实施中,衬套主体一 100与衬套主体二 200的基板 10边沿插卡在光纤适配 器壳体插槽内, 进一步固定衬套主体一 100与衬套主体二 200的同时, 也将内 衬套整体固定在光纤适配器内, 内衬套整体自一侧插入光纤适配器壳体内, 并 通过盖板 6封闭。
在本实施例中, 为了方便内衬套的固定, 所述开口 5处相对的两侧壁上分 别设有供所述内衬套插入的插槽 16 , 衬套主体一 100、 衬套主体二 200的基板 10贴合后两侧边插入所述插槽 16中。 进一步, 在壳体 1与开口 5相对应的底 部具有供内衬套的基板 10的底侧边插入的底槽,这样内衬套可以方便的固定在 壳体 1中; 更进一步的, 盖板 6的下表面向下延伸出两个挡板, 两个挡板之间 形成收容内衬套基板 1 0的上侧边的顶槽, 盖板 6盖在开口 5上时, 基部 10的 上侧边插入到顶槽中。
为了配合光纤插头, 在插入时起到定位和导向作用, 第一插入端 2和所述 第二插入端 3的底部外表面对应每个光纤插头插孔分别设有与光纤插头配合的 第一导向定位槽 201、 301 , 所述第一插入端 2和第二插入端 3的顶部的内侧面 对应每个光纤插头插孔设有与光纤插头配合的第二导向定位槽 202、 302 , 这样 即使相邻插孔之间没有隔板, 也能保证每个光纤插头的导向和定位。
特别的, 所述第一插入端 2和所述第二插入端 3的顶部分别设有与光纤插 头相配合的锁定槽 7 , 待光纤插头插入时, 可起到相应固定锁止的作用。
同时, 为了方便该光纤适配器安装于挡板上, 相应的在壳体 1上设置弹片 8和挡耳 9 , 挡耳 9可根据安装位置的要求位于壳体的任意侧面; 为进一步增加 安装的稳固性, 在相应的挡耳 9上设置有螺釘孔 17 , 可在卡装的同时用螺釘进 一步与挡板紧固连接。
实施例二:
如图 4至 6所示, 给出了一种相邻插孔间距为 5匪的四芯光纤适配器的具 体结构, 相比于实施例 1 , 其相邻插孔间的间距为 5匪, 每个插孔宽度为 2. 5至 4. 5mm,在相邻插孔之间增加了隔板作为支撑,增强了壳体的强度,为方便生产, 所述弹片 8采用附加安装的金属弹片;挡耳 9上螺釘孔 17的形式为长圆形缺口。 同时挡耳 9设置于适配器的上方, 内衬套自一侧装入, 两侧不占用安装位置, 可进一步增加光纤连接器的横向安装密度。
实施例三:
如图 7所示, 给出了一种两芯光纤适配器的具体结构, 其挡耳 9相应更短, 且没有设置螺釘孔; 在插入端相邻的插槽间亦取消了相应的隔板, 插孔宽度可 设计为 2. 5至 4. 5匪, 相邻插孔间距根据需要设计为 3-5匪。 可满足不同的安装 密度。
实施例四: 如图 8所示, 给出了一种一体式光纤适配器的具体结构, 其采用台阶 18代 替挡耳, 亦可与弹片 8配合安装于挡板上, 同时在本实施例中, 弹片 8与壳体 一体成型, 可进一步降低生产成本。
以上适配器相应的装配方法为:
1 )、 将准直套管 4置于衬套主体一 100和衬套主体二 200扣合后形成的圆 柱形空腔中;
2 )、 将衬套主体一 1 00、 衬套主体二 200的基板 10贴合后两侧边插入壳体 开口 5处相对的两侧壁上的插槽 16中;
3 )、 将盖板 6装配在开口 5上形成封闭。
另外根据需要, 相应的在壳体上安装金属弹片。 制本发明的专利范围, 凡未脱离本发明技术精神所作出的等效实施或变更, 均 应包含于本申请所请求保护的专利范围中。
