Description
Technical field
A kind of plug using non-jackscrew anti-rotation is the utility model is related to, belongs to downhole instrument cable plug anti-rotation skill
Art field.
Background technology
Oilfield test oil well liquid level majority uses automonitor, and pressure transmitter is to pass through used by this monitor
Plug is connected with socket, there is leader cable on plug.Cable is fixed on wellhead assembly with one side geometrical clamp, if wellhead assembly has
Shake will drive plug to rotate, and be broken off once rotating the wire that may result on core assembly, so as to influence oil field
To the conventionally test of oil well casing pressure.In order to prevent plug from being rotated in the dither process of wellhead assembly, prior art is to adopt
Plug is fixed with jackscrew, the assembling of prior art plug is cumbersome, and field maintenance inconvenience, jackscrew is often lost, and influences electrical cables
The reliability of plug connection.
Utility model content
The purpose of this utility model is, there is provided a kind of plug using non-jackscrew anti-rotation.It is numerous to solve plug assembling
Trivial, field maintenance is inconvenient and jackscrew failure or the problem of lose.
The technical solution of the utility model：
A kind of plug construction using non-jackscrew anti-rotation, including core assembly, nut and tail-hood, core assembly include core
Pipe, core pipe is interior to be provided with insulated column, and contact pin is inlaid with insulated column；The cylindrical step cylinder for intermediate projections of core pipe, step circles
Cylinder is provided with major diameter external screw thread, and major diameter external screw thread is threadedly coupled with nut；The cylindrical of core pipe tail end is provided with minor diameter
External screw thread, minor diameter external screw thread are threadedly coupled with tail-hood.
In foregoing plug construction, the externally threaded rotation direction of major diameter is consistent with thread rotary orientation on socket, the outer spiral shell of minor diameter
The rotation direction of line is externally threaded oppositely oriented with major diameter.
In foregoing plug construction, the tail-hood is provided with wire hole, and tail-hood is coniform close to wire hole one end, and remaining is
Circular tube shaped, the cylindrical of pipe are provided with anti-slip veins, and the inner circle of pipe is provided with the internal thread being connected with core assembly.
In foregoing plug construction, the nut is circular tube shaped, and the cylindrical of pipe is provided with anti-skidding raised line, and the inner circle of pipe is provided with
The internal thread being connected with core assembly.
In foregoing plug construction, the nut, tail-hood and core pipe are aluminum casting.
Compared with prior art, the utility model to the existing improvement with jackscrew plug construction, the utility model by existing
Tail-hood and core assembly need to only be tightened during installation, jackscrew failure can not occur again or lose problem, so as to the scene of reducing
Application risk, improve assembling product efficiency and solve the problems, such as that plug assembles cumbersome and field maintenance inconvenience.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restrictions of type.
A kind of plug construction using non-jackscrew anti-rotation, as shown in figures 1 to 6.Including core assembly 1, nut 2 and tail-hood
3, core assembly 1 includes core pipe 4, is provided with insulated column 5 in core pipe 4, contact pin 6 is inlaid with insulated column 5；Core pipe 4 is cylindrical for centre
Raised step cylinder, step cylinder are provided with major diameter external screw thread 7, and major diameter external screw thread 7 is threadedly coupled with nut 2；
The cylindrical of the tail end of core pipe 4 is provided with minor diameter external screw thread 8, and minor diameter external screw thread 8 is threadedly coupled with tail-hood 3.Major diameter external screw thread 7
Rotation direction it is consistent with thread rotary orientation on socket, the rotation direction of minor diameter external screw thread 8 is oppositely oriented with major diameter external screw thread 7.Tail-hood 3
Be provided with wire hole 9, tail-hood 3 is coniform close to the one end of wire hole 9, and remaining is circular tube shaped, pipe it is cylindrical provided with anti-skidding
Line 10, the inner circle of pipe are provided with the internal thread 11 being connected with core assembly 1.Nut 2 is circular tube shaped, and cylindrical be provided with of pipe is prevented
Sliding raised line 12, the inner circle of pipe are provided with the internal thread 11 being connected with core assembly 1.Nut 2, tail-hood 3 and core pipe 4 are cast aluminium
Part.
Embodiment
This example is the improvement to the existing plug construction with jackscrew, during specific implementation as shown in figures 1 to 6, first will in a pre-installation
The leader cable welded on core assembly 1 passes through nut 2 and tail-hood 3, must go to its internal thread rotation when installing nut 2
Bottom does not have threaded position, then the counter clockwise direction of tail-hood 3 is screwed into bottom locking, to prevent tail-hood 3 from being rotated with cable, this utilization
Internal and external threads are screwed to bottom locking on tail-hood 3 and core assembly 1, more more convenient than being fixed with jackscrew, and solve well
Plug assembles the problem of cumbersome and field maintenance inconvenience.
