Description

光口适配器、收发器及光口连接组件 技术领域
本申请涉及光纤技术领域，尤其涉及一种光口适配器、收发器及光口连接组件。
背景技术
2017年扇港(Senko)公司推出了最新的CS连接器(也可以称为CS跳线)，作为行业的一种新光口连接方式，具有低插入损耗、高光纤密度、简易安装以及高稳定性能等优势，适用于400G新一代数据中心的新型双芯连接器。与LC(lucent connector)连接器相比，CS连接器外形尺寸也更小，同时由于CS连接器采用抽拉式的解锁机构，在垂直方向上不需要预留人手操作空间，从而相比于LC具有更高密度的堆叠优势。
光口适配器的端口通过尖钩(hook)结构与CS连接器配合，来控制CS连接器的自锁与解锁，以满足CS连接器的插拔，尖钩(hook)的设计是CS连接器实现可靠插拔以及连接的关键；现有的尖钩结构复杂且不易安装，从而导致光口适配器的成本上升。
发明内容
本申请提供一种光口适配器、收发器及光口连接组件，能够满足CS连接器实现可靠插拔的基础上，简化光口适配器的结构。
本申请提供一种光口适配器，包括端口以及卡接在端口内部的至少一个线型连接器挂钩。其中，所述端口内部在与所述端口的入口相对一侧的第一侧壁设置有光纤接口；所述线型连接器挂钩包括：线型自锁结构和两个线型支撑结构；所述线型自锁结构包括一个解锁凸出部以及位于所述解锁凸出部两侧、且与所述解锁凸出部的两端分别连接的两个卡合凹陷部；所述解锁凸出部朝向所述端口的顶部一侧凸出，所述卡合凹陷部朝向所述端口的底部一侧凹陷；所述卡合凹陷部与所述端口的底部之间具有间隙；两个所述线型支撑结构各自的第一端分别与所述线型自锁结构连接的两端连接，且两个所述线型支撑结构关于所述线型自锁结构对称设置；所述线型支撑结构的第二端相对于所述第一端靠近所述第一侧壁，且所述线型支撑结构的第一端相对于所述第二端靠近所述端口的底部。
本申请实施例采用的光口适配器通过端口内部设置的线型连接器挂钩结构与CS连接器之间的卡锁和解锁，该线型连接器挂钩采用线材(例如不锈钢丝)，结构简单；并且该线型连接器挂钩直接卡接在端口内部，组装方便；进而也就降低了光口适配器的成本。
在一些可能实现的方式中，所述线型支撑结构包括中间连接部、从所述中间连接部的一端延伸到所述第一端的第一弯钩、从所述中间连接部的另一端延伸到所述第二端的第二弯钩；所述第一弯钩向所述端口的底部一侧弯折，所述第二弯钩向所述端口的顶部一侧弯折；所述第二端与所述端口的顶部接触。
在此情况下，两个线型支撑结构近似呈“Z”型结构，从而保证两个线型支撑结构在上下方向(也即端口底部到顶部的方向上)具有一定伸缩弹性，保证跳线方便插入光口以及拉动拉带时解锁跳线，同时能够在上下方向上挤压更好的固定线型连接器 挂钩。
在一些可能实现的方式中，所述第二弯钩在末端通过线型固定段延伸到所述第二端，所述线型固定段与所述端口的顶部平行且接触。这样一来，通过增加两个线型支撑结构与端口顶部的接触面积，提高了线型连接器挂钩卡接在端口中的稳定性。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书实施例和权利要求书及附图中的术语“第一”、“第二”等仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列结构或单元。系统、产品或设备不必限于清楚地列出的那些结构或单元，而是可包括没有清楚地列出的或对于这些产品或设备固有的其它结构或单元。“上”、“下”、“左”、“右”等仅用于相对于附图中的部件的方位而言的，这些方向性术语是相对的概念，它们用于相对于的描述和澄清，其可以根据附图中的部件所放置的方位的变化而相应地发生变化。
本申请实施例提供一种收发器，该收发器包括光电转换模块以及与该光电转换模块连接的光口适配器；光电转换模块具有收端和发端，光口适配器中设置分别套装在光电转换模块的收端和发端上的光纤接口。
光口适配器作为连接器与光电转换模块之间的中间连接结构，能够保证两者之间的稳定连接，在使用时，连接器的一组光纤插芯(例如光纤陶瓷插芯)通过插入光口适配器的光纤接口，分别与光电转换模块的收端和发端连接；在将连接器从光口适配器的端口中拔出后，连接器的光纤插芯与光电转换模块断开。
示意的，上述连接器可以为CS连接器，但并不限制于此，以下实施例均是以此为例 进行说明的。另外，本申请对光口适配器适用的收发器的插拔模块的类型不做限制，例如可以适用于QSFP28(quad small form-factor pluggable，4通道小型可插拔模块)，也可以适用于QSFP-DD(quad small form factor pluggable-double density，双密度四通道小型可插拔模块)等。
当然，该收发器中还设置有其他的器件，此处不再一一赘述。例如，收发器中还可以设置有印刷线路板(printed circuit board，PCB)，通过PCB与载板连接。
本申请实施例提供的收发器中的光口适配器的端口内部采用线型连接器挂钩(hook)，该线型连接器挂钩结构简单、组装方便，能够在保证CS连接器与光口适配器的端口之间实现顺利插拔的基础上，降低光口适配器的成本。
另外，本申请实施例还提供一种光口连接组件，包括CS连接器以及前述的收发器。
如图1所示，该CS连接器包括位于端部(也可以称为前端)的一组(即两个)光纤插芯01、推拉舌片02以及并列设置的两个卡合主体03。
结合图1和图2，在将CS连接器的光纤插芯01插入至光口适配器的光纤接口04(参考图2)过程中，并列设置的两个卡合主体03与线型连接器挂钩H(hook)卡锁，从而使得CS连接器的一组光纤插芯通过分别光纤接口04与光电转换模块的入端和出端连通。在通过拉带拉动推拉舌片02朝远离光口适配器一侧移动时，推拉舌片02对线型连接器挂钩H进行抬升，CS连接器的两个卡合主体03与线型连接器挂钩H解锁，从而能够顺利将CS连接器的光纤插芯01拔出光口适配器的光纤接口04，CS连接器与光电转换模块的入端和出端断开。
以下对本申请实施例提供的光口适配器做进一步的说明。
本申请实施例提供的一种光口适配器，如图2所示，该光口适配器包括端口以及卡接在端口内部的至少一个线型连接器挂钩H。例如，可以在端口内部内设置两个线型连接器挂钩H。
参考图2和图3(图2的光口适配器的端口在入口一侧的侧面示意图)所示，端口内部在与端口的入口一侧相对的第一侧壁(也可以称为远端侧壁)设置有分别套接在光电转换模块的入端(R1、R2)和出端(T1、T2)上的光纤接口04，以在CS连接器插入光口适配器的端口后，CS连接器的一组光纤插芯能够分别通过不同的光纤接口04与光电转换模块的入端和出端连接。
另外，如图2所示，本申请的光口适配器中采用的线型连接器挂钩H为线型结构，构造简单，易于制作。如图4所示，该线型连接器挂钩H包括线型自锁结构Z3以及两个线型支撑结构，两个线型支撑结构分别为：第一线型支撑结构Z1和第二线型支撑结构Z2。
结合图2和图3、图4所示，线型自锁结构Z3包括一个解锁凸出部1以及位于解锁凸出部两侧、且与解锁凸出部1的两端分别连接的两个卡合凹陷部(第一卡合凹陷部2_1和第二卡合凹陷部2_2)。其中，解锁凸出部1朝向端口的顶部一侧凸出，两个卡合凹陷部(2_1、2_2)朝向端口的底部一侧凹陷；并且两个卡合凹陷部(2_1、2_2)与端口的底部之间具有间隙。
第一线型支撑结构Z1包括第一端a1和第二端a2，其中，第一端a1相对于第二端a2靠近端口的入口(也即第二端相对于第一端靠近前述的第一侧壁；或者，第一 端位于端口内部的近端一侧，第二端位于端口内部的远端一侧)。同样第二线型支撑结构Z2包括第一端b1和第二端b2，其中，第一端b1相对于第二端b2靠近端口的入口。并且两个线型支撑结构(Z1、Z2)的第一端(a1、b1)相对于第二端(a2、b2)靠近端口的底部。
另外，结合图2和图4所示，线型自锁结构Z3连接在第一线型支撑结构Z1的第一端a1和第二线型支撑结构Z2的第一端b1之间，且两个线型支撑结构(Z1、Z2)关于线型自锁结构Z3对称设置。
结合图1、图2、图3、图4所示，在将CS连接器的光纤插芯01插入至光口适配器的光纤接口04的过程中，CS连接器前端的两个卡合主体03分别从两个卡合凹陷部(2_1、2_2)与端口的底部之间具有间隙伸入，两个卡合凹陷部(2_1、2_2)分别卡入两个卡合主体03上的凹槽s中，从而在CS连接器与光口适配器卡锁(也即自锁)的基础上，保证CS连接器的一组光纤插芯与光电转换模块的入端(例如R1)和出端(例如T1)稳定连通。在通过拉带拉动推拉舌片02朝远离光口适配器一侧拉动的过程中，位于推拉舌片02上表面的倾斜坡面u会整体抬升线型连接器挂钩H，从而使得两个卡合凹陷部(2_1、2_2)脱离两个卡合主体03的凹槽s，CS连接器与光口适配器解锁，以便CS连接器能够顺利从光口适配器的端口中拔出。
需要说明的是，本申请实施例中所涉及的“远端”(也可以称为“后端”)、“近端”(可以称为“前端”)仅是一个相对概念。本领域的技术人员可以理解的是，对于光口适配器而言，光口适配器与CS连接器最先接触的一侧视为“近端”(前端)，也即光口适配器的入口一侧为“近端”(前端)；当然，与“近端”(前端)相对的一端即为“远端”(后端)。类似的，对于CS连接器而言，CS连接器与光口适配器最先接触的一侧视为“近端”(前端)。
综上所述，本申请实施例采用的光口适配器通过端口内部设置的线型连接器挂钩结构与CS连接器之间实现卡锁和解锁，该线型连接器挂钩采用线材(例如不锈钢丝等)，结构简单；并且该线型连接器挂钩直接卡接在端口内部，组装方便；进而也就降低了光口适配器的成本。
本申请实施例中对于光口适配器内部设置的线型连接器挂钩H的数量不做限制，实际中可以根据需要选择设置线型连接器挂钩H的数量。示意的，在一些可能实现的方式中，如图2所示，该光口适配器的端口的内部设置两个线型连接器挂钩H；也即该光口适配器为双工适配器；在此情况下，两个CS连接器可以通过该光口适配器与光电转换模块连接，该光电转换模块可以包括两个入端(R1、R1)和两个出端(T1、T1)。
以下对本申请中的线型连接器挂钩H的具体结构作进一步的说明。
如图4所示，在一些实施例中，该线型连接器挂钩H中的第一线型支撑结构Z1和第二线型支撑结构Z2的结构相同，且两者关于线型自锁结构Z3对称设置；下文均是以此为例进行说明的。
在一些可能实现的方式中，如图2和图4所示，第一线型支撑结构Z1包括中间连接部10、从中间连接部10的一端延伸到第一端a1的第一弯钩11、从中间连接部10的另一端延伸到第二端a2的第二弯钩12；其中，第一弯钩11向端口的底部一侧 弯折，第二弯钩12向端口的顶部一侧弯折，且第二端a2与端口的顶部接触。
同样，第二线型支撑结构Z2包括中间连接部20、从中间连接部20的一端延伸到第一端b1的第一弯钩21、从中间连接部20的另一端延伸到第二端b2的第二弯钩22；其中，第一弯钩21向端口的底部一侧弯折，第二弯钩22向端口的顶部一侧弯折；第二端b2与端口的顶部接触。
在此情况下，两个线型支撑结构(Z1、Z2)近似呈“Z”型结构，从而保证两个线型支撑结构(Z1、Z2)在上下方向(也即端口底部到顶部的方向上)具有一定伸缩弹性，保证跳线方便插入光口以及拉动拉带时解锁跳线，同时能够在上下方向上挤压更好的固定线型连接器挂钩H。
在一些可能实现的方式中，结合图2和图5所示，可以在光口适配器的端口的顶部对应线型连接器挂钩H的位置设置可拆卸的盖板05，这样一来，能够在未安装盖板05之前，从端口顶部的开口将线型连接器挂钩H置入端口内部，然后将盖板05放置在端口顶部并进行固定，通过盖板05对两个线型支撑结构(Z1、Z2)的第二端(a2、b2)的挤压，以在上下方向上对线型连接器挂钩H进行很好的固定。
示意的，在一些可能实现的方式中，参考图2，光口适配器可以在位于端口远端的主体顶部设置螺纹孔，盖板05通过螺钉与螺纹孔的配合安装在光口适配器的顶部。
另外，为了保证两个线型支撑结构(Z1、Z2)的第二端(a2、b2)与端口顶部的盖板很好的接触，进一步有效在上下方向上对线型连接器挂钩H进行固定，在一些可能实现的方式中，如图4所示，可以设置第一线型支撑结构Z1的第二弯钩12的末端通过线型固定段c1延伸到第二端a2，该线型固定段c1与端口顶部(如盖板的下表面)平行且接触；也即第一线型支撑结构Z1在第二弯钩12的末端设置有与端口顶部平行且接触线型固定段c1；同样，可以设置第二线型支撑结构Z2的第二弯钩22的末端通过线型固定段c2延伸到第二端b2；这样一来，增加了两个线型支撑结构(Z1、Z2)与端口顶部的接触面积，进而提高了线型连接器挂钩H卡接在端口中的稳定性。
示意的，在一些实施例中，第一线型支撑结构Z1的第二弯钩12的末端与线型固定段c1之间的夹角β1为165°～175°。例如，在一些可能实现的方式中，β1可以设置为165°；在一些可能实现的方式中，β1可以设置为170°；在一些可能实现的方式中，β1可以设置为175°。同样，在与第一线型支撑结构Z1对称设置的第二线型支撑结构Z2中，第二弯钩22的末端与线型固定段c2之间的夹角与β1的大小可以相同，也可以为165°～175°。
对于连接在两个线型支撑结构(Z1、Z2)的第一端(a1、a2)之间的线型自锁结构Z3而言，在一些可能实现的方式中，如图4所示，第一卡合凹陷部2_1相对于第二卡合凹陷部2_2靠近第一线型支撑结构Z1，可以设置第一卡合凹陷部2_1位于外侧的端部直接与第一线型支撑结构Z1的第一端a1连接，第二卡合凹陷部2_2位于外侧的端部直接与第二线型支撑结构Z2的第一端b1连接，第一卡合凹陷部2_1和第二卡凹陷部2_2位于内侧的两个端部横向连接形成解锁凸出部1；以保证线型连接器挂钩的具有紧凑的设置结构。
在一些可能实现的方式中，如图4所示，可以设置线型连接器挂钩H在所有的弯折部分均采用弧形倒角结构，以降低线型连接器挂钩H在弯折位置的集中应力。
另外，为了保证线型连接器挂钩H在上下方向上能够稳定、可靠的卡接在端口中，在一些实施例中，如图4所示，在第一线型支撑结构Z1中，可以设置中间连接部10与第二弯钩12之间的夹角β2为10°～30°，中间连接部10与第一弯钩12之间的夹角β3为30°～50°。示意的，在一些可能实现的方式中，β2可以为10°、20°或者30°；β3可以为30°、40°或者50°。
同样，与第一线型支撑结构Z1对称设置的第二线型支撑结构Z2中，可以设置中间连接部20与第二弯钩22之间的夹角大小与β2相同，该夹角可以为10°～30°；中间连接部20与第一弯钩21之间的夹角大小与β3相同，该夹角可以为30°～50°。
在一些可能实现的方式中，为了保证该线型连接器挂钩H的强度，该线型连接器挂钩H可以采用金属材质，例如不锈钢、铜、铝等；但并不限制于此，在一些可能实现的方式中，该线型连接器挂钩H的也可以采用塑料制成。
在一些可能实现的方式中，该线型连接器挂钩H为线型的一体结构，采用线材挤压成型，从而在保证线型连接器挂钩的强度的同时，简化线型连接器挂钩的制作工艺。示意的，线材可以采用不锈钢丝。
另外，以下对光口适配器的端口中，固定线型连接器挂钩H的限位结构进行具体说明。
如图2和图6所示，光口适配器的端口内部在位于两个线型支撑结构(Z1、Z2)靠近端口的入口一侧分别设置第一限位凸台t1、第二限位凸台t2；第一线型支撑结构Z1卡接在第一限位凸台t1与端口的第一侧壁(即设置光纤接口04的远端侧壁)之间，第二线型支撑结构Z2卡接在第二限位凸台t2与第一侧壁之间。
结合图2和图6所示，第一限位凸台t1和第二限位凸台t2之间形成有开口F，开口F的位置与线型自锁结构Z3中的解锁凸出部1以及两个卡合凹陷部(2_1、2_2)的位置相对，以保证CS连接器前端的推拉舌片02和两个卡合主体03通过该开口F插入至端口内部实现对线型连接器挂钩H的卡锁和解锁。
也就是说，线型连接器挂钩H在第一方向XX’(即端口的近端到远端的方向)上，通过位于靠近端口的入口一侧的两个限位凸台(t1、t2)与第一侧壁(远端侧壁)实现限位。
结合图2和图6所示，光口适配器的端口内部，在沿第二方向YY’(即两个线型支撑结构的并列设置的方向)上，位于两个线型支撑结构(Z1、Z2)的外侧分别设置有侧面限位凸台(n1、n2)，线型连接器挂钩H在沿第二方向YY’上卡接在两个侧面限位凸台(n1、n2)之间，也即沿第二方向YY’上，第一线型支撑结构Z1的外侧与第一侧面限位凸台n1接触，第二线型支撑结构Z1的外侧与第二侧面限位凸台n2接触。也就是说，线型连接器挂钩H在第二方向YY’上，通过位于两侧设置的侧面限位凸台(n1、n2)进行限位。
另外，结合图2和图6所示，光口适配器的端口内部在位于两个线型支撑结构(Z1、Z2)的下方分别设置有底部支撑凸台(m1、m2)，也即光口适配器的端口内部在位于第一线型支撑结构Z1的下方设置有第一底部支撑凸台m1，在位于第二线型支撑结构Z2的下方设置有第二底部支撑凸台m2；通过底部支撑凸台(m1、m2)对两个线型支撑结构(Z1、Z2)进行支撑。也即线型连接器挂钩H在上下方向(即端口底部 到顶部的方向)上，通过底部支撑凸台(m1、m2)和端口顶部的盖板实现限位。
应当理解的是，第一底部支撑凸台m1和第二底部支撑凸台m2的设置不应对CS连接器的光纤插芯01与光口适配器内部的光纤接口04的插拔造成限制。示意的，在一些可能实现的方式中，参考图2，可以设置第一底部支撑凸台m1和第二底部支撑凸台m2位于光纤接口04的上方，第一底部支撑凸台m1与第一侧面限位凸台n1固定连接，第二底部支撑凸台m2与第二侧面限位凸台n2固定连接。
此外，结合图1、图2、图4和图6所示，光口适配器的端口在底部对应解锁凸出部1的下方设置有连接器支撑轨道r，从而在CS连接器插入光口适配器的端口时，推拉舌片02沿该连接器支撑轨道r的上表面朝向光纤接口04一侧移动时，推拉舌片02前端上表面的倾斜坡面u卡入解锁凸出部1中；在沿该连接器支撑轨道r的上表面朝向远离光纤接口04一侧移动时，推拉舌片02前端上表面的倾斜坡面u整体抬升解锁凸出部1，并带动两侧的卡合凹陷部脱离卡合主体03上表面的凹槽s。
示意的，参考图2和图6所示，在光口适配器的端口中，沿第二方向YY’并列设置多个线型连接器挂钩H的情况下，相邻两个线型连接器挂钩H在第二方向YY’上靠近内侧的限位凸台可以为连接的一体结构。
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。
