CONNECTION DEVICE OF FREELY CONNECTABLE/SEPARABLE POWER CABLE

PROBLEM TO BE SOLVED: To avoid difficult connection and separation work owing to the rigidity and weight of a power cable. SOLUTION: Three junction part bodies 20, 20 and 20 per one phase are arranged in 1 line in a support part body 10 of a power cable 16. These junction part bodies 20 establish electrical connection by inserting a central conductor 20d into a hole 20c axially bored in a truncated cone projecting part 20b made of insulating material, and by inserting a continuous conductor junction part 20e into a bottomed hole bored in the central conductor 20d. The power cable 16 is electrically connected to a base end of the central conductor 20d. These components are covered with a junction part body case 20a made of insulating material. A joining part body 30 can be fitted in a straddling relation to three junction part bodies 20, 20 and 20, and electrically connects insertable and extractable connecting conductors 30a, 30a and 30a to joining conductor junction parts 20e, 20e and 20e of the junction part bodies 20, 20 and 20, and is integrally covered with a joining part body case 30c made of insulating material. In addition, three truncated cone recessed parts 30d are provided corresponding to the truncated cone projecting part 20b.
