以下结合实施例对本发明作进一步的详细描述。
本发明所提供的机箱模块的具体实施例1：
如图3至图7所示，机箱模块包括机箱1以及安装在机箱1上的光模块8、PCB板5以及鼠笼4，鼠笼4套在光模块8的外部，鼠笼4焊接在PCB板5上，PCB板5通过螺钉固定在机箱1内的支柱上，通过鼠笼4与机箱1直接的接触实现对光模块8的屏蔽保护。
机箱1的结构如图4至图6所示，机箱1包括箱体101，箱体101上设有用来安装PCB板5的支柱，在箱体101的一侧一体成型有凸台9，凸台9凸出布置，凸台9内有插口10，插口10供外接的插头插入，插口10的内壁用来与插头外部的密封圈进行配合实现密封。在箱体101上还开设有开口朝上的U形槽14，U形槽14供鼠笼4自上向下放入，并且U形槽14的槽底、槽壁均用来与鼠笼4的外周面接触实现导电连通。其中，U形槽14与插口10连通，使得光模块8能够伸入插口10中，以用来与插头进行配合。
机箱1还包括屏蔽压板11，屏蔽压板11能够自上向下压装在U形槽14上，并与U形槽14接触，从而形成周向封闭的屏蔽腔，能够对鼠笼4实现全屏蔽。其中，屏蔽压板11分体可拆地安装在箱体101上，具体地，在U形槽14的槽口位置两侧开设有两个螺纹孔 13，屏蔽压板11上对应开设螺钉穿孔，使用时，通过两个压板紧固螺钉12将屏蔽压板11固定在U形槽14的槽口处。屏蔽压板11能够顶压在鼠笼4上，从而与鼠笼4实现导电连通，屏蔽压板11与U形槽14的槽口也实现导电接触，实现与鼠笼4的全屏蔽。在插口10与U形槽14之间的为隔板18。
本发明中，由于不需要另外加装插座来实现鼠笼与箱体之间的导电连通，结构简单，而且不需要为了安装插座而设置密封圈，从而导致屏蔽不连续，屏蔽效果差。本实施例中的机箱模块组装时，如图7所示，首先将鼠笼4套在光模块8上，将鼠笼4焊接在PCB板5上，然后将PCB板5自上向下安装在箱体101内的支柱上，并用螺钉进行固定。PCB板5向下安装的同时，鼠笼4放入U形槽14中并与U形槽14的槽底、槽壁接触，最后将屏蔽压板11装在箱体101上，此时鼠笼4自带的屏蔽片与屏蔽压板11连接，实现全屏蔽。
本发明机箱模块的具体实施例2：
如图8所示，与实施例1的不同之处在于，实施例1中，屏蔽压板通过两个压板紧固螺钉分体安装在箱体上。本实施例中，在箱体101上开设一个螺纹孔，屏蔽压板11的一端通过合页15与箱体101转动装配在一起，另一端通过压板紧固螺钉12进行固定。组装时，先将鼠笼4安装在PCB板上，将屏蔽压板11的一端抬起，放下PCB板，再将屏蔽压板11放下，用压板紧固螺钉12拧紧固定。其他实施例中，屏蔽压板的一端通过销轴转动安装在箱体上，另一端与箱体可拆相连，可拆相连的方式可以为螺钉连接，也可以为卡装，具体地，在屏蔽压板上设有卡块，在箱体上设置卡槽，实现卡装。
本发明机箱模块的具体实施例3：
如图9所示，与实施例2的不同之处在于，本实施例中，在箱体101上安装有销轴，销轴上安装有扭簧16，扭簧16一端顶在箱体101上，另一端连在屏蔽压板(图中未显示)上，通过扭簧16能够将屏蔽压板压在箱体101上，进而保证屏蔽压板能够压在鼠笼4上。
本发明机箱模块的具体实施例4：
与上述各实施例的不同之处在于，上述各实施例中，屏蔽腔均是由屏蔽压板和U形槽配合形成的。本实施例中，如图10所示，在机箱101上开设有贯通的通孔17，通孔17与插口连通，通孔17供鼠笼4插入，并且通孔17的内壁面用来与鼠笼4接触实现屏蔽导通。此时，通孔17构成了周向封闭的屏蔽腔。
本发明机箱模块的具体实施例5：
与实施例1-3的不同之处在于，实施例1-3中，屏蔽腔均为周向封闭的结构。本实施例中，将屏蔽压板取消，仅保留U形槽，供鼠笼自U形槽的槽口放入，此时虽然未能形成周向封 闭的屏蔽腔，但是鼠笼仍然可以与屏蔽腔的内壁面接触，从而实现屏蔽。
本发明机箱的具体实施例：
机箱的结构与上述机箱模块各实施例中机箱的结构一致，在此不再赘述。
最后需要说明的是，以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行不需付出创造性劳动的修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
