Abstract
Abstract In a packing support arrangement for a waterproof connector in which a annular packing is fitted on an outer peripheral surface of a connector housing, the improvement comprising, support portions formed on the outer peripheral surface of the connector housing for supporting a front end portion of the annular packing, engaging recesses formed on an inner peripheral surface of the annular packing for receiving the support portions, and a reinforcement receptive portion formed at the front end portion of the annular packing and reinforced by the support portions. Accordingly, a smooth fitting relative to a mating connector housing can be maintained, and also deformation of the packing is prevented, thereby attaining a stable sealing purpose.
