Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The embodiment of the present application solves the problem of reducing the service life of the cable by providing a high-strength pressure-resistant cable, prevents the cable body from breaking during long-term torsion, and thus can increase the service life of the cable body.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] The utility model embodiment discloses a high-strength compression-resistant cable.

[0033] According to the attached Figure 1-4 As shown, it includes a cable body 1, a plurality of cable cores 101 are arranged inside the cable body 1, and a compression-resistant unit 2 is arranged on the outer peripheral wall of the cable core 101. The compression-resistant unit 2 includes:

[0034] The support frame 201 is located between the multiple groups of cable cores 101; the support frame 201 is made of a deformable material, and can deform the torsional direction of the cable body 1 during use.

[0035] The reinforcing column 202 is located on the end face of the support frame 201, and supports the cable core 101 on all sides. During the use of the cable body 1, the arc grooves 203 provided at intervals on the outer wall of the support frame 201 can be used to twist the cable body 1 along the direction of the arc grooves 203, making it easy to twist and preventing the cable body 1 from breaking during long-term twisting. At the same time, the compressive resistance can be improved by the reinforcing column 202.

[0036] The support frame 201 is arranged in a cross shape, and arc grooves 203 are spaced apart on the outer peripheral wall of the support frame 201. The cable body 1 is twisted along the arc grooves 203. The reinforcing column 202 is made of metal material, which can support the inner wall around the insulating sleeve 208 and improve the overall strength of the cable body 1.

[0037] Multiple groups of reinforcing columns 202 are fixedly installed at intervals on the outer wall of the support frame 201, and insulating sleeves 208 are arranged on the periphery of multiple groups of cable cores 101. The insulating sleeves 208 have the function of insulating the multiple groups of cable cores 101. The top ends of the multiple groups of reinforcing columns 202 are fixedly connected to the inner wall of the insulating sleeve 208. It should be noted that multiple groups of first buffer members 204 and second buffer members 205 are arranged at intervals, and the empty parts just correspond to the positions of the arc grooves 203, so that the buffer members that are not installed will not affect the torsion of the cable body 1.

[0038] A filler 206 is filled between the insulating sleeve 208 and the support frame 201, and an outer sheath 103 is provided on the outer peripheral wall of the insulating sleeve 208.

The buffer component has the function of enhancing the cable body 1 to resist external pressure. During use, the multiple groups of buffer parts installed inside can buffer the pressure generated by the outside world, so that the internal buffer parts are squeezed and deformed to generate resistance elastic force, which can enhance the ability of the cable to resist and relieve external pressure.

[0039] The inner peripheral wall of the outer sheath 103 is fixedly connected with the protective sheath 102. The buffer assembly includes:

[0040] A first buffer member 204 connected to the inner wall of the insulating sleeve 208;

[0041] A second buffer member 205 connected to the outer peripheral wall of the protective sleeve 102;

[0042] The first buffer member 204 and the second buffer member 205 are arranged at intervals, the first buffer member 204 and the second buffer member 205 are arranged alternately, and a buffer gap 207 is formed between the first buffer member 204 and the second buffer member 205 .

[0043] In summary, compared with the prior art, the present invention has the following beneficial effects: by providing a cross support frame 201 at the cable core 101 and a reinforcing column 202 on the outer wall of the cross support frame 201, the internal buffer can buffer the pressure generated by the outside world, so that the internal buffer can be squeezed and deformed to generate a resisting elastic force, thereby enhancing the ability of the cable to resist and relieve the external pressure, thereby improving the supporting and compressive resistance of the cable body 1. At the same time, the outer peripheral wall of the support frame 201 is provided with an arc groove 203, which can make the cable body 1 twist along the direction of the arc groove 203 during the twisting process, making it easy to twist and preventing the cable body 1 from breaking during a long period of twisting, thereby improving the service life of the cable body 1.
