<p>PURPOSE:To prevent a gap from occurring between the tip of a grounding layer and an insulating layer on an equipment side and prevent insulating performance from lowering by forming an annular protrusion at the tip of the grounding layer. CONSTITUTION:A cable 2 is connected to a coil side via a contactor 9, so that when an insulating layer 4 on the cable side is fitted to an insulating layer 3 on the exit side the tip of a protrusion 8 can be put in contact with a grounding layer 7 on the coil side with slight push. As a result, the entry of water from the outside is prevented if a gap occurs inside the protrusion 8, and discharge between the tip of the grounding layer on the cable side and the layer 7 is prevented. In addition, even if curled winding occurs somewhat in the cable 2, the deflection of the protrusion 8 maintains contact with the layer 7 to provide long-time insulating performance against rain, wind and sunlight. By forming the protrusion 8 in multiple steps with low-compression rubber, thrust is reduced when the cable 2 is connected thereto and assembling work is simplified.</p> |
