The invention discloses a connecting device, a male connector and a female connector for joining underground instrument nipples, which overcome the defect that the electrical connection of petroleum down-hole instruments is difficult. The male connector comprises a male conductive ring (10), a male connector main body (13) and a second electric connector (15), wherein the second electric connector (15) is arranged on a second end step surface of the male connector main body (13); and the male conductive ring (10) is arranged on the outer surface on the middle part of the male connector main body (13) in an insulation way. The female connector comprises a first electric connector (4), a female connector main body (7) and a female conductive ring (9), wherein the first electric connector (4) is arranged on a first end step surface of the female connector main body (7), and the female conductive ring (9) is arranged on the inner surface on the middle part of the female connector main body (7) in an insulation way. The connecting device of the embodiment can synchronously complete the electrical connection when being connected with threads of a drill collar.
Description
technical field [0001] The invention relates to the connection technology of petroleum downhole instruments, in particular to a connection device for connecting subsections of downhole instruments and a male joint and a female joint in the connection device. Background technique [0002] In petroleum downhole instruments, there are often great difficulties in the electrical connection between various instruments, because the electrical connection must be completed while the drill collar thread is connected, and the two connections must be synchronized. In order to ensure that the contact between the various electrical components must be reliable, it is also required to seal the electrical joints. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the disadvantage that the electrical connection of the current petroleum downhole instrument is relatively difficult. [0004] In order to solve the above-mentioned technical pro...
