Detection device and probe module thereof

The invention discloses a detection device and a probe module thereof, an electrical connection path between a battery detection rack and a battery to be detected is provided through the probe module, and the probe module comprises a seat body, a first polar sheet body, a second polar sheet body, a first upper connection group, a second upper connection group, a first lower connection piece and a second lower connection piece. Through the first polar sheet body, the first upper connecting group is correspondingly coupled with the battery detection rack, and the first lower connecting piece is correspondingly coupled with the battery to be detected; and through the second polar sheet body, the second upper connecting group is correspondingly coupled with the battery detection rack, and the second lower connecting piece is correspondingly coupled with the battery to be detected. Thus, when the probe module is replaced, the cable fixed on the battery detection rack does not need to be processed. In addition, eac
