摘要：NOVELTY - The joint has an inner circular bead face (1) provided with a signal transmission passage (8). Another signal transmission passage is assembled on an outer circular bead face. A joint pipe transmission passage (9) is connected with the former signal transmission passage. Another joint pipe transmission passage is connected with the latter signal transmission passage. The signal transmission passages are mounted on the inner and outer circular bead faces to form an integral passage such that the joint pipe transmission passages are connected together via the integral passage. USE - High performance tool joint for delivering electricity and relative signal. ADVANTAGE - The joint is simple in structure, and realizes actual production. The intellectualization degree of a working condition of the joint is improved. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a high performance tool joint. Inner circular bead face (1) Inner thread pieces (2) Cylindrical hole (3) Signal transmission passage (8) Joint pipe transmission passage (9)
