Abstract

本发明公开一种面接触的穿刺线夹，包括上夹体、下夹体，其特征在于：所述上夹体与下夹体通过螺栓连接；所述上夹体、下夹体相对应处设置凹槽；所述上夹体设置压紧螺栓，所述压紧螺栓与上夹体螺纹连接；所述压紧螺栓下端与穿刺座抵接；所述锥头数量为3个，分别为两边的边锥头和中间位置的正锥头；所述边锥头的高度高于正锥头；所述边锥头与穿刺座倾斜设置。本发明的原理及优点是：由于边锥头的高度比正锥头高，所以，两侧的边锥头首先刺破绝缘层，随着压紧螺栓的旋紧，由于边锥头是倾斜设置的，因此其必然向两侧倾斜，这样，边锥头与电线的接触就变成面接触，压紧螺栓进一步旋紧后，正锥头与电线点接触，而两个边锥头则进一步扩大了接触面积。

Description

一种面接触的穿刺线夹
技术领域
本发明涉及电力设备领域，具体说是一种金具，更具体说是一种穿刺线夹。
背景技术
穿刺线夹广泛应用于电力设备中，现有的穿刺线夹一般都是采用螺栓的压力，将锥头刺破绝缘层后与电线接触；在锥头刺入后，锥头与电线的接触一般为点接触，其弊端是由于接触面积过小，再加上金属的氧化等，在接触点易发生接触不良的后果，带来电力设备的损坏。中国专利申请号201220026879.3公开了一种限位型穿刺线夹，“它包括由锁紧螺栓紧固的上线夹和下线夹座的线夹部分，上线夹的螺孔与穿刺螺栓配合，环绕穿刺螺栓的穿刺锥头设有环形限位台。”该专利解决了锥头刺入深度的控制问题，但没有解决“点接触”问题。
发明内容
为解决上述技术问题，本发明的目的是提供一种面接触的穿刺线夹，具体技术方案如下：
一种面接触的穿刺线夹，包括上夹体、下夹体，所述上夹体与下夹体通过螺栓连接；所述上夹体、下夹体相对应处设置凹槽；所述上夹体设置压紧螺栓，所述压紧螺栓与上夹体螺纹连接；所述压紧螺栓下端与穿刺座抵接；所述穿刺座上设置多个锥头。
所述锥头数量为3个，分别为两边的边锥头和中间位置的正锥头；所述边锥头的高度高于正锥头；所述边锥头与穿刺座倾斜设置。
本发明的原理及优点是：由于边锥头的高度比正锥头高，所以，两侧的边锥头首先刺破绝缘层，随着压紧螺栓的旋紧，由于边锥头是倾斜设置的，因此其必然向两侧倾斜，这样，边锥头与电线的接触就变成面接触，压紧螺栓进一步旋紧后，正锥头与电线点接触，而两个边锥头则进一步扩大了接触面积。
附图说明
图1为本发明的结构示意图；
图2为穿刺座与锥头结构示意图。
具体实施方式
下面结合附图具体说明本发明，如图1、图2所示，本发明包括上夹体1、下夹体2，所述上夹体1与下夹体2通过螺栓3连接；所述上夹体1、下夹体2相对应处设置凹槽6；所述上夹体1设置压紧螺栓4，所述压紧螺栓4与上夹体1螺纹连接；所述压紧螺栓4下端与穿刺座5抵接；所述穿刺座5上设置多个锥头。
本实施例的锥头数量为3个，分别为两边的边锥头52和中间位置的正锥头51；所述边锥头52的高度h2高于正锥头的高度h1；所述边锥头52与穿刺座5倾斜设置，即图2中锥头的锥心线与穿刺座的夹角a小于90度。
锥头材料可采用延展性能较好的金属，以防止锥头根部断裂，还可将锥头根部形状设置成圆弧过渡，以防止应力集中。
锥头数量可根据设计要求进行改变。
