Description

Technical Field

[0001] The utility model is a bending-resistant soft cable, belonging to the technical field of cables. Background Art

[0002] Cables can be divided into power cables, communication cables and control cables according to their uses. They are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and are often twisted around a center wire. The entire outer layer is covered with a highly insulating covering. They are mostly installed in the air or underground or underwater for telecommunications or power transmission. Cables in real life are prone to frequent bending and movement when used in industrial environments. How to ensure the high flexibility and bending resistance of cables is a topic discussed in the industry. However, general cables have certain disadvantages in terms of high flexibility and bending resistance in actual use. They are usually bent only with the help of the cable material itself. As time goes by and the cable ages and wears, the bending resistance will be reduced, and the reliability of use is insufficient.

[0003] Chinese patent number: CN213635419U, mentions a soft, bend-resistant, flame-retardant cable. Through structural improvements and innovative layout, the device can make the cable itself have good bending resistance when actually used, while maintaining a certain degree of softness, so that the device will not reduce the bending resistance of the cable with the passage of time and aging and wear of the cable. It has strong reliability in use and good heat dissipation, and is suitable for popularization and use. However, the protective inner shell and outer shell of this device are not easy to disassemble, and it is not convenient to repair or replace the cable. Now there is an urgent need for a bend-resistant, soft cable to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a bending-resistant soft cable to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure and good practicality. By setting a snap-fit ​​structure, it is easy to disassemble and assemble the cable, making replacement or maintenance more convenient. At the same time, it has certain bending resistance and heat dissipation effects, and has high reliability in use.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a bending-resistant soft cable, comprising an outer protective sleeve and a cable, a rectangular block is symmetrically installed on the right end of the annular side of the outer protective sleeve, two of the rectangular blocks respectively penetrate the outer protective sleeve, and the two rectangular blocks are respectively penetrated with a thread groove on the relative outer sides, and a screw is respectively screwed in the two thread grooves, and a knob is respectively sleeved on the annular side of the two screws, a plurality of U-shaped rubber blocks are equidistantly installed on the circumference of the inner ring surface of the outer protective sleeve, and a plurality of first heat dissipation holes are respectively penetrated above the plurality of U-shaped rubber blocks, a cable sleeve is sleeved on the annular side of the cable, and a plurality of docking blocks are equidistantly installed on the circumference of the annular side of the cable sleeve, and a plurality of second heat dissipation holes are respectively opened above the plurality of docking blocks, and the plurality of docking blocks are made of soft material.

[0006] Furthermore, a limiting ring is installed on the left end of the outer protective sleeve through bolts.

[0007] Furthermore, a mounting ring is sleeved on the annular side surface of the limiting ring.

[0008] Furthermore, a cable connector is installed on the left side of the mounting ring.

[0009] Furthermore, the inner groove dimensions of the plurality of U-shaped rubber blocks are respectively larger than the dimensions of the plurality of docking blocks.

[0010] Furthermore, the two screw rods are hollow and cylindrical in shape, and are made of aluminum alloy.

[0011] The beneficial effects of the utility model: the utility model is a bending-resistant soft cable. Because the utility model adds an outer protective sleeve, a rectangular block, a screw, a U-shaped rubber block, a first heat dissipation hole and a second heat dissipation hole, our design improvement and actual use show that the device has a reasonable structure and good practicality. By setting a snap-fit ​​structure, it is easy to disassemble and assemble the cable, making replacement or maintenance more convenient. At the same time, it has certain bending resistance and heat dissipation effects, and has strong reliability in use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 5 The utility model provides a technical solution: a bending-resistant soft cable, including an outer protective sleeve 1 and a cable 15, a rectangular block 3 is symmetrically installed on the right end of the annular side of the outer protective sleeve 1, two rectangular blocks 3 respectively penetrate the outer protective sleeve 1, and the two rectangular blocks 3 are respectively penetrated with thread grooves 12 on the opposite outer sides, screws 4 are respectively screwed in the two thread grooves 12, and knobs 5 are respectively sleeved on the annular sides of the two screws 4, a plurality of U-shaped rubber blocks 6 are equidistantly installed on the circumference of the inner ring surface of the outer protective sleeve 1, and a plurality of first heat dissipation holes 11 are respectively penetrated above the plurality of U-shaped rubber blocks 6, a cable sleeve 13 is sleeved on the annular side of the cable 15, a plurality of docking blocks 7 are equidistantly installed on the circumference of the annular side of the cable sleeve 13, and a plurality of second heat dissipation holes 14 are respectively opened above the plurality of docking blocks 7, and the plurality of docking blocks 7 are made of soft material. This design solves the problem that the protective inner shell and the outer shell of the original device are not easy to disassemble and assemble, and it is inconvenient to repair or replace the cable.

[0021] As the first embodiment of the utility model: a limit ring 9 is installed at the left end of the outer protective sleeve 1 through a bolt 10. By setting the limit ring 9, it is convenient to limit the cable sleeve 13. The annular side of the limit ring 9 is sleeved with a mounting ring 8, and a cable connector 2 is installed on the left side of the mounting ring 8. By setting the cable connector 2, it is convenient to plug the cable 15. The inner groove dimensions of the multiple U-shaped rubber blocks 6 are respectively larger than the dimensions of the multiple docking blocks 7. By setting the inner groove dimensions of the multiple U-shaped rubber blocks 6 to be larger than the dimensions of the multiple docking blocks 7, it is convenient to smoothly insert the multiple docking blocks 7 into the inner grooves of the multiple U-shaped rubber blocks 6. The two screws 4 are respectively hollow and cylindrical, and the two screws 4 are respectively made of aluminum alloy. By adopting the hollow design of the two screws 4 to be cylindrical, it is convenient to use the good heat dissipation of aluminum alloy to achieve a certain heat dissipation effect on the cable 15.

[0022] As a second embodiment of the utility model: when in use, first align the cable sleeve 13 with the outer protective sleeve 1, and then insert the multiple docking blocks 7 into the multiple U-shaped rubber blocks 6 respectively, so that the cable sleeve 13 drives the cable 15 to rest against one side of the limit ring 9, and then at this time, by rotating the two knobs 5, the two screws 4 are rotated, so that the two screws 4 pass through the corresponding first heat dissipation holes 11 and enter the corresponding second heat dissipation holes 14, contacting the surface of the cable sleeve 13, which can limit the cable sleeve 13. When the cable 15 generates heat, the screw 4 will conduct and dissipate the heat, and the multiple second heat dissipation holes 14 and the multiple first heat dissipation holes 11 will play a role in auxiliary heat dissipation. There will be a certain gap between the outer side of the U-shaped rubber block 6 and the arc surface of the outer protective sleeve 1 for heat dissipation. When the cable 15 is bent, most of the bending force will be borne by the multiple U-shaped rubber blocks 6 and the multiple docking blocks 7.
