Abstract
A joint structure for a refrigerant discharge tube of a hermetic reciprocal compressor having a connecting member fit around the refrigerant discharge tube, the connecting member having a shape corresponding to a connecting hole in a cylinder block, thereby allowing the connecting member to be press-caulked. The refrigerant discharge tube is directly connected to the cylinder block. The connecting hole is multi-layered and may be formed into at least two steps. The connecting member is pre-assembled in the connecting hole by transition-fitting. Accordingly, as the connecting member is press-fit in the connecting hole by a caulking-jig, the connecting member is expanded, and the connecting member is more securely fit in the connecting hole. Further, a thread portion having a pitch in a range of 2 to 5 threads is formed on an inner circumference of the connecting hole. Accordingly, the expanded connecting member penetrates into the thread portion, strengthening the connection between the connecting member and the connecting hole. Since the refrigerant discharge tube is directly connected to the cylinder block, structure is simplified, while the number of assembling steps is reduced. As a result, productivity increases and the manufacturing costs decrease. Further, since the connecting member is fit in the connecting hole by the press-caulking instead of the brazing, higher durability is guaranteed and thus, the breakage of the refrigerant discharge tube is prevented.

For assembly, the connecting member is pre-assembled in the connecting hole by transition-fitting, and then is securely press-fit in the connecting hole by being expanded therein under the pressure of a caulking jig.
- According to the preferred embodiment of the present invention, the connecting hole has a thread portion having a pitch in the range of 2 to 5 threads, and thus, the connecting member is more securely fit in the connecting hole because the connecting member is expanded by the pressure provided by the caulking jig.
- The connecting member can be formed of a soft iron metal or a soft non-iron metal.

member 120 is pressed from the rear side by thecaulking jig 130, press-fitting the connectingmember 120 into the connectinghole 101. At this time, the connectingmember 120 expands inwardly and outwardly, coming into close contact with therefrigerant discharge tube 110 relative to therefrigerant discharge tube 110 inserted in theinsertion hole 120 a of the connectingmember 120, with the connectinghole 101 and the connectingmember 120 contacting each other very tightly. Due to the presence of thethread portion 101 a on the inner circumference of the connectinghole 101, the connectingmember 120 penetrates into the threadedportion 101 a during expansion, thereby being press-fit in the connectinghole 101 tightly. - FIG. 4 is a view showing the connecting
member 120 being press-caulked in the connectinghole 101. As shown in FIG. 4, therefrigerant discharge tube 110 is secured in thecylinder block 100 due to the expansion of connectingmember 120 into the connectinghole 101. As described above, the connectingmember 120 is secured in the connectinghole 101 by being expanded under the external pressure of the caulking jig 130 (FIG. 3), and is further tightly secured due to the connectingmember 120 being partially and fixedly penetrated into thethread portion 101 a formed on the inner circumference of the connectinghole 101. As a result, a strong binding force is acquired, and the connectingmember 120 is not separated from the connectinghole 101. - FIG. 5 shows the hermetic reciprocal compressor having the joint structure for a refrigerant discharge tube as described above. As shown in FIG. 5, the
refrigerant discharge tube 110 is directly secured to thecylinder block 100 by the connectingmember 120. - As described above, according to the present invention, since the
refrigerant discharge tube 110 is directly connected to thecylinder block 100, the structure becomes simplified, while the number of assembly steps required for assembling the compressor is reduced. As a result, manufacturing efficiency improves and manufacturing costs are reduced. - Further, since the connecting member is secured by press-caulking, instead of brazing, durability is increased, and thus, breakage of the
refrigerant discharge tube 110 can be prevented. - Although a preferred embodiment of the present invention has been described, it will be understood by those skilled in the art that the present invention should not be limited to the described preferred embodiment, but various changes and modifications can be made to remain within the spirit and scope of the present invention as defined by the appended claims and their equivalents.
