Abstract
The invention relates to a maintenance-free anti-looseness insulating pup joint. Screw threads of the conventional insulating pup joint possibly loosen due to stress so as to unscrew the screw threads, the measuring effect and insulating effect of an instrument are influenced, and the manufacturing cost is increased due to a complex structure. The pup joint comprises an upper joint part, an insulating part and a lower joint part, wherein a thread pull ring is sleeved on an outer wall of an upper joint 5 of the upper joint part; a core connecting head 32 is arranged inside an inner cavity of the upper joint part; a protective sleeve and an O-shaped ring are arranged between the lower joint and a lower joint connector; the core connecting head 32 is arranged inside an inner cavity of the lower joint part; the core connecting head 32 of the lower joint part is connected with the core connecting head 32 of the upper joint part through a quick connecting braid line; an O-shaped ring is arranged between the upper joint part and the lower joint part connected through an insulating shell connector; and an insulating sleeve, a cylindrical positioning pin and an insulating protective sleeve are arranged in a gap between the upper joint and the lower joint. The maintenance-free anti-looseness insulating pup joint improves the stability and operating reliability of the instrument, reduces the failure incidence rate of the instrument, and effectively reduces the manufacturing cost of the instrument.
Description
Technical field
The present invention relates to a kind of machinery and the oil exploration equipment that the electric control technology combines, be specifically related to a kind of non-maintaining, anti-loosening insulating short section.
Technical background
Conventional insulating short section has adopted the semitight installation at insulated part, its advantage is quick and easy for installation, but the technological deficiency of its existence is also very obvious: at first when stressed, insulated part may rotate because axial force drives insulation crust, the shearing force that produces is cut off hold-down screw, insulated part is owing to have only end face stressed, can aggravate the wearing and tearing of part, need frequent demolition and maintenance, can shorten the whole service life of instrument, the single thread technology that adopts is when stressed, screw thread might influence the measurement effect and the insulation effect of instrument, and overall structure be longer because stressed and produce and looseningly to cause screw thread to move back button, complex structure has caused the rising of manufacturing cost.
Summary of the invention
It is good that technical problem to be solved by this invention provides a kind of insulation effect, improved the stability and the reliable shape property of instrument, reduced the rate of breakdown of instrument, effectively non-maintaining, the anti-loosening insulating short section of lowering apparatus manufacturing cost.
For solving above-mentioned technical problem, the technical scheme that the present invention takes:
Special character of the present invention is: comprise the top connection part, and insulated part and lower contact part, top connection partly comprises top connection, the screw thread draw ring, 32 core connectors, 32 core sockets, the sheathed screw thread draw ring of the outer wall of top connection 5, inner chamber is provided with 32 core connectors, and 32 core connectors are connected with 32 core sockets; Described insulated part comprises insulation crust, insulation protective jacket, lower contact partly comprises lower contact, 32 core connectors, 32 core sockets, lower contact be provided with protective sleeve, O type circle between lower contact is connected, the lower contact inner chamber is provided with 32 core connectors, and 32 core connectors connect by being connected pigtail lines fast with 32 core connectors of top connection part; Described top connection be provided with O type circle between lower contact is connected by insulation crust, be provided with insulation sleeve, cylinder alignment pin, insulation protective jacket in the gap between top connection and the lower contact; Described lower contact is connected by the anti-shell of irritating with the protection lower end cap, and helmet is provided with O type circle between being connected with protecting upward in top connection.
Be provided with bearing disc in the above-mentioned anti-filling shell, the arranged outside of bearing disc has back-up ring.
Above-mentioned top connection is fixed by hold-down nut and locking nut.
Above-mentioned insulation crust is arranged with rubber sleeve.
32 above-mentioned core sockets and protection are gone up between the helmet and are provided with back-up ring, are provided with back-up ring between 32 core sockets and the bearing disc.
Compared with prior art, beneficial effect of the present invention:
1, adopts key to connect and replace original screw to connect, avoid because of the axial force hold-down screw that fractures.
2, aspect insulation, adopt hermetic mode, when instrument is stressed,,, reduce the wearing and tearing of material so the power of assigning on single just reduces because contact area increases.
3, increase locking nut, prevent that screw thread is stressed and produce move back button, guarantee the stability of screw thread.
