Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to an anti-aging flexible cable. Background Art

[0002] With the continuous development of informatization and industrialization, the application of industrial automation and intelligent manufacturing is becoming more and more extensive, and the demand for flexible cables is gradually increasing. It has become the new darling of the wire and cable industry in recent years. Flexible cables are the preferred cables for power transmission materials and signal transmission carriers in drag chain motion systems.

[0003] When existing flexible cables are used in a relatively humid environment, they will accelerate aging and corrosion due to the high water content in the air, especially at the connection position between cables, which easily exposes the live wires to the air, causing leakage or short circuit. When multiple turns of cables are laid, corrosion is easily caused between the cables, causing damage to multiple cables at the same time.

[0004] To solve the above problems, we propose an anti-aging flexible cable. Summary of the invention

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an anti-aging flexible cable, comprising a cable body, the cable body is composed of an annular rubber protective layer, a waterproof and moisture-proof layer, a steel wire armor layer and a plurality of cable cores from the outside to the inside, a heat-conducting core is arranged in the middle of the rubber protective layer, a desiccant is filled in the waterproof and moisture-proof layer, an isolation plastic is filled between the steel wire armor layer and the cable core, both ends of the cable body are sleeved with connecting blocks with a regular hexagonal cross-section on the outside, the connecting blocks are bonded to the cable body by glue, and three sockets are opened horizontally on each of the connecting blocks, which are located at the same The three sockets on a connecting block are evenly distributed circumferentially and arranged parallel to the outer wall of the corresponding connecting block. The sockets on the two connecting blocks are staggered, and a sealing plug plate is penetrated and slidably connected in each of the sockets. The three sealing plug plates on the same connecting block are commonly fixedly connected with an annular push piece at one end away from the end of the cable body. The cross-section of each sealing plug plate is an isosceles trapezoidal structure, and a sealing groove is provided on the corresponding surface in the clockwise direction of each sealing plug plate, and a sealing slider matching the sealing groove is fixedly connected to the corresponding surface in the counterclockwise direction of each sealing plug plate.

[0007] In the above-mentioned anti-aging flexible cable, the material of the rubber protective layer is flame-retardant rubber.

[0008] In the above-mentioned anti-aging flexible cable, the contact surface between the isolation plastic and each cable core is painted with conductive paint.

[0009] In the above-mentioned anti-aging flexible cable, a plurality of fluorescent wires evenly distributed in a circumference are embedded in the isolation plastic, and the fluorescent wires contain fluorescent liquid.

[0010] In the above-mentioned anti-aging flexible cable, the six surfaces of the outer end of the connection block are fixedly connected with splicing blocks, and the six surfaces are provided with splicing grooves corresponding to the splicing blocks.

[0011] In the above-mentioned anti-aging flexible cable, each sealing plug plate is fixedly connected with a card block at one end away from the push piece, and a card groove matching the card block is provided on the end surface of the connection block away from the push piece and at the middle position of each two adjacent sockets.

[0012] Compared with the existing technology, the advantages of this anti-aging flexible cable are:

[0013] By setting the connecting block, during the cable connection process, it is only necessary to sleeve and fix the connecting block on the end of the cable body, and after connecting the two cable body connection ends, push the two push pieces close to the connection position, and the sealing plug plates on the left and right positions move closer, and a total of six sealing plug plates on the left and right sides will form a closed hexagonal prism to wrap the connection position of the two cable bodies, and the sealing sliders on each sealing plug plate are all entered into the corresponding sealing slide grooves, which have good waterproof sealing and effectively protect the cable joints.

[0014] When arranging multiple groups of cables, there is no need to use additional separators. You only need to use connecting blocks to splice the cables to ensure a certain distance between the cables, ensure the normal operation of the cables, and prevent water accumulation, thereby improving the anti-aging performance.

DETAILED DESCRIPTION

[0019] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0020] Example

[0021] Reference Figure 1-3 , an anti-aging flexible cable, including a cable body 1, the cable body 1 is composed of an annular rubber protective layer 2, a waterproof and moisture-proof layer 4, a steel wire armor layer 5 and a plurality of cable cores 7 from the outside to the inside, the material of the rubber protective layer 2 is flame-retardant rubber, which has good flame retardancy, and a heat-conducting core 3 is arranged in the middle of the rubber protective layer 2, which has a heat conduction effect, increases the thermal conductivity of the cable, and makes the cable have high temperature resistance. The waterproof and moisture-proof layer 4 is filled with a desiccant, which can effectively prevent moisture from entering the cable and causing damage to the cable core 7 after the rubber protective layer 2 is damaged. The steel wire armor layer 5 can improve the hardness of the cable and protect the internal cable core 7 to prevent it from breaking easily. The isolation plastic 6 is filled between the steel wire armor layer 5 and the cable core 7, and the contact surface between the isolation plastic 6 and each cable core 7 is brushed with conductive paint, which can form an electromagnetic shielding, thereby preventing electromagnetic interference between adjacent cable cores 7. A plurality of fluorescent wires 8 evenly distributed in a circumference are embedded in the isolation plastic 6. The fluorescent wires 8 contain fluorescent liquid. When the cable body 1 breaks and the break position affects the cable core 7, the fluorescent wires 8 will definitely break, thereby flowing out the fluorescent liquid, making it convenient for the staff to carry out maintenance work.

[0022] The outer sides of both ends of the cable body 1 are sleeved with a connecting block 9 with a regular hexagonal cross section. The connecting block 9 and the cable body 1 are bonded by glue. Three sockets are opened horizontally on each connecting block 9. The three sockets on the same connecting block 9 are evenly distributed circumferentially and arranged parallel to the outer wall of the corresponding connecting block 9. The sockets on the two connecting blocks 9 are staggered. A sealing plug 10 is penetrated and slidably connected in each socket. The three sealing plugs 10 on the same connecting block 9 are fixedly connected to a circular push piece 11 at one end away from the end of the cable body 1. The push piece 11 can push the three corresponding sealing plugs 10 to move at the same time. The cross section of each sealing plug 10 is an isosceles trapezoidal structure. A sealing slide groove 12 is opened on the corresponding surface of each sealing plug 10 in the clockwise direction, and a sealing slider 13 matching the sealing slide groove 12 is fixedly connected on the corresponding surface of each sealing plug 10 in the counterclockwise direction.

[0023] Specifically, when the cable is connected, the end plates of the two cable bodies 1 are fixed with the connection block 9 in advance, and then the two cable bodies 1 are connected. Then, the two push pieces 11 near the connection position are pushed, and the sealing plugs 10 at the left and right positions are moved closer. A total of six sealing plugs 10 on the left and right sides will form a closed hexagonal prism, wrapping the connection position of the two cable bodies 1, and the sealing sliders 13 on each sealing plug 10 are all drawn into the corresponding sealing slide groove 12, which has good waterproof sealing. Each sealing plug 10 is fixedly connected with a card block 14 at one end away from the push piece 11, and there are card grooves 15 matching the card block 14 on the end surface of the connection block 9 away from the push piece 11 and at the middle position of each two adjacent sockets. When the sealing plugs 10 at the left and right positions are completely spliced, each card block 14 is inserted into the corresponding card groove 15, and the friction force is used to position the sealing plug 10. Only by using a large pulling force can the sealing plugs 10 on both sides be pulled apart again. It plays an effective role in protecting and guarding the cable joints, does not require manual winding of protective cloth, avoids leakage and corrosion, and greatly increases the service life of the flexible cable.

[0024] The six surfaces of the outer end of the connecting block 9 are fixedly connected with the splicing blocks 16, and the six surfaces are provided with splicing grooves 17 corresponding to the splicing blocks 16. By setting the splicing blocks 16 and the splicing grooves 17, the connecting block 9 can arrange multiple groups of cables without the need for additional separators. It only needs to use the connecting block 9 to splice the cables to ensure a certain distance between the cables, ensure the normal operation of the cables, and is not easy to accumulate water, thereby improving the anti-aging performance.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
