description 一种胴体部3的前端部2 1设在支撑金属件6与芯件2之间，支撑金属件6的内周面12a与胴体部3的前端部12的外周面12a之间设有密封剂22的聚合物绝缘子1的密封结构，从外套5的胴体部3突出地设有小凸缘31，小凸缘31的高度低于支撑金属件6的开口端部31，小凸缘31的侧面通过密封剂22紧密粘接在支撑金属件6的开口端部13上，而且，从小凸缘31的侧面与支撑金属件6的开口端部31之间没有密封剂22挤出。 A seal construction of a polymer insulator has a core member, an outer cover member including a sheath portion and sheds, which is arranged on an outer surface of the core member, and a securing metal fitting is arranged on each end of the core member. A tip portion of the sheath portion is arranged between the securing metal-fitting and the core member, and a sealant is arranged between an inner surface of the securing metal fitting and an outer surface of the tip portion of the sheath portion. The seal construction mentioned above includes a small rib projecting radially outward from the sheath portion of the outer cover member. The small rib has a side surface connected to an open end portion of the securing metal fitting via the sealant, and the sealant does not protrude from a portion between the side surface of the small rib and the open end portion of the securing metal fitting.
