Patent ID: 7477065

Claim:
A probe pin assembly comprising a plurality of elastic probes in a row, each of the elastic probes having a first end portion, at least an elastic bending portion, and a second end portion, the elastic bending portions connecting the corresponding first end portions and the corresponding second end portions, the first end portions formed on a first flat plane, the second end portions formed on a second flat plane, the first flat plane and the second flat plane being parallel or coplanar, the elastic bending portions being not parallel to the first flat plane nor the second flat plane, an upper surface of each of the elastic bending portions beginning at the first flat plane and ending at the second flat plane, wherein the first end portions are inserted into a plurality of connecting holes in a horizontal surface of a probe head in a manner that the second end portions are vertical with respect to the horizontal surface of the probe head to generate a penetrating shifting direction of the elastic probes approximately perpendicular to the arranging direction of the elastic probes.
