a composite cable

Abstract

The invention relates to a composite cable, comprising: a plurality of baffles are uniformly and fixedly connected to the outer peripheral side of a first reinforcing core, conductive wire cores are arranged in the cavities formed between every two adjacent baffles, and the first shielding Layers are sleeved on the outside of all baffles, the second shielding layer is sleeved on the outer peripheral side of the first shielding layer and forms an annular cavity with the first shielding layer, and multiple optical fiber cores are evenly arrayed around the axis of the annular cavity Distributed in the annular cavity, the gap between the first shielding layer, the second shielding layer and multiple optical fiber cores is filled with the first filling layer, and the outer sheath of the cable is sleeved on the outer peripheral side of the second shielding layer; through this The invention realizes the integration of conductive transmission and signal transmission functions, reduces the signal interference between various cables, and improves the tensile and bending strength of the composite cable. Positioning is simple.

Description

technical field [0001] The invention relates to the field of cables, in particular to a composite cable. Background technique [0002] At present, most cables are used for connecting wires for transmission and distribution of electric energy, and are widely used in the electrical field. Most cables are formed by wrapping and winding conductors with an outer insulating layer, and the conductors are provided with shielding layers or armor. A cable for optical signal transmission of communication signals. In the prior art, the optical cable and the cable are mostly set separately, and when the cable or the optical cable is broken due to external factors such as strong wind or snow accumulation, the location of the broken cable cannot be found in time and fixed. It was repaired in time, and at the same time, the inaccurate positioning of the multiple wire groups in the cable due to the circular cross section caused the winding of the multi-strand cable core to be difficult, and ...

[0002] At present, most cables are used for connecting wires for transmission and distribution of electric energy, and are widely used in the electrical field. Most cables are formed by wrapping and winding conductors with an outer insulating layer, and the conductors are provided with shielding layers or armor. A cable for optical signal transmission of communication signals. In the prior art, the optical cable and the cable are mostly set separately, and when the cable or the optical cable is broken due to external factors such as strong wind or snow accumulation, the location of the broken cable cannot be found in time and fixed. It has been repaired in time, and at the same time, the inaccurate positioning of the multiple wire groups in the cable due to the circular cross section makes it difficult to wind the multi-strand cable core, and there is a lack of a composite cable with high integration and good safety.
