1. A coaxial cable connector for electric connection with an electric wire having a peripheral conductor and a center conductor, the coaxial cable connector comprising:

  • a body including an annular flange formed on an upper portion of an outer periphery thereof, thereby forming a first shoulder at a bottom of the annular flange, the body further including a cylindrical member integrally formed from said body and which extends upwardly from an upper side thereof and which has an axial hole defined therein, the body further including a bore therein having a diameter greater than that of the axial hole, the body further including an annular groove define in a lower portion of the outer periphery thereof;

    a sleeve directly mounted around an outer wall surface of the cylindrical member for securing the peripheral conductor of the electric wire between the cylindrical member and the sleeve;

    a retaining ring securely mounted in the annular groove of the body;

    an upper washer engaged with the first annular shoulder of the body;

    a spring washer biased between the retaining ring and the upper washer for biasing the upper washer to engage with the first annular shoulder of the body;

    a lower washer mounted around the body at a position below the retaining ring;

    a barrel including an annular projection extending radially and inwardly from an upper portion of an inner periphery thereof for engaging with the upper washer, the barrel further including a second annular shoulder formed in a mediate portion of the inner periphery thereof for engaging with the lower washer, the upper washer being moved toward the retaining ring against the resilient ring by moving the barrel for resiliently plugging the coaxial cable connector into a socket member; and

    an insulating collar and an insulating tube mounted in the bore of the body and around the center conductor, the insulating collar being made of ferro-ceramic material for eliminating external electromagnetic interference and radio frequency interference as well as internal undesired signals.
