  4. 根据权利要求3所述的一种应用在F5G系统内的1.8-4.2mm扁平型光电混合缆组件，其特征在于，所述光电连接头(2)的组装方法为：
    所述前壳(21)预组装：将所述导体底座(23)安装进所述前壳(21)下侧的所述导槽(211)内，推至顶部确保所述导体底座(23)前端两侧金属触点安装到位；
    所述后壳(22)预组装：准备一段PBT硬管伸入所述后壳(22)后使用胶水固定，待胶水凝固后拧上所述螺纹圈(24)，将所述扁平式光电混合缆(1)开剥去除所述外护套(14)的皮及芳纶，所述正极电源线(11)与所述负极电源线(12)反折并用胶带固定，将组装好的所述后壳(22)穿入φ0.6mm紧包光缆，PBT硬管全部穿入护套内。紧包光缆剥除φ0.6mm护套及涂覆层穿入所述弹簧26和已注胶的所述陶瓷插芯(25)，放置固化炉中固化；
    已固化好的所述陶瓷插芯(25)的尾柄距离所述后壳(22)前端需间隔，防止胶水粘连，将所述陶瓷插芯(25)装入所述前壳(21)中，使用组合工具将所述前壳(21)及所述后壳(22)组装完成，所述前壳(21)的凹口与所述后壳(22)的凸起完全卡住。所述后壳(22)的所述螺纹圈(24)预留两牙，预留出所述前壳(21)内空腔为保证后期尾套注塑填充形成倒扣，增加抗拉性；
    将所述正极电源线(11)和所述负极电源线(12)留出足够长度剥除4mm绝缘层，焊接在所述导体底座(23)后端的金属片焊接区，两端电源线的连接顺序为相反顺序，组成直流电源线提供稳定供电。将焊接完成后裸露部分使用热缩管包覆，其包覆长度需搭接到所述螺纹圈(24)与部分所述外护套(14)，防止注塑冲胶对光纤造成破坏。
