Description

锁件体、解锁机构及光模块 技术领域
本发明涉及光模块技术领域，特别涉及一种锁件体、解锁机构及光模块。
背景技术
光收发一体化模块(简称光模块)的主要功能是实现光电/电光变换，通常由光电子器件、功能电路及光接口组成，是光纤通信系统的重要组成部分，根据封装形式的不同，主要有SFP、GBIC、XFP等。其中，SFP光模块为小型化可热插拔光模块，SFP光模块具有热插拔的特性，即在不关断电源的情况下光模块即可与设备连接或断开，由于SFP光模块在使用时通常会进行插拔动作，因此通常需要用一个模块自带的装置解锁脱扣，使光模块能够顺利地从系统主板上的笼子里脱出。
现有光模块的解锁机构，基于杠杆原理驱动锁头实现解锁，即，锁头位于杠杆的一端，杠杆的另一端与拉环连接，解锁时，以提升拉环的方式带的锁头向下运动，使得锁头脱离锁孔，采用这样的方式，解锁时需要将拉环提拉较大角度才能将杠杆旋转到位实现解锁，否则不但不能解锁，还容易造成锁头和笼子损坏。
发明内容
本发明的目的在于提供一种锁件体、解锁机构，以及应用该解锁机构的光模块。
为了实现上述发明目的，本发明实施例提供了以下技术方案：
一种锁件体，所述锁件体包括依次连接的锁头、锁体和锁尾，所述锁体设 置有转轴，所述锁件体可绕所述转轴转动，所述锁尾包括以滑动方式解锁的第一解锁部。
作为一种可实施方式，所述第一解锁部为具有斜面的斜面支脚。
根据本发明实施例，所述锁尾还包括以转动方式解锁的第二解锁部。作为一种可实施方式的举例，所述第二解锁部为平面板。
一种解锁机构，应用于光模块，所述解锁机构包括本发明任一实施方式提供的锁件体，所述锁件体安装于所述光模块的底座的第一腔体内，且可在所述第一腔体内绕所述转轴转动完成解锁动作。
作为一种可实施方式，所述解锁机构还包括拉环，所述拉环包括拉杆，所述拉杆包括臂部和/或突部，所述突部用于当拉杆在所述底座的滑动槽内转动时给所述第二解锁部竖直向上的顶力解锁，所述臂部用于当拉杆在所述底座的滑动槽内滑动时给所述第一解锁部竖直向上的顶力解锁。
一种光模块，包括底座及本发明任一实施方式提供的解锁机构。
本发明实施例提供的锁件体、解锁机构以及应用该解锁结构的光模块，可以实现单纯转动方式的解锁、单纯滑动方式的解锁、以及转动与滑动相结合方式的解锁，实现多种方式解锁；另外，结合方式解锁时，拉杆不需要转动较大角度即可解锁，解锁操作简单，用力小，且可以避免因解锁不便导致的锁头及笼子损坏。

解锁机构可以包括锁件体300、弹性件及拉环200。请参阅图图2、图3a、图3b，锁件体300包括依次连接的锁头302、锁体304和锁尾310。
作为一种可实施方式，如图3a所示，所述锁头302为钩状结构，锁头302的端部为斜面，所述锁头302可通过所述第一壳体600顶部的锁孔外凸于第一 壳体600的顶部。锁头302的端部设置为斜面，使得光模块10在插入笼子时，可通过斜面与笼子的边框挤压，下压锁头302，当光模块10完全插入笼子后，锁头302自动复位，将光模块10自动锁紧在笼子中。
作为进一步优选的可实施方式，锁头302的底部设有加强板301，加强板301可以增加锁头302的强度，延长其使用时间。
所述锁体304设置有转轴305，锁件体300通过转轴305与底座100连接，锁件体300可绕转轴305转动。为了增大锁件体300与底座100的接触面积，增强锁件体300与底座100连接的稳定性，锁体304的结构大于锁头302的结构，即锁体304的投影面积大于锁头302的投影面积，因此，锁头302与锁体304之间通过梯形结构的过渡部303连接。参阅图1a，底座100上设置有带螺孔的圆柱体(图中未标示)，锁体304上相应地设置有柱孔(图中未标示)，锁体304通过柱孔套设在圆柱体上。圆柱体与转轴305的配合使用可以进一步增强锁件体300与底座100连接的稳定性，锁件体300不会前后滑动，只会绕转轴305转动。
在本发明第一实施例中，所述锁尾310包括以滑动方式解锁的第一解锁部。
请参阅图2，作为第一实施例的一种可实施方式的举例，第一解锁部可以是具有斜面的斜面支脚308，本实施例中，第一解锁部为两个，即锁尾包括两个斜面支脚308，两个斜面支脚308可以直接与锁体304连接，也可以通过一连接杆连接；作为另一种可实施方式的举例，第一解锁部也可以是具有斜面的斜面板。
进一步优选地，斜面支脚308的端部设置有延长端307，锁定状态时延长端307平行底座100，也可以描述为锁定状态下延长端307平行于锁体304。一方面，延长端307可以增加锁头302与光模块10的底座100的着力点，增强锁件 体300与光模块10的连接稳定性；另一方面，还可以在紧急情况下给延长端307的底部施加竖直向上的顶力以实现解锁。
请参阅图4，本实施例中的拉环200包括拉杆，拉杆包括臂部20，用于当拉杆在滑动槽101内滑动时推动第一解锁部(本实施例中为斜面支脚308)，给第一解锁部竖直向上的顶力解锁。
请参阅图1a，图13a、图13b，作为进一步优选的可实施方式，光模块10还包括第二壳体400，第二壳体400的端部设置有豁口401，锁件体300的其中一个延长端307的底部与底座100设置有空隙，豁口401与空隙连通。
上述第一实施例中提供的光模块，可以实现以下两种方式的解锁。
解锁方式1：请参阅图7a、图7b，给拉环200施加外力，使拉杆的臂部20在滑动槽101内滑动，在滑动过程中，拉杆的臂部20与斜面支脚308接触，推动斜面支脚308，给斜面支脚308竖直向上的顶力(因锁件体300不能前后滑动，进而斜面支脚308不能前后滑动)，使得锁尾310竖直向上移动，相应地锁头302竖直向下移动，锁尾310上升到足够位置(滑动槽101足够长)后，锁头302与锁孔脱离，实现解锁。
解锁方式2：可参阅图13a，图13b，将工具(如图中所示的细棍)从豁口401伸入延长端307与底座100之间形成的空隙，利用工具的端部接触延长端307的底部，给延长端307施加竖直向上的顶力，将延长端307竖直向上顶起，进而使得锁尾310竖直向上移动，锁头302竖直向下移动，实现解锁。此种解锁方式可用于在紧急情况(例如拉环200不能正常使用)下解锁。
在本发明第二实施例中，锁尾310还包括以转动方式解锁的第二解锁部。
请参阅图3a、图3b，作为第二实施例的一种可实施方式的举例，第二解锁 部为平面板306。
作为一种可实施方式，斜面支脚308设置于平面板306的端部。当以拉杆转动的方式解锁时，拉杆(图中未标示)在转动过程中会给平面板306竖直向上的顶力，使得锁尾310竖直向上移动，基于杠杆原理，锁头302竖直向下移动，脱离锁孔，实现解锁。为了节省空间，如图3b所示，本实施例中，平面板306为凸字形结构。
作为进一步优选的可实施方式，平面板306设置有延长面板309，延长面板309与锁体304连接，延长面板309、斜面支脚308组成折弯结构，折弯结构可以增强锁尾310的强度，延长其使用寿命。制造时，锁尾310可以一体成型，以增强其强度。
如图9、图11-12所示，弹性件可优选用弹簧500，底座100上设置有用于安装弹簧500的腔体(图中未标示)，该腔体与第一腔体103连通，弹簧500设置于锁头302的下方，具体设置于加强板301的下方，用于维持锁件体300的锁定状态。
请参阅图5，本实施例中，拉杆包括臂部和突部202，突部202用于当拉杆在滑动槽101内转动时给第二解锁部(本实施例中为平面板306)竖直向上的顶力解锁，臂部用于当拉杆在滑动槽101内滑动时给第一解锁部竖直向上的顶力解锁。本实施例中，具体地可以是，臂部包括第一臂部201及第二臂部203，第一臂部201、突部202及第二臂部203依次连接，第一臂部201、第二臂部203用于当拉杆在滑动槽101内滑动时分别推动一个斜面支脚308，给斜面支脚308竖直向上的顶力以实现解锁。
作为一种更优的可实施方式，拉环200还包括匚形杆204，所述匚形杆204 的两端分别与所述第一臂部201、所述第二臂部203连接，第一臂部201、突部202、第二臂部203、匚形杆204组成环状结构。使拉杆转动或滑动时可通过握持匚形杆204实现，操作简便。
请参阅图8，进一步优选地，底座100的两侧分别设有凸台102，用于固定所述匚形杆204，避免光模块10处于锁定状态时匚形杆204前后摆动影响光模块10的使用。本实施例中，底座100的两侧均设有凸台102，当然地，也可以仅在底座的一侧设置凸台。
请参阅图10-图13b，本实施例提供的光模块10，可以实现四种方式的解锁：
解锁方式一：请参阅图8-11，给拉环200施加外力，使拉杆在滑动槽101内转动，在转动过程中，突部202竖直向上移动，给平面板306竖直向上的顶力，使得锁尾310竖直向上移动，相应地锁头302竖直向下移动，当拉环200转动至大约水平位置后，锁头302与锁孔脱离，实现解锁。
解锁方式二：请参阅图7a-7b，图12，给拉环200施加外力，使拉杆在滑动槽101内滑动，在滑动过程中，拉杆的第一臂部201、第二臂部203分别与两个斜面支脚308接触，推动斜面支脚308，给斜面支脚308竖直向上的顶力(因锁件体300不能前后滑动，进而斜面支脚308不能前后滑动)，使得锁尾310竖直向上移动，相应地锁头302竖直向下移动，锁尾310上升到足够位置(滑动槽101足够长)后，锁头302与锁孔脱离，实现解锁。
解锁方式三：转动拉环200，使得拉杆在滑动槽101内转动，突部202给平面板306竖直向上的顶力；拉动拉环200，使得拉杆在滑动槽101内滑动，拉杆给斜面支脚308竖直向上的顶力；在突部202与第一臂部201、第二臂部203的共同作用下，锁尾310竖直向上移动，锁头302竖直向下移动，实现解锁。此 种解锁方式下，拉杆不需要转动较大角度即可解锁，便于操作，可避免因施力不便(位置受限，难以转动较大角度)导致的解锁机构及笼子损坏。需要说明的是，此种解锁方式下，拉杆转动与滑动的执行操作没有顺序之分。
解锁方式四：请参阅图13a，图13b，将工具(如图中所示的细棍)从豁口401伸入延长端307与底座100之间形成的空隙，利用工具的端部接触延长端307的底部，给延长端307施加竖直向上的顶力，将延长端307竖直向上顶起，进而使得锁尾310竖直向上移动，锁头302竖直向下移动，实现解锁。此种解锁方式可用于在紧急情况(例如拉环200不能正常使用)下解锁。
在某些实施例中，底座100还设置有第二腔体104，用于安装光收发送组件，第一腔体103与第二腔体104相分隔。如图所示，拉环200需要置于光模块10的壳体外，如果第一腔体103与第二腔体104连通，那么存在于第二腔体104的电磁波可通过第一腔体103传播到光模块外，造成辐射污染。本实施例中通过将第一腔体103与第二腔体104相分隔，可以避免电磁波通过第一腔体103直接传播到光模块外，减小电磁辐射。
以上所述，仅为本发明的具体实施方式，但本发明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发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应所述以权利要求的保护范围为准。
