Description
技术领域technical field
本发明属于光缆技术领域，尤其是涉及一种光电混合缆。The invention belongs to the technical field of optical cables, in particular to a photoelectric hybrid cable.
背景技术Background technique
随着4G网络、光纤到户、光纤到楼的发展，光纤光缆的需求量日益增长。然而，人们在希望光信号入户的同时，将电力一起提拱，这样更便于使用、使用户的成本更低。为此，国内外出现了多种结构的光电混合缆，如公开号为CN103325471A的专利公开了一种新型光电混合缆，它包括中心加强件（1）、光缆（2）、屏蔽电源线（3）、阻水带（4）和阻燃护套（5），阻燃护套（5）内部设置有阻水带（4），阻水带（4）内设置有至少一根光缆（2）、中心加强件（1）和多根屏蔽电源线（3），屏蔽电源线包括铜芯（7）、绝缘层（8）、屏蔽层（9）和护套（10），铜芯（7）位于屏蔽电源线（3）的中心，铜芯（7）外围依次设有绝缘层（8）、屏蔽层（9）和护套（10），中心加强件（1）位于阻燃护套（5）的中心处，光缆（2）和屏蔽电源线（3）均匀分布于中心加强件（1）与阻水带（4）形成的密闭空间内；这种复合缆的柔软性相对较差，并不能达到优良的抗反复弯曲的性能。With the development of 4G network, fiber-to-the-home, and fiber-to-the-building, the demand for fiber optic cables is increasing. However, when people hope that the optical signal can enter the home, the power will be provided together, which is more convenient to use and lowers the cost of the user. For this reason, the photoelectric hybrid cable of various structures has appeared at home and abroad, discloses a kind of novel photoelectric hybrid cable as the patent of publication number CN103325471A, and it comprises central reinforcement (1), optical cable (2), shielded power cord (3 ), a water-blocking tape (4) and a flame-retardant sheath (5), the flame-retardant sheath (5) is provided with a water-blocking tape (4), and the water-blocking tape (4) is provided with at least one optical cable (2) , a central reinforcement (1) and a plurality of shielded power cables (3), the shielded power cable includes a copper core (7), an insulating layer (8), a shielding layer (9) and a sheath (10), a copper core (7) Located in the center of the shielded power line (3), the copper core (7) is provided with an insulating layer (8), a shielding layer (9) and a sheath (10) in sequence, and the central reinforcement (1) is located in the flame-retardant sheath (5 ), the optical cable (2) and the shielded power cable (3) are evenly distributed in the enclosed space formed by the central reinforcement (1) and the water blocking tape (4); the flexibility of this composite cable is relatively poor, and Excellent resistance to repeated bending cannot be achieved.
再如公开号为CN103366893A的专利公开了一种4G用馈线型光电混合缆，包括电缆外护套，所述电缆外护套包括绕包层（1），在所述绕包层（1）外设有铝焊接扎纹层（2），在所述铝焊接扎纹层（2）外设有外护层（3），在所述绕包层（1）内设有两组电单元（4）、两组光单元（5）和填充（6），所述电单元（4）和光单元（5）围绕填充（6）间或设置。这种结构由于光单元分开设置，故不易接续。Another example is that the patent with the publication number CN103366893A discloses a 4G feeder-type photoelectric hybrid cable, which includes a cable outer sheath, and the cable outer sheath includes a wrapping layer (1), and outside the wrapping layer (1) An aluminum welding ply layer (2) is provided, an outer sheath (3) is provided outside the aluminum welding ply layer (2), and two sets of electrical units (4) are provided inside the wrapping layer (1) ), two groups of light units (5) and filling (6), the electric unit (4) and light unit (5) are occasionally arranged around the filling (6). This structure is not easy to be connected because the light units are arranged separately.
另外，上述文献公开的混合缆，电单元、光单元放在一起且没有有效的隔热措施。由于光纤使有温度极其有限，故使得电单元发热后，影响光信号的传输性能，使光纤的衰减显著增加，达到70度时，信号传输受阻，严重影响了通信。In addition, in the hybrid cable disclosed in the above document, the electric unit and the optical unit are put together without effective heat insulation measures. Due to the extremely limited temperature of the optical fiber, the electric unit is heated, which affects the transmission performance of the optical signal and significantly increases the attenuation of the optical fiber. When it reaches 70 degrees, the signal transmission is blocked, which seriously affects the communication.
