FIELD: well drilling, particularly devices for supporting measuring instruments on a drill pipe, rod or wireline. ^ SUBSTANCE: device comprises electric connectors installed at ends of modules to be connected, member, which provides well direction and prevents module rotation and connecting member adapted for module connection. One module is provided with annular groove, another one has L-shaped slot. The connecting member is made as retailing ring with outside projecting ends. The retaining ring is installed in annular groove of one module and adapted to be inserted in L-shaped slot of another module. At least one projected end of retaining ring has shaped bent so that the shaped bent may pass into the groove and restrict the retaining ring from circumferential displacement during retaining ring turning in transversal part of L-shaped groove. To improve fixation ability retaining ring ends may be split apart and lie in different planes. One electric connector may be installed on bush which is restricted from axial movement by pins passing in sleeve grooves. The sleeve is fixed from axial displacement inside the module by means of screw. The bush is spring-loaded against the sleeve. The sleeve is provided with extension formed on outer sleeve surface and adapted to be inserted in groove formed in module end. ^ EFFECT: increased connection reliability, increased speed of module mounting and demounting operations and prevention of module damage. ^ 3 cl, 4 dwg |
