光纤连接器插头组件、光纤连接器组件及通信设备
本申请要求于2020年10月29日提交中国国家知识产权局、申请号为202011183419.7、申请名称为“光纤连接器插头组件、光纤连接器组件及通信设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光通信领域，特别是一种光纤连接器插头、光纤适配器、连接器组件及通信设备。
背景技术
随着通信技术的发展，光纤传输被越来越多地运用到通信系统中。光纤到户网络中，在入户阶段，从机房引出的光纤通过光纤与入户光纤在通信设备(例如光纤盒)内通过光纤连接器插头实现对接，以实现将光网络铺设至各家各户。具体为光纤连接器插头插接在通信设备的光纤适配器中。随着通信设备的多样化设计，不同的通信设备可能具有不同型号的光纤适配器，因此针对各通信设备，均需要配备固定型号的光纤连接器插头。现有的光纤连接器插头的兼容性能较差，只能适配单一型号的光纤适配器，针对不同型号的光纤适配器，只能使用不同的光纤连接器插头，无法使用同一个光纤连接器转换为适配不同的光纤适配器的插头。
发明内容
本申请实施例提供一种光纤连接器插头组件，能够适配不同类型的光纤连接器，具有通过性，且能够避免资材浪费。
第一方面，本申请提供一种光纤连接器插头组件，包括连接器主件和至少两个套件，连接器主件包括插芯和主壳体，所述插芯包括前段和连接段，至少部分所述连接段位于所述主壳体的内部，所述连接段与所述主壳体定位连接，以在径向上固定所述插芯及在轴向上限制所述插芯移出所述主壳体，所述前段完全位于所述主壳体的外部；均呈套筒状和至少两个套件能够与所述主壳体可拆卸地连接以遮挡所述前段，可以理解为套件安装至主壳体后，可以遮挡前段。所述连接器主件选择性地与至少两个所述套件之一者连接构成光纤连接器插头；当至少两个所述套件之一者与所述连接器主件连接时，所述套件和所述前段之间形成插槽，当所述插芯插入光纤适配器的插芯套筒时，所述插芯套筒伸入所述插槽且所述插芯套筒的开口端位于所述插槽内，可以理解为，插芯套筒的前端均插入插槽，插芯套筒的径向尺寸与插槽的径向尺寸匹配，即二者的径向尺寸可以相等或者之间的尺寸差是为了满足加工公差和组装间隙，也就是说插槽除了容纳插芯，不容纳其它元件；不同的所述套件与所述连接器主件组合构成不同形态的所述光纤连接器插头，以适配不同形态的光纤适配器。
本申请通过设置一个连接主件和至少两个套件，通过连接器主件与不同的套件匹配构成不同形态的光纤连接器插头，可以匹配不同形态的光纤适配器，因此本申请提供的光纤连接器组件中的连接器能够兼容多种不同的光纤适配器的插口，作为光纤连接器插头的核心元件 的连接器主件具有复用性、通用性，能够避免资材浪费，降低了用户使用光纤连接器插头的成本。
一种可能的实现方式中，所述前段为陶瓷材质，所述连接段为非陶瓷材质。具体而言，前段用于与光纤适配器内的插芯套筒中的陶瓷插芯紧密配合，连接段为金属材质。本实施方式限定了插芯的陶瓷材质的前段外露在主壳体的外部，这样的连接器主件必须要与套件配合才能构成光纤连接器插头，当连接器主件不使用时，即不需要与任何的套件连接的情况下，连接器主件的前端需要安装一个防尘帽或牵引帽等类似的防护结构，以保护插芯的前段。
本申请通过将连接器主件设置为：可以与不同的套件组合构成不同形态的光纤连接器插头组件，连接器主件的靠近前端的部分，插芯的前段是外露的状态，可以理解为，插芯的前段的外围没有任何套件及包覆结构，这样，使得连接器主件可以更自由地匹配不同形态的套件，可以与更小尺寸的套件组装为一体构成小型化的光纤连接器插头。因此，本申请提供的光纤连接器插头组件的组合方式更灵活。假设连接器主件中的插芯的前段的外围已经固定了一个套筒结构，这个套筒的结构使得光纤连接器主件的尺寸不可能做到很小，因为套筒结构和插芯之间还需要有插槽空间，若这样的连接器组件再与其它的套件结合，就没办法实现更小尺寸的光纤连接器插头。
具体而言，连接段包括中段和后段，前段和后段均呈中心对称结构，后段用于固定光纤，中段包括第一限位结构和第一挡止结构，沿轴向方向，第一限位结构位于第一挡止结构和前段之间。第一限位结构用于在圆周方向上对插芯进行限位，即防止插芯相对主壳体旋转。第一限位结构包括第一平面，第一平面的设置只要能使中段成为非旋转对称的结构，即可以具有圆周方向上限位的作用。第一挡止结构为连接至第一限位结构的柱状结构，第一挡止结构包括第一限位面，第一限位面朝向插芯的前端面。在制作插芯的过程中，通过切割的方式，在圆柱状的实体的外表面切掉一块，同时形成第一平面和第一限位面。
一种可能的实现方式中，至少两个所述套件包括一体式套件，所述一体式套件包括前端面和后端面，所述插芯包括位于所述前段远离所述连接段的一端的前端面，所述一体式套件连接至所述连接器主件时，所述一体式套件的后端面与所述主壳体连接，所述插芯的前端面与所述一体式套件的前端面齐平，或者在轴向方向上所述插芯的前端面位于所述一体式套件的前端面和所述一体式套件的后端面之间。本实施方式通过一体式套件的前端面保护插芯前端面，能够避免插芯的前端面被刮碰，具体而言，一体式套件能够在周转、运输、以及与光纤适配器插拔的过程中，实现对于插芯的前端面的保护，在后续与对端连接器插头的插芯进行对接时，保证光信号能够稳定、可靠的在两者之间进行传输。
当一体式套件与连接器主件连接时，一体式套件内侧与插芯之间形成与光纤适配器的插芯套筒配合的插槽，具体为插槽用于收容插芯套筒的一端，插芯套筒的端面要伸入插槽内，藉此，使得一体式套件兼备保护插芯前端面及与光纤适配器配合的功能，一体式套件的外围无需要再设置其它的元件，一体式套件的外表面也是整个光纤连接器插头的外表面，一体式套件是设置在插芯前段外围的唯一结构件，本申请将设置在插芯外围的保护特征(一体式套件的前端面)和插拔配合特征(一体式套件的内表面与插芯间形成的插槽及一体式套件的外表面与光纤适配器内表面接触配合)集中在一体式套件上，这样可以使得光纤连接器插头的径向尺寸足够小，在通信设备的有限空间内，可以布置更多的光纤连接端口。
一种可能的实现方式中，所述连接器主件的所述主壳体包括主轴及设于所述主轴外表面 的密封结构、锁固部和滑动件，所述插芯连接至所述主壳体的前端；所述滑动件于第一位置和第二位置之间滑动连接至所述主壳体；沿所述主壳体的轴向方向，所述锁固部位于所述滑动件和所述插芯之间，所述密封结构位于所述锁固部和所述插芯之间；当所述连接器主件与所述一体式套件连接构成所述光纤连接器插头时，所述锁固部和所述滑动件用于与对应的光纤适配器配合，所述滑动件位于第一位置时，所述滑动件与所述锁固部配合共同锁住所述光纤适配器，所述滑动件位于所述第二位置时，实现所述光纤连接器插头与所述光纤适配器之间的解锁。本实施方式限定了一种用于室外的光纤连接器插头，通过密封结构和第一锁持结构的配合，使得光纤连接器插头的结构简化，只需要配置一个位于第一锁持结构和插芯之间的密封结构，有利于使光纤连接器插头实现小型化的结构，而且第一锁持结构通过直插的方式与光纤适配器配合，使得光纤连接器插头可以具有很小的操作空间，减少了光纤连接器插头的空间占用率。
一种可能的实现方式中，所述滑动件与所述主壳体之间形成锁持槽，所述锁持槽用于与所述光纤适配器的弹性臂配合，所述锁持槽的开口位置位于所述滑动件的一端和所述主壳体之间，所述滑动件包括形成于所述锁持槽内壁的配合面，所述配合面朝向所述主壳体，所述配合面包括第一区域和第二区域，所述第一区域位于所述第二区域和所述锁持槽的开口之间，所述第一区域与所述主壳体之间的垂直距离大于所述第二区域与所述主壳体之间的垂直距离；当所述滑动件位于所述第一位置时，所述第一区域与所述锁固部相对设置，所述第二区域与所述主壳体的外表面相对设置，当所述滑动件位于所述第二位置时，所述配合面与所述主壳体的外表面相对设置。本实施方式通过将第一区域和第二区域与主壳体之间垂直距离设置为不同的方式，将配合面设计为类似双台阶或相对轴向方向倾斜延伸的结构，配合面与第二锁持部配合的状态下，配合面将第二锁持结构的弹性臂抵压在锁持槽内，第一区域和第二区域均对弹性臂产生抵压力，而且第一区域和第二区域在径向方向上构成双台阶或倾斜延伸的架构，不但有利于增加配合面和弹性臂之间的接触面积，还实现了径向扣压弹性臂的作用，对弹性臂的扣合及压持力能够保证弹性臂被稳固地锁持在锁持槽内，不易被拉出。
一种可能的实现方式中，配合面在轴向上的延伸的尺寸为第一尺寸，第一区域在轴向上的延伸尺寸为第二尺寸，显然第二尺寸小于第一尺寸，甚至第二尺寸可又小于第一尺寸的二分之一。在锁持状态下，配合面和弹性臂之间相互抵压区域可以为整个配合面所在的区域。而在解锁的过程中，只需要将第一区域移动至锁持状态下的第二区域所在的位置，第二区域同步移动至弹性臂之外，此时，第一区域和第二区域均与弹性臂之分离，弹性臂未被抵压，即实现了解锁。可见，解锁过程中，滑动件移动的行程只需要为第二尺寸的距离，不需要移动第一尺寸的距离。因此，本实施方式具有锁持稳固，轻松解锁的优势。
一种可能的实现方式中，当所述滑动件位于所述第一位置时，所述第一区域与所述锁固部相对设置，所述第二区域与所述主壳体的外表面相对设置，当所述滑动件位于所述第二位置时，所述配合面与所述主壳体的外表面相对设置。本申请通过限定滑动件于第一位置和第二位置时与主壳体的对应位置关系，能够保证滑动件在主壳体上的精确的定位，能提升锁持及解锁的效率。
一种可能的实现方式中，所述配合面呈阶梯状，第一区域在滑动件上从前端面朝向后端面的方向的延伸方向与滑动件的中心轴平行。
一种可能的实现方式中，所述配合面呈斜面状，第一区域在滑动件上从前端面朝向后端 面的方向的延伸方向与滑动件的中心轴之间形成夹角。
一种可能的实现方式中，至少两个所述套件还包括组装式套件，所述组装式套件的外表面的径向尺寸大于所述一体式套件的外表面的径向尺寸。本实施方式中，连接器主件可以连接一体式套件，也可以连接组装式套件，从而形成径向尺寸不同的光纤连接器插头，适配不同尺寸的光纤适配器，通用性更佳。
一种可能的实现方式中，所述组装式套件包括均呈套筒状的中间件和插接件，所述组装式套件连接至所述连接器主件时，所述中间件环绕所述前段，当所述组装式套件与所述连接器主件连接时，所述中间件和所述前段之间形成所述插槽，所述插接件套设在所述中间件的外围，所述插接件用于所述光纤适配器配合，以将所述光纤连接器插头组件连接至所述光纤适配器对接。本实施方式通过组装式套件的中间件与连接器主件配合，中间件用于与插芯之间形成插槽，以与光纤适配器的插芯套筒配合。通过插接件连接至连接器主件，插接件用于与光纤适配器的连接结构配合，以实现光纤连接器插头和光纤适配器之间的插接、锁持。插接件上可以集成导向结构和锁持结构，以及插接件还可以具有保护插芯前端面的功能结构。
一种可能的实现方式中，所述组装式套件的数量为至少两个，不同的所述组装式套件中的所述中间件的形态可以相同也可以不同，不同的所述组装式套件的所述插接件的形态是不同的。可以将中间件作为不同的组装式套件之间通用的标准件，可以理解为，不同的组装式套件的中间件可以是相同的，在替换不同的组装式套件时，只需要替换插接件即可，不同的组装式套件可以使用同一个中间件。
一种可能的实现方式中，所述插接件包括外套筒和导向筒，所述外套筒连接至所述导向筒的外围且环绕所述导向筒，所述导向筒套设在所述中间件的外围，且所述导向筒与所述连接器主件上的滑动件配合，以将所述插接件连接至所述连接器主件。本实施方式中的插接件由两个筒状结构构成，其中导向筒用于导向及保护插芯，外套筒与光纤适配器连接，实现锁持，外套筒可以套在光纤适配器的外围，与光纤适配器外围上的相关的结构配合。
一种可能的实现方式中，所述导向筒包括限位凸环和限位段，所述限位凸环位于所述限位段的一端，所述限位段包括沿轴向延伸且沿周向间隔布置的第一弹臂和第二弹臂，所述第一弹臂设有径向外突的卡勾结构，所述第二弹臂设有径向内突的卡持部，所述卡勾结构和所述限位凸环共同作用固定所述插接件，所述卡持部用于与所述滑动件的所述锁持槽及所述配合面配合，以实现将所述插接件连接至所述连接器主件。本实施方式通过导向筒与连接器主件上的滑动件配合实现导向筒与连接器主件的固定连接。可见本申请中连接器主体上的滑动件具有多功能性，当连接器主件与一体式套件配合的状态，滑动件用于与光纤适配器配合实现锁持，当连接器主件与本实施方式中的组装式套件配合的状态，滑动件可以与导向筒配合，用于锁固导向筒。可见，本申请提供的连接器主件具有通用性。
一种可能的实现方式中，所述插接件为一体式的筒状结构，所述插接件滑动连接至所述中间件且环绕所述中间件，所述插接件设有挖空区，所述中间件的外表面设有卡持部，所述卡持部对应设置在所述挖空区位置处，所述卡持部用于光纤适配器的卡勾配合，实现锁持状态，通过所述插接件相对所述中间件的轴向滑动，带动所述卡持部脱离所述光纤适配器的卡勾，以实现解锁。本实施方式提供的插接件为一体式结构，通过光纤适配器与中间件上的卡持部配合进行光纤连接器插头组件和光纤适配器之间的锁持，通过插接件的滑动实现解锁。本实施方式具有结构简单的优势，可以实现光纤连接器插头组件的小型化设计。
一种可能的实施方式中，所述插接件为一体式的筒状结构，所述插接件固定连接至所述连接器主件，所述插接件包围部分所述中间件，其余的部分所述中间件位于所述插接件的外部，所述插接件包括用于与所述光纤适配器连接的外螺纹。具体而言，位于插接件外部的部分中间件上设有导向结构，用于与光纤适配器插接过程的导向。位于插接件外部的部分中间件的外表面设密封结构，通过此密封结构实现中间件与光纤适配器之间的密封连接。所述中间件与所述连接器主件之间易设密封结构。

轴向方向：可以理解为光纤连接器插头的轴向方向，等同于光纤和插芯的延伸方向，即光纤的尾部延伸至光纤的前端再继续延伸至插芯前端的方向，等同于光纤连接器插头中的套设在光纤外围的壳组件的轴向方向。
径向方向：垂直于轴向的方向。
套筒状：套在长条状物体的外表面，起保护、加强固定或连接作用，具有套筒状的元件包括筒状(或管状)外壳，外壳内呈为中空空间，筒状(或管状)外壳的两个端面均设开口，长条状物体可以通过这两个开口穿过套筒状元件，例如光纤从壳组件的一端开口伸入壳组件，并能够从壳组件的另一端开口伸出壳组件。套筒状元件的端面包括内边缘和外边缘，套筒状元件的内表面连接在两个端面的内边缘之间，且朝向其内部的中空空间，套筒状元件的外表面为连接在两个端面的外边缘之间，朝向套筒状元件外部空间。套筒状元件的轴向方向为从其一个端面向另一个端面延伸的方向，其径向方向为从内表面向外表面垂直延伸的方向，可以理解为垂直于其轴向方向。套筒状元件的横截面的外轮廓可以为圆形、多边形、三角形或其它规则或不规则的形状，本申请不做限制。
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请提供的光纤连接器插头组件及通信设备应用在FFTx系统，FFTx系统可以为但不仅限于为FFTH(fiber to the home，光纤到户)、FFTC(fiber to the curb，光纤到路边)、FTTP(fiber to the premises，光纤到驻地)、FTTN(fiber to the node or neighborhood，光纤到节点)、FTTO(fiber to the office，光纤到办公室)、FTTSA(fiber to the servicearea，光纤到服务区)。本申请的实施例中，以通信设备应用至光纤到户(fiber to the home，FTTH)系统为例进行说明。参阅图1，图1所示为FTTH网络的示意图，在中心机房(Central Office，CO)1和用户终端盒(Customer Splicing Point，CSP)4之间设有预连接配线点(Connectorised Fiber Distribution Point，CFDP)2和分纤盒3，中心机房1内的通信设备通过光缆连接至预连接配线点2，将信号分配至预连接配线点2，预连接配线点2通过光缆将信号输送至分纤盒3，再通过分纤盒3输出(通过光缆传输)至用户终端盒4。
本申请提供的通信设备可以为但不仅限于为光纤分纤箱(fiber access terminal，FAT)、光缆接头盒(splitting and splicing closure，SSC)。
图2所示为一种实施方式提供的通信设备1000的示意图，通信设备1000包括外壳400、适配器组件200A、室内连接器组件300A和室外连接器组件100A。适配器组件200A固定于外壳400，室内连接器组件300A收容于外壳400的内部，室外连接器组件100A位于外壳400外部，且室外连接器组件100A和室内连接器组件300A能够通过适配器组件200A的连接而实现对插，进而实现光信号的传输。
应当理解，室内连接器组件300A和室外连接器组件100A的区别在于各自使用场景的不同，室内连接器组件300A可理解为位于外壳400内部而处于一个相对封闭的空间内，能够有效将外界灰尘、水汽等隔绝。室外连接器组件100A可理解为位于外壳400外部而处于一个相对开放的空间内，需具备较佳的环境适应能力以应对复杂多变的外界环境。
具体而言，外壳400包括盒体401和盖合于盒体401上的顶盖402，盒体401设有多个并排设置的插口4011，插口4011可以排列为一排，或多排。适配器组件200A包括多个光纤适配器200，光纤适配器200的数量等于或小于插口4011的数量(小于的情况表示，部分插口可以预留为其它用途)。其它实施方式中，插口4011也可以设置在顶盖402上。每一光纤适配器200均能够对应设置在相应插口4011的位置处。
室内连接器组件300A包括多个室内光纤连接器插头300，多个室内光纤连接器插头300均收容于外壳400内。另外，室内光纤连接器插头300的数量与光纤适配器200的数量相同，也可以少于光纤适配器200的数量，从而使得每一室内光纤连接器插头300均能与对应的一 个光纤适配器200插接。
室外连接器组件100A包括多个室外光纤连接器插头100，室外光纤连接器插头100的数量与光纤适配器200的数量可以相同，也可以少于光纤适配器200的数量，每一室外连接器插头100可以从外壳400的外部与对应的一个光纤适配器200插接。
可以理解的是，光纤适配器200的两端分别设有一个与室内光纤连接器插头300适配和一个与室外光纤连接器插头100适配的开口，室内光纤连接器插头300和室外光纤连接器插头100分别插接在光纤适配器200的两个开口中，使得室内光纤连接器插头300和室外光纤连接器插头100的插芯在光纤适配器200中对接，即实现两个需要连接的光纤的对接，以使发射光纤输出的光信号能最大限度地耦合到接收光纤中。
由此，各室内光纤连接器插头300和各室外光纤连接器插头100能够分别从外壳400的内部和外部，与对应的光纤适配器200插接，进而使得每一室内光纤连接器插头300均能和对应的室外光纤连接器插头100实现对插，以实现一条光信号的链路传输。
本申请提供的光纤连接器插头组件可以包括图2所示实施方式的通信设备1000中的室外光纤连接器插头100，也可以包括图2所示实施方式的通信设备1000中的室内光纤连接器插头300。接下来以室外连接器插头的具体实施方式来对本申请提供的连接器组件具体的架构进行详细描述。
本申请提供的光纤连接器插头组件包括连接器主件和至少两个套件，至少两个套件中的任意一个均可以与连接器主件组合形成一个光纤连接器插头，不同的套件与连接器主件可以构成不同的光纤连接器插头，不同的光纤连接器插头用于匹配不同型号的光纤适配器。本申请提供的光纤连接器组件和至少两个光纤适合器构成光纤连接器组件。光纤连接器组件可以应用在一个通信设备中，可以理解为一个通信设备内可以包括至少两种结构形态不同的光纤适配器。当然，光纤连接器插头组件也可以单独应用在一个通信设备中，可以理解的是，通信设备内的光纤适配器为一种型号，即一种结构形态，本申请提供的光纤连接器插头组件中的连接器主件和其中一个套件构成的光纤连接器插头可以应用在此通信设备中，而连接器主件与其它的套件组合后形成的光纤连接器插头可以使用至其它的通信设备中，使得本申请提供的光纤连接器插头组件可以通用于此通信设备与其它的通信设备。
参阅图3，图3示意性地描述了本申请的设计思想，即一个连接器主件可以匹配不同的套件，构成不同形式的光纤连接器插头，以匹配不同的光纤适配器。如图3所示，最右侧的为连接器主件100－1，连接器主件100－1左侧布置有套件100－2和牵引帽100－5，套件100－2包括四个形态不同的套件(套件的数量不限为四个，也可以为两个、三个或者更多个)，套件100－2的左侧为适配器组100－3，适配器组100－3包括四个形态不同的光纤适配器(同样，光纤适配器的数量也不限为四个，也可以为两个、三个或者更多个)，适配器组100－3的左侧为和对端光纤连接器插头组100－4，对端连接器插头组100－4包括四个对端光纤连接器插头，它们的结构可以相同，也可以不同，根据光纤适配器的结构选择匹配的对端光纤连接器插头。
连接器主件100－1包括插芯12和主壳体22，所述插芯12包括前段123和连接段127，至少部分所述连接段127位于所述主壳体22的内部，当然也可以全部的连接段127都位于主壳体22的内部。所述连接段127与所述主壳体22定位连接，以在径向上固定所述插芯12及在轴向上限制所述插芯12移出所述主壳体22，所述前段123完全位于所述主壳体22的外 部。所述前段123为陶瓷材质，所述连接段127为非陶瓷材质，例如连接段127为金属。
图3所示的实施方式中，套件100－2包括一个一体式套件21和三个组装式套件21A、21B、21C。适配器组100－3包括四个光纤适配器200－1、200－2、200－3、200－4。对端光纤连接器插头组100－4包括四个对端光纤连接器插头300－1、300－2、300－3、300－4。
一体式套件21为一体式结构，一体式套件21可拆卸连接至连接器主件100－1的主壳体22，以遮挡插芯12的前段123。一体式套件21与连接器主件100－1连接后构成光纤连接器插头，通过一体式套件21与光纤适配器200－1对接。
组装式套件21A、21B、21C均为分体式结构且均包括中间件和插接件，例如：组装式套件21A包括中间件21A－1和插接件21A－2，组装式套件21B包括中间件21B－1和插接件21B－2，组装式套件21C包括中间件21C－1和插接件21C－2。中间件21A－1、21B－1、21C－1能够可拆卸连接至连接器主件100－1的主壳体22且环绕插芯12的前段123的外围。插接件21A－2、21B－2、21C－2用于套在对应的中间件21A－1、21B－1、21C－1的外围，并用于与对应的光纤适配器200－2、200－3、200－4对接。各组装式套件21A、21B、21C中，中间件21A－1、21B－1、21C－1的形态可以是相同的，插接件21A－2、21B－2、21C－2的形态不同，通过不同形态的插接件21A－2、21B－2、21C－2与连接器主件100－1构成不同形态的光纤连接器插头，以匹配不同形态的光纤适配器200－2、200－3、200－4。组装式套件21A、21B、21C的外表面的径向尺寸大于一体式套件21的外表面的径向尺寸，一体式套件21具有小尺寸，一体式套件21上集成了组装式套件21A、21B、21C的中间件21A－1、21B－1、21C－1和插接件21A－2、21B－2、21C－2两部分的功能，可以提供一种小型化的光纤连接器插头，适配小尺寸的光纤适配器200－1。
图3所示的实施方式可以构成四种连接方案，具体如下：
第一种方案为：连接器主件100－1与一体式套件21组装成的光纤连接器插头与光纤适配器200－1配合，对端光纤连接器插头300－1与光纤适配器200－1配合。
第二种方案为：连接器主件100－1与组装式套件21A组装成光纤连接器插头与光纤适配器200－2配合，对端光纤连接器插头300－2与光纤适配器200－2配合。

第四种方案为：连接器主件100－1与组装式套件21C组装成光纤连接器插头与光纤适配器200－4配合，对端光纤连接器插头300－4与光纤适配器200－4配合。
接下来分别对上述四种方案的具体实施方式展开描述。
第一种方案中，一体式套件21和连接器主件100－1所构成的光纤连接器插头的一种具体的实施方式的详细描述如下。
参阅图4、图5、图6和图7，图4为一体式套件21和连接器主件100－1所构成的光纤连接器插头的立体组装示意图，图5为图4所示的光纤连接器插头的立体分解示意图，图6和图7分别为光纤连接器插头的不同方向的剖面图。本实施方式中，光纤连接器插头包括传输件10、壳组件20、密封结构30、滑动件40、第一弹性件60和第二弹性件70，壳组件20套设在传输件10的外围，用于保护传输件10及用于插拔光纤连接器插头。滑动件40滑动连接至壳组件20的外表面，用于光纤连接器插头与对应的光纤适配器的锁持和解锁。密封结构30设于壳组件20的外表面，且于轴向方向上位于滑动件40的前端，密封结构30用于 与光纤适配器的内表面密封连接。对于光纤连接器插头而言，前端表示与光纤适配器插接的一端(可以理解为插芯所在的一端)，尾端或后端指的是远离插芯的一端。
参阅图5、图6和图7，传输件10包括为光纤11和插芯12，插芯12连接至光纤11的前端。壳组件20包括前框套21(前框套为图3所示的一体式套件21，为了方便描述，在本实施方式中，统一称一体式套件为前框套)和主壳体22，如图6所示，主壳体22和传输件10共同构成连接器主件100－1(即图6中的主壳体22和传输件10组装后即为图3所示的连接器主件100－1)。前框套21呈套筒状结构，环绕插芯12，即套设在插芯12的外围，当然前框套21的内部空间也可以容纳部分光纤11，前框套21用于保护插芯12且用于与光纤适配器(即图3所示的光纤适配器200－1)插接配合。主壳体22包括安装件221、固定件222、主轴223、固定座224、尾套225和热缩套管226，主壳体22整体呈套筒状，用于收容光纤11，主壳体22内的各组成部分也均呈套筒状，本实施方式通过六个元件组装连接形成主壳体22，各元件之间均为固定连接，因此其中某些元件可以为一体式结构，例如固定件222可以一体成型在主轴223的前端面，因此固定件222可以看作是主轴223的一部分。
参阅图5、图6和图7，光纤11包括纤芯111、包裹在所述纤芯111外围的加强层112及包裹在所述加强层112外围的外层113。部分所述纤芯111伸出加强层112且与所述插芯12固定连接，光纤部分所述加强层112未被所述外层包裹，还有部分外层也位于壳组件20内部。加强层112的材质可以为金属与非金属，金属材质的加强层112可以为钢丝，非金属材质的加强层112可以为FRP(纤维增强复合材料)，加强层112主要就是起到加强光纤抗拉及平衡。加强层112的外表面不如外层的外表面光滑，加强层112的外表面可以有凹凸的结构，类似齿状结构，加强层112外露(即不被外层包裹)的目的是加强层112可以与壳组件20进行固定连接。光纤11的纤芯111通过固化胶固定于插芯12。插芯12的详细结构描述如下。
参阅图8和图9，插芯12包括前端面121和后端面122，在前端面121和后端面122之间依次连接的前段123、中段124和后段125，其中，中段124和后段125共同构成插芯12的连接段127，前段123为陶瓷材质，前段123用于与光纤适配器内的插芯套筒中的陶瓷插芯紧密配合，连接段127为非陶瓷材质，例如金属材质。前段123和后段125均呈中心对称结构，例如后段125为圆柱状，前段123为圆柱状和圆台状的结合。中段124包括第一限位结构1241和第一挡止结构1242，沿轴向方向，第一限位结构1241位于第一挡止结构1242和前段123之间。第一限位结构1241用于与壳组件20配合，以在圆周方向上对插芯12进行限位，即防止插芯12相对壳组件20旋转。第一限位结构1241包括第一平面1243，第一平面1243的数量可以为一个、两个或更多，第一平面1243的设置只要能使中段124成为非旋转对称的结构，即可以具有圆周方向上限位的作用。如图8所示，第一平面1243的数量为四个，间隔且对称分布在中段124的外表面。第一挡止结构1242为连接至第一限位结构1241的柱状结构，第一挡止结构1242包括第一限位面1244，第一限位面1244朝向插芯12的前端面121，本实施方式中，第一限位面1244的数量亦与第一平面1243的数量对应设置，且第一限位面1244与第一平面1243垂直连接。在制作插芯12的过程中，通过切割的方式，在圆柱状的实体的外表面切掉一块，同时形成第一平面1243和第一限位面1244。后段125的外表面用于套设第一弹性件60(例如弹簧)，第一挡止结构1242朝向后段125的表面为定位面1245，此定位面1245用于抵接第一弹性件60。后段125内设纤芯固定孔1251，纤芯固 定孔1251在后端面122上形成开口，用于供纤芯111插入，纤芯固定孔1251的底部和插芯12的前端面121之间形成通光孔126，底部指的是纤芯固定孔1251内正对开口的位置。
光纤连接器插头在光纤适配器内与对端光纤连接器插头对接时，通过插芯12的前端面121对接，实现两个光纤连接器插头之间的光信号传输。因此，对于光纤连接器插头而言，插芯12前端面121需要被壳组件20保护，以保证插芯12的前端面121不被刮碰，保证光传输的质量。
本实施方式通过壳组件20上前框套21可以实现对插芯12前端面的保护。前框套21的详细描述如下(参阅图10至图17进行描述)。
参阅图10、图11，前框套21呈套筒状，包括前端面211和后端面212。结合图4至图6，在光纤连接器插头中，前框套21位于壳组件20的最前端，前框套21的后端面212用于连接至主壳体22。
参阅图12，一种实施方式中，前框套21的前端面211与插芯12的前端面121齐平。参阅图13，另一种实施方式中，插芯12的前端面121被前框套21的内表面包围，即插芯12的前端面121缩入前框套21内部，前框套21的前端面211在轴向方向上突出于插芯12的前端面121设置，在轴向方向上，插芯12的前端面121和前框套21的前端面211之间的距离为L，本实施方式也可以理解为：所述插芯12的前端面121在所述前框套21上的垂直投影位于所述前框套21的前端面211或者所述前框套21的内表面，藉此，实现对插芯12前端面的保护。图12和图13的实施方式中，前框套21的前端面11均可以对插芯12的前端面形成保护。具体而言，前框套21能够在周转、运输、以及与光纤适配器插拔的过程中，实现对于插芯的前端面的保护，在后续与对端连接器插头的插芯进行对接时，保证光信号能够稳定、可靠的在两者之间进行传输。
参阅图12和图13，前框套21的内表面和插芯12之间形成插槽217，插槽217在前框套21的前端面211和插芯12的前端面121之间形成开口，插槽217用于与光纤适配器的插芯套筒配合，即当光纤连接器插头插入光纤适配器时，插芯插入插芯套筒内部，同时插芯套筒插入此插槽217中，插芯套筒的一端都要伸入插槽217内，即插芯套筒的端面位于插槽217内，且与插槽217的槽底部相对设置，插槽217的槽底部指的是插槽217的开口相对的一端。
图10所示的实施方式中，所述前框套21上靠近前端面211的位置处设两个相对设置的缺口G1，G2，前框套21的前端面211形成于所述两个缺口G1，G2之间，即前端面211包括第一面211A和第二面211B，第一面211A和第二面211B分对称设置在前框套21的中心轴的两侧。具体而言，若将第一面211A和第二面211B连起来构成一个完成的圆环形，第一面211A和第二面211B均小于等于四分之一个圆环形，以使这两个缺口G1，G2的位置可以容纳另一个光纤连接器插头上的前框套的前端面所在的部分侧壁，可以理解的是，当相同的光纤连接器插头对插在同一个光纤适配器中时，由于前框套21的前端面突出于插芯12的前端面211，两个插芯12需要对接，两个前框套21就需要有干涉配合，这两个缺口G1，G2就是为了解决这种对接干涉配合的问题，两个缺口G1，G2的位置，可以容纳另一个前框套21的前端面211所在的部分区域。
具体而言，两个缺口G1，G2可以对称设置在前框套21中心轴的两侧，对称设置的形态使得外观套在插接时所受力能够较为均匀和平衡，外框套整体的强度高，能够将因力不均衡而导致连接失效的可能性降低到最小。
图10至图13所示的实施方式中，所述前框套21的外表面设有第一导向结构213，第一导向结构213沿轴向方向延伸，第一导向结构213可以从前框套21的前端面211延伸至前框套21的后端面212，也可以从前框套21的前端面211延伸至前框套21的中部位置，此中部位置指的是位于前端面211和后端面212之间的位置，不只是代表前端面211和后端面212的中心位置，可以为靠近前端面211的位置，也可以为靠近后端面212的位置。在径向方向上，第一导向结构213可以为凹设在所述前框套21的外表面的槽结构，即第一导向结构213未贯穿至前框套21的内表面。
在轴向方向上，第一导向结构213可以对应缺口G1或G2的位置设置，通过第一导向结构213和缺口G1或G2能够为光纤连接器插头的插接过程的对位提供醒目的提醒作用，从而便于光纤连接器插头与光纤适配器对准，提升插接对接的精准度，防止光纤连接器插头的插芯组件因光纤连接器插头的误插而被多次碰撞导致损伤、失效的问题发生，有效调高光纤连接器插头的使用寿命。
前框套21的外表面为圆柱状，由于外表面要与光纤适配器200－1插接配合及具导向结构，前框套21的外表面也是光纤连接器插头的外表面，光纤连接器插头未与光纤适配器插接的情况下，前框套21的外表面直接暴露在光纤连接器插头的外部，无其它元件遮挡前框套21。
一种实施方式中，参阅图11、图12和图13，前框套21的内表面设有第二限位结构214，用于与插芯12上的第一限位结构1241配合，以阻止所述插芯12在所述前框套21内转动。具体而言，前框套21包括连接在前端面211的中心位置和后端面212的中心位置之间的中心轴C1，第二限位结构214突出设置在前框套21的内表面，第二限位结构214包括第二平面2142，第二平面2142朝向中心轴C1，也可以理解为第二平面2142是第二限位结构214上背离前框套21的外表面一侧的表面。第二平面2142用于与插芯12的第一限位结构1241的第一平面1243配合。对于第一平面1243和第二平面2142，本申请不限定为理论上的平面特征，可以理解为第一平面也可以为接近平面，例如接近平面的弧形表面，或者第一平面和第二平面上也可以设有凹凸结构。
一种实施方式中，参阅图14，前框套21设有卡孔215，卡孔215为贯穿前框套21的内表面和外表面的孔状结构，卡孔215也可以为凹设在前框套21的内表面的卡槽结构。卡孔215用于固定主壳体22的安装件221。卡孔215的数量可以为一个、或两个、或多个，图14所示的实施方式中，卡孔215的数量为两个，且相对设置在前框套21的中心轴C1的两侧。
图10至图14所示的实施方式中，前框套21的后端面212设有第一切口216，第一切口216在前框套21的后端面212、内表面和外表面均形成开口，第一切口216用于与主壳体22上的突块2232配合，以在圆周方向上定位前框套21和主壳体22，防止前框套21相对主壳体22旋转。
本实施方式提供的前框套21的前端面211能够保护插芯12前端面121、前框套21的内表面能够与插芯12限位连接、前框套21的外表面用于与光纤适配器200－1的内表面配合且具第一导向结构213、前框套21的后端面与主壳体22对接定位。通过一个前框套21的结构实现多方面的功能，而且前框套21的外表面外露，即为光纤连接器插头的外表面，即插芯12外围只有一个前框套21结构件，本申请将设置在插芯12外围的保护特征(前框套21的前端面211)和插拔配合特征(前框套21内表面与插芯12间形成的插槽及前框套21的外表 面与光纤适配器内表面接触配合)集中在前框套21上，不但能够减少零件，简化光纤连接器插头的结构，还有利于径向尺寸的小型化设计。
前框套21的后端呈全包围筒状架构，即前框套21的后端呈周向封闭的架构，即使设置了第一切口216，在前框套21和主轴223组装后，第一切口216也被主轴223上的对应的突块填充，因此，组装后的光纤连接器插头上，前框套21的后端依然是全包围的周向封闭架构。一方面能提升前框套的结构强度，另一方面也能够提升前框套与主轴之间的连接强度，而且前框套作为光纤连接器插头的外观件，周向全封闭的结构能够带来外观完整性，提升用户体验感。
安装件221和前框套21在径向方向上层叠设置，前框套21套在安装件221的外围。安装件221的详细描述如下。

安装件221与前框套21之间的固定方式不限于通过弹性卡勾2212与卡孔215的配合固定，其它实施方式中，可以通过其它的方式固定，例如：安装件221也可以不设弹性卡勾2212，安装件221和前框套21之间可以通过螺丝固定，通过螺丝穿过前框套21并固定在安装件221内；或者，通过在前框套21上设置卡勾，在安装件221上设置卡槽或卡孔，通过卡勾与卡 槽或卡孔的配合固定安装件221和前框套21。
参阅图15、图16和图17，安装件主体2211的后端面2214设第二切口2218，第二切口2218在安装件主体2211的后端面2214、内表面和外表面均形成开口，第二切口2218用于实现安装件221与主轴223之间的定位，在圆周方向上定位安装件221和主轴223，防止安装件221相对主轴223旋转。参阅图18和图19，前框套21安装至安装件221上后，所述安装件主体2211的后端面2214和所述前框套21的后端面212共面且共同形成对接面S1，所述对接面S1与所述主轴223的端面对接。本实施方式通过对接面S1与主轴223端面对接的结构设计，使得前框套21与主轴223的连接只占用主轴223端面的空间，不会延伸至主轴223的外表面，而且本实施方式中，前框套21的外表面可以与主轴223的外表面共面，或圆滑过渡连接，例如前框套21的外表面为圆柱形表面，主轴223的外表面也是圆柱形表面，前框套21对接至主轴223的端面上时，这两个径向尺寸相同的圆柱形的外表面对接形成一个完整的圆柱形外表面。对接面S1与主轴223的端面通过切口和突块配合的结构实现周身向定位，具体为：所述第一切口216和所述第二切口2218于径向方向上正对，用于实现将所述前框套21和所述安装件221定位至所述主轴223。
对接面S1与主轴223的对接处可以形成密封连接，此密封连接的作用是使得主轴223内部的空间与外部空间密封隔绝，这样可以保护纤芯和插芯免受灰尘、水汽等侵蚀，提升光纤连接器插头的使用寿命，及光传输的效率和质量。

本实施方式中，中部2227的外围设有密封槽，用于收容密封件30，当然，本实施方式的架构下，中部2227的外围也可以不设置密封槽，而是将密封槽设置在主轴223的外表面，光纤连接器插头与光纤适配器插接时，中部2227位于光纤适配器的内部，主轴223的前端也伸入光纤适配器。
固定件222的后端2226与主轴223之间也可以设置密封结构。
可以理解的是，中部2227的外围也可以设置导向结构，此导向结构与前框套21上的第一导向结构213连通或连续延伸，共同与光纤适配器中的导向键配合。其它实施方式中，中部2227的外围和主轴223的外围均设置导向结构，这两导向结构均设置在前框套21上的第一导向结构213的延伸路径上，且与前框套21上的第一导向结构213共同形成光纤连接器插头的导向结构。
参阅图21B和图21A，图21B为图21A所示实施方式中的前框套21的一种实施方式的示意图，本实施方式中，前框套21包括主体218和弹臂219，图21B中只显示了一个弹臂219，可以理解的是，主体218上可以设置两个弹臂219，对称分布在主体218上。所述弹臂219包括相对的第一端2191和第二端2192，所述第一端2191连接至所述主体218，所述第二端2192设有卡勾2193，所述弹臂219还包括连接在所述第一端2191和所述第二端2192之间的第一侧边2194和第二侧边2195，所述第一侧边2194和所述主体218之间设有缝隙2196，所述第二侧边2195和所述主体218之间亦设缝隙2197，前框套21的弹臂219的第二端2192和主体之间形成锁扣孔2198。一种实施方式中，通过主壳体22上的卡扣221A与锁扣孔2198配合，或者通过主壳体22上的锁孔(或锁槽)221B与弹臂219上的卡勾2193配合，实现前框套21和主壳体22之间的可拆卸连接。主壳体22上的卡扣221A和锁孔(或锁槽)221B可以同时存在。如图21B所示，所述主壳体22上与前框套21配合的部分为安装件221。安装件221上设有卡扣221A锁孔(或锁槽)221B，其中，锁孔(或锁槽)221B为卡扣221A右侧的收容弹臂219上的卡勾2193的位置。所述卡勾2193与所述锁孔(或锁槽)221B配合，同时，卡扣221A扣合在锁扣孔2198内，以实现所述一体式套件和所述主壳体之间的锁持状态，所述弹臂219受外力张开时，使得所述卡勾2193脱离锁孔(或锁槽)221B，卡扣221A脱离锁扣孔2198，以实现所述一体式套件21和所述主壳体22之间的解锁。

参阅图27和图28，滑动件40的内表面还设有第二滑动导向结构44，第二滑动导向结构44用于与主轴223上的第一滑动导向结构2236配合。第二滑动导向结构44位于第二板件B2和第四板件B4的内表面。第二滑动导向结构44包括第二导向部441和第二限位部442，第二限位部441位于第二导向部442远离滑动件40前端面41的一侧，第二导向部441用于与主轴223外表面的第一导向部22361配合，第二限位部442用于与主轴223外表面的第一限位部22362配合，第二限位部442朝向滑动件40前端面的一侧形成第二限位台阶4421，所述第二限位台阶4421用于与所述主轴223上的第一限位部22362的第一限位台阶22363配合，以界定滑动件40朝向主轴223前端滑动的边界位置。第二限位部442和第二导向部441构成T状结构。本实施方式中，第二限位部442和第二导向部441为凹设在滑动件40内表面上的导槽结构，其它实施方式中，第二限位部442和第二导向部441也可以为突出滑动件40内表面设置的导轨结构。滑动件40的内表面设有朝向滑动件40后端面43的台阶定位面45，用于定位第二弹性件70。

将光纤11穿过主轴223和固定件222，将光纤11的前端的部分纤芯111插入插芯12的纤芯固定孔1251内，并通过固化胶将纤芯111固定至插芯12。

所述插芯12的前端面121与所述前框套21的前端面211齐平，或者在轴向方向上所述插芯12的前端面121位于所述前框套21的前端面211和所述前框套21的后端面213之间。也可以理解为：所述插芯12的前端面121在所述前框套21上的垂直投影位于所述前框套21的前端面211或者所述前框套21的内表面。
结合参阅图6和图7，将滑动件40前端面朝向主轴223的尾端(光纤要穿过滑动件40)，将滑动件40套在主轴223的外表面上，通过滑动件40内表面的第二滑动导向结构44与主轴223外表面的第一滑动导向结构2236的配合，实现滑动件40和主轴223在圆周方向上的定位，此实施方式中的第二滑动导向结构为凹槽结构，图7中标号44引线所指示的位置为凹槽的内壁，凹槽内容纳第一滑动导向结构2236。结合参照图27和图28，通过滑动件40的第二限位部442的第二限位台阶4421和主轴223外表面上的第一限位部22362的第一限位台阶22363的配合实现轴向方向上限定滑动件40和主轴223之间的位置。
将第二弹性件70套设在主轴223上，第二弹性件70的一端安装至滑动件40和主轴223之间的空间内且抵持至滑动件40内表面的台阶定位面45。
将固定座224安装至主轴223上的固定部2237，固定座224的前端抵持第二弹性件70的另一端，且固定座224部分伸入滑动件40和主轴223之间的空间内。此状态下，第二弹性件70处理压缩状态，通过弹力将滑动件40推顶在第一位置，即滑动件40的第二限位部442的第二限位台阶4421和主轴223外表面上的第一限位部22362的第一限位台阶22363 的配合的位置。
滑动件40能够在第一位置和第二位置之间滑动，第二位置可以通过主轴223上的限位结构确定，第二位置也可以没有确定的位置，只要在轴向方向上位于第一位置远离插芯的一侧即可。参阅图5，滑动件40与主轴223上的锁固部2235共同构成第一锁持结构L1，第一锁持结构L1用于与光纤适配器上的第二锁持结构配合，以将所述光纤连接器插头固定至所述光纤适配器。所述滑动件40位于第一位置时，所述滑动件40与所述锁固部2235配合共同锁住所述第二锁持结构；所述滑动件40位于所述第二位置时，实现所述锁固部2235与所述第二锁持结构之间的解锁。所述滑动件40的配合面42与所述主壳体22的外表面之间形成锁持槽47，所述锁持槽47用于与所述第二锁持结构的弹性臂配合，所述锁持槽47的开口位置位于所述滑动件40的前端面41和所述主壳体22的外表面之间，可以理解为配合面42为锁持槽47的内壁，所述配合面42朝向所述主壳体22，第一区域421位于第二区域422和锁持槽的开口之间，所述第一区域421与所述主壳体22之间的垂直距离大于所述第二区域422与所述主壳体22之间的垂直距离。当所述滑动件40位于所述第一位置时，所述第一区域421与所述锁固部2235相对设置，所述第二区域422与所述主壳体22的外表面相对设置，当所述滑动件40位于所述第二位置时，所述配合面42(包括第一区域421和第二区域422)与所述主壳体22的外表面相对设置。
将滑动件40和固定座224安装至主轴223后，调整好光纤的位置，主轴223尾端B的通孔2238与光纤11的外露的部分加强层112对应，在主轴223尾端B的通孔1128处点胶，通过胶水实现光纤11的加强层112与主轴223内表面的固定，本实施方式通过在主轴223尾端B处设用于灌胶的通孔2238，通过灌胶的方式固定光纤，由于胶水填充加强层112和主轴223之间的间隙，还利用了加强层112本身的表面结构形态，加强层112表面具有灌胶空间，使得胶水可以充分接触光纤11和主轴223，提升固定效果，而且通过在主轴223上去除部分材料的方式，且在主轴223内部固定光纤，不占用主轴外部空间，有利于小型化的设计。而且，胶水填充在主轴223和光纤11之间，还能够实现二者之间的密封连接，不会因为通孔的设置导致密封效果不好。为了保证密封效果，将热缩套管226套在主轴223尾端B位置处，使得热缩套管226部分固定在主轴223的尾端的外表面，热缩套管226的另一部分固定在未伸入主轴223内的部分光纤11的外层113上。将尾套225固定在热缩套管226的外围，且尾套225的前端固定连接至固定座224后端的固定槽2242内。尾套225的外表面可以通过模印、激光打标等技术刻印一维条码，用于可视化识别。
将密封结构30套设在密封槽2234处，当光纤连接器插头插入光纤适配器内时，密封圈密封连接在主轴223和光纤适配器的内表面之间，本实施方式提供的光纤连接器插头为室外使用的光纤连接器插头，具有密封要求。本实施方式提供的主轴223的前端伸入光纤适配器200－1通过密封结构30实现密封，主轴223的尾端通过热缩套管226实现主轴223与光纤之间的密封连接，这样在主轴223上的前端位置只需要配置一级密封结构30，即可以实现光纤连接器插头和光纤适配器之间的密封连接。
与第一种方案提供的光纤连接器插头相配合的光纤适配器200－1的详细描述如下。
参阅图30和图31，光纤适配器200－1包括主体套筒201和插芯套筒202，所述插芯套筒202连接在所述主体套筒201的内部，插芯套筒202可以与主体套筒201为一体成型的结构。主体套筒201包括第一端面2011和第二端面2012，主体套筒201内部形成位于第一端 面2011内侧的第一容纳空间2013和位于第二端面2012内侧的第二容纳空间2014，第一端面2011设有供第一容纳空间2013与外界相连通的第一开口，第二端面2012设有供第二容纳空间2014与外界相连通的第二开口。插芯套筒202内设插芯收容空间2022，插芯收容空间2022连通在第一容纳空间2013和第二容纳空间2014之间。第一容纳空间2013用于收容一个光纤连接器插头，第二容纳空间2014用于收容另一个光纤连接器插头，所述插芯套筒202内的插芯收容空间2022用于收容两个光纤连接器插头的插芯。本实施方式提供的光纤适配器200－1中，第一容纳空间2013用于插接室外光纤连接器插头，第二容纳空间2014用于插接室内光纤连接器插头，第二容纳空间2013的内部结构及室内光纤连接器插头的具体架构，本申请不做限定。

参阅图31，所述第一段2051的外表面至所述主体套筒201的中心轴C6的垂直距离R1大于所述第二段2052的外表面至所述主体套筒201的中心轴C6的垂直距离R2。具体而言，部分卡槽204位于主体部203的内表面，部分卡槽204位于弹性臂205的内表面(具体为第一段2051的内表面)，在所述主体套筒201的径向方向上，所述第一段2051正对部分所述卡槽204，所述第二段2052位于所述卡槽204的外围。
一种实施方式中，如图31所示，所述弹性臂205的外表面呈阶梯状，即第一段2051和第二段2052之间形成台阶面。其它实施方式中，如图32所示，从所述主体部203至第二段2052远离主体部203的一端的延伸方向为弹性臂205的延伸方向，所述弹性臂205的延伸方向与主体套筒201的轴向方向之间形成夹角A6，图32示意性地表达了弹性臂205相较轴向方向倾斜延伸，具体倾斜的角度A6可以根据具体的光纤连接器插头的滑动件上的相关特征(即配合面)进行设置。
一种实施方式中，所述第一段2051的外表面和/或所述第二段2052的外表面设有蚀纹结构；或者，所述弹性臂205的外表面设有突出部，所述突出部用于与所述光纤连接器插头的所述滑动件40上的凹槽配合。
参阅图31和图32，主体套筒201的主体部203的内表面设有导向键206，本实施方式中，导向键206朝向第一收容空间2013内突出设置，导向键206用于与前框套21上的第一导向结构213配合，提供光纤连接器插头插入光纤适配器200－1过程中的导向。主体套筒201和插芯套筒202之间形成第一插槽207，所述第一插槽207用于收容光纤连接器插头中的前框套21，本实施方式提供的光纤适配器200－1通过主体套筒201和插芯套筒202之间的第一插槽207与光纤连接器插头100的前框套21的配合，以及主体套筒201内表面与前框套21外表面的接触配合，以及导向键206用于与前框套21上的第一导向结构213配合，实现光纤适配器200与光纤连接器插头的匹配，对于光纤适配器200－1而言，其结构简化，通过第 一插槽207和主体套筒201的内表面已经实现了对插入其中的光纤连接器插头的对位，径向尺寸可以设计为与光纤连接器插头的前框套21匹配，具有小尺寸的优势。
参阅图33，本申请提供的光纤适配器200－1还包括陶瓷套筒208，陶瓷套筒208安装在插芯套筒202的内部。陶瓷套筒208设有切口2082，切口2082沿轴向方向从陶瓷套筒208的一端延伸至另一端，切口2082的设置使得陶瓷套筒208的径向尺寸可调，可以实现陶瓷套筒208与插芯套筒202之间的紧密配合。陶瓷套筒208的内部空间用于收容插芯，具体而言，陶瓷套筒208用于夹持插芯12的前段123，插芯12的前段123的外径尺寸稍大于陶瓷套筒208的内径，这样前段123插入陶瓷套筒208内时，迫使陶瓷套筒208张开，使得陶瓷套筒208将前段123夹紧。
图34为第一种方案中，连接器主件100－1与一体式套件21组装后，插入光纤适配器200－1状态且处于锁持状态的剖面示意图，光纤适配器200－1的另一端插接对端光纤连接器插头300－1。图35为图34中的I部分的放大示意图，图36为图34中II部分的放大示意图。
图37为第一种方案中，连接器主件100－1与一体式套件21组装后，插入光纤适配器200－1状态且处于解锁状态的剖面示意图。图38为图37中的III部分的放大示意图。
图34中可以看到密封结构30在光纤适配器200－1内部实现光纤连接器插头与对应的光纤适配器200－1之间的密封连接。
如图36所示，光纤连接器插头与光纤适配器200－1对插后，光纤连接器插头的前框套21插入第一插槽207内，插芯12插入插芯套筒202内且被陶瓷套筒208包围，前框套21的外表面接触主体套筒201的内表面。
图34所示为光纤连接器插头与光纤适配器200－1对插后的锁持状态，如图35所示，其中滑动件40处于第一位置，光纤连接器插头的锁固部2235与光纤适配器的卡槽204配合，配合面42的第一区域421抵持在弹性臂205的第一段2051上，配合面42的第二区域422抵持在弹性臂205的第二段2052上，实现双台阶的锁持结构。
图37所示为光纤连接器插头与光纤适配器200对插后的解锁状态，如图38所示，其中，滑动件40处于第二位置，配合面42的第一区域421位于弹性臂205的第二段2052的外围，且第一区域421和第二段2052之间无抵持关系，第一区域421和第二段2052彼此分离且二者之间形成间隙，第二区域422正对光纤连接器插头的主轴223的外表面。由于配合面42和弹性臂205之间形成间隙，弹性臂205可以张开，因此，此时，虽然光纤连接器插头的锁固部2235位于光纤适配器的卡槽204内，仍然可以将光纤连接器插头从光纤适配器200－1中拔出。
图39和图40为第一种方案中的连接器主件100－1与一体式套件(即前框套21)组装构成的光纤连接器插头与牵引帽100－5配合的示意图。牵引帽100－5套在一体式套件(即前框套21)的外围，并与主壳体22固定连接，牵引帽100－5与主壳体22之间通过螺纹连接固定。牵引帽100－5的内表面与一体式套件(即前框套21)的外表面接触，亦与部分主壳体22的外表面接触，牵引帽100－5和主壳体22之间设有密封结构30。牵引帽100－5与主壳体22的连接强度大于一体式套件(即前框套21)与主壳体22的连接强度，因此，本实施方式通过牵引帽100－5与主壳体22的连接，可以在光纤连接器插头在穿管的场景中，对光纤连接器插头进行牵引及保护。也可以直接将牵引帽100－5组装至连接器主件100－1，即连接器主件100－1未组装一体式套件(即前框套21)，直接安装牵引帽100－5，通过牵引帽100－5将 连接器主件100－1进行穿管操作后，再拆下牵引帽100－5，然后将一体式套件(即前框套21)安装至连接器主件100－1。
第二种方案中，组装式套件21A和连接器主件100－1所构成的光纤连接器插头的一种具体的实施方式的详细描述如下。

参阅图44，外套筒21A－2A和导向筒21A－2B互连形成一体式的插接件21A－2结构，通过导向筒21A－2B的限位凸环B21和第一弹臂B221固定外套筒21A－2A，具体而言，外套筒21A－2A内表面的定位结构A21卡持在导向筒21A－2B限位凸环B21和卡勾结构B2211之间，第一定位面A211抵持于第三定位面B212，卡勾结构B2211卡持在第二定位面A212上的限位凹槽A2121内，即可以实现将外套筒21A－2A连接至导向筒21A－2B，具体而言，此种连接架构实现了外套筒21A－2A和导向筒21A－2B之间的轴向限位，在圆周方向上，外套筒21A－2A可以相对导向筒21A－2B旋转。外套筒21A－2A和导向筒21A－2B互连后，导向筒21A－2B的前端相对外套筒21A－2A突出且外露，外露部分的导向筒21A－2B用于方便在与光纤适配器对插的过程中的定位观察，操作者可以看到外露部分的导向筒21A－2B，容易实现插接过程的对位。可 以通过外力使第一弹臂B221向导向筒21A－2B内部空间张开，使得卡勾结构B2211脱离限位凹槽A2121，即可将外套筒21A－2A从导向筒21A－2B上拆下来。
外套筒21A－2A和导向筒21A－2B互连后，限位凸环B21的外围的第三限位柱B211位于第一限位柱A11和第二限位柱A12之间，这样，在外套筒21A－2A和导向筒21A－2B相对旋转的过程中，可以通过第一限位柱A11和第二限位柱A12挡止第三限位柱B211，限制外套筒21A－2A和导向筒21A－2B之间的相对旋转的行程。

本申请提供的连接器主件100－1中的滑动件40在第一种方案中用于与光纤适配器配合实现将光纤连接器插头锁持至光纤适配器，而在第二种方案中，滑动件40用于与组装式套件21A的插接件21A－2配合，实现将插接件21A－2锁持至连接器主件100－1，可见本提请提供的连接器主件100－1具有：同样的结构可以匹配不同的套件的优势，其功能及应用均得到了拓展，可以适应不同的应用场景，有利于资源的共用，具有节能降耗的好处。
对第二种方案而言，与组装式套件21A匹配的光纤适配器200－2的具体结构可以参阅图48。图48显示了光纤适配器200－2与组装式套件21A及连接器主件100－1配合的结构特征。沿径向方向，从光纤适配器200－2的中心至外围，光纤适配器200－2设有插芯套筒202’(插芯套筒202’内设插芯收容空间，插芯套筒202’的结构与第一种方案中的光纤适配器200－1中的插芯套筒202结构相同)、插芯套筒202’的外围为中间件收容腔200－21、导向槽200－22及位于外表面的滑槽200－23。滑槽200－23包括开口端200－23A和锁持段200－23B。光纤适配器200－2包括连接导向槽200－22的防呆结构200－221，此防呆结构200－221用于与导向筒21A－2B上的导向槽或导向切口B11配合，保证正确的插入方向，本实施方式中，导向槽200－22为不封闭的包围结构，防呆结构200－221形成在导向槽200－22的首端和末端之间。对于滑槽200－23而言，开口端200－23A处的部分滑槽呈直形槽的形状，且此直形槽的延伸方向为轴向方向，即与光纤适配器的中心轴的延伸方向相同，锁持段200－23B呈弧形延伸，锁持段200－23B延伸轨迹类似部分螺旋线的形状。当将连接器主件200－1与组装式套件21A所构成的光纤连接器插头插入光纤适配器200－2时，通过导向筒21A－2B对准导向槽200－22，导向槽或导向切口B11对准防呆结构200－221，且外套筒21A－2A上的滑块A13对准滑槽200－23的开口端200－23A，即可以将光纤连接器插头插入光纤适配器200－2，插入的过程中，旋转外套筒21A－2A，使得滑块A13滑动至锁持段200－23B远离开口端200－23A的一端，即完成了光纤连接器插头与光纤适配器200－2之间的锁持。锁持状态下，外套筒21A－2A环绕在光纤适配器200－2的外围。具体而言，可以在锁持段200－23B远离开口端200－23A的一端设置定位凹槽，滑块A13滑动至此定位凹槽位置时，可以与此定位凹槽配合实现定位功能。
第三种方案中，组装式套件21B和连接器主件100－1所构成的光纤连接器插头的一种具体的实施方式的详细描述如下。
连接器主件100－1与第一种方案中的与一体式套件匹配的连接器主件100－1为同样的结构。
参阅图49，组装式套件21B的中间件21B－1连接在连接器主件100－1的主壳体22，插接件21B－2连接至中间件21B－1且环绕设置在中间件21B－1的外围。
参阅图50，组装式套件21B中的中间件21B－1与第二种方案中的组装式套件21A中的中间件21A－1可以为相同的结构，与可以为不同的结构。本实施方式中，中间件21B－1设有贯穿内外表面的卡孔21B－1A，卡孔21B－1A的作用是与连接器主件100－1上的主壳体22进行可拆卸连接。中间件21B－1的内表面设有限位结构21B－1B，限位结构21B－1B用于与插芯12配合，实现插芯12的定位。卡孔21B－1A和限位结构21B－1B与第二种方案中的中间件21A－1中的相关特征是相同的，因此它们均是用于与连接器主件100－1配合的部分。本实施方式中，中间件21B－1包括沿轴向分布的第一段21B－11和第二段21B－12，第一段21B－11的外径小于第二段21B－12的外径，第一段21B－11和第二段21B－12之间在外表面处形成台阶面21B－1C，台阶面21B－1C朝向中间件21B－1的前端，第二段21B－12的外表面突出设置卡块21B－1D，此卡块21B－1D朝向中间件21B－1的后端的面为定位面21B－1E，台阶面21B－1C和定位面21B－1E用于与组装式套件21B的插接件21B－2上的相应的限位特征配合，实现轴向上的限位插接件21B－2和中间件21B－1，具体而言，插接件21B－2的前端的内壁与第一段21B－11的外表面接触(如图49所示)，插接件21B－2的内表面设有与台阶面21B－1C配合的限位面(如图54的标号为21B－25的限位面，可以理解为，插接件21B－2的靠近后端的部分的内径大于其前端的内径)。中间件21B－1外表面还突出设置卡持部21B－1F，卡持部21B－1F与卡块21B－1D位于同一侧面，在轴向方向上，卡持部21B－1F位于卡块21B－1D和台阶面21B－1C之间。
第三种方案中的插接件21B－2与第二种方案中的插接件21A－2的区别较大，本方案中，插接件21B－2为一体式架构，不是由外套筒和导向筒构成的组合，而是单独的一个筒状结构，而且插接件21B－2与中间件21B－1滑动连接，插接件21B－2与连接器主件100－1没有连接关系。本方案中的插接件21B－2集成了插接过程中需要用于的防呆、导向、解锁结构，具有结构简单、体积较小的优势。
本方案中，用于与光纤适配器锁持的结构设置在中间件21B－1上，通过插接件21B－2实现解锁。中间件21B－1与插接件21B－2之间的连接关系为轴向方向的滑动连接。
参阅图51，插接件21B－2大致呈方形筒状结构，中间件21B－1亦大致呈方形筒状结构，这样插接件21B－2套设在中间件21B－1的外围，插接件21B－2和中间件21B－1之间通过接触配合就可以实现周向定位，即能够防止它们之间的相对旋转。
参阅图51，插接件21B－2一侧的外表面设有突出的防呆结构21B－21，此防呆结构21B－21用于与光纤适配器上的对应的防呆槽配合，以保证插接件21B－2与光纤适配器插接的方向。具体而言，防呆结构21B－21呈条状延伸，且延伸方向为轴向方向，防呆结构21B－21的前端为圆弧状端面，圆弧状端面也可以用斜面代替，其作用为插接过程的导向，使得插接更顺利。
插接件21B－2的另一个侧面上设有挖空区21B－22(挖空区21B－22的数量为两个，对称分布在相对的两个侧面上)，中间件21B－1组装至插接件21B－2时，卡持部21B－1F和卡块21B－1D位于此挖空区21B－22中。挖空区21B－22包括相连通的第一孔21B－221和第二孔 21B－222，第二孔21B－222面积大于第一孔21B－221，第一孔21B－221位于第二孔21B－222的一端形成T状孔结构。第一孔21B－221用于收容卡块21B－1D，第一孔21B－221的孔壁包括限位面21B－224，限位面21B－224朝向第二孔21B－222，限位面21B－224用于与卡块21B－1D配合，形成插接件21B－2的轴向限位，在轴向方向上，通过此限位面21B－224和连接器主件200－1的主壳体22的前端面实现对插接件21B－2的限位。第二孔21B－222对应卡持部21B－1F设置，第二孔21B－222用于收容光纤适配器上的设有卡勾的弹性臂，以使卡勾能够与卡持部21B－1F配合实现锁持状态。
插接件21B－2外表面还凹设一对滑槽21B－23，这对滑槽21B－23对称分布在第二孔21B－222的两侧，且延伸方向为轴向方向，各滑槽21B－23均包括相连的第一区域21B－231和第二区域21B－232，沿轴向方向，第二区域21B－232位于第一区域21B－231和第一孔21B－221之间，第二区域21B－232的槽底包括第一平面，第一平面与插接件21B－2内表面之间的距离小于外表面与插接件21B－2内表面之间的距离。第二区域21B－232的槽底为连接在外表面和第一平面之间的斜面。滑槽21B－23用于光纤适配器和插接件21B－2之间的解锁。
本方案中提供的实施方式中，中间件21B－1与连接器主件100－1的主壳体22之间为可拆卸式连接结构，插接件21B－2与中间件21B－1可拆卸连接，光纤连接器插头组件与光纤适配器200－3插接的过程，通过插接件21B－2与光纤适配器200－3配合实现导向，通过中间件21B－1与光纤适配器200－3配合实现锁持固定。
参阅图52，光纤适配器200－3的结构如下：沿径向方向，从光纤适配器200－3包括插芯套筒202A和环绕在插芯套筒202A外围的主体套筒201A，主体套筒201A和插芯套筒202A之间的空间为用于收容组装式套件21B的收容空间200－31，收容空间200－31的一端为用供光纤连接器插头插入的插口，收容空间200－31中与插口相对的底部为主体套筒201A的底端，主体套筒201A设有贯穿内外表面的防呆槽200－32，防呆槽200－32在主体套筒201A的端面上形成开口，以供防呆结构21B－21从此开口处插入防呆槽200－32。主体套筒201A和插芯套筒202A之间设有一对弹性臂200－33，弹性臂200－33的一端固定连接至主体套筒201A的底端，弹性臂200－33上远离主体套筒201A的一端设有卡勾200－34和滑块200－35，卡勾200－34和滑块200－35均位于弹性臂200－33的朝向插芯套筒202A的一侧，滑块200－35的数量为两个且分布在卡勾200－34的两侧，滑块200－35用于与插接件21B－2上的滑槽配合，卡勾200－34用于与中间件上的卡持部21B－1F配合，实现锁持状态。弹性臂200－33与插芯套筒202A之间形成用于容纳组装式套件21B的空间，弹性臂200－33与主体套筒201A之间形成空隙，此空隙用于提供弹性臂200－33在外力(插拔光纤连接器插头的力)的作用下的弹性摆动空间。
参阅图53和图54，插接件21B－2插入光纤适配器200－3且处于锁持状态时，限位面21B－224用于与中间件21B－1的定位面21B－1E配合(图未示出此结构关系)，且光纤适配器200－3内的卡勾200－34与中间件21B－1上的卡持部21B－1F配合。需要将光纤连接器插头从光纤适配器上取下时，与沿轴向向远离光纤适配器的方向拉动插接件21B－2，能够使得插接件21B－2移动，移动的过程中，滑块200－35在滑槽21B－23上移动(结合参阅图49和图52)，通过滑槽21B－23的斜面状的第二区域21B－232迫使滑块200－35产生径向位移，同时带动弹性臂200－33产生弹性摆动，使得卡勾200－35脱离卡持部21B－1F，从而实现解锁，第一限位面21B－223用于与中间件21B－1的台阶面21B－1C配合以在解锁的过程中实现插接件21B－2滑动过程的限位。
第四种方案中，组装式套件21C和连接器主件100－1所构成的光纤连接器插头的一种具体的实施方式的详细描述如下。
本方案中，连接器主件100－1与前面三种方案的连接器主件结构可以相同，但是本方案不需要连接器主件100－1上的滑动件，因此，连接器主件100－1应用在本方案中时，可以将滑动件拆掉，但其它部分结构是不变的。
参阅图55和图56，组装式套件21C的中间件21C－1连接在连接器主件100－12，插接件21C－2连接至中间件21C－1且环绕设置在部分中间件21C－1的外围。本方案中的组装式套件21C的中间件21C－1与第二种方案和第三种方案的中间件的结构可以是相同的，也可以是不同的。
参阅图57，一种实施方式中，中间件21C－1的具体结构为：中间件21C－1呈套筒状包括筒主体21C－10，筒主体21C－10的前端突设一对导向臂21C－11，导向臂21C－11从筒主体21C－10的前端面沿轴向向前延伸，这对导向臂21C－1用于与光纤适配器配合实现导向，例如光纤适配器上设一对导向槽，导向臂21C－11与导向槽配合实现导向功能。筒主体上靠近其后端的位置形成一对弹性臂21C－12，通过在筒主体21C－10上设置切槽的方式形成弹性臂21C－12，弹性臂21C－12的延伸方向为轴向方向，弹性臂21C－12的末端设有一对卡扣部21C－13，此卡扣部21C－13用于将中间件21C－1卡持至连接器主件100－1的主壳体上。
本实施方式中，中间件21C－1的外表面还突出设置限位环21C－14，此限位环21C－14用于限位插接件21C－2，使得组装后的插接件21C－2无法从中间件21C－1前端的方向取下来。限位环21C－14的前端设有用于收容密封件的凹槽21C－15，凹槽21C－15中的密封件用于实现中间件21C－1和光纤适配器之间的密封连接。所述中间件21C－1与所述连接器主件100－1之间易设密封结构。
参阅图56，所述插接件21C－2为一体式的筒状结构，所述插接件21C－2固定连接至所述连接器主件100－1，所述插接件21C－2包围部分所述中间件21C－1，其余的部分所述中间件21C－1位于所述插接件21C－2的外部，所述插接件21C－2包括用于与所述光纤适配器连接的外螺纹21C－21。一种实施方式中，插接件21C－2固定在中间件21C－1和连接器主件100－1的主壳体22之间。组装过程中，先将插接件21C－2套设在主壳体22上，主壳体22的外表面有相应的结构支撑限位插接件21C－2，再将中间件21C－2插入插接件21C－2和主壳体之间，通过中间件21C－2上的弹性臂21C－12及卡扣部21C－13与主壳体上的卡持结构配合，将中间件21C－1固定连接至主壳体。图56可以看到，组装后插入接件21C－2和中间件21C－1的弹性臂21C－12之间有间隙，此间隙的存在是为弹性臂21C－12提供锁持及解锁过程中的避让空间，在外力作用下拉拔中间件21C－1，弹性臂21C－12会被迫张开，即向此间隙内偏移，使得卡扣部21C－13处于解锁状态。
图58所示为连接器主件100－1与组装式套件21C配合后安装至光纤适配器200－4的状态，中间件21C－1的导向臂21C－11与光纤适配器200－4的导向槽200－41配合。插接件21C－2的外螺纹21C－21与光纤适配器200－4的内螺纹配合实现光纤连接器插头组件与光纤适配器的锁持状态。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
