Description

一种连接器和光纤连接组件 技术领域
本发明涉及光纤通信领域，具体涉及一种连接器和光纤连接组件。
背景技术
随着FTTH(Fiber To The Home，光纤到户)的大规模部署，减少施工成本，降低施工技术要求，简化施工难度的预连接产品应用越来越广。然而，现阶段使用的光纤连接器和适配器绝大部分采用的是行业标准型的连接器及适配器。该类型的连接器及适配器的设计初衷在于解决室内或者有保护盒(箱体)内的光纤连接，开通业务时需要打开盒体，在盒体里进行熔接，固定光缆等操作。为避免开通业务时开箱，熔接，固定光缆等动作，通常会选择使用具有较好的防水性能，可预装在盒体外使用的光纤连接器和适配器。
目前，市面上存在的室外型光纤连接器和适配器，大部分采用的锁紧方式为旋拧式，而旋拧式锁紧方式由于其自身特性，需要在连接器和适配器周边预留手指操作空间，在有限的安装空间下，特别是在密度要求较高的情况下，操作非常困难。部分插拔方式的连接器与适配器，受到本身结构的限制，光纤连接器轴向的拉伸力很难满足需要。
发明内容

两个延伸壁，其设于所述连接器外套的内壁，并朝所述连接器外套的轴向延伸，且两个延伸壁间隔设置以形成供所述延伸部通过的通道。
一些实施例中，
所述插入部上还设有第三凸起，所述弹性件一端抵持在所述环形本体上，另一端抵持在所述第三凸起上。
一些实施例中，所述连接器还包括：

具体实施方式
以下结合附图及实施例对本发明作进一步详细说明。
本发明实施例提供一种连接器，值的说明的是，连接器根据其插芯的不同，分为多种形态，具体可为MPO型、SC型或双LC型等。
参见图1至图4所示，本发明实施例中将会分别针对MPO型和SC型的连接器进行说明。对于MPO型和SC型的连接器，其均包括连接器主体10、弹性件11、解锁环12、连接器外套13、拉绳14、连接器帽15、连接器尾套16、连接器热熔管17、连接器前套18、顶持件19、插芯40、插芯弹簧41、插芯防尘帽42和连接器光缆50。
参见图5和图6所示，在本实施例的连接器中，连接器主体10包括插入部101，插入部101主要用于和匹配的适配器进行对接。所述插入部101上设有用于与匹配的适配器卡接的第一凸起102。在本实施例中第一凸起102具备两个相反的斜面、或弧面、或球面。
在连接器主体10尾部设有连接器尾套16，连接器主体10与连接器尾套16可以是两个独立零件也可以一体成型，本实施例中MPO型和SC型连接器均展示的是独立零件的情形。连接器尾套16外周设有压接环60，通过压接钳，将连接器光缆50内部的芳纶纱或加强芯压接固定，从而实现连接器光缆50的固定，再通过连接器热熔管17进行再次的固定和密封，作为连接器后端的光缆固定压接结构和防水防尘的密封结构。此外，在连接器尾部还设有尾护套30，用于保护连接器光缆50不受弯折损坏。
连接器主体10头端设有连接器前套18，连接器主体10与连接器前套18可以是两个独立零件也可以一体成型。MPO型连接器展示的是为独立零件的情况，SC型连接器展示的是为一体成型的情况。
连接器主体10、连接器尾套16、连接器前套18共同形成的空腔内设有顶持件19，顶持件19与连接器尾套16可以是两个独立零件也可以一体成型，顶持件19内部形成空腔，可穿过光纤。顶持件19与连接器前套18形成的空间内安装有插芯40以及插芯弹簧41，插芯弹簧41一端与插芯40抵持，另一端与顶持件19端面抵持。在插芯40前端设有插芯防尘帽42。其中插芯40可为单芯插芯、双芯插芯或多芯插芯，在图1中，展示的为MPO型多芯插芯，在图2中，展示的为SC型单芯插芯。
弹性件11套设在所述插入部101上。作为一个优选地实施方式，本实施例中的弹性件11可以是弹簧。
解锁环12套设在所述插入部101上，并可沿所述插入部101的轴向移动，所述解锁环12用于在与适配器卡接时，压缩所述弹性件11，并使所述弹性件11提供驱动解锁环12压持卡接处的驱动力。
连接器外套13套设在所述插入部101上，所述连接器外套13可沿所述插入部101的轴向移动，并可驱使所述解锁环12压缩所述弹性件11，以使所述解锁环12脱离所述卡接处。
参见图7所示，作为一个较好地实施方式，所述连接器外套13上设有外套凸起131，所述插入部101上设有用于限位的与所述外套凸起131匹配的第二凸起103。从而，通过第二凸起103和外套凸起131的共同作用，可以将连接器外套13的滑动限定在一定范围内。
此外，在连接器主体10与连接器外套13配合面上设有第二密封环105，保证连接器主体10与连接器外套13之间的配合密封。
进一步地，参见图8所示，为了实现连接器与适配器卡接时解锁环12所起到的作用，本实施例中的所述解锁环12包括环形本体121和延伸部122。其中，环形本体121用于与所述外套凸起131配合， 以使所述解锁环12随所述连接器外套13移动并压缩所述弹性件11。延伸部122设置在所述环形本体121上，并朝所述环形本体121的轴向的一侧延伸，所述延伸部122用于与所述适配器配合，以使所述解锁环12随所述适配器移动，并用于在卡接到位时压持所述卡接处。
同时为了便于实现连接器和适配器的解锁，本实施例中的外套凸起131包括两个延伸壁，两个延伸壁设于所述连接器外套13的内壁，并朝所述连接器外套13的轴向延伸，且两个延伸壁间隔设置以形成供所述延伸部122通过的通道。
当向后拉动连接器外套13时，可通过外套凸起131的两个延伸壁带动解锁环12共同向后运动并压缩弹性件11。当外力释放时，弹性件11复位，可带动弹性件11和连接器外套13共同复位。可以理解的是，当有外力仅作用于弹性件11时，只有弹性件11会相对滑动，而连接器外套13不会运动。
优选地，为了进一步便于连接器和适配器的解锁，在所述连接器外套13上还设有拉绳14，当拉动拉绳14时，便可带动连接器外套13移动来实现解锁。
此外，为便于安装固定弹性件11，在所述插入部101上还设有第三凸起104，所述弹性件11一端抵持在所述环形本体121上，另一端抵持在所述第三凸起104上。
作为一个优选地实施方式，参见图9至图11所示，连接器1还包括连接器帽15，从而来作为插芯40的保护。连接器帽15前端设有连接器帽孔152，用于管道施工时的光缆牵引，连接器帽15上还设有第一密封环153，用于连接器帽15与连接器外套13配合处的防水防尘。连接器帽15通过连接器帽连接绳151与连接器主体10相连，防止掉落丢失。
与之对应的是，参见图12至图14所示，本发明实施例提供一种适配器2，适配器2一端与本发明的连接器1对接，另一端与标准连接器3对接。其中标准连接器3可为SC型、LC型或MPO型等，因而，适配器2据其兼容的标准连接器3种类不同，分为多种形态，具体可为MPO型、SC型、双LC型等。
参见图15和图17所示，对于MPO型适配器，其包括适配器主体20、第三密封环202、适配器帽21、适配器帽连接绳211、安装螺母22和平垫221。其中适配器主体20上设有用于和连接器1卡接的卡扣201，卡扣201具备两个相反的斜面、或弧面、或球面。
在适配器主体20和连接器1的对接端，设有适配器帽21和第三密封环202，用于适配器2的密封，另设有适配器帽连接绳211，用于连接适配器帽21和适配器主体20，防止适配器帽21丢失。
在适配器主体20和标准连接器3的对接端，设有安装螺母22，用于适配器的安装。在安装螺母22与适配器主体20的法兰结构之间，设有平垫221，用于适配器与箱体配合处的密封。
参见图16和图18所示，对于SC型适配器而言，除了包含MPO型适配器以上零件以外，在适配器主体20内还包含有陶瓷套管203、套管卡座204。其余结构和MPO型适配器类似，在此不在赘述。
参见图19至图22所示，下面对本发明中连接器和适配器的锁紧和解锁原理做出介绍：
当需要将连接器1和适配器2进行锁紧时，手持连接器外套13将连接器1插入适配器2过程中，当插入部101上的第一凸起102的斜面与适配器主体20上的卡扣201的斜面接触时，会推动卡扣201向外张开，随着插入深度增加，卡扣201的端面会与解锁环12的端面(延伸部122的最左端)抵持，并推动解锁环12向后压缩弹性件 11。当连接器1插入到位时，插入部101上的第一凸起102与适配器主体20上的卡扣201形成扣合，卡扣201形状复位，脱离与解锁环12端面的相互抵持，此时解锁环12将在弹性件11的作用力下向前运动，当运动到最大行程时，压紧适配器主体20上的卡扣201，因为收到解锁环12的压紧作用，卡扣201无法产生张开形变，从而保证牢固的抗拉力。
当需要将连接器1和适配器2进行解锁时，手持或者通过拉绳14向后拉动连接器外套13，连接器外套13内侧的外套凸起131带动解锁环12向后运动，当解锁环12脱离与卡扣201接触时。连接器主体10向后运动，并通过第一凸起102将卡扣201胀开，完成脱扣动作，继续拉动连接器1，直至连接器1与适配器2完成脱离接触，即完成全部的解锁过程。
综上所述，本发明中的连接器，其在设置解锁环12后，当连接器与适配器对接时，在弹性件11提供驱动力下，解锁环12将会牢牢压持在连接器与适配器的卡接处，使得适配器的卡扣201无法产生张开形变，从而保证牢固的抗拉力，能够满足大部分室外型预成端连接器所需要的锁紧力度。
同时，本发明还提供一种光纤连接组件，其包括连接器1和适配器2。
