 2 is fixed to the first fixing structure 131 on the fastening section 13, thereby fixing the rigid pipe between the fixing part 2 and the cylindrical section 14. This pipe connector has the unexpected effect of firmly connecting flexible hoses and rigid pipes, effectively preventing the flexible hoses and rigid pipes from detaching, and providing convenience and speed in connecting and disconnecting pipes.
