DETAILED DESCRIPTION

[0022] The following is a detailed description of a cable for military equipment provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a cable for military equipment, including: a cable core sleeve 1, an armor 6 is sleeved on the outer side of the cable core sleeve 1, a protective sleeve 2 is sleeved on the outer side of the armor 6, a connecting sleeve 3 is threadedly connected to one side of the protective sleeve 2, a fastening sleeve 4 is symmetrically installed on one side of the connecting sleeve 3, the fastening sleeve 4 and the connecting sleeve 3 are threadedly connected, and magnetic blocks 7 are respectively installed inside the protective sleeve 2 and inside the connecting sleeve 3, and the magnetic blocks 7 are evenly installed along the bottom of the cable core sleeve 1 and the top of the inner cavity of the connecting sleeve 3, and are attracted to each other;

[0024] When the cables need to be spliced, the cables are passed through the inside of the fastening sleeve 4 and the connecting sleeve 3 in turn, and the fastening sleeve 4 is twisted to rotate and engage the threads between the connecting sleeve 3 and the fastening sleeve 4, and the magnetic suction block 7 at the bottom of the protective sleeve 2 and the magnetic suction block 7 at the top of the connecting sleeve 3 are attracted to each other, thereby fixing the installation position of the cable, improving the stability of the cable splicing, and avoiding the cable splicing from shaking and causing separation, which affects the use. The setting of this structure makes the cable splicing more convenient, more stable, and safer, and improves the practicality during use;

[0025] The magnetic attraction block 7 includes but is not limited to structures such as magnets that can attract each other.

[0026] In this embodiment, if Figure 3As shown, the outer side of the armor 6 is provided with a protective layer 10, which is in the shape of a honeycomb cavity and is evenly attached to the outer side of the cable core sleeve 1 to reduce the overall weight of the cable. The inner cavity of the protective layer 10 is filled with a flame retardant. When an open flame is generated, the high temperature causes the gas inside the cavity of the protective layer 10 to react violently and expand. When the cavity expands to a critical value, it ruptures and releases the flame retardant inside the cavity of the protective layer 10, thereby preventing the burning cable from causing the spread of fire.

[0027] The cavity inside the protective layer 10 is filled with gas, which includes but is not limited to air, carbon dioxide and other gases that expand when heated.

[0028] In this embodiment, if Figure 2 and Figure 3 As shown, a mounting ring 11 is fixed to the bottom of the armor 6, and a magnetic block 7 inside the protective sleeve 2 is fixed to the bottom of the mounting ring 11. The inner wall of the protective sleeve 2 is provided with an insulating layer and a shielding layer in sequence. The insulating layer is in contact with the surface of the protective layer 10. The insulating layer is provided to prevent the cable from causing leakage hazards. The shielding layer is provided to effectively shield the interference of external electric and magnetic fields, thereby ensuring fast signal transmission speed.

[0029] In this embodiment, if Figure 2 As shown, the inner wall of the connecting sleeve 3 is provided with a water-absorbing cavity 8, and the interior of the water-absorbing cavity 8 is filled with water-absorbing material, which effectively prevents the connecting sleeve 3 from generating water vapor in areas with a large temperature difference between day and night, causing the phenomenon of cable leakage. The connecting sleeve 3 is made of fire-proof material, and the outer sides of the protective sleeve 2 and the connecting sleeve 3 are engaged and rotated with rollers 5. By setting the rollers 5, when the cable is dragged for installation at other positions, the protection is increased to prevent the installation personnel from dragging and causing wear of the cable. The inside of the fastening sleeve 4 symmetrically installed on one side of the connecting sleeve 3 is evenly provided with extrusion sleeves 9, which are made of elastic material. The fastening sleeves 4 symmetrically installed on one side of the connecting sleeve 3 are fixed by bolts, and the extrusion sleeves 9 fix the cable located inside the fastening sleeve 4 in a opposite direction to prevent the cable from being damaged by excessive tightening of the bolts during installation.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
