Rubber plug null for waterproof connector

摘要

PROBLEM TO BE SOLVED: To provide a rubber plug which reliably seals terminal housing chambers of a connector housing in spite of the simple structure, never springs out to the outside, and has excellent property. ;SOLUTION: This rubber plug 10 comprises a cylindrical main body part 11 and projected streaks 12 for sealing which are closely attachable to the inner wall faces of terminal insertion holes of hollow cavities. Each of the projected streaks 12 for sealing comprises a circular part 13 projected along the outer circumference of the main body part 11 and a thick wall part 14 having a thicker thickness in the axial direction than the circular part 13. Thick wall parts 14 are so made as to have the same projected height as the circular parts 13 and as to be semi-circular smoothly continuous from the side face of the circular part 13 and the parts 14 are projected in the outer circumferential faces of the circular parts 13 at equal intervals.;COPYRIGHT: (C)1998,JPO
