Document Type and Number:
WIPO Patent Application WO/2018/101232
Kind Code:
A1
Abstract:
This contact terminal comprising a probe Pr includes: a cylindrical body Pa formed from a conductive material into a cylindrical shape; and center conductors Pb, Pc that are each formed from a conductive material into a rod shape. The center conductors Pb, Pc respectively have rod bodies Pb1, Pc1 that are inserted into the cylindrical body Pa. The cylindrical body Pa has: springs Pe1, Pe2 comprising spiral bodies with spiral grooves Pg1, Pg2 that are provided along the circumferential surface of the cylindrical body Pa; and holding portions Pd1, Pd2 that are externally fitted to the base ends of the rod bodies Pb1, Pc1 so as to respectively hold the rod bodies Pb1, Pc1. The holding portions Pd1, Pd2 comprise a circumferential wall of the cylindrical body Pa, a part of the circumferential wall being segmented in the circumferential direction of the cylindrical body Pa by a slit Ph1 that extends in the axial direction of the cylindrical body from ends of the spiral grooves Pg1, Pg2 constituting the springs Pe1, Pe2.
