Description

带光学透镜的光模块光接口组件及其制造方法 技术领域
本发明属于光通信技术领域，更具体地说涉及一种带光学透镜的光模块光接口组件及其制造方法。
背景技术
光模块光接口组件无论是光发射光接口组件，还是光接收光接口组件，都包括金属接头、以及与金属接头两端耦合连接的光学次模块和外部光纤，并通过TO定位环固定光学次模块。为了提高和保证光源效率，通常会在金属接头和光源之间设置准直透镜，并且一般设计会将准直透镜安装在TO定位环靠近金属接头一端。光发射光路的设计一般是光源-透镜-陶瓷插芯内光纤-外部光纤，要经过3次光路的对准耦合；光接收光路的设计一般是外部光纤-透镜-光源，要经过2次的对准耦合，耦合对准的工艺复杂成本比较高，同时由于光发射与光接收采用不同的结构，导致物料管理成本增加。
现有的该光模块光接口组件具有诸多的缺陷。首先，现有的被应用于发射端和被应用于接收端的该光模块光接口组件的结构和类型均不相同，这导致该光模块光接口组件的制造成本无法被有效地降低，且导致该光模块光接口组件的管理难度被增加。再次，由于被应用于发射端的该光模块光接口组件的原理是“光源-透镜-陶瓷插芯内光纤-外部光纤”，因此，在制造被应用于发射端的该光模块光接口组件时需要对组成该光模块光接口组件的各个部件进行3次光路的对准耦合；相应地，由于被应用于接收端的该光模块光接口组件的原理是“外部光纤-透镜-光源”，因此，在制造被应用于接收端的该光模块光接口组件时需要对组成该光模块光接口组件的各个部件进行2次光路的对准耦合，这不仅导致该光模块光接口组件的制造工序被增加和导致该光模块光接口组件的制造成本增加，而且由于该光模块光接口组件在被制造的过程中需要进行多次光路的对准耦合，导致该光模块光接口组件的产品良率较低且可靠性较差。另外，现有的该光模块光接口组件需要使用到陶瓷插芯内光纤，这不仅因增加了该光模块光接口组件的零部件而导致该光模块光接口组件的制造工序增加和导致该光模块光接口组件的制 造成本增加，而且在制造该光模块光接口组件的过程中，陶瓷插芯内光纤很容易损坏，从而严重地制约了该光模块光接口组件的生产效率。最后，现有的该光模块光接口组件的金属接头、陶瓷插芯和透镜等各个部件是在分别被制作完成后再组装在一起的，这导致现有的该光模块光接口组件的精度不高，不能够满足对光纤传输能力要求较高的环境中使用。
发明内容
本发明提出了一种带光学透镜的光模块光接口组件，对光模块光组件的光路结构进行完全不同的设计，采用统一的结构设计满足光发射和光接收两种光模块的需求。光发射的光路结构为光源-透镜-外部光纤，光接收的光路设计为外部光纤-透镜-光源，大大简化组件结构，同时对于光发射模块去掉陶瓷插芯而大幅度降低组件成本。
本发明具体是通过以下技术方案来实现的：

实施例2
示例：
参考本发明的说明书附图之附图2至图10，依本发明的一较佳实施例的一带光学透镜的光模块光接口组件在接下来的描述中被阐述，其中所述带光学透镜的光模块光接口组件包括一连接主体10和一光学透镜20。值得一提的是，在本 文接下来的描述和说明中，将所述带光学透镜的光模块光接口组件简化成一光模块光接口组件，以便于说明和理解，本领域的技术人员可以理解的是，将所述带光学透镜的所述光模块光接口组件简化成所述光模块光接口组件并不应被视为对本发明的内容和范围的限制。也就是说，所述光模块光接口组件包括所述连接主体10和所述光学透镜20。
进一步地，参考附图3，所述连接主体10具有一内壁11，其中所述内壁11用于界定一成型空间12。也就是说，所述连接主体10具有所述成型空间12，以供成型所述光学透镜20。
所述光学透镜20具有一第一端面21和一第二端面22，其中所述光学透镜20的所述第一端面21和所述第二端面22相互对应。尽管在附图3中以所述光学透镜20的所述第一端面21和所述第二端面22均被实施为凸面为例，来说明本发明的所述光模块光接口组件的特征和优势，但本领域的技术人员应当理解，所述光学透镜20的所述第一端面21和所述第二端面22的实施方式不限于凸面。例如在另外的一些实例中，所述光学透镜20的所述第一端面21和所述第二端面22可以分别被实施为平面或者凹面或者其他的非球面。因此，所述光学透镜20的所述第一端面21和所述第二端面22的类型在本发明的所述光模块光接收组件中不受限制。
所述光学透镜20被成型和被保持在所述连接主体10的所述成型空间12，以形成所述光模块光接收组件，其中所述光学透镜20的所述第一端面21和所述第二端面22分别对应于所述连接主体10的两个端部，例如所述光学透镜20的所述第一端面21和所述第二端面22分别朝向所述连接主体10的两个端部。
具体地，所述连接主体10进一步具有一第一连接端13和一第二连接端14，其中所述第一连接端13和所述第二连接端14相互对应，所述连接主体10的所述内壁11向所述连接主体10的两个端部分别延伸以分别连接于所述第一连接端13和所述第二连接端14。所述光学透镜20在被安装于所述连接主体10的所述成型空间12后，所述光学透镜20的所述第一端面21朝向所述连接主体10的所述第一端部13，所述光学透镜20的所述第二端面22朝向所述连接主体10的所述第二端部14。
所述连接主体10供连接一光学次模块30和一外部光纤40，其中当所述连接主体10连接所述光学次模块30和所述外部光纤40后，所述光学透镜20被保 持在所述光学次模块30和所述外部光纤40之间，并且所述光学透镜20的所述第一端面21朝向所述光学次模块30，所述光学透镜20的所述第二端面22朝向所述外部光纤40。
进一步地，所述光学次模块30被安装于所述连接主体10的所述第一端部13，所述外部光纤40被安装于所述连接主体10的所述第二端部14，通过这样的方式，使得所述连接主体10连接所述光学次模块30和所述外部光纤40。
优选地，所述光学次模块30的端部通过自所述所述连接主体10的所述第一端部13插入到所述连接主体10的内部的方式被安装于所述连接主体10。相应地，所述外部光纤40的端部通过自所述连接主体10的所述第二端部14插入到所述连接主体10的内部的方式被安装于所述连接主体10，通过这样的方式，使得所述光学次模块30、所述光学透镜20和所述外部光纤40在所述连接主体10的内部互动，以避免外部光线等污染物干扰所述光学次模块30、所述光学透镜20和所述外部光纤40的互动位置，从而保证和提高光纤传输能力。
值得一提的是，当所述光学次模块30的端部自所述连接主体10的所述第一端部13插入到所述连接主体10的内部和所述外部光纤40的端部自所述连接主体10的所述第二端部14插入到所述连接主体10的内部后，所述光学次模块30和所述光学透镜20的所述第一端面21保持预设距离，所述外部光纤40和所述光学透镜20的所述第二端面22保持预设距离。也就是说，所述光学次模块30不与所述光学透镜20的所述第一端面21直接接触，所述外部光纤40不与所述光学透镜20的所述第二端面22直接接触。
所述连接主体10的所述内壁11分别在所述第一端部13和所述第二端部14界定一第一容纳空间15和一第二容纳空间16。也就是说，所述连接主体10在所述第一端部13设有所述第一容纳空间15和在所述第二端部13设有所述第二容纳空间16。所述成型空间12分别向所述连接主体10的所述第一端部13和所述第二端部14延伸，以连通于所述第一容纳空间15和所述第二容纳空间16。
参考附图4，所述光学次模块30的端部被安装和被保持在所述连接主体10的所述第一容纳空间15，所述外部光纤40的端部被安装和被保持在所述连接主体10的所述第二容纳空间16，从而藉由所述连接主体10连接所述光学次模块30和所述外部光纤40。
可以理解的是，当所述光学次模块30自所述连接主体10的所述第一端部 13被安装于所述第一容纳空间15和所述外部光纤40自所述连接主体10的所述第二端部14被安装于所述第二容纳空间16后，所述光学次模块30的中轴线、所述光学透镜20的中轴线和所述外部光纤40的中轴线相互重合，以保证光纤传输能力。
在所述光学次模块30自所述连接主体10的所述第一端部13被安装于所述第一容纳空间15和所述外部光纤40自所述连接主体10的所述第二端部14被安装于所述第二容纳空间16后，使所述光学次模块30的中轴线、所述光学透镜20的中轴线和所述外部光纤40的中轴线相互重合的方式在本发明的所述光模块光接口组件中不受限制。
例如在一个示例中，在所述光学透镜20被成型于所述连接主体10的所述成型空间12后，所述光学透镜20的中轴线和所述连接主体10的中轴线相互重合，在将所述光学次模块30和所述外部光线40分别安装于所述连接主体10的所述第一容纳空间15和所述第二容纳空间16后，使所述光学次模块30的中轴线和所述外部光线40的中轴线分别与所述连接主体10的中轴线相互重合，从而使得所述光学次模块30的中轴线、所述光学透镜20的中轴线和所述外部光纤40的中轴线相互重合。
在另一个示例中，在所述光学透镜20被成型于所述连接主体10的所述成型空间12后，所述光学透镜20的中轴线和所述连接主体10的中轴线相互重合，在将所述光学次模块30和所述外部光线40分别安装于所述连接主体10的所述第一容纳空间15和所述第二容纳空间16后，可以直接使所述光学次模块30的中轴线和所述外部光线40的中轴线分别与所述光学透镜20的中轴线相互重合。
另外，在本发明的所述光模块光接口组件的一个示例中，所述连接主体10的所述内壁11可以是一个完整的表面，即，所述连接主体10的所述第一容纳空间15、所述成型空间12和所述第二容纳空间16的内径一致。
在本发明的所述光模块光接口组件的另一个示例中，所述连接主体10的所述内壁11进一步包括一第一内壁111、一第二内壁112以及一第三内壁113，其中所述第一内壁111位于所述连接主体10的所述第一端部13以用于界定所述第一容纳空间15，所述第三端部113位于所述链接主体10的所述第二端部14以用于界定所述成型空间12和所述第二容纳空间15，其中所述第二内壁112分别连接于所述第一内壁111和所述第三内壁113。优选地，所述第一内壁111和所 述第二内壁112可以相互垂直，所述第二内壁112和所述第三内壁113可以相互垂直，参考附图3。
值得一提的是，尽管附图3中示出了所述第三内壁113界定的所述成型空间12和所述第二容纳空间16的内径一致，在其他的示例中，所述成型空间12和所述第二容纳空间16也可以由具有不同内径的内壁形成，即，所述成型空间12和所述第二容纳空间16的内径不一致，本发明的所述光模块光接收组件在这方面不受限制。
进一步参考附图3，所述光学透镜20具有一周壁23，其中所述周壁23分别向所述光学透镜20的所述第一端面21和所述第二端面22延伸，以连接于所述第一端面21和所述第二端面22的边缘。在所述光学透镜20被成型于所述连接主体10的所述成型空间12后，所述光学透镜20的所述周壁23和所述连接主体10的用于界定所述成型空间12的所述内壁11贴合在一起，从而使得所述光学透镜20和所述连接主体10的相对位置不会发生改变，以保证所述光学透镜20的中轴线和所述连接主体10的中轴线相互重合，以提高所述光模块光接口组件的产品良率。
也就是说，所述光学透镜20和所述连接主体10能够通过使所述光学透镜20的所述周壁23和所述连接主体10的所述内壁11贴合在一起的方式，使所述光学透镜20吻合于所述连接主体10的所述内壁11，从而在所述光模块光接口组件被运输和被安装时，所述光学透镜20和所述连接主体10的相对位置不会发生改变，尤其是所述光学透镜20不会做相对于所述所述连接主体10的径向运动，通过这样的方式，保证所述光学透镜20的中轴线和所述连接主体10的中轴线相互重合。
进一步参考附图3，所述连接主体10的所述内壁11设有至少一定位槽114，其中每个所述定位槽114分别连通于所述成型空间12，所述光学透镜20的所述周壁23设有至少一定位元件24，其中在所述光学透镜20成型于所述连接主体10的所述成型空间12的同时，所述光学透镜20的每个所述定位元件24分别以成型于所述连接主体10的每个所述定位槽114的方式，使所述定位元件24被定位于所述定位槽114，从而使所述光学透镜20被保持在所述连接主体10的所述成型空间12。另外，所述光学透镜20的每个所述定位元件24和所述连接主体10的每个所述定位槽114能够相互配合，以阻止所述光学透镜20做相对于所述 连接主体10的轴向运动，从而保证所述光模块光接口组件的精度。
在所述光模块光接口组件的一个示例中，所述连接主体10的所述定位槽114的数量被实施为多个时，每个所述定位槽114可以相互间隔地设于所述内壁11。优选地，任意两个所述定位槽114之间的距离相等。所述光学透镜20的所述定位元件24的数量、位置和尺寸和所述连接主体10的每个所述定位槽114的数量、位置和尺寸相互匹配。
在所述光模块光接口组件的另外一个示例中，所述连接主体10的所述定位槽114的数量可以被实施为一个，并且所述定位槽114被优选地实施为环形，即，所述连接主体10具有一个环形的所述定位槽114。所述光学透镜20的所述定位元件24的数量也被实施为一个，并且所述定位元件24被优选地实施为环形，即，所述光学透镜20具有一个环形的所述定位元件24。当所述光学透镜20的所述定位元件24被定位于所述连接主体10的所述定位槽114时，所述光学透镜20被可靠地保持在所述连接主体10的所述成型空间12内。
参考附图11，在本发明的所述光模块光接口组件的一个变形实施方式中，所述光学透镜20可以设有所述定位槽114，所述连接主体10的所述内壁11设有所述定位元件24，从而所述光模块光接口组件以所述连接主体10的所述定位元件24被定位于所述光学透镜20的所述定位槽114的方式，使所述光学透镜20被成型和被保持在所述连接主体10的所述成型空间12内。
依本发明的所述光模块光接口组件的另一个方面，所述光模块光接口组件进一步包括一光接口单元50和一保持臂单元60。
所述光接口单元50包括一管状的接口元件51和所述光学透镜20，其中所述接口元件51形成所述成型空间12，所述光学透镜20通过被安装于所述成型空间12的方式被保持在所述接口元件51的内部。
所述保持臂单元60包括一管状的第一保持臂61和一管状的第二保持臂62，其中所述第一保持臂61和所述第二保持臂62分别延伸自所述接口元件51的两端，其中所述第一保持臂61形成所述第一容纳空间15，以供容纳所述光学次模块30，所述第二保持臂62形成所述第二容纳空间16，以供容纳所述外部光纤40。
值得一提的是，当所述光学次模块30的端部被安装于所述第一保持臂61形成的所述第一容纳空间15时，所述第一保持臂61环绕在所述光学次模块30的 端部的四周。优选地，所述第一保持臂61进一步具有至少一固定通道，其中每个所述固定通道分别连通于所述第一容纳空间15和所述连接主体10的外部环境，当所述光学次模块30的端部被安装于所述第一保持臂61形成的所述第一容纳空间15时，通过每个所述固定通道能够在所述第一保持臂61的外部将所述光学次模块30和所述第一保持臂61固定在一起，从而避免所述光学次模块30做相对于所述连接主体10的移动，以保证所述光模块光接口组件在被使用时的可靠性。例如，所述第一保持臂61的所述固定通道可以是一个激光焊接通道，以允许在所述连接主体10的外部通过所述固定通道利用激光焊接的方式将被安装在所述第一容纳空间15的所述光学次模块30的端部和所述第一保持臂61固定在一起。
相应地，当所述外部光纤40的端部被安装于所述第二保持臂62形成的所述第二容纳空间16时，所述第二保持臂62环绕在所述外部光纤40的端部的四周。
优选地，所述光学透镜20在本发明的所述光模块光接口组件中被实施为准直透镜，以使光线在穿过所述光学透镜20时能够被进行准直矫正，通过这样的方式，提高所述光模块光接口组件的精度和所述光模块光接口组件在被使用时的可靠性。
另外，进一步参考附图3，所述连接主体10进一步包括一载体110和一硬化层120，其中所述载体110呈管状，所述硬化层120形成于所述载体110的表面，也就是说，所述连接主体10的所述内壁11也是所述硬化层120形成的，通过这样的方式，能够提高所述光模块光接口组件的精度。当所述光学次模块30和所述外部光纤40分别被安装于所述连接主体10的所述第一容纳空间15和所述第二容纳空间16时，所述光学次模块30和所述外部光纤40分别和所述连接主体10的所述硬化层120接触，通过这样的方式，一方面能够保证所述光学次模块30的中轴线、所述光学透镜20的中轴线和所述外部光纤40的中轴线重合，另一方面当所述光学次模块30和所述外部光纤40被多次安装于所述第一容纳空间15和所述第二容纳空间16和多次被从所述第一容纳空间15和所述第二容纳空间16红拆卸时，所述光学次模块30和所述外部光纤40分别与所述硬化层120反复地接触和摩擦而不会对所述硬化层120造成磨损，以在所述光模块光接口组件在被多次的时候之后仍然能够保证精度。
在本发明的一个实施例中，所述连接主体10的所述载体110和所述硬化层 120分别由不同的材料形成，例如可以先形成所述载体110，然后再在所述载体110的内壁形成所述硬化层120。在另一个实施例中，所述连接主体10的所述载体110和所述硬化层120也可以由相同的材料形成，例如可以先形成所述载体110，然后通过氮化处理等工艺使所述载体110的内壁硬化以形成所述硬化层120。
值得一提的是，所述连接主体10的所述载体110的材料不受限制，例如所述载体110可以是金属件，即，所述连接主体10可以形成本发明在附图1揭露的第一个实施例的所述金属接头1。优选地，所述连接主体10的所述载体110可以是由不锈钢材料制成的，通过这样的方式，能够便于将所述连接主体10进行安装，以使用本发明的所述光模块光接口组件。当然，本领域的技术人员可以理解的是，所述连接主体10的所述载体110也可以由其他的材料制成，例如合金材料或者高分子材料。
参考本发明的说明书附图之图5A和图5B，分别是所述光模块光接口组件在被实施为发射端和接收端的示例，也就是说，本发明的所述光模块光接口组件不仅能够被应用于发射端，而且能够被应用于接收端，这样，在安装所述光模块光接口组件时，不需要再对所述光模块光接口组件的类型进行区分，以便于使用。
具体地，参考附图5A，当所述光模块光接口组件被实施为发射端时，所述光学次模块30产生的光线在穿过所述光学透镜20时，能够被所述光学透镜20进行光学准直矫正，以使穿过所述光学透镜20的光线能够进入所述外部光纤40和被所述外部光纤40传输。参考附图5B，当所述光模块光接口组件被实施为接收端时，所述外部光纤40传输的光线在穿过所述光学透镜20时，能够被所述光学透镜20进行光学准直矫正，以使穿过所述光学透镜20的光线能够被所述光学次模块30接收。也就是说，无论所述光模块光接口组件被实施为发射端和被实施为接收端，所述光学透镜20均能够对穿过所述光学透镜20的光线进行光学准直矫正，以保证光纤传输能力。
参考本发明的说明书附图之图6至图10，是依本发明的上述较佳实施例的所述光模块光接口组件的制造流程示意图。
具体地，本发明可以先提供所述连接主体10和用于形成所述光学透镜20的一成型材料80。
更具体地，首先提供呈管状的所述载体110，例如所述载体110可以通过注 塑的方式形成，也可以通过铣床铣成，本发明在这方面不受限制。优选地，所述载体110设有至少一个所述定位槽114。再次对所述载体110的表面进行硬化处理，例如可以通过对所述载体110的表面进行氮化处理的方式在所述载体110的表面形成所述硬化层120，通过这样的方式，能够提高所述连接主体10的表面的硬度，尤其是能够提高所述连接主体10的所述内壁11的硬度，从而无论是在所述连接主体10的所述成型空间12内形成所述光学透镜20而形成所述光模块光接口组件时，还是在使用所述光模块光接口组件时，都能够保证所述光模块光接口组件的精度。然后，去除所述连接主体10的所述第一端部13和所述第二端部14的所述硬化层120，例如可以通过切削或者研磨等类似的方式去除所述连接主体10的所述第一端部13和所述第二端部14的所述硬化层120，以使所述载体110在所述连接主体10的所述第一端部13和所述第二端部14裸露，从而便于通过所述第一端部13和所述第二端部14将所述连接主体10安装。在一些实例中，还可以对所述连接主体10的所述内壁11进行研磨以进一步提高所述光模块光接口组件的精度。
进一步参考附图9和图10，将所述成型材料80加入到所述连接主体10的所述成型空间12，然后分别在所述连接主体10的所述第一端部13和所述第二端部14分别通过一第一成型夹具91和一第二成型夹具92使所述成型材料80在所述连接主体10的所述成型空间12内形成所述光学透镜20。值得一提的是，所述第一成型夹具91和所述第二成型夹具92的成型面93的形状决定了所述光学透镜20的所述第一端面21和所述第二端面22的形状。可以理解的是，在藉由所述第一成型夹具91和所述第二成型夹具92分别在所述连接主体10的所述第一端部13和所述第二端部14施压于所述成型材料80的过程中，还可以加热，以藉由所述第一成型夹具91和所述第二成型夹具92通过热压的工艺使所述光学透镜20在所述连接主体10的所述成型空间12内成型，从而制得所述光模块光接口组件。值得一提的是，在藉由所述第一成型夹具91和所述第二成型夹具92使所述光学透镜20在所述连接主体10的所述成型空间12内成型时，可以以所述连接主体10的所述成型空间12为基准放入到藉由所述第一成型夹具91和所述第二成型夹具92组成的成型模具90中，以进一步提高所述光模块光接口组件的精度。
也就是说，所述成型模具90具有一个第一成型夹具91和一个所述第二成型 夹具92，以供使所述光学透镜20成型在所述连接主体10的所述成型空间12。
附图12示出了本发明的所述光模块光接口组件的一个变形实施方式，其中所述连接主体10的所述内壁11设有至少一第一保持槽115，每个所述第一保持槽115分别连通所述成型空间12，所述光学透镜20的所述周壁23设有至少一第二保持槽231，其中所述光模块光接口组件进一步包括至少一保持元件70，其中当所述光学透镜20被安装在所述连接主体10的所述成型空间12时，所述光学透镜20的至少一个所述第二保持槽231和所述连接主体10的至少一个所述第一保持槽115相互对应，所述保持元件70同时被保持在所述连接主体10的所述第一保持槽115和所述光学透镜20的所述第二保持槽231，通过这样的方式，能够使所述光学透镜20被保持在所述连接主体10的所述成型空间12。
也就是说，在本发明的所述光模块光接口组件的这个实施例中，所述光学透镜20没有成型于所述连接主体10的所述成型空间12，而使在分别提供所述连接主体10和所述光学透镜20后，将所述光学透镜20安装于所述连接主体10的所述成型空间12。
优选地，当所述光学透镜20被安装在所述连接主体10的所述成型空间12时，所述光学透镜20的每个所述第二保持槽231和所述连接主体10的每个所述第一保持槽115分别对应。
在所述光模块光接口组件的一个具体示例中，所述保持元件70可以由胶水固化形成。具体地，在制造本发明的所述光模块光接口组件的过程中，可以先将呈流体状的所述胶水施凃在所述光学透镜20的每个所述第二保持槽231，例如可以通过点胶机将所述胶水施凃在所述光学透镜20的每个所述第二保持槽231，然后将所述光学透镜20安装于所述连接主体10的所述成型空间12，以使每个所述光学透镜20的每个所述第二保持槽231和所述连接主体10的每个所述第一保持槽115相互对应，从而使得位于所述光学透镜20的每个所述第二保持槽231所述胶水的一部分能够流动到所述连接主体10的每个所述第一保持槽115，后续，在使胶水固化后形成被同时保持在所述连接主体10的所述第一保持槽115和所述光学透镜20的所述第二保持槽231的所述保持元件70，以将所述光学透镜20和所述连接主体10固定。当然，也可以先将所述胶水施凃在所述连接主体10的所述第一保持槽115，然后在所述光学透镜20被安装在所述连接主体10的所述成型空间12后，使位于所述连接主体10的所述第一保持槽115的所述胶水 的一部分流动到所述光学透镜20的所述第二保持槽231。
可以理解的是，所述胶水在所述连接主体10的所述第一保持槽115和所述光学透镜20的所述第二保持槽115内固化的方式不受限制，例如可以加热固化或者降温固化等，其根据选择的所述胶水的类型被确定。当然，用于形成所述保持元件70的物质也可以不是所述胶水，其只要能够在固化后处于稳定的固体形态的材料均可。
附图13示出了本发明的所述光模块光接口组件的一个变形实施方式，其中所述连接主体10的所述第一保持槽115形成于所述第二内壁12和所述第三内壁113的连接处，以使得所述第一保持槽115连通于所述第一容纳空间15，其中所述光学透镜20的所述第二保持槽231形成于所述周壁23和所述第一端面21的连接处。当所述光学透镜20被安装于所述连接主体10的所述成型空间12时，所述连接主体10的所述第一保持槽115和所述光学透镜20的所述第二保持槽231相互对应且均连通于所述第一容纳空间15，从而可以通过所述第一容纳空间15将所述胶水施凃在所述连接主体10的所述第一保持槽115和所述光学透镜20的所述第二保持槽231，以在所述胶水固化后，形成同时被保持在所述连接主体10的所述第一保持槽115和所述光学透镜20的所述第二保持槽231的所述保持元件70，从而固定所述光学透镜20和所述连接主体10，以制得所述光模块光接口组件。
附图14示出了本发明的所述光模块光接口组件的另一个变形实施方式，其中所述保持元件70可以一体地延伸于所述光学透镜20的所述第一端面21，在将所述光学透镜20安装于所述连接主体10的所述成型空间12时，所述保持元件70被保持在所述连接主体10的所述第一保持槽115，以固定所述光学透镜20和所述连接主体10，以制得所述光模块光接口组件。
附图15示出了本发明的所述光模块光接口组件的另一个变形实施方式，其中所述保持元件70可以一体地延伸于所述连接主体10的内壁，从而在将所述光学透镜20安装于所述连接主体10的所述成型空间12时，所述保持元件70被保持在所述光学透镜20的所述第二保持槽231，以固定所述光学透镜20和所述连接主体10，以制得所述光模块光接口组件。
