ABSTRACT:
A waterproof connector is provided in which a waterproof packing can be secured quickly and easily to create a water tight seal. The waterproof packing is formed into a frusto-conical configuration and an inner diameter of a rear end thereof is larger than an outer diameter of at least a front end of an inner tubular portion of a female connector housing. The female connector housing includes an outer tubular portion and an inner tubular portion, and terminal receiving chambers are formed in the inner tubular portion. Retaining pawls are formed on an inner surface of the outer tubular portion at a rear end thereof, and openings are formed adjacent to the respective retaining pawls. The outer surface of the inner tubular portion is tapered and decreases in diameter toward the front end thereof, and the waterproof packing is fitted on this outer surface. With this construction, the fitting and securing of the waterproof packing on the inner tubular portion can be effected easily. Also, a front end portion of a male connector housing can be inserted into a gap formed between the outer surface of the waterproof packing and the inner surface of the outer tubular portion so that an electrical connection is made in the waterproof connector.
