ABSTRACT:
A waterproof electrical connector comprises first and second connectors which are connected to each other. The first connector comprises a first housing in a cylindrical shape having a fitting recess. The second connector comprises a second housing. A sealing member held in a holding groove on the outer periphery of the second housing seals the fitting recess in a state where it is fitted in the fitting recess. The second housing has first and second sections on both sides with the holding groove interposed therebetween. The first section comprises a plurality of cylindrical sections extending along a connector connection direction from a peripheral sidewall adjacent to the holding groove. The cylindrical section comprises guiding sections inserted into the fitting recess prior to inserting the sealing member into the fitting recess for guiding the insertion of the sealing member into the fitting recess.
