Document Type and Number:
WIPO Patent Application WO/2023/032625
Kind Code:
A1
Abstract:
Provided are a probe and inspection socket that make it possible for the probe to be brought into direct contact with a housing without a high degree of manufacturing dimension precision being required. This probe for grounding is inserted into a through hole (40) that is formed in a housing (11) and is demarcated by a metal inner circumferential wall. The probe comprises a probe body (101) comprising a cylindrical barrel (130) and a plunger (110, 120) that extend in the direction of a first axis and a spring member (150) that the barrel (130) is inserted into. The spring member (150) comprises a coil part (151) that is wound around a second axis and has the barrel (130) inserted therein in the direction of the second axis and a protrusion part (152) that is formed so as to be continuous with the coil part (151), protrudes further to the outside than the outer circumferential surface of the coil part (151), and elastically touches the inner circumferential wall. The coil part (151) pushes the probe body (101) against the inner circumferential wall as a result of the elasticity of the protrusion part (152).
