Test fixture and single tail returns shape probe thereof

The utility model discloses a single tail returns the shape probe, including a basal portion, a first cantilever, a second cantilever and a contact arm, first cantilever extends from the one end of basal portion, and it is used for contacting the trial production article that await measuring, the second cantilever extends from the other end of basal portion, and second cantilever, first cantilever lie in same one side of basal portion, the contact arm is protruding locates the one end of keeping away from the basal portion of second cantilever, its printed circuit board who is used for the contact test anchor clamps, and contact arm and printed circuit board be when contacting, contact arm perpendicular to printed circuit board. This list tail returns the shape probe and compares with current equal material, the probe of close price, and resistant electric current ability is with frequency of operation is higher, impedance and signal distortion are lower, it is more stable to test efficiency.
