下面结合附图详细说明本申请的具体实施方式：
本申请提供一种光口组件及光模块，其中，光口组件1用于提供连接光纤的物理接口，以使两段光纤能够连接实现光纤通信。
光口组件1的基本组成及其工作原理大致如下：
如图1所示，光口组件1中包括连接件100和适配件200，其中连接件100相对的两端中有一端连接有光纤110，另一端用于与另一个连接件100连接。为方便两个连接件100连接，可以将其中一个连接件100上设置插针，另一个连接件100上设置插孔，通过插针插入插孔中以实现连接件100中连接的光纤能准确连接。光口组件1中的适配件200具有中空的容纳腔210，容纳腔210贯穿适配件200，两个连接件100分别从适配件200的相对的两端伸入容纳腔210中进行连接，以实现两个连接件100连接的光纤110连接，同时连接件100与适配件200固定，以使连接件100能稳定的连接。
在本申请实施例中，如图2所示，光口组件1包括连接件100、适配件200、屏蔽件300，其中连接件100沿第一方向的一端连接有光纤110。具体的，连接件100在第一方向上具有相对的两端，其中第一方向为光纤110的延伸方向，也即如图2所示的左右方向，光纤110与该相对的两端中的 一端连接。光纤110的数量可以是一条，也可以是多条，其具体的数量可以根据实际使用的情况来选择。连接件100与适配件200连接，其中，适配件200具有沿第一方向(如图2所示的左右方向)延伸的容纳腔210，连接件100远离光纤110的一端沿第一方向(如图2所示的左右方向)伸入容纳腔210。具体的，适配件200由壳体220环绕而成，壳体220内部形成有中空的容纳腔210，容纳腔210沿光纤110的延长方向贯通适配件200，用作容纳连接件100的空腔，容纳腔210与外界连通，在进行装配时，两个连接件100伸入容纳腔210内连通并与适配件200固定，以实现光纤110能稳定的连通。可选的，适配件200可以是塑料制品，也可以是金属制品。
结合图2和图3所示，光口组件1中的屏蔽件300具有中空的匹配腔310，屏蔽件300沿第一方向(如图3所示的左右方向)的相对两端开设与匹配腔310连通的开口，适配件200通过一个开口伸入匹配腔310中固定，另一个开口用于插入光纤110。具体的，屏蔽件300环绕在适配件200的壳体220的外表面上以包裹适配件200，屏蔽件300由金属制成，例如，铜、铁等；其中，屏蔽件300可以完全包裹该适配件200，也可以部分包裹适配件200。可选的，屏蔽件300可以是一体成型，也可以是由多个壁板拼接形成，壁板的拼接方式可以是焊接、粘接等方式。例如，屏蔽件300相对的两端开设有开口，两个开口与匹配腔310连通，其中一个开口用于与将适配件200装入匹配腔310中，另一个开口用于让光纤110伸出屏蔽件300。为了方便说明，将其中一个开口称为第一开口320，另一个开口称为第二开口330。若采用的屏蔽件300是一体成型时，光口组件1的安装步骤是，首先将带有光纤110的连接件100远离光纤110的一端伸入适配件200的容纳腔210中，连接件100与光纤110的连接处伸入该容纳腔210中，且光纤110伸出该容纳腔210并延伸出适配件200，屏蔽件300通过第一开口320安装在适配件200的壳体220的外表面上，并将连接件100的光纤110的连接处包裹在屏蔽件300内，光纤110从第二开口330伸出屏蔽件300。 屏蔽件300中的匹配腔310的尺寸稍大于适配件200的外形尺寸，以使屏蔽件300能顺利的安装在适配件200上的同时也能与适配件200的壳体220紧密接触。
如图3所示，第二开口330的尺寸与光纤110沿第二方向的截面尺寸基本相同；第一方向(如图3所示的左右方向)与第二方向基本垂直。其中，第二方向大致垂直于光纤110长度的延伸方向，也即如图3所示的上下方向。具体的，光纤110沿第二方向(如图3所示的上下方向)的截面即其横截面的尺寸与屏蔽件300用于光纤110伸出的第二开口330的尺寸基本相同，所谓基本相同是考虑到装配误差，不要求绝对相同，也即第二开口330的大小正好容纳光纤110穿过，光纤110可以与围城该第二开口330的金属板接触。光口组件在安装过程中，首先将连接件100与适配件200固定，而连接件100上连接有光纤110，连接件100与适配件200固定后，连接件100与光纤110的连接处相对于适配件200的位置就相对固定，屏蔽件300也与适配件200相对固定，从而屏蔽件300与连接件100的相对位置也固定，也即连接件100上连接的光纤110也与屏蔽件300的位置相对固定，从而方便屏蔽件300上事先开设供光纤110穿过的第二开口330，并在不担心损伤光纤110的基础上使屏蔽件300上的第二开口330最小化。
本申请实施例提供的光口组件，包括连接件、适配件和屏蔽件。连接件上连接有光纤，适配件具有容纳腔，连接件伸入该容纳腔中固定，以使连接件与适配件的相对位置固定，屏蔽件具有中空的匹配腔，适配件伸入该匹配腔以固定连接适配件与屏蔽件，以使屏蔽件与适配件的相对位置固定，从而屏蔽件与光纤的位置也相对固定。本申请通过屏蔽件全部包裹在适配件上，增加了屏蔽件的包裹范围，同时也限定屏蔽件与适配件的相对位置，从而进一步地限定了屏蔽件与光纤的相对位置，进而确定了屏蔽件上供光纤穿过的第二开口的位置，并且由于该第二开口与光纤的相对位置固定，可以将该第二开口的尺寸与光纤垂直光纤长度方向的尺寸的大小大 致相同，以实现使第二开口最小化，进而减少该第二开口处的电磁泄漏，增强了电磁屏蔽的效果。
在一些实施例中，如图3和图4所示，屏蔽件300包括可拆卸连接的第一屏蔽盖340和第二屏蔽盖350，第一屏蔽盖340和第二屏蔽盖350连接以形成匹配腔310。其中，可拆卸连接可以是滑动连接，也可以是卡扣连接。例如，第一屏蔽盖340包括第一侧壁341、第二侧壁342、第三侧壁343和第一底壁344，其中，第一侧壁341与第二侧壁342分别连接到第三侧壁343相对的两端，形成一个大致U型结构，且第一侧壁341、第二侧壁342、第三侧壁343均连接在第一底壁344上。第二屏蔽盖350包括第四侧壁351、第五侧壁352、第六侧壁353和第二底壁354；其中，第四侧壁351与第一侧壁341连接，第五侧壁352与第二侧壁342连接，第六侧壁353和第三侧壁343连接。可选的，第二开口330可以单独设置在第三侧壁343或者第六侧壁353上，也可以同时设置在第三侧壁343和第六侧壁353上。可选的，第一侧壁341、第二侧壁342中至少有一个设有一个凸起，第四侧壁351、第五侧壁352相对应的至少设有一个凹槽。通过该凸起伸入到该凹槽中以固定第一屏蔽盖340和第二屏蔽盖350。可选的，如图5所示，第一屏蔽盖340还可以为平板状，第二屏蔽盖350包括第四侧壁351、第五侧壁352、第六侧壁353和第二底壁354，其中，第四侧壁351和第五侧壁352平行设置并分别与第二底壁354的一端连接，第六侧壁353与第四侧壁351、第五侧壁352、第二底壁354连接，第六侧壁353设有第二开口330用于光纤110穿过，第四侧壁351和第五侧壁352上均设有滑道，第一屏蔽盖340通过该滑道与第四侧壁351和第五侧壁352连接，形成相对的两端均具有开口的匹配腔310。
屏蔽件包括第一屏蔽盖与第二屏蔽盖，通过第一屏蔽盖与第二屏蔽盖之间可以拆卸连接，便于屏蔽件从适配件上拆装，提高装配的效率。
在一些实施例中，如图6所示，第一屏蔽盖340设有第一限位件345， 第二屏蔽盖350设有第二限位件355，第一限位件345与第二限位件355抵接以限制第一屏蔽盖340相对于第二屏蔽盖350在第一方向(如图6所示的左右方向)的位移。具体的，第一屏蔽盖340设有相对设置第一侧壁341和第二侧壁342，第一侧壁341与第二侧壁342分别连接在第一底壁344上，第一限位件345与第一底壁344连接，其中，第一限位件345为平板状。第二屏蔽盖350设有相对设置的第四侧壁351和第五侧壁352，第四侧壁351和第五侧壁352分别连接在第二底壁354上，第二限位件355与第二底壁354连接，其中，第二限位件355也为平板状，且第二限位件355与第四侧壁351和第五侧壁352之间存在一定的间隙，第一限位件345可以插入该间隙中与第二限位件355抵接，也即第一限位件345与第二限位件355相互接触以阻止第一屏蔽盖340相对于第二屏蔽盖350在第一方向(如图6所示的左右方向)上位移。
第一屏蔽盖上的第一限位件伸入第二屏蔽盖上的第二限位件形成的间隙中，以使第一限位件只能在该间隙的范围内移动，从而限制第一屏蔽盖在第一方向上相对第二屏蔽盖的位移，同时方便第一屏蔽盖与第二屏蔽盖的装配。
在一些实施例中，如图6所示，第一屏蔽盖340和第二屏蔽盖350之中至少有一个设有定位件356以限制第一屏蔽盖340相对于第二屏蔽盖350在第二方向上的位移。具体的，定位件356可以为L型结构，其一端与第二底壁354连接，另一端用于支撑第一屏蔽盖340的第一底壁344。例如，定位件356设置为两个，分别与第四侧壁351、第六侧壁353连接，其中，定位件356远离第二底壁354的一端弯曲，在进行安装时，第一屏蔽盖340与第二屏蔽盖350安装，第一底壁344与定位件356抵接，以限制第一屏蔽盖340继续沿着第二方向(如图6所述的上下方向)，且定位件356与第二限位件355之间存在间隙，第一限位件345插入第二限位件355与定位件356的间隙中，以限制第一屏蔽盖340在第一方向上的位移。
定位件可以设置在第一屏蔽盖上，也可以设置在第二屏蔽盖上，通过安装时用定位件来限制第一屏蔽盖与第二屏蔽盖在第二方向(如图6所示的上下方向)的相对位置，从而实现安装定位。
在一些实施例中，如图6所示，第一屏蔽盖340上设有第一槽口3451，第二屏蔽盖350上设有第二槽口3551，在第一屏蔽盖340与第二屏蔽盖350连接的状态下，第一槽口3451与第二槽口3551连通形成另一个开口。另一个开口为第二开口330。具体的，第一槽口3451、第二槽口3551可以是U型槽口，两U型槽口相对设置，以便拼接成便于光纤110的第二开口330。例如，第一槽口3451设置在第一限位件345上，第二槽口3551设置在第二限位件355上，第一槽口3451的槽口与第二槽口3551的槽口口相对，在第一限位件345与第二限位件355连接时，第一槽口3451与第二槽口3551连接形成一个完整的第二开口330。
第一屏蔽盖与第二屏蔽盖进行安装时，通过第一槽口与第二槽口连接形成供光纤穿过的第二开口，方便第一屏蔽盖和第二屏蔽盖的直接拼装，而不用先将光线穿过第二开口后再进行第一屏蔽盖和第二屏蔽盖的安装。
在一些实施例中，如图7所示，第一屏蔽盖340包括第一本体3401和第一翻边3452，第一翻边3452设置在第一本体3401靠近第一槽口3451的位置，第一翻边3452沿第一方向(如图所示的左右方向)突出第一本体3401。靠近可以理解为两部件相接壤，即两部件之间的间距基本为零。具体的，第一翻边3452可以为长条状，设置在第一槽口3451的槽底处，可选的，第一翻边3452还可以设置在第一槽口3451的边缘，并沿光纤110的延伸方向突出第一本体3401，以增大光纤110与第一槽口3451的槽壁的接触面积。第二屏蔽盖350包括第二本体3501和第二翻边3552，第二翻边3552设置在第二本体3501靠近第二槽口3551的位置，第二翻边3552沿第一方向(如图7所示的左右方向)突出第二本体3501。靠近可以理解为两部件相接壤，即两部件之间的间距基本为零。具体的，第二翻边3552可以为长 条状，设置在第二槽口3551的槽底处，可选的，第二翻边3552还可以设置在第二槽口3551的边缘，并沿光纤110的延伸方向突出第二本体3501，以增大光纤110与第二槽口3551的槽壁接触面积。
第一翻边靠近第一槽口设置，第二翻边靠近第二槽口设置，通过第一翻边和第二翻边的设置，增加了光纤与第二开口的周围的接触面积，从而避免第一槽口和第二槽口的边缘过于锋利损坏光纤。
在一些实施例中，如图7所示，第一屏蔽盖340上设有第一凸起3411，第二屏蔽盖350上设有第一凹槽3511，第一凸起3411伸入第一凹槽3511以连接第一屏蔽盖340与第二屏蔽盖350。其中，第一凸起3411可以设置在第一侧壁341上，第一凹槽3511可对应设置在第四侧壁351。可选的，第一凸起3411可以设置为两个，分别设置在第一侧壁341和第二侧壁342上，第一凹槽3511也对应的设置两个，分别设置在第四侧壁351和第五侧壁352上。具体的，第一凸起3411向远离第一本体3401的方向突出，第一屏蔽盖340与第二屏蔽盖350安装时，第一凸起3411伸入第一凹槽3511中，从而固定第一屏蔽盖340和第二屏蔽盖350。可选的，第一屏蔽盖340上设有第一凹槽3511，第二屏蔽盖350上设有第一凸起3411，第一凸起3411伸入第一凹槽3511以可连接第一屏蔽盖340与第二屏蔽盖350。
在第一屏蔽盖上设置第一凸起，第二屏蔽盖上设置第一凹槽，或者在第一屏蔽盖上设有第一凹槽，第二屏蔽盖上设有第一凸起，通过在装配时，第一凸起伸入第二凹槽中，以使第一屏蔽盖能与第二屏蔽盖能稳定的固定。
在一些实施例中，如图7所示，屏蔽件300靠近一个开口的一端设有沿第一方向(如图7所示的左右方向)延伸的簧片360，簧片360具有向远离匹配腔310突出的弧度。其中，一个开口为第一开口320，具体的，簧片360具有一定的弹性，簧片360的一端与屏蔽件300连接，其中簧片360靠近第一开口320连接，可选的，簧片360可以设置为多个，围绕第一开口320设置。簧片360具有向匹配腔310突出的弧度，也即簧片360并非是呈 直线。在进行装配时，簧片360的一端与屏蔽件300连接，另一端与适配件200接触，以帮助屏蔽件300与适配件200连接紧密。
通过簧片围绕屏蔽件的第一开口设置，在装配时，簧片提供压力，以帮助屏蔽件与适配件之间紧密接触，有簧片具有弧度，以使簧片的最高点压要高于屏蔽件的高度，从而有助于屏蔽件接地，提高屏蔽件的电磁屏蔽的效果。
在一些实施例中，如图6和图7所示，屏蔽件300上设有第一卡合件370，适配件200上设有第二卡合件230，第一卡合件370和第二卡合件230相互卡合以固定屏蔽件与适配件200。具体的，第一卡合件370可以设置为两个，可以分别设置在第四侧壁351和第五侧壁352，可选的，第一卡合件370也可以设置在第一侧壁341和第二侧壁342上。第二卡合件230设置在适配件200的壳体220上，第二卡合件230也可以是相对应的设置为两个，通过第一卡合件370和第二卡合件230卡合连接，以使屏蔽件300紧密的连接在适配件200的壳体220上。例如，第一卡合件370为凸台，第二卡合件230为凹槽，在装配时，凸台伸入凹槽中固定，以使屏蔽件300与适配件200固定。
在一些实施例中，如图8所示，适配件200设有第一止位件240，连接件100上设有第二止位件120，第一止位件240与第二止位件120在第一方向(如图8所示的左右方向)上抵接。具体的，第一止位件240设置在容纳腔210中，第二止位件120设置在连接件100上，例如，第一止位件240为紧贴适配件200壳体220的内表面设置凸台，第二止位件120为台阶面，在进行装配时，连接件100伸入容纳腔210中，连接件100的台阶面与适配件200的凸台抵接，以使连接件100不能继续沿容纳腔210伸入，从而实现连接件100相对适配件200的限位。
本申请实施例还提供一种光模块，如图9所示，包括光口组件1和外壳400，其中，外壳400具有中空的安装槽410，光口组件1安装在安装槽 410中。具体的，光口组件1包括连接件100、适配件200、屏蔽件300，在进行安装时先将连接件100与适配件200、屏蔽件300安装完成后再与外壳400安装。外壳400为具有安装槽410的金属壳体，其安装槽410的形状与组装完成后的光口组件1的外形解决相匹配，以使光口组件1的外表面与外壳400充分接触。可选的，如图10所示，外壳400可以包括上壳体420和下壳体430，上壳体420上设有第二凹槽421，下壳体430上设有第三凹槽431，第二凹槽421与第三凹槽431相连接以形成安装槽410。
本申请通过先组装光口组件后再将组装完成后的光口组件安装在外壳里，减少了各元件单独安装的装配误差，限定了光纤相对壳体的位置，方便壳体预留空间供光纤放置，同时，在安装时光口组件能更好的与外壳紧密接触，提高光口组件的电磁屏蔽效果。
在一些实施例中，如图10所示，外壳400设有第一固定件440，光口组件1设有第二固定件250，第一固定件440与第二固定件250连接以将光口组件1固定在安装槽410中。具体的，第二固定件250设置在适配件200上，例如，第二固定件250为凸起，第一固定件440为相应的凹槽，在安装时，光口组件1通过第二固定件250的凸起伸入到第一固定件440的凹槽中进行固定，从而限定光口组件1的位置，方便光模块准确的组装。
以上所述，仅为本申请的较佳实施例而已，并非用于限定本申请的保护范围。
