Wire connecting device for drilling tool

Abstract

The invention relates to the technical field of wire connecting devices, in particular to a wire connecting device for a drilling tool. The wire connecting device comprises a first drill collar, a guide part and a second drill collar, wherein the inner side of the right end of the first drill collar is fixed with the outer side of the left end of the second drill collar, a guide part mounting groove is formed in the wall of the inner cavity of the right portion of the first drill collar, the guide part is fixedly mounted into the guide part mounting groove, and a vertical hole and a horizontal blind hole which are communicated are respectively formed in the upper portion and the right portion of the guide part. The wire connecting device has the advantages that the wire connecting device is reasonable and compact in structure, convenient to use, high in reliability, small in size and widely applicable to the connection of different functional modules of mechatronics drilling tools, the guide-out wire of the exploring tube of the second drill collar can be connected with the guide-out wire of the threading hole of the first drill collar by the coordination of the first drill collar, the guide part, the second drill collar, a rotary plug, a rotary socket and the exploring tube, operation is facilitated, and work efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of wire butt joint devices, and relates to a wire butt joint device for drilling tools. Background technique [0002] In the mechatronic drilling tool, when some electronic components are installed on the outer wall of the drill collar or need to be drilled into the side wall of the drill collar to insert wires, and some electronic components are installed in the probe tube in the flow channel of the drill collar, it involves The problem of power transmission and signal transmission between the side wall of the drill collar and the probe pipe. Due to the limitation of the space size of downhole tools, and considering the convenience of installation, replacement and maintenance, downhole tools with electronic systems usually adopt a modular design method, that is, the electronic system that realizes a specific function is encapsulated in a drill collar. The module is an independent system relative to the out...
