摘要： A tubular body extending in a longitudinal direction and having conductivity includes a first spring portion having a spiral notch formed in a peripheral surface of the tubular body, a second spring portion having a spiral notch formed in the peripheral surface of the tubular body and a first body portion sandwiched between the first spring portion and the second spring portion in the longitudinal direction. The distance from the longitudinal direction center of the tubular body to the longitudinal direction inner end of the first spring portion is equal to the distance from the longitudinal direction center to the longitudinal direction inner end of the second spring portion. The number of turns of the first spring portion is equal to the number of turns of the second spring portion. The first spring portion includes a first winding spring portion whose winding direction is a first direction and a second winding spring portion whose winding direction is a second direction opposite to the first direction.

摘要： A probe device is mounted on a circuit provided with a holder mountable to a circuit board testing apparatus, a contact needle attachable to the holder. The contact needle is operable to resiliently bend in a specified direction immediately after coming into contact with a circuit board. The bending absorbs a contact impact to ensure accurate measurement.

摘要： [Object] To detect the misalignment of a printed circuit board for which a continuity test is conducted, in a non-contact manner using a simple structure. [Constitution] Position detection electrodes S1 and S2 are disposed so as to be point-symmetrical relative to an arbitrary point px on a line Lx that extends almost along the center of a printed pattern 34a on an opposite circuit board and that is parallel with the Y axis. Position detection electrodes S3 and S4 are disposed in the same manner. A probe selection switch section SW11 can provide a probe selection signal, and a position detection sensor selection switch section SW12 can provide a signal for selecting among the position detection electrodes S1 to S4. A detected voltage varies depending on how the position detection electrode S1 is opposed to a printed pattern 34a. Thus, misalignment can be detected by detecting the opposition relationship between each of the position detection electrodes S1 to S4 and the printed pattern 34a.

摘要： 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.
