连接井下仪器短节的连接装置、公接头及母接头
摘要：
本发明公开了一种连接井下仪器短节的连接装置、公接头及母接头，克服目前石油井下仪器的电气连接较为困难的不足。该公接头包括公导电环（10）、公接头本体（13）以及第二电接头（15），第二电接头（15）设置在公接头本体（13）第二端的台阶面上；公导电环（10）绝缘设置在公接头本体（13）中部的外表面。该母接头包括第一电接头（4）、母接头本体（7）以及母导电环（9），第一电接头（4）设置在母接头本体（7）第一端的台阶面上，母导电环（9）绝缘设置在母接头本体（7）中部的内表面。本发明实施例的连接装置可在连接钻铤螺纹的同时同步完成电气的连接。
摘要（英）：

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.
