Abstract
Abstract A water-proof connector having a sealing ring (30) in the connection between a male connector housing (20,20a,20b) having a male connector (21) and a female connector housing (10) having a female connector (11) is disclosed. An engaging mechanism (26A,26B,50A,50B,60A,60B) holds the sealing ring (30) on the male connector housing. The insertion or separation of the male connector housing (20,20a,20b) and the female connector housing (10) is facilitated and the water-proof effect is improved.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
1 A water-proof connector comprising a sealing ring (30) in the coupling between a female connector housing (10,10a,10b) having a female connector (11) and a male connector housing (20,20a,20b) having a male connector (21), wherein said sealing ring (30) includes a cylindrical portion (31) and an engaging portion (32), said cylindrical portion (31) including annular protrusions (35A,35B; 36A,36B), said engaging portion (32) including at least two engaging protrusions (37A,37B; 37A',37B'), sealing ring stopper slots (26A,26B; 50A,50B; 60A,608) being formed in a peripheral wall (25) of said male connector housing for receiving the engaging protrusions of said sealing ring, said engaging protrusions of said sealing ring being engaged with said sealing ring stopper slots of said female connector housing while said female connector housing is inserted into said male connector housing, thereby pressing said annular protrusions of said sealing ring for waterproofing purposes.
Claim 2
Dependent Claim
142 words
1 A water-proof connector comprising a sealing ring (30) in the coupling between a female connector housing (10,10a,10b) having a female connector (11) and a male connector housing (20,20a,20b) having a male connector (21), wherein said sealing ring (30) includes a cylindrical portion (31) and an engaging portion (32), said cylindrical portion (31) including annular protrusions (35A,35B; 36A,36B), said engaging portion (32) including at least two engaging protrusions (37A,37B; 37A',37B'), sealing ring stopper slots (26A,26B; 50A,50B; 60A,608) being formed in a peripheral wall (25) of said male connector housing for receiving the engaging protrusions of said sealing ring, said engaging protrusions of said sealing ring being engaged with said sealing ring stopper slots of said female connector housing while said female connector housing is inserted into said male connector housing, thereby pressing said annular protrusions of said sealing ring for waterproofing purposes.
