They are suitable for electrical equipment and instrument lines in the aviation industry, electronics industry and other high temperature conditions. Aviation cables have small outer diameter, light weight, wide operating temperature range, oil resistance, wear resistance, acid and alkali resistance and various chemical reagent corrosion resistance, aging resistance, high temperature resistance, vibration resistance, impact resistance, easy installation, non-combustibility and other properties.

[0019] According to the above technical solution, the interior of the storage bag is filled with thermal grease, the end of the contact metal block is in contact with the thermal block, and the buffer pad wraps the top and bottom of the storage bag.

[0020] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0021] 1. A splicing support mechanism is provided. The upper and lower fitting panels can be fixed to the top and bottom of the rubber surface layer by means of locking metal sheets and locking sides, which provides great convenience for workers to stack adjacent flat cables when installing and using cables. The upper and lower fitting panels of the cables at the upper and lower positions correspond to each other, and the splicing metal strips are embedded in the splicing grooves, and then the magnetic blocks are used to adsorb and fix them. The magnetic connection strength between them is further enhanced, making the cables more stable during stacking and use without mixing and cluttering, which provides great convenience for subsequent workers to find corresponding cables;

[0022] At the same time, the installation method using the upper and lower fitting panels is simple, and the locking side plays a role in limiting and stabilizing. The locking metal sheet can be embedded in the groove after being pressed and deformed, and fits and limits the rubber surface to fix it, providing the staff with a variety of cable installation options. When it is necessary to save space for stacking flat aviation cables, the corresponding upper and lower fitting panels are installed, and separately installed cables do not need to be used, which makes it more applicable and flexible.

[0023] 2. The left supporting bent plate and the right supporting bent plate are used to support and protect the cable from above. The embedded block increases the connectivity of the left supporting bent plate and the right supporting bent plate, so that they are placed on the outside of the rubber surface after splicing to prevent foreign objects from rolling and hitting in the external environment from causing deformation of the cable or damage to the internal core. The left supporting bent plate and the right supporting bent plate can be directly spliced ​​on the outside of the cable from both sides. The installation method is simple. They are embedded in the installation groove and will not affect the stacking of the cables up and down. At the same time, when the cables are stacked, the left supporting bent plate and the right supporting bent plate of the cables in the upper and lower positions correspond to each other, so that the lower protrusion contacts the upper protrusion for support and protection, thereby improving the compression resistance of the cable.

[0024] 3. A multi-directional protection mechanism is provided, and the arc-shaped support block and the arc-shaped pressing block are used to separate and stabilize the core. When the cable is installed, the core is placed on the arc-shaped support block, so that the cores maintain a certain distance from each other to prevent the cores from being squeezed and close to each other, affecting the subsequent normal use;

[0025] The metal thin-walled frame shapes the outside of the core body, so that the upper pressure pad and the arc-shaped pressing block will not detach. At the same time, it monitors the operation of the core body. The guide core is connected to the external current detection equipment. When an arc penetrates inside the cable, the core body will generate current radiating outward, and the partition blocks separate the core bodies from each other to prevent the generated arcs from affecting each other. After the arc penetrates, it is guided by the metal thin-walled frame and transmitted to the guide core through the arc-shaped metal seat. When the arc has not completely passed through the cable, it will be captured in time by the external detection equipment, and timely maintenance can be carried out before the arc spark occurs, thereby improving the safety of cable use.

[0026] 4. Multiple storage bags are fixed inside the cable and surround the outside of the core, which can absorb the heat generated by the core during operation. The thermal grease inside the storage bag can absorb the heat and transfer it through the contact metal block. Two thermal blocks are used to transfer the heat outward, so that the heat gradually moves away from the core, which plays a role of thermal insulation and protection for the core, preventing the core from continuously generating heat that cannot be dissipated outward and causing the internal temperature of the cable to be too high. The buffer pad plays a role of buffering and protecting the storage bag, absorbing the pressure transmitted from the outside, so that the storage bag will not be subjected to severe impact, and prevent the storage bag from being squeezed and ruptured.

[0027] In summary, by combining the splicing support mechanism with the multi-directional protection mechanism, the cable is protected from multiple aspects, such as increasing the structural strength of the cable and improving the safety of the core body, so that the cable will not be easily damaged during use, thereby increasing the service life of the cable and increasing the safety of the cable when used on aircraft.

[0049] A multi-directional protection mechanism 6 is installed on the inner side of the rubber frame 3;

[0050] The multi-directional protection mechanism 6 includes an arc-shaped support block 601, a partition block 602, an upper pressure pad 603, an arc-shaped pressing block 604, a metal thin-wall frame 605, an arc-shaped metal seat 606, a flow guide core 607, a protective layer 608, a storage capsule 609, a contact metal block 610, a card slot 611, a heat conduction block 612 and a buffer pad 613;

[0051] The bottom of the rubber frame 3 is fixedly installed with arc-shaped support blocks 601 at equal intervals, the middle of the rubber frame 3 is fixedly installed with spacers 602 at equal intervals, the top of the rubber frame 3 is covered with an upper pressure pad 603, and the bottom of the upper pressure pad 603 is fixedly connected with arc-shaped pressing blocks 604 at equal intervals. The number of arc-shaped support blocks 601 and spacers 602 is the same as the number of core body 1. The arc-shaped pressing blocks 604 are pressed on the top of the arc-shaped support blocks 601. The arc-shaped support blocks 601 and the arc-shaped pressing blocks 604 clamp the core body 1. The surface of the rubber frame 3 is sleeved with a metal thin-walled frame 605, and the middle of the top of the metal thin-walled frame 605 is fixedly installed with an arc-shaped metal seat 604 at equal intervals. 6. A guide core 607 is installed on the top of the arc-shaped metal seat 606. The surface of the guide core 607 is wrapped with a protective layer 608. The bottom of the surface of the protective layer 608 is equidistantly provided with notches. The arc-shaped metal seat 606 corresponds to the notches. The arc-shaped metal seat 606 covers the notches. The top of the arc-shaped metal seat 606 fits with the bottom of the surface of the guide core 607. Storage capsules 609 are installed at both ends of the top and bottom of the inner side of the rubber surface layer 4. A contact metal block 610 is fitted on one end of the storage capsule 609. Slots 611 are opened inside the two ends of the rubber surface layer 4. Heat-conducting blocks 612 are embedded and installed inside the slots 611.

[0052] The gap inside the rubber surface layer 4 is filled with a buffer pad 613, the interior of the storage capsule 609 is filled with thermal grease, the end of the contact metal block 610 is fitted with the thermal block 612, the buffer pad 613 wraps the top and bottom of the storage capsule 609, and the arc-shaped support block 601 and the arc-shaped pressing block 604 are used to separate and stabilize the core body 1. When the cable is installed, the core body 1 is placed on the arc-shaped support block 601, so that the core bodies 1 maintain a certain distance from each other, to prevent the core bodies 1 from being squeezed and close to each other to affect the subsequent normal use;

[0053] The metal thin-wall frame 605 shapes the outer side of the core 1, so that the upper pressure pad 603 and the arc-shaped pressing block 604 will not separate, and at the same time monitors the operation of the core 1. The current guide core 607 is connected to the external current detection equipment. When an arc penetrates inside the cable, the core 1 will generate current to radiate outward, and the separation block 602 separates the cores 1 from each other to prevent the generated arcs from affecting each other. After the arc penetrates, it is guided by the metal thin-wall frame 605 and transmitted to the current guide core 607 through the arc-shaped metal seat 606. When the arc does not completely pass through the cable, it is captured by the external detection equipment in time, and timely maintenance is performed before the arc spark occurs, thereby improving the safety of cable use.

[0054] A plurality of storage capsules 609 are fixed inside the cable and surround the outside of the core body 1, so as to absorb the heat generated by the core body 1 during operation. The thermal grease inside the storage capsule 609 can absorb the heat and transfer it through the contact metal block 610. The two thermal blocks 612 transfer the heat outward so that the heat gradually moves away from the core body 1, thereby providing thermal insulation and protection for the core body 1, preventing the core body 1 from continuously generating heat that cannot be dissipated outward and causing the internal temperature of the cable to be too high. The buffer pad 613 provides buffering and protection for the storage capsule 609, absorbing the pressure transmitted from the outside, preventing the storage capsule 609 from being subjected to severe impact, and preventing the storage capsule 609 from being squeezed and ruptured.

[0055] The working principle and use process of the present invention are as follows: first, the surface of the core body 1 is extruded and sleeved with an insulating layer 2, and the number of the core bodies 1 and the arc-shaped support blocks 601 is the same. Four core bodies 1 are placed in the middle of the arc-shaped support block 601 in sequence, and the upper pressure pad 603 is placed on the top of the rubber frame 3. The upper pressure pad 603 is a hard rubber pad, so that the arc-shaped pressing block 604 is pressed on the top of the core body 1 in sequence. The arc-shaped support block 601 and the arc-shaped pressing block 604 are both made of polymer plastic. The two ends of the bottom of the arc-shaped pressing block 604 are respectively fitted with the two ends of the top of the arc-shaped support block 601, clamping and fixing the core bodies 1, so that the core bodies 1 are separated from each other, which plays a role in limiting and stabilizing the core bodies 1, and the metal thin-walled frame 605 is sleeved on the surface of the rubber frame 3 and the upper pressure pad 603, and the arc-shaped metal seat 606 contacts the guide core 607 to support and fix it, and the end of the guide core 607 is connected to the external current monitoring equipment;

[0056] According to the installation and laying of the cable, the cable is placed on the installation plane, and the corresponding left support bent plate 511 and right support bent plate 512 are taken. When the flat cable is installed, it is laid flat on the ground. The two sides of the cable are respectively pressed against the surface of the rubber surface layer 4. The tops of the left support bent plate 511 and the right support bent plate 512 are both inserted into the installation groove 510, and the embedded block 513 at the end of the right support bent plate 512 is inserted into the end of the left support bent plate 511, so that the two are spliced ​​and fixed to each other. The left support bent plate 511 and the right support bent plate 512 protect the cable. When squeezed and collided by foreign objects, they will directly contact the left support bent plate 511 and the right support bent plate 512, and will not affect the core body 1 inside the cable.

[0057] If there are a large number of cables, they need to be stacked, which is more tidy, saves space and is convenient for subsequent identification and maintenance. Take the corresponding upper bonding panel 502 and lower bonding panel 503 and install them on the cables located below and above the stack respectively. The upper bonding panel 502 and lower bonding panel 503 are respectively tightly attached to the top and bottom ends of the rubber surface layer 4, and the locking side edges 504 on both sides are fitted with the edges of the rubber surface layer 4, so that the upper bonding panel 502 and the lower bonding panel 503 correspond to each other and will not be skewed. Press and bend the locking metal sheet 505. The locking metal sheet 505 is a pressable and deformable metal with a certain deformation ability, so that it is bent and embedded in the interior of the groove 501, which plays a fixing role on the upper bonding panel 502 and the lower bonding panel 503, and thus it will not easily fall off from the surface of the rubber surface layer 4. The cable installed with the lower bonding panel 503 is placed on the top of the cable installed with the upper bonding panel 502, and the lower bonding panel 503 is fixed. The splicing surface 506 at the bottom is tightly fitted with the upper bonding panel 502, and the splicing metal strip 509 is embedded in the interior of the splicing groove 507. The magnetic block 508 adsorbs and fixes the splicing metal strip 509, so that the lower bonding panel 503 and the upper bonding panel 502 are more stable. At the same time, the connectivity of the upper and lower cables is stronger and will not be misplaced. When the cables are stacked, the left support bent plate 511 and the right support bent plate 512 are inserted into the installation groove 510 through the through hole 516. The upper left support bent plate 511 and the right support bent plate 512 correspond to the positions of the lower left support bent plate 511 and the right support bent plate 512, and then the lower protrusions 515 on both sides of the upper cable are fitted with the upper protrusions 514 on both sides of the lower cable, and at the same time play a supporting and protective role. If the cable is installed separately in a certain environment, there is no need to stack multiple cables, that is, there is no need to install the upper bonding panel 502 and the lower bonding panel 503;

[0058] When the cable is in use, the core 1 will generate heat as it continues to operate. The heat is transferred outward and absorbed and transferred by the thermal grease inside the storage capsule 609. After the heat is absorbed to a certain extent, it is transferred to the edge to the thermal block 612 through the contact metal block 610. The multiple transfers of heat dissipation improve the heat dissipation effect, so that the temperature of the core 1 will not be too high. The buffer pad 613 is a silicone soft pad, which wraps the storage capsule 609 and plays a buffering and protective role on the storage capsule 609, so that it will not be squeezed and broken. In addition, the cable is used for a long time, and its internal parts are aged, and the core The current transmitted by the core 1 is likely to generate an arc outward, which passes through the insulating structure and causes the cable to be unable to be used normally. If the arc generated by the core 1 penetrates the insulating layer 2 on its surface and is transmitted outward, the partition block 602 is made of a polymer fiber material, which isolates the cores 1 so that the arcs will not affect each other. The arc is transmitted outward to the metal thin-wall frame 605, and the current is transmitted, passing through the arc-shaped metal seat 606 to the guide core 607, and then captured by the current monitoring equipment connected to the guide core 607, so that the staff can maintain and replace the cable in time.
