Patent ID: 7806726

Claim:
A RF microwave connecter for telecommunication comprising: a metal housing having an upper end extending upward with a coupling portion, a pair of arms extending outward from the metal housing opposite to said coupling portion, a spacing is provided between said two arms, and said coupling portion being provided with a middle element and a plurality of pairs of tabs respectively extending outward from two sides of said middle element; a plastic insulator, which is disposed around an inner side of said metal housing, being provided with a hollow portion, an upper end of said plastic insulator being provided with a bendable sheet extending upward and a projection portion extending outward levelly, said projection portion being accepted between said two arms, said bendable sheet being positioned opposite to said projection portion, said projection portion being provided with grooves, said bendable sheet being corresponding to said grooves, a central terminal engaging with said hollow portion, and an upper end surface of said central terminal being provided with a sheet type connection portion; wherein, said connection portion of said central terminal is positioned in said grooves; said grooves further comprise a first groove and a second groove communicated with each other, a diameter of a cross section of said second groove is larger than a diameter of a cross section of said first groove, and said second groove is positioned above said first groove; said bendable sheet is provided with a first projection portion and a second projection portion respectively corresponding to said first groove and said second groove; whereby, when an inner conducting wire of a coaxial cable is placed on the upper sides of said upper end surface and said connection portion of said central terminal, said connection portion and said bendable sheet are then further allowed to bend to cause said inner conducting wire to be thrust into said grooves and said first projection and said second projection of said bendable sheet to be positioned in said first groove and said second groove respectively to compress the upper side of said inner conducting wire to enable said inner conducting wire and said coupling portion not to contact with each other; in the meantime, the plurality of pairs of tabs respectively buckle said metal housing, said two arms, a ground conductor layer, and an outer insulator layer of said coaxial cable.
