Abstract
Abstract A waterproof electric connector is provided which renders an inserting operation easy by incorporating waterproof plugs into a connector housing. It includes a connector housing having a plurality of terminal-accommodating cylinders and a waterproof plug retaining member having terminal-inserting openings corresponding to the terminal-accommodating cylinders. Waterproof plugs are engaged with and fixed by the waterproof plug retaining member. Terminals connected to electric wires are inserted into the waterproof plugs through the terminal-inserting openings. The waterproof plugs are mated tightly with the inner surfaces of the terminal-accommodating cylinders.
