Patent ID: 11081837

Abstract:
The present invention relates to multi-core plug-in electrical connection structures, in particular to a multi-core plug-in electrical connection structure for logging while drilling tools, which comprises a socket shell with a guiding function arranged at an end of a logging while drilling tool A and a plug shell with a guiding function arranged at an end of a logging while drilling tool B; wherein the socket shell is provided with a socket inner core with a buffering effect therein; and the plug shell is provided with a plug inner core with a buffering effect therein. The present invention has the following beneficial effects: with the above technical scheme, multi-core electrical connection between downhole logging while drilling tools can be achieved, the electrical connection pins can be increased to 25 pins or more, mixed heavy current and light current connections can be realized, and the electrical connection structure is simple with short axial dimension, good anti-vibration performance, and reliable connection. The blind insertion and the convenient connection can be realized.
