1. A probe structure for inspecting characteristics of a connector including at least one terminal, the probe structure comprising:
- a plunger that includes a groove portion to which the connector is to be fitted;
a coaxial probe that is inserted into the plunger and that allows a conductor pin to be exposed at a position corresponding to the terminal of the connector that is fitted into the groove portion of the plunger;
a flange that is fixed to an apparatus for inspecting the characteristics at a position that is spaced apart on a side opposite to a side on which the conducting pin is exposed with respect to the plunger, the flange having a through-hole into which the coaxial probe is inserted;
a housing that includes a first end portion and a second end portion and that extends toward the plunger while surrounding the coaxial probe, the first end portion being fitted into the through-hole of the flange from a side opposite to a side on which the plunger is disposed, the second end portion being attached to the plunger; and
a spring that is attached to a portion between the plunger and the flange, that is disposed at a position surrounding the housing, and that urges the plunger in a direction away from the flange,wherein the first end portion of the housing and the through-hole of the flange have outer shapes that restrict rotation of the housing in a circumferential direction in a state in which the first end portion of the housing is fitted into the through-hole of the flange.

Abstract
A probe structure for inspecting characteristics of a connector having at least one terminal includes a plunger, a coaxial probe, a flange, a housing, and a spring. A first end portion of the housing and the flange are configured to restrict rotation of the housing in the circumferential direction in a state in which the first end portion of the housing is fitted into the through-hole of the flange. Thus, inspection of characteristics of the terminal of the connector can be performed with higher accuracy.
