Coaxial cable connector

A coaxial cable connector for connecting a coaxial cable, said coaxial cable connector is adapted to engage with a connector of an electronic device having a threaded surface, said coaxial cable connector comprising:

• an inner sleeve, comprising a first outer flange, a second outer flange and a first rear-end extension portion, wherein the second outer flange is disposed between the first outer flange and first rear-end extension portion;
• a nut, coaxially arranged with the inner sleeve, comprising a first inner flange and a threaded portion adapted to engage with said threaded surface, wherein the first inner flange is positioned on the second outer flange of the inner sleeve;
• a second inner ring, coaxially arranged with the inner sleeve, wherein the second inner ring comprises a ring portion and a plurality of elastic portions, wherein one end of each of the plurality of elastic portions is respectively connected with said ring, portion, and a first gap is formed between each two adjacent elastic portions of the plurality of elastic portions, and the other end of each of the plurality of elastic portions comprises a fifth outer flange;
• and
• an outer sleeve coaxially arranged with the second inner ring and the inner sleeve, wherein the inner wall of the outer sleeve comprises a fourth inner flange and an engaging bump, wherein the engaging bump is in contact with the outer surface of the second inner ring and is positioned between the fourth inner flange and the fifth outer flange of the second inner ring,
• wherein the ring portion of the second inner ring is positioned between the fifth outer flange of the second inner ring and the fourth inner flange of the outer sleeve, and wherein a first annular space is formed between the ring portion and a part of the first rear-end extension portion of the inner sleeve, and
• wherein when the outer sleeve moves toward the nut, the engaging bump presses the fifth outer flange of the second inner ring so as to enable the fifth outer flange to move toward the outer surface of the inner sleeve.
