Test probe suitable for detecting test points of oxide layer and rosin layer

The invention discloses a test probe suitable for oxide layer rosin layer test point detection, comprising: a needle tube, the inner wall of one port of the needle tube being provided with a guide pin; the elastic piece is arranged in the needle tube; a spiral guide groove is formed in the outer wall of the needle head in the axial direction of the needle head, and the guide pin is arranged in the spiral guide groove. According to the test probe suitable for detecting the test point of the oxide layer and the rosin layer, the problem that a probe head of an existing test probe cannot smoothly penetrate through the test point to form good contact with the test point is solved. 本发明公开了一种适用于氧化层松香层测试点检测的测试探针，包括：针管，所述针管一端口的内壁上设置有导销；弹性件，所述弹性件设置在针管内；针头，所述针头的外壁上延其轴向设置有螺旋状导槽，所述导销布置在所述螺旋状导槽中。该适用于氧化层松香层测试点检测的测试探针，解决了现有测试探针的针头存在无法顺利穿过与测试点接触形成良好接触的问题。
