Patent ID: 7806725

Claim:
A tool-free coaxial connector for installing on a coaxial cable without the need of using any tool and allowing the coaxial cable to mechanically and electrically connect to a corresponding connector on an electronic device, the coaxial cable including a central conductor, a insulating spacer surrounding the central conductor, at least one layer of braided metal sheath surrounding the insulating spacer, and an insulating sheath surrounding the braided metal sheath; the coaxial connector comprising: an inner sleeve having an outward flange on an end section and an outer sleeve coaxially located around the inner sleeve with an annular hollow space left between the inner and the outer sleeve; the inner sleeve being adapted to receive the central conductor and the insulating spacer of the coaxial cable therein, the outer sleeve being adapted to receive the braided metal sheath and the insulating sheath therein, and the inner sleeve being rearward movable from a first position to a second position in the outer sleeve; an annular tooth being provided around an inner wall surface of the inner sleeve at a predetermined position thereof; and a collar located between the inner sleeve and the outer sleeve adaptable to abut said outer flange of inner sleeve when said coaxial cable is displaced in a rearward direction; whereby when installing the coaxial connector on the coaxial cable by inserting a stripped free end of the coaxial cable into the coaxial connector via a rear open end of the outer sleeve, the inner sleeve is forced between the insulating spacer and the braided metal sheath, and the annular tooth around the inner wall surface of the inner sleeve is tightly engaged with the insulating spacer; and when the coaxial cable is rearwardly displaced, the inner sleeve is simultaneously rearward displaced from the first position to the second position where said outward flange of the inner sleeve abuts an outward flange of the collar, thereby terminating the rearward movement of the inner sleeve.
