The invention discloses a probe detector for detecting transverse defects in a rail head. The probe detector is arranged on a detection frame, and comprises a wear-resistant block at the lower portion and a probe box at the upper portion, wherein one side of the probe box is provided with a plurality of mounting grooves, the mounting grooves are provided with fixing keys, a water inlet hole, a plurality of BD probe holes and a plurality of transverse wave probe holes are sequentially formed in the upper surface of the probe box in a penetrating mode, and a water inlet pipe, BD probes and transverse wave probes are installed on the water inlet hole, the BD probe holes and the transverse wave probe holes respectively. According to the invention, the BD probes of the probe detector are arranged in the shape of a Chinese character pin instead of being arranged in a linear mode, two transverse wave probes are additionally arranged, arranged in the longitudinal direction of the steel rail and used for detecting tra
