Drawings
Fig. 1 is a schematic structural diagram of a composite cable with both signal and power according to an embodiment of the present invention.
Detailed Description
Fig. 1 schematically shows a composite cable of one embodiment of the present invention with both signal and power. As shown in fig. 1, the composite cable with both signal and power comprises a signal wire 1, a power wire 2, a filler strip 3 and a protective sleeve 4.
Three power lines 2 are provided. The three power lines 2 are arranged in a tangent way in pairs. The power wire 2 includes a power wire conductor 21 and a power wire insulating layer 22 covering the outside of the power wire conductor 21. In this embodiment, the power line conductor 21 is formed by stranding and compressing 136 bare copper wires having a cross-sectional area of 0.15 mm square. The power wire conductor 21 has an overall cross-section of 2.5 square millimeters. The power line insulating layer 22 is made of elastic polyethylene.
Two signal lines 1 are provided. Two signal wires 1 are distributed on two sides of one power wire 2. The signal wires 1 are respectively tangent to the two power wires 2. Therefore, the size of the overall outer diameter of the cable can be reduced, and materials are saved. Meanwhile, the two signal wires 1 are separated to be independently shielded, so that the shielding effect is better, and the mutual interference of the two signal wires 1 is avoided. The signal line 1 includes a signal line conductor 11, a signal line insulating layer 12 covering the outside of the signal line conductor 11, and a taping 13 covering the outside of the signal line insulating layer 12. The signal line conductor 11 is formed by twisting and pressing a bare copper wire and a copper foil wire. In this embodiment, the signal line conductor is formed by twisting and compressing 28 bare copper wires having a cross-sectional area of 0.15 mm square and one copper foil wire. Therefore, the flexibility of the signal wire can be maintained, meanwhile, the strength of the signal wire can be guaranteed, and the copper foil wire can be used as a pulling force center to increase the strength of the signal wire under the condition of back-and-forth pulling, so that the signal wire is not easy to break in the using process. The material of the signal line insulating layer 12 is elastic polyethylene. The outside of the insulating layer 12 is covered with a wrapping tape 13 for shielding. The wrapping tape 13 is made of aluminum foil. After the two signal wires 1 are respectively arranged, the requirement on shielding is reduced, and the signal wires can be better shielded by the wrapping tape 13.
And filling strips 3 are filled in gaps between the protective sleeve 4 and the power lines 1 and between the protective sleeve and the signal lines 2. The filling strips 3 are non-woven fabrics. The protective sleeve 4 is made of thermoplastic elastomer.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept herein, and it is intended to cover all such modifications and variations as fall within the scope of the utility model.
