<p>PROBLEM TO BE SOLVED: To provide an improved sheath movement preventing structure of a power cable terminal part which can prevent sheath contraction movement by a simple work, without the use of special technique and special tools. SOLUTION: A spring ring 7 has a cutting part which can open on a cable sheath in a power cable terminal part. An acute angle part 12 of the inner surface of the spring ring is set so that the part 12 abuts against the cable sheath 2, which is covered with a contraction tube 11 (heat shrink tube or cold shrinkable tube). By making the acute angle part 12 of the inner surface of the spring ring 7 cut into the cable sheath 2, a blister 8 is formed in the contraction tube 11. By fastening directly the adjacent part of the blister with the fixing part of a fixing bracket 6, the cable sheath is prevented from moving towards the bracket.</p> |
