PROBE AND SOCKET FOR INSPECTION

To provide a probe and a socket for inspection with which the probe is directly contacted with a housing, and high dimensional accuracy is not required in manufacturing.SOLUTION: Provided is a probe for ground which is formed in a housing 11 and inserted into an open hole 40 defined by a metal inner circumferential wall, comprising a probe body 101 having a cylindrical barrel 130 and plungers 110, 120 extending in the direction of a first axis, and a spring member 150 through which the barrel 130 is inserted. The spring member 150 has a coil part 151 which is wound around a second axis, and through which the barrel 130 is inserted in the direction of the second axis, and a projection part 152 which is formed continuously with the coil part 151 and projects outside of the outer circumferential surface of the coil part 151, elastically contacting the inner circumferential wall, the coil part 151 pushing the probe body 101 against the inner circumferential wall by elasticity of the projection part 152.SELECTED DRAWING: Figure 2 【課題】プローブを直接的にハウジングに接触させるとともに、製造において高い寸法精度が要求されないプローブ及び検査用ソケットを提供する。【解決手段】ハウジング１１に形成されるとともに金属製の内周壁で画定された貫通孔４０に挿通されるグランド用のプローブであって、第１軸線の方向に延在した筒状のバレル１３０及びプランジャ１１０，１２０を有するプローブ本体１０１と、バレル１３０が挿通されるバネ部材１５０と、を備え、バネ部材１５０は、第２軸線の周りに巻回され第２軸線の方向にバレル１３０が挿通されるコイル部１５１、及び、コイル部１５１と連続的に形成されるとともにコイル部１５１の外周面よりも外側に突出して内周壁に弾性を持って接触する突起部１５２を有して、コイル部１５１は、突起部１５２の弾性によってプローブ本体１０１を内周壁に押し付ける。【選択図】図２
