Description

一种光纤连接器 技术领域
本文涉及光通讯的物理连接技术领域，例如涉及一种光纤连接器。
背景技术
光纤连接器，是光纤与光纤之间进行可拆卸(活动)连接的器件，它把光纤的两个端面精密对接起来，以使发射光纤输出的光能量能最大限度地耦合到接收光纤中去。
如图1所示，相关技术提出一种光纤连接器，包括连接器主体1′和固定在连接器主体1′的一端以保护光缆9′的尾套8′，光缆9′通过尾套8′插入连接器主体1′中与插芯10′的一端对接，插芯10′的另一端从连接器主体1′的另一端露出；还包括锁定机构2’，锁定机构2′包括从连接器主体1′的外部倾斜延伸形成的具有弹性的倾斜臂21′、从倾斜臂21′的两侧凸出的锁定凸起22′和与倾斜臂21′连接的驱动臂23′。当将光纤连接器插入到适配器中时，锁定凸起22′配合在适配器的锁定槽中，而驱动臂23′的末端露出在适配器的外部，这样，锁定槽锁住锁定凸起22′，从而使得整个光纤连接器不能从适配器中直接拔出。当需要分离适配器和光纤连接器时，操作人员将按压驱动臂23′的末端，带动倾斜臂21′的末端向连接器主体1′的外部靠近，从而带动锁定凸起22′脱离锁定槽，这样就可以将光纤连接器从适配器中拔出。
上述光纤连接器的不足之处在于，必须在用于安装适配器的安装面板上预留充分的操作空间，以确保对驱动臂23′进行按压操作，因此，导致光纤连接器占据的空间较大，安装面板上相邻的适配器不能实现高密度堆栈排布，从而影响了安装面板的安装密度。
相关技术中虽然也有通过拉动拉把解锁连接器主体与适配器之间的锁定的光纤连接器，但是，是由拉把直接拉动驱动臂的末端移动，带动倾斜臂的末端向连接器主体的外部靠近，从而带动锁定凸起脱离锁定槽，存在操作费力的缺点。

具体实施方式
下面结合附图和实施方式进一步说明本文的技术方案。可以理解的是，此 处所描述的具体实施例仅仅用于解释本文，而非对本文的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本文相关的部分而非全部。
如图2-图12所示，本文提供一种光纤连接器，用于连接至适配器，可以将连接器和适配器各自连接的光缆的光纤进行接续、分配或者转接。本文一实施例提供的一种光纤连接器包括连接器主体1、锁定机构2、运动转换组件3、框架4和拉把7，其中，连接器主体1的第一端可插接到适配器中，连接器主体1的第二端与框架4的第一端连接，框架4的第二端与用于插入光缆9的尾套8连接；锁定机构2包括倾斜臂21、锁定凸起22和驱动臂23，倾斜臂21从连接器主体1向上倾斜延伸，锁定凸起22从倾斜臂21的侧部向外凸出，用于将连接器主体1锁定到适配器的锁定槽中，驱动臂23的第一端与倾斜臂21连接，驱动臂23的第二端与运动转换组件3的第一端连接，运动转换组件3的第二端与拉把7连接，运动转换组件3可将拉把7的平动转换为自身的转动。运动转换组件(3)与框架(4)枢接，驱动臂(23)的第二端与驱动臂(23)的第一端相对，运动转换组件(3)的第二端与运动转换组件(3)的第一端相对。
拉动拉把7可带动运动转换组件3转动，从而按压驱动臂23的第二端，并带动与驱动臂23的第一端连接的倾斜臂21向水平方向靠近，当倾斜臂21与水平方向的夹角小于一定角度时，锁定凸起22从适配器的锁定槽中脱离，从而解除连接器主体1与适配器之间的锁定。
本文提供的光纤连接器，通过拉动拉把7就可以解除连接器与适配器之间的锁定，避免了只有从连接器的上方按压驱动臂23才能使锁定凸起22脱离锁定槽，最大限度的减小了插拔连接器时用于按压驱动臂23所需要的操作空间，允许多个适配器和/或连接器相互堆栈成最紧密的排列，即使得适配器和/或连接器能以更高的密度进行安装；此外，拉把7与驱动臂23之间通过运动转换组件3相连，运动转换组件3设置为将拉把7的平动转化为运动转换组件3的转动，操作时，只需轻轻拉动拉把7，就能带动运动转换组件3转动，从而使运动转组件3与驱动臂23配合的一端按压驱动臂23，使锁定凸起22脱离锁定槽，操作十分方便、省力。
参见图2-图9，运动转换组件3包括翻板31和拉把滑块32，其中，翻板31的中部与框架4枢接，翻板31可绕其枢接轴线转动，翻板31的第一端与驱动 臂23的第二端配合，翻板31的第二端与拉把滑块第一部分321配合，其中，所述翻板(31)的第二端与所述翻板(31)的第一端相对。拉把滑块第二部分322与拉把7可拆卸连接，拉把滑块32可滑动地设置在框架4上。拉把7被拉动时，能够带动拉把滑块32滑动，拉把滑块(32)的滑动能够带动翻板31转动。
在一实施例中，拉把滑块第一部分321的下端面设置有向下凸出的第一滑动凸起3213，相应的，框架4上设置有沿拉把7的移动方向延伸的第一滑动槽41，第一滑动凸起3213可沿第一滑动槽41滑动；拉把滑块第一部分321的上端面设置有向上凸出的驱动块3211，相应的，翻板31的第二端设置有向下延伸的滑动延伸部312，该滑动延伸部312与驱动块3211配合的面为倾斜面；当拉把7被拉动时，拉把7带动拉把滑块32沿第一滑动槽41向远离连接器主体1的方向移动，同时拉把滑块32上端的驱动块3211与翻板31的滑动延伸部312的倾斜面发生相对滑动，从而驱动翻板31转动，使翻板31的第一端按压驱动臂23的第二端。在一实施例中，在翻板31的第一端上且与驱动臂23的第二端配合的面为按压面311，该按压面311为弧形面，相应的，驱动臂23的第二端的边缘向按压面311方向折弯形成折弯部，该折弯部与按压面311可移动的结合。
第一滑动凸起3213与第一滑动槽41之间滑动阻力小，在拉把7上施加很小的拉动力，就能够带动拉把滑块32滑动，拉把滑块32滑动时，驱动块3211沿滑动延伸部312的倾斜面滑动，从而驱动翻板31转动，驱动块3211与倾斜面之间的滑动阻力小，拉把滑块32能够很容易带动翻板31转动，整体运动流畅，操作时，十分方便、省力。
在一实施例中，为保证驱动块3211与滑动延伸部312的倾斜面之间滑动的流畅度，将驱动块3211与倾斜面接触的部分设置为圆弧形；另外，为保证滑动延伸部312的倾斜面的滑动行程，同时又避免驱动块3211凸出于拉把滑块32的高度过大，在拉把滑块第一部分321的上端面且在驱动块3211与拉把滑块第二部分322之间开设有容纳槽3212，滑动延伸部312的下端可延伸至容纳槽3212内；此外，在拉把滑块32的侧部凸出有限位凸起，能够防止拉把滑块32在框架4中发生翻转。
在一实施例中，拉把7可以为软拉把，也可以为硬拉把，当为软拉把时，只能通过拉把7拉动运动转换组件3，使运动转组件3向按压驱动臂23的方向转动；当为硬拉把时，既能通过拉把7拉动运动转换组件3，使运动转组件3向按压驱动臂23的方向转动，又能通过拉把7推动运动转换组件3，使运动转组件3向与按压驱动臂23相反的方向转动。
在一实施例中，参见图6以及图10-图12，光纤连接器还包括设置在框架4的内部的组装夹6，组装夹6用于结合连接器主体1和尾套8。组装夹6的用于结合尾套8的第二端设置有螺纹连接部，该螺纹连接部能增大与尾套8连接的摩擦力，防止光缆9中的凯夫拉纤维脱出。框架4可拆卸的套设在组装夹6的外部。在一实施例中，框架4的底面的一部分为活动连接部42，该活动连接部42具有弹性，该活动连接部42朝向组装夹6的一侧设置有固定凸起43，组装夹6上设置有与固定凸起43对应的固定槽，当需要将框架4与组装夹6分离时，只需掰动活动连接部42，使固定凸起43脱离固定槽即可将框架4抽出。
在一实施例中，连接器主体1的数量为两个，为保持两个连接器主体1并排分隔的设置，在组装夹6的第一端设置有两个安装槽61，每个连接器主体1通过一个框套5可拆卸的设置在一个安装槽61中。例如，框套5的第一部分与连接器主体1的第二端连接，框套5的第二部分与安装槽61可拆卸连接。在一实施例中，安装槽61的两相对侧壁上设置有贯通的第二滑动槽611，框套5的侧部凸出有与第二滑动槽611相对应的第二滑动凸起51，在外力作用下，第二滑动凸起51沿着第二滑动槽611滑动可使框套5装入或脱出组装夹6。
在组装夹6的第二端设置有与尾套8连通的通孔，光缆9穿过尾套8进入尾套8内部，之后穿过通孔，之后将光缆9的保护套剥离，露出光纤，光纤穿过组装夹6的安装槽61和框套5后进入连接器主体1的内部，在连接器主体1的内部设有光纤固定装置，光纤通过光纤固定装置固定之后连接至插芯10。
当需要更换两个连接器主体1的位置时，首先将翻板31的第一端与驱动臂23的第二端脱开，然后掰动框架4的活动连接部42，使固定凸起43与固定槽脱开，即可将框架4连同运动转换组件3整体拆下，然后将两个与连接连接器主体1连接的框套5分别从各自对应的安装槽61中滑出，互换连接器主体1的位置后，再将两个与连接连接器主体1连接的框套5滑入互换位置后的各自的 安装槽61中，最后将框架4连同运动转换组件3一起套设在组装夹6的外部即可。
本文实施例提供的光纤连接器，具有解除与适配器之间的锁定时占用操作空间小、操作省力，以及两个连接器主体1之间互换位置方便的多重优势。
图13是本文一实施例提供的光纤连接器1”在一个角度的结构示意图。图14是本文一实施例提供的光纤连接器1”在另一个角度的结构示意图。如图13和图14所示，本文实施例提供的光纤连接器1”连接有光纤，两个光纤连接器1”通过插接在适配器上，实现两个光纤连接器1”上光纤14”的端面精密对接，以使发射光纤输出的光能量能最大限度地耦合到接收光纤14”中去，并使由于其介入光链路而对系统造成的影响减到最小。
图15是本文一实施例提供的拉把在一个角度的机构示意图。如图13～图15所示，本文实施例提供的光纤连接器1”包括框架15”、连接器主体11”和拉把13”，其中，拉把13”设置在框架15”上，连接器主体11”插接在框架15”中，连接器主体11”的尾部连接有尾套16”，连接器主体11”和尾套16”用于穿设光纤14”。本实施例通过拉把13”设有一侧开口的容置槽131”，尾套16”能从开口容置在容置槽131”中，使拉把13”与光纤14”不会存在较大的缝隙，可以防止其他的光纤卡入到该光纤连接器1”及所连接的光纤14”之间，避免拔出不同光纤连接器1”时，不同的光纤连接器1”上的光纤14”相互缠绕，减少操作人员分开缠绕在一起的光纤14”所消耗的时间和精力，避免光纤14”在分离过程中出现的折断现象。
当然，在其他实施例中，可以是至少部分光纤14”能从开口容置在容置槽中，还可以是至少部分尾套16”和至少部分光纤14”均能从开口容置在容置槽中，也能够实现上述效果。
在其他实施例中，容置槽131”不仅仅可以在一侧开口，还可以在多侧进行开口，尾套16”还可以是部分容置在容置槽131”中，也能够实现上述技术效果。
如图13～图15所示，本实施例提供的光纤连接器1”还包括运动转换机构12”。其中，连接器主体11”设置在框架15”上，连接器主体11”上设置有锁定臂111”，运动转换机构12”与框架15”转动连接，拉把13”可沿框架15”滑动， 且与运动转换机构12”的一端相连接，运动转换机构12”能将拉把13”的平动转换为自身的转动，使运动转换机构12”的另一端能与锁定臂111”相抵接或分离。
示例性的，尾套16”的材料可以是热塑性弹性体(Thermoplastic Elastomer，TPE)，TPE是一种具有橡胶的高弹性，高强度，高回弹性。能够保证光纤连接器1在脱离适配器、自由放置的状态(非安装状态)下，尾套16”可在弹性材料的作用下恢复，容置在容置槽131”中，尽量减少与拉把13”之间的间隙，可以有效避免与其他光纤之间的交缠。同时，由弹性材料制成的尾套16”还可以保证光纤连接器1”在使用时，尾套16”可以随光纤弯曲。尾套16”可以从容置槽131”的开口中脱落出，实现光纤14”在张紧状态下的弯曲。
例如，操作者将光纤连接器1”的连接器主体11”拔出服务器机柜的过程中，向后拉拉把13”，运动转换机构12”与锁定臂111”相抵接时，方便光纤连接器1”的拔出。且操作者手持光纤14”，光纤14”和尾套16”在尾套16”弹性恢复力的作用下，可使至少部分尾套16”容置在容置槽131”中，可以防止光纤连接器1”上的零部件卡入到其他光纤连接器1”上的拉把13”与光纤14”之间，避免拔出不同光纤连接器1”时，不同的光纤连接器1”之间相互缠绕，减少操作人员分开缠绕在一起的光纤连接器1”所消耗的时间和精力，避免光纤14”在分离过程中出现的折断现象。另外，当光纤连接器1”在已经安装到机柜后，在光纤14”自身的重力和尾套16”的弹性材料的共同作用下，光纤14”可以从容置槽131”的开口中脱出，不会影响尾套16”及光纤14”在张紧状态下的弯曲度，实现光纤连接器1”的正常使用。
在其他实施例中，通过更改容置槽131”的形状，在尾套16”的弹性恢复力的作用下，保证至少部分光纤14”设置在容置槽131”中，且与拉把13”相抵接；或保证至少部分尾套16”和至少部分光纤14”同时容纳在容置槽131”中，且与拉把13”相抵接，也能够实现上述技术效果。
如图13所示，在本实施例中，当尾套16”容置在容置槽131”中时，拉把13”的自由端设置为不超过尾套16”的自由端，比如，拉把13”的自由端可以比尾套16”的尾端靠近连接器主体11”，也可以是拉把13”的自由端可以比尾套16”的尾端平齐，即，拉把13”的自由端设置为凸出尾套16”的尾端0mm，容置槽131”的形状仅与尾套16”的形状相匹配即可。通过上述设置，在拔出光纤连 接器1”的过程中，以及光纤连接器1”平时的存储中，能够保证尾套16”容置在容置槽131”中，避免拉把13”与尾套16”之间出现缝隙。在其他的实施例中，拉把13”的自由端也可以超过尾套16”的尾端。但是由于光纤的宽度比尾套的宽度要小，如果拉把超出尾套太长，拉把和尾套之间仍然会有一定的空隙，相邻的光纤可能会插入到空隙中。因此拉把13”的自由端设置为超过尾套16”的尾端不超过20mm，容置槽的形状设置为分别与尾套16”及光纤14”相匹配。
在一实施例中，拉把13”靠近其自由端的位置设置有夹持部132”，夹持部132”围设形成U形的容置槽131”。当运动转换机构12”与锁定臂111”相抵接时，至少部分尾套16”被夹持部132”夹紧。例如，夹持部132”沿长度方向的向中间位置收缩，从而能够实现夹持部132”对于尾套16”更好的夹持作用。
在一实施例中，如图15所示，拉把13”的外侧靠近拉把13”的自由端的位置设置有防滑结构133”，可以提高拉把13”与手之间的摩擦力，便于操作者对拉把13”的把持效果，例如，防滑结构133”可以是若干条相间隔设置的条形凸起。
在一实施例中，拉把13”由硬质材料制成，可以由聚碳酸酯(Polycarbonate，PC)或丙烯腈-苯乙烯-丁二烯共聚物(Acrylonitrile Butadiene Styrene，ABS)制成，具有较好的支撑效果，方便操作者对拉把13”的推拉。
图16是本文一实施例提供的光纤连接器1”的剖视图。在本实施例中，如图16所示，框架15”的内部设置有组装夹23”，用于结合连接器主体11”和光纤14”，框架15”与组装夹23”可拆卸连接，方便组装夹23”的更换。
图17是本文一实施例提供的框架的结构示意图。在本实施例中，如图16所示，并结合图15和图17，在本实施例中，拉把13”上凸设有限位块19”，框架15”上开设有限位孔20”，限位块19”容置在限位孔20”中，且可沿限位孔20”滑动。一方面，通过限位块19”和限位孔20”相配合，实现对于拉把13”两种状态下极限位置的限定，在本实施例中的两种状态是指：锁定臂111”处于压缩的状态和锁定臂111”处于弹出的状态；另一方面，限位孔20”对限位块19”有一定的导向作用，防止拉把13”沿框架15”滑动过程中出现偏斜。
在其他实施例中，还可以是在拉把13”上开设有限位孔，在框架15”上凸设有限位块，也能够实现上述效果。
图18是本文一实施例提供的拉把在另一个角度的机构示意图，图19是本文一实施例提供的运动转换机构的结构示意图。在本实施例中，如图16所示，并结合图18和图19，在本实施例中，示例性的，拉把13”上凸设有驱动块17”，运动转换机构12”上设置有斜面18”，驱动块17”与斜面18”相配合，驱动运动转换机构12”相对于框架15”的转动。例如，以图16为参考图，规定连接器主体11”所处位置为前，光纤14”所处位置为后。当向后拉动拉把13”，使驱动块17”与斜面18”相接触，驱动块17”驱动运动转换机构12”相对于框架15”顺时针转动，位于前端的运动转换机构12”对锁定臂111”有向下的压力，使锁定臂111”处于压缩状态，操作者可以顺利将处于此状态的光纤连接器1”从适配器(图中未示出)中拔出；当向前推拉把13”时，驱动块17”与斜面18”分开，斜面18”不受拉把13”的推力，从而使得运动转换机构12”与锁定臂111”相分离，锁定臂111”处于张紧状态，从而保证光纤连接器1”与适配器的紧密连接。
在其他实施例中，还可以是在拉把13”上设置有斜面，在运动转换机构12”上凸设有驱动块，通过驱动块与斜面的配合，实现上述效果。
在本实施例中，如图18和图19所示，示例性的，拉把13”上开设有导向槽21”，运动转换机构12”上凸设有导向块22”，导向块22”容置在导向槽21”中，且可沿导向槽21”滑动，从而实现运动转换机构12”相对于拉把13”相对滑动的导向作用。
在其他实施例中，还可以是在拉把13”上凸设有导向块，在运动转换机构12”上开设有导向槽，通过导向块容置在导向槽中，且可沿导向槽滑动，也能够实现上述效果。
工业实用性
本文实施例减小了插拔连接器时用于按压驱动臂所需要的操作空间，使适配器和连接器可以实现更高密度的安装，且在插拔连接器时操作方便、省力。
