Abstract:
1. A connector including: a connector terminal projecting from the interior of a case to the exterior of said case through a wall of said case; a first cylindrical wall projecting outwardly from said case wall in surrounding relation to said connector terminals; a seal member mounted within said first cylindrical wall to seal a gap between each of said connector terminals and said case wall; a seal member holder of a cylindrical shape which is fixedly fitted on an outer periphery of said first cylindrical wall at its proximal end-side second cylindrical wall, with its distal end-side third cylindrical wall projecting toward a mating connector, and holds said seal member against withdrawal; a plurality of groove-like notches formed in said second cylindrical wall at intervals in a circumferential direction thereof and extending axially from an end edge of said second cylindrical wall; a first engagement portion formed at said second cylindrical wall in spaced-apart relation to the end edge thereof; and a second engagement portion which is formed at the outer periphery of said first cylindrical wall, and is engaged with said first engagement portion by utilizing elastic deformation of said second cylindrical wall, thereby retaining said seal member holder against movement in the axial direction; wherein a housing of said mating connector is fixedly fitted on an outer periphery of said third cylindrical wall, with a distal end portion of said housing fitted on an outer periphery of said second cylindrical wall of said seal member holder; one of said plurality of notches formed in said second cylindrical wall is larger in width than the other notches; and a positioning rib is formed on and projects from the outer periphery of said first cylindrical wall, and can be properly fitted only in said one notch of a larger width so as to position said seal member holder in the circumferential direction, and when said positioning rib is fitted into any of said other notches, said positioning rib interferes wall portions of said second cylindrical wall disposed respectively at opposite sides of said notch to bulge part of said second cylindrical wall outwardly.
