Abstract

The invention relates to an underground instrument for magnetic coupling communication, which is formed by connecting a plurality of instrument short sections. The male buckle end of one of the instrument short sections is connected with the female buckle end of the other instrument short section. Magnetic coupling communication assemblies of two instrument short sections mainly comprise electric contact columns, communication coils, circuit board assemblies, shells, springs, and the like; and the communication coils which are respectively positioned on the two short sections maintain a certain distance and can realize two-way communication by utilizing electromagnetic induction. By adopting the instrument, a multi-core connecting plug is not needed when all the short sections are connected, the reliability of underground working is improved, and the scene short section replacement is rapid.
