<p>PROBLEM TO BE SOLVED: To provide a non-penetrating (closed) power cable terminal connection part of high reliability, which is easy to assemble and can surely prevent a power cable from being extracted after assembly.SOLUTION: The power cable terminal connection part includes: a terminal part of a power cable; a conductor connection terminal connected to a front end of a cable conductor; an epoxy porcelain bushing in which an insulator housing the terminal part of the power cable and an inner conductor are integrally formed; a contact piece interposed between the conductor connection terminal and the inner conductor to electrically connect both of them; a cable anchor part projecting from the conductor connection terminal symmetrically in a radial direction; a fixing member which is disposed in the epoxy porcelain bushing and has a through hole which allows the cable anchor part to be inserted thereto together with the conductor connection terminal and does not allow the conductor connection terminal and the cable anchor part to be extracted therefrom by rotation of them around an axis after the insertion; and a rotation prevention part which is disposed in the vicinity of the through hole to hold the conductor connection terminal and the cable anchor part so that they cannot be rotated.</p> |
