具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
在本发明的描述中，术语“内”、“外”、“纵向”、“横向”、“上”、“下”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明而不是要求本发明必须以特定的方位构造和操作，因此不应当理解为对本发明的限制。
此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
实施例1:
为了解决前述问题，本发明实施例1提出了一种整体式SC连接器；
如图1和图2所示，该整体式SC连接器包括：一体光口座1、中间件2、陶瓷套筒3和扣板12，其中：
所述中间件2包括限位座21和插座22，所述插座22设置于所述限位座21上；在可选的实施例中，所述插座22设置在所述限位座21的中间区域，所述插座22垂直于所述限位座21所在的平面。
所述插座22用于供SC跳线插入。
所述限位座21用于与另一个所述中间件2的限位座21相贴合，以对两个所述中间件2进行拼接，并保证两个所述中间件2的插座22相对接，实现两个所述中间件2的组装；其中，两个中间件2的限位座21贴合后，两个插座22的开口相互重合，也可以理解为，两个插座22的轴线在同一直线上。
如图9所示，所述一体光口座1内部设置有装配槽11，其中，所述装配槽11设置在所述一体光口座1的中间位置；
所述装配槽11用于容置拼接后的两个限位座21，将完成组装的两个所述中间件2固定在所述一体光口座1内部；可以理解为装配槽11的宽度略大于限位座21的宽度的两倍。
所述陶瓷套筒3设置于拼接后的两个所述中间件2的插座22内部，用于在两个对接的所述插座22中传递来自SC跳线的光信号。
本实施例中，一个整体式SC连接器中包括两个中间件2，一个中间件2对应一个SC跳线；限位座21呈长方体状，所述插座22呈圆柱体状，插座22垂直设置于限位座21上；插座22中的圆柱腔体与SC跳线尺寸适配，供SC跳线插入用；当两个中间件2插入对应的SC跳线后，SC跳线的光纤端面在陶瓷套筒3中对接。
两个中间件2组装后设置在一个一体光口座1中，通过一体光口座1将组合后的中间件2进行固定，SC跳线插入插座22后通过中间件2上的固定卡扣25固定，实现两个SC跳线的固定对接。
现有SC连接器，是通过两个分离式的光口座分别套接于两个中间件上，两个中间件中设置有陶瓷套筒，并通过超声波熔接将两个光口座熔接在一起， 因此需要对应配备超声波熔接设备，成本较高，并且在熔接的过程中，两个对接的光口座不容易对齐，可能会导致陶瓷套筒的破损，使得现有的SC连接器容易存在断裂风险；
在本实施例中，预先将两个中间件2组装在一起，形成一个组件，然后通过装配槽11将该组件固定在一体光口座1，本实施例提供一体光口座1来容纳固定拼接好的中间件2，SC跳线通过一体光口座1的两端面插入对应的中间件2即可完成对接，一体光口座1避免了由于常规光口座对接不齐而导致的陶瓷套筒破损的现象，同时也无需使用超声波熔接工艺。
下面具体说明中间件2的结构，以及两个中间件2如何对齐，如图2和图3所示，所述限位座21的两侧边缘分别设置有第一凸台23与第二凸台24，其中，所述第一凸台23设置于所述限位座21一侧的中间位置；所述第二凸台24设置于所述限位座21另一侧的两端位置；具体地，所述限位座21的一侧设置有一个第一凸台23，该第一凸台23设置在相应侧边的中间位置；所述限位座21的另一侧设置有两个第二凸台24，两个第二凸台24分别设置在相应侧边的两端位置，其中，两个第二凸台24之间的间隔大小与所述第一凸台23的尺寸相匹配。
在实际使用中，当其中一个中间件2的限位座21与另一个中间件2的限位座21相贴合时，其中一个中间件2的第一凸台23用于插入另一个中间件2的两个第二凸台24之间，并与另一个所述中间件2的两个第二凸台24内侧相抵接，实现两个所述限位座21的拼接。
如图2所示，在本实施例中，第一凸台23的顶面相对于所述限位座21的高度为H1，第二凸台24的顶面相对于所述限位座21的高度为H2，其中，H1与H2相等，且H1(H2)与限位座21的厚度D相等。按照前述尺寸设置第一凸台23和第二凸台24可以保证两个中间件的限位座21能够紧密的贴合在一起，尽量避免缝隙。
在本实施例中，第一凸台23和第二凸台24不仅具有卡合固定的作用， 还具有定位的作用，可以引导两个限位座对齐，对位方式简单，不易发生错位。而且，采用结构件配合的方式将两个中间件拼接在一起，不需要采用超声波熔接，可以降低工艺的复杂度，也不会出现超声波熔接处断裂的风险，提高可靠性。
在本实施例中，所述第一凸台23与第二凸台24均为长方体状，并突出于所述限位座21的表面与侧面进行设置；限位座21的两个所述第二凸台24之间的空间，能够正好容纳第一凸台23，当两个中间件2进行对接时，其中一个中间件2的第一凸台23对应插入另一个中间件2的两个第二凸台24之间，其中一个中间件2的两个第二凸台24之间对应容纳另一个中间件2的第一凸台23；第一凸台23的两侧面与第二凸台24的侧面相抵接，保证中间件2之间在上下方向上的固定；第一凸台23的内侧面与限位座21的侧面相抵接，保证了中间件2之间在左右向上的固定，进而保证在两个中间件2的限位座21表面相贴合的状态下，两个中间件2之间的相对固定。
其中，相互拼接的限位座21呈长方体状。
如图4所示，所述一体光口座1底部设置有开槽13，所述组装后的中间件2需要通过底部的所述开槽13进入一体光口座1中完成固定安装，安装完毕后的中间件2底部需要支撑件，在优选的实施例中，一体光口座1下端还需要对应安装扣板12。
继续参阅图4-8，所述整体式SC连接器还包括扣板12，其中：
所述扣板12用于与所述一体光口座1底部的开槽13相配合，从而为所述一体光口座1内部的中间件2提供底部支撑；
所述扣板12两侧设置有第三限位台1231，所述开槽13两侧对应设置有槽口17；
所述第三限位台1231从上至下长度逐渐增大，并且所述第三限位台1231一侧面为倾斜面，所述槽口17一侧设置有第五限位台171；当所述扣板12与所述一体光口座1底部的开槽13相配合时，所述第三限位台1231 沿着所述倾斜面滑入所述开槽13中，并将所述第三限位台1231的下端与所述第五限位台171上端相抵接，完成所述扣板12与所述一体光口座1之间的相对固定；
所述开槽13用于供组合后的中间件2穿过，实现中间件2与一体光口座1之间的拆卸与安装。
所述扣板12包括两个相对设置的第一侧边122和两个相对设置的第二侧边123，第一侧边122上设置有第一限位台1221，其中，第一限位台1221呈阶梯状，具体地，所述扣板12包括本体，所述第一侧边122的表面与所述本体的表面不在同一个平面，二者存在高度差，以形成阶梯状的第一限位台1221。
如图5-图8所示，所述扣板12上的第一侧边122上设置有阶梯状的第一限位台1221，所述第一限位台1221与所述一体光口座1底面上的阶梯状的第二限位台16相配合，实现所述第一限位台1221与所述第二限位台16在第一方向上的抵接，保证将所述扣板12在第一方向上同所述一体光口座1的固定。
由于考虑到扣板12是从所一体光口座1下端朝上安装到开槽13中，因此所述第一限位台1221的阶梯由上至下长度依次增加，所述第二限位台16与所述第一限位台1221相适配，所述第一限位台1221的侧面与所述第二限位台16的侧面在第一方向上相抵接。
所述扣板12上的第二侧边123上设置有至少两个第三限位台1231，所述第三限位台1231与所述一体光口座1底面侧边上的槽口17相配合，所述第三限位台1231于所述第二侧边123上突出设置，其中所述第三限位台1231的两侧边同所述槽口17内侧边在第一方向上相抵接，实现所述扣板12在第一方向上同所述一体光口座1的固定，所述第二侧边123上除开所述第三限位台1231的部分同所述开槽13的内侧相抵接，保证所述扣板12在第二方向上同所述一体光口座1的固定。
由于考虑到扣板12是从所一体光口座1下端朝上安装到开槽13中，所述第三限位台1231从上至下长度逐渐增大，从而保证所述第三限位台1231的侧面与第三限位台1231的底面呈倾斜角，所述槽口17下端一侧设置有第五限位台171，当所述扣板12朝上安装到开槽13的过程中，第三限位台1231的长度较小的一头先进入所述槽口17中，通过第三限位台1231侧面的倾斜，将所述第三限位台1231划入所述槽口17中，同时所述第三限位台1231的底端与所述第五限位台171上表面相抵接，防止所述扣板12从一体光口座1底部脱离。
其中，所述第一方向为垂直于所述第一侧边122的方向，所述第二方向为垂直于所述第二侧边123的方向。
所述扣板12上表面还设置有与中间件2外部轮廓相匹配的凹槽，用于为设置于一体光口座1中的中间件2提供容纳空间并对其进行限位固定。
如图9和图10所示，所述一体光口座1内部中间位置设置有装配槽11，具体包括：
所述装配槽11设置于所述一体光口座1内部上表面与内部两侧面的中间位置，并且在所述一体光口座1内部两侧面的底端留有开口111；
所述开口111用于供拼接后的限位座21插入从而进入所述装配槽11中，直至拼接后的限位座21上表面同一体光口座1内部上表面的装配槽11相抵接，完成所述装配槽11与所述组装后的中间件2之间的配合固定。
所述一体光口座1内部上表面与内部两侧面上设置的装配槽11为连接一体，所述装配槽11的宽度大于等于拼接后的限位座21的宽度，所述装配槽11的侧面将拼接后的限位座21在第一方向上相抵接，所述装配槽11的底面将拼接后的限位座21在第二方向上相抵接，从而将组合后的中间件2在一体光口座1中固定。
考虑到中间件2对扣板12向下的压力，单纯通过第三限位台1231与槽口17的抵接，无法稳定的为中间件2提供支撑，因此还需要设置固定件4 来对扣板12进行进一步加固。
如图11和图12所示，所述整体式SC连接器还包括固定件4；
所述固定件4包括底板41和夹板42，所述夹板42设置于所述底板41的两端，所述夹板42上设置有开孔421；
所述底板41容置在所述扣板12的第一凹槽121内，将所述固定件4设置在所述扣板12上；
所述夹板42容置在所述一体光口座1两侧面的第二凹槽14内，其中，第二凹槽14表面设置有第四限位台15，所述第四限位台15卡入所述开孔421内，从而将固定件4固定在所述一体光口座1上。
在本实施例中，固定件4的底板41抵接第一凹槽121的底壁，夹板42夹设在一体光口座1的两侧面，将扣板和一体光口座1固定在一起。
进一步地，所述固定件4还包括引脚43；所述引脚43设置于所述底板41上；其中，所述引脚43背离所述夹板42设置。每个所述夹板42的中间位置对应设置一个引脚43。
所述引脚43用于与PCB(PCB＝Printed Circuit Board)板相对接，实现所述整体式SC连接器在PCB板上的定位固定。
在可选的实施例中，所述固定件4为钣金件，所述固定件4可以一体成型设置。
在本实施例中，所述第一凹槽121深度大于等于所述底板41的厚度，所述第一凹槽121的宽度大于等于所述底板41的宽度，保证所述固定件4设置于所述扣板12上时，所述底板41的侧面同第一凹槽121两侧面相抵接，保证所述底板41同扣板12在第一方向上的固定；所述第二凹槽14轮廓的形状尺寸同所述夹板42一致，所述第二凹槽14的深度大于等于所述夹板42的厚度，保证所述固定件4设置于所述一体光口座1上时，所述夹板42的侧面同所述第二凹槽14的侧面相抵接；所述开孔421形状尺寸与所述第四限位台15相配合，所述第四限位台15下端同第二凹槽14底面相接，同时 第四限位台15下端至上厚度逐渐增大(其中，下端指的是靠近扣板的一端)，保证在安装固定件4时，所述夹板42能够从第四限位台15下端滑动向上推进，从而将所述第四限位台15滑进所述开孔421中，实现固定件4同一体光口座1的相对固定。
结合图13-图15，所述中间件2的还包括至少两个固定卡扣25(如图2所示)，所述固定卡扣25设置于所述限位座21上并设置于所述插座22的外侧；所述固定卡扣25顶端设置有卡勾251；
所述固定卡扣25用于在SC跳线插入所述插座22时，将所述卡勾251与SC跳线外围的限位台相抵接，从而将SC跳线固定。
当所述中间件2固定于所述一体光口座1中时，所述中间件2两侧与所述一体光口座1内壁之间预留有预设空间；
所述预设空间用于在SC跳线插入所述插座22时，为被SC跳线挤开的固定卡扣25提供避让空间。
在本实施例中所述限位座21上设置有两个固定卡扣25，所述卡勾251设置于固定卡扣25的顶端，所述卡勾251通过连接杆同限位座21相连，构成固定卡扣25，所述卡勾251呈三角状，所述卡勾251位于所述固定卡扣25的顶端内侧，所述卡勾251底面同所述固定卡扣25的连接杆之间角度为锐角，所述锐角部分即为负角，当所述SC跳线插入所述插座22的过程中，所述SC跳线两侧顺着所述卡勾251的斜面滑入所述卡勾251的底面，所述卡勾251底面部分与所述SC跳线外围限位台相抵接，所述负角通过自身的角度保证SC跳线外围不易从卡勾251中脱出，所述预设空间由本领域技术人员根据实际情况自行进行设定，所有适用的预设空间设定均应在本实施例的保护范围内。
进一步地，所述插座22内部设置有圆柱形腔体221，其中，所述圆柱形腔体221用于在两个所述中间件2组装时，容纳所述陶瓷套筒3；所述圆柱形腔体221在靠近端口的位置设置有止挡位2211，所述止挡位2211的口径 小于所述陶瓷套筒3的截面直径。
当所述陶瓷套筒3设置于所述圆柱形腔体221中时，所述止挡位2211用于与所述陶瓷套筒3相抵接，防止所述陶瓷套筒3从所述圆柱形腔体221中滑出。
在本实施例中，要保证所述陶瓷套筒3能固定于两个中间件2的圆柱形腔体221中且不滑动，需要保证两个圆柱形腔体221的长度加上两个限位座21的厚度之和略大于陶瓷套筒3的长度，并且所述止挡位2211在圆柱形腔体221中的位置需要保证陶瓷套筒3能与两端的止挡位2211相抵接，因此在设计中间件2时，需要根据实际使用的陶瓷套筒3的长度，来设计中间件2的圆柱形腔体221的长度、限位座21的厚度以及止挡位2211的位置。
实施例2:
本发明实施例在实施例1的一种整体式SC连接器的基础上，提供一种整体式SC连接器的使用方法。
本实施例的整体式SC连接器的使用方法包括：整体式SC连接器的安装组合使用方法和整体式SC连接器的实际应用方法。
所述整体式SC连接器的安装组合使用方法包括：
两个所述中间件2通过所述限位座21之间的拼接完成组装；
将陶瓷套筒3放入中间件2的圆柱形腔体221中，并将两个中间件2进行对接，其中一个中间件2的第一凸台23对应插入另一个中间件2的两个第二凸台24之间，中间件2的两个第二凸台24之间对应容纳另一个中间件2的第一凸台23；第一凸台23的两侧面与第二凸台24的侧面相抵接，保证中间件2之间在上下方向上的固定；第一凸台23的内侧面与限位座21的侧面相抵接，保证了中间件2之间在左右向上的固定，进而保证在两个中间件2的限位座21表面相贴合的状态下，两个中间件2之间的相对固定；
所述一体光口座1的装配槽11与所述拼接后的限位座21相配合，将完成组装的两个所述中间件2固定在所述一体光口座1内部；
所述组装后的中间件2从所述一体光口座1底部的开槽13进入，相互拼接的所述限位座21通过所述开口111插入所述装配槽11中，完成所述装配槽11与所述拼接后的限位座21之间的配合固定；
所述扣板12与所述一体光口座1底部的开槽13相配合，从而为所述一体光口座1内部的中间件2提供支撑；
所述底板41与所述扣板12下表面的第一凹槽121相配合，实现所述固定件4在所述扣板12上的固定；
所述夹板42与所述一体光口座1两侧的第二凹槽14相配合，所述开孔421用于与所述第二凹槽14上设置的第四限位台15相配合，实现所述固定件4与所述一体光口座1之间的相对固定；
所述引脚43与PCB板相对接，实现所述整体式SC连接器在PCB板上的定位固定。
所述整体式SC连接器的实际应用方法包括：
将两根不同的SC跳线对应插入所述整体式SC连接器两端的插座22中；
所述SC跳线两侧顺着所述卡勾251的斜面划入所述卡勾251的底面，所述卡勾251底面部分与所述SC跳线外围限位台相抵接，所述负角通过自身的角度保证SC跳线外围不易从卡勾251中脱出；
一端SC跳线的光信号通过所述陶瓷套筒3传递给另一端的SC跳线。
实施例3:
本发明实施例3考虑到整体式SC连接器可由金属制成或者塑料制成，而在塑料制成且在高温场景的使用情景下，所述固定卡扣25在SC跳线插入插座时被撑开，在固定卡扣25被多次撑开后，所述固定卡扣25可能会因为高温产生永久形变，对应两个固定卡扣25之间的距离会永久增大，导致固定卡扣25无法对SC跳线进行有效稳定的固定，因此本实施例在与固定卡扣25位置对应的扣板12上表面和一体光口座1内部上表面设置抵接斜台252， 并将固定卡扣25前端的卡勾251的上下表面设置为与抵接斜台252相适配的斜面，从而保证当固定卡扣25被SC跳线撑开时，所述卡勾251的上下表面同抵接斜台252相抵接，避免固定卡扣25之间被频繁撑开至过大，导致发生永久形变。
如图16和图17所示，所述抵接斜台252设置于扣板12上表面和一体光口座1内部上表面，对应将卡勾251的上下表面进行抵接，使卡勾251受到向上和向下的抵接力，并且由于卡勾251上下表面为与抵接斜台252相匹配的斜面，因此当固定卡扣25被SC跳线撑开时，卡勾251的上下端会受到来自抵接斜台252向内的抵接力，由于塑料制品本身具有一定的弹性恢复力，因此卡勾251中间部分会被向外撑开后再回复成原来的状态，而卡勾251的上下端位置则几乎不会发生改变，避免了整个固定卡扣25发生较大程度的形变，进而避免了在高温作用下可能会发生的较大程度的永久形变。
其中，所述抵接斜台252的上表面的斜台的倾斜角度由本领域人员在不干扰SC跳线使用的前提下自行设定，所有满足条件的倾斜角度设定均应在本实施例的保护范围内，所述卡勾251上下端的倾斜角度与抵接斜台252的上表面的斜台的倾斜角度相同；处于同一插座侧的抵接斜台252之间的距离设定，应保证抵接斜台252不会同处于插拔状态的SC跳线产生碰撞。
实施例1中的整体式SC连接器的组合中间件2在固定于一体光口座1中时，仅通过中间件2中间的限位座21与装配槽11之间的抵接进行固定支撑，但所述固定卡扣25在一体光口座1中为悬空状态，导致组合中间件2在一体光口座1中的固定并不足够稳定；而本实施例的抵接斜台252能进一步将固定卡扣25进行支撑抵接，进一步增强了组合中间件2在一体光口座1中固定的稳定性。
如图18所示，相对于图17中的方案，本实施例还提供一种的方案抵接斜台252高度相对更小，固定卡扣25的卡勾部分251宽度相对更大的方案，避免由于抵接斜台252高度过高，从而在长期与卡勾部分251抵接的过程中， 稳定度不足而发生断裂的现象，高度更低抵接斜台252保证了抵接斜台252自身的稳定性，与之相对的，需要将固定卡扣25的卡勾部分251宽度增大，以保证卡勾部分251能与抵接斜台252相抵接。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
