Abstract
For use in drill pipe conveyed logging systems wherein the logging apparatus is enclosed in a housing affixed to the lower end of a drill pipe string, a system is disclosed utilizing a wet connector and overshot. The wet connector includes a centralized upstanding mechanical connector means having a J-slot cooperative with pins inserted thereinto. The J-slot is adjacent to a sleeve which telescopes over an enclosed and protected upwardly facing electrical connector means. On the overshot, the solid body thereof includes a lower appended skirt having inwardly protruding pins which engage the J-slots to achieve a separate mechanical connection. There is internally of the overshot a spring mounted telescoping and movable electrical connector including a cooperative socket engaging the plug of the wet connector. The electrical connection is kept separate from the mechanical connection so that the entire load of operation is carried separately without interfering with operation of the electrical connectors.
