PROBLEM TO BE SOLVED: To provide a pushing type spring connector capable of housing a contact pin inside a tube so as to line along an axis center of the tube, always obtaining stable electric characteristics by a touch ring fitted at an outer side face of the contact pin, and being miniaturized. SOLUTION: The contact pin 20 having a space part inside is housed in a space of the tube 10 along the axis center of the tube 10 in free sliding. A spring-like touch ring 30 is fitted on an outer side face of the contact pin 20. A second winding of the touch ring 30 is formed in a larger diameter than a first winding, with the former always in contact with the tube 10 and the latter always in contact with the contact pin 20. A coil spring 40 has its tip housed in the space part of the contact pin, and its base part housed in the tube 10. COPYRIGHT: (C)2004,JPO&NCIPI
