Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a stable amplitude and phase cable resistant to bending deformation and its manufacturing process. Background Technology

[0002] In numerous cable applications, such as aerospace, precision instrument connections, and high-frequency communications, the performance requirements for cables are extremely stringent. Cables not only need stable electrical properties to ensure accurate signal transmission and low loss, achieving stable amplitude and phase transmission, but also require excellent resistance to bending deformation.

[0003] In practical use, cables inevitably bend under various external forces, especially when frequently bent or subjected to large local forces, which can easily damage the internal structure of the cable. For example, the conductor may deform due to excessive bending, leading to increased resistance; the dielectric layer may crack or delaminate, affecting insulation performance; and the integrity of the shielding layer may be compromised, reducing its shielding effect. This deteriorates the electrical performance of the cable, causing problems such as increased signal attenuation and phase shift, seriously affecting the normal operation of the entire system.

[0004] Existing conventional cables are often designed primarily to meet basic electrical connection requirements, with insufficient consideration given to resistance to bending deformation. They typically employ a single or simple multi-layered structure to protect the internal conductors and achieve electrical functions, lacking specific reinforcement designs for bending resistance. When faced with complex operating environments and frequent bending operations, they struggle to effectively resist the damage caused by bending and cannot meet the demands of applications requiring extremely high cable performance stability. Therefore, developing a cable with excellent resistance to bending deformation and the ability to maintain stable amplitude and phase characteristics is of significant practical importance. Summary of the Invention

[0005] The purpose of this invention is to provide a stable amplitude and phase cable resistant to bending deformation and its manufacturing process, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bending deformation resistant amplitude and phase-stable cable, comprising a silver-plated copper center conductor, an LD-PTFE dielectric layer fixedly sleeved on the outside of the silver-plated copper center conductor, a silver-plated copper strip wrapped outer conductor fixedly sleeved on the outside of the LD-PTFE dielectric layer, a silver-plated copper wire braided shielding layer fixedly sleeved on the outside of the silver-plated copper strip wrapped outer conductor, and an FEP protective layer fixedly sleeved on the outside of the silver-plated copper wire braided shielding layer; the FEP protective layer is provided with a bending-resistant component on its outer side;

[0007] A cable local bending reinforcement component is installed on the outside of the bending-resistant component, and a wall-mounted component is installed on the cable local bending reinforcement component.

[0008] Preferably, a plurality of reserved pressing grooves are provided on the outer circumferential surface of the FEP protective layer. The reserved pressing grooves are of the same length as the FEP protective layer. The anti-bending members correspond to the reserved pressing grooves one by one, and the anti-bending members are embedded in the reserved pressing grooves.

[0009] Preferably, the anti-bending member includes an elastic plastic strip. The elastic plastic strip is a long strip with a "return" - shaped end face. The elastic plastic strip is fixed inside the reserved pressing groove. A rubber protective layer is sleeved and fixed on the outside of the FEP protective layer, and the rubber protective layer covers a plurality of elastic plastic strips.

[0010] Preferably, the cable partial anti-bending reinforcement assembly includes two groups of hoop plates. Each group of hoop plates has two. A plurality of metal anti-folding strips are fixed between the two hoop plates. Two adjacent hoop plates of the two groups are connected by a splicing member.

[0011] Preferably, the hoop plate is a semi-circular ring plate. A plurality of tooth grooves are formed on the inner circumferential surface of the hoop plate. Edge grooves are formed at both ends of the hoop plate, and the splicing assembly is installed in the edge grooves.

[0012] Preferably, the splicing assembly includes a splicing column, a metal gasket, and an anti-loosening nut. The splicing column is a semi-cylindrical column with a threaded section. The splicing column is fixed inside the edge groove. The two splicing columns at the ends of the two hoop plates are assembled into a screwed stud in a threaded connection. The metal gasket and the anti-loosening nut are both sleeved on the stud. The two hoop plates are provided with limiting clamping members at the ends.

[0013] Preferably, the limiting clamping member includes a clamping groove, an insertion strip, and a rubber clamping strip. The clamping groove is an arc-shaped groove. There are two clamping grooves, which are respectively formed at both ends of one hoop plate. Insertion strips are fixed at both ends of the other hoop plate. The insertion strips are inserted into the clamping grooves. The rubber clamping strip is sleeved and fixed at one end of the insertion strip. The rubber clamping strip is a long strip with a circular end face. The rubber clamping strip is inserted into the clamping groove, and the end face diameter of the rubber clamping strip is greater than the bottom groove width of the clamping groove.

[0014] Preferably, the wall-attached member includes an adhesive attachment and a suspension member. A flat surface is formed on the outer circumferential surface of the hoop plate, and the adhesive attachment is fixed on the flat surface.

[0015] Preferably, the adhesive attachment includes a double-sided adhesive tape and a release paper covering the double-sided adhesive tape. The double-sided adhesive tape is bonded to the surface of the flat surface. The suspension member includes two hanging pieces. The two hanging pieces are symmetric about the flat surface and are fixed on the outer circumferential surface of the hoop plate. Reserved holes are formed on the surface of the hanging pieces.

[0016] Preferably, a rubber cover is fixed between the two hoop plates, and a plurality of metal anti-folding strips between the two hoop plates are all located inside the rubber cover.

[0017] A preparation process for an anti-bending deformation stable amplitude and stable phase cable, the preparation process includes the following steps:

[0018] An LD-PTFE dielectric layer, a silver-plated copper strip wrapped around the outer conductor, a silver-plated copper wire braided shielding layer, and an FEP protective layer are set on the outer side of the silver-plated copper center conductor from the inside to the outside. A reserved pressure groove is reserved on the outer ring surface of the FEP protective layer. After installing an elastic plastic strip in the reserved pressure groove, a fixed rubber protective layer is sleeved on the outside of the FEP protective layer. The elastic plastic strip improves the cable's resistance to bending deformation.

[0019] During cable laying, two sets of clamps are installed where it is necessary to prevent the cable from bending. After the two sets of clamps are assembled, the metal anti-bending strip between the two sets of clamps forms an anti-bending reinforcement.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The present invention proposes a bending deformation-resistant amplitude and phase-stable cable and its manufacturing process, which sequentially comprises an LD-PTFE dielectric layer, a silver-plated copper strip wrapped around the outer conductor, a silver-plated copper wire braided shielding layer, and an FEP protective layer outside the silver-plated copper central conductor. This multi-layered structure works synergistically: the LD-PTFE dielectric layer possesses excellent dielectric properties, effectively ensuring signal transmission stability; the silver-plated copper strip wrapped around the outer conductor and the silver-plated copper wire braided shielding layer provide good shielding, reducing the impact of external electromagnetic interference on the cable signal; and the FEP protective layer further protects the internal structure from external environmental factors. Together, these multi-layered structures ensure that the cable maintains stable electrical performance under various operating conditions, achieving amplitude and phase-stable signal transmission.

[0022] Multiple pre-reserved grooves, the same length as the FEP protective layer, are made on the outside of the FEP protective layer. Long, elastic plastic strips with "U"-shaped end faces are embedded in these grooves. These elastic plastic strips possess excellent elasticity and resistance to deformation. When the cable is subjected to bending forces, the elastic plastic strips can undergo elastic deformation, absorbing and dispersing some of the external force. This reduces the direct impact of external forces on the internal structure of the cable, effectively preventing performance degradation due to bending and significantly enhancing the cable's resistance to bending deformation.

[0023] A localized cable bending reinforcement assembly is installed on the outside of the bending-resistant component. This assembly includes two sets of clamps, with multiple metal anti-bending strips fixed between the two clamps in each set. The two sets of clamps are then fastened to the area of ​​the cable requiring bending reinforcement, ensuring that the portion of the cable to be prevented from bending is positioned between the two clamps in the same set. The clamps are then securely fixed to the cable using splicing components and limiting clips. The toothed grooves on the inner circumference of the clamps engage with the outer wall of the cable, enhancing the installation's stability. The multiple metal anti-bending strips positioned between the two clamps effectively resist external forces, preventing bending of the cable in this area and providing reliable localized bending reinforcement protection for the cable.

[0024] The cable partial bending reinforcement assembly is equipped with wall-mounted components, including adhesive attachments and suspension components. The adhesive attachments have double-sided adhesive that adheres to the outer ring surface of the clamp plate. During cable laying, after removing the release paper, the cable can be quickly bonded to the ground or wall surface for initial positioning. The two hanging plates of the suspension component are symmetrically fixed to the outer ring surface of the clamp plate about a plane. Expansion bolts are inserted into pre-drilled holes on the hanging plate surface and screwed into the holes in the mounting base, firmly fixing the hanging plates to the base surface, thereby pulling the clamp plate to limit the cable's movement. This wall-mounted component design makes cable laying and installation more convenient and stable, improving installation efficiency and quality.

[0025] Because this cable's structural design fully considers resistance to bending deformation and localized bending reinforcement, it effectively reduces internal structural damage caused by bending during use, slowing down the rate of cable performance degradation. Simultaneously, the rubber protective layer covering the elastic plastic strip and the rubber cover protecting the metal bending strip further enhance the cable's protective capabilities, enabling it to operate stably for extended periods in complex environments, thereby extending its service life and reducing operating costs.

Specific implementation manners

[0034] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some but not all of the embodiments of the present invention, and are only used to explain the embodiments of the present invention, rather than limiting the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] Embodiment 1. Please refer to Figures 1 to 7 , the present invention provides a technical solution: a stable amplitude and stable phase cable resistant to bending deformation, including a silver-plated copper center conductor 1. An LD-PTFE dielectric layer 101 is sleeved and fixed on the outer side of the silver-plated copper center conductor 1. A silver-plated copper tape-wound outer conductor 102 is sleeved and fixed on the outer side of the LD-PTFE dielectric layer 101. A silver-plated copper wire braided shielding layer 103 is sleeved and fixed on the outer side of the silver-plated copper tape-wound outer conductor 102. An FEP protective layer 104 is also sleeved and fixed on the outer side of the silver-plated copper wire braided shielding layer 103; an anti-bending member is provided on the outer side of the FEP protective layer 104; a plurality of reserved pressing grooves 105 are provided on the outer ring surface of the FEP protective layer 104. The reserved pressing grooves 105 are of the same length as the FEP protective layer 104. The anti-bending members correspond to the reserved pressing grooves 105 one by one, and the anti-bending members are embedded in the reserved pressing grooves 105; the anti-bending member includes an elastic plastic strip 106. The elastic plastic strip 106 is a long strip with a "return" shaped end face. The elastic plastic strip 106 is fixed inside the reserved pressing groove 105. A rubber protective layer 107 is sleeved and fixed on the outer side of the FEP protective layer 104. The rubber protective layer 107 covers a plurality of elastic plastic strips 106.

[0036] This anti-bending deformation, amplitude- and phase-stable cable features an ingenious structural design. On the outside of the silver-plated copper center conductor 1, an LD-PTFE dielectric layer 101, a silver-plated copper tape-wrapped outer conductor 102, a silver-plated copper wire braided shielding layer 103, and an FEP protective layer 104 are sequentially arranged. This multi-layered structure collaboratively ensures the cable's stable electrical performance. A pre-reserved pressure groove 105 is opened on the outside of the FEP protective layer 104, and an elastic plastic strip 106 is installed, significantly enhancing the cable's resistance to bending deformation and effectively preventing performance degradation caused by bending. A rubber protective layer 107 is then added to cover the elastic plastic strip 106, further providing reliable protection for the cable and ensuring that it maintains its amplitude- and phase-stable characteristics even in complex operating environments, thus extending the cable's service life.

[0037] To straighten and limit the bending of sections of the cable, the following method was proposed:

[0038] A cable local bending reinforcement component is installed on the outside of the bending-resistant component. The cable local bending reinforcement component includes two sets of clamp plates 2, each set of clamp plates 2 has two clamp plates, and multiple metal anti-bending strips 3 are fixed between the two clamp plates 2. The two adjacent clamp plates 2 are connected by a splicing component. The clamp plate 2 is a semi-circular ring plate, and multiple toothed grooves 201 are opened on the inner ring surface of the clamp plate 2. Side grooves 202 are opened at both ends of the clamp plate 2, and the splicing component is installed in the side grooves 202. A rubber cover 301 is fixed between the two clamp plates 2, and the multiple metal anti-bending strips 3 between the two clamp plates 2 are all in the rubber cover 301. The splicing component includes a splicing column 203, a metal washer 204, and an anti-loosening nut 205. The splicing column 203 is a semi-cylinder with a threaded section, and the splicing column 203 is fixed in the inner side groove 202. The two hoop plates 2 have two splicing posts 203 at their ends that are joined together to form a threaded stud. Metal washers 204 and anti-loosening nuts 205 are both fitted onto the stud. The two hoop plates 2 have limiting clips at their ends. The limiting clips include a slot 206, an insert 207, and a rubber clip 208. The slot 206 is an arc-shaped groove. There are two slots 206. The two slots 206 are respectively opened at both ends of one hoop plate 2. The insert 207 is fixed at both ends of the other hoop plate 2. The insert 207 is inserted into the slot 206. The rubber clip 208 is fitted and fixed at one end of the insert 207. The rubber clip 208 is a long strip with a round end face. The rubber clip 208 is inserted into the slot 206. The diameter of the end face of the rubber clip 208 is larger than the width of the bottom groove of the slot 206.

[0039] Two sets of clamp plates 2 are fastened to the area of ​​the cable that requires bending reinforcement, i.e., the part of the cable that needs to be prevented from bending is located between the two clamp plates 2 in the same set. The ends of the two sets of clamp plates 2 are aligned and assembled by engaging rubber clips 208 through slots 206. Then, metal washers 204 and anti-loosening nuts 205 are put on the studs and screwed in to lock them, thus completing the fixation of the two sets of clamp plates 2 to the cable. The toothed grooves 201 engage with the outer wall of the cable, making the two clamp plates 2 firmly installed on the cable. Multiple metal anti-bending strips 3 are located between the two clamp plates 2 to prevent bending of the cable area between the two clamp plates 2.

[0040] To facilitate cable laying and installation, the following was proposed:

[0041] The cable partial bending reinforcement assembly is equipped with a wall-mounted component; the wall-mounted component includes an adhesive attachment and a suspension component. The outer ring surface of the hoop 2 has a plane 209, and the adhesive attachment is fixed on the plane 209; the adhesive attachment includes a double-sided adhesive 4 and a release paper 401 covering the double-sided adhesive 4. The double-sided adhesive 4 is bonded to the surface of the plane 209. The suspension component includes two hanging pieces 5. The two hanging pieces 5 are symmetrical about the plane 209 and fixed to the outer ring surface of the hoop 2. The surface of the hanging pieces 5 has a reserved hole 501.

[0042] After the cable is fitted with clamp plate 2, during cable laying, the release paper 401 is peeled off from the double-sided adhesive 4, and the cable is pushed to stick the double-sided adhesive 4 to the ground or wall surface. In order to fix the cable to the mounting base, a hole is drilled in the mounting base through the reserved hole 501. Then, the expansion wire is passed through the reserved hole 501 and screwed into the hole in the base. The hanging plate 5 is fixed to the base, and the hanging plate 5 pulls the clamp plate 2 to limit the cable.

[0043] Application method of amplitude and phase stable cable with bending deformation resistance

[0044] This resistant, amplitude- and phase-stable cable exhibits excellent bending resistance and convenient installation. Its usage will be detailed below:

[0045] This cable uses a silver-plated copper center conductor 1 as its core, with a series of fixed multi-layer structures surrounding it. First, an LD-PTFE dielectric layer 101 is applied, which effectively ensures the stability of the cable's electrical performance. Next, a silver-plated copper tape-wrapped outer conductor 102 is applied, further enhancing the cable's transmission performance. Then, a silver-plated copper wire braided shielding layer 103 is applied, effectively shielding against external interference and ensuring the stability of signal transmission. Finally, an FEP protective layer 104 is applied, providing reliable protection for the internal structure.

[0046] Multiple pre-drilled grooves 105 are formed along the length of the outer circumference of the FEP protective layer 104. The pre-drilled grooves 105 are the same length as the FEP protective layer 104. Long, elastic plastic strips 106 with "U"-shaped end faces are embedded one by one into the pre-drilled grooves 105 and firmly fixed, thereby significantly enhancing the cable's resistance to bending deformation and preventing performance degradation due to bending. Then, a fixing rubber protective layer 107 is fitted over the outside of the FEP protective layer 104, ensuring that the rubber protective layer 107 completely covers the multiple elastic plastic strips 106, providing further reliable protection for the cable and ensuring that the cable maintains stable amplitude and phase characteristics even in complex operating environments, thus extending its service life.

[0047] When straightening and limiting the bending of a cable in a localized area requires correction, a localized cable bending reinforcement assembly is used. This assembly includes two sets of clamps 2, each set consisting of two clamps. Multiple metal anti-bending strips 3 are fixed between the two clamps 2. Two adjacent clamps 2 are connected by splicing components. The two sets of clamps 2 are fastened onto the area of ​​the cable requiring bending reinforcement, ensuring that the section of the cable to be bent is positioned between the two clamps 2 of the same set. The clamps 2 are semi-circular rings with multiple grooves 201 on their inner surface for engaging with the outer wall of the cable, making the clamps 2 more secure. The ends of the two sets of clamps 2 are aligned and spliced ​​using limiting clips. The specific operation involves inserting the insert strip 207, fixed at both ends of one clamp plate 2, into the slots 206 opened at both ends of another clamp plate 2. Simultaneously, a long, round-faced rubber clip 208, fitted and fixed to one end of the insert strip 207, is also inserted into the slot 206. Since the end diameter of the rubber clip 208 is larger than the width of the bottom opening of the slot 206, a secure connection is ensured. After splicing, the two splicing posts 203 at the ends of the two clamp plates 2 are assembled into threaded studs. Metal washers 204 and anti-loosening nuts 205 are then sequentially fitted onto the studs and tightened, completing the fixation of the two sets of clamp plates 2 onto the cable. At this point, multiple metal anti-bending strips 3 are positioned between the two clamp plates 2, effectively preventing cable bending in this area. Furthermore, a rubber cover 301 is fixed between the two clamp plates 2, with the multiple metal anti-bending strips 3 all within the rubber cover 301, providing protection for the metal anti-bending strips 3.

[0048] After the cable clamp 2 is installed, the cable laying and installation work can begin. The wall-mounted components installed on the cable local bending reinforcement assembly facilitate convenient installation. The wall-mounted components include adhesive attachments and hanging components. A flat surface 209 is provided on the outer ring of the clamp 2, and the adhesive attachments are fixed to this flat surface 209. The adhesive attachments include double-sided adhesive tape 4 and release paper 401 covering the double-sided adhesive tape 4, which is adhered to the surface of the flat surface 209. During cable laying, the release paper 401 is peeled off the double-sided adhesive tape 4, and then the cable is pushed to adhere the double-sided adhesive tape 4 to the ground or wall surface, achieving initial fixation. To more firmly fix the cable to the mounting base, a tool is used to drill a hole in the mounting base through the pre-drilled hole 501. Then, an expansion bolt is passed through the pre-drilled hole 501 and screwed into the hole in the base. The hanging plate 5 is then fixed to the base. The hanging plate 5 pulls the clamp 2 to limit the cable's position, ensuring a stable cable installation.

[0049] Example 2, based on Example 1, proposes a manufacturing process for a bending deformation-resistant amplitude- and phase-stable cable, including the following steps:

[0050] An LD-PTFE dielectric layer 101, a silver-plated copper strip wrapped outer conductor 102, a silver-plated copper wire braided shielding layer 103, and an FEP protective layer 104 are provided on the outer side of the silver-plated copper center conductor 1 from the inside to the outside. A reserved pressure groove 105 is reserved on the outer ring surface of the FEP protective layer 104. After installing an elastic plastic strip 106 in the reserved pressure groove 105, a fixed rubber protective layer 107 is sleeved on the outside of the FEP protective layer 104. The elastic plastic strip 106 improves the cable's resistance to bending deformation.

[0051] During cable laying, two sets of clamps 2 are installed where it is necessary to prevent the cable from bending. After the two sets of clamps 2 are assembled, the metal anti-bending strips 3 between the two sets of clamps 2 constitute anti-bending reinforcement.

After the two sets of clamps (2) are assembled, the metal anti-bending strip (3) between the two sets of clamps (2) constitutes anti-bending reinforcement.
