Abstract

PURPOSE:To provide a coaxial plug where a cable holding metal fitting can be easily detached from a cable connecting metal fitting so as to facilitate wire connecting work. CONSTITUTION:Engaging claws 7d, 7d are slidably engaged with engaging holes 5f, 5f so that a cable holding metal fitting 7 is pivoted to a cable connecting metal fitting 5 in a freely opening or closing manner. Locking claws 7e, 7e to be locked to locking holes 5g, 5g formed on operating pieces 5c, 5c of the cable connecting metal fitting 5 are formed on the cable holding metal fitting 7. In a state where the cable holding metal fitting 7 is locked to the cable connecting metal fitting 5, the tip of a spring piece 5d is compressed in abutment against the inside surface of the cable holding metal fitting 7. Consequently, the cable holding metal fitting 7 is elastically energized toward the opening direction by the spring piece 5d. As a result, disengagement of the locking claws 7e, 7e from the locking holes 5g, 5g enables the cable holding metal fitting 7 to resiliently spring upward so as to open by itself.
