Description

一种SC型预端接连接器 技术领域
本发明涉及光纤连接器技术领域，尤其涉及一种SC型预端接连接器。
背景技术
在光纤入户过程中，受常规光纤连接器外形尺寸的限制，通常采用光缆布线后加装现场连接器、或者热熔的方法实现光路连接。而这两种连接方式都存在成本较高的问题，且现场连接器由于在使用时，对插芯端面的研磨精度有限，因而其还存在质量可靠性不高，对操作人员技能水平要求较高的问题。
因此，为解决上述问题，将工厂进行加工研磨等工艺制作的光纤连接器用作现场光路连接。如图1所示为这种光纤连接器的结构示意图，其包括内框套3，内框套3的左侧连接有伸入内框套3的内部的插芯1，内框套3的右侧连接有伸入内框套3的内部的止动环2’，其中，内框套3与止动环2’之间设置有弹簧5，在内框套3与止动环2’的外侧套设外框套4，并在止动环2’的端部连接有尾护套7’，在插芯1的端部套有防尘帽6’。在此结构中，弹簧5的限位是通过内框套3和止动环2’共同实现的，这种结构比较复杂，对安装技术要求高且可靠性不易保证；同时，插芯1的端面在工厂进行加工后采用防尘帽6’保护，但是由于防尘帽常常为了很好地与插芯1配合，其加工精度要求较高，导致成本增加，且在运输过程中，由于其硬质特性，经碰撞或摩擦常常容易掉落，进而起不到保护插芯端部的作用。

具体实施方式
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
需要说明的是：在本实施例中，连接器是接在光缆的端部的，并且光缆穿入连接器后使得光缆中的光纤插入插芯中用于接续，因此，按照光纤穿入后其前端所处的位置为整个装置的前端。
如图2至8所示，一种SC型预端接连接器，包括插芯1、以及与插芯1连接的尾柄2，尾柄2上套设有弹簧5，光纤8依次穿入尾柄2、插芯1后与插芯1、尾柄2、弹簧5共同组成插芯组件；
还包括内框套3，内框套3的内部沿轴向开设有用于放置插芯组件的容置孔31，内框套3的一侧部开设有与容置孔31相平行且连通的安装槽32，现场施工时，插芯组件从安装槽32挤入容置孔31中。
其在工厂进行插芯、尾柄、弹簧以及光纤的组装加工工序，在组装后，还可以在工厂对插芯端面进行研磨处理，进而提高光纤连接精度，同时，将组装好的插芯组件作为一个整体与内框套进行装配，并利用安装槽挤入容置孔中，使得操作更见简便，并且位置可控，装配精度高，装配难度低，无需在现场使用其他工具即可完成装配，降低工人的操作难度与强度，降低成本。
其中，尾柄2包括相连接并呈台阶状的插芯连接段21与弹簧固定段22，插芯连接段21的内部开设有插芯连接孔，弹簧固定段22的内部开设有光缆穿过孔，插芯1的内部开设有光纤过孔，插芯1伸入插芯连接孔后紧配合连接，光纤过孔、光缆穿过孔相连通并同轴设置，光纤8依次穿过光缆过孔、 光纤过孔设置。其中，弹簧5套设于弹簧固定段22上，且弹簧5的一端与插芯连接段21和弹簧固定段22之间的台阶面相抵；内框套3的一侧开设有沿径向的让位槽33，弹簧5的另一端与让位槽33的第二配合面34相抵。
插芯1与尾柄2的连接是通过插芯连接孔与插芯1紧配合实现的，其连接紧凑，结构简单，无需增加额外的固定部件即可实现，操作更加方便。
其中，内框套3的一侧还开设有沿径向的凹槽，凹槽的第三配合面35与插芯连接段21的第一配合面23相抵。利用相互配合的面的相抵作用，使得插芯组件稳定地固定在内框套3中。
优选的，插芯组件的外侧套设有用于保护插芯组件并能牵引插芯组件穿管的热缩管7。
优选的，该SC型预端接连接器在工厂加工完成后，其插芯1的端部套设有热缩防尘帽6。
此时，该SC型预端接连接器的现场施工装配方法，如下：
移除热缩管7；
将插芯组件装入内框套3中；
将外框套4套装于内框套3的外侧；
移除热缩防尘帽6。
在工厂进行插芯、尾柄、弹簧以及光纤的组装加工工序，在组装后，还可以在工厂对插芯端面进行研磨处理，以便于后期连接继续时提高光传输率，在工厂装配后，在插芯的端部套设热缩防尘帽，利用热缩防尘帽6的热缩特性，使得热缩防尘帽能与插芯紧密配合，不会在工厂到现场的过程中掉落，进而能够很好地保护插芯端面与光纤端面；又在插芯组件的外侧套设热缩管7，利用热缩管7的热缩特性，使其紧密包裹插芯组件，避免其散落， 又能很好地保护各个部分避免受损；而在现场进行组装时，有些场所因为布线的需要，需要将连接器从现场的管件的一端穿过管件后在管件的另一端进行接续，而现有的连接器一般在组装后尺寸较大，穿管困难，因此，该SC型预端接连接器由于在现场时，插芯组件与其他部件如内框套、外框套等未进行装配，因而可以直接利用热缩管7带动插芯组件单独进行穿管，因而对待穿过的管件的尺寸要求不高，能够适应大部分规格的管件，适应性更强，在穿过管件后，在管件的另一端进行组装时，移除热缩管7，如剪切侧面使其掉落，使得插芯组件外露，再将插芯组件装入内框套3即可，此时，装配后的尺寸将不会影响布线，待接续工作准备好后，再将热缩防尘帽6移除，进行光纤端面接续工作，整个过程连续，且互不影响，能够实新较好的保护，成本低、可靠性高，能有效保护插芯的端面，且安装方便，适用于现场操作，降低对安装人员的要求。
优选的，热缩管7的前端设置有用于牵引插芯组件穿管的牵引钩71。在具体穿管时，一般待穿过的管件内会预留有线，将线系在牵引钩71上后，在管件的另一端拉动线，使得插芯组件在线的拉动下跟随热缩管7穿至管件的另一端，实现穿管，其操作简便，利用现场现有的线实现穿管，无需额外准备其他辅助设施，成本低，适应现场作业。该牵引钩71与热缩管7可以为注塑一体成型，由于热缩管7的热缩特性，在包裹插芯组件的同时，也能很好地与牵引钩71连接，可靠性高。
该SC型预端接连接器还包括外框套4，现场施工时，外框套4套设在内框套3上。整个结构相对于现有技术中的光纤连接器而言，减少尾护套和止动环两个零件，使得整体结构简化，组装更加便利。该预端装连接器所适用的光缆为0.9mm、2.0mm、3.0mm。装配后，整体结构的最大外形尺寸为 8.4mm×9.4mm×30mm，与常规SC连接器完全兼容。
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它具体实施方式，这些方式都将落入本发明的保护范围之内。
