Patent ID: 7357659

Claim:
A connector having a male plug comprising a male plug shell which is formed in an approximately tube shape and has a rotatable steel ball, which is able to rotate and move in radial direction, near its opening part and a female plug comprising a female plug shell which is formed in an approximately tube shape and is connected to said male plug shell and connected to a line which transmits electric power, electric signal, and optical signal, comprising: an approximately tube slide sleeve which presses the rotatable steel ball installed around the opening part of said male plug shell from a periphery of said opening part to a centripetal direction; a spring which presses back said slide sleeve along a central axis of said female plug shell until said slide sleeve presses said steel ball to said centripetal direction; and an approximately tube slide cover which comprises the slide sleeve and slides said slide sleeve against elastic force of said spring along the central axis, wherein a first projection part which engages said slide sleeve and a contacting part to which said steel ball can contact while said slide sleeve is pressing said steel ball to said centripetal direction are formed on a surface of a side wall of said female plug shell, said slide cover comprises a second projection part in order to constrain relative rotation of said slide cover and said female plug shell around the central axis, said slide cover can slide to said female plug shell by caulking an approximately ring shape end part of its bottom part placed at an opposite side of its opening part inward, and said slide sleeve engages said first projection part comprised in said female plug shell, said slide sleeve comprises a first concave part which guides said first projection part so that it can slide in the central axis direction and a second concave part which guides said second projection part so that it can slide in the central axis direction.
