According to the utility model, the signal line and the power line are optimized and integrated into an integrated structure, thereby not only reducing the process of branching and bushing penetration in subsequent line installation processing and meeting the requirement of automatic operation, but also having a POE function and having a very wide market prospect.

Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular provides a dual-parallel cable supporting a POE function. Background Art

[0002] Most of the cables currently on the market that support POE functions are circular in structure. During the subsequent wiring harness processing, the signal lines and power lines of these cables need to be routed separately, and then protected with PVC sheaths. This operation is cumbersome and time-consuming. In addition, the structural characteristics of circular cables also limit the compatibility of automated production, affecting production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a dual-parallel cable that supports POE function. The cable satisfies the needs of convenient wire assembly processing, can be adapted to automated operations, and has POE function, thus having a very broad market prospect.

[0004] The utility model adopts the following technical solutions:

[0005] A dual-parallel cable supporting POE function is characterized in that: the cable includes a signal line, a power line and an outer sheath, the outer sheath includes a signal line outer sheath and a power line outer sheath, and is an integrated sheath layer formed by arranging the signal line and the power line in parallel and uniformly extruding polyvinyl chloride on the outside; the signal line and the power line are respectively arranged inside the signal line outer sheath and the power line outer sheath, and the cores of the signal line and the power line are both tinned oxygen-free copper soft conductors.

[0006] In this example, preferably, there are four signal lines, which are twisted into cables in pairs, and two power lines are arranged side by side.

[0007] In this example, preferably, an aluminum-plastic composite tape is provided on the inner side of the outer sheath of the signal line, and a transparent Mylar tape is provided on the inner side of the aluminum-plastic composite tape.

[0008] In this example, preferably, a filling rope is further provided inside the outer sheath of the signal line, and the filling rope and the signal line are jointly covered inside the transparent Mylar tape.

[0009] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0010] The double-parallel structure cable provided by the utility model sets the signal line and the power line into an integrated structure. On the one hand, it reduces the subsequent wire assembly processing and wire separation and casing threading process, saving labor time; on the other hand, the reasonable structural design makes the cable adaptable to automated operations, reduces manual intervention, and improves the production efficiency of the wire harness processing end; at the same time, the integrated outer sheath design saves material consumption of the outer sheath and reduces production costs.
