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是本发明的多联光纤连接器的优选实施例的示意图；
图2是本发明的多联光纤连接器的优选实施例的分解示意图；
图3是本发明的多联光纤连接器的优选实施例中光纤连接器本体的示意图之一；

图5是本发明的多联光纤连接器的优选实施例中连接板的示意图；
图6是本发明的多联光纤连接器的优选实施例中卡箍的示意图。
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。
本发明的多联光纤连接器是指两个或两个以上光纤连接器本体并联形成的光纤连接的联合体。
如图1和图2所示，为本发明的多联光纤连接器的优选实施例，本实施例为一双联光纤连接器，该双联光纤连接器包括两个光纤连接器本体1，两个光纤连接器本体1并行设置，两个光纤连接器本体1的侧面相贴合或间隔一定的间隙。该双联光纤连接器包括嵌入所述光纤连接器本体1内的连接件，连接件3将两个光纤连接器本体固连在一起形成双联连接器，在本实施例中，连接件包括一连接柱2和一连接板3。
参看图3，光纤连接器本体1上设有通孔101，连接柱2穿过两个光纤连接器本体1上的通孔101将两个光纤连接器本体1连接在一起，连接柱2与通孔101过盈配合,也即连接柱2嵌入到连接器本体1内，连接柱2的长度等于或略小于两个光纤连接本体1的厚度之和。装配时，可以借助工具将连接柱2敲入到通孔101中，连接柱2优选金属材质制成，例如铝质合金或钢铁等，保证连接柱2具有很好的连接强度。需要理解的是，连接柱2的截面并不局限于圆形，连接柱2的截面也可以是矩形或多边形，此时通孔101的截面也相应的为矩形或多边形。连接柱2也可以设置多个，例如两个或两个以上，对应的每个光纤连接器本体1上的通孔101也对应的为多个，优选对角配置，这种状况下可以省去连接板3。
参看图4和图5，在本实施例中，光纤连接器本体1的尾端上设有由光纤连接器本体1的侧面贯穿光纤连接器本体1的通槽102，连接板3则插入在通槽102中，将两个光纤连接器本体1连接在一起，连接板3与通槽102过盈配合，连接板3的长度等于或略小于两个光纤连接器本体1的厚度之和。
在本实施例中，进一步，为了增强连接板3与通槽102的配合，在通槽102内设有定位块103，连接板3则相应的上设有与定位块103配合的缺口301，所述定位块103卡在缺口301内，这样可以有效防止连接板3有光纤连接器本体1上松脱。进一步,还可以在连接板3的缺口301的两侧边设置止退凸起302，止退凸起302抵在定位块103的两侧,可以进一步防止在使用过程中连接板3由通槽102中松脱。需要理解的是,连接板3也可以单独依靠缺口301与定位块103的配合将两个连接器本体1连接起来,此时连接板3与通槽102并一定需要过盈配合,可以是间隙或过度配合。
在本实施例中,光纤连接器本体1具有弹性扣臂11，为了方便对多联光纤连接器进行操作,该多联光纤连接器还包括一个用于将弹性扣臂11固联为一体的卡箍4。具体的,在本实施例中，弹性扣臂11的上表面设有定位凸柱111，弹性扣臂11的侧面设有倒扣112，卡箍4优选由弹性的金属片冲压而成，卡箍4包括由弹性材料制成的基板40，以及由基板40两端折弯而成的两耳片41，基板40上设有与定位凸柱111配合的定位孔401，耳片41设有与倒扣112配合的扣位411，倒扣112扣在扣位411中，定位凸柱111由定位孔401中穿出。卡箍4将两个光纤连接器本体1的扣臂11连在一起，既方便了操作，由增加了连接器的整体强度。需要理解的是卡箍4并不是该双联连接器中的必要部件。
需要理解的是，本发明的多联光纤连接器的光纤连接器本体的数目并不局限于两个，可以是多个，优选偶数个。
在本发明的多联光纤连接器中，由于连接件由光纤连接器本体的侧面贯穿光纤连接器本体将光纤连接器本体连接在一起，连接件嵌入连接器主体内，连接件不会占用额外的空间，使得本发明的多联光纤连接器的结构更为紧凑，可以提高光纤的连接密度，尤其适用于需要高密度光纤连接的应用场合。
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。
