<p>CONTACT PROBE AND SOCKET, AND MANUFACTURING METHOD OF TUBE PLUNGER AND CONTACT PROBEA contact probe has a tube plunger which does not depend on the press working andthe rounding process and which differs from conventional bag-like hollow plunger, so thatquality control of gold plating or the like is not necessary or not difficult. The tubeplunger is made of a tubular metal 20 of which tip part is shaved to be a small outsidediameter and is cut out notches 30 from the tip part. The tip part remained is bent inside, and an outer surface of the tubular metal from the bending part to bottom side is shaved tobe a small diameter so that a convex part 40 of a large diameter is made partly. The part ofthe small diameter of the tubular metal 20 is cut off at the end side edge of the smalldiameter.FIG. 1A to FIG. 1E</p> |
