Abstract: A probe needle includes a head, a tail and a body connected between the head and the tail and provided with a first flat section curvedly extending from the head towards the tail for providing sufficient deformation when the tail is pressed on a device under test, and a second flat section neighbored to the first flat section for supporting the probe needle in between upper and lower dies. When the probe needles are used in a probe module, the probe needles can be arranged with a pitch same as that of the conventional probe needles even though the probe needles are formed from posts having a relatively greater diameter than that of the posts for making the conventional probe needles, such that the probe needles may have enhanced current withstanding capacity and prolonged lifespan.

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.
