Description

光纤熔接机用塑胶压锤
技术领域
本实用新型涉及一种光纤熔接机用塑胶压锤。
背景技术
光纤熔接机主要用于光通信中， 光缆的施工和维护。 主要是靠放出电弧 将两头光纤熔化， 同时运用准直原理平缓推进， 以实现光纤模场的耦合。 光 纤熔接机的压锤为安装于光纤熔接机顶盖内侧的部件， 光纤熔接时， 合上顶 盖， 压锤即与熔接机上的光纤放置 V槽配合， 用于压住光纤， 精准定位。 因 光纤直径只有几十微米， 尤其是剥了涂覆层的光纤非常脆弱， 容易被压断， 从而导致熔接失败， 需要重新制备光纤， 再进行熔接。 因此， 造成了光纤施 工时的工作效率低下。 目前， 市面上常用的压锤多为陶瓷材质的， 由一个带 有圆形安装孔的压锤座， 一个前端为扁平结构的陶瓷压锤主体， 压锤弹.簧， 以及一个压锤垫片盖子组成。 陶瓷压锤主体包括一圆柱形构件， 圆柱形构件 一端设置在压锤座的圆形安装孔内， 另一端设有压片。 目前使用的压锤存在 以下不足：
1.目前的压锤结构中， 压锤座的安装孔横截面为圆形， 工作时， 连接压 片的圆柱形构件通过设置在其顶部的弹簧的伸缩力上下移动， 从而达到使其 底部的压片压住光纤的目的。 在这样的结构中， 圆柱形构件与压锤座安装孔 的接触部位为整个圆柱外壁的面， 即二者为面面接触， 但为了使圆柱形结构 能够顺利地上下移动， 两个接触的面并不是完全紧贴的， 中间留有足够缝隙 以便圆柱形结构上下移动。 正因为留有的足够缝隙， 使得工作中圆柱形构件 容易出现晃动， 导致处于推进对芯过程中的光纤出现跳动， 造成光纤的熔接 损耗大，甚至会导致光纤熔结失败。
2. 目前的压锤主体前端与熔接光纤放置 V槽接触的部分是一个平面加凸 起压片设计，上述平面与熔接机机芯架 V槽接触时没有任何固定或调整部件， 致使该平面在水平范围内的可移动范围大， 容易造成压锤上的压片接触光纤 时压片不垂直于光纤放置 V槽， 从而导致光纤被压片带动， 偏离光纤放置的 V槽， 造成光纤对芯时由于角度大而出现的熔接失败问题。
3. 目前压锤多采用陶瓷材质， 陶瓷的自重及硬度都比较大， 很容易在压 光纤的过程中造成光纤的断裂。
实用新型内容
本实用新型的目的是为了解决上述存在的问题， 提供一种光纤熔接机用 塑胶压锤， 包括带有安装孔的压锤座， 压锤弹簧， 压缍主体， 以及压锤盖子， 所述压锤主体上部设于所述压锤座的安装孔内， 所述压锤盖子设于所述压锤 座上部并与之固定连接， 所述压锤弹簧设于所述压锤主体和所述压锤盖子之 间， 所述压锤主体底部还设有压片， 所述压锤主体为线接触式设于所述压缍 座的安装孔内；所述压锤主体底部压片的后端设有与光纤熔接机机芯架上的 V 槽适配的固定机构。 它既改善了压锤主体晃动间隙大的缺点， 避免了因此导 致的光纤跳动情况， 又实现了压锤主体的准确定位， 提高了压锤位置的可调 整性， 同时降低了光纤断裂的几率， 提高了工作效率。

较佳地， 所述压锤主体采用轻质材料。 较佳地， 所述压锤主体为塑胶材质。
与现有技术相比， 本实用新型的有益效果如下：
1. 本实用新型的压綞座安装孔采用六边形设计， 使得压锤主体与压锤座 安装孔是圆形柱与六边形孔相配合， 将原来的面面接触改为线接触， 使配合 更加紧凑， 减少了压锤主体的晃动间隙， 从而改善了压锤主体晃动间隙大的 缺点， 能够避免设在压锤主体的压住光纤的压片因压锤主体晃动导致的光纤 跳动情况。
2. 本实用新型把压锤主体底部单纯的压片结构改成了 V型凸起 +压片的 结构， V型突起可以和熔接机光纤放置 V槽相吻合， 方便地实现 7 "压锤的准 确定位， 可保证压锤主体上的压片垂直于光纤放置 V槽， 即可保证压片始终 垂直于光纤; 提高了压锤位置的可调整性， 即使压锤的安装位置不那么精准， 由于两个 V槽相啮合的设计， 也能把压锤定位到其工作时的正确位置。
3. 本实用新型的压锤主体采用轻质材料， 例如塑胶材质， 塑胶压锤的硬 度及自重都比陶瓷压锤要小得多， 能够在压住光纤的同时保证不压断光纤， 降低了光纤断裂的几率， 提高了工作效率。
