Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high-strength tensile-resistant cable. Background Art

[0002] The cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, and are used to connect circuits, electrical appliances, etc.

[0003] Prior art, such as a utility model patent document with authorization announcement number "CN221200786U" and patent name "A bending-resistant cable", discloses a cable comprising a cable body, an outer sheath being provided on the outer side of the cable body, and an installation cavity being formed between the cable body and the outer sheath, a protective component being provided inside the installation cavity, and the protective component being wrapped around the outside of the cable body, the protective component comprising a plurality of first protective elastic rods and a plurality of second protective elastic rods, and the plurality of the first protective elastic rods and the plurality of the second protective elastic rods being staggered and fixedly connected to each other.

[0004] In actual use, the cable often wears out, which requires the protective cover on the outer layer of the cable core to be peeled off, and then the cable core is reconnected. However, due to the provision of a protective component in the above patent, it is not only laborious to peel off the outer protective cover, but also the interface is relatively fragile and the hardness of the connection is low, resulting in poor tensile strength of the cable. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a high-strength tensile-resistant cable, which is used to solve the technical problem that some high-strength tensile-resistant cables mentioned in the background technology are more laborious in the process of stripping off the outer protective cover, and the interface at this time is relatively fragile, and the hardness of the connection is relatively low, resulting in poor tensile resistance of the cable.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A high-strength tensile cable comprises a protective outer jacket, an inner jacket arranged inside the protective outer jacket and a cable core arranged inside the inner jacket, a first reinforcement member is arranged between the inner jacket and the protective outer jacket, the first reinforcement member is intermittently distributed on the same cable, the cable segment provided with the first reinforcement member is a reinforcement segment, a second reinforcement member is arranged between two adjacent reinforcement segments, and the second reinforcement member is arranged outside the protective outer jacket.

[0008] Working principle:

[0009] When it is found that the cable is worn, the operator strips off the protective jacket of the portion where the first cylinder is not provided, and then reconnects the two sections of the cable; this time by installing the second reinforcement member on the outside of the two sections of the cable.

[0010] Beneficial effects:

[0011] By setting the first reinforcement member, the strength of each section of the cable is increased, and the state of the cable body here does not change, that is, the tensile effect of the cable is increased; and by discontinuous distribution, it is prevented from being difficult to separate the cable at the faulty part due to the setting of the first reinforcement member, so that it is convenient for the operator to strip off the protective jacket without the first reinforcement member, which is more labor-saving and reduces the maintenance cost;

[0012] By providing a second reinforcement member, the two reinforcement sections can be connected and the hardness of the connection can be enhanced, thereby avoiding a reduction in the overall tensile strength of the cable due to reconnection of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Example:

[0019] like Figure 1 and Figure 2As shown, a high-strength tensile cable comprises a protective jacket 1, an inner jacket 2 arranged inside the protective jacket 1 and a cable core 3 arranged inside the inner jacket 2, wherein the protective jacket 1 is a cross-linked polyethylene insulated thermoplastic jacket, the inner jacket 2 is made of polyvinyl chloride, the cable core 3 is a copper conductor, a first reinforcement member is arranged between the inner jacket 2 and the protective jacket 1, the first reinforcement member is intermittently distributed on the same cable, the cable segment provided with the first reinforcement member is a reinforcement segment, a second reinforcement member is arranged between two adjacent reinforcement segments, and the second reinforcement member is arranged outside the protective jacket 1.

[0020] By setting the first reinforcement, the strength of each section of the cable is increased, and the state of the cable here does not change, that is, the tensile effect of the cable is increased; and by discontinuous distribution, it is prevented from being difficult to separate the faulty part of the cable due to the setting of the first reinforcement, so that it is convenient for the operator to strip off the protective jacket 1 where the first reinforcement is not set, which is more labor-saving and reduces maintenance costs; by setting the second reinforcement, the two reinforcement sections can be connected and the hardness of the connection can be strengthened, avoiding the reduction of the overall tensile effect of the cable due to the reconnection of the cable.

[0021] like Figure 1 and Figure 2 As shown, the first reinforcement is a first cylinder 5 , the material of the first cylinder 5 is carbon fiber, and the first cylinder 5 is connected to the inner sheath 2 and the protective outer sheath 1 .

[0022] like Figure 3 As shown, the second reinforcement is a cylindrical frame 6, which includes three elastic connecting rods 7 and several second cylinders 10 parallel to the length direction of the cable. The material of the second cylinder 10 is also carbon fiber. The three connecting rods 7 are parallel to each other and are sequentially arranged around the outer periphery of the protective jacket 1 of the cable. The elastic properties of the connecting rods 7 can help the cylindrical frame 6 as a whole to reduce the damage caused to the cylindrical frame 6 itself after a long period of bending, and the two sides of the cylindrical frame 6 can be flexibly approached or moved away to adapt to wrapping cables of different diameters. The second cylinder 10 is fixed between two adjacent connecting rods 7; the two connecting rods 7 arranged at both ends of the cylindrical frame 6 are provided with a locking threaded tube 8 with an external thread, and the locking threaded tube 8 is made of insulating material. A circular hole is opened on the first cylinder 5, and a penetration hole is provided in the protective jacket 1. The circular hole and the penetration hole are connected and a threaded sleeve 9 with an internal thread is fixed, and the threaded sleeve 9 is made of insulating material. The locking threaded tube 8 is threadedly penetrated in the threaded sleeve 9. By arranging the cylindrical frame 6, the locking threaded tube 8 and the threaded sleeve 9, the cylindrical frame 6 is sleeved on the outer wall of the cable, and then the locking threaded tube 8 is screwed into the threaded sleeve 9 to lock the cylindrical frame 6.

[0023] like Figure 2 and Figure 3As shown, one end of the connecting rod 7 is also provided with a through hole, which is communicated with the round hole and the through hole on the protective jacket 1; the other end of the connecting rod 7 is provided with a sleeve 12, and the sleeve 12 is made of plastic material. The length of the sleeve 12 is greater than the diameter of the threaded sleeve 9. The setting of the sleeve 12 facilitates the flexible adjustment of both sides of the cylindrical frame 6, and the locking threaded tube 8 passes through the sleeve 12 and is threadedly connected with the threaded sleeve 9 to adapt to the wrapping of cables of different diameters.

[0024] like Figure 1 and Figure 2 As shown, a filler 11 is disposed on the outer side of the inner sheath 2. The filler 11 is made of low-smoke halogen-free flame-retardant polyethylene material, which can make the cable flame-retardant. The filler 11 can effectively avoid mechanical stress and compression deformation during use. Figure 1 and Figure 2 As shown, an insulating layer 4 is provided on the outside of the filler 11. The insulating layer 4 is made of polypropylene, which can make the cable core 3 have better heat resistance and stability, and the insulating layer 4 can prevent the current from passing through the cable sheath into the cable core 3, thereby preventing electrical accidents such as electric shock and short circuit, and effectively improving the safety and durability of the cable; an installation cavity is provided between the insulating layer 4 and the protective jacket 1, and the first cylinder 5 is arranged inside the installation cavity and the side walls are glued to the insulating layer 4 and the protective jacket 1 respectively.

[0025] Working principle:

[0026] When the cable is found to be worn, the operator removes the protective jacket 1 of the part where the first cylinder 5 is not provided, cuts off the cable of the faulty part, and then reconnects the two new cable cores 3;

[0027] At this time, wrap the cylindrical frame 6 around the connection of the cable, and connect the connecting rods 7 on both sides of the cylindrical frame 6 to the two sections of the cable respectively, then pull one side of the connecting rod 7 to make the cylindrical frame 6 fit tightly to the surface of the cable and wrap the cable firmly, then screw the locking threaded tube 8 into the threaded sleeve 9 to firmly lock the cylindrical frame 6 and the cable, and the whole operation is completed.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
