Description

一种用于光纤连接器的光纤定位部件 技术领域
本发明涉及光纤连接器，更具体地说，涉及一种用于光纤连接器的光纤定位部件。
背景技术
在光纤连接器领域经常会用到如图1所示的带有V槽11的基板1作为光纤定位部件，光纤2排列在V槽11中，从而实现光纤的定位。V槽是光纤连接器中较为常用的定位结构。例如，在一些非可拆卸光纤 连接领域，经常会用到带有V槽的光纤定位件，如一项中国专利申请CN200480009831.X以及一项中国专利ZL92104890.4中都有涉及到带有V槽光纤固定件，一般包括一个带有V槽的基板，和一个与基板适配 的盖板，光纤由V槽的两端放入V槽中，并在V槽中实现对接，然后用盖板将光纤压入到V槽中实现光纤的固定。由于光纤的直径比较细，例如常用的玻璃光纤的直径为0.125mm，所以用于光纤定位的V槽的 几何尺寸也非常小，在光纤连接器中，为了保证光纤能够实现良好对接，对机械加工的精度要求非常高，这导致V槽的加工非常困难，需要采用超高精度机械加工工艺制作，此外V槽中的尺寸不是装配直心，其尺寸需要有e2、d2和θ三个几何参数确定，装配尺寸还需要经过复杂的换算得到，无法直接测量，这会导致装配尺寸精度不稳定。
发明内容
本发明要解决的技术问题在于，针对现有技术的光纤连接器中的带有V槽的光纤定位部件的上述缺陷，提供一种带有方槽的光纤定位部件。
本发明解决其技术问题所采用的技术方案是：构造一种用于光纤连接器的光纤定位部件，包括基板，所述基板上设置有至少一条光纤定位槽，所述光纤定位槽的横向截面为矩形。
在本发明所述的光纤定位部件中，所述基板上设置有多条所述光纤定位槽，多条所述光纤定位槽等间距平行设置。
在本发明所述的光纤定位部件中，所述光纤定位槽的横向截面的宽度略大于光纤的直径。
在本发明所述的光纤定位部件中，所述光纤定位槽的横向截面的高度略小于光纤的直径。
在本发明所述的光纤定位部件中，所述光纤定位槽的横向截面的高度略大于光纤的直径。
在本发明所述的光纤定位部件中，所述光纤定位槽的横向截面的高度等于光纤的直径。
在本发明所述的光纤定位部件中，所述光纤定位槽的端面具有用于导向的倒角结构。
在本发明所述的光纤定位部件中，所述光纤定位部件还包括盖在所述基板上的盖板。
在本发明所述的光纤定位部件中，所述基板为塑料板、石英板或金属板。
实施本发明的光纤定位部件，具有以下有益效果：本发明的用于光纤连接器的光纤定位部件采用矩形截面的光纤定位槽，具有便于加工，易于测量等优点，可以广泛应用于各种光纤连接器。
附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图1是现有的光纤定位部件的示意图；
图2是本发明的光纤定位部件的结构示意图；
图3是本发明的光纤定位部件带有盖板的示意图；
图4是现有的光纤定位部件与盖板配合的示意图。
具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图2所示为本发明的用于光纤连接器的定位部件的一个实施例，包括基板1，该基板1可以由塑料、金属或石英制成，在基板1上加工有三条光纤定位槽12，三条光纤定位槽12等间距平行设置，光纤定位 槽12的横向截面为矩形（包括方形）。
光纤定位槽12的宽度d1一般选择略大于光纤的直径，而光纤定位槽12的高度e1则根据其所在光纤连接器中的作用来选择。
在需要光纤定位部件对光纤有一定的固定作用时，光纤定位槽12横向截面的高度e1等于或略微小于光纤2的直径，优选高度e1略小于光纤2的直径，例如对于常用的玻璃光纤，e1等于或略微小于0.125mm。参看图3，为盖上盖板3时，光纤2可以在光纤定位槽12中自由活动，光纤2放置到预定位置时，盖上盖板3后，并将盖板3压紧在基板1上，依靠盖板3对光纤2压紧固定，这种结构可以用在现场组装的光纤连接中。
在光纤定位部件仅仅在光纤连接器中起导向定位作用时，光纤定位槽12的横向截面的高度e1需要略微大于光纤的直径，保证光纤2可以沿光纤定位槽12的纵向方向在光纤定位槽12中自由滑动，这种结构多用在裸光纤直接对中连接的光纤连接器中。
光纤定位槽12的横向截面的高度e1一般大于或等于光纤2的直径。
与V槽结构相比，V槽需要高度e2、夹角θ和宽度d2三个几何参数才能确定其截面的几何形状，而且几何尺寸非常小，给测量和加工都带来很大的困难。另外，最重要的装配尺寸还只有通过换算得到，不能直接测量。V槽有一尖端，这对于模具来说必须有一尖端部位，模具容易磨损，造成加工精度难以保证；对于截面为矩形的光纤定位槽12来讲，只需要宽度d1和高度e1即可确定其截面形状，较V槽少一 个几何参数，这会给加工和测量带来很大的便利。
图3示出了光纤定位部件的基板和盖板3配合的示意图，盖板3盖在基板1上，将光纤2限制在光纤定位槽12中。
为了方便光纤2进入到光纤固定槽12中，通常在光纤定位槽12的端面设置有导向的倒角结构，对光纤2起到导向的作用。参看图3和图4,在保证相邻光纤中心距A相等的情况下，采用矩形截面的光纤定位槽12结构的相邻两光纤定位槽的间距B1大于相邻两V槽之间的距离B2，这会导致光纤定位槽12端面倒角的尺寸大于V槽端面的倒角尺寸，使得矩形截面的光纤定位槽12在其端面的倒角更易加工而且具有更好的导向作用。由于光纤对于弯曲半径有限制，所以采用多芯光纤时，光纤分开的间距不能过大，导致相邻光纤定位槽的间距不能过大，这对V槽结构来讲也是一种限制，而对于矩形截面的光纤定位槽来讲，限制会小一些。
本发明的用于光纤连接器的光纤定位部件采用矩形截面的光纤定位槽，具有便于加工，易于测量等优点，可以广泛应用于各种光纤连接器。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护之内。
