Abstract:
A waterproof plug formed from a resilient rubber material for providing sealing between a wire and a wire insertion hole of a housing, the plug, in an unbiased condition, comprising:a trunk, at least a portion of the trunk having a cylindrical outer circumferential surface dimensioned for close contact with an inner circumferential surface of the housing defined by the terminal insertion hole of the housing; a fixing portion extending from an end of the trunk and configured to be fixed to a terminal fitting; and a wire insertion hole formed through the trunk and the fixing portion, at least a section of the wire insertion hole formed through the trunk defining a cylindrical inner circumferential surface with an inner diameter dimensioned for close resilient contact with an outer circumferential surface of the wire, wherein the wire insertion hole in the fixing portion has an inner circumferential surface that tapers gradually at farther distances from the trunk such that an inner diameter of the wire insertion hole in the fixing portion is smaller than the inner diameter in the trunk, and wherein the fixing portion has an outer circumferential surface that tapers gradually at farther distances from the trunk such that an outer diameter defined by the fixing portion is reduced gradually at farther distances from the trunk.
