PROBE DEVICE HAVING SPRING PROBE |
摘要 |
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. |

1. A probe device comprising:
a spring probe including a needle, and a spring sleeve sleeved onto the needle and having at least one spring section and a connection segment fixed to the needle and provided with a convex portion protruding over an outer cylinder surface of the at least one spring section; and a probe seat including a plurality of dies stacked together, and at least a guiding hole through which the spring probe is inserted; wherein the dies of the probe seat comprise a lower die, and a supporting die located above the lower die; the at least one guiding hole of the probe seat comprises a supporting hole provided in the supporting die with a non-circular profile, and defined with a center, a guiding surface and a supporting surface; a distance between the supporting surface and the center is greater than a radius of the outer cylinder surface of the at least one spring section of the spring sleeve; a distance between the guiding surface and the center is greater than the distance between the supporting surface and the center and greater than a maximum distance between the convex portion and a center of the needle. |
