Abstract:
A sealing plug for a watertight connector, into which at least one wire is insertable, said wire having an outer surface and having a terminal fitting secured to its end the terminal fitting having a plurality of corners projecting outwardly beyond the outer surface of the wire, the plug being formed with opposite front and rear surfaces, an outer peripheral surface extending between the front and rear surfaces, at least one insertion hole with an inner surface extending between the front and rear surfaces of the plug, the inner surface of the insertion hole including a cross-sectionally round portion at a location spaced between the front and rear surfaces of the plug, the cross-sectionally round portion being sufficiently engageable with the outer surface of the wire to substantially prevent the intrusion of water, a plurality of slits equal in number to the plurality of corners, the slits being formed in the plug and extending from the inner surface of the insertion hole to a location between the insertion hole and the outer peripheral surface, the slits extending continuously from the front surface of the sealing plug to the rear surface and being formed in positions corresponding to the corners of the terminal fitting, such that portions of the sealing plug adjacent the slits deform to permit passage of the corners of the terminal fitting and resiliently return to an undeformed condition for sealed engagement with the wire.
