Description

可插拔模块的解锁结构与操作方法 技术领域
本发明涉及一种应用于通信用电子或光电子模块的解锁结构与操作方法。
背景技术
通信设备中向外部线路——如电缆、光缆，发送和从这些线路接收信号的端口，通常由可插拔的电子或光电子模块构成。这些模块以直接插入和拔出的方式被方便地随时安装和卸载于设备通信单元的安装插槽，或称安装笼中。其中模块插入的一端(称其为尾端)与通信设备内部的电子接口实现接触连接；模块的另一端(称其为前端)形成设备于面板上的通信端口，用于与具有对应标准化接头的各类电缆或者光缆连接，或者，模块所连接的线缆为一体化永久性质的连接，将模块拔除的同时线缆被一同移除。
对于可插拔模块于通信设备中的安装和卸载而言，一个核心的问题就是：既要保证模块在安装下的与设备间两者含密集连接点的电子接口间的稳定连接，防止模块在工作中因移位或意外被移除而导致信号受损或者线路中断，与此同时在此基础上模块又要能在需要的时候被方便地从设备中移除，这称为可插拔模块的锁定与解锁问题。
关于可插拔模块于通信设备中的锁定，其锁定的基本形式在业内会达成某种一致，并在有关的协议与标准中体现，以获得模块与设备间产品的匹配与通用。图1所示为业界及有关协议与标准中约定的针对其中一种主要类型的可插拔模块1'，其于设备安装笼2中锁定的基本形式。在该锁定形式中，安装笼2的两侧各设置一朝向安装笼2尾端并向笼内弯曲的弹片21，可插拔模块1'壳体两侧则各提供一某种形式的朝向该安装笼弹片21的锁止台阶面结构，如图1中所示例的锁止台阶面1711'。当模块1'插入安装笼2，模块的锁止台阶面1711'抵达安装笼弹片21位置时，弹片21向下释放抵住锁止台阶面1711'，从而形成模块1'于设备安装笼2中的锁定。该锁定位置同时对应着模块1'已插入到安装笼2的最里端，此时模块不能再向回移动或被拔出，实现模块与设备间电子接口的稳定连接。
上述约定的该锁定的基本形式，即决定了模块1'解锁的基本形式：为使模块1'自身能具备某种操作机制，使得在需要将模块移除时，该机制可将安装笼2两侧的上述弹片21顶起，使弹片21与模块1'壳体两侧的如图1所示例的锁止台阶面1711'分离，从而解除对模块的锁定，模块可于设备中拔出。业界该领域模块的已有解锁机制中，针对该类模块1'，大多利用到一具有设定斜面结构的可移动凸台结构，如图1中所示的解锁凸台1211'，其解锁操作机制使得模块1'上带有的该解锁凸台1211'在其解锁操作下可向弹片21方向移动，从而用其斜面结构将安装笼弹片21顶起，完成模块1'的解锁。
在上述的解锁基本形式下，业界运用到的已有解锁操作机制分为两种基本类型：一种是旋转式拉环设计，其拉环固定于模块壳体的前端并可绕该固定点旋转，该旋转通过连动结构带动壳体两侧的其末端为解锁凸台1211'的一解锁部件做水平前后移动，实现上述的解锁，以及复位操作，典型结构可参见代表专利US9146366B2；另一种是直拉式拉环设计，用一个水平向外拉动的拉环直接拉动模块壳体两侧的末端为解锁凸台1211'的其解锁部件向弹片21方向移动，在完成解锁的同时亦将模块拔出，之后再利用模块上配置的弹簧结构使解锁部件自行回位，即复位，典型结构可参见代表专利CN201310114326.2。
上述旋转式拉环在运用中的一个最大障碍问题是不能实现模块的带缆插拔：该方式在解锁模块前，需先行将模块所连接的线缆移除，否则拉环的该旋转解锁操作将因线缆的阻挡而不能进行。这对模块的插拔使用有着诸多不便，而对于为一体化永久连接性质的尾缆型模块而言，如有源光缆等，该方式则完全不能适用。直拉式拉环方式存在的一个不足之处则在于其对解锁状态的控制的缺乏：由于模块的解锁和拔出为同一向外拉动拉环的操作，因此无论是否真正需要将模块拔出，模块在解锁的同时其移位已经发生，信号随即已被中断。这种操作机制上的缺陷使得直拉式拉环方式在运用中有可能引发一定的误操作，如无意中扯动到拉环，或者解锁了错误线路的模块但已无法挽回，线路随即均已被中断等。与此同时，直拉式拉环方式也难以做到在位的复位，即在操作解锁动作之后，在模块尚未拔出的情况下将模块从解锁状态恢复至锁定状态，其间线路的工作不受到影响。直拉式方式这些问题的根本原因即在于该操作方式缺少对解锁状态及其步骤的相应控制。而对于旋转式方式而言，由于解锁前其需先将线缆移除，因此上述旋转式拉环方式天然不具备在位复位的功能。
发明内容
本发明提供一种可插拔模块的解锁结构与操作方法，首先在于解决现有旋转式拉环方式存在的不能带缆插拔的问题，而提供出一种新的可广泛适用的解锁与复位操作方法，同时，针对已有的直拉式拉环方式，可弥补其对解锁状态及步骤控制的不足，而完备模块的解锁与复位操作，在实现同样为简易操作的同时，将各种误操作的可能降至最低。

本发明的一项实施例如图2A、图2B所示。图2A为本发明的可插拔模块1XA的组装分解结构示意图，其组成部件包括：推拉手柄11A、解锁片12、壳体基座13、壳体盖板14、转动块15X、转动销101S、转动块工作弹簧102、解锁片回位弹簧103、模块电路板104、紧固螺钉105。除此外，模块壳体内部安装的其他各元件在该示意图中省略。图2B为图2A中各元素组装在一起后本发明的可插拔模块1XA的完整外观示意图，为处于其初始状态。需要说明的是，本说明中对涉及的各实施例结构中呈对称分布的一些相同或为镜像的部件或组成结构，在各示意图中均只对其中一个代表单元进行编号标注，对该编号的引用，除非另有前置说明，对其所指代的这些相同或为镜像的部件及组成结构不作特别区分。
其中，本发明的可插拔模块1XA的推拉手柄11A的详细结构如图3所示。其包括柄身连接端两内侧面各设置的转轴111，柄身连接端两侧面各设置的复位方孔112，和柄身连接端两内侧面各设置的限位柱113。限位柱113为一圆柱体。另外柄身末端呈45°特别弯折的部分为手触端114L，该特别弯折区域的设计使该手触端114L可同时适于推动和拉动手柄11A。图中柄身上显示的一块环状凹陷区域115此处为用于表示光电子类模块光波长工作参数的颜色标识区域，所用颜色标识为由相关标准中所约定。
本发明的可插拔模块1XA的解锁片12的详细结构如图4所示。其为一“H”形结构体，包括两个分别位于模块壳体两侧的呈纵向长条形结构的解锁臂121，和将两侧解锁臂121连接为一体的横向连接部122。解锁片12整体为片状结构，贴附安装于模块1XA的壳体表面，并可相对其壳体表面沿水平纵向前后滑动。其中，解锁臂121朝向模块1XA尾端的部分，即解锁臂121的末端，为解锁端，其包括解锁前沿1211， 该解锁前沿1211此处为一普通平板面结构边沿；解锁臂121朝向模块1XA前端的部分，即解锁臂121的前端，为连接和控制端，其包括转轴连接孔1212，复位让位方孔1213S，卡位方孔1214，半封闭旋转让位孔1215，和位于半封闭旋转让位孔1215上端边界与解锁臂121前端边沿交汇处设置的第一限位凸起1216。此外，解锁臂121前后端之间，即解锁臂121的中部，设置有沿水平纵向排列的弯折结构1217和解锁片回位弹簧安装方孔1218，其中弯折结构1217相对于回位弹簧安装方孔1218更靠向解锁臂121前端一侧。图5给出图4中半封闭旋转让位孔1215及其上端边界于上述边缘处设置的第一限位凸起1216的放大结构图。
这其中，解锁片12的转轴连接孔1212，用于与前述推拉手柄11A的转轴111连接。连接后，推拉手柄11A可相对解锁片12转动，并可推动和拉动解锁片做水平方向的运动。解锁片12的半封闭旋转让位孔1215，对应于推拉手柄11A的前述限位柱113。当推拉手柄11A与解锁片12通过推拉手柄11A的转轴111与解锁片12的转轴连接孔1212连接后，推拉手柄11A的该限位柱113，将位于解锁片12的半封闭旋转让位孔1215中。该半封闭旋转让位孔1215的设计，将允许推拉手柄11A经其限位柱113在该让位孔中的限制，做相对于解锁片12的由水平位置向上的转动，而不能向下转动，以图2B中所示模块1XA的工作方位而言。与此同时，半封闭旋转让位孔1215上端边界于上述边缘处所设置的第一限位凸起1216，将使推拉手柄11A在人为施力的向上转动下，其限位柱113克服和越过该第一限位凸起1216后，手柄不会自行回落至水平初始位置，而可停留于限位柱113越过该凸起之后的角度，此时可方便对模块进行插拔线缆等操作。
模块的壳体基座13及壳体盖板14为安装包括模块电路板104在内的模块各内部元件，和承载模块各机械作用结构与其他组成部件的主体。为方便说明，图6显示本发明的可插拔模块1XA的壳体基座13与壳体盖板14二者经紧固螺钉105连接后，形成的模块1XA的完整壳体表面的情况。该表面在模块壳体两侧的部分，具有配合解锁臂121解锁端与中部区域的第一组合凹槽空间171，和配合解锁臂121控制端的第二组合凹槽空间172。
其中，第一组合凹槽空间171通过对解锁臂121长条形结构的上下两个边沿的限制，使解锁臂121只能沿模块1XA壳体表面做水平前后方向(水平纵向)的运动。特别的，本发明的可插拔模块1XA壳体表面两侧的该第一组合凹槽空间171，在沿解锁臂121长条形结构的纵向长度上的上下两个边缘区域，设置有共面的上侧台阶面1713与下侧台阶面1714，其中上侧台阶面1713位于壳体基座13，下侧台阶面1714位于壳体盖板14。解锁臂121位于第一组合凹槽空间171中的部分，仅与该上侧台阶面1713与下侧台阶面1714相接触，以此可减小解锁臂121在本发明的模块的解锁与复位操作中，其与模块1XA壳体表面间的摩擦阻力。该上侧台阶面1713与下侧台阶面1714在模块壳体尾端一侧延伸的末端区域，另设置为微起的斜坡面，并在该微起斜坡面的最末端一小段有限区域内，连结为同一斜坡表面。同时，在该上侧台阶面1713与下侧台阶面1714微起斜面末端所在的凹槽边沿，形成该第一组合凹槽空间171中所 设置的模块1XA与安装笼弹片21相作用的锁止台阶面1711。该锁止台阶面1711同样由壳体基座13与壳体盖板14两部分共同形成，并于该锁止台阶面1711中部区域向模块尾端一侧凹陷形成一特定凹槽空间1712。与现有技术中的该凹槽空间为用于容纳解锁凸台1211'不同(参见图1)，本发明中设置的该凹槽空间1712，目的为减少安装笼弹片21与锁止台阶面1711间的有效作用宽度，使得相较于完整的安装笼弹片21的作用宽度而言，解锁臂121的解锁前沿1211能更易于将安装笼弹片21顶起，完成模块的解锁操作。
所述的上侧台阶面1713/下侧台阶面1714在模块壳体尾端一侧设置为微起斜面区域的设计，缘于业界相关协议与标准中对模块1XA壳体整体宽度尺寸的约定限制。在该约定下，解锁臂121的外表面不得高出于壳体基座13与壳体盖板14所组成的模块1XA的壳体表面(即，解锁臂121的外表面不能凸出于模块1XA的壳体表面之外)，除去在与安装笼弹片21相作用的壳体的锁止台阶面1711位置，允许其高出部分限值以下之外。由此，为保证解锁前沿1211充分实施解锁，即确保安装笼弹片21在被解锁前沿1211顶起时能与锁止台阶面1711彻底分离，即可在第一组合凹槽空间171配合解锁臂121解锁前沿1211解锁操作时所移动至的其末段有限区域范围内，设置一限定的该微起斜面，使解锁前沿1211抵达该锁止台阶面1711位置时，解锁前沿1211因受到微起斜面的抬升而使前沿的顶端此时能高出锁止台阶面1711的上沿表面(亦即壳体表面)，从而保证安装笼弹片21能完全移出锁止台阶面1711之外，保证二者分离和解锁效果的达成。
此外，在第一组合凹槽空间171中，还设置有允许解锁臂121上的弯折结构1217通过的垂向安装槽1715，和收纳该弯折结构1217与解锁片回位弹簧103的水平纵向收容槽1716，如图6中所示。本实施例中垂向安装槽1715与水平纵向收容槽1716均位于壳体基座13部分。其中，垂向安装槽1715一端开口于壳体基座13的底面，一端连通至水平纵向收容槽1716；水平纵向收容槽1716靠模块前端一侧的内壁面为设定的定位面1717，该定位面1717通过与解锁臂121的弯折结构1217相抵，决定解锁片12在模块1XA壳体上向前端方向可移动至的终极位置。
本发明中的第二组合凹槽空间172主要包含两个设置区域，一个是提供转动块15X运动空间的转动块安装槽1721，另一个是经限位柱113在其中的限制下控制推拉手柄11A运动轨迹的手柄限位槽1722。本实施例中，第二组合凹槽空间172均由壳体基座13形成。其中，转动块安装槽1721中提供有一垂向转动销安装轴孔1723S，用于安插转动销101S。转动销安装轴孔1723S为非通孔性质，其底端为封闭，转动销101S则为一相对较短圆柱体，其与转动销安装轴孔1723S间设置为紧配合，因此当转动销101S安插于转动销安装轴孔1723S中时，转动销101S不会在工作中脱落掉出。转动块安装槽1721中另设有一水平横向收容孔1724，用于收纳转动块工作弹簧102。手柄限位槽1722的设置情况，将结合推拉手柄11A的运动和操作方式在后文中具体说明。这其中，特别的，手柄限位槽1722的上沿边界某处，对应推拉手柄11A处于其初始水平状态的其限位柱113的位置(参见图13A)，设置有第二限位凸起1725， 其局部放大结构图如图7所示。手柄限位槽1722中设置的该第二限位凸起1725，使本发明中的推拉手柄11A在其初始位置，比如模块为安装于设备安装笼中，处于锁定的其正常工作状态下，手柄能保持一种稳定，不会因外界的振动等环境因素而导致手柄发生跳动或者颤动，而产生出噪声的影响。
本发明中的转动块15X是决定本发明解锁工作机制与相关定量参数设计的关键部件。该转动块的一种基本结构形式为图8的代表性结构15'所示，其可描述为一“共轴并联”连体转动结构。作为一个示例，该代表性共轴并联连体转动结构15'包含一个作用部151'和一个去作用部152'，作用部151'与去作用部152'绕共同的旋转轴101'转动，且两者间连结为一互作用的整体，在任一时刻，其中一方转动或者旋转至某一角度，另一方亦随之转动或转至同样的角度；与此同时，作用部151'与去作用部152'在空间上沿旋转轴101'的轴向方向相隔有一定距离y，根据应用，y的取值应保证作用部151'与去作用部152'各自的与其自身相作用的第三方作用对象之间不发生结构上的干涉或者冲突。即，作用部151'与去作用部152'以轴向分离的方式绕同一旋转轴101'转动，同时二者间形成一互作用的整体，并与其各自作用对象之间发生结构上的作用关系。以x1、x2分别表示作用部151'与去作用部152'的其作用点距离旋转轴101'轴心的径向位置距离，可知，作用部151'与去作用部152'上的其作用点绕旋转轴101'转动的旋转位移幅度之比，等于其各自距离该旋转轴101'轴心的径向距离之比，即x1/x2。作为一般情形，作用部151'与去作用部152'可以位于旋转轴101'的同侧，也可以分别位于对侧。本发明中的该共轴并联连体转动结构15'的一个特性即在于：该比值x1/x2(在带符号下)可以取值为+1，即两者作用点的有效位移幅度与方向完全相同，也可以取值为+1以外的任一所需值。此外，在一般性原理下，该共轴并联连体转动结构可同时包含多个作用部和/或者去作用部，在任一作用部与其对应去作用部之间均形成以上的有关对应关系。
该共轴并联连体转动结构15'于本实施例中的具体实施结构为图9所示的转动块15X。该转动块15X包含一个卡位凸起151和一个复位凸起152，分别对应上述共轴并联连体转动结构15'的作用部151'与去作用部152'，二者位于转动轴的同侧；转动块15X为绕固定于可插拔模块1XA第二组合凹槽空间172中的垂向转动销101S转动，转动块15X上设有旋转轴孔153X，用于与转动销101S连接。此外，转动块15X的背面为转动块弹簧作用面，可由简单平面结构构成。图10A显示转动块15X经与转动销101S连接安装于模块壳体的转动块安装槽1721中的情形。另一种较佳的情形是在转动块安装槽1721中使用通孔性质的转动销安装轴孔1723L(参见图6)，然后使用一相对较长的转动销101L，其与该转动销安装轴孔1723L间仍为紧配合，图10B显示此情形下的转动块15X于模块壳体的转动块安装槽1721中的安装情形。可知该情形下，转动销101L于转动销安装轴孔1723L中安装后，转动销101L的底端可由转动块安装槽1721的内壁面相抵，因此转动销101L也不会在工作中脱落掉出。图10B的使用通孔1723L与长转动销101L的结构，与图10A使用非通孔1723S与短转动销101S的结构相比，其好处可在于，一旦发生转动销于安装轴孔中断裂损坏的情况，图10B的情 形将有利于将残余销体从轴孔中去除，可方便此情况下的返修。
上述图9所示的转动块15X结构中，卡位凸起151用于与解锁片12控制端的卡位方孔1214相作用(参见图4)，复位凸起152用于与推拉手柄11A的复位方孔112相作用(参见图3)。其中，卡位方孔1214与卡位凸起151具体相作用的为卡位方孔1214所提供的相应孔结构边沿，称为卡位边沿；复位方孔112与复位凸起152具体相作用的为复位方孔112所提供的相应孔结构边沿，称为复位边沿。本实施例中，解锁片12的控制端，对应所连接手柄11A处于其水平位置时的手柄复位方孔112的位置，设置有一复位让位方孔1213S(参见图4)，该复位让位方孔1213S使转动块15X的复位凸起152经其让位后，可与推拉手柄11A的复位方孔112的复位边沿作用。上述有关的具体作用方式如下：
图11显示本实施例中的该转动块15X与推拉手柄11A、解锁片12一起完成于可插拔模块1XA上的装配后，在模块解锁位置下三者间的相互位置关系。其中，转动块15X背面设有转动块工作弹簧102，其安置于复位凸起152正下方，并收纳于转动块安装槽1721中的水平横向收容孔1724中(参见图6)。推拉手柄11A以其转轴111经解锁片转轴连接孔1212连接至解锁片12，当其水平推动解锁片12至模块解锁位置，即解锁臂121上的解锁前沿1211抵达模块壳体两侧的锁止台阶面1711时(可参见图13B)，位于解锁臂121控制端的卡位方孔1214，和位于解锁臂121控制端的复位让位方孔1213S随同推拉手柄11A的复位方孔112，将同时分别抵达至转动块15X的卡位凸起151和复位凸起152的正上方。此时，在转动块工作弹簧102的作用下，转动块15X的卡位凸起151和复位凸起152将同时向上弹起进入到各自对应的上述方孔中。这其中，卡位凸起151通过解锁臂121的卡位方孔1214(其卡位边沿)将解锁片12卡住，使解锁片12不能在其回位弹簧103的作用下自行回退，而使本发明的可插拔模块1XA保持于该解锁状态。卡位凸起151作用于卡位方孔1214卡位边沿的有效作用面为垂直面，以实施对解锁片12的有效卡位。此时，若可插拔模块1XA为安装于设备安装笼2中，在安装笼弹片21已被解锁片前沿1211顶起的该解锁状态下，反方向水平拉动推拉手柄11A，即可将模块1XA从安装笼2中拔出。可知，在模块解锁和拔出的该操作中，可插拔模块1XA所连接的线缆不需要被移除。
可插拔模块1XA于安装笼2中拔出后，接下来即需要进行模块的复位操作，即使解锁片12回位，使解锁前沿1211离开模块壳体的锁止台阶面1711，回复至初始位置，以备下次模块插入设备安装笼中时的锁定。此时，可将推拉手柄11A向上旋转抬起，推拉手柄11A的复位方孔112(其复位边沿)此时将与转动块15X的复位凸起152作用，随着手柄转动的进行，复位方孔112的复位边沿将逐渐使复位凸起152下压，这其中，复位凸起152与手柄复位方孔112的复位边沿相作用的面为一设定的斜坡面(参见图9)。与此同时，与复位凸起152并联连体转动的卡位凸起151也将随之一同下退，直至脱离与解锁片卡位方孔1214的作用。至此，转动块15X对解锁片12的卡位作用解除，解锁片12将在其回位弹簧103的作用力下自行回退至初始位置，模块的复位操作完成。可知，在本发明的可插拔模块1XA的该复位操作中，也不需要 将模块1XA所连接的线缆移除。
更进一步的，可知上述复位操作也可在可插拔模块1XA未从安装笼2中拔除的状态下进行，其复位操作完全相同，只是在设备面板存在有垂向较近间距邻近端口的情况下，如图12中情形所示，需保证推拉手柄11A的该复位操作旋转角度，不会使手柄触碰到上端相邻模块或其所连接线缆3的有关部位，或者，不应因上述因素而导致该在位的复位操作不能进行。为此，通过设定有关的结构参数，其中尤其比如调整转动块15X卡位凸起151的作用面距离转动销101S轴心的距离x1，结合包括所确定的转动块15X复位凸起152的作用面距离转动销101S轴心的距离x2在内，可使推拉手柄11A在一所需的限定转角下完成该模块的复位操作。如本发明针对图12所示的业界一种标准叠加笼端口的实施例情形，对于推拉手柄11A设计长度约为6厘米的所示情形，该在位复位所需的旋转角度被设定于5.75°，其可实施的最大旋转角度则被限定为7.25°，在该角度之上旋转动作将不能进行(参见图13C)，可满足上述相关的要求。当手柄11A长度减小时，上述复位操作的各旋转角度设计值则可相应增大。
通过以上使用推拉手柄11A的解锁与复位操作可知，与现有直拉式拉环方式的操作相比，由于本发明模块解锁操作的手柄移动方向，与向外拔出模块的手柄移动方向相反，为向里推动，因此，与直拉式方式解锁与拔出模块为同一向外拉动拉环的操作相比，本发明的可插拔模块1XA不会发生在使用中因意外被拔出而导致信号意外中断的情况，因这种直接向外拉动本发明的可插拔模块1XA手柄的操作，不会使其解锁，也就不会将其拔出。同时，向上碰触到手柄使手柄发生旋转抬起也不会使模块解锁。除此外，即使误触碰到手柄使其发生向里的推动并直至解锁，或者，在本发明的模块的在位使用中，对其进行了错误解锁，即解锁了错误线路的模块，只要模块尚未操作拨出，均可对其进行随即的纠正，即可对模块实施在位的复位，恢复其锁定状态，过程中线路信号均保持不受影响。以上这些优势均是直拉式拉环方式，以及旋转式拉环方式所不能具备的。对于旋转式拉环方式而言，由于其无论解锁还是复位，都需先行将线缆移除，因此无论何种情形，包括正常解锁与误操作，其信号被中断都无可避免。
综上可知，本发明的可插拔模块的解锁结构及操作方法，为模块的解锁与复位提供了一种完备的操作机制，并可在最大程度上避免误操作和意外的发生，而同时其相关的各项操作亦简单易行。
根据上述推拉手柄11A的解锁与复位操作，即可对本发明中的可插拔模块1XA的手柄限位槽1722的设置情况进行说明。如图6、图7所示，该手柄限位槽1722由上下两个限位边界面形成，其对推拉手柄11A的限位柱113实施限位作用。其中，手柄限位槽1722的下边界面为一水平直面，它使推拉手柄11A在推动解锁片12向模块尾端移动，进行解锁操作时，手柄限位柱113可以选择以该水平直面相抵，同时在槽的部分上边界面的共同约束下，使手柄11A基本控制为水平方向的平移运动，直至达到解锁位置。图13A显示在推拉手柄11A的初始水平状态，其限位柱113于手柄限位槽1722中的位置。这其中，限位柱113与前述的设置于手柄限位槽1722上边界面 的第二限位凸起1725相抵，在无专门外力作用下，手柄11A不会发生向上的转动或者跳动。手柄限位槽1722的上边界面则为曲面与水平直面相结合的组合面，其靠里一段区域呈向上凹陷，其最外侧，即靠向模块端口的一侧，为一圆弧形让位曲面，在其他不需要手柄11A发生旋转而保持水平状态的区域则为水平直面。这其中，手柄限位槽1722上边界面最外侧的圆弧形让位曲面，允许推拉手柄11A经其限位柱113由其所处水平初始位置向上做转动。其中，解锁片12控制端的半封闭旋转让位孔1215，始终对推拉手柄11A经其限位柱113的相对解锁片12的向上转动进行让位，以下各情形中该基本让位均相同。
图13B显示推拉手柄11A向里，即向模块尾端，水平推动至模块解锁位置时，其限位柱113于手柄限位槽1722中的位置。在该位置，解锁片12被转动块15X的卡位凸起151通过解锁臂121上的卡位方孔1214卡住，模块1XA保持在该解锁状态。在该状态下，手柄限位槽1722的上边界面将允许限位柱113由此处做向上的转动。
图13C显示推拉手柄11A由该解锁位置向上旋转，进行模块的复位操作，在确保解锁片卡位方孔1214脱离转动块15X卡位凸起151的卡位时，其限位柱113于手柄限位槽1722中的位置。可知，对于所设定的推拉手柄11A的最大允许复位操作旋转角度，手柄限位槽1722的上边界面此处设置为：当限位柱113旋转至该角度时，该旋转将被上边界所终止，并在之后的解锁片12的回位过程中均驱使限位柱113保持在该最大旋转角度以下。
在图13C所示的该复位操作的最大旋转角度下，解锁片12已脱离转动块15X卡位凸起151的卡位，此时在解锁片回位弹簧103的作用下，解锁片12将开始自行回位，同时手柄限位槽1722的上边界面将通过对手柄限位柱113的约束，驱使手柄11A回复至图13A或图13D所示的水平初始状态。与此同时，解锁臂121上的弯折结构1217将抵达模块壳体两侧第一组合凹槽空间171中的前述定位面1717，代表解锁片回位过程结束，此时限位柱113将返回至手柄限位槽1722中的第二限位凸起1725位置。
此外，图13E显示从推拉手柄11A的水平初始位置，向上旋转手柄，使手柄限位柱113依次克服和越过第二限位凸起1725、第一限位凸起1216后，手柄停留于越过第一限位凸起1216后的情形。该状态被设置为：在本发明的可插拔模块1XA的初始状态，可将推拉手柄11A向上旋转抬起，而使其自行保持于刚越过第一限位凸起1216之后的角度，以方便此时需要时对模块进行插拔线缆等操作。解除这种旋转抬起状态，使手柄11A回复至水平位置，只需向下压动手柄，使限位柱113依次向回克服两个限位凸起即可。此外，根据该实施例结构可知，推拉手柄11A在越过第一限位凸起1216之后，还可继续向上旋转直至向模块尾端完全翻起，至手柄的有关部位碰触到模块壳体的相应部位而止。这种手柄可以完全向后翻起的状态，虽不属本发明的目的，也非本发明可插拔模块1XA其工作和使用中的标准操作内容，但其有关的运用，仍可为一些特别的情形提供出某种操作上的便利，例如，在显微镜下对光电子模块的端口进行某种表面状况的检查时，以及，其可为可插拔模块1XA的组装过程提供有关的便利，后者的有关描述可见下文关于模块组装过程的说明。与此同时，为防止这种未受 限制的，尤其是不经意之下防止已越过第一限位凸起1216之后的推拉手柄11A因模块姿态原因而发生突然地向后翻起，造成对手柄和模块壳体相应部位的可能损伤，对所述实施例下的该推拉手柄11A向后翻起时其会与模块壳体发生接触的手柄部位116，参见图3中所示，可做表面圆滑的预防性处理。
在上述的实施例中，可知，在可插拔模块1XA的复位过程中，解锁片12脱离转动块15X卡位凸起151的卡位，在回位弹簧103的作用下进行自行回位时，存在解锁片的片体自身，自其复位让位方孔1213S一侧边沿开始的对转动块15X复位凸起152的接续下压(参见图13C至图13D过程)；同时，在推动手柄11A从其初始位置至模块解锁位置时，即包含有该解锁片片体自身对转动块15X的这种额外下压(参见图13A至图13B过程)。转动块15X的这部分受压向下转动，对模块的解锁与复位而言无关联效用，也与推拉手柄11A的旋转操作无关，而仅缘于解锁片12自身片体在移动过程中对复位凸起152的接触而引起的额外下压。转动块15X的这部分额外下压转动，本质上为一种无效用的空转，虽然并不影响本发明模块解锁和复位操作的一般性原理的进行，但对于特定应用场合而言，其可能造成实际可用的转动块15X无法实现，因该额外的下压转动，需要模块壳体为此提供额外并且可能为可观的凹槽横向深度上的允许空间，这对于空间尺度上十分有限的模块类型而言，将成为设计上的阻碍问题。
为此，本发明的另一个实施例为可插拔模块1XA+，其与前述可插拔模块1XA的不同之处在于，其对解锁片的影响片体部分做了改动，将原复位让位方孔1213S(参见图4)拉长为矩形长孔1213L，如图14改动后的解锁片12+所示。将原复位让位方孔1213S改为特定长孔1213L后，在操作推拉手柄11A进行解锁和复位操作时，解锁片上的该让位长孔1213L将在解锁片前后运动的全程中都对转动块15X的复位凸起152进行让位，而不仅在解锁和该对应的待复位位置下。亦即，特定让位长孔1213L的设计，可将解锁片对转动块15X的额外下压效应完全消除，因此可省下原额外下压转动会对模块壳体空间所带来的消耗。图15A、图15B单独显示出该改动后的解锁片12+于模块壳体上分别处于初始和解锁位置时的情形，可清楚地反映出模块从初始到解锁再到回位的整个过程中，该让位长孔1213L对转动块15X的让位作用。
更进一步的，还可在上述让位长孔1213L的基础上，采用图16所示复合让位孔1213P的设计，其包含一与原让位长孔并行排列，作为辅助控制孔的短孔区域；与此同时，在转动块15X复位凸起152的一侧添加一辅助控制凸起152P，如图17的转动块15Xp结构所示。这其中，复位凸起152与图16所示解锁片12P的复合让位孔1213P的下端长孔区域配合，该长孔区域即相当于前述可插拔模块1XA+中让位长孔1213L对复位凸起152的全程让位作用；辅助控制凸起152P则与图16所示解锁片12P的复合让位孔1213P的上端短孔区域配合，该短孔区域即相当于原有可插拔模块1XA中原复位让位方孔1213S对转动块15X复位凸起152的有限让位作用。由于辅助控制凸起152P不承担复位功能，而独立于复位凸起152，因此其高度可单独设计，藉此可实现在某一范围内，在该实施例的模块解锁与复位过程中，任一所需的解锁片12P对转动 块15Xp的某一指定程度下压。这种在一定范围内可任意设置的指定程度下压对某些场合而言是有利或者需要的，比如可以缓解此时某些设计下的推拉手柄11A从初始到解锁位置的运动过程中，手柄的外廓边沿与露出的转动块复位凸起152间的接触冲击。图18A-C依次显示出该实施例下对应的可插拔模块1XpA分别处于初始、中间和解锁位置时解锁片12P与转动块15Xp间的代表性关系示意图，可显示出解锁片复合让位孔1213P与转动块复位凸起152与辅助控制凸起152P这一复合结构共同实施下的效果。
以以上实施例中的可插拔模块1XA为代表，参见前述有关附图，本发明的上述可插拔模块的有关组装过程及各部件的装配情况如下：
第1步：将推拉手柄11A经其转轴111与解锁片12的转轴连接孔1212连接，完成推拉手柄11A与解锁片12之间的装配。其中，完成装配后，推拉手柄11A的限位柱113落于解锁片12的半封闭旋转让位孔1215中。
第2步：将转动销101S(101L)安装于壳体基座13侧面的第二组合凹槽空间172中的转动销安装轴孔1723S(1723L)中，该转动销于转动销安装轴孔的安装为紧配安装，安装后转动销101S(101L)的部分销体为露出于转动销安装轴孔1723S(1723L)上端。然后，将转动块15X以旋起90°的角度，经其旋转轴孔153X套接于转动销101S(101L)露出于转动销安装轴孔1723S(1723L)上端的销体上，套接到位后将转动块15X旋下至转动块安装槽1721内，完成转动块15X于壳体基座13上的初步安装。该安装后的转动块15X可绕转动销101S(101L)往复转动。
第3步：将两侧已初步安装的转动块15X分别旋起至一定角度，将转动块工作弹簧102分别塞入其各自位于转动块15X下的转动块安装槽1721中的水平横向收容孔1724中，然后以手指或者简单工具同时压下两侧的转动块15X，以压住转动块工作弹簧102。之后，将解锁片12两侧的弯折结构1217通过壳体基座13侧面第一组合凹槽空间171中的垂向安装槽1715，由上至下置于该垂向安装槽1715中，此时解锁片12为套接于壳体基座13之上，待完全装入。特别的，在此过程中，可事先将已与解锁片12装配的推拉手柄11A朝解锁片12尾端方向完全掀起，以暂时省去手柄限位柱113于壳体基座13前端手柄限位槽1722中的定位安装。接着，继续向下装入解锁片12，当解锁臂121开始触碰到压住转动块15X的手指或者工具时，逐步松开手指或工具，使解锁臂在下移过程中逐步取代手指或工具而保持持续压住转动块15X，直至解锁臂121完全落入壳体基座13两侧的第一组合凹槽空间171中，至此完成解锁片12于壳体基座13上的安装。解锁片12安装到位后，其弯折结构1217将位于壳体基座两侧第一组合凹槽空间171中的水平纵向收容槽1716内，此时可将解锁片12朝模块前端方向滑动至其最前位置，然后将之前为向后翻起的推拉手柄11A向回翻回并压下至水平位置，此时手柄限位柱113将进入至模块壳体前端的手柄限位槽1722中，推拉手柄11A此时将可带动解锁片12在水平方向上往复滑动。
第4步：将解锁片回位弹簧103经解锁臂121上的回位弹簧安装方孔1218塞入壳体基座13两侧的上述水平纵向收容槽1716中，弹簧的一端与解锁片弯折结构 1217相抵，另一端与水平纵向收容槽1716靠模块尾端一侧的内壁相抵。此时，解锁片12受到该回位弹簧103的作用力，将自行滑动至其弯折结构1217与壳体水平纵向收容槽1716靠模块前端一侧的内壁，即前述的定位面1717相抵。至此，可插拔模块1XA壳体上的各主要部件于壳体基座13上的装配完毕。
第5步：完成壳体基座13内部包括模块电路板104在内的各元件的安装。
第6步：最后，将壳体盖板14与壳体基座13连接，经紧固螺钉105固定，可插拔模块1XA的组装完成。
由以上装配过程及内容可知，使用本发明解锁结构的上述可插拔模块，其组装过程简单快速，装配牢靠稳固，无隐患，也无需借助特殊或专门工具，具有很好的可操作实施性。与此同时，其部件的拆卸与更换也十分容易，如上述实施例中的关键部件转动块15X/Xp，其于转动销101S/L上的拆卸和更换实质为一种快拆方式，其操作可十分快速地完成，其中，转动销101S/L自身在不损坏下可为永久安装件，无需拆卸。
除以上实施例中的转动块15X结构外，本发明中的共轴并联连体转动结构15'还可采用如图19中所示的转动块结构形式，包含双边连接的转动块15Y和另一种单边连接的转动块15Z。前述实施例中的转动块15X为一种单边连接的形式，根据不同模块实施例结构或者要求，可分别考虑采用前述实施例的单边连接转动块15X，和图19中所示的单边连接转动块15Z。双边连接转动块15Y可用于进一步强化或者提升转动块的某些性能，如操作精度、强度可靠性等。该双边连接转动块15Y于本发明对应可插拔模块1Y(其完整示意图略)的壳体上的装配示意如图20所示，其中，为配合转动块15Y卡位凸起151与复位凸起152两边同时与所示转动销101L+的连接，考虑加工工艺上的有关限制，需从壳体基座13与盖板14相接的一侧打孔，以形成所示的上下为贯通的转动销安装轴孔1723L+。当盖板14与基座13安装在一起后，盖板14将封堵住转动销安装轴孔1723L+的下端开口，转动销101L+与转动销安装轴孔1723L+之间仍为紧配合，因此该结构下的转动销101L+也不会发生在使用中的脱落掉出。此外，与前述的有关实施例情形相同，特定场合下，图19所示的双边连接转动块15Y与单边连接转动块15Z也可使用到附加辅助控制凸起152P的结构。
在本发明的其他实施例下，根据所应用设备的面板端口排列情况，包括其排列方向，以及所连接线缆在使用环境中的有关布线方面的考虑或者需要，推拉手柄11A的柄身基本形状还可采用如图21A-C分别所示的可插拔模块1A+、1B、1C的推拉环11A+、11B、11C的形式，其中，模块1A+仍为相对长柄情形，模块1B、1C为短柄设计。在这三者实施例中，对前述实施例中的推拉手柄11A柄身末端呈45°特别弯折的手触端114L部分，对其弯折部分的长度均做了缩减，成为仅考虑适合推动目的的推拉环末端114S，与此同时在柄身末端增设一中空的环状结构117，或者在图21C所示的某最短柄身设计下，直接使用柄身与解锁片连接端处的“U”型中空环状结构118，作为对拉动推拉环操作的辅助。这其中，对于图21B、图21C所示的短柄身设计，其复位操作的旋转角度相比之前长柄身情形可以和需要一定程度的增加，为此可调整比如 减小模块1B/C中所配置的转动块15X/Y/Z(图中不可见)的卡位凸起151距其转动销轴心的位置距离，即前述的x1值(参见图8)，同时对应调整解锁片12B/C上的卡位方孔1214的位置。其中卡位方孔1214经此调整后的情形可由图21B、图21C中示意。
基于本发明的可插拔模块的解锁等操作为推拉式方式，本发明的可插拔模块的推拉手柄或者推拉环，整体为采用比如金属材料制作，如轻质的铝合金材料。
图22给出本发明中的转动块部件的另一种基本结构形式，其为卡位与复位凸起二者垂直迭加的转动块15V。该垂直迭加转动块15V将卡位与复位凸起合并为同一凸起，在沿凸起的垂直高度方向，将凸起的轮廓表面划分为上、下两个作用区段，其中下段为卡位区段151V，上段为复位区段152V，其各自分别具备前述实施例中的转动块卡位凸起151和复位凸起152的作用面特征。与前述的可称为“轴向分离”形式的“共轴并联”连体转动结构相比，该垂直迭加结构可称为“垂向分离”的“共轴迭加”连体转动结构。
图23显示在该垂直迭加转动块15V结构下，其对应的可插拔模块1VA中与之配合的推拉手柄16A、解锁片12V，与该转动块15V三者间的分解结构示意图。图24显示在模块解锁位置，三者结构于模块1VA上装配下的相互间位置关系。这其中，推拉手柄16A、解锁片12V的大部分结构与前述的有关实施例相同，具体参见图3、图4所示，其不同之处在于：原推拉手柄11A的复位方孔112此处成为一个复合结构，其包括矩形复位孔162——其包含复位边沿，和与该矩形复位孔162(及其复位边沿)相接，形成于手柄内侧面的一卡位让位凹槽169，该部位的放大结构图如图25所示；原解锁片12的卡位方孔1214和复位让位方孔1213S，此处合并为同一矩形复合卡位孔1214V，该复合卡位孔1214V既提供卡位边沿与转动块15V的卡位区段151V相作用，用于解锁片12V的卡位，同时又对迭加于卡位区段151V之上的转动块15V的复位区段152V施行让位。
图26显示该转动块15V装配于可插拔模块1VA壳体上的情形。图27A给出在模块的解锁位置，上述三者结构装配于可插拔模块1VA壳体上的相互间作用情况的剖面示意图。从图27A中可清楚地看到，手柄16A上的与其矩形复位孔162相配接的卡位让位凹槽169，其作用是为转动块15V卡位区段151V的顶部让位，使转动块15V的卡位区段151V能部分露出于解锁片12V的复合卡位孔1214V，以实施充分的卡位作用。图27B给出在该解锁位置下，推拉手柄16A进行复位旋转操作，当旋转至所设定的最大允许复位操作旋转角度时，上述三者结构于可插拔模块1VA壳体上的相互间作用情况的剖面示意图(注：仅为原理性示意，实际工况应更优于图中所示情形)。其中，所设定的最大允许复位操作旋转角度，与前述实施例中源自业界标准叠加笼安装情形下的依据相同(参见图12)，为7.25°。从图27B中可清楚地看到，当手柄16V旋转至该角度时，解锁片12V已经脱离了转动块15V卡位区段151V的卡位，可开始自行回位。
从该实施例的上述结构示意图中可知，在垂直迭加转动块15V方案下，因复位与卡位凸起迭加为合一，因此该实施例下的解锁片12V从原理上不能提供在模块解 锁与复位操作的全程中对转动块15V复位区段152V的让位设计。因此，在该实施例下，存在转动块15V来自于解锁片自身片体作用的额外下压，而对模块壳体的横向容纳空间有额外的需求和消耗，参见图27C所示解锁片12V在其回位过程中其自身片体部分对转动块15V的额外下压的剖面示意图。该垂直迭加方案的优点则在于结构紧凑，其转动销101V的受力结构简单，因此可获得较好的稳定和强度可靠性。
此外，在本发明的上述实施例中，所述转动块以绕某固定轴转动而实现上下起伏的作用形式，在某些应用和场合下，也可等效和替代为比如直接上下平移的运动和结构，因此可提供该类作用形式的一般意义上的运动块结构，均属于本发明所主张的权利范围。
