Abstract: A snap-n-seal connector for coaxial cables includes a connector body, an annular compression sleeve and optionally, a sealing nut. The connector body includes an annular collar member which peripherally engages the jacket of a coaxial cable, a post member coaxially disposed within the annular collar member to engage the dielectric insulation and the braided shield of the coaxial cable, and a rotatable nut member disposed in combination with the collar and post members. The compression sleeve is configured for snap fitting engagement between the jacket of the coaxial cable and the annular collar member to provide a moisture proof circular seal therebetween and to force the braided shield into mechanical and electrical engagement with the contact spring member an/or the post member. The compression sleeve includes a sealing member to provide a 360 degree moisture proof seal between the compression sleeve and the collar member.
