Abstract
This invention provides a waterproofing assembly for a connector a housing of which is completely waterproofed. A rear rubber plug 39 is press-fitted in a rear cylindrical portion 28 of a housing 20 in which a female terminal metal fixture 30 connected to an electrical wire 38 is accommodated. A cap 50 is mounted on a front cylindrical portion 21 of the housing 20 while a front rubber plug 40 is press-fitted in the front cylindrical portion 21. The front rubber plug 40 has first and second cylindrical portions 41 and 44 and a uniting portion 45 for sealingly coupling the portions 41 and 44. A rib 53 formed in the cap 50 is press-fitted in a clearance 43 in the front rubber plug 40 so that the cap 50 covers the front cylindrical portion 21.
