Patent ID: 7057403

Claim:
A microcontactor probe comprising: an insulator formed with a support hole having an open end and a close end; a lead conductor exposed inside the support hole at the close end; and a resilient conductive assembly fitted in the support hole and kept from falling, the assembly comprising: a first plunger exposed outside at the open end; a second plunger contacting the lead conductor; and a coil spring fitted on the first and second plungers, the coil spring having a connected tight wound portion fixed to one of the first and second plungers at a fixed part for conductions and the tight wound portion slidably contacting on the other of the first and second plungers so that said other of said first and second plungers is extendable into the tight wound portion and the tight wound portion extending beyond the fixed part to said one of the first and second plungers into a sliding part for conduction, thereby minimize resistance and induction during a probe operation.
