Title:
防水コネクタ用シール部材
Document Type and Number:
Japanese Patent JP4200930
Kind Code:
B2
Abstract:
An object of the present invention is to enable a sealing member to be smoothly inserted into a recessed portion while increasing a sealing force.A dummy plug 20 is formed with only one lip 25 having a wide planar top surface 26. Inclined surfaces 27 having a moderate downward inclination are formed at the opposite sides of the top surface 26, and an undulated surface 30 having repeated projections 31 having a short height is formed in the top surface 26. The dummy plug 20 is centered by being guided by the inclined surface 27 and is inserted into a cavity 11 while the wide top surface 26 of the single lip 25 is uniformly resiliently compressed over the entire circumference, whereupon the top surface 26 is held in close contact with the inner circumferential surface of the cavity 11 by the action of a resilient force, thereby sealing the cavity 11. Since the top surface 26 is formed with the fine undulated surface 30, a frictional resistance decreases and an area of contact also decreases. Thus, the dummy plug 20 can be smoothly inserted into the cavity 11 with a smaller force.
