  • Patent number: 8087948
    Abstract: A connector housing that is reduced in size in correspondence with reduction in size of a terminal. When a connecting terminal to which an electric wire and a waterproof sealing member are attached is inserted into a terminal accommodating hole from an terminal insertion opening, a step of the waterproof sealing member abuts against a step of the terminal insertion opening and also a taper surface meets a taper surface, preventing water from entering the terminal accommodating hole from the backside. In this state, the waterproof sealing member is pressed toward a connector housing by a rear holder to prevent the waterproof sealing member from falling out of position. Thus, because the terminal insertion opening is sealed, with a part of the waterproof sealing member placed outside the connector housing, the lateral width and vertical width of the terminal accommodating hole can be set to the magnitudes that substantially allow the connecting terminal to pass through the hole.
