<p>PURPOSE: To improve the structure at an auxiliary sleeve part such that a premolded insulation reinforcement can be mounted/demounted relatively easily on/from a conductor joint. CONSTITUTION: A contactor 21 is fixed, while being carried on an oscillation shaft 23 at a bearing part 20A, to the side face of an auxiliary sleeve 20 surrounding a connection sleeve 4. The contactor 21 is oscillated in the direction of an arrow 31 by the force of a spring 22 and engaged with an embedded electrode 7. On the other hand, a wedge member 25 screwed into the bearing part 20A is turned in the direction of an arrow 32 by means of an operating pawl 26A to advance in the direction of an arrow 33 thus pushing up the contactor 21 at the other end 21B thereof. Consequently, the contactor 21 is vibrated in the direction opposite to the arrow 31 and disengaged from the embedded electrode 7.</p> |
