Multi-core direct-insert electric connection structure for while-drilling instrument

Abstract

The invention relates to a multi-core direct-insert electric connection structure, in particular to a multi-core direct-insert electric connection structure for a while-drilling instrument. The multi-core direct-insert electric connection structure comprises a socket shell and a plug shell, wherein the socket shell is arranged at the end part of the while-drilling instrument A and has a guiding function, and the plug shell is arranged at the end part of the while-drilling instrument B and has a guiding function; a socket inner core with a buffering function is arranged in the socket shell; anda plug inner core with a buffering function is arranged in the plug shell. The invention has the advantages that by adopting the above-mentioned technical scheme, the multi-core direct-insert electric connection structure for a while-drilling instrument can realize multi-core electric connection between underground while-drilling instruments, the number of the electric connection needle cores canbe expanded to more than 25 needles, and the mixed loading of strong electricity and weak points can be realized. In addition, the electric connection structure has simple structure, short axial dimension, good vibration resistance and reliable connection, which can realize blind insertion and is convenient to connect.

Description

technical field [0001] The invention relates to a multi-core in-line electrical connection structure, in particular to a multi-core in-line electrical connection structure for drilling instruments. Background technique [0002] At present, there are more and more types of drilling instruments, and the demand for communication and power supply between various instruments is also increasing. Therefore, the reliable electrical connection between instruments has become an urgent problem to be solved, especially the multi-core, strong and weak electric connection. It has become a difficult point, with problems such as long axial dimension, poor vibration resistance, inability to realize blind insertion, and inconvenient connection. Contents of the invention [0003] The embodiment of the present disclosure discloses a multi-core in-line electrical connection structure for a tool while drilling, so as to solve any of the above-mentioned and other potential problems in the prior ...
