A type of waterproof connector is used in which the above-mentioned endless seal member a is locked onto the inner peripheral surface of the fitting part e of the female connector housing d to isolate it from the outside. shaped seal member a
In order to lock the locking ring f into the fitting opening e, a locking ring f having an axial length shorter than the axial length of the fitting opening e is inserted and locked into the fitting opening e. Since a recessed groove h for interposing the endless upper seal member a is formed between the step part g formed in the fitting opening part e, the shaft of the fitting opening part e is A step is created in the middle of the direction length, and the outer shape of the tip end of the fitting head i of the male connector housing b inserted into the part is approximately the same as the inner diameter of the locking ring f, and the fitting opening part e
When the male and female connector housings d and b are mated, their axes are shifted from each other and their insertion directions do not match, causing the male connector housing b to be inserted into the female connector housing. d
The tab-shaped electrical contact portion l protruding into the insertion opening e of the electrical connector h whose base is housed and locked in the cavity j of the female connector housing d is inserted into the male connector housing b. The axial direction does not match the receptacle-shaped electrical contact part o of the electrical connector n housed in the cavity m of the male connector housing b, and there is a risk that the male connector housing b may come into contact with the surface p along the opening end of the cavity m, resulting in deformation, etc. In order to prevent this, a protrusion r is provided which protrudes beyond the protruding width of the electrical contact l from the surface q along the opening end of the cavity j of the female connector housing d, and a corresponding hole s is provided. The cavity m of the male connector housing b is penetrated from the surface p along the opening end until the protrusion r is fitted into the hole s.
The surface p along the opening end of the cavity m of the male connector housing b is made so that it does not reach the electrical contact portion l of the female connector housing d, and
When the hole s and the hole s are inserted, the electrical contact l
is inserted into the electrical contact part o.

る。(Effects of the Invention) As explained above, the present invention provides sealing performance to the joint portion of the male and female connectors by disposing an endless elastic sealing member serving as a sealing means on the inner circumferential surface of the insertion opening of the female connector housing. In this waterproof connector, in order to guide and restrict the fitting cylinder part of the male connector housing in the fitting part of the female connector housing, there is a hole penetrated from above the surface along the cavity opening end of the fitting part and a hole in the male connector housing. Rather than engaging with a protrusion protruding from the surface along the opening edge of the cavity, the endless elastic seal member is fitted with a slit provided in the locking ring to accommodate and lock the endless elastic seal member within the fitting opening. Since this is done through engagement with the protrusions provided on the male connector housing, there is no need for an area for forming the protrusions and holes, and the width of the male and female connector housings in the shearing direction is minimized. I can do it.

A side wall that is integrally spanned and forms the fitting opening of the female connector housing includes:
Since a cutout corresponding to the bridge protruding from the side wall of the locking ring is provided from the opening end of the insertion opening, the locking ring has structural strength, and the bridge is located inside the cutout. Therefore, the bridge portion does not protrude outward in the overall shape of the housing.
