ABSTRACT:
A waterproof electrical connector. The waterproof electrical connector is comprised of a male connector housing and the female connector housing. The male connector housing has an annular enclosure around an outer periphery thereof to form an annular cavity therebetween. A seal ring is inserted into the annular cavity. The above-mentioned seal ring has a first section of smaller wall thickness to leave a space, when inserted into the cavity, forwardly opening and a second section of larger wall thickness extending rearwardly of said first section to resiliently press fit the annular enclosure, the end wall and the outer periphery. The female connector housing has a sleeve formed forwardly of an outer periphery thereof and adapted to be inserted into said space. Due to the existence of the second section of larger wall thickness in the seal ring, the turning over thereof which takes place at the time of engaging and disengaging the prior art waterproof connector is prevented.
