ABSTRACT:
A waterproof connector in which, even if tension caused by the bending of an electrical wire is applied to a sealing portion, the waterproofness of the sealing portion is improved without making the dimension and weight of a connector housing larger and heavier. The waterproof connector (A) according to the present invention comprises: a housing (B), a plurality of terminal accommodating cavities (1) in the housing (B), a waterproof plug (5) with a plurality of sealing through holes (7) at positions corresponding to those of the plurality of terminal accommodating cavities (1), a plug cover (6) integrally formed with the waterproof plug (5) to form a sealing portion (C) in combination with the waterproof plug (5). The plug cover (6) is arranged to be mounted to the housing (B), and has a plurality of through holes (8) at positions corresponding to those of the plurality of sealing through holes (7) of the waterproof plug (5). The waterproof connector (A) according to the present invention also comprises an electrical wire-sustaining portion (10) with resilience on an inner peripheral surface of each of the through holes (8) of the plug cover (5). Each wire-sustaining portion (10) may also include water extraction holes (12) and peripheral projections (11) which project in each of the through holes (8) of the plug cover (6) on their inner peripheral surface. Latches (15, 14) for holding the sealing portion (C) in a preliminary state may be used.
