Document Type and Number:
Japanese Patent JP6432017
Kind Code:
B2
Abstract:
A contact terminal defined by a probe Pr includes a tubular body Pa which is made of an electrically conductive material and is tubular and central conductors Pb and Pc each of which is made of an electrically conductive material and is a shape of a stick. The central conductors Pb and Pc include stick-shaped bodies Pb1 and Pc1 inserted into the tubular body Pa. The tubular body Pa includes spring portions Pe1 and Pe2 which are defined by helical bodies configured such that helical grooves Pg1 and Pg2 are formed along a circumference thereof and clasping portions Pd1 and Pd2 which are fitted onto proximal end portions of the stick-shaped bodies Pb1 and Pc1 to fit the proximal end portions. The clasping portions Pd1 and Pd2 are defined by a circumferential wall of the tubular body Pa by a slit Ph1 extending from end portions of the helical grooves Pg1 and Pg2 which define the spring portions Pe1 and Pe2 in an axial direction of the tubular body Pa at which portions are separated in a circumferential direction of the tubular body Pa.
