具体实施方式
以下结合附图， 进一步介绍本实用新型。
请参阅图 1-7, 本实用新型的光纤接续组件， 包括光纤预埋座 1、 滑块 2和压纤块 3 , 滑 块 2可沿着光纤预埋座 1滑动， 压纤块 3设置在滑块 2与光纤预埋座 1之间， 滑块 2可沿着 压纤块 3滑动， 使压纤块 3的一端可释放地与光纤预埋座 1抵接。
进一步地， 光纤预埋座 1上设有容置槽 12 , 压纤块 3设置在容置槽 12中。 滑块 2上设 有可容置压纤块 3的空腔， 空腔的侧壁设有第一导向体 21 , 压纤块的侧面设有第一滑槽 31 , 第一滑槽 31中部设有坡度 311 ,滑块 2可通过第一导向体 21沿着压纤块的第一滑槽 31滑动， 使压纤块 3的一端可释放地与光纤预埋座的容置槽 12抵接。 请参阅图 3、 4、 8和 9, 当滑块 2的导向体 21位于压纤块的 b端时， 压纤块 3的底面与水平面的夹角约为 2° , 当滑块 2的 导向体 21沿着压纤块从 b端向 a端滑动时， 导向体 21沿着坡度 311的下坡面运动， 并抵压 下坡面， 使压纤块 3的底面与水平面的夹角逐渐变小， 当导向体 21运动至光纤接续点 121的 上方时， 压纤块 3的底面与水平面的夹角为 0, 此时， 压纤块完全压紧光纤接续点， 达到光 纤接续的目的， 如图 9所示； 当滑块的导向体 21沿着压纤块从 a端向 b端滑动时， 导向体 21沿着坡度 311的上坡面运动，并抵压上坡面，使压纤块 3的底面与水平面的夹角逐渐变大， 当导向体 21运动至 b端时， 压纤块 3的底面与水平面的夹角约为 2° , 此时， 压纤块不再压 紧光纤预埋座上的光纤接续点， 而产生了一个小空间， 方便接续光纤的插入或拔出， 如图 8 所示。 即， 滑块处于 b端点时， 压纤块与光纤预埋座的光纤放置位置留有一定空间， 方便操 作者插入待接续光纤。
