Patent ID: 8177584

Claim:
A fluidproof connector, comprising: a housing formed with opposite front and rear ends and at least one cavity extending between the ends for accommodating at least one terminal fitting; a wire insertion tube integral or unitary to the rear end of the housing and through which at least one wire connected with the terminal fitting is inserted, the wire insertion tube having a rear end rearward of the housing and at least one engaging recess formed in an inner circumferential surface of the wire insertion tube at a position forward of the rear end of the wire insertion tube, at least one guide groove formed in the inner circumferential surface of the wire insertion tube and extending from the rear end of the wire insertion tube to the engaging recess; at least one resilient plug mounted on the wire and having an outer cross-sectional dimension greater than an inner cross-sectional dimension of the wire insertion tube at locations forward of the engaging recess and at least as great as cross-sectional dimension of the wire insertion tube at the guide groove, so that the resilient plug achieves fluid-tight sealing between an outer circumferential surface of the wire and an inner circumferential surface of the wire insertion tube; a plug retainer mounted into the wire insertion tube at a side of the resilient plug substantially opposite to the cavity, at least one engaging projection projecting from the outer circumferential surface of the plug retainer and engaging the engaging recess; and the engaging recess having at least one opening edge extending in a direction intersecting a longitudinal direction of the wire insertion tube, the opening edge of the engaging recess being formed with a rounded edge at the inner circumferential surface of the wire insertion tube, the rounded edge guiding the resilient plug forward in the wire insertion tube beyond the engaging recess without damaging the resilient plug.
