Description

Technical Field

[0001] The utility model relates to the field of composite cables, in particular to a four-optical and three-electrical composite cable. Background Art

[0002] A four-fiber, three-electrical composite cable is a type of optoelectronic composite cable, typically consisting of two components, an optical fiber and an electrical cable, joined together through a specialized structural design. The optical fiber portion contains four optical fiber channels for high-speed data transmission, while the electrical cable portion contains three electrical channels for power supply. This structure enables the four-fiber, three-electrical composite cable to meet both communication and power supply needs.

[0003] Because the number of electrical cables is smaller than the number of optical cables, it's difficult to achieve equidistant spacing between optical cables within a composite cable, regardless of whether they're stranded or bundled together in a central tube. This discrepancy can cause different optical cables to experience varying signal interference, leading to differences in signal transmission rates across the four cables. Based on this, the present application provides a novel four-optical, three-electrical composite cable. Utility Model Content

[0004] To address the above problems, a four-optical and three-electrical composite cable is provided. By adding a filler cable with the same diameter as the conductive cable, the four optical cables arranged outside the four main cables are arranged at equal distances, ensuring that the signal transmission rates of the four optical cables are the same.

[0005] In order to solve the problems of the existing technology, the utility model provides a four-optical and three-electrical composite cable, including a core group composed of four main cables and four optical cables wrapped with tape, the four main cables have the same diameter, the four optical cables have the same diameter and the diameter of the optical cables is smaller than the diameter of the main cables, the core group has filling material, the four main cables include three conductive cables and one filling cable, the four optical cables are arranged on the periphery of the four main cables, and the core group is covered with an outer protective layer.

[0006] Preferably, the cross sections of the four main cables are arranged in a matrix, and one optical cable is arranged between two adjacent main cables.

[0007] Preferably, the conductive cable comprises a conductive core and an insulating layer.

[0008] Preferably, the wrapping tape is non-woven fabric.

[0009] Preferably, the filling material is aramid.

[0010] Preferably, the outer protective layer is made of thermoplastic elastic material.

[0011] Preferably, the filling cable is made of insulating material.

[0012] Preferably, a shielding layer is further provided between the conductive core and the insulating layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects: by adding a filling cable with the same diameter as the conductive cable, the four optical cables arranged outside the four main cables are arranged at equal distances, thereby ensuring that the signal transmission rates of the four optical cables are the same. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a cross-sectional view of the four-optical and three-electrical composite cable of the present invention.

[0015] The numbers in the figure are: 1, conductive cable; 11, conductive core; 12, insulation layer; 2, optical cable; 3, filling cable; 4, wrapping tape; 5, outer protective layer; 6, filling material. DETAILED DESCRIPTION

[0016] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] See also Figure 1 The four-optical, three-electrical composite cable shown includes a core group consisting of four main cables and four optical cables 2 wrapped with tape 4. The four main cables have the same diameter, and the four optical cables 2 have the same diameter, but the diameter of the optical cables 2 is smaller than that of the main cables. The core group contains filler material 6. The four main cables include three conductive cables 1 and one filler cable 3. The four optical cables 2 are arranged around the four main cables. The core group is covered with an outer protective layer 5. It should be noted that the filler cable 3 is made of insulating material.

[0018] The cross sections of the four main cables are arranged in a matrix, and one optical cable 2 is arranged between two adjacent main cables. Figure 1 As shown, after three conductive cables 1 and one filler cable 3 are closely arranged, four optical cables 2 are evenly distributed around the periphery of the four main cables. Regardless of whether they are combined in a layer-twisted or centrally bundled tube configuration, each optical cable 2 is identical to the other three optical cables 2. Therefore, the signal strength of each optical cable 2 is also the same, ensuring the same data transmission rate for each optical cable 2.

[0019] The conductive cable 1 includes a conductive core 11 and an insulating layer. A shielding layer is further provided between the conductive core 11 and the insulating layer 12.

[0020] The wrapping tape 4 is a non-woven fabric and is mainly used for bundling to ensure that the main cable and the optical cable 2 wrapped therein are tightly fitted.

[0021] The filling material 6 is aramid. Other common filling materials 6 can also be used. The main function of the filling material 6 is to strengthen the strength of the cable structure.

[0022] The outer protective layer 5 is made of thermoplastic elastic material and provides the composite cable with a certain degree of flexibility and protective strength.

[0023] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
