Abstract
A waterproof plug (30) fitted to an outer circumference of a wire (9) and inserted into a terminal insertion cavity (10a) of a connector housing (10) for sealing a space between the wire and the connector housing comprises an elastic cylindrical body (2) formed with: an inner corrugated sealing portion (3) for sealing the outer circumference of the wire; an outer corrugated sealing portion (4) for sealing the inner circumference of the terminal insertion cavity (10a) of the connector housing (10); and, in particular, a press portion (31) expanding radially outward at a free end of the elastic cylindrical body, the press portion being sufficiently deformable radially inward gradually against the wire, when the elastic cylindrical body (2) is being inserted into the terminal insertion cavity of the connector housing. The press portion (31) is preferably divided into a plurality of separated press portions (31d) with a space interposed between the two adjacent separated press portions (31d) for providing an easy deformation of the separated press portions into the spaces, respectively. The waterproof plug thus constructed is excellent in both the wire insertion and sealing characteris…
