一种长手柄模块安装卸载装置
相关申请的交叉引用
本申请基于申请号为201910333114.0、申请日为2019年04月24日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及光通信技术领域，尤其涉及一种长手柄模块安装卸载装置。
背景技术
SFP、SFP+的国际多元协议中对拉环形式没有做明确规定，而SFP-DD的国际多元协议已明确展示长手柄拉环，说明长手柄拉环在小型封装光电模块中日趋成为主流应用。对比现在常用的转动式短拉环，长手柄拉环的应用范围更广，转动式短拉环一般应用在光口为插拔型的模块上，无法在AOC光缆模块上应用，因为拉环转动过程中会被光缆挡住，而无法完成模块卸载；长手柄拉环不但可以应用在光口为插拔型的模块上，还可以在AOC光缆模块上有很好的应用，因为直拉环的安装卸载装置在运动过程中始终处于光缆下方，与光缆互不干涉。
现有长手柄长拉环模块的安装卸载方式：拉环向后拉时，带动解锁件从模块壳体中斜向下运动，顶起屏蔽笼锁扣。该方式的缺点是模块壳体壁厚要求较厚，当遇到模块内光电器件体积较大时，模块金属壳体一方面为避让光电器件壁厚设置较薄，另一方面为了给解锁件腾出放置空间，只能在金属壳体较薄的壁厚上挖槽避让，势必会挖穿金属壳体，而金属壳体上设置通孔会严重影响模块的EMI性能。还有一种滑块水平向前推开屏蔽笼 锁扣的安装卸载方式，能克服前述不足，但与安装卸载相关的零件较多，组装过于复杂。
发明内容
本申请实施例通过提供一种长手柄模块安装卸载装置，解决了现有技术中模块直拉式装卸机构对壳体壁厚的要求较高，壳体设计避让结构影响EMI性能，装卸机构结构可靠性较差、适用范围较窄、安装较复杂的问题。

本发明实施例提供的一种长手柄模块安装卸载装置在锁定状态下时，所述第一拉簧310和所述第二拉簧320在所述壳体100中处于轻微的拉伸状态，使所述拉环200承受向右的拉力，所述拉环200的所述第三止位壁213和所述第四止位壁214分别顶在所述壳体100的所述第三挡面119和所述第四挡面120上；所述制动片400受到所述盖板500的所述压舌506的压力作用，所述第一加强筋405和所述第二加强筋406在所述水平面411 的底面与所述壳体100的第二腔体102底面贴合。

从图15和图16中可以看出，所述壳体100内的器件800体积较大时，会导致所述壳体100的壁厚T尺寸较小，本发明实施例占用所述壳体100的壁厚T较小，可保证所述壳体100的壁的封闭性和完整性，因此不影响模块EMI性能。
综上，本发明实施例采用的是制动片向下翘起将屏蔽笼锁扣撬开的方式卸载模块，模块金属壳体无需为滑块做避让结构，提供的是一种EMI效果更好、结构可靠性更高、组装更简便的长手柄模块的安装卸载机构。
