The utility model discloses a wedge-shaped tension clamp, which includes a thread clamp body and a U bolt with a connecting thread clamp body. A wedge-shaped jacket is inserted in the online clip body, and a thread jacket is composed of two parts of symmetry. The lower part of the clamp body is provided with an opening. The special place is that the online clip body is located on both sides of the opening. Along its longitudinal symmetry, there is an integrated swallow tailed card along which the longitudinal section of the swallow tail shaped card is a wedge with a narrow front and a wide width. The wedge-shaped cover plate is inserted under the main body of the online clip, and a swallow tailed groove is set on the wedge-shaped cover plate and the swallowtail shaped card along the opening side is stuck on the edge of the opening. The beneficial effect is that the wedge shaped cover plate greatly enhances the tensile strength and the structure of the wedge-shaped cable clamp, so that the wedge-shaped tension line is clamped by the wind and snow weather when installing the fastening wire or in the electricity operation, and the safety performance is greatly improved; the line can be increased to 35~66 kilovolt voltage grade, and the voltage grade is high.

楔形耐张线夹
本技术涉及一种电力金具,特别涉及一种楔形耐张线夹。
技术介绍
现有的楔形耐张线夹包括铝合金制成的线夹主体和连接线夹主体的U型螺栓,在线夹主体内设有楔形塑料夹线套,塑料夹线套为对称的两体组合而成,用于夹紧导线。该楔形耐张线夹用在1千伏至10千伏电压等级的线路拉线用,为了将导线放入夹线套内,线夹主体下部为开口结构。这种楔形耐张线夹存在的问题是:1、在安装紧固导线时容易撑裂线夹主体;2、在导线通电运行过程中当遇风或凝霜时,导线拉力增大,容易导致楔形耐张线夹断裂造成事故,且此楔形耐张线夹仅能使用于10千伏以下线路,使用电压等级不高;3、在导线拉力增加时易使U型螺栓变形,导致导线下垂使塑料夹线套卡线产生松动,造成事故。
技术实现思路
本技术所要解决的技术问题是提供一种结构牢固,抗拉强度高,安全性能好,使用电压等级高的楔形耐张线夹。为解决上述问题,本技术采用如下技术方案:一种楔形耐张线夹,包括线夹主体和连接线夹主体的U型螺栓,在线夹主体内插装有楔形夹线套,夹线套为对称的两部分组成的分体式结构,线夹主体下部设有开口;其特殊之处是:在线夹主体上位于开口两侧沿其纵向对称设有一体的燕尾形卡沿,燕尾形卡沿的纵截面为前窄后宽的楔形,在线夹主体下面插装有楔形盖板,在楔形盖板上设有燕尾形卡槽并通过燕尾形卡槽卡在开口两侧的燕尾形卡沿上。作为进一步优选,在U型螺栓上设有支撑块,支撑块两端为套管状且分别套在U型螺栓的两个直杆上,用于避免U型螺栓变形而导致导线下垂。作为进一步优选,所述支撑块的两端之间为工字型。作为进一步优选,所述支撑块一端通过顶丝固定在U型螺栓的直杆后端。本技术的 ...
