Abstract
The utility model relates to a high-hydraulic-pressure-resistant sealed-type dual-core signal communication joint. In current coal mine underground structures for measuring deviation while drilling and for logging, sealing of signal lead-out communication terminals are subjected to water leakage, signal lead-out failure, signal interruption, etc., which directly affects the drilling progress of boring. The high-hydraulic-pressure-resistant sealed-type dual-core signal communication joint of the utility model comprises an outer conductive electrode and an inner conductive electrode, which have an injection-molded integral structure. An intermediate layer is arranged between the outer conductive electrode and the inner conductive electrode. The high-hydraulic-pressure-resistant sealed-type dual-core signal communication joint is resistant to the hydraulic pressure of 12MPa, is not likely to cause the phenomenon of signal output failure which may occur due to water leakage, allows related signals to be stably outputted, makes stable the two-electrode electric conduction and the signal output, and achieves excellent waterproof performance, convenient installation and reliable performance.
Description
Technical field
The utility model belongs to the colliery technical field, relates to a kind of high water pressure resistant sealed type twin-core signal and communication joint.
Background technology
At present in colliery downhole drill deviational survey and the well logging structure, the sealing that signal is drawn communication terminal all exists leaks and the phenomenons such as signal can not draw, break signal, and this kind phenomenon directly has influence on the progress of creeping into of boring.
The utility model content
Thereby the technical problem that the utility model solves provides a kind of the solution to be existed in the prior art because the problem that sealing is incessantly leaked and caused signal to export, and water resistance is superior, the high water pressure resistant sealed type twin-core signal and communication joint of two utmost point conductions and stable output signal, dependable performance easy for installation.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
A kind of high water pressure resistant sealed type twin-core signal and communication joint, its special character is: comprise outer conductive electrode, internal layer conductive electrode, outer conductive electrode, internal layer conduct electricity the integral structure that very injection moulding forms, and between outer conductive electrode, the internal layer conductive electrode intermediate layer are set.
Above-mentioned outer conductive electrode and the surface of internal layer conductive electrode are provided with axially and radially groove and hatching knurling.
Above-mentioned outer conductive electrode and internal layer conductive electrode right-hand member coat and are provided with watertight composition.
Compared with prior art, the hydraulic pressure that the utility model can anti-12MPa can not exist owing to leaking to cause signal can't export phenomenon, can be stable coherent signal is exported; Water resistance is superior, two utmost point conductions and stable output signal, dependable performance easy for installation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises outer conductive electrode 1, internal layer conductive electrode 2, outer conductive electrode 1, internal layer conductive electrode 2 are integral the formula structure by the injection moulding process pressure injection, between outer conductive electrode 1, the internal layer conductive electrode 2 intermediate layer 3 is set, intermediate layer 3 adopts nylon 66 as packing material, plays insulation and sealing function
Above-mentioned outer conductive electrode 1 and the surface of internal layer conductive electrode 2 are provided with axially and radially groove and hatching knurling, prevent moving axially and radial rotating between part after the injection moulding.
Above-mentioned outer conductive electrode 1 and internal layer conductive electrode 2 right-hand members coat and are provided with watertight composition.
The material of outer conductive electrode 1 is C17200, and there is x wire cutting straight trough the inside of outer conductive electrode 1, the radial rotating in anti-here part and intermediate layer 3, and radially car is prevented axially movable stepped hole; The material of internal layer conductive electrode 2 is C17200, internal layer conductive electrode 2 external shafts are to the straight trough mouth that is milled with three anti-radial rotatings, radially car has anti-axially movable stepped hole, and there is hatching knurling on the surface, further strengthened preventing after the injection moulding between part relatively rotating and mobile; Intermediate layer 3 when mold injection according to outer conductive electrode 1 and internal layer conductive electrode 2 inside and outside shapes and between gap nature moulding, material is nylon 66(white), function is outer conductive electrode 1 and 2 two parts of internal layer conductive electrode to be insulated form the two poles of the earth and sealing, and anti-sealing permeates from the injection moulding gap.Consider that the shrinkage of nylon 66 when cooling is greater than the shrinkage of C17200 material, therefore at the outside watertight composition that coats of structure right-hand member, watertight composition adopts the scheme of nylon parcel C17200, with the possibility of stopping to leak from the injection-moulded plastic part gap, further improves the sealing property of this structure.
This structure-forming process: first with the outer conductive electrode 1 among Fig. 1, the 2 machining moulding of internal layer conductive electrode, then be fixed in and carry out pressure injection, cooling, moulding in the injection mould.
After this shaping structures, be connected and fixed with deviational survey or well logging inserting tube first, play the 12MPa hydraulic test, do not guaranteeing to press in (namely without leaking) situation, this communication connector integral body is linked and packed with inserting tube, and the inserting tube overall structure that then will seal is packed into and is drilled with carrying out the down-hole in the drilling rod of straight trough mouth.
