    • A two-piece panel fastener includes a barrel-shaped metal retainer which holds a screw. The screw includes a threaded shaft and a plastic cap which has longitudinally-extending resilient fingers which engage the outer surface of the retainer to captivate the screw. The retainer has a chamfered top flange along its top edge, a circumferential bulge area around its outer surface approximately in the middle of its length, and a base at the bottom. Two circumferential valley regions of reduced diameter are located along the outer surface of the retainer. The first valley region is located between the chamfered top flange and the bulge area and the second is located between the bulge area and the base. When the fingers occupy either of the valley regions, the screw is captively held at either of two stable positions of retraction or extension. The retainer is preferably rigidly affixed to a circuit board by soldering a base flange at the bottom of the retainer to the top surface of the board. After the retainer is separately soldered to the circuit board and the retainer has cooled, the screw and cap assembly are joined to the retainer by snap action of the resilient cap fingers.
    • 两件式面板紧固件包括保持螺钉的桶形金属保持器(10)。 螺钉包括螺纹轴和塑料盖(6),其具有纵向延伸的弹性指(7),其接合保持器的外表面以吸引螺钉。 保持器沿着其顶部边缘具有倒角的顶部凸缘(13),围绕其外表面的大致在其中间的周边的圆周凸起区域(16)和底部的底部(15)。 减小直径的两个圆周谷部区域沿保持器的外表面定位。 第一谷区域位于倒角顶部凸缘和凸起区域之间,第二谷部位于凸起区域和基部之间。 当手指占据任何一个山谷区域时,螺钉被固定地保持在两个稳定的缩回位置或延伸位置。 保持器优选通过将保持器底部的底部凸缘焊接到板的顶表面而刚性地固定到电路板(5)。
