[0002] Cables used in aerospace are not only found on aircraft, but also in ground command centers. Due to the environmental factors of the ground command center, the cables used on the ground must also have normal power supply and communication (digital signals, analog signals) functions even when subjected to large tensile stress.

[0003] According to the disclosure (announcement) number: CN219832249U, disclosure (announcement) date: 2023-10-13, a flame-retardant and high-temperature resistant wire and cable for aerospace is disclosed.

[0004] In the prior art including the above-mentioned patent, the communication cables of the ground command will inevitably be bent during actual routing, and even bends in some places, which will increase the stress of the cables at that place, easily damage the cable conductors, and affect the normal communication of the cables. Summary of the invention

[0005] The purpose of the present invention is to provide a torsion-resistant, electromagnetic radiation-resistant, low-attenuation, and phase-stable signal cable for aviation use, aiming to solve the above-mentioned problems.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] An aviation-use torsion-resistant, electromagnetic-radiation-resistant, low-attenuation, phase-stable signal cable comprises a cable provided with a conductor, and also comprises an armor ring provided outside the conductor and arranged in a spiral pattern, wherein a compression-resistant part is provided in the cable, and the compression-resistant part is divided into an elastic sheet and a pressure plate according to its function;

[0008] The elastic sheet is bent to drive the pressure plate to move radially and squeeze the outer diameter of the armor ring, so that the inner diameter of the armor ring is reduced to form an inner ring, and an outer ring and a platform ring that are symmetrically arranged on both sides of the inner ring.

[0009] Preferably, it also includes a radiation-proof metal layer arranged on the outside of the armor ring, and the elastic sheet under deformation contacts the radiation-proof metal layer.

[0010] Preferably, an insertion rod which is plugged into and matched with the table ring is fixedly mounted on the elastic sheet.

[0011] Preferably, a plurality of positioning frames are slidably arranged on the table ring, and the positioning frames are divided into guard frames and connecting rods according to their functions, and the guard frames are slidably matched with the wires.

[0012] Preferably, the ring pulls the plurality of guard frames away from each other.

[0013] Preferably, the end of the connecting rod is provided with a terminal, and the terminal is pushed and driven by an elastic sheet to make the protective frame move toward the cable deformation position.

[0014] Preferably, both sides of the protective frame are squeezed by the connecting rod to be deformed and convex, and the convex arc tops are in contact with the adjacent wires.

[0015] Preferably, the two sides of the guard frame are deformed and reset so that the end is fixed to the elastic sheet.

[0016] Preferably, a protrusion matching with the table ring is fixedly mounted on the insertion rod, so that the elastic sheet and the table ring are combined to limit the movement of the inner ring.

[0017] Preferably, the end head is provided with a clamping piece which engages with the protrusion.

[0018] In the above technical scheme, the present invention provides an aviation-use torsion-resistant, electromagnetic radiation-resistant, low-attenuation, stable-phase signal cable, which has the following beneficial effects: during the normal winding and transportation of the cable, the elastic armor ring is used to reduce the stress on the wire and ensure the use effect of the cable, and the elastic sheet is deformed by force during the bending process of the cable, and is transmitted to the pressure plate for pressing the armor ring, so that the armor ring is tightened and curled toward its axis to form an inner ring with a reduced pitch, and the outer ring has the same inner diameter as the armor ring, which is convenient for cutting the cable so that the incision can be made at the outer ring position, increasing the applicable range of the cable and ensuring the integrity of the bending position. Since the inner diameter of the inner ring is significantly smaller than the inner diameter of the outer ring, the drop between the outer ring and the inner ring is used to form a table ring with an increased pitch. Therefore, the inner ring has a significantly improved bending resistance compared to the outer ring, so that the bending position of the cable has a better stress resistance effect, and the pressure plate with a deformation effect can also reduce the stress at the inner ring position, strengthen the stress resistance of the cable, greatly reduce the stress damage problem of the wire, and improve the safety of cable use and communication effect.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-7 As shown, an aviation-use torsion-resistant, electromagnetic-radiation-resistant, low-attenuation, stable-phase signal cable comprises a cable 1 provided with a conductor 11, and also comprises an armor ring 2 provided outside the conductor 11 and arranged in a spiral shape, and a compression-resistant member 3 is provided in the cable 1, and the compression-resistant member 3 is divided into an elastic sheet 31 and a pressure plate 32 according to the function;

[0031] The elastic sheet 31 is bent to drive the pressing plate 32 to move radially and squeeze the outer diameter of the armor ring 2, so that the inner diameter of the armor ring 2 is reduced to form an inner ring 23, and an outer ring 21 and a platform ring 22 symmetrically arranged on both sides of the inner ring 23.

[0032] Specifically, the cable 1 and the conductor 11 are prior arts and are not elaborated here. The armor ring 2 is specifically an elastic metal strip, which has the ability to adapt to bending deformation after molding, and also has the function of further tightening and curling. During production, the conductor 11 is first arranged, and then a rubber layer is extruded on the conductor 11, and then the armor ring 2 is curled and wrapped around the rubber layer, and finally the outermost rubber layer is extruded. The purpose is to ensure that the armor ring 2 can be stably present in the cable 1 for use, thereby increasing the anti-bending effect of the cable 1.

[0033] Furthermore, when the cable 1 is produced, obvious markings are applied on its side walls. The purpose is that when the cable 1 needs to be bent for use, the bending position should be at the markings to maximize the protection of the conductor 11, and this position also has a separate chamber to provide space for the pressure plate 32 and the elastic sheet 31 to move.

[0034] Furthermore, the pressure-resistant parts 3 are arranged circumferentially on the outside of the armor ring 2, and a block connected to the elastic sheet 31 is fixedly installed on the pressure plate 32. The elastic sheet 31 is embedded in the rubber layer of the cable 1 except for the two ends, so that the elastic sheet 31 is deformed following the bending of the cable 1 to ensure that the elastic sheet 31 drives the pressure plate 32. The elastic sheet 31 and the pressure plate 32 are both made of elastic metal, but the deformation coefficient of the pressure plate 32 is greater than the deformation coefficient of the elastic sheet 31, so that the elastic sheet 31 is more susceptible to bending and deformation to generate driving force, and the pressure plate 32 is used to adapt to the bending of the position of the inner ring 23 to ensure the squeezing and covering effect of the inner ring 23.

[0035] Furthermore, after the cable 1 is bent, it has a bending depression and a bending ridge, and the elastic sheet 31 at the bending depression uses its arc top to push the pressure plate 32 to squeeze the armor ring 2, while the elastic sheet 31 at the bending ridge uses its adaptive deformation state and is forced to push the pressure plate 32 to move closer to the armor ring 2 to achieve extrusion, thereby ensuring that the armor ring 2 is squeezed and contracted.

[0036] During the normal winding and transportation of the cable 1, the elastic armor ring 2 is used to reduce the stress on the conductor 11 to ensure the use effect of the cable 1. During the bending process of the cable 1, the elastic sheet 31 is deformed by force and transmitted to the pressure plate 32 for pressing the armor ring 2, so that the armor ring 2 is tightened and curled toward its axis to form an inner ring 23 with a reduced pitch. The outer ring 21 has the same inner diameter as the armor ring 2, which is convenient for cutting the cable 1 so that the incision can be made at the position of the outer ring 21, thereby increasing the application range of the cable 1 and ensuring the integrity of the bending position. , and because the inner diameter of the inner ring 23 is significantly smaller than the inner diameter of the outer ring 21, the step between the outer ring 21 and the inner ring 23 is used to form a table ring 22 with an increased pitch. Therefore, the inner ring 23 has a significantly improved bending resistance compared to the outer ring 21, so that the bending position of the cable 1 has a better stress resistance effect, and the pressure plate 32 with a deformation effect can also reduce the stress at the position of the inner ring 23, strengthen the stress resistance of the cable 1, greatly reduce the stress damage problem of the conductor 11, and improve the safety of the cable 1 and the communication effect.

[0037] As an embodiment further provided by the present invention, it also includes a radiation-proof metal layer 12 arranged on the outside of the armor ring 2, and the deformed elastic sheet 31 is in conflict with the radiation-proof metal layer 12.

[0038] Specifically, the radiation-proof metal layer 12 is made of a metal material with radiation-proof material, in order to provide the conductor 11 with radiation-proof effect, and the radiation-proof metal layer 12 is segmented when reaching the bending position of the cable 1, in order to prevent the radiation-proof metal layer 12 from being easily damaged after the cable 1 is bent, and the lack of radiation-proof effect at this part of the position can be ignored.

[0039] Furthermore, the end of the radiation-proof metal layer 12 is located in the cavity where the elastic sheet 31 moves, and conflicts with the end of the radiation-proof metal layer 12 after the elastic sheet 31 is deformed, and the elastic sheet 31 contains a material with the same function as the radiation-proof metal layer 12 .

[0040] The elastic sheet 31 is bent and embedded in the arc groove of the cavity, so that the elastic sheet 31 is connected to the radiation protection metal layer 12, so that multiple elastic sheets 31 can make up for the partial radiation protection function missing at the bending position of the cable 1, increase the use effect of the cable 1, and make the cable 1 more complete, and improve the bending resistance of the cable 1.

[0041] As another embodiment further provided by the present invention, an insert rod 33 which is plugged into and matched with the table ring 22 is fixedly mounted on the elastic sheet 31 .

[0042] Specifically, the insertion rod 33 is fixedly installed at the end of the elastic sheet 31 , and the insertion rod 33 is driven by the deformation of the elastic sheet 31 to move toward the axis of the armor ring 2 .

[0043] Furthermore, a hole for inserting the insertion rod 33 is opened on the table ring 22, and the insertion position of the insertion rod 33 is located at the end of the larger bottom surface of the table ring 22 with a trapezoidal cross-section.

[0044] The inner ring 23 is formed by tightening and curling the armor ring 2 toward its axis (similar to twisting a towel with both hands), so that the two ends of the inner ring 23 move in a spiral direction, and in the process of the armor ring 2 forming the table ring 22, the end of the smaller bottom surface of the table ring 22 is pulled and twisted by the inner ring 23, so that the table ring 22 stores part of the tightening and curling force of the inner ring 23, and this process is accompanied by the insertion of the rod 33 into the end of the larger bottom surface of the table ring 22, so that the force stored in the table ring 22 is transmitted to the elastic sheet 31, and the torque generated when the cable 1 is arranged during the routing is at this time. The torque stored in the ring 22 offsets a part, thereby achieving the purpose of resisting the torsional force of the cable 1, reducing the wear on the side wall of the cable 1 caused by the torque, making the cable 1 safer to use after wiring and arrangement, and also ensuring the communication of the cable 1; but because the inner ring 23 will generate torsional forces in two directions, and the other torsional force cannot be used for offsetting work, the diffusion of the torsional force is limited when the cable 1 is bent, so that the torsional force continues to be used to reduce the pitch of the inner ring 23, so that the inner ring 23 is subjected to an additional tightening and curling effect, thereby increasing the stress resistance of the inner ring 23 to the conductor 11.

[0045] As another embodiment further provided by the present invention, a plurality of positioning frames 4 are slidably disposed on the table ring 22 . The positioning frames 4 are divided into a protective frame 41 and a connecting rod 42 according to their functions. The protective frame 41 is slidably matched with the wire 11 .

[0046] Specifically, a single conductor 11 is equipped with a positioning frame 4 symmetrically arranged with the inner circle 23 as the center, so that the two protective frames 41 can provide support for the conductor 11, and the positioning frame 4 is equidistantly arranged in the spiral direction on the table circle 22 to increase the supporting area of ​​the connecting rod 42 for the cable 1, and a cavity for the positioning frame 4 to move is also provided in the cable 1, so that the positioning frame 4 can more easily protect the conductor 11.

[0047] The staggered positioning frames 4 on the ring 22 provide support for the cross section of the cable 1, reducing the damage caused by external forces to the bending position of the cable 1, and the wire 11 protected by the protective frame 41 has higher safety. After the cable 1 is bent, the bending amplitude is likely to affect the position of the ring 22, so the multiple connecting rods 42 play an anti-bending function, increasing the stability of the wire 1 during operation.

[0048] As another embodiment further provided by the present invention, the ring 22 pulls the plurality of guard frames 41 away from each other.

[0049] Specifically, the connecting rod 42 is slidably disposed in a hole provided on the table ring 22 , so that the positioning frame 4 can move radially on the table ring 22 .

[0050] The increased pitch of the table ring 22 allows the positioning frames 4 thereon to be axially separated from each other, so as to increase the support and anti-bending area of ​​the positioning frames 4 for the wires 11, thereby making the wires 11 protected by the protection frame 41 safer and further reducing the damage to the wires 11 caused by stress.

[0051] As another embodiment further provided by the present invention, a terminal 43 is provided at the end of the connecting rod 42 , and the terminal 43 is pushed and driven by the elastic sheet 31 to make the protective frame 41 move toward the deformation position of the cable 1 .

[0052] Specifically, the connecting rods 42 are symmetrically arranged on the protective frame 41, and the cross section of the protective frame 41 is pill-shaped, and its two side walls are made of memory metal, while the arc-shaped pieces at both ends of the protective frame 41 are made of heat-conducting metal.

[0053] The elastic sheet 31 on the inner side of the recess of the cable 1 pushes the end 43 to move, so that the end 43 on the other side of the protective frame 41 actively approaches the bent and raised position of the cable 1, so that this part of the end 43 can be used to compensate for the increase in the area of ​​the bent and raised position of the cable 1, so that the positioning frame 4 can better diffuse the stress, reduce the bending of the cable 1 and cause the stress distribution to be uneven, and with the end 43 after movement close to the bent and raised part of the cable 1, the high temperature generated by the conductor 11 working in the bent state is transferred to the protective frame 41, and then transferred to the end 43 close to the side wall of the cable 1 through the connecting rod 42, effectively increasing the heat loss of the conductor 11 and reducing the temperature increase of the cable 1 caused by bending.

[0054] As another embodiment further provided by the present invention, both sides of the protection frame 41 are squeezed by the connecting rods 42 to be deformed and convex, and the convex arc tops are in contact with the adjacent wires 11.

[0055] Specifically, in the default state of the protective frame 41, one of the arc-shaped pieces fits the wire 11, and after the positioning frame 4 is driven to move, the other arc-shaped piece keeps fitting the wire 11. The purpose is that regardless of whether the cable 1 is bent or not, the protective frame 41 can transfer and diffuse the heat generated by the wire 11 during operation, thereby ensuring the safety of the wire 11 and the stability of communication.

[0056] After the end 43 of the bent bulge near the cable 1 has finished moving, the elastic sheet 31 that continues to move provides further extrusion to the driven end 43, and transmits force to the protective frame 41 so that both sides thereof are deformed and convex, and one of the arc-shaped sheets of the protective frame 41 remains in contact with the conductor 11, so that after the side of the deformed bulge is in contact with the remaining conductors 11, the heat generated by all the conductors 11 can be concentrated, and the heat is preferentially transferred to the end 43 through the connecting rod 42, thereby reducing the need for heat to be transferred through the rubber layer of the cable 1 and then to the connecting rod 42, so that the heat collected by the end 43 can be quickly transferred to the air through the side wall of the cable 1, thereby reducing the interference of high temperature on the operation of the cable 1.

[0057] As another embodiment further provided by the present invention, both sides of the protection frame 41 are deformed and reset so that the end 43 is fixed to the elastic sheet 31 .

[0058] By keeping the cable 1 in a bent state for a long time, the side of the protective frame 41 is heated and gradually recovers to a pill shape, and the driven end 43 is subjected to a reset force to push the elastic sheet 31 back, so that the connecting rod 42 and the elastic sheet 31 are gradually tightened, and the elastic sheet 31 recovers part of its deformation, thereby increasing the tension of the elastic sheet 31 and making the bent concave part of the cable 1 tighter, so as to adapt to the stress resistance stability of the cable 1 in a long-term bent state.

[0059] As another embodiment further provided by the present invention, a protrusion 34 matching with the table ring 22 is fixedly mounted on the insertion rod 33, so that the elastic sheet 31 is combined with the table ring 22 to limit the movement of the inner ring 23.

[0060] Specifically, the protrusion 34 is fixedly sleeved on the end of the insertion rod 33, and the diameter of the hole on the table ring 22 for the insertion of the insertion rod 33 is larger than the diameter of the protrusion 34, so that the insertion rod 33 after insertion is tilted due to the curvature of the elastic sheet 31, and the protrusion 34 provides a limit for the insertion rod 33, making the connection between the elastic sheet 31 and the table ring 22 more stable.

[0061] The deformed elastic sheet 31 is limited by the protrusion 34, so that the elastic sheet 31 forces the pressure plate 32 to cover and shield the inner ring 23. The purpose is that the cable 1 is in a bent state for a long time, and the temperature rise will make the metal armor ring 2 easy to be damaged, and because the inner ring 23 is driven by the bending to be tighter and more stress-resistant, the inner ring 23 will also become fragile. If the inner ring 23 breaks, the covering and shielding pressure plate 32 can protect the inner ring 23 to prevent the damage of the inner ring 23 from affecting the conductor 11, and the elastic sheet 31 also replaces part of the stress resistance of the inner ring 23, and the elastic sheet 31 and the table ring 22 and the outer ring 21 are integrated, so that after the armor ring 2 is damaged, the protection effect on the bending position of the cable 1 can still be maintained, thereby ensuring the high efficiency of the long-term bending work of the cable 1.

[0062] As another embodiment further provided by the present invention, a clamping member 44 is disposed on the end head 43 and is engaged with the protrusion 34 .

[0063] Specifically, the clamp 44 is an elastic metal frame, and the end face is "U"-shaped, and the inner side of the clamp 44 has a hemispherical depression, so that the protrusion 34 can be firmly embedded in the depression, and the locking protrusion 34 can be easily engaged to ensure the stability of the elastic sheet 31 after locking.

[0064] The protrusion 34 is sent into the hole on the table ring 22 by the radially moving insertion rod 33, and then the movable positioning frame 4 actively plugs and assembles the clamping member 44 with the insertion rod 33, and the protrusion 34 is embedded in the hemispherical recess on the inner side of the clamping member 44 to be fixed, so that the insertion rod 33 is axially locked, and the deformed elastic sheet 31 can be fixed, so that the elastic sheet 31 used as a protective inner ring 23 can firmly maintain the replacement function, effectively increasing the safety of the cable 1 after damage.

[0065] Working principle: During the normal winding and transportation of the cable 1, the elastic armor ring 2 is used to reduce the stress on the conductor 11 to ensure the use effect of the cable 1, and the elastic sheet 31 is deformed by force during the bending process of the cable 1, and the force is transmitted to the pressure plate 32 to press the armor ring 2, so that the armor ring 2 is tightened and curled toward its axis to form an inner ring 23 with a reduced pitch, and the outer ring 21 has the same inner diameter as the armor ring 2, which is convenient for cutting the cable 1 so that the incision can be made at the position of the outer ring 21, thereby increasing the application range of the cable 1, and because the inner diameter of the inner ring 23 is significantly smaller than the inner diameter of the outer ring 21, the drop between the outer ring 21 and the inner ring 23 is used to form a table ring 22 with an increased pitch, so the inner ring 23 has a significantly improved bending resistance compared to the outer ring 21, so that the bending position of the cable 1 has a better stress resistance effect, and the elastic sheet 31 is embedded after bending. In the arc groove of the cavity, the elastic sheet 31 is connected to the radiation-proof metal layer 12, so that the multiple elastic sheets 31 can make up for the partial radiation-proof function missing at the bending position of the cable 1, and the two ends of the inner ring 23 move in a spiral direction, and in the process of the armor ring 2 forming the table ring 22, the end of the smaller bottom surface of the table ring 22 is pulled and twisted by the inner ring 23, so that the table ring 22 stores part of the tightening curling force of the inner ring 23, and this process is accompanied by the insertion of the rod 33 into the end of the larger bottom surface of the table ring 22, so that the force stored in the table ring 22 is transmitted to the elastic sheet 31, and the torque generated when the cable 1 is arranged during routing is partially offset by the torque stored in the table ring 22 at this time, thereby achieving the purpose of anti-torsion force of the cable 1, reducing the wear on the side wall of the cable 1 caused by the torque, and making the cable 1 safer to use after routing.

[0066] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
