Abstract
Provided is a cable fixed joint of a free point tool. A cable penetrates through a steel joint inner hole, a section of a cable wire of the cable is parted to expose a cable insulation body and a cable conductor, then the cable penetrates through a cable fixed inner sleeve to divide the cable wire into a plurality of filaments, the plurality of filaments are respectively bended and lean against a sawtooth plug of the cable fixed inner sleeve, a cable fixed outer sleeve is pressed on the cable wire and sleeved on the sawtooth plug of the cable fixed inner sleeve, and then the cable fixed inner sleeve is tightened and fixed through a fixed screw.
Description
Affiliated technical field
On the utility model is applied in the oil field downhole instrument and cable is connected, be that a kind of convenient disassembly is quick, the reliable sticking point instrument cable permanent joint of connection.
Background technology
At present, the sticking point instrument cable permanent joint of oil field use is made up of steel joint, hold-down screw, the fixing interior cover of cable and cable fixed jacket.Cable passes the joint endoporus; Push cable aside one section cable wire and expose cable insulation and cable conductor, pass the fixing interior cover of cable to cable again, be divided into multifilament to cable wire; Bending is inserted respectively in the aperture of the fixing interior cover outer shroud of cable; In cable is fixing, put the cable fixed jacket of screwing on, and compress cable wire, with hold-down screw the fixing interior cover screwing of cable is fixed then.The joint box thread connects downhole instrument, and the 48V direct current is transmitted to downhole instrument from aboveground cable through sticking point instrument cable permanent joint.But, because sticking point instrument cable permanent joint goes into the well frequently, need often dismounting, and the cable wire that sticks mud is difficult to extract the aperture of cover outer shroud in fixing, the time that dallies over one's work very much, brings great difficulty and trouble to oil field field operation personnel.
Summary of the invention
In order to overcome the problems such as not only time-consuming but also effort that occur in the existing sticking point instrument cable permanent joint dismounting, the utility model provides a kind of sticking point instrument cable permanent joint, and this sticking point instrument cable permanent joint not only connects reliably, and convenient and swift, and is economical and practical.
The utility model solves the technical scheme that its technical problem adopted: in sticking point instrument cable permanent joint steel joint; The fixing interior cover of cable is processed into wicker stab; Cable fixed jacket inwall is processed into the light face, and the circumferential clearance of cover sawtooth plug and cable fixed jacket inwall equaled the cable wire diameter in cable was fixing.Cable passes the joint endoporus like this; Pass the fixing interior cover of cable again, be divided into multifilament to cable wire, bending leans against on the fixing interior cover sawtooth plug of cable respectively; Be enclosed within cable fixed jacket one end on the fixing interior cover sawtooth plug of cable then; Knock the cable fixed jacket other end lightly with hand hammer, make it compress cable wire and be advanced on the fixing interior cover of the cable fixed position, with hold-down screw the fixing interior cover screwing of cable is fixed then.When the dismounting cable; Only need back out hold-down screw; Insert cable fixed jacket and fixing interior cover seam crossing one sled of cable with screwdriver; Just be easy to put from cable the cable fixed jacket in fixing and prize, cable wire just in cable is fixing on the cover sawtooth plug surface, stretching back just from cable fix interior overlap and joint extracted out.Convenient disassembly is quick like this, has improved operating efficiency.
The beneficial effect of the utility model is that this cable fixed form is simple in structure, does not change the switching performance of sticking point instrument cable permanent joint, and is convenient and swift, economical and practical when making this instrument dismounting cable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sectional structure chart of the utility model.
1. steel joints among the figure, 2. hold-down screw, the 3. fixing interior cover of cable, 4. cable fixed jacket, 5. cable wire, 6. cable insulation, 7. cable conductor.
Embodiment
In Fig. 1; Cable passes steel joint (1) endoporus, pushs cable aside one section cable wire (5) and exposes cable insulation (6) and cable conductor (7), passes the fixing interior cover of cable (3) again; Be divided into multifilament to cable wire (5); Bending leans against fixing interior the overlapping on (3) sawtooth plug of cable respectively, compresses cable wire (5) to cable fixed jacket (4) and is enclosed within on fixing interior cover (3) the sawtooth plug of cable, uses hold-down screw (2) that cable is fixed interior cover (3) then and tightens fixing.Convenient and swift, economical and practical when dismantling cable like this.
