In order to form it, it is necessary to punch out a conductive and elastic contact strip-shaped member using punching dies 10, 11 as shown in FIG. For this reason, the contact piece 2
As shown in the cross-sectional view in which a part is enlarged, a burr b having a sharp projection downward is rounded upward on the opposite side. As shown in FIG. 11, when the contact piece 2 is formed by forming the contact piece 2 by inclining in parallel in order to impart spring properties and make multipoint contact, the lower burr portion of the sharp projection becomes the lower contact point. That is, FIG. 12 shows an enlarged part of the state where the contact piece 2 is inserted between the socket A and the plug B. Plug B is inserted, ready shown by a solid line from the state contact piece 2 is shown by a broken line, the height becomes h1 from h, the contact piece 2 is rotated as shown by an arrow E, socket A and a plug B will slide on the contact surface. At this time, having the sharp burr b on the lower side of the contact piece 2 causes the silver plating or the like applied for the purpose of reducing the contact resistance on the contact surface of the plug B to be peeled off, and the electrical contact portion Serious defects will occur which will increase the resistance. The arrow i indicates the direction of the current flowing from the socket A to the plug B.
