The utility model relates to the field of power system safety protection, even if the insulating rubber cap is blocked by the wiring head of the portable cable. The utility model comprises an insulating cylinder whose upper end closes the opening of the lower end. The lower end of the cylinder is connected with a bell-shaped cable to fix the insulating wall sleeve. The outer surface of the wall sleeve is provided with threads. A fastening nut screwed with threads is sleeved on the cylinder body, and an elastic damping insulating baffle is arranged on the upper end of the cylinder body. To ensure the reliability of insulation plugging, the double fixed mode of upper clamping slot and lower thread fastening is adopted for bare-end cable. The interior design consists of two parts, the material is insulating plastic. When sealing, the cable connector is inserted into the insulating rubber cap, in which the upper end slot of the rubber cap clamps the exposed part of the cable connector, and the lower end rotating thread fastener fastens the cable connector. The two parts play a dual role in fixing the cable. Reliable insulation plugging of connection head. Installation and disassembly are simple, and work efficiency is improved. It can be used repeatedly instead of insulating tape, which is economical and environmentally friendly.

便携式电缆接线头封堵绝缘胶帽
本技术涉及电力系统安全防护领域,即便携式电缆接线头封堵绝缘胶帽。
技术介绍
:在现有技术中,继电保护试验、调试等工作中,往往需要将屏(柜)后侧端子排的接线拆下,大多数情况接线头是带电的,所以为了防止误碰或短路需要进行绝缘处理,通常使用绝缘胶布将接线头包起来,由于绝缘胶布属于消耗品,每次需要包的接线头很多,这样既浪费了绝缘胶布提高了成本,同时包、拆绝缘胶布消耗大量时间造成工作效率降低,同时绝缘胶带粘性较大在解除绝缘,拆卸绝缘胶带的时候难度很大,容易损坏电缆线和发生人员误碰带电部分的危险情况。
技术实现思路
本技术的目的是针对上述不足而提供一种结构简单,使用方便、可靠、安全的便携式电缆接线头封堵绝缘胶帽。本技术的技术解决方案是:便携式电缆接线头封堵绝缘胶帽,其特征在于包括一个上端封死下端敞口的绝缘筒体,筒体下端连体有喇叭口状电缆固定绝缘壁套,壁套外表面带有螺纹,筒体上套有与螺纹拧接的紧固螺母,筒体内上端有弹性阻尼绝缘挡板。上述方案中,壁套壁厚由下至上逐渐变薄。弹性阻尼绝缘挡板形成喇叭口状。本技术的优点是:1、对裸头电缆采用上端卡槽,下端螺纹紧固的双固定模式,保证绝缘封堵的可靠性。内部设计为两部分(上端卡槽,下端螺纹紧固元件),材质均为绝缘塑料,进行封堵时,电缆接线头插入绝缘胶帽内部,其中胶帽内部上端卡槽将电缆接线头裸露部分卡住,下端旋转螺纹紧固元件将电缆接线紧固住,两部分元件起到双重固定作用,保证电缆线接线头可靠绝缘封堵。2、安装、拆卸简单,提高工作效率。安装时,只需要将电缆头插入到装置内部,向上插入,顶开上部带有弹性的阻尼绝缘挡板,裸露 ...
