  • Patent number: 5823257
    Abstract: A rotatable wet connect for downhole logging devices. A male shaft is disposed downhole within a drill string. A contact rod of an electrically conducting material having a prong at its uphole end extends through the male shaft, the contact rod electrically insulated from the male shaft. The contact rod electrically connects to a downhole logging device. A shoulder is disposed about a lower portion of the male shaft. A circumferential groove containing a multitude of ball bearings extends about the male shaft adjacent the uphole side of the shoulder. A collar is disposed over the male shaft and rests atop and retains the ball bearings. Set screws retain the collar in place on the male shaft. Once in place atop the ball bearings, the collar may rotate freely about the male shaft. A female sleeve carries a spring biased disc for making electrical contact with the prong of the male shaft. The disc is electrically coupled to the spring, which in turn is electrically coupled to the wireline.
