Embodiment
The utility model will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of oil pipe inner cable engaging tool, including pin end and female joint, pin end is by upper end cable 1
Suspension, by the gravity tripping in of weighted lever 3.Pin end lower contact 6 can protect pin end to prevent from being collided with during tripping in, with
The collective effect of centralizer 2 assists pin end to align female joint.The outside O-ring of pin end dead ring 4 can filter mother before docking and connect
Spot on head, O-ring coordinates after isolation docking pin end conducting ring annular space about 5 inside and outside pin end dead ring 4, it is ensured that circuit leads to
Freely, short circuit is prevented.Pin end conducting ring 5 can transmit electric current and electric signal after being matched with female joint conducting ring 10.
As shown in Figure 2, before tripping in female joint, end cable under female joint 15 is accessed into automatically controlled instrument, by snap joint 13
Dismantle, first by after the lower end pin thread access connection automatically controlled instrument in bottom of female joint lower contact 14, will be connect under snap joint 13, female joint
First 14 take back female joint.Female joint top can connect oil pipe 7 or automatically controlled instrument, and pin end is hung in tripping in oil pipe 7 by upper end cable 1
