FIELD: physics, measurement. ^ SUBSTANCE: invention is related to the field of geophysical research and may be used in telemetering systems for fastening of electronic module, and makes it possible to increase service life of lower switcher and centraliser, and also to increase validity of measurement results by modification of centraliser design and protective jacket plug. Protective jacket plug of electronic module is arranged in the form of sleeve with cylindrical and tapered surface. Internal cavity of plug is profiled for support of electronic module chassis. On sleeve cylindrical portion thread is provided for connection to protective jacket, and sealing rings are installed. Mounting ribs are provided on tapered surface of sleeve, and on sleeve bottom, from external side, axial rod is arranged, on which centraliser is installed, arranged in the form of two coaxial cylinders with radial links in between. At that the following components are installed serially long axis on plug rod: the first shock absorber, centraliser on insulating bushing, the second shock absorber, sealing ring and nut. After nut, additional sealing rings and check-nut are installed on rod. Plug rod may have through axial channel and through radial opening. ^ EFFECT: increase of lower switcher and centraliser service life, and also higher validity of measurement results. ^ 3 cl, 2 dwg |
