Description

Technical Field

[0001] The utility model relates to a cable, in particular to a two-in-one cable of a power cable and a network cable. Background Art

[0002] In automation equipment and assembly lines, the modules that execute the corresponding processes are generally active. On the one hand, the modules that execute the corresponding processes need to be connected to the power supply through the power cord to supply power to them. On the other hand, the modules that execute the corresponding processes also need to be connected to the control end through the network cable to control some parameters in the process of executing the corresponding processes. For example, in automatic screw driving equipment, the electric screwdriver that tightens the screws needs to be powered by a power supply, and the control end also needs to control the torque in the process of tightening the screws. The power cord and network cable mentioned above are generally used with a matching drag chain. During the activity of the modules that execute the corresponding processes, the drag chain is deformed, and the power cord and network cable are also deformed. Figure 3 The existing power cables and network cables are separately arranged, and there are still problems such as: it is inconvenient to arrange them in the drag chain; in the process of continuous bending, deformation and recovery, the corresponding positions are prone to damage and breakage.

[0027] See also Figure 1 and Figure 2 A two-in-one power cable and network cable includes a network cable part 1, a power cable part 2, a wrapping layer 3, a filling layer 4 and a second wrapping layer 5.

[0028] The network cable part 1 includes ten first cores 1a and a first coating layer 1b covering the ten first cores 1a. The power cable part 2 includes two second cores 2a. The network cable part 1 and the power cable part 2 are both in the tape layer 3. The filling layer 4 is arranged in the tape layer 3 to fill the gap between the tape layer 3 and the network cable part 1 and between the tape layer 3 and the power cable part 2. The second coating layer 5 is coated on the tape layer 3. Specifically, the processing process of the power cable and network cable two-in-one cable can be: the network cable part 1 and the power cable part 2 pass through an extruder, and the filling layer 4 is coated on both; the network cable part 1 and the power cable part 2 coated with the filling layer 4 pass through a wrapping machine, and the tape is wrapped outside the filling layer 4 to form the tape layer 3; the network cable part 1 and the power cable part 2 wrapped with the tape pass through an extruder, and the second coating layer 5 is coated on the tape layer 3.

[0029] Optionally, the cross section of the second coating layer 5 is circular, and accordingly, the outer edges of the tape layer 3 and the filling layer 4 are circular. That is, the outer edge of the two-in-one power cable and network cable is circular, and compared with designing the outer edge of the two-in-one power cable and network cable to be elliptical or flat, the circular shape has a stronger ability to recover after bending deformation.

[0030] Based on the above-mentioned design of "the cross section of the second coating layer 5 is in a circular ring shape", optionally, the cross section of the mesh cable part 1 is flat (the flat shape here means: setting a perpendicular long axis and short axis; the ten first cores 1a are divided into several rows, and several rows of first cores 1a are arranged along the long axis or the short axis; each row of first cores 1a are in contact with each other, and the two adjacent rows of first cores 1a are also in contact with each other; the ten arranged first cores 1a are symmetrical about the long axis and the short axis, and the length occupied by the ten arranged first cores 1a on the long axis is greater than the length occupied on the short axis). The long axis is set as the first direction 1c, and the short axis is set as the second direction 1d. The two second wires are arranged side by side along the first direction 1c and are located on one side of the mesh cable part 1 in the second direction 1d.

[0031] In this way, the cross-section of the network cable part 1 is designed to be flat, leaving space in the second direction 1d to facilitate the subsequent arrangement of the power cable part 2, so that the network cable part 1 and the power cable part 2 can be arranged relatively evenly in the wrapping layer 3 with a circular outer edge.

[0032] See also Figure 1 Furthermore, the cross-section of the network cable portion 1 is flat and can be designed as follows: the ten first wire cores 1a are divided into three rows, the three rows are arranged along the second direction 1d, and the number of wires in the three rows is three, four, and three respectively.

[0033] See also Figure 2 Furthermore, the flat cross-section of the network cable portion 1 can also be designed as follows: the ten first wire cores 1a are divided into five rows, the five rows are arranged along the first direction 1c, and the numbers of the five rows are one, two, three, two and one respectively.

[0034] Optionally, the filling layer 4 is made of polypropylene. During the bending and deformation of the power cable and network cable two-in-one cable, the filling layer 4 serves as a buffer part for protecting the network cable part 1 and the power cable part 2 and connecting the wrapping layer 3. Polypropylene is used, which has stable chemical properties, good insulation, heat resistance and the ability to recover after bending and deformation.
