光纤适配器，是一种光纤活动连接器，是实现光纤之间可活动连接的光无源器件，它具有光纤与光纤、光纤与有源器件、光纤与其它无源器件以及光纤与仪表之间活动连接的功能。
相关的光纤适配器包括壳体，套筒保持件和陶瓷套筒，其中，套筒保持件设置在壳体内，陶瓷套筒设置在套筒保持件内，陶瓷套筒开设有用于容纳光纤的通孔。光纤包括第一光纤和第二光纤，第一光纤和第二光纤插入陶瓷套筒两端对应地通孔内进行对接，陶瓷套筒通过自身的自由浮动提供调整空间，使第一光纤和第二光纤能够同轴对接，进而保证第一光纤的光束与第二光纤的光束平行，使光纤适配器具有良好的准直性能，需要说明的是，准直是指保持第一光纤的光束与第二光纤的光束之间相互平行。
相关的套筒保持件分为第一套筒保持件和第二套筒保持件，陶瓷套筒的一端置于第一套筒保持件的通孔内，陶瓷套筒的另一端置于第二套筒保持件的通孔内，第一套筒保持件和第二套筒保持件进行同轴对准装配，实现通孔的同轴对接。由于装配工艺存在误差，导致套筒保持件在进行实际对准装配时并未完全同轴，使得陶瓷套筒在套筒保持件的通孔内不能自由浮动，从而影响光纤适配器的准直性能。

需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
本申请实施例提供的一种光纤适配器，主要用于实现光通信系统中设备之间、设备与仪表之间、设备与光纤(或光缆)之间以及光纤(或光缆)与光纤(或光缆)之间可活动连接的光无源器件。
以光纤适配器应用到连接器为例，需要说明的是，本申请的应用场景类型并不对本申请产生限定。结合图1对光纤适配器的工作原理进行示例性说明。光纤适配器可以包括套筒保持件1、壳体2和陶瓷套筒3。壳体2可以是大致四方体结构，其中一端为开口端，壳体2围合形成空腔21，与开口端相对的另一端的端面设置有通孔，通孔的面积远小于该端面的面积。套筒保持件1从通孔插入壳体2的空腔内，沿套筒保持件1的长度延伸方向，套筒保持件1的一端位于空腔内，相对的另一端凸出于壳体2的外表面。套筒保持件1可以是大致圆柱体形结构，套筒保持件1具有贯通的第一腔体11，套筒保持件1的一端设置有第一入口121，相对的另一端设置 有第二入口122，第一入口121和第二入口122均与第一腔体11连通，第一腔体11用于放置陶瓷套筒3。陶瓷套筒3具有第二腔体31，陶瓷套筒3的一端设置有第三入口321，相对的另一端设置有第四入口322，第三入口321和第四入口322均与第二腔体31连通，第二腔体31用于放置陶瓷插芯。标准连接器从壳体2的开口端插入空腔21，并与套筒保持件1靠近第一入口121的一端连接，标准连接器的陶瓷插针插入第一入口121，陶瓷插针内的光纤纤芯插入陶瓷插芯。小型连接器从壳体2开口端相对的另一端接入，并与套筒保持件1靠近第二入口122的一端连接，小型连接器的陶瓷插针插入第二入口122，陶瓷插针内的光纤纤芯插入陶瓷插芯，并与标准连接器的光纤纤芯连接。光纤适配器通过套筒保持件1、壳体2和陶瓷套筒3等组件连接标准连接器与小型连接器之间光纤纤芯，实现光路的对接与传输。
在本申请实施例中，如图2和图3所示，光纤适配器包括壳体2、陶瓷套筒3、保持件4和保持盖板5，壳体2具有空腔22，空腔包括连通的第一空腔221和第二空腔222，第一空腔221和第二空腔222分别对应连通壳体2的相对两端。具体的，壳体2可以是大致四方体薄壁结构，如图4所示，壳体2的一端为用于插入保持件4的开口端，开口端相对的另一个端面与壳体2的四个侧面围合形成第二空腔222，用于容纳标准连接器的接口端。如图3所示，第一空腔221与第二空腔222连通，第一空腔221用于放置保持件4。可选的，如图5a所示，第一空腔221可设置在壳体2的端面与壳体2的下侧面连接处；如图5b所示，第一空腔221也可以设置在壳体2的端面与壳体2的左(右)侧面连接处；如图5c所示，第一空腔221还可以设置在壳体2的端面与壳体2的上侧面连接处。优选地，在本申请实施例中，第一空腔221采用如图5a所示的结构进行后续阐述。由第一空腔221至第二空腔222，腔体体积增大，共同形成空腔22。
如图6和图7所示，光纤适配器还包括保持件4，与壳体2一体成型，设置于第一空腔221内；其中，保持件4围成容纳腔41，容纳腔41具有位于一端的第一开口421、位于另一端的第二开口422和沿保持件4的长度方向延伸的第三开口43。具体的，保持件4与壳体2是一体成型的结构，该结构可以避免装配式结构需要焊接或者粘接的问题，还可以避免装配过程 中因保持件4偏斜而导致的不同轴问题。保持件4可沿第一空腔221插入第二空腔222，保持件4的一端可以与插入到第二空腔222的标准连接器端子连接，保持件4的另一端与壳体2外的小型连接器端子连接。保持件4的设置形式灵活多样，保持件4可以全部位于空腔22内，保持件4也可以部分设置在第二空腔222内，另一部分突出壳体2。需要说明的是，保持件4与壳体2的相对位置关系并不对本申请产生限定。在示例性的实施例中，可以采用如图6所示的设置方式，即保持件4一部分位于壳体2内，另一部分位于壳体2外。如图7所示，保持件4可以是大致圆柱形的筒体结构，筒体具有一个侧面和两个相对的端面，由筒体侧面和两个端面围合形成的空间即所述的容纳腔41。沿筒体的长度延伸方向，在筒体侧面开设有第三开口43，作为放置陶瓷套筒3的入口，沿筒体的周向，第三开口43可以开设于筒体侧面的任意位置。筒体的两个端面分别对应开设第一开口421和第二开口422，使得位于保持件4两端的连接器的陶瓷插针能够伸入到容纳腔41。保持件4为一体式结构，陶瓷套筒3可以通过第三开口43，沿保持件4的径向方向插入，并放置于保持件4的容纳腔41内，筒体的中心轴线即为保持件4的轴线，并且该轴线仅有一条，陶瓷套筒3可以与保持件4共轴线，陶瓷套筒3可以在保持件4内自由浮动。如图8所示，相关的套筒保持件结构包括第一套筒保持件131和第二套筒保持件132，第一套筒保持件131具有第一容纳腔1311，第二套筒保持件132具有第二容纳腔1321，陶瓷套筒3的一端插入第一容纳腔1311，陶瓷套筒3相对的另一端插入第二容纳腔1321，第一容纳腔1311和第二容纳腔1321共同形成放置陶瓷套筒3的空间，第一套筒保持件131和第二套筒保持件132通过同轴对准装配连接形成套筒保持件，由于实际装配过程存在一定的误差，第一套筒保持件131的轴线与第二套筒保持件132的轴线不在同一条直线上，第一容纳腔1311和第二容纳腔1321所形成的腔体有一定的偏斜，陶瓷套筒不能够在容纳腔内自由浮动，第一光纤和第二光纤在插入陶瓷套筒3两端对应地通孔内进行对接时，第一光纤和第二光纤不能够同轴对接，进而影响光纤适配器的准直性能。本申请实施例的保持件4，一方面，提供了能够放置陶瓷套筒的空间，另一方面，保持件4为一体式结构，并与壳体2一体成 型，其轴线为结构自身的轴线，避免了多个套筒保持件因装配误差导致套筒保持件之间彼此不共轴线的问题，从而保持了陶瓷套筒的可浮动性，提升了光纤适配器的准直性能。
如图9所示，光纤适配器还包括保持盖板5，用于可拆卸的与保持件4连接以封闭第三开口43。具体的，陶瓷套筒从第三开口43放入到保持件4的容纳腔，陶瓷套筒靠近第三开口43的一侧处于暴露状态，保持盖板5可大致覆盖保持件4的第三开口43，为陶瓷套筒暴露的部分提供遮挡与保护。保持盖板5与保持件4连接，避免陶瓷套筒从保持件4的第三开口43掉落。保持盖板5的结构尺寸与第三开口43尺寸相适配，可以保证彼此之间良好的贴合性，保持盖板5与保持件4之间非固定连接，便于陶瓷套筒的放入和取出。
如图10所示，光纤适配器还包括陶瓷套筒3，设置在容纳腔41内并与保持盖板5相邻,陶瓷套筒3具有连通第一开口421和第二开口422的第三空腔33，陶瓷套筒3被限制在所述容纳腔41内。需要说明的是，限制在容纳腔41内，是指在容纳腔41内可以有一定范围的浮动，因为陶瓷套筒3和保持件4之间有间隙，但是陶瓷套筒3不能移动超出容纳腔41。保持件4两端连接的连接器的陶瓷插针，对应地插入到第一开口421和第二开口422内，并将陶瓷插针内的光纤纤芯插入到第三空腔33的陶瓷插芯中。
本申请实施例的保持件4与壳体2一体成型，并在保持件4的长度延伸方向开设第三开口43，陶瓷套筒3可以通过第三开口43放置于保持件4围成的容纳腔41内，保持盖板5可以封闭第三开口43，并与保持件4可拆卸的连接。保持件4是一体式结构，不需要进行同轴对准装配，消除了多个保持件不同轴而带来的准直性能缺陷。
在一些实施例中，如图11所示，第三开口43包括长边431和短边432，长边431包括第一长边4311和第二长边4312均与保持件4的长度延伸方向平行；短边432与长边431垂直，短边432包括连接第一长边4311一端和第二长边4312一端的第一短边4321，以及连接第一长边4311另一端和第二长边4312另一端的第二短边4322。具体的，陶瓷套筒3可以是大致的圆柱体型结构，沿陶瓷套筒3的长度延伸方向，陶瓷套筒3的一端至相对 的另一端，直径均大致相同，第三开口43的第一长边4311和第二长边4312均平行于保持件4的轴线，即第一长边4311和第二长边4312之间间隔的距离相等，便于陶瓷套筒3从第三开口43放入保持件4的容纳腔41。
在一些实施例中，如图12所示，第一长边4311和第二长边4312的长度L1均大于陶瓷套筒3的长度L2。具体的，第一长边4311和第二长边4312的长度相等，均为L1，L1大于陶瓷套筒3的长度L2，陶瓷套筒3才能够通过保持件4的第三开口43的长度方向，放入到容纳腔。
在一些实施例中，如图12所示，第一长边4311和第二长边4312之间的距离L3大于陶瓷套筒3的外径L4。具体的，L3大于L4，陶瓷套筒3才能够通过保持件4的第三开口43的宽度方向，放入到容纳腔。
在一些实施例中，如图13所示，光纤适配器还包括阻挡件6，与壳体2一体成型，阻挡件6包括位于保持件4的一端的第一阻挡件61和位于保持件4的另一端的第二阻挡件62；其中，第一阻挡件61具有与第一开口421连通的第一通孔611，第二阻挡件62具有与第二开口422连通的第二通孔621。具体的，前面已提到，陶瓷套筒3不能移动超出容纳腔41，可以在保持件4的长度延伸方向，在保持件4的两端设置阻挡件6用于限制移动，阻挡陶瓷套筒3从保持件4的两端滑出。阻挡件6与保持件4是一体成型结构，阻挡件6的形状结构任意，可以是如图14a所示的圆柱体形的圆环状结构，也可以是如图14b所示的圆台形的圆环结构。阻挡件6的大致中心区域开设有通孔，包括第一通孔611和第二通孔621，用于连接器陶瓷插针的插入。
在一些实施例中，如图13所示，第一通孔611和第二通孔621的孔径均小于陶瓷套筒3的外径。具体的，第一通孔611和第二通孔621的孔径可以相同，也可以不同，第一通孔611和第二通孔621中，尺寸最小的孔径应小于陶瓷套筒3的外径，可以阻挡陶瓷套筒3沿保持件4的轴向方向滑出。
在一些实施例中，如图15所示，保持盖板5的长度与长边431的长度相同。具体的，保持盖板5的面积大致覆盖保持件4的第三开口43，保持盖板5可以与保持件4保持较好的贴合，同时也可以为陶瓷套筒3提供遮 挡与保护。
在一些实施例中，如图16所示，保持盖板5具有相对的外表面和内表面，保持盖板5的内表面用于封闭第三开口43，保持盖板5的外表面与保持件的外表面平滑过渡。具体的，考虑到工艺的适配性与美观性，保持盖板5可以是弧形盖板，与保持件4连接后可与保持件4形成完整的圆柱体形结构。
在一些实施例中，如图15所示，光纤适配器还包括把手7，把手7设置在保持盖板5的外表面并与保持盖板5固定连接。具体的，设置把手7可以使保持盖板5在与保持件4在装配或者拆卸时更加便捷。
在一些实施例中，如图17和图18所示，把手7和保持盖板5均设置在空腔22内，与壳体2相邻。具体的，把手7和保持盖板5可以随保持件4一同设置在第一空腔221内，壳体2可以给把手7提供一定的夹持作用，使其卡固于壳体2。
以上所述，仅为本申请的较佳实施例而已，并非用于限定本申请的保护范围。
