Abstract

本实用新型公开了一种光缆悬垂线夹,它由内层预绞丝、扣在内层预绞丝中部外表面的橡胶夹具、缠绕在内层预丝及橡胶夹具外的外层预绞丝、夹在外层预绞丝缠绕的橡胶夹具处的铝夹板及与铝夹板连接的U形环组成,在橡胶夹具的内侧面沟槽的曲面上设有多个凸纹。由于本实用新型光缆悬垂线夹的橡胶夹具内侧面沟槽设置了凸纹,增大了橡胶夹具的握力和摩擦力,避免了由于橡胶夹具在外力作用时产生位移累加后对光缆的损坏。

Description

光缆悬垂线夹
本实用新型涉及一种光缆架空用配套金具,具体地说涉及一种架空光缆用的光缆悬垂线夹。
目前,在光缆的架空作业中,光缆的悬垂线夹以97年在市场上见到的桂林天地光纤通信有限公司生产的光缆预绞式悬垂线夹为例:它由内层预绞丝、扣在内层预绞丝中部外表面的橡胶夹具、缠绕在内层预丝橡胶夹具外的外层预绞丝、夹在外层预绞丝缠绕在橡胶夹具处的铝夹板及与铝夹板连接的U形环组成,其缺陷是橡胶夹具的内侧面沟槽为平滑曲面,在使用时,对内层预绞丝及光缆的握力、摩擦力不足,尤其是在北方温差较大的地方,或受风力等较大外力作用时,较易使橡胶夹具与内层预绞丝间产生位移。
本实用新型的目的是针对现有技术的不足,提供一种能增大橡胶夹具握力和摩擦力的光缆悬垂线夹。
本实用新型的目的是这样实现的,光缆悬垂线夹由内层预绞丝、扣在内层预绞丝中部外表面的橡胶夹具、缠绕在内层预丝及橡胶夹具外的外层预绞丝、夹在外层预绞丝缠绕在橡胶夹具处的铝夹板及与铝夹板连接的U形环组成,其特征在于,所述的橡胶夹具的内侧面沟槽的曲面上设有多个凸纹。
由于本实用新型光缆悬垂线夹的橡胶夹具内侧面沟槽设置了凸纹,增大了橡胶夹具的握力和摩擦力,避免了由于橡胶夹具在外力作用时产生位移累加后对光缆的损坏。
附图1为光缆悬垂线夹示意图。
附图2为橡胶夹具示意图。
下面结合附图对本实用新型作进一步详细描述,由图1可知在光缆5的表面缠绕内层预绞丝4后,在内层预绞丝4的中部外表面环扣橡胶夹具6,由图2可知,橡胶夹具6为纺锤形,由中线分为两个半块,其切面为内侧面,橡胶夹具6的内侧面沟槽内设有凸纹7。在橡胶夹具6和内层预绞丝4的外表面缠绕有外层预绞丝3,在外层预绞丝缠绕在橡胶夹具处安装有铝夹板2,与铝夹板2连接有U形环1,U形环1连在起支撑作用的杆、塔上。
