Abstract
The utility model relates to a maintenance-free and anti-loosening insulating pup joint. Conventional insulating pup joint has the defects that threads possibly loosened for excessive force application withdraw and influence instrument measuring effect and insulating effect, and that complicated structure results in the rise of manufacture cost. The pup joint comprises an upper joint part, an insulating part and a lower joint part, a thread pull ring is sheathed on the outer wall of the upper joint 5 of the upper joint part, and a 32-core joint is arranged in the inner cavity; a protective sleeve and an O-shaped ring are arranged between lower joints, a 32-core joint is arranged in the inner cavity of the lower joint, and the 32-core joint is connected with the 32-core joint of the upper joint part by a quick connection braided wire; an O-shaped ring is arranged between the upper joint and the lower joint which are connected by an insulating casing, and an insulating sleeve, a column locating pin and an insulating protective sleeve are arranged in the clearance between the upper joint and the lower joint. The utility model improves the stability and running reliability of instruments, reduces the failure occurrence rate of instruments and effectively reduces instrument manufacture cost.
Description
Technical field
The utility model relates to a kind of machinery and the oil exploration equipment that the electric control technology combines, and is 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.
The utility model content
It is good that technical problem to be solved in the utility model 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 utility model is taked:
Special character of the present utility model is: comprise the top connection part, 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, the beneficial effects of the utility model:
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.
