DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention provide a photoelectric composite cable system, which solves the problem that the connection efficiency between the external device and the photoelectric composite cable is low and the position setting or variation of the external device is not flexible enough in the background art. The above-mentioned objects, features and advantages of the embodiments of the present invention will become more apparent and understood. The program is explained in further detail. Referring to Figure 1, there is shown a longitudinal cross-sectional view of an optoelectric composite cable system in accordance with an embodiment of the present invention. The optoelectronic composite cable system shown in FIG. 1 comprises an opto-electric composite cable 4 and at least one external module. The opto-electric composite cable has the same composition as the currently used opto-electric composite cable, and includes an optical cable, a live cable and a ground cable. The external module includes a housing 3, a PCB (Printed Circuit Board) 10, a first power take-off member, a second power take-off member, and a crimping plate 2. The housing 3 is the outer casing of the external module, providing a mounting base for the other components of the external module. Generally, the casing 3 may be made of ABS (Acrylonitri le Butadiene ene Styrene copolymers) material, or may be made of other kinds of hard materials. The casing 3 is a cavity structure with an open top end, and a slit is provided at both ends thereof, and the slit and the crimping plate 2 constitute a through hole 302 through which the photoelectric composite cable 4 passes. In this embodiment, the casing 3 may have a square structure or a ship structure. Preferably, the casing 3 has a ship-shaped structure, and the ship-shaped structure has a streamlined structure, facilitates wiring in a complicated environment such as a ceiling, and can avoid stress concentration when subjected to an external force, thereby reducing the probability of damage of the casing 3. The crimping plate 2 cooperates with the housing 3 to form a module cavity. During the actual operation, the opening and closing of the crimping plate 2 can open and close the cavity of the module. The crimping plate 2 may be made of an ABS material or may be made of other kinds of hard materials, and the present invention does not limit the material of the crimping plate 2. In the operation process of assembling the photoelectric composite cable and the external module, directly opening the crimping plate 2 to photoelectric composite The cable 4 is placed into the inner cavity of the module, and the portion of the optoelectronic composite cable 4 that protrudes from the external module is placed in the through hole 302, and then the crimping plate 2 is covered to fix the optical composite cable 4. In this embodiment, there are various ways in which the crimping plate 2 and the housing 3 are engaged. A manner of fitting the crimping plate 2 and the housing 3 is as follows: The crimping plate 2 is a piece, one side of the crimping plate 2 is hinged to the housing 3, and the other side of the crimping plate 2 passes through the housing 3 The buckle is snapped. Wherein one side is opposite to the other side. During the operation, the operator can realize the opening and closing of the crimping plate 2 by shaking or pressing, thereby realizing the quick and fixed connection between the photoelectric composite cable 4 and the external module. In this cooperation mode, the entire crimping plate 2 is closed to achieve compression of the photoelectric composite cable, and the entire photoelectric composite cable 4 is released when the crimping plate 2 is opened. In order to realize the operation of the external composite module under the pressed state, the crimping plate 2 in the embodiment is two pieces, and the two crimping plates 2 are assembled in the same manner as the housing 3, and both sides are The housing 3 is hinged, and the opposite side is engaged with the housing 3 by a snap. More preferably, the hinged sides of the two crimping plates 2 and the casing 3 are respectively located on opposite sides of the casing 3, and the structure can make the opening directions of the two crimping plates 2 opposite, and further When one of the crimping plates 2 is in a pressed state, the other crimping plate 2 is opened to operate the corresponding portion. At the same time, the above two crimping plates 2 can make the pressing force of the crimping plate 2 to the entire photoelectric composite cable 4 relatively balanced, and the stability of the pressing can be improved. The crimping plate 2 is connected to the housing 3 in a snap-fit manner. The card connection method can quickly and firmly realize the connection between the crimping plate 2 and the casing 3, thereby realizing quick and firm fixing of the photoelectric composite cable 4 and the external module. In the actual application process, in order to achieve a more secure fixing of the optoelectric composite cable 4, generally, the size of the crimping hole formed by the fixing of the casing 3 and the crimping plate 2 is slightly smaller than the outline size of the optoelectric composite cable 4. In order to further improve the connection stability of the external module and the optoelectric composite cable 4, the external module provided by the embodiment of the present invention further includes a cover plate 1, and two sides of the cover plate 1 and the two sides of the housing 3 are provided with mutually matching connecting members. The cover plate 1 is fixedly pressed to the outside of the crimping plate 2 by a connecting member. Specifically, the cover 1 can be a sliding cover. The manner of the cover 1 and the housing 3 can be as follows: The outer walls of the two sides of the housing 3 are provided with a recess 301, and the two sides of the cover 1 have grooves and grooves. 301 mating protrusion 102, at least one end of the recess 301 has an opening for the protrusion 102 to enter and exit, the protrusion 102 slides into the recess 301 to achieve a fixed connection between the cover plate 1 and the housing 3, and the cover plate 1 is disposed on the crimping plate 2 The outer side plays a better reinforcement role, and the problem of stability of connection between the external module and the optoelectric composite cable 4 is better solved. In order to facilitate the operation of the cover plate 1, the top surface of the cover plate 1 in this embodiment may be provided with a non-slip portion 101, such as a non-slip structure such as a non-slip groove, a non-slip projection. Of course, the crimping plate 2 and the housing 3 can also be carried out in other kinds of manners, for example, in the same manner as the cover 1 and the housing 3 are fitted. Since the cooperation of the protrusions and the grooves is relatively stable, the external module may not require the cover 1. At this time, the cooperation of the opto-electric composite cable 4 and the external module requires the operator to press hard, and then the crimping plate 2 is moved to achieve a fixed connection with the housing 3, which is compared with the crimping plate 2 and the housing 3. In the case of the card connection, the operation is inconvenient.

PCB板 10设置在模块内腔中。 通常， PCB板 10上设置有电子元器件以实现 外接模块的功能。 请再次参考附图 1， PCB板 10上设置有天线 11， 以实现信号的 发送或接收。 光电复合缆 4设置有外接光纤 8， PCB板 10上可以设置有与外接光 纤 8相连的光模块 7， 外接光纤 8与光模块 7相连形成光通路。 通常情况下， 外 接光纤 8与光模块 7的连接方式可以为在外接光纤 8的尾端研磨对接接头， 然后 冷接或热熔对接接头的方式， 外接光纤 8也可以通过光对接器 9辅助定位与光模 块 7相连。 第一取电件和第二取电件均与 PCB板 10电连接， 第一取电件与火线线缆相 对布置， 第二取电件与地线线缆相对布置。 压线板 2用于压紧光电复合缆 4以使 得第一取电件与火线线缆和第二取电件与地线线缆的金属内芯相接触以实现电 通路。 当外接模块包括盖板 1时， 优选的， 压线板 2紧贴于盖板 1面向模块内腔的 内表面上， 以实现盖板 1对压线板 2施加更为均衡、 且更为有效的压力。 同时， 压线板 2受盖板 1的压力更加有力地压紧光电复合缆 4， 以使第一取电件较稳定 地与火线线缆的金属内芯和第二取电件较为稳定地与地线线缆的金属内芯实现 电通路。 通过上述描述可知，光电复合缆 4的外接光纤 8与光模块 7连接实现光通路， 盖板 1的压力使得压线板 2压紧光电复合缆 4， 进而使得与火线线缆相对布置的 第一取电件和与地线线缆相对布置的第二取电件与各自对应的电缆的金属内芯 接触， 由于第一取电件和第二取电件与 PCB板 10均电连接， 进而第一取电件与 火线线缆和第二取电件与地线线缆的金属内芯接触实现了电通路。 可见， 外接光 纤 8与光模块 7相连、 第一取电件与火线线缆和第二取电件与地线线缆的金属内 芯接触最终实现了外接模块与光电复合缆的光电连接。 在实际的应用过程中，为了保证第一取电件和第二取电件准确地与光电复合 缆 4的相应位置的金属内芯接触， 光电复合缆 4的封塑外护套 41可以具有三个 相互隔离的线缆布设区， 分别为光缆区、 火线区和地线区。 相对应地， 光缆 42 设置在光缆区， 火线线缆 43设置在火线区， 地线线缆 44设置在地线区。 线缆布 设区的隔离分布能够使得光缆 42、火线线缆 43和地线线缆 44隔离分布， 进而避 免三种线缆之间的相互干扰。 而且， 这种隔离分布的方式能够解决第一取电件和 第二取电件无法准确地穿入电缆内取电的问题。 与此相对应的， 为了实现对上述 结构的光电复合缆 4实现更为稳定的压紧， 壳体 3上的穿孔 302与光电复合缆 4 的外形相吻合。 压线板 2具有与光电复合缆 4相适配的凹陷 201 (如图 4和图 2 所示）。 优选的， 火线线缆和地线线缆对称分布在光电复合缆 4 中光缆的两侧， 相对应地， 第一取电件和第二取电件分别设置在壳体 3的两侧。 本实施例中，第一取电件和第二取电件均可以在压力的作用下以剌入的方式 取电以实现电通路， 即第一取电件和第二取电件剌入到相对应的电缆中以实现与 线缆的金属内芯接触取电。 通常， 第一取电件和第二取电件均通过托盘固定在壳 体 3上， 且两者穿出托盘顶面的部位为剌入部， 剌入部用于穿入火线线缆或地线 线缆， 进而实现取电。 以图 2或图 4所示出的取电件作为第一取电件， 第一取电 件通过托盘 5固定在壳体 3上， 剌入部 12用于取电， 第一取电件的头端 6用于 与 PCB板 10电连接。 以图 1所示的取电件为第二取电件， 第二取电件通过托盘 13固定在壳体 3上、 剌入部 14用于取电， 第二取电件的头端 （图中未示出） 与 PCB板 10电连接。上述第一取电件和第二取电件的结构中， 托盘为第一取电件或 第二取电件的支撑部件， 第一取电件和第二取电件均与 PCB板 10 电连接， 从而 使得剌入部取电后与 PCB板 10 电连接。 第一取电件和第二取电件中， 一者剌入 火线线缆中取电后通过 PCB板 10后再通过另一者剌入地线线缆实现电通路。 为 了便于剌入部穿入火线线缆或地线线缆， 剌入部优选为取电探针或取电切刀。 为 了保证剌入部穿入后取电的准确性， 剌入部可以均为多个， 且沿火线线缆或地线 线缆的延伸方向成排布置。 请参考附图 19和 20， 第一取电件和第二取电件均可以在压力的作用下以夹 紧火线线缆和地线线缆的金属内芯的方式取电以实现电通路。 只不过此种方式在 操作的过程中需要操作人员需预先在与第一取电件、 第二取电件对应的位置， 将 火线线缆和地线线缆的外皮剥离， 裸露金属内芯。 通常， 第一取电件和第二取电 件均通过托盘固定在壳体 3上， 且两者穿出托盘顶面的部位为夹持部 15， 夹持部 15 用于夹紧火线线缆或地线线缆的金属内芯， 进而实现取电。 具体的， 夹持部 15可以为夹持夹片。图 19和图 20所示出的外接模块与图 3和图 4所示的外接模 块的区别仅在于夹持部 15和剌入部 12。 图 19和图 20所示的外接模块的其他结 构可参考本文其它部分的相关描述即可， 此不赘述。 当然， 本发明实施例中第一 取电件和第二取电件均可以为多个， 其中一些第一取电件和第二取电件穿出托盘 顶面的部位可以为剌入部 （例如探针或取电切刀）， 另一些第一取电件和第二取 电件穿出托盘顶面的部位可以为夹持部， 即剌入部和夹持部混合使用， 例如探针 与夹持夹片混合使用。 在外接模块的实际生产过程中， 连接部通常为刚性金属件。 托盘与 PCB 板 10之间的距离存在制造误差， 使得连接部的长度大于托盘和 PCB板 10之间的距 离， 最终导致连接部较难安装在托盘和 PCB板 10之间。 为此， 本发明实施例提 供第一取电件和第二取电件与 PCB板 10连接的头端具有用于调节连接长度的弹 簧探针。 弹簧探针通过伸缩实现第一取电件和第二取电件的头端伸缩， 进而改变 第一取电件和第二取电件连接长度的调整。 此种情况下， 即便托盘和 PCB 板 10 之间距离较小， 那么可以通过弹簧探针调整使得头端与 PCB板 10 电连接。 弹簧 探针使得第一取电件和第二取电件的头端成为具有伸缩功能的部件， 该种结构还 能够减小压线板 2在压紧光电复合缆的过程中连接部对 PCB板 10施加的作用力， 进而解决连接件对 PCB板 10施加较大的力而导致 PCB板 10上的电子元器件容易 损坏的问题。 通过本实施例的介绍可知，本实施例提供的外接模块与光电复合缆 4相连的 过程中， 打开压线板 2后压紧压线板 2， 实现第一取电件和第二取电件分别与光 电复合缆 4的火线线缆和地线线缆的金属内芯接触以实现取电， 此之前操作人员 连接外接光纤与光模块相连实现光通路。 上述取电方式方便了取电， 简化了取电 接线， 最终能够提高接线效率， 能够解决背景技术中外接设备和光电复合缆连接 效率低的问题。 本实施例提供的外接模块能够与光电复合缆 4固定在一起，使得外接模块直 接依附于光电复合缆 4的外部，使之与光电复合缆 4相对固定，无需额外的固定装置， 减少占用空间。外接模块依附于光电复合缆 4之后，操作人员可通过打弯或盘置光电 复合缆 4的方式来微调外接模块位置以达到更好的使用效果，即通过调整光电复合缆 4即可调整外接模块的位置， 可方便局部优化使用效果。 同时， 外接光纤 8可以形成 于光电复合缆 4的任意位置， 而且可以根据需求调整外接光纤 8的外伸长度。现场施 工人员能够根据施工现场的设计合理地确定外接光纤 8的位置和长度，进而适用于各 种复杂的现场接线环境。可见，本发明提供的外接模块能够提高光电复合缆 4与外接 设备连接的灵活性， 最终能够解决外接设备位置设置或变动不够灵活的问题。 为了保证第一取电件和第二取电件较准确地与光电复合缆 4 的电缆的金属 内芯接触， 请参考附图 5， 图 5示出了本发明实施例提供的光电复合缆的第一种 结构。图 5所示的光电复合缆与普通的光电复合缆组成相同，包括封塑外护套 41、 光缆 42、 火线线缆 43和地线线缆 44。 封塑外护套 41是整个光电复合缆的外围 防护部件， 用于保护火线线缆 43、 地线线缆 44和光缆 42。 封塑外护套 41是将 火线线缆 43、 地线线缆 44和光缆 42集成为一体式线缆的外围连接部件。 通常， 封塑外护套 41可以采用 PVC ( Polyvinyl chloride , 聚氯乙烯）材料、 LSZH ( Low Smoke Zero Halogen , 低烟无卤） 材料或 PE ( po lyethylene , 聚乙烯） 材料制成。 当然， 封塑外护套 41 还可以采用其它可用于制作线缆护套的材料制作， 本实施 例不对封塑外护套 41的材质作限制。 图 5所示的光电复合缆中， 封塑外护套 41 具有三个相互隔离的线缆布设区， 分别为光缆区、 火线区和地线区。 相对应地， 光缆 42设置在光缆区， 火线线缆 43设置在火线区， 地线线缆 44设置在地线区。 线缆布设区的隔离分布能够使得光缆 42、 火线线缆 43和地线线缆 44隔离分布， 进而避免三种线缆之间的相互干扰。 而且， 这种隔离分布的方式能够解决第一取 电件和第二取电件无法准确地与光电复合缆内电缆的金属内芯接触取电的问题。 图 5所示的光电复合缆中， 光缆区、火线区和地线区的中心线位于同一平面 内， 且光缆区位于火线区和地线区之间。 优选的， 火线区和地线区对称分布在光 缆区的两侧。 通常情况， 光缆区的外部尺寸大于火线区和地线区的外部尺寸， 且 火线区和地线区外部尺寸相等 （外部尺寸指的是外部轮廓的最大尺寸）。 火线区 和地线区对称分布在光缆区的两侧， 这能够起到平衡光缆两侧拉力的作用， 进而 使得光缆两侧的拉拽移动速度相等或差别较小， 最终保证光电复合缆在拉拽行进 的封塑过程中， 光缆两侧的封塑厚度较均匀。 这能够提高光电复合缆的质量。 而 且， 本发明提供的光电复合缆采用区域隔离的布局使得两条相对独立的电缆既可 以起到加强筋的作用， 又不会把自身的扭力传递到相对脆弱的光纤上。 火线线缆 43和地线线缆 44的结构可以相同， 此种情况下， 两者的外皮可以 设置与各自相对应的电缆标识。 电缆标识用于区分火线线缆 43和地线线缆 44， 进而降低电缆的误接率。 电缆标识可以为文字标识或颜色标识 （例如火线线缆的 外皮为红色， 地线线缆的外皮为黑色）。 为了便于操作人员直观识别， 电缆标识 优选设置在封塑外护套 41外表面与火线线缆 43和地线线缆 44相对应的部位。 为了满足传输大量信息的需求， 光缆 42 通常包含很多根光纤。 这会导致封塑外 护套 41与光缆 42相对应部位的外部尺寸大于封塑外护套 41与火线线缆 43和地 线线缆 44相对应部位的外部尺寸。 此种情况下， 电缆标识能够区分地线线缆 44 和火线线缆 43即可， 地线线缆 44和火线线缆 43通过外部尺寸即可区别于光缆 42。 如果火线线缆 43、 地线线缆 44及光缆 42与封塑外护套 41相对应部位在外 观上无区别 （即三个相对部位的外部尺寸相等或相当）， 这不仅导致电缆的误接 率较高， 而且还会导致光缆的误接率较高。 为此， 电缆标识还应该具有能够将火 线线缆 43和地线线缆 44与光缆 42区分开的功能。 火线线缆 43和地线线缆 44均可以包括铜芯电线 431和绝缘护套 432。 绝缘 护套 432包覆于铜芯电线 431外， 用于绝缘隔离铜芯电线 431。火线线缆 43和地 线线缆 44还可以采用其它种类的金属内芯线， 并不局限于铜芯电线。 绝缘护套 432可以由 PVC材料、 LSZH材料或 PE材料制作。 本实施例中， 一种具体的火线 线缆 43或地线线缆 44的结构如下： 铜芯电线 431采用 2. 5方铜芯电线， 绝缘护 套 432的外径为 3. 6mm 0在实际的设计时，铜芯电线 431的平方数与绝缘外套 432 的外部尺寸一一对应， 并不限于上述尺寸。 本实施例中， 光缆 42包括紧套光纤和紧套光纤外皮 423。 紧套光纤是一种 类型的光纤， 是对光纤进行保护后形成的一种常用光纤。 本实施例中的紧套光纤 为单芯紧套光纤 421。 通常情况， 单芯紧套光纤 421 的标准外径为 0. 9mm。 紧套 光纤外皮 423用于保护单芯紧套光纤 421， 其可以采用 PVC材料、 LSZD材料或 PE 材料。 根据行业内部标准， 紧套光纤外皮 423的厚度通常为 2mm。 为了提高光缆 的抗拉性能， 光缆 42还可以包括抗拉增强层 422， 抗拉增强层 422填充于单芯紧 套光纤 421和紧套光纤外皮 423之间。 抗拉增强层 422可以为芳纶纱制成的芳纶 纱层或玻璃纱制成的玻璃纱层。 本实施例不对抗拉增强层 422的材质作限制。本实施例中光缆的单芯紧套光 纤 421至少有一根作为引出光纤用于与外接模块的光模块相连。 本实施例提供的 光电复合缆 4中， 单芯紧套光纤 421至少有一根作为引出光纤， 引出光纤从光电 复合缆的内部引出于封塑外护套 41 之外， 用于连接外接模块。 为了实现引出光 纤的引出， 封塑外护套 41 与光缆区相对的部位设置有用于截断引出光纤的截断 口和与截断口间隔设定距离设置的， 用于抽出引出光纤的光纤抽出切口。 本实施 例中截断口和光纤抽出切口可以为横向切口 （即沿着光电复合缆的径向）， 也可 以为纵向切口 （即沿着光电复合缆的延伸方向）， 当然， 截断口和光纤抽出切口 也可以为介于横向切口和纵向切口的斜切口。 在制作光电复合缆的过程中，在任意位置将封塑外护套 41切开形成截断口， 然后在保持抗拉增强层 422完整的情况下通过截断口将引出光纤截断， 再之后在 截断口设定距离处将封塑外护套 41 切开形成光纤抽出切口， 用于将截断后的引 出光纤抽出。 引出光纤被截断后形成前端光纤和后端光纤。 其中， 前端光纤是引 出光纤与信号源连接的一段光纤， 后端光纤是引出光纤除去前端光纤后剩下的一 段光纤。 前端光纤通过光纤抽出切口被抽出， 用于形成可与外接模块的光模块 7 连接的外接光纤。 截断口和光纤抽出切口是引出光纤被引出的必要条件， 两者由 于破坏封塑外护套 41 的完整性会使得光电复合缆的防水防尘性能下降。 为此， 本实施例提供的光电复合缆 4还可以包括设置在截断口的截断口防护套和光纤抽 出切口的抽出切口防护套。 截断口防护套和抽出切口防护套可以为集成于一体的 一体式结构， 也可以为分体式结构。 当然， 上述截断口和光纤抽出切口在完成截 断与抽出光纤的之后即可用防护套防护， 也可以用其它工艺手段 （例如胶带、 胶 等粘结工艺） 封闭以用于防护。 优选的， 截断口与光纤抽出切口可以为连续切断 而形成的一条切口， 便于操作。 在后续使用时， 外接光纤可以通过尾纤冷接或热熔对接的方式与外接模块的 光模块相连以形成光通路， 也可以通过尾纤冷接或热熔连接光纤连接法兰， 然后 通过光纤连接法兰对接的方式与外接模块的光模块 7相连以形成光通路。 第一取 电件和第二取电件分别剌入光电复合缆 4两侧的电缆中，最终实现光电复合缆 4与外 接模块形成电通路。 光电复合缆 4与外接模块连接后可以利用外接模块的外壳 3或单独的防护外壳 代替截断口防护套和抽出切口防护套来对光电复合缆进行防护。 引出光纤形成外接光纤的方式有很多种，下面结合附图 6-8所示的几种方式 进行示例性地详细说明。 请参考附图 6， 图 6示出的是图 5所示的光电复合缆采用集束直通应用模式 的结构。 所谓集束直通应用模式指的是每根引出光纤截断后形成的前端光纤 45 分别直接对接一个外接模块， 每根引出光纤对应的光纤抽出切口的数量为一个， 且光纤抽出切口和截断口均位于前端光纤 45与封塑外护套 41相对应的部位上， 前端光纤 45 被抽出后作为外接光纤与外接模块相连。 此种模式下， 引出光纤被 截断后， 前端光纤 45 进行了利用， 后端光纤则被弃用。 此种模式较适用于具有 较多根单芯紧套光纤 421的光电复合缆。优选的方案中， 引出光纤的前端光纤 45 自光纤抽出切口穿出的部位附着在封塑外护套 41 的表面。 本实施例中， 封塑外 护套 41与光缆区和火线区相对的部位之间， 以及封塑外护套 41与光缆区和地线 区相对的部位之间均形成沟槽 A， 前端光纤 45贴附在沟槽 A中， 以实现对引出光 纤更好的布置， 能够避免对外接光纤的损坏。 更为优选的， 本实施例中的光电复 合缆 4还包括将引出光纤穿出光纤抽出切口部位固定于沟槽的固定部。 例如前端光 纤 45可以通过防护塑料薄膜或防护胶布缠固在封塑外护套 41上， 也可以通过防 护胶粘固在封塑外护套 41上。 本实施例可以在光电复合缆 4 的其它不同位置分别取出不同的单芯紧套光纤 421作为引出光纤， 并进行相同的操作后形成与外接模块连接的外接光纤。 为了提高光电复合缆的防尘防水性能，图 6所示的光电复合缆还可以包括设 置在截断口的截断口防护套 46和光纤抽出切口的抽出切口防护套 47。 截断口防 护套 46和抽出切口防护套 47可以为一体式结构， 也可以为分体式结构 （如图 6 所示）。 请参考附图 7，图 7示出的是图 5所示的光电复合缆采用分布分路应用模式的结 构。在光电复合缆

Generally, electronic components are disposed on the PCB 10 to implement the functions of the external modules. Referring again to FIG. 1, the PCB 11 is provided with an antenna 11 for signal transmission or reception. The optical composite cable 4 is provided with an external optical fiber 8. The optical circuit 7 can be connected to the external optical fiber 8 on the PCB. The external optical fiber 8 is connected to the optical module 7 to form an optical path. Generally, the connection mode of the external optical fiber 8 and the optical module 7 may be a method of grinding the butt joint at the tail end of the external optical fiber 8, and then cold-bonding or hot-melt the butt joint, and the external optical fiber 8 may also be assisted by the optical docking device 9. It is connected to the optical module 7. The first power take-off member and the second power take-off member are electrically connected to the PCB board 10. The first power take-off member is disposed opposite to the live wire cable, and the second power take-off member is disposed opposite to the ground wire cable. The crimping plate 2 is used to press the optoelectric composite cable 4 such that the first power take-off member and the live wire and the second power take-off member are in contact with the metal inner core of the ground wire to realize an electrical path. When the external module includes the cover plate 1, preferably, the crimping plate 2 is in close contact with the inner surface of the cover plate 1 facing the inner cavity of the module, so that the cover plate 1 exerts a more balanced and more effective application to the crimping plate 2. pressure. At the same time, the crimping plate 2 is pressed more strongly by the pressure of the cover plate 1 to make the first power take-off member more stable with the metal inner core and the second power take-off member of the live wire cable. The metal core of the ground cable realizes an electrical path. It can be seen from the above description that the external optical fiber 8 of the optoelectric composite cable 4 is connected to the optical module 7 to realize the optical path, and the pressure of the cover plate 1 causes the crimping plate 2 to press the optical composite cable 4, thereby making the first arrangement opposite to the live cable. The power take-off member and the second power take-off member disposed opposite to the ground cable are in contact with the metal core of the corresponding cable, and the first power take-off member and the second power take-off member are electrically connected to the PCB board 10, and further An electrical path is achieved by contacting a power take-off with the live wire and the second power take-off to the metal core of the ground wire. It can be seen that the external optical fiber 8 is connected to the optical module 7, and the first power take-off component and the live power cable and the second power take-off component are in contact with the metal inner core of the ground cable to finally realize the photoelectric connection between the external module and the photoelectric composite cable. In the actual application process, in order to ensure that the first power take-off and the second power take-off are accurately combined with the photoelectric The metal inner core of the corresponding position of the cable 4 is in contact, and the plastic outer sheath 41 of the photoelectric composite cable 4 may have three mutually isolated cable routing areas, which are a cable area, a fire line area and a ground line area, respectively. Correspondingly, the optical cable 42 is disposed in the cable area, the live wire 43 is disposed in the live line area, and the ground cable 44 is disposed in the ground line. The isolation distribution of the cable routing area enables the optical cable 42, the live cable 43 and the ground cable 44 to be isolated, thereby avoiding mutual interference between the three cables. Moreover, the manner of the isolation distribution can solve the problem that the first power take-off member and the second power take-off member cannot accurately penetrate into the cable to take power. Correspondingly, in order to achieve a more stable compression of the optoelectric composite cable 4 of the above structure, the perforations 302 on the casing 3 coincide with the outer shape of the optoelectric composite cable 4. The crimping plate 2 has a recess 201 (shown in Figures 4 and 2) that is adapted to the optoelectric composite cable 4. Preferably, the live wire cable and the ground wire cable are symmetrically distributed on both sides of the optical cable in the photoelectric composite cable 4, and correspondingly, the first power take-off member and the second power take-off member are respectively disposed on both sides of the casing 3. In this embodiment, the first power take-off member and the second power take-off member can be powered by the force of the power to realize the electrical path, that is, the first power take-off member and the second power take-off member are inserted into the device. Corresponding to the cable to achieve electrical contact with the metal core of the cable. Generally, the first power take-off member and the second power take-off member are both fixed to the casing 3 through the tray, and the portions of the two that pass through the top surface of the tray are the intrusion portions, and the intrusion portion is used to penetrate the live wire or the ground wire. Cable, and then achieve power. The power take-off member shown in FIG. 2 or FIG. 4 is used as the first power take-off member, and the first power take-off member is fixed on the casing 3 through the tray 5, and the plunging portion 12 is used for taking power, and the head of the first power take-off member The terminal 6 is for electrical connection with the PCB board 10. The power take-off member shown in FIG. 1 is the second power take-off member, the second power take-off member is fixed on the casing 3 through the tray 13, and the plunging portion 14 is used for taking power, and the head end of the second power take-off member (in the figure) Not shown) is electrically connected to the PCB board 10. In the structure of the first power take-off member and the second power take-off member, the tray is a support member of the first power take-off member or the second power take-off member, and the first power take-off member and the second power take-off member are electrically connected to the PCB board 10 The connection is such that the intrusion portion is electrically connected to the PCB board 10 after being powered. One of the first power take-off member and the second power take-off member is electrically connected to the live wire cable and then passed through the PCB board 10 and then the ground wire is passed through the other to realize the electrical path. In order to facilitate the penetration of the firewire cable or the ground cable by the intrusion portion, the intrusion portion is preferably a power take-off probe or a power take-off knife. In order to ensure the accuracy of the power take-off after the penetration portion is inserted, the intrusion portions may be plural and arranged in a row along the extending direction of the live wire or the ground cable. Referring to Figures 19 and 20, both the first power take-off member and the second power take-off member can be energized by clamping the metal core of the live wire and the ground cable to achieve an electrical path. However, in this way, the operator needs to peel off the outer skin of the live wire and the ground cable in advance at the position corresponding to the first power take-off member and the second power take-off member, and expose the metal inner core. Generally, the first power take-off member and the second power take-off member are both fixed to the casing 3 through the tray, and the portions of the two that pass through the top surface of the tray are the clamping portion 15 and the clamping portion. 15 Used to clamp the metal core of the live wire or ground cable to achieve power. Specifically, the clamping portion 15 can be a clamping clip. The external module shown in Figs. 19 and 20 differs from the external module shown in Figs. 3 and 4 only in the holding portion 15 and the plunging portion 12. For other structures of the external modules shown in FIG. 19 and FIG. 20, reference may be made to related descriptions of other parts of the present document, and details are not described herein. Certainly, in the embodiment of the present invention, the first power take-off component and the second power take-off component may be multiple, and some of the first power take-off component and the second power take-off component may be the intrusion part of the top surface of the tray (for example, The probe or the electric cutter), the other parts of the first power take-off and the second power take-off that pass through the top surface of the tray may be a clamping portion, that is, a combination of the plunging portion and the clamping portion, such as a probe and a clip. Hold the clips together. In the actual production of the external module, the connection is usually a rigid metal part. There is a manufacturing error in the distance between the tray and the PCB 10 such that the length of the connection is larger than the distance between the tray and the PCB 10, eventually resulting in the connection being more difficult to mount between the tray and the PCB 10. To this end, the embodiment of the present invention provides that the head end of the first power take-off member and the second power take-off member connected to the PCB board 10 has a spring probe for adjusting the length of the connection. The spring probe realizes the expansion and contraction of the head ends of the first power take-off member and the second power take-off member by telescopic expansion, thereby changing the connection length of the first power take-off member and the second power take-off member. In this case, even if the distance between the tray and the PCB 10 is small, the tip end can be electrically connected to the PCB 10 by spring probe adjustment. The spring probe makes the head end of the first power take-off member and the second power take-off member into a telescopic function component, and the structure can also reduce the connection portion to the PCB board of the crimping plate 2 in the process of pressing the photoelectric composite cable The applied force of 10 further solves the problem that the connecting member applies a large force to the PCB board 10 to cause the electronic components on the PCB board 10 to be easily damaged. According to the introduction of the embodiment, in the process of connecting the external module provided by the embodiment to the optoelectric composite cable 4, the crimping plate 2 is opened, and the crimping plate 2 is pressed to realize the first power take-off member and the second power take-off member. The power is connected to the metal core of the live cable of the optoelectronic composite cable 4 and the ground cable to realize power supply. Before this, the operator connects the external fiber to the optical module to realize the optical path. The above power-taking mode facilitates power taking, simplifies the power take-off wiring, and finally improves the wiring efficiency, and can solve the problem of low connection efficiency of the external device and the photoelectric composite cable in the background art. The external module provided in this embodiment can be fixed together with the opto-electric composite cable 4, so that the external module directly attaches to the outside of the opto-electric composite cable 4, so as to be relatively fixed with the opto-electric composite cable 4, and no additional fixing device is needed, thereby reducing the occupied space. After the external module is attached to the photoelectric composite cable 4, the operator can finely adjust the position of the external module by bending or arranging the photoelectric composite cable 4 to achieve better use effect, that is, adjusting the external module by adjusting the photoelectric composite cable 4. The location can be easily optimized for local use. At the same time, the external optical fiber 8 can be formed At any position of the optoelectric composite cable 4, the outer elongation of the external optical fiber 8 can be adjusted as needed. The on-site construction personnel can reasonably determine the position and length of the external fiber 8 according to the design of the construction site, and is suitable for various complicated field wiring environments. It can be seen that the external module provided by the present invention can improve the flexibility of the connection of the opto-electric composite cable 4 and the external device, and finally can solve the problem that the position setting or the variation of the external device is not flexible enough. In order to ensure that the first power take-off member and the second power take-off member are in contact with the metal core of the cable of the photoelectric composite cable 4, please refer to FIG. 5, which shows the photoelectric composite cable provided by the embodiment of the present invention. The first structure. The optoelectric composite cable shown in FIG. 5 has the same composition as a conventional opto-electric composite cable, and includes a molded outer sheath 41, a fiber optic cable 42, a live wire 43 and a ground cable 44. The molded outer sheath 41 is a peripheral protective member of the entire optoelectric composite cable for protecting the live wire 43, the ground cable 44, and the cable 42. The molded outer sheath 41 is a peripheral connecting member that integrates the live wire cable 43, the ground cable 44, and the optical cable 42 into an integrated cable. Generally, the outer jacket 41 can be made of PVC (Polyvinyl chloride), LSZH (Low Smoke Zero Halogen) or PE (Po lyethylene). Of course, the outer jacket 41 can also be made of other materials that can be used to make the cable sheath. This embodiment does not limit the material of the outer jacket 41. In the optoelectric composite cable shown in FIG. 5, the outer sheath 41 has three cable-separating regions which are isolated from each other, and are respectively a cable region, a firewire region and a ground region. Correspondingly, the optical cable 42 is disposed in the cable area, the live wire 43 is disposed in the live line region, and the ground cable 44 is disposed in the ground line. The isolation distribution of the cable routing area enables the optical cable 42, the live cable 43 and the ground cable 44 to be isolated, thereby avoiding mutual interference between the three cables. Moreover, the manner of the isolation distribution can solve the problem that the first power take-off member and the second power take-off member cannot accurately contact the metal inner core of the cable in the photoelectric composite cable. In the optoelectric composite cable shown in Fig. 5, the center line of the cable area, the live line area and the ground line area are located in the same plane, and the cable area is located between the live line area and the ground line area. Preferably, the live line area and the ground line area are symmetrically distributed on both sides of the cable area. Typically, the outer dimensions of the cable section are larger than the outer dimensions of the live zone and the ground zone, and the outer dimensions of the live zone and the ground zone are equal (the outer dimension refers to the largest dimension of the outer profile). The fire line area and the ground line area are symmetrically distributed on both sides of the cable area, which can balance the pulling force on both sides of the cable, so that the moving speed of the pulling on both sides of the cable is equal or small, and finally the photoelectric composite cable is pulled. During the sealing process of the crucible, the thickness of the sealing on both sides of the cable is relatively uniform. This can improve the quality of the optoelectric composite cable. Moreover, the optoelectronic composite cable provided by the present invention adopts a regionally isolated layout such that two relatively independent cables can function as reinforcing ribs without transmitting their own torque to the relatively fragile optical fibers. The structure of the live wire 43 and the ground cable 44 may be the same, in which case the outer skins of the two may be provided with respective cable identifications. The cable identification is used to distinguish the live cable 43 from the ground cable 44. In turn, the cable misconnection rate is reduced. The cable identification can be a text mark or a color mark (for example, the outer skin of the live wire is red, and the outer surface of the ground cable is black). In order to facilitate visual recognition by the operator, the cable identification is preferably provided at a portion of the outer surface of the molded outer sheath 41 corresponding to the live wire 43 and the ground cable 44. To meet the need to transfer large amounts of information, fiber optic cable 42 typically contains a number of fibers. This causes the outer dimension of the portion of the outer sheath 41 and the cable 42 to be larger than the outer dimension of the portion of the outer sheath 41 and the live cable 43 and the ground cable 44. In this case, the cable identification can distinguish between the ground cable 44 and the live cable 43, and the ground cable 44 and the live cable 43 can be distinguished from the cable 42 by external dimensions. If the corresponding parts of the live wire cable 43, the ground cable 44, and the optical cable 42 and the outer sheath 41 are indistinguishable (that is, the outer dimensions of the three opposite portions are equal or equivalent), this not only causes misconnection of the cable. The rate is higher, and it also leads to a higher misconnection rate of the cable. To this end, the cable identification should also have the ability to distinguish the live cable 43 and the ground cable 44 from the cable 42. Both the live wire 43 and the ground cable 44 may include a copper core wire 431 and an insulating sheath 432. The insulating sheath 432 is wrapped around the copper core wire 431 for insulating the isolated copper core wire 431. The firewire cable 43 and the ground cable 44 may also be of other types of metal core wires, and are not limited to copper core wires. The insulating sheath 432 can be made of a PVC material, a LSZH material, or a PE material. I. The actual outer diameter of the insulating sheath 432 is 3. 6mm 0 in practice. The outer diameter of the insulating sheath 432 is 3. 6mm 0 in practice. In the design, the number of squares of the copper core wires 431 is in one-to-one correspondence with the outer dimensions of the insulating jacket 432, and is not limited to the above dimensions. In this embodiment, the optical cable 42 includes a tight-fitting optical fiber and a tight-fitting optical fiber sheath 423. A tight-fitting fiber is a type of fiber that is a common fiber formed by protecting an optical fiber. The tight-fitting optical fiber in this embodiment is a single-core tight-fitting optical fiber 421. 9毫米。 The standard outer diameter of the single-core tight-fitting optical fiber 421 is 0. 9mm. The tight-fitting optical fiber sheath 423 is used to protect the single-core tight-fitting optical fiber 421, which may be made of PVC material, LSZD material or PE material. According to industry internal standards, the thickness of the tight fiber sheath 423 is typically 2 mm. In order to improve the tensile properties of the cable, the cable 42 may further include a tensile reinforcement layer 422 that is filled between the single-core sleeve fiber 421 and the tight-foil fiber sheath 423. The tensile reinforcing layer 422 may be an aramid yarn layer made of aramid yarn or a glass yarn layer made of glass yarn. This embodiment does not limit the material of the tensile reinforcement layer 422. In this embodiment, at least one of the single-core tight-fitting optical fibers 421 of the optical cable is used as an outgoing optical fiber for connecting to the optical module of the external module. In the optoelectric composite cable 4 provided in this embodiment, at least one of the single-core tight-fitting optical fibers 421 is used as the lead-out optical fiber, and the lead-out optical fiber is led from the inside of the opto-electric composite cable to the outer sheath 41 for connecting the external module. In order to achieve the light The fiber is taken out, and the outer portion of the sealed outer sheath 41 opposite to the cable area is provided with a cut-off port for cutting off the lead-out optical fiber and a set distance separating from the cut-off port, and an optical fiber extraction slit for extracting the lead-out optical fiber. In this embodiment, the cut-off port and the fiber extraction slit may be a transverse slit (ie, along the radial direction of the photoelectric composite cable), or may be a longitudinal slit (ie, along the extending direction of the optoelectric composite cable). Of course, the cut-off port and the optical fiber are extracted. The incision may also be a beveled incision between the transverse incision and the longitudinal incision. In the process of fabricating the photoelectric composite cable, the outer sheath 41 is cut at any position to form a cut-off port, and then the lead-out fiber is cut through the cut-off port while keeping the tensile reinforcement layer 422 intact, and then at the cut-off port. The sealed outer sheath 41 is cut at a set distance to form an optical fiber extraction slit for extracting the cut-out lead fiber. The lead fiber is cut off to form a front end fiber and a back end fiber. The front end fiber is a length of fiber that connects the fiber to the signal source, and the back fiber is a piece of fiber that is left after the fiber is removed to remove the front fiber. The front end fiber is extracted through the fiber extraction cutout to form an external fiber that can be connected to the optical module 7 of the external module. The cut-off port and the fiber-drawn cutout are necessary conditions for the lead-out of the optical fiber to be led out, and both of them deteriorate the waterproof and dustproof performance of the photoelectric composite cable due to the destruction of the integrity of the outer sheath 41. To this end, the optoelectric composite cable 4 provided in this embodiment may further include a cut-off protection cover disposed at the cut-off port and an extraction slit guard sleeve for extracting the optical fiber. The cut-off protective cover and the extracted cut-out protective cover may be integrated or integrated, or may be a split structure. Of course, the above-mentioned cut-off port and the fiber-extracting slit can be protected by a protective sleeve after the cutting and extracting of the optical fiber is completed, or can be closed by other processes (for example, a bonding process such as tape or glue) for protection. Preferably, the cut-off port and the fiber extraction slit may be a slit formed by continuous cutting, which is convenient for operation. In the subsequent use, the external fiber can be connected to the optical module of the external module through the pigtail cold-bonding or hot-melt docking to form an optical path, or the fiber can be connected by a pigtail cold-bond or hot-melt connection, and then through the fiber. The connection flange is connected in a manner to the optical module 7 of the external module to form an optical path. The first power take-off member and the second power take-off member are respectively inserted into the cables on both sides of the photoelectric composite cable 4, and finally the photoelectric composite cable 4 and the external module form an electrical path. After the photoelectric composite cable 4 is connected with the external module, the photoelectric composite cable can be protected by using the outer casing 3 of the external module or a separate protective casing instead of the cut-off protective cover and the extraction slit protective sleeve.

For example, the branch fiber 4111 may be affixed to the outer sheath 41 by a protective plastic film or a protective tape, or may be adhered to the outer sheath 41 by a protective adhesive. The distributed shunt application mode can also perform the same operation on the same root lead-out fiber 413 at other different locations of the optoelectric composite cable. Of course, the number of times the same outgoing fiber is externally connected is related to the receiving sensitivity and the docking loss of the optical module of the external module, and is not infinite.

Referring to FIG. 10, FIG. 10 shows a photoelectric composite cable of a third structure according to an embodiment of the present invention. The optoelectric composite cable 4 shown in Fig. 10 may further include a plurality of reinforcing cords 419 which are discretely distributed between the plurality of single-core sleeve fibers 421 to improve the tensile properties of the entire optoelectric composite cable.

Typically, the outer dimensions of the cable section are larger than the outer dimensions of the live zone and the ground zone, and the outer dimensions of the live zone and the ground zone are equal. The fire line area and the ground line area are symmetrically distributed on both sides of the cable area, which can balance the pulling force on both sides of the cable 42, so that the moving speed of the pulling on both sides of the cable 42 is equal or small, and finally the photoelectric composite cable is guaranteed. During the sealing process of pulling the raft, the thickness of the sealing on both sides of the cable is relatively uniform, which can improve the quality of the photoelectric composite cable. The opto-electric composite cable shown in FIG. 15 is only different from the distribution of the optical cable, the live wire and the ground wire in the aforementioned opto-electric composite cable. Please refer to FIGS. 16, 17, and 18 together. FIGS. 16-18 are different ways of drawing the optical fiber to form the external optical fiber.
