[0031] The following will Figure 1-8 further elaborate on this application in conjunction with the attached drawings.

[0032] The embodiment of this application discloses an optical and electrical composite drag chain cable.

[0033] Referring to Figure 1-8 , an optical and electrical composite drag chain cable includes a drag chain cable body 1. The drag chain cable body 1 includes a plurality of cable core assemblies 11, an anti-tensile assembly 12, a ring-shaped skeleton 13, and an outer sheath 15. The ring-shaped skeleton 13 is installed equidistantly inside the outer sheath 15, and a plurality of cable core assemblies 11 are vertically arranged equidistantly in a ring shape inside the outer sheath 15. The cable core assemblies 11 can penetrate the ring-shaped skeleton 13. The anti-tensile assembly 12 is located between a plurality of cable core assemblies 11, and the anti-tensile assembly 12 can penetrate the ring-shaped skeleton 13. The cable core assembly 11 includes a cable core 111, an insulation layer 112, a shielding layer 113, and an inner sheath 114. An insulation layer 112 is sleeved outside the cable core 111, a shielding layer 113 is sleeved outside the insulation layer 112, and an inner sheath 114 is sleeved outside the shielding layer 113. A positioning mechanism is provided between the cable core assembly 11 and the ring-shaped skeleton 13. The anti-tensile assembly 12 includes an aramid fiber rope 121, a reinforcement layer 122, and an elastic layer 123. A reinforcement layer 122 is sleeved outside the aramid fiber rope 121, and an elastic layer 123 is sleeved outside the reinforcement layer 122. A fixing mechanism is provided between the anti-tensile assembly 12 and the ring-shaped skeleton 13. A filling layer 14 is filled between the outer sheath 15 and the cable core assembly 11.

[0034] In this embodiment, a plurality of first mounting holes 132 are formed in the ring-shaped skeleton 13, and the cable core assembly 11 penetrates the ring-shaped skeleton 13 through the first mounting holes 132. A second mounting hole 133 is formed at the central position of the ring-shaped skeleton 13, and the anti-tensile assembly 12 penetrates the second mounting hole 133. Such a structural design enables the cable core assembly 11 and the anti-tensile assembly 12 to be accurately positioned on the ring-shaped skeleton 13, significantly improving the regularity of the internal component layout of the cable and laying a solid foundation for the stable transmission of electricity and signals by the cable.

[0035] In this embodiment, a plurality of rubber rods 131 are fixedly installed between two connected annular skeletons 13, and the plurality of rubber rods 131 are arranged in an annular shape with equal spacing. This can not only effectively buffer the force between adjacent annular skeletons 13 when the cable is bent, but also avoid damage to the internal structure of the cable due to local stress concentration, greatly enhancing the reliability of the cable under frequent bending conditions.

[0036] In this embodiment, the positioning mechanism includes a positioning plate 202 and a rubber fixing sleeve 205. The outer fixing sleeve of the inner sheath 114 is provided with a positioning plate 202 and a rubber fixing sleeve 205, and the rubber fixing sleeve 205 is located at the front side of the corresponding positioning plate 202. The rubber fixing sleeve 205 can pass through the corresponding annular frame 13 through the mounting hole 132, and the positioning plate 202 is in contact with the back side of the corresponding annular frame 13. This design can ensure that the position of the cable core assembly 11 inside the cable is stable, greatly reducing the risk of displacement of the cable core assembly 11 due to external force, and effectively ensuring the stability of signal transmission.

[0037] In this embodiment, the annular frame 13 is provided with a plurality of jacks 201, and the plurality of jacks 201 are arranged at equal intervals with the corresponding mounting hole 132 as the center of the circle, and the front side of the positioning plate 202 is provided with a plurality of plug rods 203 at equal intervals in an annular shape, and the plug rods 203 can pass through the corresponding jacks 201 and are fixedly installed with conical rubber heads 204. The fixing effect of the positioning mechanism is further strengthened, so that the connection between the cable core assembly 11 and the annular frame 13 is more tightly connected, and the loosening phenomenon of the cable core assembly 11 in long-term use is effectively prevented.

[0038] In this embodiment, a positioning hole 301 is provided on the inner wall of the mounting hole, a positioning seat 302 is installed on the outer side of the elastic layer 123, and the positioning seat 302 can penetrate the corresponding positioning hole 301, and the fixing mechanism includes a second rubber fixing sleeve 303 and an annular baffle 304, and the outer fixing sleeve of the elastic layer 123 is provided with a second rubber fixing sleeve 303 and an annular baffle 304, and the annular frame 13 is located between the second rubber fixing sleeve 303 and the annular baffle 304. This fixing mechanism fully limits the displacement of the anti-stretching component 12, so that the anti-stretching component 12 can play a stable role when subjected to tension, greatly improving the anti-stretching performance of the cable.

[0039] In this embodiment, the outer sheath 15 includes a fixed layer 151, an outer sheath 152 and a wear-resistant layer 153. The outer sheath 152 is arranged on the outside of the fixed sheath, and the wear-resistant layer 153 is arranged on the outside of the outer sheath 152. This layered design significantly improves the overall protection capability of the cable, can effectively resist external physical damage, chemical corrosion, etc., and greatly prolongs the service life of the cable.

[0040] In this embodiment, an annular groove 401 is formed on the inner wall of the fixed layer 151, and an annular seat 402 is fixedly installed on the outer side of the annular skeleton 13, and the annular seat 402 is installed in the corresponding annular groove 401. This structure enhances the connection stability between the annular skeleton 13 and the fixed layer 151 of the outer sheath 15, ensures the stable position of the annular skeleton 13 within the outer sheath 15, and further guarantees the stability of the entire cable structure.

[0041] In this embodiment, the outer sheath 152 is made of polyurethane material, which has good abrasion resistance, oil resistance, chemical corrosion resistance and flexibility, can adapt to various harsh working environments, and protects the wire core inside the cable from being eroded by the external environment. Relying on the excellent properties of the polyurethane material, the cable can be widely used in various complex and harsh scenarios, greatly broadening the application range of the cable.

[0042] In the present invention, by setting a plurality of cable core components 11 and anti-stretch components 12, and using an annular skeleton 13 to support and position them, the overall structural stability of the cable can be significantly improved. The plurality of cable core components 11 are distributed in an annular shape with equal spacing, forming a stable internal layout, which can cooperate with each other when transmitting power and signals to reduce interference. The aramid fiber rope 121 in the anti-stretch component 12 has the characteristics of high strength and low density. As the main anti-stretch element, it can withstand a large tensile force. The reinforcement layer 122 further enhances the structural strength of the anti-stretch component 12 to prevent the aramid fiber rope 121 from breaking or dispersing during the force. The spring layer gives the anti-stretch component 12 good elasticity. When the cable is subjected to a tensile force, the spring layer can absorb part of the tensile energy through its own elastic deformation, and work in conjunction with the aramid fiber rope 121 to effectively enhance the tensile resistance of the cable. The positioning mechanism between the cable core component 11 and the annular skeleton 13, and the fixing mechanism between the anti-stretch component 12 and the annular skeleton 13 play a key role in ensuring the stability of the cable performance. The positioning plate 202 and the rubber fixing sleeve 1 205 in the positioning mechanism cooperate with each other. The rubber fixing sleeve 1 205 passes through the mounting hole 132 on the annular frame 13 to preliminarily position the cable core assembly 11. The positioning plate 202 is in close contact with the rear side of the annular frame 13 to prevent the cable core assembly 11 from axially moving inside the cable. In addition, the conical rubber head 204 on the positioning plate 202 is inserted into the jacks 201 arranged at equal intervals with the mounting hole 132 as the center of the circle on the annular frame 13, further enhancing the firmness of the positioning, so that the cable core assembly 11 always remains in the predetermined position during long-term use, avoiding unstable signal transmission or power transmission failure caused by the displacement of the cable core assembly 11. The fixing mechanism between the anti-stretching component 12 and the annular skeleton 13 tightly clamps the annular skeleton 13 in the middle through the rubber fixing sleeve 2 303 and the annular baffle 304. The positioning seat 302 on the outside of the elastic layer 123 cooperates with the positioning hole 301 on the inner wall of the mounting hole of the annular skeleton 13, which limits the radial and axial movement of the anti-stretching component 12, ensuring that the anti-stretching component 12 can play a stable role when subjected to tension, thereby ensuring the stability of the overall performance of the cable;

[0043] The outer sheath 15 adopts the structural design of a fixing layer 151, an outer protective sheath 152 and a wear-resistant layer 153, and the outer protective sheath 152 is made of polyurethane material, which greatly improves the protection performance of the cable. The fixing layer 151 mainly plays a role in supporting and fixing the inner layer structure. The annular groove 401 on its inner wall is closely matched with the annular seat 402 on the outer side of the annular skeleton 13, making the installation of the annular skeleton 13 in the outer sheath 15 more stable and enhancing the integrity of the entire cable structure. The polyurethane material used for the outer protective sheath 152 has good wear resistance. In an environment where the cable frequently rubs against external objects, a plurality of rubber rods 131 are fixedly installed between two adjacent annular skeletons 13, and the plurality of rubber rods 131 are arranged at equal intervals in a ring shape. This design plays an important buffering role when the cable is bent. When the cable is bent, relative displacement will occur between adjacent annular skeletons 13, and the rubber rods 131 can absorb and disperse the bending stress during this process, avoiding damage to the cable core assembly 11 and the anti-tensile assembly 12 inside the cable due to local stress concentration.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
