Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in figures 1-4, logging instrument multi-core connector butt junction location structure designed by the present invention, comprise male connector main body 1 and female joint body 9, the cylindrical wall of male connector main body 1 is provided with the screw shackle 2 with its rotatable engagement, screw shackle 2 adopts split type structure, be integrated during installation, the inner circle wall of female joint body 9 be provided with the screw thread matched with screw shackle 2, thus male connector main body 1 and female joint body 9 are connected as a single entity.The cylindrical wall of male connector main body 1 is also provided with O RunddichtringO 16, the O RunddichtringO 16 matched with the inner circle wall of female joint body 9 and is provided with twice, corrode in order to stop down-hole liquid or moisture.
Detachablely in the inner chamber of above-mentioned male connector main body 1 be installed with male joint retaining ring 4, detachablely in the inner chamber of male joint retaining ring 4 be installed with male joint plug-in unit 6, the front end of male joint retaining ring 4 is provided with outwardly male joint location semi-ring 4a.Specifically, be located by connecting by the first positioning key 7 circumference between male joint retaining ring 4 and male connector main body 1, and connected by the first end face back-up ring 8 axial location.And, the rear end of male joint retaining ring 4 is provided with the male joint pressure ring 3 with its threaded engagement, male joint pressure ring 3 abuts with the convex shoulder end face of male joint plug-in unit 6 and coordinates, also be provided with the first radial peg 5 between male joint retaining ring 4 and male joint plug-in unit 6, thus realize the axial and circumferential location of male joint plug-in unit 6.
Detachablely in the inner chamber of above-mentioned female joint body 9 be installed with female joint retaining ring 10, detachablely in the inner chamber of female joint retaining ring 10 be installed with female joint plug-in unit 11, the front end of female joint retaining ring 10 is provided with outwardly female joint location semi-ring 10a.Specifically, be located by connecting by the second positioning key 15 circumference between female joint retaining ring 10 and female joint body 9, and connected by the second end face back-up ring 12 axial location.And, the rear end of female joint retaining ring 10 is provided with the female joint pressure ring 14 with its threaded engagement, female joint pressure ring 14 abuts with the convex shoulder end face of female joint plug-in unit 11 and coordinates, also be provided with the second radial peg 13 between female joint retaining ring 10 and female joint plug-in unit 11, thus realize the axial and circumferential location of female joint plug-in unit 11.
The wall thickness design that semi-ring 10a is located in wall thickness and the female joint of above-mentioned male joint location semi-ring 4a is equal, and the wall thickness of male joint location semi-ring 4a is not less than 1/4 of male joint retaining ring 4 body thickness, the wall thickness of female joint location semi-ring 10a is not less than 1/4 of female joint retaining ring 10 body thickness.Design the strength and stiffness that above-mentioned enough wall thickness can guarantee location structure, thus it is firm that two-stage structure is docked, improve packaging efficiency and the service efficiency of logger.
When above-mentioned male connector main body 1 and female joint body 9 are connected as a single entity, male joint plug-in unit 6 and female joint plug-in unit 11 are in mutual grafting mated condition, and male joint location semi-ring 4a and female joint are located semi-ring 10a and be encircled into the firm full circle ring of a Stability Analysis of Structures.
Operating principle of the present invention is as follows: the outwardly male joint location semi-ring 4a arranged respectively by the front end of male joint retaining ring 4 and female joint retaining ring 10 and female joint location semi-ring 10a realizes its circumference constraint, achieves a butt joint after male joint plug-in unit 6 and lock pin one_to_one corresponding on female joint plug-in unit 11 by rotating screw shackle 2.When male connector main body 1 is docked with female joint body 9, male joint plug-in unit 6 and female joint plug-in unit 11 have relative position requirement, can not relatively rotate when male connector main body 1 and female joint body 9 when docking, because male joint plug-in unit 6 and female joint plug-in unit 11 are separately fixed in male joint retaining ring 4 and female joint retaining ring 10, during with any circumferential position docking male connector main body 1 with female joint body 9, male joint retaining ring 4 first contacted before screw shackle 2 enters to detain with female joint retaining ring 10, circumferential position is adjusted by rotation male connector main body 1 or female joint body 9, now male joint location semi-ring 4a and female joint are located semi-ring 10a and are encircled into full circle ring and can retrain it and relatively rotate, after screw thread enters button, namely threaded together connecting ring 2 completes docking.
