Description

一种光纤连接头和光纤连接组件 技术领域
本发明涉及计算机通信领域，具体涉及一种光纤连接头和光纤连接组件。
背景技术
在光纤到户(Fiber To The Home，FTTH)网络的入户段线缆布放过程中，通常采用熔接技术，即在分纤盒内分配好对应每户的光纤端头，将每户的光纤端头和入户光缆用光纤熔接机在分纤盒内进行熔接，再将入户光缆铺设到每家每户，在入户光缆的另一端，也需要进行一次现场熔接，以便和每家每户的用户终端盒连接起来，使用上述熔接技术需要专用的光纤熔接设备，对操作人员的技术要求较高，且操作起来过程繁琐、不便利。
光纤插芯通常设置在光纤连接头上，目前光纤连接头上的光纤插芯通常是裸露在外的，光纤连接头在与光纤连接座对接前，光纤插芯可能会与外界接触而受损，从而影响到光纤的性能。
发明内容
针对现有技术中存在的缺陷，本发明的目的在于提供一种光纤连接头、光纤连接座和光纤连接组件，可以防止光纤插芯在光纤连接头在与光纤连接座对接前受损。
为达到以上目的，本发明提供一种光纤连接头，其包括：
主体部；
位于所述主体部一端的插入部，所述插入部远离所述主体部的一 端设有光纤插芯；
所述插入部末端还设有围绕所述光纤插芯的筒状结构，所述筒状结构与所述光纤插芯间隔设置；以及
套设在所述筒状结构上的连接头套筒，其可沿所述筒状结构滑动，当所述连接头套筒滑动至远离所述主体部末端时，所述连接头套筒至少部分位于所述光纤插芯外。
由于在筒状结构上还套设有连接头套筒，且其至少部分位于光纤插芯外，这样连接头套筒即可起到保护光纤插芯的作用，能够防止光纤插芯在光纤连接头在与光纤连接座对接前受损，从而能够保证光纤连接的性能。
同时，由于连接头套筒可以回缩，因此，与光纤连接头适配的光纤连接座无需额外设置承接连接头套筒的空间，而设置承接连接头套筒的空间需要使增加光纤连接座的直径以提供位置来设置这一空间，从而可以有效的降低光纤连接座的直径，从而提高光纤连接座在面板上的密度。并且，由于连接头套筒可以回缩，使得光纤连接头连接到光纤连接座后整体的长度变短。
在上述技术方案的基础上，所述筒状结构与所述光纤插芯之间形成一插入空间。
在上述技术方案的基础上，所述插入空间为环形。
环形的插入空间在插入时更方便匹配。
在上述技术方案的基础上，所述光纤连接头还包括连接头对接部，所述连接头对接部围设在所述插入部外侧，并从所述插入部的始端延伸至所述筒状结构处，所述连接头对接部与所述插入部间隔设置，且所述连接头对接部靠近所述筒状结构一端设有内螺纹。

设置弹簧后，在光纤连接头与光纤连接座对接后，弹簧将会受到压缩，当需要将光纤连接头与光纤连接座分离时，弹簧能够提供驱动力，更有利于光纤连接头与光纤连接座的分离。
在上述技术方案的基础上，
所述插入部与所述主体部一体成型；或者，
所述插入部组设于所述主体部。
为了使光纤连接头整体性更强，插入部与主体部可以是一体成型，当然，为了生产方便，也可将插入部组设于主体部。
在上述技术方案的基础上，所述插入部和所述主体部均为圆柱状，且所述插入部直径小于所述主体部直径。
由于插入部和主体部均为圆柱状，从而能够与光纤连接座更好的配合，且方便对接。由于插入部直径小，从而可以有效的降低整体的 直径，有效提高光纤连接组件的布置密度。
在上述技术方案的基础上，所述筒状结构用于插入与光纤连接头适配的光纤连接座的插槽。
在上述技术方案的基础上，所述插入部的始端还设有密封件。
设置密封件后，可以防止在光纤连接头与光纤连接座对接时漏水，从而保护了光纤的性能。
本发明还提供一种光纤连接座，其包括座体，所述座体至少一端设有连接座对接部，所述连接座对接部内设有对接通道，所述连接座对接部外侧设有外螺纹，且所述座体还设有用于容纳光纤插芯的插芯收容座，所述插芯收容座位于所述座体中部，所述插芯收容座伸入所述对接通道，且所述插芯收容座与所述连接座对接部内壁之间形成插槽。
在上述技术方案的基础上，所述插芯收容座的末端将所述对接通道分为靠近所述座体的第一段和远离所述座体第二段，且所述第二段的长度大于所述第一段的长度。
第二段足够长可提供有效的插入空间，从而提高连接的稳定性，并在第二段外围区域提供其他部件的位置。

以下结合附图及实施例对本发明作进一步详细说明。
实施例1：
参见图1和图2所示，本实施例提供一种光纤连接头，其包括主体部1、光缆2和插入部3。
其中，在主体部1设有一空腔10，空腔10主要用来容纳光缆2。光缆2组设于主体部1，并伸入空腔10。
主体部1的一端还设有插入部3，插入部3远离主体部1的一端设有光纤插芯30。在插入部3末端还设有围绕光纤插芯30的筒状结构31，筒状结构31主要用于插入与光纤连接头适配的光纤连接座的插槽43，筒状结构31与光纤插芯30间隔设置。
套设在筒状结构31上的连接头套筒32，其可沿筒状结构31滑动，且连接头套筒32至少部分位于光纤插芯30外。
由于在筒状结构31上还套设有连接头套筒32，当所述连接头套筒32滑动至远离所述主体部1的末端时，其至少部分连接头套筒32是位于光纤插芯30外的，这样连接头套筒32即可起到保护光纤插芯30的作用，能够防止光纤插芯30在光纤连接头在与光纤连接座对接前受损，从而能够保证光纤的性能。
此外，为了使光纤连接头整体性更强，插入部3与主体部1可以是一体成型，当然，为了生产方便，也可将插入部3组设于主体部1。
同时，由于连接头套筒32可以回缩，因此，与光纤连接头适配的光纤连接座无需额外设置承接连接头套筒32的空间，而设置承接连接头套筒32的空间需要使增加光纤连接座的直径以提供位置来设 置这一空间，从而可以有效的降低光纤连接座的直径，从而提高光纤连接座在面板上的密度。并且，由于连接头套筒32可以回缩，使得光纤连接头连接到光纤连接座后整体的长度变短。
实施例2：
作为一个较好的可选方式，本实施例与实施例1的差别在于：
筒状结构31与光纤插芯30之间形成一插入空间33。插入空间33的形状可以根据需要设置，为了起到更好的密封作用，本实施例中的插入空间33为环形。
实施例3：
作为一个较好的可选方式，本实施例与实施例1的差别在于：
光纤连接头还包括连接头对接部34，连接头对接部34围设在插入部3外侧，并从插入部3的始端延伸至筒状结构31处，连接头对接部34与插入部3间隔设置，且连接头对接部34靠近筒状结构31处设有内螺纹35。
在设置了连接头对接部34后，由于连接头对接部34设有内螺纹35，同时在与光纤连接头对接的光纤连接座上设置匹配的外螺纹46，即可简单快速的完成光纤连接头与光纤连接座的对接。
进一步的，光纤连接头还包括弹性件，弹性件用于对连接头套筒32施加远离所述主体部1方向的驱动力。
具体的，插入部3上套设有弹簧36，弹簧36即为上述的弹性件，弹簧36位于插入部3和连接头对接部34之间，且弹簧36的一端抵持或连接在连接头对接部34上，另一端抵持或固定连接在插入部3的上。
设置弹簧36后，在光纤连接头与光纤连接座对接后，弹簧36将会受到压缩，当需要将光纤连接头与光纤连接座分离时，弹簧36能 够提供驱动力，让连接头套筒32可以弹回保护光纤插芯30的位置。同时，筒状结构31上设有一对准结构39，所述连接头套筒32上设有与所述对准结构39位置对应的开槽320。
实施例4：
作为一个较好的可选方式，本实施例与实施例1的差别在于：插入部3和主体部1均为圆柱状，且插入部3直径小于主体部1直径。
将插入部3和主体部1均设置为圆柱状，可以与光纤连接座更好的配合和方便对接。由于插入部3直径小，从而可以有效的降低整体的直径，有效提高光纤连接组件的布置密度。
实施例5：
作为一个较好的可选方式，本实施例与实施例1的差别在于：插入部3的始端还设有密封件37。具体的：插入部3靠近所述主体部1的一端设有向连接头对接部34延伸的台阶38，台阶38上设有密封件37。当和光纤连接座对接后，光纤连接座的连接座对接部40抵持在密封件37上，从而可以防止水进入光纤插芯30的区域。
设置密封件37后，可以防止在光纤连接头与光纤连接座对接时漏水，从而保护了光纤的性能。
实施例6：
参见图3所示，本实施例还提供一种光纤连接座，其包括座体4，座体4至少一端设有连接座对接部40，连接座对接部40内设有对接通道41，连接座对接部40外侧设有外螺纹46，且座体4还设有用于容纳光纤插芯30的插芯收容座42，插芯收容座42位于座体4中部，插芯收容座42伸入对接通道41，且插芯收容座42与连接座对接部40内壁之间形成插槽43。
外螺纹46用来与连接头对接部34的内螺纹35配合使用，从而 简单方便的完成光纤连接头与光纤连接座的对接。
优选的，本实施例中的插芯收容座42的末端将对接通道41分为靠近座体4的第一段44和远离座体4第二段45，且第二段45的长度大于第一段44的长度。第二段45足够长可提供有效的插入空间，从而提高连接的稳定性，并在第二段45外围区域提供其他部件的位置。
优选的，插槽43的截面为环形。插槽43用于容纳与光纤连接座相匹配的光纤连接头的插入部3的筒状结构31和连接头套筒32。
优选的，插槽43的宽度与光纤连接座相匹配的光纤连接头的插入部3的筒状结构31和连接头套筒32的厚度相匹配。即插槽43可以很好的同时容纳筒状结构31和连接头套筒32，相匹配的厚度使得插入后能提供良好的密封性能。
实施例7：
参见图4所示，本实施例还提供一种光纤连接组件，其包括光纤连接头和光纤连接座。
光纤连接头包括主体部1；位于主体部1一端的插入部3，插入部3远离主体部1的一端设有光纤插芯30；插入部3末端还设有围绕光纤插芯30的筒状结构31，筒状结构31与光纤插芯30间隔设置；以及套设在筒状结构31上的连接头套筒32，其可沿筒状结构31滑动，且连接头套筒32至少部分位于光纤插芯30外；
光纤连接座包括座体4，座体4至少一端设有连接座对接部40，连接座对接部40内设有对接通道41，连接座对接部40外侧设有外螺纹46，且座体4还设有用于容纳光纤插芯30的插芯收容座42，插芯收容座42位于座体4中部，插芯收容座42伸入对接通道41，且插芯收容座42与连接座对接部40内壁之间形成插槽43。
具体的，当光纤连接头插入光纤连接座时，插入部3插入对接通道41，筒状结构31和连接头套筒32插入插槽43，插芯收容座42插入光纤插芯30和筒状结构31之间。
优选的，本实施例中的插芯收容座42的末端将对接通道41分为靠近座体4的第一段44和远离座体4第二段45，且第二段45的长度大于第一段44的长度。第二段45足够长可提供有效的插入空间，从而提高连接的稳定性，并在第二段45外围区域提供其他部件的位置。
优选的，插槽43的截面为环形。插槽43用于容纳与光纤连接座相匹配的光纤连接头的插入部3的筒状结构31和连接头套筒32。
优选的，插槽43的宽度与光纤连接座相匹配的光纤连接头的插入部3的筒状结构31和连接头套筒32的厚度相匹配。即插槽43可以很好的同时容纳筒状结构31和连接头套筒32，相匹配的厚度使得插入后能提供良好的密封性能。
优选的，筒状结构31上设有一对准结构39，所述连接头套筒32上设有与对准结构39位置对应的开槽320，连接座对接部40具有对准匹配结构400，当所述光纤连接座与所述光纤连接头对接时，所述对准匹配结构400穿过所述开槽320并与所述对准结构39相匹配接合。以使光纤连接头能以设定的角度插入光纤连接座。保证光纤对接后的传输。同时，开槽320的作用是为对准匹配结构400插入时进行让位，使得对准匹配结构400和对准结构39的匹配接合成为可能。
本发明不局限于上述实施方式，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
