Claims

[Claims for Utility Model Registration] 1. An engaging protrusion and a stopper are formed in the opening of a conductive sleeve, and a contact pin is urged to protrude outward by the elasticity of a coil spring and fitted into the sleeve. a helical groove is formed on the outer periphery of the contact pin so as to engage with the engagement protrusion;
A contact probe characterized in that the lead angle of this helical groove is changed from an acute angle to an obtuse angle from the middle. 2. The contact probe according to claim 1, wherein the helical groove has an acute angle at its base, and an obtuse edge at the free end of the helical groove.
