5results about How to "Stretch out smoothly" patented technology

The utility model relates to a probe module and a detection device. The probe module comprises a first probe die, a second probe die, a first connecting piece, a first elastic piece, a first connecting module and a probe. The first needle die is movably connected to the second needle die through a first connecting piece, and the first needle die can move from a first position far away from the second needle die to a second position close to the second needle die; the first needle die is provided with a first needle hole, and the probe is connected to the second needle die through the first connecting module; when the first needle die is located at the first position, the probe does not protrude out of the surface, deviating from the second needle die, of the first needle die; when the first needle die is located at the second position, the probe protrudes out of the surface, deviating from the second needle die, of the first needle die from the first needle hole; the first elastic piece is connected between the first needle die and the second needle die and used for enabling the first needle die to be reset to the first position from the second position. In this way, the probe can be protected by the first probe die, the probe is prevented from being collided and damaged by foreign objects, and the probe can abut against the circuit board to be tested.
