Abstract
A waterproofed connector has an outlet for an electrical cable which is molded by a resin material under a structure which can prevent a mold resin material from entering into terminal metal fixtures. The waterproofed connector includes a connector housing (10) having a cavity (12), terminal metal fixtures (40) each connected to an end of each core wire (22) of an electrical cable (20) and inserted into a terminal opening (131) in the cavity (12), a plug body (50) inserted into the cavity (12) and having a pair of through holes (53) for permitting each core wire (22) to pass through and a mold resin layer (100) formed around a rear end of the connector housing (10). The plug body (50) made of a resilient material contacts firmly with an interior of the opening (131), so that the plug body (50) can prevent the mold resin material from entering into the terminal metal fixtures when molding and also can perform waterproofing even if any clearance is formed between the mold resin layer (100) and the electrical cables (22). The plug body (50) and an accommodating chamber in the cavity (12) may be provided with tapered exterior and interior, respectively, thereby causing a close contact …
