Beschreibung
Zusammenfassung:	The invention discloses an insulation short joint and a manufacturing method thereof. The insulation short joint comprises an upper connector, a lower connector, keys and an insulation mechanism. The upper connector and the lower connector both comprise boss structures. The upper connector and the lower connector are in limited connection through the boss structures. Key grooves are reserved in the connecting position of the boss structures. The keys are arranged in the key grooves. The insulation mechanism is arranged on the boss structures. Tensile force and pressure transmitted by drilling are borne by the boss structures, the keys bear torque transmitted by drilling, the insulation mechanism is used for insulation, and data transmission quality and normal drilling work are guaranteed.
