Stable-signal connector

The invention relates to the technical field of connectors, and particularly relates to a stable-signal connector which comprises a plastic seat, a metal outer cylinder inserted in the plastic seat, an insulating seat arranged in the metal outer cylinder and a metal terminal assembled in the insulating seat. A pawl spring of the metal terminal is separated from a metal sleeve, the pawl spring is assembled in the metal sleeve, the pawl spring and the metal sleeve are in interference fit to form hard interference, and the hard interference enables a larger positive force to be generated between the metal sleeve and the pawl spring so that the pawl spring can be fixed, the stress of the elastic sheet on the external connection terminal can be increased through the positive force generated by the hard interference, the connection stability of the external connection terminal is improved, and the stability of electric contact between the elastic sheet and the external connection terminal is increased. Therefore, w
