摘要： A clip member is configured for selective engagement with a receiving member having an aperture and a predetermined material thickness between a front surface and a back surface. The clip member includes a base surface and pair of substantially parallel tangs projecting outwardly from the base surface with each tang having an engaging barb. A pair of cantilevered spring tabs are adjacent the tangs and extend from the base surface substantially parallel thereto. The spring tabs have a tab engaging surface projecting above the base surface defining a distance to a barb engagement surface less than the thickness of the receiving member. When the clip member is pressed into the aperture, the tangs are bent as they enter through the front surface. The tab engaging surfaces engage the front surface of the receiving member before the barb engagement surfaces reach the rear surface. The spring tabs deflect with further movement of the clip member into the receiving member and develop a spring load therebetween. The tangs snap back and the barb engagement surfaces engage the rear surface when the barbs exit the aperture, thereby positively retaining the receiving member and maintaining the spring load between the clip member and the receiving member.

摘要翻译： 夹子构件被配置为与在前表面和后表面之间具有孔和预定材料厚度的接收构件选择性地接合。 夹子构件包括基部表面和从基部表面向外突出的一对基本上平行的柄脚，每个柄脚具有接合倒钩。 一对悬臂弹簧片与柄脚相邻并且从底座表面基本平行延伸。 弹簧突片具有突出部接合表面，该突出部接合表面突出在基部表面上方，限定距离接合构件的厚度的倒钩接合表面的距离。 当夹子构件被压入孔中时，柄脚通过前表面而弯曲。 突出部接合表面在倒钩接合表面到达后表面之前接合接收构件的前表面。 弹簧片随着夹构件进一步移动到接收构件中并在其间形成弹簧载荷而偏转。 当倒钩离开孔口时，柄脚回弹，并且倒钩接合表面接合后表面，从而可靠地保持接收构件并将弹簧负载保持在夹子构件和接收构件之间。
