Docking assembly between rotating and static signal cables in borehole inclinometer

The invention discloses a docking assembly between rotating and static signal cables in a borehole inclinometer, which relates to a docking assembly. The invention has the structure that a circular insulating plate is provided with a fixing hole, concentric copper rings and a roller rotating shaft in sequence from outside to inside; a second socket is respectively connected with a plurality of copper rings through a plurality of core wires in the signal cable; one end of each resilient contact on the contact base is respectively connected with a plurality of copper rings in a close contact way; and the other end of each resilient contact, the signal cable, a second plug and a manual reading instrument are connected with each other end to end in sequence. The invention can complete the butt joint between the rotating signal cable and the fixed signal cable, thereby realizing the goal of automatic elevation measurement of a probe. The invention is not only suitable for automatic measurement of a borehole inclin
