WATER SEAL PLUG AND CONNECTOR WITH THE WATER SEAL PLUG

摘要

A connector (10) includes a terminal (5) having an electric connecting portion (52) connected with a mating member (9) at one end of the terminal (5) so as to be placed on the mating member (9) and fastened by a bolt (11) and a nut (12) and a wire connecting portion (55) joined with a terminal end of the electric wire (6) at the other end of the terminal (5), and a connector housing (4) having a terminal receiving section (41), and a water seal plug (1) arranged around the electric wire (6) to seal watertightly the terminal receiving section (41). The water seal plug (1) includes integrally a rubber water seal member (3) and a resin member (2) made of synthetic resin. The water seal member (3) includes a cylindrical main body (30) and an outer lip (31) abutting on an inner surface of the terminal receiving section (41), and a plurality of inner lips (32a, 32b, 32c) abutting on an outer surface of the electric wire (6). A first inner lip (32a) at the nearest position to the terminal (5) is formed to have a lower projecting height then that of the second inner lip (32b) and the third inner lip (32c).
