    • A slide fastener slider has body and diamond preferably of molded plastic parts. The parts are held together in snapfastener fashion. Typically, the slider body carries a head and the diamond an opening or socket. Molded integrally with the diamond is an arching locking arm and a pull tab is provided preferably formed of a pair of cords with spaced crosspieces. The tab is provided with an anchoring end adapted to be trapped under inward flanges at the top of the socket opening, one of the crosspieces being disposed under the locking arm to raise the arm during the pulling of the pull tab. The aforementioned anchoring end prevents overtaxing the locking arm, absorbing the pulling force beyond a preset limited amount borne by the arm.
    • 拉链滑块具有最好是模制的塑料部件的主体和金刚石。 部件以卡扣式方式保持在一起。 通常,滑块体将头部和钻石带有开口或插座。 与金刚石一体成型的是拱形锁定臂,并且优选地由具有间隔开的横档的一对帘线形成拉片。 突片设有一个锚固端,适于被困在插座开口的顶部的向内凸缘下方,其中一个挡块设置在锁定臂的下面,以在牵引拉片期间升高臂。 上述锚固端防止锁定臂过载,从而将拉力吸收超过由臂支承的预设限制量。
