Problems solved by technology

The pin length of the 32-pin plug is 9mm. In this case, the actual contact length with the 32-pin socket is only 4.5-6mm. At this time, communication failure often occurs when debugging in a high-temperature environment.

Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0028] In the prior art, the way to compensate the gap is: a gasket is arranged between the heat absorber and the 32-core socket, and the gasket is produced in various specifications to meet different compensation requirements. However, this method takes a long time to operate, high cost, and complicated assembly (need to disassemble the inner frame, thermos bottle and 32-core socket multiple times to determine the size of the gap to install the gasket), and it is not conducive to the industrialization of high-temperature instruments in the later period. Interchangeability between bodies. ...

The displacement compensation connection structure in a thermos bottle includes a thermos bottle and a heat absorber arranged in the thermos bottle. One end of the thermos bottle is provided with a The connection hole of the body, the connection hole is provided with a 32-core socket connected to the heat absorbing body and a 32-core plug connected to the 32-core socket, and the displacement compensation connection structure in the thermos bottle also includes a connection block base, A plug base and a displacement compensation nut, the connection block base is provided with a through threaded hole, the plug base is installed in the connection hole and fixedly connected with the 32-pin plug, the connection block base is installed in the The thermos bottle is provided with one end of the connection hole, and the displacement compensation nut is screwed into the threaded hole and abuts against the plug base.

Description

technical field [0001] The application relates to but is not limited to the field of logging instruments, in particular to a connection structure for displacement compensation in a vacuum flask. Background technique [0002] High-temperature wireline logging instruments are very suitable for the measurement of unconventional oil wells in various high-temperature and high-pressure environments. One of the important changes in upgrading conventional wireline tools to high-temperature cable tools is to improve the temperature resistance of the circuit sub-section (control sub-section) , Here just need to use thermos bottle and absorber. Among them, the thermos bottle can isolate the heat transfer between the circuit skeleton and the shell, so that the circuit board and electronic components on the circuit skeleton in the thermos bottle are in a relatively low temperature environment; The heat emitted by electronic components during the working process (the heat absorber and th...
