Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a composite cable. Background Technology

[0002] Composite cables are cables that combine multiple different types of cables, typically including power cables, communication cables, and control cables. They can simultaneously meet multiple functional requirements. Composite cables are usually composed of conductors made of two or more different materials and typically include insulation layers, sheaths, shielding layers, and core wires. Among them, optical fiber composite cables are a typical example of composite cables, integrating optical fiber and copper cable to transmit both optical and electrical signals.

[0003] In the prior art, the structure of composite cables usually consists of two parts: the cable core and the sheath. The cable core usually includes a conductor for transmitting electrical signals and an optical fiber for transmitting optical signals. Since the conductor and optical fiber cores are both wrapped inside the sheath, when the conductor is damaged due to current problems, the leakage current generated by the damaged conductor can easily cause damage to the nearby optical fiber. Therefore, a composite cable is proposed to solve the above problems. Utility Model Content

[0004] This utility model mainly provides a composite cable to prevent power line leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a composite cable, comprising: an optical fiber core, a power core, a filler rope and a reinforcing core, wherein a base sleeve is provided on the outside of the reinforcing core, an isolation plate and a protective layer are provided on the outside of the base sleeve, and a fixing layer is also provided on the outside of the protective layer.

[0006] The isolation plates are configured in five groups, which are respectively placed in the gaps between the optical fiber core, the power supply core, and the filler rope. The position of the isolation plates is fixed by a protective layer. The isolation plates separate the optical fiber core and the power supply core. When the power supply core is damaged during use, the isolation plates prevent leakage from the damaged power supply core from causing damage to the internal optical fiber core.

[0007] Preferably, the base sleeve includes a sleeve body and a slot. The sleeve body wraps around the outside of the reinforcing core wire, and the reinforcing core wire is fixed at the center of the cable through the sleeve body. The reinforcing core wire bears the external force on the cable, thereby improving the stability of the cable.

[0008] Preferably, five slots are provided, and the five slots are evenly distributed on the outside of the sleeve body. The bottom of the isolation plate is fixed by the slots to prevent the isolation plate from shifting.

[0009] Preferably, the isolation insert includes an insert body, a disconnect line, and an end plate, and the insert body is inserted into the slot to separate the optical fiber core, power core, and filler cord.

[0010] Preferably, the disconnect line is formed on the surface of the plug body, and the end plate is disposed on the outer edge of the plug body. The disconnect line can be torn open when subjected to external force. The end plate applies a pulling force to the plug body, causing the plug body to break along the disconnect line, thereby removing the plug body and separating the optical fiber core, power core and filler rope in the cable.

[0011] Preferably, the protective layer includes a filling layer, a limiting slot, and a positioning layer. The limiting slot is formed on the filling layer and the positioning layer, and the limiting slot wraps around the outside of the insert plate body. The insert plate body is fixed by the limiting slot, and the protective layer can be separated when the insert plate body is disconnected.

[0012] Preferably, the fixing layer includes a fixing sleeve and a positioning groove. The fixing sleeve is wrapped around the outside of the positioning layer, and the positioning groove is wrapped around the outside of the end plate, thereby fixing the end plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model includes an optical fiber core, a power core, a filler rope, and a reinforcing core. A base sleeve is provided on the outside of the reinforcing core, and an isolation plate and a protective layer are provided on the outside of the base sleeve. A fixing layer is also provided on the outside of the protective layer. The base sleeve includes a sleeve body and a slot. The sleeve body wraps around the outside of the reinforcing core, fixing the reinforcing core at the center of the cable. The reinforcing core bears the external force on the cable, improving the stability of the cable. Five sets of isolation plates are provided, which are respectively located in the gaps between the optical fiber core, the power core, and the filler rope. The protective layer fixes the position of the isolation plates. The isolation plates separate the optical fiber core and the power core. When the power core is damaged during use, the isolation plates prevent leakage from the damaged power core from damaging the internal optical fiber core.

[0015] 2. In this utility model, the isolation plug includes a plug body, a disconnect line, and an end plate. The plug body is inserted into a slot and separates the optical fiber core, power core, and filler rope through the plug body. The disconnect line is opened on the surface of the plug body, and the end plate is set on the outer edge of the plug body. When the disconnect line is subjected to external force, it can be torn open. The end plate applies a pulling force to the plug body, causing the plug body to break along the disconnect line, so that the plug body can be removed. This separates the optical fiber core, power core, and filler rope in the cable. Thus, when the power cable is damaged, the power cable can be separated from the optical fiber core in time, which facilitates the repair of the power cable. Attached Figure Description
