Abstract: An elongate, columnar micro-mechanical structure disposed along a central longitudinal axis; the structure is made up of laminated structural layers, each comprised of a structural material. The layers define a substantially rigid base portion at a proximal end of the structure, a resilient intermediate portion extending from the base portion along the central axis, and a contact tip extending from the resilient portion at a distal end of the structure. The resilient portion of the contact structure is comprised of resilient arms defined in the layers. Opposite ends of the resilient arms may be angularly offset with respect to one another around the central axis. Accordingly, when the contact structure is compressed in an axial direction, the contact tip will rotate around the central axis, while the base remains fixed, providing beneficial wiping action to the contact tip.

Abstract translation: 沿着中心纵向轴线设置的细长柱状微机械结构; 该结构由层压结构层组成，每层由结构材料构成。 这些层在结构的近端处限定基本上刚性的基部，从基部延伸的弹性中间部分沿着中心轴线，以及在结构的远端处从弹性部分延伸的接触尖端。 接触结构的弹性部分由限定在层中的弹性臂组成。 弹性臂的相对端部可以相对于中心轴线彼此成角度地偏移。 因此，当接触结构沿轴向压缩时，接触尖端将围绕中心轴线旋转，同时基座保持固定，为接触尖端提供有益的擦拭作用。

Abstract: An apparatus and method providing improved interconnection elements and tip structures for effecting pressure connections between terminals of electronic components is described. The tip structure of the present invention has a sharpened blade oriented on the upper surface of the tip structure such that the length of the blade is substantially parallel to the direction of horizontal movement of the tip structure as the tip structure deflects across the terminal of an electronic component. In this manner, the sharpened substantially parallel oriented blade slices cleanly through any non-conductive layer(s) on the surface of the terminal and provides a reliable electrical connection between the interconnection element and the terminal of the electrical component.

Abstract: An elongate, columnar micro-mechanical structure (100) disposed along a central longitudinal axis (101); the structure is made up of laminated structural layers (102, 104, 106), each comprised of a structural material. The layers define a substantially rigid base portion (108) at a proximal end of the structure, a resilient intermediate portion (110) extending from the base portion along the central axis, and a contact tip (112) extending from the resilient portion at a distal end of the structure. The resilient portion of the contact structure is comprised of resilient arms defined in the layers. Opposite ends of the resilient arms may be angularly offset with respect to one another around the central axis. Accordingly, when the contact structure is compressed in an axial direction, the contact tip will rotate around the central axis, while the base remains fixed, providing beneficial wiping action to the contact tip.
