Description

一种模块结构 技术领域
本发明属于光通信领域中光电模块领域，尤其涉及一种模块结构。
背景技术
为了能在有限的空间内传输更多的数据，小型可插拔模块在光通系统设备中的使用密度越来越高，这就对成本越来越低的模块提出越来越高的可靠性要求，从模块机械结构的角度考虑，安装卸载装置是核心。
目前模块的安装卸载方式可以采用滑块向前推开或翘起屏蔽笼锁扣，如图1所示为本发明提供的一种现有技术模块结构的爆炸图，如图1中所示，电路板430置于底座600内，外罩100置于电路板430上方侧面与底座600相连，底座的一端还设置有制动片700和拉环800，以及将制动片700和拉环800与底座600固定的定位盖300，底座600的上底面上还设置有锁扣。该模块结构插入系统设备的金属屏蔽笼时，底座上的锁扣顶起金属屏蔽笼的簧片进入簧片上的卡孔中，此时模块结构安装在系统设备的金属屏蔽笼中；使该模块结构从系统设备上卸载时，拉动拉环800，该拉环800转动带动制动片700向金属屏蔽笼的簧片移动，制动片700将簧片上的卡孔顶出底座600上的锁扣，此时用手继续拉手环600将模块结构沿金属屏蔽笼反方向拔出，即可完成卸载。
现有技术的模块结构的缺陷包括：
1、拉环600拉出使模块结构从系统设备上卸载完成后，该拉环600不能自动复位，对使用带来不便，而其他带有自动复位功能的专利技术中制动片必须采用压铸件才能实现，加工工艺复杂，并且长期摩擦后镀层破损，从而影响自动复位功能。
2、模块结构对电路板430进行固定时，使用弹性冲压件从侧面压电路板430，使电路板430固定在底座600上，但是压电路板430的弹性结构处都有开口，电磁屏蔽效果较差。
3、模块结构的外罩100的侧面上设置有通孔，而底座600的侧面的对应位置设有凸起，在封盖过程中外罩100从底座600的上方向下套入，使凸起顶入对应的通孔中进行固定，外罩100的边沿需要刮擦底座600的卡勾，此过程有把底座600镀层刮伤的隐患。
发明内容
本发明实施例的目的在于提供一种模块结构，以解决现有技术模块结构不能自动复位且电磁屏蔽效果差装配时容易刮伤底座的问题。
本发明提供一种模块结构，所述模块结构包括固定在拉环上的扭簧；
所述扭簧包括左扭簧和右扭簧，在所述拉环上对称设置；
所述左扭簧包括依次连接的第一撑杆、第一螺旋孔、第一连接杆和第二螺旋孔；所述右 扭簧包括依次连接的第二撑杆、第三螺旋孔、第二连接杆和第四螺旋孔；
所述第一撑杆1及所述第二撑杆为直杆状，所述第一连接杆及所述第二连接杆为L形杆状；
所述第二螺旋孔套在所述拉环的第三转轴的外侧，经过L形杆状的所述第一连接杆后，所述第一螺旋孔套在第一转轴的外侧，所述第一撑杆的方向为斜向上与所述拉环所在平面形成小于90°夹角的方向；
所述第四螺旋孔套在所述拉环的第四转轴的外侧，经过L形杆状的所述第二连接杆后，所述第三螺旋孔套在第二转轴的外侧，所述第二撑杆的方向为斜向上与所述拉环所在平面形成小于90°夹角的方向。
本发明具有的有益效果包括：
1、拉环可以自动复位，无需人工恢复，使用方便；
2、安装卸载装置的零件组装速度快，可靠性高；
3、模块无装配缝隙，屏蔽效果好。
