[0011] The outer sheath is located outside the filler layer;

[0012] Also includes:

[0013] The tensile reinforcement mechanism, located on the outer sheath, is used to enhance the tensile strength and power of the cable.

[0026] Beneficial effects

[0027] Compared with the prior art, the present invention provides a cable with high tensile strength, which has the following beneficial effects:

[0028] 1. In this invention, the number of braided meshes is consistent with that of the shielding protection layer. The braided meshes improve the protective effect of the shielding protection layer and enhance the overall strength of the cable. The reinforcing layer is fitted over the filling layer to further enhance the strength of the filling layer. The supporting layer is fixed between the reinforcing layer and the outer sheath to provide stable support for the reinforcing layer.

[0029] 2. In this invention, the conical blocks are divided into multiple groups, with each group of conical blocks forming a ring. The conical blocks and conical slots cooperate with each other to improve the connection strength between the reinforcing layer and the filling layer, while also improving their tensile strength.

[0031] 4. In this invention, the reinforcing rod is embedded between the corresponding multiple conical slots, and the conical block is fixed to the outside of the reinforcing rod. The reinforcing rod can improve the connection stability between the conical slot and the conical block, and prevent gaps from appearing between the conical slot and the corresponding conical block when subjected to tensile force, thereby improving the performance of the tensile component.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example:

[0044] Please see Figure 1-7 The present invention provides the following technical solutions:

[0045] A high tensile strength cable is composed of a cable core 1, an insulation layer 2, a shielding protection layer 3, a filling layer 4, an outer sheath 5, and a tensile strengthening mechanism. Specifically, the insulation layer 2 is disposed outside the cable core 1, the shielding protection layer 3 is disposed outside the insulation layer 2, the filling layer 4 is disposed outside the shielding protection layer 3, and the outer sheath 5 is disposed outside the filling layer 4. Multiple cable cores 1, insulation layers 2, and shielding protection layers 3 are provided, and the number of cable cores 1, insulation layers 2, and shielding protection layers 3 is the same.

[0046] In this embodiment, the number of cable core 1, insulation layer 2 and shielding protection layer 3 can be adjusted according to the actual situation. The filling layer 4 is wrapped around the outside of multiple shielding protection layers 3. The insulation layer 2 is made of any material of PVC, XLPE or rubber. The shielding protection layer 3 is made of aluminum foil. The filling layer 4 is made of PP material mixed with various fibers, which improves its tensile strength to a certain extent. The outer sheath 5 is made of any material of PVC, PE or rubber, and provides protection for the cable through the outer sheath 5.

[0047] Please see Figure 2-7 The outer sheath 5 is provided with a tensile reinforcement mechanism to improve the tensile strength and power of the cable. The tensile reinforcement mechanism consists of a reinforcing component 6 and a tensile component 7, as described in detail below:

[0048] The reinforcing component 6 is disposed inside the outer sheath 5 to improve the cable strength. Specifically, the reinforcing component 6 includes a braided mesh 601, a reinforcing layer 602 and a supporting layer 603. The braided mesh 601 is fixedly sleeved on the outer wall of the shielding protection layer 3, the reinforcing layer 602 is fixedly sleeved on the outer wall of the filling layer 4, and the supporting layer 603 is fixedly sleeved on the outer wall of the reinforcing layer 602.

[0049] Tensile component 7 is disposed on reinforcing component 6 to improve the tensile strength of the cable. Specifically, tensile component 7 includes conical locking block 701 and connecting rod 702. Multiple conical locking blocks 701 are provided, and each conical locking block 701 is fixedly connected to the outer wall of filling layer 4. Multiple conical locking grooves are correspondingly opened on the inner wall of reinforcing layer 602. Multiple sets of connecting rods 702 are provided, and multiple connecting rods 702 are provided in each set. Multiple connecting rods 702 in each set are fixedly connected to the inner wall of support layer 603, and the other end of multiple connecting rods 702 in each set is fixedly connected to the outer wall of the corresponding shielding protection layer 3.

[0050] In this embodiment, the number of braided mesh 601 is consistent with that of the shielding protection layer 3. The braided mesh 601 improves the protective effect of the shielding protection layer 3 and enhances the overall strength of the cable. The reinforcing layer 602 is fitted over the filling layer 4, further enhancing the strength of the filling layer 4. The support layer 603 is fixed between the reinforcing layer 602 and the outer sheath 5, providing stable support for the reinforcing layer 602. The conical locking blocks 701 are divided into multiple groups, each group forming a ring. The conical locking blocks 701 and the conical slots cooperate with each other to improve the connection strength between the reinforcing layer 602 and the filling layer 4, while also improving its tensile strength. The connecting rod 702 is fixedly connected to the support layer 603 and the shielding protection layer 3, providing support for the shielding protection layer 3 and its internal cable core 1, ensuring the stability of the cable core 1. At the same time, each connecting rod 702 penetrates the reinforcing layer 602, further enhancing the strength and stability of the reinforcing layer 602.

[0051] Please see Figure 3 The tensile component 7 also includes a tensile rib 703, which is fixedly embedded inside the filling layer 4.

[0052] In this embodiment, the tensile reinforcement 703 is located at the center of the filling layer 4 and between multiple cable cores 1. The tensile reinforcement 703 is made of aramid fiber material, which enables the multiple cable cores 1 to withstand greater tearing force and further improve the tensile strength of the cable.

[0053] Please see Figure 4-5 Multiple reinforcing rods 704 are fixedly embedded between the inner walls of multiple conical slots, and each reinforcing rod 704 penetrates the corresponding conical block 701.

[0054] In this embodiment, the reinforcing rod 704 is embedded between the corresponding multiple conical slots, and the conical block 701 is fixed to the outside of the reinforcing rod 704. The reinforcing rod 704 can improve the connection stability between the conical slot and the conical block 701, and prevent gaps from appearing between the conical slot and the corresponding conical block 701 when subjected to tensile force, thereby improving the performance of the tensile component 7.

[0055] Please see Figure 3 Both the reinforcing layer 602 and the supporting layer 603 are hexagonal tubular in shape;

[0056] Both the reinforcing layer 602 and the supporting layer 603 are made of PUR material.

[0057] In this embodiment, both the reinforcing layer 602 and the supporting layer 603 are hexagonal tubes. The hexagonal shape has good stability and improves the performance of the reinforcing component 6. The PUR material has excellent high strength and durability, which further improves the strength of the reinforcing component 6.

[0058] Please see Figure 6 Multiple mesh grooves are correspondingly formed on the inner wall of the filling layer 4.

[0059] In this embodiment, a mesh groove is provided on the inner wall of the filling layer 4, and the mesh groove and the woven mesh 601 have the same shape. By cooperating with the mesh groove and the corresponding woven mesh 601, the tensile strength of the shielding protection layer 3 and the filling layer 4 is further improved.

[0060] Please see Figure 3 The outer wall of the support layer 603 is fixedly connected with multiple arc-shaped embedded blocks 8, and the inner wall of the outer sheath 5 is provided with multiple arc-shaped embedded grooves.

[0061] In this embodiment, the connection strength between the support layer 603 and the outer sheath 5 is improved by the cooperation of the arc-shaped embedding block 8 and the arc-shaped embedding groove.

[0062] Working principle: Insulation layer 2 is disposed outside cable core 1, shielding layer 3 is disposed outside insulation layer 2, filling layer 4 is disposed outside shielding layer 3, outer sheath 5 is disposed outside filling layer 4, and tensile reinforcement mechanism is disposed on outer sheath 5. A braided mesh 601, a reinforcing layer 602, and a support layer 603 are disposed outside shielding layer 3. The braided mesh 601 improves the protective effect of shielding layer 3 and also increases the overall strength of the cable. The reinforcing layer 602 is fitted outside filling layer 4, further enhancing the tensile strength of filling layer 4. For strength, the support layer 603 is fixed between the reinforcing layer 602 and the outer sheath 5. The support layer 603 provides stable support for the reinforcing layer 602. The conical block 701 and the conical slot cooperate to improve the connection strength and tensile strength of the reinforcing layer 602 and the filling layer 4. The connecting rod 702 fixes the support layer 603 and the shielding protection layer 3, providing support for the shielding protection layer 3 and its internal cable core 1, ensuring the stability of the cable core 1. At the same time, each connecting rod 702 penetrates the reinforcing layer 602, further improving the strength and stability of the reinforcing layer 602.
