Abstract: A probe card includes a probe seat having upper and lower dies and a probe accommodating hole, a spring probe inserted through the probe accommodating hole and including a spring sleeve having upper and lower non-spring sections, and a circuit board disposed on the upper die and having a contact pad against which the spring probe is abutted. At least one of the upper and lower dies has a stopping surface partially facing the probe accommodating hole and an extended portion inserting hole in alignment with the probe accommodating hole. At least one of the upper and lower non-spring sections has a cylinder portion abutted on the stopping surface and an extended portion inserted through the extended portion inserting hole.

Abstract: A probe device includes a spring probe having a spring sleeve with at least a spring section and a connection segment fixed to a needle and having a convex portion protruding over an outer cylinder surface of the spring section, and a probe seat having stacked dies and at least a guiding hole through which the probe is inserted. The dies includes a lower die, a supporting die above the lower die and a non-circular supporting hole at the supporting die. The distance between a supporting surface and a center of the supporting hole is greater than the radius of the outer cylinder surface and smaller than the distance between a guiding surface of the supporting hole and the center, which is greater than the maximum distance between the convex portion and a needle center, thereby preventing the probe receiving external force from exceeding deflection and bending.

Abstract: A spring probe includes a needle, a spring sleeve sleeved onto the needle, and a protrusion. The spring sleeve has upper and lower non-spring sections, and at least a spring section therebetween. The needle has a bottom end portion protruding out from the lower non-spring section, and a top end portion located in the upper non-spring section. The protrusion is located at one of the top end portion and the upper non-spring section. The needle is movable relative to the upper non-spring section from an initial position to a connected position where the upper non-spring section is electrically connected with the needle through the protrusion when receiving an external force. As a result, the spring probe effectively prevents signals from being transmitted through the spring section, thereby improving stability of signal transmission and preventing the spring section from fracture.

Abstract translation: 弹簧探针包括针，套在针上的弹簧套和突起。 弹簧套筒具有上下非弹簧部分，并且至少在其间具有弹簧部分。 针具有从下部非弹簧部分突出的底端部分和位于上部非弹簧部分中的顶端部分。 突起位于顶端部分和上部非弹性部分中的一个处。 针可以相对于上部非弹簧部分从初始位置移动到连接位置，在接收外部力时上部非弹簧部分通过突起与针体电连接。 结果，弹簧探针有效地防止信号通过弹簧部分传递，从而提高信号传输的稳定性并防止弹簧部分断裂。
